Abstract: Raccoon poxvirus, an organism that may be indigenous in nature, is established as a suitable substrate for insertion and expression of nucleotide coding sequence of heterolgous organisms. Two infectious raccoon poxvirus recombinants for expressing rabies virus surface spike glycoprotein (G) were produced by homologous recombination between raccoon poxvirus DNA and chimeric plasmids previously used for production of vaccinia virus recombinants by thymidine kinase insertional inactivation. Raccoons that were fed polyurethane baits loaded with raccoon poxvirus recombinant quickly developed high levels of rabies virus neutralizing antibodies and were protected when challenged with an otherwise lethal dose of raccoon rabies street virus. Dogs developed rabies virus neutralizing antibodies after feeding a vectored raccoon poxvirus recombinant in contrast to feeding a vaccinia: G recombinant that induced no rabies neutralizing antibodies. Cotton rats, skunks, mice and rabbits that were fed recombinant raccoon poxvirus developed variable levels of rabies neutralizing antibodies. All vaccinated cotton rats were protected from otherwise lethal rabies challenge.

Title: Procedure and apparatus for the sorting of wood chips
Inventor: SEPLING MATTI
IPC: D21B1/02
Filed: 1989-06-08
Granted: 1995-07-04
Abstract: A two-stage procedure is disclosed for sorting wood chips.   The chips are directed to a gyratory screen in the first stage and to a disc screen in the second stage.   The chip flow is divided in the first stage into four fractions of which the first fraction contains mainly oversized chips and is directed to a pin chipper, from which it emerges as suitable-sized chips and is directed back to the gyratory screen of the first stage.   The second fraction contains acceptable sized chips and most of the overthick chips and is directed to the second or thickness screening stage.   The third fraction consists mainly of acceptable chips and is directed to a pulping process, while the fourth fraction consists mainly of fine particles and is directed to a burning station.   In the second or thickness screening stage the chip flow is divided into two fractions of which the rougher fraction comprises overthick chips and is directed via a rock and metal separating device into a slicing machine and then back to the first stage gyratory screen, while the finer fraction comprises acceptable chips and is passed directly to the pulping process.

Abstract: A cooling abnormality detection system for electronic equipment  cooled by a separate cooling device  includes  a protection unit, and also includes a flowmeter, a water gauge, a pump operation detector, and an abnormal temperature sensor in a liquid coolant flow path between the electronic equipment and the cooling device.  The flowmeter detects a decrease in flow rate of the liquid coolant downstream of the electronic equipment.  The water gauge is arranged in a coolant tank in the flow path, and detects a decrease in the water level of the liquid coolant in that tank.  The pump operation detector is connected to  a pump on the  coolant  flow path to detect operation of the pump.  The abnormal temperature sensor detects an abnormal temperature of the electronic equipment.   The protection unit determines that a cooling abnormality exists if an abnormal temperature is detected by the temperature sensor during operation of the pump, or if an abnormality is detected by any one of the flowmeter, the water gauge, and the abnormal temperature sensor during non-operation of the pump.

Abstract: A method of electrophotographically manufacturing a luminescent screen assembly on a substrate of a CRT includes the steps of coating the substrate with a conductive layer and overcoating the conductive layer with a photoconductive layer, establishing an electrostatic charge on the photoconductive layer, and exposing selected areas of the photoconductive layer to visible light to affect the charge thereon. Then, the selected areas of the photoconductive layer are developed pith triboelectrically charged, dry-powdered, surface-treated screen structure materials. The improved method increases the adherence of the surface-treated materials to the photoconductive layer by contacting the surface-treated materials pith a solvent to render the photoconductive layer and the materials tacky. The dried screen is fixed with a plurality of coatings of an aqueous alcohol mixture of dichromated polyvinyl alcohol or potassium silicate and then filmed, aluminised and baked to form the screen assembly.

Abstract: Abstract of the Disclosure A technique for permanently joining thermoplastic parts in a single stroke converts kinetic energy into thermal energy. In this technique, one of the thermoplastic parts includes a linear shaft while the other includes a cavity having the same general shape but being slightly smaller in its cross-section. The thermoplastic parts are permanently joined when the shaft is thrust into the cavity at a velocity that exceeds a predetermined minimum value which is a function of thethermoplastic materials used and the relative dimensions of the shaft and cavity. An interference fit between the shaft and cavity causes frictional heat to be generated which melts the contacting surfaces and thus welds the parts together after a brief cooling period.
