Patent GB-947088-A (GB)
Title: Machine tool control system
IPC: G05B19/408
Filed: 1961-03-20
Abstract: 947,088. Numerical control systems. KEARNEY & TRECKER CORPORATION. March 20,1961 [May 13, 1960], No. 10029/61. Drawings to Specification. Heading G3N. The numerical control system for the drilling machine disclosed in Specification 874, 605 is modified in two respects. The machine still has the X, Y and Z tod movements and the interchangeable tools mounted in a rotatable turret, but the work is mounted on a single indexable table so only a single punched tape programme is required defining on 8 parallel tracks successive X, Y, Z and table index positions, choice of tool, tool speed, tool feed, and unspecified auxiliary functions. Secondly, pairs of storage registers (cross-bar switches) are inserted with each of the 8 channels, information from the tape being alternately fed serially into one of the pair whilst the other provides a parallel output to the channel concerned. Stepping switches advance the 6 digit addresses into the cross-bar switches, the appropriate levels being selected in accordance with the binary decimal coded input by binary/ decimal relay tree convertors. The outputs of the registers for the X, Y and Z axes control tappings on transformers providing A.C. analogue voltages for coarse, medium and fine selsyn positioning systems together with a linear resolver for the least significant digits. The outputs of the other registers operate as in Specification 874, 605. Specification 871,095 also is referred to.

Title: Control valves
IPC: F16K31/11
Filed: 1972-03-03
Abstract: 1417399 Valves HOTPOINT Ltd 2 March 1973 [3 March 1972] 10031/72 Heading F2V A valve for controlling the supply of gas to a burner has a valve head 4 locked in the open position by the engagement of balls 24 in a groove 31 when an electromagnet 29 is energized by a thermocouple when the burner is alight. The valve head, which includes a sealing ring 9 engaging a seat 11 in the closed position of the valve, is moved to the open position by depressing a spring loaded button 8. The button is held depressed until the burner is alight and the electromagnet energized. The valve head comprises a cup-shaped member 14 having a number of U-shaped slots in which the balls 24 are held captive by an annular plate 16, itself made captive by the turnedover heads of lugs 15. Within the valve head is held captive a tapered member 17 to the top of which is attached an annular ferromagnetic armature 19. A spring 23, located in a groove 22 of member 17, urges the sloping face 27 away from the plate 16 to permit the balls to ride up it when the valve is being opened. When the burner is alight and the button is released, the armature is held by the electromagnet but plate 16 moves under the influence of spring 13, which is stronger than spring 23, to force the balls outward to engage the groove and lock the valve in the open position. If the burner goes out and the electromagnet is deenergized, the armature is released and member 17 moves downwards under the influence of spring 23 permitting the balls to ride out of the groove as the head moves to close the valve under the influence of spring 13. The position of the button may be used as a visual indication that the valve is open and the burner is alight.

