Title: Improvements in or relating to copying attachments for lathes or like machines
Inventor: JONES GLYN CEIRIOG WALTERS
IPC: B60T8/18
Filed: 1958-03-08
Abstract: 848,523. Copy turning. MYFORD ENGINEERING CO. Ltd. March 5, 1959 [March 8, 1958], No. 7516/58. Class 83(3). A lathe copying attachment comprises a plate 1, Fig. 1, attached to the machine slide 2, a tool slide 3 mounted movably thereon, and an hydraulic cylinder block 8 secured to the slide 3, with a piston 6 slidable therein and secured to the plate 1 by a rod 5. Ports 10, 11, Fig. 4, in the cylinder are connecte d to a valve chamber 14 in the block 8 by passages 12, 27, and 13, 28, respectively. A disc valve 15, Fig. 5, having apertures 20, 21, for connecting the ports 10, 11, to the passages 12, 27, and 13, 38, is rotatably mounted on a hollow pillar 16, which is connected to an oil pressure supply 17, and has apertures 18, 19, which connect with the apertures 20, 21, in the valve. A third aperture 29 in valve 15 communicates with an exhaust passage 30. The valve 15 is actuated by a stylus 32, against a spring plunger 33. In operation, the stylus 32 is held against a template 34, Fig. 5, by a spring plunger 33, and if the stylus is moved to the right by the template, during axial traverse of the saddle 2, the disc valve 15 is rotated counter-clockwise by a pin 35 on the stylus, and communication is made between the aperture 21 and the ports 24, 26, thus allowing oil to flow through passages 13, 28, to port 11 to move cylinder block 8 and the tool slide 3 to the right, the port 10 being connected to exhaust by passages 12, 25, 27, and 29. If movement of the stylus ceases, the valve is returned to its original position by the movement of the block 8. When the stylus moves to the left, the disc valve is rotated by the plunger 33, and the port 10 is supplied with oil under pressure, thus moving the tool slide 3 to the left. Due to the oil being supplied to both sides of the valve 15, side thrust on the valve is reduced.

Patent GB-767558-A (GB)
Title: A method of and device for ascertaining breaks in multi-wire strands
IPC: G01R31/02
Filed: 1955-03-16
Abstract: 767,558. Continuity testing. VIERLING, O. March 16, 1955 [March 16, 1954], No. 7638/55. Class 37. In an apparatus for testing multi-strand cables with respect to individual broken strands therein, the cable to be tested is inserted in a circuit fed by a voltage free of harmonics and is mechanically moved so that the current pulses due to intermittent contact of the ends of the broken strands are amplified and supplied to a measuring instrument, the deflection of which is an indication of the number of broken strands. In one embodiment, Fig. 1 (not shown), the cable is connected by a switch in series with the primary winding of a transformer and a battery. Any impulses in the secondary circuit are amplified, rectified and fed to a meter. In another arrangement, Fig. 2 (not shown), voltage pulses are developed across a resistor and a differential meter is used. In another arrangement, Fig. 3, the cable is connected in series with the filament heating circuit and also in the grid circuit of an amplifier, the last tube of which has a meter in its anode circuit and is biased by rectified impulses, if any. In Fig. 4 (not shown), the pulses are developed across a relay which switches on the amplifier filaments. In a modification, Fig. 5, when the cable is plugged in to points 17, 18, relay 20 connects battery 19 to transistors PNP, which amplify pulses developed in a transformer 2, and apply them to a meter 6 in such a direction as to reduce the deflection. The meter in this case is short-circuited except when the cable is plugged in. The test set has an additional socket for the connection of a battery-charging plug.

Title: Improvements in motor speed responsive arrangement for controlling motor winding circuits
IPC: H01H13/64
Filed: 1966-02-22
Abstract: 1,143,184. Speed-responsive switches. GENERAL ELECTRIC CO. 22 Feb., 1966 [24 Feb., 1965], No. 7689/66. Heading H1N. The subject-matter of this Specification is substantially the same as that described in Specification 1,140,689, but the claims are concerned with the biasing of the speedresponsive member to avoid hunting. A switch 30, as described in Specification 1,140,689, is connected to the starting winding 28 (as in Fig. 2, not shown) of an induction motor 20 and has an operating plunger 84 which is restrained in its starting condition, against internal spring force, by arm 83 of a cranked lever pivoted through aperture 82 in the motor end-plate 22. Birfurcated end 79 of this lever straddles motor shaft 24 and engages an axially movable collar 38 which is urged to the right by two hookshaped centrifugal members 39, drawn together by springs 42. The members 39 slidingly engage the edges of notches in a plate 41, secured to the rotor 26, whereby the force urging collar 38 to the right has a maximum value when the collar 38 is in a position close to its standstill position. As the motor speeds up the members 39 move outwards and collar 38 moves to the left, but the arrangement is such that the rate of decrease in the force exerted by the switch 30 is less than the rate of decrease of the force exerted by springs 42 after the collar 38 has moved beyond the maximum value position; hence the collar 38 then moves positively towards its running position without requiring a speed increase beyond that speed causing movement from its standstill position to the maximum value position. Thus subsequent normal speed changes do not result in recycling of the starting switch. In a modification (Figs. 14 to 17, not shown) the switch and circuitry are adapted to a multi-speed induction motor having separate high- and low-speed running windings and a starting winding.

