Filed: 1986-03-18
Granted: 1991-03-26
Abstract: A B S T R A C T     A process for production of metallurgical composites comprises the steps: (a) subjecting brown coal to shearing forces to produce a plastic mass; (b) admixing finely divided ore and/or concentrate with the coal either during or after step (a); (c) compacting the mixture produced in step (b) to produce a compacted mass; and (d) drying the compacted mass to produce the metallurgical composite.   Step (c) is preferably effected by extrusion.  The invention also provides a smelting process in which the composite is heated to a temperature at which the ore or concentrate is reduced to metal.

Title: Reinforced blister package
Inventor: FISHER BRIAN A
IPC: B65D81/00
Filed: 1987-04-22
Granted: 1991-07-16
Abstract: ABSTRACT     The invention provides a package having a transparent blister defining a main cavity and a peripheral flange lying in a plane about the cavity.  A substrate is attached to the blister so as to close the cavity with the product lying between the blister and the substrate.  The cavity is divided by at least one fold in the blister into a primary pocket containing the product and at least one secondary pocket which is empty to form a shock absorbing structure.  Damage to the blister in the area where the product rests against the blister caused by impacts of the product on the blister walls are minimized by the resilience of the shock-absorbing structure which effectively provides a minimum of three layers of blister material to be penetrated before the product can protrude from the package.

Granted: 1991-06-11
Abstract: ABSTRACT            An agricultural roller has two or more pivotably connected sections arranged side by side.  A central frame has a tow-ing bar pivotably connected to the central frame.  The rol-ler has roller sections (4, 6) on either side of the cen-tral frame (8) and transport wheels (15, 16), which are settable between an inactive position above the ground in the work position of the roller and a transport position where the roller means are lifted up from the ground and swung towards each other to achieve a small transport width.            The two side sections (4, 6) situated closest the central frame (8) carry the transport wheels connected to the sec-tion frames, and between the sections there are pivot joints (17, 18) implemented such that the sections can ad-just themselves to irregularities in the ground in the working position of the roller.  A hydraulic cylinder (21) is arranged between -the towing bar (2) and central frame (8), and can swing the central frame and the roller sections (4, 5,6) connected thereto about 90° about a pivoting axis trans-verse the driving direction to an  "on edge"  or intermediate position,where the roller rests on the trans-port wheels (15, 16).  By driving the tractor forwards the side sections (4, 6) are caused to swing towards each other into the transport position.

Abstract: SHEARBAR ATTACHMENT AND ADJUSTMENT APPARATUS AND METHOD              ABSTRACT OF THE DISCLOSURE A shearbar attachment and adjustment apparatus is adapted to apply clamping forces to a shearbar in a forage harvester at first locations on opposite ends of the shearbar. The clamping forces prevent the shearbar from backing away from a rotary cutterhead in the forage harvester during chopping of crop material by passing cutting edges of knives on the periphery of the cutterhead close to the cutting edge of the shearbar.  Also, the apparatus is adjustable to apply pulling forces on the shearbar at second locations on its opposite ends which are offset inwardly from the first locations.  Application of pulling forces at these inward locations relative to the outward locations of the clamping forces tends to compensate for the effect of the convex shape of the shearbar cutting edge by causing bowing of the shearbar at the second locations to provide a more uniform clearance between the cutting edge of the shearbar and the cutting edges of the cutterhead knives.

Abstract: DOOR MOUNTED IRONING BOARD ASSEMBLY            Abstract An ironing board assembly (10) for mounting on a standard door (D) in the home or the like includes a tubular mounting frame (11), a pivoted ironing board (12) on the frame and, if desired, a swinging cover (16) for enclosing the board and frame when not in use.  The frame (11) is supported by at least one hanger bracket (15) extending over the top of the door.  The bracket (15) includes an inverted U-shaped hook (20) and a second hook (21) extending in the opposite direction.  A coupler section (22) in between provides a small included angle of approximately 6° between the hooks for pre-biasing the assembly so as to maintain it snug against the door during movement.  A bent prong (24) rotatably fixes the second hook (21) to the frame (11).  The ironing board (12) is supported in the horizontal operative position by a U-shaped support brace (30).  One of the pivot pins (31a) mounting the brace (30) is flexible and engages a detent means for holding the board (12) in the retracted position. A tab (40) with a cam portion (40a) forms the detent means on the board frame and provides snap action retention when the board is raised.  A plastic stop (45) on the board frame provides resiliency to absorb shock as the board moves to the operative position.  The hinges (55) that support the auxiliary swinging cover (16) include a mounting block (S) and a hinge rod (56) that are interchangeable for the top and bottom.  The block (S) for the hinge also serves as a spacer for the frame against the door.  Suction cups (53) mounted on the frame (11) lock onto the door and serve to assist in securing the assembly against lateral movement across the door.
