Title: Improvements relating to hydraulic motion-transmitting systems
IPC: F16H43/00
Filed: 1957-07-01
Abstract: 818,889. Telemotor systems. GLEASON WORKS. July 1, 1957 [July 2, 1956], No. 4683/59. Divided out of 818,888, [Group XXII]. Class 69 (2). An hydraulic system comprises a transmitter 1 connected by lines 13, 14 to a receiver 16. The displacement of the receiver is greater than that of the transmitter, and at the end of a stroke of the transmitter piston 2 a reduced portion of the piston-rod opens a port 5 which is connected to a pump 7, and the stroke of the receiver piston 15 is completed by liquid supplied by the pump. Liquid displaced from the exhaust side of piston 15 during this terminal, portion of the stroke passes through a port 17 which is uncovered by piston 2 in its end position, and through a relief valve 18 to exhaust. Back pressure maintained by valve 18 serves to check the stroke of piston 15. At the end of its stroke piston 15 uncovers a port 19 or 20 and liquid from the pump passes through this port and a relief valve 21 to exhaust. The exhaust flow through valves 18, 21 at the end of each stroke keeps the system full of liquid and free from air. The transmitter piston is reciprocated by a grooved cam 3, and the receiver piston oscillates an output pinion 23 which may operate the gear-cutting machine index mechanism disclosed in Specification 818,888.

Title: Improvements in the coating of fluorinated polymers
IPC: C23C18/20
Filed: 1958-02-13
Abstract: Polyfluoroethylene surfaces are metallized by contacting them with a solution of an alkali metal in a non-metallic inert solvent and then depositing finely-divided metal thereon.  The alkali metal may be sodium or lithium; the solvent may be liquid ammonia, a low molecular-weight amine, or pyridine; and the coating metal, e.g. aluminium, copper, silver, chromium, nickel, geranium or tin, may be deposited by reduction of a dissolved saft or by vacuum evaporation. The process may be used for coating polyfluoroethylene-insulated wires, in making printed or inlaid circuits, and in producing capacitor electrodes.  Further the metallized surfaces may be electroplated, or conductors soldered thereto.

Title: Improvements in and relating to Magnetic Chucks.
Inventor: BLACKALL FREDERICK STEELE
IPC: B23Q3/154
Filed: 1919-02-26
Abstract: 123,983. Blackall, F. S., (Assignee of Simmons. F. L.). Feb. 26, 1918, [Convention date]. Electro-magnetic chucks and work-holders.-A magnetic chuck is built up of a number of magnetic units each comprising (a) a mild-steel core part, Fig. 4, consisting of a base-plate 2 carrying preferably eight vertical webs 5 around which the energizing-coils 20, Fig. 3, are fitted, and (b) corresponding pole-pieces, shown in perspective in Fig. 6, and in end view in Fig. 9. A non-magnetic housing 8, Fig. 3, preferably of aluminium, is cast around the core-part and solid with the base-plate 2, so as to form a box-like base for the chuck. Similarly, eight of the pole-pieces shown in Fig. 6 are placed side by side so that the lateral projections 14 and recesses interfit, but with clearance, and the whole is cast solid with aluminium 15, Fig. 3, so as to form a species of lid for the box-like base. The two castings are then machined and the pole-pieces fitted over the core part, so that the webs 17 make good contact to the webs 5. The whole is then bolted together with bolts 10, a thin gasket of paper &c. being inserted around the side walls so as to make a wax-tight joint. The energizing-coils on adjacent cores are wound in opposite directions, so that the pole-pieces are alternately north and south. This arrangement of casting with non- magnetic metal increases the efficient flux density of the chuck face-plate bv reducing leakage through the work-holder and tool, and at the same time gives a rigid support for the chuck, which is clamped to the machine frame by the flange 7, Fig. 3. A distance-piece for positioning the work is fastened to the edge of the face-plate, and a back-rest 26 is also provided. By means of a switch, the windings may all be placed in series or half of them may be in parallel., according to the voltage available. Alternate forms of interlocking pole-pieces are shown, bv the use of which the whole face-plate can be built up with polepieces drop-forged from only two dies.

