Patent CA-2099755-A1 (CA)
Title: Deinking process
Inventor: MAH THOMAS C
IPC: D21C5/02
Filed: 1993-06-29
Abstract: ABSTRACT OF THE DISCLOSURE    Deinking of recycled waste paper, including magazine and other coated papers and office waste paper, is effected by mechanical  action through the  application  of shear forces to a slurry of water and the waste paper, causing the fibers in the waste paper to form pulp and the ink particles and other solid contaminants to be removed from the  fibers  and  to  be  sized  suitable  for  flotation separation.  The ink particles and other solid contaminants are separated from the pulp fibers by flotation.   The procedure provides effective deinking without the necessity for the use of chemicals.

Title: Jacket for a liquid-tight packaging of composite cardboard material furnished with a heat sealing plastics coating and method for its production
Inventor: DAMMERS MATHIAS
IPC: B65D5/42
Filed: 1993-11-09
Abstract: ABSTRACT          The invention relates to a jacket for a liquid-tight packaging of cardboard composite material coated with plastics and having a longitudinal seam.  To obtain a straight edge when an edge strip (4) of the layer disposed inside the seam is folded over, firstly composite material (7) is removed in a narrow inner zone, limited to the fold, along the folding line of the edge strip (4) to be folded over.  Such removal can be performed precisely, using inexpensive apparatus.  This creates the precondition for the production of a straight edge at the folding place of the folded-over edge strip (4).          Fig. 1 is intended for the Abstract.

Title: Low bend loss singlemode optical waveguide fiber
Inventor: ANTOS ANTHONY J
IPC: G02B6/036
Filed: 1993-10-27
Abstract: Abstract An optical waveguide fiber with improved bend loss performance while maintaining cutoff wavelength, .lambda.c, and zero dispersion wavelength, .lambda.o, in practical operating ranges. The fiber includes an inner core region with a refractive index delta higher than the rest of the core and a reduced diffusion tail at the core/cladding interface.

Title: Process for preparing emulsions that are polymerizable to absorbent foammaterials
Inventor: DESMARAIS THOMAS A
IPC: C08J9/00
Filed: 1992-08-07
Abstract: (SEE FIGURE) Disclosed is a process for the continuous preparation of high internal phase emulsions which are suitable for subsequent polymerization into polymeric foam materials that, upon dewatering, act as absorbents for aqueous body fluids. The process involves continuous introduction of a certain type of monomer-containing oil phase and a certain type of electrolyte-containing water phase into a dynamic mixing zone at relatively low water to oil phase ratios. Flow rates are then steadily adjusted to increase the water to oil ratio of the streams fed to the dynamic mixing zone while subjecting the dynamic mixing zone contents to shear agitation which is sufficient to thereby form a high internal phase emulsion that, upon subsequent polymerization, provides a foam having an average cell size of from about 5 to 100 microns. The formation of such a stable high internal phase emulsion is completed by feeding the contents of the dynamic mixing zone to and through a static mixing zone.

IPC: G09B13/04
Filed: 1993-07-13
Abstract: Educational devices using process-oriented educational methods are disclosed to prepare pre-school children, school children, and teenagers for keyboarding. The devices include sets of gloves and indicia applied to the fingers of the gloves to provide pictorial and alphanumeric representations of the computer keyboard. The visual and tactile memorization of the glove images are complemented by auditory and associative memorization provided by a story-telling educational method. Synergistic use of the gloves in the context of supervised story-telling also trains the pre-school children to develop and practice both lateral and vertical thinking skills (21-32), thus preparing them for coping creatively with the inherent hardware/software limitations of computers. The memorization of the alphanumeric representation of the computer keyboard is reinforced through synergistic use of the gloves in a variety of activities including learning the alphabet, learning word-spelling, and learning languages. To best fit the psychology of teenagers, a set of picture-rings is disclosed to specifically prepare that age-group for keyboarding.

Patent CA-2134482-A1 (CA)
Inventor: BRONSTEIN GARY D
IPC: B60R9/08
Filed: 1994-10-27
Abstract: There are several basic requirements for snowmobile carriers for small trucks, including easy operation of the carrier and gentle movement from the inclined loading or unloading position.  Because the vast majority of snowmobiles do not have a reverse gear, it must be possible to rotate at least a portion of the carrier so that the snowmobile can be driven from the carrier in a forward direction.  A relative simple carrier for meeting these requirements includes a base for mounting in a pickup truck box, a ramp removably mounted in the base for releasable attachment to the rear end of the base, a frame pivotally mounted on the base for movement between a horizontal carrying position and an inclined position, shock absorbers for ensuring gentle movement of the frame between the carrying and the inclined positions, and a platform rotatably mounted on the frame for alignment with the ramp in each of two positions for loading and unloading of a snowmobile in the forward direction.  The platform and the frame are releasably retained in the horizontal carrying position by a first latch which can easily be actuated by a user from the platform.  The platform is releasably retained in one position by a simple second latch, which is operated from the side of the truck before an unloading operation.

Inventor: OTT REINHOLD
IPC: G08B13/14
Filed: 1995-01-18
Abstract: The monitoring probe monitors goods in danger of being stolen. It has a sensor element to monitor a usual contact of the probe (10) with the goods. A connection cable (12) connects the probe (10) to a monitoring circuit of a theft prevention system. If the usual contact between the probe (10) and the goods is removed, the probe (10) provides a signal which can be evaluated by the monitoring circuit as an alarm situation. The probe (10) includes a flexible contact element (14) which normally lies flat on the goods and makes contact. Its shape is thus determined by the shape of the goods. The sensor element of the probe (10) comprises a wire strain gauge on which a force is exerted when the usual contact between the goods and the probe (10) is broken. Thus a change in the shape of the contact element (14) results in a change in the output signal.
