Patent FI-823252-L (FI)
Inventor: LAKOS KAROLY
IPC: E05B37/16
Filed: 1982-09-22
Abstract: This lock comprises handling members which may be actuated according to a code, and a rack which may be displaced after actuating the actuating members controlled according to the code. Each actuating member cooperates with an insertion part which comprises at least a recess and which may be brought into two different positions. The insertion parts arranged according to the code prevent, in their start position, the displacement of the rack and, in their working position given by the cooperating actuating member, they allow the displacement of the rack owing to their recess or recesses. The insertion parts, which are not arranged according to the code, operate inversely. Thus, there is no resiliency difference between the coded and non coded actuating members and it is not possible to determine the code by groping.

Abstract: In a method for replacing tubes in a drum or header, without removing the whole tube entirely, the old tube (12) is cut off level with the header-member (14); a recess coterminous with the diameter of the tube (12) is machined into the header creating a seat for a new tube (16); the recessed old tube end (12) is beveled (17) and the old tube (12) is welded (18) into the header-member along the bevel. A new tube (16) is then inserted into the seat and welded (24) to the exterior of the header-member (14). A countersink (20) can be machined in the surface of the header-member to create a greater surface for welding of the new tube (16).

Title: Thermally stable thickener
IPC: C09D7/00
Filed: 1984-05-28
Abstract: A thermally stable thickener is composed of a stabilizing agent and a water dispersible polyurethane. The stabilizing agent is a smectite-type clay having a cation exchange capacity of at least 75 milliequivalents per 100 grams of clay, 100% active clay basis. The water dispersible polyurethane must possess the property that it forms an aqueous composition that experiences a decrease in Stormer viscosity upon thermal aging. Aqueous compositions incorporating the thermally stable thickener may be exposed to extended periods at elevated temperatures without substantially affecting the level of thickening.

Title: Sputtered semiconductor films of catenated phosporos¹material and devices therefrom¹¹phosphorus material.
IPC: H01L21/314
Filed: 1984-06-28
Abstract: Amorphous and polycrystalline films of KP15 are formed by RF diode sputtering targets of KP15 and excess phosphorus in an argon phase. Substrate temperatures up to 280 DEG -300 DEG C. provide amorphous films. Higher temperatures provide microcrystalline or polycrystalline films. These films have high resistance and may be used as the insulator in MIS devices employing III-V semiconductors. Co-sputtering with nickel increases the conductivity of the films from approximately 10-10(ohm-cm)-1 to 10-2(ohm-cm)-1; only reduces the optical gap by 0.2 eV; and reduces the activation energy from 0.8 eV to 0.2 eV; the nickel content varying from 5-15%. Substrates include glass, silicon, tantalum, stainless steel, gallium phosphide and gallium arsenide, and glass metallized with metals such as titanium, nickel and aluminum. Double diode electrical characteristics have been observed in devices formed on metallized glass substrates having co-sputtered thereon thin film polyphosphides and nickel with nickel and titanium top contacts.
