Title: Improvements in or relating to semi-conductor arrangements
IPC: H05K3/32
Filed: 1961-11-16
Abstract: 957,910. Semi-conductive devices. SIEMENS & HALSKE A.G. Nov. 16, 1961 [Nov. 16, 1960], No. 41022/61. Heading H1K. [Also in Divisions B3 and H2] Connection is made to a terminal of a semiconductor device by compressing a spherical metal pellet between the terminal and a contact member so that the pellet deforms and provides cold welds joining the contact member to the terminal. As shown in Fig. 4, emitter and base electrodes 15 and 16 on the silicon body 10 of a transistor are joined to contact members 12 and 13 by compressing spherical pellets of gold 24 and 25 between them. The contact members have depressions into which the gold pellets are compressed. If the electrodes 15 and 16 are too small for the pellets to be located on them with ease the pellets are initially attached to the electrodes by means of a preliminary deformation, soldering or alloying process. As shown in Fig. 1, connections may be made between electrodes 19 and 20 on a semi-conductor body 1 said to comprise both active and passive elements. To this end an overlying ceramic plate 2 has a metal coating 8 extending between the electrodes 19 and 20 so as to make contact with spherical gold pellets 4 and 9 located in etched depressions in the electrodes 19 and 20. By compressing the ceramic plate on to the semi-conductor device the gold pellets are plastically deformed to provide cold welds. Instead of locating the pellets in etched depressions a mica plate may be used to hold the pellets in the required positions. Alternatively, the pellets may be flattened so that when they are placed on the semi-conductor device they do not roll out of position. Instead of a ceramic plate 2, a further semi-conductor device may be interconnected by this method with the semiconductor device 1. To form the pellets liquid gold is dropped or sprayed from a nozzle into a vessel and to reduce the size of the pellets a potential may be applied between the nozzle and the vessel to reduce the surface tension of the liquid gold.

Title: A control arrangement for a rotary regulating unit
IPC: H03M1/00
Filed: 1962-11-02
Abstract: 1,029,137. Electric selective signalling. LICENTIA PATENT - VERWALTUNGS - G.m.b.H. Nov. 2, 1962 [Nov. 2, 1961], No. 41553/62. Heading G4H. The output member of a feedback positioning system can be positioned over a range of almost 360 degrees by arranging that when the desired and actual positions are in different halves of this range, the output member is driven towards the mid-point of the total range by a first error signal representing the difference between this mid-point and the actual position, until the desired and actual positions are in the same half when a " true " error signal is used. The error signal to be used at any given time is selected by a two-position switch controlled by suitable logic circuitry. In Fig. 6 (not shown), a keyboard selects a tapping of the secondary of a transformer to produce the " true " error signal, the transformer primary receiving a 3- phase signal representing the actual position which is also fed to a further transformer to produce the first (" mid-point ") error signal. Alternatively (Fig. 7, not shown) a single transformer may be used, the switch being in its input. In another modification (Fig. 8, not shown) control of the switch is performed by comparing the desired position and the previous desired position (rather than the actual position), except for the first positioning subsequent to switching on.

Title: A three-phase electric power meter or energy meter
IPC: G01R11/36
Filed: 1966-09-22
Abstract: 1,098,159. Counting apparatus. SIEMENSSCHUCKERTWERKE A.G. Sept. 22, 1966 [Sept. 29, 1965], No. 42424/66. Heading G4D. [Also in Division G1] The three electromagnetic drive systems of a three-phase electric power or energy meter of the induction type each act on a separate one of three rotor discs 10, 20, 30 whose respective shafts 11, 21, 31 are not mechanically coupled. The separate systems for each phase may be contained in a common housing but sufficiently spaced apart to ensure that there is no electromagnetic coupling between the systems. Figs. 1 to 6 (not shown) depict arrangements which allow this criterion to be met in a tolerably compact manner. For energy registration, each system may have its own counting mechanism, with or without an associated totalizing register. Fig. 9 shows a suitable registration system, in which each phase has its own counter device 6. Each such device consists of a Hall effect generator sensing the successive transists of a magnetic member carried by the rotor and produces pulsed operation of a corresponding one of three register-operating relays 9. The three registers 130, 230, 330 may be mechanically inter-connected to drive a total register 102, and there may also be an associated maximum demand register 103. In Fig. 10 (not shown), the mechanical registers of Fig. 9 are replaced by step-by-step electric motors. An alternative totalizing register system (Figs. 7 and 8, not shown) involves the use of mechanical counters for each phase, and a set of magnets associated with each counter mechanism. These magnets when scanned by a device embodying a Hall generator produce a set of pulses indicative of the counter condition. Summation of the indications of the three counters may be effected by a computer in response to the three sets of pulses produced when the Hall generator device scans the three sets of magnets in sequence.

Title: Improvements relating to ethylene terephthalate polyesters
IPC: C08G63/82
Filed: 1959-12-14
Abstract: Ethylene terephthalate polyester compositions having a high melt viscosity but which are spinnable to filaments having a low relative viscosity have dissolved in them a boron compound in such amount that the polyester contains at least 0,5 mol. per cent of boron. Preferably the compositions are made by (a) adding to the polyester precursor 3-20 mol. per cent of a soluble boric acid, organic borate or inorganic borate of formula Xm-1Bq\Op where X is hydrogen or metal having the valence of n, m is 1-7, n is 1-3, p is 1-8 and q is 2-15 and wherein <F\1> and (b) subjecting the composition to polyesterification conditions in the presence of a catalyst (e.g. antimony trioxide, tetraisopropyl titanate or manganous acetate). The polyesterification mixture may also include titanium dioxide and phosphoric acid.  The boron compound may also be added to the preformed polyester.  Specified boron compounds are boric acid, boric oxide, sodium tetraborate, methyl metaborate, methyl polyborate, triethyl borate, triphenyl borate, glycol borate and glycol metaborate.  The polyester is one in which at least 75% of the residues are ethylene terephthalate radicals but it may also contain the residues of another dicarboxylic acid (e.g. adipic, sebacic, isophthalic, 5-(sodium sulpho)-isophthalic, bibenzoic, hexahydroterephthalic, diphenoxyethane-4,41-dicarboxylic or p,p1-sulphonyl bibenzoic acid) or another glycol (e.g. tetramethylene-, hexamethylene-, decamethylene-, 2,2-dimethyl-1:3-propylene-, trans-p-hexahydroxylylene- or diethylene-glycols, or bis-p(b -hydroxyethoxy) benzene, bis-1,4-(b -hydroxyethoxy)-2,5-dichlorobenzene, or bis-[p-(b -hydroxyethoxy) phenyl] difluoromethane.  The polyesters may be made into staple fibres having a less tendency to "pill".  Thus polyethylene terephthalate containing 2,0% by weight of boric acid may be melt-spun into yarn which is drawn 3,26% in a water bath at 100 DEG C., and then heated in an oven maintained at 100 DEG C. whilst free to relax and finally cut up into 1,5 inch lengths.  Specifications 578,079 and 841,230 are referred to.
