Title: Methods and apparatus for determining unbalance in rotary bodies
IPC: G01M1/22
Filed: 1973-08-02
Abstract: 1380846 Measuring rotory unbalance electrically HOFFMANN GmbH Gebr [trading as HOFMANN KG MASCHINENFABRIK Gebr] 2 Aug 1973 [1 Sept 1972] 36774/73 Heading G1N The dynamic unbalance of a rotor 1 Fig. 6, e.g. the armature of an electric motor, is measured by a transducer 54 associated with a bearing for the rotor, and a signal for defining a reference angular position is produced by an inductive pick-up 5 forming part of the tank circuit of an oscillator 28, whose output is thus a series of A.C. bursts corresponding to the gaps between the teeth of the rotor 1, on which unbalance compensation can be effected. The A.C. bursts are converted to a pulse train 21 Fig. 7, and the pulses counted by 29 which is reset when the count is equal to the number of teeth on the rotor, i.e. eight as shown. The reset pulses 22, which form the angular reference signals for the unbalance measurement, are converted at 62 to two square pulse trains 91, 92 displaced by 90 degrees, which are combined at 63 with the unbalance signal to produce D.C. voltages at 64, 65 representing the X and Y components of the unbalance mass relative to the angular reference position. These are fed to logic circuit 71  which selectively closes one of four FET'S 76-79, depending on the rotor quadrant containing the unbalance mass. When the driving motor for rotor 1 is switched off, switch 30 is closed, the charge on capacitor 32 is fed through a thryristor 35, closed by a pulse from one of the terminals 58-61, and coil 33, so that rotor 1 is arrested by member 39 with the appropriate quadrant of the rotor located under milling tool 84, for removal of unbalancing mass.

Abstract: 1,064,373. Regulating. M.Y.A.M. SERRUYS and J.A. HARDY. Sept.19, 1963 [Sept.26, 1962], No.36858/63. Heading F1B. The flow of mixture in the intake pipe downstream of the carburetter is controlled by a pair of simultaneously actuated flap or cylindrical valves. The flap valves 11, 12, Fig. 1, which are mounted in a body 2 adapted to be clamped between the carburetter and intake manifold, are of part-cylindrical shape so that when fully open they form a continuation of the cylindrical portion of the mixture passage 4. The valves are opened by a diaphragm 38, responsive to suction upstream or downstream of the valves 11, 12, and are urged closed by a tension spring (28), Fig. 2 (not shown) connected to an arm (27) pivoted on a plate 24 connected to the spindle of valve 12. The valves are interconnected by a link (25) and their closed position is determined by an adjustable stop 30. In Fig. 8 (not shown) the valves comprise rotary cylinders (71), (72), interconnected by toothed sectors 77 and arranged so that when fully open their openings (78) form a cylindrical passage which is a continuation of the cylindrical passage of the carburetter and intake manifold. The valves are actuated by a suction responsive diaphragm and their closed position is determined by a resilient abutment 82 co-operating with a stop.

