Title: Apparatus for the manufacture of articles by a dipping process
IPC: B29C41/14
Filed: 1941-10-09
Abstract: 558,649. Moulding by dipping. FAIRWEATHER, H. G. C. (Chemical Enterprises Inc.). Oct. 9, 1941, No. 13053. [Class 87 (ii)] The formers are carried by a conveyer through dipping vats, and means are provided for circulating and stirring the congealable liquid in one or several of the vats at a velocity in excess of that of the conveyer travel, whereby more uniform distribution of the liquid on the formers is obtained and rotation of the formers may be omitted. Fig. 5 shows a vat having a pump 53 discharging liquid thereinto at 54 and withdrawing liquid therefrom at 55, the formers 52 passing from left to right. Fig. 6 shows a vat having propellers 56 disposed between two lines of advancing formers 58. The formers are carried by an endless conveyer 10 having one or two chains. Cradles 61 extend between the two chains (or from the one chain), each cradle supporting two formers. Each former is pivoted at 65 in the cradle, and a roller 76, coacting with a track 75, determines the (vertical or horizontal )disposition of the former. The lower reach of the chains passes to the right on Figs. 1 and 1a. The formers dip successively into three latex vats 15 (one of which is not shown) then into a tank 18 in which the dipped articles are washed, and loosened on the formers, then through a tank (not shown) containing talc or mica paste, after which stripping brushes 44 remove the articles. The formers are brushed and rinsed in tank 20. At intervals along the conveyer, e.g. between each pair of dipping tanks, are disposed drying tunnels 25, 27, 29 which dry successive deposits and dry the formers after the articles have been removed therefrom. A fan 26 is disposed on top of each tunnel and blows air against the advancing formers. The conveyer is doubled back upon itself at various points, to save space. Between the last drying tunnel and a curing tunnel 40 is disposed a pair of brushes 41 which roll beads on the articles (see Specification 558,677).

Title: Pipe connection
IPC: F16L27/08
Filed: 1932-05-06
Abstract: 392,734. Pipe joints. LENZE, A., 8, Baumeisterstrasse, Karlsruhe, Baden, Ger. many. May 6, 1932, No. 13125. [Class 99 (i).] In a pipe connection for use in rigid pipe lines having thick walls, pipe ends of elliptic cross section are provided with circular fitting surfaces which lie at the angle to the longitudinal axis of the pipe ends at which the cross section of the end is circular. A short straight pipe length 1 is of circular section at one end, where it is provided with a flange 3 perpendicular to the longitudinal axis of the tube, and its section merges into an elliptical form at its other end 6 where a flange is disposed obliquely to the longitudinal axis to produce a circular section in the tube in the plane of the flange ; two such tubes are joined together at their oblique flanges by circular plates 9, 10 to form an angle piece or bend the inclination of which is adjustable by rotating the flanges relatively to one another. Short intermediate tubes 14, Fig. 4, of elliptical section and provided at both ends with oblique flanges 16, 17 may be interposed between the tubes 13, 15 to increase the inclination. 11“‹ and 45‹ are mentioned as angles of obliquity. Specification 12717/04, [Class 99, Pipes &c.], is referred to.
Patent GB-131350-A (GB)
IPC: F41A3/62
Abstract: 131,350. Soc. Anon. des Etablissements Delaunay-Belleville. March 20, 1916, [Convention date]. Breech actions, sliding breech-block.-Relates to gas-operated guns of the kind in which co-axial opening and closing springs are simultaneously compressed in the same direction by the movement of a gas-piston. According to the invention, the piston moves forwards to compress the springs, so that the forces acting' during the discharge tend to keep the breech closed. In the construction shown, the piston 4 is driven forwards by the gases thereby compressing the opening-spring 9 and the closing-spring 10, which are arranged co-axially on the piston-rod 5, C. At the end of the forward movement, the piston-rod is coupled by means of a pawl 19, Fig. 2, to a sliding tube 12 connected to the bolt-operating sleeve 15. When the gas pressure drops, the opening- spring 9 reacts and drives back the piston-rod 5, 6 and the tube 12 thus opening the breech. The pawl 19 is then disengaged by meeting an inclined surface 22 on a stationary guide rod 13, and the closing spring, acting on a bracket 7 integral with the sliding tube 12, closes the breech. Specifications 137,642 and 131,042 are referred to.
Patent GB-474911-A (GB)
Title: Improvements in or relating to the manufacture of half-tone screen negatives or positives for photo-mechanical printing processes
IPC: G03F5/00
Filed: 1936-05-09
Abstract: 474,911. Photo-mechanical printing- surfaces. KODAK, Ltd. May 9, 1936, No. 13164. Convention date, May 21, 1935. Drawings to Specification. [Class 98 (ii)] A sensitive element for preparing reliefprinting plates comprises a support bearing one or more sensitive layers, one layer, or a stratum of a single layer where only one is used, having formed therein a latent screen image of dots of uniform size and density but each graded in density from a maximum at the centre to a minimum at the periphery. A continuous tone image is subsequently recorded in another layer or stratum. The dot image may be recorded in the upper stratum of a single layer, the continuous-tone image being printed through the support, which may be coloured to limit the penetration of the light. Alternatively the emulsion may be coloured with a dye which is removed in the processing. In place of a single layer, two superimposed layers or two layers arranged on opposite sides of the support may be used. The emulsion layers may be sensitized to different regions of the spectrum, e.g. one to green and the other to red or infra-red, printing being effected with appropriate lights. In one example, a yellow dyed silver halide emulsion of low gamma coated on a support of cellulose nitrate is exposed through the support to a 65-line screen spaced from the emulsion. The emulsion side is then exposed in a contact printing frame to a negative of the subject. The resulting film is developed in a solution of metol, hydroquinone, sodium sulphite, sodium carbonate and potassium bromide and the positive formed is then printed by contact through the support onto a film having an emulsion of high gamma and the resulting negative developed with a solution of trioxymethylene, hydroquinone, sodium sulphite, sodium metabisulphite, boric acid, and potassium bromide. The material may also be exposed in a camera.

