Title: Syringe assembly
Inventor: SZWARC JOSEPH M
IPC: A61M5/178
Filed: 1990-11-19
Granted: 1994-03-29
Abstract: SYRINGE ASSEMBLY                      ABSTRACT       A  hypodermic  syringe  assembly  includes  a barrel having an open proximal end, a chamber for retaining fluid and a tip portion extending from a distal  end  of  the  barrel  having  a  passageway therethrough  communicating  with  the  chamber.   A needle cannula having a distal end extends outward-ly from the tip portion and includes a lumen in fluid communication with the passageway.  A needle shield assembly includes a resilient needle sheath having an open proximal end, a closed distal end, a sidewall  defining  a  receptacle  therein  and  is positioned within an elongate rigid shield having an open proximal end, a distal end and a sidewall therebetween.   Structure  for  holding  the  sheath within the shield is provided so that the sheath cannot be removed from the shield during normal use of  the  syringe  assembly.   The  sheath  includes cannula sealing means at  the  distal  end  of  the receptacle.    The   needle   shield   assembly is positioned  with  the  distal  end  of  the  cannula engaging the cannula sealing means and the proximal end  of  the  sheath  removably  engaging  the  tip portion to hold the needle shield assembly on the barrel while simultaneously sealing the lumen of the cannula so that the sheath surrounds the entire portion of the cannula which extends outwardly from the tip portion of the barrel.

IPC: F16L33/04
Filed: 1990-12-05
Granted: 1997-11-18
Abstract: A band made from a material normally elastically non-stretchable in its longitudinal direction to which elastic stretchability is imparted by one or more sections which include lateral non-rectilinear band portions on both sides of the central longitudinal band plane.  The lateral non-rectilinear band portions are thereby made by cut-outs in the band along its longitudinal sides and in the center area.  In one embodiment, the cut-outs along the sides are segmentally shaped while a window in the central area is made of a shape resembling an hourglass.  Adjacent sections are connected with each other by transversely extending web portions delimited in the longitudinal direction by end surfaces of the central cut-outs.  A clamp structure utilizing a band of the aforementioned type, especially a clamping band made from galvanized or stainless steel, offers numerous advantages, especially if a so-called "Oetiker" ear is used to tighten the clamp structure about the object to be fastened thereby.  This is so because changes in the circumferential length of the clamp structure will be compensated thereby in the first instance by the elastically stretchable clamping band so that greater latitude exists in the design and installation of such a plastically deformable ear which can now be designed and closed to maximize its holding ability.

Title: Faraday effect current sensor
Inventor: LUTZ DALE R
IPC: G01R15/24
Filed: 1991-03-18
Granted: 2000-05-16
Abstract: In known Faraday effect current sensors, light is fed into a polarizer, through a coil of field-sensitive optical fiber, and into a polarization measuring device.      Such a current sensor can provide greater accuracy of current measurement by using a polarizing optical fiber as its polarizer and splicing the polarizing fiber to the input end of the optical fiber coil. The exit end of the optical fiber coil can be spliced to a second polarizing optical fiber, the other end of which is optically connected to a photodetector. In another embodiment, a mirror at the exit end of the optical fiber coil reflects light back through the coil to second and third polarizing fibers which in turn are optically connected to a pair of photodetectors, thus doubling the Faraday rotation while canceling out reciprocal optical effects.

Title: Apparatus and method for detecting contraband using fast neutron activation
Inventor: GOZANI TSAHI
IPC: G01V5/00
Filed: 1991-01-09
Granted: 2001-10-30
Abstract: An apparatus and method non-invasively interrogates an object (134) to detect contraband. The ap-paratus irradiates the object (134) with fast neutrons of energy greater than 6.7 MeV, and measures the ensu-ing gamma-ray spectra. Irradiation of the object is accomplished by produ-cing a neutron beam (132) and mov-ing the interrogated object stepwise or continuously relative to the beam.      The nuclear interactions of highly penetrating neutrons within the irra-diated volume of the object give rise to energetic nuclear-species character-istic gamma-rays. The energy and intensity of the emitted gamma-rays provide information relative to the spatial arid density dis-tributions of the gamma-ray sources, i.e., the specific atomic nuclei within the object. From this information, three-dimensional images of the atomic nuclei spatial and density distributions are inferred.  Such three-dimensional images allow a decision to be made as to the presence of contraband. Measurements are made using arrays (144) of gamma-ray scintillator detectors. A deci-sion analysis based on statistical methods (e.g., discriminant analysis) or an artificial neural system, or other expert system, facili-tates a low false alarm rate. One embodiment of the apparatus includes neutron beam collimator means (136) to define and limit the irradiation volume of the objet, and auxiliary neutron shielding means (135) to attenuate the neutrons in other than desired neutron beam direction(s). Another embodiment includes an X-ray system (150) and combines electron density information ob-tained from an X-ray image of the object with the spatial and density distribution information of the gamma-ray sources in order to further enhance the decision analysis.

