Abstract: 1,196,660. Electrolytically forming a germanide or tinide coating. GENERAL ELECTRIC CO. Oct. 19, 1967 [Nov. 10, 1966], No.47592/67. Heading C7B. A germanide or tinide coating is formed on a metal composition, the metal composition having a melting point of at least 600‹C and least 50 mole percent of said metal composition being at least one of the metals selected from the class consisting of metals whose atomic numbers are 27 to 29, 42 to 47 and 74 to 79 inclusive, the coating method comprising (1) forming an electric cell containing said metal composition as the cathode, joined through an external electrical circuit to germanium or tin serving as anode and fused salt electrolyte consisting of (a) one or more of the alkali metal fluorides or a mixture of one or more of the alkali metal fluorides with one or more of the fluorides of calcium, strontium and barium and (b) from 0À01 - 5 mole percent of germanium fluoride (when using germanium as anode) or from 0À05 - 5 mole percent of tin fluoride (when using tin as anode), said electrolyte being maintained at a temperature of at least 500‹ C but below the melting point of said metal composition in the substantial absence of oxygen and hydrogen in and above the electrolyte and (2) controlling the current flowing in said electric cell so that the current density of the cathode is in the range of 0À01 to 10 amperes/dm<SP>2</SP>. during the formation of the germanide or tinide coating. Ther terms "germanide" or "tinide" designate any solid solution or alloy or intermetallic compound of Ge or Sn with the base metal. The cell generates electric current. The deposition rate of the Ge or Sn may be decreased by inserting some resistance in the circuit or may be increased by impressing a voltage, e.g. to obtain constant current densities during the reaction. Specified fluorides that may be used are those of Li, Na, K, Rb and Cs, e.g. eutectic mixtures of the fluorides of (i) Na, K and Li or (ii) of Na and Li or (iii) of Li and K. The process may be carried out under vacuum or an inert gas atmosphere, e.g. of N, Ar, He, Ne, Kr or Xe. The electrolyte may be purified from C and other impurities by an initial electrolysis. A Ge anode may comprise a rod or be in the form of chips in a Ni or W porous basket. A Sn anode may comprise Sn in a carbon crucible which may be surrounded by tightly woven Mo cloths. The germanide and tinide can be used as hard wear-resistant surfaces. Germanide can be used to develop non- reflective infrared surfaces. Tinided base metal can readily be welded by soft solder.

Abstract: 1,167,921. Valves. CLEAR HOOTERS Ltd. 25 Oct., 1967 [27 Oct., 1966], No. 48223/66. Heading F2V. [Also in Division G3] A vacuum modulating valve for operating a vehicle heater valve comprises a housing 10 carried at the end of a bi-metal cantilever 13. A diaphragm 28 co-operates with valve heads 35, 37 on a stem 34 to connect chamber 20 to engine inlet-manifold vacuum via passage 26 or to atmosphere via passages 32, 33. To select a particular vacuum in chamber 20, flexible stem 49 is rotated by a knob on stem 53 and causes rotation of cam 48 which latter acts on stud 44 carried by a rectangular loop 42 attached to diaphragm 28. The latter is thereby lowered to unseat head 37 to admit vacuum to chamber 20. The head 20 re-seats when the pressure difference across the diaphragm is sufficient to raise the latter against a second bi-metal cantilever 18, which latter has parallel flanges 46 between which is mounted the spindle 49 of cam 48. The cantilevers 13, 18 are arranged so that their free ends approach each other as ambient temperature rises to decrease the vacuum in chamber 20, thereby causing the heater valve to restrict the flow of heating medium.

