Title: Improvements in and relating to safety control devices for burners when firing furnaces
IPC: F23C99/00
Filed: 1954-04-27
Abstract: 755,457 Automatic circuit-breakers, thermal switches. RHEOSTATIC CO., Ltd., FLIGHT, T. N., and SAWYER, W. A. April 27, 1954, No. 12149/54. Class 38(5) [Also in Group XI] An automatic circuit-breaker in an electrical safety control system for a furnace burner (see Group XI), and serving to shut down the burner if a flame is not established in the furnace, comprises a bimetallic strip 7, Fig. 1, fixed to a metal block 8 on which a heating resistance 9 is wound, and the lower end 5 of the strip serves as a catch for engaging the end of an insulating bar 3 carrying a contact 4 and a resilient blade 2 pressing a contact 1 into engagement with the contact 4. The strip 3 is pivoted at its other end which is carried by an ambient temperature compensating strip 10. In the event of failure to establish the flame the heating resistance 9 will cause the bimetallic strip 7 to disengage the catch 5 from the arm 3, so that the latter will be drawn upwardly by a spring 14. The blade 2 is held, however, by the end of a push rod 15, the upward movement of which is restricted, so that the contacts 1, 4 become separated. The contact 1 is then held in engagement with a contact 16 through which an alarm circuit may be energized, and the heat stored in the metal block maintains the deflection of the bimetallic strip 7 so that the catch cannot be re-engaged until a safety or purge period has expired. When such period has expired the rod 15 may be pushed manually downwardly to re-engage the arm 3 with the catch 5. The control system also includes a bimetallic element 20, Fig. 2a, heated during the operation of the burner to hold open switches in the burner starting circuit for a predetermined time after each stepping of the burner. The switches comprise three contacts 24, carried by the bimetallic element 20, associated with three contacts 28, carried by an ambient temperature compensating bimetallic element 21. When the heating winding 22 is de-energized the contacts are held closed by a permanent magnet 27 carried by the strip 20, which attracts twin armatures 31, 32 carried by the strip 21, the relative inclination of the strips 20, 21 being such that the greater attraction is exerted on the armature 31. When the heating winding 22 is energized the warping of the strip 20 causes the three pairs of contacts to open with snap action, and on de-energization of the winding 22 the magnet 27 effects snap closure of the contacts. The temperature of the strip 20 at this instant is lower than that at which the contacts are opened due to the differential action of the magnetic attraction exerted on the two armatures 31, 32. The delay in closing the switches is variable by altering this differential action by adjustment of the relative inclination of the strips 20, 21 by a screw 35. Two of the contacts 24 are resiliently mounted and are so positioned that they engage the contacts 28 immediately before the engagement of the other contacts 24, 28.

A machine for delivering folded bendable articles, such as shopping bags and newspapers, from the top of a stack 14 comprises an elevating mechanism 36, Fig. 1, for lifting the stack so that the topmost article is adjacent an opening 30 in the front of the machine, and a coincontrolled means for displacing the topmost article so that the customer may grasp and withdraw it through the opening, such means including a rotary shaft 66, Fig. 9, which, when rotated through one revolution from the position shown, causes one or more flexible ejecting fingers 74 to sweep downwardly and backwardly over the topmost article in order to present at least part of the article to the customer. As shown for dispensing shopping bags 14, the insertion of a coin into a box (73), Fig. 2 (not shown), starts a motor (69) to drive, through a chain (68), the shaft 66 which carries a pair of flexible fingers 74 provided with rubber tips 75 for lifting up the handle 17 of the bag and, in addition, a wiper plate 76 and a set of wiper fingers 77 which serve to support the bag in its raised position. The bags in folded condition are stacked on a pivoted platform 19 which is guided for vertical movement along a post 32 by a pair of supporting arms 31 attached to a pair of belts 36 in tandem. The stack is urged upwardly on to spring-stops 54 and holddown fingers 59 by a tension spring 43 applied at the rear of the belts; if desired, weights may be placed on a spigot 45 above the spring. As the stack is moved upwardly, it is tilted by the spring-stops 54 against the fingers 59 which are secured to a vertically-movable plate 60 of a braking system. Upward movement of the plate 60 causes a pair of levers 80, one on each side of the machine, to rotate about a pivot 82 and thereby apply, through scissors action, brake shoes 86 on to drums 85 which are secured to ends of the pulley-shaft 40 for the belts 36. The shaft 66 is supported by the forward arms 67 of levers 80 and a pair of flexible fingers 64 secured to the plate 60 assist in dispensing the bag. A guard plate 78 hinged above the stack at 79 is also provided. To load the machine, a crank 44 is applied to the pulleyshaft 40 for depressing the platform 31 against the action of the spring 43. When newspapers are to be dispensed, the fingers 74 provide a leafing action.

