Abstract: 303,159. Dunham Co., Ltd., C. A., (Assignees of Crosthwait, D. N., and Dunham, C. A.). Dec. 30, 1927, fConvention date]. Steam traps.-In a steam trap employing an outlet valve operated by a thermostatic capsule containing a volatile liquid, a liquid mixture is employed having a vapour pressure in excess of that of saturated steam by an approximately constant amount. The liquid may consist of benzene 99.5 per cent by volume, and denatured alcohol 0.5 per cent. The alcohol contains 5 per cent water, the remainder being ethyl alcohol 10 parts, and methyl alcohol 1 part. Specification 241,511 is referred to. The Specification as open to inspection under Sect. 91 (3) (a) describes also a steam trap suitable for the outlet of a steam-heated radiator comprising a flexible metal capsule 13 containing a volatile liquid and carrying a valve 16 controlling the outlet 18. The capsule is adjustably mounted in the cover 15 of the casing. Another suitable mixture comprises distilled water 71.5 per cent by volume, denatured alcohol 28 per cent. and benzene 0.5 per cent. The proportions may alternatively be chosen so that there is a gradual increase in the vapour pressure relatively to that of steam, with rise of temperature. The excess of vapour pressure may be about 111b. per sq. in. This subject-matter does not appear in the Specification as accepted.

Title: Spindle driving and clutching means for spinning and twisting spindles
IPC: D01H1/24
Filed: 1959-11-20
Abstract: 881,669. Driving and braking spindles. BURKHARDT, O. W. Nov. 20, 1959 [Nov. 29, 1958], No. 39395/59. Class 120(2) [Also in Group XXIV] In a spinning or twisting spindle 1 driven, via a clutch incorporating a slidable sleeve 13, 14, by a spindle sleeve 7 which surrounds the spindle, the clutch sleeve, which is operated by one or more electromagnets 20 in the spindle housing, is slidable on the spindle and couples the driving sleeve to the spindle in its one end position and effects braking of the spindle in its other end position. In Figs. 1 and 2 the clutch comprises a ring 11 in the sleeve 7 which is driven by a worm-wheel 10 and the clutch sleeve 13, 14 sliding on an octagonal section 12 of the spindle. The clutch sleeve consists of an inner brass member 13 and a steel sleeve 14 having teeth 18, 19 engaging clutch shoes 16 and 17 which are outwardly urged by springs (not shown). Braking of the spindle is effected by energizing the electromagnet 20 which causes the sleeve 13, 14 to slide upwards into frictional contact with a steel ring 15 fixed in a spindle housing 2. At the same time the teeth 18, 19 arrest the shoes 16 and 17 which then slide over a wear-resisting lining of the ring 11, so decoupling the spindle drive. When the magnet is again de-energized, the shoes 16, 17 are no longer arrested and again, under the influence of the spring force and centrifugal force form a driving connection between the spindle and its driving sleeve 7. In a further form (Fig. 4, not shown) another electromagnet is provided in the spindle housing which, when energized, brings the sleeve 13, 14 downwards into contact with a ring fixed to the sleeve 7 so providing frictional coupling between the driving sleeve 7 and the spindle 1; use of a changeover switch in the electromagnet circuit ensures that both electromagnets cannot be simultaneously switched on.

Abstract: 1,195,981. Friction clutches; reverse gear. SPERRY RAND Ltd. 16 Aug., 1968 [1 Sept., 1967], No. 39998/67. Headings F2C and F2D. Each clutch, e.g. 14, of a pair of main clutches 14, 14<SP>1</SP> comprises a nylon coil spring 24 which normally freely surrounds a drum 23 secured to or formed integrally with a shaft 16. The ends of the spring are secured to adjacent gears 21, 26 which mesh with corresponding gears 21<SP>1</SP>, 26<SP>1</SP> of the other clutch. The gears are rotatable on the shafts 16 and 161 and a common output shaft 11 carries a gear 27 which meshes with the gear 26. Nylon gears 13, 13<SP>1</SP> fast with the shafts 16, 16<SP>1</SP> are driven by a common input shaft 12. Each main clutch is controlled by an auxiliary clutch comprising a stationary solenoid 15 which, on energization, causes a clutch plate 19, secured to the shaft 16, to engage a clutch plate 20 secured to the gear 21. When clutch 14 is to be engaged, its auxiliary clutch is operated and drive imparted to the gear 21 which causes the spring 24 to wind up and grip the drum 23. High torque drive is thus transmitted, via gears 26, 27 to the output shaft 11 in the same rotational sense as the input shaft 12. For a reverse drive, solenoid 15 is de-energized and clutch 14<SP>1</SP> is engaged, rotation of the shaft 11 in the opposite sense resulting from drive from the gear 26<SP>1</SP>, via gear 26 to gear 27. When clutch 14 (or 14<SP>1</SP>) is engaged the gearing ensures that the spring 24 (or 24<SP>1</SP>) of the non-operated clutch is given a short unwinding motion. The arrangement is applicable to automatic steering, e.g. of a rudder or fin. Aluminium gears and steel springs may be used.
