Title: Improvements in and relating to the separation of acetone and butanol from fermentation liquors containing the same
IPC: C12P7/28
Filed: 1944-07-11
Abstract: Acetone and butyl alcohol are obtained from the liquids in which they have been produced in dilute solution by a fermentation process, for example by the growth of clostridium butylobutyricum (Weizmann), clostridium butylobutyricum or clostridium saccharo aceto-butylicum, on carbohydrate mashes, by first separating the liquids from the solid residues, and then passing these liquids through a mass of activated charcoal during such time as the output liquid is free from acetone and butyl alcohol, and rejecting this liquid, continuing the passage of the fermentation liquids through the mass of activated charcoal until substantially the whole of the butyl alcohol is adsorbed while substantially the whole of the acetone content remains in solution.  The dilute solution of acetone in water is then passed through another charcoal mass till substantially all the acetone is adsorbed by the charcoal.  The solvents are then separately recovered from their separate masses of charcoal by circulating steam or an inert gas such as air at atmospheric pressure, or preferably by external heating of the charcoal mass together with the application of a moderate vacuum.  The charcoal is then ready for re-use or it may be further activated by steam if desired. Examples are given which illustrate the effect of different rates of feed and different concentrations of feed solution on the efficiency of the method.

Title: Improvements in or relating to method of manufacturing a roll type capacitor and theresulting product
IPC: H01G13/02
Filed: 1948-02-27
Abstract: 679,907. Electric condensers. DEPARTMENT OF COMMERCE, DIRECTOR OF THE OFFICE OF TECHNICAL SERVICES OF. Feb. 27, 1948 [July 28, 1944], No. 12296/51. Divided out of 679,816. Class 37. A condenser is made by coating two metal foils with liquid or paste vitreous enamel, leaving a strip along. one edge clear of coating, partially drying the strips, winding them into a roll so that the uncoated portions extend outwardly from opposite ends of the roll, firing the roll into a monolithic structure and connecting electrical leads to the two ends. Metal foils 173, 175, Fig. 1, unwind from spools 189 and pass through acid cleaning baths 191, rinsing baths (not shown) and drying oven 199; they then pass through masks 209 and are sprayed with a paste of vitreous enamel so that a wide strip 283 is left on one edge of one ribbon and a wide strip 285 is left on the opposite edge of the other ribbon; they then pass through a.drying oven 215, and are wound at 217 into a roll-type condenser, the metallic edges 283, 285 protruding at each end; knives 223 cut the ribbons as necessary to terminate the rolling. Each roll falls into a holder 231 and is carried into a furnace 227, Figs. 1 and 2, for fusing into a monolithic structure; on emerging from the furnace, members 235 (only one is shown) are automatically applied to each end of the rolls 181 to deposit soldering flux thereon, and members 243 are similarly operated to deposit solder on the ends; leads held in a shoot 251 fall into a holder 249 and are automatically brought into contact with the ends of the rolls, while gas flames 263 play to fuse the leads to the protruding metal edges. The condenser is then transferred by push-rod 273 into an enamel casing 185 which is then carried to rollers 275, 276 where it is rotated while gas flames 279 play on the ends of the casing to fuse them about the protruding leads; the condensers then pass to the annealing oven 281. The vitreous enamel may be a silicate flint glass, it should have a lower melting point than the metal foil and should have the same coefficient of expansion as the metal foil. The spraying at 177, Fig. 1, may be modified by replacing the masks 203 by vertical plates 289, Fig. 6. Alternatively, the ribbon may be dipped into a vat of vitreous enamel, Fig. 7 (not shown). Again, the whole surface of the ribbons may be coated, the appropriate edges being subsequently wiped clean. In a further modification, a layer of enamel is first produced by spraying, then a metallic foil laid thereon, e.g. by spraying, and finally another layer of enamel produced by spraying, the composite strip so formed being treated as in Figs. 1 and 2, i.e. drying in oven 215 &c. Specification 679,816 is referred to.

Filed: 1974-03-22
Abstract: 1455801 Thermo-electric radiation detectors INTERNATIONAL BUSINESS MACHINES CORP 22 March 1974 [4 May 1973] 12987/74 Heading H1K A radiation detector comprises a film 1 of an electrically conductive material exhibiting induced anisotropy, and terminals 3, 4 on one surface of the film 1 to detect a thermo-electric voltage generated therebetween when the film 1 is irradiated 5 in such a manner that a temperature gradient is produced across the thickness of the film 1. The film 1 may be made of a transition metal such as Ti, V, Cr, Co, Ni, Fe, Ta, W, U, Os, Ir, Pt or Mo and may be supported by an electrically insulating, thermally conducting substrate 2 over its entire area as shown, or only peripherally. The thermo-electric voltage varies in magnitude and polarity according to the location of the terminals 3, 4 relative to the axis of the induced anisotropy, and the direction of incidence of the radiation 5 also affects the output polarity. The anisotropy may be temporarily induced by the application of a magnetic field or may be permanent, associated with mechanical stress induced in the film 1 as by vacuum deposition at a low substrate temperature (e.g. room temperature) or by growth of the film 1 on a substrate of very different thermal coefficient of expansion. An example of the last-mentioned case is Mo grown on vitreous quartz and thermally cycled to 600 C. In this case the generated thermoelectric voltage increases with increasing operating temperature, due to increasing stress. Radiation 5 may be a laser or electron beam, for for infra-red radiation an anti-reflecting coating of Ge or LiF, or an absorbing coating, may be applied to the film 1.

Title: Pneumatic Device, particularly for use in an Artificial Heart Machine

IPC: A61M60/851
Filed: 1967-03-20
Abstract: 1,184,942. Cardiac massage apparatus. BLEASE MEDICAL EQUIPMENT Ltd. 20 March, 1967, No. 13000/67. Heading A5R. In a device for producing cyclically varying gas pressures for cardiac massage, the duration of the high pressure phase is controlled by the rate of exhaust of a first chamber C1 through a first flow regulating valve FR2 and the duration of the low pressure phase is controlled by the rate of rise in pressure in the chamber as it is fed with gas through a second flow regulating valve FR1. Gas at a pressure of 150-200 mm. mercury above atmospheric pressure is supplied through a line SL and the cyclically varying pressure is produced at the outlet O for application to the heart. During the high pressure phase gas flow the line SL passes via a chamber C2, a valve V1 and a conduit T3 to the outlet O and to a chamber C5 which is maintained at the same pressure as the outlet O. A diaphragm D1 then holds the valve V3 against a seat S3 to close a chamber C4 and away from a seat S4 to provide for escape of gas from the chamber C1 to atmosphere through the regulating valve FR2. Due to falling pressure in the chamber C1, a diaphragm D2 closes the valve V1 after an interval determined by the valve FR2 to terminate the high pressure phase, Also a valve V2 is opened by the diaphragm D2 to vent gas in the conduit T3 and the chamber C5 through an outlet E1. The pressure in a chamber C4 communicating with the supply line SL overrides the pressure in the chamber C5 to move valve V3 from its seat S3 to its seat S4 and thus the chamber C1 is connected to the supply line SL via flow regulating valve FR1 and the chamber C4. The pressure in the chamber C1 thus rises during the low pressure phase at a rate determined by the setting of the valve FR1 until it is sufficient to move the diaphragm D2 to open the valve V1 and thus re-establish the high pressure phase.
