Patent CA-2060540-A1 (CA)
Inventor: HUTTON RICHARD W
IPC: B65G19/24
Filed: 1992-02-03
Abstract: A  chain  for  use  primarily  in  conveyor  systems includes a plurality of male and female links pivotally coupled together.  The female link includes a generally I-shaped body segment and a pair of bifurcated arms at each end.  The arms are asymmetrically formed so that one arm defines a stop for preventing turning of the pivot pin and the other arm defines an enlarged boss.   The provision of the flanges along the body segment and the boss at the ends function to increase the bearing surface at points of greatest wear to thereby increase the useful life of the links.   The provision of the boss further obviates the need for spacers heretofore required in such chains of the prior art.

Title: Improvements in plasticising units for screw injection moulding machines
Inventor: MEYER PAUL
IPC: B29C45/48
Filed: 1992-03-25
Abstract: This invention relates to an injection moulding machine and to plasticizing units in the moulding press of the moulding machine for moulding plastics and rubbers.  The plasticizing unit comprises a screw and barrel, a compression zone and a plasticizing zone wherein the helical groove of the screw varies in cross-section such that the material is transferred from the screw into the barrel while being mixed and plasticized.  Furthermore there is a short second zone in which the flow area in the barrel outside of the cylindrical envelope of the screw reduces from full area to zero area for the material to be returned to within the cylindrical interface of the barrel.   The screw is axially movable for the injection action, such that the ram action of the moulding press is carried out by the screw itself.

Title: Tremblay clip
Inventor: TREMBLAY ROLAND J O
IPC: E06B1/60
Filed: 1992-03-30
Abstract: ABSTRACT          The "TREMBLAY CLIP" A device used for securing items that can only be installed form one direction.  Example;  Windows installed into most buildings are slid into the rough frame opening from outside. The moldings on the window stops it from going further than it is intended to. The window is normally nailed through this molding into the rough framing of the building. This then means you must fill nail holes and refinish the outside window finish. This is not possible in colder seasons, as most paints cannot be be used in wet or cooler temperatures. By using The "TREMBLAY CLIP" there is no need for nailing, therefore eliminating the need for a seasonal deficiency. The window can be pre-finished and then installed and left.

Patent CA-2069471-A1 (CA)
Inventor: MUNDIS JAMES W
IPC: B66F11/04
Filed: 1992-05-22
Abstract: The present invention comprises a hydraulic sensing means to be used in connection with a worm/worm wheel gear arrangement for articulating a boom mounted on a vehicle.  A hydraulic chamber on each side of the worm is formed by a bearing retainer and a piston.  A worm thrust in the direction of either hydraulic chamber increases the fluid pressure in that particular chamber, which causes the fluid pressure in a closed hydraulic circuit to increase.   The pressure increase is sensed by a fluid pressure gauge which sends a signal and/or terminates input power to the worm if the increase in fluid pressure is above a predetermined pressure.

Title: Method and apparatus for testing containers
Inventor: STIEGER OTHMAR
IPC: G06K1/12
Filed: 1992-06-03
Abstract: METHOD AND APPARATUS FOR TESTING CONTAINERS ABSTRACT          The apparatus for checking the volume of bottles (1) comprises a head (2) adapted to be moved sealingly onto the bottle mouth (21), with a metering piston (7) which is displaceable in relation to the head (2) to be inserted into the bottle (1) and compress the air contained therein, and a pressure sensor (9) for measuring the excess pressure produced in the bottle.  The measured volume (11) in the bottle is linked to a compensating volume (12) through a duct (10).  The compensating volume is determined on the one hand by the constant starting height of the metering piston (7) and on the other hand by the variable displacement path length of the head (2).          This ensures that the compression ratios are always the same for bottles of different heights, since differences of bottle height are compensated by a balancing piston (13) in the opposite direction, which alters the compensating volume (12) according to the sealing displacement path of the head (2) and thus always keeps the compressed measured volume exactly constant.  The apparatus enables deviations in volume occurring in a series production process for plastic or glass bottles to be determined without the need to supply external air to the bottles.  The measuring cycle is initiated by recording the pressure rise when the head (2) is placed upon the container (1).        (Fig. 1)

Title: Antibodies to ligand analogues and their utility in ligand-receptor assays
Inventor: VALKIRS GUNARS E
IPC: G01N33/541
Filed: 1991-09-04
Abstract: Means for the detection of free ligand analogue conjugate in fluids from competitive ligand-receptor assay processes. Li-gand analogue antibodies that bind the ligand analogue conjugate with substantially greater affinity than their affinity for target ligand are selected and used in competitive ligand-receptor assay processes to bind the free fraction of the ligand analogue conju-gate. This means permits the detection of the free fraction of ligand analogue conjugate even in the presence of substantially high-er concentrations of free target ligand. For the purposes of the present invention, ligand analogue antibodies are antibodies that exhibit at least 100 X greater affinity for the ligand analogue conjugate compared to their affinity for the target ligand.
