Title: A process for cooling and liquefying gases
IPC: C10G5/06
Filed: 1960-10-21
Abstract: 896,663. Liquefaction of gases. SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ N.V. Oct. 21, 1960 [Oct. 23, 1959], No. 36196/60. Class 8(2). Liquefaction of a gas mixture e.g., natural hydrocarbon gas is effected by heat exchange cooling in at least two stages in series; the coolant in at least the last stage being wholly in the gas phase and that in the immediately preceding stage being an evaporating coolant. In operation the gas mixture is forced by a compressor 1 at 50 atmospheres pressure firstly through a water cooler 2, secondly through exchangers 3-6 traversed by liquid ethane which comprises the evaporating coolant, and finally the so-liquefied mixture is sub-cooled in an exchanger 7 cooled by a closed nitrogen cycle and after expansion to atmospheric pressure at a valve 8 is stored in a vessel 9. Cold vapour from the vessel 9 passes through exchangers 25, 24 and cools nitrogen gas discharged by a compressor 22 prior to its expansion in a turbine 26 the discharge of which traverses the exchanger 7 before being returned to the compressor 22. The evaporating coolant viz., ethane also performs a closed cycle comprising a four stage compressor 13, a condenser 17 cooled by a propane cycle 18, 19, 20 and expansion valves 12, 14, 15, 16 at the inlet of the exchangers 3-6 and serving to cool liquid ethane passing thereto. Ethane vapour from the exchangers 3-6 passes to the inlets of successive stages of the compressor 13. In a modification the gas mixture is liquefied in series arranged exchangers 3, 4, Fig. 2 (not shown), in an evaporating propane cycle and then in exchangers 5, 6 in an evaporating ethane cycle and finally by the old nitrogen gas cycle as described with reference to Fig. 1; the propane and ethane cycles being connected to each other cascade fashion by an exchanger 17.

Abstract: 508,501. Propelling aircraft. BARBAROU, M. J. B. Dec. 31, 1937, No. 36259. Convention date, Jan. 13. [Class 4] Means for propelling aircraft comprise two airscrews mounted on coaxial shafts disposed unilaterally of and geared to one end of a main shaft connected to the aero-engine and supported within a tubular casing secured at its ends to a reduction gear housing containing the coaxial shafts and to the engine casing ; a sleeve surrounds the main shaft and is connected to the shaft by collars and a frictionclutch device. As shown, the airscrews 22, 23 are driven from the aero-engine 1 which is disposed to the rear of the cockpit in order to increase the pilot's field of vision and permit firing a gun through the airscrew shaft. The engine drives a shaft 8 through a pinion 7. The sleeve 10 surrounds and is fixed to the shaft 8. Conical linings 12, 13 are secured respectively to the sleeve and pinion 7 which have differing moments of inertia. A split ring 11 is operated by centrifugal force to co-operate with the linings and damp torsionaloscillations in the shaft 8. The shaft 8 drives, through a pinion 9, a shaft 16 which through pinions 17, 18, 19 and 20, 21 and a further pinion, drives the airscrews in opposite directions through concentric hollow shafts 32, 31. The shaft 32 rotates in a bearing 24 and is centred on rollers 26 and the shaft 31 rotates in a bearing 28a. A gear-wheel pump 34, 35 draws oil through the conduit 36 from the interior of the housing 5 and delivers it through conduits 38, 39 to a radiator 40 whence it passes through a main 41 to a reservoir. A second gear-wheel pump 42, 43 draws oil from the reservoir through a union 44 and delivers it through conduits 45, 46 to the airscrew shafts and also through a tube 47 to the bearings 28, 29 of the shaft 16. Packings 50 and plug 52 prevent leakage. Oil accumulating in the casing 3 can drain through conduit 53 into the interior 37 or pass rearwardly to the engine casing 1. The means for damping torsional oscillations may comprise conical rubber washers compressed between the sleeve and shaft..

