Abstract: 584,282. Making cutlery. FLETCHER, G. H. Aug. 9, 1944, No. 15116. [Classes 83 (ii) and 83 (iv)] Welding.-Table and like cutlery of steel or non-ferrous metal is made by forming the blade, bolster and tang separately or the bolster and tang in one piece and the blade from a separate piece, the blade being formed from strip so as to be tapered transversely and if desired longitudinally, and then uniting the parts by fusion of metal and completing the article by grinding and polishing and applying the handle. Joining may be effected by electric flash welding or brazing. The blade of a knife may be of cutting steel, the bolster of a metal not having the same hardening qualities and the tang of carbon steel. The blade is formed from strip metal of tapered cross-section and may be formed with one or more longitudinal V-grooves so that two or more parallel blade blanks may be stamped from one strip. The blades may be cut diagonally from the strip so that the blade is tapered longitunally as well as transversely. The bolster may be forged with a short portion of blade to which the main blade is welded, and the tang is formed from round or other cross-section material formed with projections to provide keying means co-operating with the handle. The blade may be welded to the bolster and the bolster to the tang in separate Hash welding operations, or the three parts may be welded simultaneously by arranging them in series, the blade and tang being connected to the terminals of the electric circuit, or the bolster being connected to an intermediate tapping of a transformer and the two outer terminals respectively to the tang and blade.

Filed: 1959-05-04
Abstract: 887,118. Electric analogue calculating. ACF INDUSTRIES Inc. May 4, 1959 [May 6, 1958], No. 15145/59. Class 37. A minimum quantity selector comprises a constant alternating voltage source, plural variable amplitude analogue alternating voltage sources, difference means producing difference voltages equivalent to the difference between the constant voltage and each variable quantity voltage, half-wave rectifier means for allowing the passage of the largest difference voltage, and summing circuit means responsive to the largest difference voltage and the constant voltage whereby the resultant voltage is equivalent to the smallest variable quantity voltage. In Fig. 1, alternating input voltages C-X, C-Y, where C is a constant and X, Y are variables, are applied to the junctions 3, 6 of pairs of series assisting half-wave diodes 2, 4 and 5, 7, while a voltage -C in antiphase to C-X, C-Y is applied to the junction 9 of a pair of similar diodes 8, 10; the pairs of diodes being  connected in parallel over resistors 20, 24 to the input of a summation amplifier 28 having degenerative feed-back through opposed waveform correcting half-wave diodes 32, 34 and resistor 38. The greater of the voltages C-X, C-Y passes through the appropriate diode pair to junction 26 where it is combined with the antiphased voltage -C to develop a voltage -X or -Y which is phase-shifted 180 degrees in the amplifier 28 to an output voltage X or Y according as X < Y or Y <X and as C-X> or <C-Y. In a modification (Fig. 2) the input voltages are developed by applying voltages representing X and Y over summation resistances to feed-back amplifiers 58, 60 together with voltage -C 180 degrees out of phase therewith, to develop voltages C-X and C-Y applied to the diode pairs, where assuming Y)> X, diodes 2, 10 and 4, 8 conduct on alternate half-cycles to develop in succession voltages C-X and C on resistor 20 and antiphased voltages -C and - (C-X) on resistor 24 so that a voltage E o =X is developed at the output of amplifier 28. The device is applicable to computations of Boolean algebra, and a mathematical analysis is given. An application to the simulation of the transient response of a jet engine to throttle opening is described (Fig. 3, not shown), wherein the input voltages are derived from potentiometers fed with voltages representing input parameters and having sliders displaceable in accordance with other such parameters.

