Title: Uncoupling valve for hydrostatic transmission
IPC: F16K17/04
Filed: 1970-01-30
Abstract: 1,222,200. Hydrostatic transmission. CESSNA AIRCRAFT CO. 30 Jan., 1970 [7 Feb., 1969], No. 4574/70. Headings F2C and F2D. In an hydrostatic transmission comprising a pump 12 and a motor 14, valves 52, 54 in a ported plate 15 are acted on by opposing pump delivery pressure 38 or 40 and make-up fluid pressure 47 from an input-driven pump 50, to connect the pump delivery to exhaust when a predetermined pressure differential exists across the valve, to move the transmission to neutral. The opposing pressures act on different area sizes (53), (59), Fig. 3 (not shown), at opposite ends of a valve member (62) axially slidable in a valve body (56) to connect the high pressure line 38 or 40 to lubrication exhausts (61), the make-up fluid being delivered to the valves 52, 54 from the pump 50 via lines 51, 46, and to the low pressure line 40 or 38 for make-up via one-way check valves (44), (48), Fig. 2 (not shown), in radial parts 45 in line 46. The valve member (62) may additionally be biased by a spring (75), Fig. 4 (not shown), against the make-up fluid pressure. A manual override control for the valves 52, 54 may be used to move the transmission to neutral at will. It may comprise a valve between the pump 50 and valves 52, 54 manually controlled to connect the pump 50 to exhaust, or a mechanical clutch may be included between the driving engine and the drive shaft 13 driving the pump 50. Either control drains make-up fluid from valves 52, 54 to open the valves. As shown, the pump and motor are of the axial-piston type with the pump barrel 16 fast with the drive shaft 13, the motor barrel 21 fast with a fixed shaft 31, and the output taken from a rotatable casing 29 carrying the swashplates 20, 30 and the ported plate 15. Again the motor barrel may rotate, and the ported plate be stationary.

Abstract: <PICT:0460478/III/1> Oil used to absorb benzene from coal-distillation gases is reconditioned by washing the hot benzene-saturated oil with hot water, and separating by gravity while substantially at rest. Suitably, the oil at 70 DEG  C. is fed through a pipe 5 and hot water under pressure through a pipe 9, the mixture passing down a pipe 4 and rising in a pipe 7 to a gravity separator 3; water rises in a bell 2 and overflows to an outlet 51; oil and heavier impurities overflow from the separator and sink in the bell 2, the impurities collecting at the bottom of a casing 1 and being withdrawn through a tube 16 and adjustable overflow 17, while the clean oil rises between the casing 1 and the bell 2 to an outlet 14. The hot water may be condensate from the oil heater; it may be introduced by a steam injector connected to an inlet 9; and it may raise the temperature of the oil to above 90 DEG  C.

Title: Improvements relating to the fixation of nitrogen
IPC: C01C3/00
Filed: 1922-02-23
Abstract: The extraction of titanium from the titaniferous iron ores, rutile, anatase, &c. together with the fixation of nitrogen is effected by heating in nitrogen a mixture of the ore, charcoal, and enough alkali salt such as sodium carbonate to convert all the titanium into alkali titanate.  The heating is effected at not more than 1850 DEG  C. Ammonia is obtained by treating the product with steam at a temperature not above 1800 DEG  C.  The residue is washed to obtain a titanate from which titanium oxide is obtained by hydrolysis or by treatment with acids.  The Specification as open to inspection under Sect. 91 (3) (a) includes the use of a salt of an alkaline earth or of a metal instead of an alkali salt, and states that if it is not required to extract titanium from its ores, the ore is heated in nitrogen with carbon only, the product being steamed to obtain ammonia, and the residue being used again.  This subject-matter does not appear in the Specification as accepted.ALSO:The extraction of titanium from titaniferous iron ores, rutile, anatase &c., together with the fixation of nitrogen is effected by heating in nitrogen a mixture of the ore, charcoal, and enough alkali salt such as sodium carbonate to convert all the titanium into alkali titanate.

