Title: Improvements in or relating to the production of hollow moulded articles from thermoplastic material
IPC: B29C49/04
Filed: 1952-12-24
Abstract: 713,419. Glass. LACRINOID PRODUCTS, Ltd., and HAGEN, R. Dec. 24, 1952, No. 32715/52. Class 56 [Also in Group V] The leading end of an extruded tube 2 Fig. 1, of a length greater than that of the article to be produced, is passed over a compressed air nozzle 3, and a severed length of the tube is enclosed between the sections 4, 5 of a mould, the leading end of the tube being pinched by the mould into sealing contact with the nozzle and the other end of the tube being sealed between the mould sections. Then air is blown into the tube to conform it to the shape of the mould (Fig. 2). In Figs. 1 and 2 the extruded tube is of smaller cross-section than the mould, but it may be of larger cross-section, as in Fig. 4, in which case excess material 20, Fig. 5, is squeezed out at the sides. As shown, a bottle having an open neck is formed, but for. making other articles the open-ended portion may be sealed or cut off: other articles mentioned are balls, dolls, ampoules and fountain-pen bodies, and the tubes described in Specification 709,370. The processes illustrated are for batch procedure, but continuous production may be achieved by (a) continuously extruding a tube to a succession of sectional moulds which move past cutting and blowing stations, each mould incorporating a reciprocating air nozzle which at the stages required is brought into communication with a scource of pressure air; or (b) feeding at spaced intervals a succession of batches of material to an extruder which delivers an extruded tube between the sections of a mould, the subsequent operations of blowing and ejection being effected without moving the mould relatively to the extruder, and a single air nozzle being arranged to reciprocate from a position in which it registers with the extruded tube to a position in which it assists in discharging the formed shape.
Patent GB-1563444-A (GB)
Title: Monitoring and alarm apparatus
IPC: E05G1/10
Filed: 1977-08-04
Abstract: The device serves in particular for monitoring strongrooms and is actuated if a break-in attempt is made by means of drilling, explosives or welding, for example with laser beams. It has an acoustic-electrical transducer (1) in which a temperature sensor (31) is arranged. A first signal path (A) which is connected to the transducer consists of an amplifier (2), a threshold value detector (4), an integrator element (6) and an output stage (8 to 11) for generating the alarm signal and reacts to small signals which last for a relatively long period of time. A second signal path (B) which is also connected to the transducer and is of similar design to the first signal path reacts to large-amplitude signals which occur briefly and are due to an explosion caused by explosives. The temperature sensor is connected to the output stage (9) and generates an alarm signal when a threshold temperature is reached by the transducer, if for example welding takes place on the strongroom using laser beams which do not generate any solid-borne vibrations but only heat. <IMAGE>

As shown in Fig. 4 an aperture card 61 bearing a chip of micro-film 62 is located in a film gate defined by members 52, 54 having respective spring biased glass plate 56, 58. The film gate is supported by a member 110 which is attached to member 102. Members 102, 104 together define the carriage and are spaced about member 82. Fig. 5 shows a scissors linkage 172 which permits the carriage to slide along rail 184 and raise/lower the film gate. The filter 42 may comprise two section of different densities. The control lever 24 includes a rod 140 with a ball end 144 engaging a well 146 formed on the member 104. The lever 24 pivots about a ball and socket joint (only socket 152 shown) so that the ball 144/well 146 connection can move the carriage and hence the picture gate. Rotation of the lever 24 causes the socket 152 to rotate and thereby rotate a gear segment 132 mounted thereon. The gear 132 in turn rotates gear 130, shaft 128 and pulley 126. As shown in Fig. 5 the filter 42 is moved by tensioned cord 118 passing over pulleys 120, 122, 124, 126. To insert/ remove an aperture card from the gate the lever 24 is depressed (i.e. into the plane of the drawing of Fig. 5), this lifts the members 52, 54 and by virtue of a follower (164), Fig 7 (not shown) on member 52 engaging a cam (164) on plate 70 the members 52, 54 are separated. This opening of the gate causes the projection lamp 34 to be extinguished. FOCUSING of the projection lens 46 is by rotation of control knob 32 which moves leaf spring 90 so that rod 68 supporting the lens 46 is moved against the bias of spring 84.

Abstract: 806,836. Digital electric calculating-apparatus. INTERNATIONAL BUSINESS MACHINES CORPORATION. Nov. 17, 1955 [Nov. 18, 1954], No. 32937/55. Class 106 (1). An electrical circuit for receiving data in the form of bit-representing input pulses and delivering an output representing the remainder produced by dividing said data by a predetermined modulus (four), comprises at least two counting circuits operable independently to count bits of said data, including switching means for intermittently connecting a denomination of one of said counting circuits to the other counting circuit, so that the count of said other counting circuit is modified in accordance with the value registered in said denomination. The data comprises a succession of binary numbers appearing in parallelform on leads 43 and 44, Fig. 1a, the pulses representing each number being initiated by the depression of one of a set of nine keys and representing the number of one-bits in the binary coded form of the key-value, and has its units denomination pulses passed on lead 43 via an inverter 12, Fig. 1b to a first counter comprising cascade connected triggers 15 and 16, and its twos denomination pulses passed on lead 44 via an inverter 13 to a second counter comprising a trigger 17. Thus on each key depression pulses representing the number of one-bits in the binary coded form of the key value are entered into the counters where they are accumulated independently modulo 4. At the end of the succession of numbers a relay R1, Fig. 1b is energized, coupling the twos denomination, trigger 16, of the first counter with the second counter via a cathode follower 14 and a coincident gate 18, resulting in the application of a further pulse to the second counter, trigger 17, if trigger 16 is " on " (left-hand side conducting). The final result is that the potentials of leads 49 and 48 represent in the binary scale the required remainder which can be entered into a receiver 11 (for example a printer), to which the key values are transmitted, for checking purposes. In practice, the number source, shown as keys in Fig. 1a, would probably be direct from a computer. Zeroizing of the counters is achieved by energizing a relay R3, Fig. 1b Specification 806,354, [Group XXXVIII], is referred to.
