Filed: 1967-09-21
Abstract: 1,197,498. Centrifugal liquid and gas pumps. NASH ENG. CO. Sept. 21, 1967, No.42971/67. Heading F1C. In a pumping system, a liquid-ring pump 12 withdraws gas, vapour and liquid through a pipe 10 from a space within, e.g., a heating system, a condenser, a still, an evaporator or a cooker, and discharges these fluids to a separator 16. Liquid is discharged from the separator by a centrifugal pump 24 at a rate which is dependent on the liquid level in the separator. A fall in the liquid level uncovers more inlet openings 32 in a tube 30 to increase the flow of gas and vapour therethrough into the pump 24 and thereby reduce its output, and vice versa. The inlet to the pump 24 is restricted at a position upstream of the downstream end of the tube 30. Air and vapour can be discharged through a pipe 19, and through a second liquid-ring pump 20. When air and vapour is being withdrawn by the pump 24, the pump 20 can be shut down. Liquid for cooling and operating purposes is delivered to the pumps 12 and 20 through pipes 36, 14, 21. Moreover, liquid for condensing purposes may be delivered through a spray head 37. Discharge pipes 19, 22, 27 may be connected to waste or to a collecting chamber for the liquid, the air being vented therefrom. The collecting chamber may contain a cooling coil. Liquid can be returned to the system from the collecting chamber through the pipe 36 and through an optional pipe 44. Liquid from the pipe 44 may be delivered into the separator through a connection 47 and/or through a spray head 48.

Abstract: 983,757. Frequency converters. KANE ENGINEERING LABORATORIES. Dec. 5, 1961 [Dec. 8, 19601, No. 43574/61. Heading H3B. In an apparatus and method for converting electromagnetic energy of one frequency to electromagnetic energy of a predetermined frequency wherein one frequency is related to the other by an odd integer, two resonant modes, one of which is excited by the frequency to be converted, are set up in a cavity, and energy at the predetermined frequency is removed from the second. Cavity 21, in a brass body 16, includes mica separators 26 which divide the cavity into three regions, the upper 27 of which is energized through a coupling aperture 42 and a waveguide 41 by the frequency to be converted. The middle region 28 is supplied with a gas exhibiting an intrinsic electric moment, such as ammonia or a metal-ammonia solution from a reservoir 32 which gas gives a radiation line at the predetermined frequency, and energy is taken from the third chamber 29 by a waveguide 43, an electric field being produced in the chamber 29 by the emission from the gas resulting from pumping by the input frequency. Tuning screws 36, 37 are provided in the bottom cap 18 of the cavity to obtain the desired relation of the two modes The arrangement functions at room temperatures. A cavity arrangement using a material such as diphenyl dipicril hydrazil exhibiting an intrinsic magnetic moment when placed in a strong D.C. field, is described with reference to Fig. 5 (not shown). The length of the cavity is equal to one half the pump wavelength and the crosssectional dimensions are related by the odd integer. The cavity includes tuning slugs and the input is coupled to the cavity by a loop in the centre conductor of a coaxial cable. The strong D.C. field is provided by external polepieces and is arranged to be at right angles to the pump field. Alternative materials for this latter embodiment which may be used in the millimeter region are indium antimonides, chrome doped aluminas and indium garnets. Dimensions and frequencies are exemplified.

