Patent GB-1582460-A (GB)
Title: Device for extracting air from packages such as freezer bags
IPC: B65B31/04
Filed: 1977-04-12
Abstract: The apparatus extracts the air from the bag by means of a water-jet pump (2-16, 20-23) which is connected to a water cock. The extraction of air is to be possible both before and after the closing of the bag. Should the air be extracted before the bag is closed, there is provided a two-part exchangeable connection member which is connected to the water-jet pump by means of a hose (19) and into which the open end of the filled bag is clamped. If the removal of air from the bag takes place after the latter has been closed, instead of the connection member a suction nozzle is inserted at the hose end and is pricked into the bag, from which it then sucks off the air. The pricking orifice is closed by means of a piece of self-adhesive foil. If there is no commercially available foil-welding appliance for closing the bag, the gathered-together bag end can be pressed sealingly together by the force of a screw by means of a special closing clamp. The apparatus is primarily provided for use in households and in small businesses. <IMAGE>

Title: The production of carbon filaments
Inventor: RENDELL MICHAEL

Filed: 1967-04-04
Abstract: 1,221,423. Carbon filaments. COURTAULDS Ltd. 18 June, 1968 [4 April, 1967], No. 15383/67. Heading C1A. Carbon filaments are produced by heating organic filaments under sufficient tension to prevent or restrain shrinkage to a temperature within the range from 200‹ to 300‹ C. for 30 minutes to 4 hours in air, air enriched with oxygen, other oxidizing gas, or an inert atmosphere, heating in an inert atmosphere to a temperature at which the filaments conduct electricity, and heating to a temperature of at least 1000‹ C. for 30 minutes to 4 hours by passing an electric current through the filaments. The filaments produced may be graphitized by further heating at a temperature of not less than 2000‹ C. in an inert atmosphere by passing an electric current down the filaments. Suitable organic filaments are filaments of cellulosic, polyamide, polyester, polyacrylic or modacrylic material, and a suitable inert atmosphere for the first heating stage is nitrogen. The carbon filaments become sufficiently conducting to be heated by the passage of an electric current at about 500‹ C. Electrical power can be fed into the filaments by passing them over carbon rollers. A series of rollers may be employed in which the power input to each roller is controlled to ensure the correct temperature gradient along the filaments. Reference has been directed by the Comptroller to Specification 1,034,542.

Filed: 1958-05-14
Abstract: 888,955. Discharge tubes. STANDARD TELEPHONES & CABLES Ltd. May 14, 1958, No. 15408/58. Class 39(1) An electric discharge device comprises two ceramic insulators having surfaces placed closely adjacent each other, an anode formed on and extending over part of one of said surfaces, a cathode formed on and extending over part of the other of the surfaces and a control electrode on and extending over one of the surfaces and spaced from the other electrode on the same surface. In one form an insulator 1, Fig. 1, has a strip 4 defining the cathode which is separated by grooves 2, 3 from areas 5 which form a control electrode. The second insulator 15, Fig. 3, has projections which carry metallic strips 17 comprising the anode. In the arrangement of Fig. 6 two insulators 20, 25 are placed in close juxtaposition to one another. Insulator 20 carries a cathode comprising molybdenum, nickel and emissive material strips 23, 24, 31 respectively which are preferably separated from the control electrode by grooves, the control electrode comprising a molybdenum coating which may in turn be coated with a layer 32 of secondary emissive material to increase the mutual conductance of the device. A cathode heater 22 is provided in grooves 21, or the strip 23 may be used as the heater, or alternatively the cathode may be coated with a self-sustained emissive material. The second insulator, 25 which carries a metal coating 29 forming the anode, also has projections 26 carrying layers of molybdenum 27 and gold 28 forming a second control electrode. The two insulators may form part of the envelope, or the arrangement may be placed in a separate glass envelope. The insulators may be of forsterite. The molybdenum strips may be deposited by a printing process and the nickel and gold layers by electroplating, each deposition being followed by baking in hydrogen to improve adhesion and leads for the electrode may be sealed through the insulators at this stage. The strip defining the cathode may be coated with mixed carbonates of barium, calcium and strontium by electrophoresis, this layer later being heated to reduce the carbonates to oxides by applying a potential difference across the ends of the cathode strip. The cathode and control electrode on insulator 1 need not be in the same plane and may be domed or otherwise shaped to produce the required field configuration. In a further embodiment the insulators comprise two cylinders 38, 39, Fig. 8, not necessarily coaxial, on which cathode 42, control electrode 41 and anode 43 are formed. The ends may be hermetically sealed by ceramic discs. A gas filling may be present.

These movements are derived from a hand wheel z, Fig. 2, driving through worm gearing x a transverse shaft r having eccentrics controlling the vertical movement by blocks t on the bar k and spring plungers u in the brackets. The horizontal movement is simultaneously derived from a cam v, Fig. 4, on the shaft r rotating between follower blocks on the bar k. The bars g are adjustable axially by hand operated rack and pinion gearing.

Title: Alkyl 3-alkoxypropionates
Inventor: FOX WILLIAM JOSEPH
IPC: C07C69/24
Filed: 1957-05-16
Abstract: Alkyl 3-alkoxy propionates are prepared by contacting a symmetrical dialkoxy methane with ketene under substantially anhydrous conditions at a temperature in the range of from 10 DEG  to 60 DEG  C. and in the presence, as catalyst, of not more than 5% by weight of BF3 based on the dialkoxy methane.  Generally a molar ratio of ketene : dialkoxy methane of from 0.5 : 1 to 0.9 : 1 is used.  The catalyst may be present in the form of its diethyl ether complex.  Suitably, the ketene is bubbled into the dialkoxy methane, if desired under elevated pressure.  The reacted mixture is then neutralized and fractionally distilled to recover the ester.  Examples describe the conversion of dimethoxy methane, diethoxy methane and di-n-butoxy methane into methyl methoxy, ethyl ethoxy and butyl butoxy propionates.  Di-isopropoxy- and diisobutoxy methanes are also mentioned.  Comparative experiments show the reduction in yield obtained by operating at -5 DEG  to 0 DEG  C.  The first Provisional Specification describes the reaction of ketene with dialkoxy methanes under substantially anhydrous conditions in the presence of at least 5% by weight of a BF3/diethyl ether complex based on the dialkoxy methane at temperatures of, for example, - 5 DEG  to 40 DEG  C.  The second Provisional Specification specifies for the same reaction the use of not more than 5% by weight of the BF3-ether complex based on the dialkoxy methane and of temperatures above about 300 DEG  C. U.S.A. Specification 2,436,286 is referred to.
