Title: Plated flush pattern or circuitry laminates and production thereof
IPC: H05K3/38
Filed: 1959-03-16
Abstract: 877,824. Laminates. ST REGIS PAPER CO. March 16, 1959 [June 24, 1958], No. 9064/59. Addition to 822,826. Drawings to Specification. Class 140. [Also in Groups XV and XXXVI] The method of the parent Specification is modified by plating one or more surface metals on to the pattern areas of thin sheet metal before the laminating procedure. In one embodiment, a thin sheet of metal, provided on one side with an insulating film is printed on the other side with a resist, leaving the pattern areas exposed, a metal is plated, e.g. electroplated, on to these areas, the resist is removed and the unplated metal etched away. The product is then laminated as in the parent case. An apparatus for this method is described; it is generally similar to that described in the parent Specification but has an additional bath for the electro-plating. In an alternative embodiment, the metal sheet is provided with an insulating film, resist-printed, etched, and the resist removed as in the parent case, and the pattern areas then plated. If the desired pattern areas are not electrically continuous, the resist printing may define the pattern areas and connecting lines therebetween, which may be removed after the plating step, e.g. by punching out from the sheet after plating, or from the finished laminate after consolidation. Alternatively, the foil is printed with etching resist to define the desired pattern and connecting lines, the background removed by etching, and the etching resist washed off; the connecting lines are then printed with a plating resist, the plating carried out, the plating resist removed and the connecting lines etched away in a bath that will not attack the surface metal. The surface metal may be rhodium, nickel, gold, silver or a solder metal; rhodium may be plated on to a first plating of nickel on copper. Specifications 639,111 and 639,178 also are referred to.
Patent GB-417996-A (GB)
Title: Process of refining fatty oils
IPC: C11B3/06
Filed: 1933-03-25
Abstract: Raw fatty oils are refined by injecting an aqueous solution of a refining agent such as caustic soda or sodium carbonate into a flowing stream of the oil so as to disperse the reagent uniformly in the oil as fine drops, maintaining this mixture in a flowing stream until the impurities in the oil are neutralized or rendered capable of subsequent removal, maintaining the oil with the foots produced suspended therein in a flowing stream which is subjected to <PICT:0417996/III/1> mild turbulence for a period sufficient to produce an agglomeration of the foots and finally separating the oil from the foots by centrifugal treatment.  Higher temperatures than usual may be used in the refining and decolourization may be produced simultaneously.  In the example given raw cottonseed oil is fed by a pump 12 through pipes 18, 20 and a heater 3 to a mixer 4 to which an aqueous solution of caustic soda is simultaneously supplied by a pump 11 through pipes 17, 19, and a heater 2.  The pump 12 is driven by a shaft 13 which also drives the pump 11 through shaft 14 and a variable speed gear 15 which can be operated by a lever 16 to control the proportions of oil and caustic soda supplied to the mixer 4.  The liquids pass in the heaters 2, 3 through pipe coils 22, 32 which are enclosed in shells 21, 31 through which hot oil, hot water, steam or other heating medium is passed, or the coils may be heated directly by a gas flame.  The heater 2 may be omitted.  The caustic soda solution passes from pipe 23 through fine perforations 47 in the form of fine drops into the oil, and the mixture passes along the mixing space formed between a rod 44 screwed to the pipe 23 and the shell 41 of the mixer to the outlet pipe 46 which takes it to an agglomerator 5.  The mixture passes along a coil 52 in the agglomerator 5 in which the foots are agglomerated to larger masses and which is enclosed in a shell 51 through which a heating or a cooling medium may be passed or which may be filled with heat insulating material such as asbestos fibres.  The mixture of oil and foots next passes through pipe 53 to a centrifugal separator 6.  The oil and reagent are supplied by pumps 11, 12 at a pressure of 80 lbs. per sq. in. and are heated to about 160 DEG  F. before entering the mixer 4.

