IPC: C01B17/50
Filed: 1930-06-06
Abstract: 353,618. Separating gases by liquefaction. IMPERIAL CHEMICAL INDUSTRIES, Ltd., Millbank, London, and HARROLD, A. W., Charnwood, Hillside Drive, Woolton, Liverpool. June 6, 1930, No. 17499. [Class 8 (ii).] Sulphur dioxide, chlorine, and other easily liquefiable gases diluted with air &c. are compressed and liquefied in stages, in the first stage by evaporation of a low boiling liquid and in the second stage by expansion of the residual permanent gas. Gas mixture from a pyrites burner is compressed by a compresser 2, cooled in an exchanger 3, and partially liquefied in a vessel 4 containing a coil 5 cooled with liquid carbon dioxide in evaporation ; the liquefaction of the sulphur dioxide is completed in a vessel 6 the residual gas from which is expanded in a motor 8 and conveyed through a coil 7 in the vessel 6 to effect the liquefaction, and through a coil 9 to cool the exchanger 3. In a modification a part of the compressed gas is byepassed to heat the permanent gas before entering the motor 8. In a further modification the compression and expansion are effected in stages.

Title: Improved escapement mechanism
IPC: G04C13/12
Filed: 1946-06-12
Abstract: 613,236. Escapement mechanism. LANDIS & GYR SOC. ANON. June 12, 1946, No. 17569. Convention date, June 21, 1945. [Class 80 (iv)] [Also in Groups XIX and XXXVIII] An escapement mechanism for use in counting, calculating, signalling or switching apparatus, comprises a shaft 1 which is adapted to be released to describe a single complete revolution on successive actuating impulses. As shown, the shaft operates a printing device 3 and is driven by clockwork 5 which is wound up by an electric motor 6. At one end, the shaft carries an arm 7 on which is mounted a pivoted rocker 10 having a projection 11 engaging with lost-motion in a slot 12 of the arm 7. A fork member 13 integral with a pivoted armature 14 of an electric relay 15 carries two abutments 16, 17 for engagement with the ends of the rocker 10. In the position shown, the rocker 10 is engaged by the abutment 16 and the lost-motion between the projection 11 and slot 12 brings the free end of the rocker in front of the abutment 17. On an impulse being supplied to the relay 15, the armature 14 is rocked to release the rocker 10 to allow the arm 7 and shaft 1 to rotate for one complete revolution when it will then be stopped by the other end of the rocker 10 engaging the abutment 17. On a further impulse, the abutment 17 disengages to allow another revolution and so on. In a modified arrangement, the arm 7 is carried on a planetary pinion rotatably supported on a second arm on the shaft 1 and geared to a fixed re-action gear. The planetary pinion is adapted to make a definite number of revolutions for one of the shaft 1, when the arm 7 will return to the same position relative to the abutments 16, 17, so that the retaining force on the abutments and rocker 10 is reduced in proportion. In a further modification, the rocker 10 is carried on the pivoted armature 14 and the abutments 16, 17 formed on the arm 7.

Title: Improvements in speed-regulators for water and other power machinery
IPC: G05D13/00
Filed: 1919-07-17
Abstract: 144,903. Jensen, R. L. July 17, 1919. Transmitting mechanism.-In a governor for water and windmills, turbines &c., in which a centrifugal governor is caused to actuate a clutch whereby a regulating-shaft is set in motion, and provided with means for restricting the governing effect within limits, the governor 10 is driven by gearing 5, 7, and pulley 6 from the machine the speed of which is to be regulated. Two clutch members 18, 19, adapted to engage a clutch member 17 feathered on the shaft 4, are driven in opposite directions from the wheel 5, by gearing 21, 20 and 26, 24, 23 respectively. Any variation in the speed causes the governor 10 to move the member 17 into engagement with one or other of the members 18, 19, and the shafts 4, 35, to operate a lever 46, or alternatively a worm-wheel 52, to control the water supply to or effective sail area of the rotor. In order to restrict the regulating effect within limits, the shaft 35 is driven from the shaft 4 by means of a clutch A, comprising ratchet-wheels 27, behind each of which is a disk 29 carrying a stud 28, which is forced into engagement with the opposite ratchet-wheel by springs 30. A slide 51 operated by the lever 46 or worm-wheel 52, on the predetermined regulation having been effected, actuates one or other of the levers 31, 40 and withdraws one or other of the studs 28 from the co-operating ratchetwheel and arrests the movement of the shaft 35. Several studs 28 or power adapted to be put into or out of action by movements of the disks 29 may be employed. In a modification in which the shafts 4, 35 are made in one piece, the regulation may be limited by means of a rod 54 connected to the lever 46, adapted to return the clutch member 17 to its neutral position. To facilitate starting or stopping, the nut 45 is preferably in the form of a half-nut, moved into or out of engagement with the screw by means of a rack and pinion actuated by an endless chain.

Abstract: 1,016,638. Clockwork winding mechanism. JECO CO. Ltd. April 30, 1964, No. 17980/64. Heading G3T. An automatically wound clock comprises an electric motor 1, Fig. 1 not shown, a gear 13 to which rotation of the motor 1 is transmitted through a pinion 2 and gears 4 and 10, a main spring 17 one end of which is connected to the gear 13, a gear 15 connected to the other end of the spring 17, a clock train 21 driven by the gear 15, an arm 14 carried by the gear 13 and able to move angularly with respect thereto, an arm 16 similarly carried by the gear 15, a cam having surfaces 24 and 25, Fig. 7A not shown, to be engaged by the arms 14 and 16 respectively, and a set of contacts 29 and 30 carried by springs 26 and 27 which engage the surfaces 24 and 25 respectively, so that when the cam is rotated by the spring 17 through the arm 16 the contacts 29 and 30 are closed to actuate the motor 1 and wind the spring 17, and when the cam is further rotated by the motor 1 through the pin 14 the contacts 29 and 30 open to stop the motor. Arm 16 makes one revolution every 10 minutes, and when the motor 1 is winding the spring 17, arm 14 rotates at a faster rate of one revolution every two seconds, this ensures that the cam closes the contacts 29 and 30 to cause the motor to wind the spring 17 every time the spring has unwound by one revolution. Gear 13 is prevented from rotating in a reverse direction by a mechanism 31, Fig. 2 not shown, which includes a plate 7 held in frictional engagement with the gear 10 by a spring 6. Plate 7 has two arms 8 and 9, the arm 8 being movable in a slot 12 in the base plate 11. During forward rotation of the gear 10, plate 7 is moved so that the arm 9 is clear of gear wheel 13, but reverse rotation of the gear 13, by the spring 17, is prevented by rotation of the plate 7 to bring the arm 9 into locking engagement with the gear 13. The gears 10 and 13 may be friction rollers.
