Abstract: ABSTRACT OF THE DISCLOSURE           A circuit breaker operating mechanism is disclosed having the opening spring thereof disposed within the clos-ing spring thereof.  The closing spring has one end thereof affixed to the operating mechanism support base while the other end thereof is movable relative to the support base for being charged and discharged.  The encircled opening spring has a first end thereof which is affixed relative to the mechanism support frame.  The other end of the opening spring is movable.  However, the latter movable end is held temporarily fixed relative to the support base during a charging operation for the closing spring so that the open-ing spring will be charged with the charging of the closing spring.  When a circuit breaker opening operation is neces-sitated, the non-fixed end of the opening spring is re-leased, thus allowing the opening spring to discharge while the closing spring remains charged.  Consequently, the charging operations for both the closing spring and the enclosed opening spring are in compression and may be simul-taneous.

Abstract: ABSTRACT OF THE DISCLOSURE Viewer preference adjustment of saturation is realized in a VIR-controlled color television receiver by provision of a closed loop control circuit exclusive of the RGB matrix. During the presence of the VIR signal a control signal is generated within the closed loop that controls the chrominance-to-luminance ratio of the chrominance and luminance signals applied to the RGB matrix and to a blue matrix contained within the closed loop.  Adjustment of the level of either the luminance signal or the chrominance signal applied to the blue matrix affects the control signal which in turn adjusts the chrominance-to-luminance ratio to compensate and thereby bring about a shift in the levels of the red, green and the blue signals at the output of the RGB matrix to change the saturation of the color picture.

Abstract: LOW WEIGHT RECIPROCATING ENGINE               ABSTRACT OF THE DISCLOSURE      An internal combustion V-8 engine is disclosed having an aluminum semi-permanent mold head cast by a low-pressure die-cast process and an iron block cast by the evaporative casting method.  The block and head have con-trolled thickness walls throughout to optimally lower the metal/working volume ratio of the engine.  The block employs barrel cylinder walls cast integrally and unsupported except at the barrel ends and at a siamese connection between adjacent barrels; the barrels are maintained under a predetermined level of compression to eliminate fatigue failure and suppress sound.  The block is sand cast and the head is totally formed with a three piece die and one sand core cluster, except for one passage which is drilled sub sequent to casting.  The engine is reduced in weight by at least 20% over conventional comparable engines; torque and horsepower is improved even though the cooling system capacity has been reduced to less than half that of a conventional cooling system.

Abstract: ABSTRACT OF THE DISCLOSURE       This invention relates to a process for preparing a raw cement mixture with the use of a calcium-orthosilicate slime resulting from a complex processing of a high-silica aluminous raw material containing at least 20% by weight of silica to alumina, soda, potash and cement as well as with the use of a calcium-containing component and, when requir-ed, purpose additives. The process comprises a repeated washing of said calcium-orthosilicate slime with water al-ternating with separation of the slime from the washing wat-er, followed by grinding of the slime. Between two any al-ternating operations of washing and separation of the slime from the washing water a preliminary grinding of the slime is effected. Said preliminary and/or repeated grinding of the slime is effected simultaneously with mixing of said slime with said calcium-containing component and, when re-quired, with said purpose additives. The process makes it possible to reduce the residual content of alkalis in the slime to 1-2% by weight and that of alumina - to 1.5-2.8% by weight. It also eliminates thickening and setting of the slime and cement raw mixture upon transportation and stor-age thereof. Mechanical strength of cement produced from the thus-prepared raw mixture is increased by 15-25%. The yield of alumina (in the production of alumina) is increased by 0.5-3%; the total yield of soda and potash (in the soda -potash manufacture) is increased by 0.5-2.5.

The bracket includes a base portion having a front wall and opposed parallel side walls and opposed parallel upper and lower end walls joined to the rear surface of the front wall to define a cavity.  The free ends of the upper and lower end walls are arcuate, curving inwardly from the opposite side walls toward the front wall for accommodating a  cylin-drical post or the like support member.  A hollow support arm extends from the front surface of the front wall of the base portion to the housing and carries electrical wiring between the housing and the base portion of the mounting bracket.

A gasket received in the base portion is held between shoulders formed on the rear surface of the front wall between the screw receiving apertures.          Apertures on opposite sides of the upper mounting screw aperture, between the upper shoulder and upper end wall, permit electrical wiring to pass outwardly of the base portion for externally wiring the light fixture.
