Abstract: 169,673. Munro, E. M. July 27, 1920. Drum or barrel winding. machines; driving - gear; brakes and retarding-apparatus; overwinding preventing; regulating and controltransmitting gear; selfsustaining gear.-A winding-drum, mounted loosely on its shaft, is driven therefrom by idle friction rollers carried by a swinging frame, which is rocked to bring the friction rollers into or out of driving engagement and also controls ratchet self-sustaining gear and a brake. The frame can be rocked by hand, or by a stop on the winding rope to avoid over-winding. The driving-shaft 5 carries a sleeve 11 slidably keyed thereon, a winding-drum 13, loose on the sleeve, being driven when idle rollers 17, 18 on a shaft 16 are respectively brought into engagement with friction drums 12, 19 on the sleeve and the winding-drum. The idle rollers are carried by a frame 15 rotatable eccentrically to the sleeve 11 on a frame 14 so that, when the frame 15 is rocked, the idle rollers are brought into or out of engagement with the driving and driven drums. In order to bring the winding-drum into any desired position along the shaft 5 the frame 14 can be traversed on wheels 47 along a track 48. A load-sustaining pawl 31 is brought into engagement with a ratchet-wheel 32 on the winding-drum when the frame 15 is rocked to cause the drum to be driven. The pawl is mounted with some lost motion on a shaft 30 rotated through a sector and pinion by an arm 26, which is pivoted on a shaft 29 and is connected to the frame 15 by a pin-and-slot connection with an arm 28. When the driving-gear is disconnected, the pawl remains engaged until released by a pull on a hand rope 42. A brake band 22 on the winding-drum is operated by a double-armed lever 23 on a shaft 25 having an arm 26 which is connected to the frame 15 in the same manner as the first arm 26, so that, after the friction gear has been disengaged, further movement of the frame 15 app.ies the brake. To prevent overwinding, the frame 15 is rocked to disengage the driving-gear and apply the brake by means of a stop 43 adjustably secured on the winding-rope, this stop coming into contact with an arm 46 which is carried by the frame 15 and through which the rope passes. The winch may be mounted on a motor vehicle as described in Specification 170,674.

Title: Manufacture of water-soluble organic iso thiouronium salts
Filed: 1955-07-29
Abstract: Emulsions are formed from chlorinated hydrocarbons, e.g tetrachloroalkanes of the formula bl(CH2)nCbl3, and isothiouronium salts containing a trihalogeno-alkyl group or a dihalogeno-alkenyl group and prepared by reacting a tetrahalogeno-alkane of the formula (halogen)3C-(CH2-CH2)n-halogen or a trihalogeno-alkene of the formula (halogen)2 C = CH-CH2-(CH2-CH2)n-1-halogen (wherein the halogen is chlorine or bromine and n is an integer from 1 to 10) with thiourea or a substituted thiourea, e.g. N-alkyl-, N : N1-dialkyl- or N : N-dialkylthioureas wherein the alkyl groups may be wholly or partially replaced by aryl groups, or N : N-alkylenethioureas.ALSO:Polyvinyl chloride is emulsified with isothiouronium salts containing a trihalogenoalkyl group or a dihalogeno-alkenyl group and prepared by reacting a tetrahalogeno-alkane of the formula (halogen)3C-(CH2-CH2)n-halogen or a trihalogeno-alkene of the formula (halogen)2C = CH-CH2-(CH2-CH2)n-1 - halogen (wherein the halogen is chlorine or bromine and n is an integer from 1 to 10) with thiourea or a substituted thiourea, e.g. N-alkyl-, N:N1-dialkyl- or N:N-dialkyl-thioureas wherein the alkyl groups may be wholly or partially replaced by aryl groups, or N:N-alkylene thioureas.ALSO:Isothiouronium salts containing a trihalogenoalkyl group or a dihalogenoalkenyl group are prepared by reacting a tetrahalogeno-alkane of the formula (halogen)3C-(CH2-CH2)n-halogen or a trihalogeno-alkene of the formula (hal)2C=CH-CH2-(CH2-CH2)n-1-hal (wherein the halogen is chlorine or bromine and n is an integer from 1 to 10) with thiourea or a substituted thiourea, e.g. N-alkyl-, N : N1-dialkyl- or N : N-dialkyl-thioureas wherein the alkyl groups may be wholly or partially replaced by aryl groups, or N : N-alkylene-thioureas.  The reaction is advantageously conducted in an organic solvent, e.g. ethanol, acetone, methyl ethyl ketone or methanol, with or without the addition of water.  The salts may be converted into the free bases by addition of weak bases such as ammonium hydroxide and the free bases may then be converted to other salts.  Alternatively, other salts may be formed by double decomposition, e.g. trichloropentyl-isothiouronium thiocyanate from the chloride and potassium thiocyanate.  In examples: (1) 1 : 1 : 1 : 5-tetrachloropentane and thiourea are refluxed in ethanol to give 1 : 1 : 1 - trichloropentyl - (5) - isothiouronium chloride; (2) 1 : 1 : 1 - trichloroheptyl - (7) - isothiouronium chloride is similarly prepared; (3) a mixture of 1 : 1 : 1 : o -tetrachloralkanes having the average constitution cl(CH2)16Ccl3 is reacted with thiourea as in (1) to give an o  : o  : o -trichloralkyl-(1)-isothiouronium chloride mixture; (4) ethylene thiourea and 1 : 1 : 1 : 5-tetrachloropentane similarly yield 2-(5 : 5 : 5-trichloropentyl) - mercapto - imidazoline hydrochloride; (5) 1 : 1 : 5-trichloropentene-(1) and thiourea similarly yield 1 : 1-dichloropenten-(1) yl-(5)-isothiouronium chloride; and (6) the process of (1) is performed in the absence of a solvent.

