Title: Improvements in or relating to air pressure operated control systems
IPC: B60T15/50
Filed: 1947-01-06
Abstract: 638,706. Fluid-pressure-operated brakes. CLAYTON DEWANDRE CO., Ltd., EDGE, S. H., and WILLETT, S. E. Jan. 6, 1947, No. 425. [Class 103 (i)] [Also in Group XXVIII] Compressed air systems for operating brakes or other devices, include a reservoir arranged to be charged by a compressor through a non- return valve, an unloader valve for diverting the supply from the compressor to the atmosphere when a predetermined pressure has been reached in the reservoir and a valve which determines the maximum pressure of air supplied to the brake &c. operating cylinder by a main control valve, from the reservoir or from a subsidiary reservoir supplied from the first reservoir, this maximum pressure being less than that determined by the unloader valve. Fig. 1 shows a small reservoir 1 adapted to be connected through passages 7, 5 with the driver's valve of the brake system of a motor vehicle. When charging the system, the several valves being initially in the positions shown, air from the compressor connected to port 4, flows through passages 9, 14, 7 past non-return valve 11, and reducing valve 15, to the reservoir 1. When the pressure acting in space 13 on a bellows 16 is sufficient to overcome spring 30, the valve 27 is opened to permit a main reservoir 2 also to be supplied. When both reservoirs have been charged to a pressure which acting on the bellows 18 of the reducing valve 15 overcomes the spring 19, this valve is closed to cut off the reservoir 1 from the compressor which continues to charge the reservoir 2 until the pressure therein acting in bellows 36 unseats the unloader valve 39 against the pressure of spring 38, thus diverting the supply to atmosphere through port 6. When upon operation of the driver's valve to apply the brakes, the pressure in reservoir 1 falls, the reducing valve 15 opens to supply this reservoir from the reservoir 2 through a non-return valve 23 as the valve 27 closes and if the pressure in reservoir 2 falls sufficiently, the unloader valve 39 closes. The small reservoir and valve 27 may be dispensed with and the reducing valve 15 may be disposed adjacent the driver's valve, either at the reservoir or the brake cylinder side thereof.

Title: Improvements in prepayment mechanisms for meters
IPC: G07F15/02
Filed: 1921-01-06
Abstract: 179,580. Fox, T., and Robinson, S. Jan. 6, 1921. Delivery by meter; coin action, mechanical connection and multiplecoin. - Relates to meters of the kind in which a coin is used to connect a lever and the quantity wheel, and to apparatus which may be set to operate with either of two coins of different value as required. The lever can be fulcrumed in either of two positions, and means are provided for varying the gearing accordingly between the meter-mechanism and the valve-operating member. An angle lever 13 is pivoted on a pin 15, which can be mounted in either of two bearings 21, 22 in a hand-operated spindle 8. When the lever is in the position shown, a small coin, say a shilling, inserted in a rotary carrier 11 forces the end 17 of the lever into engagement with the quantity-wheel 4. A larger coin, for example a penny, is effective when the pivot pin 15 has been shifted to the bearings 22. The valve lever 29 is engaged by a collar on a slotted sleeve 25, which is threaded on to a screw 24 connected to the quantity-wheel. A wheel 34 having a screw 32 engaging in the slot in the` sleeve 25 is so mounted that it can be made to gear either with a worm 39 directly connected to a meter-driven spindle (not shown) or with a worm 36 geared to the worm 39 through a pinion 38. The wheel 34 is placed in the latter position when the lever 13 has been set for operation by a shilling, and in the other position when a penny is to be used. A forked hand-lever 44 may be provided for shifting the wheel 34. In the modification shown in Fig. 4, the change in gearing is effected by reversing the wheel on the sleeve 25, either the face of the wheel or a collar 33 thereon, as the case may be, abutting against a stop 52. A pivoted catch 53 prevents sliding of the wheel during operation. Indicators.-The amount of gas prepaid is shown by a drum 31 on the valve spindle 30, the drum having two separate scales on opposite sides of the periphery and being adjustable so that either scale passes behind an index on a window 46.

