Abstract: An improved golf teeing apparatus adapted to automatically tee a predetermined number of golf balls in time sequences selected by the golfing participant. The apparatus comprises a housing having a ball inlet opening in a side portion thereof, a housing cover assembly having a tee access opening therein, and a ball hopper connected to the housing via a ball delivery conduit such that gravitational single file ball travel is achieved through the ball delivery conduit to the ball inlet opening of the housing. A ball support assembly is disposed within the housing for receiving one ball at a time from the ball delivery conduit, and for supporting the golf ball at a selected height above the housing cover so that the golf ball can be struck by a golf club. The ball support assembly includes a vertically disposed tubular member having a ball receiving opening communicating with the ball inlet opening of the housing, and a piston member disposed within the tubular member.

Abstract: An apparatus and method of use is provided for the fusion of different cell types into hybrid cells through the use of electrofusion. The apparatus consists of thin-film electrodes etched onto an optically clear lower plate, a channel defined at its boundaries by a photocopolymer material laminated between the lower plate and an upper optically clear top plate providing closure of the channel as well as entry for the cells through the use of integral Luer ports. The apparatus may be produced, with minor adjustment, by using phototools.

Abstract: The interferometer makes use of an acousto-optic device to perform a frequency shift of the beam sent along one of the interferometer branches, so as to allow the determination of the state of polarization by heterodyne radiofrequency detection. The acousto-optic device can be inserted downstream of the device for splitting the beam emitted by the source into the two beams sent along the two interferometer branches, or it can also act as the beam splitter.

Abstract: A polymerizable composition comprised of a major amount of a polymerizable component and a minor amount of a multi-ethylenic glycoside compound (e.g. acrylate and/or methacrylate esters of an alkyl glucoside or allyl ethers of an alkyl glucoside) useful in forming a crosslinked polymeric composition. Novel multi-ethylenic alkyl glucosides are disclosed which are prepared by a novel method. The polymerizable compositions are useful as castings, moldings, extrusions, coatings, binders and adhesives. The multi-ethylenic alkyl glucoside monomers yield crosslinked polymeric compositions having properties which are generally comparable, or superior, to compositions based on commercially available multi-ethylenic monomers.

Abstract: A padlock type security seal and method of making same including a U-shaped shackle, a pair of reversely bent end portions, and a body portion having a pair of chambers for receiving the bent end portions. The chambers each have a locking groove therein for receiving the bent end portions. The seal elements are designed from two molded pieces, an insert and a body. The relative dimensions of the chambers, the shackle, and the locking grooves are chosen to prevent picking.

Abstract: To assist electric submersible pumps in producing highly viscous crudes from oil wells, injection water is conveyed to the pump assembly, injected into the crude, and mixed with it to form an oil-in-water emulsion. This effectively decreases the viscosity of the produced fluid and helps to control pump operating temperatures. The water injection is done in a shroud at the base of the submersible pump.

Abstract: A solvent-based thermosetting coating composition comprising a hydroxy functional urethane modified polyester resin and blocked polyisocyanate crosslinking agent. The coating composition may be formulated as a hot sprayable, high solids coating composition suitable for use as chip resistant automotive vehicle primer suitable for use on body panel areas subject to chipping by stones, gravel and other road debris. Alternatively, the composition may be formulated as a high solids composition sprayable with conventional spraying equipment. The hydroxy functional urethane modified polyester resin is the produce of polymerization of lactone monomers in the presence of hydroxy-containing urethane modified polyester precursor. The polymerization reaction mixture comprises between about 10 and about 80 weight percent the hydroxy-containing urethane modified polyester precursor and between about 90 and about 20 weight percent lactone monomers.