Patent GB-570966-A (GB)
Title: Improvements in or relating to electric potential-dividing arrangements
IPC: H01G4/40
Filed: 1943-08-16
Abstract: 570,966. Potential dividers. WHITE, E. L. C., JOHNSON, L. R. J., and NIND, E. A. Aug. 16, 1943. No. 13240. [Class 40 (iii)] A potential-divider is provided with shunt capacities C1 ... CN so related to the resistance sections and to the stray capacities that if the assemblage could be separated into a purely resistive and a purely capacitive network, the voltage would be divided in the same ratio at corresponding points of the two'networks. An example is given of an arrangement in which the resistances are equal and a method of calculation of the resistances when the. capacities are equal. Fig. 4 shows a method of construction, the impedance elements being connected to rings on an insulating rod and surrounded by a shield 22. An alternative divider is shown in Fig. 5. Here each tapping point of the resistive divider is connected to the tapping point of a separate capacitive divider which divides the voltage in the same ratio as the resistive divider at that point. The resistances may have separate shields, each connected to one end of its resistance, the shields being fitted to insulating separators to give a rod-like structure. In a further arrangement, Fig. 7, the shield 31 provides one plate for each of the two potential dividing condensers, the other being shown at 34, 35.

Title: Improvements in electrical circuit breakers
IPC: H01H9/38
Filed: 1959-04-18
Abstract: 910,268. Automatic circuit-breakers. WHIPP & BOURNE Ltd., and STOBART, L. W. July 14, 1960 [April 18, 1959], No. 13279/59. Class 38 (5). An air circuit-breaker comprises an operating lever 31, a first linkage system 22, 24, 26, 28 connecting the lever to a moving arcing contact 16 for closing and holding the arcing contacts 15, 16 closed, a second linkage system 37, 40, 41, 44, 46, 47 connecting the lever to a moving main contact 10 for closing and holding the main contacts closed, a trip mechanism 51, 52, 55 for rendering the second linkage ineffective to hold the main contacts closed and means 57, 58 responsive to a predetermined opening movement of the main contacts for releasing the first linkage system to open the arcing contacts. To open the circuit-breaker from the closed position shown in Fig. 1, a trip lever 55 is turned so permitting a toggle 51, 52 to collapse and permit a toggle 46, 47 of the second linkage system to collapse so that a spring 65 opens the main contacts 10, 14. During the initial part of the opening movement, the pivoting of the arm 11 carrying the main moving contact increases the pressure between the arcing contacts. When the second linkage system reaches the position shown in Fig. 2, the end of a slot in a link 57 connected to the toggle 46, 47 abuts a pin 58 on a strut 28 of the first linkage system so that as the opening movement of the second linkage system continues, the strut 28 is moved. This disengages a hook 30 from the end of the operating lever 31 and permits a spring 64 to open the arcing contacts. At the same time, an abutment 61 on an extension 60 of the toggle link 47 moves a prop 59 to release the operating lever 31 which then moves into its open position, Fig. 3, where the hook 30 re-engages the end of the lever, the toggles 46, 47 and 51, 52 being reset. The operating lever 31 may be operated by hand or by a solenoid 36 to close the circuitbreaker.

