Title: Method and apparatus for injection of molding material
Inventor: BROWN ROBERT L
IPC: B29C35/02
Filed: 1992-06-22
Granted: 1995-10-31
Abstract: A  method  and  apparatus  for  injecting  molding material  into a  self-clamping mold.   The apparatus includes a support frame with spaced plates and support bars interconnecting the plates, and a C-shaped opening formed in the plates.   An injector is included for injecting molding material into the self-clamping mold under pressure, and an extruder for providing molding material to the injector.  Temperature controllers are also provided for controlling the temperature of the molding material within the injector and extruder.  A lift mechanism supported on the frame provides clamped engagement between the self-clamping mold and the frame. During the injection operation wherein the injector is engaged with the mold, the lift mechanism clamps the mold to resist internal mold forces resulting from the injection of molding material.

Abstract: A microprocessor based overcurrent trip unit in-cludes an analog circuit for monitoring phase currents in the electrical interrupting device. The analog circuit is adapted to interface with the microprocessor over a range of selectable setpoints for instantaneous tripping and at the same time accurately monitor the phase currents even during a condition when the current sensing transformers are saturated. The overcurrent trip unit also allows the function of the long time delay characteristics of protec-tion curve to be varied in order to provide better coordi-nation with the characteristics of other overcurrent trip-ping devices in an electrical distribution system, such as a current limiting fuse, thereby enhancing the overall reliability of the system. For example, the function may be varied to provide either a fixed or FLAT, It, I2t and I4t function. The overcurrent tripping device also allows for relatively wide adjustment ranges for the long tine delay and short time delay protection portions of an overcurrent protection curve. In order to prevent any overlapping of the protection ranges, the long time delay portion is prevented from tripping the interrupting device prior to the short time delay portion.

Abstract: A gas chromatographic method utilizes columns having either ascending or descending temperature profiles to effect separation even under column overloading conditions. A fixed ascending temperature profile column allows for good separation of components of a mixture under conditions of column overloading. A mixture to be separated is chromatographed on at least one such column prior to chromatography on a column maintained with a descending temperature profile. This latter column has surprisingly been found to greatly reduce tailing of less volatile species. The invention also includes a variable temperature descending column chromatography to provide an initial ordering of a large quantity of components prior to chomatography on the fixed ascending temperature profile column, or on the serial fixed ascending and descending temperature profile pair of columns.

Abstract: ABSTRACT OF THE DISCLOSURE   A beverage cup lid is disclosed that comprises a circular closure panel, circumscribed by a side wall that terminates in a resilient, restricted diameteredge for capturing a brim of a beverage cup, and a frustro-conical skirt connected around the restricted diameter edge for increasing the hoop strength of the edge, and an extended diameter flange circumscribing the free edge of the skirt for further increasing the hoop strength of the restricted diameter edge such that the edge retains the brim with a force of at least 1 pound. The invention is particularly applicable to beverage cup lids formed by a plastic web machine that applies heat to only those areas that are deformed into structural components on the lid (such as the side wall, restricted diameter edge, and skirt), and which consequently results in some, amount of wall thinning in the skirt, and hence some reduction in the hoop strength that the skirt gives to the restricted diameter edge that retains the cup brim. The radial extent of the flange is large enough to increase the hoop strength, and hence retaining force of the restricted diameter edge by between .5 and 1.0 pounds.

Abstract: Disclosed is a method for the determination of urinary protein and creatinine in a single reaction vessel using a continuous process. The method involves adjusting the pH to a level suitable for carrying out an immuno assay for the protein and making such a determination by an immuno agglutination technique.      Raising the pH to a level suitable for determining the creatinine quickly dissipates the cloudiness caused by the agglutination reaction, so that the creatinine determination can be carried out without delay.

Abstract: The inventive methods employ symmetric encryption with first and second keys to provide secure access to information accessible to be shared among a dynamically changing set of authorized users on a network having a server.  A single copy of the information, encrypted with the first key of the server, is stored in a location accessible to all network users.  The second key is a private key of an authorized user and is used by the server to encrypt the first key.          The encrypted first key is then stored by the server at a storage location accessible by the authorized user.   The user accesses the storage location, obtains the encrypted first key, and uses his private second key to decrypt and thereby recover the first key.  The user then decrypts the stored information using the recovered first key.

Abstract: The present invention provides refrigeratable yeast-leavened dough compositions and methods of making such doughs. The dough's composition and the strain of yeast used therein are chosen to limit the total leavening action of the yeast by controlling the amount of substrate in the dough fermentable by the yeast or by inactivating the yeast at high temperatures. Dough compositions made in accordance with the invention are capable of being leavened at elevated temperatures, yet stored in a sealed container at refrigeration temperatures for extended periods of time. In a preferred embodiment the yeast used in the dough is substantially incapable of fermenting carbohydrates native to the dough and a predetermined quantity of a non-native carbohydrate fermentable by the yeast (e.g. galactose) is added to the dough to provide the desired amount of proofing. A diploid yeast is further provided with the further property of being inactive at low temperature.

Abstract: The present invention is a method of making discrete particles by subjecting an organic feedstock to liquiflash conditions whereby the feedstock is transformed instantaneously from solid to liquiform to solid. Liquiform is a transient condition wherein the feedstock has substantially unimpeded internal flow. Shear force is imparted to the liquiform feedstock in an amount sufficient to separate tiny masses of feedstock. The tiny masses solidify as discretized particles. The present invention also includes unique products resulting from the process, e.g., a monodispersed microsphere product and coated particles prepared therefrom.
