Patent CA-2028092-A1 (CA)
Inventor: TANAKA YUJI
IPC: H04N1/405
Filed: 1990-10-19
Abstract: A binary image processing apparatus includes a first level discriminating device which has a first input terminal for receiving an image signal having a level corresponding to the density of a pixel of the image signal. A second input terminal receives a signal indicative of a discrimination level so as to allow the discrimination device to discriminate the level of the image signal according to the discrimination level into binary data. A differential device is used for obtaining a differential value of the image signal at the pixel. A second level discriminating device is used for discriminating the level of the differential value by a predetermined discrimination level. A calculating device calculates, in response to image signals in the vicinity of the pixel, an average value of density levels in the vicinity of the pixel. Finally, a discrimination level changing device supplies the average value to the second input terminal of the first level discriminating device and retains the discrimination level inputted to the second input terminal of the first level discriminating device when the differential value exceeds and is not more than the predetermined discrimination level.

Title: Oral hygiene composition
Inventor: LIBIN BARRY M
IPC: A61K8/46
Filed: 1990-11-23
Abstract: ORAL HYGIENE COMPOSITION               Inventor:  Barry M. Libin, a citizen of the United States and resident of Bellport, New York ABSTRACT OF THE DISCLOSURE     An oral hygiene composition that when brushed on or otherwise applied to the surface of teeth and adjacent gum tissue acts not only to bleach the teeth but also to improve the condition of the gums.  The composition includes both magnesium peroxide and magnesium hydroxide, the magnesium peroxide, when activated, being capable of releasing active oxygen to effect a bleaching action removing stains from the teeth surfaces and to whiten and brighten them, and at the same time to oxidize and destroy anerobic bacteria associated with dental plaque.          The magnesium hydroxide renders the pH of the magnesium peroxide alkaline, whereby the composition, when stored in a toothpaste tube or other sealed container remains inactive, and is activated only when the composition is applied orally and rendered acidic in the mouth by saliva.

Inventor: KIDD JOSEPH C
IPC: B60K13/04
Filed: 1991-04-26
Abstract: ABSTRACT OF THE INVENTION         A multi-component heat shield is provided.  The shield includes at least one heat insulating component and at least one heat reflecting component having different coefficients of thermal expansion.  The insulating and reflecting components are arranged with at least a portion of one of the insulating component's surfaces in registration with at least a portion of one of the reflecting component's surfaces.  Movement of the components relative to one another is restricted at selected positions while the movement of the components is unrestrained between these positions.  As heat is applied to the shield, the component with the greater coefficient of thermal expansion tends to expand at a greater rate than the component having the lower coefficient of thermal expansion.  The stress which develops in the shield due to the restriction of the components at the selected positions is accompanied by changes in the spacing between the components.

Title: Molded element
Inventor: SCHOLTA WINFRIED E
IPC: E01C5/00
Filed: 1991-08-27
Abstract: Abstract of the Disclosure: 1.      Multifunctional molded block 2.1     Individual elements of flagstones or lattice-type blocks for lawns may be pressed into the earth by heavy loads owing to their vertical contact surfaces. In the course of time, this leads to irregularities which cause a  high  level  of  accidents  and to considerable  soil compaction. The novel molded base elements, preferably produced from recycled plastics, together prevent this as a result of their inclined contact surfaces. 2.2     This is achieved by shaping the base module so that it is open on one side, limited by side walls (S1, S,  S2),  rhomboid  (SF1+2)  in longitudinal section and polygonal and/or arc-shaped in cross-section. Additional slots, holes or grooves extend the load-bearing capacity and functionality to meet requirements. 2.3     As a result of any desired combination with one another and connection to one another, individual base modules permit horizontal to vertical consolidation of soils so that they have a high load-bearing capacity, and also permit planting as well as a free-standing, self-supporting three-dimensional lattice construction. 3.
