Title: Storage of liquefied normally gaseous material
IPC: F25J1/02
Filed: 1946-03-21
Abstract: 609,701. Refrigerating. TRIGGS, W. W. (Specialties Development Corporation). March 21, 1946, No. 8747. [Class 29] [Also in Group XXVIII] Solid carbon dioxide or other normally gaseous material is placed in a storage container 110 and liquified by a coil 17 operating as the condenser of a reversible refrigerating system, the system is then reversed so that the coil acts as an evaporator and maintains the carbon dioxide liquid during storage. The container is double-walled with a vacuum space 122 between and is accessible through a pressure-tight cover 128 and insulating cap 152. A discharge pipe 168 for the liquid carbon dioxide passes through the two walls and is provided with a closure valve 174. The coil 17 comprises a single turn 178 in the upper part of the container connected to a helical coil 188 at the bottom of the container protected from damage by impact with the charge of solid carbon dioxide by a cylindrical shield 194. For melting the solid carbon dioxide hot compressed refrigerant vapour passes from the compressor 28 through valve 6 and conduit 46 to the coil 17 where the refrigerant is condensed and passes through valves 1, 2 to a liquid receiver 22 and thence through a dehydrator 23, valve 3 and expansion valve 24 to coils 26 acting as an evaporator cooling air supplied by a fan 27. From the evaporator the gaseous refrigerant passes through a valve 10 to the suction side of the compressor 28. To maintain the temperature of the cold refrigerant above a predetermined minimum and prevent damage to the compressor and frosting of the coil 26, valves 12, 14, 15 are opened and valve 1 closed, so that the refrigerant passes through heat exchangers 18, 19 and is heated by the hot gases. If less heating of the refrigerant is required one heat exchanger 19 is cut out by closing valves 14, 15. When the carbon dioxide is melted the system is reversed by manual or automatic operation of the various valves and hot compressed refrigerant vapour from the compressor passes through valve 5 and conduit 42 to the coils 26 now acting as a condenser. The liquid refrigerant passes through conduit 52 and valve 9 to the liquid receiver 22 and thence through pipe 62 and expansion valve 20 to the lower end of the coil 17 which thus acts as an evaporator. From the upper end of the coil 17 the refrigerant returns by the pipe 46 and a valve 11 to the suction side of the compressor. The expansion valves 20, 24 are of the fixed restriction type and the cooling is automatically controlled by a switch actuated by a pressure responsive device, connected to the container 114 near its discharge end, to stop and start the compressor 28 and fan 27. Modified circuits are described in which the expansion valves are controlled thermostatically, the heat exchange units 18, 19 being omitted, and in which the refrigerant always flows in the same direction through the coil 17.

Abstract: 1,039,544. Perforating. GARRETT CORPORATION. March 5, 1963 [March 7, 1962], No. 8767/63. Headings B3A and B3W. [Also in Divisions E1 and F2] A method of producing in a metal sheet having projection free surfaces, perforations having a width less than the thickness of the sheet, oomprises the steps of making cuts round portions of the sheet and displacing them out of the plane of the sheet, removing a predetermined amount of the exposed edges of each cut, and restoring the portions to the plane of the sheet. To form U-shaped slots, tabs are stamped and bent out, the cut edges or the whole sheet chemically etched (Figs. 1-4, not shown) while to produce straight slots the sheet is sheared and bent to form rows of staggered corrugations (Fig. 5, not shown) prior to etching, the sheet being rolled, pressed, or hammered after etching to flatten it again. A resistant coating may be applied to the sheet prior to the first step, to restrict etching to the cut edges.

[Also in Group XXVIII] In a revolving cylinder motor, the pistons co-operate with a swash-plate 16 and the cylinder block is supported by a thrust bearing 24 in a stirrup member 23 that is pivoted on trunnion members 21, 22 and is adjustable to vary the stroke of the motor. A cylindrical stationary valve member 28 has slots 45, 46 cooperating with the cylinder ports and is supported by a thrust member 65 carried by the stirrup member. The slot 46 communicates with the inside of the casing 17 whilst the slot 45 communicates through a passage 48 in an arm 49 with a passage 55 in a connector 51 that is slidable in a socket 50 in the arm 49 and has packing rings 52, 53. The connector 51 is connected by a flexible hose 56 with a similar connector 58 in the trunnion 21 that has a liquid passage 60. In a modification shown in Fig. 4, a cylinder head 75 is secured to the cylinder block 27 and has passages 76 communicating with the cylinder spaces. A distance piece 81 is clamped by a bolt 83 between a bridge member 82 and the cylinder head 75 so that a guide is formed for an annular valve 86 which is arranged eccentrically to the ring of ports 76. To provide resilience to the land 98, a deep groove 93 is provided from a shallow groove 96 which is fitted with a non-metallic ring 95 and a metal ring 97 so that pressure liquid can act on a small area and force the land against the bridge member 82. The valve acts as a reversing valve by varying its eccentricity and has stems 87, 88 guided in cylinders 89, 90 in the stirrup member. The stem 87 has a bore leading to a liquid passage 91 in the valve and the stem 88 is solid and can be supplied with fluid pressure to move the valve. In a modification, the valve is pivoted so that it can move to vary its eccentricity to the ports 76.

