Abstract: CAN. C-1926(ER) HYBRID DUAL VOLTAGE TRANSMISSION SYSTEM            ABSTRACT OF THE DISCLOSURE     A high power high voltage transmission system con-sists of three high voltage cables which are suspended from a transmission tower in insulated relationship with one another and with respect to the ground.  Each of the cables is shown as a gas-insulated cable having a central high voltage conduc-tor and an outer conductive housing which is insulated from the central conductor.  The line-to-line voltage of the cen-tral conductors of each of the high voltage cables is 765 kV, while the potential between the outer conductive housings of each of the cables is 345 kV.  The total right of way and height of the support tower is that needed for a conventional 345 kV transmission system even though the system is used to transmit 765 kV line-to-line voltage.

Title: Method and means for replicating centrally  apertured video disc records
Inventor: HOLMES JOHN R
IPC: B29D17/00
Filed: 1980-10-23
Granted: 1982-06-01
Abstract: ABSTRACT           This invention relates generally to a method and apparatus for molding a centrally apertured part, such as a video disc.  Prior art molding techniques are deficient in that extremely tight hole centering tolerances could not be met, and likewise thickness tolerance caused excessive birefringence of a light beam used in reading the disc.  The present invention overcomes these deficiencies by providing an improved molding technology.  In accordance with the invention, heated material is injected into an annular cavity, defined by a pair of mold halves, through a sprue passage, defined by a sprue bushing and an end  portion of a punch.  The annular cavity and the sprue passage form, respectively, the centrally apertured part and a sprue.  After partial cooling of the heated material, the punch is locked in place while the annular cavity is displaced relative to the sprue passage so that the sprue is severed from the part along the peripheral surface of the punch end portion.  The mold halves are separated to open the annular cavity while the sprue is resting on the punch end portion, and while the part is held by the punch end peripheral surface. After the mold halves are separated, a sprue ejector member is actuated to eject the sprue from the punch end portion.  The finished video disc is then removed, carried by the moving platen of the moving mold assem-bly.  An improved injection gate is also provided, as well as a unique manner of cooling the mold assembly.

Abstract: APPARATUS FOR REMOVING CONTAMINANTS PROM CRANKCASE EMISSIONS                  ABSTRACT OF THE DISCLOSURE Apparatus for receiving crankcase emissions from an internal combustion engine and for separating the liquid and solid portions of the emissions from the gaseous portion thereof.  The apparatus includes a container or vessel having an open top which is closed by a cap. The cap has an inlet port for receiving crankcase emissions, an outlet port for permitting the separated gaseous portion of the emissions to be directed through a PVC valve to the intake manifold of the engine, and an air inlet port for allowing ambient air to mix with the crankcase emissions as they are directed toward the interior of the container.  The cap carries a porous body which separates the incoming crankcase emissions flowing between the inlet port and outlet port into the liquid, solid and gaseous portions, the liquid and solid portions being trapped in the container while the gaseous portion is permit-ted to flow toward the outlet port for exit from the con-tainer.  The vacuum produced in the intake manifold when the engine is operating causes a vacuum in the container which, in turn, causes the crankcase emissions to be drawn into the container.  Also, this vacuum unseats a valve in the air intake port against the bias force of a spring to allow ambient air to enter the container and mix with the incoming crankcase emissions and thereby increase the air content of the gaseous portion.  When the engine is not operating, the vacuum is no longer present in the container and the valve in the intake port closes by virtue of the bias force of the spring.

Abstract: S P E C I F I C A T I O N            MAGNETIC SAFETY INTERLOCK METHOD AND APPARATUS FOR FOOD PROCESSOR                   Inventors: Carl G. Sontheimer Allen F. Podell ABSTRACT OF THE DISCLOSURE             Safety interlock method and apparatus employing magnetic effects for a food processor of the type having a base housing enclosing a motor drive, a working bowl which is detachably mountable on the base housing in position for re-ceiving various rotatable food processing tools which are removably installed on a tool drive in the bowl, with a re-movable cover on the bowl.  Food processors of this type normally include a hopper or feed tube which is carried by the cover, and a manually operated pusher or plunger which is used to feed food items down through the hopper onto the rotating cutter blade, slicing disc, rasping tool, etc.  The safety interlock in one of its embodiments prevents actuation of the relatively powerful motor drive, so that the food proces-sing tool does not rotate unless two conditions have been met, namely, (1) unless the working bowl is mounted in proper posi-tion on the base housing, and (2) the cover is held in proper position on the bowl.  The cover thereby prevents the user from inadvertently inserting a hand down into the working bowl.          This safety interlock in another of its embodiments prevents actuation of the motor drive unless three conditions have been met, namely, (1) bowl in proper place on the base housing, (2) cover in position on the bowl, and (3) the food pusher is inserted into the feed tube in the cover.   In the case of a relatively large feed tube, the user is prevented from inad-vertently inserting a hand or foreign object down the feed tube by the food pusher where there is risk of encountering injury from a rotating tool in the bowl.  By virtue of this latter interlock, the feed tube can safely be made to have a larger cross-sectional area so that larger food items can be inserted whole into the food processor.   Moreover, the entire size of the working bowl, cover and feed tube can be proportionately enlarged for providing a larger overall machine.   The various interlock systems employ magnetic effects advantageously in ways for increasing their discrimination against inadvertent actuation by ordinary magnets.

C'est-à-dire que les tests conçus pour mesurer la précision des lancers de la bouée de sauvetage repose presque exclusivement sur des échelles de valeurs mentales telles que perçues et interprétées par l'enseignant. Pour faciliter la mesure et pour la rendre plus objective et plus fidèle, une cible de lancer fut construite. La cible pour le lancer de précision de la bouée de sauvetage constitue un instrument pour mesurer l'habileté de lancer avec précision la bouée de sauvetage. Elle est construite de tuyaux en aluminium, ou en toute autre matière convenable, de sorte que celle-ci flotte à la surface de l'eau et maintienne sa forme. La cible et ses parties sont maintenues en place sur l'eau par un système de crochets et de cordes. Les tuyaux formant la cible délimitent différentes zones de précision. Ces zones de la cible sont conçues pour mettre en valeur les critères de précision utiles au lancer de la bouée de sauvetage.