Abstract: 1277274 Stamping caps A PODESTA 3 Sept 1969 [4 Sept 1968 6 Sept 1968] 43711/69 Headings B3A and B3Q [Also in Division B8] A composite cap 1 comprises a metallic cap 2 and a resilient liner 3 crimped at its periphery by an inturned section 402. The cap 1 is symmetrical about the vertical axis which terminates the one half of the cap shown in Fig. 1. The cap 1 is formed in separate operations in each of the sets of dies shown in Figs. 4 and 6. In the first operation the metallic cap 2 and the liner disc 6 are inserted into their corresponding recesses in the die 7. The stem 9 carrying the head 10 and the spring jaw 8 then is moved into the die 7. The jaw 8 grips the grooved annular periphery of the liner 6 and the head 10 pushes the central part of the liner 6 into the metallic cap. The periphery of the liner being deformed as it is pulled from the jaw 8 so that it grips the inside of the cap 2. The lower part of the metallic cap skirt is left free from the liner and the cap in this state is placed in the second set of dies, shown in Fig. 6, which are symmetrical about the vertical axis terminating to one half of the die shown. The punching member 16 and the counter punch 15 are moved vertically downwards at the same time, the bottom of the cap being punched into the shape shown in Fig. 1 due to the coaction of the annular ridge 112 and the groove 115. The punching member 16 then continues its downward movement forming the cap against the outside wall of the punch 12. The free end of the metal cap is bent inwards by the shaped heel portion 113 and the annular inclined surface 312 to grip the liner periphery. As the punching member reaches the bottom of its stroke the cap skirt is squeezed firmly on to the liner 6 between the two parallel annular surfaces 116, 312, the heel portion 113 yielding on a buffer member 14 which may be a helical spring. When it is to be placed on a bottle the material of the annular connecting part 302 is drawn down around the lip of the bottle and the inturned section 402 is crimped under the lip to produce a final sealed closure as in Fig. 2 (not shown).

Filed: 1962-11-20
Abstract: 1,030,878. Transistor multivibrator circuits- NORTHERN ELECTRIC CO. Ltd. Nov. 20, 1962 [Nov. 24, 1961], No. 43883/62. Addition to 990,646. Heading H3T. The base electrode of each transistor of a multivibrator is isolated by a diode from its associated timing capacitor while the transistor is conducting and conduction is terminated when the capacitor has charged to such a value that the diode conducts. When transistor Q1 is conducting and Q2 is off, diodes D1 and D2 are cut-off and timing capacitor C1 charges. This continues until point C becomes positive, whereupon the diode D2 becomes conductive and as a result of the regenerative process, transistor Q1 becomes non-conductive and Q2 fully conductive. Capacitor C1 now rapidly discharges through transistor Q2, diode D1 and diode D5, ready to restart the timing operation described when Q1 again becomes conducting. Oscillation may be terminated by momentarily rendering conductive a further transistor Q3 and restarted by a pulse applied to the base of either of transistors 1 and 2.

Abstract: 1,244,831. Ice-making. WINGET Ltd. 24 Sept., 1968 [29 Sept., 1967], No. 44418/67. Heading F4H. Ice-making apparatus comprises a mould 13 which is inclined forwardly at an angle of up to 10 degrees to the vertical and has a plurality of compartments formed in its front face, a manifold 39 for causing water to flow downwardly over the front face of the mould and an evaporator 11 for cooling the mould. A trough 29 collects unfrozen water, which is recirculated to manifold 39 by a centrifugal pump 31, and the ice is harvested by flowing water from a further manifold 59 over the rear of the mould under the control of a thermostat 44 having a probe 43 on the mould. Thermostat 44 also stops pump 31 and the refrigerant compressor 3 during harvesting and energizes a solenoid 45 which depresses the float 47 of a valve 49 to admit water into a tank 7. A valve 51 on the float arm closes an overflow 53 when the float is depressed so that the water can rise to the inlet end of a conduit 58 supplying the manifold 59. The water in the tank is heated by the refrigerant condenser 5 and overheating of the water during the ice-forming phase is prevented by a thermostat 55 which operates solenoid 45 to admit fresh water when the temperature sensed by a probe 57 rises to a predetermined value. Thermostat 55 is arranged to de-energize solenoid 45 before the water reaches the end of conduit 58. The water used for harvesting is also collected in trough 29, the excess flowing to waste through drain 33, and the water remaining in the trough after harvesting is used for the next ice-making cycle. The ice blocks formed in the compartments of the mould are interconnected by webs which break when the released ice falls to the bottom of the apparatus. A thermostat 63 shuts down the apparatus when sufficient quantity of ice has been collected. The float 47 may be replaced by a spring or, alternatively, valve 49 is replaced by a solenoid valve capable of supplying water at a rate sufficiently in excess of that flowing through the overflow as to supply conduit 58. The mould compartments may have a semicircular or triangular cross-section, and the condenser may be air-cooled where no pre-heating of the water is necessary.
