Patent GB-451165-A (GB)
Title: Improvements in coin freed mechanism more especially designed for use with electricity meters
IPC: G07F15/04
Filed: 1935-10-10
Abstract: 451,165. Prepayment mechanism for meters. LANDIS & GYR AKT.-GES., 1, Hofstrasse, Zug, Switzerland. Oct. 10, 1935, No. 27942. Convention date, Oct. 17, 1934. [Class 27] Coin action, mechanical-connection.-In a prepayment meter, the usual setting handle is replaced by an auxiliary source of power, e.g. a spring or electric motor, the inserted coin forming a connection between the source of power and the quantity mechanism. As shown, an electric motor 5 drives a rotary coin pocket 2 so that an inserted coin, during a half-revolution of the pocket, engages and steps forward a star-wheel 22 connected with a sun-wheel 23 of the quantity mechanism. The coin pocket is connected through gearing 6 and a slipping friction coupling with a helical spring 8 which is thereby maintained under tension. This spring 8 tends to rotate a shaft 7 to disengage the supply contacts 18, 19, but is prevented from doing so, until prepayment is exhausted, by engagement of an arm 9 on the shaft with an escapement shaft 12. When prepayment is exhausted, an arm 28 on the differentially operated shaft 25 of the quantity mechanism engages an arm 16 on the shaft 12 and rotates it to bring a slot 10 opposite the arm 9 which is thus released and rotates through half a revolution under the action of the spring 7, when it is again held by engagement with a lower part of the shaft 12 in the region of a second slot 11 arranged in staggered relation to the upper slot 10. When a further coin is inserted, the arm 28 disengages the arm 16 on the shaft 12 which is then returned to its original position by a spring 14 ; the arm 9 is thereby released by the slot 11, and is moved through a further half-revolution to its original position adjacent the upper slot 10 by the spring 7, so that the contacts 19 are again closed. The motor 5 may run continuously, or be switched on for a short period when a coin is inserted. In the modified construction of Fig. 2 (not shown), the electric motor 5 also serves as a basic charge collecting device. The motor drives one half of a divided and diametrically slotted coin drum, the other half being connected to the quantity mechanism, and the two halves being coupled by the coin. Mechanism for prepaying basic charges.-The mechanism by which the constant speed motor 5 operates to collect a basic charge in the modified construction of Fig. 2 is as described in Specification 424,539. The motor 5 may be controlled by a clock-operated switch which shuts off the motor during times of low consumption, adjustment of the clock serving also to vary the basic charge rate. Alternatively, the drive of the motor 5 to the basic charge mechanism may be intermittently interrupted under the control of an adjustable clock mechanism.

Patent GB-828723-A (GB)
Title: Method of making solid disproportionated silicon monoxide
IPC: C08K3/34
Filed: 1956-09-13
Abstract: Solid disproportionated silicon monoxide is condensed from gaseous silicon monoxide in the presence of an inert gas containing a hydrogen-furnishing gas.  The product may contain ca. 31.8% Si and 68.2% SiO2.  The inert gas may be carbon monoxide, nitrogen, argon, helium, or neon, or a mixture of two or more of said gases.  The hydrogen-furnishing gas may be hydrogen itself, or methane, ethane, propane, butane, or another paraffin hydrocarbon which is capable of cracking to produce hydrogen under the conditions of condensation. The ratio of gaseous silicon monoxide to the mixture of inert gas and hydrogen-furnishing gas may be 1:3-15, preferably 1:8.  One to five parts of hydrogen may be used per 1-100 parts of inert gas.  40 Cu. ft/min. of nitrogen containing 0.03 part of hydrogen may be used in the condensation of 10-15 lb/hr. of silicon monoxide.  The hydrogen-furnishing gas may be introduced into a mixture of the inert gas and the silicon monoxide gas or into either constituent before admixture.  The hydrogen-furnishing gas and inert gas may be mixed relatively slowly with the silicon monoxide gas without causing substantial turbulence, when a fibrous product having a surface area of 60-200 sq. m/gm. and a ratio of diameter to length of the individual fibres of 1:10-50 may be produced.  The inert gas and hydrogen-furnishing gas may form a column or cone about a stream of the silicon monoxide gas.  Turbulent mixing, with the production of a spherical product, may be effected if desired. The silicon monoxide gas may be produced by heating a mixture of silica and carbon, silicon carbide, or silicon, at a temperature of 1500-2000 or higher, in an arc furnace, e.g. provided with Soderburg electrodes, or a resistance furnace.  The silica may be in the form of sand, quartz, or a silicate, and the carbon may be in the form of anthracite, graphite, carbon black, coal, coal coke, or petroleum coke.  The silicon monoxide gas may be produced in a batch or continuous process.  In the former, inert gas must be added to the mixture of silicon monoxide and carbon monoxide produced.  In the latter, inert gas must be added initially but thereafter a portion of the gas remaining after separation of the condensed silicon monoxide may be recycled to the process, hydrogen-furnishing gas being added as necessary.  In the two examples given products having a surface area of 105 and 122 m2/gm. respectively were produced by charging an equimolar mixture of sand pulverized anthracite coal to an arc furnace, the reaction product gas passing from an opening in the top of the furnace to a condensing chamber provided with symmetrically positioned ports about the opening in the furnace top, and thence to a bag collector.  The system was flushed through before reaction with nitrogen at atmospheric pressure.  During reaction gaseous silicon monoxide was evolved at 3.2 cu. ft/min. and mixed with nitrogen containing 0.5% oxygen at 38 cu. ft/min. and hydrogen at 1.3 cu. ft/min.
