Class 80 (2) [Also in Group XXXI] In a differential gear, comprising an over- 'running clutch having toothed members disengaged by cam means, hold-out means are provided to maintain the cam means disengaged so long as overrunning continues. As shown for application to the transfer box of a fourwheel-drive vehicle (see Group XXXI) a gear wheel 30, Fig. 3, bolted to the differential casing 28 is driven from the vehicle engine. A member 35 also secured to the casing 28 has radial teeth 47 on each face engageable with teeth 48 on members 36, 37 splined at 52, 53 to shafts 33, 34 respectively connected to the front and rear axles of the vehicle. The member 37 is held permanently in engagement with the member 35 by a ring 55. A spring 40 bears against a ring 42 splined to the shaft 33 and against the member 36 which it urges toward engagement with the member 35. Cam teeth 50 on the members 36, 37 urge the member 36 out of engagement with the member 35 when the shaft 33 rotates faster than the shaft 34. Hold-out rings 38, 39 are axially fixed - relatively to, and frictionally rotatably connected to, members 36, 37 by polygonal spring rings 59 disposed in. circumferential grooves 60 in those members. Each ring 38, 39 has axially directed projections 58 provided with shoulders 63 which, when the member 36 is cammed from the engaged position shown in Fig. 7, to the disengaged position shown in Figs. 8 and 3, co-operate to move and maintain the camming teeth 50 out of engagement. Thrust washers 61 are provided between the rings 38, 39 and the members 36, 37. The projections 58 are so proportioned that in the engaged position of the member 36. (Fig. 7) they overlap by an amount x which is at least equal to, and preferably slightly greater than, the axial length of the cam teeth 50. In a modification, Figs. 9-11 (not shown), the gear is not symmetrical and only one hold-out ring is provided which co-operates directly with a member on the shaft 34. Specifications 560,648 and 561,350 are referred to.

Title: Improvements in or relating to method and apparatus for producing purified water from aqueous saline solutions
Inventor: DONATH WILM ERNST
IPC: C02F1/26
Filed: 1959-09-01
Abstract: 867,469. Purifying sea water. KOPPERS CO. Inc. Sept. 1, 1959, No. 29792/59. Class 46. Ocean water enters hydrateforming vessel 1 by means of line 2 and is maintained in vessel 1 under pressure sufficient for hydrate-formation at the temperature provided by cooling jacket 3, hydrateforming gas, for example, chlorine, argon, ethylene, acetylene, methyl chloride, ethyl fluoride, methane, ethane, propane, nbutane, isobutine, or carbon dioxide, or mixtures of the same, is added under the pressure maintained in vessel 1 through line 6 by means of a distributer or sparger (not shown), and the solid hydrate formed in vessel 1 and floating in the salt solution is removed from it by means of feeder or conveyer 7 and carried into hydrate-decomposition vessel 8. On the inclined part of the feeder 7 connecting vessels 1 and 8, excess water drains to vessel 1. A liquid level in vessel 1 is maintained to permit hydrate removal by feeder 7 by means of valve 9 that controls discharge of water enriched in salts into receiver 10 maintained at atmospheric pressure. Dissolved hydrateforming gas that is released from the enriched salt solution upon depressuring in receiver 10 leaves through line 11 into compressor 12 and is recycled into vessel 1. Make-up hydrateforming gas can be added, if necessary through line 13 or 14. Solid hydrate preferably washed is discharged into the hydrate-decomposing vessel 8 and is decomposed by heat supplied from heating jacket 15. Gas liberated from the hydrate leaves vessel 8 through conduit 18 and is recycled by means of pump 19 and line 6 into vessel 1. The hydrate-forming gas can return from vessel 8 to the vapour space of vessel 1 without use of recycle pump through the housing of the conveyer connecting these two vessels. In this case, the hydrate-forming gas is absorbed at the surface of the solution contained in vessel 1 or by water sprayed into vessel 1. Purified water in vessel 8 is depressured by means of valve 20 into receiver 21. Dissolved hydrate-forming gas which is liberated by the pressure decrease leaves through line 11. Purified water is discharged through line 22 and may be freed of dissolved hydrate-forming gas in an aerating tower (not shown), or by vacuum treatment. Enriched salt water leaves receiver 10 by means of conduit 23 and can be freed of residual dissolved gas similarly. The hydrate may be decomposed by pressure decrease alone as described in the embodiment of Fig. 2 (not shown).

