Title: Gas fuelled candle
IPC: F23D14/28
Filed: 1963-12-20
Abstract: 1,065,247. Gas burners. E. M. KOMMER. Dec. 20, 1963 [Dec. 21, 1962], No. 50378/63. Heading F4T. A gas burner resembling a candle comprises a reservoir 1, Fig. 4, for butane or propane under pressure and a valve 23 controlling a passage between the reservoir and a burner 5 and adapted to be opened against the action of a spring 37 either by rotating a tip 6 or by pushing the burner 5 downwardly. The valve is opened by rotating the tip when it is desired to allow the gas to flow from the reservoir to the burner and it is opened by pushing the burner 5 downwardly when it is desired to refill the reservoir with butane from a supply container. The burner 5 is secured in a central bore 28 in the valve. The valve 23 is slidably mounted in a housing 12 and comprises a neck portion 31 surrounded by a resilient ring 20 secured to the housing and closing a number of radial openings 33 extending from the neck 31 to the bore 28. When the valve is moved downwardly the inner marginal portion of the resilient ring 20 bends downwardly to uncover'the radial openings 33. The tip 6 is secured to a nut 36 threaded on the housing 12 and has an insert 35 made of a material of low melting- point and disposed in abutment with a collar 34 on the burner. Consequently, when the tip is rotated the burner is pushed downwardly to open the valve. A gasket 40 is provided on the collar 34 to serve as a seal for the charging tube of a supply container when the latter is telescoped over the burner and is pushed downwardly to open the valve. In the modification shown in Fig. 5, the valve comprises a hollow stem 49 which is slidable and rotatable in a valve housing 12b and carries at its lower end a body 61 carrying a gasket 62 adapted to seat on a seating 48 on the valve housing 12b. The body 61 is threaded into a sleeve 36 which is slidable but non-rotatable in the body of the fuel reservoir 1. The upper slit end of the sleeve 63 abuts the valve housing. The tip 6 is rotatably mounted on the valve housing 12b and its upper end surrounds a ball-valve housing 55, 56 on the upper end of the valve stem 49. The co-operating surfaces of the ball-valve housing and tip are hexagonal to allow longitudinal movement and prevent angular movement. Angular movement of the tip therefore causes the valve body 61 to be screwed into the sleeve 63 to open the valve. The angular movement is limited by an abutment 47 on the valve housing. When the valve is opened by pushing the stem downwardly by means of a supply container the sleeve 63 moves downwardly with the valve. The ball valve at the upper end of the stem cuts-off the supply of gas if the burner is upset. In another embodiment, Figs. 2, 3 (not shown), a fuel container has a depressable charging tube extending through an aperture in a tip having a skirt which surrounds the fuel container and is threaded into a base on which the fuel container is placed. When the tip is screwed downwardly it engages a collar on the charging tube to depress the latter and allow the fuel to discharge through the charging tube.

Title: Freeze tunnel
IPC: F25D29/00
Filed: 1974-12-06
Abstract: 1494104 Tunnel systems CRYOGENICS CORP OF AMERICA 6 Dec 1974 [10 Dec 1973] 52943/74 Heading F4H [Also in Division H2] A tunnel refrigeration system comprises a number of modular units joined together by connectors 30 to form pre-cooling zones 12 and 14, and freezing zones 16, 18, 20, with load and discharge zones 22, 24 disposed at opposite ends of the tunnel. A conveyer 26 comprising an endless flexible bolt 40 on supports 50 passes through the zones, with an adjustable variable speed motor 42 driving the bolt. Each modular unit has side walls 32 and 34, a top 36 and bottom 38 formed of spaced sheets 38a, 38b of stainless steel with insulating foam 38c therebetween. A copper circular cooling coil is disposed in each zone; each coil having an inlet and outlet manifold joined together by a tubular run 74, 76, 78. An annular plenum chamber 85 is formed about each coil, an inner wall 88 of said chamber being adjacent the lower end of each coil. A fan 60 forces air downwardly from the coil through the spacing between 85 and 88 and upwardly through perforations in the belt back to the fan. Baffles (92, Fig. 4) extend across the tunnel in order to separate the zones. Zone 12 is preferably maintained at -20‹ F., zone 14 at -50‹ F., zone 16 at -100‹ F., zone 18 at -200‹ F. and zone 20 at -250‹ F. A container (100, Fig. 8) of liquid nitrogen, CO 2  &c. is connected to the inlet manifolds of the coils. The coils in zones 16 and 20 are connected in series, as are the coils in zones 14 and 18. The two sets of coils are themselves connected in parallel to a single exhaust line (114, Fig. 8). Under normal conditions (i.e. when defrosting is not required in zone 12), the cooling medium flowing through the exhaust line (114) pases through the cooling (62a) in zone 12 to a vent line (120, Fig. 8). When the coil in zone 12 becomes iced up, the cooling medium in exhaust line (114) passes directly to the vent line (120) by-passing the said coil. At the same time a bank of heating elements are energized for a predetermined period of time to defrost the coil. An electric control system is described in detail for operating the tunnel refrigeration system and the defrosting operation. The electric control circuit includes a defrost controller (128) in the form of a resistance bridge network including a first thermistor (136) mounted in the vapour exhaust line (120), through which the cooling medium vapour is exhausted to atmosphere, and a second thermistor (138) disposed inside the precooling zone 12. When frost on the surface of the coil in zone 12 creates a predetermined temperature differential, the resistance bridge becomes unbalanced, activating the defrost cycle.

