Patent CA-2166141-A1 (CA)
Title: Automatic lubricant dispenser
Inventor: GRAF WALTER
IPC: F16N11/10
Filed: 1995-12-27
Abstract: A lubricant dispenser is disclosed for automatically dispensing a fluid lubricant. The dispenser includes a lubricant container adapted to hold the supply of a fluent lubricant, a lubricant displacing piston fittingly inserted into an open end of the container and movable therein for pressurizing the lubricant in and expelling lubricant from the container, and a gas generating cell consisting of an end wall which closes the open end of the container and has a cartridge seat, and a cartridge insertable into the seat. The end wall forms with the piston a substantially closed compartment holding a supply of reactive liquid and the seat opens into the compartment. A frangible partition is provided for removably closing the cartridge seat and segregating it from the reactive liquid-holding compartment. The cartridge which is insertable into the cartridge seat releasably contains a reactive element capable of reacting with the reactive liquid to form a gas for displacement of the piston. The cartridge has a unitary body of plastic material with a cylindrical collar received in the cartridge seat and moveable therein between a partially inserted position and a fully inserted position. The collar has a front end for engaging and breaking the partition of the cartridge seat when the cartridge body is moved to the fully inserted position. The collar further has a pair of diametrically opposite cutouts and a pair of reactive element retaining levers respectively pivotally mounted in one of the cutouts and pivotable between a reactive element holding position and a reactive element releasing position. The retaining levers each have a hook-shaped forward end directed toward the partition for engaging the reactive element and holding it in the cartridge in the holding position of the retaining arms, a rear end for engaging the seat, and a pivot intermediate the forward and the rear ends. The rear ends are shaped such that engagement thereof with the seat upon movement of the cartridge to the fully inserted position pivots the levers, thereby moving the respectively associated forward end into the reactive element releasing position. Thus, when the cartridge body is moved from the partially to the fully inserted position, the forward end of the collar breaks out the partition and the retaining levers pivot to release the reactive element thereby permitting contact of the reactive element with the reactive liquid for the generation of gas in the compartment to force the piston into the container for forcibly expelling the lubricant from the lubricant outlet. Thus, the functions of releasing the reactive element and breaking the frangible partition off the seat are separate which greatly simplifies the structure of the device. This makes it possible to form the cartridge body, the levers and their pivot of a single unitary piece of plastic, thereby greatly reducing manufacturing costs.
Patent CA-2166639-A1 (CA)
Title: Hanger
Inventor: PROTZ WILLIAM F JR
IPC: F16L3/13
Filed: 1996-01-05
Abstract: A hanger for positioning an object such as electrical wire or an ornament in remote locations such as in trees.  The hanger has a first loop shaped portion for releasably mounting the hanger on a support at a remote location.  The first loop shaped portion is a synthetic organic resin having a memory such that after deformation thereof the first portion returns substantially to its original shape.  A second loop shaped portion is integral with the first portion for holding an object such as a wire or an ornament; however, the second loop shaped portion is stiffer than the first loop shaped portion such that a pulling force applied to the object or to the second portion results in said first portion deforming and releasing the support while the second portion still holds the object.  The first and second portions each form loops open at one end to facilitate positioning the first portion on the support and an ornament or wire in the second portion.

Title: Methods of screening for beta-amyloid peptide production inhibitors
Inventor: SEUBERT PETER A
IPC: G01N33/50
Filed: 1994-10-17
Abstract: Processing of .beta.-amyloid precursor protein (.beta.APP) is monitored by detecting the secretion of a soluble amino-terminal fragment or .beta.APP (ATF-.beta.APP) resulting from cleavage of .beta.APP at the amino-terminus of .beta.-amyloid peptide. Secretion of ATF-.beta.APP in animal models may be monitored to identify inhibitors of .beta.-amyloid production.   The ATF-.beta.APP may be detected using antibodies and other specific binding substances which recognize a carboxy terminal residue on the fragment. Animals expressing the Swedish mutation of .beta.APP are described which produce abundant amounts of ATF-.beta.APP.

Patent CA-2182678-A1 (CA)
Title: Dispensing apparatus
Inventor: CATER MIRO STAN
IPC: B65D47/34
Filed: 1994-08-24
Abstract: A pump dispenser (101) connected to a container (107) of liquid has a first piston (3) reciprocatable in a first cylinder (5) for pumping a quantity of liquid at each depression of the piston. A valve member (8) received within a channel in the first piston is spring biassed into a position in which a dispensing outlet (19) is normally closed and is movable to release liquid in response to excess liquid pressure in the first chamber. A cylindrical extension (11) to the valve member defines a conduit (60) communicating with liquid in the container and is separable from the valve member to open a liquid inlet port (105) for recharging the first chamber. A second piston (39) is movable in tandem with the first piston and cooperates with a second cylinder (41) to provide suction on a return stroke of the pistons which is utilised to remove residual liquid from a dispensing channel (7) delivering pumped liquid to a nozzle (32). Residual liquid collected in the second chamber is returned to the container during the next subsequent actuating stroke of the pistons. The dispenser is particularly useful for water-borne liquid products because its self-cleaning action prevents clogging.

Title: Process and catalyst for producing polyolefins having low molecular weight
Inventor: SHAMSHOUM EDWAR S
IPC: C08F4/64
Filed: 1997-04-09
Abstract: The invention provides a metallocene catalyst for use in preparing polyolefins having low molecular weight.  The catalyst comprises   a   bridged   metallocene   in  which   one   of   the cyclopentadienyl rings is substituted in a substantially different manner from the other ring.  The catalyst comprises a metallocene compound generally described by the formula R"(C5R4)(R'2C5C4R'4)MeQp wherein (C5R4) is a substituted cyclopentadienyl ring; (R'2C5C4R'4n) is an indenyl ring or substituted indenyl ring; each R and R' is hydrogen or hydrocarbyl radical having from 1-20 carbon atoms, a halogen, an alkoxy, and alkoxy alkyl or an alkylamino radical, each R and R' may be the same or different; (C5R4) has one R substituent in a distal position which is at least as bulky as a t-butyl radical;  R"  is  a  structural  bridge  between  the  (C5R4)   and (R'2C5C4R'4)  rings to impart stereorigidity; Q is a hydrocarbyl radical, such as an alkyl, aryl, alkenyl, alkylaryl or arylalkyl radical having 1-20 carbon atoms or is a halogen; Me is a Group IIIB, IVB, VB, or VIB metal as positioned in the Periodic Table of Elements; and p is the valence of Me minus 2.   This catalyst produces a crystalline or atactic polymer with a low molecular weight and narrow or broad molecular weight distribution depending upon the isomer(s) used in polymerization.  A single threo-isomer produces  isotactic  polypropylene  and  a  single  erythro-isomer produces  atactic  polypropylene,  both  polymers  having  narrow molecular weight  distribution.    When  the bridge  between  the substituted cyclopentadienyl and the indenyl rings is substituted such that  four diastereomers  are possible,  the threo-isomers produce  isotactic  polypropylene  with  broad  molecular  weight distribution.
