Title: Towing vehicle for the manoeuvring of aircraft
Inventor: CUERTEN FRANZ JOHANNES DIPL IN
IPC: B64F1/22
Filed: 1988-01-22
Abstract: A towing vehicle for the moving of aircraft without a towbar has a chassis (5) which has a fork-shaped retention space between the wheels of one wheel axis, in which retention space there is arranged a gripping and drawing-in device (28, 68) which interacts with a lifting device and can be extended and withdrawn, by means of which the nose wheel (24) of the aircraft can be gripped and can be drawn onto a blade (14) which can be raised and lowered relative to the chassis. In this case, only a single blade (14) is provided to support the nose wheel (24) in the region of the line in which the nose wheel load acts, in order to avoid jamming and deformation forces on the nose wheel (24) during the drawing-in process or during lifting. The blade can in this case be tilted about a horizontal axis arranged on the chassis, and its tilting position can be adjusted in a controlled manner relative to the chassis. In a development, the blade can also be inclined at an angle to the horizontal axis in order to prevent unacceptable stresses being applied when the towing vehicle is cornering with a nose wheel loaded on it. The articulation of the blade is preferably carried out on the chassis, via a parallelogram linkage (70, 71, 73, 74), or a trapezoidal linkage. <IMAGE>

Title: Tripping device for electrical power-distribution switch
Inventor: DIRKS ROLF
IPC: H01H71/12
Filed: 1988-07-23
Abstract: For the protection of distribution transformers in medium-voltage systems, load interruptors and high-voltage high-rupturing capacity (h.v.h.r.c, HH) fuses are geneally used. Instead of HH fuses, a power switch can also be used. This considerably increases the expenditure on components. The invention relates to a tripping device, wherein a switch 2 for a distribution transformer 1 is provided with a tripping device 4 which requires considerably fewer components than hitherto. This occurs by the current causing the tripping immediately destroying or weakening a component used for the latching and thereby causing the break. For this purpose, a retaining wire 41 is provided which is tensioned by a tripping spring 42. A latch 43 is connected to the retaining wire 41, which latch is unlocked in the event of tripping. A tripping device of this kind can in particular be used for power switches whose purpose is to protect a distribution transformer. <IMAGE>

Title: Tearing-off appliance for hop shoots
Inventor: SOLLER JOSEF
IPC: A01D46/02
Filed: 1988-08-16
Abstract: The invention relates to a tearing-off appliance for hop shoots, which has, among other things, transverse transport which is formed essentially from a disc resembling a belt pulley and from a band-shaped and driven counterpressure means surrounding approximately half of the latter, both the disc and the counterpressure means possessing profiles which engage in one another and which fix between them the shoot ends and their climbing-wire ends in a deforming manner. According to the invention, an appliance of this type is to be improved to the effect that the holding forces for the shoot ends and especially for the climbing-wire ends are so high that a tearing-off of the shoots and, above all, of the climbing wires from the bracing wires is ensured at all events. This is achieved in that the rotating counterpressure means (18) is assigned a further counterpressure means (for example, 31) which has high longitudinal stability and which runs in a groove (29) of the disc (16) and in grooves (30) of deflecting rollers (20-23), especially in grooves (30) of the deflecting rollers (20, 23) for the counterpressure means (18). <IMAGE>

Title: Cleaned air discharge unit of cyclone floor and dip tube - completely removable from cyclone to aid removal of trapped powder
Inventor: KRAEMER ERICH
IPC: B05B14/48
Filed: 1989-05-11
Abstract: Particles are sepd. from entraining gas, esp. air by centrifugal force inside a cyclone (10). Purified air emerges from a dip tube (14) inserted from the head of the cyclone while sepd.  particles fall to the cyclone floor to be removed, possibly for re-use, while the cyclone interior is cleaned by scouring air. Since in practice some particles lodge in the space between the dip tube and the cyclone wall, such scouring is sometimes ineffective. This is countered by making the dip tube (14) integral with a floor section (26) of the purified gas conduit (16), forming a unit separably removable for cleaning while the remainder of the cyclone is scoured. The two elements may be screwed or welded together, or a push fit. The dip tube may be replaced by a filter insert (40), cleanable by vibration. USE/ADVANTAGE - Esp. for powder spray booths, where change of colour necessitates complete intermediate cleaning.