Title: Improvements relating to railway vehicle brake rigging
IPC: B61H13/24
Filed: 1958-02-19
Abstract: 820,778. Railway brake rigging. WESTING- HOUSE AIR BRAKE CO. Feb. 19,1958 [Feb. 25, 1957; Sept. 5, 1957], No. 5365/58. Class 103 (1). In railway brake rigging, the brake cylinder 10 is secured to the brake beam 3, as by means of bolts 14 and straps 24, as shown in Fig. 1, and the piston 13 has a hollow piston-rod 12 that extends through the cylinder base-plate and the beam and has its end secured to a footplate 16 secured on the bolster by a pin 19. Application of fluid pressure to the spaces between the end of the piston 13 and the cylinder causes the latter to move away from the bolster carrying with it the brake beam 3 and the brake heads 7 at each end, the ends of the beam 3 being guided in guide feet 4 of channel section. In such construction since, even if the shoes 8, which are of composition friction material, instead of the cast iron generally used, wear completely away, the piston 13 will not have been moved through its full travel to compress the spring 21. It is, therefore, not necessary, with such construction, to provide any form of automatic wear adjustment mechanism. The clearance of the foot-plate 16 in the bracket 20 secured to the bolster 15 allows for some freedom of motion for the brake beam to allow for uneven wear of the plates 5. The construction shown in Fig. 5, includes two brake cylinders 31 and 32 spaced apart on the brake beam 3, a strut 33 being interposed between the beam 3, and the strap 24, the strut having a slot 34 therein, in which is pivoted a lever 35 whereby the brakes may be applied by hand mechanism. In Fig. 7, there is shown a brake mechanism, wherein the braking cylinder 112 is secured to one brake beam 103, and the piston has a thrust-rod 121 extending therefrom and secured to the other brake beam 104, handoperated mechanism 136, 138, 139 and 141 being pivoted to the rod 121 by pin 140.

Abstract: 656,613. Knot-tying devices. BARBERCOLMAN CO. Feb. 24, 1948, No. 5448. Convention date, Dec. 17, 1938. [Class 112] In a knotter for tying figure-eight knots and comprising a tying bill 15 having clamping and shearing blades 16, 19, 22, and guides 29, 30 having upstanding hooks 29a, 30a, the bill makes two revolutions per knot and is upstanding when the threads a to be tied are laid in the hooks and across the shank of the bill. The guide 30 is longitudinally movable to cause the threads to be across the path of the open blades during the first revolution of the bill and to be seized between the blades during the second revolution. The guide 29 co-operates with clamps 34, the arrangement being that during the second revolution of the bill the guide swings away from the bill to strip the finished knot therefrom. The knotter is actuated by downward movement of a lever 23 from the position shown in Fig. 1. The lever carries a quadrant engaging a gear on the bill shaft the arrangement being that the bill commencing its rotation by turning towards the guide 30 which is initially in a projected position. The movable shearing blade 18 has a cam so shaped that during each rotation of the bill, the blades, initially partly open, are open during substantially the first 180 degrees of revolution and are closed during the substantial part of the remainder of the revolution. A cam carried by the quadrant actuates a bell crank 42 and a link 43 so that the guide 30 is retracted after the first half revolution of the bill, and is again projected towards the end of the bill's second revolution. The clamps 34 are reciprocated along the guide 29 by a lever 36 fixed to the bell-crank to grip the threads after the bill has made half a revolution. As the guide 30 is projected towards the end of the bill's second revolution, the guide 29 is pivoted about a pin 32 to strip the knot. This movement of the guide 29 is caused by a pin 37 on the lever engaging a spring catch 45 mounted on the guide support arm 31. At the end of the second revolution of the bill the catch is released and the guide 29 and clamps return to their initial positions to release the knotted threads. Specification 2311/03, [Class 112], is referred to.
