Patent CA-1097830-A (CA)
Inventor: RZESZEWSKI THEODORE S
IPC: H03J7/02

Abstract: Abstract of the disclosure A television tuning system is provided which employs a fre-quency synthesizer system for establishing the tuning of the receiver. A first programmable frequency divider controlled by a reversible counter is connected between the output of a reference oscillator and a phase comparator to which the output of the local oscillator, after passing through another programmable frequency divider, also is applied.  The phase comparator output is a tuning voltage used to control the tuning of the local oscillator.  A logic circuit is coupled to sense predeter-mined relationships of signals from a picture carrier detector, a sound carrier detector, and AFT discriminator circuit, and the presence of vertical synchronization signal components for changing the count in the reversible binary counter to adjust the first programmable frequency divider to compensate for channel frequency offsets which may occur in excess of the pull-in range of the AFT discriminator circuit.  To permit operation of the receiver as a signal seek receiver, a pair of signal seek pushbuttons for the "up"  and for the "down" direction, respectively, are provided.  Operation of either of these pushbuttons functions in conjunction with further logic circuitry and in conjunction with timing circuitry to automatically step tune the receiver channel-by-channel in the selected direction until a channel with a signal present is sensed by the first logic circuit, whereupon the signal seek circuit operation is disabled until one or the other of the signal seek pushbuttons is reactivated.  This then provides an improved frequency synthesizer tuning system for a television receiver which includes a signal seek feature which also has a provision for adjusting the synthesizer loop for frequency offsets.

Title: Apparatus for automatically anchoring, twisting, and winding filament, or the like, onto a spool
Inventor: MCLAIN PHILIPPE H
IPC: B65H55/00
Filed: 1977-10-06
Granted: 1979-10-30
Abstract: ABSTRACT OF THE DISCLOSURE The disclosure is directed to a spooling apparatus that can be threaded on the fly to anchor, controllably twist and wind filament onto a receiving spool.  A receiving spool is non-rotatably mounted on a spool shaft for axial reciprocation. A lead-in pulley is spaced axially outboard with respect to the receiving spool and is oriented to rotate about an axis sub-stantially perpendicular to the axis of the receiving spool.  A flier is mounted to rotate concentrically about the receiving spool and presents a pick-up head adapted to engage the feed run of the filament as it passes between the lead-in pulley and an orienting pulley located in proximity to the inboard end of the receiving spool.  The orienting pulley is canted such that the tailing run of the filament cannot be engaged by the pick-up head as it rotates with the flier although the canting of the orienting pulley disposes the feed run such that it will be engaged by the rotating pick-up head when the spool reaches a predetermined position along its range of axial reciprocation. The feed run extends through a cutting mechanism which severs the tailing run therefrom shortly after the pick-up head engages the feed run.  Means are provided in association with the cutting mechanism to grip the severed end of the feed run after severance and until such time as it becomes anchored thereto by successive overwraps.  Means are also provided to assure that the twist imparted to the filament by rotation of the flier with respect to the relative location of the lead-in pulley will not be transmitted across the lead-in pulley and into the run of filament extending between the source of the filament and the lead-in pulley but will, instead, be transmitted across the pick-up head with the filament as it is wound onto the spool.

Abstract: METHODS OF AND APPARATUS FOR PULP-INSULATING A CONDUCTOR               AND PRODUCT PRODUCED THEREBY            Abstract of the Disclosure A coating (28) is applied over an advancing electrical conductor (21) and partially dried by exposing it to a first temperature for a predetermined time.  This renders the coating substantially insoluble in water so that it is retained on the conductor as the conductor is moved through apparatus (34) which forms a ribbon (35) of pulpous material longitudinally with the conductor.  The ribbon is reshaped into an insulative cover (41) concentrically disposed about the coated conductor, after which the pulp-insulated conductor is exposed for a predeteremined length of time to a second temperature which is substantially greater than the first temperature.  This reduces substantially the moisture content of the pulpous material and simultaneously tackifies the coating which cause the pulp insulation to the conductor to form an insulation cover having substantial integrity.

Abstract: 12.2.80                  1                     PHD 79023 ABSTRACT: X-ray examination apparatus comprising a column which is movable in the longitudinal direction of the table and which supports an X-ray source.           The invention relates to an X-ray examination apparatus, comprising a narrow basic frame (100) and a patient examination table (27) which is slidably con-nected to the basic frame (100). This apparatus is particularly suitable for making Bucky exposures. The apparatus offers the advantage that it is very well accessible from the sides, without it being neces-sary to mount guide rails for the stand supporting the X-ray source (26) on the wall or the ceiling. To this end, a column (15 - 16) which supports the X-ray tube (26) is movable along a guide rail (10) which in its turn is movable in the longitudinal direction of the table on a carriage (9), which in its turn is movable in the longitudinal direction of the table on a stationary frame (1). This results in a telescopic movement of the movable parts and in a displacement range which is larger than the value corresponding to the width of the basic frame (100) or the frame (1).
