Title: Improvements in or relating to pasteurising or sterilising apparatus
IPC: A23L3/00
Filed: 1936-05-22
Abstract: 475,739. Pasteurizing or sterilizing apparatus for bottled &c. goods. GREENSLADE, W. R. May 22, 1936, No. 14518. Addition to 431,939. [Class 49] [Also in Group XXX] In a pasteurizing or sterilizing apparatus as described in the parent Specification, the movable gate member or members 10, which control the number of bottles B to be transferred at one time to the main conveyer by the pusher, are operated by fluidpressure means automatically controlled by timing-means operated from the main drive shaft 22. As shown, the timing-means comprises a cam disc 59, the periphery of which is trailed by a cam follower 58 on a lever 55, pivoted at 57, and connected to a piston-valve rod 47 which is urged by a compression spring always to keep the follower 58 in contact with the cam. The fluid pressure, e.g. air pressure, is supplied by a pipe line 30, union 35 and ports 38 to the space between the piston parts 46, 46a of the valve, the ports 37, 39 being opened in alternation to supply pressure, through pipe lines 27, 28, in alternation to the top and bottom of the piston 18. Exhaust passages 49, 50 are provided in the glands' 48a, 48 of the valve body. A similar valve is arranged alongside the valve described above, and the two valve bodies are secured together by sheaths 32 and are attached to the panel 31 by brackets 32a. The latter valve is operated by rollers 60 on the side of the disc 59 engaging a cam follower 58a on a lever 55a, also pivoted at 57, and actuating the piston valve, the body of which has an air supply 41 and outlets 40, 42. This valve controls a double acting piston operating the feed-in pusher. The gates 10 are slidable in guides 11 and are actuated by bell-cranks 26 connected to slide rods 24 secured to a cross-head 23 on the piston rod 20. The cam followers 58, 58a are adjustably mounted on the ends of the levers 55, 55a. In a modification, the sliding piston valves are replaced by oscillating threewav cocks, the return movements of which are effected by weighted levers. Single acting pistons may be used for operating the gates 10 or the feed-in pusher, the return movements being effected by springs or weights. Oil, steam or water may be used as the pressure fluid medium.

Title: Improvements relating to the governing of water turbines
IPC: G05D13/00
Filed: 1921-05-28
Abstract: 183,310. Dunne, J. J. May 28, 1921. Regulating.-The inlet-valve opening of a. water turbine is governor-controlled. Pawls 12 - - 15 are mounted on a frame 10, 11, oscillated continuously on a shaft 5 from an eccentric 16 on the main shaft 18, and they rest normally on a shield 24, 25, fastened to a wheel 22, which can be rotated on the shaft 5 by the movement of a governor sleeve 34 through a link-and-lever system 26 - - 31. Right and left hand ratchet-wheels 1 - - 4 are fixed on the shaft 5 on either side of the wheel 22, underneath the shield 24, 25. Increase in speed lifts the governor sleeves 34, and turns the wheel 22 in the direction x; this removes the shield 24 from under the right-hand pawls, which engage the ratchet-wheels 1, 2 and rotate the shaft 5, and with it the valve-rod 9 to clcse the valve. Decrease in speed from the normal gives opposite rotation of the valve-rod 9 through the wheel 3, 4. Reference has been directed by the Comptroller to Specifications 5274/79, 6855/07, and 10593/08.

Title: Improvements in or relating to valve devices for maintaining a constant pressure inside a closed space more particularly in the cabin of an aircraft
IPC: B64D13/04
Filed: 1947-06-05
Abstract: 646,287. Regulating cabin pressure. SOC. NATIONALE DE CONSTRUCTIONS AERONAUTIQUES DU SUD-OUEST. June 5, 1947, Nos. 14925 and 14926. Convention dates, Oct. 26, 1943, and Feb. 16, 1944. [Class 4] [Also in Group XXIX] The pressure in an aircraft cabin 1, Fig. 2, supplied with air by a supercharger, is maintained constant by means of an outlet valve, shown as a balanced double-beat valve 19, which is actuated by a piston 10 closing one end of an auxiliary control chamber 12, the latter being provided with a leak port, and the pressure of the air therein being controlled by a pilot valve loaded by a bellows containing air under a predetermined pressure. Air from the cabin leaks into chamber 12 through a bleed 13 or past the piston. 10, and a constant pressure is maintained in the auxiliary chamber by means of a relief valve 14, the latter being spring- loaded and carried by a bellows containing air under pressure. Valve 19 is also loaded by a light spring 21. The cylinder in which piston 10 operates may be separate from, but in communication with, chamber 12, and a cock may be provided to allow compressed air to flow into the system to close valve 19 positively. The latter may be constituted by a sleeve sliding over a tubular seat provided with a triangular port or a straight or helical row of ports. In a modification, the outlet valve 16, Fig. 10, is actuated by a leaky piston 10 controlled by an auxiliary chamber 12 with relief valve 14. The top of tubular valve 16 is, however, covered in and provided with a valve 30 which, during normal operation, is opened by the pressure in the cabin 1. Should the pressure in the cabin fall too low, valve 30 will close, the air then entrapped in the chamber 31 will leak away to outside atmosphere through the space between valve 16 and its seat, and the pressure in chamber 12, combined with the weight of the valve &c., will close valve 16 against a packing strip 28. In a further modification, the control chamber constituted by chamber 12, Fig. 11, conduit 32, and space 12a, is normally at the pressure of the outside air due to the leakage past piston 35 and out through openings 38, and, under these conditions, the weight of the piston and the outlet valve 33 will lower the latter on to its seat. As soon as the pressure in cabin 1 rises sufficiently to overcome the force due to spring 5 and the pressure of air in capsule 6, valve 3 will open and air at cabin pressure will flow into space 12a to lift the latter and open valve 33.

