Title: Electric pulse-time modulator
IPC: H03K7/00
Filed: 1948-02-19
Abstract: 653,824. Pulse modulation; pulse generating circuits. BENDIX AVIATION CORPORATION. Feb. 19, 1948, No. 4956. Convention date, Feb. 21, 1947. [Classes 40 (v) and 40 (vi)] The recurrence frequency of the pulses from a blocking oscillator is controlled by a modulating voltage, and the generated pulses are applied to complete a normally interrupted path to apply a reference voltage to the oscillator input circuit. In one embodiment, a blocking oscillator 10 has its grid circuit completed through the cathode resistance 19 of a cathode follower valve 27 fed from the signal amplifier 28, so that the pulse timing depends on the amplitude of the signal. In order to ensure that the grid 14 of valve 10 swings to the same potential at each cycle, the pulse output, from anode transformer 13, 20 is applied to the grid of a valve 23 which is thereby rendered con. ducting for the duration of each pulse and the cathode of which is connected to the control grid of valve 27. This clamps the potential of the upper end of resistance 19. In a simplified circuit, Fig. 2 (not shown), the valve 27 is omitted and the valve 23 is a gas-filled triode.

IPC: F16L13/11
Filed: 1922-02-21
Abstract: 197,080. Conradi, H. Feb. 21, 1922. Butt joints.- The plain or flangeless ends of concrete or like pipes A, B, are joined by forcing a jointing ring C of rubber or like resilient material by means of a plain clamping-band or a band such as D, Figs. 1 and 3, tightened around its circumference, into the circular groove 3 formed by the bevelled meeting ends of the pipes. The pipes are packed around with earth, spaces being left to complete the joint, or other means are provided to prevent longitudinal separation of the pipes while being joined. The inclined or bevelled ends 1<a>, 2a of the pipes may be angular, corrugated, or curved, and the packing-ring C approximates in section to the shape of the groove and may be built up of connected sections. The ring C is of greater depth than the groove 3, and, when the clamping-band is tightened, it is pressed outwards to overhang and bear against the ends of the pipes. The clamping-band may be provided with inwardly projecting flanges at its edges to protect the packing-ring C, and the space F may be filled with cement for the same purpose. The resiliency of the packing-ring C permits it to adjust itself to irregularities on the pipe ends as well as permitting a slight deviation of the pipe line from the straight. The metal parts may be galvanized. The clamping-band D may be provided with a continuous or interrupted web D, as shown in Fig. 1, which is compressed, when the band is tightened, into a recess formed in the periphery of the packing-ring C. The band is provided with lugs D<6>, which are drawn together by a bolt D<4> and nut D<5>, and the space between them is bridged by a part D<8> integral with or separate from the band D. The bolt D<4> may be riveted or otherwise secured to the band. An alternative form of band is shown in Fig. 5, in which the lugs D' and bridge D<10> are integral with the band, and a removable split-ring held in recessed lugs D<12> in the band, takes the place of the web D<1>.

Title: Method of producing large-surface mouldings from fibrous filling material and synthetic resin as binder
Inventor: BARTHEL WOLFGANG
Filed: 1959-02-16
Abstract: 858,493. Treating fibres and forming laps. SACHSENRING AUTOMOBILWERKE ZWICKAU VEB. Feb. 16, 1959, No. 5381/59. Classes 120(1) and 120(3). [Also in Groups V and VIII] Large surface mouldings are produced by sprinkling a fibre fleece, delivered from a carding machine with powdered synthetic resin, laying the fleece in zig-zag folds on a moving belt, pressing and heating the folded layers, cutting them, and moulding the cut pressed fleeces under heat and pressure. The nature of the fibres, and of the resins, may vary or may be the same throughout. The flecees 2 emerge from a carding machine 1, are sprinkled by a device 3 with powdered resin, and are fed by rollers 4 on to the belt 5, on which they are lightly pressed together by rollers 7. As the fleeces are fed the fibres may be aligned transversely by moving bands. The belt carries the laminations through rollers 14, which press them together, and then through lengthwise cutters 10 and crosswise cutters 11. The laminations may be passed through a heater 9, e.g. infra-red ray. Different quality fleeces may be fed side by side from the first and last carding machines, resulting in a product with higher quality fibres outside. By such a feeding arrangement one carding machine only may be used. Fabric or plastic webs, drawn off rollers, may be incorporated. Fig. 6 shows a mechanism by which fleeces are laid across the belt 5. They are carried by an auxiliary belt 15 over a laying frame which comprises two limbs 23, 24 at an angle to one another, with a roller 25 at the far end which is reciprocated by a chain 28. On the block 26, on which the roller 28 is mounted, is also mounted a frame 31 with two pressing rollers 32, 33. By the reciprocation of the roller 25 and the movement of the belt 5 the fleeces are laid in staggered formations, which are pressed down on the belt 5 by the rollers 32, 33 which may be perforated to allow free escape of air. A strip of rubber 41 cleans the belt 15. The limbs 23, 24 are kept in equilibrium by a weight 37 acting through a rope 26. Specification 806,886 is referred to.

Abstract: 1414204 Fluid-pressure servomotor systems MATERIEL ELECTRIQUE DE CONTROLE ET INDUSTRIEL 5 Feb 1973 [14 Feb 1972] 5520/73 Heading G3P A two-stage pneumatic amplifier has an input 4, Fig.4, supplied with pressure P 1  and a restricted input 6 supplied with pressure P2 to move a membrane 2 relatively to outlet aperture 8 and thereby establish a flow Q therethrough of a magnitude proportional to P 2 -P 1 . The flow Q passes to atmosphere via resistance 14 and thereby establishes a pressure P in a compartment 12. The pressure P acting on membrane 10 causes it to variably restrict an orifice 16 which vents to atmosphere a quantity of fluid supplied at pressure Pa, and thereby controls the value of the amplified outlet pressure tapped intermediate the orifice 16 and a resistance 18. Floating membrane 17 prevents vibration of the membrane 10. A further stage, Fig.3 (not shown), similar in structure to the first stage, may be located upstream and supplied with pressures P 2  and Pa to develop an output pressure P 2  which is supplied to the input 6. The amplifier may be used to maintain a liquid level in a tank 33, Fig.6, by supplying input 4 with a pressure representative of actual liquid level, supplying input 6 with a pressure set by a variable resistance 34 and representative of desired liquid level, and using the output pressure Ps to control a power amplifier 35 which actuates a servomotor operated valve 37.
