Title: Apparatus for holding electronic components during the assembly of circuit arrangements
IPC: H05K1/00
Filed: 1973-09-18
Abstract: 1441016 Component assemblies C R WAINWRIGHT 18 Sept 1973 [26 July 1973] 43783/73 Heading H1R Electronic components are supported on an insulating plate member formed on one side with a thin metal, e.g. printed solderable circuit pattern 6 comprising, e.g. metallic areas 7 extending radially from the centre, and outlying areas 8 to which integrated circuit connectors may be soldered, with other components solderably connected to the outer margins. The supporting members have self-adhesive layers on their rearward sides protected by a removable covering (Fig. 2, not shown) and are pressure secured to a base 10 of insulant, e.g. plastic material with a thin metal, e.g. earth sheet thereon. Before adhesion the connections of components 2, 3, 4 are soldered to the metallic areas together with insulated outgoing and interunit connections 14 and earth connections 15. Certain components, e.g. resistor 4 are connectively soldered to the metal coating of the bass-plate and the components may comprise transistors, potentiometers, inductors, fixed and variable capacitors, transformers, pins and sockets, plug connectors, diodes and the like. The connection patterns may provide specific impedances or transmission lines. The supports may be rectangular or strip-like, and the baseplate may have a shielding function, while the invention is applicable to the construction of experimental circuits ad hoc.

Title: Data error detector for determining the error rate prior to equalization
IPC: H04L25/03
Filed: 1971-09-22
Abstract: 1326185 Digital transmission; error correction GTE AUTOMATIC ELECTRIC LABORATORIES Inc 22 Sept 1971 [23 Sept 1970] 44277/71 Heading H4P In an error detection system received signals are passed to a transversal filter to produce an equalized signal which is compared with the original signal to provide an indication of errors when the signals do not correspond. The sensor may be of analogue, e.g. a tapped delay line or of digital form and data signals may be of binary, multilevel or correlative type. Input signals to a sampler 28 providing a PAM output which is quantized in coder 34 to provide a parallel n digit output, each parallel group representing one PAM sample and passed to arithmetic unit 42 where it is converted to signed, i.e. Œ, magnitude form to facilitate arithmetic operations. The output is passed to a decoder 44. The most significant magnitude digit (X1) provides a delayed binary equivalent of the unequalized input signal and is passed on lead 38 to flip flop 40 of comparator 14<SP>11</SP>. Where equal and unequal outputs are the same, e.g. both 1's inputs to NAND gate 54 are in 0's and input to NAND gate 56 are 1's hence NAND gate 62 has 1, 0 inputs and a 1 output to NAND gate 68 hence when a 1 timing signal appears on lead 66 a '0' is applied to error indicator 19<SP>11</SP> and no indication occurs. When equalized and unequalized inputs to comparator 14<SP>11</SP> are not the same the 1, 0 input to gate 68 causes a 1 input to indicator 1911 an error indication will occur. In Fig. 2 (not shown) a tapped delay line (21) together with a summation circuit (27) are used as the main components of the filter the unequalized output being taken from the main tap (23C). This avoids the use of a separate time delay network where the detector (11<SP>1</SP>) had been tapped from the input as illustrated in Fig. 1 (not shown). In the latter arrangement the filter includes means to compensate for phase and amplitude distortion before decoding.

Title: Method of raising sunken or stranded vessels
IPC: B63C7/12
Filed: 1965-11-02
Abstract: 1,062,145. Raising sunken vessels. K. K. K. KROYER. Nov. 2, 1965 [Nov. 4, 1964], No. 46344/65. Heading B7S. Sunken vessels are raised by feeding into their interiors buoyant bodies (9), Fig. 1 (not shown), from a water container (5) in which water is maintained at a constant level by supply pipe (10) and overflow (7), conveying by perforated buckets (16) buoyant bodies (9) down below this constant surface level and releasing the buoyant bodies so that they will pass close to the inlet end (6) of the suction pipe (4) of a pump (1). The buoyant bodies (9) are caught by the stream of water generated by pump (1) and are carried through suction pipe (4) and tube (3) into the interior of the vessel. Perforated buckets (16) are attached to bucket wheel (11) which has propeller-like spokes (15) having an adjustable pitch. The rate of feeding the buoyant bodies into the sunken vessel can be regulated by the speed of rotation of the bucket wheel, the pitch of the propeller-like spokes (15) or by the position of the buckets (16). In another embodiment of the apparatus the conveying means consists of a vertical or inclined screw surrounded by a housing, the upper part of which is formed as a hopper for the buoyant bodies which may be gas-containing polystyrene balls or pieces of cellular plastic material. An adhesive of asphalt may be applied to the buoyant bodies after their introduction into the interior of the sunken vessel.

