Title: Improvements in and relating to the control of electric motors for driving presses
IPC: B30B15/14
Filed: 1951-04-05
Abstract: 690,846. Control of A.C. motors. MASCHINENFABRIK WEINGARTEN AKT.-GES. April 5, 1951 [May 2, 1950], No. 7910/51. Class 38(iii) [Also in Group XXXIV] The stamper 2 of a press is raised and lowered by means of a nut 3 and spindle 4 to which is fixed: a flywheel 7 driven through a spring-pressed friction roller by a squirrel cage induction motor 10. The flywheel has brake blocks 9, 9a, which are controlled by means of compressed fluid supplied to cylinder 16 under the regulation of a valve 21 actuated by electromagnet 20. The motor 10 has a doublehandled controller HI, H2, which occupies the position shown when the press is at rest. Closure of a safety switch M energises the control circuit and starts a ventilator motor V which cools the main motor. The brake may be released by moving the controller to position 41, 41a, so closing contact Cl and energising relay C to render coil 20 effective. The stamper can then slide dowardly owing to its own weight. Moving the controller to position 42, 42a, closes contact A1 in addition to contact C1 and the relay A switches on the motor 10 for downward movement. Cam operation of switch E2 limits downward movement by de-energising relay A, the relay B being energised for upward operation of the press. After remaining for a short period in the position 42, 42a, the controller may be released to return automatically to the position 40, 40a, the press continuing its upward travel. The press is stopped during its upward movement by returning the controller to position 42, 42a, whereupon a time-delay relay Z1 is energised to render effective a relay D after a pre-determined period so opening relay B. If the controller is retained in this position the press again moves downwardly. Upon operation of an upper limit switch E1 the relays B and C are deenergised to stop the motor and apply the brake. If, due to faulty operation, the press should travel beyond the point at which the switch E1 is operated, an over-run switch E3 is actuated to reverse and stop the motor. The brake is released for upward movement by actuating the controller to position 43, 43a, raising operation of the motor being effected by positioning the controller at 44, 44a, so energising relay B. After upward movement of the press has started the controller is allowed to return to position 40, 40a. Continuous upward and downward motion of the press is instituted by closing switch H. The press is halted at the upper limit position for a period determined by time-relay Z2 and is automatically reversed at the lower limit.

Title: Improvements in hydraulic brakes for vehicles
IPC: B60T8/18
Filed: 1945-03-29
Abstract: 628,317. Fluid-actuated valves. SOC. ANON. A. CITROEN. March 29, 1945, No. 7945. Convention date, May 8, 1943. [Class 135] [Also in Group XXXIV] A valve device for regulating the pressure applied to vehicle brakes in accordance with the wheel load is controlled by a lever, the arms of which are respectively subject to the supply pressure set up in a hydraulic master cylinder and to that in the brake cylinders between which and the master cylinder the device is interposed, the fulcrum of the lever being adjustable by the deflection of the vehicle suspension springs. Pistons 21, 24 engage a lever 3 fulcrumed on rollers 25, 27, carried by link 28 from a lever 32 pivoted at 31 and connected by a link to a wheel axle so that the position of the fulcrum is dependent upon the wheel load. A passage 24a through piston 24, which is open at one end to a reservoir in the casing A, is normally closed at the other end by engagement of the reduced end of the piston with the resilient head 35a of a valve 35 which is normally seated at 36 on a fixed part. Pressure liquid supplied by a master cylinder connected to passage 38 acts on piston 21 and through lever and piston 24, to unseat the valve head 35a so that the liquid flows through passages 39a, 39 to the brake cylinders until the pressure therein acting through passage 39b on valve 35, the piston 24 and the lever 3 balances the master cylinder pressure acting on piston 21 and re-seats the valve head 35a. If the master cylinder pressure is reduced, the pressure in passage 39a acting on the reduced end of piston 24 unseats this end from the valve head 35a, permitting flow from the brake cylinders through passages 39a, 24a to the reservoir A, until the pressures acting on the lever are again balanced. A non-return valve 33 permits the return of liquid from the reservoir A to the master cylinder. The fulcrum for the lever 3 comprises a pair of rollers 25 mounted one at each side of a central roller 27 on a pivot 26 carried by the link 28. The lever 3 bears on the outer rollers 25 but these do not bear on the casing wall C. The roller 27 bears on the wall C but not on the lever which is grooved to receive this roller. The rollers are thus free to rotate in opposite directions as they travel along the lever.

Title: Improvements in or relating to process for recovering glutamac acid
Filed: 1956-03-16
Abstract: Glutamic acid is obtained from waste liquors containing precursors of glutamic acid (e.g. pyrrolidonecarboxylic acid) which are obtained after removal of sugar from beet molasses and which have a dry solids content of between 25 and 55 per cent by weight, by hydrolysing said liquors with barium hydroxide at an elevated temperature, adding to the resulting hydrolysate a compound which forms a water-insoluble salt with barium, and crystallizing and recovering glutamic acid from the resulting solution.  The waste liquor may be barium filtrate, Steffen's filtrate or vinasse.  The hydrolysis step is preferably carried out at a temperature of between 65 DEG  and 100 DEG  C. Compounds forming insoluble salts with the barium are preferably carbon dioxide, sulphur dioxide, sulphuric acid and alkali metal carbonates, bicarbonates and sulphites, these compounds being added until a pH of between 8.0 and 12.0 is reached.  The barium-free hydrolysate may be adjusted to a pH of 3.2 with, for example, sulphuric acid and glutamic acid crystallized therefrom or, alternatively, using stronger acid, the glutamic acid may be recovered in the form of its acid salt, for example the hydrochloride.
