[Also in Division G1] A device for indicating the interior pressure of a pneumatic tyre comprises a hollow body 1, means incorporating an inflatable member 5 disposed in the hollow body, the interior of the inflatable member being in communication with the interior of the tyre to indicate the air pressure inside the tyre and means for inflating the tyre through the body 1. In the embodiment shown in Fig. 1 compressed air is supplied to the cap 15 which opens valve 16 and compressed air flows through passages 10a, 9a into inflatable member 5 forcing tubular piston 5d outwardly. The air then passes into the tyre through the nozzle 6 and air valve 3 of the tyre. When the compressed air charging nozzle is removed valve 16 closes and the tubular portion 5d is brought into tight contact with pipe 9, thus preventing air in the inside from leaking. The inflatable member 5 is inflated progressively from the pressure within the tyre with the result that the piston 4 is moved upwardly, its position being related to the pressure in the tyre and being determinable by the marking 19 visible through window 18. Various other embodiments are described with means for cutting off leakage through the device should the pressure in the tyre become low and with further means for indicating the pressure in the tyre by the position of a valve member in a transparent cap.

Title: Process for controlling the odour or flavour of edible oils and fats
IPC: C11B3/00
Filed: 1937-12-14
Abstract: 513,514. Purifying fatty oils ; shortening agents. RENNER, H. O. Dec. 14, 1937, No. 34656. [Class 91] Oils and fats are freed from undesirable odour and flavour by treating with an enzyme originating in micro-organisms, under conditions to avoid fermentation. Impurities removed consist mainly of cleavage products of unsaturated glycerides, short chain aldehydes, high molecular aldehydes, keto-compounds formed from proteins, and volatile carboxylic acids. Fatty oils treated are, peanut, cottonseed oil, lard, or the enzyme-oxidized oils described in Specification 423,971. Bacteria, yeast, moulds ; yeast or mould juices ; autolysates, or plasmolysed yeasts are used. About 2 per cent. of a plasmolysing agent such as sodium chloride, glycerine, sugar, or calcium chloride solution is used. The treating conditions are controlled to avoid fermentation by adjusting pH value to about 6.5 by keeping the reaction period short, adding neutralising agents, or by pasteurization before treatment. In examples, (1) peanut oil is mixed with an equal amount of water at 24‹C. and plasmolysed compressed yeast is added with stirring for 4“ hours, while increasing the temperature to 35‹C. After standing at room temperature, the treated oil is separated by centrifuging. (2) An enzyme-oxidized peanut oil made by the process described in Specification 423,971 is treated with water and plasmolysed yeast at 24‹C. 'for 5 mins., the pH value being maintained at 6.5. The oil is separated, and is unchanged in peroxidized oil content. (3) An enzyme-oxidized peanut oil is mixed with dilute calcium chloride solution containing enzyme-active soya bean flour, the mixture being of pH value 5.5, is pasteurized by agitating at 65‹C. for “ hour, and then cooled to 37‹C. Plasmolysed yeast is added and the mixture maintained at 26-49‹C. for 17 hours. A small amount of urea, sodium carbonate, secondary sodium phosphate, or sodium hydroxide is, added to bring the pH value to about 7. The mixture is then gasrefined by blowing in air or carbon dioxide at 30‹C. for about 1 hour. The oil is then separated in a centrifuge. The bland oils obtained may be used in bakery products as shortening or dough-bleaching agents.

