Abstract: 6 0 2,8 7 4. Capsule-forming apparatus. GUNNELL, R. W. Feb. 15, 1945, No. 3826. Convention date, Feb. 17, 1944. [Class 81(i)] In a method for the formation of capsules, superposed layers of capsule-coating liquid and a cooling liquid of different gravities and mutually immiscible, are maintained within a chamber, a fluid capsule substance is introduced into the coating liquid and caused to pass therefrom into the cooling liquid. The coating liquid, e.g. gelatin-glycerine solution, may contain a substance, e.g. soap, sulphonated higher alcohols, &c., reducing the surface tension at its interface witn the cooling liquid, e.g. kerosene, naphtha, petroleum etner, &c., mixed with carbon tetrachloride, perchlorethylene, &c. If desired, the latter liquids may constitute an intermediate layer, with an upper layer of water, or water admixed with alcohol, acetone, &c. In Fig. 1, the content substance passes to nozzles 11 in the chamber via cooling- jacketed pipes 12, being advantageously cooled, say, to 10-20‹F. Each nozzle is formed with a slidable pin 18 adapted to close its orifice when not in use. Regulating valve controls 26 are shown, the drops on formation being visible through windows 29. The coating liquid is supplied from receptacle 66 provided with a heater 65 and thermostat 68, stand pipe 62 ensuring the necessary hydrostatic head of liquid. The temperature of the gelatin is maintained within the chamber by heating strips 32 lying parallel to the rows of nozzles 11. The cooling liquid 35 is maintained at 40-60‹F. by cooling cells 36 in the form of hollow plates through which a refrigerant passes via pipes 38, 37, 41. The capsules reaching the surface 42 of the liquid are removed by a rotating paddle 43 over a weir 45 to a perforated draining plate 46 and collecting receptacle 47. The liquid draining into vessel 48 is pumped through a cooling coil 52 back to the chamber through lines 56 having upwardly directed openings 57.

Title: Tuning and detection set-up for radiotelegraphy, radiotelephony or radio-broadcast receivers
IPC: H04B1/66
Filed: 1960-02-05
Abstract: 927,801. Valve circuits for frequency-selective amplification; valve pulse-generating circuits. R. L. L. G. GILBERT. Feb. 5, 1960 [Sept. 2, 1959], No. 4117/60. Class 40 (6). The intermediate-frequency section of a radio receiving circuit comprises a valve 3 having a grid 9 to which incoming I.F. signals are applied and a grid 13 to which a rectangular-pulse gating signal is applied, the repetition frequency of the gating pulses being in excess of the highest modulation frequency contained in the I.F. signal, followed by a narrowband-pass filter comprising a crystal 14 tuned to the I.F. and having a pass band considerably narrower than the band width of the received I.F. signals, there being a high-valued resistor 18 connected in series with the crystal and a circuit comprising diodes 20, 201 adapted to short-circuit resistor 18, this latter circuit being controlled by pulses from the generator of the above-mentioned gating pulses so that during the intervals when valve 3 is passing signals resistor 18 is short-circuited and the crystal 14 has a high effective Q while when the valve 3 is blocked, resistor 18 is not shortcircuited and the effective Q of the crystal becomes very low. Tuned transformers 11, 12 and 15, 16 having wide pass-bands are arranged on either side of the crystal 14; the signal derived from tuned secondary 16 is amplified at 5, passed through a further broad-band filter circuit 6 and detected at 7. Incoming modulated signals as shown at a, Fig. 13, are chopped by the valve 3 and then converted to a succession of triangular groups of oscillations at I.F. with a slow build-up due to the high Q of the crystal during the " on " periods of the valve and a rapid decay due to its low Q during the " off " periods, the envelope of these triangular groups corresponding to the original modulation. The triangular " ripple " superimposed on the original modulation may be considerably reduced by connecting three circuits, each as shown in Fig. 11, in parallel, Fig. 1 (not shown), and so synchronizing the respective gating- pulse generators that the phase of each is displaced 120 degrees from that of each of the others. Generating three-phase rectangular pulses. Fig. 12.-The time-constants of the cross-coupling connections of three substantially identical multivibrators I, II, III are so arranged that positive-going pulses with a mark-space ratio of 2 to 1 are produced at the anode of the lefthand valve of each. The commencement of a positive-going pulse at the left-hand anode of multivibrator I is applied through capacitor 28 to terminate a positive-going pulse at the lefthand anode of multivibrator II. Multivibrator II is similarly coupled through capacitor 28<SP>1</SP> to multivibrator III. The three multivibrators thus produce positive pulses separated from each other by one-third of a pulse period. It is stated that the first multivibrator could similarly be synchronized from the third.

Abstract: 876,517. Footwear injection moulding machines. BRITISH UNITED SHOE MACHINERY CO. Ltd. Feb. 11, 1958 [Feb. 11, 1957], No. 4354/58. Class 87(2). In an injection moulding machine for moulding a shoe bottom member on to a shoe upper the injection of plastic material is terminated when the mould cavity is full by control mechanism operated by movement of the support 66 for the upper 64 effected by the pressure of the injected material. The injection mechanism comprises a piston 194 operable in a cylinder 192 to which plastic material is fed by a screw 208 to retract the piston until an arm 206 on the piston rod 201 operates a micro-switch (not shown) to de-energize the motor driving the screw 208. The machine comprises two mould assemblies (only one of which is shown in Fig. 2) mounted for movement by an operator along guide rails 30 between separate loading stations and an injection station located therebetween. Plastic material is injected into the mould cavity through a nozzle 152 which communicates with a tube 154 projecting rearwardly from the sole-shaped mould member 56. In order to terminate the injection when sufficient plastic material has been injected into the cavity, the pressure build-up within the cavity is arranged to overcome the force of a spring 124 and to move the shoe forwardly relative to the side mould members 52, thus effecting a slight clockwise movement of the latch lever 104 to operate a micro-switch 146. During the operation of the screw conveyer 208, the bore 197 in the block 190 is kept closed by a rotary valve 212, the opening of this valve being effected on initiation of the means for causing the piston 194 to commence its downward movement. The circuit arrangement is such that this advancement of piston 194 can only be initiated after the cylinder 192 has been loaded with a predetermined quantity of plastic material. Specification 704,844 is referred to.
