Abstract: ABSTRACT OF THE DISCLOSURE         A manually actuated coupler hydraulically con-nects large diameter high pressure conduits while the conduits are pressurized.  One of the conduits is provided with a body 11, a sleeve 12, and a lever 13 for effecting relative movement between the body and the sleeve.  The other conduit is provided with a nipple 14.  When the nipple and body are initially connected, they cooperatively define a chamber 43 which is hydraulically isolated from both conduits.  The lever is then rotated to advance the sleeve toward the nipple and to open poppet valves 33, 34 in the sleeve and nipple to hydraulically connect the con-duits through the chamber 43.  The sleeve includes a pressure balancing area 48 which is in open fluid pressure communication with the chamber 43 under con-ditions, so that high fluid pressure from either conduit will pressure balance the sleeve.

Abstract: ABSTRACT OF THE DISCLOSURE       A thrust bearing/coupling component for use in scroll-type apparatus which may be a compressor, expander, fluid pump or vacuum pump.  The resulting apparatus is particularly suited for use as auxiliary equipment in automotive power systems.  The component of this invention comprises rotating or oscillating load carrying members, preferably ball bearings, confined with-in facing indentations cut in the orbiting scroll member end plate surface and an associated surface in a member stationary with respect to the orbiting scroll member.  The thrust bearing/ coupling component couples the stationary and orbiting scroll members in a predetermined angular relationship and it may be used to carry either expansive or compressive axial loads on the scroll members to achieve efficient radial sealing of the moving scroll fluid pockets while controlling surface wear-ing so that the scroll apparatus may be operated for an ex-tended period of time without servicing.

Abstract: ABSTRACT OF THE DISCLOSURE      This invention relates to centrifugal separators of the kind having sludge ports at the rotor periphery to be opened dur-ing operation and separate outlets for separated heavier liquid phase and separated lighter liquid phase.  To reduce the losses of valuable lighter liquid phase during total discharge or partial discharge of the separator by opening the sludge ports, the centrifuge is provided with an overflow device connected to the heavy phase outlet, said overflow device having an inner annular overflow and also having a number of passages at a larger di-ameter than the inner overflow border.  the passages are dimen-sioned to let through all heavier liquid phase in normal opera-tion but not to let through an increased amount of heavier liquid phase fed to the separator just before opening the sludge ports for the purpose of displacing the interface between the heavier and the lighter liquid phase towards the rotor axis to a level that corresponds to said inner overflow border.  In order to push the interface between the liquid phases inwards before discharge, no other action is therefore needed than an additional supply of the heavier liquid phase.

Abstract: ABSTRACT A wire cutting, skinning and wrapping tool is able to perform two successive skinning and wrapping operations in order to interconnect two ter-minals with an insulated wire, the wire being skinned over a predetermined length by means of a bit which is provided with a longitudinal groove and which is able to slide in a forward and backward direction in a hollow sleeve, the bit moving from a backward position to a forward position during the skin-ning operation, the skinned wire portion being situated in the longitudinal groove during the two skinning operations.  The sleeve is provided with a nor-mally closed longitudinal slit, the insulated wire opening the sleeve longi-tudinally and passing through the slit during the skinning operations and that the sleeve closes again when the bit is in its forward position after each skinning operation, the predetermined skinned wire length being captured in the groove between the bit and closed sleeve.  In this way, the sleeve can be kept stationary since during each wrapping operation it is closed, the insula-ted wire being located outside the sleeve during the wrapping operations.

Abstract: A COMPATIBLE AM STEREO BROADCAST SYSTEM                      ABSTRACT      A compatible AM stereo broadcast system has a pair of carriers in quadrature are separately modulated with stereo information. The resulting signal is multiplied by the cosine of an angle 0, the angle between the vector sum of the two carriers and a line that bisects the angle between the carriers in quadrature.  The signal envelope contains the sum of the information on the two channels, thus providing compatible monophonic reception.  In a stereo receiver the two carriers in quadrature can be restored by dividing the signal by the cosine of the angle ?.  The original modulation can be obtained from each channel by product detection.

Abstract: ABSTRACT OF THE DISCLOSURE    A solid state digital television camera has a solid state image sensing device, an A-D converter for converting the output of the image sensing device to a digital color signal, a filter for providing a predetermined filter characteristic to the digital color signal, and a digital color modulator for modulating the output of the above filter to produce a digital modulated signal.      In this digital television camera, the process rate between the solid state image sensing device and the filter is selected to a sampling rate of the solid state image sensing device or   where fsc is a color subcarrier frequency, p is 3 or 4, and m and n are relatively small integers. The process rate for the remains is selected to pfsc.  In addition, a D-D converter for converting the process rate from   to pfsc is provided between the filter and the digital modulator. Thus, the digital television camera is operated at a relatively slow sampling drive rate and hence suitable for integrated circuit construction.
