Title: Improvements relating to the manufacture of copper tubing
IPC: B23K13/04
Filed: 1959-04-17
Abstract: 882,256. Welding by pressure. MAGNETIC HEATING CORPORATION. April 17, 1959 [May 29, 1958], No. 13219/59. Class 83 (4). In making high-conductivity copper tubing a high-conductivity copper strip is continuously advanced and formed into tubular form with a V-shaped gap between the edges of the strip, the strip having a hardness sufficient for producing a gap having a constant V-shape terminating at a weld point where the edges are pressed together, the edges are heated to welding temperature at the weld point by applying high-frequency electric current to the strip through electrodes which engage the strip on or near the edges shortly in advance of the weld point, the current being at such a frequency that the lowest impedance path for the current between the electrodes follows the gap edges to the weld point and the angle of the gap and the speed of advance of the strip are so related to one another and to the current that a forged weld is formed and the line of the weld includes substantially no discernible cast metal when cross-sections of the weld region of the tubing are etched, whilst the ductility of the weld zone and tensile strength of the tubing across the weld, after annealing the tubing, are substantially as high as those of the unwelded zones of the tubing. An open-seam tube 10 formed from copper of at least 97% purity and at least “ hard is advanced in the direction of the arrows through the welding zone where fluid cooled contacts 14, 15 connected to a source of current of 100,000 or higher, e.g. 400,000 cycles per second, engage the strip edges so that current flows around the weld point. The contacts may comprise a shoe of high temperature and high wear-resistant metal brazed &c. to a fluid cooled holder. The current in the circumferential direction of the tube is impeded by a rod 17 of ferromagnetic non-conducting material mounted within the tubing in a chamber 18 through which cooling fluid is introduced as described in Specification 811,251. The material within the tubing may be as described in Specification 772,279. The edges of the strip are guided by means 21 e.g. as described in Specification 772,279 or U.S.A. Specification 2,818,489. The heated edges are forced together .by non-magnetic aluminium bronze rollers 12, 13 with semi-circular peripheral grooves and an air jet 30 blows the arc at the weld point towards the apex of the V-gap. The high-conductivity copper contains 97% or more copper and has electrical conductivity of approximately 100%. Specification 748,528 also is referred to.

Patent GB-132512-A (GB)
IPC: G01F13/00
Abstract: 132,512. Reinhard, R. Sept. 8, 1919. Disinfecting.-A valve device for the sterilized withdrawal of predetermined quantities of liquids such as serum or vaccine comprises electricallyoperated valves controlled by switches operated by an electric motor. On closing the main switch J, the motor M is started and a solenoid R<1> in parallel with the motor energized to close a switch K in parallel with the switch J, so that the switch J may then be opened. The motor, acting through worm gearing S, drives a shaft Q carrying contact disks E, C, G, F. The pin G<1> on the disk G first contacts with G<2> to energize a magnet 0, which attracts an armature Y to open the gas valve Y<1>. Gas is thus supplied to a Bunsen burner T, where it is ignited by a pilot-jet, and the flame plays on the delivery nozzle V and the neck of the receiving flask V to sterilize them. The pin G' next contacts with G<3> to energize a magnet P, which attracts the armature Y to close the gas valve. A contact of adjustable length on the disk C then contacts with N to supply energy to a magnet B to withdraw an armature normally pressed against a pipe W, to permit the liquid to flow. After the flow has ceased, a gap L on the disk F breaks the motor circuit, which opens the switch K and, unless the switch J has been left closed, brings the apparatus to a standstill.

IPC: B27M3/20
Abstract: 132,569. Marks, E. C. R., (Blake, Inc., C. C.). Aug. 7, 1918. Carving.-Comprises a machine for cutting a shoulder 3, Fig. 10, on the bottoms of lasts for use in making welt shoes. The vertical face of the shoulder is cut by a conical face 60 of the cutter 59, which is carried by an inclined shaft 63 rotated by a motor 72, all mounted on a counterweighted vertical slide 65 carried by a bracket 66 horizon. tally slidable on a column 10 to and from the last 1. The last is fixed on a support 6 secured at the bottom to a templet 11 adapted to slide over a table 8. The templet is fed to move the last past the cutter by a pinion 13 in gear with teeth around its periphery. The pinion 13 is rotated by a motor 20 acting through worm gearing 17 and a clutch 22, which is adapted to be thrown in against the action of a spring by means of a treadle 27. A guiding-flange on the templet is gripped between rollers 30, 31 on the outside and a finger 29 on the inside, arranged to cause the last always to swing around the point of operation of the cutter, and the rollers are carried by a slide 43 controlled by a spring-pressed toggle 45, 46, so that the rollers hold the templet more firmly when rounding the toe than when traversing the shank. To release the templet from the table 8, a shaft 39 is rocked by a hand-lever 41 to move a slide 37 horizontally, and cam-slots formed in the slide simultaneously depress the finger 29 to beneath the level of the table 8 and move the slide 43 to disengage the rollers 30, 31 from the templet. To cause the cutter 59 to rise and fall with the surface being cut, an arm 74 secured to the slide 65 carries a roller which engages the last close to the cutter, and, by turning an eccentric pin 77 to rock the arm 74 downwards, the cutter can be raised out of contact with the work. When a toe-box is to be inserted in shoes, necessitating a shoulder 3 which recedes from the toe of the last, a special cam-surface is formed on the templet, and a feeler 83 contact with this controls the inward movement of the cutter-carrying slide 66 under the action of a spring 84.

