The present invention relates to improvements in or relating to vegetation cutter apparatus. In particular, it relates to improvements in construction and manufacture of housings for lawn mowers. We describe a lawnmower having a deck with a lower surface defining a cutting chamber, a cutting element mounted within the cutting chamber, a motor assembly driving the cutter element, the motor being mounted on an upper surface of the deck, wherein the vegetation cutting apparatus further comprises a discharge chute having a discharge chute inlet in communication with the cutting chamber and a discharge chute outlet, a cover covering at least a portion of the motor assembly, and a pivotable deflector guard biased into a closed configuration against the discharge chute outlet. The discharge chute comprises a chute floor, chute sides and a chute roof. The present invention is characterised in that at least a portion of the chute roof is formed by a portion of the motor cover.

The invention concerns a device (1) for manipulating tools comprising two parts, said device being of the type consisting of a frame and at least one tray forming a table, designed to receive the mold. The invention is characterized in that it comprises two horizontally arranged trays (6, 9-7, 8) one of which is arranged sliding on the frame to be mobile in translation relative to the other tray, from a close position to a remote position and inversely, so as to enable the tool to be manually opened and closed.

A manually-actuated device for the deliver of a volume of liquid which includes an outlet through which liquid is in use delivered and a cover member which is movably disposed relative to the housing between a first position in which the cover member at least partly covers the outlet and a second position in which the cover member acts as a lever which in use is acted upon by a user to actuate the delivery device.

The present invention relates to a CVD-coated cutting tool insert with a TiC x N y -layer with a low tensile stress level of 10-300 MPa and an ±-Al 2 O 3 -layer with a high surface smoothness of <0.1 µm as measured by AFM-technique. This is obtained by subjecting the coating to a first intensive wet blasting operation with a slurry consisting of F80 grits of Al 2 O 3 followed by a second wet blasting treatment with a slurry of F320 grits of Al 2 O 3 .

The invention relates to a directional antenna mechanism of a mobile radio tracking receiver, comprising four antenna elements (12), which are fastened by a pivot pin (14) to the body (10) of the radio tracking receiver. For the duration of the use, the antenna elements are turned to an operating position, in which they are pointed away from the body. After use, the antenna elements can be turned to a transport position, in which the antenna elements are placed inside the body in the direction of the longitudinal axis of the body. In the invention, at least two antenna elements are connected to each other by a mechanism in a way that moving the first antenna element to the operating position or the transport position also causes the second antenna element to move to the same position simultaneously. Preferably, all the antenna elements are connected to each other by a mechanism in a way that moving one antenna element to the operating position or the transport position causes all the antenna elements to move to a corresponding position simultaneously. The mechanism according to the invention comprises a movable transmission rod (16) arranged inside the body, with toothings (26) and toothed discs (22) fastened to the ends of the antenna elements, contacting to the toothings of the transmission rod. The transmission rod is moved either manually by a lever (28) fastened to the transmission rod or by an actuator, such as an electric motor, arranged inside the body.

1. A bucket excavator (1) having an arm system (6) carrying a work tool (21) preferably formed as a ditcher (20) which has a dipper arm (30) fixed to a pivotable beam (12) and which can be folded generally in a vertical plane to a transport position and is adjustable from this position to an extended position, by means of a pivot drive connected to the beam (12), which engages with a dipper arm connection (15) on the free end of the dipper arm (30), characterised in that a pair (31) of alternately loadable traction cylinders (32, 33) is provided as the pivot drive, of which one serves for extending the dipper arm (30) and by means of a flexible traction means (49) is connected to the free end of the dipper arm (17), whilst the other traction cylinder (32) serves for folding the arm system (6) and is connected by a flexible traction means (38) between the connections (15, 19) of the dipper arm (30) and the work tool (21) to the dipper arm (30), and that both traction means (38, 49) on the beam (6) are guided between the dipper arm connection (15) and the beam connection, in which a rocker arm (53) fixed to the dipper arm (30) in the extended position of the dipper arm (30) turns the traction means (38) of the traction cylinders (32) serving for folding of the arm system (6) and in the folded position of the arm system (6) turns the traction means (49) of the traction cylinder (33) serving for the extension around the axis (16) of the dipper arm connection (15) by means of a curve (55).

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).
