Title: Improvements in and relating to pilot circuit protection
Inventor: HODGKISS JAMES WILSON
IPC: H02H1/00
Filed: 1956-05-25
Abstract: 853,304. Protective arrangements. METROPOLITAN-VICKERS ELECTRICAL CO. Ltd. May 22, 1957 [May 25, 1956], No. 16273/56. Class 38 (5). In a protective arrangement a D.C. pilot circuit is supervized by the application of an A.C. signal to the pilot wires for the operation of an A.C. responsive device when the pilot circuit becomes defective. In the intertripping arrangement shown, a trip relay 3 at station B is energized from a D.C. source 2 at station A when intertrip contacts 4 are closed. The contacts 4 are normally open and are interconnected with normally closed contacts 6. An A.C. source 5 is connected in series with the pilot circuit at station A and a winding 7 of a wattmetric induction-type relay WR is connected in series with the pilot circuit at station B, a further winding 8 of the relay WR is supplied from an external source. Under normal conditions, the windings 7 and S are energized and maintain contacts 9, 10 open. If the pilot circuit is interrupted or the wires 1 become short-circuited, the winding 7 is de-energized and contacts 9, 10 close after time delay produced by the braking action due to a permanent magnet (not shown) to complete a detecting, indicating, controlling or supervizing circuit 11. A reversal of the pilot wires will reverse the torque of the relay WR and cause the contacts 9, 10 to close.

Title: Mechanism for temporarily interrupting the sounding of an alarm
IPC: G04B23/03
Filed: 1962-04-30
Abstract: 982,189. Electric clocks. SUNBEAM CORPORATION. April 30, 1962 [May, 22,1961], No. 16473/62. Heading G3T. An electric motor driven alarm clock having an alarm movement controlled by an alarm mechanism which is movable between alarm wounding and alarm shutoff positions at preselected times, is provided with alarm delay mechanism, comprising a manual actuator supported by the movement and movable through a constant distance to move an alarm restraining means from an inoperative position to an alarm shutoff position, said alarm restraining means being operable to shut off the alarm independently if the said alarm mechanism, movable delay means operated by movement of the manual actuator holding the alarm restraining means in the alarm shutoff position, means driven by the clock to release the delay means from holding the alarm restraining means, and adjustable means controlling the release time for the delay means. The reed vibrator alarm 50 is normally freed for sounding at the preselected time through axial movements of the hour wheel 35 allowed by co-operating cam surfaces on this wheel and the alarm setting wheel 37. A pivoted lever 52 bearing on the hour wheel thus moves anticlockwise, Fig. 8, and carries an alarm shutoff member 51 into the alarm sounding position. The alarm may be restrained from sounding for a period by manual depression of a slide actuator 55 which by a projection 55c thereon moves an alarm restraining member 58 anticlockwise about a pivot 59 so that a lug 58c thereon engages the lever 52 and moves it back to the alarm shutoff position, Fig. 9. The alarm restraining member 58 carries pivotally a toothed sector 61 which has a catch 61a normally engaging a stationary spindle 64. On movement of the alarm restraining member 58 anticlockwise the sector 61 is released from the spindle 64 and spring-urged anticlockwise to a position such as that in Fig. 10 wherein a lug 61c on the sector engages an adjustable cam-shaped stop 65 carried by the spindle 64. Now upon release of the manual actuator 55, the toothed sector 61 moves into engagement with a pinion 41 of the time train and is driven anticlockwise until it disengages the pinion, whereupon the manual actuator 55 and the alarm restraining member 58 are returned to their initial positions under springs 57, 60. The position of first engagement of the sector 61 with the pinion 41, as determined by the cam-shaped stop 65, thus determines the delay period. Three different delay periods of five, ten, and fifteen minutes may be allowed for by adjustment of the spindle 64, which carries a disc 66 having faces 66a, 66b engageable with a fixed stop 45c to determine the maximum and minimum delays and a dimple 66c which can ride on to an intermediate fixed projection to determine the third period. Another manual actuatable means, not shown, which can permanently shut off the alarm, is provided. Specifications 892,124, 892,140 and 950,202 are referred to.