Title: Extruded foods containing high amylose starch
Inventor: LACOURSE NORMAN
IPC: A23L7/10
Filed: 1992-03-30
Granted: 1996-10-22
Abstract: The present invention provides a method for preparing semi-moist or dry, low water activity, extruded foods, comprising the steps: (a) formulating a food for extrusion, comprising 1-15% water and an effective amount of a soluble high amylose starch, up to 75% by weight, selected from: (1) spray-dried, non-granular starch, characterized in that the starch is substantially non-crystalline, substantially non-retrograded, and fully pre-dispersed; (2) spray-dried, uniformly gelatinized starch in the form of granular indented spheres, with at least a majority of the granules being whole and unbroken, the starch granules being in the form of loosely-bound agglomerates or individual granules; (3) enzymatically debranched soluble starch, comprising at least 65% amylose; (4) an enzymatically debranched, gelatinized starch, containing crystalline short chain amylose and comprising at least 65% amylose; (5) a pre-extruded, fully predispersed high amylose starch; and (6) a combination thereof; and .(b) extruding the foods at a temperature of up to 160°C and a pressure of up to 35.2 kg/cm2 (500 psi). The low water activity extruded foods prepared with soluble high amylose starch are characterized by one or more of the following beneficial properties: improved expansion during extrusion, improved appearance, improved air-, oil-and/or water-impermeable surfaces; and improved textures. These foods are easier to prepare when they contain the soluble high amylose starches herein, since these starches, in contrast to granular high amylose starches used in the same foods under normal extrusion condition, can be completely and thoroughly dispersed in the extruded foods without chemical modification of the starch, or significant alteration of typical food extrusion processes.

Title: Inhibition of lymphocyte adherence to vascular endothelium utilizing a novel extracellular matrix receptor-ligand interaction
Inventor: WAYNER ELIZABETH
IPC: A61K39/395
Filed: 1990-08-31
Granted: 2001-05-29
Abstract: The present invention relates to a method for inhibiting the adhesion of one cell to another comprising interfering with the interaction between the extracellular matrix receptor and its ligand. The invention is based upon the discovery that the .alpha.4.beta.1 extracellular matrix receptor promotes adhesion of lymphocytes to endothelial cells via attachment to a defined peptide sequence. Prior to the present invention, the ligand of the .alpha.4.beta.1 receptor had not been identified, nor had the function of the .alpha.4.beta.1 receptor in lymphocyte attachment been known. By preventing the interaction between the .alpha.4.beta.1 receptor and its ligands using antibodies or defined peptide sequences, the present invention enables, for the first time, specific intervention in the migration of lymphocytes through the vascular endothelium and into tissues. The present invention, therefore, has particular clinical utility in suppression of the immune response; in various specific embodiments of the invention, the adherence of lymphocytes to endothelium may be inhibited systemically, or may, alternatively, be localized to particular tissues or circumscribed areas. Accordingly, the present invention provides for treatment of diseases involving autoimmune responses as well as other chronic or relapsing activations of the immune system, including allergy, asthma, and chronic inflammatory skin conditions.

Title: Helical conveyor food freezer
Inventor: LANG GARY DEE
IPC: B65G17/06
Filed: 1990-11-06
Granted: 1997-03-11
Abstract: A freezer (10) includes an insulat-ed enclosure (12) for maintaining low temperatures therewith and a conveyor belt (20) that carries food products throughout the enclosure (12). The con-veyor belt (20) includes a straight-line path section (40) and at least one helical path section (22a) and is driven by verti-cal drive elements (32) carried by a rotat-ing drum (28) about which the conveyor helical path section (22a) is located. Up-on entering a helical path section (22a) from a straight-line path section (40), the conveyor belt (20) undergoes expansion only, with the inner ends of its transverse rods (52) maintaining a precise spacing which allows smooth    interengagement between heads at the inboard ends of the rods (52) and the leading surfaces of the vertical drive elements (32) that are locat-ed along the circumference of the rotat-ing drum (28) which defines the curved helical path (22a). Because of the im-proved arrangement, both an ascending helical path and a descending helical path can be established within a single freezer with both rotating drums (28) simply driven by a single motor (30).

Title: Dispensing apparatus
Inventor: CRUYSBERGHS RUDIGER JOSEF CHAR
IPC: B65D83/66
Filed: 1991-09-05
Granted: 1995-08-29
Abstract: An apparatus for dispensing product from a container in which first and second members are provided in a vessel which is disposed in the container.  The first member defines with the vessel a first chamber, and the second member defines with the first member a second chamber.  One of the members moves in response to the pressure in the container to a first position relative to the other member and pressure is exerted in the second chamber on said first member to move it to a second position in response to the pressure in the container decreasing below the predetermined pressure.  When the first member moves to the second position the first chamber is connected with the container to permit the pressurized gas in the first chamber to pass to the container and when the first member moves to the first position this connection is disconnected to prevent the passage of the gas.

Title: Optical device
Inventor: JENKINS RICHARD MICHAEL
IPC: G02F2/00
Filed: 1991-12-02
Granted: 2003-04-22
Abstract: An optical device (10) incorporates a rectangular multimode waveguide (14) with an input aperture (22), and two output optical fibres (26 and 28) with respective input apertures (30 and 32). An input light beam (34) of Gaussian transverse intensity profile is focussed to a beam waist (36) at the centre of the aperture (22).  The beam phase and waist radius w are arranged such that the light beam (34) excites symmetric modes in the waveguide (14). Modal dispersion along the waveguide (14) produces two electric field intensity maxima of similar magnitude centred on the fibre input apertures (30 and 32). This provides the beamsplit-ter function of division of input radiation into two similar intensity outputs. Devices of the invention may be arranged to divide input beams into more than two output beams. The invention may also provide a light beam combiner.
