Abstract: 559,693. Plaster bandages. SMITH & NEPHEW, Ltd., T. J., and BURLEY, D. W. Aug. 25, 1942, No. 11947. [Class 81 (ii)] A plaster bandage for surgical purposes is prepared from a paste of unburnt gypsum, an absorptive material, an adhesive and water, the paste being spread on a carrier of textile fabric &c. and subjected to heat in an oven to convert the gypsum to plaster of Paris. Suitable absorptive materials are activated charcoal, kaolin, fullers earth and magenisum trisilicate. The adhesive is soluble or swellable in water e.g. dextrine, gelatine, gum acacia, gum tragacanth or certain cellulose ethers. The rate of travel of the paste-coated fabric through the oven and the temperature thecrof may be varied to produce a plaster which, after wetting, will set in from five to ten minutes. The inlet temperature of the oven is preferably 180‹-250‹ C. and the outlet temperature 120‹-140‹ C. In an example 12¢ parts by weight of fullers earth were added to 87¢ parts of unburnt gypsum and mixed to a dough with water. Then ¢ to 5 parts of dextrine, mixed with water to form a jelly, was added to the dough and further water added to give a paste of the required consistency. Specification 483,636 is referred to.

IPC: F41A27/02
Filed: 1936-04-27
Abstract: 474,293. Gun control. EVERSHED & VIGNOLES, Ltd., and SHORT, W. J. April 27, 1936, Nos. 11984/36 and 10664/37. [Class 92 (i)] Relates to model-switch endangering-preventing apparatus for superposed turrets A, B, Fig. 1, having endangering and endangered elevation contacts e, f and corresponding training contacts s, t as described for example in Specification 15487/09, [Class 92 (i)]. According to the present invention, mechanism actuated by the training movement of either or both turrets, such as a cam gear k, d, causes relative sliding movement of the contacts e, f so that a warning circuit through a trumpet T is completed if, as the result of training movement alone, the guns are brought into a dangerous position. Further, compensating mechanism, such as a crank p, slider q and sector gear. r, is actuated by the elevation of an endangered gun to cause relative movement of the training contacts to allow for the foreshortening effect in the path of training, as seen in plan, when the gun is elevated. Fig. 3 shows a modification of the endangering and endangered elevation contacts e, f which has for its object to spread fanwise the effective area of such contacts when there are say four independently elevatable guns in the endangering and endangered turrets. The contact e comprises a forked part e' moving about a shaft 13, and a sector part e<4> moving within the fork about a shaft 14. The shafts 13, 14 each carry four stops w<3>, x<3> respectively which are moved by four motors Ea3 rotating in synchronism with motors actuated by the elevation of the guns in the endangering turret. The contact parts e<2>, e<4> are positioned respectively to suit the guns of lowest and highest elevation by means of bars R<2>, P<2> which engage the appropriate stops. Similarly the parts f<3>, f<4> of the endangered contacts are respectively positioned by similar stop gear M, N to suit the guns of lowest and highest elevation in the endangered turret.

Title: Methods of and apparatus for electrically removing entrained particles from gas streams
IPC: B03C3/40
Filed: 1932-04-26
Abstract: <PICT:0383547/III/1> <PICT:0383547/III/2> <PICT:0383547/III/3> <PICT:0383547/III/4> <PICT:0383547/III/5> <PICT:0383547/III/6> <PICT:0383547/III/7> In a process for the electrical separation of suspended particles from gases, alternate fields of high and low concentration are established between the discharge and collecting electrodes, the latter being maintained at a uniform potential, and the field of high concentration is maintained in a substantially uniform condition, for example by cleaning the electrodes.  In the arrangement shown in Fig. 1, the collecting electrodes consist of plates 2 spaced apart to clear the pipes or rods 3 which project into the gas passages to form the terminals of the highly concentrated field.  Half-round bars or pipes 3<1> are similarly arranged adjacent the side walls of the casing 1 which also act as collecting electrodes.  These bar-type electrodes are arranged opposite the discharge electrodes 10, and their upper ends slide in glands 4 and have anvil-heads 5 supported by springs 6 (see Fig. 4).  The lower ends are flattened and secured in a channel into which the lower edges of plates 2 also extend.  They may be made of metal or of asbestos cement composition, concrete or other semi-conducting material, and are cleaned by hammers 15 actuated by rocker shafts 14. The plates 2 may be cleaned less frequently and if required by hammers 32, operated by shafts 31, striking the anvils 33.  The electrodes 3 may also be cleaned by rotation against spring-pressed scrapers 16, Fig. 6 or brushes 17, Fig. 7.  In cases where the necessary electrical conditions cannot be maintained by these methods, the electrode surfaces are flushed with washing liquids as shown in Fig. 8, a stream of low pressure water being delivered by a pipe 19 to the interior of the electrode 3a.  The water spills over and forms a film down the outside of the electrode.  This arrangement is particularly useful where it is desired to conserve the heat content of hot gases.  The application of the process to a precipitator in which the main collecting electrodes 23 are corrugated is shown in Fig. 11, the subsidiary collecting electrodes 25 being opposite the discharge electrodes.  An arrangement for a pipe treater is shown in Fig. 12.  The field between the discharge electrodes and the subsidiary portions of the collecting electrode is maintained as near as possible to the value at which a sparkover would occur if the electrode surfaces were free from deposits.  Any deposit on the discharge electrodes may be removed by known means.

