Filed: 1989-12-12
Granted: 1994-01-18
Abstract: ABSTRACT The invention provides a photosensor which com-prises a first electrode layer, a light-transmitting second electrode layer, and a laminate structure disposed between the two electrode layers and compris-ing a first photoconductive layer, a blocking layer and a second photoconductive layer for charge injection as a result of modification of the electrical properties of the first photoconductive layer and of the blocking layer, the main component of the first photoconductive layer being silicon, the blocking layer being made of a substance having a broader band gap as compared with hydrogenated amorphous silicon and composed mainly of silicon and carbon or mainly of silicon and nitrogen or mainly of silicon and oxygen, and the main component of the second photoconductive layer being silicon doped with an element(s) of the group III or V of the perio-dic table.     In this photosensor, the bright current can be increased while the dark current remains suppressed as in the conventional photodiode type photoelectric transducer devices.

Patent CA-2008564-C (CA)
Title: Wall with gravity support structure, building element and method for construction thereof
Inventor: JAECKLIN FELIX P
IPC: E04C1/39
Filed: 1990-01-25
Granted: 2000-02-22
Abstract: The wall according to the present invention comprises a gravity support structure with a plurality of compartments or cells which are filled with bulk-material and surrounded or subdivided by flat and flexible envelope material, and on one front side or on both opposite front sides of this gravity support structure a fore-part, preferably in the form of a supporting grid structure, which is positively or fractionally connected with said gravity support structure. Such combined wall structure can be used for slope supporting as well as for noise absorbing or partition purposes, in the latter cases e.g. in the form of a stand-alone structure. An essential function of the fore-parts is the protection of the front portions of the envelope material holding the bulk material filling against violation and solar irradiation. The stability of the combined wall is greatly enhanced by anchoring the fore-parts to the gravity support structure by means of comparatively inexpensive tensile elements.
Patent CA-2013221-C (CA)
Title: Preparation of phosphorous acid
Inventor: MCGILVERY JAMES D
IPC: C01B25/163
Filed: 1990-03-28
Granted: 1997-01-28
Abstract: Phosphorous  acid  is  formed  by  gaseous  phase oxidation  of phosphorus  with  water  vapour  to  form predominantly P2O3 and dissolving the P2O3 so-formed in water.  The P2O3 also can be recovered as the product by quenching the P2O3  to a stable temperature using an inert cooling medium rather than water.  Oxygen also may be  used  in  conjunction  with  the  water  vapour. Sufficiently rapid quenching of reaction products may result  in  the  formation of red amorphous phosphorus from unreacted phosphorus.

A device is provided for successively adhering the leading edge of the sheet material to the articles and a transverse parting wire serves to sever a predetermined portion of the sheet material so that it may be wrapped around the article as it rolls forward toward the conveyor. A method for wrapping cylindrical articles is also disclosed.
Patent CA-2015153-C (CA)
Title: Double bubble process for making strong, thin films
Inventor: SCHIRMER HENRY GEORGE
IPC: B29C55/22
Filed: 1990-04-23
Granted: 2000-07-18
Abstract: Polymeric, thin oriented films can be made by use of a combination of a hot blown process and a blown bubble process, i.e. a double bubble process. The resulting film has use in replacing PVC for in store stretch wrap applications. Very low density polyethylene, VLDPE, is an especially preferred material for this process. It may be used as a monolayer, or as one layer of a multilayer structure.      In practicing the invention, the polymer is extruded and hot blown, and heated to a temperature above its orientation temperature. This heating can be accomplished by the use of a heated liquid reservoir or sock disposed at the lower end of the primary bubble, inside the bubble. The hot blown heated film is then passed through a first set of pinch rolls, re-inflated into a blown bubble, and collapsed at a second set of pinch rolls. Thin, tough and elastic packaging materials are obtained by this process.

Title: Methods and apparatus for reducing the reactivity of articles destined for disposal
Inventor: MON JOSEPH M
IPC: H05K3/28
Filed: 1990-06-07
Granted: 1997-01-14
Abstract: Containers (20-20) which held UV curable acrylate materials commonly used as coating materials for drawn optical fiber are treated prior to disposal. Because of the presence of acrylate residues therewithin, the container cannot be disposed of in a landfill and has been incinerated. This problem has been overcome by exposing the residue within the container to suitable reproducible radiation determined in accordance with the photochemistry of the residue materials to cure completely the remaining acrylate material and thereby reduce its reactivity.
