Abstract: ABSTRACT OF THE DISCLOSURE         An apparatus for detecting the position of a reproduc-ing transducer in an apparatus which reproduces an information signal recorded on a rotary recording medium, the reproducing transducer being transferred in the radial direction across the rotary recording medium, comprises a single photo-detector having a light-emitting element and a light-receiving element, provided in a manner so as to be transferred unitarily with the reproducing transducer, a light interrupting plate located at a fixed part of the rotary recording medium reproducing apparatus, for operating together with the photo-detector, and a position detection signal producing circuit for producing a position detection output signal according to an output of said photo-detector, to indicate that the reproducing transducer has passed a position corresponding to a first predetermined position and a second predetermined position of the recorded region on the rotary recording medium.  The light interrupting plate has a configuration so as to change state be-tween a light interrupting state and a non-interrupting state with respect to the photo-detector, as the reproducing transducer pas-ses a position corresponding to the first predetermined position and the second predetermined position of the recorded region on the rotary recording medium.

Abstract: ABSTRACT OF THE DISCLOSURE           A method for working up residues of an extractive distilling process for obtaining pure hydrocarbons.  The residue from an extractive distilling column is fed to the about middle part of a distilling column.  The hydrocarbons are distilled and removed at the head of the distilling column and the solvent is removed at the bottom of the distilling column.  A sidestream is removed from the distilling column at a position above the feed plate for the residue from the extractive distilling column via a so-called reflux evaporator plate having an elevated level of liquid.  The sidestream is heated by indirect heat exchange with the solvent flowing from the distilling column.  The heated-up sidestream is fed back into the distilling column at a level at or above the reflux evaporator plate.  The concentration of the solvent at the reflux evaporator plate is controlled by the amount of reflux at the head of the distilling column.         The heating of the side stream reduces the heat requirement of the bottom boiler of the distilling column by about 35 percent.

Abstract: ABSTRACT OF THE DISCLOSURE     The present invention relates to an integrated circuit device particularly of the type carrying multiple memory circuits or the like.  The device incorporates a lead frame of the sort which includes an elongate metallic web and is characterized by the lead frame providing an integral seat or platform whereon is mounted a capacitor device which is connected or adapted to be connected in shunting relation of the power supply inputs to the integrated circuit device, whereby the capacitor provides a convenient mounting platform for the circuit bearing elements and also assures minimal lead lengths between the capacitor and the power supply inputs of the circuit bearing chip.          Due to the shortness of such lead lengths and consequent reduction of the inductance reactance of the power supply circuit, efficient dampening of switching transients is achieved with the use of capacitors of much smaller values, in less area than heretofore required in external dampening applications.

Abstract: ABSTRACT OF THE DISCLOSURE         A device for detecting, on a record medium, positions of interband regions disposed between bands of recorded formation on the medium, detects differences in reflectivity of the regions and the bands by emitting electromagnetic radiation to be incident on a recorded surface of the medium containing the bands and regions, and detecting the level of the radiation reflected thereby. radiation source, such as an LED, emits a beam of radiation to be incident on the medium.  A detector, such as a photo transistor, detects the intensity of the beam reflected from the medium and provides an output level that varies  with the intensity of the reflected beam.  An interband region detecting circuit provides an output signal in response to variations in the output level to indicate the presence of the interband regions.  In order to automatically control the current furnished to the radiation source so that the intensity of the reflected beam is maintained within an optimum range of the detector, an average level detecting circuit, which can include an integrator, provides a time average of the detector output to a current control circuit whose output is connected to the radiation source.  Thus the emitted level of radiation from the source is automatically increased if the record medium has a low reflectivity, and is automatically decreased if the record medium has a high reflectivity.     -i-

Abstract: Abstract Uniform Field Solenoid Magnet With Openings A solenoidal magnet coil is used to generate an axial field for focusing a beam of electrons through a linear-beam electron tube.  In high-power tubes, the coil typically cannot extend over the entire length of the focused electron beam because it would interfere with the waveguide used to carry out the generated wave power.  Thus the axial mag-netic field strength falls off near the output end, a region in which it would be desirable to have it uniform or even slightly increasing.  Very often the coil is foil-wound and its output end has a notch to allow passage of the waveguide.  A similar notch 180 degrees away compensates the sideways distortion of field caused by displacement of coil current away from the notch impediment. In the non-notched regions the current spreads throughout the coil cross-section, but there is still a fall-off of field strength on the axis due to current displacement away from the output end.  The invention comprises a second pair of notches in the end of the coil opposite the output end and azimuthally spaced between the first pair. These notches deflect the current toward the output, compensating the magnetic field fall-off.

Organic binders and plasticizers are added.  Then the slurry is spray dried in a centrifugal separator.  The resulting powder is poured into a mold and a tubular green body is formed by isostatic pressure.  The tube may be sintered to size as a whole and then cut into lengths; i.e., pellets, or the green body may be cut into green-body pellets which are then sintered.

Abstract: DISC PLAYERS FOR REPRODUCING AN INFORMATION               SIGNAL FROM A ROTATING DISC                  ABSTRACT OF THE DISCLOSURE         A player for reproducing an information signal from a rotating disc having record tracks having a spiral signal path in which the information signal is recorded.   The player is adapted to perform a small scale track jump operation for rapidly moving the reading position in directions transverse to the spiral signal path by relative-ly short distance repeatedly in the fast forwarding or fast reversing mode.  The movement is so arranged that the number of times of the small scale track jump operation is performed repeatedly for a period in the fast reversing mode is larger than the number of times of the small scale track jump operation performed repeatedly for the same period in the fast forwarding mode.  By this means, the moving distance along the spiral signal path in respect of the reading position by a pick-up device moved for the period in the fast forwarding mode substantially coincides with moving distance measured in the same manner in the fast reversing mode.
