Abstract: 1,261,404. Electro-depositing resins. CHEMISCHE WERKE ALBERT. April 25, 1969 [April 25, 1968], No.21276/69. Heading C7B. A synthetic condensation resin is electrodeposited from an aqueous suspension of the powdered resin on to an electrically conductive surface e.g. of steel of Al. A phenolic resin e.g. a resol or novolak having a melting point of at least 60‹ C., a polyester resin based on an aliphatic or aromatic carboxylic acid having up to 18 C atoms e.g. tere- or iso-phthalic, adipic, sebacic, maleic or fumaric acid, a polyether resin, and/or a polyamide resin e.g. polycaprolactam, polyhexamethylene adipamide, a poly-#-lactam or polyundercanoamide may be used. The alcohol component of the polyester resin is preferably polyhydric e.g. (di) ethylene glycol, glycerol, trimethylolpropane or -ethane, dimethylolpropanediol or a butanediol or hexanediol. The suspension may also contain 0À01-5% (by weight of resin) of cationic, anionic or nonionic wetting agent, e.g. sodium lauryl sulphate, and a powdered pigment e.g. TiO 2 . Preferred operating conditions are: temperature between ambient and 50‹ C., current density of 0À1-30 mA/cm<SP>2</SP> and potential difference of 5-200 volts D.C. The pigment may be stirred into a melt of the resin and the melt cooled and milled prior to forming the suspension. The coating is preferably stored at a temperature above the softening temperature of the resin. For example, polyundecanoamide powder, or a polyester powder prepared by polycondensation of butane-1, 4-diol, ethylene glycol monobutyl ether, adipic acid and styrene-maleic anhydride copolymer and milling, is suspended and stirred in a solution of an alkylphenol polyglycol ether and sodium lauryl sulphate with n-octyl alcohol.

Title: Method and apparatus for determining the behaviour of a shock absorber arranged in the wheel suspension of a motor vehicle
IPC: F16F9/00
Filed: 1975-05-19
Abstract: 1496080 Testing vehicle suspension MASCHINENFABRIK KOPPERN GmbH & CO KG 19 May 1975 [18 May 1974] 21335/75 Heading G1N [Also in Division B7] A method of testing a shock absorber in a vehicle wheel suspension includes oscillating the wheel through a range of frequencies including the resonant frequency of the suspension, measuring the vertical wheel contact force to determine the minimum or maximum wheel contact force during oscillation, measuring the static wheel load and dividing the maximum or minimum contact force by the static load to produce a dimensionless factor from which is determined the performance of the shock absorber. Apparatus for carrying out the test comprises a wheel support platform 68 which is oscillated by two pairs of double-armed levers 48, 50 connected to a crank 42 which is coupled to a flywheel 38 driven by an electric motor. Each of the four corners of the platform 68 is connected to a respective one of the levers 48, 50 by a load transducer 72, 74 having two rigid vertical walls 82, 84 formed with tapped holes 86 by means of which they are attached-to the platform 68 and to a respective lever 48, 50, and two flexible horizontal walls 88, 90 to which are secured strain gauge strips 98. The strain gauge strips 98 are wired in a circuit, Fig. 6 (not shown), in which two of the strips at each corner of the platform 68 are connected cross-wire with strips at the diagonally opposite corner so that there is compensation for unequal loading caused by a wheel not being' centrally located on the platform. In a test stand comprising parallel ramps 4, 6 forming two tracks for the wheels of a vehicle, there are provided in the tracks two wheel support platforms 14, 16 which are oscillated by motors 26, 28 and are offset by a distance a so that the shock absorbers in the suspensions of the wheel on the two sides can be separately tested with the opposite wheel in  each case centred between transverse tubes.

Filed: 1932-07-29
Abstract: 393,116. Automatic circuit-breakers. NALDER BROS. & THOMPSON, Ltd., 97A, Dalston Lane, London, and GIBBONS, A. B., 77, Mayfair Avenue, Ilford, Essex. July 29, 1932, No. 21459. [Class 38 (v).] The main contacts 3 of an automatic circuit-breaker have in series with them a trip coil 1, an opposing coil 2 and a bimetallic strip 4 of magnetic material. On overload, a contact 7 on the strip 4 makes rapid contact with the tip 8 of a magnetized screw 6 to short circuit the coil 2 and allow the trip coil 1 to open the circuit due to the increased field. The coil 1 may have a larger field than the coil 2 so that on sudden large overloads the differential field will be sufficient to open the switch. The coil 2 may be replaced by a resistance, and the field of the coil 1 may be used to attract the element 4. Current setting is obtained by moving the screw 6.

