Title: Magneto-optical analogue computation
Inventor: PEARSON RONALD FERGUSON
IPC: G06E3/00
Filed: 1968-07-04
Abstract: 1,221,086. Light insulators. MULLARD Ltd. 4 July, 1968, No. 31917/68. Heading H4F. [Also in Divisions G1 and G4] Adding and multiplying circuits utilize rotation of plane polarization of electromagnetic radiation by an element of Yttrium Iron Garnet subjected to a magnetic field and exhibiting Faraday effect. A source S of infra-red light (Fig. 1) is focused on a polarizer P from which beams traverse Faraday elements MO 1 , MO 2  to analyser A oriented 45 degrees to the polarizer from which emergent beams fall on photo-electric detectors D 1 , D 2  series connected to T out . Attenuation may be introduced by graduating the excitation kI 0  of the detectors or by inserting a resistance network inT out . It is shown that if electromagnet coils C 1 , C 2  of the elements are excited by currents i 1 ,i 2 , T out  is a function of the sum (or difference) of i 1 , i 2  for small rotations of polarization. A lens may focus both beams on a single detector (Fig. 1a not shown) and the beam may traverse two Faraday elements in tandem to a single detector (Fig. 2, not shown). The analyser and polarizer may be oriented at 90 degrees and a further polarizer oriented at 45 degrees thereto may be inserted between the elements, introducing both a product and a summation term; thus multiplying for inputs of identical frequency or for inputs of differing frequency with filtration of sum and difference terms (Fig. 3, not shown). The intermediate polarizer may be replaced by a polarizer in each beam whose planes are disposed at + 45 degrees to that of the initial polarizer in opposed senses, and lenses focus the source up on the initial polarizer and the analyser on the detector wherein the output represents the product of the inputs (Fig. 4, not shown). In a further modification (Fig. 5) the source is focused by lens 51 on polarizer 52 whose emanent light traverses element MO 1  controlled by energization of coil C 1 ; one emanent beam passing through polarizer 53 oriented at + 45 degrees to 52 and the other passing directly to element MO 2  controlled by energization of coil C 2 . The letter beam traverses polarizer 54 disposed + 45 degrees to 52 and the former beam passes direct to analyser A disposed 90 degrees to 52; the emergent beams falling on photo-electric detectors D 1 , D 2  whose outputs are series subtracted. Then the resultant is proportional to the product of i 1 , i 2  energizing C 1 , C 2 .

Title: Automatic size control means for bore-abrading tools
Inventor: WAGSTAFF GEORGE FREDERICK
IPC: B24B33/06
Filed: 1952-12-20
Abstract: 732,390. Gauges for honing machines &c. DELAPENA & SON, Ltd. Dec. 15, 1953 [Dec. 20, 1952], No. 32342/52. Class 60. Automatic size control means for an abrading tool, such as a hone, having a head which is rotated 'and reciprocated within a bore 13 comprises two spaced gauging members 16 having parallel surfaces 16b, the gauging members being mounted outside and near one end of the bore so as to be movable towards and away from each other, and an element 44 carried by the abrading head for rotation and reciprocation therewith in such manner that a portion of the element follows the bore in a rotary sense and progressively moves the members 16 away from each other as a measure of the bore diameter so that the abrading operation may be stopped when a predetermined size is reached. The members 16 are mounted in guide channels 15 fitted with light bowed springs 51 to provide a slight frictional resistance to movement of the members 16. Outward movement of these members by the member 44 causes levers 19, 20 to be progressively tilted about fulcra 21, 22 until two washers 25 connected to the levers by an insulated mounting engage a gauge bar 32 'and thus complete a circuit from a battery 35 to a signal device 36. The length of this gauge bar is adjusted by means of a threaded portion 53 so that the circuit is closed when the surfaces 16b are separated by an amount corresponding to the required bore size, the surfaces being adjusted prior to honing by rotating screws 48 until the surfaces engage the ends of an internal micrometer. Graduations 52 permit the members 16 to be set approximately symmetrically. The screws 48 are mounted in bushes 49 provided with feed levers 49a which are rotated through an angle of 90 degrees after the adjustment of the screws 48 to advance the members 16 towards each other by a predetermined amount and thus break the electric circuit in readiness for a honing operation. Reverse rotation of the bushes retracts the screws 48 so that they will not impede the movement of the members 16. Once the latter have been set for a bore of a particular size, they may be easily re-set for successive bores of the same size by rotation of the levers 49a to a predetermined position. The member 44, which has a radiused boreengaging surface and chamfered ends, is urged outwardly by springs 46 and.centrifugal force.

