IPC: B66D1/22
Filed: 1919-08-07
Abstract: 130,999. Bernard, P. B., and Moutier, A. L., (Assignees of Miot, H. F. H. G.). Sept. 22, 1913, [Convention date]. Constant-tension and tensionregulating winding and paying- out apparatus; brakes and retarding-apparatus; driving-gear.-The hoisting-drum 29 is driven from a pulley 33 through reducing-gearing 3, 6, 5, 2, the toothed wheels 6, 5 being fixed together and ro. tating on a pin in a brake-drum 1. The brake-drum is normally prevented from rotating by a spring- actuated brake-band, but when the load is excessive the brake slips and the drum 1 rotates backwards. The load is sustained by ordinary selfsustaining-gear comprising a ratchet wheel 27, pawl 28, and brake drum 26. The speed of hoisting and lowering is governed by manipulating the brake on the drum 1.

Title: Improvements in volumetric liquid meters
IPC: G01F3/18
Filed: 1939-07-05
Abstract: 534,771. Liquid meters. BOUTILLON, H. July 5, 1939, Nos. 19592 and 19593. Convention dates, July 5, 1938 and Feb. 13, 1939. [Class 69 (ii)] A volumetric liquid meter is constructed of a number of similar units which can be joined up in parallel to deal with high outputs, or which can be used singly for low outputs. Each section comprises an inlet fitted with a gas separator, and the liquid passes from this to a chamber 22 in which is arranged a valve 24, Figs. 3 and 4, or 47, Fig. 7, which controls the flow of the fluid to two pair of cylinders 2, each pair being fitted with pistons, 3, 4, connected by rods 5, 6, and fitted with rollers 14 adapted to impart rotary motion to a shaft 16 by acting on a pair of cams 15, disposed at right angles one to the other and shaped so that reciprocation of the pistons rotates the shaft 16 uniformly. The rods 5, 6 are guided in sleeves 7, 8, 9, 10 fitted with anti-friction bearings. The shafts 16 of adjacent units are connected together by means of polygonal ends 17 and a similarly shaped spring-pressed sleeve 44. The faces of the polygon are preferably in the form of part of a cylinder, so that a Universal joint results. The valves 24 are carried by cranks 32 on shafts 28 driven by bevel gearing 29, 30 from the shafts-16, and planetary gears 37, 36: 34, 33 give the valves circular movements about the shaft 28 without rotating on their own centres. Each valve co-operates with four apertures 23 arranged in a square, and as shown in Fig. 3, the valve 24 is in such position that the right aperture 23 is open to permit the fluid to pass to one pair of cylinders and the left aperture 23 permits the measured fluid to pass to the outlet. A shaft 40 driven by the planetary gears operates an indicator. In a modified form of valve 47, Fig. 7, the valve is rotated intermittently through 90 degrees by a roller 53 on a sleeve keyed to the shaft 28, and this roller engages a triangular notch 56 in a concentric sleeve on the valve 47. The centre of fluid pressure P on the valve is vertically above the roller 53, so that when the roller is rotated it produces a vertical pressure component tending to minimize the fluid pressure. As shown one pair of apertures 23 is controlled by the valve so that the liquid can enter by a slot 50 in the valve and leave by the port 51. The other pair of apertures 23 are closed by solid members on the valves. The casings of the individual units can be connected by bolts 43, and the main parts of each section are assembled on a frame 42 before this is connected to the adjacent section.

Title: Improvements in or relating to mouth plugs for ammunition cartridges
IPC: F42B5/38
Filed: 1936-07-15
Abstract: 478,257. Ammunition cartridges. ARMSTRONG, J. J. V. (General Hydraulic Co.) July 15, 1936, No. 19598. [Class 9 (i)] The mouth plug 2 of an ordnance cartridge consists of a relatively rigid outer portion 10 consisting, for instance of finely ground cork of relatively high tensile strength, and an inner portion 11 of relatively soft and frangible material, such as coarsely ground cork. The outer portion is sufficiently hard to withstand impacts during the loading operation, while the presence of the frangible portion ensures that the plug will break up into small fragments upon firing. In the construction shown, the portion 10 is in the form of an annular ring which is formed with a reduced portion which fits into the end 9 of the cartridge case 6 to which it is cemented. The inner portion or ,core 11 is cemented or glued to the portion 10. The exposed surface of the plug may be impregnated with graphite or like material, to reduce friction between the plug and projectile 5 and between the plug and bore of the gun. In a modification, the outer portion of relatively rigid material is moulded to form the complete nose of the plug.

