Abstract: ABSTRACT            A gear selector means for use with a transmission having a main change speed gear set (X) and one or more associated range change gear sets (Y, Z).  The selector means includes a selector member (50) which is movable to a number of posi-tions (1, 2, 3, 4) for the selection of a number of change speed ratios of the transmission and which has a neutral position or series of positions (n) corresponding to a neu-tral condition of the transmission.  The selector member is movable from the or a neutral position (n) to an "up" posi-tion (52) in which upward range changes can be made in a predetermined sequence (A, B, C, D) and to a "down" position (53) in which downward range changes can be made in a pre-determined sequence, each movement of the selector member to the "up" or "down" position being arranged to change the operative range of the transmission either up or down to the next range in the predetermined sequence.

Title: Peak load access in a two-way catv contention system
Inventor: CITTA RICHARD W
IPC: H04N7/173
Filed: 1984-11-07
Granted: 1986-08-12
Abstract: Abstract of the Disclosure In a two-way cable television (CATV) contention system peak upstream loading is accommodated by varying the length of the upstream transmission window during which a subscriber may randomly transmit for improved subscriber access to the CATV headend.  Following an upstream transmissioin, the subscriber waits a predetermined period for a message receipt acknowledgment from the headend.          Failure to receive this acknowledgment results in an upstream retransmission by the subscriber at a randomly selected time within a transmission window, the length of which is a function of the upstream message traffic load.          The transmission window is initially short to permit rapid retransmissions upstream in order to avoid interfering noise bursts of short duration.  The upstream transmission window is then increased in length to a maximum value to string out upstream transmissions during a peak access period for reducing upstream message collisions.  Following upstream transmissions during the maximum transmission window, the window is then reduced in length to accommodate reduced upstream traffic following successful upstream communication by the majority of subscribers.  This upstream transmission distribution arrangement improves subscriber headend access, namely system throughput, by increasing the transmission window during periods of peak access and shortening the window length following peak access periods in order to reduce the time required for a successful upstream transmission.

Abstract: ABSTRACT                MECHANICAL STAND UP DOLL           A motor driven doll (20) that rises from a face-down prone position to an erect standing position.  Cam followers drive first one leg (26) from an extended position behind the torso of the doll to a more forward position and then similarly drive the other leg (27) to bring the doll to a splayed leg crouching position.  Thereafter, simultaneous movement of the cam followers rotate the torso (24) relative to both of the legs at the same time to raise the doll to an erect standing position.  As the second leg is being moved from the rearward extended position, a third cam drive (150, 212) pivots the head (34) rearwardly to shift the center of gravity and assist in raising the doll.   As the doll reaches a fully erect position the head is driven to a forward position and, at the same time, a fourth drive (228, 234) effects a swiveling of the head so that the doll displays a pert glance of accomplishment.

Abstract: ABSTRACT        A method for producing printing cylinders for seamless or endless patterns with printing form engraving machines having a scan cylinder and an engraving cylinder.          A pattern original on the scan cylinder is opto-electronically scanned picture-element-wise along scan lines lying next to one another which run in a circumferential direction of the scan cylinder, and where every scan line supplies the information for an engraving line of a pattern repeat to be transmitted onto the printing cylinder.  The scan original is longer than the pattern repeat (original extension).  In a mixing region, picture elements of the original extension and of the beginning of the original stored for every scan line are combined in accordance with a prescribed mixing function to form picture elements having a new density information. For engraving of the printing cylinder, the overall repeat is formed from the picture elements deriving from this mixing and the unaltered picture elements following from the end of the mixing region up to the end of the pattern repeat of the lines.
