IPC: F01L1/12
Filed: 1921-03-02
Abstract: 171,400. Neyret, J. March 3, 1920, [Convention date]. Valve-gear.-The inlet and exhaust valves 25 of the engine described in Specification 159,830 are actuated by a double-armed lever 26 rocked about a fulcrum 28 by a tappet rod 27, which is pushed upwards by a cam 32 and lever 29, 29<1> to open the inlet valves, and is pulled downwards by a cam 33 and lever 30 to open the exhaust valve, the lever 30 engaging a slot in the bottom of the tappet rod 27. The cams are integral and mounted on a spindle 24 driven by a crank arm 22 formed with a slot 22<1> engaging in an annular groove in the crank pin 21. The tappet rod 27 is moved laterally so as to engage the lever 29<1> during one revolution and the lever 30 on the next revolution, by means of a star wheel 43 which is rotated one-sixth of a revolution during one revolution of the crank shaft by a pin 42 formed in one with the crank arm 22. A three-lift cam 44 secured to the star wheel moves a stirrup 45 about its pivot 45', and thereby the tappet rod 27, from one side to the other during each revolution. Valves.-The tappet rod 27 carries a collar 48 which is pressed on opposite sides by springs 46 fixed to a support 47.

Abstract: 1487466 Liquefying natural gas LINDE AG 21 July 1975 [9 Aug 1974] 30406/75 Heading F4P Natural gas 1 is liquefied by a first multicomponent refrigerant and then a second multi-component refrigerant, each refrigerant being in a respective closed circuit, the first circuit being such that the refrigerant is compressed at 27, 28, 29, partially liquefied by cooler 30 and then separated at 31, the liquid fraction being sub-cooled at 60 and then undergoing successive stages of expansion and separation at 32, 33, 36, 37, 40, 41, a part of each liquid fraction being passed to lines 34, 38, 42 of respective exchangers 2, 6, 7 to cool the natural gas before being returned to the separator from whence they came, whilst the gaseous fraction from separator 31 is cooled in exchangers 2, 6, 7 and 11 before expansion at 44 and passage to separator 41 via exchanger 11, and the second refrigerant circuit being such that the refrigerant is compressed at 45, cooled at 46, partially liquefied in exchangers 2, 6, 7, 11 and then completely liquefied in exchanger 13 in heat exchange with lowerboiling component of the natural gas and itself, it then being returned to compressor 45 via expansion valve 59 and exchanger 13. The feed gas 1 is cooled at 2 to condense out C 5  and higher hydrocarbons and water which are separated at 3. The remaining gas is dried and passed to exchangers 6, 7 where it is partially condensed before moving to a rectification column 8. The sump product of ethane, propane and higher-boiling hydrocarbons is withdrawn at 10 and the gaseous head product of N 2 , methane and ethane, and small quantities of propane and butane, is passed through exchanger 11 for partial condensation before reaching separator 12. The gaseous fraction is liquefied and subcooled in exchanger 13 before passing via exchanger 25 and ejector 14 to column 15. The overhead N 2 -rich product is passed back through exchangers 11, 7, 6, 2. The second circuit may have a two stage compressor with an extra exchanger from which is fed an intermediate refrigerant portion to the second compressor stage (Fig. 2, not shown). Alternatively, the second refrigerant can be separated before being used in a pair of exchangers replacing 13 (Fig. 3, not shown). The successive liquid fractions in the first circuit may be increased in pressure before performing their cooling function, and they are then returned to the preceding separator (Fig. 4, not shown). Finally, an extra separator may be located between 31 and 33, the gaseous fraction being combined with that from 31 after cooling at 2, 6, 7, 11 and expansion (Fig. 5, not shown).

