Title: Process for the production of 2,5-dihydroxyterephthalic acid
Inventor: ZORN HERMANN
IPC: C07C51/15
Filed: 1965-09-01
Abstract: 2,5 - Dihydroxyterephthalic acid is prepared by the action of carbon dioxide at a raised temperature and pressure on an alkali compound of hydroquinone or a mixture of hydroquinone and one or more alkali compounds, the reaction being effected in the presence of an inert solvent and/or in the presence of a limited proportion of water, e.g. 1.2-2.8 mols. per mol. of hydroquinone.  Hydrocarbons are the preferred solvents, a number being specified.  The reaction is effected at 160-240 DEG  C., suitably under a carbon dioxide partial pressure of 20-110 atm. The product may be purified by way of the dipotassium or diammonium salt, either of which is easily soluble in hot water but only moderately soluble at room temperature. Addition of a reducing agent, e.g. sodium bisulphite, during the purification is advantageous, or alternatively the purification may be effected in an oxygen-free atmosphere.  Examples are given.

Title: Spring Brake Systems.
Inventor: MORGAN EDWIN FREDERIC REYNOLDS
IPC: B60T15/04
Filed: 1966-08-22
Abstract: 1,174,424. Spring operated brakes. WESTINGHOUSE BRAKE & SIGNAL CO. Ltd. 26 July, 1967 [22 Aug., 1966], No. 37466/66. Heading F2F. In a spring-applied pneumatically-released braking system the manual control valve is in the form of a housing comprising separate upper and lower parts 2, 3 respectively, separated by spacer 4 and surmounted by a rotatable cap 5 carrying an operating handle 6. Rotation of handle 6 causes longitudinal movement of a member 8 by the action of cam surfaces (not shown) formed on members 8, 9; member 8 carries a stop collar 10 in contact with which is spring 11. A slidable piston member 12 is kept in contact with the other end of spring 11 by means of a further spring 23; an extension 14 of piston member 12 carries a valve seat 15 which in conjunction with closure member 16 forms an exhaust port. A further fixed valve seat 17, forming with closure member 18 an inlet valve, is connected to compressed air inlet port 20. Inlet valve 17/18 is biased to the closed position by spring 21 urging a retaining ring 22 against closure member 16. Over the major part of the rotation of handle 6 the arrangement acts as a self-lapping valve giving a steadily increasing pressure in chamber 24 connected to the brake cylinder: toward the end of the downward travel of member 8, however, stop collar 10 comes into engagement with extension 14 of piston member 12. Thereafter piston member 12 is forced rapidly downwards closing valve 15, 16 and opening valve 17, 18 to bring the pressure in chamber 24 up to the maximum supplied pressure: the operating point at which this occurs may be chosen by selection of the thickness of spacer 4. The arrangement is described as applied to a braking system in which the brake cylinder is double ended, the one end providing for "emergency" operation under spring control, with release via a control valve of the type described. The other end provides for normal "service" operation under pneumatic control via a separate control valve, each control valve being provided with its own reservoir (Fig. 1, not shown).

Title: Improved construction of lock for motor road vehicles
IPC: B60R25/021
Filed: 1929-12-12
Abstract: 343,236. Preventing unauthorized use of motor vehicles. JOHNSON, C. W., 16, Sibthorp Street, Lincoln. Dec. 12, 1929, No. 38123. [Class 79 (iii).] A permutation steering-wheel lock for preventing unauthorized use of a motor vehicle comprises a plate 12, secured by bolts 15 to the underside of the steering wheel 10, with an annular series of pins 14 adapted to be engaged by a locking assemblage of radially-slidable spring-pressed bolts 23 in a non- rotatable carrier member 20 slidable on the fixed steering pillar 11. When the carrier member 20 is pushed upwards, the pins 14 pass through apertures 21 in its upper face and also through apertures 23d formed in the bolt members 23. The majority of the apertures 23d are in alignment with the pins and only effect locking engagement when the bolts are pressed radially inwards. A few of the bolts, however, are provided with apertures out of alignment which snap over the heads of the pins and effect locking engagement until the bolts are pressed inwards. Release can therefore only be effected by pressing inwards the correct combination of bolts 23. The bolts, which are interchangeable to vary the combination, are retained in the recesses 22 by a cover-ring 26 secured by screws and which can only be removed when the member 20 is in the lower, unlocked position. The bolts 23 comprise in addition to the projecting heads to allow of manipulation, disc-shaped parts 23a, 23b united by a flat web 23c in which the apertures 23d are formed. The sleeve portion of the member 20 may be slidably keyed directly to the steering pillar 11 or, as shown, to a sleeve 16 secured to the pillar by screws 17 and provided with a flange 19 with which a spring catch 29 on the member 20 engages to retain the locking device in the out-ofuse position. Alternatively the relatively slidable parts may be non-circular.

Abstract: 1,096,674. Current collectors. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Sept. 21, 1964 [Oct. 1, 1963], No. 38643/63. Heading B7L. The lower levers 1 of a system 1, 3, 17, 19 supporting a current collector 9 are fixed to shafts 13 pivoted to side members 5 of a frame which is attached to a vehicle; springs 23, 24 connected to shafts 13 bias the collector 9 upwardly against a conductor. A spring 25 acting through levers 26, 27, on a cam 28 on shaft 13, can force the arms 1 apart against the action of springs 23, 24 to lower collector 9; normally, however, spring 25 is overcome by a pneumatic cylinder 29 acting on lever 26 to move lever 27 just clear of cam 28. Air is supplied to cylinder 29 from pipe 32, Fig. 2, through electrically controlled valve 33 and emergency valve 35, an operator being able to control valve 33 to vent or pressurize cylinder 29 to lower or raise collector 9. Should the collector rise above a certain elevation due, for example, to it leaving the conductor, then a lever 57, Fig. 2, fast with shaft 13 moves the spool of valve 35 to vent cylinder 29, whereby spring 25 lowers collector 9. Valve 35 stays in the venting position until valve 33 is also moved to the venting position.