X is cut out in the " distant position of switch 2..A third switch 11 controlling the high-frequency selectivity of the receiver may be jointly controlled with the other two. Alternatively, the audio-frequency control may comprise a condenser switched across the primary winding of the output transformer, Fig. 1 (not shown). The object is to remove excessive interference on long distance reception.

Abstract: 480,198. Thrashing-machines. MARTINEZ, A. B. Nov. 4, 1936, No. 29955. Convention date, Nov. 8, 1935. [Class 58] Grain passes from a feeding table 1 to a preliminary beater 2 and concave 3 through which it passes to one end of the main thrashing chamber 4 containing a beater 5. The perforated lower part of the chamber 4 is semicircular in cross-section but the upper part of the chamber is bulged out so as to provide a space above the range of the bars of the beater 5 and this part is provided with helical guides 6 by which the material being thrashed is directed along the chamber. The inclination of the guides may be adjusted to vary the speed of the material through the chamber. The beater bars may be provided with teeth or may have walls extending longitudinally ; successive bars may be connected by walls to exert radial pressure during thrashing. The material after passing along the chamber is thrown upwards by the beaters through an opening 15 against a plate 17, a blast of air from the fan 8 then carrying it through an adjustable discharge opening. The grain, short straw, &c. that fall through the perforations in the lower half of the casing are carried by a conveyer 9 to an elevator 10 which discharges them on to a pan 11 feeding an oscillating sieve 12 ; clean grain passing through the sieve falls on a lower oscillating plate 13 and small pieces of straw are blown away by the fan 8. Any grain carried with the straw is trapped by a plate 14 and falls into the thrashing chamber again. A fine sieve 24 at the lower end of the plate 13 removes the smaller impurities from the grain which falls into one or other of two independent channels 19, 20 leading to outlets at the sides of the machine. A gate 18 controls the blast from the fan. The cylinder 2 may be detached, the material then being fed directly to the chamber 4.

Title: Improvements in centrifugal pumps

Filed: 1964-07-28
Abstract: 1,110,107. Centrifugal pumps. HAYWARD TYLER & CO. Ltd. (A. Ivanoff). July 28, 1965 [July 28, 1964], No.29985/64. Heading F1C. In a centrifugal pump and motor combination, the pump has one or more impellers 9 mounted on a pump shaft 3 coupled to the motor shaft 4 by a flexible coupling 6, the stiffness of the coupling (which, as shown, may be of spherical bonded rubber type) being such that the primary critical speed of the system including the pump shaft the impeller or impellers and the coupling is substantially below the running speed of the motor 1 and the stiffness of the pump shaft being such that any secondary critical speeds are substantially above the running speed. Despite unbalance caused by uneven wear due to the abrasive material contained in the sandy water being pumped, the axis of rotation coincides (or very nearly coincides) with the centre of gravity of the shaft 3 and its impeller or impellers. Lateral deflection of the shaft 3 occurring during acceleration through the primary critical speed is limited by a steady bush 7 having a large radial clearance about the shaft. A porous bush 8 allows the escape of air as the bush fills with water but prevents the entry of downwardly dropping sand when the pump is stopped. To allow the lateral deflection, a gap is left between the lower face of the impeller (preferably faced with hard metal) and the co-operating surface of the pump casing (preferably faced with a rubberlike plastics material 11 to allow passage of sand through the gap without serious impeller wear).
