Abstract: 509,740. Infusion apparatus. REINHOLZ, F. Nov. 30, 1938, No. 34900. [Class 129] A coffee, tea or like infusion apparatus comprises a boiler a with an immersible coffee basket m having a closed bottom t which in the upper position co-operates with an internal flange piece s to form a partition across the boiler so that the coffee is not subjected to any direct steam action before being immersed ; the basket is lowered into the liquid and then rotated, for instance, by a hand crank h and bevel gearing g which drives a screw-threaded spindle i, whereby a pin w mounted on the basket by a bracket piece u is caused to descend to the exit of a slot l in a fixed tubular guide k for the basket, whereupon the pin engages the end of the screw thread to rotate the basket. The basket, Fig. 2, is of a parallelogram form having only the inclined inwardly set end walls n perforated. A relief valve c allows steam to escape after passing through tubes f, e. The steam may pre-heat the coffee in a following apparatus.

Abstract: 1,107,396. Gas turbine jet engines; turbine rotors. CURTISS-WRIGHT CORPORATION. Aug. 17, 1965, No.35234/65. Headings F1G, F1J and F1T. Fig. 1 shows a gas turbine lift engine which can be installed in an aircraft wing. The engine rotor 16 may be a single casting or, as shown, comprises laminations 26 of sheet metal, flat forgings or thin castings which are bolted to stub shafts 28, 30. The laminations 26 are apertured to afford axial-flow lift fan blades 14, axial-flow compressor passages 10 and radial-flow turbine passages 12. An annular combustion chamber 58, which may be subdivided by circumferentially spaced walls, receives compressed air via stator vanes 57, ducting 56 and openings 60, and delivers gas via nozzles 66 to flow radially inwardly through the turbine passages 12. The nozzles 66 and any subdividing walls of the combustion chamber may be made hollow and cooled by passing fuel through them on its way to the injection nozzles 62. The rotor 16 is cooled by the compressor air and fan air passing through it. The compressed air may be pre-heated in a heat exchanger by exhaust gas. A rotor similar to the rotor 16 but with the fan blades 14 omitted may be used in a turbo-jet engine or a turbo-fan or turbo-prop engine in which the fan or propeller is driven from the rotor through reduction gearing or directly driven from the free spool of a twin-spool engine.

Abstract: 1511727 Regenerating waste photographic developers by electrodialysis NIPPON EVR Ltd 27 Aug 1975 [30 Aug 1974 24 Jan 1975 26 Feb 1975] 35359/75 Heading C7B Waste developers used for processing silver halide colour or black-and-white photographic materials are regenerated by charging the waste developer e.g. from supply line 7 into the cathode compartment 5 and an electrolyte solution e.g. from supply line 8 into the anode compartment 6 of an electrolytic cell 1 in which the cathode 2 and anode 3 are separated from each other by an anion exchange membrane 4. Alternatively an electrodialytic cell 11, Fig. 2, may be used in which the cathode 12 and anode 13 are separated by anion exchange membranes 14 and cation exchange membranes 15 arranged alternately forming a plurality of deionation compartments 18 and enionation compartments 19 between the cathode and anode compartments 16, 17, and the waste developer is charged e.g. via supply line 20 into the  cathode compartment 16. The effluent from  either cathode compartment 5 or 16 of cell 1 or 11  may be then charged e.g. via lines 9 or 24 and 22 into the deionation compartments 18; and the effluent from the anode and enionation compartments 6, 17 and 19 of cells 1, 11 e.g via lines 10, 25 27 may be treated with chlorine or a hypochlorite. In a modification using both cells 1, 11 connected to each other by piping, the first cell 1 may be separated by a cation exchange membrane, the waste developer being charged into the cathode compartment of the first, whilst electrolyte solution is charged into cathode compartment 16, enionation compartments 19 and anode compartment 17. Waste developer can be regenerated even by charging it first into the deionation compartments 18, then from effluent line 26 into the cathode compartment 16. The electrolyte solution may be NaOH, KOH, Na 2 SO 4 , K 2 SO 4  or H 2 SO 4 . The cathodes 2, 12 may be of Fe, Ni, Pb, Zn or stainless steel; the anodes 3, 13 may be of graphite, Pt, Pt plated Ti, Pb or magnetite. The anion exchange membranes 4, 14 may be of the strong base type and the cation exchange membranes 15 may be of the strong acid type.

