Abstract: ABSTRACT OF THE DISCLOSURE         A chain operator for a window, and particu-larly a skylight window, having a casing with a chain storage area from which a chain can be advanced for opening of the window.  The casing is constructed for mounting of different types of drive mechanism for a chain drive sprocket within the casing.  A unitary liner is fitted within the casing to provide a reduced friction mounting for the drive sprocket and a reduced friction guide for the chain with the liner being positioned in high load and high wear areas to result in smooth and quiet long-life operation.  The chain operator has a chain composed of solid links pivotally interconnected by U-shaped links and interrelated in a manner to readily move between straight and curved configurations and operate under relatively heavy load.

Abstract: TUNGSTEN HALOGEN LAMP WITH HEAT-DISSIPATING BASE                            ABSTRACT    A high temperature tungsten halogen lamp having improved lamp strength so as to reduce lamp breakage.  The ceramic base for supporting the press sealed end of the lamp's envelope has a top thereof including a pair of upwardly projecting members that extend above the press sealed portion to contact the bulb portion of the lamp envelope (or capsule).  These corner projecting members enable enhanced support while at the same time providing a pair of windows therebetween to enable sufficient heat dissipation (thus preventing excessively high lamp seal temperatures).  In accordance with the method of the invention the envelope is cemented to the ceramic base in a two-step operation including firstly cementing the base below the projecting members to bind the base to the envelope's press sealed portion and thereafter cementing the projecting members to the envelope's bulb portion.

Abstract: BIT COMPRESSION MULTIPLEXING          Abstract A bit compression multiplexer for a pair of time division multiplexed digital bit streams each one of which includes a plurality of PCM encoded signals deposited in separate and distinct channels and signaling bits multiplexed therewith.  The encoded signals are bit compressed, and then multiplexed and grouped into clusters.          Each of the multiplexed compressed signals occupies a separate and distinct channel of a repetitive frame that includes a plurality of clusters and a corresponding number of additional channels, called delta channels, each one of which is associated with a given cluster and is proximate thereto.  The signaling bits are extracted from the pair of digital bit streams, reformatted and then placed in predetermined bit positions of the delta channels.  The signaling bits in a given delta channel are associated with the compressed signals of a cluster proximate thereto.  The combination of a cluster and its related delta channel comprise a bundle.  A framing bit pattern is developed for each bundle and the framing bits are placed into a predetermined bit position of each of the delta channels.          The framing bit pattern is arranged to detect frame slips which occur either at a transmitting bit compression multiplexer, at a receiving bit compression multiplexer or at other components of the transmission system, for example, at a Digital Access and Cross-connect System (DACS).

Abstract: ABSTRACT     A well cementing valve is shown which includes a tubular mandrel  having  at  least  one  lateral  port  and which is adapted to be made in a well tubing string.   An external seal ring having a seal region circumscribes the mandrel on one side of the lateral port.   An axially movable sleeve valve  initially covers  the mandrel ports on the mandrel exterior.  The sleeve valve has a pressure responsive seal area subject to fluid pressure in the mandrel for moving the sleeve  valve.    An  axially  slidable  protective  sleeve initially surrounds the mandrel and the sleeve valve.

Abstract: Abstract Apparatus for controlling the field or frame store signal processing of standard and nonstandard video signals is disclosed. The apparatus includes a nonstandard signal detector which compares the received horizontal sync signals to a horizontal sync signal generated internally be counting down a clock signal having a frequency proportional to the color subcarrier frequency. The detector produces a control signal which is in one state when the horizontal sync signals are substantially in coincidence and in a second state otherwise. This control signal is applied to apparatus which switches from field or frame store signal processing apparatus to alternative signal processing apparatus, which does not include a field or frame memory, to minimize distortion of the image when nonstandard signals are processed.
