Abstract: Abstract Of The Disclosure A method and apparatus for controlling electrode drive speed in a consumable electrode furnace.  The electrode drive speed is regulated at a base speed computed from measured changes in physical characteristics of the electrode or ingot, such as changes in weight, as the melt proceeds.  The base speed also takes into consideration the known geometry of the electrode, the furnace mold or crucible, the density of the ingot material, and the speed of movement of the bottom of the ingot if any.  This base speed is increased or decreased by a trim speed determined from measurement of an electrical phe-nomenon associated with the consumable electrode process, which electrical phenomenon has a relatively long term value related to the distance between the bottom surface of the electrode and the top surface of the ingot.

Abstract: Abstract A revetment panel for installation along embank-ments and other earthen structures, including structures par-tially or fully covered by water, which utilizes a fabric web having a plurality of compartments separated by selvage. The web is formed of two fabric layers, which are woven separately on the same loom to form the compartments, and interwoven to form the selvage.  The fabric layers are separately woven to form slots in the selvage which allow cables to pass through the web, and which allow filler material to flow between compartments during filling.  The web is transported to its installation site, and placed. The compartments in the web are then inflated with the filler material, which may be cementitous slurry or mortar con-sisting in part of sand  and gravel found near the installa-tion site, or simply a mixture of sand, gravel, and water. The resulting matrix of forms interconnected by fabric and cable provides a durable, economical and flexible erosion control layer.  Later, the fabric may wear away leaving a highly articulable mat of hardened forms interconnected by cable or other connecting means.

Abstract: ABSTRACT OF THE DISCLOSURE    An apparatus comprising a rotating substrate holder is provided.  The rotating substrate holder is hollow and adapted to receive liquid gas such as nitrogen to cool the substrate to cryogenic temperatures.  The novel substrate holder is supported inside of a vacuum chamber by a thin wall tube which is sealed with a liquid rotating seal at the point where it passes completely through the top wall of the vacuum chamber.   The novel thin wall tube support provides access to the hollow substrate holder from outside the vacuum chamber and provides temperature isolation of the liquid     in the substrate holder so that the liquid rotating seals are maintained at operable elevated temperatures.

Abstract: ABSTRACT            A unit is provided for synchronizing an incoming PCM frame with a PCM frame to be presented at an output of the unit in accordance with externally generated timing, to ensure correct sequencing of the channels belonging to a wide band information flow.  This flow can consist of a coded video signal coming from a video conference room.          Synchronization is accomplished by appropriate data writing and reading operations effected in a random access memory of a size sufficient to store the information content of two PCM frames, each half of the memory being written suc-cessively with data from the input, and each half succes-sively being read to the output with a temporal offset such as to provide the desired synchronization.

Abstract: ABSTRACT            TRACK CIRCUIT     A railway track circuit arrangement particularly suitable for the short track circuit, down to approximately 40 metres, required in metro transit systems.  Based on conventional A.C. track signalling principles for continuous track rails, the boundaries between adjacent track sections are defined by electric separation zones.  An electrical short is connected between the running rails and an A.C. signal tuning unit is connected approximately 6 metres away to tune the end loop thus formed to resonance at the selected track signal frequency.  The tuning units comprise a capacitor, the value of which is selected for resonance tuning, and a transformer a winding of which is connected in series with the capacitor, and a track circuit signal transmitter or receiver is connected through a second winding of the transformer.  In order to reduce mutual coupling between track circuits by longitudinal leakage, in each joint, two electrical short may be connected between the rails spaced apart approximately 0.75 metre.

Abstract: ABSTRACT UNALIASED QUADRATURE AUDIO SYNTHESIZER     The  apparatus  described unaliases a Doppler signal which is related to the velocity of blood flowing in a sample volume.  It then generates an audio output corresponding  to  the  unaliased Doppler  signal.   The device  generates  an  unaliased,  instantaneous  signal which corresponds to the Doppler frequency associated with the blood velocity in the  sample volume.   That unaliased   instantaneous   frequency   is   fed   into programmable read only memories  (PROMs) which provide digitized values  for the  sine  and cosine  functions.    Those values are fed into digital-to-analog converters, and they are scaled to provide audio outputs.

Abstract: ABSTRACT OF THE DISCLOSURE    A pitched cable is sheathed over a defined length with a plastic polyamide film.  The plastic tube is affixed to the pitched cable so that the outside diameter of the tube is decreased and parts of the inside wall of the plastic tube are entered into the gaps between the turns of the pitch helix.  In that way the tube is firmly fixed onto the cable.  The method of sheathing the pitched cable includes the steps of slipping a plastic polyamide tube over a given length to be sheathed of a pitched cable having a pitch helix and gaps between turns of the pitch helix.  The plastic tube is affixed thereto by hammering to the pitched cable so that the outside diameter of the tube is decreased and parts of the inside wall of the plastic tube are entered into the gaps between the turns of the pitch helix.  The tube is thus firmly fixed onto the cable.

The bottom nut (36) supports the cam ring (34) and is wedged into engagement with the casing hanger (12) by downward axial movement of the running nut (30).  A packoff assembly (16) is threaded on the casing hanger (12) and arranged so that rotation of the plug (40) and stem (22) rotates the wear bushing (14) and the packoff assembly (16) to set the packoff.         The casing hanger (12), wear bushing (14) and packoff assembly (16) are lowered on the running tool (20) into final position within the wellhead.  The running tool (20) is released by rotation of the stem (22) which raises the running nut (30), disengages the wedge (32) and allowing the cam ring (34) to disengage the casing hanger (12).  A dead band between the wedge (32) and running nut (30) prevents accidental release of the running tool (30) form the casing hanger (12), and on further rotation, the running nut (30) becomes a driving element for threading the packoff assembly (16) so as to set the packoff.         Important features of the invention include releasability of the running tool (20) before setting the packoff, if necessary, the aforementioned safety feature, and the capability of releasing the running nut (30) upon the application of low torque after the application of high torque thereto as a driving element.
