Abstract: HELICAL FIELD STABILIZATION OF PLASMA DEVICES     ABSTRACT OF THE DISCLOSURE     A toroidal plasma device has a toroidal confine-ment vessel defining a toroidal space and confining ionized gas therein.  A solenoid which links the toroidal space induces a toroidal electric field therein to produce plasma current.  A plurality of first windings are wound sub-stantially helically around the vessel substantially equally spaced around its minor circumference.  A plurality of second windings are wound substantially helically around the vessel substantially midway between successive first windings.  Direct current is passed through the respective first and second windings in opposite directions with the current in the respective first and second windings equal or slightly unbalanced.  The currents in the first and second windings produce a helical magnetic field.  The combi-nation of the poloidal magnetic field from the plasma current with this helical magnetic field produces a separatrix in the toroidal space, this separatrix defining a closed sur-face which limits and encloses a region within which closed and nested magnetic flux surfaces exist.

Abstract: PATENT APPLICATION   ON METER ROTOR ROTATION OPTICAL SENSOR                           BY ROBERT J. HOSS                 ABSTRACT OF THE DISCLOSURE     Electrical consumption registered in a watthour meter is converted into an electrical analog suitable for trans-mission to a remote monitoring site by reflecting light off   the  watthour   meter   rotor,   the   light   being periodically interrupted during each rotor rotation by a darkened  light  absorbing  area  of  the  rotor  which traverses the light beam, passing the light to and from the  meter  through  fiber  optic  cables  and  digitally counting  at  a  distant  location  each  of  the  pulses corresponding to the rotor rotation which are transduced from the light re- flections.  By generating the light from  an  AC  signal,  AC  signal  processing  techniques employed  in  the  light  reflection  detection  circuitry ensure   a  useable   electrical   analog   with  minimal likelihood  of  error otherwise  arising  from  spurious noise and varying ambient temperature related signals.

Abstract: Hoe 78/K 083 PROCESS FOR THE PREPARATION OF             PLANOGRAPHIC PRINTING FORMS     Abstract of the Disclosure A process for the preparation of planographic printing forms is described, in which a light-sensitive material composed of a support having a hydrophilic surface and of a light-sensitive layer, which contains a 1, 2-naphthoquinone-diazide, is exposed imagewise, developed and then heated to a temperature above 180° C for such a time and at such a temperature level that an oleophilic precipitate is formed on the hydrophilic image back-ground, and the precipitate is then removed by treatment, for ex-ample wiping over, with an aqueous solution of about 0. 01 to 50% by weight of polyvinyl phosphonic acid. The treatment has the advantage that in this case the support surface, for example anodically produced aluminum oxide, is not significantly attacked and is nevertheless completely freed from impurities.

Abstract: ABSTRACT OF THE DISCLOSURE    An input coupling circuit for detuning the Q of a high-Q ferrite rod antenna is disclosed.  A high-impedence low-noise amplifier is used to amplify the output signal from the LC resonant tank of the rod antenna.  A portion of the amplified signal is fed back directly into the mag-netic circuit of the antenna tank.  This negative feedback reduces the losses produced in the magnetic circuit due to the presence of nearby conductors.  As a result of this reduction, an increase in the antenna sensitivity and a decrease in the cross-feed from other nearby antenna is produced.

Abstract: DIGITAL CONCENTRATOR  SWITCH            Abstract of the Disclosure In  a  fully digital  telephone switching system, a digital switch may serve a number of PCM sub systems each having separate-forward and reverse highways and each serving a number of subscribers' lines.  The highways are grouped in blocks of eight, from which intelligence is received in serial byte-interleaved form and converted by serial-parallel converters to parallel byte-interleaved form.  While in this form they are switched to other channels and applied to a super-multiplexer which they leave in parallel byte-interleaved form from which they are restored by another converter to serial byte-inter-leaved form for application to the switch's outputs.          For  the  reverse  channel  the  arrangement  is  the reverse of the above, i.e. serial-parallel conver-sion, switching and parallel-serial conversion to the  line multiplex highways.   For  local calls a loop-back connection is provided via a fixed delay of half a frame time.  Thus, if the outputs fail, the  arrangement  can  still  handle  local  calls.          Further it is usable on its own as a small exchange.

Abstract: Title:   SELF-ADJUSTING SHOCK ABSORBER HAVING STAGED METERING     ABSTRACT OF THE DISCLOSURE     In a fluid displacement-type shock absorber, a piston res-ponding to an impacting load moves within a cylinder, forcing hydraulic fluid therein out of one or more orifices into a reser-voir.  The resistive force of the piston depends upon its velocity, and the area of the orifice or orifices which control the rate at which the fluid can be displaced.  The total available orifice area for discharging fluid from the cylinder is progressively reduced as the piston is displaced from its initial position upon impact.  The fixed orifice structure defines successive control regions, each of which is designed to provide a predetermined resistance profile and related deceleration control for a respec-tive load system or mass system.  The lightest mass system, traveling at its maximum velocity within the design range, reaches its limiting deceleration rate in the first control region.  The heaviest mass system traveling at its lowest velocity within the design range, reaches its limiting deceleration rate in the last control region.  All loads in the design range are decelerated over the full stroke of the piston in being brought to rest.
