Abstract: DRUM BRAKE HAVING PARKING MECHANISM      ABSTRACT OF THE DISCLOSURE A drum brake assembly includes a pair of brake shoes which are movable to a braking position by a hydraulic actuator.  In order to maintain the pair of brake shoes adjacent the drum an adjuster is disposed between the pair of brake shoes opposite the hydraulic actuator.  The adjuster carries a parking mechanism to manually move the pair of brake shoes to the braking position independently of the hydraulic actuator.  The parking mechanism comprises a pair of levers which are pivotally connected to pro-jections on the adjuster and the levers oppose one of the pair of brake shoes such that pivoting of the pair of levers moves the adjuster and the other brake shoe away from the one brake shoe.  A spacer and a washer are dis-posed between the one brake shoe and abutment surfaces on each pair of levers and the adjuster movably supports the spacer and the washer.

Abstract: ABSTRACT OF THE DISCLOSURE A cooking oven having both microwave and electrical resistance heating element and which fully utilize the capabilities of a limited-capability power source to achieve the shortest possible cooking time.  The oven has a microwave energy generating system which requires less than all of the available current when operated at its full rated power level, and an electrical resistance heating element which requires substantially all of the available current when operated at is full rated power level.  The oven also has apparatus for at least successively energizing the microwave energy generating system and the electrical resistance heating element at their respective full rated power levels.  Additionally, there is apparatus for energizing the electrical resistance heating element from the power source at a reduced power level when the microwave energy generating system is energized at its full rated power level. The reduced power level is selected such that the total of the currents required to operate the microwave energy generating system at its full rated power level and to operate the electrical resistance heating element at the reduced power level is no greater than and, preferably substantially equal to, the power source capability.

Abstract: This invention relates to an improved injection molding filter assembly to be located between the molding machine and the mold.  The assembly has an elongated inner torpedo member with a generally cylindrical outer surface which is centrally located in a passage through a hollow outer member.  The passage is defined by a generally cylindrical inner wall which is interrupted by an even number of inwardly opening longitudinally extending channels.  Inlet channels extending from the inlet of the assembly and dead ending adjacent the outlet alternate with outlet channels extending from the outlet of the assembly and dead ending adjacent the inlet.  Filtering apertures are formed between the outer surface of the torpedo member and the lands between the inlet and outlet channels through which the melt flows from the inlet channels to the outlet channels.  A single elongated aperture may be formed at each land or a plurality of smaller apertures may be formed by providing alternating laterally extending ridges and grooves on the inner surfaces of the lands and/or on the outer surface of the torpedo member.  Contaminants which are too large to pass through the filtering apertures accumulate adjacent the dead ends of the inlet channels.  The outer member has a collar portion which may be detached to take out the torpedo member for periodic removal of accumulated contaminants.  The location of the channels in the outer member provides improved heat flow characteristics and allows the width of the filtering slits to be quickly and easily changed by substituting a relatively inexpensive torpedo member having a different diameter.

Abstract: ABSTRACT   A pressure-regulator for gaseous and liquid flow-media is disclosed. The regulator has a main valve arranged between an inlet and an outlet for the flow-medium, the body of the valve closing the valve-seat, or opening it to different degrees, depending upon the regulating condition.  In a control pressure chamber, the pressure acts upon the main valve-body and the chamber is connected, on the one hand, through a choke, to the inlet and, on the other hand, through a control-valve, to a de-aerating chamber.  There is a rated-value transmitter, the setting of which applies to the body of the control valve a specific force which urges it, against the pressure obtaining in the control-pressure chamber, in the direction of closing.  There is also a device for detecting and feeding back the actual value present at the outlet.  The invention is characterized in that a return-pressure chamber is provided, the pressure in which acts, against the pressure obtaining in the control-pressure chamber, upon the main valve body, and which is connected, on the one hand, through a choke, to the outlet and, on the other hand, through an adjustable choke, to the de-aerating chamber.

A first core unit is formed of a reducible material molded upon the preformed liner, which first core unit includes a first main core portion which partially occupies the bore and a port core portion which extends through the port.  A second core unit is formed of the reducible material separately from the first core unit and is assembled upon the cylinder liner, which second core unit includes a second main core portion in the bore and in mating alignment with the first main core portion, thereby forming a composite core assemblage.  The composite core assemblage is placed into a cylinder block mold, and molten metal is caused to enter the cylinder block mold, thereby forming a cylinder block surrounding the composite core assemblage.  The reducible material of the first and second core structures is then reduced to open the interior bore and the associated port, thereby forming a cylinder block having a cast body portion in which the cylinder liner and associated exhaust and transfer passages are all integrally cast.

Abstract: ABSTRACT OF THE DISCLOSURE      A beam feedback synchronization system for optical sweeping apparatuses is disclosed.  The system includes a multi-faceted rotating reflection mirror which acts or. a collimated light beam such as a laser beam to cause it to sweep periodically in parallel straight lines across a rotating photoconducting drum.  A portion of the light beam is split off and caused to sweep across an equispaced linear array of fiber optic apertures held in place by a fiber optic assembly.  The light entering the fiber optic apertures is carried along fiber optic elements to one or more photodetectors which generate periodic electrical signals in response thereto.  the frequency of occurrence of the electrical signals from the photodetector is a measure of the velocity of the sweeping light beam across the fiber optic array.  A phase locked loop circuit connected to the photoaetector(s) provides a character clock signal which is synchronized to the electrical signals received from the photodetector and compensates for variations in the speed of the light beam across the fiber optic array. The phase locked loop further comprises a fast synchronization circuit which provides immediate synchronization between the character clock signal and the first electrical signal occurring at the beginning of a new light beam sweep.  In addition, hold circuitry is provided which holds the frequency of the character clock signal coming from the phase locked loop constant during the dead time occurring between laser light beam sweeps.
