Abstract: ABSTRACT OF THE DISCLOSURE A copier-printer is employed in conjunction with an optical scanner and associated character recognition logic to transmit information contained in a document over a telephone line or other communication line.  The copier-printer is used to make a copy of the document which is stored in the duplex tray.  When a buffer memory associated with the communication line is ready to receive further information for transmission, the copy is retrieved from the duplex tray and circulated through the copier-printer to the optical scanner.  The scanner provides the information from the copy to the buffer memory in a non-coded format except to the extent that the character recognition logic is able to code some or all of the information.  The copy is ad-vanced from the scanner to a mailbox in the form of a limited access compartment at the bottom of the collator for the copier-printer.  The copier-printer may be used to receive information transmitted over the communication line by temporarily storing the information in the buffer memory and then printing the information on paper which is routed to and stored in the mailbox.  Information provided to the print buffer for printing can be checked for printing accuracy by scanning the resulting printed paper using the optical scanner and comparing the scanned information with the information originally entered in the print buffer.

Abstract: ABSTRACT OF THE DISCLOSURE         Disclosed herein is a device for fitting filters to cigarettes by means of glued jointing bands, in which a peri-perally grooved carrier roller transfers groups of two ciga-rettes aligned axially with the interposition of a filter cut-ting, to a rolling position.    In the region of the said rol-ling position, a counter-rolling element defines, through one of its fixed counter-rolling surfaces and in combination with the cylindrical surface of the said carrier roller, a passage in the region of which the rolling of the bands around the groups of cigarettes takes place.  The said counter-rolling element is provided with at least two counter-rolling sur-faces which, in turn, can be carried into the rolling position. Cleansing means clean the counter-rolling surfaces momentarily not in use for the rolling of the groups of cigarettes.

Abstract: ABSTRACT OF THE DISCLOSURE          An indirect frequency synthesis, microcomputer-controlled tuning system utilizing a frequency stepping process to tune to a selected channel frequency is disclosed.  AFC discriminator information relating to a predetermined frequency range around the correct nominal frequency for the selected channel and the tuning direction toward the nominal frequency is provided to the microcomputer for frequency-stepping the tuner along the AFC discriminator curve in tuning to the selected channel.  Vertical sync verification of the detected carrier signal provides more reliable carrier signal detection with the frequency-stepping procedure resumed upon invalid carrier detection.  If a limit of the tuning range is reached, tuning is immediately switched to the other limit with the frequency-stepping procedure resumed in the original direction following a predetermined system stabilizing period.

Abstract: ABSTRACT           This relates to a portable abrasive throwing wheel device or abrasive blasting device which is utilized for blasting castings and the like to effect the cleaning thereof.  The portable device is of such a construction whereby its total weight is on the order of 100 pounds and is so suspended wherein it has very little thrust reaction on an operator so that it may be readily manipulated.  Further, the principal thrust of the device is carried by the suspension for the device and otherwise is directed towards the operator so that is may be readily counteracted.  The portable device includes a fixed motor and a fixed abrasive supply with a throwing wheel carried by the motor and only a housing portion being movable.  The housing is rotatable about the axis of the motor and serves to permit the discharge opening of the device to be tilted to the desired angle for directing the abrasive blast where desired.  Several abrasive supply systems are provided as are several mountings for the portable device.
