Title: Improvements in and relating to electric impedances of variable value
Inventor: HALLAS LISTER
IPC: G01R1/20
Filed: 1957-07-26
Abstract: 890,945. Networks of resistances, or capacitances, or inductances. TELEPHONE CABLES Ltd. July 25, 1958 [July 26, 1957], No. 23755/57. Class 40(8). A variable impedance comprises a number of separate equal-value impedances and an impedance of N times that value, the impedances being associated with N two-way switches in such a manner that by operating the switches one at a time in one sense and thereafter one at a time in the opposite sense the total impedance in circuit is varied in 2N-1 equal steps from a minimum to a maximum and then from the maximum to the minimum value in a single final step. The variable capacitance of Fig. I comprises four capacitors Cl of unit value and a five-unit capacitor C5 associated with five two-way switches CA4-CD4 and CE5. In the condition shown, there is no capacitance between terminals x and y. If the contacts of switches CA4-CD4 are closed one at a time in any order upon terminals a, the capacitance between the terminals x,y increases by unit steps to four units. Actuation of switch CE5 brings the five-unit capacitor C5 into circuit and short-circuits the unit capacitors C1. The total capacitance may now be increased from 5 to 9 by returning the switches CA4-CD4 to their initial condition. When the remaining switch CE5 is returned to its initial condition, the value of the capacitance between terminals x and y is again zero. A further section of the circuit comprises four ten-unit capacitors C10 and a fifty-unit capacitor C50 associated with five switches CF4-CI4 and CJ5. Each switching operation of the second section is arranged to occur as the switch CE5 is returned to its initial condition, on the completion of each switching cycle of the first section. By this means the total capacitance is increased in unit steps to 99. A further increase of one unit is obtained by closing switch CK4 which brings the 100-unit capacitor C100 into circuit. Thereafter, a further switching cycle of the second section brings the total capacitance to 199. The variable resistance of Fig. 3 comprises two sections connected in series between terminals x,y, each section comprising two series of four resistors of equal value and a further resistor of five times that value. In addition, a 100-unit capacitor is connected in series with the two sections. The numbers associated with the resistors on the Figure indicate the resistance values. The switches are operated in the same manner as those in the variable capacitance of Fig. 3 to obtain a resistance increasing in unit steps to 199 units. Inductors may replace resistors.

Title: Process for improving or re-conditioning wools, soiled fabrics or other fibrous materials
IPC: D01C3/00
Filed: 1924-09-08
Abstract: Wools, or other fibrous materials in bulk, or in the form of slivers, threads, soiled fabrics, &c., and particularly wools which have been subjected to a washing or chemical treatment and have thereby been deprived of suint, are treated with concentrated suint at about 4 DEG B<\>ae obtained from raw wools, the treatment in the case of wool in bulk being accompanied by purification of the suint for re-use.  The treatment is stated to impart softness, strength, elasticity, and suppleness to the material by re-adsorption from the suint of any principles it may lack.  The suint also acts as a detergent and washes the wool.  The suint removed from the treated material is purified by a two-stage centrifuge, preceded, if desired, by fibre retaining means, and air may be introduced into the treating vats all in the manner described in Specification 221,521.  Further to increase the action of the suint, the volume of the vats is reduced as much as possible; and to decrease the volume of liquor to be purified, the liquor to be centrifuged consists of the flushings from the false bottoms of the vats, and of the liquors expressed by the squeezers.  Anti-putrefactive agents may be added to the treating baths as described in Specification 240,499.  The material to be treated may be passed through an old soap bath or a solution of carbonate of soda prior to the suint treatment, the material being, in some cases, washed after the suint treatment in one or more soap baths.

