Filed: 1969-11-10
Abstract: 1,236,866. Endless conveyers. WAAGNERBIRO A.G. 10 Nov., 1969, No. 54998/69. Heading B8A. The load carrying run of an endless conveyer belt 1 is located within a trough 2 provided with longitudinal rails 3 and air pressure chambers 4 for supporting the belt. A compressor, via pipes 14, 15, air reservoirs 9 and a distributing channel 6, provides air under pressure which causes the belt to substantially float on the rails 3. The conveyer may comprise a number of units with a guide roller at the end of each unit, for additionally supporting a single belt. The top of the trough may be closed by removable deck plates 19 which, with hand rails 18, provide a walk-way. In Figs. 9, 10 (not shown), no separate distributing channel is necessary but the middle portion of the belt is supported by rollers (10). In Fig. 13 a driving or guide roller 20 for use at the ends of the conveyer has four blades 7 for reducing air pressure in the interior of the roller. Openings 8 allow air to draw the belt on to the surface of the roller. For preventing air from escaping at the longitudinal edges of the belt and preventing conveyed material from spilling over the belt and into the chambers (4), a chamber (21) is formed along the upper edge of the trough (2), Figs. 15, 16 (not shown). The conveyer belt may be substantially flat or guided in a tube.

Abstract: 1,203,158. Phase coincidence detection. VSESOJUZNY NAUCHNO-ISSLEDOVATELSKY INSTITUT METROLOGII IMENI D. I. MENDELEEVA. Nov.27, 1968, No.56232/68. Heading G1U. [Also in Division H3] A circuit for indicating phase coincidence of two waves comprises two tunnel diode circuits respectively producing pulses at the zero crossings of the waves and a coincidence detector to which these pulses are applied. In Fig. 2, one input wave U1 is applied to terminal 2. It operates a monostable tunnel diode circuit 18, the squarewave output of which is applied to a transformer 16 to produce spikes at the leading and trailing edges. The negative spike is selected by a transistor 25 and triggers a tunnel diode monostable circuit 7 producing a very narrow pulse. This is fed through a low threshold diode to a tunnel diode coincidence detector together with the output of a similar channel receiving the other input wave U 2 . The resulting output pulse if the pulses coincide is lengthened by a monostable circuit 38, 39 and used to fire a thyristor 51 which pulses a strolotron 47 to produce a flash at each coincidence. Correct operation can be checked by throwing switch 62, 63 to connect the A. C. mains supply to the two inputs.

Abstract: 1,162,106. Soldering. EUROPEAN ATOMIC ENERGY COMMUNITY. 16 Dec., 1966 [20 Dec., 1965], No. 56473/66. Heading B3R. [Also in Division H1] To connect a metallic conductor to a GeTe body of a thermo-electric generator, an iron film is deposited on the body and diffused into it. A film or foil of a suitable metal-e.g. gold-is then placed on the diffused zone surface and the conductor is pressed on to the film or foilcovered surface. It is then secured by heating to form what amounts to a soldered joint. It is stated that the iron previously diffused into the GeTe body acts as a barrier to further, and deleterious, diffusion from the film or foil or the overyling conductor. The iron film is of a thickness in the range 5 to 50 Á and is deposited on a ground and polished surface of the GeTe by vacuum or electrolytic deposition or by ionic plasma spraying. It is diffused-in by heating in argon or a nitrogenhydrogen mixture, and any residual iron on the surface is removed by grinding. After repolishing and de-greasing in trichlorethylene, the gold or copper is deposited to a thickness of 7 to 10 and the conductor is applied and held by a clamp during the final heating stage.

Abstract: 1331479 Measuring viscosity NETHERLANDS APPLIED SCIENTIFIC RESEARCH FOR INDUSTRY TRADE & COMMERCE 11 Dec 1970 [12 Dec 1969] 58927/70 Heading G1S The viscosity of a liquid is measured simultaneously in two capillary viscometers the sizes of the capillaries varying with temperature in a different manner in each viscometer so that the ratio of the two measurements is a measure of the temperature at which the viscosity is measured. In Fig. 1, (not shown), each viscometer comprises an outer body 1,1' and an inner body 3,3' defining therebetween a capillary 4,4'. The co-efficients of expansion of the bodies are such that size of capillary 4 varies in a different manner to that of capillary 4' with temperature. In one embodiment, bodies 1,1' and 3 are of one material while body 3' is of a different material. In another embodiment bodies 1 and 3' are of one material and bodies 1' and 3 of another. In Fig.3, each viscometer comprises a stator 6,6', the two stators being integral, and a rotor 7,7' having inclined grooves 8,8' leading from a central horizontal groove 9, 9'. Test liquid is passed under pressure down duct 11 into each viscometer where it passes along the capillary constituted by the space between the stator and rotor and out of discharge passages 12,12', 13,13'. The flow of liquid in each viscometer supports the rotor out of contact with the stator and rotates it at a rate proportional to rate of flow of liquid in the viscometer. Stators 6, 6' and rotor 7 are made of one material and rotor 7' of another material having a greater coefficient of expansion so that the ratio of the rates of rotation of rotors 7,7' is a measure of the temperature of the liquid under test.

Abstract: 593,733. Automatic control. SPERRY GYROSCOPE CO., Inc. Aug. 16, 1943, No. 13295. Convention date, Aug. 15, 1942. [Class 38 (iv)] [Also in Group XX] Attitude.-An electromagnetic erecting device for a gyro instrument comprises an alternating- current torque motor for applying torque about one axis under the control of voltages generated in an inductive pick-off device which detects tilt about an axis perpendicular to the firstmentioned axis. As shown in Fig. 1, wherein the rotor is supported with three degrees of freedom in a case 14 and vertical ring 13, and is spun by a three-phase motor whose stator windings 17, Fig. 4, are supplied by leads 19, 20, 21, the torque motor is of the squirrel-cage induction type of polyphase motor whose stator 26 is fixed'upon the vertical ring 13 and whose rotor 27 (consisting of spaced induction bars) is secured to the casing 10. The stator 26 is polyphase wound, with one of the windings 29, Fig. 4, continuously energized by inclusion in the circuit leads 19, 20, 21. The controlling means for the torque motor comprises a semicircular stator 30 secured to the vertical ring 13 and a secondary coil member 37 extending from the side of the rotor case 14. The stator 30 is supplied from the leads 19, 20 and has opposing polepieces 34 wound in reverse directions above and below the horizontal. Tilt of the rotor casing moves the secondary coil member 37 into the field flux of either the upper or lower sections of the semicircular stator 30 and the consequent induced output from the coil 37 energizes the other winding 43 of the torque motor to apply the corrective torque. An amplifier may be introduced between the pick-up secondary coil 37 and the winding 43. In a modification, Fig. 3 (not shown), the semicircular stator 30 includes only four curved pole faces, two above and two below the horizontal. To counterbalance the reactive torque about the axis of the case 14 and avoid consequent precession of the vertical ring 13, when the secondary coil moves from its normal position, a variable reluctance magnetic couple is provided consisting of a magnetic permeable core 44, Fig. 6, fixed to the vertical ring 13 and a permanent magnet 46 on one of the trunnions of the rotor case 14. The magnet is situated in an elliptical opening in the core 44 and, as relative movement occurs, the reluctance of the magnetic circuit is lowered to produce the counterbalancing torque. In a modification, a horseshoe magnet and permeable core are used.
