Patent GB-1112168-A (GB)
Title: Bulking yarns,strands and like filamentary material
IPC: D02G1/08
Filed: 1965-12-15
Abstract: A multifilament or monofilament yarn (or two or more such yarns assembled into a strand which is permanently retained or separated into individual yarns after processing) of regenerated cellulose or cellulose esters or ethers or fibre blends thereof, or polyamides, polyesters, polyolefins, polyurethanes, or vinyl polymers or copolymers, is bulked by false-twisting and heat-setting.  From a package (10) yarn (11) passes through eyelets (12 and 13) over a twist-stopping guide (14) and immediately in contact with the curved surface of an internally heated roll (15) which rotates at a peripheral speed equal to or higher than the linear speed of the travelling yarn.  The yarn passes around 240-270 DEG  of the circumference of the roll in a helical path, on to and through a false-twist spindle or tube (16), thence around and through the nip of take-up rolls (18, 19) the speed at which one thereof is driven determining the rate at which the yarn is processed.  The bulked yarn then proceeds with "overfeed" or "underfeed" to mechanism whereby it is wound into a "soft" or "hard" package.  In its passage around the roll, the yarn under tension is rolled from side to side by the effect of friction forces between itself and the roll surface, thus ensuring efficient heat transfer thereto; the false-twist in the yarn varies along with the helical path and the effect of heat-setting such twist causes random distribution of coils, curls or crimps in the individual filaments of the bulked yarn.

Title: Cathode ray oscilloscopes
Inventor: HORNAK TOMAS
IPC: G01R13/34
Filed: 1965-12-20
Abstract: 1,087,210. Cathode-ray oscilloscopes; semiconductor circuits. VYZKUMNY USTAV MATEMATICYKCH STROJU. Dec. 20, 1965 [Dec. 23, 1964], No.53895/65. Headings H3T and H4T. In a sampling oscilloscope for analysing recurrent A.C. waveforms by displaying samples of the latter as (vertical) deflections of a (horizontal) time base, the time base voltage is produced in discrete steps, each of which is synchronized with a sampling pulse but of random amplitude. Referring to Figs. 4, 5 and 6, the random amplitude time base generator comprises a free-running sawtooth wave generator (301) utilizing a PNPN diode (D 1 ), the output being supplied via a gate (302) to a storage circuit (303) including a transistor (Q1) in an emitter follower circuit providing, when the gate is periodically opened, a succession of random amplitude pulses (E R ) for application to the horizontal deflection plates of the oscilloscope tube 107. These pulses are also supplied via an adjustable attenuator (112) to an adding circuit (110) in which they are combined with an adjustable voltage from source (111), the output of the adding circuit being fed as a reference voltage to an amplitude comparison circuit 108 having as second input a sawtooth wave from generator 102 triggered (at 101) by a pulse derived from the recurrent waveform (Ea, Fig. 1, not shown). Amplitude coincidence of the two inputs then results in an output which is utilized to produce sampling pulses in generator (103) for controlling a gate (104) to which the recurrent waveform is supplied via terminal 100. The output samples are then amplified in a wide band amplifier 105 and supplied via a pulse stretcher 106 to the vertical deflection plates of the tube (107) and over lead 201 to a blocking-oscillator pulse generator (304), the output of which controls gate 302. Adjustment of the voltage source (111) determines the time position (with respect to the commencement of a cycle of the recurrent waveform) of the portion to be displayed whilst adjustment of the attenuator (112) determines the width of such portion.

