The residual pressure valve comprises a rubber tube (2) which acts as a valve seat and holds the gas control component (1) under tension. The control component has chambers (1H1, 1H2) at each end which are connected by vertical channels (K1A, K1B, K2A, K2B) to control chambers (SA, SB) on its lower side. These are separated by a radial partition (ZW).

1. A single-spindle or multi-spindle deep boring machine having a tool change device characterised in that the device (7) is formed by cylindrically arranged receiving tubes (8), wherein along a part of the length of the receiving tubes (8) the cross-section thereof is removed over an angle of somewhat more than 180 degrees, in such a way that for the purposes of receiving a deep boring tool (3, 3') perpendicularly to the axis of the receiving tube (8), wherein the inside diameter thereof is substantially equal to the diameter of the deep boring tool (3, 3'), an open half-shell is formed, from which the deep boring tool can be pushed into the remaining part in the axial direction of the receiving tube (8).

This invention relates to a method for manufacturing a metal tubular blank suitable for forming into a product comprising the steps of providing an essentially planar blank, said planar blank having a first surface and a second surface; producing the tubular blank from the planar blank whereby the second surface of the planar blank becomes the outside of the tubular blank; wherein a first layer with a first friction influencing function is applied to at least part of the first side of the planar blank and/or a second layer with a second friction influencing function is applied to at least part of the second side of the planar blank prior to forming the planar blank into a tubular blank, so as to influence the friction between the tubular blank and forming tools which can be used to form the tubular blank into the product, and wherein the first and/or second layer are applied in the form of a foil, a dry lubricant, a wax or an oil. The invention further relates to a tubular blank and a product produced from such a tubular blank.

1. An automatic liquid-raising device with a storage tank (3) positioned above a closed working chamber (1), and a closed suction chamber (2) positioned above the storage tank (3) and having an outlet for liquid ; the working chamber (1) having a drain pipe (5) extending a certain distance downwards from its bottom and a suction-transfer pipe (7) rising from its top to the suction chamber (2) ; the storage tank (3) being connected through a charging pipe (6) to the working chamber (1) ; the suction chamber (2) having a feed pipe through which it aspirates liquid ; the charging pipe (6) having a valve (6a) for controlling the flow of liquid reaching the working chamber (1) from the storage tank (3) in dependence on the amount of liquid in the working chamber (1) ; the suction chamber (2) having a non-return valve (16) in its outlet (2a) for preventing return flow of liquid back into the suction chamber (2), characterised in that the storage tank (3) is mounted directly on top of the working chamber (1) and delivers working liquid through a charging pipe (6) to the top of the working chamber (1), the charging pipe (6) penetrating into the interior of the storage tank (3) ; the charging pipe (6) having a downwards-directed mouth (6a, 6a') cooperating with a valve plate (13, 23) actuated by a device (9, 12 or 24, 25) controlled by an actuator (9, 25) located in the working chamber (1) ; the actuator (9, 25) being connected to the valve plate (13, 23) through at least one sealed aperture (12, 24) in the separation wall (3a) between the storage tank (3) and the working chamber (1).

Liquid wax passes through an inlet valve (1) leading to a line (2) connected to a pressure regulator (3). The wax then passes through a flow measurement device (4) to a pre-atomization system (14) mixing liquid wax with air under pressure. The air enters via an inlet valve (6) leading to a line (5) connected to filters (7,8), a pressure measurement device (9) and a control valve system (22) with three 5/2-way valves (15,17,21) and two pressure regulators (16,18). The size of the droplets of wax produced by the pre-atomization system may be controlled. The wax mist may be fed through a valve (20), which admits extra air (11), to the spray lance (19).

The invention relates to the field of materials science and to high-strength planar structures for the protection of vehicles and people. The aim of the invention is to provide high-strength planar structures which are characterized in that the planar structure is only destroyed in the immediate vicinity of an impact. This aim is achieved by a high-strength planar structure that consists of individual elements that give, applied to a backing material, the high-strength planar structure. The individual elements have the shape of regular pyramids and tetrahedrons or irregular pentahedrons and/or hexahedrons and/or the individual elements consist of combined and interlinked shapes (compound shapes) of regular pyramids and tetrahedrons or irregular pentahedrons and/or hexahedrons. The aim is also achieved by a method which is characterized in that individual elements and/or shapes (compound shapes) combined from such individual elements and interlinked are combined to give a planar structure and are non-positively linked with a backing material at least on one side.

The method comprises the formation of a liquid metal wherein is introduced a coated wire of which the core contains a material consisting of a calcium alloy, said alloy containing at least 75% by mass of calcium and a total contents of at least 5% by mass of NI + Al. Preferred composition: at least 80% of calcium and up to 20% of Ni and/or Al. The tests carried out by means of the device represented in figure 1 have shown that it is possible to effect the introduction of the coated wire (10) into the flowing steel (2) at a rate from 80 to 120g of Ca per ton of flowing steel and per minute without causing an excessive boil. The invention also relates to the coated wire.

A seal (1) protects a hot-gas/gas-pressure-sensitive element (10) from a flow (8) of hot gas and has a means (2a) of generating a sectional flow so as to create a sectional flow (8a) of hot gas in the flow of hot gas. Downstream to this, a channel (2) reduces mass flow rate in the sectional flow. A means (3) of expansion expands the sectional flow according to volume. An independent claim is also included for a method for protecting a hot-gas/gas-pressure-sensitive element in a heavy-duty circuit breaker from a flow of hot gas.

A valve assembly comprising a chamber, the chamber having an inlet which is adapted to be connected to a source of relatively high pressure fluid, and an outlet which is adapted to be connected to a source of relatively low pressure fluid, and a switch valve which is switchable between a first configuration in which the valve closes the outlet and opens the inlet, and a second configuration in which the valve closes the inlet and opens the outlet, characterised in that a flow control device is provided between the outlet and the volume of relatively low pressure fluid, the flow control device including a restrictor portion which restricts flow of fluid through the flow control device, the extent to which fluid flow is restricted decreasing as the fluid pressure in the chamber increases.
