Abstract: A series of images of a full motion video scene is divided into a number of sub-series which, when interleaved, represent the original series. A ranking order increasing magnitude is allocated to consecutive sub-series. Each image of a sub-series is converted into an image data block, while images from one or more sub-series having a lower order of precedence are considered for this conversion. A packet header indicating the ranking order of the sub-series with which the corresponding image is associated is added to each image data block.    The display apparatus is adapted to select those image data blocks which have predetermined packet headers and to subject the image data blocks thus selected to a decoding process. The number of different packet headers which is selected determines the temporal resolution of the scene to be displayed.

Title: Her3: a novel egf receptor homolog
Inventor: PLOWMAN GREGORY D
IPC: C12Q1/68
Filed: 1991-03-01
Abstract: ABSTRACT          The cloning, sequence and expression of a novel member of the EGFR/neu subfamily of receptor tyrosine kinases, termed HER3, is described.  The HER3 precursor comprises 1342 amino acid residues, 1323 residues of which comprise the mature HER3.  Recombinant HER3 does not interact with the homologous ligands EGF and TGF-.alpha..  A 160 kD phosphoprotein is present in cells expressing both HER3 and membrane-associated Amphiregulin, whereas the 170 kD EGF receptor is completely absent.  Immunoprecipitation experiments suggest this 160 kD phosphoprotein is HER3 and that it is present only when coexpressed with the integral membrane form of the AR precursor.

Title: Improvements in barrier seal systems
Inventor: VOLDEN DOUGLAS J
IPC: F16J15/40
Filed: 1991-03-11
Abstract: Case 067-1162-00 IMPROVEMENTS IN BARRIER SEAL SYSTEMS     Abstract of the Disclosure This invention relates to barrier seal systems for sealing the annular space between a housing and a rotating shaft which extends through a bore in the housing.  The seal system has inboard and outboard mechanical end face seals.  The inboard seal faces have spiral grooves for pumping a buffer fluid from a buffer chamber between the two seals toward the high pressure side of the inboard seal.  The primary ring of the inboard seal may be double balanced.  For high pressure applications, the buffer fluid may be pressurized and a pumping ring may be included in the outboard seal to circulate buffer fluid.  High pressure applications also require two hard seal rings and optimum dam and face widths.  Buffer fluid can be supplied to the seal system by a reservoir connected by a gravity feed line.  A buffer fluid containment device may be attached to the high pressure side of the seal to prevent process fluid from con-taminating the seal faces or secondary seals.

Abstract: A broaching insert, such as a slotter or semi-finisher, which cuts through a workpiece is configured such that side cutting edges of the broaching insert contact the workpiece simultaneously.  If the broaching insert is a slotter, a center portion of the cutting edge which interconnects the side cutting edges makes contact with the workpiece ahead of the side cutting edges.  If the insert is a semi-finisher, the side cutting edges are scalloped so as to reduce shock upon engagement with the workpiece.          The broaching insert is ideally suited to the cutting of workpieces oriented obliquely relative to the direction of cutting.  In order to minimize snap-back of the broaching insert as it exits the workpiece, the broaching insert is sequentially passed through back-up disks of gradually diminishing hardness, whereby the compressive loading on the insert is relieved gradually.
