Filed: 1965-10-08
Abstract: 1,106,908. Making fibres from film. SOCIETE NORMANDE DE MATIERES PLASTIQUES. 8 Oct., 1965 [9 Oct., 1964], No. 42854/65. Heading B5B. Fibres are obtained by repeated cutting from an edge of a polymer film oriented in the direction of the edge. A large number of fibres are cut simultaneously by forming a block 1 of a number of films having the same orientation and planing all the edges simultaneously, the resulting fibres being removed by take-off mechanism 7, (Fig. 1) or by forming a reel 11 of the film on a mandrel and feeding the end of the reel against a rapidly revolving circular cutter 14 (Fig. 2). Alternatively the reel can be mounted in a lathe and a lathe tool fed against the reel. Polypropylene and polyethylene are the preferred polymers and the natural orientation of extruded film may be increased by drawing, e.g. two and a half times at 98‹C., before cutting into fibres. The film may be oriented transversely but to a lesser degree than longitudinally. The resulting fibres, which have dimensions dependent on film thickness and rate of feed in the cutting operation, may be shredded to obtain finer fibres. Staple fibres are obtained by notching the block in Fig. 1, before planing.

Filed: 1967-09-21
Abstract: 1,205,037. Cyclone separators. D.I.P.A. 21 Sept., 1967 [22 Sept., 1966], No. 43006/67. Heading B2P. A cyclone purifier, for separating impurities contained in a solid, granular or fibrous material suspended in a liquid, comprises a cylindrical chamber 1 having a helical feed tube 2 at its upper end and a vortex finder 12 projecting inwardly from its top 10 and having a length equal to ¢ to ¥ times that of the chamber 1, and a number of inverted frustoconical chambers 4, 6, 8 successively joined to the base of the chamber 1 and having successively decreasing apex angles α, # and y, the lowermost chamber 8 having an opening 9 for the discharge of separated impurities. The decreasing angles, which may be respectively 10, 8 and 6, have the effect of reducing the difference between the peripheral speed of the impurities and that of the axial stream of treated suspension travelling upwards towards the vortex finder so as to prevent entrainment of the light impurities by the axial stream. The apex end of the chamber 8 opens into a recovery device comprising a cylindrical chamber 13 and frusto-conical chambers 14, 15 also of successively decreasing apex angles. Water is tangentially injected under pressure into the chamber 13 through a tube 16 to re-establish the previously reduced peripheral speed and to increase the fluidity of the suspension so as to facilitate separation of any desired material entrained into the chamber 13 with the impurities. The latter are discharged at the bottom of chamber 15. The height of the chamber 1 is at least 2¢ times its diameter.

Title: Circuit Testing Apparatus
IPC: G01R31/28
Filed: 1967-09-25
Abstract: 1,198,134. Semi-conductor pulse circuits. INTERNATIONAL BUSINESS MACHINES CORP. 25 Sept., 1967 [10 Oct., 1966], No. 43468/67. Heading H3T. [Also in Divisions G1 and G3] A current summing circuit for use in providing standardized currents in a condition generator for a circuit test apparatus (see Division G1) makes use of individual 5CR controlled circuits 102 (Fig. 3) the SCRs being switched according to programme inputs from a central processor. An SCR e.g. 101-1 when switched in via input diodes drives a transistor 103-1 into saturation to provide a defined current in the precision output resistor 120-1. By switching in suitable combination of the circuits 102 any required total output current can be derived. The SCR's are reset by triggering the transistor 105. Relay 113 controlled by a further programmed SCR controls the output polarity. In a further arrangement for supplying standardized currents, a similar system is used but the transistors 103 are replaced by relays (Fig. 4, not shown). These currents are applied to driver-load circuits, e.g. 71 (Fig. 5b) where they are passed to an output line via a common base amplifier 216, whose base potential is controlled by Zener diode 220. The driver load circuit incorporates a double emitter follower 200, 201 which receives at its input 202 a programmed voltage, so that the output voltage at which the standardized currents are supplied may be controlled. The diode 203 enables fast transitions in drive level to be achieved. Diodes 206, 217 prevent reverse breakdown in the associated transistors. The ferrite cores 209, 224, 225 prevent ringing during fast transients. To avoid excessive power dissipation in the emitter follower transistors, at relatively high base-collector voltages, the supplies to the emitter followers are derived from circuits 80, 81 so as to be varied in accordance with the emitter follower inputs, using an emitter follower 260 whose base voltage is produced across a Zener diode 263 coupled to the input.

Abstract: 1482150 Solar heating systems; tubular heat exchangers P M PRELORENZO 21 Oct 1974 [19 Oct 1973 19 Sept 1974] 45401/74 Headings F4U and F4S A solar heating installation comprises watercirculating solar energy collectors 1 connected by pipes 2 to a heat exchanger 3 in a thermally insulated and unpressurized water storage tank 4 and a consumer circuit 10 connected to a heat exchanger 15 in the tank. Water is circulated through the pipes 2 by pumps 5 controlled by thermistors 6, 7 which are connected in a bridge circuit arrangement whereby the pumps operate only when the temperature sensed by the thermistor 6 is greater than that sensed by the thermistor 7. The consumer circuit 10 includes a mixing valve 11 controlled by a control unit 14 to which is connected an external temperature sensor 12 and a sensor 13 in the circuit 10. A heat pump 18 is actuated by a thermostatic switch 16, having a temperature sensor 17, when the temperature of the heat exchanger 15 falls below a predetermined level. The evaporator 19 of the heat pump 18 absorbs heat from the surrounding water, initiating a thermo-syphoning action, which replaces cold water by warmer water arriving from the region of the heat exchanger 3. The condenser 20 located under the heat exchanger 15 restores this heat at a higher temperature and enables the heat exchanger 15 to fulfil its function. When the temperature sensed by the sensor 17 is such that the heat pump no longer operates, the switch 16 directs electrical current to a heating unit 21. A hot water tank 22 is connected in parallel to the solar collector circuit 2, under the control of temperature sensors 23, 24 and a valve 25. The solar energy collectors may be located on faces of the building to be heated, or on enclosure walls adjacent the building, Figs. 2-4 (not shown). Stored solar energy exceeding the normal requirements may be used for auxiliary purposes such as heating of swimming pools or greenhouses, or energizing a solar motor for driving a watering pump or a generator. The thermal storage tank may be formed from modular units connected together, Figs. 9 and 10 (not shown). Each unit comprises four elements secured together, Fig. 8, each element incorporating a heat exchanger 46-49. As shown, the heat exchangers 46, 49 are to be connected to the consumer circuit and to the solar collectors, respectively, and the heat exchangers 47, 48 act as a condenser and an evaporator of the heat pump.
