Abstract: Abstract Parts of a composite video signal, such as segments of each horizontal scan line, are stored in analog storage devices and retrieved therefrom in a cyclic manner to rearrange them and thereby encode the signal.  The cyclic retrieval of the information from the storage devices is carried out on a selective basis in accordance with the binary state of a pseudo-random signal that is generated independently at each of the encoding and decoding stations.  Synchronization of the two independently generated signals is provided by a control word and an initialization word that are transmitted with the encoded video signal, one of which is encryptd.  Decryption of the word is carried out with a master key at each of the encoding and decoding stations.

Abstract: ABSTRACT A low-temperature pump having a throttling valve formed by tilting radially disposed vanes in side-by-side relation, capable of fully opening a pump port to a process chamber.  Motion from one vane can be coupled to the next through shims which support the vanes and form a seal when the vanes are flat in a common plane.  One of the vanes may be controlled independently of the others so that coarse and fine modes of operation may be achieved by separately controlling (N-1) vanes and the Nth vane.  The vanes are maintained in thermal contact with a chilled outer wall surface of a first pumping stage of a two-stage pump, the second stage coaxially surrounding a first stage maintained at a very low temperature.  A central hub, at the convergence region for the vanes, supports a shield, protecting the second stage from radiation through a port in the upper regions of the pump.

Abstract: ABSTRACT OF THE DISCLOSURE           Disclosed herein is an apparatus useful for blending solids with fluids.  In a specific application of the blender, sand is mixed with a gel composition to obtain a fluid mixture suitable for stimulation treatments of oil and gas wells.  Basic components of this blender are a slinger member and an impeller member, which are enclosed within a casing.  The slinger and impeller are fastened together, with the impeller being positioned underneath the slinger.  In addition, the slinger has a toroidal configuration and the impeller has a vortex configuration, and the slinger has a larger surface area than the impeller.  The toroidal shape of the slinger, and its larger size, contribute to a good pressure balance within the fluid composition as it circulates inside the casing during the mixing operation.          A more thorough mixing of the sand and gel composition is achieved by improving the pressure balance in the manner described.

Abstract: Abstract A rotary web shearing machine equipped with pairs of rotating helical blades, the improvement for adjusting the clearance between the blades which makes it unnecessary to adjust the blades by their individual holders while the machine is stationary, but makes it possible to effect this adjustment without shutting down the machine. This is accomplished either by providing that one of the blades remains in a fixed axial position, while the companion cutting blade holding shaft is moved axially with respect to the fixed blade.  This is accomplished by the novel mechanism on the end of the shaft of said blade mounted in a special bearing and housing and equipped with an adjusting screw and nut which permits imparting of axial motion to the shaft while it is in rotation  if desired and thus effecting a variation in the clearance between the pair of helical blades eliminating the necessity of shutting the  machine down and resorting to manual adjustment of the blade holders to effect proper clearance.  This adjustment becomes necessary frequently as the blades wear or their cutting action is otherwise impaired.  I may also apply the same  mechanism to each member of the pair of co-acting blades and obtain a greater adjustment in the clearance between blades.  I may also affect this adjustment while the  blades are stationary when occasion demands.

Abstract: ABSTRACT OF THE DISCLOSURE      A fluid-dispenser for a bulk container for potable liquids or the like.  A tubular filling and dispensing gland welded around a hole in a laminated plastic fluid-containing bag contains a sealing cylinder having a diaphragm at an oblique angle that seals its inner end.  A tubular dispensing member with a sharp cutting edge at a corresponding oblique angle is inserted into the sealing cylinder with the cutting edge adjacent but not in contact with the diaphragm.  When the fluid is to be dispensed, rotation of the dispensing member will cut around most of the periphery of the diaphragm to permit the fluid to enter the dispensing member.    Three embodiments of taps for operating the dispensing member are disclosed.  One is a simple tap which,  upon rotation,  cuts the diaphragm and permits the fluid to run into the tap where it may be dispensed through a rotatable valve.  The second embodiment is an unvalved rotatable tube with the cutting edge at one end and a hose or tubing connector at the second end for remote dispensing.  The third embodiment includes means for rotating the diaphragm cutting edge and also a bouble valving arrangement that permits removal of the tap without loss of fluid from either the tap or from a flow of a partially filled fluid bag.

Abstract: ABSTRACT OF THE DISCLOSURE      An  in-line valve pump design  is provided wherein the suction and the discharge valve operate along a central axis coincident and in-line with a reciprocating plunger.   The reciprocating plunger operates within a cylinder and a stuffing box which are independently secured by separate securing means to the drive housing of the pump.  The cylinder thus secured by these independent securing means to the pump housing is also provided with an outer end having a large threaded portion to which a mounting adapter ring is secured.  This ring, in turn, provides the mounted base to which further securing means, independent of the securing means holding the cylinder and stuffing box to the drive housing, are attached.   These second or further securing means are effective to attach the suction and discharge manifold assemblies to the head of the cylinder, and in so doing capture the in-line suction and discharge valve assembly to the cylinder head.  This structural arrangement of the pump elements into,  in  effect,  two  separate  and  independently maintainable subassemblies allows for easy maintenance and disassembly of the fluid end of the pump without disassembling the power end of the pump incorporating the cylinder and stuffing box means attached to the drive housing.  Another aspect of the present invention is that an optimized arrangement of passageways and suction valve return spring location is employed to enhance the volumetric efficiency of the pump.
