Title: Improvements relating to apparatus for recording electrical energy consumption
Inventor: HUTTIG HANS
IPC: G01R11/60
Filed: 1965-04-21
Abstract: 1,098,934. Recording electrical energy consumption. LICENTIA PATENT-VERWALTUNGS-G.m.b.H. April 21, 1965, No. 16822/65. Heading G4D. In apparatus for recording the maximum values of the consumption of electrical energy over a long period of time, the maximum values are measured over successive short periods by a meter which starts at the beginning of each short period and delivers pulses for successive units of energy to successive counter stages so that the number of stages operated represents the energy. The long period may be three months and the short measuring period 15 minutes. The short period is set by operation of a time switch contact 11 which energizes solenoid 12 and connects a pulse transmitter to the meter. The pulse transmitter consists of a cam which in rotating closes two contacts 24, 25 alternately. A complete revolution represents 20 kWh and this gives two pulses. The transmitter spindle is automatically returned to the starting position at the end of the measuring period. The counting stages 0-9 consist of relays, the alternate pulse leads being connected one via the normally closed contact (0<SP>1</SP>) to the relay coil and the other via the normally open contact (0<SP>11</SP>) to the next stage (1). Successive pulses cause the stages to operate in turn. Each relay serves to step a counter which indicates the number of times it has been operated and from this it can be determined the number of times each count was reached.

Filed: 1940-11-29
Abstract: 551,305. Hydroxy dithio-naphthoic acids. WINGFOOT CORPORATION. Nov. 29, 1940, No. 17080. Convention date, Nov. 29, 1939. [Class 2 (iii)] [Also in Group V] Hydroxy dithio-naphthoic acid alkali salts are prepared by reacting in a common solvent a naphthol, an alkali metal hydroxide and carbon disulphide. It is preferred that the reaction be carried out under substantially anhydrous conditions, and the water formed in the reaction be removed as it is formed. An alternative procedure comprises the separate preparation of the alkali metal naphtholate which is then reacted with carbon disulphide. Solvents mentioned include ketones, pyridine, mixtures 'of aromatic or aliphatic hydrocarbons with acetone or other ketones, and mixtures of ethers and ketones. Numerous examples are given using as starting materials both α-, and #-naphthol. Varying reaction conditions are exemplified. If alkali metal is used instead of an alkali metal hydroxide, the formation of water in the reaction is avoided. The alkali metal salts prepared as above described may be converted into the free acid by treatment with a dilute mineral acid, or they may be converted into basic zinc salts by treatment with an aqueous solution of zinc sulphate, or they may be converted into cyclohexylamine salts by reaction with ammonium chloride followed by treatment with cyclohexylamine.

Title: Production of semiconductor materials

Abstract: 947,888. Semi-conductor devices. KABUSHIKI KAISHA HITACHI SEISAKUSHO. May 11, 1961 [May 11, 1960], No. 17266/61. Heading H1K. An N-type or photo-conductively activated cadmium chalkogenide is made by heating the chalkogenide with a donor or photo-activating impurity and a molten flux containing at least two halides selected from the halides of alkali metals, alkaline earth metals and cadmium. The melting points of the flux mixtures used being lower than those of the component halides the heating can be performed at temperatures lower than those used with a single halide flux. This causes a reduction in the photoconductive response time of the resulting material, and the flux mixture by suppressing crystallization results in a product of smaller grain size. In an example 1 mol. of cadmium sulphide is heated in inert gas with a mixture of 40 mol. per cent sodium chloride and 60 mol. per cent cadmuim chloride containing between <SP>1</SP>/ 10  and 1/ 2  mol. of chlorine. The resulting crystals are mixed in 1 : 1 volume ratio with resin and placed between non-ohmic electrodes 300Á apart. The resulting I-V curve is shown at I in Fig. 4, the voltage at which the slope suddenly increases being much higher than in a comparable device (curve II) made from cadmium sulphide prepared in a single halide flux. Similar results are obtained using a cadmium chloride-potassium chloride flux and are attributed to the reduced grain size. A photo-conductive cadmium sulphide activated with copper or chlorine is prepared by heating to 400-500  C. using a flux containing 60 mol. per cent sodium chloride and 40 mol. per cent cadmium chloride to produce a particle size of 1-10Á. The photo-electric response rate of the resulting material is indicated by curve 1 in Fig. 5. Curve 2 is a similar curve for material prepared with a potassium chloride cadmium chloride flux, and curve 3 for material prepared with a single halide flux.