Title: Translating apparatus
IPC: H03M7/40
Filed: 1976-04-01
Abstract: 1534069 Variable-fixed length decoders INTERNATIONAL BUSINESS MACHINES CORP 1 April 1976 [19 May 1975] 13275/76 Heading G4A A minimum redundancy Huffman variable length codeword C v (i) is decoded to a fixed length character f(i) by performing successive computations on functions s(i) of the populations of the different lengths of codewords in the code as successive codeword bits are received. The preferred code has the following properties:- (1) codewords of the same length are successive binary integers. (2) For codewords of more than k bits, their k-bit prefix t(k) is greater in value than any k-bit codeword. If s(i) is the number of variable length codewords of length i bits in the code, then, for k>1, the number of codewords of k bits or fewer is b(k) = s(k) + b(k-1); for words of more than k bits, the smallest prefix t(k) = the highest k-bit codeword + 1 = 2 À t(k-1) + s(k); and for k = 1, b(1) = t(1) = s(1). The index i of a table of fixed length characters f(i), arranged in descending order of probability, can be obtained from the relationship i = y(k) - t(k) + b(k), where y(k) is a k-bit codeword. The values of t(k) and b(k) may be stored in look-up tables or, as in the preferred embodiment, may be obtained from accumulations of values from a table of s(i). Such a decoder allows the code to be changed at will to suit the different fixed length character frequencies of different data bases simply by altering the stored tables. In the system described a variable-length codeword source supplies successive bits in response to successive clock À pulses from a receiver for the fixed length characters, transmission of further bits being inhibited temporarily when the decoder determines that a complete codeword has been supplied. Values s(1), s(2)- s(k) are read from the table of values s(i) as successive bits y 1 , y 2 -y k  are received by the decoder. A pair of accumulators (feedback adders) derive t(k) and b(k) from s(1) to s(k). A further adder performs the comparison of y 1 , y 2 -y k  with t(k) by 2's complement addition, a change to a negative result indicating that the codeword is complete. The subtraction result is then added to b(k) to obtain the index i for look-up in the table of fixed length characters f(i).

Abstract: 931,140. Automatic control of aircraft. KOLLSMAN INSTRUMENT CORPORATION. April 19, 1960 [April 20, 1959], No. 13709/60. Class 38 (4). In a system for automatically maintaining constant altitude, airspeed or mach number of an aircraft a pressure-responsive device adjusts an E-I type electrical pick-off through an electromagnetic clutch which slips when the pick-off reaches limiting positions. In Fig. 5 links 50, 52 are attached to pressure-responsive capsules (not shown) on an aircraft so that a shaft 46 is rotated in response to altitude changes. When it is desired to maintain a constant altitude an electromagnet 102 is energized so that a sleeve 80 of magnetic material freely rotatable on shaft 46 is drawn into engagement with a friction disc 74 adjustably secured to shaft 46. An armature 70, which is normally maintained in a central position relative to an E-type pick-off 62 by springs 83, 84, is coupled to sleeve 80 so that signals dependent in magnitude and sense on altitude changes are produced by the pick-off when electromagnet 102 is energized. These signals are utilized to maintain constant altitude by controlling the pitch channel of the aircraft's automatic pilot (not shown). The magnitude of these signals is limited by adjustable stops 85, 86 and slip between discs 74, 80 when the limits are reached permits the automatic control to be overridden manually to set a new altitude without deenergizing electromagnet 102. The energization of electromagnet 102 and pick-off 62 from an A.C. source is adjustable by rheostats (not shown). Specification 916,434 and U.S.A. Specification 2,689,951 are referred to.