Title: Improvements relating to ground controlled rocket missiles
Inventor: SIMPSON JAMES CHARLES
IPC: F42B15/04
Filed: 1961-06-19
Abstract: 1,020,867. Self-propelled missiles. BRITISH AIRCRAFT CORPORATION (A.T.) Ltd. June 12, 1962 [June 19, 1961 (2); Aug. 1, 1961], Nos. 22100/61, 22135/61 and 27877/61. Heading F3A. A wire dispenser for a rocket missile controlled in flight by signals transmitted from a ground station to the missile through a control wire trailing therebetween, comprises, Fig. 1, a tubular former 11 mounted at the rear of the rocket motor (not shown) so that the jet nozzle extends through the interior of the former. A winding 13 of 4-core enamelled wire is wound helically in layers on the former, successive layers being shorter providing tapered ends 15, 16 to facilitate free release of the winding when the wire is pulled rearwardly during flight. The free end 21 of the winding may be anchored at the ground station by a bollard as disclosed in Specification 963,504. In a modification (not shown) the ends of the winding are formed in steps. To prevent unduly rapid paying out of the wire due to the rocket efflux at the initial stages of flight the penultimate layer of the winding 13 is painted with synthetic resin varnish and wound with a layer of tissue paper 17, the final layer being similarly painted and coated with an outer skin 19 of paper impregnated with the resin, the resin then being cured. Thus the paper is torn during the unwinding of the first two layers and provides a retarding action. Since an abrupt change of course may be imparted to the rocket during the first few yards of its travel it is desirable for the first few yards of the wire to be released very readily and accordingly an auxiliary wire coil is formed between the end 21 and the winding 13. The auxiliary coil may be wound on the tapered rear end 16 and secured by a skin of resin-impregnated paper (Fig. 2, not shown); alternatively (Fig. 3, not shown) it may be wound on the rear end of the cylindrical surface of the winding 13. In another modification (Fig. 4, not shown) the rear end of the former 11 is extended and the auxiliary coil wound thereon. In a further modification (Fig. 5, not shown) the auxiliary coil 60 is wound as a pan-cake on the winding 13 and covered by a paper disc 61.

Aug. 4, 1931, No. 22124. Convention date, Aug. 8, 1930. [Class 143.] Computing-apparatus.-A weighing scale provided with a double reading chart having a plurality of parallel columns so as to permit both the customer and the merchant to read the chart simultaneously comprises a movable shutter mechanism adapted to be selectively set to take a reading in any desired column and simultaneously restrict the customer's view of the chart to the single column selected by the merchant. A bar 23, secured longitudinally above the rotatable computing drum 7, supports a carriage 22 provided with lateral extensions carrying lenses 26, 26a to enable the salesman and customer respectively to read the weights and monetary values on the drum. The carriage is moved by a handle 32 and the setting and reading are facilitated by pointers 27, 27a and electric lamps 30, 30a. In order to obscure, on the customer's side of the scale, all the drum indications except the one to be read, a spring drum 40 is arranged adjacent each end of the viewing slot 20, and flexible tapes 35, 35<1> are lead from the drums so as to extend in front of the slot, the ends of the tapes being secured to the lens frame by screws 36 so as to leave a gap 37 sufficiently wide to expose one column of the computing drum. The weight and value numerals on the computing drum are in duplicate, the sets of numerals being inverted with respect to one another in order to afford normal reading on opposite sides of the machine. The weight readings for the salesman and customer are situated in the centre zone, and at one end respectively, of the drum. The weight-indicating range on the salesman's side is extended by continuing his weight graduations completely round the drum. The extended rotation of the drum to bring these additional weight graduations into view displays inverted value numerals at the view slots and thus prevents them from being readily read.
