Title: Scrap metal press for producing compacted scrap blocks
Inventor: VEZZANI LUCIANO
IPC: B30B9/32
Filed: 1983-09-19
Granted: 1988-02-11
Abstract: A scrap metal press is disclosed which includes an inclined feeder box, downstream whereof there are provided at least one compacting unit and a guillotine shears unit for the production of compacted scrap blocks. To ensure that a smooth downward movement of the scrap metal can occur even with the feeder box only slightly inclined on a horizontal plane, a plate is provided at the box bottom which is at least temporarily reciprocated with a component in the same direction as the box longitudinal direction. The plate motion, which brings about a condition of dynamic friction between the scrap metal and plate, is preferably accomplished by the use of a slow-motion hydraulic motor having an off-centered pivot pin passed through an opening in the box bottom and engaging pivotally with a body attached to the plate and being loosely movable within the opening.

Title: Graphics display refresh memory architecture offering rapid access speed
Inventor: BRUCE ROBERT ALAN
IPC: G09G1/16
Filed: 1983-02-10
Granted: 1988-09-15
Abstract: A raster graphic refresh memory architecture offering increased access speed. The memory takes advantage of the "page mode" of operation of dynamic random-access memory integrated circuit devices which require two separate device addresses for random access to a storage location therein but permit in "page mode" a first address corresponding to a set of storage locations to be maintained while changing the second address for more rapid access. The memory is organized so that a portion of the second device address is allocated to the least significant bits of one dimension of the display address and another portion of the second device is allocated to the least signficant bits of another dimension of the display address, thereby forming a two-dimensional cell of storage locations on a single page corresponding to a region on the display. The page can be extended by using a plurality of random-access memory devices and selecting one of the devices using the least significant bits of one dimension of the display address. An addressing scheme is provided which permits simultaneous "page mode" writing of data into multiple storage locations representing contiguous pixels of the display. A mechanism is also provided for reading back data from a plurality of storage locations representing contiguous pixels on the display and storing the data in a temporary storage-shift register for subsequent manipulation.

Abstract: The essential part of an adjustable choke for compressed air and other fluids is made up of two relatively turning disks of which one has a calibrated channel in it running round the axis of the disks. By relative turning of the disks the fluid is caused to flow along different lengths of the channel in keeping with the desired choking action. The two disks are mounted within a housing, with a spring keeping them pressed together. The housing has a bell-like cover in which one of the disks is keyed and sealed at the disk's outer edge with the spring between it and the top of the cover in a chamber. The other disk is mounted on a base of the housing. There is a central pillar in the housing that joins the cover to the base and contains a duct by which is supplied into the chamber through a hole in the one disk, into the channel, through the other disk and then out through the base of the housing. The cover may be turned for turning the one disk in relation to the other.

Abstract: A backpack having a front panel normally riding on the back of the wearer according to this invention has a front panel which is vertically elongated and which is formed of an at least semirigid shell having a shape generally complementary to that of the back of the wearer and constucted to be relatively bendable longitudinally and relatively stiff transversely. Thus the panel can bend forward and back, that is about a horizontal axis, but cannot flex about a vertical axis. This is achieved by forming the shell with transverse rigidifying formations so it is longitudinally relatively bendable and transversely relatively stiff. These formations according to this invention are ridges or grooves.
