Abstract: 1456624 Disinfecting S-G HESSELGREN 13 May 1975 [21 May 1974] 20212/75 Heading A5G Material removed from an infectious area, i.e. where virus, bacteria, fungus or germs are known to exist or are suspected of existing, e.g. in odontology, is continuously disinfected by passing the material through a disinfecting zone within which the material is treated with a microbiocide treating composition. A device for use in continuously disinfecting material removed from an infectious area comprises a disinfecting zone, conduit means to direct the flow of material through the disinfecting zone, there being a treating composition containing microbiocidal substances within the disinfecting zone. In the Figure, the device shown comprises a mouthpiece 1, which is connected via a suction tube 2 to a suction source (not shown), and a disinfection device 3 consisting of a through-flow tube 4 of such dimensions that its two end sections 5, 6 can easily be connected to 1 and 2. At least a part of the total length of through-flow tube 4 is surrounded by an outer casing 7 having a larger diameter than that of the tube 4 and the space 8 thus formed between 7 and 4 contains the treating composition containing microbiocidal substances; within the region covered by 7 the tube 4 is provided with perforations 9, the grain size of the composition in the space 8 being larger than the perforations. The treating composition may also contain surface active substances and/or corrosion inhibitors and/or deodorants and may be applied in the disinfecting zone by surface application, e.g. by partially painting or spraying, in a section of a through-flow channel passed by the material to be disinfected. The treating composition may be applied to a porous carrier provided in the through-flow channel within the disinfecting zone. The porous carrier may be provided continuously to release a certain quantity of the composition embedded therein or it may form a part of the actual through-flow channel or the carrier may be arranged to be detachably secured in the through-flow channel.

Title: Process for the production of polyesters containing phosphorus
IPC: C08G63/692
Filed: 1963-05-22
Abstract: Polyesters containing phosphorous are made by effecting an addition reaction between 100 parts of an unsaturated polyester and 10 to 600 parts of a phosphorus compound of formula <FORM:1039112/C3/1> in which R1, R2, R3 and R4 are aliphatic, aromatic, alicyclic or araliphatic radicals which may be halogenated (R1 and R2 possibly being combined together with ring formation), and in which R1 and/or R2 may also be hydrogen or an alkali metal.  The addition reaction is performed at 20 DEG  to 130 DEG  C. and in the absence of a transesterification catalyst.  The unsaturated polyester is one made by reacting (a) an alpha, beta-unsaturated dicarboxylic acid and (b) a dihydric alcohol and, possibly, (c) a monocarboxylic acid or monohydric alcohol, or (d) a tri- or higher polyfunctional polycarboxylic acid or polyhydric alcohol.  The unsaturated polyesters used in the examples were made by reacting (1) and (2) maleic anhydride and ethylene glycol; (3) fumaric acid, tetrahydrophthalic acid and 1 : 2-propylene glycol; (4) and (5) fumaric acid, tetrachlorophthalic anhydride and 1 : 2-propylene glycol; (6), (7) and (8) maleic anhydride, chlorendic anhydride, ethylene glycol and diethylene glycol; (9) fumaric acid, tetrachlorophthalic anhydride and 1 : 2-propylene glycol; (10) and (11) maleic anhydride, chlorendic anhydride, phthalic anhydride, ethylene glycol and diethylene glycol.  If all of the double bonds of the polyester are saturated with the phosphorus compounds, the polyesters may be processed together with phenolic, melamine, urea or epoxy resins or may be used as flame resistant additives in vinyl resins.  The phosphorus-containing polyesters still having double bonds may be copolymerized with styrene, diallyl phthalate, triallyl cyanurate, triallyl phosphate, diallyl endomethylene-tetrahydrophthalate, diallyl hexachloro-endomethylenetetrahydrophthalate or methyl methacrylate. Copolymerization may be effected in the presence of cyclohexanone peroxide or benzoyl peroxide possibly together with cobalt

The die has surfaces 23 corresponding to the outer configuration of the aerofoil portion of the blade and has ports 24 and chambers 26 for evacuation of the die. Root portion inserts 34 are placed in recesses 35 in the die, the preformed skin 30 which may be of boron filaments in a matrix of aluminium or titanium or alloys of either is placed against the surfaces 23 and the die is evacuated. The tubes 36 are inserted side by side in the skin, one end of each is sealed at 38 and a manifold 40 is attached to the other end. The die is placed in a vacuum furnace and heated to 1600 F. when the blade members are of titanium, argon is fed through the manifold to pressurize the tubes and the conditions are held to diffusion bond the tubes and skin to root portions and after cooling and removal from the die the blade is trimmed. Prior to assembly the blade parts are cleaned of oxide. Instead of pressurizing the tubes as before, sealed tubes containing liquid hydrogen, water, argon, air, carbon dioxide, lithium chloride, N- butane, mercury, or lithium chloride and sodium chloride may be employed, the contained material producing pressure when heated. In a modification the tubes have a configuration conforming to the internal configurations of the blade may be employed and in another modification support struts may be arranged between the tubes of the first construction.