Patent GB-581947-A (GB)
Title: Improvements in or relating to the treatment of fibres, filaments, threads, yarns, fabrics and like materials having a basis of an organic ester of cellulose
IPC: D06M11/38
Filed: 1944-04-28
Abstract: Filaments, fibres, threads, yarns, fabrics and like materials consisting of or containing cellulose acetate or other organic ester of cellulose are substantially completely saponified by an aqueous medium containing sodium hydroxide in a concentration of from 0.6 to 1 per cent by weight and an inorganic salt which has an inhibiting effect on the swelling action of the saponifying medium for the cellulose ester.  Specified inorganic salts are the sulphates of sodium and potassium.  The saponification may be effected on materials having a basis of, for example, cellulose acetate, propionate, butyrate, aceto-propionate or acetobutyrate, and the process is applicable to stretched yarns of such material.  The process substantially minimizes the comparative reduction in breaking strength of the materials which usually occurs on saponification.  To the saponifying bath containing sodium hydroxide and sodium sulphate, other soluble salts, e.g. sodium chloride, sodium acetate or potassium acetate may be added.  Numerous examples are given, in one of which cellulose acetate yarn is immersed in a saponification bath comprising an aqueous solution of sodium hydroxide containing sodium sulphate and sodium acetate at 80 DEG  C.  The yarn is then removed, washed and dried.  Specification 150,989, [Class 15 (ii)], is referred to.  The Specification as open to inspection under Sect. 91 comprises also the saponification treatment as applied to fabrics containing a mixture of cellulose acetate and other textile materials such as silk, cotton, or regenerated cellulose and the treatment may be local.  Other saponifying agents such as potassium hydroxide, sodium or potassium carbonate or silicate, sodium sulphite and trisodium phosphase are also specified.  This subject-matter does not appear in the Specification as accepted.

Title: Improvements in methods and apparatus for blasting
IPC: F42D1/00
Filed: 1959-03-10
Abstract: 865,554. Fluid-pressure blasting apparatus. UNION CARBIDE CORPORATION. March 10, 1959 [March 28, 1958], No. 8161/59. Class 9(1). Fluid-pressure operated blasting apparatus comprises a storage container 13, fed with liquid gas, e.g. nitrogen, through an inlet 11 controlled by a valve 12, and a high-pressure pump 14, which delivers the gas through a heat-exchanger 20 to gas receivers 28, whence the gas is conveyed to cartridges 44 inserted in holes drilled in the working face. The liquid gas enters the container 13 at a low pressure e.g. 0-5 lb./sq. in. and is supercooled to perhaps 12‹ C. below saturation by withdrawing liquid through a pressurizing conduit 13c and'returning it to the container. The pump 14 builds up a pressure in the liquid gas of say 3,500 to 20,000 1b./sq. in. and drives it through a cylinder 17, where pressure variations are damped out before the liquid enters the coil 19 of the heat exchanger. Preferably the cylinder 17 is arranged with its axis vertical and the inlet and outlet at the lower end, so that a compressible gas phase exists at the top of the cylinder to damp out pressure fluctuations. The coil 19 is surrounded by water in which is immersed an electric heater 21 controlled by a thermostat 25. The water bath may be omitted, in which case the coil 19 is air heated being provided with extended heat exchange surfaces. The heated gas passes into the receivers 28 at a temperature between 0‹ C. and 20‹ C., the pressure in the receiver being used to operate a switch 29 controlling the motor 33, which drives the pump 14. By operating a control system 38, a valve 37 is opened to supply gas to a conduit 43 leading to cartridge 44. The control system includes a regulating valve 39, a blow-down valve 41 and a pressure gauge 42, the valve 41 being used to depressurize partially charged cartridges. The cartridges may have pressure release means in the form of a rupturable disc or a valve which vents at a given pressure. The apparatus may be mounted on a wheeled vehicle.
