Abstract: ABSTRACT            A liquid sulphur gas scrubber apparatus for removing hydrogen sulphide and polysulphides from liquid sulphur disposed in an enclosed reservoir.  The apparatus comprises an outer casing extending upwardly from the reservoir in which a liquid sulphur downflow passage means is disposed.  Downwardly canted baffle plates extending into the passage means in alternating fashion in opposing directions provide a cascade type downflow path which agitates the liquid sulphur and causes the release of sulphide gas therefrom.  This gas is vented from the apparatus by means of openings disposed below the baffle plates and gas discharge and venting passages provided in the casing.  Supply means for pumping liquid sulphur from the reservoir to the upper-most baffle plate in the downflow passage means is also provided.

Abstract: APPARATUS FOR RECORDING A VIDEO SIGNAL     ABSTRACT OF THE DISCLOSURE     Video signals are recorded in successive record tracks on a record medium without guard bands or spaces between adjacent tracks, thereby enhancing the utilization of the record medium.  Interference between the signals recorded in adjacent tracks is avoided during reproduction thereof. by recording such video signals in adjacent tracks with their respective synchronizing signals aligned in the direction substantially at right angles to the length of the tracks and with carrier components of the signals recorded in the adjacent tracks being of the same frequency and having-the same phase relation to the effective scanning direction during recording.  During reproduction of the sig-nals thus recorded, non-interfering signals recorded in two or more adjacent tracks are simultaneously reproduced by a reproducing magnetic head without the necessity of a servo tracking arrangement to align the scanning paths of the mag-netic reproducing head relative to the record tracks.          Preferably, an apparatus for recording video signals in accordance with the present invention includes a record medium, a rotatable signal recording transducer by which the video signals are re-corded on the record medium in successive record tracks which extend substantially parallel to each other, an input terminal to which the video signals are supplied, an output terminal from which a modulated video signal is supplied to the signal record-ing transducer, and a signal modulator connected between the input and output terminals to modulate signals applied to the input terminal and to supply the resulting modulated signals to the output terminal.  The apparatus further includes a signal gen-erator for producing alternating signals corresponding to the rotational phase of the transducer relative to the record medium, a variable frequency oscillator connected to the modu-lator to supply a carrier signal thereto, and a phase compara-tor connected to the oscillator and a signal generator for com-paring the phase relation between the outputs of the variable frequency oscillator and the signal generator, the output of the comparator being applied to the variable frequency oscilla-tor so that the output phase thereof is controlled by an error signal of the comparator in response to the rotational phase of the transducer relative to the record medium.

Abstract: ABSTRACT     The disclosure is directed to a liner assembly for an autogenous ore grinding machine.  The machine includes a large cylindrical drum which is rotated about a horizontal axis to comminute the ore.  The liner assembly covers the inner cylin-drical surface of the drum and consists of a plurality of longi-tudinal segments which are removeably bolted to the drum.  Each segment is made from a material which has good impact resistance and defines an irregular grinding surface to assist in the ore grinding process.   An opening is formed through the segment body and extending longitudinally thereof, the opening being defined by walls that converge from the segment mounting surface to its grinding surface.  A plurality of inserts, formed from material which is highly resistant to abrasion, are disposed in the opening and cooperate with the converging walls and each other in wedging relation for retainable engagement with the segment body bolted to the drum.  The segments together define a grinding surface which assists in reducing the wear rate of the segment body, and thus the entire liner assembly.

Abstract: MOTOR GRADER CIRCLE DRIVE                   A B S T R A C T      A motor grader circle drive has an internal spur gear secured to the circle, and the internal gear is driven by one or two barrel worm gears, each of which in turn is driven from a hydraulic motor by an input worm and an input spiral gear keyed to the barrel worm gear, each barrel worm gear is journalled on a spindle in a support and is free to move endwise between a pair of radial flanges while being centered by a pair of belleville spring washers so as to compensate for backlash in each barrel worm gear and to per-mit substantially even distribution of driving force be-tween the barrel worm gears when two are used.  This struc-ture operates at very low tooth pressures so as to permit the barrel worm gear to be made of a relatively soft material such as heat treated aluminum.   The support, worm gear and input gears are made as a prefabricated sub-assembly, which is easily installed or removed; and using a soft material which wears much faster than the internal gear protects the latter from wear.

Abstract: TITLE        CONTENTS-CONSERVING PLUNGER FOR CARTRIDGE   ABSTRACT          A cartridge plunger has a flexible forward wall with a forwardly extending central projection shaped to fit part way into the nozzle.  The flexible forward wail is moved to a rearward position when the plunger engages the contents of the cartridge as it-is inserted in the rear end of the cartridge.  Although the forward-extending projection displaces some of the contents, the volume made available around the projection from the forward wall being in the rearward position is greater than the volume displaced by the projection.  This allows a slight increase in the total volume of contents loadable into the cartridge, and when the plunger is forced against the front of the cartridge, the contents are not only forced out of the cartridge itself, but also from a portion of the nozzle occupied by the forward projection of the plunger.  This dispenses the slightly larger volume of cartridge contents more completely for fully delivering a standard volume of contents without change in standardized size and shape of the cartridge.
