Title: System of programmed working for space telecommunication station
IPC: H04B7/195
Filed: 1965-11-24
Abstract: 1,110,599. Space satellite communication system. A. PROFIT, and R. CHOLLET. 24 Nov., 1965 [25 Nov., 1964], No. 49949/65. Heading H4L. A system of programmed working for a space tele-communication station using a plurality of passing satellites, enabling continuous communications to be assured by successive use of a plurality of tracking aerials, is characterized in that the co-ordinates necessary for the acquisition of each of the satellites visible from the station, which co-ordinates are calculated at regular intervals and recorded chronologically to constitute a general co-ordinate programme, are distributed selectively to any one of the aerials according to a working programme which likewise produces for the switching over of modulation channels and which can be manually overridden. The co-ordinate and working programmes are each recorded chronologically in blocks, in duplicate on four tracks of two, five track, punched tapes, the fifth tracks being used for a parity check. The two copies of each pgrogramme are read simultaneously in real time by readers, capable of travelling forwards or backwards, and are subject to conformity checks and parity checks, which, on revealing an operational defect in one reader, puts the reader out of service, continuing the reading with the other reader, and operates an alarm, or, on revealing an error of unidentified origin in a block causes a limited number of re-readings of the block and sets off an urgent alarm if the error is repeated on each re-reading. Each co-ordinate programme is read block by block a sufficient time before the corresponding satellite occupies said read coordinates for the acquisition of the satellite by the aerial prescribed in the working programme. All signals and alarms are monitored or fed to a central control point, said central control point being provided with means whereby the allocation of a satellite to an aerial, the transmission of the acquisition data to the aerial and the switching over of the modulation channels can be effected manually, independent of the recorded programmes. A complex logic circuit embodiment of the invention is described in detail.

Title: Process for improving, especially for supplying permanent stiffening effects to, cellulose textile fabrics and textile fabrics when treated by such process
IPC: D06M13/278
Filed: 1964-12-14
Abstract: Textile fabrics consisting of or containing cellulose fibres are stiffened by treating them with at least one polymeric substance having at least one hydroxy and/or amine group per molecule and a reactive saturated organic compound which is the presence of an acid or basic catalyst is capable of reacting with the polymeric substance and, with the cellulose fibres of the fabric, and with a liquid comprising water and/or an organic solvent and the acid or basic catalyst at a temperature below 100 DEG C. until reaction has taken place between the polymeric substance and the reactive compound and between the cellulose fibres and the reactive compound.  The polymeric substance may be a carbohydrate or derivative thereof, e.g. starch or a starch derivative, polyvinyl alcohol the hydroxy groups of which may be partially substituted, a protein e.g. gelatin, a polyamide or a polyurethane, and the reactive compound may be an N-methylol compound, e.g. dimethyloldihydroxyethylene urea, or aldehyde containing 1-10 carbon atoms when a strong acid catalyst e.g. formic, sulphuric or hydrochloric acid is used, or a compound containing two oxiran rings or two halohydrin groups per molecule, epichlorhydrin or a di halopropanol when a strong base catalyst, e.g. sodium hydroxide is used.  The fabric may first be treated with the polymeric substance and reactive compound and if desired other additives, such as softeners and wetting agents, and subsequently directly or after an intermediate drying stage treated with the liquid mixture containing the catalyst. Alternatively only the polymeric substance is applied first and the liquid mixture containing the catalyst, reactive compound and any other additives subsequently applied if desired after intermediate drying.  The liquid containing the catalyst may be an aqueous solution or a mixture of a water-miscible organic solvent, e.g. ethanol, with water.  The fabric may be squeezed and, rolled up, wrapped in a polyethylene foil and held at a temperature below 100 DEG C until the reaction has taken place.  Woven or non-woven interlining fabrics made from cotton or mixtures of polyester fibres and cotton fibres or of polyamide fibres and regenerated cellulose fibres may be treated.

Abstract: 1,081,659. Verifying bank notes. AUTOMATIC CANTEEN COMPANY OF AMERICA. Dec. 15, 1964, No. 51109/64. Headings G4R and G4T. Apparatus for comparing one translucent object (e.g. a bank note) with another comprises a carriage adapted to move each object past a corresponding photo-electric sensing station so that each is scanned along a number of paths, the responses of the two sensing stations being compared to detect differences in the two objects. The apparatus is for dispensing goods in return for a bank note, the proffered bank note being compared with a standard, genuine bank note before being accepted. The standard bank note is carried in a recess 18, Fig. 1, in a sliding tray 12 and the customer places his bank note in recess 19. When button 39 is pressed motor 38 drives the tray so that the customer's bank note is carried under cover 31. During this movement both bank notes are illuminated by lamps 13, 14 and 15, 16 and a row 20 of photo-resistors senses the standard note, while a row 21 senses the customer's note. The resistances of the photoresistors change with changing amounts of transmitted light. Corresponding ones in the two rows are compared in a bridge circuit, Fig. 5b. Outputs are taken from variable potentiometers 101-111 connected between each pair of photo-resistors. The bridge is supplied by a centre-earthed transformer winding 112 and any difference in the resisance of a pair causes an output. These are combined in diodes 131-139 and applied to a transistor trigger circuit 120 which is set by a predetermined threshold signal to indicate that the proffered bank note does not compare with the standard. If the trigger 120 is not set the note is accepted and drawn into the machine by being forced through a central slot 44 in the tray, through a corresponding slot 45 in the housing and gripped by rollers which pass it to a bin. This is effected by a blade moving in guide 48 which moves downwardly under the control of solenoid 51 to fold the note through the slot. The trigger 120 is reset by the opening of a relay contact R2C at the beginning of this operation and is set again by signals from photo-resistor pairs 94, 94<SP>1</SP> and 95, 95<SP>1</SP> placed on either side of the slot. These give a setting signal when the bank note has been fully removed from the tray and direct light falls on photo-resistors 94<SP>1</SP> and 95<SP>1</SP>. The dispensing mechanism is now operated to deliver the good purchased at 11. To compensate for differences in the general light transmitting properties of the two bank notes, the amount of light transmitted by each is sensed and the lamp 13 is controlled to be more or less bright than lamp 15, and lamp 14 is similarly varied with respect to lamp 16.
