Title: Ventilating fan control arrangement
Inventor: WRIGHT BRIAN WILLIAM
IPC: F24F11/00
Filed: 1987-10-01
Abstract: An extractor fan is responsive to a rate of increase of temperature in excess of a predetermined rate.

Filed: 1989-09-16
Abstract: A road marking composition is formed from a dry mix of a thermoplastic binder, aggregate such as crushed marble, a pigment such as titanium dioxide, and an exothermic material such as calcium oxide. When water is added to the dry mix the water reacts with the calcium oxide and produces an exothermic reaction to soften the binder. The main constituent of the thermoplastic binder may be a hydrocarbon resin, and one or more waxes may also be included. Other possible constituents include a filler such as calcium carbonate, and reflective glass beads.

Patent GB-907666-A (GB)
Abstract: 907,666. Anodizing and etching a film-forming metal; capacitors. WESTERN ELECTRIC CO. Aug. 18, 1960 [Sept. 21, 1959], No. 28635/60. Drawings to Specification. Classes 37 and 41. A method of making a capacitor having an improved dielectric oxide layer, e.g. a printed capacitor, comprises (a) anodizing a first electrode of a film-forming metal such as Ta, Al, Nb, Hf or Zr to form a dielectric oxide film thereover; (b) etching the metal at positions where there are irregularities or defects in the oxide film by immersing the electrode in a non- aqueous electrolyte comprising ions of at least one halide and biasing the electrode anodically; (c) reanodizing the electrode to oxidize the etched parts; and (d) disposing a second electrode such that the dielectric film is interposed between the first and second electrodes whereby the first and second electrodes and the dielectric therebetween form the capacitor. The etching electrolyte may employ, for example, CH 3 OH, C 2 H 5 OH, acetone, nitrobenzene phenol or aniline as solvent and salts such as AlCl 3 , LiCl NH 4 Br, KF, NaI and NaF as sources of halide ions. The etching current should be in the range 1-10 mA per sq. cm. and the etching may be carried out in one step at a voltage above the operating voltage of the capacitor being produced or in a series of steps at increasing voltages to a voltage above the operating voltage with reanodizing after each step. In one example of making a capacitor, Ta was sputtered on to a glass substrate and the Ta anodized in an electrolyte containing oxalic acid, water and ethylene glycol. Etching was in a solution of LiCl in CH 3 OH. After reanodizing, a counter electrode of Au was deposited in contact with the anodized surface. In other examples, solid electrolytic condensers have anodized Nb anodes e.g. coated with MnO 2  and wet electrolytics have anodized porous A1 anodes. Specifications 747,051 and 863,596 are referred to.

Patent GB-2265654-A (GB)
Title: Drop head
Inventor: DINGLER GERHARD
IPC: E04G1/04
Filed: 1993-04-02
Abstract: A drop head of a ceiling formwork has levers (33) connected pivotably to the supporting plate (14) and pivoting outwards as a result of their own weight and possessing locking projections (38). These engage in apertures (39) of engaging profiles (18, 19) on the formwork carriers (16, 17). The insertion of the engaging profiles (18, 19) is not impeded, since the locking projections (38) thereby shift aside. In contrast, separation necessitates a horizontal movement. If a formwork carrier (16, 17) therefore remains adhering to the concreted ceiling, the supporting plate (14) also continues to remain safely connected to the formwork carrier as a result of the interlock. An uncontrolled falling down of formwork carriers is therefore impossible, with the result that the risk of accidents is reduced. <IMAGE>
