Title: Injector with retractable shroud
Inventor: PHILLIPS IAN ROSS
IPC: A61M5/20
Filed: 1994-11-14
Granted: 1999-07-13
Abstract: An injector (10) having a needle (14) which is exposed by a retractable shroud (13). Mounted within the body (11) of the injector (10), is a first interacting piston (30) and cylinder (31) which cooperate to enclose a first space (33) which receives the liquid to be injected. A second interacting piston (26) and cylinder (27) cooperate to enclose a second space (28). A gas under pressure is delivered to the second space (28) to cause movement of the second piston (26). The second piston (26) is attached to the first piston (30) and therefore moves with it. The shroud (13) is operatively associated with a valve (35) to regulate the delivery of the gas under pressure to the space (28) to cause operation of the injector (10). A user of the injector (10) grips the body (11) by means of a handle portion (12) and presses the injector (10) against the skin of the animal. This causes retraction of the shroud (13) as the needle (14) penetrates. That retraction of the shroud (13) then causes actuation of the valve (35) to cause operation of the injector (10).

Abstract: A self righting walking cane device which comprises a lightweight hand grip handle, a lightweight shaft device and a bottom weighted base device to facilitate the righting action of the cane device.   The base device  includes a plurality of frame devices and faceted shell sections which are attached about the bottom portion of the shaft device.          The frame devices or shell have a unique configuration which together with the weight device positioned about the bottom portion of shaft device which together with unique shaft configuration provide a unique self righting walking cane.          This combination of elements produces a cane whose center of gravity is below the center of rotation of the righting surface causing the cane to remain vertically stable and if disturbed from its vertical position to return to it.  The construction of the cane device also allows it to stand by itself without the need of support.

Title: Deoxygenation of cis vicinal diols
Inventor: CLIVE DERRICK LAWRENCE JOEL
IPC: C07H19/06
Filed: 1994-02-01
Granted: 2003-10-21
Abstract: Cis vicinal diols are converted to olefins using tellurides or selenide reagents. The diol is reacted to convert the hydroxyl groups into good leaving groups for nucleophilic substitution. Alkyl and aryl sulfonate groups such as mesylate or tosylate are preferred. The product is then reacted with a source of Tc2- or Se2- ions, preferably an alkali metal telluride or selenide, to form the desired olefin. The process is particularly useful for generating 2',3'- unsaturation in the sugar moiety of nucleosides. Novel intermediate mesylate, tosylate and olefin derivatives of nucleosides are also provided.

Title: Diagnosis and treatment of supravalvular aortic stenosis and williams syndrome
Inventor: KEATING MARK T
IPC: C12Q1/6883
Filed: 1994-04-04
Granted: 2009-07-07
Abstract: The invention relates to the identification of the molecular basis of supravalvular aortic stenosis (SVAS) and Williams syndrome. More specifically, the invention has identified that elastin causes or is involved in the pathogenesis of SVAS and Williams syndrome. Molecular variants of the elastin gene contribute to SVAS and Williams syndrome. The analysis of the elastin gene will provide an early diagnosis of subjects with SVAS and Williams syndrome. The diagnostic method comprises analyzing the DNA sequence of the elastin gene of an individual to be tested and comparing it with the DNA  sequence of the native, non-variant elastin gene. In a second embodiment, the elastin gene or an individual to be tested is screened for mutations associated with SVAS or Williams syndrome. Presymptomatic diagnosis of SVAS and Williams syndrome will enable practitioners to prevent vascular obstruction using existing medical therapies like beta adrenergic blocking agents.

Title: Refrigerated cargo container
Inventor: CLATERBOS JOHN K
IPC: F25D3/12
Filed: 1995-03-21
Granted: 2005-08-30
Abstract: A system for maintaining a cargo in a refriger- ated condition over an extended duration employs an insulated enclosure having both a cargo-enclosing por- tion (25) and a carbon dioxide-enclosing portion (28) separated by an insulated barrier (32). A finite amount of solid carbon dioxide is placed in the carbon dioxide- enclosing portion (28) at the beginning of the dura- tion. By properly insulating the barrier to provide a rate of heat transfer within a predetermined range the cargo is maintained in a refrigerated condition with- out replenishing the solid carbon dioxide for uniquely lengthy durations. Such durations are especially max- imized by employing such enclosures in the form of cargo-carrying containers of generally rectangular shape stackable vertically atop one another and or in close side-by-side relation to one another.

IPC: H03H17/00

Granted: 1999-07-27
Abstract: A center-line filter for a radar receiver (50) is a cascade of an analog filter  (54A)  and a digital filter (58A).  The purpose of the filter cascade is to filter out all but a single line of a pulsed spectrum.  The signal is passed through the analog filter, and then over-sampled by an analog-to-digital convertor (56A).  A sharp cutoff FIR filter is used as the digital filter (58A) to eliminate the remaining undesired lines.  Since the analog filter already has  the  correct  matched  filter  characteristic  in  the passband, the digital filter passband is deliberately wider and unsymmetrical.   After digital filtering, the filter output is decimated by a decimation processor  (60A)  to provide a desired output data rate.

Granted: 1999-11-23
Abstract: A method and apparatus are provided for stabilizing at least one element of a mechanical system against echo-like responses to mechanical disturbances.  One or more error signals are provided by sensing the motion of the system at one or more points. At least one adaptive filter is operated in response to the error signal or signals, and in response to at least one non-advanced reference signal that is directly related to some motion of the system. The adaptive filter produces a corrective signal for driving a mechanical actuator, thereby to apply to the element a stabilizing generalized force. By non-advanced is meant that there is a zero or negative time-delay between the presence of a given signal at the reference-sensing location and the arrival of the same, or a similar, signal at the error-sensing location.  In particular embodiments of the invention, the reference-sensing location is the same as the error-sensing location.

Title: Rapid expansion method ("rem") for in vitro propagation of t lymphocytes
Inventor: RIDDELL STANLEY R
IPC: A61K39/00
Filed: 1995-08-31
Granted: 2010-03-30
Abstract: The present invention provides a rapid expansion method (termed 'REM"), for quickly generating large numbers of T lymphocytes, including cytolytic and helper T lymphocytes. REM involves culturing the T cells in association with a disproportionately large concentration of nondividing feeder cells, preferably .gamma.-irradiated peripheral blood mononuclear cells ('PBMC") present at an excess of at least 40-fold (relative to the number of target T cells), more preferably at an excess of at least about 200-fold. Cultures grown under REM exhibit dramatically enhanced expansion rates that can be even further elevated by the use of appropriate concentrations of an additional feeder cell, an anti-CD3 monoclonal antibody and IL-2, as described herein. Clonal expansions in the range of 500-fold to 3000-fold can be achieved within a single stimulation cycle of about 10 -13 days, which is more than 100-fold more efficient than currently employed methods of culturing human T cell clones. Genetic transduction efficiencies were also enhanced using REM-expanded T lymphocytes. Several examples involving human bone narrow transplant recipients illustrate the effective use of REM-expanded antigen-specific cytotoxic T lymphocytes for adoptive immunotherapy in humans.
