Patent GB-2019148-A (GB)
Title: Voltage-to-current converter
IPC: H03F3/30
Filed: 1979-03-20
Abstract: A voltage-to-current converter with improved power supply rejection ratio includes an output operational amplifier A2 to substantially supply the power requirements of a load, the output operational amplifier being powered by an unregulated power supply. The output of the operational amplifier is supplied to the load at a predetermined gain which may be defined by a feedback loop z2/z1. This output operational amplifier is supplied by an additional low-power, high-gain amplifier A1 having very good power supply rejection ratio. The input amplifier has high gain at DC and up to the power supply frequency and including the first few harmonics thereof. The input amplifier is stabilized at high frequency by the provision of feedback loops R1, R2, C1 which limit the gain of the input amplifier at high frequencies. The feedback loop, however, is so designed as not to interfere with the DC and low frequency gain of the amplifier. <IMAGE>

Patent GB-2037219-A (GB)
Title: Reproducing wood carvings in plastics
IPC: B44F9/02
Filed: 1979-11-27
Abstract: A light-coloured wood is carved to produce a master pattern, to which a flexible moulding compound e.g. silicone rubber is applied to form a mould.

Title: Seed planter
IPC: G01V3/12
Filed: 1980-08-08
Abstract: A seed planting apparatus comprises a mobile planting machine (110) to be connected to a tractor or similar vehicle, and having a seed hopper (112) for containing a supply of seeds to be planted. A seed outlet on the hopper feeds a seed dispensing apparatus (126) for delivering seeds to the ground to be planted. A microwave seed sensing apparatus is disposed in a path of travel for seeds discharged from the hopper for detecting the seeds and producing an observable indication to the operator of the presence of seeds in the path of travel. The seed planting apparatus may also include magnetic seed treatment apparatus (201). The microwave sensing apparatus may therefore be connected in a control circuit for actuating the magnetic field in response to the presence of seeds and for producing an indication to an operator of the passage of seeds. <IMAGE>

Title: Bale accumulator
IPC: A01D85/00
Filed: 1980-10-22
Abstract: A bale accumulator adapted to be towed behind a baling machine comprises a collating part (10) and a storage part (11) is adapted to collate an array of eight bales arranged such that four bales are juxtaposed inside- by-side relationship, the ends of the four bales defining two substantially parallel edges along each of which two further bales are arranged in mutual end-to-end relationship. The collating part (10), which comprises three channels (20), (21), (22), collates a first sub-group of four bales and automatically releases the first sub-group through the gate (12) into the storage part (11). The collating part (10) then forms another sub- group being the complement of the array and releases said sub-group to form the complete array in the storage part (11) which may then be manually released from the storage part (11) through gate (13) when desired. The bales may be formed into the array by movable defector gates (17), (18) and a turning gate (19), movement of which may be caused by relative motion between the ground and the bales. <IMAGE>

Title: Electrical harness forming machine and process
IPC: H01B7/08
Filed: 1980-12-16
Abstract: An electrical wiring harness is formed as a flat tape by securing individual leads side-by-side-by a bonding material which is itself in the form of tape. With the bonding material in a potentially bond-forming condition, for example softened by hot air blowers or by a solvent, the leads and the bonding material are combined by pressure in a roll nip. It is known to lay the leads out along a work top and move a heating and combining unit along the leads to form the harness. However, the machine is very long, requires turntables at each end to turn the combining unit, and leaves the harness in an inconvenient form for further handling. The leads and bonding material 12 are drawn past combining means, e.g. rollers 40, 24, 26, by a winding drum 22, which winds up into the form of a coil a harness so formed. <IMAGE>

The levelling system is thereby rendered sensitive only to pitch and roll of the vehicle due, for example, to braking, acceleration, or external lateral forces, and not due to wheel movements over irregular ground. <IMAGE>

Title: Means for sewing together workpiece parts by means of a bead seam
IPC: D05B27/02
Filed: 1979-02-02
Abstract: In a machine for sewing together two parts or layers of a workpiece having equal or unequal length, in which one part is folded over the other prior to sewing, the folding and forming is performed as a single operation and the folding means is in the form of a guide roller (198) having a shaped profile which also acts as an edge guide. The roller (198) is mounted on a carrier 206, 210 pivotable about an axis 88 by means of an over-run element which blocks rotation of the roller when the carrier moves in the feed direction and permits the roller to rotate in the opposite direction of motor of the carrier while the needle (12) is forming a stitch in order to prefold the protruding edge of the workpiece layer over the other layer. The profile of the collar (198) acts as a guide for the edge of the workpiece and at the same time presses downwards to press the workpiece layers together. <IMAGE>
