Abstract: METHOD FOR REDUCING DYNAMIC OVERVOLTAGES      IN AN ALTERNATING-CURRENT SYSTEM                 Abstract of the Disclosure A method for reducing dynamic overvoltage in an a-c system which is effectively connected to a converter having an intermediate d-c circuit, par-ticularly for the transmission of high voltage direct current.  At least one short circuit device can be switched on and off between at least one static con-verter, operated as a rectifier and at least one static converter operated as an inverter of the converter. The short circuit device is switched off or open in the undisturbed condition of the converter.  The firing angle of at least one static converter, remaining in operation, is initially adjusted to approximately 90° in dependence on the case of a disturbance as a result of which one of the static converters is no longer controllable.  A short circuit signal, for short-circuiting the static converter which is no longer controllable, is transmitted to the short-circuited converter.  The method is characterized in that the firing angle of at least one static con-verter remaining in operation, is regulated in depen-dence on the alternating voltage of the a-c system connected to this static converter, and in such a manner that an overvoltage of this alternating voltage is reduced.

Abstract: Abstract of the Disclosure The present invention provides an improved cooling system for a reciprocating piston engine.  The engine is of the type having at least one cylinder and a piston movable between a top dead and bottom dead center.  The cooling system comprises a housing or coolant jacket which encircles the outer end of the cylinder and extends towards the inner end of the cylinder.  The coolant jacket, however, terminates short of the inner end of the piston when the piston is at its top dead position.  A fluid passageway is formed through the housing and has both an inlet and outlet. liquid coolant is supplied under pressure to the inlet port on the housing  The coolant flows through the lower section of the water jacket surrounding the piston area thus achieving uniform adequate cooling of both the combustion chamber and piston.  In addition, an oil nozzle mounted within the engine crankcase directs a jet of oil onto the inner surface of the piston dome for further cooling of piston and subsequently supplements cooling of the cylinder barrel and head.  The oil jet is the primary cooling mechanism for the section of the barrel not enclosed by the water jacket.

Title: Seed meter seed tube
Inventor: OLSON JAY H
IPC: A01C7/04
Filed: 1986-01-30
Granted: 1991-06-25
Abstract: SEED METER SEED TUBE                Abstract of the Disclosure A seed meter for metering individual seeds at a controlled rate into a furrow in the ground over which the seed meter is traveling releases the individual seeds into a hollow, elongated seed tube.  The seed tube is curved along the length thereof in a direction opposite the direction of travel of the seed meter over the ground to release the seeds with a horizontal velocity generally equal and compensate for the motion of the seed opposite that of the seed meter.  This enables each seed to reach the ground with little or no velocity  component in  the horizontal  direction,  thereby miniminzing lateral seed bounce on the ground.  Seed bounce within the seed tube is controlled and minimized by the tube curvature which gradually increases in a downward direction along the length of the seed tube.  The inner front wall of the tube has logarithmic curvature from a generally vertical upper end thereof along an upper portion of the tube and exponential curvature along a lower portion of the tube.  The increasing curvature progressively reduces the angles of incidence of seed impact along the inner front wall until the seed eventually slides along the front wall at the lower end of the seed tube and exits the tube at a uniform, predictable angle.  The controlled minimum seed bounce within the tube provides a generally uniform seed residence time within the tube.

Title: Dielectric coating for recording member
Inventor: KRUM JAMES L
IPC: G03G15/34
Filed: 1986-06-06
Granted: 1991-07-23
Abstract: ABSTRACT          This invention relates to a recording member useful in certain types of electrographic recording processes.       Kotz, U.S. Patent 3,816,840 discloses an electrographic recording process and apparatus in which a dielectric recording member is arranged between two electrodes. Magnetically adhered to one of the electrodes is electronically conductive toner powder. The toner powder provides an electrically conductive path between the electrode to which it is bound and the adjacent surface of the dielectric member. A voltage is applied to the electrodes for a time and of a magnitude sufficient to generate a force pattern on the toner which enables toner deposition on the recording member in accordance with the force pattern. The force pattern is generated directly on the toner rather than on the recording member, which is passive in the operation of the apparatus disclosed in the patent.         For certain purposes in the practice of the recording process disclosed in U.S. Patent No. 3,816,840, it is desirable that charge leakage from the recording member be such that a controlled amount of charge is dissipated from the toner deposited thereon, for example, from electrically charged toner applied uniformly to the recording member from an applicator member. One benefit of such controlled charge leakage is that the recording member can be re-imaged with no observation of a residue of a previous image pattern that will interfere with the new image on the recording member.         The dielectric coating exhibits charge dissipation properties that will allow removal and replacement of toner powder within one operating cycle of the aforementioned recording process, and the surface of the coating is sufficiently durable to allow the recording member to be used repeatedly, e.g., at least about 100,000 cycles, before the conductive substrate needs to be recoated.

