Abstract: ABSTRACT         An electromagnetic radiation sensitive copy medium and method for producing positive or negative copies electro-statically.  In a first embodiment the copy medium includes a poled, radiation transmissive, pyroelectric insulative layer, an electrically conductive layer, and a photoconductive layer interposed between and electrically connected with the insulative and conductive layers.  A second embodiment includes two insulative layers, a photoconductive layer that is interposed between the insulative layers, and an electrically conductive layer that is juxtaposed with one of the insulative layers.  A third embodiment is basically similar to the first embodiment except that it includes a plurality of photoconductive layers, each being sensitive to a single, but different, color of light. The method disclosed for producing electrostatic copies with the above embodiments is also employable with prior art copy mediums that have ordinary insulative layers instead of the pyro-electric insulative layers of the present invention.

Abstract: ABSTRACT OF THE DISCLOSURE                 A continuously operating double belt press in which the belts are formed from a plurality of articulated plates and which further includes endless steel bands surrounding and moving with the endless plate belts is provided with a large-diameter drum downstream of each endless plate belt. In addition, the endless steel band surrounding and moving with each endless plate belt is made to surround and move with the large-diameter drum as well. With this design, the compressive pressure exerted by the endless plate belts can be reduced since the large-diameter drums can be utilized to exert additional pressure at higher pressure levels when the material being processed passes out from between the endless plate belts.

Abstract: ANTENNA MOUNT FOR VEHICLES       ABSTRACT        An antenna mount for a vehicle includes an insulated base with an integral internally threaded sleeve defining a central opening in the base and an integral externally threaded antenna connector.  A blind-type clamping assembly threads into a sleeve for anchoring the base to a body panel of a vehicle.           Unlike prior mounts, the clamping assembly has only two sep-arate parts, one of which is a clamp member with an externally threaded stud and integral thin oblong clamping flange at the lower end of the stud.  The other part is a stud nut which is threaded internally and externally and which threads onto the stud and into the sleeve for joining the clamping assembly to the base.  The flange has a maximum thickness which is substan-tially less than its length and width, and the stud joins the flange at a position offset from the geometric center of the flange toward one of its ends to subdivide the flange into two flange portions of unequal length, so as to facilitate entry of the flange through a smaller than usual circular installation hole in the panel of only slightly larger diameter than the stud, and subsequent clamping of the flange against the underside of the panel through progressive threading of the stud nut into the base.  Lead-in conductor cable passages are provided through the flange, stud, nut and base, and the stud nut and stud provide an anchor for the cable within the base.

Abstract: DUAL MODE ELECTROPHOTOGRAPHIC APPARATUS                HAVING DUAL FUNCTION PRINTING BEAM                      Abstract of the Disclosure A dual mode xerographic copier/printer is selec-tively operable to form a latent image of an original document on a photoconductor, or to raster-scan the photo-conductor with a laser printing beam which is under the control of a binary-data-defined image to thereby form a latent image thereof.             The latent image, whether it is formed in the copy mode or the print mode, is toner developed.  The developed image is then transferred to a sheet of copy paper.  This copy paper may be of variable size.             In the copy mode, the laser printing beam is con-trolled to erase the photoconductor bordering that photo-conductor area which will coincide with the sheet during transfer, i.e. bordering the latent image of the original document.             In the print mode, a data processor formats the binary-data-defined image to fit into a photoconductor area compatible with the size of the copy paper.  The resulting electrical signals then control the laser printing beam to erase the entire photoconductor, exclusive of the binary-data-defined image.

Abstract: FAILURE WARNING AND SHUT-OFF FOR ANTI-SKID SYSTEM                ABSTRACT OF THE DISCLOSURE          An improvement is provided for use in a wheeled vehicle having anti-skid circuitry associated with the wheels thereof.  Fundamentally, the invention comprises a comparator connected to the anti-skid circuitry which produces an output signal when anti-skid signals exceed a particular level for a predetermined period of time.  The output of the comparator is operative for removing the application of the anti-skid control circuit from the anti-skid valves and for applying in its place a rudimentary anti-skid control circuit comprising a multivibrator of predetermined duty cycle.  Thus, under all conditions, braking effort remains with the vehicle operator but under certain conditions is modulated at a predetermined rate by the multivibrator.  Provisions are also made for re-turning the anti-skid system to normal operation in conjunction with the brake system when the output of the anti-skid system drops below the aforesaid particular level.
