Title: Coating sports grounds or playgrounds - using compsn. contg. vinyl acetate emulsion binder and catalyst
IPC: C09D131/04
Filed: 1975-02-24
Abstract: A coating is formed on a substratum, esp. for sports grounds or playgrounds, by applying a 1-5 mm thick layer of a compsn. contg. a vinyl acetate emulsion-based binder and 1-15 wt. % of a catalyst selected from acidic metal salts (e.g. Cr(NO3)3, ZrO(NO3)2, ZrO(OH)Cl), arylsulphonic acids (e.g. p-toluenesulphonic acid), AlCl3, ZnCl2 and NH4Cl. Also claimed are coating compsns., binders in which the emulsion is vinyl acetate homopolymer or copolymer with acrylic or maleic acid; and coatings on bitumen-coated substrates (e.g. concrete, wood). The catalysts allow the prodn. of relatively thick coatings with good cohesion and weather (esp. rain and sun) resistance using vinyl acetate emulsions instead of the more expensive neoprene. Aggregates of carefully controlled granulometry need not be used.

Title: Fitting of insulating sleeve to wiring - involves sleeving fed in at 90 deg. to 180 deg. to assembly oine and includes splitting blade
Inventor: BERAUDY PHILIPPE
IPC: H01B13/26
Filed: 1975-04-01
Abstract: The equipment allows the fitting of flexible or semi-flexible insulation to a group of parallel wires forming a multicore cable. Provision is made for further sheathing in screening or armouring layers. The individual insulated wires are grouped and run through an assembly stage preceeding enshrouding. Processing takes place entirely in a straight line excepting the feed of the sleeving material. This may be fed in from an angle of 90 deg. to 180 deg. to this line. Sleeving material is fed in at this angle from a store or directly from the extrusion process. A splitting blade followed by two planes cuts and opens the sleeving before it is fed over the cable bundle where it reforms naturally and is sealed by heating or gluing.

Title: Telephone keyboard integrated circuit operation during dialling - is enabled by relay which shunts listening and bell circuits
IPC: H04M1/31
Filed: 1977-07-04
Abstract: An electronic electromagnetic circuit allows the modulation and calling circuit to be switched off during dialling process from the telephone keyboard dial. this allows the specialised integrated circuit to continue operating during reduction of line current during dialling. Operation of dialling key causes output from integrated circuit (SN1) to cause transistor (T1) to conduct. A capacitor (C7) charges through bistable relay coil (RL) and relay shunts listening and bell circuits. When dialling ceases transistor becomes non conducting while another transistor (T7) becomes saturated and causes capacitor to discharge. The relay then operates in opposite direction to open contacts for conversation.
