Abstract: MAKING COPLANAR LAYERS OF THIN FILMS                       ABSTRACT    A method for forming coplanar thin films, particularly conductor-insulator patterns, on a substrate.  A pattern which includes a first thin film and an expendable material deposited thereon is formed on the substrate.  The expendable material is selected so that it can be selectively removed by an etchant which does not attack the first thin film or an insulator which is to be deposited.  The second thin film is deposited by RF sputtering at a bias which is sufficiently high to cause sub-stantial reemission of the second film.  This results in the covering of the exposed substrate surfaces and the upper surface of the material with the second film but leaving the side sur-faces of the material exposed.  The expendable material is then chemically etched so as to lift-off both the material and the second film deposited thereon, thereby leaving a coplanar pat-tern of first and second thin films.

Abstract: A printing press with means for transferring the printing ink electrostatically onto a dielectric web.                 ABSTRACT OF THE DISCLOSURE According to the present invention an electrostatic charge is in-duced on the surface of the impression cylinder of a printing press by means of an inductor device.  The inductor device includes a row of pointed elec-trodes.  Cover elements are fitted to the inductor device and can be displaced along the row of electrodes, thus insulating a certain part of the electrode array.  As a result, only a given, restricted area of the impression cylinder surface is charged.  In addition, an insulating shield is fitted at each end of the impression cylinder to prevent charge leaking away from the impression cylinder surface to the earthed shaft of the impression cylinder.  These no-vel measures enable the charge distribution in the impression zone to be precisely controlled.  This is of particular advantage when printing onto webs whose width is less than that of the impression or printing cylinder.

A switch-actuating member formed of relatively thin, flexible insulating material is in facing relationship with the insulator sheet and has switch-actuating protrusions thereon respectively in alignment with the switch elements and extending toward and contacting the insulator sheet.  The actuating member also has isolator pro-trusions thereon intermediate the switch-actuating protrusions and respectively in alignment with the spaces between the dome elements and extending toward the insulator sheet.  A flat key-board member also formed of relatively thin, flexible material has one side in facing relationship with the actuator member and has keyboard indicia on its other side respectively in alignment with the switch-actuating protrusions and the switch elements.  The board, insulator sheet, actuating member and keyboard member are held in assembled relation with the insu-lator sheet and actuator member sandwiched between the board and the keyboard member so that deflection of the keyboard member in the region of a particular indicia in response to force manually exerted thereon causes the respective switch-actuating protrusion to actuate the respective switch element through the insulator sheet, force exerted on the keyboard member at a particular indicia being isolated by the isolator pro-trusions from the dome elements aligned with other indicia.

Abstract: SIGNAL CONDITIONING CIRCUIT FOR MAGNETIC SENSING MEANS          ABSTRACT OF THE DISCLOSURE           A signal conditioning circuit for the output of a magnetic position sensor is disclosed.  The magnetic sensor generates a total output signal that increases as a function of the rotational velocity of the sensor with a spurious noise component that is a relatively constant percentage of the actual signal voltage over the speed range.  In a preferred embodiment, the signal conditioning circuit discriminates between the noise component and the signal component by com-paring the total signal to a variable threshold only after a positive going zero cross.  The variable threshold is generated as a function of the peak amplitude of the total signal.  In a second embodiment the signal conditioning circuit includes gain control means which varies the amplitude of the total input signal as a function of its peak to maintain the thres-hold above the noise component.

Abstract: 1950-99a ABSTRACT OF THE DISCLOSURE         The outermost sheet of a stack of overlapping sheets in a magazine is partially separated from the neighboring sheet of the stack by the peripheral projection of a singularizing roller which is adjacent to the rear edge face of the outermost sheet.       The projection engages and moves the rear edge face forwardly while the outermost sheet is biased against an abutment in the region of its front edge face.  The bias upon the outermost sheet is relaxed or terminated when the rear portion of the outermost sheet is flexed away from the neighboring sheet so that the outermost sheet can be withdrawn from the magazine, either forwardly or rearwardly, by advancing rolls which are installed in close proximity of the singularizing roller, in the interior of the roller, or close to the front edge face of the outermost sheet of the stack.  The bias upon the outermost sheet is terminated in automatic response to rotation of the singularizing roller through an angle which suffices to insure separation of the rear portion of such outermost sheet from the neighboring sheet.  If the stack is held in upright position, the outermost sheet can be allowed to leave the magazine by gravity by descending through a slot in the singularizing roller.  In the slot constitutes a pocket, the singularizing roller can be used to invert successive outermost sheets and to deposit the inverted sheets onto a belt conveyor.

Abstract: ABSTRACT OF THE DISCLOSURE     A fluid-bed furnace has at least one combustion chamber, preferably two side-by-side, housing a bed of incombustible particulate material to be fluidised when burning fuel fed thereto.  Bed fluidisation is by forced release in the incombustible material of combustion promoting gas, normally air, from a plenum chamber arrangement externally of the bed proper at a side or end thereof to save overall height.  Other features include the return of used exhaust gas to the bed for additional fluidising and heating purposes; release within the bed of such returned exhaust gas at a position higher than normal conbustion promoting gas; an auxiliary burner within the combustion chamber to consume fine fuel material lifted from the bed in operation; insulation of at least the normal combustion promoting gas plenum chamber externally by incombustible bed material and/or internally by refractory lining; end tapering of bed traversing gas feed pipes to reduce expansion resistance; and a removable end plug in the latter pipes to ease cleaning thereof.
