Title: Ground coil for magnetically levitated railway sealed by synthetic resinforming reactive liquid
Inventor: SUZUKI MASAO
IPC: H01F5/06
Filed: 1991-10-29
Abstract: In order to produce a ground coil for a magnetically levitated railway, coils each composed of a conductor coiled in a plurality of turns are arranged in a metal mold, and a synthetic resin forming reactive liquid is injected and cured in the metal mold by reaction injection molding.    Furthermore, a plurality of base coils are produced each composed of a coil conductor coiled in a plurality of turns in a desired shape, laid in two tiers and connected in series so as to form unit coils.  Two unit coils are connected so that the winding directions of them are opposite to each other and guidance terminals are formed, thereby forming a pair of levitation and guidance coils.  Two pairs of levitation and guidance coils are arranged on a single plane in a metal mold so that the positional relationship among the coils is constant, and a synthetic resin forming reactive liquid is injected and integrally cured by reaction injection molding.

Title: Chemically modified hemoglobin as an effective, stable, non-immunogenic red blood cell substitute
Inventor: DAVIS FRANK
IPC: A61K38/16
Filed: 1990-11-21
Abstract: ABSTRACT OF THE DISCLOSURE             The present invention relates to chemically modified hemoglobin produced by a novel and efficient method in which stroma-free hemoglobin is first effectively deoxygenated and reduced and then conjugated with a polyalkylene oxide such as polyethylene glycol (PEG) under conditions which maintain the structural integrity of the heme oxygen binding site.   In specific,  preferred embodiments of the invention,  the deoxygenation and reduction is performed under an inert atmosphere by the amino acid cysteine.   In additional specific, preferred embodiments, the structural integrity of the heme oxygen binding site is maintained by a high anionic concentration in the reaction mixture.   In further preferred specific embodiments of the invention, the polyalkylene oxide is polyethylene glycol; in still further preferred specific embodiments of the invention, the polyalkylene oxide is linked to hemoglobin via a urethane (carbamate) linkage. The novel PEG-modified hemoglobin compounds of the invention exhibit superior oxygen transport capabilities, extended half-life, and importantly, low immunogenicity.

Title: Multi-media serial line switching adapter for parallel networks and heterogenous and homologous computer systems
Inventor: OLNOWICH HOWARD T
IPC: H04L69/14
Filed: 1992-07-09
Abstract: ABSTRACT OF THE DISCLOSURE            A generic network device includes a serial line switching apparatus   for  performing  either  parallel   or   serial communications  amongst  multiple  nodes  over  switching networks.   One  aspect  shows  adaptation  of  standard  and proprietary  serial  interfaces  using  either  optical  or electrical transmission media to interface to the parallel switch.   Converted serial data is routed to the selected destination through the parallel switch network, where it is received  and  converted  back  into  a  serial  optical  or electrical interface/protocol.  A parallel electrical switch can efficiently handle optical or electrical serial data and utilize information via wireless gateways to provide the features  required for  parallel  processing  and  "farm" approaches,   such   as   low   latency,   high   bandwidth, scalability,  fault  tolerance,  and  high  reliability.   In addition,  flexibility  is  provided  which  permitting  the switching adapter to be personalized to support any one of a number  of  standard  and proprietary  serial  protocols.   A personalization  PROM  specifies  the  particular   serial protocol that each individual adapter is to support.  The parallel  switching network becomes a flexible media that interconnects  and  allows  different serial  protocols  to communicate with each other; i.e., any number of different serial protocols can interface with the same parallel switch network.  However, a node is not restricted to communicating only with  other  nodes  using  the same  protocol;  it  can communicate with any of the other nodes regardless of the serial  protocol  they  use.  The  switch  enables  generic networks with heterogeneous and/or homologous nodes  as a computer system.

Patent CA-2075462-A1 (CA)
Title: Bump structure and method for bonding to a semi-conductor device
Inventor: ERDOS GEORGE
IPC: H01L21/60
Filed: 1992-01-27
Abstract: A bump structure for bonding leads to a semi-conductor, in which the bump has a thin lower portion which overlaps and seals the edges of the passivation layer, and a thicker upper or stem portion of smaller lateral  dimensions  to  fit within the margins  of  the opening in the passivation layer.  Thus, during bonding, downward compressive forces are applied primarily through the bump stem directly to the metal  termination pad beneath the bump, and very little force is applied to the edges  of  the  passivation  layer.    This  reduces  the likelihood  of  passivation  layer  cracking,  increasing device reliability.   Because the bump stem is  formed within the margins of the passivation layer opening, it has a flat top, resulting in better lead bonding.

IPC: B65H33/14
Filed: 1991-08-30
Abstract: A stacking device for forming stacks of articles of predetermined count, using a stacking wheel (12) having a multiplicity of uniformly spaced peripheral slots (24).  The slots are adapted to receive articles (16) sequentially at a loading station (10) and carry them to an unloading station (14) having a plurality of stacking sites.  The slots are divided into two or more sets (S, L) the slots in each set being equal in number to the predetermined count and adapted to deliver the articles therein to the unloading station with the leading edges of the articles at a predetermined radial offset from the axis (28) of the stacking wheel.  Each set of slots is associated with the stacking of articles at a specific stacking site (64) and the slots of a set associated with one stacking site provide a different radial offset than those of a set associated with another stacking site.  The stacking sites are arranged, in the downstream direction, in order of diminishing radial offset of their associated sets of slots.  Separation of the stacks is effected by having stripping fingers (58, 60) for each stacking site act at the appropriate radial offset.

Abstract: RECLOSABLE LABEL PACKAGE                         Abstract A reclosable and resealable label package is provided which minimizes the amount of packaging necessary for retail display and marketing of labels.  The package includes a set of labels formed within a label layer which has a lateral portion surrounding the layers.  A top cover sheet is releasably adhered to the label layer only in the lateral portions thereof so that it can be peeled back to allow access to the labels and resealed to reclose the package.  The provision for the transparent top cover sheets both obviates the need for any ancillary packaging and provides clear access through the cover sheet so that marketing indicia can be printed directly on the label layer and still be available for viewing by the consumers who may wish to examine the attributes of the product.

Title: Trailer anti-theft device
Inventor: MOR YITZCHAK
IPC: B60T17/16
Filed: 1993-07-02
Abstract: ABSTRACT An anti-theft device is coupled in series with a supply line and a service line of a trailer.  When activated, the anti-theft device prevents theft of the trailer by decoupling the supply and service lines of the trailer from the reservoir and brake cylinders of the trailer, and by coupling the supply and service lines to the atmosphere, thereby preventing a prospective thief from releasing the trailer's brakes by restoring air to the supply and service lines.  When the anti-theft device is deactivated, the supply and service lines are re-coupled to the reservoir and brake cylinders to allow the driver to release the trailer brakes.
