Title: Multiplexed carrier transmission through  harmonic polluted medium
Inventor: PERKINS WILLIAM C
IPC: H04L27/227
Filed: 1980-02-26
Granted: 1982-11-23
Abstract: Abstract of the Disclosure Multiplexed  carrier  signals  modulated  with  digital data are transmitted through a medium  polluted with  har-monic signals  by  asymmetrically positioning the frequen-cy of one of the  carrier  signals between two of the ad-jacent system harmonics, modulating  that carrier signal with digital data at a baud rate so that the spectral density nulls of the modulated  carrier signal  in  the frequency domain coincide with the two adjacent system harmonics  to  which spectral distribution  the  detector response is matched, generating at least one additional carrier  signal whose  frequency  is  also positioned be-tween the two same adjacent system harmonics but is dif-ferent from that of the other carrier signal and whose frequency separation from any adjacent carrier signal is equal to the baud rate or  some multiple  thereof,  and modulating each additional carrier  signal with, digital data at the same baud rate.

Abstract: MEANS AND METHOD FOR THE CONVERSION OF   A CONVENTIONAL CAMERA FROM FULL-FRAME         TO HALF-FRAME FORMAT ABSTRACT OF THE DISCLOSURE Means and a method are disclosed by which a conventional camera can be converted from its usual full-frame format to a half-frame format.  The conversion means comprises a mask removably locatable within the camera body directly forward (i.e. facing the lens rear surface) of the film in the camera, and having a window therein centrally located with respect to that aperture in the camera body defining the full-frame image format.  The mask window is properly sized to provide a half-frame image format, effecting a 50% reduction in the exposed image area, by blocking quarter frame areas of the camera body aperture at either end thereof. The mask is preferably bowed rearwardly against the film's emulsion surface, so as to bias the film against the camera pressure plate.  The conversion means may also include means to apply indicia to a film leader, cooperating with indicia applied to the inside of the camera body, to assure proper indexing of the film through the camera;  means to apply a half-frame reticle to the focusing screen of a view finder assembly;  and audible or physical means to assist in preventing complete rewind of the film leader into the film cassette.  The mask, or the mask and some or all of the above identified elements, may be packaged as a conversion kit.     In use, the mask is mounted in the camera and a roll of film is loaded, having been properly indexed with respect to the camera sprocket.  The film is then advanced in a first pass through the camera, exposing a first set of half-frame image areas on the film, with unexposed half-frame areas located therebetween.  The film is thereafter rewound and reloaded, again properly indexed with respect to the camera sprocket, and advanced in a second pass through the camera exposing a second set of half-frame image areas constituting those alternate unexposed areas.

Abstract: WINDING MECHANISM.        ABSTRACT OF THE DISCLOSURE.     The mechanism for cable winding  comprises a drive means to a spindle carrying a cable reel, having a spur gear the output member of which is axially displaceable in relation to the input member while still permitting torque to be transmitted by the spur gear.   The spur gear applies torque to the spindle via a slippable friction clutch the input member of which is biassed against the output member by axial displacement of a shaft carrying the output member of the spur gear; the shaft displacement being taken up by axial displacement of the output member.   The spur gear is efficient in transmitting torque and avoids difficulties due to under or overheating of the lubricant.   The clutch is a simple but convenient means of transmitting to torque delivered by the spur gear to the spindle.

Abstract: Abstract of the Disclosure A supporting  bearing for the support of a structure such as a bridge or elevated roadway from a supporting pier or embankment has two systems for accommodating misalignment of the bearing with the expected direction of longitudinal move-ment of the structure and/or non-linear movement such as may be obtained with a curved bridge.  These systems may be used alternatively or in addition to one another.  In the first system longitudinal guide means which are provided between two relatively longitudinally-movable plate members of the bearing are resiliently mounted to one of the plate members and accommodate the misalignment or non-linear movement by deformation of the resilient mounting, which preferably comprises strips of resilient material interposed between strips of low-friction material and respective edges of the plate members.  In the second system the bearing comprises two plate members having between them a layer of resilient material which accommodates vertical, horizontal, rotating and tilting forces between the two members; such as a bearing has a layer of low friction material interposed between the layer of resilient material and the plate member which transmits the load to the resilient layer, so as to facilitate movement between them accommodating the said misalignment and non-linear movements.

Abstract: ABSTRACT OF THE DISCLOSURE      A cache system included a storage unit organized into a plurality of levels, each including a number of multiword blocks and a corresponding number of address selection switches and address registers.  Each address selection switch has a plurality of different positions connected to receive address signals from a plurality of address sources.  A decoder circuit generates output signals for controlling the operation of the address selection switches.          In response to previously defined level signals, the decoder circuit conditions a specified one of the number of switches to switch from a first position to a second position.  An address specifying the location into which memory data is to be written is clocked into one address register while the address specifying the location from which an instruction is to be fetched is clocked into the remaining address registers.  A comparator circuit compares signals indicating the level into which memory data is to be written with signals indicating the level from which a next instruction is to be fetched.  The comparator circuit generates signals which cause the delay of instruction access when there is a conflict between writing memory data and accessing instructions.
