Patent GB-816052-A (GB)
Title: Improvements in the manufacture of cellulose triacetate filamentary materials
Inventor: DOWNING JOHN
IPC: D01F2/30
Filed: 1955-12-12
Abstract: Cellulose triacetate filaments are made by dry-spinning a solution of cellulose triacetate in methylene chloride, or in a mixture of methylene chloride and methanol or ethanol containing at least 88 per cent by weight of methylene chloride, into an evaporative medium, the absolute humidity of which, at least in the neighbourhood of the point of extrusion, is adjusted to a value of or below a critical maximum which is linearly related to the average temperature of the evaporative medium surrounding the filaments from the point of extrusion to the point at which they are substantially fully set, the humidity being 4.7 grams/cubic foot at 48 DEG  C. and 3 grams/cubic foot at 28 DEG  C., subject to an over-riding maximum of 5 grams/cubic foot.  The spinning solution, which preferably contains between 17 and 27 per cent of cellulose triacetate, is preferably extruded at a temperature above 40 DEG  C., the cell being so heated that the average temperature of the evaporative medium is 40-50 DEG C.  A proportion of specially conditioned air or other evaporative medium, e.g. more than 10 per cent of the total evaporative medium, is preferably introduced through downwardly-facing, equally-spaced, openings in an annular distributer surrounding the jet or above and coaxial with the jet, the remainder of the air required being introduced at a lower level from the surrounding atmosphere, so that the resulting humidity of the mixture is below the critical maximum.

Title: Power driven article conveyor
Inventor: LEACH JOHN MEREDITH
IPC: B65G47/26
Filed: 1970-07-23
Abstract: 1,267,309. Roller conveyers. J. M. LEACH. 23 July, 1970, No. 35747/70. Heading B8A. An accumulation conveyer comprises pairs of article-supporting rollers 74, 80 driven by friction wheels 26 which rotate with V-pulleys 32. A cross-section of the V-area of each pulley is cut out at 106 and a stud 104 centred on the area 106 is attached to each wheel 26. A driven V-belt 86 engages the V-pulleys 32. Between each pair of rollers 74, 80 an article sensor is rockable on a stud 112 and is resiliently urged upwardly to the shown position. Each sensor is maintained in one or other of two extreme positions in which its lower end rests over one or the other of adjacent ends of levers pivoted at 108. The other ends of the levers 114 terminate adjacent the studs 104 when the studs are in the positions shown, these positions also corresponding to the positions of cut-out areas 72 in the treads of the friction wheels 26. When articles are conveyed in the direction C, all the sensors will have been rotated to the shown positions and, as each article passes over the sensors, the latter, together with the adjacent end of the associated lever 114, will be depressed. The opposite end will thus be raised into engagement with the stud 104 and will stop rotation of the wheel 26 and V-pulley 32. If the leading article continues to move, interruption of the drive to the wheel 26 is brief and the following article will continue its movement since the rollers 74, 80 on which it is supported will be free to rotate due to the cut-out areas 72 of the wheel 26. If the leading article is stopped by a stop bar, the associated sensor will remain depressed and following articles will not be driven. The provision of a pair of levers 114 beneath each sensor also enables the sensors to operate when the articles are conveyed in the direction D, the sensors then being rocked to the other limit positions as defined by stops 118.

Title: Improvements in or relating to the concentration of aqueous dispersions of rubber
Inventor: KEMP IAN
IPC: C08C1/075
Filed: 1953-12-24
Abstract: An aqueous solution of natural or synthetic rubber is concentrated by partial freezing at a temperature lying between -5 DEG  and -20 DEG C., separating at the same temperature the partially frozen dispersion into a fraction containing substantially all the rubber in the dispersion, and a solid ice fraction containing substantially no rubber.  Rubber latex preserved with ammonia may be partially frozen at -10 DEG  to -12 DEG C., placed in a basket centrifuge maintained at that temperature and separated into a concentrated latex of 70 per cent solids content and an ice fraction of 10 per cent total latex solids content.  The separating may, alternatively, be effected by filtering through a wire mesh filter in a cooled plunger press.  As a further alternative a precooled rubber dispersion may be introduced at such a rate into a rotating centrifuge maintained at between -5 and -20 DEG C. that it is substantially instantaneously partially frozen, and is thereupon separated centrifugally into its liquid and solid phases.  Specification 478,406 is referred to.

Title: Constant speed multi-frequency electrical generating apparatus
IPC: H02K19/34
Filed: 1928-12-08
Abstract: 322,347. Dornig, W. Dec. 8, 1928. Inductor-alternators. - In a multifrequency generator of the homopolar inductor type comprising a number of independent stator-rotor units supplying different frequencies, the units or groups of units having a common exciting core, and the generator being driven by a motor which is maintained at constant speed, the reluctances of the magnetic paths for successive units are adjusted for the optimum value of the flux by selecting the dimensions of the air gaps or by increasing the iron cross section of the generators successively as their distance from the source of flux, increases. As shown applied to a generator 1 producing ten separate currents of different frequencies, the exciting coil 4 is at the centre, and the stator units 2a - - 2<k> are provided with generating windings located in slots. The stator units, and the rotor units 3<a> - - 3k are formed with diminishing air-gaps and increasing cross-section as their distance from the exciting coil increases. The exciting coil may be located at one end of the machine, and if a greater number of frequencies is required, an exciting coil may be provided for each group of generating units, for example, for each group of ten units in a machine producing twenty frequencies. The motor 5 is maintained at constant speed, preferably by means of a centrifugal governor 6, and the generator 1, motor 5 and governor 6 may be located in a common housing.

