Title: Improvements in or relating to exothermic catalytic gas reactions
IPC: B01J8/02
Filed: 1928-11-24
Abstract: 325,028. Harter, H. Nov. 24, 1928. Catalytic apparatus.-Apparatus for exothermic catalytic gas reactions comprises a heat-insulating cylinder f situated between the reaction cylinder b and the pressure-resisting wall a. The reaction gas flows through the space between the wall a and the heat-resisting cylinder f before entering the reaction space, while an independent current of cooling medium is circulated by means of a pump l through the space between the heatinsulating cylinder and the reaction cylinder. In the illustrated modification the cooling medium is of the same composition as the reaction gas and the inlet tube c is common to both circuits. In another modification the cooling unit is entirely separate from the reaction gas circuit.

Title: Improvements in or relating to liquefied-gas containers
IPC: F17C13/12
Filed: 1959-10-13
Abstract: 919,617. Storing liquefied gases; forcing liquids by gaseous pressure. LINDE'S EISMASCHINEN A.G. GES. FUR. Oct. 13, 1959 [Oct. 18,1958], No. 34681/59. Classes 8(2) and 102(2). In a container 1 for liquefied gas, the necessity for allowing adequate free volume for liquid expansion, is allocated by an overflow line 11a 11b and an evaporator 5, co-operating with an automatic pre-set pressure valve 9, gas being fed back to the free surface 2, of the liquid by the line 6. An outlet 10 in the base of the container 1, feeds the overflow line 11a and also a branch line 4 containing a valve 3 independently controlling the supply of liquid gas to the evaporator 5 for liquid ejection, when required, through the supply line 8. The overflow line may be taken out of the side of the container 1 at the critical height 12 or alternatively could penetrate the outlet 10 in the base forming a pipe coaxial with 10 and reaching up within the container 1 to the critical height 12. The overflow line 11a should be in close contact with the container 1 to prevent premature discharge to the evaporator 5 and lines 6 and 11b should be close together and away from the container 1 to reduce recirculation losses and to allow sufficient gas to be presented to the overflowing liquid to avoid siphoning liquid from said container.

Title: Process for producing a dry product for food preparations
IPC: A23L23/10
Filed: 1975-08-20
Abstract: Dry products for producing instant food powders which swell and dissolve without forming lumps in water or aqueous liquids are obtained by mixing edible hydrophilic substances with water or aqueous liquid to form a crumbly mass, which is then mixed with starch, modified starch or a mixture thereof with up to 25% by weight of another high molecular plant-origin binder. The homogeneous mass is conditioned, comminuted if necessary, dried and sieved. The ratio of hydrophilic substance to water and starch is chosen in such a way that after conditioning, an agglomerate is present in which the starch particles as cores are enclosed by a layer of hydrophilic substance.

Title: Improvements in or relating to superheterodyne receivers
Inventor: BICKERS ARTHUR
IPC: H04B1/26
Filed: 1963-09-06
Abstract: 1,094,653. Superheterodyne circuits. PLESSEY-UK Ltd. Sept. 4, 1964 [Sept. 6, 1963], No. 35337/63. Heading H3Q. In a superheterodyne receiver in which the local oscillator 3 comprises a digital frequency synthesizer with facilities for stepping from one channel to an adjacent channel, breakthrough of an unwanted signal can occur due to the intermodulation in the mixer 2 of a harmonic of the unwanted signal with one of the harmonics generated in the local oscillator. To prevent this a switch S3 is provided whereby the local oscillator frequency can be switched to that for an adjacent channel and so change the intermediate frequency generated. Switches S1, S2 ganged with the switch S3 replace the I.F. filter 4 by a filter 5 tuned to the new intermediate frequency. Alternatively a double superheterodyne (Fig. 2, not shown) may be used: in this the first oscillator comprises a digital synthesizer as described above, and the pass band of the first I.F. amplifier is made wide enough to pass either I.F. signal. The bandwidth of the second I.F. amplifier is made narrow, the switch changing the frequency of the first oscillator being ganged with a further switch which causes the frequency of the second oscillator to be shifted to an extent equal to that by which the first oscillator frequency is changed. The second oscillator preferably uses switched crystals.

