Patent CA-2106006-A1 (CA)
Inventor: GOLDER THOMAS J
IPC: B60R22/10
Filed: 1992-03-13
Abstract: 2106006 9216394 PCTABS00016 The restraint (210) device includes an open ended tubular guide member (215) which is generally cylindrical or elliptical in cross-section and in which the interior surfaces (235) of the tubular member define a longitudinal passageway for receiving and engaging portions of both the shoulder harness (S) and lap portions (6) of a three-point vehicular restraint system. The guide member (215) exerts a laterally displacing force on the shoulder harness portion (S) of a three-point restraint system to re-orient the shoulder belt for use by adults of relatively small stature or children. In this manner, the repositioning of the shoulder belt (S) for use by children in particular may be accomplished without adversely displacing the relative position of the lap belt (L) particularly during impact conditions. The advantages of the restraint device are accomplished without adversely affecting the automatic adjustment capabilities of the existing automotive restraint apparatus or without requiring extensive modifications to the existing restraint.
Patent CA-2107359-A1 (CA)
Inventor: BAILEY RALPH P S
IPC: B25J17/02
Filed: 1992-04-06
Abstract: ABSTRACT         A computer aided design and manufacturing system comprises a platform suspended by means of three pairs of supportive legs which are coupled thereto at triangularly spaced-apart locations by means of three universal joints each of which couples to one end of each of the two legs of a respective pair, the two legs of each pair extending from their respective universal joint in divergent directions to spaced-apart locations in an overhead mounting whereat each leg is drivingly engaged by a respective gimbal-mounted electric  motor  arranged  to  move  the  leg  in  its  own longitudinal  direction.     The  platform  position  and orientation can thus be controlled by appropriate operation of the six leg drive motors.  A rotary indexing stage is mounted on the platform for rotation in the plane of the platform under control of a further electric motor and serves as a mounting for a stage providing for pivotal movement in a plane perpendicular to the plane of rotation of the indexing stage, such pivotal movement being effected under control of yet a further electric motor.  Mounted on the pivotal stage is a rotary tool holder arranged to be driven by yet another electric motor.  The various electric motors are precisely positionable under computer control for effecting automatic manufacture of an object by cutting the same out of a block of material by means of a tool held in the tool holder.

Patent CA-2112076-A1 (CA)
Inventor: HARTMANN ACHIM
IPC: C01G49/10
Filed: 1993-12-21
Abstract: A process for purifying an acidic technical-grade iron chloride solution formed from cyclone dust from the production of TiO2 in accordance with the chloride process by adjusting the pH with a first neutralizing agent and thereafter introducing the pH adjusted solution in a controlled manner into a solution containing a second neutralizing agent.  In this process undesired ions which are to be separated, such as chromium, vanadium, zirconium and/or niobium, precipitate in the form of efficiently filterable hydroxides which can be separated industrially under economical conditions by filtration.  The filter cake is non-hazardous and can safely be disposed of by dumping. Calcium carbonate is the preferred neutralizing agent, and the pH adjustment may also advantageously be effected by using scrap iron or by using iron sinters with reduction of any Fe(III) ions before the second neutralization step.
Patent CA-2117832-A1 (CA)
Title: Pendulum paper clock
Inventor: LANDRY ANDRE
IPC: G04B15/00
Filed: 1994-10-11
Abstract: The present invention relates to a paper clock comprising inter alia a frame structure, a pendulum and an escapement and impulse mechanism which are all made of thin cardboard.   This mechanism is composed of two elongated gravity arms that hang pivotally from the frame structure and  of  two  coaxial integrally  linked,  weight-driven tripodal escape wheels that are adapted to abut against fingers fixed to the gravity arms.  The pendulum oscillates between and is in alternate engagement by the bottom ends of the gravity arms to pivot the same and free the escape wheels to effect stepwise rotating movement and drive the hour and minute hands through a fraction of a turn on the clock dial of the paper clock.   One of the gravity arms acts as an impulse producer and comprises a sand-filled reservoir for greater inertia.  This impulse arm is raised by a spoke of the rotating escape wheels and strikes the pendulum rod when both are in their downward trajectory to give the pendulum rod the momentum it has lost during the last complete oscillation.   The whole clock is made of paper, except for the shaft spindles which are made of metal and the weights in the weight, pendulum and gravity arm which is sand.
Patent CA-2121659-A1 (CA)
Inventor: DOWN JAMES A
IPC: C12Q1/6844
Filed: 1994-04-19
Abstract: Methods for processing samples which may contain mycobacteria which are compatible with both conventional culturing techniques and nucleic acid analysis. It has been found that the harsh chemical treatment previously thought necessary to obtain efficient lysis can be eliminated without loss of lysis efficiency, thereby eliminating reagents which may inhibit subsequent nucleic acid-based reactions. Heat alone is sufficient to lyse mycobacteria, even in buffers which do not contain detergents, chelators, enzymes, etc.  Residual reagents introduced by conventional sample processing methods for culture can be successfully removed from the processed pellet without significant loss of microorganisms by at least two washings with saline, water, or buffers compatible with nucleic acid analysis and appropriate centrifugation.

Title: Transgenic animal models for alzheimer's disease
Inventor: WADSWORTH SAMUEL
IPC: A01K67/027
Filed: 1992-12-29
Abstract: The construction of transgenic animal models for testing potential treatments for Alzheimer's disease are described. The models are characterized by a greater similarity to the conditions existing in naturally occurring Alzheimer's disease, based on expression of all three forms of the .beta.-amyloid precursor protein (APP), APP695, APP751, and APP770, as well as various point mutations based on naturally occurring mutations, such as the London and Indiana familial Alzheimer's disease (FAD) mutations at amino acid 717, and predicted mutations in the APP gene. The APP gene constructs are prepared using the naturally occurring promoter, as well as inducible promoters such as the mouse metallothionine promoter, which can be regulated by addition of heavy metals such as zinc to the animal's water or diet, and promoters such as the rat neuron specific enolase promoter, human .beta. actin gene promoter, human platelet derived growth factor B (PDGF-B) chain gene promoter, rat sodium channel gene promoter, mouse myelin basic protein gene promoter, human copper-zinc superoxide dismutase gene promoter and mammalian POU-domain regulatory gene promoter. The constructs are introduced into animal embryos using standard techniques such as microinjection. Animal cells can be isolated from the transgenic animals or prepared using the same contructs with standard techniques such as lipofection or electroporation. The transgenic animals, or animal cells, are used to screen for compounds altering the pathological course of Alzheimer's disease as measured by their effect on the amount and histopathology of APP and .beta.-amyloid peptide in the animals, as well as by behavioral alterations.
