Title: Digital encoding transducer
IPC: H01H19/00
Filed: 1971-07-02
Abstract: 1355557 Selective signalling HOUSTON NATURAL GAS CORP 2 July 1971 [22 Oct 1970] 31035/71 Heading G4H A digital encoding transducer which measures the angular position of rotatable geared shafts 14, Fig. 2, representing successive decades of a register (e.g. for a gas meter), incorporates means for detecting and correcting positional errors in the decade readings. Attached to each shaft are brushes 62-72 which coact with a switch pattern A-E, G (ground) to generate a five bit code (for each decade in turn) which represents thirty angular positions 0<SP>1</SP>-9<SP>11</SP>. The segments are arranged so that the change in code between adjacent positions is one bit and so that each brush contacts only one segment at a time. The positions include ten numbered positions 0-9 each having two interface positions (e.g. 0<SP>1</SP>, 0<SP>11</SP>) which are angularly less than 10% thereof but greater than the positional errors. Such errors may be caused when a brush either leads or lags with respect to its correct position (Fig. 6): as the brushes 84 read off the values 0-9 from a decade, corresponding brushes 86 on the next higher decade move across a numbered position N<SP>H</SP> and its interface positions N<SP>H1</SP>, N<SP>H11</SP>. Since these latter are less than 10% of N<SP>H</SP>, a misplaced brush 86 will only give rise to an incorrect reading when brush 84 is traversing positions 0<SP>1</SP>, 0, 0<SP>11</SP> and 9<SP>1</SP>, 9, 9<SP>11</SP> (the incorrect reading being the result of a lagging and a leading brush respectively). To remove such an error the signals are decoded and stored in an appropriate memory, and the uncorrected higher order signals ..., N<SP>H1</SP>, N<SP>H</SP>, N<SP>H11</SP>, ... are fed to the circuit of Fig. 4, which includes NOR gates 147 &c., and NOR gates 149 &c. which are enabled by a signal 126, 127 or 128, according as the position read by the lower decade is in the range 1-8 (when no correction is necessary) or is 0 or 9. The resulting signal from NOR gate 140 &c. then represents the higher decade signal corrected in the light of the particular lower decade -signal which obtains, so that the positional errors are eliminated from one decade to the next. The correction procedure operates from the lowest to the highest decade, and a special procedure is built in (Fig. 4A, not shown) for processing the lowest decade signal, which is always assumed to be correct.

Title: Re-Preparable Negative Master Plates for Making Perforated Foils by Electro-Deposition.
Inventor: FUETTERER BODO
IPC: B26B19/38
Filed: 1967-07-05
Abstract: 1,189,718. Dry shavers. GILLETTE CO. 5 July, 1967 [6 July, 1966], No. 31037/67. Heading B4B. [Also in Division C7] A foil 4 having holes therethrough, e.g. as used for screens and shearing foils of electric shavers, is made by forming electrically insulated areas 2 on the surface of a metal base-plate 1 in the areas where it is desired to have the holes, electroplating the rest of the base-plate to provide a metal coating 3 and passivating the metal coating 3 so as to enable the foil 4, which is subsequently electrodeposited, to be stripped from the metal 3. The passivation may be by treatment with bichromate solution. The base-plate 1 with insulation 2 and metal coating 3 serves as a negative for making the foil and can be reprepared by removing the metal coating 3 and insulation and repeating the process. To enable removal of the metal coating 3 without attaching the metal baseplate 1, the coating 3 is of a metal such as Sn or Zn which can be dissolved in an alkaline bath and the base-plate 1 is of metal such as steel, Ni or brass which is resistant to an alkaline bath. Fig. 2 (not shown), illustrates an embodiment where the insulating material is embedded in etched shallow holes in the base-plate.

