IPC: H01R43/02
Filed: 1988-10-13
Granted: 1992-05-12
Abstract: Docket No. M-503 Abstract of the Disclosure This invention relates to a deactivatable tag useable with an electronic article surveillance system and comprised of planar conductive material cut into a pair of inverse, first and second spiral conductors wrapped about each other and positioned for capacitive and inductive coupling.  The invention also relates to method of making tags wherein conductors are cut from a planar web of conductive material in a continuous process in a manner that the cutting results in the formation of two spiral conductors without accompanying waste of conductive material, and thereafter positioning the conductors to provide resonant circuits.  The conductors of each pair are connected by welding to provide a reliable circuit.  A film of electrostatic-charge-draining material on a web of deactivatable tags prevents their premature deactivation.

Title: Tuner for receiving television signals in two different systems
Inventor: SATOH KEN
IPC: H04B1/16
Filed: 1988-11-16
Granted: 1993-01-26
Abstract: ABSTRACT OF THE DISCLOSURE           A  tuner  for  use  in  two  systems  utilizes  a determining circuit.  To determine whether or not a baseband signal, after demodulation includes a sound carrier.  If a sound carrier is present, the determining circuit determines that the received television signal is a television signal in the NTSC system, or if a sound carrier is not present, a television signal in the MUSE system.    When the received television signal is a television signal in the NTSC system, switches are activated such that the baseband signal is applied to a signal processing circuit for video and a signal processing circuit for sound which are compatible with the NTSC system.  An averaging AFC is selected by these switches.  On the other hand, when the received television is a television signal in the MUSE system,  switches are activated such that the baseband signal is applied to an MUSE decoder, and a keyed AFC is selected.

Title: Method and device for the distance control of a positioning drive, in particular for elevator installations
Inventor: KINDLER GERHARD
IPC: B66B1/30
Filed: 1988-11-17
Granted: 1992-09-01
Abstract: ?bstract With this method it is possible to improve the command performance of distance controlled positioning drives, as well as their posi-tioning performance in the region of destination, also if different interferences, such as for instance changing load- and friction con-ditions act, from travel to travel, on the positioning drive.  For this the distance control is periodically optimized to a constant set of standardized operating parameters and the position errors caused by interferences eliminated at every travel.  For the peri-odic optimization of the distance control the same is designed as cascade control (KR) and fourfold forward corrected by direct bias of the leading (?) nominal values of the jolt (or jerk) (RS), of the acceleration (BS) as well as of the velocity (VS).  For the elimination of position errors caused by interferences a distinction is made between predictable deterministic interferences and not pre-dictable stochastic interferences.  Deterministic interferences are detected quantitatively by a start-up test during the first phase of jolt (or jerk) in the measuring means (29) and a compensation signal (K) is formed from this in the function generator (30), which completely compensates the corresponding position error till the end of the travel.  Stochastic position errors are equalized in the integrating amplifier (13.3) till the end of the travel.  For a range of destination, the remaining residual-distance-control error ( .DELTA. SFR) is increased for a short term in the distance-control error multiplier (35).

The selection circuit (SW) comprises as many gate circuit as there are time multiplexes.  The gate circuits selectively become conductive at determined instants in each time raster in order to select the samples which come from the other participants forming part of the same conference as the corresponding participant and which are to be applied to the addition circuit (CAD) the output signal of which is transmitted to the corresponding participant.  Each selection circuit (SW) is coupled to a memory control circuit (MC) the output of which controls the instants of the gate circuits conductivity.  The contents of the memory of the control circuit (MC) is modifiable according to the identities of the other participants of the conference.

The weight of the superstructure and the tension forces on the drive belt that encircles the track roller frame assembly are advantageously transferred through the collar and the main body along a central vertical plane therealong and to a plurality of roller wheels centrally supported under the base.  Several embodiments of the plate structure and the base are illustrated which collectively define a tubular beam having a particularly efficacious height "h" to width "b" relationship and a back-up shoulder for strengthened connection with the tubular casing. Moreover, the base and plate structure utilize formed plates having a rectangular cross section or a U-shaped cross section in order to minimize welding.

Abstract: VACUUM SUCTION TYPE ANTI-CLOGGING AND DIALYSIS           DEVICE FOR FILTRATION SYSTEMS               ABSTRACT OF THE DISCLOSURE      A method and apparatus wherein a conventional vacuum operated filter unit which generates a positive pressure on the particulates in a suspension against a filter membrane is converted into an anti-clogging filter unit through addition of a supplemental device which generates a counteracting negative pressure on the suspension as it is being filtered, thereby pulling the particulates in the suspension away from the filter membrane.  A conventional vacuum-operated filter unit which causes the suspension to be pulled toward the filter membrane by a vacuum source and thereby creates clogging of the filter membrane with particulates from the suspension is converted into an anti-clogging filter unit by the addition of a supplemental device placed into the top chamber of the filter unit wherein the supplemental device generates a negative pressure on the filter membrane through a second vacuum source acting on the supplemental device which causes the particulates to be pulled away from the filter membrane as the suspension is filtered and permits the retentate to rest within the top chamber of filter unit while the filtrate rests within the bottom chamber of the conventional vacuum-operated filter unit.
