Title: Permeable cellulosic bodies containing enzymes
IPC: C12N11/12
Filed: 1974-03-15
Abstract: To obtain cellulosic fibres containing enzymes, capable of displaying a catalytic activity in enzymatic reactions, a substituted cellulose derivative is dissolved in a water-insoluble solvent. An aqueous solution of the enzyme is then added to the solution, and the emulsion is subjected to spinning and coagulation conditions. Finally, the fibre obtained is treated with a reducing agent, in order to remove the substituent under operating conditions which do not damage the enzyme. The substituted cellulose derivative can, for example, be nitrocellulose. In this case, the reducing agent is a solution of ammonium sulphide. The said substituted cellulose derivative is dissolved in a water-insoluble solvent selected from normal-butyl acetate, dibutyl phthalate, methyl amyl ketone and ethyl amyl ketone.   The enzyme used is selected from uricase, invertase, lactase, acylase, transaminase, glucose oxidase, catalase, papain, tryptophan synthetase and penicillin amidase. This gives cellulose fibres having a permeability very much higher than that of the same fibres based on substituted cellulose.

Title: A method and apparatus for de-infesting worm-ridden timber
IPC: B27K3/10
Filed: 1956-04-18
Abstract: 847,649. De-infesting timber. WATT, C. April 17, 1957 [April 18, 1956], No. 11835/56. Class 140. Worm-ridden timber is de-infested by injecting into it in succession compressed air, a spray of liquid insecticide and liquid insecticide alone under pressure. Apparatus for carrying out the method comprises a pump B supplying compressed air to a vessel C containing liquid insecticide, the vessel having tubes 47, 48 opening above and below the liquid respectively and communicating with a control valve A which itself is connected to a spray nozzle S containing a hand-operated valve. The control valve A is spring-biased to communicate initially with the tube 47 but the passage of compressed air therethrough when the nozzle is opened produces a pressure drop at the valve face and causes the valve to switch over whereby first both tubes 47 and 48 are opened and a mixture of air and liquid supplied and finally tube 47 is closed and liquid alone supplied through tube 48. The pump B may be mounted on a trolley carrying an air reservoir and may be electrically driven, air being delivered from the reservoir through a non-return valve and an adjustable pressure-control valve which switches off the pump and opens a bleed valve in the reservoir when a predetermined pressure is attained. The nozzle S may be that described in Specification 850,357. Specification 847,651 also is referred to.

Electrode furnaces; resistance furnaces.-A furnace having a resistance c of material non-conductive when cold, such as sand, clay, chalk, furnace waste, or mixtures of such substances, is started without external heating, by the use of an ionizing- substance. A mixture of caustic alkali and sand may for instance be made into a cartridge d and placed on the resistance c between the electrodes e, e<1>, or may be sprinkled in a gully in the resistance. On wetting the alkali, it conducts and heats the resistance to conductivity. An increase of temperature may be produced during working by adding a reacting material such as lime, which may either be spread evenly over the resistance or stirred in at points where higher temperatures are required. The furnace shown has a non-conducting lining b, a hood f, and a flue f<1>. It may be employed for melting, refining, and distilling metals, melting and boiling lime or zirconia, &c.

Title: Surge control system for the compressor section of a turbine type power plant
IPC: F04D27/02
Filed: 1974-03-19
Abstract: 1457311 Axial-flow compressors UNITED AIRCRAFT CORP 19 March 1974 [2 May 1973] 12158/74 Heading F1C The invention relates to a surge control system for opening a bleed valve of the compressor section of a gas turbine power-plant so as to prevent or eliminate surge therein. The system comprises a sensing device 10 and a hydraulic control 12 which is connected to actuator 50 which controls opening and closing of a compressor bleed valve 51. The sensing device comprises a diaphragm 20 which separates two chambers 26, 24 which are both connected to compressor discharge pressure the upper chamber 26 through an unrestricted passage 28, and the lower chamber 24 through a passage 30 having a flow restrictor 32. Upon occurrence of surge the diaphragm 20 is thus moved upwardly due to the sudden drop in pressure in the chamber 26, and the flapper 34 which is pivotally mounted to the casing at 36 and to the diaphragm at 38 moves clockwise to open the orifice 40 whereupon pressure fluid in the space 84 at the lefthand end of the the servo valve 58 is released through the unrestricted passage 92, the check-valve 94 opening against the loading of its spring. Thus the servopiston 58 is moved to the left by the pressure of fluid acting on the face 74 (which is half the area of the opposite end-face 72), and high-pressure fluid in line 68 passes through annulus 66 to the line 64 and actuator 50 which moves to open the bleed valve 51. When the surge condition has passed, the diaphragm moves downwardly causing the flapper to pivot about point 36 to close the orifice 40. Servofluid in line 42 now passes through the passage 82 but at a relatively slow rate due to the restriction 90, to the chamber 84. Thus the servopiston 58 moves to the right and the line 64 is connected through annulus 62 to the drain line 60; the actuator 50 thereupon returns and the bleed valve 51 moves to the closed position. The control unit 52 is arranged to that upon movement due to sensing of a surge condition the servovalve 58 moves beyond the null position whereby the bleed valve remains open for a period of time after the pressure drop sensed by the device 10 returns to its normal value.