Abstract: 437,538. Valve circuits for wireless reception; discharge apparatus. COSSOR, Ltd., A. C., and POLLOCK, R., Highbury Grove, London. June 13, 1934, No. 17515. [Classes 39 (i) and 40 (v)] The muting bias applied to a signal detector is neutralized by the rise in potential of an electrode of a glow discharge tube used as a tuning indicator when the received signal strength reaches a predetermined level. As shown two carrier frequency amplifiers V1, V2 receive A.V.C. grid bias from the diode rectifier A1 which they feed and the low frequency amplifier V3 receives the output of a diode detector A2 also fed from the valves V1, V2. The negative muting bias is supplied to the anode A2 through resistances R2, R3 from a resistance R1 in the common cathode return lead, the resistance R3 acting as the diode load resistance. The glow discharge tube N comprises a rod cathode C, anode A, auxiliary anode K and a "gate" electrode G arranged about half way up the cathode C its conductor support being insulated so that the electrode is unaffected by the discharge until it rises to a predetermined point on the cathode. The cathode potential is adjustable by a potentiometer RH carrying current from the main anode source and a small discharge occurs between the cathode and the electrode K over a high resistance R5. The main anode A is connected through a resistance R12 to the low potential end of a resistance R11 common to the anode circuits of the A.V.C. controlled valves V1, V2. As the signal strength increases the current in resistance R11 falls and the potential of the anode A rises producing a glow discharge to the cathode C which increases in length along the cathode. This affords a visible tuning indicator and when the discharge reaches the electrode G, the latter becomes positive and being connected to the junction of resistances R2, R3, neutralizes the negative muting potential on the anode A2. The resulting flow of rectified current in the load resistance R3 prevents the application of an excessive positive bias to the detector. Specification 413,388 is referred to.

In an electric switch, in which the contacts are made by the application of a potential to an electrostrictive element, the electrodes to which the potential is applied are shunted by an ionisation chamber to render the operation of the switch sensitive to radio active radiation. The electrostrictive element 5, Fig. 1 of barium titanate is mounted between electrodes 4 and 6 which are supplied with a potential from the source XY. A contact 2 attached to electrode 4 contacts a fixed contact 1 when the potential is applied to the electrodes. The chamber 3 may be filled with argon and coated internally with boron, or alternatively can be filled with boron tri-floride. With the potential adjusted to move the switch it is subjected to radiation whereby, the gas ionizes, reducing the potential, and the switch opens. In Fig. 2, the switch is arranged in a circuit for measuring the radiation intensity. On application of a potential the switch closes operating relay 3 whereby the potential is disconnected and the circuit of the impulse counter 4 is broken. The switch remains closed until the charge on the condenser formed by the two electrodes leaks away, this leakage is controlled by the radiation intensity and each time the switch releases an impulse is recorded by the counter 4 and the condenser is recharged from the H.T. supply. In a third arrangement (Fig. 3 not shown) the ionization chamber is mounted separately from the switch with its electrodes connected to those of the switch.

[Also in Group XXVI] In a pump for liquids or finely divided solids or a blower or fan for air or other gases, the impeller comprises a cylinder 4 made of expanded metal sheet secured within annular grooves formed in a support disc and a reinforcing ring 6, as by adhesive bonding, brazing or soldering. The two ends of the sheet are butted together and may be fastened together by adhesive bonding, brazing, soldering or welding or left unfastened. The strands of the expanded metal, being tilted at an angle to the surface of the material, act as impeller blades. Instead of being parallel to the impeller axis, the major diagonal of each diamond-shaped aperture of the material may be positioned helically of the cylinder 4 to impart an axial component of flow. In a modification, the expanded metal cylinder is force-fitted on to a flanged support disc so that the latter lies in the middle of the cylinder. The edge of the cylinder is turned inwardly to reinforce it. The impeller may be of conical or part-spherical instead of cylindrical form. The expanded metal may be coated with a plastics composition.