Title: Improvements relating to take-up mechanism for receiving long lengths of material on reels, drums or the like
IPC: B65H54/28
Filed: 1936-05-11
Abstract: 472,189. Winding. HENLEY EXTRUSION MACHINE CO., Ltd., and DUNSHEATH, P. May 11, 1936, No. 13354. [Class 83 (iv)] In a winding device for an extrusion machine, the speed of rotation of the winding drum is controlled by a differential device driven by the work and the winding drum. An extruded pipe 1 drives a pulley 12 carrying a pinion 7. The winding drum drives a pinion 8. A pinion 15 meshes with pinions 7, 8 and is mounted on a spider 16 carrying a switch arm 75. When the winding drum and the material are travelling at the same speed, the spider is stationary but when they are unequal the spider and arm 75 are tilted. The arm 75 then rocks a support 81 carrying mercury switches 85, 86 controlling relay switches 99, 100, Fig. 11, in circuit with a reversible pilot motor 98 controlling a resistance 94 in the field on an electromotor 91 driving the winding drum. The pinion 8 may be driven through a change speed gear from the shaft of the winding drum or from a roller contacting the wound up material. In a modification, Figs. 12, 13 (not shown), one of the gears drives a pair of light sensitive cells and a source of light for each cell and the other gear drives an interposed shutter. Relative rotation of the cells and shutter exposes one or other of the cells and actuates a relay for altering the speed of the winding drum.

Abstract: 930,410. Sampling ores &c. RHOANGLO MINE SERVICES Ltd. April 14, 1961 [April 21, 1960], No. 13482/61. Class 58. Apparatus for automatically sampling comminuted ores &e. discharged, as a falling stream, from a travelling conveyer belt 10 through a shoot 11, comprises a vertical circular plate 12 centrally secured to a horizontal shaft 13 rotated, through gears by a motor 17. Primary and secondary sampling scoops 21 and 22 are pivotally carried by the plate so that they are disposed vertically, with their open mouths uppermost, as it is rotated. The primary scoop 21 has a base 24 in the form of a swinging arcgate closing by gravity and two inclined side walls 25. The capacity and the size of the mouth of the scoop 21 can be varied by moving one of the walls 25. The secondary scoop 22 is in the form of an elongated cylinder having a closed base and an adjustable mouth and it can be detached from the plate 12. The scoop 21 passes through the falling stream and collects a primary sample and then passes over a hopper 27 having projections 28, which open the arc-gate and discharge the primary sample on to an upper travelling conveyer belt 26, from which it is discharged as a second falling stream. The scoop 22 passes through this stream and collects a secondary sample. The speeds of the plate 12 and belt 26 may be regulated, mutually, so that one primary sample is completely discharged from the belt before another is deposited thereon. A magnetic clutch and brake, controlled by time and trip switches (not shown), may be provided, in the drive from the motor 17, so that the plate 12 may be rotated intermittently.

Title: Process for improving the wear-resistance of textile materials
IPC: D06M15/263
Filed: 1939-01-13
Abstract: 527,761. Treating textiles with liquids. TOOTAL BROADHURST LEE CO., Ltd., CORTEEN, H., FOULDS, R. P., POTTER, H., and BATTYE, A. E. Jan. 13, 1939, Nos. 10442/39, 13603/40, 13604/40, and 13605/40. Divided out of 527,762. [Class 15 (ii)] The wear resistance of textile materials is increased by impregnating them with a solution or dispersion of a synthetic rubber-like material which is resistant to discolouration on exposure to air and also with synthetic resin components or an intermediate condensation product thereof applied during or after impregnation with the rubber-like material, and insolubilizing the resin by heat, the resin being present in a smaller proportion by weight than the rubberlike material. The rubber-like material may be polymerized vinyl acetylene, butadiene, or isobutylene, or a polyacrylic or polymethacrylic ester, polyvinyl acetate or chloride, polyvinyl alcohol, a polyvinyl ether or acetal, or polystyrene. Polymerized chlor-butadiene, which tends to become discoloured on exposure to air, is excluded. The polymer may be used in aqueous dispersion or in an organic solvent. The synthetic resin may be a urea-formaldehyde, phenol-formaldehyde or glycerine-phthalic anhydride resin. The presence of the synthetic resin counteracts the tendency of any wax, fat, or oil, in the textile materials to prevent the rubber-like material from, imparting the desired increase in wear-resistance. The synthetic resin may be present in sufficient proportion to impart resistance to creasing. The treated textile materials may be further treated with cellulose ethers. In an example, cotton fabric is impregnated with an aqueous solution containing "Igeplast" E (Registered Trade Mark) emulsion, and "Bedafin" (Registered Trade Mark) which is a glycerine - phthalic anhydride - urea - formaldehyde resin, rendered soluble in water by adding a little triethanolamine. The fabric is squeezed so that it retains about its own weight of liquor. It is dried and then heated to insolubilize the resin. The fabric is boiled in a solution of soap and sodium carbonate. In another example, a linen fabric is impregnated with an aqueous emulsion containing "Igeplast" E (an alkyl alkacrylate). It is dried and then passed through a solution containing an intermediate condensation product of urea and formaldehyde with tartaric acid as catalyst. The fabric is dried and then heated to insolubilize the resin. It is boiled in a solution of sodium carbonate containing a wetting agent. It is treated with caustic soda solution and allowed to shrink in warp and weft. The fabric is crease-resisting and has a high wear-resistance. Specifications 486,926 and 527,762 are referred to.
