Abstract: LATCH AND RETAINER MECHANISM   FOR ELECTRICAL CONNECTOR.          Abstract of the Disclosure An electrical connector has male and female housing halves each of which has front and rear housing portions.  The rear housing portion has an externally threaded front end, a stop shoulder at the rear extent of the threads and a hole to receive a latch pin.  The front housing portion has internal threads at the rear end to engage the threads on the rear housing portion and also has an end face with a recess.  The latch pin penetrates the rear housing near the stop shoulder and has a nonsymmetrical head.  The latch pin can be rotated between a position in which the head protrudes beyond the stop shoulder and a position in which it does not protrude beyond the stop shoulder.  When fully threaded together, the recess is aligned with the latch pin which can be rotated to its latching, protruding position to prevent unthreading of the housing portions.  The rear housing portion also contains a slidable cup which is elastomerically urged toward the front housing portion when the portions are assembled to maintain internal components in their proper position.

Title: Animal derived cell with antigenic protein introduced therein
Inventor: NICOLAU YVES C
IPC: A61K35/18
Filed: 1988-06-27
Granted: 1994-03-01
Abstract: ABSTRACT      This invention comprises animal derived cells, especially erythrocytes, which have been artificially modified (and referred to as enginerred erythrocytes or RBCs) so as to incorporate in their plasma membranes an antigen, CD4 protein derived from lymphocytes which will cause them to selectively seek out and fuse with other cells that are infected with a virus, especially the AIDS virus.  These modified cells can be further altered so as to contain in their cytoplasm a cytotoxic agent which, after the cell has fused with a target cell, will result in the pooling of their respective cytoplasms and the death of both cells, with subsequent removal by the reticuloendothelial system.  The invention also includes the production and use of similarly modified liposomes. The present invention can be used a treatment of Acquired Immune Deficiency Syndrome (AIDS), e.g. where the antigen on the modified cell is advantageously the CD4 antigen of animal lymphocytes and the target cell is an animal cell infected with the AIDS virus.  This invention also relates to treatment of disease conditions, especially viral diseases and most notably AIDS, by injecting into a patient so afflicted a therapeutically effective amount of antigenically modified cells containing a cytotoxic substance.  Such modified cells and liposomes can also be used as a basis for an in vitro diagnostic assay involving cells derived from the blood of patients suspected of having AIDS.

The refrigeration system has a local control apparatus for operating the system in response to local status signals and has remote control input ports for remote control of the system.  A remote electronic controller adapted to receive the local status signals and to override at least part of said local control means operates the refrigeration system by generating an electrical control signal and a switchback signal indicating that the electrical control signal should be recognized.  The interface adapter electronically isolates and interfaces the refrigeration system and the remote controller.          The interface adapter includes a circuit responsive to the switchback signal for providing the electrical control signal of the remote controller with the remote input ports of the refrigeration system.  The interface adapter may also include a circuit for providing at least one of the local status signals to the remote controller.  As a result, the interface adapter permits a corresponding control signal to be provided to the remote control input port of the system even though the electrical characteristics of the remote control input port may be incompatible with one of the corresponding electrical characteristics of the control signal.

Title: Protamine-reactive igm antibodies
Inventor: RODMAN TOBY C
IPC: C07K16/00
Filed: 1989-03-21
Granted: 2000-05-02
Abstract: The present invention is directed to protamine-reactive, IgM antibodies, and their uses in prognosis, diagnosis, and therapy. In a specific embodiment, the invention relates to low affinity binding, protamine-reactive serum IgM antibodies.      In particular, such antibodies can recognize a sequence comprising four arginyl residues, including a triplet, within a six amino acid residue sequence. Such antibodies may be natural antibodies (i.e., not induced). A low affinity subset of serum protamine-reactive IgM antibodies may be assayed for prognosis or diagnosis of AIDS. Such antibodies are detectable in sera of normal subjects and HIV-infected individuals who subsequently exhibit a significant period of latency, but are absent or deficient in sera of individuals diagnosed with AIDS and sera of HIV infected individuals, who though asymptomatic at the time of the sampling, proceed to AIDS within a relatively short time.   The invention provides methods and diagnostic kits for the detection and/or measurement of the low affinity subset of protamine-reactive serum IgM antibodies, for the prognosis and diagnosis of AIDS and other immune system abnormalities.
