Patent GB-2083148-A (GB)
Title: Trailer relay valve
IPC: B60T15/42
Filed: 1981-09-04
Abstract: A relay valve provides an initial pressure advance in a trailer brake with minimal hysteresis, the advance being adjustable. A retroactive piston (12) is subjected to the pressure introduced by way of a triple valve (17, 30, 31) operated by the control piston (8). The pistons (12, 8) have approximately the same external diameters. An adjustable stop (29) provided in the control piston (8) is initially ineffective so that the control piston (8) responds rapidly so as to change over the control valve in the braking sense, and thereby provide the initial advance. However, after a predetermined pressure has been exceeded in output chamber (14), the retroactive piston (12) moves to abut the adjustable stop (29), whereupon the advance in the braking of the trailer is terminated and the valve thereafter operates conventionally with small hysteresis. <IMAGE>

Title: Inertia motor
Inventor: ETANIYOHWO AGOFURE ANTHONY
IPC: F03G3/00
Filed: 1981-12-07
Abstract: An inertia motor which transforms rotating energy potential into a steady unidirectional energy potential that can be used directly for translational, propulsive or static applications consists basically of a system of masses constrained to rotate about a fixed point such that their resultant centre of mass remains displaced in a fixed position and direction relative to the centre of input rotation at all times. These conditions are satisfied by a multiple arrangement of co-planar slider-crank mechanisms disposed at regular angular intervals of 2 pi /N radians where n = the number of masses each of which is carried at the slider end of a connecting rod. <IMAGE>

Title: Electrically conductive container
Inventor: BROOKS PATRICK
IPC: H05F3/02
Filed: 1982-07-08
Abstract: In an electrically conductive container for powdered or granular materials a major part of the surface is electrically interconnected to ensure that the resistivity between that part and an electrically conductive and earthable member is below a safe value, i.e. 10<7> ohms, thereby minimising the risk of dust explosion due to static electricity. This is achieved by using electrically conducting thread in forming the container from the sheet material or the woven fabric which embodies electrically conductive yarns, and/or by utilising strips of electrically conductive material secured into the container.

Title: Delivery apparatus for delivery of bales of pressed material
Inventor: LANGE HERMANN
IPC: A01D87/12

Patent GB-2277231-A (GB)
Title: Frequency hopping radio communications
Inventor: MUNDAY PETER JACQUES
IPC: H04B1/713
Filed: 1984-05-12
Abstract: The system has a plurality of radios each incorporating a transmitter 12 and a receiver 18. When a radio is not transmitting or receiving, a switch 22 switches it into a mode in which it monitors the signal strength in each of the available hop channels so as to assess the level of interference, and selects a subset of the total number of channels, those having the lowest interference level. The identities of this subset of channels are stored in a store 74. When the radio is to transmit a message, it first transmits the identities of the subset of channels stored in the store 74 - using the full number of hop channels (the information being transmitted with sufficient redundancy to overcome likely interference). The receiving radios receive the identities of the subset of channels. The transmitting radio then transmits, pseudo-randomly, on this subset only and each of the receivers receives on this subset only. In this way, transmission and reception takes place only on the channels where the interference is low. <IMAGE>

Title: Manufacture of extrusion dies
Inventor: FELDCAMP EDWARD GEORGE
IPC: B23H9/00
Filed: 1984-07-16
Abstract: A method of manufacturing an extrusion die includes the production of a graphite electrode 8 which corresponds to the geometry of the die cavity plus an all round clearance, and spark erosion of a die blank 5 using the graphite electrode to produce a back clearance 7 which provides the determined maximum bearing length t for the cavity. The die cavity is spark eroded from an initial hole 6a employing a wire cutting technique with the blank 5 in a hardened state. After profiling the end face of the graphite electrode 8 so that it conforms to a determined required overall bearing contour, it is re-introduced to spark erode the back clearance and thus to produce substantially the correct bearing form for the die. To reprofile the electrode, an initial test extrusion is taken, the electrode profile being complementary thereto; alternatively a computer-controlled milling machine is used. <IMAGE>
