Title: Method and apparatus for transporting liquified gas
IPC: F17C9/02
Filed: 1937-01-14
Abstract: 488,375. Storing and revaporizing liquefied gases. LINDE AIR PRODUCTS CO. Jan. 14, 1937, No. 1106. Convention date, Feb. 18, 1936. [Class 8 (ii)] Liquefied gas is conveyed in a closed insulated container in a subcooled condition so that it does not reach the boiling point under influence of heat leakage during the journey; a part is delivered from the container, evaporated, and the vapour discharged to receiving vessels. Fig. 1 shows a storage tank comprising main and auxiliary vessels 21, 22 surrounded by insulation through which nitrogen gas passes by a pipe 151 from a column 10 which also supplies liquid oxygen to the vessel 22 by a pipe 16. The gas spaces of the vessels 21, 22 are joined by a conduit 27, and liquid is delivered by gravity through a valve 25. Momentary pressure increase in the vessel 21 is attained by delivering a portion of the liquid to a conduit 30 exposed to air and connected to the gas space. Gas is drawn off from the vessel 22 and the liquid thus subcooled either by a fan 32 which conveys the gas through a pipe 36 to a low-pressure storage vessel, or to an injector 19 leading from the lower to the upper section of the oxygen column 10, or by a reciprocating pump 38 delivering the gas after preheating and mechanical and /or chemical separation of lubricating water &c. to storage vessels 46. The vessel 21 supplies liquid oxygen to a transport vessel 48 having an atmospheric heating coil 58 and an exhauster 63 and conduit 65 leading to the gas conduit 27 and the exhauster 32 ; a gas byepass is provided for the exhauster 63, and a liquid discharge leading to a coupling 60. In filling, the vessel 48 is exhausted of gas which is delivered to the gas space of the vessel 21 until this pressure is sufficient to expel the liquid therefrom, excess gas being then passed to the exhauster 32 or pump 38. Subcooling of the liquid in vessel 48 may be effected during delivery by throttling the liquid through valve 52 in the discharge pipe and drawing gas off by the exhauster. Fig. 2 shows a portable vaporizer coupled to the transport vessel 48, and comprising a vessel 78 the residual gas in which operates an injector 90 to fill the vessel with liquid which is afterwards vaporized in a coil 81 the gas passing to storage vessels 86 ; an injector 103 operated by gas from the vaporizing coil draws gas from the vessel 48. In a modification, a pair of vessels 78 is used. In a further modification, a rotary pump delivers the liquid from vessel 48 to injector 90, and a surge chamber is connected with the injector. In further modifications, a warm converter as described in Specification 287,909, [Class 8 (ii)], is employed or a pump as described in Specification 342,423 delivers liquid to the vaporizing coil. Specification 456,209 also is referred to.

Title: Improvements in apparatus for feeding or conveying cement to mixing apparatus and for like purposes
IPC: B65G53/46
Filed: 1939-01-13
Abstract: 523,722. Pneumatic conveyers ; shoots. CASSIERE, A. T. Jan. 13, 1939, No. 1149. [Class 78 (i)] A device for conveying cement or other material from a hopper 2 comprises a spherical rotary member 4 arranged in a housing 1 at the base of the hopper and having elongated peripheral pockets 6. The rotary member projects into an air conduit 7 and is arranged with its axis 5 parallel thereto so that the air pushes the material out of each pocket in turn. The upward pressure of the air on the rotary member urges the latter upwardly into contact with the side walls of the housing 1 so as to prevent air losses. Excessive upward pressure on the rotary member may be balanced by admitting pressure to a cylinder 39, Fig. 3, above a piston 40 which is connected 'by a yoke 41, 42 to the shaft of the rotary member. The pressure exerted by the balancing device may be sufficient to draw the rotary member downward into contact with the bottom of the casing and thereby avoid air losses at this point instead of at the intake.