Title: Titration system
IPC: G01N31/16
Filed: 1972-07-11
Abstract: 1423997 Automatic titration apparatus RADIOMETER AS 10 July 1973 [11 July 1972] 32366/72 Heading GIN  In an automatic titration system in which an electrical signal is produced dependent upon changes in a parameter of the solution to be tested the changes in the electrical signal as the titration proceeds are nulled by a signal from a compensating circuit. In the titration of an acid in vessel 17 with a base supplied by automatic burette 22 the controller 15 is manually set at a set point voltage a little lower than the initial output voltage of pH meter 12 connected to measuring and reference electrodes 18, 19. Coil 40 of relay 16 under the control of controller 15 is thus deenergized and contact 39 closed and 38 opened whereby analogue integrator 27 starts to integrate the negative voltage from cell 30. The integrator output is fed to servomotor 34 to move the pen 35 of the recorder 14 to the right and also to the input of the controller 15. Since the integrated voltage is of opposite sign to the pH meter 12 output and slowly increasing the net input to the controller 15 decreases. When it becomes lower than the set point value relay coil 40 is energized and the contacts 38, 39 changed over to the position shown whereby the integrating process is interrupted and the pen 35 stopped and the power supply circuit to motor 26 energized to cause titrant to be fed to the vessel 17 and move paper 37 along. The resultant increase in pH provides an increasing positive input voltage to controller 15 and when the total input voltage exceeds the set point value coil 40 is again de-energized, the analog integration proceeds and feeding of the titrant stopped. In this manner a graph may be plotted stepwise. The integrator 13 may be replaced by an arrangement Fig. 2 (not shown) in which a pulse generator is connected to a counter via contact 39 and the output of the counter is connected to a digital/analogue converter. The output voltage of the converter is supplied,to the input of the controller. The titrant may be added by a volumetric method, as described, or a coulometric method, and the parameter measured by a potentiometric, conductometric, photometric or an amperometric method.

Abstract: 624,720. Producing patterns on fabrics. BRITISH CELANESE, Ltd. Oct. 31, 1946, No. 32374. Convention date, Oct. 31, 1945. [Class 42 (i)] Fabrics made of or containing a substantial proportion of thermoplastic yarns are given a randomly quilted effect by bringing them into contact with a heated, unpatterned surface, while untensioned and unconstrained until the thermoplastic yarns are softened sufficiently to cause local buckling of the fabrics which are thereafter removed from the surface. The fabric 8 is paid-off from a roll 5 by a positivelydriven rubber covered roll 9, in frictional contact therewith, and falls on a heated surface 14 ; it is withdrawn by a take-off roll 17 which is driven at a speed in such ratio to that of the roll 9 that the fabric 8 is under substantially no tension during treatment. The fabric may then fall upon a table 22 where it cools. The surface 14 may be metal or ceramic, and may be heated by electrical resistance coils. For cellulose acetate fabrics a temperature of 250 to 280‹ C. is suitable, the fabric remaining in contact with the surface from 1 to 5 seconds. The surface 14 is preferably lubricated with a heat-resistant lubricant such as a polymeric organic silicone, e.g. polymeric methyl silicone having the consistency of a grease. The thermoplastic constituent of the fabric may be a cellulose ester, mixed ester or ether, a synthetic linear polyamide condensation product, e.g. polyhexamethylene adipamide, a polymeric vinyl compound or co-polymer, or a polymerized methacrylic acid compound. The fabric may contain non-thermoplastic yarn having a basis of silk, cotton, wool, flax, regenerated cellulose or the like.

