Filed: 1971-05-05
Abstract: 1324952 Laminates STEEL CO OF CANADA Ltd 5 May 1971 [6 May 1970] 13319/71 Heading B5N A product suitable for the manufacture of cans comprises a steel substrate having a chromium/ chromium oxide composite coating thereon and intimately bonded to said coating the film of a polyolefin homopolymer, a copolymer of one or more olefins or a copolymer of a major amount of olefin with a minor amount of copolymerizable monomer having polar functional groups, the total amount of chromium in the composite coating measured as chromium metal and chromium-in-oxide being between 0À1 and 15 milligrams per cubic foot. Preferably the composite coating comprises a chromium metal layer adjacent the steel substrate and over that a chromium oxide layer. The film may be of polyethylene, polypropylene, ethylene/propylene copolymers or an ionized olefin copolymer in which interchain forces are developed between ionized carboxyl groups pendant from an alpha olefin chain and common metallic ions. The product may be made by heating a steel substrate having the chromium/chromium oxide composite coating thereon to a temperature in a range between the softening and degradation temperatures of the polyolefin to be applied, contacting the thus heated substrate with a polyolefin film and continuing heating in the said range while maintaining the polyolefin in contact with the substrate. The polymeric film is suitably maintained in contact with the heated substrate at the nip of a pair of rollers, and heating may be continued by means of an induction coil. In an embodiment the polyolefin film of the product may be intimately bonded to a second chromium/chromium oxide coated steel substrate to form a sandwich laminate.

Filed: 1947-05-20
Abstract: Acid-treated petroleum hydrocarbon oils are treated in the neutral state (and optionally after treatment with clay), with a normal alkali metal sulphite, whereby their corrosiveness to copper is reduced.  The sulphite is preferably in aqueous solution and the treatment may be carried out at a temperature of 40-100 DEG  C., and at atmospheric or raised pressure.  Oils specified are those which are more viscous than gasoline, including petroleum oils, a number of which are specified, synthetic lubricating oil of the simple or polymerized ester type, or mixtures of both. Examples of ester-type lubricating oils are acryloid polymers having a molecular weight of 8,000-10,000 polymerized esters of acrylic or fumaric acid with saturated aliphatic alcohols having 8-10 carbon atoms and co-polymers of maleates with fumarates or with vinyl acetate.  In the examples, a paraffinic base oil, a compounded hydraulic oil, and a Mid-Continent base white oil are treated with aqueous sodium sulphite after acid treatment and neutralization.  An example is given also of the treatment of a synthetic lubricant (di-2-ethylhexyl sebacate) with aqueous sodium sulphite.  The Specification as open to inspection under Sect. 91 refers also to the treatment of the oils with alkaline earth metal sulphites, either dry or in aqueous suspension.

May 25, 1949 [May 25, 1948; Sept. 20, 1948], Nos. 14044/49 and 14045/49. Class 102 (i). In a fuel - injection pump an insert 1 is fitted in the chamber containing the delivery valve 5 which is loaded by a spring 9. The insert has a restricted passage 2 which is less in crosssectional area than the delivery pipe 3 and as the speed of the pump increases, the lift of the valve 5 increases and eventually the abutment 10 approaches the insert 1 so that the area of the flow between the abutment 10 and the insert is less than the area of the passages 2 and the delivery is progressively reduced. In a modification, the projection 10 is of cylindrical form and upon increased lift of the valve, it enters, with clearance, the bore 4 in the insert; after entry, the reduction in the fuel delivery ceases.

Filed: 1922-05-19
Abstract: 201,679. Aldendorff, F. May 19, 1922. Electrostatic relays utilizing the attraction between a semiconductor such as agate and a contiguous piece of metal when a current is passed therethrough have the actuating part comprising the semi-conductor and metal mounted upon one side of a metal plate or support and the actuated part on the opposite side. A number of such parts may be arranged in rows on a long metal plate and made interchangeable. The connection between the actuating and actuated parts may be adjustable, and a lever arrangement may be used to give greater movement to the contact. On one side of a metal support 1 are arranged a layer of insulation, a layer of metal 5, the semi-conductor 6 and a metal spring actuating part 7, the parts 6, 7 being mutually attracted on passage of current which is passed through terminals 22, 23 connected to the parts 5, 7 respectively. Member 7 carries a pivoted member one arm of which is in the form of a spring 20 bearing against part 7, the other end carrying an adjustment screw connected through insulation 24 with the short arm of the actuated member 2 which is secured to the cross limb of an H-shaped spring support 8 which allows movement of member 2. The long arm of member 2 has a lateral extension 12 between contact springs 3, 4, moving away from the latter and contacting with the former when current passes. The upper ends of springs 3, 4 and the side portions of member 8 are held in a block, or between layers, of insulation 9, 10 fixed by screws 15. The movable spring of the actuating part may be straight and the semiconductor curved, or vice versa. The supporting plate with relays is mounted with the free faces of the semi-conductors directed downwards to keep them free from dust &c. According to the Provisional Specification the circuit closer of the actuated part may consist of two thin spring metal strips pressing against each other and engaging the fixed co-operating contact against which they rub like tweezers.
Patent GB-1131036-A (GB)
Title: Device for determining liquid volumes by measurement of the dilution of a radio-active solution
Inventor: LEROY MARCEL
IPC: G01T7/02
Filed: 1966-03-30
Abstract: 1,131,036. Volume measurement by radioactive solution dilution. COMMISSARIAT A L'ENERGIE ATOMIQUE. March 30, 1966 [March 30, 1965], No. 14197/66. Heading G1A. A liquid volume e. g. the blood volume of a human being, is measured by determining the dilution of a radio-active solution using a photodetector to measure the activities and thereby concentrations of samples before and after the dilution. In the determination of blood volume, the concentration of a radio-active marker in a solution is measured, the solution injected intravenously, and after a certain time, a blood sample taken and its concentration determined and compared with that of the original injection solution. Since the concentration of radio-active material is directly proportional to the volume it is contained in, the total volume of the vascular system into which the injection was made, may be determined. The invention seeks to provide for the great difference between the concentrations, and thus activities, of the blood sample and the original injection solution, but to avoid having to dilute the injection solution before determining its activity and thereby avoid errors due to radio-active decay before the injection can be carried out. The apparatus used comprises a movable tripod 1, carrying a housing 4 containing the detector system, a photo-multiplier 7 and a hollow, thallium-activated sodium iodide scintillation crystal 6. Lead shielding 10 is formed with a pedestal 14 in which a threaded column 12 turns freely on rotation by a wheel 15, causing a threaded nut 17 to move up or down the column. The nut is integral with a support plate 18 for a syringe 20, allowing the latter to be moved to the required distance from the detector system. The distance of the syringe support from the detector is adjusted so that the activity, measured by the detector, of a syringe full of the injection solution, is of the same order as that which will be recorded when a test tube containing a blood sample taken a certain time after the injection, is placed in the bore of the scintillator crystal 6. To obtain this distance a test tube of solution diluted to a known dilution, say 1 in a 1, 000, is placed in the crystal bore and the activity recorded. The same amount of the concentrated solution in a syringe is then positioned in the support plate 18 and the position changed until the same activity is recorded. A series of measurements may then be carried out without dilution of the injection solution beforehand, a first measurement of the injection solution being carried out with the syringe in the support plate and a second of a blood sample carried in a test tube in the crystal bore. The known ratio is taken into account when the activities are compared to calculate the blood volume.
