Title: Improvements in or relating to primary or secondary electric cells or batteries
IPC: H01M4/24
Filed: 1958-11-03
Abstract: 907,660. Batteries. YARDNEY INTERNATIONAL CORPORATION. Nov. 3, 1958 [Nov. 7, 1957], No. 35270/58. Drawings to Specification. Class 53. A primary or secondary battery is provided with a negative electrode in which the active material consists of cadmium or a compound of cadmium with which a small quantity of metallic silver is mixed. The silver may be present to the extent of 2% to 10% by weight, and the mixture may contain polyvinyl alcohol or other thermoplastic binder. The positive electrode may consist of silver, and the electrolyte of potassium hydroxide, and the electrodes may be separated by a wrapping of polyvinyl alcohol or regenerated cellulose or by dividing the container into compartments by pleating the separator in zigzag as described in Specification 762,145. The negative electrode may be made by mixing cadmium oxide with powdered silver and an aqueous solution of polyvinyl alcohol. The mix is dried and half of it is placed in a die cavity and a silver grid or wire is placed on the surface of the mix. The remainder of the mix is then added and the whole compressed to form the electrode plate. Specification 808,007 also is referred to.

Title: Improved method and apparatus for producing fibres from glass and like heat-softenable materials
Inventor: WARTHEN WILLIAM PERRY
IPC: C03B37/022
Filed: 1962-09-18
Abstract: <PICT:0994163/C1/1> <PICT:0994163/C1/2> <PICT:0994163/C1/3> <PICT:0994163/C1/4> In glass fibre manufacture, a stream of molten glass flowed from an orifice is continuously drawn and alternated, giving a region adjacent the orifice a cone-shape, the con-shaped region being engaged with a heat - absorbing member so as to absorb heat from the stream, the rate of heat absorption normally being such that the cooled fibre retains a permanent impression from the member. A number of different shaped members are disclosed.  As shown in Fig. 4, molten glass drawn from ans orificed projection 14b at the base of an electrically-heated feeder forms a core-shaped region 26b and is drawn to a fibre by means such as winding the filament on a high-speed rotating collector sleeve.  The core 26b is engaged by co-operating dies 50, 52 to give a fibre 56 with the cross-section of the recesses 54 therein, i.e. to give an H-shaped fibre.  In a modification giving a flat film, the co-operating dies may be rotated to give a twisted flat film.  As shown in Fig. 9, a flat film 80 is formed by engaging the cone 26d by parallel rods 76, 78 which may be hollow to accommodate a cooling fluid. The rods 76, 78 may be curved or shaped to give, for example, an elliptical or hourglass cross-section or a grooved surface to the film.  As shown in Fig. 13, the member may be in the form of probes 94, either several as shown, or a single probe may be used, to give a groove or grooves, and the probes 94 may be mounted on a rotatable member 92 to give a grooved, twisted fibre 96.  The probes 94 may also be in the form of cutters which remove part of the glass of the cone 26f.  The probes may be arranged at different levels and may be arranged to give different depth grooves.  As shown in Fig. 16, a single probe 108 engaging the cone 26g of glass is reciprocally mounted with its holder 106 by means of a link 114 secured to an extension 112 and to a rotating disc 116 so that the tip 110 of rod 108 engages the cone 26g to give a series of indentations 118 in the filament 102.  The position of the rod 108 is adjustable in holder 106 by a set-screw 111.  Several rods 108 may be provided to give circumferentially spaced recesses 118.  The recesses or grooves may be coated with metal or alloy by using rods of metal or alloy fusible at a temperature below the temperature of the glass at the cone, the rods being continuously advanced towards the glass depending on the thickness of the layer of metal required.

Preferably the material is heated to a temperature at least 150‹ C. above its glass transition temperature; the time of heating is less than 15 sees. when the temperature of heating is near or above the softening point of the thermoplastic polymer and less than 1 sec. when the temperature is near or above the melting point of the polymer; and the filament is stretched by at least 5% its elongation at break during or after cooling. The filament may contain a liquid, gaseous or solid pore-forming agent which is preferably a swelling agent for the thermoplastic polymer and is applied prior to heating. Heating may be effected by infra-red, lasers, microwave, or with a liquid, gaseous or solid (fluidized bed) heating medium. In examples nylon 6 or 6 : 6 filaments are swollen in water, polyethylene glycol, dimethyl sulphoxide, moist air or ethanol, heated in ethylene glycol, paraffin oil, cetyl alcohol vapour, a fluidized sand bed or by infra-red for a time from 0À3 to 22 seconds at a temperature between 205 and 301‹ C. and are then cooled rapidly. In Example 9 a nylon 6 : 6 filament is cooled to - 60‹ C. in solid CO 2  and then rapidly heated for 0À3 secs. at 257‹ C. Example 10 relates to the production of a porous polyethylene terephthalate filament using cone. HCl as swelling/pore-forming agent and a heat treatment time of 3 seconds at 245‹ C.

Title: Improvements in the manufacture and production of aromatic amines from phenols
IPC: C07C209/18
Filed: 1930-12-04
Abstract: Motor fuels are rendered antiknocking by the addition of an iron carbonyl and an amine prepared by passing a crude phenol and ammonia over a dehydrating catalyst such as aluminium hydroxide at pressures above atmospheric pressure and at a temperature above 400 DEG  C. Suitable crude phenols are those contained in crude benzines from destructive hydrogenation products of hard coal, brown-coal or peat or tars therefrom such as brown-coal tar.  The aluminium hydroxide used may be compacted by making into a paste, drying and heating with phosphoric acid or aluminium nitrate.ALSO:Phenol or homologues thereof are converted into aromatic amines of the benzene series by passing them with ammonia over dehydration catalysts such as aluminium hydroxide at pressures above atmospheric pressure and at temperatures above 400 DEG  C.; pressures of from 50-300 atmospheres may be used.  The hot vapours coming from the reaction chamber are cooled and released to a lower pressure through a heat-exchanger into a collecting vessel whereby the liquefied ammonia is re-vaporized and separated from the amines, the ammonia being used again.  Crude phenols contained in crude benzines from destructive hydrogenation products of coals or tars may be used as initial materials in the process and the products may be mixed with iron carbonyl for the production of anti-knock additions for motor fuel.  In examples, (1) a mixture of crude cresol and ammonia is sprayed into a heated vessel lined with copper and charged with aluminium hydroxide compacted by making into a paste, drying and heating with phosphoric acid or aluminium nitrate; (2) a tube packed with a mixture of aluminium hydroxide and kaolin is used as in example 1; (3) the fraction boiling up to 230 DEG  C. of the phenols extracted by means of a caustic soda solution from crude benzine derived by destructive hydrogenation of brown-coal tar is treated with ammonia as in example 1; the resulting crude mixture of amines, alkylated if desired, comprising aniline, toluidines, xylidines, and some secondary amines may be mixed with iron carbonyl and added to pure benzines imparting an antiknock action; similar treatment may be applied to fractions boiling up to 230 DEG  C. of crude phenols extracted from aqueous bye-products formed in the low-temperature carbonization of hard coal, brown-coal or peat with the production of tars and from the aqueous bye-products formed in the destructive hydrogenation of these tars; (4) phenol and ammonia is treated as in example 2.
