Patent CA-2164714-A1 (CA)
Title: Composite, method and apparatus for making same
Inventor: RUDNER MYRON A
IPC: B29C43/00
Filed: 1994-06-15
Abstract: Methods of compression molding powdered polytetrafluoro-ethylene (PTFE) resins to produce composite articles having at least two distinct layers of PTFE resin, with each layer containing a different type of PTFE resin, are disclosed. A first layer of resin (100), preferably including a filter, is placed in a compression mold (200) and partially compressed at a relatively low pressure. A second layer of resin (102), preferably virgin (unfilled) resin, is then added to the mold and both layers are simultaneously fully compressed. After compression, the resulting composite preform is preferably sintered and coined to create a finished PTFE material or product. In a preferred embodiment, the partial compression step is performed at pressures of less than 500 psi. It has been found that modified PTFE resins provide improved resistance to cold flow and also provide better blending between filled and unfilled layers.

Abstract: Means and method for restricting the flow of oil which passes between the front bearing and the main shaft of an automatic transmission for motorized vehicles.  A gland is formed at the downstream end of the front bearing in either the inner surface of that bearing or of the housing into which the bearing is press-fitted.  A split ring made of thermoplastic material having  a  pressure velocity  value  in  excess  of  20,000  at 100 feet/minute surface speed is inserted in the gland and keyed in place against rotation.   The ring has a diameter which is slightly less than the diameter of the main shaft which it surrounds, and has circumferential gaps between its overlapping end portions which extend circumferentially .006"-.300" and has axial dimensions of .006"-.150".  The circumference of the ring is spaced radially from the opposed wall of the gland at least .0005".

Title: Olefin thermoplastic elastomer compositions
Inventor: KAWASAKI MASAAKI
IPC: A61J1/03
Filed: 1996-06-28
Abstract: An olefin thermoplastic elastomer compositions of the invention is in a non-crosslinked or crosslinked form and comprises a crystalline polyolefin resin (A) and an ethylene/.alpha.-olefin/nonconjugated polyene copolymer rubber (B), and optionally a softer (C) and/or an inorganic filler (D), in a specific ratio. The copolymer rubber (B) is prepared by the use of a metallocene catalyst and comprises ethylene, an .alpha.-olefin of 3 to 20 carbon atoms and a nonconjugated polyene. This composition can provide molded products of more excellent tensile strength, elongation at break, elastomeric properties (elongation set, permanent compression set, etc.), heat resistance and low-temperature properties than the conventional non-crosslinked olefin thermoplastic elastomers, even if the composition is in the non-crosslinked form. The composition in the partially or completely crosslinked form can provide molded products of more excellent low-temperature properties, tensile strength, elongation at break and elastomeric properties than the conventional vulcanized rubbers. The other olefin thermoplastic elastomer compositions comprises a crystalline polyolefin resin (E) and an ethylene/.alpha.-olefin copolymer rubber (F), and optionally an olefin rubber(G) and/or a softener (H), in a specific ratio, and is partially or completely crosslinked. The copolymer rubber (F) is obtained by random copolymerizing ethylene and an .alpha.-olefin of 3 to 20 carbon atoms in the presence of a metallocene catalyst and has (1) a specific molar ratio ((a)/(b)) of units derived from ethylene (a) to units derived from the .alpha.-olefin of 3 to 20 carbon atoms (b), (2) a specific density, (3) a specific melt flow rate and (4) a specific intrinsic viscosity (.eta.). This thermoplastic elastomer composition can provide molded products of more excellent tensile properties such as tensile strength and elongation at break than the conventional vulcanized rubbers.

Title: Transponder detector
Inventor: CHALOUX CHRISTIAN
IPC: G07C9/00
Filed: 1996-07-10
Abstract: The transponder detector has an antenna for radiating a power signal to an identification transponder of an unidentified type and for reading a response signal characteristic from the transponder. A plurality of power signal and response signal characteristic parameters associated with transponder communication protocols are serially selected and implemented while an analysis of the response signal characteristic is carried out to determine whether the response signal characteristic matches the selected parameters and to produce an identification match signal. The result of the match signal is displayed as text identifying the transponder make and model number on an LCD display, in the case of a hand-held universal transponder detector. The device is particularly useful for confirming the presence and type of transponders embedded in the head of keys.

Title: Process for preparing ethylene polymer and ethylene polymer
Inventor: TSUTSUI TOSHIYUKI
IPC: C08F4/6592
Filed: 1995-12-20
Abstract: The process for preparing an ethylene polymer according to the invention comprises homopolymerizing ethylene or copolymerizing ethylene and an .alpha.-olefin of 3 to 20 carbon atoms at a temperature of not lower than 80 °C in the presence of a catalyst comprising (A) a specific Group IVB transition metal compound, (B) (B-1) an organoaluminum oxy-compound and/or (B-2) a compound which reacts with the Group IVB transition metal compound (A) to form an ion pair, and optionally, (C) an organoaluminum compound.      According to the process of the invention, an ethylene (co)polymer having a high molecular weight can be obtained even at a high polymerization temperature. Further, since the polymerization can be carried out at a temperature higher than those in the conventional processes, a small-sized heat removal device can be used to decrease the equipment cost.

Title: Monitoring and imaging apparatus and method
Inventor: MCEWAN THOMAS E
IPC: A61B5/08
Filed: 1995-08-08
Abstract: A non-acoustic pulse echo radar monitor (1) averages a large number of reflected pulses to produce a voltage that modulates an audio oscillator (39) to produce an audible tone that corresponds to the heart (22) or other body part motion. Both amplitude modulation and the Doppler effect are used. A dual time constant is used to reduce the effect of gross sensor-to-surface movement. The monitor includes a pulse generator (10) for simultaneously inputting a sequence of pulses to a transmit path (12) and a gating path (14). The pulses on the transmit path drive an impulse generator (16) which generates pulses to a transmit antenna (18). The gating path includes a range delay generator (30) which generates timed gating pulses. The timed gating pulses cause the receive path (15) to selectively conduct pulses reflected from the body part (22) and received by a receive antenna (20). Both antennas (18)(20) are flat copper foils which permit their use in a substantially flat housing.
