Title: Coanda effect gene delivery instrument and method of use
Inventor: SWAIN WILLIAM F
IPC: C12N15/87
Filed: 1996-06-03
Abstract: An apparatus (8) is disclosed for the genetic transformation of organisms by accelerated particle mediated transformation. Foreign genes are introduced into cells by coding on carrier particles (55') which are physically accelerated into the cells by positioning the carrier particles (8) on the external surface of a carrier ribbon (56) which is wound on a cartridge (14), the carrier ribbon (56) having an exposed portion. The carrier particles (55') on the exposed portion of the ribbon (56) are displaced and accelerated toward an exit port (52) by a high pressure stream of helium gas. By rotating the ribbon (56), a continuous supply of carrier particles (8) can be produced and hence large target areas can be transformed without the need to replace the particle carrier. Near the exit port (52), the gaseous stream is diverted through use of the Coanda effect to divert the gas stream away from a target area.

Abstract: This invention is an oversized spinal implant (100) for trans-lateral insertion into the disc space between two vertebrae, a length that is greater than one half of the transverse width of the vertebrae, and is greater than the depth of the vertebrae. The trans-lateral implant of the present invention has a height that is greater than the height of the disc space between two adjacent vertebrae so as to engage both of the vertebrae.  The width of the implant need be only slightly less than the depth of the vertebrae themselves. The trans-lateral spinal fusion implant of the present invention has more surface area of contact, and thus permits greater stability so as to withstand torque, and in the case of a threaded implant, increases the depth in which any threads are able to penetrate the vertebrae.

Title: Improved contact toaster
Inventor: AGCAOILI CLARK R
IPC: A47J37/08
Filed: 1998-01-30
Abstract: An improved contact toaster for heating sandwich buns and other food items features a housing containing a toasting chamber with an inlet and an outlet. The toasting chamber contains a pair of conveyor belts with a heated platen positioned between them. Each conveyor belt features a platen-facing portion so that two pathways are defined. Each conveyor belt also features a heat-disitributing surface. Two auxiliary heaters are positioned so that one of each heats one of each of the platen-facing portions of the conveyor belts. One of each of a pair of tensioners engages one of each of the platen-facing portions of the conveyor belts so that each pathway tapers inward to a minimum thickness and then expands outward again. As a result, food items moving through the pathways via the conveyor belts are toasted on both surfaces and also absorb heat from both the platen and the conveyor belt surfaces in a sponge-like manner as they are compressed and released.
