Patent GB-433542-A (GB)
Title: An improved system of natural-colour kinematography
IPC: G03B33/00
Filed: 1934-02-14
Abstract: 433,542. Colour kinematography. CRICKS, R. H., 159, Wardour Street, London, and GREENE, C. FRIESE-, 23, Normandy Avenue, Barnet, Hertfordshire. Feb. 14, 1934, No. 4852. [Classes 97 (i) and 98 (ii)] The colour-record picture frames produced by simultaneously exposing two negative films running at half the desired projection speed, and the frames produced by printing such frames in alternation on a positive film, occupy substantially the whole film area normally reserved for pictures. The negative films may be exposed as a bi-pack, or by means of a beam-splitting prism and gates at right-angles. In a bi-pack, the film nearer the lens may have an orthochromatic emulsion on the side further from the lens, the emulsions being covered with a filter stratum for a panchromatic emulsion in contact with it and carried by the rear film; the redsensitive negative is thus produced further from the lens than the other, and compensation for the longer focus of the lens at the red end of the spectrum is effected. Compensation for difference in size of the images is effected by adjustment during printing or by control of the shrinkage of the negatives during processing. The positive film may be projected through separate filters or may carry filters sprayed thereon ; dyes described in Specification 233,129, [Class 97 (i)], may be used. The colour bands of the filters, both in taking and projecting, may overlap to reduce colour pulsation and to secure lighter tints in the projected picture. The images may be projected successively by means of a shutter making one revolution for two frames and having unequally spaced apertures. The shutter may, alternatively, make one revolution for each frame, and may have a normal cover blade E, a narrower opaque flicker blade F, a narrow red sector R on one side of the blade F, and a narrow green sector G on the other side of the blade F.

Filed: 1919-02-26
Abstract: 123,986. Savy, E. L. A. Feb. 14, 1918, [Convention date]. Bottles, jars, cans, &c., drying.- The drying by hot air and subsequent cooling of bottles, jars, &c. as described in Specification 123,769 is effected in a continuous manner by placing the bottles on nozzles 6 attached to an endless conveyer 2 which carries the bottles over a hot air chamber 7 and then over a coldair chamber 14. The air is supplied to these chambers by blowers and distributing pipes 10, 29 and the escaping air is collected by hoods 19, 17. The hot air supplied to the chamber 7 and heated in the casing 12 is drawn from the hood 17, and has therefore already been warmed by contact with the bottles. The conveyer is composed of closely-fitting plates hinged to one another, and tight joints at the entry 6 and exit from each chamber are provided by flexible material forced upwards into contact with the conveyer plates by springs enclosed in casings 9.

Abstract: 194,118. Baker, W. Feb. 20, 1922. Breech actions, drop-down barrel. - A firing mechanism for a drop-down gun having a single barrel and a top-lever locking- action, comprises a pivoted hammer d situated behind the top lever and having a projecting finger-piece e at its upper end, and a firing-pin c mounted in alignment with the axis of the barrel. The hammer spring f is mounted in a hollow butt-tang and acts on the hammer through a sliding thrust-piece h. The hammer is moved to half-cock when the gun is opened by a rod n operated by a plunger l, Fig. 4, engaging a cam on the locking spindle. The plunger l also acts as a stop to limit the rotation of the spindle. The rod n is pressed forwards by a spring r abutting against a plate o which is hinged at the top to the action body and at the bottom presses against the trigger, so that the single spring r controls both the trigger and the locking mechanism.

Abstract: 785,376. Foam generating apparatus. PYRENE CO., Ltd. May 18, 1956 [Feb. 18, 1955], No. 4989/55. Class 47 An air-foam generating apparatus comprises a foam tube 6 having a substantially cylindrical foam generating chamber containing a gauze 7 or other obstruction to the flow so as to increase the mixing of the liquid and air, and a contracting part terminating in a nozzle, the ratio of the mean cross-sectional area of the foam-developing chamber to the cross-sectional area of the nozzle being between 2.25:1 and 5:1, the ratio of the square of the length (A to B) of the foam developing chamber to the cross-sectional area of the nozzle is between 11.5:1 and 26:1, and the length (B to C) of the contracting part being between 1/3 and 1/2 of the overall length (A to C). In an apparatus designed to work with a pressurized solution of foam-stabilizing compound in water as in Fig. 1, the ratio of the square of the length of the foam developing chamber to the cross-sectional area of the nozzle is between 11.5:1 and 20:1, but in an apparatus wherein the foam stabilizing compound is induced by the water stream, this ratio is between 15.5:1 and 26:1. An apparatus wherein the stabilizing compound is induced by the water stream as shown in Fig. 3 wherein the water passes through an orifice 15 having a sharp corner 19 upstream, and induces foam stabilizing compound through an opening 22 and then passes through a slightly smaller orifice 23 which is axially adjustable. The obstruction in the foam developing chamber is constituted by a rib 25.

Title: Method of and apparatus for mechanically treating flax stalks for production of a cleaned mass of flax fibre in staple length
IPC: D01B9/00
Filed: 1935-02-16
Abstract: 448,571. Obtaining flax or like bast fibres in staple length. PLATT BROS. & CO., Ltd., Hartford Works, WILKINSON, H., 49, Queen's Road, and PILKINGTON, N., 49, Edward Street, all in Oldham. Feb. 16, 1935, No. 5025. [Classes 120 (i) and 120 (iii)] Staple fibres of flax or like bast fibre for subsequent treatment to obtain a fibrous mass or lap of flax or the like for mixing with cotton or other textile fibres are produced by a continuous process consisting in mechanically feeding, crushing, decorticating and crimping the flax which is then stripped and de-crimped, the mass of flax being then delivered and further cleaned and broken into staple lengths by beating or opening, the cleaned and staple length fibres then being conveyed and delivered pneumatically. In one form of apparatus, the flax straws are fed by a lattice a and collecting feed roller b, Figs. 1 and 2, through fluted crushing rollers c, c<1>, spring- pressed and geared together, then through a succession of pairs of spring-pressed fluted decorticating rollers, e.g. four pairs d<1>, d<1x> ... d<4>, d4x, then through stripping rollers f<1>, f<1x>, f<2>, f<2x>, and delivery rollers g, g<1> to a beater or opener i. The bottom rollers in the decorticating range d<1> ... d4x are positively driven, the upper rollers being driven by contact therewith or positively geared thereto. The rollers are driven at constant speed but diminish progressively in diameter so that there is a progressive reduction in surface speed so as to crush and slightly crimp the flax. The stripping rollers f<1> .. f<2x> are of equal diameter and are spring-pressed and geared together and driven so as to run slightly faster than the rollers d4, d<4x> so as to exercise a slight drafting action which serves to separate the bark &c. from the fibre, and also to take out the crimp -imparted by the decorticating rollers. The shallow-fluted delivery rollers g, g<1> are spring-pressed together and positively driven at a slightly higher speed than the stripping rollers. The opener i, which is somewhat similar to that described in Specification 177,017, [Class 120 (i)], has a grid extending for about 90 degrees and a cover k of woven wire mesh extending for about 180 degrees, a pneumatic delivery pipe m with an air intake at n and a perforated sheet o leading to a storage receptacle, or if desired to a dusting machine or opener for removing any remaining trash, from whence the clean and staple length fibre is delivered for any subsequent treatment. The staple length into which the fibres are broken is controlled by the relative speed of the rollers g, g<1> and beater or opener i. The separated trash is collected in compartments h, h<x> and removed, e.g. by suction pipes h2 or a conveying apron. The Provisional Specification refers to lateral reciprocation of the decorticating rollers.
