Patent GB-974644-A (GB)
Title: A process for the production of bonded molecular sieve pellets
IPC: B01J29/60
Filed: 1962-10-24
Abstract: Molecular sieve pellets bonded with silicic acid are produced by forming a plastic composition from a molecular sieve zeolite having a water content of more than 8% and from an aqueous silica sol having a specific surface area between 150 and 400 m.2/g. (according to B.E.T.) and a concentration between 10 and 40% by weight (calculated on the SiO2), and then granulating drying and activating the plastic composition.  The water content of the molecular sieve zeolite is preferably between 16 and 20%, and said zeolite when suspended in distilled water preferably produces a pH value between 8 and 11.  The silica sol may be produced by ion exchange of sodium silicate and subsequent alkali stabilization.  The pellets of this invention are said to have the advantage that they induce surprisingly small amounts of by-products in the absorption of olefinic hydrocarbons. Activation of the zeolite is usually effected at 300-350 DEG  C. Specification 974,643 is referred to.

Title: Improvements in or relating to closure caps for bottle necks
IPC: B65D41/18
Filed: 1960-11-25
Abstract: 934,109. Bottle closures. P. V. L. SALMINEN. Nov. 25, 1960 [Dec. 10, 1959], No. 40517/60. Class 125(3). [Also in Group V] A bottle cap is formed in a mould as at Fig. 1 and fitted to a bottle neck as at Fig. 2; the inner sleeve 1 has material 1<SP>1</SP> drawn downward by removal of mould portion M2 in direction 'a'. The material used is preferably polyethylene, and should be impervious to carbon dioxide. The effect of drawing a portion of the material when it is partially set is to provide an integral portion of the inner sleeve which is softer than the remainder in order to facilitate better sealing between the cap and bottle. Specification 865,039 is referred to.
Patent GB-883958-A (GB)
Title: Improvements in or relating to the refining of crude iron
IPC: C21C5/32
Filed: 1958-12-16
Abstract: A three stage surface blowing pig iron refining process comprises blowing oxygen with low blast energy on to a charge in the presence of end slag from the previous batch till the carbon content reaches 3,5-2,5%, at least partially deslagging, adding slag forming materials and continuing blowing with low blast energy until the carbon content reaches 2-1%, completely deslagging, and forming a fresh slag and blowing with increased blast energy until the desired carbon content is reached.  During the first two phases the blast pressure may be less than 10 kg/sq. cm. and the blast nozzle located more than 1 met. from the surface, while during the second phase the blast pressure may be 10-15 kg/sq. cm. and the said distance less than 1 met.  A slag basicity of more than 50% CaO is maintained during the first two phases.  In a modification an amount of mill scale and/or iron ore is added at the end of the second phase in sufficient quantity to bring the FeO content of the slag more than 25%.  The slag is then allowed to react vigorously with the bath for a short while prior to its complete removal, and the third stage then carried out.

Title: Method of forming spherically headed terminal structures for a separable fabric fastening device

IPC: A44B18/00
Filed: 1968-08-27
Abstract: 1,235,503. Finishing fabrics. Y. CHIBA. 27 Aug., 1968, No. 40830/68. Heading D1S. Spherically swollen headed terminal structures are formed on thermoplastic pile filaments of a base fabric to engage loops of another fabric in a separable fastening device by heating to melt the tips of the pile filaments whilst a liquid layer is present upon the surface of the base fabric. The fabric, Fig. 1, with a weft 1A and a warp 2A has a woven thermoplastic filament 3A, e.g. polypropylene, to form pile loops 3B the tops of which are cut open by a blade on the top of a loop-forming moulding-bar K to form pile filaments. In one embodiment, Fig. 7, the fabric 1 is passed through a viscous liquid 5A, e.g. water containing starch, in a tank 11 so that a liquid film is retained by surface tension between the pile filaments as the fabric passes over a heater M. The liquid film is gradually evaporated and only the parts projecting therefrom will be melted to form the structures, Fig. 4 (not shown). In an alternative embodiment, Fig. 8, the fabric 1 passes through a heating liquid 5B, e.g. at 70C-80C, and is slid over the top of a plate H so that the pile filaments 3C project out of the liquid by a predetermined length.

