Title: Method and apparatus for determining resonant frequency of a turbine blade made of a material not responsive to a magnetic field
Inventor: MOORE DONALD W
IPC: G01N29/12
Filed: 1988-09-01
Granted: 1992-01-28
Abstract: - 12 -              53,883 ABSTRACT           A method and apparatus for resonant frequency testing of free standing turbine blades made of a material, such as titanium, that is not responsive to a magnetic field is disclosed. A lightweight shim 12 made of a magnetically responsive material such as steel, weighing on the order of 0.5 grams, is attached to the convex side of the blade 10. The shim 12 is excited by an oscillating magnetic field and moves the blade 10 accordingly. The maximum amplitude of blade 10 movement is recorded and used to determine the resonant frequency as the excitation frequency of the magnetic field is swept through a frequency window range. The low weight of the shim 12 does not materially change the resonant frequencies of the blade 10.

Title: Air nozzle for use in production of nonwoven fabric
Inventor: KOBAYASHI YOSHINORI
IPC: D04H3/03
Filed: 1989-02-01
Granted: 1995-03-14
Abstract: An air nozzle for use in the production of nonwoven fabric that is adapted to receive spun filaments from a spinning nozzle and feed the filaments in an air jet onto a receiver.          The air nozzle is directed to the prevention of any abrasion of the inner surface of the nozzle body by an additive, such as titanium white, contained in filaments, and thus to the prevention of any defects in the nonwoven fabric.  The inner surface of a nozzle body for guiding filaments is formed using a ceramic material to protect that surface.  The nozzle body has a conical passage whose diameter gradually decreases from an inlet for receiving the filaments from the spinning nozzle, and a straight passage continuing from the conical passage and extending with a constant diameter, at least part of the inner surface of the conical passage and/or the straight passage being formed as a ceramic surface.

Title: Paper guide wheel
Inventor: KEMP NORMAN H
IPC: B41F21/10
Filed: 1989-02-02
Granted: 1994-11-15
Abstract: A paper guide wheel for printing presses is formed to include an outer surface eccentric with respect to the axis of rotation of the wheel so as to form an air gap between the outer surface of the wheel and the paper as the paper is drawn thereover during movement through the press. The air gap gradually narrows as the wheel turns, allowing the freshly inked surface of the paper to gently nest against the outer surface at a point removed from the leading edge of the paper. The outer surface has a slightly convex contour in the axial direction to avoid marking of the paper by contact with the axial extremes of the outer surface. Foam material may be provided on the wheel rim to assist in supporting the paper without marking the freshly inked image.

Title: Electronically scored dart game having front opening service door
Inventor: HANSEN NORMAN C
IPC: F41J3/00
Filed: 1989-03-09
Granted: 1992-10-27
Abstract: ABSTRACT An electronically scored dart game includes a service door for providing access to the interior of the game housing from the front of the housing.  The service door is formed of at least a portion of the front housing surface, including the dart board, and has an upper end and a lower end. The service door is hinged to the housing along at least a portion of the lower end.  The service door is pivotable about the hinge for movement between a generally vertical operational position and a service position in which the service door extends outwardly from the front surface of the housing at a predetermined angle of less than 180 degrees.  In the preferred embodiment, the predetermined angle is approximately 90 degrees.  At least one flexible member is provided for preventing the service door from pivoting to a position exceeding the predetermined angle.  When the service door is in the service position, gravity causes movable target plates within the dart board to engage stops within the dart board supporting structure to prevent the target plates from moving out of the supporting structure.

Abstract: DEVICE FOR SHEARING A GROUP OF TUBES      ABSTRACT OF THE DISCLOSURE      A saddle with two cutting stations, i.e., front and rear openings, moves forward and backward horizontally within a chassis.  The rear opening includes a cutting blade.  The chassis includes a front counter blade.  A magazine holds a tube bundle and includes a rear face clamp and rear counter blade.  In a first cutting operation, skirting at the base of the tube bundle is placed in the front opening and is cut by first moving the saddle rearward against the rear face clamp and rear counter-blade, and then frontward against the front counter-blade.  In a second cutting operation, the tube bundle is placed in the rear opening.  As the saddle is moved frontward, the cutting blade in the rear opening cooperates with the front counter-blade on the chassis to cut the tubes.  This second cutting operation is continued until the tubes are cut.

Abstract: Abstract of the Disclosure A semiconductor light detector includes a first semiconductor layer of a first conductivity type having a multi-layer structure including a light absorbing layer and an avalanche multiplicating layer, an annular second semiconductor layer formed on the first semicon-ductor layer, a light detecting region formed by doping an impurity of a second conductivity type in a surface region of the first semiconductor layer, in such a manner that a peripheral portion of the light detecting region is located outside an inner periphery of the second semiconductor layer, the light detecting region defining a first p-n junction in combination with the first semiconductor layer, and a guard ring formed by doping an impurity of the second conductivity type in a surface region of the second semiconductor layer to surround the peripheral portion of the light receiving region with the first semiconductor layer, the second p-n junction having a concentration gradient lower than that of the first p-n junction.  By virtue of the presence of the second semiconductor layer, the junction depth of the peripheral portion of the light detecting region is less than that of the central portion of the light detecting region, and the junction depth of the guard ring is greater than that of the peripheral portion of the light detecting region.  As a result, a sufficient guard ring effect can be obtained without a guard ring having a great junction depth.

Abstract: A meat emulsion containing meat, meat by-products, water and one or more dry proteinaceous materials is prepared, with the emulsion having a protein to fat ratio of at least about 1.5:1 and a moisture content in the range of about 45% to 80%. The hot meat emulsion is introduced by centrifugal force into a confined holding tube in which the emulsion is retained for a relatively short period of time during which the protein coagulates to set the emulsion and provide a firm meat emulsion product, with the emulsion being maintained at a pressure greater than the vapor pressure of emulsion water. When the protein has coagulated sufficiently to form a firm emulsion, the emulsion pressure is reduced below the vapor pressure of the emulsion water so that water in the emulsion is vaporized, and pressurized steam is periodically injected into the emulsion mass. The effect of the combination of pumping the hot emulsion into the holding tube by centrifugal force, subjecting the confined emulsion to steam pressure while the protein is rapidly coagulating, together with pressure exerted on the emulsion, provide a set meat emulsion product having a plurality of distinct emulsion layers which are bonded together, and the layered product is discharged from the holding tube in the form of discrete pieces or chunks. Such layered meat emulsion chunks may be used for human consumption or for consumption by pet animals, depending on the nature and quality of the meat materials used.
