Title: Ultralight microwave antenna and method of fabrication
Inventor: RODRIGUEZ ANGEL E
IPC: H01Q21/06
Filed: 1989-11-21
Abstract: ABSTRACT      An antenna assembly (10) fabricated of lightweight, aluminum alloy foil material which forms individual parts that are laser welded together.  The parts include mating projecting tabs (18) and slots (20) which render the unit self-jigging in assembly and provide added strength in the finally welded unit.  Common tooling pins (not shown) are used to stack the piece parts in proper alignment during assembly by inserting the pins through particular tooling holes (46) in individual parts.  Laser welding is used at various levels of assembly and a base module sub-assembly is initially fabricated, to which additional individual components are affixed and welded in place.  The resulting unit is a precision antenna assembly, light in weight and structurally strong, which can be built with very low fabrication costs.  The microwave aperture features of the unit are developed and located with the feature relation-ship being held to very precise tolerances.

Title: Emergency resumption processing apparatus for an information processing system
Inventor: TAKIDA MASATOSHI
IPC: G06F11/20
Filed: 1990-10-16
Abstract: Abstract of the Disclosure A program pattern writing part established within a central processing unit writes a program pattern that causes a watchdog timer to make an overflow action in the loading area of the emergency resumption processing program on the main memory device.     An emergency resumption processing program loading part established within the same central processing unit reads the emergency resumption processing program from an external memory device after above the writing processing are completed, and loads it on the main memory device by rewriting the program pattern written by the program pattern writing part.     As a result, if a fault arises in the transmission function of the emergency resumption processing program and the central processing unit starts to run the program on the main memory device without the emergency resumption processing program being loaded on the main memory device,  since the program pattern already written in the main memory device by the program pattern writing part is run, the watchdog timer is never reset accidentally and properly detects a system abnormality.
Patent CA-2027912-A1 (CA)
Title: Rotating joint
Inventor: VILLENEUVE MAURICE
IPC: F16L27/08
Filed: 1990-10-18
Abstract: A rotating joint for tiltable metallurgical furnaces includes first and second flanges fixedly secured respectively to a furnace which points about an axis of rotation and to an outlet launder. The adjacent flanges extend radially from the axis of rotation and face each other. The second flange includes a series of equidistant and similar arcuate slots distributed near the periphery thereof about the axis of rotation. A corresponding hole is defined in the first flange for each of the arcuate slots. A tie rod which extends through the first and second flanges and through a seal gasket provided therebetween includes at the end thereof protruding from the stationary second flange a pair of coaxial rollers which are rotatably mounted on a pin fixedly secured to the tie rod in order that the common axis of the rollers is, parallel to a radius of the stationary second flange. The end of the tie rod protruding outwards of the rotating first flange is threaded to receive a nu-t for tightly attaching the two flanges together with the pairs of rollers bearing against the stationary second flange on each side of the arcuate slot. Therefore, upon rotation of the furnace, the first flange rotates thereby causing the tie rods to displace along respective arcuate slots with the rollers rolling on the stationary second flange while keeping a constant pressure on the flanges to maintain the seal. This allows a free motion of the furnace tilt while providing a reliable and durable seal against infiltration and leaking while molten metal flows through the rotating joint.

Title: Two-stroke-cycle engine with variable valve timing
Inventor: RICHESON WILLIAM E
IPC: F02B75/02
Filed: 1990-11-06
Abstract: ABSTRACT OF THE DISCLOSURE   A two-stroke-cycle spark ignited internal combustion engine operates with an exhaust valve that is controlled independently of crankshaft position and optimally for high power and low pollutant output in combination with a scavenging pump and fuel injector. The volume of combustible mixture is established at the point in the cycle when the exhaust valve is selectably closed with the piston traveling upwardly and decreasing the volume of the cylinder. Throttling losses are eliminated since the piston forces the scavenging air out of the cylinder through the wide-open exhaust valve rather than the air being drawn into the cylinder against the reduced pressure caused by a conventional partially closed throttle plate. The volume of combustible air in the cylinder is determined by the point in the cycle at which the exhaust valve is closed and a correspondingly appropriate charge of fuel is thereafter injected into the cylinder.

Title: Self-aligned gate process for fabricating field emitter arrays
IPC: H01J9/02
Filed: 1990-04-23
Abstract: SELF-ALIGNED GATE PROCESS FOR FABRICATING           FIELD EMITTER ARRAYS                            ABSTRACT Conical field emitter elements are formed on a surface of a substrate after which a layer of metal is deposited on top of the substrate surface and over the field emitter elements.  A layer of oxide is then deposited over the metal layer.  Another layer of metal is deposited over the layer of oxide to form a gate metal layer.  A layer of photoresist is then deposited over the gate metal layer.  The layer of photoresist is then plasma etched in an oxygen atmosphere to cause portions of the photoresist above respective field emitter elements to be removed and provide self-aligned holes in the photoresist over each of the field emitter elements.  The size of the holes may be controlled by appropriately controlling process parameter, including plasma etching time and power and/or initial photoresist thickness.  The exposed gate metal layer is etched using the layer of photoresist as a mask. The photoresist layer is removed, and the layer of oxide is etched to expose the field emitter elements.  Another oxide layer and an anode metal layer also may be formed over the gate metal layer to produce a self-aligned triode structure.

Abstract: Abstract The first automatic valve (66) of a safeguard (36) is connected in the flow path (60) of a sanitary fitting. The diaphragm (122), as the valve body (90) of the second valve (68) interacts with the valve seat (72) and the first valve (66) is arranged on said diaphragm. Under normal operating conditions, the second valve (68) is closed and the first valve  (66)  is opened.  Under conditions allowing backflow counter to the direction of the arrow S, the first valve (66) closes automatically, by which means the diaphragm (122) is deformed counter to the direction of the arrow S due to the suction on the input side, which results in the second valve (68) being inevitably opened. By this means, water is prevented from flowing back into the feedline and the outlet is con-nected to the ambient air through the opened second valve (68) and the aeration path (58).