Abstract: 1,143,210. Controlling burners. CONTROLS CO. OF AMERICA. 10 Aug., 1966 [13 Sept., 1965], No. 35736/66. Heading F4T. In a burner ignition and fuel control system an igniter 12 having spaced electrodes 11, 13 which also act as a flame sensor is connected in the secondary circuit of a transformer 16 of which the primary coil 20 is connected to an electrical source 22 through a pulsing circuit 24 and a fuel control valve 14 electromagnetically operated through a coil 15 connected in an emitter-follower circuit including a transistor 40. When ignition voltage is applied to igniter 12 with no flame, a high voltage is applied to a gate 52 of transistor 40 rendering the latter conductive to pass sufficient current to open valve 14 and when a flame occurs the ionization potential at the electrodes 11, 13 results in a reduction in potential of gate 52 to reduce the current to a holding value. A silicon controlled rectifier 64 controls current flow in a path 62 of a voltage sensitive circuit 60 so that if ignition fails a shunt circuit to ground is established around valve coil 15 to close the valve and cause a lock-out condition which can be reset by the momentary opening of a switch 80 in the main supply line.

Abstract: 1,181,580. Doped zinc oxide. AGFAGEVAERT A.G. 4 Aug., 1967 [5 Aug., 1966], No. 35942/67. Heading C1A. A doped zinc oxide is prepared by vaporizing a zinc oxide which has already been doped, the vaporization being carried out in the presence of a reducing gas and/or an inert gas so that decomposition and reduction of the zinc oxide occurs and burning the vapours of zinc and doping material so produced to form the doped oxide product. Preferably the initial doped oxide is mixed with metallic zinc and contains a higher concentration of doping material than is desired in the final product. The preferred reducing gas is hydrogen and the oxide used is preferably doped with lithium and sodium. The combustion step may be performed in a highly turbulent flame to ensure good mixing. The product may be subjected as a smoke to a thermal after treatment at temperatures of 500-900‹ C. for a time of 10-200 secs. The initial ZnO may be obtained by sintering a mixture of zinc oxide and for example Li2CO3 or Na2CO3. The particle size of the final product is between 0À05 and 0À1 Á.

Abstract: 1,271,680. Multi-disc brakes; hydraulic operation. BORG-WARNER Ltd. 18 July, 1969, No. 36417/69. Headings F2E and F2F. A brake actuating assembly includes two pistons located in the same cylinder and hydraulically operated in succession so that the brake is smoothly applied, initially with a certain force and subsequently with a greater force. As shown, rotary friction elements 10B are associated with the ring gear of an epicyclic gear train at the output end of an automatic transmission, while friction elements 10A are secured to the housing of the transmission. A first piston 11 slidable in an annular cylinder 14 is provided with a portion 18 engageable with the right-most friction element 10A and is urged to the right by a spring 20. Between an axially-extending wall 17 of the piston 11 and the outer wall of cylinder 14 is accommodated a member 12 provided with an axial extension 19 which engages the cylinder wall; the extension 19 has an orifice 16. Finally, a second piston 13 is accommodated between extension 19 and the inner wall of cylinder 14. An hydraulic fluid supply port 15 is provided between the first piston 11 and the member 12. In operation, the brake 10 is used to effect a gear change by stopping the ring gear. Hydraulic fluid is introduced, when the particular gear change is required, through supply port 15, so initially piston 11 is forced to the left, the brake being thereby applied with light force. At the same time, fluid flows through orifice 16, slowly filling the space to the right of piston 13, until piston 13 also moves to the left. The effective piston area is thereby doubled, so the brake is now applied with double the force.
