Title: Improvements in or relating to the manufacture of insulating slabs
Inventor: HEINRICH ALFRED REINHARD
IPC: C04B20/10
Filed: 1964-08-14
Abstract: Insulating slabs are made by treating or impregnating wood wool with fungicidal, insecticidal or bactericidal substances, mixing with cement, magnesite, lime, or gypsum, and moulding or pressing.  Before moulding or pressing, the wood wool is treated with an aqueous emulsion of polyvinyl propionate or acetate, so that after moulding or pressing the wood-wool fibres are covered with a film of polyvinyl propionate or acetate.  The film confines within the fibres the substances with which the wood-wool was treated or impregnated.  The wood-wool may be treated with, e.g. CaCl2, MgCl2, lime water, sodium or potassium silicate, or sodium pentachlorphenolate. A foam, e.g. foamed polystyrol, may be admixed with the wood wool before moulding. The mould may be lined with a hessian cloth soaked in a preservative solution, which becomes incorporated in the finished slab.  Wooden lathes may also be incorporated in the slab.  The slab may subsequently be coated with e.g. methyl cellulose, bitumen, or polyvinyl acetate or propionate which may be mixed with lime or cement.ALSO:Insulating slabs are made by treating or impregnating wood wool with fungicidal, insecticidal or bactericidal substances, mixing with cement, magnesite, lime, or gypsum, and moulding or pressing.

Title: Improved apparatus for delivering measured quantities of liquids
IPC: B67D7/16
Filed: 1922-12-05
Abstract: 191,011. Gueux, J. J. M. Dec. 28, 1921, [Convention date]. Fixed-chamber apparatus; varying quantity measured in ; valve systems for; with counting and registering apparatus.-Liquid is supplied by pressure, suction or gravity to a glass container through an inlet tube surrounding an overflow pipe, the inlet tube being surrounded by a series of troughs at different levels which allow the liquid to flow into a collector fitted with a single delivery pipe. The liquid is supplied by a pump 21, Fig. 8, through a pipe 20, Fig. 3 to the annular space between the pipes 9, 10, the pipe 10 leading back to the supply tank. The troughs at the levels P<5>, P<10>, p<15>, P<20>, Fig. 1, are connected by pipes 13, 14, 15, 16 through valves as shown in Fig. 5 to a common collector 35 fitted with a single discharge pipe. 37 fitted with a cock 38. Each valve 39 is closed by the pressure of the liquid and springs 42, 43, the latter of which acts as a handle 44 pivoted to a link 45 which carries a counter and the final wheel of which is moved through one tooth when the corresponding valve handle 44 is actuated. The handle is connected to the valve stem 40 by a pin and slot to a spring-pressed pawl 49 con. nected to the link 45 by a pin and slot. Each handle is also connected by linkage to an indicator plate. To deliver say fifteen litres, the valve 22 is opened and the pump actuated until fluid stands at the level P, O. The handle 44 corresponding to the level P" is then moved to open the valve and actuate the counter. This movement of the handle causes the numeral 15 to appear at the window 57, and the handle is locked by engagement of its end with the notch in the leaf spring 59. The level of the liquid in the container sinks to the level P<15> the liquid flowing into the collector 35 from which it is led to discharge by the pipe 37 and cock 38. The quantity delivered is obtained by multiplying the number of actuations of any handle by the valve corresponding to the handle. The container is fitted with a drain pipe and cock leading to the supply tank which cock for cleaning purposes may empty the container completely.