Title: Improvements in or relating to radio multi-channel broadcasting and relay systems
IPC: H04B7/17
Filed: 1945-04-13
Abstract: 600,273. Multiplex pulse signalling. STANDARD TELEPHONES & CABLES, Ltd. April 13, 1945, No. 9322. Convention. date, April 17, 1944. [Class 40 (v)] Relates to a multi-channel intercalated pulse train broadcasting system, the details of the main transmitter and receivers of which are described in Specification 600,272, and comprises also a relay station including means to suppress certain of the channels and to add others before re-radiation. This relay station comprises a directional receiving aerial 201, Fig. 8, feeding a detector 210, the output from which passes to the local radio transmitter 294 and broadcasting aerial 295, through a channel suppressor device 250 and a channel-adding coupling circuit 292. The various monitoring, channel-suppressing and channel-adding circuits are controlled by a base wave generator 214 synchronized by pulses from the synchronizing signal separator 212. For selecting the pulses of a single channel for the monitoring demodulator 230, the base wave is fed through an adjustable phase-shifter 220 to a deblocking pulse generator 222 whose output is fed, with the incoming signals, to a mixer 224 feeding the demodulator. The output from phaseshifter 220 is also applied to a frequencymultiplier 228, to provide a demodulating wave for circuit 230, which feeds the signal reproducer 234 through a filter 232. For suppressing undesired channel pulses, a blocking pulse generator 242 is fed through an adjustable phase-shifter 240 from the base wave generator 214, and its output supplied to the channel suppressor 250. Additional programmes from local studios X, Y, and from receiving aerial 283 and detector 282 are used to modulate pulse trains in circuits 271, 272, 285 respectively, fed with the base wave through individual adjustable phase-shifters 273, 274, 284 respectively and connected to the coupling circuit 292 through pulse shapers 280, 281, 286 respectively. The channel suppressor 250 comprises two valves 251, 252, Fig. 9, the signal pulses 211 from detector 210 being applied to the grid of valve 251 and the blocking pulses 243 from generator 242 being applied to the grid of valve 252. The anodes are connected together and the output taken from the common cathode resistance 257 to the clipper stage 262 which suppresses the blocked channels. Specification 538,036 also is referred to.

Title: Circuit for obtaining the ratio of two input quantities
IPC: G06G7/161
Filed: 1964-03-05
Abstract: 1,049,802. Electric analogue calculating. MONSANTO CO. March 5, 1964 [March 20, 1963; June 3, 1963], No. 9378/64. Heading G4G. An arrangement for obtaining the quotient of two quantities comprises a capacitor across which sawtooth pulses are produced, the amplitude of the pulses being dependent on a first signal, and the pulse duration being dependent on a second signal. As described with switch 44 in the position shown, capacitor 56 is charged towards a voltage determined by the speed of rotation of generator 28, and is periodically discharged through contacts 46 at a rate determined by the speed of rotation of generator 34. The amplitude of the sawtooth voltage thus developed across the capacitor 56 is dependent on the ratio of the rotational speed of shaft 20 to that of shaft 22. If switch 44 is moved to its other position the charging voltage for capacitor 56 is the difference between the voltages of generators 28 and 34 and the output is proportional to the difference in speeds divided by the speed of shaft 22. In a modification, Fig. 5, the discharge of the capacitor 124 may be controlled by either generator 136 or 138 depending on whether switch 166 or 168 is closed. Compensation for the effect of different closure time of contacts 160, 164 is made by means of adjustable resistors 174, 176 and the charging voltage is controlled by potentiometers 140, 152.

Abstract: 119,854. Hess-Ives Corporation, (Assignees of Ives, F. E.). Oct. 9, 1917, [Convention date]. Drawings to Specification. Colour photography; toning and after-treatment. -In the production of multi coloured photographs or kinematograph films two coloured images are produced by exposure &c. on opposite sides of a colloid layer supported on a base, or on colloid layers on opposite sides of a base; one image may be a copper-tuned silver image or a copper-toned and mordant-dyed silver image, and the, other image may be a cyanotype image. The first image may be printed on to a colloid layer sensitized with a silver haloid, and through the base supporting it, from a green-representing negative, and after development &c. of the image, the colloid layer may be re-sensitized in a 2 per cent bath of green citrate of iron and ammonia, blotted off, and dried. The other surface of the layer is then exposed under a red-representing negative, and the image is developed with a 1 per cent solution of potassium ferricyanide, the two images being confined largely to their respective sides of the colloid layer. The silver image is next converted into a red pigment image by means of a copper toning bath, and may be fixed with sodium thiosulphate, or the toning may be performed before the second sensitizing. The colour of the red image may be modified or intensified by treatment with a basic dye such as fuchsine or auramine which is mordanted by the copper image, and the colour of the cyanotype image may be modified by the addition of a reagent such as potassium permanganate to the developer, or by treatment after development with a dilute, slightly acid, solution of potassium bichromate. A third coloured image may be combined with images prepared as above set forth.