Title: Apparatus for measuring the output of fluids
IPC: G01F15/07
Filed: 1945-09-18
Abstract: 622,640. Meters; recording-apparatus. SOC. ANON. DE DISTRIBUTION DU GAZ (DISTRIGAZ). Sept. 18, 1945, No. 24105. Convention date, Oct. 11, 1940. [Classes 106 (i) and 106 (iv)] A gas or liquid meter drives shafts 26, 32 through a pin-wheel 24, the pins of which break in the event of a defect to protect the other mechanism. The shaft 32 drives a recorder plate 68 from which is printed the units and tens of cubic metres of gas consumed in an hour, the plate being connected by gearing 69, 70, 71, 72, Fig. 7, with a hundreds and thousands recorder plate 76, which carries a drum 73 round which passes a wire 74 connected to a spring-influenced carriage 91 bearing a stylus 98 tracing on a clock-driven strip 104, and a pointer 97 indicating against a scale 96. A manually adjusted stylus 99 traces the consumption to be aimed at in each hour. At the end of an hour, a pin 109<SP>1</SP> of a clock-driven disc 109, Fig. 13, releases a spring-pressed hammer 111, 113 which rocks a lever 120, 122 clockwise to release an arbor 125 and a cam 127, whereby the gear train 129, 130, 130<SP>1</SP>, 40 is freed and turns with a sleeve 33 coupled to the shaft 26, Fig. 1, through the action of a friction clutch 35. The sleeve 33 carries cams 49, 56, 61, 77, the last operating a hammer 83 to print the hour's consumption from the plates 68, 76. Immediately before this, the cam 49 rocks a lever 50, Fig. 5, to throw out of gear the wheels 45, 47 in the drive to the recorder plates, the wheel 45 being at once held by a detent 52. A gear 44 connected by a coil spring to the gear 45 continues, however, to be driven from the meter by gear 42, and when, after recording, the gear 45 re-engages the gear 47, the amount of fluid consumed during the interval is registered on the plates 68, 76 immediately. The cam 56 restores the recorder plate 68 to zero through a heart cam (Fig. 6, not shown), the shaft 48 of the plate 68 being accurately zeroized by a notched plate 53 and check pulley 54, Fig. 5. At the same time, the cam 61, Fig. 7, rocks a lever 66 to disengage the drive from the plate 68 to the plate 76, which is restored to zero under the spring action on the carriage 91, a stop button b contacting an abutment 76<SP>1</SP>. If the consumption in any period is excessive, a pin a on the plate 76 rocks a lever 115, Figs. 7, 13, which releases the lever 120, 122 to initiate a printing and zeroizing operation. The clockwork is rewound from the shaft 128 at each printing operation and can drive the record strip even if the meter should be inactive for a time.

Class 9(2) A torpedo having an electroacoustic transducer 14 suspended in a liquid-filled chamber 13 closed by a flexible diaphragm 15 is provided with pressureresponsive means 12 for controlling the depth at which the torpedo operates, changes in hydrostatic pressure on the diaphragm being transmitted through the liquid filling to the control means. A mixture of silicone fluids may fill the chamber 13 which communicates through a tube 38 with a bellows 37 attached to a plate 30 carried by an actuator 28, so that the actuator rocks in response to pressure changes in the bellows. The actuator 28 has pin-and-slot connection to a rocker arm 25 on which mercury switches 24, 27 are mounted, so that when the arm rotates. clockwise switch 24 is closed and a solenoid 20 is energized through a relay 22. Rotation in the opposite sense closes switch 27 and energization of solenoid 21. Each solenoid is connected to a pivoted elevator 19 mounted on either side of the tail 11, to control the depth movement of the torpedo in response to movement of the arm 25. A tension spring 32 attached to the plate 30 and to a nut 33 on a screw 34 is used to bias the plate 30, by means of a reversible motor 41 in driving connection with the screw. Motor 41 is intermittently used to turn the screw 34 in the direction corresponding to ascent of the torpedo, until the torpedo reaches predetermined ceiling in its search for a target. The motor is then reversed to cause the torpedo to descend.

