Title: Tensioning multilayer web fed through printer
IPC: B41J15/16
Filed: 1981-05-20
Abstract: A paper feed for feeding a multilayer web (1) in a printer, in which the web (1) is fed towards the printing position (4) by an input feed (5) and away from the printing position by an output feed (6). The looped web (1) between the input feed (5) and the platen (2) is subjected to frictional drag by a blade (9) pivoted about an axis (10) at a point in advance of the platen (2) to ensure that the web (1) is maintained in a taut condition during its passage past the platen (2). <IMAGE>
Patent GB-2101852-A (GB)
Title: Data transmission
Inventor: MCGREGOR ANDREW
IPC: H04L7/00
Filed: 1981-06-25
Abstract: In data transmission systems in which data is sent in binary bit streams (eg using HDLC format) and the clock at the receiver is derive from, or synchronised to, the change, eg from 0 to 1, in logic state in the incoming bit stream, the bits as they go out also go into a n bit shift register (SR) whose contents are monitored by an OR gate (01) detecting n 0 bits (eg n is between 2 and 8). When such a condition is detected, sending is delayed while a 1 bit is inserted after the nth 0 bit. At the receiver, the incoming bits go into an (n + 1) bit shift register whose contents are monitored by gating means for the combination of n 0 bits followed by a 1 bit. When this condition is detected, that 1 bit is detected. The added 1 bit, used in conjunction with HDLC code driving a phase locked loop oscillator (PLO), ensures that sync. is not lost because of a long string of 0 bits. At the receiver there is a further monitoring for (n + 1) successive 0 bits: if this is detected, an error indication is given. <IMAGE>

Title: Transmission of information in a gaming or amusement machine
Inventor: LLOYD DAVID RODERICK
IPC: G07F17/32
Filed: 1981-06-25
Abstract: A fruit machine includes a reel unit (1) with reels (4), a computing unit (2) and a payment actuator mechanism (3). The position of the reels at the end of a game is detected as an electrical signal which via a converter (5) drives a transmitting transducer (6) to emit a corresponding light signal that is conducted through a fibre optic light pipe 7 to a receiving transducer (8) of the computing unit (2). The detected reel position is evaluated by the computing unit and any resulting payment instruction is transmitted to the payment mechanism (3) as a light signal via a second light pipe (10) interconnecting a transmitting transducer (9) of the computing unit and a transducer (11) of the payment mechanism (3). <IMAGE>

Title: Fire-safe valve actuator
Inventor: BRUTON BILLY RAY
IPC: F16K31/126
Filed: 1981-07-17
Abstract: A fire-safe valve actuator cooperates with the bolted bonnet (14) of a valve to define a bolt chamber (66) with an exterior shroud (50) supporting the actuator housing (44) and provides a substantially imperfect barrier to prevent an external fire from coming into direct contact with the bolts or studs and nuts (16) that connect the bonnet to the valve body (12). The bolt chamber may also be filled with an insulation material (68). The actuator may have a return spring, connected to the actuator stem through a bearing so that the winding and unwinding of the spring (80) does not result in any substantial torque being applied to the actuator stem (30). Similarly, the diaphragm (108) in the actuator may be connected to the actuator stem by a bearing so that rotation of the stem will not impart torque to the diaphragm. Furthermore, a stop (74,76) can be provided limiting outward movement of the stem under the influence of the spring and by further providing a suitable sliding engagement between the diaphragm-actuator housing and the stem, the actuator housing (46,48, 50) and diaphragm can be readily removed from the balance of the actuator without bleeding the line pressure down. <IMAGE>

Title: Button Bit Grinding Tool Head
IPC: B24D18/00
Filed: 1981-07-31
Abstract: A button-bit-grinding-tool head (1) is made by compacting a grinding material (8) in a female mould part before the mould part is machined to form the body of the tool head (2A). A male mould part is shaped to form a part-spherical, concave grinding surface (20) with a diametral slot (21) and a third mould part, comprising a generally-cylindrical pin housed in cooperating axial bores in the male and female parts in the closed mould, forms a throughbore in the grinding element. The diametral slot does not extend through the tool body (2A) so that cooling fluid fed through the tool body throughbore (3A) into the grinding element throughbore to the diametral slot (21) is concentrated at the grinding interface. <IMAGE>

Title: Improvements in or relating to the recovery of chlorine values
IPC: C07C17/00
Filed: 1982-01-11
Abstract: In an integrated process for oxychlorination and combustion of chlorinated hydrocarbons, chlorinated hydrocarbon is burned (52) to recover chlorine values substantially as hydrogen chloride. Hydrogen chloride is recovered from the effluent (57) from the combustion by absorption (39) with aqueous hydrogen chloride. Hydrogen chloride recovered by the absorption is subsequently recovered and employed in an oxychlorination reaction (11). A gas containing hydrogen chloride, water vapour and some oxygen recovered from the oxychlorination is cooled (34) to condense aqueous hydrogen chloride (38, 48) which is employed in the absorption for recovering hydrogen chloride. The remaining gas (51) is employed in the combustion of chlorinated hydrocarbons. The process has particular applicability to an oxychlorination reaction of the type wherein a molten salt mixture containing the higher and lower valent chlorides of a multivalent metal is contacted with hydrogen chloride and oxygen to recover hydrogen chloride by enriching the higher valent metal chloride content of the molten salt mixture. <IMAGE>

Title: Integrated semiconductor device
Inventor: WILLIAMS BARRY WAYNE
IPC: H01L29/74
Filed: 1982-11-16
Abstract: The device comprises a semiconductor substrate having a thyristor section 1 and a transistor section 3 integrated therein. The thyristor section 1 includes first and second main electrodes 4 and 7 and further electrodes 5 and 6 providing a flow path for principal current between the main electrodes 4 and 7. The further electrodes include a gate region electrode 6 for initiating flow of principal current between the main electrodes 4 and 7 on turn-on and for terminating principal current flow on turn-off.

The first electrode 8 is common with the gate region electrode 3, and the second electrode 10 is electrically coupled to the second main electrode 7. The transistor section 3 is switched, when a turn-off voltage is applied to the control electrode 9, to provide a sufficiently low impedance path in parallel with the principal current path of the thyristor section 1 that the principal current flow decreases below the level necessary to maintain such current flow by regenerative action and the device turns off. <IMAGE>
