Abstract: 1,167,595. Treating charge; spray carburetters; crank-case ventilation. B. WALKER. Oct.27, 1967, No. 49068/67. Heading F1B. In an I.C. engine exhaust gas is by-passed from the exhaust manifold 72 to the inlet manifold 26 when the engine is decelerating above a predetermined speed with the throttle valve 12 closed. Spring-biased diaphragm motors B and C, operated by the suction in the inlet manifold 26, open a valve 71 in the exhaust by-pass 73, 75, 78, 79 and move a member 45 to close a tube 31 supplying idling mixture and close a valve 87 between the exhaust manifold 72 and the exhaust pipe 50, respectively. The motors B and C are connected to the inlet manifold or atmosphere under the control of solenoid actuated valve member 61. The flow of exhaust gas through the by-pass is adjustable by means of a valve 76. Fuel for idling is fed to the needle controlled idling port 23 and needle controlled port 29 to the tube 31 from a float chamber 13 fed by a fuel pump. Fumes from the engine crank-case and air from the air cleaner A heated by exhaust heater 41 pass into the tube 31 past a valve 44. A spark plug 95 in the exhaust manifold 72 is operated when the valve 87 is closed.

IPC: G03C7/14
Abstract: 492,850. Colour photography. OPTICOLOR AKT.-GES. Dec. 7, 1937, No. 33864. Convention date, Dec. 7, 1936. [Class 98 (ii)] To avoid the production of an excess of a colour or colours where the area in the object is of small luminosity, the area or density of the zones of the multizone filter corresponding to these colours are reduced and the exposed film is developed in a developer to which substances such as solvents for silver halide are added which produce an increase of contrast between minute adjacent areas of the image representing different tone values, the resulting film being projected or printed using a filter in which the areas or densities of the zones are adjusted to produce a correct colour rendering. A. filter for the purpose is produced by making a filter in which the zones produce equal transparencies in the image layer when the film is exposed to a white object and reducing the size or transparency of the red zone in the case of studio portraits or the blue zone in the case of external scenes, by 25 to 30 per cent. After development as above, projection or printing is effected with a filter or light source producing an increase in the colour or colours previously reduced. An excessively bright green light may also be used during taking.

Title: Improvements in and relating to cellular polyurethanes
Inventor: WILSON PAUL IVAN
IPC: C08J9/02
Filed: 1967-11-01
Abstract: 1,214,478. Cellular polyurethanes. DUNLOP CO. Ltd. 24 Oct., 1968 [1 November, 1967], No. 49611/67. Headings C3C and C3R. Cellular polyurethanes in which the cells are formed at least partially by the evolution of carbon dioxide resulting from the action of water with NCO groups are prepared by mixing finely divided particles of man-made calcium sulphate dihydrate having no dimension greater than 100 microns with an organic compound having isocyanate groups and with any other polyurethane-forming ingredients, and heating the mixture to a temperature at which the calcium sulphate dihydrate liberates water of crystallization. The polyurethane foam may be made by the " one-shot " or, more preferably, the " prepolymer " process. Suitably, the prepolymer is prepared from polyethylene adipate and an excess of a diisocyanate so that the resulting prepolymer has a softening point below 90‹ C. The calcium sulphate dihydrate may be mixed with the prepolymer alone, but is preferably predispersed with a liquid polyether and a texture control additive such as a sulphonated castor oil derivative and then mixed with the prepolymer. The polyether is preferably poly(propylene glycol) diol. The calcium sulphate dihydrate may be prepared by adding a stoichiometric amount of 2N sulphuric acid slowly to a 40% aqueous solution of calcium chloride, followed by washing the precipitate to neutrality and then drying. Conventional diisocyanates and if desired catalysts and cross-linking agents are added to the reaction mixture.

Title: Improvements in and relating to the co-oxidation of cyclohexane and aldehydes
Inventor: LAWLEY HERBERT GEORE
IPC: C07D315/00
Filed: 1963-12-23
Abstract: Monocarboxylic acids, adipic acid and epsilon caprolactone are produced by co-oxidizing cyclohexane and an aldehyde in the liquid phase in the presence of a gas containing molecular oxygen at a temperature above 45 DEG  C. under such conditions that the molar ratio of aldehyde to cyclohexane in the reaction mixture at any instant does not exceed 1:10.  Suitable aldehydes are, for example, iso-butyraldehyde, adipaldehyde, benzaldehyde and tolualdehyde and, particularly, acetaldehyde, propionaldehyde and n-butyraldehyde.  The reaction temperature is preferably in the range 75-135 DEG  C. and the pressure should be sufficient to maintain the cyclohexane and the aldehyde in the liquid phase.  A liquid diluent may be present, e.g. an aliphatic carboxylic acid or ester or a ketone,if the aldehyde used is volatile.  If the temperature used is below 85 DEG  C. it is desirable that a catalyst should be present.  The preferred catalysts are those containing one or more transition metals and may be salts of organic acids. Products of the process other than those referred to above, may be recycled.

Abstract: 1493138 Optical fibre network PATELHOLD PATENTVERWERTUNGS UND ELEKTROHOLDING A.G. 26 Nov 1974 [28 Nov 1973] 51171/74 Heading G1A [Also in Division G2]  An optical fibre network comprises a solid lightconducting element 1, with transmitter optical fibres 4 and receiver optical fibres 5 optically connected to end-faces 1' and 1" respectively, and of such length that fibres 5 are illuminated by light from each fibre 4. Each station 2 contains a transmitter S, coding facility CT and optionally a receiver E with a photodiode. Transmitters S and addressing unit 3 have LED's. The information content of individual subscriber stations is sampled cyclically by Unit 3 via a network from the junction points of which optical conductors lead to the stations. When an address code is emitted it reaches all fibres 5 and when a called transmitter begins to operate its receiver is disconnected. Information from a transmitter is accepted only by stations programmed to the same address. The element 1 is of glass perhaps with a specularly reflective surface or coated with glass of a lower refractive index and of length such that light from each fibre 4 is distributed substantially uniformly among fibres 5 of the same optical density as the glass, and with the end-faces convex. The transmitter and receiver fibres may all be connected to the same end of element 1, the other end being reflecting, and for each station may combine into a single fibre near element 1. Stations may be in groups, with a coupling element per group. The elements are linked by fibres. Repeaters may be included.

The strands 102 are supplied from reels 104, Fig. 2, and pass via guides 106 through tension applying means 116a, 120 in a resin receptacle 125a whereby the strands are coated. Such coating may include a filler such as ground corn cobs. The strands may be threaded through perforated guide members 141-143, the central one of which is reciprocated to provide a layer of undulated strands; alternatively the strands may be crimped by heated rolls.
