Granted: 1991-08-20
Abstract: ABSTRACT OF THE DISCLOSURE     An easily assembled clip for clamping papers  has a  pair  of  generally T-shaped clamping  members  each having a clamping portion and two lugs, a pivot pin for interconnecting  pivotally  the lugs  of  the  clamping members,  and a torsion spring mounted on the pivot pin for  biasing  the  clamping portions  of  the  clamping members  to abut against each other.   The  improvement wherein  an  end  of the pivot has two  axially  spaced annular  flanges  between which the  pivot  pin  passes through  a  lug of a clamping member and a lug  of  the other  clamping  member.   The  pair of  lugs  disposed between the flanges are biased by the torsion spring to move in  opposite  directions and  in  turn  to  clamp tightly  the  pivot pin between  the  flanges,  thereby preventing  one of the flanges from outward movement by the obstructing action of the lugs between the flanges.

Movable contact springs move in accordance with the armature in the seesaw movement.  A base is provided with stationary contacts with which movable contacts of the movable contact springs cooperate in the seesaw movement.  The armature ends pass between the projections provided on both sides of the core ends when the armature ends engage or disengage from the core ends.  The relay has a flat configuration thereby reduc-ing the packaging height.

Abstract: ABSTRACT OF THE DISCLOSURE   A bipolar RAM circuit that can be expanded to provide as many ports as desired has separate read and write ports.  Each read port comprises two transistors whose collectors are respectively connected to bit lines for that port and whose emitters are commonly connected to a word line.  Each write port comprises a pair of transistors whose collectors are respectively connected to the data latch within the cell, whose bases are tied to a pair of bit lines and whose emitters are connected in common to a word line for that write port.  To write information into the cell, current is either steered from a standby current path to a desired word line, or a larger write current is steered to the selected word line, causing the data in the cell to be determined by the differential voltage present on the bit lines for the write port.

Abstract: ABSTRACT         A system for interrelating scanner data from a supermarket  checkout  counter  with  demographic  and/or economic data concerning individual customers to generates a demographic and economic analysis or sales with respect to specific supermarket items.   Each customer who wishes to have check cashing privileges at the supermarket provides the  supermarket with certain demographic and/or economic data and is assigned a check cashing code.  Whenever the, individual wishes to pair for groceries by check, the cashier at the checkout counter enters the individual's code into the cash register and the number is stored in a computer. The  computer keeps  track of all  items purchased by the individual, preferably by the entry of item data trough a bar code scanner at the checkout counter.   In return for free or low cost check cashing service,  the supermarket provides the accumulated item data and corresponding check cashing codes to the check cashing company, who then via computer  is  able to  interrelate  the  demographic  and/or economic   information  concerning  individuals  with  the specific  products  being  sold  to  those  individuals,  and provide appropriate marketing reports to manufacturers.

Title: Digital video decompression system
Inventor: KEITH JOHN M
IPC: H04N9/804
Filed: 1988-10-04
Granted: 1993-06-22
Abstract: RCA 84,913 Abstract of the Disclosure A full motion color digital video signal is compressed, formatted for transmission, recorded on compact disc media and decoded at conventional video frame rates. During compression, regions of a frame are individually analyzed to select optimum fill coding methods specific to each region.  Region decoding time estimates are made to optimize compression thresholds.  Region descriptive codes conveying the size and locations of the regions are grouped together in a first segment of a data stream.  Region fill codes conveying pixel amplitude indications for the regions are grouped together according to fill code type and placed in other segments of the data stream.  The data stream segments are individually variable length coded according to their respective statistical distributions and formatted to form data frames.  The number of bytes per frame is dithered by the addition of auxiliary data determined by a reverse frame sequence analysis to provide an average number selected to minimize pauses of the compact disc during playback thereby avoiding unpredictable seek mode latency periods characteristic of compact discs.  A decoder includes a variable length decoder responsive to statistical information in the code stream for separately variable length decoding individual segments of the data stream.  Region location data is derived from region descriptive data and applied with region fill codes to a plurality of region specific decoders selected by detection of the fill code type (e.g., relative, absolute, dyad and DPCM) and decoded region pixels are stored in a bit map for subsequent display.

Abstract: ABSTRACT OF THE DISCLOSURE       A female component of a hook-and-eye fastener is assembled from an eye body and an eyelet. The eye body of a hollow configuration having oppo-site end openings into which a hook body of a male compo-nent is inserted to engage the eye body of the female component, which body is provided with, in its bottom wall: upward-and-inward sloping portions in the opposite end openings; a recessed portion interposed between the sloping portions; and an aperture through which is passed a distal end part of a hollow shank portion of the eyelet.          In assembling of the female component, the distal end part of the shank portion of the eyelet is staked so as to be plastically deformed into an annular curled edge abutting against an inner surface of the bottom wall of the eye body. Since the annular curled edge of the shank portion of the eyelet is entirely received in the recessed portion of the bottom wall of the eye body, it is possible to reduce the overall height of the eye body, which leads to reduction of the overall height of the female component, whereby the fastener is improved in appearance and texture.

Abstract: ABSTRACT         A contactless heating apparatus for thin filaments comprises means to linearly support a length of filament, an induction coil provided adjacent to the filament with its axis substantially parallel to the length of filament, a source of alternating current in the frequency range from HF to UHF con-nected to the coil, and a conducting rod connected to one of the end turns of the induction coil and disposed substantially paral-lel to the length of filament; the arrangement being such that heating of the filament occurs adjacent to the conducting rod.          Preferably the filament is run through a vertical cylindrical chamber in which a reducing atmosphere is maintained; the filament and the coil being located in an induction furnace.  The coil is preferably non-uniform in diameter, the diameter being larger at the end to which the rod is attached and the end of the coil oppo-site to that to which the rod is attached is earthed.  The rod may be shaped such that the separation between rod and filament varies along the length of the rod to thereby vary the temperature pro-file along the heated portion of the filament.  The AC power source used 18 a Class C oscillator valve located in the induction furnace.  This power source is rich in harmonics.
