IPC: C09D5/44
Filed: 1927-02-07
Abstract: 289,965. Williams, W. A. Feb. 7, 1927. Grant of Patent opposed. Latex, treating.-In the electro deposition of rubber or the like from latex, an electrolyte which will not readily cause coagulation, but will act as a self excitant between electrodes, is added to the latex and externally connected electrodes are introduced to effect deposition of rubber on the anode. Zinc oxide, sulphur, or the like may be added to the latex, which must be only feebly aJ.ka.line. In an example, to 20 cc. of latex preserved with ammonia, and having the alkalinity of a semi-normal solution of ammonia, is added 40 cc. of a solution of ammonium chloride containing 26 gms. of the chloride to 100 gms. of water. Electrodes consisting of a zinc anode, and a porous pot containing carbon and magnanese dioxdde as kathode are introduced and connected externally, whereupon rubber is deposited on the zinc.

Title: Time division telegraph switching system
IPC: H04L12/52
Filed: 1962-01-30
Abstract: 986,005. Telegraphy. KOKUSAI DENSHIN DENWA KABUSHIKI KAISHA. Jan. 30, 1962 [Jan. 30, 1961; Feb. 20, 1961], No. 3466/62. Heading H4P. A telegraph exchange connects the active inputs of a set of connections I 1 -I n  to desired outputs O 1 -O n  via a multiplex channel including a time divisional multiplex regenerative repeater. Calling inputs sampled by a unit 1 are compared with a " list " of engaged calling inputs in a register 48, and if an active input which is not registered is found it is assumed to be a new call and a " proceed to select " signal is sent to the caller. The caller transmits the number of the desired station, and this together with the caller's number is entered in the register 46 and associated with a vacant channel found by a line finder 45. The numbers are translated into binary code at 47 and passed to a connecting memory 48 where they are stored in a position associated with the vacant channel. The memory 48 controls the selecting of the input and output units 1 and 3. A signal sender 49 produces " proceed to select," engaged signals &c. Regeneration.-Each input signal (Fig. 4a), consisting of a 5 bit start stop signal 7¢ units long, is sampled by the unit 1 to generate the pulse train shown in Fig. 4b. Similar trains delayed by fraction of a pulse gap tp are superimposed to provide an input for the regenerative repeater 2 (detailed in Fig. 3, not shown). The repeater is constructed as a six-figure binary counter arranged to count the pulses of each signal on a time shared basis. A feedback loop ensures that the counter cycles in groups of-for example-eight pulses as they would with the perfect signals shown in Figs. 4a and 4b. The element 1 (Fig. 4A) for example is sampled near its centre and this output is produced and maintained for a correct element length as shown at 1 in Fig. 4 (i). Codes other than 5-unit start stop are mentioned. Several sets of similar apparatus may be arranged side by side and work transferred from one to another, e.g. during repairs.

Abstract: 925,575. Preventing incrustation; delivering measured quantities of liquid. DISTILLERS CO. Ltd. Jan. 22, 1962 [Feb. 4, 1961], No. 4281/61. Classes 106 (5) and 123 (1). A process for preventing the fouling by marine growths of an underwater surface, particularly of a ship's hull, comprises injecting a liquid growth deterrent under pressure and intermittently into a perforated pipe system, the liquid growth deterrent being ejected through the perforations to contact the underwater surface. Distribution of the liquid deterrent may be assisted by a gas supplied independently to the underwater surface as described in Specification 925,573. Non- return valves (Fig. 1, not shown), may be associated with each perforation as described in Specification 925,574. The preferred deterrents are kerosene and light diesel oils. A metering pump B draws liquid deterrent from a reservoir A and supplies it to a container C in which a plunger F actuated by spring H maintains the liquid under pressure. When a predetermined volume of liquid is reached in the container C the valve E is opened automatically for a short period allowing the injection of liquid under pressure into pipe-system D from which it escapes through the perforations to contact the surface to be protected. The pipe may be coated with a plastic material to prevent corrosion. Specifications 851,902, 852,268 and 852,882 also are referred to.
