Title: High temperature polyurethane/urea elastomers
Inventor: WU WILLIAM W L
IPC: C08G18/76
Filed: 1995-07-14
Granted: 2002-11-26
Abstract: The present invention relates to molded polyurethane/urea elastomers, and specifically to improved polyurethane/urea elastomers having high temperature stability to about 140-150 ~C and low temperature flexibility at about -35-(-40) ~C, for use in dynamic applications. These elastomers are particularly useful for application in belts, specifically in automotive timing or synchronous belts, V-belts, multi V-ribbed or micro-ribbed belts, flat belting and the like. The polyurethane/urea elastomers of the present invention are prepared by reacting polyisocyanate prepolymers with symmetric aromatic primary diamine chain extenders, mixtures of symmetric aromatic primary diamine chain extenders and aromatic secondary diamine chain extenders, or mixtures of symmetric aromatic primary diamine chain extenders and non-oxidative polyols, which are all chosen to eliminate the need for catalysts via standard molding processes, and to improve phase separation. The polyisocyanate prepolymers are reaction products of polyols which are nonoxidative at high temperatures, such as polycarbonate polyols, polyester polyols, or mixtures thereof, with organic polyisocyanates which are either compact, symmetric and aromatic, such as para-phenylene diisocyanate, 1,5-naphthalene diisocyanate, and 2,6-toluene diisocyanate, or are aliphatic and possess trans or trans,trans geometric structure, such as trans-1,4-cyclohexane diisocyanate and trans,trans-4,4'-dicyclohexylmethyl diisocyanate.

Abstract: A protective plant covering comprises a sheet of flexible material having two opposing side edges, each with a plurality of fasteners,  such that,  with the material wrapped around the plant, the two side edges may be brought proximate to one another and adjustably fastened around the plant using the fasteners.   In the preferred embodiment, fasteners in the form of strings and capture devices are vertically spaced apart along one or both of the side edges in a manner which allows the material to at least partially overlap upon itself for enhanced protection. One or more fasteners may also be provided along the upper and lower edges of the material, to enable top and/or bottom closure mechanisms, or the ganging together of separate sheets to create a more extensive covering for larger plant varieties or groupings.   The outer surface of  the material may include visual indicia in the form of decorative floral imagery, enabling the invention to be less conspicuous when installed.

Title: Improved extrusion track for blinds
Inventor: CHOU TSER-WEN
IPC: E06B9/36
Filed: 1997-02-25
Granted: 1999-12-28
Abstract: The improved system utilizes a track (51 ) which has a bowed internal surface to prevent the wheel of the carrier (17) from frictional engagement with the side of the track (51). The curved surface (55) which faces the wheels (27) will not be engaged by the wheels (27) even where the carrier (17) turns to one side or the other. This is accomplished while leaving the innermost portions of the raceway (53) in the same width position with regard to the wheels (27) as is usual to prevent the carrier (17) from coming off-track. The tolerances for the inner corners of the raceway (53) opposing the wheels (27) may be reduced to further prevent the possibility of jamming in the track (51).

Abstract: A test clip is described with contacts (50) for engaging leads (26) of an IC (integrated circuit) device, wherein the contacts have lower lead-contacting parts (56) arranged in a single row (62) at a predetermined lead spacing S, and have header pins (60) lying in a header arrangement that allows connection to a standard instrument connector (40). Each contact has an intermediate portion (70) where the contact has a first offset part (72) extending in a longitudinal direction (L) by a distance S/2, and has a second lower offset partthat extends partially in a lateral direction (M) by a lateral distance S. The upper first offset part extends horizontally, with 90° angles (76, 78) at it opposite ends, so the contact can be installed by pressing on a shoulder (90) of the first offset part. The first offset part with 90° angles is formed by initially stamping the contact from sheet metal to form a stamped part with such angles and such first offset part. The second, lower offset part extends at an angle (B) from the vertical of about 45° so its opposite ends form angles of 45°, with the second offset part resulting from bending of the stamped contact. The contact intermediate portions (which contains the two offset parts) lie in a recess (104) at the top of the connector housing and are held in place by a header insert (106).
