Title: Injection molding apparatus having mold cores with reverse taper
Inventor: MATYSEK PAUL RICHARD
IPC: B29C45/36
Filed: 1998-12-14
Abstract: Injection molding apparatus having an elongated cooled mold core (10) which forms an inner side (90) of the cavity (66). The elongated mold core (10) extends through an opening (92) through a core lock member (94). The outer surface (80) of the mold core (10) and the inner surface (120) of the opening (92) through the core lock member (94) have matching parts (118, 122) which taper inwardly towards the rear core (84) of the mold core (10). A nut (126) secures the mold core (10) to the core lock member (94) with the tapered parts (118, 122) abutting against each other. The reverse taper of these parts (118, 122) prevents injection pressure impact opening any space between them and thus prevents lateral core shift.

Title: Identification and comparison of protein-protein interactions and inhibitors thereof
Inventor: KNIGHT JAMES R
IPC: G16B30/10
Filed: 1997-06-13
Abstract: Disclosed are methods of detecting protein-protein interactions among two populations of proteins, wherein each protein population has a complexity of at least 1,000. Fusion proteins of each population are expressed in yeast cells of opposite mating types. The fusion protein populations are made by fusing to one population a DNA-binding domain of a transcriptional activator and fusing to the other population an activation domain of a transcriptional activator. When the yeast cells of opposite mating types are mated, productive interactions between members of each protein population functionally reconstitute the two domains of the transcriptional activator and result in reporter gene expression. The disclosed methods allow identification and characterization of new protein-protein interactions that may be relevant to a particular tissue or disease stage. Inhibitors of the identified protein-protein interactions can also be identified by screening for the ability to inhibit expression of the reporter gene. This inhibitor screening method can be performed in multiplex. Other aspects of the invention include information processing methods and systems. The methods and systems provide for assembling and processing of a unified database of sequences and identifying sequences that may be involved in protein-protein interactions.

Title: Method and apparatus for infusing fruit and for obtaining a substantial juice byproduct
Inventor: WETTLAUFER DALE E
IPC: A23L2/04
Filed: 1997-07-18
Abstract: Method and apparatus for infusing fruits (which may include vegetables) with sugar. The apparatus includes a series of interconnected tanks (t0, 12, 14 and 16). A stratified column of infusing liquor is caused to flow from a tank (50) via variable output pump (52) through fruit which is placed within the tanks to cause the fruit to become saturated with sugar. In addition, the fruit is placed in a plumping liquid in the tanks prior to infusing and the infusing liquor will drive the plumping liquid in front of it.     The fruit may be conditioned in various ways prior to placement in the tanks, which conditioning may remove fruit juice from the fruit, the fruit juice being collected in a tank (36) for subsequent use. Alternatively, if fruit juice is not removed from the fruit during a conditioning process, fruit juice is extracted from the downstream portion of the plumping liquid.

IPC: H04B7/185
Filed: 1999-04-06
Abstract: An extended band, multiple channel multiplexes 10 well-suited for use with satellite communications systems. The multiplexes utilizes a low attenuation, contiguous diplexer 18 containing contiguous diplexer filters 18a to combine two sections 11a, 11b of the multiplexes respectively containing contiguous channel filters 14a, 14b. The multiplexes comprises low attenuation, contiguous diplexer filters 18a tuned in tandem with channel filters 14a, 14b to provide contiguous multiplexing. This approach takes advantage of the constructive interaction between these filters to realize an equivalent contiguous multiplexes. This enables realization of a wide band contiguous multiplexes, which heretofore was impossible to tune. The contiguous diplexer eliminates spurious modes of the channel and diplexer filters, spurious waveguide modes, and out of band interaction between the two portions of the multiplexes. Therefore, tuning of the multiplexes is possible.

Title: Watermarking an information signal
Inventor: LINNARTZ JOHAN PAUL MARIE GERA
IPC: H04N7/26
Filed: 1998-08-17
Abstract: A method and arrangement for detecting a multi-bit watermark in a signal (e.g.  a video image) are disclosed. Each bit of the multi-bit value is represented by an embedded watermark subpattern in the signal. Instead of detecting in a conventional manner the presence of each individual subpattern (i.e. detecting each individual bit), the detection comprises the steps of: detecting (24, 23) the presence of the full watermark in the signal irrespective of its multi-bit value, and detecting (25) to which extent the presence of subpatterns corresponds with the multi-bit value to be checked. The reliability of watermark detection is hereby improved.

Inventor: HEAD PHILIP
IPC: E21B37/00
Filed: 1999-06-21
Abstract: An apparatus for removing debris from a bore hole, comprising a housing, and a cylindrical electric motor coupled coaxially to a direct drive pump.   The housing includes a debris entry port into which the debris is induced to flow into the housing, and the inside of the housing is maintained at a pressure which is lower than the outside pressure. The electric motor has a central bore through which material pumped by the pump can pass. The apparatus includes a head rotatable by the motor which engages the debris deposits in the bore hole. Where the pump is a direct drive worm pump, the head may be directly attached to the worm of the pump. In one embodiment, the housing extends along the whole length of the motor and pump, with the apparatus including a port settable to allow debris to be pumped into the housing from either end. Alternatively, a debris collection means may be included for effectively isolating any debris pumped by the pump from the bore hole. This debris collection means may be a pipe extending from the bore hole head to the motor and pump, or it may be a compartment attached to the motor and having a filter through which fluid may pass but which traps debris.

Title: Method and apparatus fro supporting multiple class of service connections in a communications network
Inventor: AISSAOUI MUSTAPHA
IPC: H04L47/80
Filed: 1999-07-21
Abstract: The method of the invention includes the step of transmitting a priority indicator containing information indicating the priority of network tragic over a connection to a downstream node in a communications network. The downstream node has a queue for queuing traffic received over the connection and the queue has an adjustable discard range. After transmitting the priority indicator, the network traffic is transmitted over the connection. When the priority indicator is received at the downstream node the discard range is adjusted to correspond to the priority indicated in the priority indicator. At the downstream node the network traffic is stored in the queue if a queue congestion measure is outside the discard range and discarded if the queue congestion measure is within the discard range. The priority indicator may be a Resource Management cell or may be provided in the header of a cell carrying the network traffic.