Abstract: 412,978. Artificial teeth. FISCHER, V. J., 39, Place St. Felix Ó Beziers, HÚrault, France. Dec. 31, 1932, Nos. 36998 and 36999. Convention dates, Dec. 31, 1931 and July 21, 1932. [Class 81 (ii).] Artificial teeth each having a complete shell of gold and a core of ceramic material or light metal are formed by providing cores a, fitted with pins b, with a wax coating of a thickness varying according to the expected wear of the tooth at any point, investing the coated core in a metal casting mould, burning off the wax so as to leave the core suspended by its pins in the cavity in the investing body, as shown in Fig. 7, and then applying a gold coating by casting. The wax control cores are supplied to the dentist, who may add or remove wax as required and may connect several teeth together, using a hot spatula. The cores are set up on a plaster model of the jaw c and are held in place by means of a pad d of clay mixed with glycerine into which the pins are pressed. The projecting portions of the pins, which may be made of stainless steel, are cut off level with the surface of the gold coated teeth and the exposed ends may, if desired, be coated with solder. For the commercial manufacture of the wax coated cores, a number of cores are placed in connected cavities in a two-part mould 1, 2, Fig. 1. Each core carries two pins which pass through corresponding passages in the mould part 2 and one of these pins, which is formed with a bevelled end and a notch, is engaged by a spring-pressed pin 6 so that the core is correctly positioned relative to the walls of the cavity in the mould. Hard wax is then poured into the mould, and after cooling and opening of the mould, the wax coated cores are removed from the mould part 2 by pressing on the externally projecting portions of the core pins by means of a rod with pins entering external recesses on the mould, inserting a plate e, Fig. 3, and lifting off the cores. Reference is made to known constructions wherein an ordinary artificial tooth coated with wax is held in place in a casting mould by means of gold wedges, or an artificial tooth, with or without undercut notches, is coated with gold by electrodeposition.

Title: Desensitization of alloys to intergranular corrosion
IPC: C22F1/00
Filed: 1974-08-23
Abstract: 1472446 Altering physical properties ROCKWELL INTERNATIONAL CORP 23 Aug 1974 37177/74 Heading B3V  An alloy susceptible to intergranular corrosion following exposure to a sensitizing temperature is desensitized by shot peening a surface thereof to a degree sufficient to break up the grain structure and eliminate continuous grain boundaries before exposure to the said temperatures. Thus instead of continuous grain boundary carbide precipitation formed at the sensitizing temperature, innocuous precipitation of carbides occurs throughout the cold-worked portion of the alloy. Stainless steels, aluminium, copper and magnesium alloys, nickel-rich alloys, die-cast zinc, Cr-Mn and Cr-Mn-Ni steels may be treated to a depth of at least 1-5 mils by ceramic or steel shot. Peening coverage beyond ordinary requirements is necessary, as determined by a peened surface content of not less than 0À5% ferrite and minimum eddy current reading of 43 when the unpeened surface has a reading of 40. Stress corrosion and fatigue failure are also prevented by this more severe shot-peening process. The process may be applied in areas to be welded.

Filed: 1929-12-07
Abstract: 350,497. Separating solid materials. HOLMES, C. W. H., Deneside, Alverstone Avenue, Low Fell, and BIRTLEY CO., Ltd., Birtley, both in Durham. Dec. 7, 1929, No. 37626. [Class 117.] Apparatus for separating mixtures of substances, e.g. coal and shale, comprises a rotating cylinder 1 of glass or other resilient material on which the substances fall after sliding down an adjustable inclined shoot 24. The cylinder 1 which is mounted at the lower part of a casing 23, is preferably driven by the variable speed gear 9 and is kept clean by a brush 21. The separated products are collected by shoots 36, 37. The adjustable shoot 24 is preferably formed of metal and may have transverse corrugations substantially of the dimensions of the particles under treatment. Longitudinal, vertical, and angular adjustment of the shoot is provided by the set-screws 29, 28. The materials are fed to the shoot from the hopper 32 so that the particles have a free trajectory and are separated by the differences in the sliding friction on the shoot and the rebound from the cylinder. Multiple collecting shoots may be provided for products of varying purity.

