Patent NO-150919-C (NO)
Inventor: DAIRE MARC
IPC: C09K3/14
Filed: 1980-07-03
Abstract: The invention relates to a new class of high-hardness abrasive products and wear resistant parts based on alumina and aluminium oxycarbides. By fusing alumina in the presence of a carbonaceous substance and by controlled cooling, it is possible to obtain a large number of products in which the ratio  rho  of the number of carbon atoms to the number of carbon atoms plus oxygen atoms is between 0.01 and 0.50, and preferably between 0.02 and 0.20. These products are essentially constituted by primary alumina crystals in a eutectic matrix Al2O3 - Al4O4C or Al2O3 - Al2OC.

Abstract: 57 This invention is a method of color electrophotography in which toner images are superposed sequentially on a photosensitive material sheet to form a multi-color image by using a liquid developer. According to this method, the photosensitive material sheet is made to pass by a conductive doctor member and then by an air blasting member in sequence immediately after development, so as to form the multi-color image. By this method, the multi-color image can be formed in the condition that most of a excess developer is removed while a small quantity of carrier liquid containing no residual toner particles is made to exist as a uniform liquid layer on the surface of the photosensitive material sheet, and thus a clear image free from a fogging of the surface can be obtained.

Abstract: The present invention relates to a device for determination of the topography of a surface by measuring its normal vector point by point, as well as devices for determination of the curvature of the surface in these points, and for determination of the orientation, position, shape and size of holes in the surface. The said devices are based on the use of opto-electronic sensors (1; 1-2) for measurement of the spatial position of active light sources. The invention is furthermore based on an accessory tool (1; 4) consisting of a body (3a; 5), a minimum of two light sources (3a; 6-8) and three contact pins (3a; 10-12) or a plane contact surface. The contact pins or the contact surface positions the tool unambiguously onto a surface (1; 3). By knowledge of the positions of the light sources relative to the contact pins or contact surface of the tool, the orientation of this surface can be determined from the measured spatial coordinates of the light sources.

Granted: 1997-12-16
Abstract: In a first embodiment, the invention has a casing set in the frame of a door in confronting relationship to the latchbolt-confining housing of the door.  A bolt, translatable in the casing, is extended, by a solenoid, and enters the housing to prevent opening of the door.  A latchbolt position sensor, in the form of a dual-ended limb, monitors the position of the latchbolt.  Upon withdrawal of the latchbolt, from latching closure of the door, the limb actuates a switch to operate a time delay circuit component.          When the specified time delay set by the component has run its course, it cuts power to the solenoid.          Compression springs withdraw the bolt from the latchbolt-confining housing, to permit the door to open.

Abstract: In a radio pager, a power-backup memory is provided for storing messages. On receiving a paging signal, a message contained in it is stoted into the memory and the user is alerted with a first sound pattern. A specified label is attached to the stored message if it is not answered by the user within a prescribed interval. When the pager is turned off for battery savings purposes, the message is kept in the memory and when it is turned on again, the memory is searched. If a message attached with the specified label is detected, the user is alerted with a second sound pattern which is different from the first sound pattern. The different sound allows the user to quickly recognize that he is alerted by an uncompleted page.
