Abstract: ABSTRACT OF THE DISCLOSURE A combination lock of the dial and sleeve type has a scramble feature enabling a hasp to be engaged with a latch of the lock even when the dials and sleeves are not on-combination, by independent movement of the latch relative to manual actuating means of the lock. When the hasp is engaged, it supports the latch in a position in which the latch is adapted to engage a blocking element that prevents the latch from being moved out of its hasp-engaging position independently of the manual actuator.  This arrangement effectively prevents the lock from being forced open when the hasp is engaged.

Abstract: SUPERVISORY CONTROL SYSTEM              ABSTRACT      An automatic supervisory control system is arranged to provide monitoring and supervisory functions in a noisy electrical environment over communication channels which are also noisy and generally highly congested. The system is designed to handle a large number of status monitoring stations which provide status signals, a relatively small number of display elements, memory elements for storing the status signals and control means for enabling the status stations, the memory elements and the display elements so that the large numbers of status signals can be stored, read out, and displayed in a relatively small number of display elements on a closed loop basis without destroying status signals until responsive action has been taken on the status signals.    The system includes a central control station linked to a plurality of status stations by a single dedicated or shared radio channel, a plurality of telephone wire lines, or a combination of both.  A coded signal is used to com-municate status signals and command signals between the central control station and the status stations.  The central control station includes the status display elements, the memory elements, an audible alarm indicator, printed status and command reports, a keyboard for data entry and a computer for controlling system operation.

Abstract: Abstract:         A caulker dispenses two viscous components contained separately in inner and outer molded resin chambers.  The outer chamber holds one of the components around the inner chamber and is generally cylindrical with standard dimensions to fit existing caulking guns and dispensing equipment.  The second component is held within collapsible inner chamber arranged inside outer chamber and having accordion pleats that collapse when axially compressed.  Inner chamber has a rear end filling opening, and a molded resin plunger fitting closely within outer chamber is secured to the rear end of inner chamber.  The forward regions of both chambers join and form passageways merging at the forward end of caulker.  Inner chamber is sealed by an openable barrier, and a removable closure element seals outer chamber.  When barrier is opened and closure element is removed and a nozzle with a static mixer is attached, plunger can advance within outer chamber and collapse inner chamber forcing both components and from their chambers and through static mixer before being dispensed out nozzle.

Abstract: ABSTRACT OF THE DISCLOSURE In high-voltage switchgear, apparatus for preventing two switches from being closed at the same time to prevent their being electrically paralleled relative to a common bus. The position of each switch is mimicked by a rotatable cam having a notch. When either switch closes while the other switch is fully open, its cam moves a member into the path of the notch in the other cam which is blocked from rotating, preventing the other switch from closing. If both switches attempt to close simultaneously, the member either blocks both cams or blocks one while permitting the other to rotate. If one switch attempts to close while the other switch opens, its cam continues to be blocked until the one switch is returned to full open.

Abstract: LOG-FEED APPARATUS                 Abstract of the Disclosure A log-feed apparatus used in a log-feed assembly, where the assembly functions to advance a log along a transport axis in a log-debarking system.  An elongated arm in the apparatus is mounted at an inner end for swinging of its outer end toward and away from the transport axis.  A spiked feed roll, journaled on the outer arm end for powered rotation about the arm's long axis, is carried on the outer end of a shaft which is journaled on the arm by a pair of axially spaced bearings.  A gear reducer mounted on the arm, intermediate the arm ends, is driven by an arm-mounted motor through a flexible belt drive.  The output of the gear reducer is drivingly con-nected to the inner end of the shaft by a torsionally flexible rotary coupling.  The shaft and bearings journaling the feed roll on the arm act to isolate all components of the drive train which extend between the shaft and motor from substantially all but torsional load transmitted by the feed roll during operation of the log-feed assembly.