Title: Improvements in or relating to a sewage treating process
IPC: C02F3/20
Filed: 1949-08-18
Abstract: 684,607. Treating sewage. INFILCO, Inc. Aug. 18, 1949 [June 11, 1949]. No. 21508/49. Class 111. [Also in Group II]. A process for treating polluted liquid comprising introducing polluted liquid to be treated, an oxygen-containing gas and calcium .carbonate into, and mixing them in, an aeration zone and separating clarified liquid from the solid portions of the mixture, is characterized by maintaining in the aeration zone a suspension of calcium carbonate in polluted liquid undergoing treatment, continuously introducing liquid to be treated, fresh calcium carbonate and oxygen-containing gas into the suspension and agitating the suspension to hold it against sedimentation and to disperse the newly-entering liquid and. oxygen-containing gas through the suspension, withdrawing a portion of the suspension from the aeration zone, separating clarified liquid from the withdrawn suspension, returning a portion of the solids of the withdrawn suspension to the aeration zone and withdrawing the balance of the solids to waste. The apparatus of Fig. 1 of Specification 679,635 may be used, modified by the addition of a pipe for introducing calcium carbonate with solid state or as a slurry into the raw sewage pipe just before it enters the tank, together with or instead of a pipe leading from the top of the tank to just inside one of the baffles in the aeration chamber. In the apparatus of Fig 1 of this Specification return sludge and calcium carbonate slurry are introduced into a pipe leading from the right to the centre of the base of the tank and air or oxygen is introduced at the left, the mixture being fed into the suction zone of a rotor and there dispersed. Calcium carbonate may also be added by a pipe shown on the right of the rotor. Mixed liquid is withdrawn from an upper launder and passed to a clarifier. The proportion of calcium carbonate to sludge may be varied over a wide range depending on the source of liquid being treated and the degree of purification required; for example it may be from 30 to 50 per cent of the suspended solids present. In the apparatus first referred to above the oxygen-containing gas may be introduced in an amount only just sufficient to establish air-lift action when the proportion of calcium carbonate is high. The calcium carbonate may be water-softener sludge or derived from reaction of lime with carbon dioxide, or it may be finely-ground limestone, e.g. dolomitic limestone. It may contain a considerable quantity of magnesium carbonate. The calcium carbonate may alternatively be added at spaced points if a longitudinal aerating basin is used. Specification 654,917 also is referred to.

Title: Improvements in or relating to methods for covering electrical components
IPC: H01G13/00
Filed: 1960-06-20
Abstract: 916,229. Capacitors. SIEMENS & HALSKE A.G. June 20, 1960 [June 18, 1959], No. 21560/60. Class 37. [Also in Group XXII] A method of covering electrical components, e.g. electrical capacitors includes the steps of guiding the components between a pair of cooperating forming tools, guiding a strip of covering material between each tool and the components, moving the forming tools in such a way that the two strips of covering material are brought into contact with each other on two opposite sides of the components and subsequently closing the remaining open ends. In an embodiment metal foil strips 1 and 2 are fed from rolls 1<SP>1</SP> and 2<SP>1</SP> over deflecting rolls 3 to two co-operating and oppositely rotating recessed bending tools 5 and 6. An adhesive is deposited continuously or intermittently on one side of each foil strip from storage vessels 7 and 8. Capacitors 10a are fed to the tools from a feed arrangement 9. In operation each foil is laid around one half of the external surface of the capacitor and the foils are welded by pressure or cemented where they meet on opposite sides of the capacitor. The tools may be heated to facilitate the jointing of the foil or a welding voltage may be supplied to the tools to enable the foils to be spot-welded. In another embodiment the capacitor is first covered according to the invention with foils of a synthetic material to form an insulating covering which is afterwards covered with metal foils. Alternatively metal foils coated on both sides with insulating material are used or foils comprising a synthetic carrier foil 15, Fig. 4, coated with metal foil in spaced-apart portions 16 which are coated with insulating material 17. Further operations, such as casting the open ends, testing &c. are carried out before severing the capacitor chain which operation may be effected in a feedmachine for printed circuits.

