[Class 116.] Apparatus for supplying measured quantities of liquids to different customers each provided with a different key has a rotatable disc 5 carrying several locks 6 e a c h having a counter 7, operated by a projecting tongue 8, the disc being turned by the customer until the lock allotted to him is in front of a bolt 18 whereupon the key is inserted to lift the bolt thus freeing a rod 11 connected with the operating lever of the liquid delivery device and locking the disc 5 against rotation. The casing 1 of the device has a lower extension 2 and carries a fixed pin 4 on which the disc 5 is freely mounted. A member 10 slidable within the extension 2 is connected with the rod 11 and carries a spring-pressed roller cam 14 adapted to operate the feed tongue 8 of the counter 7 corresponding to the selected lock. The bolt 18 is urged towards the carriage 10 by springs 19 and is provided with two projections 20 one or other of which normally engages a projection 15 on the member 10 to prevent the rod 11 being moved. Each lock 6 has at the back a cam finger 21 which can be turned through 180‹ by the key to engage the top of a recess 22 in the bolt and lift it thus freeing the rod 11, allowing the liquid delivery device to be operated and simultaneously locking the disc 5 by a tooth 24 on the bolt engaging one of a series of recesses 23 on the periphery of the disc. To ensure that the disc 5 shall be set correctly a spring- pressed cam 25 engages with the opposite recess 23. While filling the key cannot be withdrawn from the lock.

Title: Improvements in the manufacture of esters of cellulose or of its transformation products or of other carbohydrates
IPC: C08B3/00
Filed: 1930-07-21
Abstract: A modification of the process described in the parent Specification for the esterification of cellulose, or of a transformation product thereof, or of another carbohydrate in the presence of liquid sulphur dioxide, consists in carrying out the reaction under an increased pressure above that due to the use of the liquid sulphur dioxide. The additional pressure may be obtained by the introduction of an inert gas such as compressed air or nitrogen, and a limited quantity of an oxidizing agent such as described in Specification 343,655, may be present if desired. In examples: (1) cotton linters are acetylated by means of acetic anhydride in liquid sulphur dioxide, the pressure being maintained at 12 atmospheres by the introduction of nitrogen; sulphuric acid is used as the catalyst.  (2) lignocellulose is treated with a mixture of acetic anhydride, propionic acid, sulphur dioxide, and sulphuric acid under a pressure of 12 atmospheres produced by means of nitrogen, the product being cellulose acetopropionate.  (3) starch is treated with a mixture of acetic anhydride, sulphur dioxide and sulphuric acid under the conditions stated for example (2); acetyl starch is obtained.  The subsequent after-treatment (hydrolysis) of the carbohydrate esters may likewise be carried out under an increased pressure.

Title: Discharge lamp arrangement
IPC: H05B41/04
Filed: 1974-05-17
Abstract: 1437764 Control systems for gas discharge lamps PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 17 May 1974 [21 May 1973] 22053/74 Heading H2H An arrangement for igniting and operating a gas discharge tube comprises means for generating high voltage pulses during the lamp operation so as to ensure re-ignition of the lamp in the event of the tube being extinguished. A low pressure sodium or mercury vapour lamp 5 is supplied from an A.C. source 1, 2 by way of a series connected choke ballast 3. Connected in parallel with the lamp 5 is a diode bridge 9-12 across the D.C. terminals of which is connected a transistor 13. The control circuit for the transistor 13 includes a capacitor 15, chargeable from the bridge output by way of a resistor 14, and a diac 16. When the capacitor is charged sufficiently the diac 16 breaks down and the transistor 13 becomes conductive. The capacitor 15 discharges by means of a resistor 17 until the diac 16 recovers and the transistor 13 goes non-conductive. Thus, the choke 3 causes a high voltage pulse to appear across the lamp 5 which would cause re-ignition thereof if necessary. The time constant of the components 14, 15 is such that a plurality of high voltage pulses are produced during each cycle of the A.C. supply. If the control circuit does not include a diode bridge, two transistors may be used in reverse-parallel, each being provided with its own control circuit. In a further embodiment a control circuit which includes a thyristor is also connected in parallel with the lamp to provide the pulses for the initial ignition of the lamp, and this circuit may include a negative temperature coefficient resistor.

Openers etc.; feeding openers &c.-In a machine for disintegrating textile waste such as woven or knitted fabrics, yarns, cords. &c. to produce a long staple lint, the waste is fed to a cylinder 7, covered with long bristles 10 of steel wire or other resilient or springy material, which cooperates with a yieldable presser plate 54, and two cylinders 56, 58 covered with short metallic bristles. The feeding device comprises a belt 4, a pair of feed rollers 18, 24, and a pair of gripping- rollers 19, 25. The roller 19 is provided with a serrated surface, and the other rollers may be covered with rubber &c. The upper rollers are carried by a sliding bearing 21 controlled by springs 23. The presser device is supported by rods 45 slidably mounted in the framework, and is kept up to its work by springs 53 adjusted by nuts 51 on the ends of the rods. A lip 55 on the presser-plate prevents escape of the material under the roller 19. The cylinders 56, 58 are cleaned by a brush 60 with long metallic bristles. The lint produced passes out between rollers 66, 67 on to a discharge belt 68. The operative cylinders are driven by belt gearing from the main shaft 11. The feed roller 18 is driven at an adjustable speed through worm gearing 36, 37, and a belt 31 running over cone drums 29, 30. The gripping roller 19 and the belt 4 are driven by belts from the roller 18. The discharge apparatus is driven by a belt 16 from the main shaft. Specification 155,195 is referred to.
