Patent CA-2003808-A1 (CA)
Inventor: SEHM EUGENE J
IPC: C08F2/04
Filed: 1989-11-24
Abstract: Polycarbophil or crosslinked acrylic acid polymer is prepared in a solvent selected from acetone, alkyl acetates. and mixtures thereof, in the presence of an effective amount of divinyl glycol crosslinker, and in the presence of an effective amount of a suitable initiator allowing for polymerization to proceed at a temperature below 100°C at atmospheric pressure.      The polymer produced has average particle size of less than 10 microns without grinding, its viscosity is greater than about 50,000 cps when measured in water at 1% concentration, and it adheres to mucous membranes. By preparing the polymer in a non-aqueous solvent, the need for aqueous washing is avoided and the subsequent and enormous swelling of the polymer is avoided which means that prolonged and excessive drying inherent in the known processes is avoided.

Title: Portable decking unit
Inventor: HASSMAN KENNETH
IPC: E04B5/48
Filed: 1990-01-30
Abstract: ABSTRACT OF THE DISCLOSURE         A planar decking unit adapted to be attached to identical units to form a deck.  Each unit is molded of plastic as an integral unit.  The unit consists of parallel T-shaped members with transverse support members to provide rigidity to the unit.          Along the edges of the unit are alternate male and female connectors.  The male connectors consist of projections which are dovetail shape in cross-section.  The female connectors consist of recesses which are dovetail shape in cross-section and complimentary to the male projections.  The units are square and the connectors are positioned along the surface so that any edge of any unit can be connected to any edge of an adjacent unit.  The unit includes a foot or a base member situated on the bottom of the T-members which has a cross-section that is without sharp corners.  These base members or foot members reduce the area of contact between the unit and a surface on which it is situated to permit water to flow along such surface.  The shape of the base member or foot member tends to reduce the tendency of debris to become blocked by the unit.

Patent CA-2019146-A1 (CA)
Inventor: PLUMMER WILLIAM T
IPC: G02F1/13
Filed: 1990-06-18
Abstract: Method and apparatus which utilize an LCD modulator array for printing and/or enlarging an image recorded in a color film negative, a positive transparency or a color print, which LCD modulator array has pixels whose "closing time" (the time it takes to convert a pixel from a condition wherein it transmits radiation to a condition wherein it blocks radiation) is substantially longer than their "opening time" (the time it takes to convert a pixel from a condition wherein it blocks radiation to a condition wherein it transmits radiation). In accordance with the present invention, each pixel of the LCD modulator array is opened and closed in a rapid sequence, one after the other, at intervals which are much shorter than the closing time of the pixels of the LCD modulator array. The amount of radiation transmitted by each rapidly opened pixel is determined by detecting a spike of radiation which is transmitted through the rapidly opened pixel and by detecting and subtracting a background amount produced by radiation which is transmitted through other, slowly closing pixels.

Abstract: ABSTRACT OF THE DISCLOSURE           Method and apparatus for the handling of Loads using jaws pressed against the sides of the load.  In the procedure of the invention, the slippage between the load and the jaws is measured and the compressive force of the jaws is adjusted on the basis of the slippage.  The slippage is measured at least during a preliminary lifting performed before the load is lifted or at the beginning of the lifting operation.  During the preliminary lifting the load can be lifted at an essentially lower speed than during the main lifting operation.  The compressive force is increased during the preliminary lifting from a predetermined precompression value to at least a value at which the slipping ceases.

Inventor: SWICK CARL D
IPC: E02F9/28
Filed: 1992-03-16
Abstract: The invention is an improvement in a tooth assembly used with excavating and digging buckets such as those found in draglines, backhoes and the like.  Such tooth assemblies include a top portion (such as a wear cap), a nose protruding beyond the portion and a digging tip. The tip has high-hardness upper and lower exterior wear surfaces and a sharp-edged tip end for biting into earth, mineral and rock.  Either embodiment of the improved assembly involves mounting parts (a tip or tip and sleeve) directly on the nose.  In one improved assembly, a sleeve is interposed between the tip and the portion and includes high-hardness wear surfaces extending between tip and portion.  The tooth and sleeve cooperate to substantially entirely shroud the nose.  In another version having no sleeve, the tip includes high-hardness active digging surfaces extending substantially entirely rather than only partially between the portion and the tip end.  The tooth entirely shrouds the nose rather than being attached to the nose by a separate tip holder. With the improved arrangements, the tip and sleeve (or tip alone) comprise the primary replaceable parts and the nose is protected in that it is between high-hardness surfaces.