Title: Improvements in diffusion plants for making extracts from sugar beet, sugar cane andother materials
IPC: C13B10/10
Filed: 1926-09-02
Abstract: 258,849. Camuset, C. Sept. 25, 1925, [Convention date]. Extracts, making. - In a diffusion plant for sugar &c. extraction in which the liquid and the extractable materials are circulated continuously in opposite directions, separate heaters are provided to maintain the extraction liquid at a predetermined temperature at different parts of the apparatus. In the extraction of cut beet &c., the beet passes in succession through preliminary heating and extraction apparatus 1, 3 and two diffusion vessels A, B. The material drops from a cutter 24 into a hopper 1 which is filled with liquid from the vessel A up to a predetermined level 25, and is fed by screw 2 through a vessel 3 having a perforated double bottom which drains off the liquid to the first diffuser A. The liquid is circulated from apparatus 1, 3 by a centrifugal pump through a heater 6. The material is withdrawn from the vessel A, which has inclined sides to facilitate downward movement of the material, by a perforated screw or other conveyer 10 which is rotatable at different speeds and forces the solids into the second diffuser B. The diffuser B is tapered downwards and the material is fed upwards therethrough with the aid of a perforated screw or other conveyer 12 and the exhausted material withdrawn through a central telescopic tube 14 and pipe 15. A vertically movable stirring device 13 assists removal of the material which is then mixed with water in apparatus 16 and pumped to extraction presses. The liquid from the presses, at a temperature of about 30-40‹ C., is supplied together with. fresh water at a temperature of about 45‹ C. through pipe 17 to the second diffuser B, the press liquid being added either at the top. of the diffuser with the fresh water, or at other heights, for example through the perforated tube 18. Liquid from the discharging apparatus may also be returned to diffuser B. The liquid passes from diffuser B to diffuser A partly through conveyer 10 and partly through a perforated surface 11 and a heater 22, Fig. 2, an antiseptic, such as bisulphite of soda, being added if desired through pipe 26. A second perforated surface 11<a> may also be provided for withdrawal of the liquid from diffuser B. The liquid passes out from diffuser A through perforations 9 in the walls to the vessel 3. A centrally disposed perforated removal device 9<a> may also be provided. The liquid is finally withdrawn from the hopper 1 through the pipe 7. The operation is arranged so that the solids and liquid in diffuser B have substantially the same density. The liquid in diffuser B is kept at such a level as to set up a pressure which forces the liquid through the diffusers in opposition to the movement of the solids. The diffuser B has an exhaust valve 19. Thermometers 20, 21 and 23 are provided.

Title: Improvements in or relating to television cameras
IPC: G05D23/24
Filed: 1956-07-16
Abstract: 794,945. Electron beam apparatus. FERNSEH GES. July 16, 1956 [July 16, 1955], No. 21887/56. Class 39(1). A television camera comprises a pick-up tube which is surrounded by a shell, the space between tube and shell forming part of a closed air circulatory system and including means for heating said air ; in addition means is also provided for producing a second separate flow of air between the outer wall of the shell and the camera housing. In the drawing, the pick-up tube 2 is enclosed by the shell 5 which forms one chamber of the closed circulatory system. Another chamber is formed as two channels, one containing a heater 8, and the other a fan 6 and motor 7. There is thus no direct heat radiation from heater to tube. The heated air passes from the heater 8 into the shell 5 and around the tube, into the fan chamber and so back to the heater chamber. This closed cycle is dust-free, so that it may circulate between the face-plate 3 of the tube and a variabledensity light filler 11 without causing abrasion or dispersion. A second fan 14 and motor 13 draws air through openings in the camera housing 1, this second air stream passing through a circular passage 10, flowing round the outside of the shell 5 and then round various circuit components 15. The tube 2 is of the imageorthicon type, and requires to be maintained advantageously during operation at about 45 to 60C. The closed air stream is arranged to be heated rapidly up to the required temperature, after which it is automatically switched over to a lower rate of heating sufficient to maintain the tube at working temperature. This lower rate can be varied. If the camera is switched off for a short time and then on again, the heater is arranged not to revert immediately to full heating, since this may damage the photocathode. Control of the heater to operate as described is provided by the relay circuit of Fig. 2 (not shown). Specification 743,163 [Group XX], is referred to.
