Title: Improvements in and relating to the method of operation of oxygen breathing apparatus with regeneration of the breathing air
IPC: A62B7/00
Filed: 1949-06-17
Abstract: 663,967. Respiratory appliances. DRAGER, O. H. June 17, 1949 [Dec. 15, 1948], No. 16152/49. Class 81 (ii) In a closed circuit regenerative breathing apparatus, air is withdrawn from the system at a rate dependent on the rate of introduction of oxygen. In one embodiment air is taken from a breathing bag 4 through a tube 14 and returned through a tube 16. When the available volume of air becomes reduced the collapse of the bag 4 opens a valve 9 by means of a lever 17, to admit oxygen from a pressure reducing valve. This oxygen builds up a pressure in the lower chamber of a central device 13, owing to the outlet being reduced by a choke, and thereby raises the associated diaphragm to expel the air in the upper chamber through an outlet 20. As the oxygen escapes into the system the diaphragm is forced down by the coil spring in the upper chamber and withdraws a quantity of air from the breathing circuit. The strength of the spring is such that the ratio of volume of incoming oxygen to outgoing air is correct for normal purposes, and is suggested as 100 : 5. A modified form of the appliance, in which the diaphragm pump is combined with the lung-operated valve and connected upstream thereof, is described with reference to Figs. 4 and 5 (not shown).

Abstract: 594,107. Drilling. BRITISH TABULATING MACHINE CO., Ltd., and VINES, W. C. June 26, 1945, No. 16302. [Class 83 (iii)] In a drilling machinewith automatic devices for bringing and registering work-pieces into position to be drilled, clamping them during drilling and ejecting them after drilling, the automatic devices are operated electrically by contacts operated by cams on a slow speed shaft driven from the drilling spindle and mechanically connected to the feeding means of the drill. The drill spindle 1 has a pulley 5 and gear-wheel 4 splined to its upper end and is journalled in a sleeve 2 reciprocable in a guide 3 of the frame by means of a rack 6 and a pinion 7 on a shaft 8. A cam 13, on a slowspeed shaft 14 driven from the gear-wheel 4 by reduction gearing 15, 17, 18, 20, 21, feeds the drill up and down by means of a spring-returned rack bar 11 and another pinion on the shaft 8. The slow-speed shaft also carries three cams for operating contacts in the electrical circuit. The work-pieces, such as terminal posts 43, are fitted in holes 47 and scallops 48 in a plate 41 fixed to an indexable table 27 provided with ratchet teeth 29. A ratchet 30 engages the teeth 29 and is reciprocated by the plunger 32 of a solenoid 34 ; a plunger stop 38 and locking stop 40 are provided. For holding a circular work-piece against rotation and for registering it correctly at the drilling station 45, a lever 51 is pressed against the work-piece by the 'energizing of an electromagnet 53. If the work-pieces are held against rotation by reason of their form, the lever 51 is employed only for registering, being given a V-shaped end engaging notches in the plate 41. A stop 54 is provided for the lever. The drilled workpieces are ejected by a lever 59 engaging under the shoulder of the work-piece and tilted when an electromagnet 57 is energized ; a stop 61 is provided. If the work-pieces are of a size larger than the pitch of the teeth 29, the cam for the solenoid 34 may be shaped to energize it twice in rapid succession, so rotating the table by the pitch of two teeth at each operation.

A holder for bottles to be stoppered in vacuo comprises a base 1 and a vertically-reciprocable plate 2 having apertures fitting the bottles, the stoppers 5 being frictionally supported in sleeves 4 of such size that they can slide over the bottles and yet be supported by the plate 2. In operation, each filled bottle is stoppered and fitted with a sleeve 4 and the plate 2 is raised manually or otherwise, being retained in raised position by a stop. A bottle is then inserted in each aperture in plate 2, the bottles being suspended by the sleeves. The holder is inserted in a vacuum chamber and, upon evacuation, the pressure inside the bottles drives out the stoppers and the bottles drop on to base 1 being still engaged by plate 2. Dehydration or freeze-drying is then effected and the stop holding plate 2 is released by remote control so that the plate, the sleeves 4 and the stoppers drop, the latter sealing in the bottles. Upon breaking the vacuum in the chamber, ambient pressure forces the stoppers home and the sleeves are removed.

