Title: Improvements in or relating to apparatus for indicating and/or recording the rate of feed of granular materials
IPC: G01F15/07
Filed: 1920-12-14
Abstract: 177,580. Lea, J. E. Dec, 14, 1920. Output of granular and like materials, measuring.-To indicate the rate at anv given moment at which a granular material is being fed or delivered, as to a furnace in connection with a mechanical stoker, an indicator marked or calibrated to indicate volume or weight is operably coupled to the feeding-mechanism. The indicating-device may be under the control of the driving-axle of the chain grate of the stoker and of the movement of the door regulating the opening to the furnace, or of the speed of the driving-mechanism for the ram that feeds the material forward, and of the mechanism for effecting a variation of the stroke of the ram. The invention also includes arrangements in which the area of the orifice or of the stroke of the ram remains constant. The indicating- device may be represented by a voltmeter calibrated to read volume or weight, or by a mechanically-operated speedometer similarly calibrated. In the arrangement shown, the axle g of the chain grate drives a pinion on the axle e, the rotation of which is communicated through gearing to a friction disc a spring-pressed against a roller i. This roller is movable along a shaft h under the influence of a balancing weight or spring i<2> at one side, and a rack k attached to a cable i<3>, j<4> at the other, the rack moving in synchronization with the door of the boiler furnace. The speed of rotation of the roller i is thus determined by the volume or weight of material passing into the furnace. The roller i drives a dynamo m either directly or through a roller l and chain gearing l<1>. In circuit with the dynamo is a voltmeter n calibrated so that it, pointer reads off the volume or weight of material passing info the furnace. The pointer may be provided with a pen adapted to mark on a clockdriven chart. Where a mechanically operated speedometer is employed, it is driven by the pinion l through a flexible shaft. For a mechanical stoker of the reciprocating ram type, the friction disc and roller are not necessary parts of the apparatus when the stroke of the ram is fixed; in this case, the speedometer will be actuated by the ram shafting only. Specifications 11459/14 and 118,333 are referred to.

Title: Improvements relating to automatic timing devices
Inventor: HOUCHIN JOHN PHILIP WYNN
IPC: G05B19/02
Filed: 1957-11-12
Abstract: 904,859. Automatic timing devices. ELECTRIC & MUSICAL INDUSTRIES Ltd. Nov. 12, 1958 [Nov. 12, 1957], No. 35222/57. Class 118. In a television programme timing device, seconds timing pulses are fed to the units, ten, and hundreds uniselectors B, C, D in a decade counter. A group of ten-way selector switches E1, F1, G1 are connected to the counters, each having its ten studs connected individually to ten corresponding studs on one bank of the corresponding uniselectors B, C, D. The movable contacts of the switches E1, F1 are connected to the wiper of the uniselectors C, D respectively. The movable contact of the switch G1 is connected to a relay R1, the other side of which goes via a voltage source S to the wiper of the uniselector B, to complete an energizing circuit for relay R1. The arrangement is such that the relay R1 is only energized when the counters are in a combination of states corresponding to the time set up by the selectors of the switches E1, F1, G1. The relay R1 can be used to generate a visible or audible signal or may be used to initiate automatic operation of a programme source, such as a tele cine projector. Further relays and groups of switches, e.g. R2, E2. F2, G2 may be connected to other stud banks on the uniselectors in a similar manner to that described above. The counters may be other than stepping switches, for example, multicathode gas discharge tubes, and the switches E, F and G may he operated automatically in response to information stored on, for example, paper tape.

Title: Improvements in or relating to measuring physical properties of elastomeric materials
IPC: G01N11/16
Filed: 1971-07-27
Abstract: 1298788 Measuring viscosity electrically B F GOODRICH CO 27 July 1971 [28 July 1970] 35269/71 Heading G1N The cure curve of an elastomeric material is obtained by placing a sample of the material in a conically-shaped, serrated cavity 26, Fig. 1 in a block 25, into which is inserted a coneshaped, serrated rotor 27 which is oscillated through a controlled angle, the sample being maintained at a controlled temperature whilst the torque on the driving shaft 31 is measured by a strain gauge transducer 43 and the maximum torque for each oscillation is recorded on a chart. To compensate for shrinkage of the test material during the test, the block 25 and the rotor 27 are pressed together by a linearly increasing pneumatic force supplied by cylinders 20 mounted on a fixed bracket 13 and pistons 21 attached to the ends of block 25, which is slidable on pillars 29, the initial spacing being determined by a limit switch LS1. The test is initiated by manually controlled switches which cause pistons 21 to raise the block 25 until switch LS1 is operated. After a predetermined delay, an integrator circuit, Fig. 4 (not shown) is energized to feed an electricalpneumatic pressure transducer which increases the force exerted by pistons 21 linearly. The  instant for energizing the integrator circuit may alternatively be determined by differentiating the torque value and delaying energization for a predetermined interval after minimum torque is passed.