Title: A thermo-responsive electric control device
IPC: H05B1/02
Filed: 1948-01-15
Abstract: 651,731. Control systems for heating resistances. PLESSEY CO., Ltd. Jan. 15, 1948, No. 1290. Convention date, March 14, 1947. [Class 38 (iv)] [Also in Groups XIII and XXXVII] Switching control.-An electrical appliance, such as a range heating element, is periodically energized and de-energized by a thermal switch, the proportion of each cycle during which the appliance is energized being evenly adjustable from 0 to 50 per cent or 100 per cent of the maximum output thereof. In Fig. 2, the thermal switch comprises a sealed chamber 23 having a snap-acting diaphragm 20 and a breather diaphragm 21 respectively controlling snap-action switches 30, 40. Each of these switches, which are similar, comprises a member 32 connected to the diaphragm by a member 34 and to a U-shaped snap-spring 33, which is compressed between the member 32 and a contact-carrying member 31, the spring 33 being movable to and fro over dead-centre by the diaphragm. The chamber 23 contains a fluid which is caused to expand and contract to move the diaphragms by the cyclical energization and de-energization of a heater 25 controlled by switch 30. The appliance 48 is controlled by the switch 40 which is mounted on a spring 49 and is adjustable toward and away from diaphragm 21 by means of a screw 52. In a modification, Fig. 3 (not shown), the diaphragm chamber is replaced by a bellows carrying a contact co-operating with a resiliently mounted adjustable contact, these two contacts re-placing the switch 40. The Specification as open to inspection under Sect. 91 comprises also a further modification, Fig. 4 (Cancelled), wherein a bimetal strip 81 having a heater 80 carries an insulating block 84 attached to the free end of a member 85, which is connected to the contact-carrying member 86 by a U-shaped spring strip 87. The contact 88 alternately co-operates with contacts 89, 90 respectively controlling the heater 80 and connected to the load 96. The strip 81 also controls a switch 98 by means of an adjustable screw 102, the downward movement of contact 97 being limited by a stop 104. Since the switch 98 is in series with contact 90, the maximum energization of load 96 is the portion of the cycle when the heater is de-energized. Specifications 628,304 and 645,154, [both in Group XXXVII], are referred to. This subject-matter does not appear in the Specification as accepted.

Abstract: 1,020,851. Vibration dampers. ROVER CO. Ltd. April 10, 1964 [Jan. 11, 1963], No. 1308/63- Heading F2S. In means for reducing the vibrations transmitted by an I.C. engine or other machine M through its rubber mountings R to a bracket B on a supporting structure S vibrations, detected by an electromagnetic pick-up G, e.g. a strain gauge, mounted on the bracket B, are amplified and fed to the driving coil C of an electromagnetic force-generating unit U and are of such amplitude and phase as to apply, through a rod D, opposing forces to the bracket B which will substantially cancel out forces transmitted to the bracket B through the mounting R. The coil C is received in an annular gap in a magnet which is suspended on low rate springs L, L from the bracket B, the natural frequency of the springs L, L and the magnet being low in comparison with the frequency of vibrations of the machine M. The strain gauge G may be replaced by a transducer T or T<SP>1</SP> disposed directly between the machine M and the bracket B and the circuit may include frequency selective attenuators. The transducer G could respond to velocity instead of displacement and be fed through an integrating circuit and, if desired, an attenuator to produce a voltage proportional to displacement for feeding to an amplifier connected to the coil C. Circuits are also described which include arrangements where forces 180 degrees out of phase with both displacement and velocity are fed to an amplifier leading to the coil C. In all embodiments the phase and amplitude of the output driving coil C may be made adjustable. In Fig. 9, (not shown), a machine M imparts countervibrations to a support bracket B through a lever W and resilient mounting R<SP>1</SP> the free end of the lever W co-operating with a cam Y rotatable by the machine M driven at the appropriate speed. In an alternative arrangement the lever acts upon a resilient mounting R<SP>1</SP> situated on the same side of the bracket as the resilient mounting R.

Title: Improvements in and relating to cam-driven electric switches
IPC: H01H3/42
Filed: 1935-01-15
Abstract: 442,969. Snap-action switches. BRITISH THOMSON - HOUSTON CO., Ltd., Crown House, Aldwych, London. Jan. 15, 1935, No. 1365. Convention date, Jan. 16, 1934. [Class 38 (v)] In a quick-action switch operated by a cam drum 2, the drum acts on the arms 13, 14 of a lever 1 pivoted at 3, the lever 1 having two other arms 15 which embrace a spring 16 arranged between the two arms of a contact lever 4 also pivoted at 3. As shown in Fig. 2, the spring 16 also bears on projections 5 on the arms of the lever 4. When the cam drum is rotated in a counter-clockwise direction, the lever 1 is moved into its dotted position and its upper arm 15 compresses the spring 16 which tends to force the lever 4 into the open position, but this movement is prevented by the engagement of rollers 21, 20 on the arm 4 and a latch 7 until a projection 9 on the lever 1 engages a projection 10 on the latch. In the open position, the roller 21 bears on the opposite side of the roller 20, which prevents movement of the contact arm 4 to close the switch when the cam is rotated in the reverse direction until a projection 11 on the arm 1 engages the end 12 of the pawl. In the event of the contacts sticking, positive actuation is effected by a lug 16 on the lever 1.
