Abstract: EXPANDING GATE VALVE WITH POSITION RESPONSIVE INTERLOCK     Abstract of the Disclosure A gate valve (10) has an expanding gate assembly (34) mounted in the valve chamber (14) for movement between open and closed positions. The gate assembly (34) includes a gate (44) connected to a valve stem (28) and a segment (52) is carried by the gate (44). The gate (44) and segment (52) each have wedging surfaces (46 and 54) which permit a wedg-ing action to provide lateral expansion therebetween at the open and closed positions. A rocker arm (80) is pivotally mounted to a side (49) of the gate (44). The rocker arm (80) has a slot (102) with a bearing block (104) slidably received therein. A bearing pin (110) extends from a side (57) of the segment (52) and is journaled in the bearing block (104). A seat skirt (60) is contained within the valve chamber (14) and engages the rocker arm (80) so as to control the ability of the rocker arm (80) to pivot about the gate (44) thereby allowing the gate (44) and segment (52) to expand from each other at a preselected position in the travel of the gate assembly (34). A modification of the structure provides a recess (120) in the sides (49A and 57A) of the gate (44A) and segment (52A). A shoulder (126) protrudes from one side of the rocker arm (80A) and is received within the recess (120) whereby the rocker arm (80A) continues to function as before.

For the method, a polyurethane foam forming mixture is provided, passing said mixture to a dispensing trough wherein partial foaming takes place, the dispensing trough discharging to a moving trough wherein the foam forming mixture expands and cures to form a flexible polyurethane foam.  The inventive method is characterized by providing means for maintaining a generally uniform temperature across the mixture as the mixture passes from the dispensing trough to the moving trough by altering the internal configurations of the dispensing trough. The apparatus comprises in cooperative combination means to supply a foamable foam forming mixture of polyurethane components to a dispensing trough wherein the foam forming mixture partially foams and is discharged to an open topped moving trough wherein the foam forming mixture foams and cures to a flexible polyurethane foam.  The inventive apparatus is characterized by comprising a means within the dispensing trough to provide a generally 28,539A-F     uniform temperature along a cross sectional con-figuration of the foaming mixture as the mixture passes to the moving trough.  The flexible polyure-thane foam produced by the method and from the apparatus of this invention is useful in cushioning applications such as, for example, mattresses and seat cushions.     28,539A-F

Abstract: Abstract of the Disclosure A power amplifier in which a DC power supply is coupled to a load through a switching element, a smooth-ing circuit, and an output amplifying element.  The out-put amplifying element receives an input signal voltage to be amplified.  A voltage detecting circuit is pro-vided which compares a feedback voltage proportional to an output voltage of the smoothing circuit with the input signal voltage to switch the switching element, thereby varying both the power supply voltage of output amplifying element and the load output voltage in accor-dance with the input signal voltage.  As the output voltage of the smoothing circuit is compared with the input signal voltage, the delay of the change of the power supply voltage of the output amplifying element relative to the load output voltage can be reduced, and the generation of distortion and the lowering of effi-ciency can be suppressed.

Abstract: ABSTRACT OF THE DISCLOSURE     A linear actuator includes a ram and a piston separated by a column of hydraulic fluid in a housing. Upward movement of the ram in the housing first seals a finite quantity of hydraulic fluid in the housing cavity.  Continued upward ram movement then causes the piston, and hydraulic fluid beneath it, to move upwardly into a sealed gas chamber to compress a gas and create a source of potential energy.  Release of the force moving the ram upwardly permits the compressed gas above the piston to expel the hydraulic fluid from the chamber against the ram thereby converting the  potential energy in the compressed gas into kinetic energy in the ram.  The hydraulic fluid bears directly against the ram to provide the working stroke of the impact device without the effect of metal fatigue from direct contact between the piston and ram.           BACKGROUND OF THE INVENTION      This invention relates to hydraulic hammers of a type used to break up concrete, street pavement, building walls and the like.  More particularly, it relates to a linear actuator for providing the impacting force on the moil of hydraulic hammers and similar impact devices.  Even though this invention relates specifically to an actuator for impact devices, it might be useful to understand the construction and operation of an impact device per se, such as a hydraulic hammer.  Accordingly, reference is made to my United States Patent No. 4,231,434 dated November 4, 1980.