Title: Improvements in electric relays of the flasher type
IPC: B61L5/18
Filed: 1949-12-30
Abstract: 659,390. Electromagnetic interrupters UNION SWITCH & SIGNAL CO. Dec. 30, 1949, No. 33326. Convention date, Jan. 5. [Class 38(v)] In an electromagnetic interrupter suitable for controlling flashing signals, the time of interruption is varied by varying the reluctance in a magnetic circuit that is in parallel with the armature. In the form shown the core 4 which has a central pole piece 3 and two end pole pieces 1, 2 carries two windings 8, 9 which are arranged in series and alternately short-circuited by the movement of the centrally-pivoted armature 13. This is shown diagrammatically by the switch 21. At starting, the armature occupies a position slightly off centre so that both windings are energized but the winding 9 predominates causing the armature to be attracted to the pole piece 2 and short-circuiting winding 9 so that the armature is then attracted by winding 8 to its other position whereupon winding 8 is short-circuited and so on. Short-circuited coils 7 delay the build up or decay of flux and so influence the timing which can be further influenced by adjusting the air gaps between a magnetic plate 10 and extensions of the two pole pieces 1, 2.

IPC: A47L23/02
Filed: 1933-11-30
Abstract: 415,620. Boot-cleaning machines. NORTH, J. M. W., 396, London Road, Isleworth, Middlesex, and TAYLOR, C. H., 42, Finchley Park, North Finchley, London. Nov. 30, 1933, Nos. 33669 and 35008. [Class 138 (i).] A machine for cleaning and polishing boots and shoes comprises a hollow rotatable member having on the inside a cleaning surface and being open at one end to permit the insertion of a boot or shoe, the member being adapted to be rotated by a motor through a friction drive. In the construction shown in Figs. 1 and 2, a casing 10 supports an electric motor 24 adapted to drive, through a friction wheel 26 and an annulus 15, a sleeve 17, in which is fitted a brush carrier 18. A clamping screw 19 locks the carrier in position. A tubular polisher 20 of lambskin is fixed by screws 21 to the inner end of the carrier, and to the outer end an annular brush 23 is detachably secured. The bristles of the brush 23 increase in length from the outer edge inwardly, the shorter bristles being used for cleaning and the stiffer bristles for preliminary polishing purposes, the final polishing being effected by the polisher 20. The outer end of the polisher may be tucked in out of the way when the brush 23 is in use. The motor shaft carries a fan 31' adapted to collect dust from the shoes and deliver it to a dust bag 34, apertures being formed in the polisher 20, carrier 18, and sleeve 17 to facilitate the collection of dust. The motor is mounted about a pivot 28 as shown in Fig. 2, so that its weight keeps the friction wheel 26 in engagement with the annulus 15. The amount of slip between the wheel and annulus may be adjusted at will by means of a leaf spring 29 supported by an adjustable screw 30, the spring acting against the weight of the motor. In a modification shown in Fig. 4, a single brush is used for cleaning and polishing, the bristles 42 increasing in length towards the inner end of the brush body. The fan instead of being on the motor shaft is on the brush structure, fan blades 43 being formed by bent up portions of the sleeve 17. In a further construction shown in Figs. 6 and 7, the brushing members comprise a tubular polisher 20 and an annular brush 54, the stock of which is tapered as shown at 55 to provide longer and more flexible bristles at one end of the brush than at the other. The brush projects partly from a casing formed by side members 44, 45 spaced apart by tubes 46. A tray 49 is provided for collecting dust. To remove surplus polish from the brush two rotatably-mounted wire brushes 57, 58 are provided, one for removing black polish and the other for removing brown polish. Normally these brushes are out of contact with the brush 54, but either can be positioned to engage it by the operation of a knob 60.