Title: Fiber-optic image-carrying device
Inventor: ABELE JOHN E
IPC: G02B23/26
Filed: 1986-10-14
Granted: 1990-10-30
Abstract: FIBER-OPTIC IMAGE-CARRYING DEVICE            Abstract An elongated image-carrying member that enables micro-endoscopy to be practiced using normal-sized catheters, includes a drawn, fused, central multi-fiber micro-unit of about 0.5 mm diameter, having about 2,000 glass fibers in coherent array, with a polymeric coating bonded to its pristine as-drawn outer surface.          This combination achieves sufficient flexibility and optical qualities to enable effective use to provide vision for inspection of small passages and ducts.  Flexible image-carrying members having diameter of 0.5 millimeter or less and catheters of diameter of 3 mm or less incorporating such members and effective working channels are achievable.  For vision in remote areas, the micro-unit is employed with a substantially spherical lens with an ocular system for providing a focus range from less than about 2 mm to infinity and having resolution of detail down to the order of about 0.001 inch.  The micro-optical member may be employ-ed with a handpiece in a vision system, the micro-optical member being joined to the handpiece by a detachable connector having a stepped structure for precise alignment between the handle and the micro-optical member.  By application of a relatively thin coating containing an opaque constituent to the as drawn micro-unit, degradation of the image and avoidance of artifacts caused by wave guiding effect are avoided.  Devices with varying bend radiuses are also shown.

Title: Low temperature extrusion process for quick cooking pasta products
Inventor: WENGER MARC L
IPC: A21C11/16
Filed: 1987-07-21
Granted: 1992-08-04
Abstract: LOW TEMPERATURE EXTRUSION PROCESS        FOR QUICK COOKING PASTA PRODUCTS          Abstract of the Invention Quick cooking pasta products are extruded in a low temperature process by advancing a par-tially pre-cooked mixture of pasta flour and water prepared in a preconditioner along the length of a screw extruder through a cooking zone, then through a venting zone and a forming zone, and finally through an extrusion die to yield an extruded prod-uct.  The mixture has a maximum temperature of 215° F. in the cooking zone in order to substantially eliminate the formation of darkened specks in the final extruded product which would otherwise repre-sent portions of the mixture that are burned during cooking.   Limiting the maximum temperature of the mixture in the extruder also greatly enhances the extruded pasta quality by increasing product resis-tance to overcooking and improving the retention characteristics of the original product integrity. Venting of the gaseous products from the mixture during the time that the latter passes between the cooking zone and the forming zones removes signi-ficant amounts of moisture to enable less shear to be imposed on the mixture during the cooking process and to decrease the time required for rehydration of the extruded products.   A venting device has a rotatable screw for enabling gaseous materials to be discharged  from  the  mixture  while  substantially preventing the escape of the mixture from the ex-truder barrel.

Abstract: "ABSOLUTE CAPACITANCE MANOMETERS"     ABSTRACT     A single fluid-pressure transducer unit, of the type in which sensed electrical capacitance is varied in accordance with electrode deflections induced by pressure changes, is rendered capable of characterizing a wide range of pressures extending from near-vacuum to atmospheric levels, with the aid of a distinctive composite-electrode capsule which interacts uniquely with a conventional type of sheet-metal diaphragm.  While sensing relatively low pressures, the exhibited capacitance of the transducer is essentially that appearing between the diaphragm and a nearby electrode carried by the capsule, but, at or near atmospheric pressure, the diaphragm physically engages and deflects that electrode, which is elastically deformable, causing it to vary a further capacitance appearing between that deformable electrode and a companion stationary electrode which is also part of the capsule.