Title: Improvements in or relating to microphones
IPC: H04R21/02
Filed: 1929-12-09
Abstract: 340,398. Microphones. COVENTRY AUTOMATIC TELEPHONES. Ltd., and TWEATS, J. A., of General Electric Co., Stoke, Coventry. Dec. 9, 1929, No. 37696. [Class 40 (iv).] The main diaphragm of a microphone comprises two rigid discs 1, 2 clamped between nuts 4, 5 on a centre piece 6 and kept apart at their peripheries by a turned up edge or edges which clamp between them a flexible disc or annulus 3 of silk &c. The outer surfaces of the discs 1, 2 are slightly concave and the periphery of disc 3 is clamped to the casing 19 by a plate 24 and spring ring 25, a paper &c. washer 26 being interposed between the plate 24 and disc 3. The centre piece 6, which carries the moving carbon electrode 7, has clamped between it and nut 5 the auxiliary diaphragm 8 and washers 9, 10. The diaphragm 8, which is preferably made of metal, has its edge clamped between the cylindrical body 11 of the granule chamber and a ring 12, the edge of resilient washer 10 pressing on this diaphragm so as to confine the bending thereof to an annular portion near its edge. The rear fixed electrode 13 is mounted on a support 14 carried by a member 15 which is clamped between body 11 and a cap 16 but insulated therefrom by washers 17, 18. The member 15 is secured to casing 19 by a nut 20, insulating washers 21, 22 preventing metallic contact between this member and the casing. The inner surface of body 11 is so shaped that the carbon granules cannot break the connection between the electrodes in any position of the microphone. The microphone is mounted between a bent spring 23 secured under nut 20 and a flexible plate 28 attached to plate 24 by a spring ring 29 so that there is no rigid connection between the microphone and its mounting. Such an arrangement will prevent howling due to interaction between the receiver and microphone when the latter is employed in a hand-combination set.

Patent GB-1085023-A (GB)
Title: Improvements in or relating to winding machines
IPC: B65H63/06
Filed: 1964-09-16
Abstract: 1,085,023. Winding machines. W. REINERS. Sept. 16, 1964 [Sept. 21, 1963], No. 37792/64. Heading D1J. A thread winding machine having a knotting device 1, Fig. 1, for tying thread ends together, includes means to eliminate the winding-in of a knot formed with a doubled thread, said means including a sensing member 3, and means 4 controlled by the sensing member 3 to sever the thread upon detection of a doubled thread end, and delay means preventing the severing means 4 from cutting the thread in response to the sensing member 3, sensing a knot k. To exclude the effects of the knot k from the sensing member 3 there may be interposed between the sensing member 3 and the thread-cutting device 4 means by which the speed of response of the thread-cutting device 4 is retarded, i.e. by means of a delaying device installed in the operating current circuit of the cutter which permits the cutter to respond only when the measured value has exceeded the specific value for a specific period, or the cutter itself may be formed as a delaying member, for example in the case of electromagnetic actuation it is provided with a high inductance. If the thread dimension to be ascertained is a volume measurement this is preferably effected capacitatively, or if a thickness measurement, it is preferably effected photo-electrically. In Fig. 2 the device senses the thread thickness. The thread F slides on a glass prism 38. Light rays from a lamp 34 are rendered parallel by a lense 35 and are then split in prisms 36 so as to produce vertical and horizontal beams. These beams produce on each of two photoelectric cells 31a and 31b a shadow of a width corresponding to the thread thickness. If two threads are inserted in the slot, the two threads lie side by side on the glass prism 38, so that two shadows are produced on the photo-electric cell 31a while on the photo-electric cell 31b only one shadow is produced. The voltage then occurring at the points d and c of a bridge circuit is amplified in the amplifier 27 and controls an electro-magnet 20 by which the thread-cutting device 4 is actuated. In Fig. 2 a switch 22 is so coupled with the operating and control means of the winding machine that it interrupts the supply lead to the amplifier 27 during those times that the thread is being inserted into and withdrawn from the slot 11. Thus the switch 22 has the effect that the amplifier 27 can be influenced by the voltage occurring at the bridge points d and c only when a measurement is being effected. In both embodiments the knotted thread is passed through the sensing device for a temporary period only after the knot has been tide, the temporary path being indicated by the full line F and the normal path being indicated by the broken line F1.

