Title: Titanium alloy surface prepn. for bonding - comprises degreasing, pickling and treatment with acidified fluorides
Inventor: VILLAIN ROLAND ROMEO FRANCOIS
IPC: C23C22/34
Filed: 1975-03-28
Abstract: A process for ensuring the adhesion of coatings, welds, etc. to parts contg. Ti at least at the surface is described. After degreasing and pickling the Ti surface is immersed in a bath contg. fluorides in an acid medium. The Ti surface is then rinsed in demineralised water at >=50 degrees C. Ti alloy surfaces can be treated to obtain good adhesion of organic or inorganic coatings such as paints, varnishes, enamels, cermets, or metals. The treated Ti surface is also suitable for welding or brazing. The first layer obtd. on the Ti surface is a Ti fluroide complex and the third treatment stage of immersion in an acidified fluoride bath removes this first layer allowing Ti hydroxides to form. TiO2 in the form of stable anatase is formed and shows excellent adhesion to polymeric adhesives e.g. polyimides.

Title: Heat pump for air conditioning - with air heated in two stages using two heat exchangers and has alternative vaporising and condensing circuits
IPC: F24F3/147
Filed: 1975-09-11
Abstract: A heat pump for room air conditioning to suit summer or winter conditions has a refrigeration unit which circulates the refrigeration fluid on one direction only around a circuit so that air is either heated or cooled. The air is heated in two successive stages by two separate heat exchangers without mixing the air and the refrigeration fluid. The heat is extracted from the stale air extracted from the room being air conditioned, before it is finally expelled. The flow of air is selectively directed by a set of control flaps, so as to form two treatment circuits at different temperatures. The vaporisation of the refrigeration fluid is brought about sometimes in the heat exchanger for the air, and sometimes in the heat exchanger for the refrigeration fluid. Also the condensation is brought about by alternative heat exchanger arrangements.

Title: Comparison of characteristic patterns in fingerprints - utilising marking system with binary coding and counter
Inventor: ELLIOTT JOAN
IPC: G07C9/00
Filed: 1975-11-07
Abstract: Examples of finger print characteristics are handled automatically by a comparator with the aid of binary coding. The method entails preparation of characteristic lists with data for identification of each salient symbol. The listed information contains data about the mark, its rough direction and the x-y coordinates. Main markings are differentiated from the secondary markings and a chain summation of these is made. Finally an evaluation of the markings is carried out and a classification cypher allotted. These cyphers are coded in a binary form in order that the process of companion can be made with a counter. This system can be used for other complex patterns such as molecule structures, maps and photographs.

Title: Dobby treadle selection - has gearing to prevent parts from turning at high speed when auxiliary motor is running
IPC: D03C3/28
Filed: 1976-07-08
Abstract: Mechanism for treadle selection between a loom and a dobby or another loom, uses an auxiliary motor with a clutch to engage or disengage the motor shaft with the loom and dobby. Two toothed flanges are keyed to the shaft of the dobby or the shaft of the loom. At least one selector grips in the holes of the flanges to ensure the keyed fit of the flanges. A rotary unit is operated by the auxiliary motor to control the sliding action of the selector. At least one of the two planetary rim gears carried by the rotary unit is a wheel set with a different toth count on the rim wheels. These act with a different tooth counts of the teeth of both flanges. The effect is that after holding fast of the flange keyed to the shaft of the loom, and after the selector has been pulled back and the auxiliary motor has rotated the rotary unit on the planetary rim gears, the planetary rim gears give the low speed rotation of the flange keyed on the shaft of the dobby, until the selector ranges again into the holes of the flanges. Smooth and simple selection of the operating mode is achieved without acceleration of the moving parts when the auxiliary motor is in operation.

Title: Automatic ground watering for plant growing - is controlled by humidity sensors with photocell preventing operation during daylight
IPC: G05D22/02
Filed: 1977-02-02
Abstract: Automatic watering of the ground for plant growing is achieved using luminous rays which cut off the supply in the absence of natural or artificial light. The amount of water is controlled by humidity sensors. A case (1) contains a photoelectric cell (5) which operates relays in the power supply circuit (8) to prevent operation during natural or artificial lighting. Wires (2) connect the electronic control circuits (12) to humidity sensors (3, 4) in the ground. When humidity level falls below a particular level, an electrovalve (9) operates allowing water to flow from inlet piping (10) via an outlet (11) to sprinklers. When humidity level rises the supply is cut off by operation from the sensors.
