Title: Method and apparatus for the manufacture of flexible sheets of heat cured plastic material
Filed: 1958-07-31
Abstract: 838,807. Moulding sheet material of foam rubber or other heat cured plastic substance. MOORE, J. F. July 31, 1958 [Aug. 8, 1957], No. 24625/58. Class 87(2). A flexible sheet of foam rubber or other heatcured plastic material is continuously formed by depositing uncured material on the upper.- most portion of a horizontal drum 10, e.g. by means of a reciprocating nozzle 33, and rotating the drum to pass the deposited material through a heating zone to gell it, the zone being provided by a high frequency electric field applied between an electrode 40 and the drum, and then through a bath 28 of hot liquid to cure the material. The thickness of the layer applied to the drum 10 is determined by an adjustable water-cooled doctor blade 37. The bath 28 may contain water heated by steam supplied through a pipe 59. The cured sheet is taken off the drum by a roller 50, the take-off zone of the drum being cooled by air supplied by jaws 45, and by cooling water supplied through tubes 47, 48. The drum 10 may be of aluminium provided with projections 22 of electrically insulating material. The high frequency electric field may be replaced by an infra red heating device.

Title: Improvements in or relating to alternating current rectifiers
IPC: H01J19/40
Filed: 1947-09-08
Abstract: 639,801. Thermionic power converters. CINEMA-TELEVISION, Ltd., and BUCHANAN, W. H. Sept. 8, 1947, No. 24699. [Class 39 (i)] In a hard vacuum alternating current rectifier adapted to operate at high voltages, and comprising a filamentary cathode 2, deleterious effects owing to liberation of occluded gases by bombardment of the glass or other insulating material of the evelope 1 or electrode supports by electrons drawn from the anode 3 by the positive potential of the cathode and leads connected thereto, during the inverse half-cycle, are minimized by providing a metallic electron intercepting member 5 of imperforate form, electrically connected to the cathode, and surrounded only partly by the anode. This member, which may support the cathode, can be heated to a higher temperature during manufacture, and has a smaller surface area than the envelope 1, and will thus contain a smaller quantity of occluded gas. The diameter of the member within the anode may be, for example, one quarter of the anode diameter, but widens outside the anode to provide a cylinder of sufficient size to collect electrons following a path such as that illustrated by the dotted line A.

[Class 97 (i)] A refractometer of the critical angle type comprises a small refracting prism of high refractive index, a lens close to the exit face of the prism, an optical viewing system comprising one or more lenses and a mirror or reflecting prism, and a scale of which an image is formed in the eyepiece. As shown, the apparatus comprises a casing 1 having a window 3 admitting light to the small prism 10, the optically flat face 11 of which projects through a slot in a wall 7 of the casing. Light internally reflected by the face 11 emerges from the optically flat face 12 and is received by a lens 15 having a plane surface 16 adjacent the prism, and a curved surface 17. The viewing system comprises an eyepiece 6, a lens 20 and a mirror 22. A scale plate 24 is mounted below the mirror and is seen along one side thereof, which is left unsilvered. Alternatively, the whole of the mirror may be thinly silvered so as to transmit light from the scale. The substance 35 of which the refractive index is to be measured is placed in contact with the face 11 of the prism 10.

Title: Improvements in or relating to the manufacture of semiconductor valves

Filed: 1961-07-12
Abstract: 983,074. Semi-conductor devices. GENERAL ELECTRIC CO. Ltd. July 4, 1962 [July 12, 1961], No. 25321/61. Heading H1K. A method of manufacturing a semi-conductor device consists in placing a germanium wafer with substantially the whole of one of its main faces in contact with a metallic support and in heating the assembly in such a manner that heat is conducted to the wafer via the support thus establishing a thermal gradient across the wafer and causing the hottest part only of the wafer to form a molten alloy with part of the support at a temperature lower than the melting point of either the germanium or the basic material of the support, the assembly then being cooled to bond the wafer to the support, the physical characteristics of the unalloyed part of the wafer remaining substantially unchanged during the loading cycle. Preferably, the non-bonded face of the wafer is maintained in contact with a heat sink during the process. The invention is suitable for masking devices such as diodes and transistors; in the embodiment described a high frequency point contact diode is produced. To form the diode a wafer 1 is placed on a support 2 of iron/nickel/cobalt alloy which is held in the well of a stainless steel body 6 itself held in a carbon block 3 through which heating current is passed. This assembly is within a nitrogenfilled glass bell jar 11 in the top of which is a hole through which nitrogen escapes around a stainless steel plunger 9 resting under its own weight on the wafer and acting as a heat sink. The progress of alloying is under the control of an operator observing the process through a microscope (not shown). To complete the diode, Fig. 2 (not shown), the support carrying the wafer is mounted in a brass bush scaled to one end of a quartz tube and a generally similar support bearing a metal whisker which contacts the wafer is mounted in a second brass bush sealed to the other end of the tube. In a variant the wafer support is copper plated and that part of the copper plating in contact with the wafer forms an alloy with the germanium and some of the support material.

The control pump 8 has a suction inlet in common with the pump 6 and an outlet chamber 14 leading through pipe to a hand control valve (not shown). If this valve is closed a spring- loaded valve 15 is moved to the left and the control pump delivery passes along passage 22 to the hoisting pump delivery port 9a, past which liquid is circulated idly by the main pump when the hoist is not working. The valve 15 has a piston 16 working in a chamber, the right-hand end 20 of which is connected to chamber 14 through a threaded resistance passage 75 formed between parts 17 and 18. When the pump 6 is driving the hoisting motor the pressure in port 9a rises and valve 15 is fully opened so that the pump 8 assists the pump 6 to drive the motor.
