Patent GB-2044499-A (GB)
Title: Data processing system
IPC: G06F13/18
Filed: 1980-03-12
Abstract: In a data processing system central processor units (10 and 10A), input/output units (12), memory units (11) and secondary storage units (24, 25 and 26, 27), are interconnected by a bus (14). During an information transfer, one unit, for example processor unit (10), issues instructions including a LOCK instruction and an UNLOCK instruction. Each unit includes switching means responsive to the instructions such that, if the processor unit (10) issues a LOCK instruction, the units other than the processor unit (10) are prevented from transferring information over the bus with a L0CK instruction until an UNLOCK instruction is issued by any of the units. <IMAGE>

Title: Apparatus for applying chemicals to weeds and plants
IPC: A01M21/04
Filed: 1980-11-01
Abstract: A boom for applying chemicals to plants comprises a plurality of reservoirs (10) each in the form of a length of tubing adapted to serve as a reservoir for liquid chemical and having apertures in a wall thereof through which a plurality of wicks (12) extend for exposure to plants.

Title: Door structure
IPC: E06B11/04
Filed: 1981-03-20
Abstract: One upstanding edge of a door 4 is loosely connected to a building structure, e.g. by rings 6, so that the edge is capable of limited movement in every direction and so that the door 4 is swingable for opening and closing. Ground-engaging rolling members, e.g. castors 7, support the whole weight of the door in stable equilibrium. The door can thus be moved across uneven ground during opening and closing, without subjecting the building structure to significant loads. <IMAGE>

Patent GB-2101829-A (GB)
Title: Radio direction-finding
Inventor: SMITH PETER WANLEY
IPC: G01S5/08
Filed: 1981-07-03
Abstract: Direction indication of one body 10 relative to another 11 e.g. between a ship and a structure, comprises determining the location of a continuously transmitting (microwave) beacon 12 on one body by a scanning receiving aerial 13 on the other. Signals received are sampled at predetermined angular intervals and each set of samples formed correlated with a stored set of reference samples, representative of the signal levels at corresponding angular intervals in the vicinity of the axis of maximum receptivity of the aerial 15 when directed at a transmitting source (measured or calculated), to determine which of the sample sets corresponds most closely to the reference sample set and thus the value of the aerial angle at which a relevant sample corresponds to the axis of maximum receptivity being directed at the beacon. The 'shape' of the received signal is preserved for correlation by an a.g.c. circuit and a reception window is also definable after the initial scans to limit reception in subsequent scans to a narrow range of angles for which the beacon direction can be predicted and modified by each measurement. The sampling and calculations may be performed in a hard wired circuit or a microprocessor. The arrangement may be used with a plurality of beacons, sending coded transmissions or modulated at different frequencies, in position marking or position indicating apparatus. <IMAGE>

Patent GB-2100171-A (GB)
Title: A power assisted tool
IPC: H02G1/00
Filed: 1981-12-09
Abstract: The power assisted tool which can be operated with one hand, includes a body (33), two mutually facing work engaging members (22, 32) a handle (27) pivotally mounted on the body (about axis 27B) and operably connected via a link (30) to member (32) so that pivotal movement of the handle in a direction toward the body causes member (32) to move toward member (22), the body housing a gas reservoir (23), a one way valve and a load responsive device. The tool is arranged so that when a reactive load between members (22, 32) exceeds a preset value during a work gripping or cutting operation, the load responsive device responds to said load to open the one- way valve to permit gas to flow from the reservoir and through passage (29B) to assist in the work operation by acting upon a piston (29) carrying the pivot (29A) connecting the link (30) with the handle. <IMAGE>
Patent GB-2092692-A (GB)
Title: Improvements in pipe joints

The recesses are formed either in the top surface of the upper flange or the under surface of the lower flange, the recesses extending radially, eg defined by the gaps between radial raised ribs on the flange. The lever (39) may be bifurcated beyond pin (41) to permit independent flexing of each brake member (40), and the lever portion behind pin (41) may be horizontally slotted so that plate (47) which contacts the release pin may flex.