[Also in Division F4] A valve in a liquid fuel torch (see Division F4) comprises a valve stem f and closure member e both formed from magnetic material and contained within a non-magnetic tubular body c having a different thermal expansion from the stem f and surrounded by a heating, magnetizing and fuel igniting coil h. The stem f having discharge orifices g screws into the body c causing the member e which may be spherical or conical to close on to a seat d intermediate the ends of the body c. When the coil h is energized, the valve opens due to the different thermal expansions and the magnetic attraction between member e and stem f overcomes any sticking tendencies. The fuel flowing through the open valve is controlled upstream by an adjustable member m and a seating o. The upper end of the coil h is connected to an insulated terminal i and the lower end is secured to the tubular outer casing a of the torch.

Abstract: 422,162. Treatment of seeds and growing plants; germinating-appliances. BECK, H., 14, Hermannstrasse, Zehlendorf, Berlin. May 7, 1934, No. 13793. Convention date, May 6, 1933. [Classes 6 (ii) and 58] Seeds are germinated and seedlings grown for fodder, without using soil, by periodically submitting the seeds and seedlings to the action of fertilizers dissolved in water and of weak electric currents. The electric currents are produced by placing electrodes of different polarities in the electrolyte formed of the seeds or seedlings saturated with solutions of fertilizers and electrolytic salts, and closing the circuit by connecting the electrodes together by a conductor. The current is regulated by varying the size of the electrodes and adding suitable electrolytic salts. The current is stopped periodically by drying the seeds and seedlings. The apparatus shown consists of a heat-insulating casing k containing containers h in which are flat seed-boxes a made of non- conducting material and having perforated or permeable bottoms b. Electrodes at the ends of each box a are interconnected by a lead. Warm water and fertilizer are supplied periodically from vessels through pipes n and valves o. The vessels l may have hinged lids m and the casing k may be closed by doors. The separate compartments may have hinged cover plates q provided with inspection openings. The Specification as open to inspection under Sect. 91 states that the dissolved fertilizers and weak electric currents may be applied simultaneously or alternately, and that the lead connecting the electrodes together may be provided with a plug connection for making and breaking the circuit. This subject-matter does not appear in the Specification as accepted.

Abstract: 1338801 Lasers MESSERSCHMITTBOLKOW-BLOHM GmbH 13 Sept 1971 [15 Sept 1970 (3)] 42477/71 Heading H1C A dynamic gas laser is pumped by a nuclear reactor, solar mirror or chemical reaction. Fig. 1, shows a closed circuit around which laser gas is pumped by a blower 13. A nuclear fission or fusion reactor 10 heats the gas to about 1000‹ C. to produce an inverted population in the gas. The gas expands in nozzle 30 and enters a resonator 40 where it lases. The gas is cooled at 12 before re-entering the blower. The population inversion may be achieved also be neutron bombardment from the reactor; uranium may be so placed in the resonator that it is bombarded, or direct bombardment of the gas may be used, Figs, 2, 3 (not shown). This may be used as the sole pumping energy, or to supplement an electrical pumping discharge. The nuclear reactor of, Fig. 1, may be replaced by a solar mirror, Fig. 4 (not shown). In the chemical laser of, Fig. 5, oxygen or air is injected into a combustion chamber 310 via pipe 311, and C 2 N 2 , CO or C 2 H 2  is injected via pipe 312. After ignition at 313, e.g. by a heated platinum coil, the combustion gases expand along nozzle 320, and the vibrationally excited nitrogen molecules cause an inverted population in CO 2  injected at 321 and 322. The resulting mixture passes through a laser resonator or amplifier region 330 before being compressed in a diffuser 340, and is finally exhausted to the atmosphere at F3. Carbon monoxide may be added with the CO 2 , and is similarly excited. Other fuels such as benzene or carbon powder may replace the combustible gases injected into the chamber 310.
