Filed: 1975-02-21
Abstract: 1459718 Tape dispensers ZBROJOVKA BRNO NARODNI PODNIK 21 Feb 1975 [25 Feb 1974] 7438/75 Heading B8M In a device for the correction of punched tape 23 with a sealing tape 4, a roll 3 of sealing tape 4 wound upon an elastic sleeve 18 is removably mounted on a support 17 provided with at least two supporting areas 29 for the sleeve 18, the distance of at least one area 29 from the rotational axis of the core 17 being greater than the inner radius of the undeformed sleeve 18. As shown, the roll 3 is supported between arms 6, 61 of a bracket 5. Apertures 7, 7<SP>1</SP> are provided in the arms 6, 6<SP>1</SP> and a bearing 8 is fixed in the aperture 7 to slidably receive a journal 9 having a blind bore 10. Projections 16, 16<SP>1</SP> on the support 17 are received in the bore 10 and the aperture 7<SP>1</SP>, respectively. Alternatively, projections may be formed on the arm 7<SP>1</SP> and the journal 9 to engage in bores in the support 17. A resilient arm 11 fixed to the arm 6 by bolts 12 urges the journal 9 towards the core 17 and has a slot 13 to receive an annular groove 14 of the journal 9. The elastic sleeve 18 may be made of plastics material. The support 17 may be shaped as shown in Fig. 3a or have a triangular or rectangular cross-section, Figs. 3b and 3c (both not shown). For concentric mounting of the roll 3, the distance of the areas 29 from the axis P of rotation of the support 17 is the same, but greater than the inner radius of the undeformed sleeve 18 and, for eccentric mounting, the areas 29 are unequal distances from the axis P with at least one area 29 at a distance from this axis greater than the undeformed inner radius. Tape from the roll 3 passes over a guide pulley 20 and over a divided pulley comprising rings 25, 31, 32 rotatably mounted on a shaft 21 and between which are fixed knives 24, 24<SP>1</SP> for longitudinally slitting the tape 4. To fit a new roll 3, a curved portion 15 of the arm 11 is moved in the direction S so that the journal 9 is partly pulled out from the bearing 8 and the support 17 can be released. The arm 11 is released and the sleeve 18 is removed from the support 17. The sleeve 18 of a new roll 3 is deformed slightly and the support 17 inserted therein. The arm 11 is moved outwardly again to allow the new roll on the support 17 to be inserted. The roll 3 and the sleeve 18 are shifted on the support 17 to abut an adjustable stop 19. One side of the roll 3, the stop 19 and surface 26 on a collar 30 on the ring 25 lie in the same plane B which extends transversely of the punched tape 23 into a gap between adjacent code holes 27 and the sprocket holes 28.

Title: Improvements in or relating to the measurement of electrical quantities
IPC: G01R1/30
Filed: 1936-03-14
Abstract: 472,168. Current and pressure meters; resistance measurements. COMPAGNIE POUR LA FABRICATION DES COMPTEURS ET MATERIEL D'USINES A GAZ. March 14, 1936, No. 7765. Convention date, March 15, 1935. [Class 37] A method of measuring voltage, current, or resistance consists in utilizing a critical operating point of a gas discharge tube, the discharge of which changes suddenly from an unstable to a stable condition, the voltage across and the current through the tube being then known, by connecting a resistance and a condenser-gasdischarge tube relaxation circuit across a potentiometer and adjusting the slider of the potentiometer until the discharge enters into a stable condition. As applied to the measurement of a resistance 3, the discharge tube 1 and a condenser 2 are connected in parallel so as to form a relaxation oscillator, the condenser being charged through the resistance 3 to a variable voltage obtained from a battery 4 through a potentiometer 5. The contact of the potentiometer is adjusted until the discharge just ceases to be intermittent and becomes continuous. At this point, from the known current-voltage characteristic of the discharge tube, the voltage applied to the tube and the current flowing therethrough are known, and, since the total applied voltage is also known, the value of the resistance 3 can be determined and may be read off on a scale over which is moved a pointer rigid with the slider of the potentiometer. If the voltage 4 is not constant, the scale may be movable being driven by a lug arranged on the potentiometer slider and moved through such a distance as to correct for any variation in the voltage of the supply, the extent of the movement being previously determined by connecting the points C and A directly, and applying first the normal supply voltage and then the supply voltage to be used ; in each case the position of the slider of the potentiometer at which the discharge becomes stable is found and the difference between the two readings indicates the extent to which the potentiometer scale must be adjusted. After the adjustment has been made, the lug disengages the scale and the pointer moves over the scale as the potentiometer slider continues its movement until the discharge becomes stable. Voltage may be measured by finding the stable point first with a known voltage and then with the voltage to be measured. Current may similarly be measured by passing it through a known resistance or directly through the potentiometer 5.