Title: Process and apparatus for the manufacture of titanium nitride
IPC: C01B21/076
Filed: 1963-04-19
Abstract: Titanium nitride is prepared either by mixing gaseous titanium tetrachloride in a mixing zone, whose walls are maintained at 136-500 DEG C., with ammonia, or a nitrogen-hydrogen mixture, heated at at least 1000 DEG  C. in an electric arc or by mixing gaseous titanium tetrachloride with a 1.2 to 20 times excess of hydrogen heated at at least 1000 DEG  C. in an electric arc and treating the formed titanium trichloride with ammonia in the mixing zone, in either case the reaction products being cooled and collected, preferably in an inert atmosphere. The ammonia or nitrogen-hydrogen mixture is used in 0.2 to 10 times excess and the molar ratio of N2 to H2 in the mixture is 1:6 to 1:3.  <FORM:1033553/C1/1> The titanium tetrachloride vapour may be introduced, preferably under pressure, e.g. 1.2 or 1.3 atmospheres, perpendicularly or tangentially to the flow of the ammonia, the nitrogen-hydrogen mixture or the hydrogen, which leave the arc at at least 200 m./sec., and mixing takes place within 1/10 to 1/1000 secs.  The reaction components are cooled on a moving surface maintained at 50-350 DEG  C. and the products deposited thereon removed continuously by a scraping means.  As shown, ammonia or nitrogen-hydrogen mixture introduced at 13 is preheated on passing through the arc between cathode 4 and anode 5, and, partially split into atoms or radicals, is mixed in channel 20 of mixing nozzle 6 seated in a recess of housing cover 3 with gaseous T1Cl4 supplied through 14 and annular slit 21.  The moving roller 1 is cooled by means of water or oil sprayed on to the segment nearest the burner from a perforated tube 7 disposed on the axis of the roller, and excess coolant 8 in the lower half of the roller leaves via an open cylinder at 9.  Solid reaction products adhering to the surface of the roller 1 and to the internal walls of the housing 2 are removed by a knife 17 rigidly connected to the housing 2, and by a pivoted knife 16 actuated, e.g. by a crank 15, and collected in 19.  Off gases, e.g. T1Cl4, HCl, NH4Cl and N2-H2 mixture, may be passed through a cyclone or baffle separator or a settling zone to collect entrained titanium nitride, and separated N2-H2 mixture and TiCl4 may be recycled.  The moving cooled surface may also be a rotating cone. In the modification illustrated in Fig. 4 (not shown), hydrogen is heated in the arc mixed with TiCl4, and the reaction product, mainly TiCl3 subsequently mixed with NH3. The reaction product is processed as before.  Alternatively, gradual cooling, e.g. in a sojourn zone may be employed. The product is freed of impurities, e.g. TiCl3 by washing with water or dilute HCl in the presence of an inert gas and filtering.

Patent GB-754357-A (GB)
Title: Improvements in or relating to a method of and apparatus for controlling the tools of machines for grinding and/or polishing glass
IPC: B24B7/24
Filed: 1954-05-26
Abstract: 754,357. Grinding or polishing glass. GLACERIES DE LA SAMBRE SOC. ANON. May 26, 1954 [May 27, 1953], No. 15616/54. Addition to 713,053. Class 60 The progressive adjustment of the pressures applied to the upper and lower tools of an apparatus for simultaneously grinding or polishing both faces of a horizontally moving glass sheet to compensate for the loss of weight due to the wear of the tools, as described in the parent Specification, is effected by utilizing the vertical movement of the tools to vary either the voltage applied to a pressure-compensating electromagnet or the degree of compression of a pressure-compensating spring. In Fig. 1, the upper tools 8 are rotated by a motor 14 and supported by a cross-member 7 which is in turn supported by hydraulic pressure acting on piston 6 and by a plunger 11 controlled by an electromagnet 1. The upward force exerted by the latter is decreased as the tools move downwardly due to wear by a variable resistor R2 the slider 10 of which is rotated by the plunger 11. The initial pressure applied to the tools is adjusted by a second variable resistor R1. An electromagnet 16 acts in a similar manner on a cross-member 18 for the lower tools 19 and may be arranged to apply either an increasing downward pressure or a decreasing upward pressure to that member. Safety abutments 13, 26 controlled by motors 12, 25 limit the movement of the members 7, 18. In a modification, the compensating adjustment of pressure is effected by connecting the electromagnet to a spring-loaded valve in the hydraulic supply line. In Fig. 3, upward pressure is applied to a cross-member 41 supporting tools 49 by springs 43 and by a pair of springs 65 arranged transversely of the cross-member. As the latter moves downwards due to the wear of the tools, a disc 44 supporting the lower ends of the springs moves downwards at the same rate so that the degree of compression of the springs 43 remains constant while the lower supports for the springs 65 move downwards at a higher rate thus allowing these latter springs to expand and reduce the upward pressure applied to the crossmember 41. The movement of the spring supports is effected either by screw and nut and toothed gearing operated by racks 53 mounted on the member 41 or by a motor receiving impulses as a function of the movement of the cross-member. A hand-wheel enables the initial pressure applied to the springs 43 to be adjusted. The cross-member 68 for the lower tools is urged upwardly by counter-weights 69 acting through racks 70 and toothed sectors and progressively compresses a spring 72 which thus applies an increasing downward pressure to the member 68 to compensate for the loss of weight of the tools.

