Title: Improvements in photographic developer compositions
IPC: G03C5/30
Filed: 1952-09-01
Abstract: 720,235. Photographic developers. KODAK, Ltd. Sept. 1, 1952 [Sept. 1, 1951], No. 21954/52. Class 98 (2). Exposed silver halide emulsions are developed with an aqueous solution of pH 2.5 to 4.5 containing a ferrous or titanous salt and a chelating compound consisting of an aliphatic aminopolycarboxylic acid or a water-soluble salt thereof, in each amino group present, there being not more than one hydrogen atom directly attached to the nitrogen atom. Typically the metal salt is ferrous sulphate or titanous chloride while the chelating compound is the tetrasodium salt of ethylenediamine tetracetic acid. Optionally these solutions may contain potassium bromide to reduce fog but with accompanying loss of speed, while the speed may be increased by raising the pH. With titanous salts the pH can be raised only up to 5, beyond which the accompanying increase in fog is uncontrollable. In further examples, the developer comprises (1) a solution containing ferrous sulphate and trimethylamine tricarboxylic acid, or (2) a solution of titanous chloride and the trisodium salt of ethylenediamine, tetracetate, and potassium bromide with the pH adjusted to 4. Alternative metal salts mentioned are ferrous chloride, titanous sulphate and other ferrous or titanous halides while alternative chelating compounds are diethylenetriamine diacetic acid and methylene diamine tetracetic acid. The developers may be re-activated after exhaustion by electrolysis between a lead electrode in the developer solution and a carbon electrode in a solution of the chelating compound used in the developer in a porous cup within the developer. U.S.A. Specification 2,130,505 is referred to for the production of the chelating compounds.

Title: Improvements in or relating to bandages, dressings and the like
IPC: A61F13/02
Filed: 1953-08-12
Abstract: Cotton fabric is rendered self-adhesive and elastic, so as to be suitable for use as a surgical dressing, by treatment with a caustic alkaline solution of mercerizing strength while allowing free shrinkage in all directions.  In one example cotton gauze is immersed for five minutes in 60 DEG Tw. caustic soda solution, then rinsed in water, until neutral and dried.  The fabric may be treated with a solution of acetic acid, a solution of colloidal silica or an emulsion of cetyl alcohol after the rinsing, in order to improve the softness of the dressing.  A waterproof finish may be obtained by subjecting it to a final impregnation with a silicone resin.  The fabric has a thread density between 20 and 100 per square inch and weighs not more than 50 grams per square yard.  A knitted material has the same limit as to weight and is of not more than 25 needles to the inch.ALSO:Flexible, self-adhesive surgical dressings are made by treating cotton gauze or knitted material with a caustic alkaline solution of mercerising strength, while allowing free shrinkage. This treatment renders the cotton self-adhesive and sufficiently elastic to permit stretching over joints and muscles.  The fabric remains air-permeable.  In one example cotton gauze is immersed for five minutes in caustic soda solution of strength 60 DEG Tw., then rinsed in water until neutral and dried.  It is also proposed to give the dressing treatment with 1/2 per cent solution of acetic acid, 1/2 per cent solution of colloidal silica or 1/4 per cent. emulsified cetyl alcohol after the rinsing step, in order to modify the softness of the dressing.  The dressing may be made waterproof by subjecting it to a final treatment of impregnation with 3 per cent w/w of silicone resin.

IPC: D01G1/04
Filed: 1952-05-16
Abstract: <PICT:0750066/IV(c)/1> Apparatus for the production or treatment of staple fibres comprises an upwardly inclined trough, means for depositing chips in the lower end of the trough, each chip containing a large number of fibres packed together, and means for directing a stream of liquid upwardly along the trough to separate the fibres of the chips and to sweep the fibres over the edge of the trough.  The fibres may then be received in apparatus as described in Specification 750,065 [Group I] such apparatus comprising a receiving tank having an opening the floor thereof, and a perforated belt positioned beneath the opening and positively driven, whereby the mixture of liquid and staple fibres fed into the tank flows on to the belt and the fibres are thereby separated from the liquid.  The fibres retained on the belt may be compacted in the form of a blanket, from which further liquid can be expressed by means of a positively driven weighted roller resting on the fibres deposited on the belt.  The apparatus may be associated with apparatus for cutting a tow of continuous filaments, e.g. of viscose rayon, into short pieces or chips.  The apparatus may form part of a combined apparatus for producing continuous filaments, e.g. of viscose rayon, stretching and washing the formed filaments, cutting them into staple fibres, and opening up and collecting the staple fibres.  As shown, a tow of artificial filaments 53 is delivered by a forwarding device 112, and passes between a pair of vertical guide rollers 113, round roller 114, and between positively driven nip rolls 115 positioned close to a cutter 116.  Chips of cut fibres fall into the lower end of an upwardly inclined trough 118.  A stream of liquid is introduced at high velocity through a nozzle 119 into the lower end of the trough and sweeps the fibres in the chips 117 upwards along the trough and over the lip 121 into a distributing and receiving tank 122.  The flow of liquid in trough 118 initiates the separation from each other of the individual fibres in the chips.  An opening in the floor of tank 122 allows the slurry of fibres and liquid to be discharged on to a wire mesh belt 161, whereby the fibres are separated from the liquid.  Specifications 750,065 [Group I] and 750,067 are also referred to.
