Abstract: SPACECRAFT WITH MODULATED THRUST ELECTROSTATIC       ION THRUSTER AND ASSOCIATED METHOD                 ABSTRACT OF THE DISCLOSURE An axial electrostatic ion thruster (10) for use on a dual-spin stabilized spacecraft (70) is disclosed. The thruster (10) is mounted on the spun portion (72) of the spacecraft (70) and continuously fired for an integral number of spin periods to provide north-south velocity and attitude control.  To achieve zero attitude precession with a statically imbalanced despun platform (74) or an intentional attitude precession generally, the ion thrust is spin-synchronously varied between two non-zero levels to achieve a prescribed Fourier component amplitude and phase at the spin frequency.  Modulation of the thrust is achieved with constant ion beam current by complementary modulation of the beam voltage, VB, and accel voltage, VA by varying the ion extraction system grid voltages.  This varies the thrust while maintaining a constant total accelerating voltage VTOT = VB + ¦VA¦.

Abstract: PLASTIC CONTAINER AND METHOD OF FABRICATING SAME          Abstract of the Disclosure A nestable plastic trash container having integrally bonded upper and lower plastic lifter bar members to be adapted for automated dumping operation by conventional semi-automatic dumping apparatus is fabricated by initially preforming the lifter bar members by blow molding, inserting the preformed lifter bar members into respective recesses in another blow mold apparatus for forming the main body of the container, and then blow molding the main container body while simultaneously bonding it to the preformed lifter bar members. The insert-receiving recesses of the container body blow mold apparatus and the preformed-lifter bar members respectively have compatible end-to-end convex arcuate surfaces which abut in sealing relation during the blow molding of the container body to prevent escape of the plastic material into the insert-receiving recesses. The bonding surfaces of the preformed insert bar members are similarly convexly arcuate to direct the plastic material of the container body to expand uniformly about the bonding surfaces for bonding thereto of a generally consistent wall thickness of the main container body.

Abstract: 42489 CAN lA     Flexible Filter Bag and Method Of Fabrication ABSTRACT           A flexible filter bag, the filter element of which is seamless and avoids prior leakage problems, is made by wrapping a flexible, preferably perforated, filtering fabric and a flexible nonfiltering transport material together onto a cylindrical mandrel to provide a tube.  A thin metal ring is fitted into the tube, and the portion of the filtering fabric which extends beyond the edge of the transport material is folded inwardly around the ring to provide a cuff.  A sleeve of a length about twice that of the tube is inserted into and pulled over the tube until the free ends of the sleeve are approximately coterminous with the ring-free end of the tube.  The free ends of the sleeve and tube are gathered in the manner of a sausage casing and then subjected to pressure to form a seal, but the convolutions of the transport material terminate just short of the seal so as to avoid bunching at the seal.

Abstract: ABSTRACT OF THE DISCLOSURE    A method and apparatus for placing a ferrite core in the slot of a pad of a ferrite head.  A circular magnet is mounted below a non magnetic table on a slider slidable along a line.  The pad is clamped on the table with its slot exposed and aligned along the line and the center of the magnet.  When the ferrite core is placed on the table near the magnet, it stands on edge, aligned along a radial line of flux from the magnet.  As the magnet is slid towards the slot, the core follows the center of the magnet,  aligned along the centerline of the slot following the radial line of flux.   The core slides into the slot and is thereafter bonded to the pad.

Title: Damage resistant reflective textured surface system

Granted: 1992-07-07
Abstract: DAMAGE RESISTANT REFLECTIVE TEXTURED SURFACE SYSTEM     Abstract of the Disclosure A scar-resistant decorative wall panel has a mirror surface overlaid by a substantially coarse-mesh,  common weave wire  screen giving a peek-through changing-with-angle  view  of  the  mirror  surface.    Viewed  at  the perpendicular  to  it,  the  mirror  surface  gives  a substantial-area reflection of the viewer that may be as much as 30 to 50% of the mirror surface.  At angles from the perpendicular increasingly approaching 45 degrees, the view of the mirror surface progressively diminishes for two  reasons:   (1)  the  weave  of  the  mesh  blocks progressively more of the view of the mirror surface and (2) the reflection of the back surface of the mesh appears to  occupy  increasing  areas  of  this  mirror  surface, decreasing in this way the view of this mirror surface. Both these phenomena act together in a tendency to hide and confuse to a casual viewer defacement of the mirror surface,  and  the  substantially  vandal-proof  overlying coarse-mesh screen at the same time protects the mirror surface from broad-area-contact type scarring.

Abstract: Abstract of the Disclosure A PNEUMATIC TIRE      A pneumatic tire (10) having a tread (12), carcass (70), sidewalls (14), bead portions (18) and an annular reinforcing structure or belt structure (76). The tread (12) has two different types of circumferential grooves.  Two circumferential straight grooves (20) divide the tire into three circumferentially extending portions (24,26,28).  Each portion is further divided by a circumferentially extending zig-zag groove (22) or an "S" shaped groove.  Each portion is then divided into blocks (30) by a plurality of axially extending grooves (32).  The tread-reinforcing structure (76) has two belt plies (78,80) of steel cords (82), the cords of one are oriented at an angle A, with respect to the mid-circumferential centerplane (MC), while the cords of the other are oriented at an angle B, where angle B is less than angle A.

Title: Culinary mixes for products prepared from batters and  doughs with fish oils stabilized with fructose
Inventor: SCHROEDER LISA R
IPC: A21D2/34
Filed: 1989-01-25
Granted: 1996-01-02
Abstract: Disclosed are food products, especially culinary mixes and baked goods prepared therefrom which contain nonhydrogenated fish oil yet which exhibit enhanced stability of the fish oil against flavor and aroma degradation. The improved food products are stabilized by the incorporation of the food product such that the weight ratio of fructose to fish oil is at least about 0.05:1.  Surprisingly, incorporation of modest amounts of fructose in food products within the indicated minimum provides a stabilizing effect of the highly unstable fish oil.  The present invention finds particular suitability for use in connection with fish oils rich in omega-3 fatty acids.

Title: Brake control valve with caged tare pressure spring
Inventor: LATVALA BRUCE E
IPC: B60T11/12
Filed: 1989-04-25
Granted: 1993-02-02
Abstract: ABSTRACT OF THE DISCLOSURE A proportioning control valve for heavy duty fluid pressure braking system includes a proportioning piston which is normally held in engagement with an abutment by control pressure.  A tare pressure spring urges a caging member into engagement with a stop which is spaced a predetermined distance from the end of the proportioning piston, which is less than the distance between the valve engaging member carried by the proportioning piston in the proportioning valve member. Upon loss of pressure at the control pressure port, the proportioning piston is urged toward the caging member. The proportioning piston moves between the gap defined between the end of the proportioning piston and the caging member without opposition from the tare pressure spring, thereby permitting the full force of fluid pressure to break seal friction between the seals carried by the proportioning piston and the wall of the housing.