Title: Gymnastic parallel bar
IPC: A63B3/00
Filed: 1973-08-09
Abstract: 1403132 Gymnastic apparatus JANSSEN & FRITSEN BV 9 Aug 1973 37811/73 Heading A6M A gymnastic parallel bars apparatus includes two cross bars at different heights supported by poles 1, 2 at each end of the cross bars, each pole 1, 2 being supported by tensioning means e.g. a cable or chain which engages the upper end of the pole and which extends obliquely away from the pole with its ends 6 anchored to the ground, and guide devices 5 mounted on the long and/or short poles 1, 2 through which the respective cable 4 extends, the construction and arrangement being such that each guide device 5 can be displaced along its cable 4 so that the associated pole is rotated about its lower end to alter the horizontal spacing between the cross bars, the guide device 5 then being locked to the cable 4. As described the longer poles 2 are supported by fixed cables 7, 8 and the shorter poles 1 are supported by cable 4 and guide device 5. Each pole 1 has a pin 9 which projects into a larger recess 10 in a bottom plate 11 to allow the poles 1 to be displaced sideways, rotating about their bottom ends. In a first embodiment (Fig. 1) the guide device 5 consists of a frame 12 carrying a pair of guide wheels 13 for the cable 4. The frame 12 has a tongue 20 with a fixing aperture located at the intersection of the projected lines (shown dotted) of the cable 4. A threaded rod 15 is rotatably mounted in a sleeve 17 on the frame 12 and engages a nut 14 fixed to the cable 4. Thus rotation of the rod 15 by knob 16 displaces the frame, pole and cross bar with respect to the cable to alter the spacing of the cross bars. In a second embodiment (Fig. 5) the cable 4 passes for a complete turn around a guide wheel 13 mounted in the frame 12. The wheel 13 can be rotated by knob 24 to alter the spacing of the cross bars, the wheel 13 then being locked by a pressure pad 22. In a third embodiment (not shown) the cable 4 passes through a curved passage in a guide block and is locked by a pressure pad engaging the cable.

Abstract: 1405963 Food treatment R GARCELON 14 Aug 1973 [24 Aug 1972] 38372/73 Heading A2D [Also in Division B8] An apparatus for the continuous treatment of products such as food products comprises a tunnel and trays for conveying the products being treated through the apparatus 1, which trays move in the tunnel along a treatment path from an inlet towards an outlet at various levels, successively at one level in one direction and at the following higher level in the opposite direction, the change of level and direction of movement being achieved by a first level-switching device at the inlet end of the tunnel, and a second level-switching device at the outlet end. The trays in moving from the beginning of the treatment until its end, move substantially horizontally and parallel to themselves, the arrangement being such that when the trays arrive at the end of the treatment path at the end of the upper stage, the trays due to a switching action assume successive positions which are more and more inclined until the trays are in a vertical position and the treated products then leave the trays and are discharged from the apparatus and the trays descend to an end point of the descent stage where they are urged to adopt a horizontal position, an upwards returning device guiding the trays to the inlet of the tunnel. The trays may be provided at one end with a first shaft pivoted to two parallel chains moving the trays along the treatment path, these chains being located on either side of the path and supported by chain sprockets. The trays may be provided at their other end with a second shaft supporting two rollers at its ends, each rolling on a rail over the path followed by the trays. A suitable apparatus is shown in Figure 1 and comprises a tunnel 1, inlet 3 for a treatment medium, an air temperature regulator 4, fans 5, product inlet and outlet 9 and 32 respectively and trays 10. These trays moving by the chain-rail means indicated above, carry product from inlet 9 via the serpentine path upwards to the end 20 of upper level 19 wherein a switching means 60 urges the trays to a vertical position thus discharging the treated product to conveyor belt 31 and hence outlet 32. Switching devices are provided at the ends of the levels 11 to 19 so that the trays may be horizontal and parallel to each other during the passage of the trays to end 20. Further switching devices are provided so that the trays, vertically orientated after end 20 may be returned to inlet 9 in a horizontal orientation so as to accept further quantities of products to be treated. The treatment may comprise drying, cooling or smoking.
