Abstract: In accordance with preferred embodiments of the invention a timing adjustment device includes a cam follower that is engaged between an overhead cam and an injector rocker arm, and is mounted on a rotatable eccentric shaft. The geometry of the eccentric shaft and cam follower is designed so that, as timing is varied by rotation of the eccentric shaft, no change is produced in the vertical height of the rocker arm when the cam shaft is on the outer base circle and the injector is bottomed, in order to assure that the "mechanical crush" of the PT type injector is constant despite changes in timing. In a first application of the timing arrangement, it is used together with a simple injector, which does not utilize a multi-plunger arrangement to form a hydraulic link, to achieve lower parasitic losses.

Abstract: A high pressure control valve according to the present invention provides effective and predictable control of a timing fluid and injection fuel metering system of an internal combustion engine. The control valve includes an armature that abuts against a majority of the surface of a valve element to help minimize beating problems. In addition, a compliant web means provides a flexing motion when the valve element seats with a valve seat to mitigate problems of seat beating. Furthermore, the present invention reduces the number of parts of the control valve to achieve simplicity in structure and lower costs, including eliminating the need for a valve stop pin.

Abstract: A valve for selectively permitting the flow of fluid therethrough is disclosed including a housing having at least one inlet and at least one outlet, a valve seat provided in the housing about the inlet, a displaceable ball for cooperating with the valve seat for sealing fluidic communication between the inlet and outlet and a ball guide for guiding the ball between a closed position in contact with the valve seat and an open position spaced from the valve seat. The ball guide includes a central bore for reciprocally receiving the ball and a plurality of circumferentially spaced fluid passages in fluid communication with the inlet, the passages extending substantially parallel to a longitudinal extent of the central bore such that a flow of fluid through the inlet is directed radially outwardly from the central bore and into the circumferentially spaced passages when the ball is in the open position.

Abstract: A pirate's trap board game is presented involving a serpentine pathway between the beginning "Empty Treasures" space and the ending "Open Pirate's Treasure" space. The serpentine pathway is divided into a number of spaces depicting treasure commonly found in a pirate's treasure hunt: a gold bar, an emerald, a sapphire, a treasure chest, a diamond and a pirate. A six-sided die is also utilized to move the player's token, with one face of the die depicting one of the above corresponding figures. When a player rolls a treasure chest he also selects a card from a treasure chest which allows him to advance his token according to the instructions on the card. When a player rolls a pirate, he must pick a card from the pirate's trap cave which instructs him to move his token backward. The game ends when one player rolls a treasure chest and is allowed to advance his token to the open pirate's treasure chest at the end of the serpentine pathway.

Abstract: A fuel system for fuel injectors of an internal combustion engine is provided with a hydromechanical timing valve having a valve body assembly with a barrel and plunger arrangement. The plunger is displaceable within the barrel under the counterbalancing forces of rail fuel pressure (load) and one or more timing valve springs. The relative position of the barrel and plunger determines the effective size of the port through which timing fluid can flow. In accordance a first embodiment, the plunger has a tapered head which covers and uncovers ports in the barrel to a greater or lesser extent, thereby creating a variable flow-through cross section. Alternatively, in accordance with other embodiments, the barrel has ports with slot-like orifices of progressively changing widths which coact with a metering groove on the spool to define a variable flow cross section through which the timing fluid must pass.

Abstract: A thermistor chip has an elongated ceramic thermistor body with an outside surface and opposite ends. A dielectric envelope excapsulates the outer surface of the body, and conductive terminal caps are formed on the end of the body. The material of the thermistor is Mn.sub.2 O.sub.3, NiO, Co.sub.3 O.sub.4, Al.sub.2 O.sub.3, CuO, or Fe.sub.2 O.sub.3.

Abstract: A reversed can end ejector system for detecting and ejecting a can end in reverse orientation with respect to a moving stack of otherwise similarly aligned and nested can ends is disclosed. The system utilizes a reversed end extractor bar having a hook formed at a lower end thereof. The bar is supported above the stack with a support frame so that the hook is free to ride on a cylindrical exterior ridged surface of the stack. When a reversely oriented end is encountered, the hook is sized to drop by gravity into the peripheral gap formed between the reversed end and adjacent non-reversed end. The extractor bar is pivotally connected to a mounting bar which is in turn pivotally connected to the support frame whereupon further advancement of a reversed end with the stack during hooked engagement causes the reversed end to be lifted and removed from the stack via controlled rotation of the extractor bar relative to the mounting bar and then both as a unit relative to the suppport frame.

Abstract: A ventilating and impingement air bar assembly for floatingly suspending a running web and comprising a direct impingement air bar for directing air directly against the coated side of the running web, a dilution air bar mounted along each side of the impingement air bar and in parallelism therewith. The dilution air bars have an air nozzle slot directed generally parallel to and along the web and in a direction away from the direct impingement air bar. The dilution air bars also have a coanda corner over which the air from the slot is directed away from the web. An air supply is provided for supplying air selectively to the impingement air bar or to the dilution air bars.

The resistor is made with an intentionally low initial resistance, and is trimmed to a predetermined resistance by removal of a portion of the resistive material between the circuit conductor terminals. A plunge cut made in the resistive material by a trimmer and extending toward the shunt conductor can be used to provide a wide range of change of resistance without excessive increase of the rate of change of resistance as a function of extension of the plunge cut.

Abstract: A coin-queueing head for use in a high-speed coin-sorting and counting apparatus is provided using a spiral coin-processing channel. Coins are fed from a central loading area through an infeed opening into an infeed area having a height permitting unrestricted outward travel of the coins to a peripheral limit having a generally helical shape. The coins are then fed into a coin-processing channel having a first portion for partially separating face-stacked coins. The coins then pass to a second ramped channel portion providing a gradual depessing of the coins and a sudden release into a third channel portion. An inwardly positioned camming lobe and an outwardly positioned expanded area are provided to facilitate lateral separation of the coins upon their release from the second channel portion.

Abstract: The present invention relates to an improved Schottky barrier device wherein the leakage current present in the reverse bias mode attributed to the presence of an electric field at the Schottky barrier (18) is significantly reduced by the inclusion of one or more field shields (22), P.sup.+ -type diffusions located under the metal anode (16) of the Schottky barrier device at the Schottky barrier (18). The P.sup.+ -type field shields, which are disposed in a pattern on the surface of the Schottky barrier, reduce the surface electric field present, thereby significantly reducing the leakage current related thereto.
