Granted: 2004-07-20
Abstract: A method for determining density of a formation. The method includes irradiating the formation with gamma rays having energy consistent with Compton scattering. Gamma rays are measured at axially spaced apart locations. Two of the axially spaced apart locations are at an equal distance and in opposite directions relative to the source of gamma rays. The distance is smaller than the spacing of another one of the spaced apart locations. An apparent density for each spaced apart location is determined from the counts. Differences are calculated in apparent density between each one of the spaced apart locations, and a correction factor is determined for apparent density at each spaced apart location, thereby determining the density of the earth formation. In a preferred embodiment, determining correction factors is performed by a neural network using the differences in apparent density as an input vector.

Title: Improved simulated egg patty
Inventor: MANDERFELD MICHELLE MROZIK
IPC: A23L15/00
Filed: 1996-01-23
Granted: 1999-06-15
Abstract: Simulated egg patties and simulated egg yolks, and methods of preparing them, are provided. The simulated egg patties and simulated egg yolks have superior mouthfeel and texture characteristics which are similar to a fried egg prepared from a fresh, natural egg. The simulated egg yolks are prepared by freezing a predetermined amount of egg yolk in a predetermined shape whereby the egg yolk structure is modified so that, upon thawing, the egg yolk is gel-like and essentially maintains its shape. The frozen egg yolk can be combined with, or essentially surrounded with, egg white and then cooked to form a simulated egg patty. Preferably the egg yolk is pre-cooled prior to freezing and the frozen egg yolk is tempered prior to cooking. Upon cooking, the egg yolk portion of the simulated egg patty or the simulated egg yolk has similar mouthfeel and texture to cooked fresh egg yolk.

B/A ? 2    (1) wherein A (mm/s2) is an acceleration which is realized at a time when the compression rate is 75% of a maximum rate in a compression-acceleration region , which region is defined as a period of time from a moment when the compression of the molten thermoplastic resin is started to a moment when the compression rate reaches the maximum rate; and B (mm/s7) is  a deceleration which is realized at a time when the compression rate is 75% of the maximum rate in a compression-deceleration region, which region is defined as a period of time from a moment when the compression rate reaches the maximum rate to a moment when the closing of the molds is completed.  By this method, a molded article having excellent surface appearance free from unevenness of gloss and surface irregularity can be obtained.

Title: Injection molding nozzle assembly
Inventor: KALEMBA JACEK
IPC: B29C45/27
Filed: 1998-06-11
Granted: 2001-09-11
Abstract: A nozzle assembly for use in injection molding comprises a pair of spacers acting between the manifold and either a cover plate or a hot runner plate of an injection molding machine to apply a contact pressure between the nozzle body melt channel and the manifold melt channel to achieve a seal therebetween. The resilience of the spacers result in an increased operational temperature range for the nozzle assembly, the contact pressure being generated and/or maintained over the range of the operational temperatures. An additional advantage is provided in that the nozzle assembly is compact and can be closely spaced with similar nozzle assemblies to achieve center spacings as small as eight millimeters. The assemblies can be mounted and/or removed from the cavity of the manifold plate, and/or changing of the nozzle heater elements, without requiring removal of the mold from the injection mold machine. In one embodiment, the nozzle assemblies can be removed or mounted by removing a cover plate from the manifold plate, the cover plate being capable of retaining multiple nozzle assemblies in place. In another embodiment, the nozzle assembly has a mounting flange and one or more bolts extend through the and engage the manifold plate and these bolts allow mounting and removal of the nozzle assembly.
