Title: Cable winding device
IPC: H02G11/02
Filed: 1960-06-09
Abstract: 921,788. Taking up slack of supply cables. H. BROZIAT. June 9, 1960 [June 24, 1959; Dec. 4, 1959], No. 20281/60. Class 78 (2). The supply cable 11 of an electric motor 4 is wound on to a winding drum 8 which is automatically rotated to wind the cable in whenever the latter becomes slack, the rotation being effected by the reaction torque of the motor. In the motor mower shown, a cutting blade 9 is driven by motor shaft 3, which rotates about a vertical axis. The motor housing is also rotatable about the same axis in bearings 6 and is integral with the winding drum 8. When the cable is taut, the housing rotation is resisted and the motor output drives the cutter. Should the cable become slack, however, the housing tends to rotate in the opposite sense to shaft 3 and haul in the cable. The necessary reaction for this rotation of the housing is ensured by braking the normally driven shaft 3 by fan blades 10. In a modification (Fig. 2, not shown), the motor housing is fixed and a hollow cable drum is rotatably mounted thereon. In this case the fan blades 10 are carried by the upper end of the motor shaft 3 and move within an enclosure, which may be sealed and liquidfilled, defined by the top of the fixed motor housing and the cylindrical walls and plane top of the rotatable cable drum. In this form of the invention the cable is wound in the same sense as the shaft 3 is driven.

Title: Cracking and reforming of hydrocarbons
Filed: 1943-12-13
Abstract: A pyrolytic non-catalytic process for manufacturing naphthas having improved anti-knock rating and low unsaturation and being suitable for aviation fuel, comprises cracking a straight run naphtha distillate at temperatures of from about 545 DEG  to 565 DEG  C. at a pressure of from 300 to 1100 lbs. per sq. inch in the pseudo-liquid <FORM:0574567/IV/1> phase, fractionally distilling the cracked products to produce a first naphtha fraction boiling substantially between 80 DEG  and 225 DEG  C., recracking this fraction in the pseudo-liquid phase at a temperature of between 530 DEG  and 560 DEG C. and at a pressure of from 500 to 2000 lbs. in the presence of 5-15 per cent by volume of a light feed predominating in C3 hydrocarbons, fractionally distilling the recracked products to produce a second naphtha fraction boiling substantially between 90 DEG  and 225 DEG C. and having a higher anti-knock rating and a lower bromine value than the first naphtha.  Straight run naphtha distillate is cracked in zone 2 at 555 DEG  C. and 600 lbs.  The products are passed into fractionating zone 5 from which a first naphtha fraction of boiling range 100 DEG -200 DEG  C. is withdrawn and subjected to recracking at 550 DEG  C. and 600 lbs. in zone 9 into which C3 hydrocarbons are introduced through line 19 in the proportion of 10 per cent by volume of the first naphtha fraction.  The products are fractionated in zone 11 from which a second naphtha fraction of boiling range 105 DEG -200 DEG  C. is withdrawn through line 14 and may be subjected, in zones 25 and 27, to refining and blending.  The C3 hydrocarbons required in zone 9 may be obtained by fractionating in zone 15 the light fractions from zones 5 and 11.  A Venezuelan straight run naphtha when processed according to the invention and then sulphuric acid and doctor treated gave a product 60 Vol. per cent extractable with sulphuric acid and having initial and final boiling points of 110 DEG and 186 DEG  C. respectively, a bromine value of 4 and an octane number of 83.

Abstract: 446,872. Ink-ribbon mechanism. ROYAL TYPEWRITER CO., Inc., 2, Park Avenue, New York, U.S.A.-(Assignees of Handley, G. F. ; 7030, 83rd Street, Glendale, New York, U.S.A.) July 24, 1935, No. 21064. Convention date, Sept. 5, 1934. [Class 100 (iv)] In automatic reversal mechanism comprising a driving- shaft which is moved longitudinally by co-operation of worms thereon with pawls controlled by ribbon-guides, each pawl is moved into engagement with its worm by means of a cam actuated by the ribbonguide, and on return of the pawl, the cam returns the ribbon-guide. In the mechanism shown in Figs. 1 and 6, each spool-shaft 9 is provided with a gear 13 for co-operating with a driving-gear 14 on a longitudinally movable driving-shaft 12 provided with a V-grooved collar 18 co-operating with a spring detent 21. Each spool 10 is associated with a ribbon-guide 23 controlling engagement of a vertically movable pawl 29 with a worm 32 on the driving-shaft. The ribbon-guide is constrained to move horizontally by means of a slot 25 and finger 24. The pawl is guided by brackets 7, 8 and is held in raised position by a spring 31. The bottom of the pawl is skewed to register with the teeth of the worm. A cam or incline 28 on the ribbon-guide co-operates with a dog 33 which is pivoted on the pawl and is formed with concentric and eccentric parts 35, 36 for engaging the bracket 7, the concentric part being normally in engagement. When either spool is exhausted, a button 22 on the ribbon 11 displaces the associated ribbon-guide, the dog 33 is rocked by means of the cam 28, and the part 36 depresses the pawl into engagement with the worm 32. Thereupon, the driving-shaft is moved longitudinally to effect engagement of the driving-gear and to release the worm from the pawl. Reversal occurs immediately, and during return of the pawl to normal position by means of the spring 31, the ribbon guide is returned slowly by co-operation of the dog 34 and cam 38, the slow returnmovement preventing formation of slack in the part of the ribbon between the button and spool. The dogs 33 may be provided, beyond the eccentric part 36, with a concentric part for preventing the pawls 29 from jamming the worms and thereby preventing longitudinal movement of the driving-shaft. The driving- shaft may be provided with conical cams 43 for positively initiating return movement of the pawls. If both ribbon-guides are moved manually, the cams prevent jamming of the reversing-mechanism, since the pawl associated with the winding-spool is prevented by the subjacent cam from being depressed below the periphery of the worm and thereby preventing longitudinal movement of the driving-shaft. Specification 344,033 is referred to.

Classes 29 and 64(3) Air to be cooled, for example for an aircraft cabin, is passed through an exchanger 7 in which a liquid, such as water, alcohol or ammonia, is circulated and arranged to evaporate at a part of the exchanger where it is not in heat - exchange relationship with the air. The latter may be supplied by the compressor of a propulsion engine and is cooled before passing into the exchanger 7 by an exchanger 3 through which air from the inlet of the compressor is drawn by a fan 11 driven by a turbine 9. This turbine is driven by air leaving the exchanger 7 which may be by-passed by a pipe 12 when a cock 13 is closed and a cock 14 opened. The air passes through a cluster of tubes 19 in the evaporator while the liquid is passed in countercurrent round a series of baffles 23 by a pump 29 connecting inlet and outlet openings 25 and 28. Evaporation occurs above a plate 24 where the liquid which may be passed through a loaded valve 40 is at a lower pressure and in contact with atmosphere through a porous partition 31 and a vent 26. The plate 24 may be perforated. If the cabin is substantially airtight it may form part of a closed circuit in which air is circulated by a fan. Liquid losses from the exchanger 7 may be replaced from a tank having liquid supply and air vent valves controlled by a float in the exchanger.
