Abstract: ABSTRACT OF THE DISCLOSURE   A circuit for operating a discharge lamp at a low frequency AC voltage while repetitively interrupting at a high frequency the voltage component to be applied to the lamp.  The circuit includes at least one switching transistor for repetitively interrupting the voltage to be applied to the lamp at the high frequency, for example, 40 KHz so as to allow the use of a light and less bulky inductor as the current limiting conductor to be connected in series with the lamp.  A bridge inverter is provided to have at least one pair of switching transistors for alternately reversing a DC voltage to apply the resulting AC voltage to the lamp at the low frequency, for example, 100 Hz low enough to stably operate the lamp without suffering from acoustic resonance.  The high frequency component is bypassed through a bypass capacitor connected in parallel with the lamp.  By reason of the inverter producing the low frequency AC voltage, the circuit requires all-off period during which the switching transistors of the bridge inverter are simultaneously off for preventing the short circuiting of the power source.  An oscillation-inducing inductor is connected in series with the lamp in parallel relation to the bypass capacitor so as to form a series oscillating circuit which causes to flow an alternating oscillating current to the lamp circuit throughout the all-off period.  The resulting oscillating lamp current continues for a longer time to thereby retard the deionization of the lamp.  Accordingly, the all-off time can be extended to such an extent as to give greater flexibility in designing the circuit which is free from short circuiting of the power source as well as from the increased reignition voltage.

Abstract: Abstract of the Disclosure An inline dispersal valve is constructed with a chamber into which a material to be dispersed into a fluid stream may be inserted. A first fluid deflector is used to direct fluid away from the fluid stream into the chamber to permit the fluid to absorb the dispersant, and a second fluid deflector, oppositely facing, that directs the fluid back into the fluid stream after it has passed through the chamber. The bottom of the chamber has a pair of openings in a line with each other which have an axis that i  substantially normal to the axis of the fluid flow in a main stream.  A rotatable plate having a pair of apertures of a specially designed  tear drop shape controls the amount of fluid that flows through the chamber in accordance with the amount of available area to the fluid stream due to the alignment of the apertures with respect to inlet and outlet ports, respectively. The plate which contains the apertures is preferably a circular disc which carries a curved row of rack teeth. In one embodiment the rack teeth mesh with a spur gear which is coupled to a shaft that has a control knob on its outer end.  As the control knob is rotated the spur gear rolls along the curved rack, causing the control plate to rotate.  In a second embodiment a control plug is directly attached to the apertures such that when the plug is rotated the amount of fluid exposed to the apertures is increased or decreased directly and a chemical canister which may be keyed to the housing to prevent insertion of improper chemicals into the dispersal valve.

Abstract: Apparatus (10) for automatically dispensing a liquid treatment chemical (12) from a replaceable supply bottle (14) into an intermittently flowing liquid stream (22) such as a recirculating water supply for a refrigeration system. The apparatus has a feeder chamber (16) into which the liquid stream (22) flows which is periodically emptied by a siphon tube (18) when the liquid reaches a level sufficient to establish a siphon effect in the siphon tube (18). The rising level of liquid (22) in the chamber (16) also actuates, by means of a float (24), the valve portion (31) of a closure assembly (30) on the inverted top of the supply bottle (14). The valve portion (31) is fed by a capillary tube (50) and dispenses a predetermined, very small quantity of chemical each time it is actuated. The valve portion (31) is prevented from becoming clogged by chemical crystals during inactive periods by being mounted so that its surface will be flushed each cycle by the water (22) which rises in the feeder chamber (16).

Abstract: Glass shapes and sheets are cut directly from a heated glass ribbon while maintaining the optical quality of the cut glass. A float glass ribbon is removed from a glass forming chamber and prior to annealing, a line of cut is heated to its softening temperature. A blade arrangement thereafter penetrates the glass along the heated line of cut to sever the glass. The cut glass edge is shaped after cutting while the edge is still at the softening temperature. During the line heating and cutting operation, the overall glass temperature is maintained above the strain point of the glass.
