Title: Human tumor necrosis factor
Inventor: WALLACE ROBERT BRUCE
IPC: C12P21/02
Filed: 1985-04-03
Granted: 2002-03-19
Abstract: A human physiologically active polypeptide, human Tumor Necrosis Factor (human TNF), comprising a specific amino acid sequence of 155 amino acid residues. The base sequence of the DNA coding for the human TNF has been determined using rabbit TNF cDNA. The human TNF can be advantageously produced on a large scale by recombinant DNA technique. The human TNF of the present invention has been found to be excellent in inducing necrosis of tumours with no toxic effect upon the a normal tissues of the living body.

Abstract: SPECIFICATION     1.   TITLE OF THE INVENTION:    ROTARY TYPE FLUID MACHINE   2.  ABSTRACT OF THE DISCLOSURE:      A rotary fluid machine of the type including two spiral elements, or a stationary spiral element and a revolving spiral element having substantically an identical configura-tion and disposed therein 180 degrees apart from each other in mutually nested relationship, the revolving spiral ele-ment being adapted to revolve in solar motion relationship with respect to the stationary spiral element with a radius of revolutionary motion ?, in which the both spiral elements are respectively defined in profile with a radially outer curve segment consisting of an involute curve, a radially inner curve segment consisting of another involute curve in an arc having a radius R, and an arc of a radius r connecting smoothly the radially outer curve segment and the arc having the radius R, whereby the radially inner leading end of the spiral elements incorporated may well be protected from possible damages as encountered during the operation of the machine, and the height of spiral elements may readily be increased substantially without making greater the overall outer diameter of the spiral elements, to make larger capacity of the machine.

Granted: 1992-09-08
Abstract: A method of building a structure formed of a masonry wall having an outer face carrying frame members and insulation and provided with sheathing overlying the frame members and insulation entails generally simultaneously erecting the masonry wall, frame members, and insulation and thereafter applying the sheathing. More particularly first a framework of frame members is erected against an outer brace panel, insulation is fitted between the frame members and against the brace panel, and anchors are fixed to the insulation and framework with stems of the anchors projecting inward away from the panel past the insulation. Then a masonry interior wall either of cast reinforced concrete or block is built against the insulation with the anchors imbedded in the masonry wall. The outer brace panel is then removed and sheathing is secured to the frame members. Thus the exterior walls of the building can be virtually completed, all but the sheathing, one floor at a time. The masonry wall is built after the framework and insulation are set up, working from inside, so that the use of heavy-duty scaffolding and the like is unnecessary.

Title: Method for the decaffeination of roasted coffee extracts and the products thereof
Inventor: MEINHOLD JAMES F
IPC: A23F5/22
Filed: 1986-10-10
Granted: 1991-12-17
Abstract: METHOD FOR THE DECAFFEINATION OF ROASTED COFFEE EXTRACTS AND THE PRODUCTS THEREOF            ABSTRACT OF THE DISCLOSURE A method of decaffeinating aqueous roasted coffee extracts is disclosed.  An organic caffeine solvent is first loaded with essentially hydrolyzed coffee solids.  The aqueous roasted coffee extract is contacted with the loaded organic caffeine solvent for a sufficient period of time to transfer at least some of the caffeine from the coffee extract to the caffeine solvent, whereupon the extract is separated from the caffeine-containing solvent.  The resultant coffee extract has been found to have noticably more body notes than a coffee extract which is decaffein-ated with a solvent that has not been loaded with hydrolyzed coffee solids.

Title: Electrical receptacle terminal
Inventor: RAHRIG THOMAS F
IPC: H01R13/115
Filed: 1987-03-24
Granted: 1992-05-12
Abstract: Abstract Electrical Receptacle Terminal An electrical receptacle terminal having a longitudinal body for receiving a pin terminal includes a bifurcated beam spring forming two spring arms.  The two spring arms act independently to urge an inserted pin terminal into good electrical contact with an opposing rib formed in an opposing wall. Each spring arm also includes a respective side flange which is contoured to engage the pin terminal in quadrature with the spring arms and rib.  The pair of flanges have opposed faces for engaging opposite sides of the pin terminal.  The spacing of the opposed faces of the flanges is normally less than the dimension of the pin terminal they engage such that they and the spring arms are resiliently spread by the pin terminal to thereby provide secure engagement.  The four walls of the receptacle terminal are folded inward and rearward to form a continuous entry aperture and also to provide the spring arms.

Title: Apparatus and methods for making differentially-conditioned package pairs
Inventor: NIXON HENRY M JR
IPC: B65B7/28
Filed: 1988-06-03
Granted: 1992-05-05
Abstract: ABSTRACT OF THE DISCLOSURE         Different products are hermetically sealed in separate but integrally adjoining packages to form pack-age pairs or what might be called "dual" packages.  All of the packages are made from two continuous sheets of plastic packaging material, and the separate packages of each pair are differentially-conditioned by differential evacuation and/or gassing to different pressure levels. A continuous series of filled side-by-side containers formed from one sheet of packaging material is conveyed in two parallel rows into a sealing region where a cover sheet is laid over the containers to form packages.  A group of the packages is stopped in the sealing region, and are clamped and partially sealed around the periph-eries of the individual packages.  The individual side-by-side units of the package pairs are differentially conditioned as to vacuum pressure or gas pressure or composition through aligned openings between adjacent containers in each of the parallel rows. The aligned openings and the remainder of the peripheries around the package then are sealed, and the completed package pairs are removed from the sealing region. The differential conditioning of the package pairs may be by way of dif-ferential evacuation, or evacuation followed by back-filling the packages with different pressures of gas, or other combinations.
