Abstract: Abstract of the Disclosure:           A telescoping vehicle radio antenna connector to permit the removal of the upper telescoping sections from the lower stationary section.  A bearing member and stop ring are removably connected, by a retainer, to the stationary section at the upper end thereof to limit the upward movement of the lowermost telescoping section relative to the stationary section.  The retainer has a resilient collar and depending arms having tabs formed thereon which tabs engage slots in the stationary section to maintain the telescoping and stationary sections of the antenna as a unit.  The retainer can be rotated in one direction so that the tabs will be cammed out of the slots to permit removal of the telescoping section from the stationary section.

Abstract: "METERING CUP FOR SEED, FERTILIZER AND THE LIKE" ABSTRACT OF THE DISCLOSURE         The metering cup includes a disc assembly at the base of a hopper having a screen-type impeller driven by a ground engaging wheel with the impeller formed from expanded metal or the like.  An adjustable inlet communicates with the hopper and the air conveyor conduit of an air seeder, communi-cates with the impeller approximately 180° from the inlet.          The adjustable inlet controls the amount of material passing from the hopper through the inlet and the speed of the ground engaging wheel controls the speed of rotation of the impeller and hence the flow of material to the air seeder conduit.          The movement of the impeller through 180° from the inlet to the air seeder conduit, prevents a flow of material, particu-larly fine material directly to the air seeder regardless of the forward speed of the air seeder.

Abstract: ABSTRACT OF THE DISCLOSURE:         The compound 5-amino-4-chloro-2-phenyl-3(2H)-pyridazinone free from 5-chloro-4-amino-2-phenyl-3(2H)-pyridazinone is used as selective weed-killer in a remarkably more efficacious and remarkably less phytotoxical way than the presently known " pyrazon" (mixture of 5-amino-4-chloro-2-phenyl-3(2H)-pyridazinone and 5-chloro-4-amino-2-phenyl-3(2H)-pyridazinone).  The 5-amino-4-chloro-2-phenyl-3(2H)-pyridazinone is obtained from pyrazon by treating said pyrazon with a mineral acid of pre-fixed concentration, obtaining a suspension and filtering such a suspension.  The use thereof as weed-killer is carried out in suitable formulations.

Abstract: ELECTROMAGNETIC PICKUP FOR STRINGED MUSICAL INSTRUMENTS        - - - - - - - - - - - -ABSTRACT           The present invention relates to pickups for electrical musical instruments of the stringed type, having individual elements of unmagnetized material cooperating with the individual strings and separate magnets providing magnetizing force for the elements.          Previous pickups of this type have employed magnet arrangements which provide relatively weak magnetic fields, resulting in an electrical output which is deficient to harmonics.  No solution to the problem of harmonic deficiency due to weak magnetization has been known heretofore.  The present invention overcomes this problem by use of a new magnet design and arrangement.  A pickup is provided including a plurality of metallic, unmagnetized pole pieces having coil means wound around each piece and operatively associated with the strings of the instrument, the pole pieces being aligned in parallel, spaced-apart relationship, generally perpendicular to the plane of the strings, first ends of all of the pole pieces being closely adjacent to the strings, second ends of all of the pole pieces being flat and planar.  The pickup further includes a rectangular bar magnet having a first surface defining a north pole and an opposite second surface defining a south pole, the bar magnet of the pickup being positioned with one surface which defined a pole thereof in surface contact with the second ends of all of the pole pieces.  In a humbucking embodiment, the pickup includes a second set of magnets, pole pieces and coils.

Abstract: ABSTRACT OF THE DISCLOSURE A warning circuit generates warning signals in response to conditions of a vehicle brake system which includes main and back-up brake fluid pumps.  The main pump is engine-driven and ignition-switch controlled.  The back-up pump is relay actuated and battery powered.  A sensor switch opens upon operation of the main pump and a brake switch closes during an operator brake application. The warning circuit includes a first OR gate with inputs coupled to the ignition and brake switches.  The output of the first OR gate is coupled to the relay and to a first warning lamp.  The output of the first OR gate is capacitively coupled to the set input of a set-reset flip-flop and is coupled to the reset input of the flip-flop.  The reset input is also coupled to a terminal of the back-up source.  The Q output of the flip-flop is coupled to an input of a second OR gate through an inverter.  The other input of the second OR gate is coupled to the terminal of the back-up source, to the reset input and to the output of the first OR gate.  The output of the second OR gate is coupled to a controlled switch which becomes conducting to turn on the first warning lamp.  A second warning lamp is coupled to the ignition switch and is coupled to a ground potential through an interruptible connection provided by the sensor switch.

Abstract: FUEL IGNITION AND STACK DAMPER CONTROL CIRCUIT Abstract A control circuit for a fuel supply and ignition control system controls the operation of pilot and main valves of the system and of a motor which controls the positioning of a vent stack damper plate to normally close the vent stack and to open the vent stack at the start of each ignition cycle. At the start of each ignition cycle, a start relay is operated to energize the pilot valve and a spark generator for a trial for ignition interval defined by the excursion time of the damper plate as it is driven to the open position. When the pilot fuel is ignited, a flame sensing circuit oper-ates a flame relay which completes a holding path for the pilot valve and when the damper plate reaches the fully open position, limit switches connect the main valve to the holding path and deenergize the drive motor and the start relay. If a pilot flame is not sensed before the end of the trial for ignition period, one of the limit switches deenergizes the pilot valve, and the start relay prevents reenergization of the drive motor, locking out the system. The control circuit includes a relay check-ing arrangement whereby start-up is prevented if for any reason the flame relay is operated at the start of an ignition cycle.

Abstract: ABSTRACT         A method for eliminating detrimental deposits of con-densable gases in the heat-exchangers of a continuously operating low-temperature installation, without totally shutting down the installation, involves introducing hot gas briefly into the cold end of the heat-exchanger.  The hot gas is at a temperature of between 0°C and +110°C and contains no condensable constituents.          The hot gas may flow almost without pressure through the heat exchanger, or may be introduced into the heat-exchanger until a predetermined pressure is reached and the pressurized gas is suddenly released.  In one arrangement, hot gas is mixed with the cold gas during the cold period in a change - over heat-exchanger.
