IPC: H01P1/32
Filed: 1958-10-09
Abstract: 920,065. Electromagnets. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Oct. 9, 1959 [Oct. 9, 1958], No. 32295/58. Class 35. [Also in Group XL (b)] A circuit for controlling the magnetic field in a waveguide Faraday-effect rotator comprises means for compensating the temperaturedependent remanence of the magnetic (e.g. ferrite) element. In the circuit shown, resistances R 1 , R 2  have values such that, with switch 1 in the position shown, the current in field solenoid 2 is sufficient to rotate the plane of the transmitted wave by a desired amount. Remanence of the magnetic element produces a certain residual rotation of the wave after the field current has been switched off. In order to restore the wave plane to its original position, the current in the field solenoid 2 is reversed by actuating the switch 1. Resistance R 3  and thermistor 4 have values and characteristics such that the reverse field current is sufficient to destroy the remanence of the magnetic element at the ambient temperature.

Title: Process for the production of elementary sulphur
IPC: C01B17/04
Filed: 1971-07-12
Abstract: 1356164 Production of sulphur SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ NV 12 July 1971 [14 July 1970] 32537/71 Heading C1A Elementary sulphur is produced from hydrogen sulphide according to a Claus-type process having at least two successive Claus-stages wherein a process stream taken from the first stage is fed to a reactor wherein reducible sulphur compounds contained in the process stream are hydrogenated and a hydrogen sulphide-containing stream obtained and is then introduced to the second of the successive Claus stages. Preferably the process stream to be fed to the reactor consists of the effluent of the Claus stage of which effluent elementary sulphur has been removed by condensation to liquid sulphur and subsequent removal thereof, the sulphur-free process stream thereafter preferably being heated to the reaction temperature required for conversion to hydrogen sulphide in the reactor. Preferably the reactor effluent is sufficiently cooled to condense water vapour to liquid water which subsequently is separated as a liquid phase. Hydrogen sulphide dissolved in the liquid phase is then recovered and preferably passed to the next Claus stage. The reducible sulphur compounds are converted into hydrogen sulphide in a reducing atmosphere which may be obtained by introducing a gas mixture containing hydrogen and carbon monoxide, the gas mixture being obtained by partial combustion of hydrocarbons with air, air enriched with oxygen or oxygen. The catalyst used in the reactor may be any conversion catalyst that has distinct hydrogenation activity, preferably containing at least one metal or metal compound from Group VI and/or VIII of the Periodic System of Elements. The conversion is usually carried out at 100 to 1000‹ C. with a space velocity of from 1000 to 20,000 Nm<SP>3</SP> gas per m<SP>3</SP> of catalyst per hour.

Title: Improvements to windscreen cleaners on vehicles
IPC: B60S1/34
Filed: 1931-11-24
Abstract: 385,408. Windscreen cleaners. DUNNETT, D., 77, Clarendon Gardens, Wembley, Middlesex. Nov. 24, 1931. No. 32538. [Class 138 (i).] An arm 6 adapted to be oscillated by a motor 7 is connected through a rod 5 and a link 1 to the arm 3 of a windscreen cleaner 4. The link 1 is pivotally connected to a bracket carrying a fixed sprocket wheel 10 which is connected by a chain 9 to a sprocket 8, to which the arm 3 is attached. As the arm 6 oscillates, the cleaner traverses a path indicated by the area 14 shown in dotted lines. As the wiper approaches either end of its traverse, a roller 11 slidably mounted on the arm 3 engages a cam 13 whereby the cleaner is withdrawn temporarily from contact with the screen. Continued upward movement of the cleaner causes the roller to fall off the cam, bringing the cleaner again into contact with the screen. Contact is maintained during the reverse downward stroke of the cleaner, whereby any liquid which has accumulated by the action of the wiper blade during the upward stroke is removed. Other means are described for causing the cleaner to jump over the accumulated liquid near each end of its traverse. In a modification, the rod 5 instead of being connected to the link 1 is connected to a point on the arm 3. In a further modification shown in Fig. 3, the arm 3 is pivotally connected to the rod 5 and to links 1, 15, both of which are pivotally mounted on a fixed bracket. In a further modification shown in Fig. 4, the oscillating arm 6 is connected by links 5, 5<1> to the arm 3 and link 1, respectively.