Abstract: 1,184,211. Transistor frequency changers and amplifiers. GENERAL ELECTRIC CO. 4 May, 1967 [31 May, 1966], No. 20879/67. Heading H3T. [Also in Divisions G4 and H2] In a frequency changing system, the output from an oscillator of frequency F is amplitude controlled by a signal, and the resulting signal is sampled by a pulse signal of frequency f from a variable frequency oscillator to produce an output at the difference frequency F-f. Sampling circuit, Fig. 2, comprises a pair of transistors 29, 30 connected in series with the amplitude modulated signal path the bases of the transistors being switched by the trigger signal. The resulting output signal is then integrated by capacitor 37 and amplified by transistors 38, 39, to produce one phase of the output signal. Control signal circuit, Fig. 7.-The frequency of the pulse oscillator is controlled by a signal from a programmer and in order to control the amplitude of the output from the amplitude controlled oscillator this signal is also applied to the input of a limiter 63. The limiter output is differentiated by capacitor 64 and is then applied as an input to amplifier 71, 72, 81. The amplifier is such that either positive or negative input signal produce a positive output, due to either transistor 71 or 72 conducting. The amplifier gain may be made different for the two polarities of input signal by adjusting resistor 74, andthe output current with no input signal may be adjusted by resistor 66 to set the minimum amplitude for the output from oscillator 14.

Abstract: 1,146,262. Centrifugal separators; separating particles from gases. GENERAL ELECTRIC CO. 5 May, 1967 [23 May, 1966], No. 20971/67. Headings BIT and B2P. In a vortex separator particles separated from the main portion of a gas stream are extracted with a minor portion of the gas at the periphery of the vortex chamber and passed therewith through a secondary separator from which the gas portion is returned to a low pressure zone of the vortex chamber. The particles may be liquid or solid and the gas may be a vapour or a gas and/or vapour mixture. In a steam separator, Fig. 1, swirl and de-swirl vanes 3, 5 are mounted at the inlet and outlet of the vortex separator between the separator casing 2 and streamlined guiding members 4, 6. Separated water particles are extracted with a portion of the steam through annular slots 7, 8, 9 into annular collecting chambers 10, 11, 12 connected by pipes 13, 14, 15 to a common line 17 which opens into a secondary separator 18 having a baffle 16 and a constant liquid-level float valve 20. Constrictions 13a, 14a are provided in the pipes 13, 14 to prevent circulating flow from upstream to downstream slots due to the downstream decreasing pressure. Separated steam is led from the separator 18 through a return line 21 which passes through one of the swirl vanes 3 and communicates with a passage in the guiding member 4 opening at 22 into the core of the vortex formed in the vortex chamber. In a modification, Fig. 2, the secondary separator includes a screen 26 for trapping the water droplets which collect in a bottom part 27 of the separator and are removed through a valved conduit. In further modifications, the secondary separator may take the form of a corrugated plate separator or a centrifugal separator.

Title: Electric converters

Filed: 1937-07-29
Abstract: 499,411. Converting ; automatic regulation. SIEMENS BROS. & CO., Ltd., GRINSTED, W. H., and DOUBLE, H. S. July 29, 1937, No. 21006. [Classes 38 (ii) and 38 (iv)] In a converting arrangement, particularly for supplying D.C. to a telephone installation from an A.C. source, and comprising inductive windings (which may be smoothing chokes or saturating windings on regulating chokes) in series with the output leads, there is provided in shunt with the windings a circuit of such a nature that a sudden change in load current causes a change in the distribution of current between the windings and the shunt circuit tending to minimise the transient effect of the sudden change in load on the output voltage. In the arrangement shown in which regulating chokes I on the input side of the converter (comprising the transformer TRA and rectifier REB) are provided with saturating windings II, III connected respectively in series with the load and across the output terminals of a resistance bridge BB the input terminals of which are connected across the output terminals of the rectifier, the shunt circuit for the windings II comprises a choke CHT of relatively high inductance in series with a variable resistance YB. The latter enables the regulating characteristic of the chokes I as determined bv the windings II to be adjusted whilst the choke CHT, owing to its relatively large inductance, causes, when the load current suddenly changes, a relatively large change in the current in the windings II connected in parallel therewith and thus operates to minimise the voltage transient at the rectifier output terminals. Similarly in the case of a smoothing choke CHS connected in series with the output leads, a shunt circuit may be provided. In this case the shunt circuit comprises a rectifier, preferably of the dry plate type, the resistance of which varies so that its shunting effect comes into play or is increased when large non-alternating voltage components appear across the choke on a sudden change in load current. Specifications 388,772, 430,247, and 473,281 are referred to.
