Abstract: 728,423. Storing liquefied gases; securing pipes in casings. UNION CARBIDE & CARBON CORPORATION. July 17, 1953 [Sept. 12, 1952], No. 19926/53. Classes 8 (2) and 99 (1). In a container for storing liquefied gases below 275‹K. comprising an inner vessel A, Fig. 1, and an outer shell B spaced by heat insulating material 10, the inner vessel A has a vertical side wall 11 of prestressed reinforced concrete maintained in a state of compression when in contact with liquefied gas by tension members e.g., steel wires 12, 13 encircling the wall. The vessel cover 14 is of concrete reinforced by a metal screen 14<SP>1</SP> (not shown) and prestressed by wires 11<SP>1</SP>, and the wall rests on a reinforced concrete footing ring 15 supported by layers of foamed glass, a concrete slab 17, a layer 18 of sand, and earth 19 maintained above freezing point by heater tubes 29. The vessel floor 20 is of concrete containing entrained air .and supports a steel liner 21 welded to an upstanding flange 23 carrying at its upper rim a steel bar 24 embedded in the wall 11. The flange 23 may be of steel, copper, copper alloy, aluminium or aluminium alloy of high impact strength at low temperatures. The shell cover 26 is of concrete and the outer shell wall 25 which is of prestressed reinforced concrete extends below ground level to rest on a foundation 27. A vapour outlet duct includes an'expansion joint 40 within the insulation 10 and connecting pipes 38 each of which passes through a steel sleeve 51, Fig. 6, lining coaxial apertures in the covers 14, 26; the ducts 38 being welded to the sleeves 51 by conical steel frustra 52.

Title: Improvements in or relating to means for releasably holding tanks or other objects on aircraft
IPC: B64D37/12
Filed: 1943-11-29
Abstract: 575,165. Dropping articles from aircraft. HAWKER AIRCRAFT, Ltd., HOLLYHOCK, W. S., and WHALE, S. H. Nov. 29, 1943, No. 19931. [Class 9 (ii)] [Also in Group XXV] Relates to structures for releasably holding objects, particularly auxiliary fuel tanks, on aircraft, in which a pivoted hook is held in the engaging position by a latch, a trip lever so co-operating with the hook and latch that the hook is disengaged from the object, after being freed from the latch. According to the invention, the trip lever is pivoted on the hook, and after freeing the hook from the latch is adapted to move the hook positively into the disengaged position. In the engaged position, Fig. 3, the hook 6, pivoted at 3 between side walls 2 of a housing, grips the object against the upper part 8 of the slots 5 in the walls 2. The trip lever 10 has two V-shaped arms and is pivotally mounted 'on the hook at 9. A latch 15 consists of two levers pivoted at 16 and also joined together by a spindle 17. To release the object, the trip lever 10 is turned by a handle 14, Fig. 2, so that the upper parts of its arms pass under the spindle 17 and release catch pins 7, on the hook, from notches 18 in the latch. Further movement of the handle 14 turns the hook in an anti-clockwise direction, releasing the object and forcing it down the slots 5 by the ramps 21. Springs 11 are provided to prevent accidental release. An indicator arm 20 is visible below the housing when the hook is in the engaged position.

Title: Improvements in or connected with paper bag making machines
IPC: B31B19/74
Filed: 1920-07-09
Abstract: 170,085. Collis, A. July 9, 1920. Paper bags, making.-Relates to machines for making paper bags from continuous tubular blanks, and consists in providing change-speed gears between the driving-motor and the drying- cylinder, and between the cutters and the drawrolls, &c. in order that the size of the bags made by the machine can be quickly and easily changed. As shown in plan in Fig. 1, the drying-cylinder is driven by a motor C through a change-speed gear A, and the gear is connected by a shaft H and universal joints with a clutch F which is in gear with the cutter E'. The draw-rolls, gummers, &c. of the bag-making mechanism are driven from the cutter through a bevel-wheel P and a change-speed gear I. By altering the gears I and A, the relation between the speeds of the cutter and the draw-rolls can be altered, and therefore the size of the bags made by the machine, the rotation of the drying-roll being altered accordingly to preserve the spacing of the bags. The rod H is made removable and telescopic to permit the addition of printing-mechanism.

Title: An improved generator of synchronising impulses for television and the like
IPC: H04N5/06
Filed: 1936-07-28
Abstract: 466,930. Television. RADIOAKT.-GES. D. S. LOEWE. July 28, 1936, No. 20885. Convention date, July 29, 1935. [Classes 40 (iii) and 40 (v)] Frequencies, which are integral multiples of the desired frequencies, control the production of two groups of synchronizing signals of different frequency by two generators Tx, Ty, each of which has its own current supply Nx, Ny and is connected to a screening-grid or five-electrode amplifying-valve 19x, 19y which is free of reaction. The generators, which are of the type described in Specification 459,602, pass positive impulses to the amplifier through a grid-current limiting resistance 22x, 22y. The discharge of the generating-circuit takes longer than a period of the controlling frequency and a potentiometer 26 adjusts the amplitude of the controlling- frequency and thus the frequency of the impulses. A part of the controlling-potential of the generator Tx of higher frequency is superposed on the controlling-potential of the lower-frequency generator Ty by a coupling 33, 34, which may be disconnected at 35, and the low-frequency controlling potential is freed from harmonics by a low-pass filter 30, 31. For interlaced scanning a first harmonic of the line frequency is passed through this coupling to control the image-change frequency. A resistance 36 keeps the line frequency from the coupling. Specification 423,394 also is referred to.
