Abstract: VALVE OPERATOR         ABSTRACT OF THE DISCLOSURE    An actuator for actuating valves and the like which comprises a pair of opposed cylinders, the axes of which are generally perpendicular to a valve stem.  Pistons in the cylinders are connected to the valve stem by toggle links, the pistons being resiliently urged toward the center of the assembly which corresponds to a closed valve position.  To open the valve, a fluid, such as air, is introduced between the pistons, so as to move them away from their rest (valve closed) positions.  A handwheel is provided to manually open the valve by moving the pistons from their rest positions.     A solenoid controlled pneumatic valve may be used to control the supply of air to the actuator.  Either a failure in air pressure or an electrical failure will result in the pistons being urged to the rest positions and also result in closing the connected valve, i.e., the failure mode.

Abstract: SAW CHAIN GRINDER                 ABSTRACT OF THE DISCLOSURE         A grinder for sharpening saw chain cutting teeth includes a base, an arcuate guide arranged on the base, a power-driven rotary grinding wheel mounted on a pivotal motor arm movable with a mounting bracket along the arcuate guide and a releasable, self-centering clamp for holding a segment of a saw chain in position beneath the grinding wheel.  The clamp includes laterally opposed elongate bars which support a saw chain and which are each simultaneously displaceable at equal rates toward a preselected datum line.  The preselected datum line intersects a fixed, reference axis about which the mounting bracket is angularly displaced.  Because the elongate bars are movable equally with respect to the preselected datum line, the lengthwise centerline of a saw chain will always be maintained substantially aligned on the preselected datum line regardless of the width of the chain.  The arcuate guide is an elongate bar having an arcuate guide track which receives the motor arm mounting bracket.  The arcuate guide is pivotal about a pivot axis so that the mounting bracket may be angularly displaced along the arcuate guide and offset at varying distances from the reference axis.

Abstract: SAMPLE AND HOLD FREQUENCY TO VOLTAGE CONVERTER CIRCUIT              ABSTRACT         A sample and hold frequency to voltage convertor circuit particularly suitable for use in automotive applications as a tachometer or other speed indicating device.  The converter uses circuit means, responsive to a periodically varying input signal, to generate first and second pulse trains.  The pulses in the pulse trains have a repetition frequency and duty cycle that varies as a function of the frequency of the input signal.  An integrator is provided for generating a voltage proportional to the duty cycle of the second pulse train.  A transmission gate is controlled by the first pulse train and couples the integrator to a capacitor.  The capacitor is charged or discharged, almost instantaneously, each time the trans-mission gate is rendered conductive by a pulse from the first pulse train.  The capacitor then develops a voltage which is proportional to the frequency of the input signal.

Abstract: AQUACULTURE HABITAT                          Abstract An aquaculture habitat is described for the rearing of post larval crustacia in which a cellular honeycomb structure, pref-erably of opposed cones, provides compartments for the animals and serves as the domicile core.  Individual animals are inserted into the core compartments and the core is sealed with a screen or a mesh on either side of the core.  The screen or mesh is of a size such that water and food may pass through but which restrains the animals.  Cores with screens in place are vertically oriented and horizontally stacked on a false bottom within a tank of water. The tank is provided with food distribution means adjacent the false bottom, and air lift circulation means beneath the food distribution means which, due to the upward rise of the expanding air bubbles, moves the food and freshly filtered and aerated water to the vicinity of the habitats.  Animal feeding is accomplished by food penetration through the screen or by the animal plucking the food from the adjacent water by reaching through the screen. Moreover, habitat cleaning is accomplished by the animal in push-ing out unwanted debris from the compartment through the screen.

Abstract: Abstract A non-adiabatic calorimetric method and apparatus for quantifying the reaction kinetics of thermally unstable chemically reactive materials based on a distinguishing mode of establishing, under near steady state conditions, a thermal gradient across a sample of the chemically reactive material contained between a pair of surfaces maintained at different temperatures, stepwise or rampwise increasing the temperature of one of the surfaces, and quantifying and recording the maximum temperature that is withstood by the sample material at the inception of a self-sustaining exothermic runaway reaction.  The critical temperature of the higher temperature surface is recorded as a function of the lower temperature surface, i.e., the applied thermal gradient.  At least two such critical differential surface temperatures, which are required for calculations, are generated by repeating the experi-ment under differing temperature conditions.  Solution of the steady-state differential equation describing the system, utilizing the experimental data, yields the general kinetics of the runaway reaction of the tested sample material.  The known kinetics allow prediction of the unsteady-state adiabatic or non-adiabatic thermal runaway reaction of the sample for any condition of processing or use.   27,655-F

Abstract: Abstract of the Disclosure An electrophotographic copier has an extended transport path, including a storage for duplex functions, for copying documents which may be reproduced, to a se-lectable number of copies, from a master.  The master is positioned first at an imaging station, so that the de-sired number of image transfers to copies can be made. The master document transport system recirculates the imaged master, holding it at a storage station spaced apart from the image station, while a second master is positioned at the image station.  The system need not be delayed by requiring that all of the copy documents reach an exit position before the second master is inserted. Moreover if a jam occurs in any of a number of modes of operation the system is able to recall one or two masters as needed to complete the run in most expeditious fashion.  By employing a first run adjacent the image station and a second run moving in the opposite direction and adjacent thereto, documents at the storage station may selectively be returned to the image station, to the entry mechanism for the system, or may be exited from the system. When duplex copies are being made from simplex or duplex masters, for example, a jam occurring when copying on the second side is followed by completing the copies in the duplex bin, then recalling the first master to undertake duplex copying of the number of added copies needed to make up the number lost in the jam.  The system can there-fore operate in semiautomatic or automatic document feeding modes to provide simplex copies, duplex copies from simplex masters, or duplex copies of duplex masters.

The punch is formed with co-axial extension portions of successively smaller diameter. Thus, the first extension portion is closely fitted within the blank, while the second extension portion is aligned within the die throat as the punch end pushes the blank towards and through the die throat to thereby form the tube lead end thickened end portion. Further pushing of the blank by the punch takes place while the first extension is aligned with the die throat to thereby extrude the relatively thin wall middle portion of the tube. Next, the punch is removed, and a second blank is inserted within the die against the trailing end of the first blank. The punch is reinserted to press the second blank, which in turn pushes the first blank through the die throat while the third extension is positioned in the die throat to form an inwardly extending annular ring-like portion within the metal tube. Thereafter, further pressure by the punch, while the second die extension is again aligned within the die throat, simultaneously extrudes the metal tube trailing end thickened portion and simultaneously, the lead end thickened portion on the tube produced from the second blank.