Abstract: 678,872. Delivering measured quantities of granular materials. GASKELL & CHAMBERS, Ltd., (trading as NON-DRIP MEASURE CO.). May 21, 1951 [June 15, 1950], No. 14984/50. Class 106(v) Apparatus for delivering measured quantities of powdered or granular materials, such as sugar, tea and milkfood products, comprises a spindle 5 supported and guided at both ends in a horizontal cylinder 1 and a measuring chamber 12 formed by two piston members 8, 8a, axially spaced on the spindle, the spindle being axially movable by hand from a position in which it registers with a supply port 13 to a position in which it registers with an outlet 16. One piston member 8a is adjustable on the spindles to vary the volume of the measuring chamber by means such as a screw-thread connection and a lock nut 9. To facilitate the flow of material, the part of the spindle in the chamber may be of reduced cross-section and the return spring 11 may be fairly strong so as to jar the apparatus; the latter action may be assisted by mounting the apparatus resiliently. For use with tea or other fibrous material, the piston faces may be sharp-edged so that they shear any trapped material, and for use with powder, where, owing to the spindle being supported at both ends, the pistons may be a fairly loose fit, a hole 18 is provided through which any material passing the piston 8a is blown out by the action of the pistons. The spindle is either provided with a hand knob 10 or is operated by a pivoted lever connected to it by a crank.

Filed: 1928-05-22
Abstract: 320,847. Colas Products, Ltd., and Gabriel, L. G. May 22, 1928. Drawings to Specification. Emulsions, making.-Bituminous emulsions, for use directly in making and repairing roads and in coating road-making materials, are prepared in unstable form, the particles having at size of 10 Á or greater, and are subsequently stabilized by the addition of an agent such as a protein or starch or other carbohydrate. The final emulsion is stated to combine the properties of bulk stability with ready precipitation in contact with a road or like surface or with mineral aggregate. The unstable emulsion is prepared by the use of quantities of soap less than those required for the production of a stable emulsion by the same apparatus. Colloid mills or stirring apparatus may be employed. Examples in the Specification describes (1) the production of unstable emulsions of Venezuelan asphalt in a colloid mill employing potassium soap containing 0.4 per cent and 0.2 per cent of olein respectively reckoned on the bitumen, the emulsions being subsequently run into 0.5 per cent gelatinesolution; (2) the production of a bituminous emulsion in a slow moving agitator employing a soap containing 2 per cent of olein reckoned on the bitumen, the emulsion being stabilized as in (1). Specifications 238,967 and 286,552 are referred to.

Title: Improvements in or relating to methods of manufacturing bulged gauze articles
IPC: H01J37/295
Filed: 1966-04-05
Abstract: 1,086,403. Making screens and electrodes. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. April 5, 1966 [April 8, 1965], No. 15107/66. Heading B3A. [Also in Division H1] A method of making a part spherical &c. article from gauze made of wire of less than 50 microns diameter comprises the steps of coating a piece of flat gauze with a soft metal to a thickness of less than 10 microns, deforming the gauze to a part spherical &c. shape causing the wires to slip relative to each other, and heating in a neutral or reducing atmosphere to cause the layers of soft metal to become joined by diffusion. When the gauze is coated in the flat state the layers of soft metal 3, 4 do not penetrate between the wires 1, 2, Fig. 1 (not shown), and when the gauze is deformed by clamping the outer edges and pushing over a jig, Fig. 5 (not shown), the coating breaks and the wires slip so that at the crossing points of the wires there is a layer of coating material between them, Fig. 2 (not shown). Heating the article causes the coating to become joined by diffusion without the wires becoming completely embedded in the coating so that the resulting construction is springy and not liable to denting. The gauze may be made of tungsten or molybdenum wire and the soft coating may be gold, silver, copper or aluminium and may be applied by electrodeposition or by vapour deposition. The article produced may be used as an electrode for a diffraction tube, a sieve or as a mask for the application of metal from the vapour phase. Additional parts such as rings (9), (10), (11) (Fig. 5) may be joined to the gauze by the heating process.

Abstract: 632,969. Feeding sheets. ROSE, A. G., GILBERT, J. A., and ROSE BROS. (GAINSBOROUGH), Ltd. June 14, 1947, No. 15740. [Class 100 (i)] In a sheet-feeding mechanism the sheets are separated from the bottom of a pile 12 by means of oscillating suckers 17 which are carried by a stirrup 18 pivoted at 19 to a pair of supports 21 arranged at each side of the magazine 13 and carried by a parallel linkage 24 operated by a cam 31 on a cam-shaft 32 to move the supports 21 towards and away from the pile 12. The suckers 17 are also operable by a cam 33, Fig. 2 (not shown), which moves the stirrup 18 from the position shown in Fig. 1 to the position shown in Fig. 4, in which the suckers engage the lowermost sheet in a position between a pivoted support 16 and a support 53 which is moved away from the pile as the suckers withdraw the lowermost sheet. To prevent double feed the separated sheet is pierced by one or more needles 37 carried by spring-depressed supports 36 arranged in the suckers, and which are raised by oscillating tappet members 41 so as to pierce the sheet attached to the suckers and move towards the pile any sheet adhering to the separated sheet. The sheets are finally fed by reciprocating grippers, or by feed rollers 46, 47 which are of sectional form so as to permit the suckers to be withdrawn below the periphery of roller 46 when the roller 47 is moved by oscillating levers 48 to engage the roller 46. The support 16 moves down at the same time that the rollers 46 do.