Abstract: 1406549 Digital transmission; error detection LICENTIA PATENT VERWALTUNGS GmbH 22 Oct 1973 [21 Oct 1972] 49058/73 Heading H4P A circuit for detecting high event density, i.e. number of correct or correctable characters with respect to a possible total comprises a shift register R1 receiving 1's representing an event of one type and 0's for an event of another, clocked by shift pulses not shown. Signals S1 are also applied to mod-2 adder 4 with output from R1, which when 0, signal S7=0 and counter 7 counts forward for each 1 entering R1 hence after N cycles counter 7 indicates number of 1's in R1. There are now three further possibilities :- a 1 enters R1 and a 0 is emitted hence counter 7 is incremented; a 1 or 0 is received and a corresponding 1 or 0 is emitted hence count in 7 remains static; a 0 is received and a 1 is emitted hence counter 7 is switched to backward counting and is reduced by 1. If the count in 7 exceeds a determined number d this is signalled to control line S12 by a unit 10 and counter 8 records the same count and decrements for each 1 on line S7. At zero, counter 8 signals unit 10 which changes signal S12 to 0. In an alternative arrangement, Fig. 2 (not shown), an additional gate (3) blocks for N pulses so that register R1 does not have to be cleared at the start; conversely additional gate (2) is blocked at the end of an operation. AND gate (2) may be alternatively connected to block signals S1.

Abstract: 1300579 Alarm systems EASTMAN KODAK CO 10 Oct 1969 [11 Oct 1968] 49959/69 Heading G4N [Also in Divisions H2 and H3] A signal detector apparatus, e.g. for indicating when electric switches or other apparatus are operating correctly, comprises first and second mutually inductive elements 10<SP>1</SP>, 181, the first element 10<SP>1</SP> being connected in series with an impedance across an A.C. supply and the second element 18<SP>1</SP> being connected to a gating circuit responsive to the signal to be detected, and a threshold detector connected to the junction P<SP>1</SP> between the first element and the impedance. As shown, the gating circuit comprises a rectifier bridge 52 and a controlled rectifier 16<SP>1</SP> which is triggered into conduction by a signal at terminals 42, 44. This causes a secondary winding 18<SP>1</SP> of a transformer 12<SP>1</SP> to have a low impedance so that the voltage across the primary winding 10<SP>1</SP> drops and the potential at junction P<SP>1</SP> is sufficient to cause a threshold device 20<SP>11</SP> to provide a triggering signal to a controlled rectifier 80. The rectifier 80 conducts and lights a neon lamp 82 to indicate the signal detection. It also lights a first-to-fail lamp 84, which when lit so reduces the voltage at a point C<SP>1</SP> that other lamps 84 in similar detector apparatus are not lit should signals be subsequently applied to those apparatus. A reversing switch 86 enables the apparatus to detect the operation of a normally-closed switch or that of a normallyopen switch. In another arrangement, Fig. 2 (not shown), a neon lamp serves as the threshold device 2011 and as the indicating lamp, the lamp 82 being omitted.

Abstract: 1515757 Fluid-pressure servomotor systems ROBERT BOSCH GmbH 9 Dec 1975 [17 Dec 1974] 50502/75 Heading G3P The output of a pump 11 is adjusted by pistons 15, 16, the larger of which is controlled by a valve 28 responsive to speed dependant pressure from an auxiliary pump 33 driven from the same source as the pump 11, the valve 11 having its movement opposed by the pressure in an accumulator 39 charged from the auxiliary pump through a non- return valve 40 and having means to permit fluid from the accumulator to flow into a return line 30. On increased load, the speed of pump 33 falls allowing the valve 28 to connect the piston 15 to a return line 47 and reduce the output of pump 11 so as to avoid stalling. If pump 33 runs at a lower speed for a long period, fluid in the accumulator leaks into the line 47 through a clearance surrounding a flange 42 so that the valve 28 is moved to again throttle communication between the piston 15 and the line 47 and restore delivery from the pump 11. The latter is also controlled by a pressure responsive valve 22. The fall in speed necessary to operate the valve 28 for stall prevention may be made the same for all speeds of operation by replacing a fixed throttle 35 with a variable throttle (54) Fig. 2 (not shown), responsive to pressure in the line 34.
