Title: Devices for use in inflating tyres of motor vehicles
IPC: B60C23/14
Filed: 1974-01-18
Abstract: 1456137 Valves; pipe couplings ROBERT BOSCH GmbH 18 Jan 1974 [20 Jan 1973] 02570/74 Headings F2V and F2G In a device for inflating tyres from the compressed air supply of a vehicle braking system, the pressure regulator of the system incorporates a change-over valve operated when an inflation tube is attached to a connector. In the normal position of the valve closure member 7 compressed air from a compressor 3 passes through the regulator to a chamber 8 and thence to an outlet for connection to an air reservoir 4 which feeds the brakes via a control valve 5. When an inflation tube is attached to the connector 14 a hollow plunger 16 presses a planar surface of the closure member 7 into contact with a seating 12 to cut off the air supply to the reservoir 4 and at the same time its spherical surface 9 leaves its seating 11 to open up a supply of compressed air to the connector for inflating the tyre. In an alternative embodiment, Fig. 2 (not shown), the closure member incorporates a spring-loaded pressure relief valve which will open to feed air to the reservoir 4 should pressure at the connector exceed a predetermined value. In another alternative embodiment, Fig. 3 (not shown), the planar sealing surface of the closure member is replaced by a plug extension (31) bearing an annular seal (32) which cooperates with the inside wall of the passage leading to the reservoir connection. In a further embodiment, Fig. 4 (not shown), the closure member (47) has an annular extension (41) with an internal sealing lug (42) which engages the outer wall (43) of a hollow cylindrical extension (44) of the housing.

Filed: 1955-01-28
Abstract: <PICT:0778737/III/1> In the production of ammonium sulphate by the absorption of ammonia in a sprayed aqueous ammonium sulphate solution containing sulphuric acid and recycling of the solution to the absorption zone, ammonia-containing gas, e.g. coke oven gas, is passed upward through an absorption zone, the upper portion of which is sprayed with an acidified ammonium sulphate solution of relatively high sulphuric acid content at a relatively high volumetric rate of flow and the lower portion of which is sprayed with an acidified ammonium sulphate solution of relatively low sulphuric acid content at a relatively low volumetric rate of flow.  The volumetric rate in the lower portion may be at least 12 times that in the upper portion. The solution sprayed into the lower portion may have an acid concentration of not less than 7 per cent and that sprayed into the upper portion not greater than 3 per cent.  As shown coke oven gas is passed upward through an absorption vessel 1 from inlet 3 to outlet 4 while acidified sulphuric acid solution is sprayed through nozzle 6 in the upper portion of vessel 1, and through nozzles 7, 8 and 29 in the lower portion of the vessel.  After the absorption step the solution passes to a crystallizer and classifier tank 17 from which liquor and relatively large crystals are withdrawn through pipe 20 for the recovery of ammonium sulphate while liquor and relatively small crystals are withdrawn through pipe 24 and recycled to the absorption zone via nozzles 7, 8 and 29 optionally after the addition of acid.  Liquor and entrained crystals also overflow through pipe 16 into a tank 13 which is fed with make-up acid through pipe 30 and ammonium sulphate liquor separated from the gas passing out of the absorption zone through pipe 12.  The liquor in tank 13 is recycled to nozzle 6 via pipe 14a.  Solution may be passed through the nozzle 6 at 70 gal./min. and may have an acid content of 8-9 per cent. Solution may be passed through nozzles 7, 8 and 29 at rates of 1200, 1200 and 60 gal./min. respectively, and may have an acid content of 2-3 per cent. According to Figs. 2 and 3 (not shown) there may be provided an annular trough in the upper part of the absorber together with a star-shaped obstructor between the nozzle and the trough to deflect the liquor from nozzle 6 into the trough.  The liquor collected in the trough is passed to tank 13.  According to Fig. 4 (not shown) there is provided an annular trough together with an additional nozzle for supplying liquor from tank 13 upward through the trough.

