Abstract: 1,074,156. Transistor frequency changer circuits. SIEMENS A.G. Sept. 23, 1964 [Sept. 24, 1963], No. 38713/64. Heading H3T. A transistor self-oscillating frequency changer circuit is provided with two series connected R.C. networks R 1 C 1 , R 2 C 2  connected to the emitter; network R 2 C 2  having a smaller time constant than network R 1 C 1  so as to avoid hunting. The H.F. signal is fed from the secondary of R.F. transformer L and is mixed with the oscillator signal to produce an intermediate frequency ZF. The frequency of the oscillator is determined by the line circuit Z and is controlled by C 3 . The emitter voltage is fed in at 1 and the resistors R 1'  R 2  stabilize the circuit against temperature variations. The decoupling capacitor C 2  provides the circuit with a low input impedance at the intermediate frequency.

Abstract: 1277297 Measuring depths of bore hole SCHLUMBERGER INLAND SERVICES Inc 5 Aug 1969 39043/69 Heading G1N The depth of a tool in a borehole is determined by measuring the length of cable played out and modifying this dimension in accordance with the cable stretch as calculated by measurements of the tensions at the top and bottom of the cable and utilization of the physical constants of the cable. The cable 12 Fig. 1 is fed out over a pulley 17 and the nominal length L m  is determined at 19. The tension at the bottom end is measured by strain gauge elements R2, R4 connected in a bridge circuit 39, all treated in downhole housing unit 10a, and the bridge output is fed via power cable 43 and amplifier 45 to computer 48, which is also fed with the physical constants of the cable material and the connected running length L by a shaft 59, to give an output signal representing the cable length error due to downhole tension. Similarly the uphole tension is measured by strain gauges 22, connected in a bridge circuit 23, to produce an output signal representing cable length error due to uphole tension. Both output signals are combined in computer 20 with the nominal length signal L m  from unit 19, additional inputs being correction factors L t , representing temperature and L D P,  representing difference in depth when using a drill pipe, these factors having predetermined value/depth relationships which are set up on potentiometers 28, 34, whole slides are also coupled to shaft 59. The output from computer 20 is recorded at 14, together with other signals representing parameters measured at the bottom end of the cable, whereby these parameters are correctly plotted on a chart 50 against true depth.

Title: Process and apparatus for forming a laminated hollow article
IPC: B29C51/32
Filed: 1976-09-22
Abstract: In the process, a web-shaped thermoplastic substrate (34) is taken off from a supply roll (16), preheated (18), received by a conveyor belt (44) and fed, while being kept warm, to consecutive workstations (A-E). In the first (A) thereof, the substrate is provided within a region with a flowable thermoplastic material (68) which, in a second workstation (B), is combined with the substrate to form a thermoplastic laminate. The latter passes to a preforming station (C) to form a preform. The preform passes to a turntable (152) and is cut out of the web before its introduction into a blow-moulding station (D). In the blow-moulding station (D), the hot preform is formed into the hollow body (200), the substrate (34) forming the hollow body inner surface and the applied plastic material (68) forming the outer surface of the hollow body. In subsequent cooling and stabilising stations on the turntable (152), the hollow body (200) is cooled and finished. The process makes possible the cost-effective production of oxygen-tight containers and the recycling of the individual material residues. <IMAGE>

Abstract: 1,083,138. Rolling. UNITED ENGINEERING & FOUNDRY CO. Sept. 24, 1964 [Oct. 7, 1963], No. 39371/63. Heading B3M. [Also in Divisions B5 and D2] A fluid control system for a rolling mill, or a paper or rubber calendering mill, includes cylinder assemblies 16 and 17 which urge the work rolls 12 towards each other, the pressure in the two assemblies being simultaneously or differentially variable by a controller 27 operating two relief valves 23 and 24. Motor-driven two-way pump 21 supply the assemblies 16 and 17, the pressures in the assemblies being determined by the axial position of control rods 36, Fig. 2, of the valves and indicated by gauges 93 and 94. The controller 27 includes two parallel shafts 57 and 63 which are connected to the rods 36, each shaft including an internally threaded worm-wheel 83 or 84, co-operating with a vertical worm 85, and an axially slidable keyed gear-wheel 61 or 65, co-operating with a pinion 67. The pinion 67 normally locked in position by a detent which, when released, allows simultaneous rotation of the gear-wheels 61 and 63 by a hand wheel 56, thus causing the shafts to be moved axially due to the rotation of their threaded portions 81 and 82 in the worm-wheels 83 and 84. For differential movement of the shafts the worm 85 is rotated by a further hand wheel to cause opposite rotation of the two worm wheels.

Title: Logical operation circuit
IPC: H03K19/10
Filed: 1960-11-16
Abstract: 946,783. Tunnel-diode switching circuits. KOKUSAI DENSHIN DENWA KABUSHIKI KAISHA. Nov. 16, 1960 [Nov. 16, 1959; March 23, 1960], No. 39416/60. Heading H3T. A circuit for performing logical operations comprises two tunnel diodes connected in adjacent arms of a bridge so that by applying an input signal across one diagonal of the bridge and an energizing signal across the other terminals one tunnel diode may be made to assume a low-current high-voltage state and the other may be made to assume a high-current lowvoltage state, depending respectively upon the polarity of the input signal, and thereby develop an output signal whose polarity depends upon that of the input signal. In Fig. 3A when exciting power in the form of square-wave pulses is applied to terminals 1, 2, tunnel diodes D E1  D E2  will assume states in which one is more conductive than the other, depending upon whether point A is initially positive or negative with respect to point B as determined by the polarity of the input signal applied to terminals 3, 4. Thus, if A is initially positive with respect to B, diode D E2  will assume the more conductive state when excited by the application of an energizing pulse and point B will assume a negative potential with respect to point A, whereby an amplified version of the input signal will be obtained at the output terminals 5, 6. The circuit may be modified to permit the use of a sinusoidal instead of a rectangular energizing voltage waveform Fig. 3B (not shown). By connecting the circuits of Fig. 3A in cascade as shown in Fig. 4 and applying energizing pulses whose phases are successively displaced by 120 degrees, Fig. 5A (not shown), a circuit which functions as a shaft register may be obtained. As shown in Fig. 6, a plurality of inputs may be connected in parallel at the input terminals of the circuit of Fig. 3A, the circuit then functioning according to a system of majority decision logic. The circuit may be made to operate as an OR-gate or an AND-gate by maintaining one input at a value corresponding to 1 or 0 respectively. In Fig. 8 a square-wave read-out voltage is applied to transformer T2 in quadrature with the energizing waveform applied to transformer T1. The application of the energizing waveform causes the tunnel diodes D E1 , D E2  to assume states dependent upon the polarity of the input signal; the reed-out pulse then causes a voltage to be developed at the output whose polarity depends upon which of the tunnel diodes is the more conductive. The circuit may be modified for actuation by sinusoidal waveforms in quadrature.
