Abstract: 897,936. Sterling-to-decimal converters. INTERNATIONAL BUSINESS MACHINES CORPORATION. Feb. 13, 1961 [Feb. 16, 1960], No. 5265/61. Class 106 (1). A relay tree, Fig. 3, is set by indications on a punched card of a sterling quantity to provide paths to output terminals 18 to 22 representing orders of a decimal fraction for groups of equal valued pulses indicating the value of the decimal fraction equivalent to the sterling quantity. A sterling punch is first sensed as the card moves row by row past a sense station 2 and operates a relay 7 to close contacts 7.1, 7.2 and 7.3. Detection of a tens of shillings punch operates relay 9 to switch contacts 9.1, adding five to the number of pulses which would otherwise reach terminal 18. Counter magnet 14 controls the movement of a brush 25, one pulse through the cam contacts of Fig. 1 and contacts 12.1 stepping the brush one position. Contacts 12.1 are closed if a units shilling punch is sensed. The number of pulses to magnet 14 is the number of even valued card rows which pass the sensing station while and after the punch is sensed. A correction is made for odd values by operating relay 11 to switch contacts 11.1 if the punch is sensed while an odd row is passing the sense station. This adds five to the number of pulses which would otherwise appear at terminal 19. A punch in the pence column energizes that relay against which is the moving brush of a " digit filter " 15 and closes contacts from the sets d 0  to d 11  at terminals 19 to 22.

Abstract: 521,889. Injection moulding. ERNST, W., and LAWYER, I. B. Sept. 26, 1938, No. 5427/40. Divided out of 521,840. [Class 87 (ii)] In a feeding device for a machine for moulding plastic materials by injection, the material is supplied in granulated form from a hopper 96 to. the injector chamber through an inclined passage 94, in which works a worm 99 driven through gearing by a motor 109. The charge is forced by the hydraulic ram 67 past the diverting member 74 and through the nozzle 76, the end 78, of which is formed to correspond with an inlet socket of one of the die parts. Fins 80 arranged within a lagged jacket 81 heated, for example, by hot oil, conduct heat to the pressure chambers and nozzle. The heated part is insulated by a disc 87 from a part cooled by a jacket 90, the cooling preventing premature softening of the material. A timing switch, arranged in the circuit of the motor 109, is so set that slightly more than a unit charge is injected into the injector chamber by each operation of the motor and screw 99, which overfeeding prevents a scarcity of material. The accumulation after several strokes prevents a complete working stroke of the ram. To remedy this, the ram is provided with a cam 66 which closes, in turn, switches 115, 116. When the ram fails to complete a working stroke, the switch 116 is not closed, so that, when the ram returns and closes the switch 115, the motor 109 fails to operate, the motor circuit being such that this result is obtained. The next stroke of the ram will use the excess material, and subsequent operation of the screw 99 will be normal until the next accumulation is to be removed. Specification 505,699 is referred to.
