Title: Underground storage of liquefied gases
IPC: F17C3/00
Filed: 1959-03-24
Abstract: 851,094. Storing liquefied gases. DIMENTBERG, M. March 24, 1959, No. 10147/59. Class 8(2). Underground storage of light hydrocarbon gases e.g. natural gas is effected by liquefying the gas in a known apparatus 2 forcing the liquid by a pump 16 through a valved duct 3 into a cavern 1 thereby freezing the interstitial water in the cavern walls thus rendering them impermeable, and using inflowing ambient heat to revaporize the liquid which is withdrawn by a pump 21 up a duct 4 leading to an outlet service duct. Excess vapour pressure is relieved through valves 11, 12 back to the refrigerator 2. Liquefied gas may also be pumped through a line 19 and flashed at a valve 20 into the cavern thus effecting a quicker reduction in temperature of the stored liquid.

Title: Rivet setting tool
IPC: B25B27/00
Filed: 1942-07-21
Abstract: 555,713. Riveting. CHICAGO PNEUMATIC TOOL CO. July 21, 1942, No. 10176. Convention date, Dec. 30, 1941. [Class 43] In an automatic tool for setting rivets of the kind having an internal screwthread at the end of the shank, driven and driving shafts are provided with two connections, the first causing rotation of the driven shaft with the driving shaft and relative axial movement, and the second permitting free rotation of the driven shaft at first and later preventing such rotation. A sleeve 13 is driven by an electric or other reversible motor. The sleeve is internally threaded to engage a driven shaft 13, a spring 17 providing friction at the screw-threads. A bit 21 is constrained by a ball 22, held in place by a sleeve 25, the rotate with the driven shaft, the bit being threaded to engage the internal thread of the rivet 31. The bit rotates with ,but can slide longitudinally through, an anvil 34 co-operating with a friction ring 41. The bit is introduced into the rivet and rotates freely until the anvil 24 contacts with the head of the rivet. Further relative rotation causes the ring 41 to retard the rotation of the anvil, with the result that the sleeve 13 draws the driven shaft 16 upwardly, and a ball 47 rises and engages one of a number of grooves 46, stopping the rotation of the driven shaft. Consequent axial movement of the bit expands the central part of the rivet to grip the work. When this expansion is complete rotation of the sleeve 13 ceases on account of the resistance to rotation causing a clutch, not shown, to slip. The direction of rotation of the sleeve 13 is then reversed and the tool is disengaged.

Title: Improvements in heat exchangers particularly fuel oil heaters
IPC: F28D7/12
Filed: 1943-06-24
Abstract: 570,491. Heat-exchangers. FOSTER WHEELER, Ltd., and HUMPHREY, K. E. June 24, 1.943, No, 10190. [Class 64 (iii)] In a heat exchanger such as an oil heater which comprises inner and outer elongated shells or cylinders 1, 6 at the one end of the inner of which the heating agent, such as steam. is admitted and released, liquid to be heated flowing through the space between the inner and outer shells which are withdrawable one from the other longitudinally for cleaning, the annular space between the shells or cylinders is divided into semi-annular passages through which the liquid to be heated flows in series back and forth from the inlet to the outlet. The annular space between the cylinders is divided by two longitudinal partitions each composed of a channel 11 on one cylinder into which engages a strip 12 of triangular cross-section on the other cylinder. The inner cylinder is formed with a head 7, which closes the corresponding end of the outer cylinder and has passages 8, 10 through which steam is supplied to and the condensate discharged from the inner cylinder. In another form, U-shaped passages in the head communicate with inlet and outlet passages formed in projecting portions of the walls of the outer cylinder 1, and the inner cylinder and its head can be withdrawn without disturbing the steam and condensate piping. The head is clamped in place by a screw in a bridge piece which engages in the ends of two arms pivoted one on each side of the outer cylinder. The inner cylinder may be finned. A partition of cruciform crosssection may be fitted in the inner cylinder when a liquid heating agent is used. The outer shell may have a spring-loaded relief valve and the inner may have means for releasing air. Heat exchangers may be arranged in groups with cocks and by-passes so that any one may be isolated for inspection and clearing.

Title: Variable resistance circuit
IPC: H03G1/00
Filed: 1969-02-26
Abstract: 1,261,737. Transistor circuits. NIPPON ELECTRIC CO. Ltd. 26 Feb., 1969 [29 Feb., 1968], No. 10233/69. Heading H3T. A circuit (inside dotted lines) having a variable resistance to A.C. and a substantially constant resistance to D.C. between TL1 and earth, has two transistors TR1, TR2 with their collectoremitter paths in parallel and a common emitter resistor R5, one transistor TR2 operating in grounded base to A.C. and receiving a reference voltage from for example R3, R4; and the other transistor TR1 receiving a control voltage at TL2, and having a base circuit impedance high enough compared with its emitter-base impedance to render its collector-emitter path A.C. resistance dependent upon the signal at TL2. The capacitor C2 puts TR2 in grounded base for A.C., and C1 renders TR1 grounded emitter. The gounded base transistor TR2 has a relatively large and substantially constant output resistance (c-e) to A.C., and as that of the grounded emitter transistor TR1 varies with its collector current, the A.C. resistance of the parallel combination is variable by changing the balance of currents in the two transistors TR1, TR2 by adjusting the D.C. control level at TL2. As the sum of the collector currents is unchanged, the transistors acting as a long tailed pair, the D.C. resistance is unchanged. The A.C. gain of an amplifier transistor TR4 is thus variable without varying its D.C. bias levels. In another embodiment (Fig. 3, not shown) an amplifier transistor TR5 has its A.C. gain varied by connecting the variable (A.C.) resistance circuit TR1, TR2 between its collector and base, the reference voltage to TR2 coming from a potential divider R3, R4, and the control input going to TL2 as before. In this case C2 is arranged to put TR1 in grounded base mode for A.C. More transistors may be added with their collector-emitter paths in parallel with TR1 and TR2, and with their bases connected to either of the base circuits of TR1, TR2 or to other inputs. The resistor R4 of the variable resistance circuit may be replaced by a Zener diode, the A.C. impedance of which may be low enough to enable C2 to be dispensed with.

Abstract: 554,113. Treating ferrous articles. HYDROBLAST CORPORATION. July 24, 1942, No. 10402. Convention date, July 25, 1941. [Class 60] In order to. prevent rusting of ferrous articles after being treated by a wet sand blasting process such as that described in Specification 498,478, a corrosion inhibiting chemical such as potassium dichromate is dissolved in water to form a saturated solution and is then pumped into the water supply line of the sand-blasting gun, the mixture of water and inhibiting fluid being heated to body temperature before passing to a high pressure pump and to the gun to which the abrasive particles are also supplied. As shown in Figs. 1 and 2, potassium dichromate crystals are placed in a metal perforated basket 16 immersed in a water tank 10 in which water is maintained at a constant level and at a uniform temperature by cold water circulating through a coil 20, The solution is maintained in an agitated condition by a pump 30 connected to the tank 10 by flow and return pipes 34, 42. The solution is supplied to the water supply pipe 52 of the sand-blasting gun 74 by a pipe 46 under the control of a needle valve 44. The solution mixed with water is passed through a heater 64 and to a high-pressure pump 62 and thence through a pipe 76 to the gun 74 supplied with sand from a tank 80. In an alternative arrangement (not shown) the water in the pipe line 52 is passed through the heater 64 before the corrosion inhibiting solution is mixed with it. In a more simplified form of plant (not shown) the cooling coil 20 is dispensed with and a by-pass pipe is arranged between the outlet and inlet of the pump 30 which does not recirculate the solution in the tank 10.
