Filed: 1947-02-24
Abstract: 621,424. Endless belt conveyers. SHEPPARD, W. V. Feb. 24, 1947, Nos. 5364 and 13678. [Class 78 (i)] In an endless belt conveyer, sections of the belt 15, Fig. 1, at intervals in the operative conveying length thereof are given a steeply inclined trough section by operating upon a movable endless length of underbelt 14 which is of greater width but confined to an operative length substantially equivalent to that of the desired steeply inclined trough section, said under belt being interposed between the belt 15 and supporting troughing rollers 13 therefor, which rollers are set at angles of inclination to impart the trough formation to the belt 15 whereby when the material being conveyed enters the steeply inclined trough sections, it is caused to collect in a substantially centralised heap on the belt 15 for continued conveyance in that condition after passing out of said trough section. The troughing rollers 13, which are arranged at a greater inclination to the horizontal in the centre of each troughing section than at the ends, may be eccentrically mounted and resiliently covered to assist the movement of material from belt 14 to belt 15, and opposite pairs of end rollers may be spring-loaded to allow the passage of especially large pieces of material. End tensioning rollers 16 may have either concave or convex surfaces to impart the curved formation to the under belt Where a troughed section is situated adjacent a telescopic pan 20 at the return end of the conveyer the spillage into said pan is returned to the belt 15, Fig. 3, by the belt 14 on to which the spillage is delivered by ploughs 21 situated near the funnelled end of a supplementary pan 19. The belt 14 which is normally driven by frictional contact with the belt 15 may also be driven by a separate motor (not shown).

Title: Compositions of water-soluble cellulose derivatives
IPC: C08B11/00
Filed: 1959-02-16
Abstract: Cellulose derivative compositions comprise 5-95%, preferably 20-80%, by weight of a watersoluble ethyl-hydroxyethylcellulose and 95-5%, preferably 80-20%, by weight of at least one water-soluble ionic cellulose derivative which is (1) a cellulose alkyl ether of which the alkyl radical contains a carboxylic or sulphonic acid group, or (2) cellulose in which the anhydroglucose unit contains one or more acid sulphate groups, or (3) a water-soluble salt of one of these acid cellulose derivatives.  The ionic cellulose derivatives may be the water-soluble salts of carboxymethyl-or carboxyethyl-cellulose, of sulphomethyl- or sulphoethyl cellulose, or of cellulose sulphate. In an example, an ethyl-hydroxyethylcellulose having a viscosity of 7715 cp. (2% aqueous solution at 20 DEG C.) and containing 18% of ethoxyl and 16% of ethylene oxide is mixed in equal proportions by weight with a sodium carboxymethylcellulose having a viscosity of 5940 cp. (2% aqueous solution at 20 DEG C.) and a degree of substitution 0,47.  The viscosity at 20 DEG C. of a 2% aqueous solution of the mixture is 14530 cp., i.e. much higher than that of the ethyl-hydroxyethyl cellulose.  The invention enables aqueous cellulose derivative solutions of high viscosities to be obtained at a low concentration of the derivatives.

Title: Improvements in or relating to servo-assisted clutch-operating mechanisms
Inventor: FARMERY GEORGE KENNETH
IPC: F16D48/04
Filed: 1959-02-19
Abstract: 875,514. Clutch control. CLAYTON DE-WANDRE CO. Ltd. Feb. 8, 1960 [Feb. 19, 1959], No. 5798/59. Class 80 (2). In a fluid pressure servomotor clutch control system for effecting rapid disengagement and controlled re-engagement of the clutch, the second stage of the re-engagement is effected more slowly by the closure of a restrictor valve when the pressure in the servo-cylinder falls to a predetermined value. In the arrangement shown, operation of a micro-switch 23 on the gear lever opens a solenoid-controlled valve 27 to admit compressed air from a supply pipe 28, through a pipe 11, past a non-return valve 12, into the cylinder 1 to act upon the piston 2 and disengage the clutch 5 through a lever 4. The pressure of the air acting upon a diaphragm 18 lifts a restrictor valve 17 off its seating 16 against a loading spring 19. When valve 27 is closed, air from cylinder 1 escapes directly through a by-pass 15 opened by valve 17 until the pressure falls to a value when spring 19 re-closes valve 17, when it can only escape through the restriction 22 in the valve, thus reducing the rate of clutch re-engagement.

