Abstract: 503,076. Uniting metal to ceramic material by heat; electric discharge apparatus. TELEFUNKEN GES. FUR DRAHTLOSE TELEGRAPHIE. Aug. 27, 1937, No. 23516. Convention date, Aug. 27, 1936. [Class 36] [Also in Groups XXII and XL] In a method of exhausting and sealing an electric discharge vessel the main portion of the envelope of which is composed of metal but which also comprises a portion of insulating material, the envelope, or the portions composing it, are arranged within a vacuum furnace and subjected to degassing by heating, the furnace next being exhausted of air, a temporary gap between the metal and insulating portions, or apertures in one of them being provided for the purpose of exhaustion and the introduction of a filling gas if desired, after which the gap or apertures are sealed by means of a fusible medium while within the vacuum furnace and whilst subjected to a vacuum or to the desired gas pressure. If the exhausting apertures are provided in the metal part of the vessel they may be sealed, as shown in Fig. 3, by disposing pieces of solder 25 adjacent to apertures 24 in the metal part 22, so that when the latter is heated, e.g. by induced high-frequency currents, the solder fills the apertures. The metal parts 22, 23 consist of discs which are soldered to a ceramic ring 21. Alternatively; if the apertures are in an insulating part, which may consist of a ceramic disc, the fusible sealing medium may consist of solder or molten glass. Fig. 1 shows a discharge vessel comprising a metal anode 7 with a ceramic base 5 which is formed with an annular groove 6 to receive the bottom edge of the anode 7, these members being located within a vacuum furnace 1 connected to a pump by a pipe 2. The anode 7 is supported by a clamp 8 on a rod carried by a plate 10 which can be adjusted by wing-nuts 12 on bolts 11, the arrangement being such that a small gap is allowed between them during evacuation and degassing. The anode 7 is next lowered into the groove 6 of the base 5 and heated by induced currents until solder, arranged beforehand in the groove 6, is melted to form a seal between the members 5, 7. In a modification a metal anode with a slightly flared edge is inserted in an inverted position in a vacuum furnace and receives a ceramic closing- disc, an annular channel being left between the edges to receive a ring of solder which is melted after evacuation and degassing of the parts. Specifications 486,256 and 492,480 are referred to.

Title: Improvements in and relating to methods of and apparatus for moulding articles of cellular plastic material
Filed: 1949-09-19
Abstract: 664,318. Moulding cellular plastic material. BRITISH THOMSON-HOUSTON CO., Ltd. Sept. 19, 1949 [Sept. 30, 1948], No. 24043/49. Classes 70 and 87(ii) In the production of cellular moulded parts involving the expansion or foaming of plastic material, to overcome the disadvantage of the foam sticking to its container as it expands, apparatus comprises a receptacle 3 for a foam-producing mass 4, a form 5 enclosing the receptacle, the form and receptacle being movable relatively to each other upon expansion of the mass, and counterbalancing means 15 for controlling the relative movement of the form and receptacle. A perforated plate 9 rests above the receptacle 3 and has an opening 17 through which resinous mixture to form the mass 4 is formed when the apparatus is assembled. The perforations allow escape of gas and the expanding foam acts against the remaining surface of the plate to cause it to move the form upwards to the position shown in Fig. 2. To facilitate the removal of the form when the expanded mass has solidified it is made in two halves 6 7 of sheet metal clamped together at 8. Alternatively the form may be of paper. In a modification the form 5 and plate 9 are fixed and the receptacle 3 is movable, the latter being counterbalanced by weights. The density of the product may be controlled by adjusting the counter-balance. Petroleum is recommended as a lubricant between the moving parts and kraft paper as a lining for the form. The forms also may be of paper, but metal is preferred for the whole apparatus. Specification 598,642, [Group IV], is referred to.

Title: Improvements in and relating to the generation of electrical impulses corresponding to apertures in a punched card
IPC: H01H43/08
Filed: 1954-08-19
Abstract: 757,851. Photo-electric record sensing. MITHRA, AKT.-GES. Aug. 19, 1954 [June 23, 1954], No. 24173/54. Class 40 (3). A device for generating electrical impulses representative of information on a punched card comprises a rotatable hollow cylinder on the surface of which is clamped a conventional punched card 136 the cylinder being provided with apertures corresponding to the possible positions of holes on the card, a light source inside the cylinder and photo-electric converters outside so arranged that each receives light from one of the apertures arranged along a generator of the cylinder through a separate light passage. As shown, the cylinder 121 on which the card 136 is arranged has end-pieces 122, 123 which overlap the edges of the card and hold it in place. A pair of pins on the cylinder co-operate with special holes in the card to assist in locating the card. Endpieces 122 carry flanges which co-operate with similar flanges on a driving member 110 to enable the cylinder to be coupled to or withdrawn from the member. The cylinder is positioned so that its flanges enter the spaces between those on member 110 and is then rotated so that its flanges engage behind those on the member. Member 110 is attached to a ring 107 which rotates on ball and roller bearings 105, 106 on a central hub 104. The outside of the ring 107 carries teeth 108 which enable both the ring and, through the coupling, cylinder 121 to be rotated. Spring-loaded balls 130 mounted in ring 107 press against the flanges of cylinder 121 maintaining those flanges in engagement with those on driving ring 110. The internal surface of cylinder 121 has longitudinal slots; the outside surface circumferential. These slots are of such depth that they intersect forming apertures corresponding to those on the card. Fixed central hub 104 on which bearings 105, 106 are mounted carries fixed cylinder 113 having a single slot 119 along its generator. Inside the fixed cylinder are lamps 114. Alternatively, a single tubular lamp may be used. Connections to the lamps are brought through the central hollow hub as also is a supply of cooling air for the lamps. Reflectors 118 are mounted one at each side of the row of lamps. Above the surface of the rotating cylinder is a block 146 consisting of a number of sections 147 bolted together. Above the sections is block 148 of resilient material for example sponge rubber in which are mounted in suitable recesses twelve photo-electric cells in three rows of four each (Fig. 2). Each cell is associated with an aperture 150 in block 148 so as to receive light from one of the twelve possible positions along a generator of cylinder 121. Thus as the cylinder rotates all possible positions for apertures in the card are examined.
