Title: Vacuum distillation
IPC: B01D3/12
Filed: 1938-11-14
Abstract: 521,227. High vacuum distillation. EASTMAN KODAK CO. Nov. 14, 1938. No. 33030. Convention date, Nov. 13, 1937. [Class 32] In a process of high vacuum unobstructed path distillation, the material to be distilled is subjected to a temperature substantially higher than that necessary to ensure high vacuum short path, and particularly molecular, distillation of such material, a distance of at least five times the mean free path of the molecules separating distilling and condensing surfaces, and the pressure of the distillate vapour stream generated, whilst being less than 1 mm. Hg., always exceeding the pressure of residual gas. Specified materials which may be treated are fatty acids, sterols, hormones, vitamins, and animal. vegetable and mineral oils, e.g., pollack liver oil, soya bean oil and coconut oil. Stills of the type described in Specifications 482,882 and 482,883 may be employed, and fractionation may be obtained by operating in a plurality of successive stills. In an example, pollack liver oil is distilled in a molecular still of conventional design. comprising 5 columns in which the operating conditions are as follows:- The first and second columns are thus operated under non-molecular conditions, the pressure of residual gas being greater than that of the distilling vapour. The third column is operated under true molecular conditions, and here vitamins A and D are recovered. In columns 4 and 5, rapid saturation distillation of the main bulk of fatty glycerides takes place, according to the process of the present invention. Further examples are given, of the separation of colouring matters, essential oils and sterols from soya bean oil in a centrifugal type still, and of the distillation of rancid coconut oil in five stages.

Title: Improvements in and relating to the governing of internal combustion engines
IPC: F02M21/00
Filed: 1929-11-01
Abstract: 342,660. Centrifugal -governors. JUNKERS, H., 21, Kaiserplatz, Dessau, Anhalt, Germany. Nov. 1, 1929, No. 33303. Convention date, Nov. 9, 1928. [Class 57.] In a governor for internal-combustion engines, particularly for road vehicles, an auxiliary device is arranged which when changing to higher speeds reduces the deflection of the member adjusted by the governor. The governor muff 3 is connected by a bell crank 4 and rod 5 to the rack and pinion 6, 7 operating the throttle or other means of controlling the fuel supply. The loading spring 2 on the governor is adjusted by moving the pedal 11 which is connected by lever 12 to the bell crank 10. A stop 14 is connected by the lever 13 to the bell crank 10 and coacts with the stop 15 on the rod 5. The governor is set to allow the maximum permissible load to be put on the engine at low speeds. To increase the speed the spring 2 is compressed and at higher speeds as the stop 14 approaches the stop 15 the maximum amount of fuel that can be supplied to the engine is progressively reduced, thus reducing the maximum load that can be put on the engine and prevent any overstrain. In a modification the link 13 is arranged on an extended arm of the bell crank 10 and the stop limits the travel of the governor muff.

Title: Dc to dc converters
IPC: H02H7/18
Filed: 1974-07-29
Abstract: 1455498 Automatic voltage control HONEYWELL Inc 29 July 1974 [30 July 1973] 33433/74 Heading G3R [Also in Division H2]  A D.C.-D.C. converter comprises an oscillator supplied from a first D.C. source 2 and including a transformer 19, the output of the transformer being rectified at 27 to provide a second D.C. output and monitoring means including a programmable unijunction transistor (PUT) (i.e. an anode gate thyristor) 36 arranged to compare one of the voltages of the converter with a reference voltage 41 and to stop the oscillator when the voltage passes a predetermined limit. In the electronic flash apparatus described, the oscillator 1 comprises a transistor 24 having feedback via transformer 19. During each cycle, the current in transistor 24 builds up until the core of transformer 19 saturates when the base current becomes reduced, cumulatively turning off transistor 24. When capacitor 32 has recharged sufficiently to turn on transistor 24 again, a further pulse is produced. This is arranged to occur before the flux in transformer 19 has fallen to zero so that the current in winding 20 jumps to a substantial value immediately. Each pulse in the secondary winding 21 is rectified at 27 and charges capacitor 3, which may be discharged via the flash tube 9 by operation of push button 12. When the capacitor 3 charges to a voltage above that predetermined by reference Zener diode 41 and potentiometer 37, the PUT 36 breaks down, turning on transistors 47 and 49, lighting lamp 50, and inhibiting operation of the oscillator 1. This action continues until the voltage across capacitor 3 falls sufficiently to allow the PUT 36 to turn off when the oscillator recommences. Alternatively, the PUT 36 may monitor the voltage across winding 22 of the transformer 19. Monitoring battery voltage. If the battery voltage falls below a limit set by Zener diode 55, PUT 52 becomes triggered, turning on transistors 58 and 49 and inhibiting operation of the oscillator 1. A lamp 59 indicates this occurrence.

Title: Differential overprinting of rayon flocked cotton fabrics
IPC: D06Q1/06
Filed: 1962-08-31
Abstract: Differential colour effects in cotton-containing fabrics are produced by pretreating the fabric with a material which modifies its ability to be dyed by a reactive dyestuff, e.g. a cellulose reactant anti-crease agent (or alternatively a reducing agent or an acid salt), flock printing a design with rayon flock fibres and overprinting at least part of the flock-printed design and at least part of the unprinted fabric with a cellulose reactant dyestuff.  The unflocked base fabric may be predyed with a black dye (omitting the anti-crease treatment) to form a colour resist thereon, or with a non-black dye followed by the anti-crease treatment to obtain a colour resist.  As an optional feature, the anti-crease treated fabric may be calendered prior to flock printing.  In a specific embodiment, bleached cotton fabric is treated with an aqueous composition containing dimethylol ethyleneurea, dicyandiamide, glycerine, polyoxyethylene fatty/resin ester, ethanolamine hydrochloride and wax-modified polyethylene emulsion, calendered, flock printed with viscose tow using a polyurethane base adhesive and overprinted with dyes known under the Trade Marks "Cibacron," "Drimarine," "Procion" and "Remazol," with the addition to the printing composition of NaHCO3, Na2CO3, NaOH, urea, sodium, m-nitrobenzenesulphonate and sodium alginate, followed by ageing, washing and dyeing.

[Classes 39 (i) and 40 (v).] Failure of the supply of cooling medium to a thermionic valve causes the movement of a member situated in the supply pipe, themovement being transmitted magnetically to an external member to indicate the failure or to cut off the power supply. Water is supplied to a valve through a pipe 4 and a glass byepass 6, in which is situated a hollow iron float 18. Corrosion of the float is prevented by a coating of varnish or of the material known under the Registered Trade Mark " Bakelite." The tube 6 is partially enclosed by the cheeks 9 of a permanent magnet, which, when the float 18 drops, moves to operate a switch 14, such as a mercury switch, through a lever 10. The lever 10 may be of insulating material and may be provided with an adjustable balance weight. Adjustable valves may be provided in the pipes. When a single supply pipe is used, the float is hollow to prevent undue resistance to the flow of water. The float may consist of a glass tube containing iron filings.