Filed: 1944-02-12
Abstract: 577,221. Dehydrating and cooling foodstuffs. WEERTH, H. K. DE. Feb. 12, 1944, No. 2625. Addition to 560,954. [Classes 34 (ii) and 64 (ii)] [Also in Group VI] Foodstuffs &c. can be cooked, dehydrated or cooled in an outer chamber a containing a central perforated rotatable drum b having a helical rib 6 and stirrers 7 to churn up and feed the foodstuff along from a hopper 3 to an outlet 4, the central drum being supplied with steam through a conduit 12 and perforated pipes 13 or supplied with cooling air or fluid through a, conduit 38. The chamber a is connected at each end by ‹conduits 15 and 16 to a suction or pressure fan 17. A hood 27 from the chamber a leads through openable shutters 30 to a chimney 29. An alternative exit 42 is also provided. A tank c at the bottom receives meat &c. juices which are re-delivered by a pump 22 to the foodstuff. The perforated drum B is rotated by gears 10 and 11. The fixed chamber a is provided with a cover 2 and has perforated walls 1 forming lateral chambers 25, capped by filters 26 leading to the hood 27. Any meat products which pass through filter 26 may be trapped by partitions 34. A crank handle 32 moves the shutters 30. Cleaning doors 35 are provided in the base. A comb 37 scrapes off the foodstuff from the rotating drum B, the comb being able to be turned over to inactive position. During cooking the vapours are accumulated in a pressure atmosphere due to the resistance offered by the filters 26 and the closing of the shutters 30 depending upon the required treatment. When the product is cooked the steam 12 is cut off, the fan 17 is started to dehydrate the product by compression or suction driving air through the product. If by compression, the fan drives compressed air through the hollow centre of the drum b and out through the perforations therein and through the food itself and then through the perforations in the side walls 1. The used air is passed through filter 26 and hood 27, shutters 30 and chimney 29. In dehydrating by suction a vacuum is caused in the central portion of the drum b, so that suction air is passed in the reverse direction. If the treated product is to be canned or packed immediately, refrigeration may be supplied so that after dehydrating the product is cooled to the required temperature, the drum being rotated alternately or constantly in one direction to speed up the process. During cooling, instead of using the chimney as an outlet the used air &c. passes through the valve 43. For discharge a door 41 in the outlet is opened and the helical rib 6 conveys the product to the door. Cooking may take place first at a temperature of 150‹C., 90 per cent. relative humidity and an air to product ratio of 20 : 1 and may be finished off at a temperature of 70‹C., humidity 20 per cent. and ratio of 5 : 1, such change being gradual and controlled. Heating means are provided for the air supplied to the apparatus.

Abstract: 538,913. Cellulose esters. BRITISH CELANESE, Ltd. (Celanese Corporation of America). Feb. 20, 1940, No. 3190. [Class 2 (ii)] Cellulose is esterified with the aid of a fatty acid anhydride in presence of more than 9 per cent based on the weight of the cellulose of a polybasic inorganic acid catalyst so that the cellulose ester is produced in solution. The amount of acid catalyst is then adjusted by addition to the liquor of a neutralizing magnesium or zinc compound to a value of less than 9 per cent and thereafter the cellulose ester is ripened. The cellulose may be pretreated with acetic or formic acid containing, if desired, a small amount of catalyst. The acetylation may be effected at temperatures up to 45‹ C. Ripening may be carried out at 30‹-65‹ C. and it may be a continuous process, the mixture travelling slowly through a conduit of appropriate length. The catalyst may be sulphuric acid or phosphoric acid. Magnesium acetate or carbonate or zinc acetate or oxide may be used for partially neutralizing the catalyst. The process is applicable to the production of cellulose acetate, propionate, butyr ate, or other ester or mixed ester. The cellulose esters may be used in the production of filaments and films. The water required for ripening may be added in stages and it may be added in the form of dilute acetic acid.
