Patent GB-1042140-A (GB)
Title: Improvements in or relating to pulse train generators
Inventor: MARWOOD CHARLES TIMOTHY
IPC: H02P23/00
Filed: 1962-11-12
Abstract: 1,042,140. Automatic speed control. DE HAVILLAND AIRCRAFT CO. Ltd. Nov. 12, 1963 [Nov. 12, 1962], No. 42659/62. Heading G3R. [Also in Division G4] In a multiple pulse train generator, a pulse train is fed simultaneously to a plurality of gates connected in a ring, the gates being enabled sequentially in either direction around the ring by energization of one of two pairs of inputs 8, 9 or 10, 11 (not shown) of each gate in turn. A pulse from a pulse generator, on being passed by one of the gates switches to 1 and associated bi-stable device. One of two lines 12, 13 (not shown) is kept energized to control the direction of cycling of the ring,being connected to inputs 8, 10 (not shown) respectively of the gates. The outputs of the bistable devices control the inputs 9,11 (not shown) of the gates and also control second inputs to the bi-stable devices to ensure only one device holds 1 at a time. The pulse train outputs of the bi-stable devices are amplified and drive a stepping motor which controls a valve in the fuel supply to an engine. The engine speed is compared with a datum value to produce a difference signal, the magnitude of which determines the frequency of the pulse generator and the polarity of which determines which of the two lines 12,13 (not shown) is energized. The engine speed is thus brought towards its required value, until the difference falls below a threshold value when a device prevents further pulses from the generator from reaching the gates. The datum value and the threshold value may depend on engine temperature.

Title: Method of making Fluted Drills and the like
IPC: B23B51/06
Filed: 1967-09-19
Abstract: 1,151,166. Making drills, taps and reamers, cutting tools. KOBE STEEL Ltd. 19 Sept., 1967 [3 Oct., 1966], No. 42695/67. Headings B3A, B3C and B3N. A method of making drills, taps and reamers, having oil passages therein comprises boring at least two holes 2 of larger cross-section than required in the finished drill &c., in a stock material of larger cross-section than the finished drill &c., heating the stock material and elongating it to reduce it to the diameter of the finished drill &c., and thereafter giving the elongated stock material its desired finished form. The holes 2 in the billet 1 may be filled with a heat resisting powder or granular medium 3 such as hard carbon and alumina and then sealed. The heated billet is then either forged by a press, hammer or swager or rolled to reduce it to the drill diameter. The seals are removed or the end of the stock material cut or turned off, to take out the medium 3. The flutes 6 are formed and the material twisted by any known method to provide the final product. In an alternative method, a number of bored lengths of stock material are welded end to end prior to being reduced in diameter, the elongated stock then being cut to the required lengths. In a further method, the terminal ends of the holes are interconnected by a transverse hole (23), copper wires being inserted in all the holes, which are then sealed by plugs (26), (27), Fig. 3 (not shown). The portion of the bar containing the holes is dipped in a salt bath to heat it to about 1000‹ C., whereupon it is extruded in a twist die. It is then hardened at about 1220‹ C., the copper wires melting and flowing out. Finally, it is turned and ground.

Title: Roof for metallurgical furnaces
IPC: F23M5/06
Filed: 1959-12-16
Abstract: 893,887. Suspended furnace roofs. VEITSCHER MAGNESITWERKE A.G. Dec. 16, 1959 [Dec. 22, 1958], No. 42847/59. Class 51 (2). In a suspended roof for a metallurgical furnace the specific surface pressure between individual bricks is preserved at an approximately constant low value in order to lengthen the life of said roof. The arch bricks 1 are suspended from supports 5 carried by hangers 8 and 9 engaging transverse members 11 with the intervention of springs 10, the tension of which is adjusted by nuts 12. The arch is also supported by a fixed skew-back 2 and a resilient skew-back 4 subject to an adjustable tension by spring 3. As the roof wears and loses weight it rises slightly, decreasing the lateral compressive force exerted by the skewback. The invention is also applied to a flat arch, Fig. 2 (not shown).

