Abstract: ROTARY SELECTOR SWITCH                 ABSTRACT OF THE DISCLOSURE     A multicircuit rotary selector switch having no external terminals is disclosed.  A two-part interlocking housing journals a user-rotatable shaft carrying a stack of coaxially oriented, multilobed cam discs, each disc defining a tier level within the housing.  Engageable with each disc and lying in its tier level is a pair of elongated movable switching elements each having a wire gripping end portion, a moving contact end portion, and an intermediate cam follower portion riding the lobes of its associated cam disc, each movable switching element being configured as a third class lever.  One or more fixed switching elements, each including a contact portion and a wire gripping portion, are located adjacent the contact end portions of each of the moving switching elements.  Portions of the fixed and movable switching elements are sandwiched between the two parts of the housing to maintain them in proper position relative to each other and to the cam disc stack.

Abstract: ELECTROSTATIC CHARGE DIFFERENTIAL AMPLIFICATION (CDA) Abstract of the Disclosure A method for amplifying an electrostatic, charge-differential pattern is disclosed.  The method comprises (a) imagewise forming a first toner deposit by developing a first electrostatic pattern having a first charge differential per unit area whose maximum value is no greater than a preselected level, (b) in an image-amplification element comprising a charge holding surface layer overlying a field-supporting electrode, forming a current-carrying path between the toner deposit and the field-supporting electrode, (c) under conditions in which nontoned regions are not photoexcited, overall charging the image-amplification element with sufficient charge to form an enhanced electrostatic charge pattern having a second charge differential per unit area whose maxi-mum value is greater than the preselected value in step (a), and (d) developing the enhanced charge pat-tern into a second toner deposit.  By this process, high-maximum-density, continuous-tone images can be produced wherein the maximum density of such images is obtained by amplification of initial charge dif-ferentials whose maximum value is, for example, 30 nanocoulombs/cm2 or lower.  In addition, images can be produced with low contrast, i.e., obtained over a wide exposure range.

Abstract: GAS-LIQUID VORTEX SEPARATOR-ELIMINATOR                 Abstract of the Disclosure A gas-liquid vortex separator-eliminator for removing gas present in the liquid in a forced-liquid circulatory system.  The gas-liquid separator-eliminator has an upright main body which has an upper chamber and a lower chamber.          The upper and lower chambers are separated by a horizontal wall that has a gas discharge port in the center thereof.          An inlet has an integral diffuser positioned immediately inside of the lower chamber.  There is also an outlet which has a horizontal axis which is generally aligned on the horizontal axis of the inlet and which generally perpendi-cularly intersects the vertical axis of the upright main body.  When the separator-eliminator is in operation, the liquid enters the inlet, is directed into the lower chamber and exits via a vertical pipe leg and the outlet.  The water is forced tangentially against the side of the lower chamber and downwardly in the lower chamber, respectively, so as to form a water vortex in the lower chamber whereby the gas dissolved and entrained in the liquid is released in the form of bubbles.  The horizontal separating wall is positioned to prevent the tangential water motion in the lower chamber from forming in the upper chamber when the separator is in operation.  The upper chamber contains an air eliminator.  The gas bubbles rise into the upper chamber and are purged into the atmosphere by means of the air eliminator/vent.

Abstract: ABSTRACT OF THE DISCLOSURE         A device for providing a clamping joint comprises an inner sleeve and an outer sleeve with complementary threads, such threads each having a flank constituting a clamping surface.          Clamping takes place upon relative axial displacement of the elements, creating a wedging action.  Relative rotation of the sleeves may occur.  Sleeves anti-rotation means are provided to prevent such relative rotation from occurring beyond a predetermined point.  The axial displacement can be brought about by screws arranged axially in bores in a flange on one element.          In order to prevent accidental disengagement of the elements, at least one of the threads adjoins at one end to a part which is wedged against an opposing thread flank when the elements are rotated in relation to each other over a predetermined end position.

Abstract: ABSTRACT      A digital mode phase modulation type position detector utilizing  a  resolver  as  the  phase  modulating  element  is disclosed  in  which  the  phase  of  the  modulated  signal  is determined by comparing it with that of the follower signal, the phase of which  is adjusted  to  that of  the  modulated signal.  The phase difference between the modulated and the follower signal is detected at the ends of the half-periods thereof to effect the adjustment.   To make the adjustment more precise, an adjustment circuit may further be provided which generates evenly spaced pulses  in the present half-period of the follower signal at a frequency corresponding to the rotational speed of the resolver during the preceding half-period of the modulated signal.  These pulses are used to adjust the phase of the follower signal more closely to that of the modulated signal. The position counter  is also provided  to accumulate  the   values  corresponding  to   the phase  differences  between the  modulated  and  the  follower signal  and/or  the  number  of  the pulses of  the adjustment circuit. Thus, the accumulated value in the position counter represents the overall rotational angle of the resolver from the beginning of the counting up to the present instant.

Abstract: Means for Pulling Tape from a Reel Abstract of the Disclosure The present arrangement includes a first tape leader which can be readily and automatically coupled to a second tape leader. In a preferred embodiment the first tape leader is connected to be wound on a take up reel while the second tape leader is connected to a tape to be pulled from a supply reel.  The first tape leader has one end formed into a mushroom like tab with a supporting stem.  The second tape leader has a locking aperture at one end thereof which is proportioned so that a wide section thereof can fit over said mushroom like tab while d narrow section thereof will accept the stem but block passage of the mushroom tab therethrough.  Accordingly when the tab is passed through the wide section and the leader is moved (pulled) toward the narrow section of the locking aperture, the tab and part of the stem become locked in the narrow section.  Hence the leaders are locked, or buckled, to enable the first tape leader to pull the second leader.  The first and second tape leaders each have a smoothing aperture therein which provides d means to accept the bumps created by buckling the tab into the locking aperture so that the wrapped around leaders are in a smooth configuration when pulling a tape.
