Filed: 1922-12-19
Abstract: 206,466. O'Donovan, D. S. Nov. 3, 1922, [Convention date]. Void [Published under Sect. 91 of the Act]. Metal-heating furnaces; muffle furnaces.-A furnace for heating rock drills &c. comprises a. series of open-ended muffles, in which the drills are heated in succession to gradually increasing temperatures. The series of muffles may be replaced by a single long muffle along which the drills are moved from a low to a high temperature portion. In the construction shown, short muffles 10 adapted to enclose the ends of the drills are arranged in two rows in a flue 5 which tapers in the direction of flow of the heating gases, and immediately above the fire-place 3 is a pair of muffles 10<a> for the final heating of the drills. Muffles.-The muffles may be single- or doubleended, and each is fitted in a, socket 13, Fig. V, and secured by a packing 15 of asbestos and a gland 16. Vertical muffles 20 for preheating the drills may be arranged in the outlet flue 7. Charging and discharging.-The apparatus for moving the drills into and out of the muffles consists of a carriage 21 mounted on rails 22 so that it can be moved to and from the furnace by the hand lever 23, toothed quadrant 26, and pinion 27 on the wheel axle. On the carriage is mounted a chain conveyer 30 having supports 31 for the outer ends of the drills. In operation the carriage is first retracted to withdraw the drill from the muffles, the conveyer is moved forward one step by a ratchet and pawl gear, and the carriage is then returned.

A switching circuit comprises a first transistor 4 with a driver 5 for switching it on and off and a second transistor 6 of opposite conductivity type the arrangement being such that when the first transistor 4 is on, the base electrodes and one of the other two electrodes of both transistors are at the same potential. Voltage sensitive means 8 are provided to be responsive to the potential at the one electrode of transistor 6 to cause the driver 5 to switch off transistor 4 when the potential at the one electrode exceeds a predetermined value. When transistor 4 is conducting, transistor 6 is out off, and current is supplied to load 1. An excess voltage across the emitter-collector path of transistor 4 is sensed by the means 8 which produces an output to switch transistor 4 off and transistor 6 on, thus reducing the input to the sensing means 8. Means may also be provided to operate a relay to disconnect the circuit from the supply if the potential at the emitter of transistor 6 falls below a specific value.

Abstract: 765,220. Ear-piercing appliances. PERVINKLER, P. L. March 16, 1955 [Dec. 16, 19531, No. 35041/53. Class 81(2) An ear-piercing device comprising a cylinder 11 containing an outer plunger 14 for pressing the ear lobe against one arm 34 of a U-shaped pressure plate 12 attached to the cylinder 11, and an inner plunger 21 for projection beyond the outer plunger 14 and the cylinder 11, is characterized by the provision, in the base 32 and arm 30 of the U-shaped plate nearest the cylinder 11, of a slot 31 wide enough to allow a large ornament 44 on a sleeper ring 37 to pass through and, in the other arm 34 of the U-shaped plate, a narrow slot 35 for the passage of a needle 36 and the sleeper ring 37.

The detector 5 and its diaphragm 13 can be moved as indicated by the dotted lines to receive particles of different energies, depending upon the thickness or density of the sheet to be measured. The magnet is preferably arranged so that its field is at right angles to the plane of the particle's trajectory (the plane of Fig.1). In further embodiments Figs.3 and 4 (not shown) a further detector is used to either receive direct radiation or that reflected off diaphragm 12 or to receive radiation which has passed through the sheet but which has energy levels different from that being received by the other detector. In all cases the detectors are connected so that the difference in the outputs is fed via an amplifier 7 to a recording instrument 8.

Abstract: 800,574. Semi-conductor devices. PHILIPS ELECTRICAL INDUSTRIES, Ltd. Dec. 9, 1954 [Dec. 12, 1953], No. 35678/54. Class 37. In a semi-conductor device comprising a semi-conductive member, which has a rectifying contact formed in or on it and is housed in a gas-tight envelope through the walls of which electric conductors extend and are sealed, the space in the envelope is divided into at least two parts. One of these parts is adjacent a seal of the conductors and is evacuated or occupied by a material with higher specific resistance to heat flow than the material occupying the second part which completely encloses the semi-conductor member. The transistor of Fig. 1 comprises a semiconductor body with alloyed electrodes, immersed in a viscous heat conducting medium 5, e.g. polymethyl siloxane, in glass tube 1. The lid through which connecting conductors 3 are sealed is fused to the tube by heating, while the tube is held by cooling clamps 6. A heat-conducting powder, e.g. quartz or copper or aluminium may be used instead of a viscous filler the space above it being filled with heat insulating material, e.g. aluminium oxide or asbestos. Where copper or aluminium is used the semi-conductor body and parts of the conductors passing through it are given a coating of insulation. Instead of a glass tube a metal tube may be used with a glass cover through which the conductors are sealed, sealed to it, e.g. by use of a low-melting enamel. In the Fig. 3 and Fig. 4 (not shown), arrangement comprising a single and double diode respectively the semi-conductor bodies 12 and conductors 3 are inserted through the narrowed end of a tube, a viscous filler is introduced around the bodies by syringe and then the ends are sealed to the conductors. The bodies may in addition be embedded in a hardening filler, e.g. polystyrene, polyisobutylene or that sold under the Registered Trade Mark " Araldite," before insertion in the tube.

Abstract: 1,146,632. Sheet forming. OLIN MATHIESON CHEMICAL CORP. 10 Aug., 1966 [24 Aug., 1965], No. 35778/66. Heading B5A. [Also in Divisions B3, E1 and F4] A method of forming an expanded passageway in a metal or plastics panel comprises reducing the thickness of the panel on each side of the passageway further to expand the walls of the passageway and inserting into the passageway a tool to form the passageway into a desired configuration. The panel is initially formed by rolling together two metal sheets, which may be of different alloys, having a pattern of stopweld between their mating faces. The passageway 7 is opened by fluid inflation and the expansion on one side is greater than that on the other. A portion of the passageway is then further expanded placing the panel in a press so as to produce areas 20, 21 of reduced thickness. The excess material flows into the walls of the passageway and the final shape is obtained by the insertion of a tool (12), Fig. 6 (not shown).
