IPC: B23P15/40
Filed: 1961-05-06
Abstract: 908,425. Creasing-machines. FLOSEAL CORPORATION. May 6, 1961, No. 16555/61. Class 100 (2). [Also in Group V] A mould for producing creasing dies of the type used in making cartons has a main body of thermosetting resin in which are grooves adapted to hold frictionally the creasing rules of the die being moulded. As shown in Fig. 1 conventional wooden furniture pattern 1 holds creasing rules 4 between blocks 3. As shown in Fig. 4 mould backing panel 9 comprising parallel steel plates 11 connected by resin-impregnated paper walls 12 forming hexagonal cells and knock-out pins 16 frictionally retained by holes in plates 11 is placed in pattern 1, all exposed surfaces being coated with a parting medium. Thermosetting resin 21 is poured into the pattern within side-walls 6 so as to cover the heads 18 of knock-out pins 16 and enter sides 14 of backing-plate 9, weight 22 being used to ensure heads 18 are flat against blocks 3. When the resin has cured the mould comprising resin plate 21 with grooves to take rails 2 and rules 4 and backing-plate 9 with knock-out pins 16 is ready for use when rails 2 have been replaced. The working dies are produced from the mould as illustrated in Fig. 6. Rules 4, for the die being made, have U-shaped recesses 29 and are fitted into the grooves in the mould with tie-rods 30 in place with small pieces of thin compressible material, such as chipboard 32, under them. Rules 4 and exposed surfaces are covered with parting medium and epoxy compound 35 poured into the mould within rails 2 and level with the  upper edge of the rails. When the compound 35 is set the finished die is removed from the mould by a simple press (Fig. 7, not shown) which simultaneously presses on shanks 17 with the mould held in the inverted position. Adjustments may be made after curing of the die by tapping the rules against the compressible seat provided by chipboard pieces 32.

Title: Improvements in fluid pressure actuated electric switches
IPC: H01H33/30
Filed: 1940-12-06
Abstract: 544,685. Actuation of switches. BRITISH THOMSON-HOUSTON CO., Ltd. Dec. 6, 1940, No; 17359. Convention date, Dec. 6, 1939. [Class 38 (v)] A circuit breaker is actuated by a piston, pressure-fluid being directed to either side according to the position of a diverter-valve, movement of which controls also the operation of a main valve. In the example, 55, 56 are supply lines for operating current, and 54 the power line to be controlled. With the breaker 50 in the closed position and with the main and diverter valves 19, 30 in the positions shown. to which they are biased, opening is effected by closing a hand switch 62, completing a circuit from line 56 through fixed'contacts 70, bridged by a segment of the arm 65, and solenoid 27 of main valve 19 to the other line 55. Pressurefluid is admitted by the valve 19 through conduit 18 to the underside of the breaker-operating piston 49 to separate contacts 53. Arm 65 is moved at end of travel of piston to open contacts 70, thus de-energizing coil 27 and closing main valve 19. To close the breaker, hand switch 63 is closed, completing a circuit from line 56, contact 58 of an overload relay 57, solenoid 35 of diverter, and fixed contacts 71 bridged by another part of arm 65, to line 55. The diverter valve 30 rises arid fluid passes by conduit 17 to the top of piston 49. When contacts 44, 45 are br:idged by contact 43 on the rising of the diverter to enable solenoid 27 to be energized, opening main valve 19. As the breaker arm 51 moves to closed position, the arm 65 is moved away from contacts 71, thus de-energizing divertervalve coil 35, the valve returning to the lower position, opening contacts 44, 45 to cause the main valve to close. Valves 19, 30 may be operated manually by actuating the cores which project from the casing of the valve assembly. The overload relay 57, when energized sufficiently, closes contacts 59, energizing the solenoid 27 of the main valve to open the breaker. If the line 54 is in overload condition when the breaker is being closed, contacts 58 are opened and 59 closed. The diverter coil is de-energized and the valve falls. Since the main valve is still open the breaker is at once opened. In a modification, the main valve is biased open and the operating coil 27 is normally energized to keep it closed. Contacts 44, 45, 59, 62 and 70 are correspondingly re-sited. In this modification a failure on the supply lines 55, 56, will cause the breaker to open.