Title: Improvements in or relating to friction clutches and brakes
IPC: F16D67/04
Filed: 1938-02-24
Abstract: 489,606. Friction clutches combined with brakes. SCHULER AKT.-GES., L. Feb. 24, 1938, No. 5907. Convention date, Feb. 24, 1937. [Class 80 (ii)] The clutch of a combined friction clutch and brake in which the plates rotating with the driven shaft upon which the clutch and brake engaging forces act directly are connected together rigidly is engaged by air pressure and disengaged by spring action, the force of the spring being only sufficient to disengage the clutch, whereas the brake is engaged by continuously acting air of lower pressure than the air for operating the clutch. In one arrangement, an annular chamber 19 or a number of cylinders 18 are located between the clutch 6 and the brake 4 and rotate with the shaft. Working in the annular chamber or each cylinder is a spring pressed piston 21 or 20 secured to a rod 24 or 22 which rigidly connects the presser plates 14 and 10 of the clutch and brake respectively. Pressure air for engaging the clutch is admitted to the spaces 26 in the chamber or cylinders through a conduit 29, an air vessel 31, a three-way valve 32 and bores 33, 34 when the three-way valve is set in the appropriate position. Air of reduced pressure is supplied to the spaces 27 of the chamber or cylinders from the air vessel 31 through a reducing valve 35, an equalizing vessel 36 and bores 38, 39. This reduced pressure air acts continuously so that when the three-way valve releases the air in the spaces 26 the springs 28 disengage the clutch and the air in spaces 27 operates the brake. In a modification an externally located pressure air cylinder operates the clutch and brake by means of a piston rod passing axially through the shaft and connected by a linkage held in a hub of the shaft to the rod of the clutch and brake presser plates. The externally located cylinder is controlled by a three-way valve in a similar manner to the cylinders of the first described arrangement.

The projections 4 are of greater vertical height than the bearing 7 and are rigidified by compression when the nut 12 bears on the upper plate 8 so that sideways tilting of the seat is prevented, and buffers 5, 6 form resilient stops limiting fore and aft tilting on the projections 4 as centres. The projection 5 at the rear of the seat is of less vertical height than the projection 6 which is at the front of the seat so that the seat is tiltable further in the rearward direction than forwardly. The bolt is welded to the lower plate 9 and the nut 12 bears on the plate 8 through a resilient washer 11. In modifications, the projections are formed by pins bonded into the pad or are of equal or less height than the bearing portion and are compressed by localized depressions in the plate 8, or the resilient pad is square, the bearing portion being formed as a raised rectangular portion round the central aperture.

Title: Improvements in apparatus for making aerated beverages
IPC: B67C3/06
Filed: 1932-02-29
Abstract: 379,633. Aerating-apparatus ; bottling; pumps. MARCHOU, E. R., 55, Avenue Ste. Foy, Neuilly-sur-Seine, Paris. Feb. 29, 1932, No. 6047. Convention date, March 2, 1931. [Class 14 (i).] Apparatus for the rapid making of aerated beverages such as lemonade, comprises a water pump 2, a gas-inlet pipe 6, a tank 8 containing an aerating device connected with the pump by pipes 9, 9a, 5, a constant-level reservoir 28 fed from the tank, an essence-measuring device, and a bottle filler. The aerator comprises a perforated ring 14 from which the mixture of gas and liquid passing up through the pipes 9, 9a issues in intersecting jets into a pipe 16 connected to a strainer 18 and thence into the tank. The pressure in the tank forces the aerated liquid up through a " siphon " pipe into the reservoir 28, which contains a, float valve controlling the inlet. A pipe 35 leads from the upper part, and a pipe 34 from the lower part, of the reservoir to convey gas and aerated water, respectively, to the filler 37, in which is a spring-pressed double piston valve. When a bottle is placed on a stand 48a and pressed against the nozzle 42, the piston is'raised and gas passes down into the bottle, and then, when the orifice 41 is uncovered, liquid. The upward movement of the piston also admits gas to the underside of a spring- pressed piston in a cylinder 52. The rod 55 of this piston is connected by levers 59 with the rods of pistons in cylinders 57 which are supplied with syrups from vessels 62. When the rod 55 rises, therefore, the contents of the cylinders 57 are expelled and enter the bottle by way of a pipe 51 passing down through the piston valve. The amount of syrups discharged is regulated by means of a hand-lever 79 connected to a cam which acts as a stop on one of the levers 59. The syrup containing the citric &c. acids is kept in one of the vessels 62 and the syrup containing flavouring in the other. The gas used in raising the piston escapes at the end of the stroke by apertures in the cylinder walls into passages 77, Fig. 11, and recesses 75 in the bottoms of the cylinders 57. It is prevented from entering these cylinders by ball valves 73 but passes by orifices 71 into pipes leading to the pipe 51, Fig. 2, whence it drives the syrup therein into the bottle. When the bottle is removed the springs restore the piston 53 and piston valve to their original positions.
