Title: Process for reducing chromous and chromic chlorides
IPC: C22B34/32
Filed: 1938-06-15
Abstract: 515,953. Reducing chromium chlorides. GREAT WESTERN ELECTROCHEMICAL CO. June 15, 1938, No. 17857. Convention date, Aug. 3, 1937. Drawings to Specification. [Class 82 (i)] [Also in Group III] A process for the reduction of chromic or chromous chloride and the production of sponge chromium comprises heating the chloride to 775-850‹C. in hydrogen freed from water to such an extent that the partial pressure of the water in the hydrogen at 800 ‹C. is less than 4.5 x 10<-5> atmospheres. The hydrogen may be passed countercurrent to the chloride at such a rate that the hydrogen leaving the reduction zone carries about 4.7 per cent. of hydrochloric acid which is removed by passage over activated carbon. The apparatus may comprise means for freeing the hydrogen from oxygen and drying it by passage over a nickel catalyst and storage over concentrated sulphuric acid, and two alternately used absorbers containing activated carbon, the saturated absorber being regenerated by heating to about 300‹C. and flushing with hydrogen. The reduction may be effected in an electric furnace through which the chromium chloride is passed on trays, the ends of the furnace being sealed by gas locks. In the reduction of chromic chloride, chromous chloride may be obtained as an intermediate step. Specification 300,637, [Class 82 (i)], and U.S.A. Specifications 1,373,038, 1,741,955, and 1,915,243 are referred to.

Abstract: 313,449. Kolster-Brandes, Ltd., (Assignees of Duncan, R. D.). June 11, 1928, [Convention date]. Void [Published under Sect. 91 of the Acts]. Protective arrangements.-In order to exclude from a wired wireless broadcasting or control system interference caused bv a consumer's household electric appliances, e.g. battery charger &c., rejector means comprising inductance and capacity are connected in the consumer's supply mains prior to the service switch. As shown in Fig. 1, an inductance 2 is connected in the supply main 4 and a condenser 3 is connected across the supply 4, 5 on the consumer side of the inductance, the values of inductance and capacity being suitable to eliminate highfrequency signals over a wide range without causing interference with the power supply to the consumer. The arrangement also prevents interference arising within the consumer's premises from reaching the power lines and effecting other consumers. In a three-wire power circuit two units of the type shown in Fig. 1 are used, the inductances being connected in the outers and the condensers between the outers and the midwire.

Abstract: 274,466. Allgemeine Elektricitõts- Ges. July 15, 1926, [Convention date]. Drawings to Specification. Cores; driving arrangements ;motors with unwound iron armatures. - For obtaining silent running of a synchronous electric motor of the type described in Specification 125,766, driving clocks &c., the rotor is provided with thin walls and is weighted with a fixed mass or masses of non-magnetic material in order to determine the weight of the rotor in relation to the length, thickness and elasticity of the shaft in such a manner that the synchronous speed is greater than the critical speed; the critical speed is defined as the speed at which there is resonance between the natural and the induced rates of oscillation of the spindle and is calculated from the formula w= #c/m where w is the critical angular velocity, in the mass of the rotor and c a constant depending on the dimensions and elasticity of the shaft. To ensure that the turning moment applied to the armature shall be a maximum the armature is flanged and the added weight for example, of lead, tin or other non-magnetic substance may be applied by spraying. Further reduction of noise may be obtained by constructing some or all of the gear wheels of a fibrous substance such as paper, vulcanite, wood or leather impregnated with artificial resin.

Abstract: 1,241,251. Two-part couplings. AMP Inc. 23 March, 1970 [10 April, 1969], No. 18443/69. Heading H2E. An electrically insulating housing 1 for an electrical contact such as 30 is formed by extruding plastics material to provide two housing parts 3, 5 integrally hinged at 7 by a reduced cross-section part, the two parts being cl sed about the hinge to embrace at least one Contact in a channel 19 defined by tongues 9. A locking member 13 engages a groove 17 to lock the two parts together. A continuous length of extrusion may be saw-cut at intervals transversely to the extrusion direction to define housings, the housings being connected together by uncut portions below the dotted line shown in ribs 21 for feeding into a machine which assembles the contacts into the housings. A series of contacts 30 joined by portions 36 as shown in Fig. 4 are suitable for connecting to tape cables by crimping arms 46 about a tape conductor and its insulation whilst upstanding tines 48 pierce the insulation and contact the conductor. An upstanding tongue 42 locks the contact in a channel 19 by engaging a slot (25, Fig. 3, not shown) transverse to the channel. A flat tab portion 32 of the contact projects out from the housing to engage sockets mounted in a mating housing. The mating housing (Fig. 7, not shown) has two latching arms projecting in the mating direction with projections at their ends to engage the rear face of the housing 1, grooves in one arm (62) receiving ribs 21. The housing 1 may alternatively accommodate socket contacts and may be suitable for connecting to conductor wires.

Abstract: 1,218,610. Stereophonic receivers; re-inserting carrier; electromechanical resonators; amplitude modulation. MATSUSHITA ELECTRIC INDUSTRIAL CO. Ltd. 18 April, 1968 [18 April, 1967 ; 19 April, 1967], No. 18474/68. Headings H3Q, H3R, H3U and H4L. In a receiver for suppressed-carrier signals the carrier is reinstated by means of a piezoelectric device which resonates in a longitudinal mode and delivers two anti-phase carrier signals when supplied with the suppressed-carrier input. The invention is described in connection with the reinstatement of the 38kHz subcarrier in a stereophonic receiver, which is conventional (Fig. 1, not shown) apart from the piezoelectric device and the switching demodulator. The piezoelectric device (Fig. 2) comprises a thin rectangular ceramic plate having a fundamental longitudinal resonant frequency at 38kHz. Each face of the plate carries three strip electrodes 31-36 extending along the whole length and arranged symmetrically with respect to the longitudinal central axis. The plate is polarized across its thickness and connections are made to the centre points of the electrodes where shown. The E and F inputs are paralleled and comprise the demodulated received signal after removal of any SCA signal and of all or most of the 19 kHz pilot signal. The C input comprises a 38kHz signal obtained by extracting and doubling the pilot signal. The terminal G is earthed and combined outputs are obtained from the U and V terminals comprising the (L + R) and suppressed-carrier modulated (L-R) signals and the subcarrier, the latter being in opposite phases at U and V respectively. These outputs are applied (Fig. 4) to a switching demodulator comprising a bridge of diodes 37 and resistors 38, adjacent pairs of the latter being shunted by capacitors 43, 44. The resistors and capacitors may be omitted, and other types of demodulator can be used. The piezoelectric plate may have five electrodes (Fig. 5, not shown) the E and F signals being fed in parallel to the outermost pair on one side and the inner pair on the other side, and the U and V signals being taken from the other pairs; the C and G connections are on the centre electrodes as in Fig. 2 (Fig. 6, not shown).

By suitably controlling the valves, ingredients can be supplied to all the trunks by some only of the openers, or can be supplied by all openers to some only of the trunks. More ingredients can be dealt with than the number of openers, e.g. by supplying two ingredients X, Y in alternate layers to the feed lattice of one opener AA. The output from the group of feed trunks comprising a blending unit may be divided betwen two or more parallel secondary opening machines ; or two or more such blending units may deliver to a common junction point from which one or more secondary opening machines is or are fed.