Abstract: 1,255,217. Hydrostatic transmission; variable speed gear. SOC. ANON. FRANCAISE DU FERODO. 6 March, 1969 [8 March, 1968], No. 12011/69. Headings F2C and F2D. A hydrostatic transmission comprises a rotary valve plate 12 between internal gear type fixed displacement pump and motor units 11, 11<SP>1</SP> arranged with a plane S separating the pump suction and delivery chambers 23 inclined to a plane (S<SP>1</SP>) separating the motor suction and delivery chambers. The pump and motor each comprise an inner lobed wheel 20a fast with the input or output shaft 10, 10<SP>1</SP> and an outer lobed wheel 20b freely rotatable in an eccentric ring 21 fast with a housing 14. The chambers 23 formed between the wheels 20a, 20b communicate with arcuate ducts 30, 31 formed in the valve plate 12. The valve plate 12 is rotated by supplying pressure liquid to one side or the other of projections 46, 47 fast with the plate 12. A pump 58 supplies pressure liquid through a manual or output speed responsive control valve 53 to chambers 48, 49 for clockwise speed increasing rotation of the plate 12 and supplies pressure liquid to chambers 61, 62 for anticlockwise speed decreasing rotation of the plate 12. The plate 12 is additionally biased by springs 13 to the minimum speed position. The planes S, (S<SP>1</SP>) are preferably inclined at 90 degrees to each other and in the minimum output speed position of the plate 12 the ducts 30, 31 are divided approximately centrally by the pump plane S for minimum pump output whilst the motor plane (S<SP>1</SP>) lies between the ducts 30, 31 for maximum motor capacity. As the valve plate 12 rotates the pump output increases whilst the motor capacity decreases. A make-up pump (70) supplies liquid through a line 72 and one-way valves 73, 74 to the low pressure ducts 30 or 31. High pressure relief valves 76, 77 are provided. A by-pass valve 110 interconnects the duets 30, 31 for neutral. The rotors of the pump and motor are maintained in contact with the valve plate 12 by spring pressed rings 19, 19<SP>1</SP>. In Fig. 9 (not shown) a hydromechanical gear comprises output carried planet pinions (102) meshing an input sun gear (101) and a reaction ring gear (104) connected to the input through a hydrostatic transmission of the type described above. The ring gear (104) is fast with a rotatable casing (14) of the hydrostatic gear which has a pump rotor (20a) fast with an input shaft (10) whilst the motor rotor (20a 1 ) is fixed to an outer casing (106). -An additional planet pinion (109) meshes a sun (108) which may be held by a brake (107) for reverse drive.

Title: Storage tube
IPC: H01J31/62
Filed: 1949-05-09
Abstract: 709,554. Cathode-ray tubes. CLARK, G. M. (Radio Corporation of America). May 9, 1949, No. 12338/49. Class 39(1) A storage tube has two electron beams, one of low velocity for scanning a target comprising a film of insulating material on a conductive plate and the other of high velocity for inducing conductivity in the film at the point of impact. The material may be silica formed by precipitating from ethyl silicate vapour, magnesium fluoride, aluminium oxide or high resistance glass. Formulae for determining the thickness for maximum penetration are discussed. The target may comprise a copper mesh screen upon which the insulating film is formed by first stretching a temporary film of collodion across the mesh and evaporating on the layers of aluminium and insulating material e.g. magnesium fluoride. The collodion is dispersed by baking. An alternative target comprises a heavy metal plate e.g. nichrome carrying the thin dielectric film. In Fig. 1, the writing gun 20 produces a beam of high velocity modulated by incoming signals on the control electrodes, and this beam scanning the target 40 makes the insulating layer 44 conductive allowing passage of current from the negatively charged signal plate. A negative charge pattern is laid down by the writing gun on the surface 44, the scanning preferably being spiral. The reading gun 30 gives a low velocity beam producing secondary emission greater than unity at the surface 44 and removes the charge pattern laid down by gun 20 to produce signal pulses in the output circuit of the signal plate 42: The secondary electrons are collected by the wall coating 24. In a modification, the two guns are symmetrically mounted with respect to the axis of the tube the target being at right angles to the writing gun. In a further modification, Fig. 4, (not shown), the guns are on opposite sides of the target. The scanning patterns and cyclic rates of the writing and reading beams may be different. The potential gradient across the insulating film at equilibrium potential may be a million volts per cm. Reference has been directed by the Comptroller to Specification 668,727.
