Title: Self-contained cooling device for food containers
Inventor: HOLCOMB ROBERT R
IPC: B65D81/32
Filed: 1987-07-02
Granted: 1992-03-03
Abstract: ABSTRACT   A self-contained cooling device for use in a container such as a food container to cool the contents of the container at any desired time includes a reservoir containing pressurized fluid. The reservoir is secured to the inside of the container to form an expansion chamber between the reservoir and the container. A tube communicates with the reservoir and extends into the expansion chamber, the tube normally being closed to prevent escape of pressurized fluid from the reservoir. When it is desired to cool the contents of the container the tube is opened so that pressurized fluid from the reservoir expands into the expansion chamber thereby cooling the expansion chamber, reservoir, and contents of the container. Embodiments of the device shown specifically are adapted to be used with commonly used "pop-top" beverage cans and in such instance the tube extends to securement with the tab used to operate the "pop-top" or with a separate tab, and operation of the tab causes opening of the tube in the expansion chamber. The device may be secured to the end of the normal "pop-top" can and the reservoir is generally conical in configuration, so can easily be inserted into the filled beverage can by high speed canning equipment as the end is placed on the can and sealed. A further embodiment of the device is shown specifically adapted for use and resue in an insulated food containter.

Abstract: DESCRIPTIVE ABSTRACT            Nuclear reactor control process.            It consists of determining by an iterative calculation the neutron flux ?(j,g) at each point j of the core in the form of a sum of two components, the first component being associated with a pre-determined state of the core defined by predetermined interaction probabilities of the neutrons in the core and the second component being linked with the real state of the core, with said predeter-mined state and with said first component.  The power given off P(j) and the number of emitted neutrons S(j) at each point of the core are then deduced from the neutron flux.  The power given off P(j) and the neutron flux ?(j,g) are used for controlling the core regulating means, such as the control rods or the boron concen-tration.            (no drawing)

Granted: 1992-03-17
Abstract: ABSTRACT           This invention relates to abrasive grains, and, more particularly, abrasive grains having a particular shape and side.          Three basic technologies that can be employed in the production of shaped abrasive materials suitable for use as abrasive grains are fusion, sintering, and chemical ceramic.  However, it is not known whether any particular shape or size of abrasive grains would provide enhanced properties with respect to abrading.          This invention provides abrasive grains having a shape such that the mean particle volume ratio thereof is less than about 0.8, and preferably ranges from about 0.3 to about 0.7.  Typically, the grains have the shape of a thin platelet, the average thickness of which must be no greater than about 460 micrometers.          The abrasive grains of this invention can be used in coated abrasive products, bonded abrasive products, nonwoven abrasive products, and abrasive brushes.          The products made with the grains of this invention exhibit higher initial cut and higher total cut, along with lower grinding forces than do products having equivalent weight loadings of conventional abrasive grains.

Abstract: Abstract Apparatus and Method for Fabricating Wood Trusses An apparatus and method for fabricating wood trusses. The truss members and connector plates are assembled on a conveyor surface, which transports the truss members to a first  pressing  station  where  the  connector  plates  are partially embedded into the truss members and then to a second pressing station where camber is imparted to the truss and  the  connector  plates  are  substantially  completely embedded  into  the  truss.    The  pressing  rollers  have substantially the same diameter and are sufficiently large to prevent the connector plates from rocking back and forth during the initial stages of the pressing operation.  Three elongated guide rails are  disposed  beneath  the conveyor surface to prevent the sagging thereof under the weight of the truss.   The two outer guide rails extend all the way through the first pressing station to keep the conveyor surface in proper alignment.  Camber is imparted to the truss in the second pressing station by means of two sets of oppositely positioned camber rollers.   The first pair of camber rollers is mounted on a pivot arm for contacting the top chord of the truss and the second pair of camber rollers is adjustable by a single adjustment mechanism, laterally with  respect  to  the  axis  movement  of  the  truss,  for contacting the bottom chord of the truss.   An adjustable stabilizer bolt contacts the pivot arm to prevent free play therein during the cambering operation.   In an alternate embodiment camber is imparted to the truss on the conveyor surface before the connector plates are attached by placing the truss members between a plurality  of tooling blocks disposed at predetermined fixed positions on the conveyor surface in accordance with the truss dimensions and desired amount of camber.
