Abstract: 487,464. Welding. OSNABRUCKER KUPFERUND DRAHTWERK. July 23, 1937, No. 20435. Convention date, April 21. [Classes 83 (ii) and 83 (iv)] Making compound plates.-Metals and alloys are united by subjecting them to heat and to a pressure which is insufficient to effect any substantial deformation, but is sufficient to cause the surfaces to be united to lie in intimate contact, the operation being carried out in a reducing or inert atmosphere. A number of elements may be stacked in layers. Long bands or strips may be trated in sections. Loss of heat from the press is preferably prevented by layers of ceramic material. The plated products may be further worked by plastic deformation.

Title: Luminescent image storage elements and the use thereof
IPC: H05B33/00
Filed: 1957-06-28
Abstract: 865,969. Electroluminescent materials and uses. DU PONT DE NEMOURS & CO., E. I. June 28, 1957 [July 3, 1956], No. 20530/57. Class 39(1). Zinc sulphide or zinc-cadmium sulphide (up to 7% mol cadmium) activated within the critical range of 0.2-2.0% by weight of manganese is stated to have the property that luminescent energy stored in it by excitation radiation can be subsequently released as visible light by the application of an electric field; and this property is unaffected even by intense infra-red ambient illumination. The: property is used in a storage element, such as a tape, for the storage of information by means of the excitation radiation and its release by application of the electric field. An electric field of not more than 50,000 V/cm. may also be applied during excitation and the releasing field must then be greater than this (up to 150,000 V/cm.). Several applications of the same releasing field, which may be direct or alternating up to 500 kc./s., give succesive images of gradually diminishing intensity, or of the same intensity with successively increasing fields; the first may be used for monitoring purpose and the subsequent ones for actual recording. The excitation radiation may be electromagnetic radiation of wavelength below 5000Š, i.e. visible blue light, ultra-violet, X-rays and y-rays, and also α- and #-particles; but not electric fields or infrared. A filter dye against blue or ultra-violet radiation may be incorporated in the phosphor or in separate layers on each side of the phosphor layer. The time interval between the ending of excitation and the application of the releasing field may be as low as 15 secs. or as much as 20 hours. The phosphor is prepared by heating with a flux, such as an alkaline or alkaline-earth chloride or bromide or magnesium sulphate, to 550‹C. for 30 mins. A binder may be used, preferably a chlorosulphonated addition polymer of a mono- or di-olefin containing 2-5 carbon atoms per molecule, but many others are mentioned. The support may be any suitable film-forming material, many being mentioned but polyethylene terephthalate sheet being preferred; or paper, glass, metal, fabric. An X-ray sensitive element may have the phosphor on a metal support through which the rays act. A highly-reflective titanium dioxide layer may be used to exclude undesired radiation. Filter dyes may be Tartrazine, Auramine O, and many others. Fifteen detailed examples are given.

Title: Secrecy Communication System
IPC: H04L9/22
Filed: 1962-05-29
Abstract: 1,172,971. Secret telegraphy. NETHERLANDS, APPLIED SCIENTIFIC RESEARCH FOR STATE DEFENCE. 29 May, 1962 [31 May, 1961], No. 20697/62. Heading H4P. [Also in Division G4] A secrecy communication system operating with binary coding in which a plain message is enciphered by an interference pattern of finite length, which is determined by a number of subpatterns all of which have different numbers of elements, each sub-pattern being produced by an electronic circuit, is characterized in that for each of the sub-patterns means are provided to put the sub-pattern in a predetermined (zero) position at the occurrence of a certain determined group of elements in the enciphered message. The interference pattern may be generated by three electronic counters which count cylically in binary form up to 8, 11 and 13 respectively. Fig. 2 shows the counter which counts up to 8 and which comprises three triggers 1-3 operated through gates 12, 13 by clock pulses on line 11. The outputs XX<SP>1</SP>, YY<SP>1</SP>, ZZ<SP>1</SP> of the triggers are connected as shown to the eight AND gates 5 which therefore produce outputs sequentially. The gates 5 are each connected to one side of a switch 6, the other side of which is connected through OR gate 7 to the output F 8  and the inverting circuit 8 which produces the inverted output F<SP>1</SP> 8 . The switches 6 are set to produce a desired sequence of ones and zeros in the sub-pattern. The other two counters are similar except that they contain four triggers with provision for re-setting to zero after reaching ten and twelve respectively. Their direct and inverted outputs F 11 , F1 11 , F 13 , F<SP>1</SP> 13  with F 8  and F<SP>1</SP> 8  are taken to four AND gates, each of which has three inputs, the outputs of which are fed to an OR gate, Fig. 5 (not shown). This effects addition without carry of the three numbers F 8 , F 11  and F 13  to produce the final output F. Provision is made for re-setting the counters to zero on receipt of predetermined cypher signals. Using a seven digit code, namely start and stop pulses and five code pulses which are fed into a seven-stage register, it may be arranged that the counters are re-set when a start pulse is in the first stage of the register and when the second to the fifth code pulses have predetermined values. Signals representative of the start pulse and the second and third code pulses are fed to a three input AND gate which produces an output a when they have the predetermined values. The direct and inverted values d, d<SP>1</SP>, e, e<SP>1</SP> of the fourth and fifth code pulses are used together with a to re-set the counters to zero; thus in Fig. 2 the signals a, d<SP>1</SP> and e<SP>1</SP> operate a three-input AND gate 14 and re-set the counter to zero, whereas for the other two counters the combinations a, d<SP>1</SP>, e and a, d, e<SP>1</SP> are used. This gives a re-setting probability of <SP>1</SP>/ 16  for each counter so that if for any reason the counters at the transmitter and receiver are, out of step they will soon be restored to synchronism.

Abstract: 1468177 Pipe insulation MORGAN REFRACTORIES Ltd 30 April 1974 [3 May 1973] 21104/73 Heading F2P [Also in Division F4] A horizontal metal skid rail 1, 2 of a re-heat furnace is sheathed by C-shaped refractory blocks 4 and 5. The rail consists of a steel pipe 1 (e.g. water cooled) and steel rib 2. Each block is such that it hangs on an upper part of the pipe and swings under gravity beneath the pipe so as to extend more than half way thereunder into engagement with an opposite complementary block to form a collar therewith. Opposite blocks have circumferentially projecting terminal portions 6, 7 which interengage. Each terminal portion has a radially inner part of reduced axial dimension set inwardly from each axial end face of the block. These parts provide abutments which oppose axial separation of each pair of blocks forming a collar. As shown in Figs. 1 and 2, the radially inner part of block 5 provides a wedge shaped portion bounded by a plane surface 5F and a part frusto-conical surface 7C. This wedge shaped portion interfits an undercut recess 4D in block 4. Blocks 4 and 5 are identical and a similar wedge shaped portion of block 4, bounded by plane surface 4F and a part frustoconical surface 6C, interfits an undercut recess 5D in block 5. Between the blocks and pipe in space 3, Fig. 1, there is ceramic fibre (not shown). At the top, gaps 8 are packed with mortar (not shown). Fig. 3 (not shown) illustrates blocks with tongue and groove abutments (9C, 10D and 10C, 9D). These blocks are shaped to surround a tube of triangular cross-section.