Filed: 1954-03-31
Abstract: 757,643. Welding by pressure; shearing; making electric relays. WESTERN ELECTRIC CO., Inc. March 31, 1954 [April 7, 1953], No. 9439/54. Classes 83 (2) and 83 (4)] In apparatus for welding contacts 10 on to the ends of wires 11 in a row on an electrical relay component 12, the component is supported with the wires each in alignment with a different one of a corresponding number of reciprocable welding heads 25 to which the contacts are automatically advanced so that they are held by the heads and then simultaneously percussively welded on to all the wires in the row. Vertically spaced tapes 53 equal in number to the wires 11 are guided through horizontal passages in a member 54, Fig. 1, to be fed by rollers 62, 63 into passages in a die 56. The roll 62 is intermittently driven through a ratchet from a cam 78 on the main drive shaft 45. The die passages intersect a vertical passage 80 in which a thin flat cutter 81 is reciprocated by a slide 82 and a crank arm 85 secured to a shaft 86 driven by gearing from the shaft 45. Contacts 10 are cut from the tapes by forward movement of the cutter and are carried by recesses 93 in the forward end of the cutter into a position in line with horizontal passages 94, formed in the die 56 and a member 96 and in the path of pusher rods 95 connected to a slide 98 and reciprocated in the passages 94 by a lever 100 actuated by a cam 103 on the shaft 86. The rods 95 are of different lengths and advance the contacts through different distances into alignment with vertical passages 109, spaced identically to the wires 11, and into the path of pusher fingers 110 slidable on rods 114 against springs 117. The fingers are moved downwardly to transfer the contacts to recesses 125 in a carrier 126 by a plate attached to a racked rod 127 reciprocated through gearing 130, 133, 134 and a bell crank 142 driven by a cam 145 on the shaft 45. The carrier is reciprocated by a link 150 and lever 151 from a cam 154 on the shaft 45 to bring the contacts in line with the welding heads 25. Each head is a flat bar 30 sliding in grooves in a block 32 under the action of a spring 35 and controlled by a cam 40, Fig. 6, on a shaft 42 chain driven from shaft 45. The cam 40 allows the heads to go forward so that resilient fingers 49 thereon grip the contacts. The heads are retracted the carrier is withdrawn and the heads are thrust forward by the springs 35 to engage the contacts and wires in a percussive weld. The heads and one side of each supply source 164, Fig. 7, are earthed and the wires 11 engage contacts 165 from the sources when the part 12 is raised by a piston 22 to clamp the part against a stationary holder 23.

Title: Magnetic domain register
IPC: H01F10/06
Filed: 1975-03-07
Abstract: 1493066 Magnetic domain registers TECSI (TECHNIQUES ET SYSTEMES INFORMATIQUES) 7 March 1975 [8 March 1974] 9500/75 Heading H3B A shift register comprises a soft magnetic domain propagation channel 2 having a longitudinal easy axis and supported by a non-magnetic substrate 1, an insulating layer 3, and a serpentine propagation conductor 4 whose width at least in those sections transverse to the channel is partially covered by soft magnetic material 5. The material 5 may be in discrete areas or formed by the same mask as used to define the conductor 4 as shown. Data is represented by domain pairs 6, 7 of which domain 6 is dispersable. Passage of a current pulse in the direction 8 generates a field pattern Ha which combines with that Hb produced by the material 5 to form Ht which, as it builds up, causes domain 6 to collapse, and domain 7 to elongate 9, 10 and as the field Ht reduces to divide into domains 11 occupying similar positions to those 6, 7 but displaced by half a pattern. A current pulse is passed in the opposite sense to drive the domains the next half pattern. The conductor 4 may be coated first with hard magnetic material (16, Fig. 2, not shown) before the soft material (17). The conductor pattern may link two propagation channels 2 for alternate operation, the channels containing related data. Sixteen registers, each having a long and a short conductor pattern (23, 24, Fig. 3, not shown) linking the same sixteen channels, may be serially connected by conductor pairs (26) commoned at one end (37) and extending parallel to channel pairs for writing-in or for differential read out. Hall effect read out may alternatively be employed. The register is made by chemically depositing in a 50 oe field a Co/Ni alloy on to a glass substrate where it has been previously catalysed by successive immersion in tin and paladium chlorides, photosensitive resin preventing deposition elsewhere. The 1000 Š layer is thickened to 6 Á by gold or copper which may act as the read or write conductor. The insulation is a 10 Á polyimide layer and the conductor formed by electrolysis in spaces left by a photosensitive resin mask which may be the same shape as that used for electrolytically or chemically depositing the soft overlay which however only forms on the conductor. Alternatively (Fig. 5, not shown) a soft layer is deposited on the substrate, the conductor pattern generated electrolytically through a subsequently dissolved resin mask, a hard layer chemically or electrolytically deposited on the conductor and the superfluous magnetic material removed by ionic engraving or selective etching to define the propagation channels, the whole then being covered by insulation.
