Abstract: 641,049. Heating vehicles. AUSTIN MOTOR CO., Ltd., WEAVING, J. H., MOGFORD, R. D., and APPLEBY, W V. June 30. 1948. No. 17504. [Class 64(ii)] The invention relates to vehicle heating systems in which hot water from the cylinder-jacket is circulated through a heater 8 by a pump 6 which circulates water through the usual radiator 3 and in which the connection to the top of the radiator is fitted with a thermostaticallycontrolled valve 4 which, when the water is cool, cuts out the flow to the radiator, there being no bye-pass from the valve housing to the pump. According to the invention, the connections 7, 9 to the inlet and outlet of the heater 8 are controlled by a valve 10 or valves which allow water from the cylinder head jacket to the pump 6 to pass through the heater when positioned as shown or to bye-pass the heater as well as the radiator.

Abstract: 837,519. Filling and closing cartons. JAGENBERG WERKE A. G. June 2, 1958 [July 19, 1957], No. 17530/58. Class 94(1). A device for filling, folding and closing containers of paper, card or the like has a movable pocket for transporting the container from a filling device to a folding and closing means, the pocket comprising two parts each of which is individually movable and each of which can carry a container. A container 9, Fig. 7, is held in a two-part pocket 5, 6, beneath a filling device 1. When the container has been filled, folding plates 18 on the parts 5, 6 are actuated to cause a preliminary tucking action on the open end whilst the parts 5, 6 convey the filled carton to a folding and lapping channel 2 and then into a pressing and sealing device 3, Fig. 9. As the parts 5, 6, convey the filled carton into the device 3 a trip member releases the part 5 from the part 6 and the part 5 is drawn back to the filling device 1, Fig. 4, where it receives an empty container from a supply 21. While the empty carton in the part 5 in being filled the pocket part 6 is transported with its filled and sealed container away from the pressing and sealing device 3 to a position where the container is removed, Fig. 6. The now empty pocket part 6 then continues its movement until it locks with the pocket part 5 carrying a now filled container, Fig. 7. The sequence of operations is then repeated. Two or more filling devices may be used, in which case the pocket units are constructed to simultaneously receive two or more containers either one behind the other in the moving direction of the pocket or beside each other.

When the lower limit is reached the multi-vibrator 24, 28 is blocked by the circuit 22, 23 to supply a firing signal to the thyristors 5. The tappings 3 are chosen so that the difference between the upper and lower D. C. voltages produced by the rectifier 1 is smaller than the predetermined voltage range across the transistor 7.

Abstract: 1,163,431. Light modulators. MULLARD Ltd. 19 July, 1967 [22 April, 1966], No. 17758/66. Heading H4F. [Also in Division H1] An electrically controlled Q-switching element for an infra-red laser utilizes a block of Y1G cut to such a length that reversal of magnetization in the block results in a 90 degree rotation of the plane of polarization of an incident plane polarized infra-red light beam, i.e. a 45 degree block. In general the arrangement may be used to switch the intensity of a light beam between two intensities by positioning an analyser after the Y1G block, or as an optical isolator, Figs. 2 and 3 (not shown). The Q-switching arrangement, Fig. 4, employs two 45 degree blocks, one of which G1 is permanently magnetized along the light beam while the other G2 is equipped with a switching coil and magnetic circuit, placed between crossed polarizers R1, R2 in the laser cavity M1, M2 which contains laser rod N. If the magnetization of block G2 is switched parallel to block G1 the arrangement permits loss-free transmission. If the magnetization of block G2 is switched to the opposite direction the beam is absorbed in analyser R2. Instead of pure Y1G the iron may be partly substituted by gallium or aluminium, in particular the substitution product may comprise Y 3 Fe 5-x M x O 12  in which M is Ga or Al and x lies between 0À9 and 1À5, preferably about 1À2.

Patent GB-722258-A (GB)
Title: Chemical products
IPC: C08F2/22
Filed: 1951-07-27
Abstract: Polymeric polyamines are prepared by reacting ammonia or an amine having at least one hydrogen atom bonded to a basic nitrogen atom and having an aliphatic or cycloaliphatic substituent containing 1 to 8 carbon atoms, with a polyepoxy polymer of an ethylenically unsaturated monomer containing recurring oxirane units having a molecular weight of at least 800, and having at least one oxirane group attached laterally to the polymer chain per polymer unit molecular weight of 800 to 1500.  Amines specified are mono- and di-methylamine, mono-and diethylamine, butylamine, amylamine, allylamine, ethanolamine, diethanolamine, 2-ethylhexylamine, ethylene diamine, hexamethylene diamine, and cyclohexylamine.  The polyepoxy polymer is preferably obtained by polymerizing monomers containing oxirane groups such as glycidyl acrylate, glycidyl methacrylate, glycidyl sorbate, glycidyl vinyl phthalate, glycidyl allyl phthalate, glycidyl allyl maleate, glycidyl allyl ether, glycidyl vinyl ether, 1,2-epoxybutene-3, and allyl alpha, betaepoxyisovalerate, which may be polymerized alone or together with one or more copolymerizable monomers such as butyl acrylate, butyl methacrylate, methyl methacrylate, acrylonitrile, butadiene, chloroprene, vinyl acetate, vinyl ethers, styrene, vinyl chloride, and vinylidene chloride. Polymerization may be carried out in bulk or solution in solvents such as benzene, dioxane, or methyl isobutyl ketone, with the aid of catalysts such as alpha, alphaazodiisobutyronitrile or benzoyl peroxide, to yield polymers preferably in form of oily viscous liquids having molecular weights of 1000 to 3000.  By an alternative procedure polymers containing unsaturated hydrocarbon lateral groups may be peroxidized with peroxy-acids, such as peracetic acid and perbenzoic acid, to give oxirane structures. The reaction between the polyepoxy polymers and the ammonia or amines may be carried out at low, room, or elevated temperatures in the presence or absence of an inert solvent such as benzene, dioxane, or water.  The after-treated polymers are soluble in dilute acids and may be treated with formaldehyde to yield products which are rendered insoluble on heating.  The polyamine products may be used in coating, impregnating and adhesive compositions, as dispersing agents for waxes and oils, and as binders for printing inks and paints.