Title: Improvements in or relating to the manufacture of non-woven fabrics
Inventor: FAIRFULL ANDREW EWAN SPOWART
IPC: D04H1/74
Filed: 1962-09-18
Abstract: A bonded non-woven fabric is produced by interposing a fibrous interlay between two fibrous webs, the fibres of the interlay being selected so that at least some of the fibres are less tenaciously bonded with a given bonding agent than those of the fibrous webs, impregnating the composite web with this bonding agent, and after setting the agent, splitting the web along the plane of the fibrous interlay.  The residual fibres of the interlay may provide a soft texture to one surface of each of the resultant fabrics; if this is not required the fibres may easily be removed by brushing.  The bonding agent may be viscose in which case the fibrous webs may be of viscose rayon fibres and the interlay may consist of or include fibres of polyesters, polyamides, polyacrylonitrile, polyacrylates, polymethacrylates, cellulose triacetate or polypropylene.  If the selected bonding agent is a natural or synthetic rubber the fibrous webs may be formed of fibres of polyamides, polyesters, polyacrylonitrile, polyacrylates or polymethracrylates and the interlay may include or consist of viscose rayon, polypropylene or polyethylene fibres.  If the selected bonding agent is an epoxy resin the fibrous webs may be formed from fibres of viscose rayon and the interlay may include or consist of cellulose acetate fibres. Splitting of the composite web is facilitated by consolidating the individual fibrous webs, e.g. by winding up with paper sheet followed by unwinding.  Specification 827,370 is referred to.

Title: Improvements in or relating to signalling arrangements in standing micro-telephone instruments
IPC: H04M1/02
Filed: 1959-10-26
Abstract: 918,275. Telephone sets; substation circuits. TELEFONAKTIEBOLAGET L. M. ERICSSON. Oct. 26, 1959 [Nov. 5, 1958], No. 36206/59. Class 40 (4). In a standing microtelephone set (Fig. 1) having a receiver 8 in the upper part of the handle and a microphone 9 in the foot, a sound producer 1 responsive to audio-frequency currents is provided in the handle or the upper part of the foot and communicates with a funnel 2, or a resonator (Fig. 2, not shown), in the handle communicating with the sound producer 1. The sound producer 1, which may be a small loud-speaker, is acoustically matched to the funnel 2 or the resonator, and may be actuated by an audio-frequency current (for example of 2000 c.p.s.) transmitted from an exchange, the sound producer 1 being connected in series with a condenser across the line wires in the manner usual for a bell. In a modification ringing current (e.g. of 25 c.p.s.) from an exchange modulates the oscillations produced by a transistor oscillator in the telephone set and the modulated output is fed to the sound producer 1. As shown in Fig. 3, the speech circuit is a conventional one with impulse springs 16, 17 and dial off-normal contacts 18, 19, which is connected to the line wires a 1 , b 1  by operation of the hook-switch contacts 11 to 15 when the telephone is lifted up. In the rest condition these contacts connect up the signalling circuit shown on the left of the line A-B. Condenser C1 is charged by the positive half-cycles of the ringing current and is short-circuited by rectifier L during the negative half-cycles. Directcurrent pulses are thus delivered from C1 to the transistor TR so that current flows in the collector circuit and through the sound producer S, positive feedback being provided by the transformer N. The output applied to S consists of a carrier and two sidebands and two series-connected resonators are provided in the handle of the telephone set (instead of the funnel 2) which resonators are tuned to the respective sideband frequencies. The input impedance of the lower of the two resonators is matched to the output impedance of the sound producer.

Abstract: 1,106,386. Balancing vehicle wheels. NATIONAL RESEARCH DEVELOPMENT CORPORATION. 11 Sept., 1964 [13 Sept., 1963], No. 36249/63. Heading B7C. [Also in Divisions B3 and F2] In apparatus for the dynamic balancing of a wheel 42 (Fig. 4) of a vehicle in motion, a mass 5 is mounted between two gear-wheels 33, 34 (Fig. 3) rotatable relative to each other and to the wheel about the axis of rotation of said wheel, or an axis parallel thereto, radial slots 40 on the gear 33 engaging pins 41 in the mass 5 to allow only radial sliding movement therebetween, and a peg 9 on the mass 5 engaging an eccentric circular cam slot 10 in the gear 34 so that relative angular movement between the gear 33 and the wheel 42 moves the mass 5 angularly of the wheel, and relative angular movement between the gears 33, 34 moves the mass 5 radially of the wheel. Fig. 3 shows one of a set of balancing units mounted with equal spacing round a pitch circle of the wheel with the balancing masses 5 identically positioned relative to the axes of their respective units. The gears 33, 34, which may alternatively be internally toothed, have slightly different numbers of teeth, and mesh with identical pinions 35 on a shaft 36 carrying a star-wheel 37. When a solenoid-controlled striker 38 on the vehicle chassis intercepts the star-wheel at each revolution of the wheel, the gears 33, 34 are given a differential rotation causing a spiral movement of the mass 5. This is continued until a sensor 39 indicates a minimum out-ofbalance force, the driver then causing the striker 38 to be withdrawn. The star-wheel may be replaced by an air turbine.