Abstract: Artificial threads produced by the wet-spinning process are collected free from kinks and curls, by loosely suspending the reciprocating funnel through which the threads pass into a centrifugal spinning box, by a support situated approximately in the same horizontal plane as the centre of gravity of the funnel. A ring or collar may be attached to the funnel or its effective length may be increased, in order to adjust its centre of gravity to any desired position.  The spinning funnel 1, Fig. 1, having constrictions 3 is loosely supported on the metal ring 7 attached to reciprocating support 9.  A heavy metal ring 10 is attached to the top of funnel 1 so that the centre of gravity of the funnel lies approximately in the same horizontal plane as the ring 7. The lower end of the funnel 1 terminates within centrifugal spinning box 4.  In a modification, <PICT:0570618/IV/1> <PICT:0570618/IV/2> Fig. 2, the funnel 1 is provided with a metallic collar 11 having a lower hemispherical portion 12.

Abstract: 500,798. Colour photography; finishing processes. STOCK, F. J. J. June 12, 1937, No. 16401. Drawings to Specification. [Class 98 (ii)] Subtractive colour films produced on multilayer silver-sensitive films in which the image layers are separated from one another and from the support by plain layers as of gelatine, and from which the silver or silver salt images are removed after the production therefrom of dyestuff images, are caused to exhibit improved colour rendering by treatment with a liquid capable of dialysing through the image layers, and of swelling and dissolving the material of the separating layers in order to redistribute this material in the hollows left in the image layers by the removal of the grains of silver or silver halide after colour processing, the liquid being of neutral or slightly acid reaction and such as will not injure the dyestuff images. The liquid may contain dissolved solid. substances of appropriate refractive index, such as gelatine or agar-agar, to assist in filling up the hollows ; and it may contain colloids of greater strength than the image layers, e.g. acetyl cellulose, to produce a hardened surface, or such surface may be produced by an aftertreatment. The liquid may consist of swelling agents such as ammonium acetate, ammonium or sodium salicyl, benzol-sulpho-acid, or chloral hydrate in aqueous or alcoholic solution, and dissolving agents such as a chlorinated aliphatic alcohol and non-chlorinated aliphatic alcohols or their derivatives. It may also include water-soluble esters of high boiling point such as lactic acid ester or diacetone alcohol to prevent shrinking. A preferred mixture comprises aqueous sodium salicyl solution ; chlorinated ethyl alcohol ; arnyl, ethyl and methyl alcohols ; lactic acid ethyl ester ; and triacetin. Primary acetyl cellulose or triacetyl cellulose may be dissolved in this mixture, or the film may be subsequently treated with a liquid containing such material and methylene chloride, chlorinated ethyl alcohol and water. The liquid may also contain a wetting-agent.

Abstract: 642,223. Indicating liquid-levels. COMPAGNIE FRANCAISE DE RAFFINAGE. June 18, 1948, No. 16497. Convention date, June 23, 1947. [Class 123(i)] A method of gauging the water level in the bottom of a tank T containing a liquid less dense than water comprises withdrawing liquid from the bottom of the tank by means of a movable member, e.g. a tube 3, which is raised until water ceases to be discharged from the tube 3 and is replaced by the liquid, the position of the tube 3 being then noted. The tube 3 which is enclosed in a cylinder 1 provided with a stuffing box 4, is raised by rotating a nut 13 mounted in a bracket 15 and engaging the threaded part 12 of the tube 3. Upon opening a cock 7 on the tube 3 water is siphoned out of the tank T, and the tube 3 is then adjusted as described above, its final position being indicated by a pointer 5 cooperating with a scale 6. In one modification the cock 7 is replaced by a port in the tube 3, the port lying below the stuffing box 4 and hence being closed when the tube 3 is in the lowest position. Alternatively the cylinder 1 may be closed when the tube 3 is in its highest position, either by a valve formed on the end of the tube 3, or by a separate valve.
