Title: Fermentation of sugars
IPC: C12P7/28
Filed: 1929-07-05
Abstract: 315,002. Burgess Laboratories, Inc., C. r., (Assignees of Viljoen, J. A.). July 6, 1928, [Convention date]. Acetone is prepared by the fermentation with Clostridium acetobutylicum of a solution containing about 5 per cent or more of sugars and deficient in buffer nitrogen. A sterile starter mash is prepared containing insufficient sugars to cause plasmolysis of said bacilli and containing sufficient proteolyzable protein, which may be soya-bean meal or in the form of keratin, to prevent the formation of a lethal concentration of organic acids; the mash is inoculated with the bacilli and allowed to ferment until the bacilli are at their highest concentration. A second sterile mash containing sufficient sugars to cause plasmolysis of said bacilli if present in small numbers, is prepared and added in equal volume to the starter mash, the combined mashes being allowed to ferment to produce a high yield of alcohols and acetone. 'The second sterile mash may be a molasses solution, and the sugars in the starter mash may be added as molasses. Sufficient proteolyzed protein should be present in the combined mashes to neutralize organic acids formed. In an example, 4 per cent Cuban molasses containing oil-free soya-bean meal are inoculated with 3 per cent corn-meal culture, and after allowing the starter to ferment, Cuban molasses are added gradually.

Title: Improvements in shutters for kinematograph apparatus
IPC: G03B9/10
Filed: 1923-08-16
Abstract: 209,029. Etablissements Continsouza Soc. Anon. Dec. 26, 1922, [Convention date]. Void [Published under Sect. 91 of the Act]. Kinematograph apparatus.-A shutter comprises two wings 1, 8, the wing 1 being secured to the shaft 4, and the wing 8 being secured to a collar 9 which is loose on the shaft 4 but attached thereto by a spring 11. A blade 10 is provided on the wing 8 so that the resistance of the air opposes the action of the spring 11 and causes relative movement of the wings when the shaft begins to rotate. The aperture between the wings increases with the speed of the shaft until at the maximum speed one wing lies behind the other and further relative movement is prevented by a stop 12. The spring 11 and the blade 10 may be adjustable, one or both the wings may rotate in a medium other than air, e.g. water, and the blade 10 may be replaced bv a number of blades forming a fan which in conjunction with a casing round the shutter and a suitable channel causes cool air to be discharged on to the film in the gate.

Title: Improvements in devices for controlling a movable machine part
IPC: G05D3/12
Filed: 1932-07-25
Abstract: 386,576. Control of several motors. ZEISS, C., [Firm of], Carl-Zeiss-Strasse, Jena, Germany.-(Assignees of Karabetz, H. von; 31, Am Kiesh³gel, Jena, Germany.) July 25, 1932, No. 20886. Convention date, July 25, 1931. [Class 38 (iii).] Following movements of control member.-A wheel 3 driving a machine is caused to follow the movements of a member 2 and is driven by a continuously running motor 15 through differential gears 24, 25, 40. The motor imparts equal rotations through worm-drives to shafts 20, 21, and if crown-wheels 26, 27 of the gears 24, 25 are held at rest by reason of auxiliary motors 7, 9, with which they are associated through worm drives, being also at rest, then equal rotations are imparted to shafts 34, 35. The casing of the gear 40 is subjected to the difference of these rotations, and hence it, and the wheel 3 driven thereby, remain at rest. If the member 2 is displaced; so as to contact with a sector 5 on the wheel 3, then the auxiliary motor 9 runs in such a direc. tion as to allow the wheel 27 to turn in the direction that it tends to turn, hence shaft 35 slows down and the casing of the gear 40 turns in such a direction that the wheel 3 follows the movement of the member 2. In one modification the two auxiliary motors 7, 9 are replaced by a single reversible motor which drives one or other associated worm wheels through a one-way drive-device according to the direction of rotation of this single motor as controlled by the relative position of the member 2 and wheel 3. In another modification, the wheels 22, 23, Fig. 3, are held stationary by a brake-lever 50. The member 2, in this case, co-operates with a cam-face on the wheel 3 so that relative movement between the member 2 and wheel 3 causes movement of the lever 50 about its pivot 51 and so allows rotation of one of the wheels 22 or 23, the shafts 34 or 35 being brought to rest by a light continuously acting brake 58 or 59. The brakes on the wheels 22, 23 may be actuated electromagnetically instead of mechanically, also they may be replaced by pawls co-operating with ratchet wheels.

