Abstract: ABSTRACT OF THE DISCLOSURE         The disclosure describes a loom for high warp tapestry which is made of two rectangular frames in which the smaller one is mounted to pivot inside the larger frame.  The loom is con-structed to mount a warp by having the upper end thereof alternating between the upper part of the larger frame and the upper part of the smaller frame while the lower end of the warp is engaged in the lower part of the second frame.  The mounting of the upper end of the warp on the two frames in alternate manner enables to separate alternate warp threads.  By allowing the smaller frame to pivot inside the larger frame, there is produced a reverse separation of the alternate warp threads with the result that it is possible to insert a weft between two rows of warped threads after which the smaller frame is pivoted to produce an opposite separation of the warp threads.          In this manner, it is possible to fabricate the tapestry without having to criss-cross the weft between the warp threads.

Abstract: ABSTRACT:      In known devices for reconstructing the absorption distribution in a three-dimensional body, the body is not only imaged in a plane which is perpendicular with respect to the axis of rotation of the radiator/detector system, but also in a direction perpendicular thereto.  The radiation is measured in both directions by a two-dimensional detector device.  The reconstruction, however, is problematic and also involves measuring errors if the angle of aperture of the radiation beam in the latter direction (parallel with respect to the axis of rotation) is to large.  These difficulties are eliminated in accordance with the invention in that the body to be examined is imaged from two groups of radiation source positions.  Each group of radiation source positions is situated on an arc of a circle around the axis of rotation, and the part of the two arcs of a circle deter-mines the dimensions of the region in which the absorption distribution is reconstructed.  The detector device (or the detector devices) is (are) arranged between the two arcs of a circle.

Abstract: Case 77049 WATER-ABSORBENT STARCHES                               ABSTRACT Water-absorbent starch products may be prepared by simultaneously drying and polymerizing an aqueous media containing starch, ethylenic unsatu-rated monomer and free-radical initiator. Without necessitating further refin-ing or chemical modification, effective water-absorbent, drum-dried products essentially free from water-soluble salts and free-radical initiator contami-nants and containing a high level of functional water-attractant groups may be directly manufactured.  If desired, the water-absorbent starch products may be further refined to increase the water-absorbent properties of the starch polymer.

Abstract: MULTI-INSTRUCTION STREAM BRANCH PROCESSING MECHANISM                            ABSTRACT             In a high-performance computer which prefetches and predecodes instructions for sequential presentation to an execution unit, at least three separately gated and sequenced instruction buffers for prefetched instructions permit continued sequential predecoding and buffering of instructions from three independent instruction streams identified by multiple branch instructions, some of which may be conditionally executed.  A number of pointers identify a particular one of the multiple instruction buffers.  A first pointer identifies one of the instruction buffers which is to receive the target instruction identified by a branch instruction decoded from another instruction stream contained in another instruction buffer.   Various branch instructions are predicted to be successful or unsuccessful, and in response to this prediction, a second pointer is set to control gating of the proper instruction to an instruction decoding mechanism, either from the original instruction stream of the branch instruction or from the instruction buffer which contains the target instruction.  A third pointer identifies the one of the multiple instruction buffers which contained the instruction last transferred to the instruction execution unit.  A fourth pointer, contained in a queue of predecoded instructions, and which is associated with each branch instruction to be presented to the instruction execution unit, identifies the one of the instruction buffers which was enabled to receive the target instruction.  Result signals from the instruction execution unit, in response to execution of conditional branch instructions, will reset various pointers and busy triggers associated with each instruction buffer, set one pointer to the same condition as another pointer, or leave certain pointers in a present state, such that the next sequential instruction to be transferred to the instruction execution unit is from the proper instruction stream based on the result of the branch on condition instruction.

Abstract: ABSTRACT              An irrigation system in which a continuously travelling sprinkler line is supplied with water from a stationary water supply conduit extending in the direction of the movement of the sprinkler line.  The apparatus is designed to continuously supply water to the sprinkler from spaced risers forming part of the water supply conduit.  A conveyance moves along the water supply conduit.   The  conveyance carries a rotating water manifold with a plurality of water carrying arms extending radially from the manifold in angularly spaced relation to each other for successive connection to water outlet valves on the risers as the conveyance moves along the water supply conduit.  The water outlet from the water manifold is connected to the water inlet of the sprinkler line through a water con-duit having a swivel joint. The water inlet end of each arm has a coupling device for coupling with a valve of a riser and opening and closing the same.  Coordinating means act to close the riser water outlet valve and uncouple the arm coupling device from one riser when another arm coupling device has coupled with another riser and opened the water outlet valve of that riser.  With one coupling device connected to one riser, power assist means and/or movement of the conveyance along the water supply conduit can be utilized to cause the water manifold and water carrying arms to rotate around the connected riser and also relative to the conveyance to bring another coupling device into contiguity with the next riser in the direction of conveyance travel.

