Abstract: - 26 -             RCA 73,308 Abstract of the Disclosure A biasing circuit is provided for stabilizing the gain of a transistor amplifier against variations in temperature.  The amplifier includes an input terminal and a transistor having a base-to-emitter junction coupled between the input terminal and the second terminal of a two-terminal source of supply potential.  The biasing circuit is coupled between the two supply terminals and includes a resistor coupled to the first terminal, a semiconductor rectifying junction coupled between the input terminal of the amplifier and the second supply terminal ,and the parallel combination of the collector-to-emitter path of a second transistor and a voltage divider coupled between the resistor and the rectifying junction.  The base of the second transistor is coupled to an intermediate tap of the voltage divider.  As the temperature of the circuit increases, the gm of the amplifying transistor decreases.  The biasing circuit conducts an increasing amount of current to the amplifier as the operating temperature of the circuit increases. This increase in biasing current causes an increase in the collector current of the amplifying transistor, which stabilizes the gm and hence the gain of the amplifier.

Abstract: FIRE-FIGHTING APPARATUS                  ABSTRACT OF THE DISCLOSURE    A fire-fighting apparatus comprising a cabinet having a door affording access to a water hose, operating valve and fire extinguisher.  The cabinet is divided into three compartments, the first containing a fire hose, the second a valve assembly connected to the fire hose, and the third a chemical ex-tinguisher.  A cover plate is hingedly mounted to overlie the valve assembly, and more particularly the operating handle. The cover plate is spring urged to uncover the handle; however, it is engaged by the fire hose when in its compartment to hold the cover plate in overlying relation to the handle.  Thus, unless the fire hose is withdrawn from its compartment, the cover plate overlies the handle and serves as a safeguard against operation of the handle while the fire hose is still in the compartment.     An electrical switch is activated upon operation of the handle.  The switch may be connected to any suitable alarm device which is activated when the water valve is turned "on".

A three-phase balanced overload or even a fault will cause much less ripple content than a single-phase  overload  condition.   A  circuit  consisting  of  a resistance  and  capacitance  in  series  is  connected  in parallel with the plug resistor,  and,  the voltage drop across the resistance is used to initiate tripping if the signal  exceeds  a predetermined magnitude,  and  after  a selectable optional time delay.  There is no need for an additional external power source to accomplish tripping. The apparatus desirably responds to single-phase faults and does not  respond to motor inrush currents such as during starting.

Abstract: Abstract of the Disclosure In a central liquid replenishment system for accumulator cells (1,2) each cell is connected to an inflow conduit (9) for battery liquid and comprises means (7,8,10) permitting the battery liquid to flow past the cell when the electrolyte level in the cell is normal. The inflow conduit communicates with a central supply (19) for battery liquid and with a suction device generating an underpressure in the system, causing battery liquid to flow to the cells. The replenishment container (16) for battery liquid is arranged at a level such that the liquid level in the container is substantially the same as in the cells. The pressure conditions in the accumulator, and thus its replenishment characteristics will therefore be independent of the relative positions of the central supply and the accumulator.

Abstract: ABSTRACT OF THE DISCLOSURE         An orifice plate for a glass fiber drawing bushing having a flat undersurface and a number of orifices formed through the orifice plate, in which longitudinal and transverse parallel grooves are formed on the undersurface of the orifice plate in such a way that the undersurface is divided by the longitudinal and transverse grooves into a number of square sections within each of which is located one of orifices.  In this way the orifice plate is deformed just as having tip nozzles in a shape of quadrangular prism and therefore the pitch of orifices arranged in the orifice plate may be made as small as in conventional tip nozzles.          When the grooves are formed in the undersurface of a closely spaced orifice plate which requires to blow cooling air against the undersurface of the orifice plate so as to prevent flooding of the undersurface by molten glass and ensure stable glass fiber drawing operation, the orifice plate may be used for drawing finer glass fibers which cannot be drawn with conventional closely spaced orifice plates without grooves.

Abstract: 22,825 Abstract of the Disclosure During "ON" operation, the lengths of the arms of a toggle are essentially fixed; during "TRIP" operation, the length of at least one arm is effectively shortened. The toggle operates, in "ON" condition, with one arm pivotally coupled to a second arm about a fixed pivot point adjacent to a channel with respect to the second arm.  In "TRIP" condition, the one arm is pivotally coup-led to the other arm about at least one pivot point lying within the channel.  A spring couples the two arms which are pivoted together: in "normal" condition, one arm is pivoted about a substantially fixed point with respect to the other arm; in "TRIP" condition, one arm is pivoted about a locus of points with respect to the second arm distant from the substantially fixed point.  A stationary contact is held by an insulated circuit breaker housing A handle is pivoted about a fixed pivot point on the housing and is limited in arcuate motion by the housing A contact arm, having a contact affixed thereto, has a pocket with at least one corner, an attachment means, and a projection.  A latch normally blocks one corner of the pocket so as to provide a corner opening for reception of a portion of a link which extends from the handle.  The latch, when actuated, unblocks the corner to permit the portion of the link to exit from the opening.  A spring couples the attachment means to the housing so as to urge the contact arm toward the fixed pivot point.  In "ON" condition, the latch blocks the one corner of the pocket and the contacts are engaged.  Upon actuation of the latch, the one corner unblocks, and the portion of the link exits from the corner opening, whereupon the projection engages with a housing barrier, causing the contact arm to at least partially pivot thereabout, opening the contacts.