Title: Hydraulic shock absorbers more particularly for vehicles of all kinds
IPC: F16F9/22
Filed: 1933-12-27
Abstract: 431,265. Hydraulic shock-absorbers. DEUTSCH, F. A., 27, Rankestrasse, Berlin. Dec. 27, 1933, No. 36426. [Class 108 (iii)] In a hydraulic shock-absorber of the piston- and - cylinder type particularly for vehicles, the piston-operating cam or tappet or other operating member or members is arranged within the profile of the driving shaft. The shaft 2 may be shaped as shown in Fig. 1, to provide cams 11 for operating spring- pressed pistons 3 arranged in triplicate on each side of the shaft. On rotation of the shaft in either direction the fluid passes to the reservoir N through a lateral throttling passage in an adjustably spring-pressed valve 12, Fig. 3, containing a replenishing ballvalve 13. In order to vary the damping action for both directions of rotation of the shaft there may be unequal numbers of pistons on each side of the shaft and the pistons may be of different sizes. Fig. 4 shows a single-acting shock-absorber in which a pin 10 set in the shaft 2 operates a pair of pistons 3. In a second single-acting construction, Figs. 6 and 7, the working chambers 16 communicate through passages 17 with a regulating valve 14 loaded by a spring 18 which presses a piston 19 into contact with a pin 20 in the shaft so that the pressure of the spring 18 and therefore the damping action decreases with the stroke of the pistons 3. By arranging the regulating device 18, 19 on the same side of the shaft as the pistons 3, the damping action increases with the stroke of the pistons. The invention may be applied to shockabsorbers for independently-sprung vehicle wheels.

[Classes 35 and 38 (ii).] Relates to arrangements for controlling arc-discharge apparatus such as rectifiers or inverters in which the critical ignition voltage is raised above the normal operating voltage, ignition being effected at a predetermined moment by application of a high voltage to the anodes as described in the parent Specification, and consists in deriving the ignition potentials from an alternator adapted to produce a voltage of peaked wave form. In the arrangement shown in Fig. 1, a rectifier a feeding a D.C. network g from a transformer e is provided with grids c so energized as to raise the ignition voltage above the voltage of the transformer e. Ignition potentials are derived from the alternator h comprising a permanent magnet or separately excited field system rotated synchronously with the frequency of the supply network. The stator coils m are associated with condensers i whereby the peaky characteristic of the voltage wave is further developed, and are connected to the anodes b through spark gaps or discharge tubes k which may be asymmetric in character in order to suppress the negative half waves. Figs. 2 and 3 show an alternative form of alternator comprising a series of " transformers " t comprising exciting coils n and secondary coils m connected to the anodes. A disc s rotated synchronously with the network frequency carries a tooth z shaped so as to produce steep-fronted potential waves in the windings m as it passes through gaps formed in the transformer cores.

Abstract: 1,157,663. Photographic cameras. EASTMAN KODAK CO. Aug.16,1966 [Aug. 16, 1965], No.36621/66. Heading G2A. A photographic camera comprises a rotatable socket 15 for receiving a manually rotatable flash cube 16, rotation of the cube sequentially connecting the lamps in a flash circuit, there being a coupling between a drive member 31 rotated by the cube and a film advancing member and/or a shutter setting member. Assuming that an exposure has just occurred, the flash cube and socket are rotated manually through 90 degrees in a clockwise direction (as seen). Film Advance Rotation of the socket is transmitted via a gear 34 and shafts 36, 40 to the film take up roll (on right of cartridge). The film contains perforations 7 one of which is engaged by a spur 57 of a lever 50 which is moved to the right as the film is advanced. This movement brings a pawl 54 into contact with a ratchet 38 rotation of which releases a spring clutch 39 and disengages the shafts 36, 40 so as to terminate the film advance when the required amount of film has been wound on, irrespective of how far the cube has been turned. Cocking Movement Rotation of the socket also causes a pin 32 contacting a lip 71 of a shutter actuating arm 60 to displace the arm to the position shown where it is held by an arm 80, the pin 32 then escaping from the lip 71. The camera is now ready for the next exposure, which occurs by an operator releasing the arm 80. As the arm 60 is moved to the right by a spring 67, a conventional shutter mechanism, (not shown), is operated, and an extension 65 pivots the lever 50 so as to disengage the spur 57 from the perforation 7. A spring 59 then disengages the pawl 54 and ratchet 38 so as to prepare the camera for the next winding sequence. In another embodiment Figs. 7-10, (not shown) a spring motor is provided to rotate an inserted flash-cube. Reference has been directed by the Comptroller to Specification 1, 034, 909.