Title: Improvements in or relating to electrographic transfer sheets
IPC: G03F7/34
Filed: 1961-04-06
Abstract: <PICT:0925168/IV(a)/1> A hectographic transfer sheet is made by applying a coating comprising oil or wax, fat and a hectographic ink on to a carrier made of a fat-absorbent material, e.g. paper, and passing the coated carrier over a heating surface or through a heating channel, which has a temperature higher than the melting temperature of the coating.  As shown, tissue paper 1, from a spool 10 is coated first by roller 12 with a composition 102 comprising oil, fat, wax and a hectographic ink, e.g. triphenylmethane dye, then, on the other side, by roller 18 with a composition 104 of wax or synthetic resin, finally, on the same side as the first coating, by roller 22 with a composition 103 of fat, wax and oil mixed with an easily water-soluble organic compound, e.g. dextrin, to form an adhesion layer.  The web is pressed on to the roller 22 by a controlled-pressure roller 24. Roller 22 is also adjustable relatively to a resilient rubber roller 23 which controls the thickness of the coating.  It is then passed through a chamber 26 containing a heating plate 28 and infra-red lamps 27.  Beneath the heating plate is a container 29 of volatile acid or base, e.g. ammonia, heated by the resistor 31. Vapours therefrom rise through the slots 34 in the heating plate into contact with the adhesion and ink coatings to improve their adhesion to, e.g. chemically treated gelatin. Specification 838,582 is referred to.

Filed: 1934-04-24
Abstract: 437,117. Washing-machines. SCHMID, C., 13, Meiningen Allee, Charlottenburg, Berlin. April 24, 1934, No. 12381. Convention date, April 26, 1933. [Class 138 (ii)] A device for agitating the liquid in a washing- machine comprises two cup-shaped members 8, 9 which are caused to recede from and approach one another alternately. The member 8 is integral with a cylinder 1 in which a piston 2 secured to the other member 9 works. The piston is moved in one direction against a spring 6 by fluid pressure admitted through a pipe 10, and at the end of its stroke automatically cuts off the fluid pressure supply. The piston is then moved in the opposite direction by the spring and at the end of its stroke re-opens the fluid pressure supply. The control means for the supply comprises a cylinder 3 which alternately closes and uncovers the supply and discharge ports 12, 13. As shown the piston is near the end of its (upward) stroke under the action of the spring. Further upward movement causes the lower end 7<b> of a hollow part 7<a> of the piston rod to contact with the enlarged lower end of a rod 4 carrying a pin 17 working in a stationary guide 16 and to which an end of each of two springs 5 is secured. The other ends of the springs 5 being secured to the cylinder 3. Upward movement of the rod 4 causes the springs to become horizontal and then to reverse their inclination thereby moving the cylinder 3 downwardly to open the ports 12 and close the ports 13. During the downward movement of the piston the rod 4 remains stationary until near the end of the stroke, the enlargement 4a is engaged by the upper end 7<c> of the hollow 7<a> and the rod 4 moves downwardly to raise the cylinder 3.

Title: Improvements in Means for the Control Electrically of the Signal Indicators used in connection with Mine Hauling Engines, Winding Engines and the like.
Inventor: FORSTER JOHN PERCIVAL
IPC: B66B19/06
Filed: 1916-09-01
Abstract: 104,828. Forster, J. P. Sept. 1, 1916. Mechanical telegraphs.-The signal indicators of a mine or like signalling system are re-set automatically when the winding-engine is started or stopped, by means of a commutator driven from the engine shaft and arranged to break the circuit of an inductance, thereby sending a surge of current through a magnet controlling the resetting-circuit. The coils of the inductance A are in circuit with the battery g, commutator D and brush f, contact n, and armature l; and an electro-magnet B is placed in shunt across the inductance A. When a signal is sent either mechanically or electrically, a magnet C is energized, withdraws a latch h, and allows a spring m to swing the armature l against the contact n. If the brush f is in contact with a conducting- segment of the commutator D, the magnet B and inductance A are energized, but the armature l is not sufficiently attracted to overcome the spring m. When, however, the engine starts, the circuit of the inductance A is opened, and the induced electromotive force fully energizes the magnet B, which attracts its armature l, closes the resetting-circuit q at the contact o, and cancels the signal. If the engine is running when the signal is given, the quick succession of makes and breaks at the commutator does not allow the current through the inductance A to build up until the engine has almost stopped, the action then being as described above.

Abstract: 528,132. Electromagnetic interrupters. STERN, W. April 27, 1939, No. 12689. [Class 38 (v)] A device for controlling flashing or other intermittent signals comprises a relay 7 which controls the duration of the cycle and a relay 13 which determines the length of the " on " periods of the cycles. Both relays have condensers 8 or 14 and fixed and adjustable resistors 9, 10, or 15, 16 in parallel with them, so that after the coil 7 or 13 has been disconnected from its source of supply, the condenser keeps it energized for an adjustable time. This time is greater in the case of the relay 7 than in the case of the relay 13. On connecting the lines 1, 2 to a source of supply, the relays are energized through contacts 6, 12 respectively. The.relay 13 closes at 18 the signalling circuit 3, 4. The relay 7 causes the contacts 6, 12 to open so disconnecting the relays from the lines 1, 2 but the condensers maintain their energization, until the contact 18 is released to break the signalling circuit and a little later the contacts 6, 12 are released to cause the whole cycle to begin again.
