Title: Preparation of coenzyme q-10
IPC: C12P7/66
Filed: 1959-09-25
Abstract: The hydroquinone corresponding to coenzyme Q-10 (see Group IV(b)) is used as antioxidant to prevent the devolopment of rancidity in fats and oils.ALSO:A process for producing coenzyme Q-10 comprises cultivation of a bacterial strain selected from the genera Pseudomonas and Proteus in an aqueous medium containing assimilable sources of carbohydrates, nitrogen and essential inorganic salts until a demonstrable amount of the quinone, coenzyme Q-10 has been formed and isolating coenzyme Q-10 by a method which comprises treating the resulting broth by extraction with an organic solvent phase either after or without previous hydrolytic treatment. Carbohydrate sources specified include sucrose or brown sugar, dextrose, maltose, lactose, beet molasses, rye, ribose, dried whey and cottonseed meal, sources of assimilable nitrogen specified include pure or degraded proteins, amino acids, corn-step liquor yeast autolysate, soybean meal, urea and inorganic ammonium compounds.  The addition of sources of potassium, phosphorus and traces of zinc, inon, manganese and magnesium which may be in the forms of salts such as nitrates, chlorides or sulphates is desirable. Hydrolysis may be carried out with acid or alkaline agents e.g. aqueous ethanolic potassium hydroxide or sodium hydroxide and in the presence of antioxidants e.g. pyrogallol or reducing agents. Solvents specified include light petroleum fractions, hexane, chloroform, acetone and alcohol.  Crude preparations of the coenzyme may be purified by chromotography or countercurrent extraction. Methods for the determination of the coenzyme are indicated. Bacterial strains specified for use in the process include Proteus vulgaris and Pseudomonas denitrifians, specified for use in the process include Proteus azotocolligans, diminuta, woodsii, tomato, and vitiswoodrowii. Mutant strains commonly used in the art produced from species of the genus Proteus and the genus Pseudomonas ultra violet or X-ray irradiation and other physical and chemical treatments may be employed in the process.

Abstract: 938,466. Programmed control systems. E. 1. DU PONT DE NEMOURS & CO. Aug 27,.1962, No. 32894/62. Class 38 (6). In a binary-coded programmed control system a programme input, comprising an ordered sequence of process control steps, is fed to a programme storage device 10 which supplies programme guidance, unique to each step, progressively through an instruction decoding section 11, to a conditional logic section 12, command logic section 14 and process step sequence control section 15. The section 15, upon receipt of an " advance " signal from the conditional logic section 12, delivers an output signal to a step programme address selection section 17 which effects the choice of the programme unique to the next process step. The command logic section 14 controls process steps through two distinct outputs D1-Dn, leading to field actuated devices, such as valves and pumps, and S1-Sn, leading to auxiliary devices, such as timers exercising a duration of operation control on agencies affecting process control directly. The conditional logic section 12 monitors the process step by signals which are received at field inputs, F1-Fn obtained from electric limit switches monitoring the degree or fact of the opening of valves or level control devices, and instrument inputs I1-In, which include signals from transducers responsive to pressure, temperature or viscosity.

Filed: 1922-12-02
Abstract: 208,361. Smith, J. Dec. 2, 1922. Unpacking.-A cartridge device for charging grease guns comprises a container or cylinder A fitted with a piston B and a piston-rod C which are capable of being interlocked for discharging the grease from the container into a grease gun barrel and also of being disengaged for transport, the piston-rod being then inserted into the grease as shown. The container has an end cap a which is removed before the container is applied to the opened end of the grease gun barrel, and the rod C is secured to another end cap c, which is also removed and the rod C drawn out until its cranked end c<1> abuts against the piston B, when a slight turning movement of the rod causes the end c<1> to be engaged between the piston and a rod b which extends across it. When the cap c is forced towards the container, the grease is expelled by the piston into the grease gun. In a modification, the cranked end c<1> engages lips stamped and pressed from the material of the piston, the holes so formed being closed by a plate pressed into or otherwise attached to the piston; or a spring fastening device on the rod may automatically interlock with the piston.

Title: Method of and means for hardening metal parts by means of the electric current
IPC: C21D1/40
Filed: 1936-12-02
Abstract: 476,910. Cementation. MOURAVIEFF, P., and MESTER, B. Dec. 2, 1936, No. 33060. [Class 72] [Also in Groups XXXVI and XI] Metal articles are hardened and cemented by treatment as electrodes in a saturated solution of a cyanide or other salt or of an organic substance with a voltage of 150- 200 and current density of 1 amp. per sq. cm. of the surface treated. The opposing electrode is preferably of large area. Under these conditions a sleeve of gas and vapour is produced over the part treated across which a spark or arc discharge takes place. Local heating is caused in part by combustion of the gases produced. The electrolyte is heated slightly by the discharge ; it may be cooled if necessary by circulation. Alternating, preferably high frequency, or direct current may be employed, the article in the latter case being connected as cathode. The article may be surrounded by an insulating screen having an aperture which may be moved to treat parts of the article successively. Parts of a knife 14 are treated successively by sliding the edge in a groove 12 in an insulating block having a recess containing the anode 15. For carbon cementation the electrolyte may be a solution of sugar or of an organic acid or alcohol the conductivity of which is increased by addition of cyanides ; for nitration it may consist of ammonia together with sodium cyanide or potassium ferrocyanide. Silicon may be introduced by use of a suitable electrolyte. An article may be treated by drawing it in the bath over an electrode of agglomerated coal and silicon with which it forms a bad or intermittent contact.

The embodiments described are identical to those described with reference to Figs. 11-14 and 15-24 of Specification 1,153,495, and to those described in Specification 1,153,496, but the claims are directed to a transistor in which a diffused emitter region is surrounded by a diffused base region comprising a high resistivity part underlying a central portion of the emitter region, and an adjoining relatively low resistivity part underlying an adjoining outer portion of the emitter region and extending to the transistor surface. Ohmic contacts to the emitter region and the lower resistivity part of the base region are made through openings in an insulating layer on the transistor surface. It is stated that the emitter-base configuration accentuates the base-current " crowding " effect, with a consequent improvement in the highfrequency performance of the transistor. A P + grid may be diffused into the transistor surface in the base region in order to facilitate the making of ohmic contact thereto in a silicon NPN transistor.