Abstract: 792,177. Spring-coil valves. NATIONAL RESEARCH DEVELOPMENT CORPORATION. May 22, 1956 [May 31, 1955], No. 15646/55. Class 135. [Also in Group XXXIX] In an arrangement for modulating the flow of a fluid, a helix of resilient material is placed in the path of the flow so that fluid passes through the space between adjacent turns thereof, and means are provided for cyclically extending and contracting the helix in an axial direction. Compressed air in tube 2, of an electro-acoustic transducer, Fig. 1, passes through the convolutions of helix 1 and the helix is vibrated by a moving coil 3, in the gap of a pot magnet 4. In modifications described with reference to Figs. 2-6 (not shown) the air passage to or from the valve comprises a bore in the central pole-piece. In Fig. 3 the driving coil is mounted between two springs and in Fig. 4 the spring is driven by two moving coils between which it is mounted. Horn attachments are provided at the outlets in embodiments of Figs. 3, 5 and 6 and in the last two of these embodiments the compressed air is applied to the outside of the helix. In a concentric arrangement of two helical valves 1, 1<SP>1</SP>, Fig. 7, compressed air, which is supplied through a common equalizing chest, is modulated at a high frequency by the action of moving coil 3 on the inner helix and at a low frequency by the coil 31 acting on the outer helix. A modified arrangement for the same purpose is described with reference to Fig. 13 (not shown). The dimensions and material of the helix must be such that the speed of propagation of wave motion along the axis of the helix is substantially equal to the speed of propagation of pressure waves in the fluid, or alternatively, as in the embodiments described with reference to Figs. 8-12 (not shown), the individual turns of the helix may be driven electromagnetically either by placing them in a constant magnetic field and passing current through the helix or by constructing the helix of magnetic material and placing it in a field which may be varied. Deflecting members may be placed within the helix for directing the air flow and the fixed end of the helix may be mounted in sound-absorbent material to suppress reflection. The helix may be used to control the flow of liquids in, for example, a sub-aqueous signalling system.

Title: Improvements in and relating to the separation of particulate materials
IPC: B01J8/18
Filed: 1945-06-20
Abstract: <PICT:0600326/III/1> <PICT:0600326/III/2> A process for separating particulate material of desired particle size from a mixture containing material of larger particle size, which process may be used in the production of hydrogen as described in Specification 578,323, comprises passing a gas and/or vapour through a bed of the mixture contained in a stationary vessel with a conical bottom, at a velocity sufficient to maintain the material of desired size in the fluid state, avoiding the production of an entrained stream, but insufficient to prevent the larger particles from moving to the conical bottom of the vessel where they distribute the gas across the bed.  The velocity of the gas may, however, be increased at the upper surface of the bed for the purpose of removing the desired particle size in an entrained stream.  In the production of hydrogen, the mixture is metallic iron, iron oxide and larger particles due to agglomeration of the smaller particles.  In the arrangement shown in Fig. 1, the mixture is fed through a pipe 2 to a vessel 1 through which is forced a gas from a ring main 9 and tuyeres 10.  Larger material is removed from the bottom under the control of a slide valve 8. The smaller material is entrained through a pipe 3.  In a modification, the top of the vessel is conical, decreasing in cross-section to that of a narrow outlet.  In a further arrangement, the smaller material flows over a weir to an outlet. In the arrangement shown in Fig. 4, the smaller material flows through a channel 3 to an outlet pipe 15 where it is entrained upwardly by steam passed through a pipe 16.  Specification 582,055, [Group XII], also is referred to.