Filed: 1922-12-29
Abstract: 213,014. Tanier, V. Dec. 29, 1922. Gaseous-fuel furnaces.-A gas-fired furnace for heating retorts &c. is divided into two halves by a longitudinal partition 1 in whch are formed ducts 4, 4<1>, 5, 5<1> for the gas and air respectively, opening into the furnace through passages 17, 18 so that by blocking the passages 17, 18 on either side one half of the furnace can be isolated from the other. The air enters the duct 4 through a conduit 14 and regenerators 7, and the gas the duct 5 through a conduit 13 and regenerators 8, each of these conduits and sets of regenerators being divided into two by a transverse partition 21. The air and gas are admitted at one end of the furnace only and the combustion products pass through openings 22 in the partition 21 and through the ducts 4<1>, 5<1> in second half of the furnace into the regenerators at that end. When these have been thus heated the course of the air and gas is reversed. The lower part of the partition 1 is hollow to receive spilt metal, which is thus prevented from running into the regenerators.

Filed: 1961-10-05
Abstract: 945,422. Automatic exchange systems. STANDARD TELEPHONES & CABLES Ltd. Oct. 5, 1961 [Oct. 6, 1960], No. 35909/61. Heading H4K. An electrically controlled system such as an automatic exchange, has two parallel acting electronic control devices F1, F2 each intended to receive the same information, each device having an associated test circuit P1, P2 which if it detects a fault inhibits the output of that device. The outputs of F1 and F2 are connected to parallel-acting control outputs via OR-gates M1, M2. Thus R1, R2 receive only outputs from the devices F1 and F2 for which faults are not detected. The devices P1, P2 may be code-checking devices, an incorrectly coded signal causing an error signal to cut-off a transistor supplying bias potential to bistable storage circuits in F1, F2 respectively to inhibit their outputs.

[Also in Division G3] A circuit for providing constant current in a load 1 such as a battery up to a determined voltage after which the voltage is maintained constant or at some gradually rising value comprises a current measuring circuit 12, 14, 17 18 producing a voltage which is compared with that across a Zener diode 15, the error controlling an amplifier 22, 24 which varies the current in a transductor control winding 8 or field winding 11 of a generator. The circuit is arranged so that transistor 24 functions as a switch. A diode 27 provides a discharge path for the electromagnetic energy in the winding 8(11) and another diode 28 limits excessive voltage across the transistor 24. When the potential across the voltage measuring circuit 13 exceeds that across a current measuring circuit 14 a diode 21 blocks and another diode 16 unblocks taking over the control of the circuit. The circuit may have provision for manual control. The resis tor 13 may have an amplified ripple fed into it (Figs. 10-12, not shown) to accentuate the switching function of transistor 24.

An electrode is made on a silicon semiconductor body by melting tin in contact with the body and with a small quantity of a material which is at least partly of aluminium and contains no element other than aluminium, silicon or tin; the tin dissolves the material and part of the body, and on solidification a layer of silicon containing aluminium is deposited contiguous with the rest of the body. A pellet 7 of the material (preferabjy Al/Si eutectic alloy) is placed in a tapered recess in one part of a jig 1, the recess being filled with a pellet of pure tin 8. A silicon wafer 9 is held between the two sections of the jig and another pellet of tin 10 (which may contain a little antimony as incidental impurity) placed in a hole in the upper section. A number of such jigs are loaded into a boat and pulled through a furnace where they are in succession heated and then cooled. The tin 8 melts and dissolves the material 7 and a part of the silicon, so that on cooling, the pit formed in the silicon is filled with a layer containing aluminium. The tin forms ohmic connections on the two sides of the wafer, which is then etched and sealed as usual. The material 7 may be Al, Al/Sn alloy or Al/Sn/ Si alloy.