Title: Improvements in or relating to the manufacture of synthetic filaments, fibres or yarn
Inventor: HOOKWAY DENNIS CAMPBELL
IPC: D02J1/22
Filed: 1954-07-17
Abstract: Artificial filaments and like products containing internal cavities are made by continuously drawing in a solid state a running or travelling monofil yarn or bundle of filaments, previously melt-spun from a high molecular weight synthetic linear condensation polymer, under one or more of the following conditions: a high degree of crystallinity of the polymer, a low degree of orientation of the polymer, a low moisture content of the polymer, a high speed of drawing and a low temperature of drawing, so that an abrupt neck is formed in the filaments and cavitation occurs within the filaments, the position of the neck in the running filaments being stationary or only allowed to hunt up and down a restricted path.  The crystallinity of the polymer may be increased by annealing it, e.g. for 20 hours at 160 DEG  C. in an atmosphere of nitrogen.  The polymer may be a polyurea, a polyurethane, a polyamide, a polyester or a polytriazole, e.g. polyhexamethylene urea, polydecamethylene urea, polybutylene glycol hexamethylene dicarbamate, polyhexamethylene sebacamide or adipamide, polypentamethylene or polyoctamethylene adipamide, polydecamethylene or polypentamethylene sebacamide, polydecamethylene hydroquinone diacetamide, polycaprolactam, polytrimethylene or polyethylene terephthalate, and polyoctamethylene-4-amino-1 : 2 : 4-triazole.  The term polymers includes copolymers and interpolymers such as interpolyamides made by heating together 5-amino-caproic acid, hexamethylene diamine and adipic acid.  In the case of polyhexamethylene adipamide its birefringence should not exceed 0.012, its moisture content should not exceed 1.3 per cent, the drawing temperature should usually be below 60 DEG  C. and is preferably about 40 DEG  C. or lower, and the speed of drawing should be as high as practicable without rupture of the yarn.  The isotropic refractive index of the polymer may suitably be 1.5365.  The restriction of the path up and down which the neck, when not stationary, is allowed to hunt, may be effected automatically by making any substantial shift in the position of the neck operate a photo-electric cell which by electric means alters the draw ratio by varying the speed of the draw (or feed) rolls.  The position of the neck may also be controlled by maintaining a local warm zone, or by passing the filaments round a snubbing pin.  In an example, undrawn polyhexamethylene adipamide meltspun yarn containing 0.1 per cent of moisture and having a temperature of 22 DEG  C. is drawn at a rate of 20 feet per minute (referring to the undrawn yarn), the draw ratio being 4.1 The undrawn yarn has been in equilibrium with an atmosphere of 1 per cent relative humidity. Yarns produced by the process of the invention have improved lustre and covering power.

Title: Improvements in and relating to electric voltage control systems for interconnected power circuits
Filed: 1943-12-14
Abstract: 589,854. Automatic control systems for electric supply apparatus. BRITISH THOMSON-HOUSTON CO., Ltd. Dec. 14, 1943, No. 20914. Convention date, Dec. 14, 1942. [Class 38 (iv)] Voltages.-In a supply system wherein independently regulated apparatus are selectively interconnected, time controlled means permits automatic voltage regulators to equalize the voltage of an individual apparatus before connection to the system. The Figure shows three similar circuits 1, 1<1>, 1<11> each incorporating a tap changing power transformer 5 regulated by a reversible servo-motor 11 controlled by a voltage relay 10. The control circuit of each relay comprises a potential circuit energized by a potential transformer 8 and a current circuit energized by a main current transformer 9. In series with the winding 10 is a circulating current compensating transformer 13 and a line drop compensator 14,'the action of the latter being rendered independent of the number of circuits in operation by auxiliary current transformers 20 which act to maintain equal currents in all the compensators 14. Auxiliary current transformers 16 ensure the separation of circulating and load current components, their secondaries being connected in series through conductors 15, 17, The secondaries of the transformers 20 are connected in series through conductors 15, 21. Short-circuiting switches 24, 25 and disconnecting switches 26 are provided. An equalizing conductor 22 connects the junctions of the transformers 16, 20. To connect circuit 1 to the system, for example, switch 32 is closed which energizes relays 33, 34, the latter being time delayed to enable the servo-motor which has been energized by the closing of relay 33, to equalize the voltage of the incoming circuit with that of the circuit in operation. The invention may also be applied to systems employing three single phase transformers normally delta connected but operable in open delta by disconnecting one. The invention is applicable to auto-transformer and induction regulators and to dynamo-electric machines. Specifications 587,881 and 589,853 are referred to.

Title: Improvements in cellulose derivative textile materials, foils and films
Inventor: OLPIN HENRY CHARLES
IPC: C08L1/12
Filed: 1952-08-26
Abstract: Filamentary textile materials and films of cellulose organic acid esters and ethers are given a good resistance to the gas-fading of subsequent colourations thereon by incorporating in the spinning solution an addition polymer derived from an ethylenic monomer, said polymer containing carboxylic anhydride groups, carboxylic acid groups, or carboxylic acid groups in the form of salts of alkali metals, alkaline-earth metals, magnesium or organic bases and the quantity of the cellulose derivative in the filament or film being at least 93 per cent.  Specified polymers are copolymers of maleic anhydride, acrylic acid or methacrylic acid with a vinyl compound, e.g. styrene, vinyl acetate, vinyl chloride, acrylonitrile and vinyl-methyl-ether, and polymers containing carboxyl groups obtained by the partial or complete hydrolysis of the ester groups of polymerized acrylic or methacrylic esters or copolymers thereof with vinyl compounds. The carboxyl groups of the polymer in the finished filaments or films should be in the form of a salt and to effect this the filaments may be subsequently treated with soap or alkali.  The finished filaments may be stretched in hot water or steam as described in Specifications 438,584, 438,585, 438,586, 438,587, 438,655 and 438,656 and, if desired, may be thereafter completely saponified to obtain filaments of high tenacity.  The finished filaments may also be superficially saponified to obtain level dyeings with direct cotton dyes.
