Title: Gas pressure regulator
IPC: G05D16/06
Filed: 1945-09-27
Abstract: 613,429. Pressure-regulating valves. VOLCAN SOC. ANON. Sept. 27. 1945, No. 25101. Convention date, March 3. [Class 135] A gas-pressure regulator comprising a main membrane, subject on its opposite sides to the regulated pressure and to a constant fluid pressure, and connected by a lever to the valve member, has an auxiliary membrane acting on the lever and subject to the inlet pressure, for compensating for the effect on the valve member of variations in the inlet pressure. As shown, the main membrane 5, which is connected to the valve member 4 by a lever 9 pivoted at 10 and loaded by a tension spring 6, is subject on its lower face to the regulated pressure in the outlet 3, and on its upper face to the substantially constant pressure of gas within a tank 15, valved conduits 16, 18, serving for adjustment of the pressure in the tank. The auxiliary membrane 20, subject to the gas inlet pressure through a passage 21, acts, through a lever arm 22, on the lever 9 to counter the tendency of the regulated pressure to vary due to variations in the inlet pressure acting directly on the valve member. The spring 6 is connected by a short lever arm 25 to the lever 9 and is of such length that variations in the spring load, due to movement of the valve member are slight. A restriction 26 in the conduit interconnecting the membrane 5 with the tank 15 damps out oscillations of the membrane. In a modification, the pressure on the main membrane is effected by a column of liquid whose free surface, in a header tank, is of such area that defections of the membrane do not materially affect the pressure. The valve member in this construction is downstream of its seat, so that the auxiliary membrane acts on the lever 9 in the opposite sense from that in the Figure. In further modifications, the spring 6 is dispensed with and the lever 9 is positively connected to the diaphragm, e.g. by ball-and-socket fittings. According to the Specification as open to inspection under Sect. 91, the membrane may be replaced by a metallic bellows or other deformable element. This subject-matter does not appear in the Specification as accepted.

Title: Process for manufacturing oil gas
IPC: C10G9/00
Filed: 1949-09-30
Abstract: 665,720. Oil gas generation. GAS MACHINERY CO. Sept. 30, 1949 [Oct. 1, 1948], No. 26127/49. Class 55 (ii). Oil gas is generated alternately, after intervening blow periods, in each of a pair of units 10, 11, comprising fixing and combustion-vaporizing zones 12, 13 and 14, 15. Zones 14, 15 are connected, or may be developed into a single chamber, and an air inlet is provided at the gas exit end of each unit. After each unit has been heated the cycle is started by passing air down unit 10 and into zone 15 to which a fluid fuel such as petroleum oil, tar, or gas is also admitted. The heat generated by burning off carbon previously deposited in zones 12, 14 reduces the amount of fuel required; supplementary air may be supplied. Combustion products pass through zone 13 to the stack. In the make stage gas-making oil and desirably a diluent, e.g. steam are admitted to zone 15 and gases generated are fixed in zone 13 at about 1000- 1400‹ F. and discharged to a wash box. The next two stages consist of a blow and a make period with unit 10 replacing unit 11. Purges may be effected between stages; thus, blasts of air and steam may be swept through the units between the blow and make and the make and blow stages respectively. High residual carbon oils may be utilized; the temperature at the exit of the fixing zone is e.g. 100-500‹ F. lower than in normal processes. Specifications 515,996 and 665,721 are referred to.

Title: Communication system including a tone sequential receiver for  a selective call
IPC: H04L27/26
Filed: 1975-06-12
Abstract: 1461022 Selective signalling STORNO AS 12 June 1975 [12 June 1974] 25236/75 Heading G4H A communication system receiver for recognizing a call consisting of a sequence of n tone signals, each being one of a number of possible frequencies, is adapted to provide two different possibilities of continuing the correct call after each of the n tone signals (except the last), stages of a binary register each being set in accordance with which of a respective two such possibilities is used in the call received, the register thus receiving a code message combined with the call. In the Fig. 1 embodiment, the receiver is assigned 5 pairs of frequencies, each frequency being 1 of 10 possible frequencies, and the receiver can be called by any sequence of 5 frequencies the 1st ... 5th of which are chosen from the 1st ... 5th respectively of the pairs, each choice (of 1 out of 2) defining a respective bit of a 5-bit code message. Selection circuits 2, 8 initially look for the two frequencies of the first pair respectively, and if either is detected for a sufficient time (defined by a delay circuit 4), a counter 5 is advanced and a register 10 is clocked. Counter 5 causes selection circuits 2, 8 to look for the two frequencies of the second pair respectively, and register 10 stores a 1 or 0 according as the frequency (of the first pair) was detected by selection circuit 8 or not. Operation continues similarly, and if and when all 5 frequencies have been received, counter 5 enables display 12 to display the 5-bit message in register 10. In a modification (Fig. 2, not shown), the receiver is called by a unique sequence of 5 frequencies, each being 1 of 10 possible frequencies, and after each frequency an 11th possible frequency is inserted or not (depending on the value of a corresponding bit of the code message to be sent) prior to the next frequency in the sequence of 5, the latter following the previous frequency in this sequence immediately if the 11th frequency is not inserted. The selection circuit corresponding to 8 in Fig. 1 is just for detecting this 11th frequency, so the connections from 6 to it and from 9 to 4 in Fig. 1 are omitted.

Title: Pressure loaded rollers
IPC: B65H20/02
Filed: 1975-05-21
Abstract: 1507984 Feeding webs COIL MACHINERY (COMAC) Ltd 21 May 1975 [6 June 1974] 25269/74 Heading B8R [Also in Divisions B3 and B4] A pinch roller assembly includes an upper roll 12, a lever 20 connected to the roll at 22 for moving it towards and away from a lower roll 10, force-applying means, such as a spring 24, at a region 26 of one lever remote from the connection 22, and two fulcra 32 and 38 either of which can be brought into operative association with the lever at will, the lever urging the roll 12 towards the roll 10 when the fulcrum 32 is operative but not when the fulcrum 38 is. The fulcrum 32, in the form of an eccentric, is made inoperative, for the introduction of strip to be fed, by rotating it anticlockwise to allow the levers to pivot about connection 22 under the action of the spring 24. This brings the lever to bear on the pin which constitutes the fulcrum 38, the spring 24 tending then to lift the roll 12. The height of the pin 38 is adjustable by means of an eccentric mounting 40 to vary the roll gap when the fulcrum 38 is operative. The eccentric 32 can be brought into operation mechanically, e.g. by linkage between the eccentric and a moving part of a press or guillotine to which the strip is being fed, to determine the length of feed stroke. The roll assembly may also be used in strip uncoiling or levelling machines. In a strip leveller, Fig. 3, an entry and an exit assembly, 46, 48, respectively, have their lower rolls driven by belt drive (72), Fig. 4 (not shown) via pinions 52 which also drive the con-   ventional leveller rolls. Each assembly includes a lever 20 at each side of the strip line, each lever being forked at 37 with its eccentric 32 acting between the limbs of the fork. Both eccentrics 32 and pins 38 of an assembly are mounted on common spindles 34 and 42 respectively. A set screw 67 above each pin is used to take up unwanted initial clearance. In alternative embodiments, the pin(s) 38 is/are fixed and the pivot(s) 22 include an eccentric. The spring 24 may be replaced by a pneumatic cylinder and the eccentrics 32 and 40 may be moved by pneumatic pressure.
