Hybridoma cell lines and antibodies that bind to the dorsal growth inducing factor noggin, having the amino acid sequence set forth in SEQ ID NO:2, are also described.

Abstract: A centralizer 10 for positioning against a prosthetic implant 1. The centralizer 10 includes a plurality of inner raised ribs 15 extending from the inner surface 13 of the centralizer 10. The inner ribs 15 provide inner recessed pathways 16 which extend from the distal edge 12 toward the proximal edge 11. The centralizer 10 also may include a plurality of outer raised ribs 17. The inner and outer ribs 15 and 17 space the centralizer 10 from the implant 1 and the bone 5. This allows bone cement to flow into the gaps created between centralizer and the implant and between the centralizer and the bone.

Abstract: This invention increases the flow of breathable air from an air pump to an enclosure such as a hood or enclosed structure without requiring an increase in the air pump output. The invention involves interposing an jet venturi induction pump in the conduit between the air pump and the enclosure. Breathable filtered, muffled, and metered ambient air is induced into the jet venturi induction pump, thereby increasing the flow of breathable air into the enclosure without an increase in the air pump output. In addition, the jet venturi induction pump cools and reduces the humidity of the air emitted from the air pump.

Abstract: An apparatus is disclosed which uses a high volume low pressure air curtain in an "air chisel" to inhibit and reduce the bounceback and overspray of material sprayed on a work surface. The air chisel directs a lateral air curtain along each side of a plume of sprayed material parallel to the long axis of the plume and directed toward the contact of plume and work surface. An air chisel may be attached to a spray gun or may be mounted on a stand adjacent to the work surface. Any source of high volume low pressure air may serve to provide air to an air chisel.

Abstract: A novel and soluble polypeptide that is highly conserved among vertebrates has been discovered, which is designated "noggin." The properties of noggin include dorsal growth inducing activity. Noggin and activin act synergistically to produce dorsal mesoderm. Noggin's cDNA has been cloned. Several expression systems have been successfully used to express biologically active noggin. Amino acid sequences representing completely conserved portions as between frog noggin and mouse noggin are:QMWLWSQTFCPVLY (SEQ ID NO:3);RFWPRYVKVGSC (SEQ ID NO:4);SKRSCSVPEGMVCK (SEQ ID NO:5);LRWRCQRR (SEQ ID NO:6); and,ISECKCSC (SEQ ID NO:7).

Abstract: Frequent cleaning, maintenance, and or replacement of spray guns is necessary for good performance, but cleaning is often neglected because of difficulty in reaching the crucial parts to be cleaned. The spray gun of this invention has a fluid flow assembly which may be readily removed to facilitate cleaning. In addition, this spray gun has an external fluid flow assembly packing gland adjustment nut, which allows frequent convenient adjustment of the packing gland without disassembly of the spray gun. This allows the user to maintain free movement of the needle valve shaft while preventing leakage of fluid into the spray gun body.

Abstract: An electronic checkbook (10) is provided for printing checks. electronic checkbook (10) is of a hand-held size and operates on two AAA batteries. An on/off switch (30) which includes a needle valve (410) controls ink flow. A print cap switch (26) is also provided for rugged applications. Checks are advanced under a printhead (38). The printhead (38) and a roller shaft (46) for advancing the checks are both driven by a single motor (56). A transmission (54) translates power from the motor (56) to the printhead (38) and the roller shaft (46). The position of both the motor (56) and the printhead (38) are sensed by use of a single LED (124) and photodetector (128). Ink is supplied to the printhead (38) from an ink cartridge (12). Data is stored in a non-volatile check register (16). Reconciliation of transactional information can be made by reference to information stored on a statement strip (20).

Abstract: A coal-fired gas turbine engine is provided with an on-site coal preparation and engine feeding arrangement. With this arrangement, relatively large dry particles of coal from an on-site coal supply are micro-pulverized and the resulting dry, micron-sized, coal particulates are conveyed by steam or air into the combustion chamber of the engine. Thermal energy introduced into the coal particulates during the micro-pulverizing step is substantially recovered since the so-heated coal particulates are fed directly from the micro-pulverizer into the combustion chamber.

Abstract: This invention reduces the air pollution associated with spraying of paints, coatings, solvents or pesticides against a surface. Spraying invariable causes bounceback of sprayed solids as well as overspray consisting of bounceback and an aerosol of solids, solvent, and air and is an important source of air pollution. This invention is a resprayer consisting of a jet venturi induction pump located near the front of a spray gun which captures the overspray and a respray nozzle which redeposits the captured material on the work surface.

Abstract: A process of applying a finish to an electrically conductive vehicle body by passing the body through a water-based electrocoating bath while applying a voltage between the body and the bath to electro-coat the body with constituents of the bath. The coat is dehydrated to a state of sufficient dryness to permit spray application of a water-base primer while maintaining the coat cool enough to avoid fusing the coat. A coating of water-base primer is then sprayed over the dehydrated but otherwise untreated E coat. The coat and coating are then baked to concurrently fuse both of them. The primer sprayed on an interior portion of the body is pigmented to a desired finished color. Selected portions of the baked coating on the exterior of the body are light sanded to remove entrained dirt and thereafter finish coating is applied to the body.

Abstract: An spray gun extension used in the application of liquids such as paints and other coatings, cleaning solutions, solvents, blasting agents, solvents, sealants, lubricants and pesticides in high volume low pressure spraying. The extension allow the application of such liquids to areas above, below, around, behind, or into devices or fixtures not visible and otherwise inaccessible to the applicator. The extension is rotatively mounted to the spray gun. A spray head is rotatively mounted on the extension. A variety of spray nozzles may be used, including a fixed nozzle, and a nozzle which may be used to vary the spray pattern width and fan shape. Liquid flow is controlled by a needle valve near the end of the extension. The extension may be used to spray straight ahead or at any angle including back toward the spray gun.

Abstract: A high volume, low pressure air system for atomizing a fluid, such as paint, includes, among other things, a variable jet venturi induction pump which generates low pressure air for powering one or more atomizing devices, such as spray guns, with the intake of the induction pump being located a predetermined distance away from the atomizing devices so that overspray produced thereby is prevented from being fed along with ambient air into the induction pump. The system also controls the supply of compressed air and can be equipped with a compressed air driven intake fan for turbo charging the ambient air fed to the jet venturi induction pump. A booster source of regulated low pressure air is also coupled to the feedline(s) coupled to the individual atomizing devices to augment the low pressure air generated by the jet venturi induction pump for certain spraying tasks.

Abstract: A coupon dispensing system which displays a number of images, each image representing a product to be promoted and including a product selection area to be manipulated by a consumer to select that product. A switch is associated with each selection area to register the selection. The system receives an access code unique to the consumer, records product selections made by the consumer, compares the product selected by the consumer with a preselected quota, and issues a coupon for the product selected by the consumer if the quota for that consumer is not exceeded.
