Title: Flow imaging cytometer
Inventor: OGINO SHINICHI
IPC: G01N15/14
Filed: 1991-09-05
Abstract: FLOW IMAGING CYTOMETER ABSTRACT OF THE DISCLOSURE:       A flow imaging cytometer, in which an image capturing area for cells traveling in the flow of a specimen solution is constantly monitored to perform cell photography in an efficient manner, is improved so that fluorescent images of cells can be acquired with greater efficiency.  Cell particles to be sensed in the specimen are treated with a fluorescent stain, and the specimen solution is irradiated with light from a pulsed light source for exciting fluores-cence, and with infrared light constantly for monitoring the passage of cells through the cytometer.  When the monitoring light is made to serve also as the light for exciting fluorescence, the specimen flow is continuously irradiated at all times at a low luminance for the purpose of monitoring.  Then, when a cell particle of interest is detected, the cell particle is irradiated with a light pulse of high luminance to obtain a still picture of the fluorescence-emitting cell.  At detection of the cell, a source of white light can be actuated to acquire a white-light image of the cell.

Title: Method for extending the holding time for cooked food
Inventor: ASH DENNIS G
IPC: A23L13/70
Filed: 1991-09-18
Abstract: ABSTRACT OF THE DISCLOSURE A method of extending the holding time for a cooked food under specified conditions of temperature and high relative humidity, and more specifically, a method of significantly extending the holding time for cooked chicken products for an additional period through controlling of the environment or atmosphere within a holding chamber without encountering any appreciable loss in the organoleptic, olfactory or textured qualities of the food.  The chicken product is maintained in a holding chamber in an environment or atmosphere at carefully controlled dry bulb and wet bulb temperatures under conditions of a high relative humidity. This high relative humidity in the environment within the holding chamber, which is a result of the high partial pressure of water vapor, will prevent any migration or diffusion of water vapor or flavor components from the cooked chicken product to the surroundings, which would cause a degradation in the organoleptic and olfactory properties of the chicken product, and cause the latter to lose its "fresh" taste and attractive appearance to a consumer.  The food may also be treated with tocopherol prior to cooking so as to retard and reduce lipid oxidation and development of warmed-over flavor during an extended holding time in the holding chamber subsequent to cooking of the food.

Abstract: ABSTRACT OF THE DISCLOSURE     A swivel for use in conjunction with directional drilling consisting of a first tubular housing and a second tubular housing positioned in end to end relation with the first tubular housing.  The first tubular housing and second tubular housing are maintained in axial alignment while permitting relative rotation. An axial bore has a first portion extending through  the  first  tubular  housing  and  a  second  portion extending through the second tubular housing.   The first portion has two axial grooves and the second portion has an inwardly projecting tongue.  A tubular screw having exterior threads is rotatably mounted within the axial bore.  A member is disposed within the axial bore.  The member has a first end, a second end,  and thread engaging means for engaging the exterior threads of the tubular screw.   The member has two radial tongues adjacent the first end which mate with the axial grooves in the first portion of the axial bore such that the member moves  axially along the  first tubular housing  in response to rotation of the tubular screw.  The member has a spiral-form groove which extends between the first end and the second end and which mates with the inwardly projecting tongue in the second portion of the axial bore.  In response to axial movement of the member the radial tongue travels along the spiral path provided by the spiral groove thereby incrementally rotating the second tubular housing relative to the first tubular housing.

Title: Surfacing hardening for seal rings
Inventor: EVENSON ROBERT E
IPC: F16J15/16
Filed: 1992-04-03
Abstract: Surface Hardening For Seal Rings ABSTRACT OF THE INVENTION Rotary fluid machines are generally comprised of a housing and a rotor assembly.  Fluid seals are commonly used to restrict the flow of fluid out of the machine housing to fit the point where the rotor assembly passes through the housing.  The fluid seals often contain relatively rotating annular seal rings which cooperate to form a fluid seal.  To provide for long life and reliable operation, the sealing surface of the seal rings must be relatively hard.  This invention is a means of providing an annular seal ring with a hard sealing surface without the  use a coating or use of a brittle seal ring material.
