Abstract: 745,369. Mixing appliances; pug mills. BRITISH CERAMIC RESEARCH ASSOCIATION. Nov. 24, 1953 [Nov. 24, 1952], No. 29588/52. Class 86. A system for controlling the addition of water to plastic clay flowing in a conduit, consists of a flexible diaphragm arranged in the wall of the conduit susceptible to the pressure of the clay which will vary according to the consistency of the clay due to the restriction constituted by a die or outlet, the diaphragm being operatively connected with a valve which controls the addition of the water. A pressure responsive unit 2 containing the flexible diaphragm, Fig. 2 (not shown), is provided in the wall at the die end portion of a pug mill 1. The flexible diaphragm acts upon a bellows in the pressure unit 2 which is connected to a capillary tube 3 containing hydraulic fluid which transmits to a second bellows in a control valve 4, the pressure of the clay passing through the die of the pug mill. The valve 4 controls the supply of liquid from a constant head supply 7 to a number of centrifugal spray nozzles 6 which may discharge into a mixer disposed at the inlet end of the pug mill. To avoid hunting by the system, the water supply by way of the nozzle 6 may be only an auxiliary supply, the main supply not being subject to the control system. The conduit 1 may be a by-pass, containing an auxiliary auger instead of a main pug mill. The controlled auxiliary water supply may be fed into the mixer preceding the auxiliary auger or into a second mixer or smooth rolls which follow the auxiliary auger, or into the feed box of the main pug mill.

Title: Improvements in or relating to impermeable cloth
IPC: B64B1/58
Filed: 1930-10-03
Abstract: Fabric for balloons is made by coating fabric with a mixture of viscose and rubber, and regenerating cellulose by exposing the coated material to an acid gas such as sulphur dioxide or acetic acid gas. Glycerine is added to a viscose solution, and then rubber latex to make a mixture the solids of which are 70 per cent viscose and 30 per cent rubber, with glycerine equal to 5 per cent of the viscose. Preferably the fabric is first coated with a rubber composition, and sized with an adhesive such as gelatine or glue.  A number of coats of the viscose-latex mixture are then spread on, each coat being dried.  The material is then festooned in a chamber in which it is exposed to sulphur dioxide at atmospheric temperature for about 30 minutes.  The chamber is then emptied of gas, and ammonia introduced to neutralize free acid. The method of regeneration may be applied to any process in which cellulose xanthate or viscose is regenerated.

Title: Apparatus for testing hollow objects
IPC: G01M3/36
Filed: 1975-07-15
Abstract: 1456959 Pressure and crush testing hollow objects CARNAUD TOTAL INTERPLASTIC 15 July 1975 [16 July 1974] 29729/75 Heading G1M A bottle inspection device which checks for leaks and resistance to crushing comprises, a sealing ring 34 which is initially held down on the bottle top 12 by a weak spring 32 to seal the gasket 29 and the bottle mouth 30 and later is loaded to provide a crushing force by a strong adjustable spring 37, and a column portion 10 2 , 28 through which fluid from a duct 22 passes into the bottle to exert an internal pressure, the bottle being accepted if holes 26, 27 and 39 become aligned to allow a beam of light A-B to pass through. The device comprises a vertical column 10 slidable in a fixed frame 11, the parts 10 1  102 of the column being connected by flanges 13, 14 clamping an elastic pressure sensitive diaphragm 15 defining a lower space 17 communicating with the bottle interior through a pipe 21, and an upper space 16 pressurized by fluid blown in through a hole 18 and regulated by means of an escape nozzle 19. The bottle interior also communicates through a pipe 21 with the space 17. The offsetting between the passages 26, 27 and the size of nozzle 19 are so designed that when the device is applied to a sound bottle and the spaces 16, 17 are pressurized from a single source the passages 26, 27 become aligned. A sliding sleeve 38 is provided with light holes 39 at a distance d which is slightly less than l 1 +l 2  so that when holes 27 and 39 are aligned the rings 33, 34 are not in contact and 29 is pressed against 30 only by the spring 32. In operation a pressure is permanently applied through 18 so that the diaphragm rests upon 25. The column 10 is then lowered to bring its passage 27 below A-B and the holes 39 which remain stationary. The gasket 29 then contacts the mouth 30 and as a result of the stiffness of spring 37 the spring 32 is compressed until rings 33, 34 contact. Further lowering of the column 10 then compresses 37 and a hook 40 integral with 42 nearby abuts the upper part of sleeve 38. In a second phase the column 10 is raised sufficiently for its passage 27 to become situated in the line of sight A-B and the rings 33, 34 move apart so that the gasket 29 is pressed on to the mouth 30 only by the spring 32. A pressure of a few millibars is then applied through duct 22 and if the bottle under test is sound this pressure is transmitted to the space 17. Now as the pressure in the space 16 is slightly lower due to the escape through nozzle 19 then 26, 27 and 39 become coaxial. Automatic rejection of faulty bottles can be arranged and if the bottle is not perforated but not resistant to crushing then the hook 40 will move the sleeve 38 and the holes 39.

