Abstract: A SIMPLIFIED LINE SWITCH FOR A TELEPHONE SET          Abstract of the Disclosure A line switch assembly for a telephone switch has a unitary switch having a base within which are cantilevered contacts and a cap over the base, the cap having cam formations which actuate the contacts on reciprocal movement of the cap.  An actuating member rests on the cap and has an extension with a rib which extends up into a recess in the top housing of the telephone set, the recess being one which accepts one of the handset transducers.  Pressure on the rib pivots the actuating member and depresses the cap.  The switch is a preassembled unit and is normally mounted on a circuit board carrying other components.  A reduced number of components and quicker and easier assembly give a relatively high cost reduction.

Abstract: ABSTRACT OF THE DISCLOSURE          For a document sheet feeding and registration apparatus and method for deskewing and registering a document sheet relative to a regis-tered copying position on a copier platen by feeding it against a sheet aligning document registration member, there is disclosed apparatus for initially feeding the document sheet towards the registration means with a first document sheet feeder exemplified by a widely transversely spaced pair of high friction sheet feeding rollers, which resist skewing of the document sheet, and removing the first document sheet feeder from the document sheet after its lead edge is engaged by a second document sheet feeder and before the document sheet engages the registration edge stop so that final skewing control of the document sheet is only by the second document sheet feeder, this second document sheet feeder being a single sheet feeding roller posi-tioned centrally of the document sheet lead edge area and positioned closely adjacent the registration edge. This single roller provides a brief low rotational resistance deskewing of the document sheet while driving the document sheet into final alignment with the registration member. All of the sheet feeding rollers are positioned over the document on the platen extending through a backing plate so as to be hidden during copying.

Abstract: ABSTRACT OF THE DISCLOSURE         The invention is a multi-channel position detec-tion system which utilizes several separate emitters and a single photodetector to, for example, align a multi-lead component manipulator with a predetermined location in a printed circuit board.  An oscillator circuit generates a modulated signal for each emitter and a multiplier circuit develops an output signal based upon the oscillator output and the photodetector output.  The photodetector provides an output responsive to the emitter signal as attenuated by the circuit board location relative to the emitter.  When the lead hole of the circuit board is aligned with the emitter and photodetector minimum attenuation of the signal occurs.

Abstract: SINGLE LIP ROTARY DIE            ABSTRACT   Disclosed is a single lip tubular extrusion die in which a plurality of separate melt streams passing through respective annular flow paths are fed to a common annular flow passage extending axially to and terminating at a die orifice.  The annular flow passage is connected to the annular flow paths through respective groups of holes spaced annularly about the die axis. Each group of holes has its openings to the common annular flow passage spaced a different radial distance from the die axis to allow the separate melt streams to be layered in the common annular flow passage and co-extruded.  One of the die lips is rotatable so that each melt stream produces a uniform layer of polymer in the extruded film while imparting a molecular orientation to the extruded film in the transverse direction (TD).  An extruder-type seal may De provided adjacent a gap between a rotating and stationary part of the die to force melt attempting to penetrate the gap into the annular flow passage.

Abstract: ABSTRACT OF THE DISCLOSURE An extruder for delivering foamed glue from a foamer selectively to a plurality of spaced apart outlet orifices for extrusion onto a substrate surface and to bypass passageways for diverting the foamed glue to a defoamer for subsequent return to the foamer, is formed of three elongated flat blocks secured together releasably in face-abutting relationship.  The surfaces of the outer, inlet and bypass blocks facing the center coupling block are recessed to provide a plurality of passageways all of which extend substantially equal distances from inlet and bypass ports in the inlet and bypass blocks, respectively, to a plurality of coupling ports in the coupling block. An air pressure operated selecter valve in the bypass block is operable to communicate the coupling ports selectively with the bypass passageways for bypassing foamed glue to the defoamer and with the outlet orifices for extruding foamed liquids onto a substrate surface.

Abstract: ABSTRACT Disclosed is a pipe repair clamp which can be installed on a pipe by one person and can be initially installed in a semi-closed position beside a leak and then slid over the leak for final tightening.  The clamp comprises a metal band adapted to be wrapped around a pipe over a suitable gasket.  The longitudinal edges of the band are secured to lug bars, one having fingers secured to it and the other having threaded bolts secured to it.  The free ends of the bolts are each provided with a nut and washer soldered together to form a nut/washer combination.  Each finger is generally U-shaped including a base portion and two leg portions.  The bottom edges of the legs adjacent their free ends are welded to a lug bar.  The legs converge over a part of their length from a first spacing in the region of the base portion sufficient to accommodate a nut/washer to a second spacing in the region of the lug bar sufficient to accommodate a bolt but not a nut/washer.  The top edges of the converging parts of the legs slope outwardly with respect to the bottom edges. The legs have flat ends to accommodate a nut/washer and tabs adjacent the top edges restrain the nut/washer against outward movement while the nut is tightened.  During initial closing of the clamp, the legs guide the nut/washer to keep the bolt properly aligned.  After the nuts are tightened to a pre-determined torque, the solder joints between the nuts and washers break and the nuts are then tightened to a higher torque with the solder acting as a low friction anti-gall surface between the nuts and washers.

Abstract: Abstract A CRT calibration system is provided having a CRT with a display screen, an electron gun system, and a plurality of feedback elements.  Each feedback element has an active area disposed proximately to the display screen at a preselected location such that an electron beam from the electron gun system can strike at least a portion of  the active area.   In  response to being struck by electrons, each feedback element provides a feedback signal related to the area of  the portion struck.  The system also includes a detector system for detecting  each  feedback  signal,  and  an  integrating analog-to-analog converter which, in response, provides a digital signal related to the portion of the active area struck and thereby to the position of the electron beam  relative  to  the  particular  feedback  element interrogated.   Also included is a control system for directing the electron beam to strike a sequence of portions of the active area for each feedback element, thereby evoking a corresponding sequence of feedback signals for each feedback element and a corresponding sequence  of  digital  signals,  enabling  the  control system  to  determine  the  location  of  each  feedback element.
