Patent GB-2072528-A (GB)
Title: Air filter
IPC: B01D46/04
Filed: 1981-03-13
Abstract: A filter for filtering air has a dirty air inlet chamber (2) and a dust collection chamber (5). A number of filter tubes (4) extend vertically between the chambers. The bags are connected at their ends to portions of the walls of the chambers. One of the wall portions (7) is resiliently connected to the rest of its chamber by a rubber mounting, extending around the periphery of the wall portion to form an effective air-tight seal. An electromagnet and attraction bar arrangement serves to vibrate the resiliently mounted wall portion to shake the tubes free of accumulated dust. Either the magnet or the bar is secured to the wall portion while the other is secured to a fixed part of the filter. The magnetic field produced by the magnet is alternately created and collapsed by supplying the coil of the magnet with a half-wave rectified current. Chamber (5) has a dust-collecting drawer or a dust discharge valve. <IMAGE>

Title: Current mirror circuit having high output impedance and low loss
IPC: H03F3/347
Filed: 1981-05-12
Abstract: A transistor current mirror circuit suitable to be integrated comprises a main current mirror A, a secondary current mirror B and circuit means for comparing and amplifying current. The input current IS of the main current mirror is mirrored into a plurality of output branches and a user may be connected to each of these branches. The input of the secondary current mirror circuit B is connected to one output branch and feeds back the out- put current IC of the main current mirror to the input of the circuit means for comparing and amplifying current, which also receives the input current Ii to be mirrored. This circuit means is therefore an "error amplifier" of the error current Ii-IC which is amplified and supplied to the input of the main mirror. Opposite variations of the amplified current correspond to variations of the output current IC and therefore compensate it. The mirror circuit thus has a high output impedance and a small voltage loss. <IMAGE>

Patent GB-2106752-A (GB)
Title: Concentrator
Inventor: SCARR ROBERT WALTER ALISTER
IPC: H04Q3/545
Filed: 1981-09-22
Abstract: In a telephone exchange the line circuits each of which is the interface between a subscribers' line and the exchange, are relatively complex and expensive units. Hence it would be useful to be able to reduce the number of such units needed. To do this a block of lines incoming to the exchange are connected to the nets of a plural-stage co-ordinate switching assembly (1), known as a pre-concentrator. The outlets from this assembly (1) give access to a number of line circuits (LCl, LCq), which are much less in number than the lines. Lines are scanned by scanners (3), which are modular in rating which scanners detect calling conditions, and cause, via a control unit (4), connections to be set up from calling lines to the line circuits (LCi, etc.). These give access to the main switch (2) of the exchange. For relatively low traffic lines, 64 line circuits may be provided for each block of 1000 lines, while for heavy traffic lines a block of 1000 lines may need 432 line circuits. With cheap cross-point devices a net economy results in spite of the need to place line protection elements and possibly also DC power feed on the line side of the switching assembly.

Title: Digital data encoding
Inventor: JOHNSON KENNETH CHARLES
IPC: H04L25/49
Filed: 1983-02-21
Abstract: An encoder circuit divides each sequence of binary zeroes into pairs with one unpaired bit encoded as a pulse in the first half of the clock period, and each pair is encoded as a pulse in the second half of the clock period. This ensures that the minimum spacing between adjacent pulses is 11 DIVIDED 2 clock periods.The signal is decoded by stretching each received pulse to a length equal to 11 DIVIDED 2 clock periods and sampling the stretched pulses with a clock signal. Stretching pulses representing an unpaired bit are sampled once, while those representing a pair of bits are sampled twice. A synchronised receiver clock is generated from a known pattern of three zero's which produces the pulse pattern 23, pulse 21 being a single zero in the first half of the clock period. <IMAGE>

Title: Connecting implements to tractor lift linkages
Inventor: WRIGHT PHILIP P J
IPC: A01B61/02
Filed: 1984-03-07
Abstract: Interconnecting means for interconnecting the top hitch point of a towed agricultural implement to the top hitch point of a three point linkage of a towing vehicle is provided in which a collapsible linkage (30) is restrained against collapse by a shear pin interconnecting two relatively slidable linkage portions (31, 36). The uncollapsed position of the linkage is defined by abutment portions (33, 40) on each of the two linkage portions (31, 36) and suitably one (40) is adjustable so that the length of the linkage may be varied. The shear pin is arranged to fail on encountering a load in excess of a predetermined load which causes initial collapse of the linkage. On collapse the towed implement is allowed to pivot upwards about the lower hitch points so as to clear an obstruction whereupon a tensile load is automatically imposed upon the linkage causing the two linkage portions (31, 36) to return to their predefined positions thereby permitting a new shear pin to be positioned between the two portions. <IMAGE>