Title: Coloration process
Inventor: JAMIN GUILLAUME WARD
IPC: D06P3/36
Filed: 1964-10-29
Abstract: A process for colouring synthetic textile materials comprises padding or printing the material with an aqueous dispersion in a single phase system of one or more disperse dyestuffs and subsequently steaming the material with superheated steam at substantially atmospheric pressure.  Superheated steam is steam obtained by heating ordinary steam in the absence of water, thus giving the steam a higher temperature than the temperature of saturated steam at the same pressure.  The temperature of the steam is at least 120 DEG C. Textile materials used include cellulose acetates, synthetic polyamides and polyesters and unions of these materials with cotton and wool.  Reactive disperse dyes are used and the aqueous dispersion may contain conventional additives, e.g. urea and condensates of ethylene oxide with an alcohol, an amine or a phenol.  A suitable steamer is the one described in Specification 1,088,643.

Filed: 1945-11-09
Abstract: 601,358. Telemotor systems. ADEL PRECISION PRODUCTS CORPORATION. Nov. 9, 1945, No. 29993. Convention clate, May 25. [Class 69 (ii)] In a closed hydraulic system in which a master unit A and a slave unit B are connected with pipes for the operation of one by the other, a supply control valve F interposed in one of the pipes between the master unit and the slave unit is connected with a source of supply m of operating liquid, the valve F containing a seating member 6 and a valve element 10 for permitting flow of liquid from the source into the system, the seating member being adapted to be moved manually in engagement with the valve element to prevent flow from the source without interfering with the circulation of operating liquid in the system. The system includes a pressure equalizer D, and the slave unit is provided with an hydraulic valve locking means comprising a floating piston 45 for actuating spring-loaded poppet valves 46, 48, Fig. 7. When the piston P of the master unit is moved to the left liquid is drawn from the source m past the valve element 10 into the pipe C. Movement of the piston to the right then forces the liquid past valve 4 into the pipe c', so that the master unit can be used as a pump to fill the system, air being removed through the bleeder fitting K. When the member 6 is screwed down to permanently seat the element 10, flow from the source is prevented but the element 10 then engages a pin 5 which holds the valve 4 open to allow the liquid in the system to operate freely. The pressure equalizer D, Fig. 4, comprises a hollow spring-loaded differential piston 9 forming cylinder spaces 16, 17, of equal crosssectional area, the space 16 being connected to pipes C<SP>1</SP> and E, and the space 17 to pipes G and H. The central bore of the movable piston 9 houses a hollow fixed piston 23. The space 25 below, and the space above this piston are filled with liquid up to the dotted line 26, flow from the upper space to the lower being through a spring-loaded valve 29 and in the reverse direction through a spring-loaded valve 34. Movement of the piston 9 is controlled by the flow of liquid through the piston 23, this flow being governed by the strength of the springs seating the valves 29 and 34.

[Class 7 (v).] An engine starter comprises two simultaneously actuated racks b engaging at opposite sides of a pinion c, the racks and the pinion having inclined teeth whereby the pinion is moved axially into engagement with an engine shaft a to be driven on longitudinal movement of the racks. The latter may be actuated pneumatically, hydraulically, or by explosion gases, or by an electric motor, an inertia starter comprising a flywheel, an electromagnet moving armatures coupled to the racks, or resilient means such as springs. As shown, the racks b are formed on tubular members g carried by pistons h moving in compressed-air cylinders e and returned by springs i. Axial movement of the pinion brings clutch teeth d<1>, Fig. 3, into engagement with teeth d<2> on the engine shaft a. Accidental engagement of the clutch teeth d2 during normal running is prevented by spring-actuated balls l carried by the pinion and engaging helical grooves k, Fig. 4, in a fixed bearing shaft j, the grooves being opposite in pitch to the teeth of the pinion. In a modification, the shaft moves with the pinion. Starting may also be effected manually by means of a handle on a sleeve m, Fig. 3, arranged within the shaft and having clutch teeth n.