Title: Improvements in coating metal containers
IPC: C09D5/44
Filed: 1937-02-18
Abstract: 490,851. Coating metals by electrophoretic deposition. CROSSE & BLACKWELL, Ltd., CLAYTON, W., JOHNSON, R. I., and SUMNER, C. G. feb. 18, 1937, Nos. 4909/37 and 2212/38. [Class 41] Metals, particularly the inner surfaces of metal containers for beverages or parts thereof, are coated by electrophoretic deposition of wax or a waxy material from an aqueous dispersion, the deposit being subjected to such a temperature that the particles coalesce to form a continuous coating. The material deposited may consist of beeswax, ceresin, paraffin wax or compositions containing them. In order to increase the " throwing power " the dispersion medium should include a salt of alkaline reaction having an anion such that addition of acid would produce an insoluble oxide or hydroxide, e.g. sodium silicate or sodium aluminate or mixtures thereof. The composition of the bath should be so chosen as to avoid precipitation by acidic constituents of the waxy material, The alkalinity should be only slightly greater than that necessary to produce stability. The conditions be so adjusted that on passage of current an oxide or hydroxide is deposited at the anode with the wax particles. The initial resistance of the circuit should be low so as to produce a high initial current density which falls rapidly as the wax film builds up, this conducing to uniformity of thickness; the effect may be assisted by progressively introducing resistance into the circuit. After coating, the surface is freed from excess of the dispersion by draining or rinsing ; the dispersion may be of low viscosity to facilitate draining. The deposit is then dried by warm air and heated above the melting point to render it coherent, adherent and impermeable. Electrodeposition may be effected at room temperature or above the melting point of the wax. By addition of known reagents to the dispersion deposition may be caused to take place on the cathode instead of the anode.

Title: Mechanical control device for a brake mechanism
IPC: F16D65/56
Filed: 1975-02-05
Abstract: 1455536 Disc-brake actuators; slack-adjusters SOC ANON DBA 5 Feb 1975 [27 Feb 1974] 4944/75 Heading F2E  A mechanical brake actuator comprises first and second extensible members 28, 32 connected by screw-threading 30; a piston 20 acting on the friction member 22 and connected to the second extensible member 32 by a spring 50 which permits relative movement between piston and extensible member in one direction of rotation ; and a wear adjusting element 58 normally connected to member 28 by a one-way transmission which enables element 58 to turn relative to member 28 through an angle corresponding to the wear on the friction member on brake application and causes the second extensible member 32 to turn through said angle and so advance relative to member 28 on brake release. As shown, the wear adjusting element 58 engages element 28 through one-way teeth 60, 62 urged with engagement by spring and has arcuate slots 68 (Fig. 2) which receive rods 70 extending through member 32. Member 28 is rotated clockwise by lever 34 to apply the brake, relative rotation of member 28 and element 58 occurring when the degree of rotation slots 68 engage rods 70. When lever 34 is released teeth 60, 62 cause member 28 and element 58 to rotate together so that when the ends of apertures 68 again abut rods 70 element 58 tends to entrain extensible member 32 and rotate it relative to piston 20, spring 48 permitting this rotation. Member 32 is therefore extended relative to member 28. The actuator is re-set, to permit replacement of the friction member, by withdrawing a plunger 78 so that spring 88 can, via a flange 84 on sleeve 76, urge element 58 away from member 28; lever 34 can then be rotated anti-clockwise until the parts reassume their initial position. In the embodiment of Figs. 4 and 5 (not shown), the one-way transmission is located on the end of the member 28 remote from the lever 34 and relative rotation of the wear adjusting element and member 28 is caused by a tongue and groove arrangement.
