Patent GB-1275001-A (GB)
Title: Programmable electronic calculator
IPC: G06F15/02
Filed: 1970-03-11
Abstract: 1275001 Calculating machines SINGER CO 11 March 1970 [27 March 1969] 11615/70 Heading G4A A programmable desk-top calculator has a keyboard from which numeric data and instruction characters are inserted in a recirculating store. The store, e.g. an acoustic delay line, consists of a number of registers, each comprising a number of compartments, and each compartment permitting storage of equiweighted pulses to represent one numeric data item or one instruction character. Like order compartments of the registers are accessed consecutively followed by accessing of the compartments in the next higher order. One compartment (C3, R1, Fig. 3, not shown) is reserved for the entry of numeric data. Another, (C16, Rs) is reserved for entry of instruction characters, and another (C25, R4) for recall of instruction characters. Certain compartments (C16-C25 in Rs, R3 and R4) are reserved for instruction characters only. The numeric data is arranged on a last in first out basis, and the instruction characters on a first in first out basis. The pulses are shifted from one compartment or register to another by feeding the output of the delay line to a counter (43, Fig. 6, not shown), the count attained being transferred either to a second counter (44), which is counted down to zero to inject pulses in to the delay line, or to a third counter (45) which stores the count on the first counter and at a required instant thereafter transfers its count to the  second counter. The functions of +, -, x , ¸ are performed by suitable addition or subtraction in the first counter of pulses read from successive compartments. In the LEARN mode the numeric data and instruction words keyed in when a calculation is to be performed are entered via the relevant compartments, the compartment contents being shifted as necessary to allow entry of further information. When a Print key is operated the answer is printed or displayed on a c.r.t. When the same calculation form has to be performed, using different numeric data, a PROGRAMME RESET key is operated, causing the stored instruction characters to be shifted until the first to be stored is in the recall compartment (C25, R4). The new numeric data is now keyed in and an AUTO key operated after each set of numeric data so causing the corresponding instruction word to be recalled and the appropriate function performed. The stored programme contains Stop codes at each point where recall of instruction characters during AUTO has to cease for entry of further numeric data. When a Stop code is sensed numeric data unrelated to theprogramme may be entered and functions performed on it by operation of the appropriate function keys, these operations in no way disturbing the stored programme. Recall of the programme is started again when the AUTO key is pressed subsequently.

Abstract: 1,076,433. Safety arrangements for electrically heated blankets. INDOHEEM N.V. March 16, 1966 [March 16, 1965], No. 11621/66. Heading H2H. A safety device for an electrically heated blanket comprises a heating element 6 for the blanket which is supplied from an A.C. source 1, 2 by way of the normally open contacts 3, 4 of a relay 10 and a diode 5, the arrangement being such that current passes through the heating element during the half cycle when the supply terminal 1 is positive with respect to terminal 2. During the other half cycle the full supply voltage appears across the diode 5 and this voltage is rectified by a diode 7 to charge a capacitor 8 so as to energize the winding of the relay 10 thereby to maintain closed the contacts 3, 4 which are initially closed manually. Thus a fault such as an open circuit in the heating element circuit, a breakdown of the diode 5 or a short circuit between the element 6 and a protective conductive sheath 13 therearound will interrupt the charging of the capacitor 8 and hence de-energize the winding of the relay 10. A bi-metal switching device 11, 12 may be used to provide automatic control of the blanket temperature.

Abstract: 233,703. F÷ttinger, H. May 6, 1924, [Convention date]. Void [Published under Sect. 91 of the Act]. Sails. - Eddies in the flow of air or liquids around solid bodies are prevented by imparting additional flow energy to the friction border layer at one or more points. Thus, Fig. 2, a fan or the like may blow air through pipes 12, 13 to nozzles 10, 11 terminating in slots 7, 8 in a cylindrical body, so that the border layer flowing past these slots is supplied with additional energy which facilitates its advance into the zones 7-4, 8-4 of strongly increasing pressure. End discs 15 may be provided. Several slots 20, 21, 22, Fig. 4, may be provided one behind the other, and supplied with graduated amounts of energy, the energy required for the slot 20 being less than that for slots 21 or 22. The energy sources may be separate fan-wheels or a single fan-wheel tapped at different radii. Fig. 4 shows the method applied to the blades of turbines, wind wheels, fans, and the like, and to rigid sails. In a modification, Fig. 5, rotating vane-wheels 25, 26 are arranged in slots in the body so as to project into the border layer flowing past and supply it with additional energy. A series of such vanewheels may be arranged one behind the others The point of supply of the additional energy may be adjusted, for example by making it movable together with a portion of the wall, or certain slots may be put in or out of action. The fan, jet-pump, or the like supplying the energy may be driven by an independent motor, or the flow itself may be utilized for this purpose in combination with fan-wheels, suction nozzles, jet apparatus, or the like.

Abstract: 946,102. Moulding thermoplastic articles. PHILIPS ELECTRICAL INDUSTRIES Ltd. April 6, 1960 [April 9, 1959], No. 12222/60. Heading B5A. Articles, e.g. gramophone records, are moulded from thermoplastic synthetic material, e.g. vinyl acetate-vinyl chloride copolymer, by first forming the material in the shape of a disc of smaller surface area but greater thickness than the finished product, which disc is then heated outside a press mould to a temperature such that the modulus of elasticity is substantially zero and the viscosity so low that there is no substantial rise in pressure during the commencement of the moulding process, the disc introduced into the press mould which has been pre-heated and is subsequently placed in a press between two pressing blocks which are continuously cooled, and finally the press closed and maintained thus until the material and the press mould reach a temperature approximately equal to that of the cooled pressing blocks. As shown in Fig. 3, resilient elements 3 are provided between the pressing blocks 1, 2, cooled to 20‹ C. and the press moulds 4, 5 between which the moulding material 6 is located. The cavities 7, 8 are such that, when the pressure has been built up completely, the moulds 4, 5 wholly engage the pressing blocks 1, 2. In one example, the material is preheated to 165‹ C. and the mould to 145‹ C. When the mould and material are placed between the cooled pressing blocks, the temperature of the material slowly decreases and after one second reaches 155‹ C., by which time the mould temperature has also decreased to a somewhat lower value. However, during the first half second, pressure is not built up in the material owing to the high temperature and the use of the above-mentioned resilient elements. After this half second the material fills the mould completely, and the latter is also closed. The mould and material temperatures now rapidly decrease to the cooling temperature of 20‹ C. During the second half second, after the beginning of the moulding process however, the temperature of the material is still sufficiently high for full stress relaxation to occur. In two other examples, the material is pre-heated to 145 ‹ C. and the mould to 190 ‹ and 210‹ C. respectively.