Title: Improvements in and relating to machines for feeding rods or tubes of fragile material
IPC: B65G47/14
Filed: 1934-12-19
Abstract: 449,166. Feeding hoppers ; making electric lamps. BRITISH THOMSONHOUSTON CO., Ltd., Crown House, Aldwych, London. Dec. 19, 1934, No. 36433. Convention date, Dec. 20, 1933. [Class 78 (i)] [See also Group XI] Devices for feeding lengths of rod or tubing of glass &c. as in the lamp-sealing machine described in Specification 252,395, [Class 39 (ii)], consists of a hopper having oppositely disposed apertures in the walls through which the rods are delivered by a reciprocating ram. The rods are transferred to the sealing machine by a carriage which has a linear reciprocating movement and a rocking movement about a pivot. The mass of rods in the hopper is, agitated by giving the ram a lateral movement by a reciprocating bar pushing up through the bottom of the hopper and by a vibrating device acting on the bottom of the hopper. The hopper 11, Fig. 2, has an inclined bottom 17 and oppositely inclined false bottom 16 and a partition 18 which forms a passage through which a small number of rods gravitate to the feeding position at the lower left-hand corner. At this point aligned openings are formed through which a reciprocating ram operates to push out the rods in succession. The ram is also given a lateral movement to agitate the mass of rods, and a knocking device 52 acts on the bottom of the hopper for the same purpose. A separator 51 is attached to the knocker 52 and works through the bottom of the hopper to isolate the rod which is in feeding position from the others. The operative movement of the ram is obtained from a spring and its return movement by a cam. The lateral movement is obtained by mounting it in a guide which performs a vertical reciprocatory movement under the action of a cam and spring mechanism. The rods are delivered to a transfer mechanism shown in Fig. 4, comprising a carrier with grooved blocks 66 and spring-actuated clamping fingers 71. The carrier is hinged to a slide and co-operates with a cam-groove in the fixed part of the machine so that when the slide is moved from its receiving position the carrier is turned through 90‹ about its pivot. The jaws of the sealing - machine then grip the rod between the fingers 71 and pull it out. In the receiving position, the fingers 71 are held up by a rod 78 engaging a fixed part of the frame. A feeler device is provided acting in conjunction with the sealing-machine to stop the feed of rods when a lamp is missing from the sealing head. This is done by a stop member interposed in the path of the ram.

A control assembly for a fluid pressure operated apparatus comprises at least one fluid pressure valve 15, 31 connected to an operating member, e.g. a pedal 34, through an intermediate link which is formed in two parts having a lost-motion connection therebetween. The two parts are adapted to generate fluid pressure upon relative displacement on failure of the fluid pressure valve 15, 31. The two parts may comprise a cylinder 35, and a spring-loaded piston 36, a pallet 33 being pivoted about an end of cylinder 35 and abutting two valve members 16, 32. The fluid pressure system associated with front wheel brakes 1b 2b and valve 15 comprises a reservoir 5, pump 6, relief valve 9, accumulator 10 and a one-way valve 13. A similar system is associated with the rear wheel brakes 3a, 4a and a second set of front wheel brakes 1a, 2a. Piston 36 moves within cylinder 35, closing line 40, the cylinder 35 then moving to actuate valve members 16, 32. Member 16 moves against spring 22 to open line 14 to line 17, thus allowing pressurized fluid to actuate brakes 1b 2b. Pressurized fluid also acts through a line 19 against member 16 to maintain a back pressure on pedal 34. If pump 7 fails, piston 36 forces fluid through a non-return valve 42 to operate brakes 1b 2b. If the supply of fluid to cylinder 35 fails, piston 36 engages abutment 44 to operate valve members 16, 32. A second embodiment comprises two closed circuit fluid brake systems in which the control valves variably throttle the flow in response to the pressure generated in the cylinder by the pedal and piston.

[Class 46.] In filters in which the charge material is disposed above a retaining member, especially in such filters for purifying water, the direction and rate of flow of the liquid are controlled by one or more baffleplates under the member so that accumulating gas bubbles are transported to an outlet. A charge 6, such as active carbon, is supported by a perforated plate 3. Liquid entering the filter is deflected by a baffle plate 2 so that liberated gas bubbles are guided to an outlet 4. To facilitate the action the perforated plate may slope up from the sides to the outlet at the centre. In another embodiment to facilitate removal of bubbles, a circulation of the liquid is set up in the lower part of the filter by a special form of baffle-plate. The baffle-plate and retaining member may also be obliquely disposed and the gases removed at the side. Another form (Fig. 5) comprises also a combination of sieves and perforated plates 32 offering a sudden resistance to the flow thereby liberating occluded gas bubbles 33 which ascend into an upper space 34 and are led away by openings 36 to an outlet 37. A circulating flow may be induced by vanes in order to sweep the bubbles up to the space 34.
