Title: Controlling implement depth
IPC: A01B63/112
Filed: 1979-12-18
Abstract: A device for controlling the working depth of a soil cultivating implement, for example a plough. articulated to a tractor comprises a shaft 1 which at its ends is fixed via splines 11a, 11b in the gearbox casing 4 of the tractor. The shaft 1 has a substantially rigid middle portion 1b and two outer end portions 1a and 1c which are of smaller diameter than the middle portion 1b and each of which is constructed as a torsion bar. The respective ends of the middle portion 1b have splines 2, 3 which carry cranks 9 and 10 respectively connectible to a link member of the plough. An element 13, mounted on the middle portion 1b intermediate its ends, serves to transmit, to a control device of a power lift on the tractor, variations in the traction and/or bearing values of forces acting on the cranks 9 and 10, and which are summated via the middle portion 1b of the shaft 1. <IMAGE>

Title: Detection of the presence of a vehicle
IPC: G08G1/042
Filed: 1979-12-19
Abstract: A vehicle detector has an inductive sensing loop (11) that is a frequency determining element of an oscillator (10). A first counter (210) fed from clock source 20 is operated to sample the oscillator period and the count achieved is applied as a preset reference to a second down counter (230) also fed from source 20 which is counted down in each sample period. The residue in the second counter at the end of a sample period is examined by detection logic (250) to determine the presence of a vehicle. Upon vehicle detection the first counter is frozen at the value preceding detection, the second counter continuing operation. During vehicle detection third and fourth counters (310 and 330) are operated in the manner of the first and second counters respectively before detection, detection logic (350) examining the residues in the fourth, down, counter for ambient change during vehicle presence, to generate control signals for incrementally adding or subtracting from the count values in the first and third counters, thus the second counter is consequently preset with the predetect value of the first counter as adjusted for ambient change to enable vehicle departure to be detected. <IMAGE>

Title: Movable Target
IPC: F41J9/02
Filed: 1980-02-18
Abstract: A target display is mounted on a carriage (4) which is propelled along a longitudinally extending beam (2) by means of a motor driven wire and pulley system. The target can be moved from an observable position to an unobservable position and vice versa by rotating the beam and hence the carriage itself by means of an electro-hydraulic drive unit (11) located at the end of the beam. In one embodiment the beam is constructed from a plurality of beam sections longitudinally connected to form a continuous track of any desired length. The beam is supported by longitudinally spaced pedestals which connect adjacent beam sections and provide a bearing for rotation of the beam. The pedestals are constructed to ensure that the carriage may run along the beam and the beam can be rotated without the carriage fouling the pedestals. The raising and lowering of the target and movement along the beam may conveniently be controlled by short wave radio and the apparatus may be powered by a standard 12v car battery. <IMAGE>

Title: Animal bedding material
IPC: A01K1/015
Filed: 1980-11-08
Abstract: This invention provides bedding material or litter for small animals such as poultry, consisting of short strips or pieces of absorbent non-toxic paper.
