Title: Electric furnaces
Inventor: WALKER ALAN JOHN
IPC: H05B3/64
Filed: 1962-12-08
Abstract: 1,004,708. Electric resistance furnaces. SPEMBLY Ltd. Dec. 5, 1963 [Dec. 8, 1962], No. 46421/62. Heading H5H. In an electric furnace generally similar to that of Specification 908,667 the current supply connection to the heating element 17 comprises axially-extended arcuate supporting legs 18 integral with the element 17 and having lower portions which engage copper current feeders 9 in the form of quadrants cut longitudinally from a hollow cylinder. The feeders 9 are secured in position and connected to the current supply by insulated pins 10 and are in contact with a water-cooled shell 1 through an insulating layer 13, contact between members 1, 9 and 18 being obtained by means of a conical ceramic plug 25 which is forced into engagement with the legs 18 by movement of a lifting plate 22 controlled by adjustment of a spindle 21. Insertion of a key to perform this operation is facilitated by a hole 29 in the plug 25 which hole receives the refractory pillar 60 supporting the furnace hearth. The plug 25 has parts cut away axially to leave diametrically-opposed conical quadrants alternating with diametricallyopposed plane surfaces. Axial movement of the element 17 is prevented by complementary circumferential projections and recesses 19, 20 on members 9, 19 forming a bayonet-type joint. Apertures 7 enable the furnace to be evacuated or supplied with an inert gas. Fig. 3 shows a modification in which the mating surfaces of members 9, 18 are conical, and a refractory distance-piece 37 is inserted between near semicircular portions of the legs 18 to prevent inward radial movement thereof when a nut 34 is screwed down on to an insulating ring 35 to engage members 9, 18. The member 37 has a counterbored hole to support the refractory furnace pillar, Fig. 4 (not shown). The baseplate 3 is provided with apertures fitted with plugged bosses 38 of the same size as the bosses 11 in the shell 1, so that if desired an alternative form of heating element, mounting therefor and current supply thereto may be employed, the bosses 38 being used instead of the bosses 11 which are then plugged and sealed in a manner similar to that shown for the bosses 38 in Fig. 1. One such alternative is described having a cylindrical-shaped heating element which is formed from tungsten and tantalum strips and is suspended from tantalum arms secured to water-cooled current-feeding tubes supported in the bosses 38, Fig. 5 (not shown).

Patent GB-471644-A (GB)
Abstract: 471,644. Testing coins. HARPER, P. S. Nov. 4, 1936, No. 30022. [Class 27] A combined annulus and weight testing device for coins comprises a pivoted counterbalanced coin carrier 1 adapted to receive a coin from a runway 7 in its uppermost position A, and to discharge the coin according to its weight either at an intermediate position B on to a reject runway 6, or at a lowermost position C to an associated coin-freed apparatus ; the carrier 1 being provided with fixed and pivotal annulus gauging fingers 11 and 12, the finger 12 engaging an adjustable stop 10 to check the carrier at the intermediate position B if the coin has more than a predetermined thickness just within the rim, so that such a coin also passes on to the reject runway 6 even if its weight is sufficient. In the construction shown, other characteristics of the coin are first tested by a mechanism constructed according to Specification 425,024. This mechanism has a pivoted clearing flap 9 covering a testing passageway, which flap is normally held open by a spring-actuated lever 16 pivoted at 21, a coin inserted through the entrance slot raising the lever 16 to permit the flap to drop into closing position until the lever 16 has returned to its initial position after a time interval determined by an escapement pendulum 27. In its initial position, the lever 16 also engages a counterweighted bell-crank 30 serving to set the carrier in one of its lower positions after each testing operation. If the carrier 1 stops in a position between A and B, or between Band C, a fork 36 on the bell-crank 30 engages about a pin 37 on the carrier, and moves it to position B to discharge the underweight coin on to the reject runway 6. If however, the carrier stops nearly at the position C, the pin 37 is in a position to be engaged by the outside edge of a leg of the fork 36, and the carrier is depressed into position C so that the coin is accepted as being sufficiently correct in weight. When a coin is inserted, the fork 36 releases the pin 37 so that the carrier 1 rises to position A ready to receive it. The stop 10 for the annulus gauge 12 is supported by the clearing flap 9 so that, when the flap opens at the end of each operation, the stop 10 is withdrawn to permit the annulus gauge points 11 and 12 to open to release a coin held thereby onto the reject runway 6. Specification 400,785 also is referred to.
