Title: Improvements relating to coordinate switches
IPC: H03K17/70
Filed: 1965-07-26
Abstract: 1,072,718. Electric selectors; semi-conductor switches. TELEFONAKTIEBOLAGET L. M. ERICSSON. July 26, 1965 [July 24, 1964], No. 31864/65. Headings H1K and H1L. [Also in Divisions H3 and H4] The switching elements in a co-ordinate switching matrix comprise semi-conductor devices which have a high or low resistance depending upon whether a setting current fed thereto is removed slowly or quickly. Such elements may, as described in Specification 1,070,411, be of the type which fuse when a given current is exceeded and return to a high-resistance amorphous or low resistance crystalline state depending upon whether the current is removed rapidly or slowly. The construction may comprise a base layer 7 (Fig. 3) carrying conductive strips X1-X10 coated with the semi-conductor material. This is covered by an insulating layer (3) (Fig. 2, not shown), a conductive screening layer 4 and a further insulating layer 5 carrying on its outer surface conductive strips Y1-Y10 arranged transversely to the strips X1-X10. Connections are made through apertures between the semi-conductor layer and the strips Y at each cross point, the connections not making contact with the screening layer. The telecommunication switching matrix circuit shown in Fig. 4 provides connections between LE and LK. To establish a connection a half-current pulse is applied to a gate GY under the control of a logic circuit STY and a slightly larger pulse via a gate GX under the control of a logic circuit STX. Gate GY is now opened and a slowly falling signal is applied from circuit A, the switching circuit path being completed by one of diodes D1-Dn. To break the connection a square current pulse is applied via the GX gate only from unit B.

Patent GB-1074731-A (GB)
Title: Wool treating process
Filed: 1964-08-06
Abstract: Wool is treated with chlorine and then with a preformed synthetic polymer which is either water-soluble or able to form an aqueous dispersion to reduce its felting shrinkage.  The chlorine may be derived from an aqueous solution of a hypochlorite and an acid or gaseous chlorine may be used.  0.1-0.5% by weight of chlorine may be reacted with the wool.  Suitable synthetic polymers are polyethylene imine, polyamide-epichlorhydrin resins, polyethylene and other polyolefines and polyacrylates.  When polyacrylates are used the curing of the polymer may be catalysed by the use of ammonium chloride, oxalic acid, magnesium chloride, sulphuric acid or zinc nitrate.  The chlorine treatment and polymer application need not necessarily be carried out as successive operations, the chlorination pretreatment under acid conditions being carried out on loose wool and the polymer later being sprayed on to the loose wool or when the wool had been woven or knitted up into a fabric, as an aqueous solution or dispersion. After impregnation with the polymer solution or dispersion the woollen material may be dried and then steamed in a semi-decatiser for 1-5 minutes to effect curing or passed through metal rollers heated to 150 DEG -400 DEG C.  After the chlorination the material may be treated with sodium sulphite prior to the treatment with the polymer.

Title: A process to manufacture crystalline synthetic zeolites for use as molecular sieves
IPC: C01B33/26
Filed: 1965-07-29
Abstract: Synthetic crystalline zeolite molecular sieves having an average pore diameter of 4-11 A<\>p are produced by mixing aqueous solutions of alkali metal silicate and alkali metal aluminate in the presence of a mother liquor containing crystallization nuclei of the zeolite from a previous synthesis, separating the zeolite gel produced from the mother liquor, homogenizing it e.g. by stirring 1-4 times per hour, and crystallizing it.  The mother liquor from both the filtration and crystallization stages may be recycled to the initial mixture e.g. by adding it to the aluminate before contacting it with the silicate, thus enabling the process to be continuous.  The solutions are preferably heated to 5-50 DEG  C. before mixing, and may be contacted at 5-150 DEG C. with strong agitation.
