Abstract: SOLID-STATE HID LAMP DIMMER     ABSTRACT OF THE DISCLOSURE         Lighting control apparatus for controlling the light intensity of high-intensity-discharge (HID) lamps operated from an AC source while eliminating the tendency for such lamps to extinguish during the dimming thereof.      The apparatus comprises a variable reactive ballast controlled with respect to its reactance by a solid-state switching device which is responsive to a timed control signal provided by a signal generating device operating from the same AC source.  A lamp voltage sensing device develops a feedback signal which varies in accordance with the voltage drop across the lamps being ballasted.  A signal sensing and overriding device combines the feedback signal and the timed controlled signal and causes the feedback signal to override the timed control signal before the lamp voltage reaches such value as might cause the lamp to extinguish.  In this manner, when the lamp is dimmed and its voltage tends to rise, the voltage rise is automatically compensated for by an increase in power to the lamp which in turn decreases the voltage drop across the lamp so that the tendency of the lamp to extinguish during dimming thereof is eliminated.

Abstract: ABSTRACT OF THE DISCLOSURE A novel control circuit for heating and heating/cooling systems wherein in a heating mode the circuit controls a valve means comprising a main valve and a modulating valve through which gas is supplied to a burner.          The main valve is a normally closed, solenoid-actuated type which opens when its coil is energized, and energization of its solenoid is controlled by a pair of normally open relay contact connected in series. One of the con-tacts closes when the temperature in the space being heated drops below a preset temperature. The other contact remains closed so long as the tem-perature in the space being heated remains below a maximum limit. In a heating/cooling system the circuit is selectively operatively coupled with the valve means and a refrigeration unit. When heating is selected, the circuit operates as mentioned above. In cooling, a cooling solenoid of the refriger-ation unit is energized when the temperature in the space being cooled rises above a preset temperature.  A blower and blower control are also controlled such that the blower can operate either automatically whenever the refriger-ation unit operates or continuously in either heating, cooling, or off. The circuit can be installed with a minimum number of wires connecting the temperature settling and sensing control unit with the control circuit module, A feedback circuit in the control circuit prevents the control circuit from pulsing the refrigeration unit when the desired temperature in the space being cooled is reached.

Abstract: ABSTRACT OF THE DISCLOSURE    This vacuum-type circuit interrupter in a high current interrupter rated for interrupting currents of 35,000 amperes r.m.s. or higher.  Despite this high current interrupting requirement, each of its disc-shaped contacts can be made from an exceptionally small and thin blank because these contacts are of beryllium and each has a flat surface, without the usual central recess, extending from its center to a perimeter located radially between the outer periphery of the contact and the outer periphery of the inner and of the associated contact rod.  On this flat surface of beryllium, contact-engagement occurs and arcs are initiated during interruption.  Each contact rod is joined to its associated beryllium contact by means of brazed joint, a portion of which is accommodated in a very shallow recess on the back surface of the contact.

Heat or a combination of heat and pH reversal can also be employed.  Flavours and other additions added to the blood or other material before decolorization are locked in the resulting product.  The decolorized material can be canned as a mince-like product or mixed with other foodstuffs.