Abstract: 1,204,876. Measuring angular speed electrically. KONSTRUKTORSKOE BJURO TERMOPRIBOR. Sept.29, 1967, No.44373/67. Heading G1N. A three phase tachometer Fig.l having a rotor 1, and stator windings ABC, has a saturable transformer 3 connected to one phase A, and a phase-sensitive rectifier 6 connected to the saturable transformer output winding 5 and controlled by the voltage across the other two phases BC, to provide a D.C. output in a load which varies in magnitude and polarity with the speed and direction of the rotation of the rotor. The voltage pulses (u), Figs.2, 3 (not shown) produced by the transformer winding 5 are gated by the rectifier 6 when the phase voltage U BC  is positive, so that positive pulses appear in load 10 for one direction of rotation (AG2) and negative pulses for the other direction of rotation Fig.3 (not shown). Various refinements and more complex circuits are described using controlled rectifiers, or transistors as the phase sensitive rectifier. A six phase tachogenerator Fig.4 (not shown) has four controlled rectifiers (13, 14, 15, 16) controlled by four respective phases (Al, A2, C1, C2,) and the two remaining phases (B1, B2) drive respective saturable transformers (21, 22) controlled by the rectifiers. Inter-connected control windings (32, 33) cause one transformer to be blocked when the other receives a voltage pulse on its primary. The secondaries drive differentially connected rectifier circuits (27, 28) driving a load (31). The controlled rectifiers may be in the control winding circuit in another three phase embodiment Fig.7 (not shown), the control winding thus blocking one of two saturable transformers (35, 36) in response to an input pulse gated by a controlled rectifier, and allowing the other transformer to drive the output circuit. In a further embodiment Fig. 8 (not shown) a transistor controlled phase shifter (64) is included, controlled by a differential rectifying circuit (90) connected between two phases (BC), and being associated with saturable transformer (66) and phase sensitive rectifier (85). In this embodiment and in that of Fig. 9 (not shown), the loading of the phases is non-symmetrical and use is made of the fact that as a result of the unequal loading the phase B voltage is greater than the phase A voltage for one direction of rotation and less for the other.

Abstract: 1392129 Impermeable laminates BITUMARIN NV and ASPHALT-EN CHEMISCHE FABRIEKEN SMID & HOLLANDER NV 4 Oct 1972 [7 Oct 1971] 45700/72 Heading B5N [Also in Divisions B2 and E1] Broad sheets of coating material are obtained by passing a carrier through a molten coating composition to coat both surfaces of the carrier with the composition, and placing the coated carrier before it has cooled appreciably on to an endless conveyer belt on which cooling takes place. The conveyer belt may be of silicone rubber or it may be a laminate consisting of or coated with polytetrafluoroethylene. A surfacing material may be disposed between the coated carrier and the conveyer belt so that the surfacing material prevents the coating composition from adhering to the conveyer belt. The surfacing material may be fine grained sand which may be sprayed against the underside of the carrier coated with coating composition or it may be inserted in strip form for example by hand rolling from a reel, between the carrier coated with coating composition and the conveyer belt. Several strips of surfacing material may be used which together cover the total width of the underside of the coated carrier. Suitable surfacing materials are paper sheet and/or plastics film. It is preferred to use two or more strips of surfacing material and the material of at least one of the strips is so chosen that it can be easily removed afterwards so as to expose a margin of coating composition to which a following sheet can be cemented or bonded. For this purpose a plastics film such as polyethylene may be employed, the other strip or strips which need not be removed afterwards could be of paper. The upper surface may be coated with a further surfacing material which may be in granular form or in the form of a strip, such as a layer of felt, a fabric or a film. The sheet material may include a polyester film, internally or externally, and adjacent to the carrier. An external film may constitute the solid further surfacing. The carrier may be a fabric produced from polyamide filaments. The coating compositions may be of montan wax, rosin, petroleum bitumen and coal tar. A filler such as asbestos fibre may be present.
