Title: Improvements in the grinding and polishing of glass
IPC: B24B7/24
Filed: 1951-05-11
Abstract: 697,688. Grinding and polishing sheet glass. GLACERIES DE ST. ROCH. May 11, 1951 [May 23, 1950] , No. 11206/51. Class 60. A continuously - moving sheet or ribbon of glass 1 is ground or polished on one or both faces by tools which receive reciprocating movements in the longitudinal direction of the glass so that the traction forces on the glass due to the displacement of one tool is counterbalanced by a simultaneous displacement of another tool in the opposite direction. In the preferred embodiment, the glass ribbon 1 is acted upon by tools supported from beams A3, D2, C2, B2 &c. which are arranged in groups of four. These groups may be allowed to travel in step with the glass, e.g. towards the right in Fig. 6, while the trailing beams D2, D1 at the left of each group are displaced against the direction of travel of the glass to become the leading beams of the following group, this process being repeated with the beams C2, C1 and so on. The movement of the glass may be assisted by a resultant force from the movements of the beams, the groups being displaced to the right at a higher speed than the glass. The movements of the beams are obtained by connecting them in order to four chains 15, 16, 17, 18 each of which is driven by a differential 19 the two sun wheels of which are driven by a gear train 23 and an eccentric 25, respectively. The four eccentrics are keyed to a shaft 26 at 90 degrees relatively to one another and are connected to the differential through an arm 27, Fig. 8, and a lever 28. By this means all four chains receive a continuous movement through the gears 23 and an intermittent reciprocating movement through the eccentrics. Both the gears 23 and the shaft 26 are driven by a motor 20. The use of eccentrics produces a sinusoidal reciprocatory motion of the beams, but an irregular motion may be obtained by connecting the lever 28 to the differential through a ratchet drive. The movements of the beams.may be selected so that each beam reaches a position in which it may be taken out of operation for maintenance after a predetermined time. Both faces of a ribbon of glass may be polished simultaneously by arranging the beams in vertical pairs which receive opposite transverse reciprocations.

Title: An improved means for loading coal and dirt into skips
IPC: B66B17/14
Filed: 1956-04-13
Abstract: 826,410. Wheeled skips handling materials. QUALTER, HALL & CO. (SALES) Ltd., and LEECH, A. April 12, 1957 [April 13,1956; Nov. 14, 1956], Nos. 11342/56 and 34824/56. Class 78 (4). The body of a container 4 receiving spoil in a mine is automatically tipped about an axis 14 relatively to its underframe 10 when the container is moved from the position A in which it is loaded to a position C so that the contents of the container are discharged into the skip 1 of a skip hoist. The body 6 is normally supported by rollers 5 engaging a track 6 between the rails for the underframe 10 and inclined at the discharge point so that the body rocks clear of an end gate 15 supported by cheeks 16 from the underframe 10. Two containers 3, 4 are shown serving the two skips of a skip hoist and are moved by cables 21 passing to sheaves 23 each driven from a variable-speed motor or from a motor 25 through a variable-speed reversing gear. In an alternative construction a single cable 21 passes round a sheave 23 to join the two containers 3, 4 which run on a track inclined towards the shaft so that the weight of the spoil in the loaded container drives that container towards the discharge position under the control of a brake on the sheave 23. In still a further construction the containers 3, 4 are driven by rams. A single skip running on an inclined track may be counter-balanced by a balance weight. Catches controlling the motion of the containers may be controlled in conjunction with the movement of the skips 1, and a weightbridge 19 may measure the charge. Sliding gates 26, 29 form an air lock to the shaft. The containers 3, 4 are loaded through a pair of side-by-side shoots 9 fed by a laterally moving shoot 8 receiving material from a conveyer 2. The skips are discharged through fixed shoots 7.

Title: Radio receiving arrangements
IPC: G01S1/02
Filed: 1974-03-14
Abstract: 1498026 Direction finders ELLIOTT BROS (LONDON) Ltd 4 Dec 1974 [14 March 1974] 11481/74 Heading H4D The Specification describes a homing indicator receiver arrangement associated with a communications receiver which may be V.H.F., F.M. for use on, e.g. an aircraft, wherein the homing indicator RF and IF circuits are synchronized to the separate communications receiver RF and IF circuits using common local oscillators to drive the respective frequency changing circuits therein, the output from the homing indicator receiver being fed at IF to a mixer which acts as a synchronized detector and produces an output signal which is fed to a known homing indicator. The D.C. output from an AGC detector connected to the input of synchronous mixer is connected to one input of a D.C. comparator circuit along with the D.C. output signal of said mixer so that an output is produced to actuate an alarm circuit on detection of, e.g. lack of equality between these signals which would occur on the homing indicator receiver receiving a communications signal different to that received in the communications channel due to, for example a defect in the homing channel circuitry. As described, the communications receiver is connected to high gain antenna 1. Dipoles 5, 6, located symmetrically on the aircraft to have differing radiation patterns are connected alternately at low frequency by switch 7 to homing receiver 8. Mixing circuit 10, comprising two mixers which are switched in quadrature and have outputs full wave rectified and summed to define the phase of the low frequency homing signal, produces an output which is filtered at 12 at the switching frequency and applied to homing indicator 13 which may be a meter or an aural device. In another embodiment, the arrangement may receive A.M. communication signals. The arrangement allows the wider bandwidth required for homing detection to be provided while the narrower bandwidth of the communications receiver is retained.

Filed: 1962-03-27
Abstract: 964,136. Automatic voltage control. DECCA Ltd. March 21, 1963 [March 27, 1962], No. 11638/62. Heading G3R. A voltage regulator for a self-excited alternator having stator windings 10, 11 and field windings 15, 16 includes a transistor 22 in series with the winding 16. The field windings are energized from the alternator output over a transformer 13 and full wave rectifiers 17,18 and the base of transistor 22 is connected to a potentiometer 24 having one end connected to a smoothed direct potential supply derived from the rectifiers 17, 18 over a rectifier 26 and a capacitor 27, the other end being connected to a series of Zener diodes 30. A direct voltage of opposite polarity to that produced by the rectifiers 17,18 is derived from the alternator output by way of the transformer 13 and full-wave rectifiers 32, 33 and is applied to the Zener diodes 30. The base current for transistor 22 is drawn from the source 26, 27 and is sufficient to render the transistor fully conductive when the output voltage of the alternator is below a pre-determined value, so that the field winding 16 is then fully energized; when this value is exceeded the Zener diodes are rendered conductive by the increased voltage at the rectifiers 32, 33 and the transistor 22 is cut-off to de-energize the winding 16; the output voltage of the alternator is thus maintained constant at a value such that the Zener diodes 30 are changing from the conductive to non-conductive state or vice-versa.
