Patent GB-962684-A (GB)
Title: Fermentation process for preparing l-glutamic acid
IPC: G01N33/487
Filed: 1962-06-06
Abstract: A process for the production of L-glutamic acid comprises culturing microorganisms capable of producing L-glutamic acid in a nutrient medium containing assimilable carbon and nitrogen sources, while shaking under aerobic conditions, at a temperature at which multiplication of the microorganisms takes place, subsequently feeding a 44-49g/dl. sugar solution to the culture medium and recovering L-glutamic acid. Preferably the medium is heated to 34-38 DEG C. before, during or after feeding the sugar solution, and the sugar solution is preferably added after the carbon source has decreased by 30-54% by weight.  Sugars are defined as glucose, fructose, maltose, sucrose and starch hydrolysate; molasses solution is used in one example. Preferred microorganisms belong to genus Brevibacterium, genus Bacillus, genus Micrococcus or species Escherichia coli.  Specifications 873,448, 876,943, 889,187, 905,973, 920,241 and 920,242 are referred to.

Abstract: 460,715. Aerials. PIONEER INSTRUMENT CO., Inc. Aug. 2, 1935, No. 21957. Convention date, Aug. 4, 1934. [Class 40 (v)] The trailing aerial 20, Fig. 1, of an aeroplane is housed inside a tube 5, from which it is both thrust out and drawn back as required by pneumatic pressure or suction. An airpump 9 driven from the engine of the craft is connected by conduits 14, 15 to the end of the tube 5 nearest the cockpit, and exerts pressure or suction, under the control of valves 17, 18 operated by the pilot, on a piston 19, Fig. 2, so as to force the aerial out or draw it in. In its retracted position, the aerial is disconnected from the wireless set 22, Fig. 1 ; but as it is forced outwards, a ball 23 comes against a contact 24 at the far end of the tube 5, and connects the aerial to a lead 25 from the set. To save space, the housing- tube 5 may be coiled up near the cockpit, instead of extending fore and aft of the machine.

Title: Improvements in or relating to methods for the induction heating of metals, with recovery of the energy that is dissipated within the inductor, and heating equipments operated according to such methods
IPC: H05B6/02
Filed: 1965-05-26
Abstract: Workpieces are induction heated, e.g. steel billets to 1200 DEG C or aluminium ingots L to 500 DEG C., by applying A.C. to an inductor coil 10 e.g. of <PICT:1063189/C6-C7/1> copper tubing in a heating unit Ri, cooling the coil e.g. to 250-300 DEG C. by heat exchange with a fluid which is then used to preheat the workpieces, e.g. to 200 DEG C. in an heat exchanger Pr comprising a salt bath 12 or other liquid, before inductively further heating them in the coil.  The fluid, which is preferably circulated in a closed circuit through the inductor coil and pipes in the heat exchanger, may remain in its liquid state at the temperature attained by taking up heat from the inductor, or be converted into its vapour state and then brought again to its liquid state at the temperature of heat exchange with the workpieces.  Alternatively a gaseous fluid such as air may be used.  Examples of cooling fluids are eutectic mixtures of diphenyl and diphenyl oxide, water and salt baths.  The workpieces may be automatically advanced through the heat exchanger by a conveyer chain, then through the inductor by a hydraulic piston 16, the temperature attained by the workpiece controlling the operation.

Title: Improvements in and relating to automatic lathes
IPC: B23B13/00
Filed: 1935-08-09
Abstract: 443,136. Automatic lathes. PITTLER WERKZEUGMASCHINENFABRIK AKT.- GES., Wahren, Leipsic, Germany. Aug. 9, 1935, No. 22562. Convention date, Dec. 5, 1934. [Class 83 (iii)] An automatic stop device for a lathe operating on bar material 1 comprises a detector 2, normally engaging the bar material, and a constantly reciprocated pawl 4 which is brought into engagement with a toothed wheel 5 when the dectector no longer engages the bar material, the toothed wheel rotating step-by-step and having, adjustably secured thereto, a disc 16 provided with a peripheral recess into which a spring-urged lever 22, Fig. 3, controlling the disengagement of the main clutch, enters so that after a predetermined angular motion the main clutch of the lathe is actuated. The detector 2 holds the pawl 4 out of engagement with the toothed wheel 5 by a link 3, the pawl being constantly reciprocated by an adjustable eccentric pin 11 through a bell-crank lever 12 pivoted at 13. The eccentric pin is carried on the end of a shaft 7 which is disconnectably coupled to the cam shaft 8 of the lathe. The toothed wheel 5 is concentrically mounted relative to the shaft 7 but is not connected thereto, being keyed to a disc 15 which carries the adjustable notched disc 16. A spring- pressed detent 21, Fig. 3, carried by the lever 22 bears against the periphery of the disc 16 and when it engages with the notch on the disc operates a catch 31 which allows the main clutch 32 to be automatically disengaged, the clutch can also be operated through the catch by a hand lever 25 at any time during the working of the machine. The device operates as follows :-The work-bar 1 as shown is about to enter the hollow spindle of an automatic lathe and so as to prevent injury to the machine through feeding a length of stock too short for an article to be made the lathe is arranged to be automatically stopped after a predetermined length of stock has passed the detector 2. This is effected by setting the notch on the disc 16 a definite angular amount from the zero position of the wheel 5 determined by a spring- pressed detent 20. The pawl then rotates the toothed wheel one step for each complete revolution of the shaft 8 and after a predetermined number of steps the automatic stop is operated. The disc 16 can be reset by the handle 34 for a fresh set of operations on a new bar.