Title: The manufacture of polyoxyalkylene glycols and their mono-ethers
Filed: 1952-04-25
Abstract: Polyoxyalkylene glycols or mono-ethers thereof containing at least 4 oxypropylene units in the molecule and having molecular weights up to 4000 are formed by continuously passing a homogeneous mixture of 1,2-propylene oxide with or without ethylene oxide, an organic hydroxy compound and an alkali metal catalyst through a reaction zone maintained by removal of heat of reaction at 50-190 DEG  C. under a pressure sufficient to maintain the mixture liquid, e.g. 7-130 atmospheres, the contact time in the reaction zone being 5-60 minutes and 25-97 per cent of the alkylene oxides being reacted.  Suitable hydroxy compounds are: glycols, e.g. ethylene, propylene, polyoxyethylene or polyoxypropylene glycol, 2,21-thiodiethanol; monohydric alcohols having up to 20 carbon atoms/molecule, e.g. n-butyl, lauryl or benzyl alcohol or 2-ethyl hexanol or mono-ethers of glycols with one of their monohydric alcohols; mono- or di-hydric phenols or naphthols, e.g. phenol, b -naphthol, cresol, octyl phenol or octyl cresol.  Initial heating of reactants and cooling during the reaction are preferably provided by surrounding the reactor with a boiling liquid, e.g. blends of water with ethylene glycol or ethylene glycol monobutyl ether.  Suitable alkali metal catalysts are sodium, potassium or lithium generally dissolved as the hydroxide or alkoxide in the hydroxy compound.  Preferred catalyst concentrations are 0.0005-0.4 gm. mols./litre of reactants.  The oxides used in the process may be dried and freed from aldehyde or acid impurities by passage through a bed of solid caustic soda or potash.  In carrying out the invention the aqueous alkaline catalyst was dissolved in the hydroxy compound, water distilled off and the material cooled.  The alkylene oxide and alkali-containing hydroxy compound were separately pumped in desired proportions by pumps 11, 12 from supply lines 13, 14 to a mixer 17, and through a stainless steel reactor coil 19 immersed in boiling liquid 21 in a vessel 20.  The reacted liquids pass through pipe 25 to needle let-down valve 26, and pipe 27 to still 28.  Unreacted oxides are recycled by pipe 32 and the reaction product is pumped by pump 29 to cooler 31 and thence to storage. Examples describe the conditions used in the reaction of diethylene glycol with mixed ethylene and propylene oxides, of dipropylene glycol with propylene oxide, of n-butanol with propylene oxide, of ethylene glycol monomethyl ether with propylene oxide and of polyoxyethylene glycol with propylene oxide.  In other examples polyoxypropylene glycol is reacted with mixed ethylene and propylene oxides.  The Specification describes the structure, molecular weights and physical properties of a number of the products obtained according to the invention. Products useful as heat-sensitizers for rubber, as lubricants, or as hydraulic brake fluids.  Specifications 601,419, [Group IV (b)], 610,505 and 736,991 are referred to.

Abstract: 476,484. Making wire and like couplings ; change speed gear. TONDEUR, R., and BOWDEN (ENGINEERS), Ltd. April 9, 1936, No. 10581. [Classes 83 (ii) and 83 (iv)] [Also in Group XXIV] Welding ; dividing by fusion.-A flexible stranded wire cable, such as the inner member of a push-and-pull Bowden mechanism, has rodlike pieces attached to the ends thereof by fusing the ends of the cable to produce solid ends and then welding thereto rod-like pieces of substantially the same diameter as that of the cable. The fusing may be effected by fixing the cable in copper electrodes and resistance heating till the cable is severed by melting, the cable being preferably under tension during the operation. The ends may be faced by grinding, prior to welding. The rods may be welded to the cable ends by electric resistance, flash or percussive welding. In the flash welding operation a supplementary magnetic-circuit may be broken when the welding pressure is applied so that a further current is discharged to heat the ends further. The end of the rod-like pieces may be pointed or drilled so as to increase their electric resistance. When the cable forms the inner member of a flexible shaft drive it may be previously hardened by heat treatment. In a push-and-pull Bowden mechanism acting as an operating device for the selector mechanism of a change-speed gear-box for motor cars and having two Bowden transmissions 1, 2, the ends 7 and 8 welded as aforesaid to the cables 3, which operate respectively the first and reverse gear and the second and third gears, pass through casings 4 positively anchored at each end to stops 5 and 6. Eye pieces 9 are screwed on the extensions 7 and cylindrical nuts 11, 12 with peripheral grooves are screwed on the extensions 8. The operating rod 15 is provided with longitudinal grooves on opposite sides engaging lugs 19, 20 on a stop disc 21, which is mounted in recesses 22, 23 in the housing 14. The rod is also provided with a notch 26 engaging a spring-pressed, ball 27 when in neutral position. When the rod is rotated to the right, a tongue 28 on the disc 21 engages the groove in the nut 12 to prevent axial motion of the cable in mechanism 2, and the cable of mechanism 1 may then be operated by longitudinal motion of the rod, which is provided with a projecting lug 25. When the rod is rotated from neutral position in the opposite direction, the tongue 29 engages the groove in nut 11 and the nut 12 is freed for operation by the lug 25. The casing 4 may consist of tubing as described in Specification 412,367, [Group XXIV], consisting preferably of four to eight coils.