Title: Pneumatic vehicle-brake apparatus
IPC: B60T8/32
Filed: 1949-12-19
Abstract: 676,317. Fluid-pressure brakes. REGIE AUTONOME DES TRANSPORTS PARISIENS. Dec. 19, 1949 [Dec. 23, 1948], No: 32458/49. Class 103 (i). A control mechanism for use with vehicle fluid pressure brake systems, such as the Westing- house system, has the object of limiting the deceleration of a vehicle to a predetermined value that should safely prevent the initiation of any wheel slip, but does not correct wheel slip if this begins. In a brake system in. cluding a brake pipe 1, reservoir 6, triple valve 5 and brake cylinder 4, a pipe 7 led off the brake cylinder leads to either side of a piston 10 controlling by a valve 11 a port 12 to atmosphere. A further pipe 13 from the chamber 25 to one side of the piston 10 leads to a relief valve 23 past a valve 14<SP>1</SP> electromagnetically controlled by a circuit governed by a pendulumtype inertia switch, as shown of the mercury tube type, which operates at the predetermined value of deceleration. If this deceleration value is exceeded pressure is released from the chamber to the left of the piston 10 so that that to the right moves the piston and opens the valve 11 to release the brake cylinder pressure. The brake cylinder pressure is prevented from falling below a certain minimum value by the valve 23. In the arrangement shown in Fig. 2 of the invention applied to a train of vehicles, for instance three coupled coaches A, B and C, there are two mercury pendulum switches 28, 28<SP>1</SP>, only one of which is operative to control all the brakes of the train according to the direction of travel. Specification 447,993 is referred to.

Abstract: 679,933. Twisting yarns. UNION DES FABRIQUES BELGES DE TEXTILES ARTIFICIELS FABELTA SOC. ANON. Dec. 19, 1949 [Dec. 18, 1948], No. 32521/49. Class 120(ii) In a doubling or cabling device in which the primary twist of individual yarns is substantially unaltered, each yarn is guided between a fixed point on a rotary spindle and a fixed doubling point on the spindle axis, and passes through an intermediate moveable guide carried by the spindle in such a way that twist imparted during the movement of a yarn from its supply package to the intermediate guide is substantially cancelled out by that imparted during the movement from the guide to the doubling point, and a yarn from one package is ballooned by the rotating spindle about another package supported by the spindle, the ballooning being limited owing to a continuous rigid surface integral with the spindle and placed outside of and guiding the yarn, one package of elementary yarn being, placed outside the spindle on a support which is independent of the. spindle. As shown,. one yarn supply package 1 is mounted on bearings 4 on a rotary spindle 3 and is prevented from rotating by a weight 5. A bowl 6 fixed to spindle 3 surrounds package 1 and is provided with yarn guides 10, 20. Yarn 7 is drawn from package 1 via a flyer guide 8 from which it passes through guide 10 to a fixed guide 11. The other supply package 12 is fixedly mounted on a support 13. Yarn 14 is drawn from package 12 via a flyer guide 15 from which it passes through spindle 3, out through an opening 18 therein, through an opening 19 in bowl 6, along the inside of bowl 6 (to limit ballooning), through guide 20, and thence to guide 11. With each yarn, the twist inserted between the package and the guide 10 or 20 is removed as the yarn passes to guide 11, except for the slight twist imparted by flyer 8 or 15, so that after guide 11 the yarns porceed with substantially their original twist, and are plied together with a ply twist dependent on the speed of rotation of spindle 3 and the speed of wind on to a take-up, package 21.

Convention date, May 5. Void [Published under Sect. 91 of the Acts]. [Classes 18 and 94 (i).] Packets are made and filled with articles or groups of cigarettes. One form of machine is shown in plan in Fig. 2. A blank Z is fed in front of a folding box 1 after adhesive has been applied at the appropriate parts. A former 3 is actuated by gearing 4 .. 8 to force the blank into the folding box, in which known folding devices 9, 10 are disposed so as to result in the formation of a packet as shown in Fig. 9. The continued movement of the former carries the packet into one of a series of holders 11<1> on a chain 11, actuated to move intermittently. The former 3 recedes, the packet being retained in the holder by known means, and two intermittent movements bring it to a filling station x, Figs. 2 and 4. At this point, a ram 15 forces a group G of cigarettes from a hopper 14 through a funnel 12 into the packet. The funnel is actuated by a cam 21 and spring 22 to move into and out of the mouth of the packet at the appropriate times. After two more intermittent movements, the packet arrives at a folding station y, where folders 29 are actuated by a wedge 25 to turn down the end tucks. At the next station z, a folder 30 descends and turns down the upper broad flap, and, during the subsequent travel, a plate 36 turns up the last flap. A ram 37 thrusts the completed packet into a channel 38, from which a member 39 moves it on to a delivery belt 40. In a modified form of apparatus, the packet, having been formed in substantially the same manner, is thrust into a pocket in a rotating turret, from which it is later stripped on to a filling table and transferred to a belt for end closing.