Title: Improvements in and relating to the treatment of metals
Inventor: GRENFELL HUGH WILLMOTT
IPC: C22B9/05
Filed: 1966-09-26
Abstract: 1,148,602. Refining metals. STEEL CO. OF WALES Ltd. Sept.20, 1967 [Sept.26, 1966; Feb. 13, 1967], Nos.42900/66 and 6709/67. Heading C7D. Metals are treated and in particular refined by producing in the vessel a flame formed by oxygen and a liquid carbonaceous fuel, particles of solid material being entrained in the fuel supply. The process is particularly applicable to the refining of iron, copper or zinc, while the solid particles may be lime, iron ore, scale, fluorspar, calcium carbide or carbonaceous material, may constitute 30% to 50% by weight of the fuel, and preferably have a particle size less than # ''. Advantageously there may be an excess of oxygen supplied over that required for complete combustion of the fuel, the excess possibly being more than 100% of that so required. When the process is applied to the refining of iron the lime addition may be such that during the first two-thirds of the blow the slag basicity is about 1, additional lime being added during the final third of the blow to give a final basicity of 1À4-1À8.
Patent GB-989521-A (GB)
Title: Microcellular polymer sheets and production thereof
IPC: B29C48/76
Filed: 1962-11-14
Abstract: A microcellular sheet is made of a synthetic crystalline organic polymer in which substantially all the polymer is present as cell walls of thick ness less than 2m  but preferably less than 0.5m . Such a polymer may be a polyhydrocarbon, e.g. linear polyethylene, polypropylene or a copolymer of ethylene and a minor proportion of an a -olefin containing 3-10 C atoms, e.g. 1-octene. A sheet may be formed by bonding 2 sheets together in which the machine directions are at an angle of at least 30 degrees to each other and may also incorporate potassium titanate and fibrous reinforcing elements.  The process for producing such a sheet comprises extruding, e.g. through a slot or annular orifice, into a region of lower pressure and temperature a solution of the synthetic crystalline polymer in a liquid of b.p. at least 25 DEG  C. below the m.p. of the polymer, at such a temperature that the adiabatic evaporation of the liquid produces cooling and precipitation of the solid polymer.  The temperature of the solution is above its f.p. and the concentration of the liquid is between 98% and that adequate to produce precipitation of the polymer. The liquid is a solvent for the polymer under the conditions of the extrusion but dissolves less than 1% of the polymer at its normal b.p.  The liquid may be a hydrocarbon or halogenated hydrocarbon, e.g. CH2Cl2, pentane, CCIF3 but also mentioned are C2H5Cl, butane and ethanol.  Other additives for foaming may be N2, CO2, He, H2, CH4, C2H6, C3H8, C2H4, C3H6 and fluorinated and/or chlorinated methanes and ethanes.  Alternatively a particulate solid nucleating agent may be used if the solution is extruded below the autogenous pressure necessary to produce enough bubble nuclei at the instant of extrusion.  A silica aerogel may also be added.  The extruded sheet may be compressed beyond its yield point to a thickness of less than 1/3 of its extruded thickness, preferably at a temperature below the crystalline m.p. of the polymer to give a paper-like sheet.  Polymers mentioned in addition to the above are polystyrene, polyesthers, e.g. polyformaldehyde, vinyl polymers, e.g. polyvinylidene fluoride, polyamides (aliphatic and aromatic) e.g. polyhexamethylene adipamide and polymetaphenylene isophthalamide, polyurethane (aliphatic and aromatic) e.g. that from ethylene bischloroformate and ethylene diamine, polyesters, e.g. polyhydroxypivalic acid and polyethylene terephthalate, with/without isophthalate and mixed polymers, e.g. poly-ethylene and poly-propylene. Common polymer additives of specified types may be added.

Title: Temperature-responsive electrical control system
Inventor: HASSEN TORE BERSET
IPC: G05D23/24
Filed: 1959-12-23
Abstract: 910,150. Automatic temperature control. KING-SEELEY THERMOS CO. Dec. 23, 1959, No. 43794/59. Class 38 (4). In an automatic temperature-control system, a coil 44 of a pulsing relay 10, having bi-metallic legs 30, 32 joined by a rigid crosspiece 36, is connected in series with contacts 40, 42 and a temperature-responsive resistor 12, sensing the temperature of a body, across the secondary of a step-down transformer 22 so that the contacts 40, 42 are opened and closed at a rate dependent on the temperature of the body. A responder relay 14 of similar construction to the pulsing relay has a coil 100 energized through the pulsed contacts 40, 42 so that contacts 122, 124 are opened and shut at a rate dependent on the average electrical energy fed to the coil 100. Contacts 122, 124 control the current through a wire 150 of a hot-wire relay 16 so that the energization of a heater 18 through contacts 180 182 is varied so as to maintain the temperature of the body constant. A coil 51 of the pulsing relay 10 is energized in series with the hot-wire 150 so as to increase the energization of the responder relay coil 100 when the temperature of the body is below the desired value. The controlled temperature is adjusted by a screw 138 varying the relative position of contact 124 with respect to contact 122 or as in a modification by switched resistors inserted in a line 60. The temperature-responsive resistor may comprise a wire element or a thermistor and can be contained in a spring-loaded cap disposed within a central aperture of a stove surface-heating electrical element. A permanent magnet surrounding the contact 124 and co-operating with an armature 120 gives a " snap-action " to the operation of contacts 122, 124. Specification 43,203/59 is referred to.