Title: Improvements in the manufacture of electric incandescent lamps or the like
IPC: H01K3/28
Filed: 1928-11-26
Abstract: 301,389. General Electric Co., Ltd., (Assignees of Patent-Treuhand-Ges. f³r Elektrische Gl³hlampen). Nov. 28, 1927, [Convention date]. Discharging and feeding devices for endless-belt conveyers and elevators - Apparatus for feeding the bulbs of incandescent lamps to a sealing-in machine comprises a vertically movable gripper adapted to lift the rows of bulbs from a tray and transfer them to a slide' from which they are delivered one at a time to the machine. The apparatus is shown in perspective in Fig. 3. The trays. carrying the bulbs 7 are supported on juxtaposed ledges 5 of two endless intermittently operated conveyers 2. A gripper device comprising two parallel rails 11 carried by pivoted spring-controlled arms 10 on a rod 8 moves downwards by its own weight about a pivot 70, is guided by an arcuate groove 68 so as to engage a row of bulbs and is lifted by a vacuum-actuated piston rod 64 and rope 65 so as to allow the bulbs to slide down parallel guide rails 15. An escapement device consisting of two fingers 29 allows the bulbs to pass singly from the guides. The fingers are carried by a lever 28 fast to a shaft 25, which is rocked by a vacuum-actuated piston rod 24, lever 26 and spring 27. A push rod 35 opens a gravityoperated clamp on the sealing-in machine to receive the bulb and is actuated from the escapement device by the slotted lever 23. In order to align the rows of bulbs with the gripper, the tray is given an intermittent transverse movement equal to the spacing ofthe rows. This movement is obtained by a lever 13, with a gravity pawl device 14 engaging successive meshes of the tray. The lever is actuated by the vacuum device 59, rod 60, and spring 62. The movement of the conveyer to bring successive trays into position is obtained by a shaft 84 having bevel gearing engagement with the conveyer wheels 3, and actuated by the vacuum device 79, weight 83, rope 82, and pulley 81, which has a free-wheel connection with the shaft 84. All the vacuum devices are in communication with a common vacuum pump 21 and are suitably timed. A cam 47 on the shaft of the sealing-in machine opens the valve 46 of the escapement device when the lamp holding device of the machine is in position. The valves 54 and 56 controlling the tray-traversing and gripper devices are actuated by cams 52, 53 on a shaft 48 actuated from the escapement device by a pawl 50 and ratchet wheel 49 having a number of teeth corresponding to the number of lamps in a row. The conveyer controlling valve 76 is opened by a cam 75 actuated from the tray traversing device by a pawl 73 and a ratchet wheel 72 having a number of teeth corresponding to the number of rows in the tray. The empty trays ejected bv the transverse movement are moved over side supports into a receptacle attached to the frame of the apparatus. Alternatively mechanical means may be used for actuating the. parts, and the gripper may be displaced parallel to itself in a vertical plane, in which case the bulbs are transferred to the guides by means of a pusher device.

Abstract: 1,199,057. Filter beds. UNION TANK CAR CO. 31 July, 1967 [24 Aug., 1966], No. 34988/67. Heading BID. A filter bed 12 is located in closed tank 13 and supplied with raw liquid through box 40, containing overflow 38, and lines 36, 30, with valve 62 closed, and automatically backwashed in three stages when the pressure in chamber 26 upstream of bed 12 is sufficient for liquid to rise up tube 54 to probe 58. Filtered liquid normally flows out of tank 13 through duct 48, over weir 88 in closed vessel 91 and through duct 49 to filtrate reservoir 20, from which it discharges by outlet 50. Alternatively, line 50 may connect directly to duct 49 at high level, so that once reservoir 20 is full the filtrate bypasses it. Liquid contacting probe 58 closes electric switch 56, which opens valve 62 and starts air blower 70. Blower 70 first forces liquid from vessel 91 back through the bed 12, then supplies air behind it agitating the bed. An air cushion 21 is maintained above the liquid in chamber 26 by vent 75, air being entrained during filtering at weir 38, and filter medium is separated from the reverse-flow air which discharges through vent 75 and/or lines 30, 34. Baffle 32 shields line 30. Timer 72 cuts blower 70 after a predetermined interval, enabling the contents of reservoir 20 to flow back through bed 12 to waste through valve 62 (Fig. 4, not shown). Finally, valve 62 is closed by a second switch 66 actuated when the level of reservoir 20 falls below probe 68, and filtering begins again. The filter bed could be backwashed with other than filtrate liquid, and with oxygen or nitrogen instead of air.