Title: Phosphate-containing compositions
IPC: C01B25/38
Filed: 1964-03-17
Abstract: A detergent composition contains as builder an effervescent composition comprising an amorphous alkali metal condensed phosphate, free alkali metal carbonate and free condensed phosphoric acid, which has an alkali metal to phosphorus molar ratio of from 0.5 to 5 and the ability to sequester in aqueous solution at least 1 g. of calcium per 100 g. of the said composition. The term "alkali metal" includes ammonium. Specified surface active compounds included in the detergent composition are alkali metal salts of organic sulphates or sulphonates, polyethylene oxide condensates with fatty acids, phenols, alcohols, amides or amines and amphoteric compounds such as sodium-N-methyl laurate and N-COCO- beta-amino propionate. In an example detergent tablets are prepared from a builder of the invention, sodium metasilicate, sodium dodecyl benzene sulphonate, sodium sulphate and sodium carboxymethyl cellulose.ALSO:An effervescent composition comprising an amorphous alkali metal condensed phosphate, free alkali metal carbonate and free condensed phosphoric acid has an alkali metal to phosphorus molar ratio of from 0.5 to 5 and the ability to sequester in an aqueous solution at least 1 g. of calcium per 100 g. of said composition. The term "alkali metal" includes ammonium.  The amorphous condensed phosphates used may be those obtained as intermediate products in the process of Specification 1,066,233.  The composition itself may be prepared by applying the first stage of said process, employing as the alkali metal source an alkali metal carbonate and mixing the reactants in such a manner that complete reaction does not occur, e.g. by carrying out the reaction at 20 DEG  to 50 DEG  C. and/or without complete mixing of the reactants.  In one method a stream of a liquid condensed phosphoric acid is slowly added to an agitated bed of the carbonate to produce an encapsulated material comprising free acid coated with a conglomerate mass of condensed phosphate and free carbonate. Materials such as alkali metal or alkaline earth metal hydroxides, sulphates, phosphates, other condensed phosphates, or silicates may be incorporated in the composition either by mixing with the reactants or with the final product.  In examples, effervescent materials are prepared from condensed phosphoric acid and soda ash, which may contain sodium tripolyphosphate with or without sodium sulphate.  The compositions are used as water softeners or in detergent compositions (see Division C5).

Title: A plunger for a solenoid and plunger assembly
IPC: H01F7/12
Filed: 1966-12-08
Abstract: 1,115,589. Solenoid plungers. DETROIT COIL CO. 8 Dec., 1966 [9 Dec., 1965], No. 55102/66. Heading H1P. A plunger for a solenoid assembly comprises a shank and a head having at least one arm extending transversely, and has a shading coil secured to the face of the arm which in use faces the solenoid. The positioning of the shading coil in the plunger instead of in the stator coil is said to reduce damage to the coil produced by the pounding of the plunger against the stator, and increases the efficiency of the assembly since the shading coil is not in the flux path when the plunger is extended. As shown, Fig. 1, a laminated C-shaped core 10 surrounds a solenoid coil 36 into which slides a laminated T-shaped plunger 28. A rectangular groove is provided in each of the two faces of the head of the plunger which abut arms 22 and 24 of the C-stack 10 and a closed copper shading coil is brazed or silver soldered into each of these grooves. The lower end of the shank 27 of armature 28 may be provided with an inset anvil (32), Fig. 2, which engages a push-pin extending through an aperture 16 provided in the C-stack laminations to return the plunger to its extended position when the coil is unenergized. The shading coils and the anvil may be brazed to the plunger laminations in a single operation.

Title: Photographic camera
IPC: G03B15/04
Filed: 1970-11-23
Abstract: 1335673 Photographic cameras EASTMAN KODAK CO 23 Nov 1970 [22 Nov 1969] 55501/70 Heading G2A A photographic camera, having a rotatable receiver 7 for positioning percussive flash units having integral strikers 17a so that the lamps thereof are sequentially located at a firing site, is provided with means for indicating the presence of a fired flashlamp at the firing site. Insertion of a flash unit depresses a T bar 8 to the position shown, and this in turn depresses one end of a disabling lever 9 which is thereby withdrawn from engagement with a tab 13d of a control member 13 which in turn rotates anti-clockwise (as seen) under action of a spring 12. By virtue of aperture 13a and drive tab 15b, actuator member 15 is raised until its end 15a contacts an operative striker end 17a. However, if the flashbulb has been used, the striker end 17a will not lie in the path of the actuator member 15 which continues to rise until the motion of the control member 13 is stopped by a cam follower 21 engaging cam surface 7a. This additional upward motion causes an arm 13c to clear a signal blade 19 which is then pivoted to appear in the camera viewfinder 23. A picture taking operation with an unused flashbulb in the firing site is initiated by depressing a release 1, freeing a shutter driver 2 to move anticlockwise as seen. A cam surface 2a of the driver and a tab 13b of the control member 13 ensure that the actuator member 15 is raised to release the striker end 17a for firing the bulb. As with a used flashbulb, this additional upward movement causes the blade 19 to be visible in the viewfinder. As the receiver 7 is rotated (either manually or in response to the film winding mechanism), the cam surface 7a causes the members 13, 15 to return to their initial positions. When no flash unit is present Fig. 1,(not shown) the disabling lever 9 holds the control member 13 so that its tab 13b lies out of the path of the cam surface 2a. The signal blade 19 may be operated by a positive connection between a slot (19b) Figs.6 and 7, (not shown) therein and the arm 13c. An alternative mechanism for returning members 13, 15 to their initial positions is described with respect to Figs.8-11 (not shown). Reference has been directed by the Comptroller to Specification 1287455
