Abstract: ABSTRACT OF THE DISCLOSURE              A device for photogrammetric evaluation of stereo-couples of photographs which are scanned light electrically and, in order to obtain height coordinate values, are evaluated by correlation.            The device is particularly useful in the evaluation of aerial photographs.  To reduce correlation errors due to interfering signals obtained from different correlation signal channels and, hence, to increase the precision of a correlation operation, at one time only the informations from one correlator signal channel in each of the two scanning channels are exploited to obtain the informations from the scanned stereo-pair of photographs.  Therefore, it is desirable that, in the course of the correlation operation, the highly resolving correlator signal channels are predominantly and for a considerable long time employed to correlate the information.   According to the invention gate circuits are inserted between the correlator signal channels and the discriminator.            The signal channels are successively triggered via the gates by operation of a pulse distributor connected to a clock pulse generator in a sequence of the rising resolution of said channels.

Abstract: ROUTE CONTROL SYSTEM FOR RAILROAD INTERLOCKINGS                ABSTRACT OF THE DISCLOSURE     A route oriented interlocking control system with only entrance, exit, and alternate route selectors on the control machine console.  No track switch controllers or indications are provided at the control location.  Operation of entrance and exit selectors in sequence establishes desired route storage within the control machine, after the absence of any conflicting route and the non-occupancy of involved track sections are checked.  This route control is then transmitted to the field location to select the field route relay, position the track switches, and clear the proper wayside movement indicator to authorize train movement through the route when all switches are positioned and the track within the interlock-ing is unoccupied.  Indications of the registry of the route control and operation of the movement indicator are returned to the office display console.  Route release occurs by sec-ondary circuit controllers when the train occupies the final track section.          This sectional release allows the selection and storage of route information for any route not conflicting with the initial portion of the released route when cleared by the train.  Selection of an alternate or run-around route is made by operation of single device designating that alternate route prior to the operation of the entrance and exit devices for the basic route.  Improper operation of the control machine results in the cancellation by primary and secondary circuit controllers of all route information storage and no route is aligned.

Abstract: ABSTRACT OF THE DISCLOSURE           .         A surgical blade dispenser is provided herein.  It includes a box for storing blades in such position that a scalpel handle can be in-serted through an aperture in one wall of the box, lockingly to engage one blade and to remove it from the box through the aperture.  The blades are individually positioned and supported within the box such that apertures in the shank portion of the blade are engagable with a mating boss on the forward end of the scalpel handle as the handle is inserted through an aperture in the wall of the box.  Further insertion of the handle causes the boss fully to engage the aperture in the scalpel blade and, once complete engagement has been attained, the blade is withdrawn from the bos by withdrawal of the handle through the paerture.  A blade disposal section is preferably included in the box.  The handle aperture of the blade disposal section is provided with a metal edge.  When a scalpel handle with a blade mounted thereon is inserted through the aperture, the rear edge of the blade can be engaged with the metal edge of the aperture and withdrawal of the handle strips the blade from the engaging boss, leaving the blade within the disposal section as the handle is withdrawn through the aperture. Thus, the blade is engaged with the handle while avoiding possible safety or contamination problems.        -i-