Title: Improvements in or relating to multilayer photographic elements
IPC: G03C7/26
Filed: 1945-12-14
Abstract: 605,099. Colour photography. DU PONT DE NEMOURS & CO., E. I. Dec. 14, 1945, No. 33864. Convention date, Dec. 15, 1944. [Class 98 (ii)] A multilayer photographic element comprises a transparent base, at least two lightsensitive silver halide layers superimposed thereon, and between such layers a layer containing a silver salt which does not form a developable image on exposure to light but is rapidly reducible to metallic silver with a developing agent having a reduction potential of at least 0.3. The silver salts are in general water insoluble, they may be coloured or dyed or colourless and the layers containing them may be used as filters or light barriers. An exposed element of this type is developed in a non-colour forming developer, the residual silver halide in one layer is exposed to light and developed in an aromatic primary amino developing agent in the presence of a colour coupler, and the residual silver halide in a further layer, or layers, is similarly processed using different colour couplers. The silver salts may be the ferrocyanide, dichromate, sulphate, thiocyanate, tungstate, arsenate, phosphate or tetraborate and the layers containing them are produced by double decomposition from solutions of silver nitrate, or ammoniacal silver nitrate, and gelatin with the corresponding alkali salt, followed by chilling, washing, and the usual procedure as in the manufacture of gelatin-halide emulsion layers. Silver chromate, ferricyanide, arsenite, tartrate, citrate or oxalate may also be used. Three examples describe production of the multilayer element and its processing to yield multi-colour positive film, and tables compare the density of the silver salt layers and that of fogged silver halide layers when read against light of different colours. The layers are adaptable to use in the preparation of stripping films for colour print processes. Numerous developers and colour couplers are mentioned. Specifications 354,898, 458,664, 483,548, 497,463, 497,698, 505,099, 512,542, 512,563, 535,341, 537,232, 541,558, 542,904 and 543,290 are referred to.

Title: Improvements in wool scouring machines
Inventor: BOWE MAURICE THOMAS
IPC: D01B3/08
Filed: 1963-08-28
Abstract: 1,011,360. Textile treating apparatus. PETRIE & McNaught Ltd. Aug. 24, 1964 [Aug. 28, 1963], No. 33999/63. Heading D1L. Means for moving loose fibrous material through liquors in a washing machine comprises a plurality of paddles 3 carried by reciprocable carriers 8 and means for holding the paddles 3 vertical during forward travel and horizontal during backward travel, each paddle 3 having a perforated leading face and a back plate 35 arranged to allow liquid to flow out of the paddle during forward movement while preventing liquid from entering the paddle 3 during its retraction. The material, e.g. wool, cotton or man-made fibres, is supplied by a conveyer 2 to a scouring tank 1 containing liquor to the level 4. The paddles 3 convey the material through the tank 1 and it is discharged by a harrow 7 to squeeze rollers 6. Each paddle 3 is attached by webs 5 to a rod 10 rotatably mounted in the carriers 8 which are slidable longitudinally on rollers 18 in brackets 24 attached to the tank 1. A rod 17 is connected by arms 14 to the rods 10 to effect simultaneous rotation thereof. The piston rod 13 of a cylinder 11 mounted on the carriers 8 by brackets 12 is connected to one of the arms 14, the stroke of the rod 13 being such that it turns the paddles 3 through 90 degrees between its fully retracted and fully extended positions. The carrier 8 operates trip switches 27, 28 at opposite ends of its travel which switches are connected between electricity supply terminals and solenoids 31, 31a operating pilot valves 32a, 32b to control a valve 32 controlling the air supply to the cylinder 11. The piston rod 21 of a pneumatic cylinder 19 carried by brackets 20 on the tank 1 is attached to a member 22 connecting the carriers 8 together. The cylinder 19 incorporates electric switches 33, 34, Fig. 5 (not shown), closed by the piston at the ends of its travel and which are connected between electricity supply terminals and solenoids 26, 26a operating pilot valves 25a, 25b to control a valve 25 controlling the air supply to the cylinder 19. The fibrous material is conveyed through the tank 1 by the paddles 3 moving to the right of Fig. 1 while in a vertical position. The back plate 35 of each paddle swings backwards as the paddle moves forwards to allow liquor to pass through. Towards the end of their movement to the right the cylinder 11 moves the paddles 3 through 90 degrees and out of the liquor to the position 3a, Fig. 4. The paddles 3, while still horizontal, are then retracted to the position 3b and are turned back through 90 degrees ready to move to the right again. An electric and pneumatic circuit diagram for the apparatus is shown in the specification. In modifications (not shown) the carriers 8 may be driven by a crank and a sliding connecting rod and the mechanism for retracting and lowering the paddles 3 may be operated by a composite internal and external cam and chain drive.
