Title: Soil-tilling implement with following levelling discs
Inventor: LAAK THEO VAN ING GRAD
IPC: A01B35/18
Filed: 1986-09-26
Abstract: In a soil tilling implement the ridges 8 and furrows 5 produced by tines 3,4 are levelled by rotatably mounted hollow discs 6,7 secured to the chassis 2 so that the domed faces of a pair of discs are towards each other and in such a way that their hollow surfaces facing obliquely forward throw the earth back into the furrows. The hollow discs work above the tilling plane of the tines and are arranged offset in relation to one another in the direction of travel, so that the movement of the hollow discs cannot be disturbed by clods and the like lumps. The angle of inclination of the disc axes to the ground and the angle of the disc axes to the direction of travel are each variable. <IMAGE>

Title: Automotive engine output control linkage with a wheel slip override
Inventor: SEIBERT DR WOLFRAM
IPC: F02D11/04
Filed: 1987-01-19
Abstract: A control pedal 1 is connected to the output determining member, e.g. throttle valve 5, through levers 6,7 or discs having respective stops 9,10 urged into engagement by a spring 8. A device 11 responsive to wheel spin is connected to the lever 7 or disc to provide relative movement between the levers or discs when wheel slip is detected in order to reduce engine output. One of the levers (19, Fig. 2) may form an extension of the pedal lever (1') and a kick-down switch (31, Fig. 4) and a cruise control (32) may be permanently coupled to the pedal to be unaffected by and not affect the override. A freewheel between the lever 7 and the device 11 prevents the device from stopping pedal initiated power output reduction. <IMAGE>

Title: Apparatus for helping the disabled to stand from a sitting position
Inventor: JAMES DAVID RICHARD
IPC: A61H3/00
Filed: 1987-04-21
Abstract: Apparatus of Figure 3 comprises a support structure in the form of a frame 31 and releasable anchorage means comprising a footplate 32. The frame has front and rear support legs, 33 and 34, the front legs 33 being engageable with the footplate 32 via brackets 36 to anchor the frame 31 to the ground with the feet of a user resting on the footplate 32.

Title: Optical fibre sensor
Inventor: EPWORTH RICHARD EDWARD
IPC: G01S17/02
Filed: 1988-03-08
Abstract: To overcome polarisation mismatch fading problems in an optical fibre sensor system with multiple refection points (R0 to Rn) equally spaced along a sensor fibre (10) the return signal (11) is divided into two portions (12, 13) which are separately heterodyned. One of the local oscillator signals (16) is arranged to be polarisation-state matched with its return signal (13) wherever the other return signal (12) is orthogonally polarised with respect to its local oscillator signal (17). Signal processing involves delaying (24, 26) each detected signal by the round trip transit time between adjacent reflectors (R) and combining it (25, 29, 30, 31) with each undelayed detected signal. <IMAGE>

Title: A tandem warhead
Inventor: TRIPPTRAP PETER
IPC: F42C11/06
Filed: 1990-06-19
Abstract: A tandem warhead (10) for use against active armoured targets (20), has a detonation delay unit which controls the detonation time Êt between the first and the second charges. A device (17) is provided for determining the angle of the warhead (10) in relation to the target (20) and setting the detonation delay time to the measured angle Î± of attack. To determine the angle of attack the device(17) is associated with four range finders (31-34) by means of which the distance between the tandem warhead (10) and the target (20) is ascertained. The delay time is then determined by means of a characteristic curve function Êt=f(Î±) specific to the warhead(10). Determination of the angle Î± may be used to control flight by changing the direction of the warhead towards an optimum angle.