Abstract: 14.              REGENERATOR HAVING AUTOMATIC GAIN     CONTROL REFERENCED TO A DATA-PATTERN-DEPENDENT PULSE STREAM            Abstract of the Disclosure A roving reference automatic gain control (AGC) arrangement is used in a regenerator of a pulse code modulation (PCM) transmission system.  An adjustable gain circuit receives a sequence of data pulses and produces a data-pattern-dependent input signal.  A signal channel circuit, responsive to the input signal, produces a data-pattern-dependent detected signal.  Regeneration circuitry, responsive to the input signal, produces a regenerated data-pattern-dependent output signal.  A reference channel circuit, responsive to the output signal, produces a data-pattern-dependent reference signal.  A circuit algebraically combines the detected signal with the reference signal to form a continuously-variable data-pattern-independent gain control signal which is applied to the adjustable gain circuit for controlling the gain thereof.

Abstract: ABSTRACT OF THE DISCLOSURE          Controllable phase shifters containing reactances and valve switching devices are used for compensation and stabilizing purposes in alternating current-energy transmission systems.  There is desired a phase shift which can be contin-uously controlled within variable limits and with comparatively low expenditure in circuit components.  There is provided at least one shunt circuit branch between primary terminals having mutual phase shifted voltages, and a tap provided as a secondary terminal supplies a secondary voltage or potential having a phase between that of the primary terminals.  At both sides of the sec-ondary terminal there are arranged in the shunt circuit branch preferably complementary reactive impedances.  At least one valve switching device, controllable with respect to its gating be-havior, is arranged in series or parallel to one such impedance and renders possible changing the magnitude of the impedance which is effective for the fundemental oscillation, and thus, a change of the control phase angle.  Preferably valve switching devices are provided at both sides, and, of desired, in combination parallel and in series with the impedances to both sides of the secondary terminal, thereby realizing the advantage of a phase angle control in both directions and over wide ranges of the primary phase angle.

Abstract: ABSTRACT OF THE DISCLOSURE         In a vibration absorber for use with aerially suspended conductors and cables, there is described an improved vibration absorber wherein wind or turbulence induced vibrations resulting in travelling waves on conduc-tors cables are absorbed so as to prevent damage to or failure of conductors and related hardware due to fatigue.          Known devices, particularly dampers and spacer dampers, attempt to control merely the amplitude of the waves pro-duced on the conductor and are therefore ineffective in preventing the formation of such waves and the damage that may result.  In this invention, a vibration absorber compris-ing a piston and cylinder device whereby a travelling wave displaces the piston or the cylinder relative to one another causing a fluid contained within the cylinder to be displaced through an orifice in the piston.  The absorbing system thus defined has a mechanical dissipative impedance of value R to inhibit the reflection of a wave propagated on the conductor whereby the wave is absorbed.  The value of R is in the range of   to   where T is the tension of the conductor and M is the mass of the conductor per unit length.

Abstract: SUSPENDED SOLIDS EXTRACTION    SYSTEM AND METHOD     Abstract Of The Disclosure A liquid containing suspended solids is first passed through an electrostatic treater, having no current flow across its electrodes, to initiate nucleation and coagulation of the particles.  Thereafter, it passes through an electrolytic treater wherein current may flow between the electrodes to further encourage coagulation to such an extent that flocculation begins.  The residual effects of the electrostatic treater prevent plating out on the electrodes of the electrolytic treater such that elec-trolysis can occur without sacrificing an electrode, and the electrodes are so arranged that the liquid passes sequentially through groups of concentrated lines of force whose repetitious, powerful action further encourages floc-culation.  From the electrolytic treater, the liquid with its flocculated material is delivered into a clarifying basin so designed that the floc will settle out and be removed from the basin with a minimum of manipulation because of the tendency of such material to immediately dissipate and disperse when handled while still in the liquid.