Title: Improvements in and relating to the treatment of textile fibres to improve or modify the handle, dyeing affinities, and other properties
IPC: D06M13/224
Filed: 1942-06-08
Abstract: 558,892. Treating textiles with liquids. COURTAULDS, Ltd., and MACGREGOR, J. H. June 8, 1942, No. 7770. [Classes 2 (iii) and 15 (ii)] Textile fibres, yarns, fabrics, and the like are treated with an aqueous solution containing a guanidine salt of a monoalkyl ester of an aliphatic dibasic acid in order to improve or modify the handle and other properties. The process of Specification 546,050 is excluded. Aminoguanidine salts may be used instead of guanidine salts. The guanidine salts of long chain alkyl esters of aliphatic dicarboxylic acids are good wetting, dispersing, emulsifying, or detergent agents. When employed in conjunction with formaldehyde the guanidine salts impart wool-like dyeing properties to cellulose as well as giving the fibre a soft and silky handle. The guanidine salts may be used with urea and formaldehyde, the cellulosic textile fibres being treated with the solution and then heated to convert the urea-formaldehyde into an insoluble compound so as to render the material crease resistant. In an example, diethyl oxalate dissolved in ethanol is refluxed with guanidine carbonate, and guanidine ethyl oxalate is obtained. Viscose staple fibre is soaked in a solution of this salt containing formaldehyde. The material is squeezed, dried, and heated. It is then dyed with an aqueous solution of Tartrazine KS containing formic acid. In another example, viscose staple fibre is treated with guanidine isopropyl oxalate and formaldehyde and then dyed with Coomassie Red P.G.S. Viscose staple fibre is treated with guanidine n-butyl oxalate and formaldehyde and then dyed with Eriochrome Black T. It is subsequently treated with sodium dichromate. In another example, dioctyl succinate is prepared by treating 2-ethylhexanol with succinyl chloride. It is boiled with guanidine carbonate in ethanol to produce guanidine octyl succinate. Viscose satin fabric is soaked in a solution of this salt containing formaldehyde. The fabric is squeezed, dried, and heated. It is then dyed with Chlorantine Fast Blue 3GLL. The dyeing is fast to washing and light and the material has a resilient, soft silky handle. Viscose satin fabric is treated with guanidine cetyl succinate and formaldehyde, and then dried and heated. It is dyed with Diphenyl Fast Red 7 BL. Viscose staple fibre fabric is treated with a solution of guanidine octyl succinate and a water-soluble ureaformaldehyde condensation product containing ammonium sulphate. The fabric is squeezed, dried on a stenter, and heated. It is rendered crease-resistant but has a soft handle. Viscose fabric is soaked in a warm solution of guanidine stearyl adipate containing acetic acid. It is rinsed with soft water and dried. It has a soft silky handle. Viscose fabric is treated with guanidine octyl succinate solution containing acetic acid. It is rinsed, dried and stentered. The treated fabric has a soft handle and is resistant to slippage of the threads.

Abstract: 526,282. Coking processes. STEINMETZ, W. March 11, 1939, No. 7928. Convention date, March 16, 1938. [Class 55 (i)] In the low temperature carbonization of coal, peat, shale and the like between 250‹ and 600‹C. and preferably between 450‹ and 550‹C. in the presence of catalysts, nitrogen is brought into direct and indirect contact with the charge during the whole coking period. Compounds of the heavy metals Fe, Cu, Ni &c. or of the light metals Al, Mg &c. are suitable as catalysts. The charge should contain its natural amount of moisture for example 16-20 per cent. by weight: A pressure of 10 atmospheres may be employed. The coke obtained may be used as " active carbon," and after being washed with an acid and an alkali in succession, its use as an adsorbent is improved.

Abstract: 195,385. Coursier, E. J. E., and Piestrak, C. S. March 22, 1922, [Convention date]. Void [Published under Sect. 91 of the Act]. Variable-speed epicyclic gearing.-One member of an epicyclic gear for motor vehicles &c. is controlled either by a brake or by a liquid pump so as to obtain either definite forward or reverse speeds or automatically controlled speed changes. A pinion 7 on the driving shaft 6 gears with double pinions 8, 11 loose on an arm 9 carried by the driven shaft 10. The pinions 11 gear with loose wheels 12, 13, the wheel 12 being provided with braking means and the wheel 13 being connected to the casing 14 of a pump. This casing carries pinions 15 meshing with pinions 16 on the shaft 6 to form a gear pump, the oil or other liquid being supplied to the casing through mlets 18 and exhausted through outlets 21. The outlets 21 are controlled by a spring-pressed valve 20 which may be operated by a lever 23. When the outlets 21 are fully closed, the gear rotates solidly; normally the pressure of liquid acting on the valve 200 against the spring pressure provides automatic means for throttling the exhaust and thereby varying the speed. By braking the wheel 12, the gear drives independently of the pump control and by braking the casing 14 a reverse drive is obtained. Other forms of epicyclic gears or pump may be employed.

Abstract: 371,126. Coin-freed game apparatus. STOLZ, O., 19, Frobenstrasse, Berlin. March 16, 1931, No. 8077. [Class 27.] Shooting apparatus.- A dummy rifle for practice shooting is provided with two transparent targets in its barrel a, through which a beam of light is passed to throw the images of the target on a target surface. One target i, Fig. 2, is situated in a transverse vertical slot h<1>, Fig. 4, in a frame h and is suspended by an eye i<1> from an arm l<1> of a pendulum l pivoted at l<2>. The other target n is pivoted at n<2> and is normally out of the way as shown in Fig. 1. An electric lamp e with a switch c is fitted at the breech end, and a lens m at the muzzle to illuminate the target i and throw its image on a target surface. When aim is taken and a trigger s is pulled, this releases a sliding rod p which is drawn back by a spring r, whereupon a spring p<1> at the front end of the rod p bears on an arm o extending from the target n and swings the target n up against the target i, which is thus held in the position it occupies when the trigger is pulled. The target n has a centre spot which indicates the axis of the barrel, so that any divergence between this spot and the centre of the target i indicates the error of the aim ; and this indication is retained until the rifle is recocked. Coin action, thrust ; coin discharging ; mechanism.--The trigger s may be locked by a lever u until this is deflected by a coin t inserted through a slot v. When the trigger is pulled, the lever u is rocked further and lifts the rear end of the rod p, thereby allowing the coin t to fall in a receptacle w.