A Air measurement Line 9a is closed, cock 5 and 6 to a twin choke carburetter C are closed and the static pressure is established in chamber 1 and tube 2 of a flowmeter H provided with a number of different scales 3 corresponding to the number of different calibrated jets in a drum unit G. 1 Calibration of a jet A jet to be tested is placed in a tube E and one of the calibrated jets in drum unit G, Figs. 2-4 (not shown), is selected, cock Ra is opened, compressed air closes a valve Va and orifice 7 to shutoff passages 8, 9 and 11, and air, reduced in pressure by a reducer Da, passes through line A 2  and jets in drum unit G and at E and any deviation in the level in flowmeter H will give a comparison with the calibrated jet so that the jet under test at E can be calibrated by interpolation. 2 Effective cross-section of Butterfly valves Cock Ra is opened, valve Va and orifice 7 are closed and either or both cock 5, 6 are opened and the flow past one or both the butterflies 3, 4 varies the pressure in line 11 and readings taken at flowmeter H gave a comparison with a calibrated jet in drum unit G and the cross-section for the air admission through the butterflies 3 and/or 4 can be deducted by interpolation. B Petrol measurements Cock Rb is opened, valve Vb is opened to allow a closed tank I, provided with a level indicator Z 1  to be supplied with petrol, the tank I is then pressurized through a pressure reducer Db and line 25, cock 22 being closed, to supply petrol via line 20a 20 to tube T and tube 17, cock 18 being open to lift a float 26 to close, by a needle valve 27, a duct 19 leading to a tank L. Cock 18 is now closed and cock 22 opened to allow petrol to settle to a level 0-0. 1 Loss of petrol in the carburetter When the carburetter C has been filled with petrol, cock 18 is closed and if the reading of a pressure indicator 23 falls there is a leak in the carburetter C. Cock 18 is then reopened and the time of descent of petrol in tube M indicates the leak magnitude. The same result will be obtained if cocks 18, 22 are opened. 2 Petrol consumption per accelerator pump stroke Cocks 18, 22 being open, each stroke of the accelerator pump will cause the petrol level in tube M to descend and hence the amount of petrol delivered per stroke can be obtained. A device is provided for supporting all types of carburetters, Figs. 5-7 (not shown).

Abstract: 1,191,729. Pulse oscillators. GENERAL ELECTRIC CO. 6 Dec., 1967 [8 Dec., 1966], No. 55487/67. Headings H3P and H3T. [Also in Division H2] A blocking oscillator 1 has a bias supply connected to the control electrode of the switching element 11 so as to tend to render it conductive, and a non-linear element, e.g. a Zener diode 21, arranged to isolate the feedback winding 16 from the control electrode as the start of a conducting period. As the transistor 11 becomes conducting, the induced voltage in winding 16 forward biases diode 21 to connect this winding to the base electrode, thus providing positive feedback until the transistor saturates. During the part of the cycle when the transistor is coming out of saturation the diode operates in its Zener mode. The oscillation may be stopped by applying a suitable bias at point e c . In a modification, Fig. 2 (not shown), this bias is applied to a transistor (51) shunting the winding 16 and diode 21. The oscillator may be used to trigger thyristors 31, 31<SP>1</SP> in a bridge inverter, a similar oscillator 2 being employed to trigger the other two thyristors 34, 34<SP>1</SP>. In an alternative embodiment, Fig. 3 (not shown), the oscillator is employed to trigger a triac for controlling the supply of an A.C. to a load. In order to sharpen the output pulses, a capacitor 27 or 27<SP>1</SP>, is charged by the oscillator until an avalanche diode 27 or 27<SP>1</SP> breaks down to discharge the capacitor through the thyristor control circuit. In place of the transistor 11 as the switch, a gate turn-off device, a silicon controlled switch or valve may be used.
