Abstract: Mammalian glycoprotein hormone-1 (Zlut1) polypeptides, polynucleotides encoding the polypeptides, antibodies that specifically bind to the polypeptides, expression vectors comprised of the polynucleotides, and host cells transformed with the expression vectors.

Abstract: A measurement scale (20) is movable in plane x relative to a mask (10) and photodetector (30). When a pattern of apertures in the mask (10) are in correlation with a pattern of apertures e.g. a reference mark in the scale (20) then light bands a b and c may propagate to the detector (30). The relative sizes of the patterns is such that the light bands converge at the detector (30). Other embodiments show light divergent and light inversion correlation of incongruent patterns.

Abstract: Described is a communications system in which messages may be processed using public key cryptography with a private key (SKu) unique to one or more users (150). The system comprises a server means (130) adapted for data communication with a client (110) via a network (100), the server means (130) comprising first data storage means in which is stored in a secure manner a private key for the or each user, the private key being encrypted with a key encrypting key. The server means further comprises second data storage means in which is stored applet code executable on the client. The server provides the applet code to the client via the network in response to connection of the client to the server via the network.

Abstract: Improved low density polyurethane foams are prepared from an isocyanate-terminated prepolymer having an NCO content of more than about 31 to about 33.5% by weight comprising:(a) a polyphenylene polymethylene polyisocyanate comprising(i) about 30 to about 100% by weight of diphenylmethane diisocyanate and(ii) the remainder selected from the group consisting essentially of higher homologues of polyphenylene polymethylene polyisocyanate, isocyanate-containing ester groups, urea groups, biuret groups, aliphatic groups, carbodiimide groups, isocyanurate groups, uretdione groups and urethane groups; and(b) a polyoxyalkylene polyol having an oxyethylene content of about 30 to about 90%, a molecular weight of about 1000 to about 12000 and a functionality of about 2 to about 8.

Abstract: A portable surface lift for a vehicle and a pair of manually retractable wheels respectively attached to a mid-portion of opposite sides of the lift for rolling the lift over a garage floor surface when the vehicle is not lifted on the lift. The lift has fixed pads for contact with the undercarriage of the vehicle, and a hydraulic cylinder raises and lowers the vehicle on the lift. Arms are pivotally attached to opposite sides of the lift with a wheel at the end thereof for manual movement between a wheel-retracted position and a wheel-extended position. The wheels remain in the extended position by an over-center pivoting design. Two towing mechanisms are provided for moving the lift: a towing bar that can be attached to a towing bracket on an end of the lift, or a wheeled towing dolly having a clevis and securing pin for attachment to the towing bracket. The lift has a safety locking mechanism for securing the lift in various raised positions.

Abstract: The present invention consists of a collapsible hollow core, having a circumferentially variable wall thickness, for use in a method of forming a hollow article. The core is manufactured by extruding a hollow parison into an open core forming mould, closing this mould, expanding the parison against the inner walls of the core forming mould by injecting pressure into the parison, and opening the mould to remove the core. The core thus formed is used in a method of forming a hollow article of a resin reinforced with fibers. The method consists of winding reinforcing fibers tightly around a hollow core having a circumferentially variable wall thickness and placing the wound core in a mould. A differential pressure is then provided between the interior and exterior of the core to cause a thinner wall portion thereof to initiate collapse of the core, and this collapse is continued to an extent necessary to relax the fibers.