Title: Improvements in or relating to means for feeding articles to wrapping machines or the like
IPC: B65B57/14
Filed: 1926-08-10
Abstract: 278,836. Rose, W., and Rose Bros. (Gainsborough), Ltd. Aug. 10, 1926 Stopping driving pulley on stoppagc of the conveyer or elevator.-Relates to means for feeding articles to wrapping machines &c., wherein the articles, in block form, are conveyed along a channel by a chain conveyer to a. position where a plunger thrusts each article into a pocket in the wrapping machine or on to a platform. According to the invention, means are provided for throwing the feed out of action when an abnormally large article arrives on the chain conveyer. As shown, the articles 10, Fig. 1, are conveyed towards the left by pushers 9 on a chain 1 through a channel 5, 6 and beneath a finger 15 which holds each article until it is thrust into the wrapping machine,&c. by a lateral plunger. The chain 1 is driven from a shaft 4 by a sprocket 2 freely rotatable thereon and having an integral flange 29 from which project pins 28. During normal operation one of the pins is engaged by a catch-lever 24 pivoted at 26 to lugs 25 on a driving element 22 on the shaft 4. The catch-lever is held in engagement with the pin 28 by a spring 33, but, if any resistance to the travel of the chain 1 is offered, the spring 33 yields and allows the shaft 4 to rotate without rotating the sprocket 2. A gauge bar 21, Fig. 3, is arranged above the sides 5, 6 of the channel so that if an article of abnormal size is being conveyed, it impinges against the gauge member and stops the travel of the chain until removed. The side portions 13, 14 of the base plates 8 of the pushers 9 project into grooves 11, 12 in the sides 5, 6 of the channel, to ensure the correct position of the pushers.

Abstract: 693,374. Pistons; engine cylinders. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Aug. 3, 1951 [Aug. 8, 1950], No. 19677/50. Class 122(i) [Also in Groups XXIX and XXXI] In a system of transmitting power from a prime mover to a road wheel by hydraulic or like pressure means without mechanical connection and of the kind in which rotation of the wheel is obtained by means of engines of the type comprising a piston reciprocating in a cylinder, disposed radially within the wheel, and acting collectively as a rotary engine, the system includes a device for changing the speed range, the device consisting of one or more sleeves provided around the piston within the cylinder, which sleeves are adapted to be locked in position by means of catches operated under hydraulic control, whereby the effective diameter of the cylinder may be varied according to the required range of speed. In the arrangement shown, a plurality of cylinders a is pivotally attached to a wheel disc c which is carried on bearings e on a stationary axle f. Pistons g are connected to an eccentric h integral with or secured to the axle by means of pads i bearing on a ring j mounted on bearings k on the eccentric. Oil is admitted under pressure to the cylinders on one side of the eccentric and exhausted therefrom on the other side of the eccentric, through a valve l connected by pipes m<SP>1</SP>, m<SP>2</SP> within the axle f. Direction of rotation of the wheel is dependent upon direction of flow of oil through the pipes m<SP>1</SP>, m<SP>2</SP>. Two speed ranges are obtained by means of a sleeve o which surrounds each piston and which for one speed range is prevented from moving downwards by a catch p, see Fig. 3. The catch p is operated by oil pressure from a pipe connected to the centre of the axle. When oil is admitted to the pipe a spring-loaded fork r moves the catch p to the position shown as each successive cylinder passes through top dead centre. When the oil pressure is released, the catch is withdrawn as each cylinder passes top dead centre. The catch is retained in either position by a spring loaded pin t. An additional fork may be provided to obtain more than two speed ranges. Over-running is prevented by means of piston-controlled flap valves arranged in oil passages to the main cylinders within the valve l. According to the Provisional Specification, the reaction element may be mounted separately from the wheel and a reduction gear inserted between them.

Title: Improvements relating to the production of fermentable sugars
Filed: 1929-06-26
Abstract: 315,403. Soc. des Brevets Etrangers Lefranc et Cie, (Assignees of Soc. Anon. le Vetol). July 13, 1928, [Convention date]. Glucose &c.-Fermentable sugars are prepared by the hydrolysis in two stages of materials containing cellulose or similar substances at pressures which are the same in both stages or which increase from the first to the second stage. Cellulose or substances which contain it in the impure state, residual cellulose from sugar manufacture, carobs, or amylaceous substances containing starch in predominant quantity or associated with cellulose materials, are charged into a pressure resisting apparatus provided with an agitator, along with a solution of sulphuric acid in water. After the temperature of the agitated mass has been raised, dry live steam is injected into the apparatus until the desired pressure has been obtained: this pressure being maintained for a predetermined time. The sugar solution obtained is discharged in a rapid manner, e.g. through an opening provided with a. screen, and a further solution of sulphuric acid in water is added to the residue. As before, steam is injected, the mass allowed to remain under pressure for a predetermined time, and the further yield rapidly discharged. If sugar is present in the primary material, it may be allowed to remain or may be first extracted by any usual process. The Specification as open to inspection under Sect. 91 (3) (a) states that the hydrolyzing substance may be hydrofluoric, hydrochloric, hydrobromic, hydriodic, nitric, phosphoric, &c. acids, bisulphates, acid phosphates, &c., that the solutions of fermentable materials obtained are purified by calcic or other suitable treatment to eliminate and recover if desired, pectic substances, tannins, gums, &c., and, that after purification, the mixture is rendered acid, neutral, or basic, according to the fermentation desired : alcoholic, acetonic, butyric, &c. This subject-matter does not appear in the Specification as accepted.
