Patent GB-2049719-A (GB)
Title: Compositions for Coating Concrete, Mortar or Plaster Substrates
IPC: C08K3/38
Filed: 1980-05-14
Abstract: The compositions comprise polyvinyl alcohol and boric acid, preferably in amounts of 1 to 10% by weight and 0.1 to 3% by weight, respectively. The liquid vehicle is suitably water or an aqueous alcohol mixture. The alkalinity of the substrate causes the coating to form a gel which is both hydrophilic and insoluble in water. Where calcium ions are present in the substrate, these cause further increase in the water-insolubility of the coating. The gelled coating provides a very good primer layer for receiving further coating of plaster, mortar or concrete.

Title: Cooled aerofoil blade
Inventor: HOUGH GEOFFREY STEPHEN
IPC: F01D5/18
Filed: 1981-04-28
Abstract: A rotary aerofoil blade (10) is provided with closed cycle sodium cooling. The blade (10) has a shank portion (13) which contains a chamber (22) which is in turn partially occupied by an air cooled core member (21). The core member (21) serves to condense sodium vapour from the aerofoil portion (11) of the blade (10). Gutter members within the chamber (22) capture the condensed sodium as it is centrifuged towards the aerofoil portion (11) and direct it into a further chamber (31) within the blade shank portion (13) from whence it flows into passages (17) adjacent the external surface of the aerofoil portion (11). The high temperature of the aerofoil portion (11) vapourises the sodium which is then pumped by vapour pressure gradients back to cooled core member (21) whereupon the cycle is repeated. <IMAGE>
Patent GB-2098400-A (GB)
Title: Remote mains switching system
IPC: H02J13/00
Filed: 1981-05-13
Abstract: A remote mains switching system has socket outlets switched from a central location by signals that are transmitted to the socket outlets along conductors of the mains supply. Switching of the supply at each socket outlet is effected by means of a self- holding relay 7. A mild steel core (11) has mounted thereon a coil (10) including two windings (L1, L2) wound in opposite senses. The core is mounted on a yoke (12) which cooperates with a hinged armature (13) carrying switching contacts (MS1, 2) for the mains supply. The windings (L1, L2) are connected to a discharge capacitor (C1) through respective switching transistors (TR1, TR2). Upon switching on of transistor TR1, a current pulse produced in winding L1 produces a transient magnetic field that attracts the armature (13) to the core (11) and also produces a remanent magnetic field in the core (11) to retain the armature. Upon operation of the transistor TR2 an opposite transient magnetic field is similarly produced by winding L2 thereby destroying the remanent field and allowing a spring (17) to pull the armature away from the core. <IMAGE>

Title: Method and composition for cancelling luminescent address codes
IPC: B07C3/18
Filed: 1982-02-02
Abstract: A previously applied or erroneously applied machine-readable luminescent address code on a postal item 8 is cancelled by the application of an ultraviolet-absorbing ink. The ink is substantially transparent to visible light and includes a substance which absorbs ultraviolet light without luminescing and emitting visible light, and a binder which prevents the ink from soaking into the postal item to an extent such that the effect of the UV- absorbing substance is excessively attenuated. The ink absorbs the ultra- violet light directed towards the previously applied luminescent dot or bar code upon any subsequent interrogation by an address reading machine and so prevents that code from being read by a subsequent address reading machine. A particularly preferred ink includes a benzophenone to absorb the ultraviolet light. <IMAGE>
