Inventor: HAEGERT FRITZ W
IPC: B62D35/00
Filed: 1986-06-10
Granted: 1991-06-11
Abstract: AERODYNAMIC STRUCTURE FOR SEMI-TRAILER TRUCKS    ABSTRACT OF THE DISCLOSURE        A highway tractor cab is provided with a rigid aerodynamic structure, which may also be on the cab roof, which extends the sides of the cab and/or roof deflector beyond the rear wall of the cab toward a semi-trailer articulatedly connected to the tractor.  A flexible side extension member, which is deformable on contact with the trailer but has a high degree of shape retention in the absence of such contact, is attached to the rear edge of the rigid structure and has an outer surface disposed to form an aerodynamically efficient continuation of the outer surface of the rigid structure.  Preferably, the flexible side extension is wedge-shaped and is attached by a T-in-slot connection to a slotted tube mounted to the rigid structure completely inwardly of the outer surface thereof to avoid disturbing the air stream passing therealong.

Granted: 1992-02-18
Abstract: ABSTRACT OF THE DISCLOSURE       A method is taught for increasing the yield of anhydrous sodium dithionite by adding an organic compound that is thiosulfate reactive to a batch reactor containing a puddle solution of methanol and fed with formic acid or an alkali formate as a first feed, an aqueous alkali compound as a second feed, an aqueous alkali formate solution as a third feed, and a methanolic SO2 solution as a fourth feed.  This organic compound may be added prior to, combined with, or concurrently with one of the four feeds to the reactor.  Preferably, it is added concurrently with the third feed and throughout the entire course of the reaction, ending with the beginning of the cooling period.  A suitable addition rate is 0.4-0.6 wt.%/minute, preferably 0.5 wt.%/minute.  All of the organic compound is consumed, and at least a portion of the thiosulfate ion is destroyed.  The organic compound is selected from the group consisting of epoxy compounds having the formula   or  halogenated hydrocarbons having the  general formula R2X or XR2X, R1 being hydrogen, an alkyl group containing from 1 to 8 carbon atoms, a halogenated alkyl group containing from 1 to 2. carbon atoms, a phenyl group, or a substituted phenyl group.

Title: Activation of macrophage tumoricidal activity by granulocyte-macrophage colony stimulating factor
Inventor: COSMAN DAVID J
IPC: C07K14/535
Filed: 1986-08-15
Granted: 2000-11-21
Abstract: Macrophages and precursor monocytes are activated to exhibit tumoricidal activity by stimulation solely with granulocyte-macrophage colony stimulating factor. A patient suffering from tumors can be treated by direct administration of therapeutically effective quantities of activated granulocyte-macrophage colony stimulating factor. Homogeneous granulocyte-macrophage colony stimulating factor for use in activating macrophages and monocyte precursors is prepared by recombinant DNA techniques. The gene coding for granulocyte-macrophage colony stimulating factor is isolated and then recombinant protein product expressed in an appropriate expression system. The granulocyte-macrophage colony stimulating factor recovered from the expression system is purified to homogeneity by reverse phase high-performance liquid chromatography.

Granted: 1991-04-02
Abstract: COLORIMETRIC GAS DOSIMETER               ABSTRACT OF THE DISCLOSURE          A colorimetric gas dosimeter, which contains a granular indicator substance in a closed, transparent, hollow unit that can be opened on one side, is proved in such a way that the diffusion cross section for the hazardous substance molecules is independent of the degree of discoloration of the indicator substance and the detection sensitivity  is thereby increased. This is achieved by sub-dividing the hollow unit into several chambers extending along its longitudinal axis, at least one of which is filled with the granular indicator, and is located adjacent to an indicator free chamber and is separated from this by a separating wall permeable to gas.

Title: Sprayer having induced air assist
Inventor: CORSETTE DOUGLAS F
IPC: B05B11/00
Filed: 1987-05-29
Granted: 1991-07-02
Abstract: ABSTRACT OF THE DISCLOSURE          Spray discharge from a liquid sprayer is enhanced through a turbulent effect created by a ported baffle defining an air plenum into which air is induced to flow into the spray plume as it emerges from the discharge orifice causing the particles to collide and mixing with the emerging spray.  The baffle port is sized to match the divergence angle of the spray plume which essentially fills the port upon entry such that the air in the gap between the orifice and the port is driven through the port by impingement of the spray particles and entrainment of the air into the plume from the gap, while preventing any backflow of air through the port.
