Patent CA-2025947-A1 (CA)
Title: Label
Inventor: BOURGOIN ARMAN
IPC: G09F3/02
Filed: 1990-09-21
Abstract: ABSTRACT OF THE DISCLOSURE         The present application is directed to improvements with respect to articles which are to be folded about an edge of a substrate.  In particular, the invention is useful in multiple layer labels which have a plastic film cover of high tensile strength.  These types of labels, when wrapped about the edge of a substrate, have a tendency to return to a less folded condition and thus, the adhesive layer which maintains the label in contact with the substrate must continuously offset this internal force. According to the present invention, this is overcome by structurally weakening the label at a predetermined location during the manufacture of the label to allow folding of the label in this predetermined location.  This structure reduces the internal stress forces which tend to urge the label to a less folded condition.  The invention also has application with respect to reinforcing films or other reinforcing materials which have a tendency, when folded, to return to a less folded condition.

Title: Reaction injection molding apparatus with internal frame and shear edge
Inventor: WASZECIAK DOUGLAS P
IPC: B29C45/14
Filed: 1990-12-11
Abstract: ABSTRACT          Reaction injection molding apparatus for forming a fiber-reinforced molded article comprises a male die plunger and a female die part relatively movable between open and closed mold positions.  The female part has an upwardly opening die cavity, a surface around the cavity for supporting a batt of fibrous reinforcing material overlying the cavity, and a shearing edge defining the periphery of the cavity opening.  A clamp operates to clamp peripheral portions of the batt to the supporting surface, whereupon the die plunger is moved into the die cavity to press the overlying portions of the batt thereinto and into a mold formed between the male plunger and sidewalls of the cavity.  A cutter, also movable into the opening of the die cavity, has a shearing edge that cooperates with the first named shearing edge to shear excess portions of the batt at said periphery from the portions within the cavity and also to seal the mold for the subsequent injection of reactive chemicals into the mold, whereby 37,779-F     the batt therein is impregnated with the chemicals to form a fiber-reinforced article upon hardening of the reactive chemicals.   37,779-F

Title: Method to double the piezo - and pyroelectric constants of polyvinylinde fluoride (pvdf) films
Inventor: PERLMAN MARTIN
IPC: H01L41/45
Filed: 1990-12-11
Abstract: ABSTRACT         Polyvinylidene fluoride (PVDF) films and co-polymers thereof possess the highest values of piezoelectric and pyroelectric constants of any known polymer.  These films, up to present, have been first subjected to stretching and then to a high electric field (or corona charge) at an elevated temperature to provide a maximum piezoelectric constants (d31) of about 30-35 pC/N and a maximum pyroelectric constants (p) of about 3.5 nC/cm2K.  It has now been found that the piezoelectric constant and pyroelectric constant p of these films can be increased up to about 60 pC/N and 6 nC/cmZ K respectively when they are subjected to simultaneously stretching and corona poling with a poling field Ep = O.55MV/cm, a stretching ratio S.R. = 4.5X and a poling temperature Tp = 80 C.

Title: Drive system for impeller shafts
Inventor: GILBERT RONALD E
IPC: F04D29/20
Filed: 1991-01-17
Abstract: A~drive system for impeller shafts includes a coupling that has a universal joint that is lubricated under all operating conditions. A housing is connected to the universal joint, which housing includes a hollow end portion adapted to receive the non-threaded end of an impeller shaft. A threaded stud projects from the end of the shaft and into the housing where the stud is secured by means of a nut. The nut is readily accessible to the user so that the axial position of the shaft can be adjusted without difficulty. The nut is releasably held within the housing so that the shaft and stud, with nut attached, can be quickly disconnected from the coupling. The invention also includes a modified "square driven" configuration for the ends of the shaft that is extremely strong and enables the shaft to be connected to the impeller and the coupling very easily.

Title: Bionic-bloomer
Inventor: ALFORD JOHN M
IPC: A01G7/04
Filed: 1991-01-17
Abstract: ABSTRACT  Regarding the horticultural science of plant-growth stimulation, an electronic device can be connected between the rooting medium and a stem of a plant to control its development.  Flora development may be either augmented or diminished by selecting the proper polarity of the probe connections.  An electric potential produced between the plant's roots and the adjacent rooting medium assists the plant in the electrolyzing and assimilation of nutrients. This electrical assistance helps plants to thrive in poorer soil, lighting, and growing conditions than normally possible.

IPC: E05B65/463
Filed: 1991-02-27
Abstract: ABSTRACT          A latching mechanism for stacked drawer arrangements comprises operating parts for each drawer which are mounted on the drawer slide for the respective drawer.  Such an arrangement may allow any arrangement of drawers of different depths in a cabinet because no actuating parts are provided at fixed intervals on the cabinet.  A flexible band having slack length therein is provided on the cabinet over its height.  The band is deflectible by the actuating parts when a drawer is withdrawn to take up the slack length.  Thus, when one drawer is withdrawn, no slack length is available to allow withdrawal of another drawer.  Guides are provided on the drawer slides to maximize deflection of the band.     3628b/17

Title: Plasticizing and injecting unit for use in an injection molding machine
Inventor: HEHL KARL
IPC: B29C45/17
Filed: 1991-05-03
Abstract: ABSTRACT          PLASTICIZING AND INJECTING UNIT FOR USE IN AN          INJECTION MOLDING MACHINE         The plasticizing and injecting unit com-prises at least one hydraulic advance-retract actuator that is provided with external screw threads, which are screwed into internal screw threads of a bore formed in a carrier and supply block. Means for locking the advance-retract actuator in the bore in that the interengaging screw threads are wedged against each other comprise a plurality of lock screws, which are parallel to the in-jection axis and disoosed on a circle that surrounds the bore in which the actuator is received. Said screws can be tightened to different degrees so that the carrier and supply block and the advance-retract actuator are biased in mutually opposite senses and any deviations from a co-axial arrangement of the interengaging screw threads can thus arbitrarily be changed in its magnitude and direc-tion. As a result, the stresses which result in the over-all structure from a deviation from a coaxial arrangement can be minimized by a simple manipulation.

Title: Actuator plate type electrical switch actuating mechanism
Inventor: BARNARD DAVID A
IPC: H01H23/16
Filed: 1991-09-19
Abstract: ACTUATOR PLATE TYPE ELECTRICAL              SWITCH ACTUATING MECHANISM                 ABSTRACT OF THE DISCLOSURE     An actuator plate type electrical switch employs an actuating  mechanism  which  includes  an  overcentering cam,  sleeve,  actuator  plate,  plunger,  and  biasing spring.  The cam is rotatable between first and second overcentered  positions  and  has  an  actuating  lobe aligned with a contact assembly causing the assembly to assume  respective  contact  and  non-contact  positions upon rotation of the cam to corresponding first and second  overcentered  positions.    The  sleeve  has  a central  passage  and  a transverse  slot communicating with the passage.   The cam is received through the transverse slot.   The sleeve also mounts the actuator plate outwardly from the cam.  The sleeve and actuator plate are pivotal together about an axis which extends parallel  to the cam rotational axis.   The plunger, biased  by  the  spring  toward  and  into  continuous engagement with the  center of the cam,  is slidably mounted in the sleeve passage for reciprocal movement toward and away from the cam.  The center of the cam is aligned with the center of the actuator plate so as to define portions of the plate which extend in opposite directions  from  its  center  and  from the cam.   The plunger by being biased toward the cam and actuator plate imposes a force on the cam which urges the cam to rotate toward and remain at one or the other of the first or second overcentered positions in response to manually pressing on one or the other of the opposite portions of the actuator plate.