Title: Polymerization process
Inventor: MACPHERSON WILLIAM GEORGE
IPC: C08F2/22
Filed: 1960-07-13
Abstract: A process for preparing water-insoluble copolymers in aqueous dispersion, wherein an aqueous phase consisting of all the water to be used, a free radical polymerization catalyst, a hydrophilic dispersant and a mixture of ethylenically unsaturated copolymerizable monomers is subjected to elevated temperatures in a closed vessel, is characterized in that the aqueous phase is heated to the polymerization temperature and that initially not more than 20% of the intended total weight of the monomers, containing a higher concentration of the faster polymerizing monomer than the concentration in the final copolymer, is added and the dispersion is heated for a time such that the operating falls to a value at least 70,207 g./cm.2 below the saturation pressure and the rate of addition of the remainder of the monomers is controlled so that the operating pressure remains substantially constant and at least 70,307 g./cm.2 below the saturation pressure, the monomer ratio in the remainder of the monomers being the same as in the final copolymer product. Copolymers specified are those of vinyl and vinylidene chlorides with one another or with vinyl acetate, alkyl acrylates or acrylonitrile. Hydrophilic dispersants specified are water-soluble alkyl and hydroxyalkyl-alkyl cellulose ethers, bentonite clays for suspension processes, alkyl aryl sulphonates and sodium alkyl sulphates for emulsion processes.  In an embodiment of the invention both a suspending agent and an emulsifying agent are used, and when the proportions are 0,05 to 0,2% of the former and 0,01 to 0,3% of the latter polymers which readily absorb plasticizers by mere soaking are obtained. Catalysts specified are hydrogen, benzoyl and lauroyl peroxides and potassium persulphate.  Addition of the main monomer charge may be continuous or incremental.  Examples describe the copolymerization of (1) vinyl and vinylidene chlorides in the presence of hydroxypropyl methyl cellulose, sodium lauryl sulphate and lauroyl peroxide; (2) and (3) vinylidene chloride and acrylonitrile in the presence of hydrogen peroxide and ferric nitrate and sodium sulphosuccinate, the dihexyl ester of sodium sulpho-succinic acid or hydroxypropyl methyl cellulose.  The process produces copolymers of homogeneous composition from monomers of differing reactivity.

Title: Improvements in or relating to tools for stripping coverings from the ends of covered cables, conductors and the like
Inventor: OWEN JAMES
IPC: H02G1/12
Filed: 1949-09-23
Abstract: 666,059. Cable stripping tool. ELECTRIC & MUSICAL INDUSTRIES, Ltd. Sept. 13, 1950 [Sept. 23, 1949], No. 24424/49. Class 36. A tool for stripping the ends of a length of covered wire comprises cutting-devices to cut through the covering at suitably-spaced points and means for causing relative movement between the wire and the cutting-devices so that the ends of the wire are withdrawn from the severed end sections of the covering. The wire to be stripped is fed from its bobbin through notches in blades 22, 6 and 5, mounted on a baseplate 7, so that the end of the wire abuts a stop 19. A block 1 carrying blade 21 and notched blades 3, 2, co-operating with blades 22, 6 and 5, respectively, is caused to descend so that the wire is severed by blade 22. Blades 3, 6 and 2, 5 cut through the insulating covering of the wire adjacent each end, a stop being provided in the path of block 1 to ensure that these two pairs of blades do not damage the wire. A horizontal arm 14 carried by lever 16 pivoted at 17 is then drawn forward so that a hook 15 thereon engages with the centre portion of the wire, drawing it forward into a loop between rollers 11, 12. The ends of the wire are pulled through the apertures between blades 3, 6 and 2, 5, the severed insulation being retained by the blades. The tool may be modified to strip one end only of a length of wire by replacing one of the pairs of notched blades by a clamping device. The blades 22, 22 may also be omitted. The tool may be adapted for operation by a foot pedal, or may be rendered completely automatic, and the blades may be heated.