Abstract: 422,299. Loud-speakers. GENERAL ELECTRIC CO., Ltd., Magnet House, Kingsway, London, and OLIVER, D. A., c /o General Electric Co., Wembley, Middlesex. Nov. 3, 1933, No. 30608. [Class 40 (iv)] Relates to an electrostatic loud-speaker of the type in which a constant polarizing voltage is maintained between the two electrodes during operation and in which the moving electrode is so flexible that it would be greatly deformed by the force of mutual attraction arising from the polarizing voltage unless that force were opposed by another force. According to the invention, all that part of the space between the two electrodes which is not occupied by solid dielectric is occupied by fluid whose pressure and whose dielectric strength are both greater than that of air at atmospheric pressure. The fluid is preferably air at a pressure substantially exceeding atmospheric. If desired, a stop may be provided outside the moving electrode against which the latter can rest when the polarizing field is not applied and the pressure of the medium is uncompensated. Specification 139,497, [Class 40 (iv)], is referred to.

Abstract: 1,123,918. Stacking record cards. UPTIME CORP. 8 July, 1966 [20 Oct., 1965], No. 30694/66 Heading B6H. [Also in Division G4] As cards are fed in succession to an output hopper, predetermined cards 110 are deflected so that they are offset in relation to the remainder in the stack 20. One device for offsetting cards 110 is a roller 62 which, in its neutral position, has its axis parallel to that of a cooperating roller 60. Energization of solenoid 96 rotates bracket 64 about shaft 80 so that roller 62 becomes inclined to the direction of travel of cards entering the hopper and imparts transverse motion thereto. Alternatively, the axis of roller 62 may be fixed and a braking force applied to the top edge of the selected cards entering the hopper. Another device comprises a ramp which is movable into a card engaging position to force selected cards entering the hopper into an offset position. Selected cards may be offset longitudinally of the stack by means of a stop which is movable to intercept the leading edge of a card entering the hopper. The devices may be controlled by a data processor coupled to a card reader to effect card selection or sorting by offsetting selected cards.

Title: Improvements relating to loom stop motions
IPC: D03D51/00
Filed: 1932-11-01
Abstract: 409,666. Measuring stop-motions for looms. FROST, W. H., 307, Colne Road, Burnley. Nov. 1, 1932, No. 30701. [Class 142 (i).] In a device for measuring the length of cloth or counting the number of weft picks that can be woven with one cop &c. and for causing a stop motion to come into action by a lever h, h<2> falling into a gap in a member, as described in Specification 307,953, [Class 142 (i)], an endwise movable stepped shaft b, b<1>, b<2> formed of three diameters and mounted in a casing A, carries clutch members C, E and a collar F. The member C is driven by worm gearing from a shaft d<1>, which is driven by ratchet gearing and adjustable lever mechanism from a crank or eccentric adjustably mounted on the loom bottom shaft. A spring f acting on the collar F causes a ball thrust bearing thereon to move the member E, which operates the stop motion, into frictional driving engagement with the member C. This is engaged by corks e, a tension spring e<4> tending to resist the rotation of the member E. The collar F is first turned by worm gearing from a hand operated setting wheel g2, Fig. 2, until a stop f on the collar is in the desired starting position relatively to a stop e<2> on the clutch member E, which at this time is held by the engagement with a gap e<1> therein of a finger h<3> on the lever h, h2. The lever h, h<2> is now raised out of the gap in the member E, which is then rotated by the spring e<4> until its stop contacts with the stop on the collar, the arm h of the lever h, h<2> having moved the stepped shaft endwise so that a shoulder on the part b has disengaged the member E from the worm driven clutch member C. The lever h, h<2> is now lowered on to the periphery of the member E, so that the arm h allows the stepped shaft to be moved endwise to the left by the spring f and the member E to be driven by the clutch member C, whereby it is slowly rotated until its gap allows the lever h, h<2> to fall. When this occurs, by means of devices described, a lever pivoted on a bracket on the starting handle is rocked into the path of a collar on a rod operated by a crank pin &c. on the bottom shaft. The starting handle is thus operated to stop the loom. The collar F is prevented from making more than one revolution by means of a screw e<5>, which can engage the stop on the collar.