Attenuators. An attenuator comprises three condensers Ca, Cb, Cc, having their movable plates mounted on the same shaft S, Fig. 2, and so shaped as to produce a prescribed relation between image impedances, attenuation, and angular position of the shaft. The Specification describes in detail how to shape the plates in order that the image impedances may be constant while the attenuation varies linearly as the shaft S is rotated. In a modification, Figs. 3, 3a (not shown), the three movable plates may be replaced by two plates which work between fixed plates suitably arranged and shaped, or by an equivalent thick plate. Alternatively, the condensers may be connected to form a pi section, Fig. 4 (not shown), and one of the movable plates must then be insulated from the other two, Fig. 5 (not shown), or the three capacities may comprise the capacity between two fixed plates together with the capacities between each fixed plate and a rotatable thick plate or a pair of plates.

In gain-control circuits for amplifiers for use in wired wireless systems, of the type in which a negative feed-back circuit includes a distortion - compensating network N, Fig. 11, as described in Specification 371,887, [Group XLJ, variations in the line attenuation due to weather conditions are compensated by means of the attenuator described above, Fig. 1. The attenuator may be controlled manually or by a pilot-wire system 36. The condensers Ca, Cc form a potentiometer so as to minimize phase-shift, while the condenser Cb, compensates either for errors due to the introduction of this potentiometer or for the error due to the impedance, including inherent capacity of the grid circuit of the valve 31. Alternatively, Fig. 12 (not shown), the condenser potentiometer Ca, Cc may be connected between the points 4, 5 instead of the points 5, 6, in which case it reduces the attenuation due to the network N to any desired fraction, thus providing fine adjustment. The network N may then simulate the difference between the two extremes between which the attenuation characteristic of the line varies with weather conditions.

IPC: F16H27/06

Abstract: 1,032,112. Intermittent toothed gearing. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. March 5, 1963 [March 13, 1962], No. 9616/62. Heading F2Q. [Also in Division H2] In a mechanism providing rapid intermittent rotation of a Geneva star-wheel 2, particularly for rotation of a transformer tap changer, a roller 15 driving the star-wheel is carried by an operating member 3 which is driven, as by a geared-down electric motor 8, through a first lost-motion coupling comprising a driving arm 33 and driven arms 31, 32, a shaft 4 coaxially arranged within the member 3, and a second lost-motion coupling comprising a crank arm 5 of the shaft 4 and shoulders 21, 22 on the member 3, and a spring assembly connected to the crank arm 5 provides a snap-action drive which overruns that of the motor 8 and rapidly rotates the operating member only during its star-wheel rotating movement. The star-wheel 2 comprises slots 16 to receive the roller 15 and locking recesses to engage an operating member cylindrical portion 19 having the usual cut-away 17. The spring assembly comprises a pivoted cylinder 13, a piston 25 having a rod 12 pivoted on a pin 11 of the crank arm 5, and a spring 14 between the piston 25 and a collar 26 which has free movement on the rod limited by a rod abutment 27 so that the spring is pre-stressed. A hole 28 is bored in the cylinder so that when the latter is immersed in oil the piston and cylinder act as a dashpot. From top dead centre of the crank pin 11 (Fig. 2) the piston-rod movement is initially free until the collar 26 abuts the bottom end of the cylinder. The spring is then compressed until the pin 11 reaches bottom dead centre after which the spring expands and rapidly upwardly returns the crank pin. The second lost-motion coupling enables the mechanism to be used in either direction of rotation. In operation, from the starting position shown, as the motor 8 rotates, say in an anticlockwise direction, the arm 33 abuts the arm 31 to rotate the shaft 4. The rod 12 moves out of the cylinder and eventually the crank arm 5 abuts the shoulder 21 to rotate the operating member 3. The driving roller 15 enters a slot 16 at bottom dead centre of the pin 11 and spring expansion causes rapid rotation of the operating member 3 and the star wheel 2, overrun of the motor being permitted by the first lost motion coupling 33, 31, 32. Immediately the roller 15 emerges from the slot 16 the abutment 27 engages the collar 26 so that no further movement is provided by the spring and the arms 33, 32 abut at this instant. No further rotation of the operating member occurs until the arm 33 catches up with the arm 31 at completion of the cycle. The main drive by the motor 8 ensures full rotation of the star-wheel 2 in the event of spring drive failure.