Title: Improvements in or relating to condensation products and cellulose derivative compositions containing them
IPC: C08L1/12
Filed: 1935-11-25
Abstract: An oxidized vegetable oil, e.g. oxidized castor, soya bean, olive or teaseed oil, is condensed with an aldehyde, e.g. formaldehyde, paraldehyde, metaldehyde, acetaldehyde or crotonic aldehyde.  The oil, and aldehyde equal to about 3 times the amount theoretically required to give one aldehyde molecule for each 2 hydroxy radicals of the oil may be refluxed with a catalyst such as orthophosphoric acid. Thus, 100 parts by weight of oxidized castor oil and 30 parts of formaldehyde may be refluxed at 100--130 DEG  C. for 4--10 hrs.  The products may be incorporated in filaments, foils, films, sheets, and lacquers having a basis of organic derivatives of cellulose to increase flexibility and pliability, preferably while the derivatives are dissolved in a volatile, substantially water-free solvent.  The amount of condensation product is suitably 1--20 per cent of the weight of cellulose derivative.  Suitable solvents are mixtures of acetone with methylene ether of ethylene glycol, ethyl or methyl alcohol, ethylene dichloride, and mixtures of ethylene dichloride with ethyl or methyl alcohol.  Pigments, fillers, dyes or lakes, fire retardants, plasticizers, sizes or lubricants may also be present. A solution containing 1 part cellulose acetate, 4 parts solvent, and 0,2 parts condensation product may be extruded as in dry or wet spinning to form filaments or cast on a film forming wheel. Thermoplastic compositions containing the condensation products and cellulose derivatives may be pressed into a block or rod which is then cut into sheets.  The condensation products may be incorporated in formed films or filaments by coating the latter in presence of a swelling agent, or they may be mixed with untreated or oxidized oil to form a lubricant dressing.

Abstract: 1,069,287. Making thermoplastic bags. H. MEMBRINO. Aug. 13, 1964 [Aug. 16, 1963], No. 33031/64. Heading B5D. [Also in Division B8] A machine for making bags from a roll of thermoplastic strip has a sensing element' controlling movement of the strip, one or more rotatably driven heat-sealing and cutting elements having one or more thermally insulated interruptions to form spaced interrupted lines of seal and severence in the strip, and means for packaging the bags after conveying them from the element. Thermoplastic strip (130) in the form of a flat tube or sheet folded longitudinally is fed, via rollers (144, 134) and a speed control (not shown) operated by a photo-electric device (146), between an impression roller (58) and a sealing head (56) which comprises a series of discs (162) mounted on a shaft (38) which have two heater bars (164) heated by resistance wires (166) extending transversely across the peripheries of the discs. A set of tapes 148 pass round the impression roller (58) to prevent the strip wrapping itself around the roller (58) and these tapes cooperate with similar tapes (152) extending around the discs (162) and externally of the heater bars (164) and wires (166) so that the heat seals and severs made in the thermoplastic strip as it passes by the rotating sealing head (56) are formed with interruptions corresponding to the tapes (152). A static eliminator is indicated at (196). The connected bags formed from the partly severed strip are passed on to an endless conveyer (198), past a knife (232) which slits open the strip if this is in the form of a tube to a conventional filling device (230) incorporating a tube (238) emitting compressed air to open the bags to facilitate filling. A sponge rubber roller (250) expels trapped air and a heat-sealer (254) closes the bag mouths. A roller (268) guides the bags between oscillating rollers (276) to stack the bags concertinawise; additionally, a series of sprocket holes may be provided in the bags for the strip to be fed for stacking in a manner similar to a film in a camera. The conveyer (198) and its associated parts may be pivoted about (212) to a vertical position to aid filling. In modifications, the bags may be wound in a roll instead of stacked or be separated from each other by differentially speeded rollers before filling, the holes left in the interrupted seams either being retained for ventillation or being sealed by a reciprocating heat seal means.