Abstract: 1,254,930. Container closures. CIBAGEIGY A.G. 28 March, 1969 [30 March, 1968; 23 July, 1968], No. 16500/69. Heading B8T. A tamperproof thermoplastics cap 3 for a container 2 having an annular bead 5 is formed by blowing hot air, e.g. from a jet 8, on to a reduced part 4b of a security ring joined by webs 6 to the main part of the cap, the part 4b being turned under the bead 5 by means of a roller 7. The webs 6 provide a failure line which may be present in the cap blank or may be formed by a notched roller-cutter at the same time as the roller 7 turns under the part 4b. The container 2 with the screw cap in position may be rotated, and similarly the support for the roller 7, in order to turn the part 4b under. A sensor may be used to detect when the cap part 4b is soft enough for the roller pressure to be effectively applied. The heat supply to the jet 8 may be interrupted, e.g. by moving the jet 8 away from the cap, as pressure is applied; or pressure may be applied at the same time as the heat is first applied. The rollers may themselves produce the necessary heat, e.g. by the raising of their rolling speed and their amount of slip. The screw-threads on the cap may be omitted, or may be formed against threads on the con. tainer neck. One of the webs 6 may be weaker than the others, Fig. 9 (not shown).

Title: Machine for the manufacture of bread rolls and loaves
IPC: A21C7/01
Filed: 1946-05-31
Abstract: 616,553. Making dough rolls. KREISKY, K. May 31, 1946, No. 16654. [Class 87 (i)] A dough roll is formed by sheeting a lump of dough between rollers 5, 6, Fig. 4, and then rolling-up the dough sheet between belts 16, 17 The rollers 5, 6 rotate at different speeds and in opposite directions to reduce the lump to a sheet having tapering leading and trailing edges which is engaged simultaneously by the receiving ends of the belts 16, 17. The adjacent runs 18, 19 of the belts are inclined downwardly, move in opposite directions, with the speed of the lower one greater than that of the upper, and diverge away from the rollers 5, 6. The lower belt 16 is supported on rollers 20, 21 and a bar 22, Fig. 7. The tension of the belt is varied by means of adjusting screws 30 which position the roller 20 in slots 29. The roller 21 is pivotally mounted about a bar 24 so that the weight of the roller serves to keep the belt taught. Additional pressure may be applied to the centre of the dough roll by a hump 60 on the bar 22. The amount of additoinal pressure is varied by altering the position of the hump by means of a lever 64. The whole of the lower belt and its frame pivots about the roller 21, and the angular position of the belt and frame, about the roller, is adjusted by screws 26 which abut against a fixed bar 27. The upper belt is supported by rollers 31, 33, 34, 37 and a bar 32, and the belt and its frame pivot about the axis of the roller 31. The pressure of the upper belt on the dough, due to the weight of the belt and its frame, is adjusted by means of a counterweight 41 slidably mounted on a bar 42. Due to the ability of the belt to rock about the roller 31 constant pressure is maintained on the dough roll during its formation. The tension of the belt is adjusted by altering the position of the roller 34, which is pivotally mounted on an arm 38, by means of a screw 39. The minimum distance between the receiving ends of the belts is limited by pins 45 which engage in slots 44 in links 43. This distance is adjusted by altering the angular position of a shaft 47 which carries discs 46 on which the pins 45 are mounted. The thickness of the sheet fed to the belts may be varied by adjusting the distance between the rollers 5, 6. Scrapers may be provided to remove dough adhering to the rollers. The dough roll is delivered down a plate 58. To smooth the surface of a dough roll or to increase its length or to modify the ends thereof, after leaving the plate 58 it falls onto a belt 69, Fig. 11, which passes it between a felt apron 74 and the lower run of the belt, where it is squeezed and smoothed, and then delivered at 87. The distance between the lower run of the belt and the apron is adjustable. The side edges of the apron at the outlet end may be titled up at an adjustable angle by means of fingers 83 to impart a sharper taper to the ends of the roll.

