Patent GB-2029765-A (GB)
Title: Method of Coating Surfaces of Buildings
IPC: E04F13/02
Filed: 1979-07-12
Abstract: A method of coating a surface of a building or of a building component which involves the use of a continuous mesh having interstices of a predetermined size and a settable paste comprising liquid binder and aggregate of predetermined sizes small than the interstices of the mesh, the method comprising the steps of applying the paste to the surface to form a layer of a depth greater than the thickness of the mesh, placing the mesh against the external surface of the layer and pressing it into the layer whereby, as a result of the predetermined relationship between the sizes of the interstices and the aggregate, paste including aggregate flows into the interstices of the mesh so that the coating thus formed comprises a homogeneous mass of paste extending behind and into the interstices of the mesh which is thereby embedded in it, and then allowing the paste to set. The mesh may be pressed completely into the layer of paste so that the coating has a continuous outer surface or a second coating may be applied.

Title: Switching unit for use with electric domestic immersion heaters
IPC: H05B1/02
Filed: 1979-08-03
Abstract: A control unit for domestic tank installed immersion heaters includes a self-latching relay (R1) connected in series with the immersion heater (H) and thermostat (TL).

Patent GB-2060332-A (GB)
Title: Rotatable spool fishing reel
IPC: A01K89/016
Filed: 1979-10-23
Abstract: In a fishing reel the spool 25 is disengageably connected to a drag gear 1 so as to apply drag to the spool 25 in one direction of rotation thereof only. A pinion 10 rotates with the spool 25 and drives a planet gear wheel 2 mounted for planetary movement between two positions in one of which it drives the drag gear 1 and in the other of which it does not. It moves between the two positions depending on the direction of rotation of the spool. The planetary movement may be caused solely by the action of the pinion 10 on the planet gear wheel 2. Alternatively it may be partially caused by surface contact between the spool 25 and the mounting element 3 for the planet gear wheel. The mounting element 3 may also be arranged so that the planet gear wheel 2 is counterbalanced. <IMAGE>
