Abstract: ABSTRACT OF THE DISCLOSURE      A ballast for regulating current through at least one gaseous discharge lamp responsive to thermal conditions around the ballast. A capacity circuit including a power capacitance is utilized to provide at least a part of the current regulation. The capacity circuit is responsive to a change in temperature and is capable of switching either abruptly or gradually from one capacitance level to another capacitance level. The impedance of the capacity circuit is therefore increased as the temperature increases thereby limiting current through the at least one gaseous discharge lamp during a high temperature situation. Furthermore, this decrease in current has little, if any, overall effect on the light output of the lamp.

Abstract: ABSTRACT OF THE DISCLOSURE An improved method of preparing a fiberizable borosi-licate glass composition is presented.  The constituents of the glass composition are classified into two or more melting groups according to mutual melting properties or characteristics such as volatility, corrosiveness or fusion point.  Of the constituent groups one is selected and prepared as a molten host glass com-position into which the remaining groups are sequentially intro-duced and homogenized, forming a molten glass composition of desired forming characteristics.  The ingredients for the host glass are pellitized and pre-heated in pellet form to a tempera-ture which is just below the fusion temperature of the host glass composition and that which the pellets will not agglomerate.  The heated pellets are melted in a generally horizontally-disposed, continuous-flow main melter.  The molten host glass from the main melter is flowed to a location where glass fibers are formed.  A B2O3- containing additive glass is separately melted and combined (below the surface of the molten host glass and with mechanical mixing) with a larger portion of the molten host glass prior to the fiber-forming location, to give a fiberizable borosilicate glass.  Borosilicate glass fiber is formed at the fiber-forming location.  At least a major proportion of the B2O3 content of the fiber is supplied by the additive glass, so that the main melter exhibits longer life and the volatilization losses of B2O3 are substantially less than that which results when melting the ingredients of the additive and host glass together in the melter.

Abstract: BAFFLE ARM OPERATING MECHANISM    ABSTRACT OF THE DISCLOSURE           In apparatus for molding glass into hollow-shaped articles such as glass containers, glass is delivered to a parison mold wherein the glass is shaped either by a plunger or by a counter-blow with the end of the parison mold, through which the glass is delivered, closed by what is termed a "baffle".  The mechanism for moving the baffle on a con-ventional IS machine must be capable of moving the baffle from an upper, radially displaced position, to a lower aligned position over the mold.  The operation of the baffle seating motion is accomplished by the use of a vertically reciprocable, fluid-operated motor in which a baffle arm carrying piston rod of the motor is turned about its axis during its upward and downward movement.  The control of the fluid supply to the motor and the exhaust from the motor is such that the rate of movement is monitored and controlled.  The piston rod effectively extends through the piston with the lower end of the rod being provided with a cam follower and with the lower cylinder head, in effect, being the cam which in cooperation with the cam follower effects the turning of the piston rod in response to the vertical movement of the piston and rod.           The cam follower is of a design such that it is less subject to damage through continuous use and the lower cylinder head is such that no seal is necessary between the piston and the lower rod section that carries the follower.

Abstract: Abstract A bubble memory device has a minor loop bubble track, a major loop bubble track and a transfer bubble track comprising permalloy patterns in the same plane.  An external field device propagates the bubbles in the loop bubble tracks.  The transfer bubble track comprising an elongated permalloy pattern having one end adjacent to a normal positional location of a bubble in the minor loop bubble track and its other end adjacent to a normal positional location of a bubble in the major loop bubble track.  An in-plane continuously rotating field generates a first plurality of field vectors having different directions of effective fields in the plane of the permalloy patterns which propagates the bubbles around the major and minor loop bubble tracks.  A control mechanism generating a transfer field vector in the plane of the permalloy patterns for diverting bubbles in one of the loop tracks through the transfer track to the other of the loop tracks.  The arrange-ment eliminates the need for a transfer conductor and hence makes the device simpler and cheaper than prior devices.

Abstract: ABSTRACT OF THE DISCLOSURE         An automatic trap comprising an outer cage and a drum-shaped inner cage rotatably disposed about an axle within the outer cage.  The outer cage has an outer opening which is, in the operative position of the trap, aligned with an inner opening formed in the inner cage to permit entry of a small animal into the inner cage.  Within the inner cage there is pivotally and non-rotatably disposed a treadle means on the axle.  The treadle means engages at its lower, free end a slot in a smooth side wall of the inner cage, thereby locking the inner cage in place when the trap is in its operative position.  The treadle means is then actuated when the animal entering the inner cage contacts the treadle means, thereby releasing it and causing the inner cage to rotate relative to the outer cage by movement of the animal.   The inner cage is then locked by a locking means disposed in the outer cage which locks the inner cage in a position in which the outer and inner openings are no longer aligned.          The animal, seeking to escape, then moves out from the inner cage through the inner opening into the outer cage.  The locking means is then released from engagement with the inner cage when the animal depresses a treadle portion of the locking means.  The inner cage is then caused to rotate back to its operative position by means of a counterweight provid-ed with the inner cage at a point opposite the inner opening, and the inner cage is thereafter locked in its operative position by the treadle means.  The automatic trap is par-ticularly useful in catching small animals such as mice and rats alive and unharmed, one by one.  It is simple in con-struction and operation, and suitable for economical large-scale manufacture.  The trap can be used, without the counterweight and the treadle portion of the locking means, for catching a single small animal.

Abstract: DIGITAL MONITOR               ABSTRACT OF THE DISCLOSURE         A digital monitor for monitoring the operation of a synchronous digital system.   Proper operation of the monitored digital system is determined by storing a predetermined sequence of digital numbers in a memory.  The bit patterns generated by the system being monitored are utilized as addresses to read the stored digital numbers.          After each read cycle the digital number read from the memory is examined to determine if it has the proper value.          If the value is not proper, a memory is set indicating that the system being monitored has malfunctioned,  Additionally, the number of bit patterns checked during each cycle of the system is determined.  If the correct number of patterns are not checked, the memory is also set indicating that a malfunc-tion has occurred.  Apparatus for monitoring a selected number of analog signals such as power supply voltages is also provided.  Either of these tests may be inhibited by signals from the system being monitored or by signals from an external source.