Title: Improvements in and connected with coil winding machines
IPC: H01F41/06
Filed: 1919-07-03
Abstract: 153,350. Igranic Electric Co., and Wright, S. R. July 3, 1919, Winding-machines.-To enable standard plain coil-winding machines, such as described in Specification 4230/15, to be used for winding conical coils, the traverse of the cotton guide is progressively shortened and lengthened from one end of the cone by means controlled by the movement of the wire guide, so that a band or cheek of cotton is built up at the large end of the cone and the coils of wire are bound and covered by coils of the cotton. A lever 17, Fig. 1, is connected at 20 to a bracket 23 carrying the cotton guide, and is pivoted at 18 to a bracket 16 operated by the usual cam. The other extremity of the lever 17 slides in a slotted bracket 25, which is connected by an arm 27 with a bracket 29 carried by the wire traverse mechanism. The cotton guide completes approximately two hundred traverses to one of the wire guide, and the gradual movement of the bracket 25 modifies the motion imported by the cotton cam to the lever 17 and the cotton guide. The slot of the cam operating the wire guide is shaped as shown in Fig. 8, so as to wind a succession of layers as shown in Fig. 5. Each portion of the slot makes the same angle with the base line 3 so as to maintain a constant velocity of the guide. Other shapes of slots may be used to wind coils of shapes other than strictly conical.

Title: Number transmission system for automatic telephone exchanges
IPC: H04Q3/42
Filed: 1949-06-23
Abstract: 676,880. Automatic exchange systems. TELEFONAKTIEBOLAGET L. M. ERICSSON. June 23, 1949, No. 16743/49. Class 40 (iv). In a signalling system in which a signalling device at one end connects various combinations of impedances, including rectifiers, to a transmission line, a receiver at the other end of the transmission line tests the line first with battery of one polarity and then with battery of the opposite polarity and sets a registering device in accordance with the results of these tests. In certain cases a further test may be made with increased battery voltage. As described, a subscriber's number sending device connects up resistances, rectifiers, condensers and a non-linear resistance in various combinations for signalling the digits of the wanted number to an exchange. As shown, Fig. 1, pushbuttons connect different combinations of condensers Cl, C2; rectifiers E1, E2; a gas discharge tube or silicon carbide non-linear resistance G ; and resistances r1 ... r4 which are all equal and so arranged that only one of them may be effective at any time. When the hook-switch K is operated only the set A is connected across the line and relays R7, R8 come up at the exchange, Fig. 2. Relays R4, R3, R5, R6 also come up. At this stage - 48 v. is fed to the b-wire and earth to the a-wire. When the subscriber pushes a button either a resistance is connected into the loop or the loop is broken due to the insertion of a condenser, an oppositely-poled rectifier, the gas tube or combinations thereof. Relay R8 being connected to - 24v. releases to initiate the successive falling off of relays R4, R3, R5, R6. In the case where the loop is broken R7 also releases to bring up R9. During the release time of R3, the potentials applied to the a and b wires are reversed. If now the loop is shortcircuited due to the connection of a correctlypoled rectifier by the push-button or if a condenser is connected across the line both relays R1, R2 operate (due to the charging current in the case of the condenser). If a resistance is included in the loop only R2 operates. If the loop is disconnected neither operate. R1 and R2 bring up R11 and R10 respectively. During the release time of R5 a further test of the loop is made with the original polarities applied to a and b. In the case where no disconnection is observed in the first test, relays R7, R8 test for a closed loop or a resistance loop and bring up R12 or R13. In the case where a disconnection was observed R9 replaces the - 48 v. source with a - 96 v. source which is sufficient to break down the gas tube if this is included in the loop and so bring up R7 and hence R12. The digits are therefore registered on combinations of relays R9 ... R13 over contact trees of which the digit is fed to the register REG when R5 releases. In the case of the subscriber hanging up none of the relays operates and lead n is earthed to initiate release
