Patent GB-2062766-A (GB)
Title: Improvements in Hydraulic Systems
IPC: F15B1/027
Filed: 1980-10-31
Abstract: In an hydraulic system an unloader valve (23) is disposed in a supply line between a pump (1) and an hydraulic accumulator (22). The unloader valve (23) is operative to prevent the accumulator (22) from being overcharged and to allow the pump (1) to re-charge the accumulator (22) should the pressure stored therein fall below a desired minimum value. The unloader valve (23) incorporates a control valve comprising a spool (30), and a pressure responsive slave (7) which is operated by fluid pressure under the control of the control valve. The spool (30) is movable between a first position in which the accumulator (22) is isolated from the slave (7) so that pump pressure is supplied to the accumulator (22) and acts through a membrane (26) on a trapped volume of gas (27) under pressure, and a second position in which fluid pressure from the accumulator (22) acts on the slave (7) to unload the pump 1. The membrane (26) of the accumulator either acts directly on the spool (30) to control movement of the spool (30) between the two positions, or in an alternative embodiment, the membrane acts indirectly on the spool through an operating rod and an operating member. <IMAGE>

Title: Board Game
IPC: A63F3/04
Filed: 1980-11-29
Abstract: A board game comprises a board, a number of counters and two dice. The board is marked to provide a central area, representing the nucleus of an atom, and six or more annular rings extending concentrically around the central area, the rings being divided into 2, 8, 18, 32, 48 and 72 squares. Each ring represents an electron shell, and some of the squares are numbered, the number representing the atomic number of different elements. Each ring can be considered as representing both an electron shell and a row in the periodic table of elements. At least one square in each ring is marked to indicate that a piece landing on that square may proceed to a square in another ring, such as the next outer ring. The game may be in the form of a TV game. In a modification, players pass from an undivided centre space to a ring marked "3-10". <IMAGE>

Title: Magnetic Recording Layers
IPC: G11B5/712
Filed: 1981-06-08
Abstract: A magnetic recording medium comprises a substrate and a magnetic recording layer formed thereon formed of a magnetic coating material in which a magnetic powder is coated with a titanium coupling agent or is mixed with the agent and then dispersed in a binder. The binder may be prepared by mixing and plasticizing a radiation-sensitive modified resin with a radiation-sensitive soft resin and subjecting the mixture to radiation cross-linking and polymerization. To produce the medium, the magnetic particles are coated with the titanium coupling agent, the coated particles are blended with the binder, and the material is applied to the substrate. Alternatively, the titanium coupling agent is mixed with the magnetic particles, the mixture blended with the binder, and the resulting coating material applied to the substrate.

Title: A Method and Jig for Laying Bricks
IPC: E04G21/18
Filed: 1981-08-12
Abstract: This invention relates to a method of laying bricks, blocks or similar building elements, and to jigs for use in such a method.

Patent GB-2107089-A (GB)
Title: Control data transfer arrangement
Inventor: HUHN KARL-ECKARDT
IPC: H04Q11/04
Filed: 1982-08-18
Abstract: A digital exchange system having a central microprocessor (ZMP) and a plurality of decentral microprocessors. To transmit control data, input-output modules (BSD1 ... m) are connected for providing serial data transmission between the central (ZMP) and decentral microprocessors. Thus, bidirectional bus data lines (DB) and timing lines (RD, WR), likewise the bus lines, are connected between an input-output module (BSD) and a plurality of assemblies. The input-output modules (BSD1 ... m) of the central control device are directly time-controlled by the control signals of the decentral microprocessors. To buffer the data bits in the transmission direction, there is associated with each input- output module (BSD) a bistable flip- flop stage (FF), whereby operating times are compensated. For synchronisation, for selection of the type of operation and for forming a time raster, two control lines (INTV, INTS) are connected between the central control and the decentral assembly frame (BGR). A signal at the interrupt inputs of all decentral microprocessors of the assemblies of an assembly frame causes, dependent on its length, a control data exchange in the transmitting direction or transmitting and receiving directions. <IMAGE>

Title: Circuitry for reducing common mode signals
Inventor: ROBE THOMAS JOSEPH
IPC: H03F3/45
Filed: 1982-08-20
Abstract: A circuit for substantially reducing common mode signal superimposed on differential signals includes first and second resistive dividers (10, 20) having input (11, 12), output (13, 14) and common (15) terminals. The differential mode (Vdm) plus common mode (Vcm) signals are applied to the divider input terminals and also to a further circuit (40) which is selectively responsive to the common mode signal to the exclusion of the differential mode signals. An output signal from the further circuit modulates the common terminal (15) of the dividers (10,20) to cancel the common mode signals at the output terminals (13, 14) of the dividers (10, 20). <IMAGE>

Patent GB-2139021-A (GB)
Title: Inverter firing control with error compensation
Inventor: JESSEE RALPH DONALD
IPC: H02M7/5387
Filed: 1984-04-13
Abstract: A pole switch firing control for a pulse width modulated inverter controls pole switch operation under steady-state operating conditions such that the inverter output duplicates a reference signal waveform after a fixed time delay. Pole switch (10) operating time for a given pulse in an inverter output cycle is measured by counting (Z6) a sequence of clock pulses (CT) to get a count equivalent to the delay time of the pole switch (10). This count then serves as the starting point for a presettable counter (Z9) which begins to count upon the occurrence of a transition point in the reference waveform (P). When the presettable counter (Z9) reaches a preselected count, the pole switch operating cycle is initiated, thereby causing the pole switch to operate at a fixed time following a transition point in the reference signal. <IMAGE>
