Patent EP-0192985-A3 (EP)
IPC: B41J11/26
Filed: 1986-01-30
Abstract: A drive mechanism having a sprocket and a belt with 
inter-engaging lugs and receptacles on the belt and sprocket, 
respectively, wherein orthographic motion is obtained of the 
lugs into and out of the receptacles so as to provide for 
smooth, high efficiency transmission of drive forces by 
providing a fulcrum at inter-pitch spacing positions about 
which the belt bends along a radius centered at the fulcrum 
to bring the lugs directly into registry with the receptacles in 
the sprocket. The system provides virtual sprocket teeth, 
thereby effectively doubling or multiplying the number of 
teeth on the sprocket, compared to lugs on the belt so that a 
small, low-inertia, sprocket-belt drive system effectively 
provides the smoothness of transmission of a system with 
twice or greater the number of sprocket teeth than lugs, but 
without the cost of such additional teeth and lugs and 
without sacrificing belt life due to additional flexures of the 
belt. The drive system is embodied in a web feed tractor 
wherein the belt has pins which enter into and engage 
perforations in a web for feeding the web. The fulcrums also 
locate the belt so as to accommodate the difference between 
the pitch of the belt lugs and the pitch of the sprocket teeth. 
The fulcrums also accommodate the arch in the belt when 
located on the sprocket due to the flexure of the belt about 
the edges of the lugs thereby providing for uniform registra­
tion of the drive system and spacing of lines printed on the 
web (paper) of a printer equipped with a tractor drive using 
the system.

Title: Video display system for wide and standard aspect ratio video signals
IPC: H04N5/46
Filed: 1986-08-26
Abstract: A video display system for displaying a wide screen image having an aspect ratio, such as 5:3, greater than the standard, such as 4:3, aspect ratio of the images represented by conventional television video signals, is arranged for displaying such an image of standard aspect ratio without changing the width of the normal wide aspect raster of the display system. To this end the display system includes a signal processor which, in response to a video signal representative of a standard aspect ratio image, produces, for driving the wide aspect ratio display, a processed video signal the line periods of which each include not only the line synchronizing interval and active video interval but also a delay interval ('PAUSE') the effect of which is to determine the position of the displayed standard aspect ratio image within the width of the wide aspect ratio raster.

IPC: H04B1/713
Filed: 1987-05-21
Abstract: A frequency-hopping datalink for providing communica­
tion between a base station, relay unit and multiple remote 
units utilizes time-division multiplexing and transmits informa­
tion signals containing information relevant to the next fre­
quencies of transmission. Signals from the base station are 
transmitted on a first frequency to a relay unit which retrans­
mits the signals on a second frequency to a group of remote 
units. The information signal from the base station contains in­
formation concerning the frequencies of the next transmission 
and the time slot allotted for the remote units to respond. The 
remote units respond back at the first frequency which is re­
ceived by the relay unit and rebroadcast to the base station at 
the second frequency. The first and second frequencies are 
changed after each message in accordance with a pseudo-ran­
dom sequence generated either at the base station (and trans­
mitted in encrypted form) or by means of a pseudo-random se­
quence generated at each remote unit and the relay unit, whose 
initial state is reset by an internal or externally derived time 
reference and whose pattern is determined by an internal key.

Title: Chuck for tools
IPC: B23B31/12
Filed: 1987-06-09
Abstract: A chuck for receiving and holding the shank of a drilling tool includes a chuck member with a central bore. An anvil for transmitting axially directed percussive force extends into a rear end of the central bore. Clamping jaws are movable in guide channels formed in the chuck member extending into the central bore ahead of the anvil for frictionally locking the shank. In the region of the chuck member into which the anvil is located, there is a radially extending passageway through the chuck member extending between the central bore and a guide channel. A retaining member is radially displaceable through the passageway and has a dimension so that it can project outwardly or inwardly from the passageway. When the remaining member extends radially inwardly from the passageway, it can seat within an annular groove in the anvil and hold the anvil in a position so that it does not transmit percussive force. If the retaining member extends radially outwardly from the passageway, it can seat within a groove in a clamping jaw and secure the clamping jaw out of frictional contact with the shank.
