Title: Fluid braking systems
IPC: B60T13/58
Filed: 1964-12-18
Abstract: 1,018,600. Fluid-pressure brakes. WESTING- HOUSE BREMSEN-G.m.b.H. Dec. 18, 1964 [Dec. 20, 1963], No. 51528/64. Headings F2E and F2F. A trailable vehicle has manually operable means 2 which are operatively connected to brake-actuating mechanism 5, 6 and a fluid pressure motor 10 which is operable in dependence upon a variation of fluid pressure from a source on a tractor vehicle and is also operatively connected to the manually operable means 2. Normally an air pressure reservoir 17 charged from a source on the tractor vehicle pressurizes the left-hand chamber of the motor 10 while the same pressure from the source is communicated to the right-hand chamber by brake pipe 19, connection 20, and conduit 21. When the pressure in the brake pipe 19 is reduced on braking the tractor vehicle the piston 11 is caused to move to the right and so move the pedal 2 to operate the master cylinder 5, 6 to apply the brakes 9. When the tractor vehicle is disconnected the trailer brakes may be actuated directly by the pedal 2.

Filed: 1975-12-17
Abstract: 1516378 Ion-exchange CRANE CO 17 Dec 1975 [18 Dec 1974] 51694/75 Heading B1J A method of treating an anion-exchange resin bed which is contaminated by some cation-exchange resin (e.g. a bed incompletely separated from a mixed bed), and which has been regenerated by an alkali thereby converting the cation-exchange resin to alkalimetal type, comprises treating the regenerated bed with hydrazine to effect displacement of alkali metal from the cation-exchange resin, the hydrazine being in aqueous solution which after use is purified by being passed through a bed of hydrazine-type cation-exchange resin, whereby the purified hydrazine solution can be re-used. As described a mixed bed is backwashed which separates the two types of resin; the anion-exchange resin is removed to a separate regenerator and regenerated by aqueous caustic soda, then treated with aqueous hydrazine. The hydrazine solution thus acquires sodium ions from traces of cation-exchange resin present, and is treated with a hydrazinetype cation-exchange resin to remove these.

Abstract: 1486269 Variable-speed ratchet gear; linkwork TOBY ENTERPRISES Inc 3 Dec 1974 [26 Sept 1974] 52173/74 Headings F2D and F2K In a mechanism for converting continuous rotary motion of an input shaft into incremental rotary movements of adjustable magnitude of an output shaft, and suitable for operating the feed mechanism in a food slicing machine to control the thickness of slices, the input shaft (not shown) rotates a disc with an eccentric pin 22, Fig. 2, which, by a connecting link 23 oscillates a lever 31 about an axis 28 and, through a positive clutch 35, 38 when engaged, oscillates also a lever 62 which through a connecting link 66, Fig. 3, causes arcuate oscillation of one end of a link 68 the other end 93 of which has a pivotal connection with a one-way clutch 91. The motion of the link 68 is further controlled by a link 83, Fig. 2, of which one end is pivoted at the pin 65 which interconnects the links 66, 68 and the other end has a pivotal connection 82 with a lever 74 adjustable from outside by manual or mechanical means. As shown diagrammatically in Fig. 8, when the lever 74 is in one extreme position 74<SP>11</SP> of its adjustment range the pin 65 connecting together the three links 66, 68, 83 is constrained to describe an arc 114 as the link 66 swings the link 83 between positions 83, 8311 so that the link 68 is moved between positions 68, 68<SP>11</SP> and rotary increments corresponding to an arc 116 are imparted to the one-way clutch 91. These increments are reduced in magnitude and ultimately become zero, as the lever 74 is adjusted to move the pivotal connection 82 over the arc 112. The output shaft of the one-way clutch, which is acted on by a friction brake (not shown), drives a pair of output shafts 100, 105 through bevel gearing 103 and gears 104, 107. Engagement and disengagement of the clutch 35, 38 is controlled from outside by a carriage 47 slidable on guides 46 and having rollers 48 engaging a projection 40 on the lever 62.

Abstract: 1,197,480. Semi-conductor materials. R.C.A. CORPORATION. 22 Nov., 1967 [25 Nov., 1966], No. 53091/67. Heading H1K. The resistivity of a silicon layer on a monocrystalline alumina substrate is increased by heating the layer in contact with an ambient  into which excess aluminium atoms in the silicon layer diffuse. The ambient may be a solid, e.g. SiO 2  or Si 3 N 4 , a gas, e.g. flowing He, or a liquid. The aluminium atoms are present in the silicon layer due to diffusion from the alumina surface in the reducing conditions in which the silicon is deposited. In the embodiment, silicon is deposited on a sapphire substrate by reduction of silane, and a SiO 2  coating is formed thereon by oxidation in steam or oxygen, or by pyrolytic decomposition of siloxane. Alternatively, an oxide body may be formed separately and joined to the silicon layer by heating and pressing together. Some outdiffusion of aluminium into the oxide occurs during the oxide formation step. The temperature preferred for outdiffusion is in the range 800-1425‹ C.

A mooring and warping apparatus for a ship comprises a pair of winch drums 3 feeding a rope 4 to and from a storage drum 6 on which the rope can be wound in superimposed layers, the storage drum being driven by a variable output torque hydraulic motor 7 which is controlled to maintain a constant rope tension between the drums 3-6 by a mechanism adapted to sense the number of rope layers on the drum 6, or the tension in the rope between the storage and winch drums 6, 3. In the embodiment shown, the diameter of the outer rope layer on the storage drum 6 is sensed by a roller 18 which through a pivoted lever 19 controls the pressure of a spring 20 on a pressure relief valve 17 in the hydraulic supply line 14 from the motor 7, such that as the said diameter increases the motor 7 develops a greater torque since a higher hydraulic pressure is required to operate the relief valve 17. During paying-out of the rope 4, the motor 7 acts as a pump and hence a brake for the drum 6, the braking torque similarly varying the depencence on the number of rope layers on the drum 6. In another embodiment the valve 17 operating pressure is controlled in response to either the number of revolutions of the drum 6, or the direct tension in the rope 4 between the drums 6 and 3. In another embodiment the storage drum 6 is driven by an electric motor, the supply current of which is controlled in proportion to the outer diameter of the rope layers on the drum 6.