Title: Manufacture of leavened bread
IPC: A21D8/04
Filed: 1921-01-06
Abstract: In the manufacture of leavened bread, the dough batch has mixed with it before fermentation, diastatic and proteolytic enzymes produced by the action of any enzyme-producing fungus such as a fungus of the genus Aspergillus upon carbohydrate and protein substances such as grains, seeds, maize, legumes, &c., the result being to lessen considerably the quantity of yeast and sugar required.  In the process preferably adopted coarse hominy, made from Indian corn, is cooked in water sufficiently to swell the grains, but allow them to be fairly dry and separate; it is then cooled to about 35 DEG  C. and treated with seeding stock prepared from the fungus-preferably aspergillus oryzae - by cultivation on moistened bread, or it may be on hominy, and subsequently drying and pulverizing.  The hominy, after inoculation, is well exposed to the air in thin layers on perforated trays and after completion of the growth is dried and ground to about the fineness of the flour used for the bread, and either in this form, or as an extract, is incorporated in the dough.

Abstract: 981,893. Ultrasonic testing; ultrasonic wave couplings. INSTITUT DE RECHERCHES DE LA SIDERURGIE FRANCAISE. Jan. 8, 1962 [Jan. 6, 1961], No. 621/62. Headings H4D and H4J. An ultrasonic test head of the kind in which coupling between the transducer and the testpiece is effected by means of a liquid comprises a structure consisting of a first " steady-flow " chamber 3 (Figs. 2 and 3), communicating via a first (main) aperture 7 (Figs. 1 and 2) with a second chamber 6 to which the liquid (water) is supplied via feed pipes 8a, 8b, the chamber 6, acting as a " smoothing " or " surge " chamber, being provided with a second aperture consisting of a small hole 9 (see Fig. 2), also communicating with chamber 3 which is provided with a small hole 10 (Fig. 2) opposite hole 9 and with an aperture 5 through which the liquid makes contact with the material 1 being tested. In operation, the chamber 6 acts to free the incoming liquid from turbulence, any trapped air bubbles rising to the top where they are discharged via holes 9 and 10 so that the main flow of liquid which couples the vibrations of the piezo-electric transducer 2 with the material 1 via aperture 5 is free from such disturbances. The whole assembly is mounted on two rollers 11a 11b by means of a clip 13 secured to a frame 12 by resilient means 14. The embodiment of Figs. 1 to 3 is intended for testing (scanning) long rolling mill products the surface of which is either vertical or sloping. In a second embodiment for scanning the horizontal underside of a test-piece (Figs. 4 and 5, not shown) the chamber 6 surrounds the chamber 3 which is provided with the aperture 5 only, air bubbles escaping through small holes in chamber 6 similar to the hole 10 in chamber 3 (Fig. 2). In both embodiments the bores of the feed pipes, the chambers 3 and 6 and the apertures 5 and 7 are such that almost the whole pressure drop is localized in the liquid film between the surface plate of the assembly (plate 4, Figs. 2 and 3) and the material 1 resulting in a steep radial pressure gradient which prevents air bubbles trapped by the relative motion of the test head and the material 1 from interfering with the measurement.

Abstract: 480,989. Moulding tubes from thermoplastic material. CELLULOID CORPORATION Jan. 8, 1937, No. 666. Convention date, Jan. 8, 1936. [Class 87 (ii)] [Also in Group XXVIII] A tube of thermoplastic material, e.g. material containing cellulose acetate or other thermoplastic derivative of cellulose, is produced by drawing a heat-softened strip of the material through a cooled tubular former of circular internal cross - section and simultaneously twisting it so as to cause it to be spiralled into cylindrical form, the edges of the strip being jointed by the application of a solvent or adhesive, by immersion or otherwise. and the tube being finally subjected to any desired finishing operation such as drawing, shaping by blowing, &c. The strip material may be formed from a number of different layers united together and may have any suitable pigment or other effect material incorporated therein. A suitable machine for making the tubes is shown in Figs. 1 and 3 and comprises a number of formers 6, to which strips 13 of the material are fed from a tank 1 containing heated liquid 2, and rods 16 for drawing the strips through the formers. Each rod is provided at one end with a coupling 69 for insertion through a hole in a strip 13 and is rotatably connected at the other end to a piston 15 adapted to reciprocate in a cylinder 14; the rod 16 is also provided with a helical groove 17 for engagement by a pin &c. 31 located in a bearing 28 through which the rod passes, the pin 31 being integral with a plug 32 and normally held out of engagement with the groove 17 by a spring 33. The piston 15 is actuated by compressed air &c. which is supplied to the cylinder 14 from a pipe 36 through a valve 45, this causing the rod 16 to be moved to the right to draw the strip ; simultaneously air is supplied to the plug 32 to cause the pin 31 to engage the groove 17 and effect rotation of the said rod. At the end of the stroke the rod coupling 69 actuates a lever 54, which opens the valve 45 to exhaust and opens a valve 44 to pressure air, to effect the return of the piston and withdrawal of the pin 31. Each former comprises an outer jacket which surrounds a metal forming tube 11 flared at both ends and is provided with cold water inlet and outlet pipes 12, and all the formers are preferably removably mounted on a support 7 so that one set can be replaced by another set of different size.