Title: Improvements in or relating to arrangements for generating electric pulses
IPC: H04J3/00
Filed: 1945-11-21
Abstract: 596,699. Pulse-generating circuits. STANDARD TELEPHONES & CABLES, Ltd., EARP, C. W., and LEVY, M. M. Nov. 2 1., 1945, No. 31332. [Class 40 (v)] A series of trigger circuits operate in succession to generate a series of trains of rectangular pulses which have the trailing edges of one train coinciding with the leading edges of the next train. Starting pulses of period T are applied to the first trigger circuit which produces secondary starting pulses for the next stage, and so on throughout the series. Terminating pulses with period t=T/n are applied to all the circuits simultaneously in order to restore each circuit in turn to the quiescent state. In Fig. 1 oscillations at peniod tare limited and differentiated to produce a train of positive terminating pulses for application to n similar pulse generators via conductor 6. The pulses are also frequency divided by ratio n to produce starting pulses for the first generator, which may be a biassed multivibrator, with terminating pulses applied to the grid of the normally conducting valve so that they have no effect in the quiescent state. Negative starting pulses over-ride the terminating pulses to operate the trigger circuit concerned until the next terminating pulse restores quiescent conditions and initiates a starting pulse for the next generator. Pulse widths may vary for different trains in multiples of t when less than n generators are employed. Miller type generators may be employed with the terminating pulses applied to the cathode to control the flyback, while Fig. 7 shows an alternative generator which may be used in the modified system in Fig. 8. Grid controlled valves 88, 89 are normally extinguished and a positive starting pulse at b renders valve 88 conducting to prepare valve 89 for conduction at the next terminating pulse by developing the anode supply across high resistor 92. When valve 89 conducts, capacitor 91 is discharged rapidly through low resistor 93 to extinguish both valves, producing a rectangular output at terminal 11 and a secondary starting pulse for the next stage at conductor c. In Fig. 8, oscillator 1 has a period 2t and the limited waveforms are applied directly to the odd numbered generators and through a phase inverter 95 to the even numbered generators. as terminating pulses. The leading edges of each pulse train are interleaved so that the generators again operate in succession in response to a starting pulse obtained from the limited waveform by differentiation and n/2 frequency division.

Title: Polymer dispersions
Inventor: OSMOND DESMOND WILFRED JOHN
IPC: C08G63/06
Filed: 1964-08-04
Abstract: Dispersions of polymer particles in an organic liquid in which the polymer is insoluble are prepared by polymerizing at least one ethylenically unsaturated monomer in the organic liquid which contains a preformed dispersion stabilizer, the latter being the product of condensation reaction between (a) at least one component which has a molecular weight of 500-5000, is solvatable by the organic liquid and contains a group capable of condensation reaction; and (b) another component which has a molecular weight of at least 250, is of different polarity from the solvatable component, is relatively non-solvatable in the organic liquid, and contains a group capable of condensation reaction with component (a), the total weight ratio of component (a) to component (b) in the stabilizer being from 0.5:1 to 5:1. The stabilizer may contain, in the molecule, more than one unit of component (a).  The stabilizer may be made by a condensation reaction involving the production of ester, ether, amide or urethane links.  In examples using azodiisobutyronitrile as initiator (1) methyl methacrylate and methacrylic acid are polymerized in petroleum (b.p. 60-80 DEG  C.) and white spirit; (2) methyl methacrylate is polymerized in a mixed aliphatic/aromatic hydrocarbon solvent; (3) methyl methacrylate is polymerized in petroleum (b.p. approximately 80 DEG  C.); (4) methyl methacrylate is polymerized in petrol/ white spirit; (5) vinyl acetate is polymerized in aliphatic hydrocarbon solvent; (6) styrene is polymerized in ethanol.  The dispersion stabilizers in the examples are obtained by (a) reacting 12-hydroxystearic acid trimer with an epoxy resin (obtained from diphenylolpropane and epichlorhydrin); (b) reacting poly-12-hydroxystearic acid with an epoxy resin; (c) reacting adipic acid, glycerol and stearic acid to form a polyester and then reacting the latter with an epoxy resin; (d) reacting a methyl methacrylate/glycidyl methacrylate copolymer with poly-12-hydroxystearic acid; (e) treating poly-12-hydroxystearic acid with thionyl chloride and reacting the product with a polyester obtained from phthalic anhydride and ethylene glycol; (f) copolymerizing styrene and acrylic acid and reacting the product with methoxy terminated polyethylene glycol; (6) hydrolysing a telomer (obtained by polymerizing styrene with benzoyl peroxide in the presence of carbon tetrachloride) with alcoholic KOH, converting to acid form by treatment with mineral acid and reacting the product with epoxy resin.
