Title: Safety devices for flued gas appliances
IPC: F16K17/38
Filed: 1981-11-17
Abstract: The safety device comprises a gas control valve (2) in the gas supply line to the appliance and upstream of a gas tap (3), and a fusible plug (23) placed adjacent to an aperture communicating with the flue but not in the normal combustion product flow path of the appliance. A valve (9) is urged onto a seat (10) by a spring (16) and is attached to a diaphragm. When the gas tap (3) is closed the valve (9) is opened by gas flowing through weep passages (19 and 20) and into diaphragm chamber (13) and is held open when tap (3) is opened. If the flue becomes blocked, the combustion products are deflected over the fusible plug which will eventually melt to vent the diaphragm chamber via pipe (21) and the spring (16) will close the valve (9). Instead of weep passage (19), the control valve may have a manually operable spring loaded push rod for opening valve (9). <IMAGE>

Title: Hydraulic cylinder control
Inventor: DOLLISON WILLIAM W
IPC: F15B11/08
Filed: 1982-09-20
Abstract: The outlets of two independent fixed volume pumps 20a, 20b, are connected to the two ends of a double-acting, large rod hydraulic cylinder 10. The outlets of the two pumps are also connected, through a three-position direction control valve 40, to tank. In the neutral position, both outlets are dumped to tank. In an extension control position, the valve restricts the dump line for one pump, thereby directing its outlet to the cap end of the cylinder; and in the retract control position the valve restricts the dump line for the other pump, thereby effecting flow to the rod end of the cylinder. The fluid line between each pump outlet and its respective cylinder end includes a check valve 24. A cross-piloted sequence valve 31 is connected in each fluid line between the respective cylinder end and check valve, and responsive to the pressure of the opposite fluid line. A control method includes the steps of supplying fluid to the two cylinder ends by respective independent pumps, flowing fluid from the pump outlets to tank and selectively restricting flow to tank from one pump to effect flow from that pump to the cylinder, and controlling fluid flow from the cylinder by cross-piloted sequence valves. <IMAGE>

Title: Shadowing for radar simulator
Inventor: BERRY THOMAS ROYSTON
IPC: G09B9/54
Filed: 1982-12-13
Abstract: In a signal processor for processing a fully composed (simulated) signal of the radar type (20), means are provided for receiving signal (20) and determining a shadowing function (23) associated with an object (21) at r0 represented by the signal (20), which is blanked when the signal amplitude is less than the shadowing function. An output corresponding to the signal with blanking is provided so that an object (22) of height below the shadow function does not appear in the output. Signal (20) is blanked until its amplitude exceeds shadowing function (23) at r1. A shadowing function (24) is similarly defined to blank signal (20) between r2 and r3 to simulate shadowing by object (25). The present invention overcomes the problem with radar simulation of lack of realism in a fully composed radar scene due to lack of shadow. By determining a shadowing function based on a height difference between object (h0) and receiver (O) vertical movement may be simulated. <IMAGE>

Title: Improvements relating to digital data transmission
Inventor: CHAMBERS JOHN PHILIP
IPC: H04B17/00
Filed: 1983-01-21
Abstract: Data bits such as digital samples of a sound signal are supplemented by error checking bits. e.g. provided by a Parity Generator, and these error bits are used to carry additional data bits (Extra Data) very securely by using the additional data bits to modify groups of the parity bits by way of a Pattern Generator and Parity Modifier. The additional data may be 3-bit scale factors applying to groups of digitally companded samples. The modification is detectable and reversible and may be selective inversion of all bits in a parity bit group. At the receiving end the Data and Parity bits are conventionally treated in a Parity Checker whose output can be recognised as groups of un-modified (non-inverted) and modified (inverted) bits by a Pattern Recogniser, using majority logic so that recognition is not upset by occasional bit errors. The Pattern Recogniser thus recovers the Extra Data and enables the actual parity bits to be recovered via a Pattern Generator and Parity Check Modifier. These bits are used conventionally in relation to Corrective Action on the main Data. <IMAGE>

The polyimide-glass (13) has a higher transition temperature (260 DEG C-280 DEG C) than that of the epoxy-glass (120 DEG C) so that it suffers minimal loss of adhesion to the pads (9) at the temperature of the molten solder (220 DEG C-250 DEG C). <IMAGE>
Patent GB-842315-A (GB)
IPC: H04W88/02
Abstract: 842,315. Radio signalling. TELEFUNKEN G.m.b.H. June 21, 1956 [June 21, 1955], No. 19321/56. Class 40(5). A radio communication selective calling system comprises a main station and substations in which a substation receives call signals in a first code system and transmits call signals representing a desired connection with another station in a second code system; the main station transmits a group of tones simultaneously characterizing the substation called, the substation sequentially retransmitting tones different from the main station transmission thereby effecting the desired connection with the main station. All the tones are generated at the main station, the call signal operating resonant relays at the substation, and series resonant circuits selecting the different frequency combinations for retransmission as a call signal from the substation. At the substation the low frequency output of a known receiver is applied to terminals 1 and 2, parallel resonant relays 3-7, and series resonant circuits 8-12 separating the signal frequencies transmitted from the main. station being connected as shown, the resonant frequencies of set 3-7 and set 8-12 being in mutually non-interfering ranges. In the tapped leads of circuits 8-12 are relay contacts 13<SP>1</SP>-17<SP>1</SP> of relays 13-17 through which the transmitted signal frequencies can be applied, individually or in groups to the modulator of the transmittor by terminal 18. When a substation calls another substation, a call signal sent from the substation to the main station causes interruption of the "free" signal normally sent from the main station, which immediately transmits a modulated carrier to provide calling frequencies for the calling substations. The substation transmits a characteristic responding signal comprising a sequence of industrial frequency combinations derived from frequencies sent by the main station, and set up at the substation by stepping switches 21 appropriately connected to provide the required frequencies. In position 1 of switch 21 relays 13 and 16 operate to close contacts 13<SP>1</SP> and 16<SP>1</SP> and the two frequencies derived from circuits 8 and 11 are applied to the transmitter, each successive movement of switch 21 selecting and similarly applying two frequencies to the modulators which together all constitute characteristic code. Delay-operating relay 23 operates simultaneously with slow releasing relays 13 to 17 to produce a signal of a given length on each operation of switch 21. The main station sends a modulated signal requesting the substation to identify the station being called. The calling station dials the number operating selector 21 and through relay 22 operating in a similar manner to relay 23, a carrier modulator with successive frequency combinations is transmitted. The main station then transmits a code signal to call up the required station via its resonance relays and thereafter a speech channel is set up. Specification 838,013 is referred to.

Title: Semiconductor device and protective circuit
Inventor: IWAI HIDEOTOSHI
IPC: H01L29/792
Filed: 1984-12-21
Abstract: A semiconductor device has an internal circuit protected by an electrostatic protective circuit, the internal circuit and electrostatic protective circuit being formed on the same semiconductor substrate (20). The internal circuit includes MIS elements and has a double-diffused drain structure (29,30), while the protective circuit has a single-diffused drain structure (31,32). The internal circuit can be, e.g., a DRAM, and the protective circuit can have diffused resistors (31) and clamping MIS elements (32). The single-diffused drain structure of the protective circuit and the double-diffused drain structure of the internal circuit may be achieved by either scanning the ion implanting apparatus to avoid ion implantation into the region of the protective circuit, or forming a photoresist film over the region of the protective circuit to prevention implantation into the protective circuit region, during the formation of the first layer 29 of the double-diffused drain structure. <IMAGE>