Title: An improved safety device for muzzle loading cannon
IPC: F41F1/06
Filed: 1927-01-10
Abstract: 264,493. Lafitte, T. Jan. 12, 1926, [Convention date]. No Patent granted (Sealing fee not paid). Ordnance, muzzle loading.-A trench mortar or gun of the kind in which the shell is inserted at the muzzle and drops to the breech by its own weight is provided near the muzzle with a rocking detent adapted to prevent a second shell from being inserted while the first is still in the barrel. As shown in Fig. 1, the detent comprises an escapement-like device formed by a two-armed lever 4 having a nose 9 at the top and a pivoted pawl 5 at the bottom, the nose and pawl registering with openings in the barrel wall so that, when the lever is rocked, either the end 9 or the pawl projects into the bore. When loading the gun, the lever is first in the position shown in chain lines with the nose 9 out and the pawl 5 in, and then to allow the shell to pass the pawl 5, the lever is rocked to the position shown in full lines, the end 9 then projecting into the bore to prevent the insertion of a second shell. A spring plunger 14 retains the lever in either of its positions. When the gun is fired, the gas pressure acts on a light piston 13 which pushes the top end of the lever outwards. Means may be provided for locking the lever in the operative position shown in Fig. 1, while the shell remains in the gun. As shown in Fig. 5, a spring catch 28 carried by a rod 31 connected to the firing mechanism is adapted to pass under the lower end of the lever 4. The firing mechanism comprises a spring plunger moved and released by a cam 37 rotated by a handle 36. The rod 31 is connected to the firing plunger so that when the gun is fired the catch 28 is pulled down to release the lever 4, the catch being restored to its operative position when the firing handle is turned to its initial position. In a modification, the lever is locked by a sliding rod moved to the operative position by the weight of the shell.

Abstract: 545,267. Dust separators. HABER, E. J. Aug. 13, 1940, No. 785/41. Divided out of 535,573. [Class 23] [Also in Group XXVIII] Gases of different densities are separated, or suspended matter is separated from gas, during its passage through apparatus having convergent passages with slotted walls 4 arranged between the top and bottom plates of a chamber 1; arrangements are made to recirculate the gas accompanying the heavier separated component. The walls 4 are of sheet metal and the slots 5 are formed by pressing parts outwards. The converged ends of each pair form narrow passages communicating with vertical passages 9 which open into the hopper 11 below the chamber 1. The hopper has a central baffle 12 and openings to passages 14 on the side the baffle remote from the passages 9 by which the gas can be recirculated. The complete separator is built up of a number of similar units, two such units being shown. The mixture enters the inlet 2 and passes to the space between the slotted walls 4; the clean gas or the lighter component passes through the slots 5 to the entrance of the next section while the dust or heavy component passes to the passages 9 and the hopper 11. Here the dust is left and the gas passes to the passages 14 to join the mixture passing between the walls 4. In a modification this recirculating gas is brought through a passage 30, Fig. 2, to join the clean gas passing to the next section. The openings to the passages 14 may be varied in size by dampers 17 operated by hand screws 19. The discharge of dust from the hopper 11 is controlled by two valve plates 21, 22 on pivots 24, 25. These valves are operated by a hand lever 28 through a linkage which permits only one valve to be open at one time.
