Abstract: ABSTRACT          An impactor assembly in which a hammer piston is reciprocably moveable through alternate work strokes and return strokes is provided.  The impactor assembly has a body with an elongated bore.  The hammer piston is axially slidable within this bore.  A closed fluid pressure drive system is provided which continously biases the hammer piston in one axial direction within the bore.  A fluid flow path, which includes a valve, is formed within the body for selectively controlling the flow of hyraulic fluid to intermittently bias the hammer piston in a second axial direction which is opposite the first axial direction thereby effecting alternate strokes of the hammer piston within the bore. The valve includes an integral actuator which is capable of cycling the valve to intermittently bias the hammer piston against the drive system.  The actutator is in continuous cooperation with the drive system to provide the impetus for cycling the valve.

Abstract: ABSTRACT OF THE DISCLOSURE         In a rotary machine mounted on a rotary shaft journaled in journal bearings, a source of un-usual vibration of the rotary machine is identified on the basis of the results of the steps of (1) subjecting a shaft vibration signal to frequency analysis for analyzing its frequency distribution, and (2) analyzing the amplitude of the shaft vibration signal and the variation rate of a phase signal of a component related to the shaft rotation frequency among the frequency components of the shaft vibration signal.  The present invention is usefully applicable to diagnosis of vibra-tion of a rotary shaft of a large-size turbine or a generator in a power plant by continuously monitoring the shaft vibration for immediately automatically detecting unusual vibration of the rotary machine in the event of occurrence of such unusual vibration.  The usefulness is more enhanced when the signal indicative of vibration of the rotary shaft is converted into a digital signal to be analyzed by a digital computer which identifies the source of unusual vibration.

Abstract: ABSTRACT OF THE DISCLOSURE:    Photography, particularly, a method of modifying slide trans-parencies so as to eliminate distortion and to provide uniform illumination in  oblique projection, for example, upon rear view screens. The method of modifying slide transparencies includes sup-porting the object to be photographed at an angle with respect to the optical path of the camera; selectively illuminating the ob-ject to be photographed such that the portion farthest from the camera receives the greatest portion of the light with the rest of the object being gradually and continuously less illuminated so the portion nearest the camera receives the least light; and, taking a picture of the object, such that the transparency defines the object being photographed in trapezoidal form with the wider base being the least illuminated and the narrow apex being the . greatest illuminated.

Abstract: RCA 74,595 Abstract Accumulated foreign material on the signal pickup stylus of a video disc player tends to degrade the quality of the recovered information signal.  The recovered information signal is detected and the nominal amplitude of the recovered signal is compared against a reference amplitude.  The occurrence of a decrease in recovered signal amplitude below the level of the reference causes a comparator to generate a control or trigger pulse.  The control pulse activates a pulse generator to produce a predetermined pulse sequence which is applied to a stylus deflection transducer to move the stylus fore and aft radially across the disc and thereby dislodge the foreign material from the pickup stylus.

Abstract: A process and device for selectively separating particles from a suspension is disclosed. The process involves: introducing the suspension into a rotating separation chamber in which the flow is regulated so that the angular velocity of the suspension is maintained slightly higher than the angular velocity of the wall of the chamber. The bulk of the flow of the suspension treated is removed from the separation chamber from a peripheral area. The following fractions are removed separately, simultaneously, and if necessary continuously. The heavy fraction is removed from a zone near of the sidewall; the light fraction is removed from a zone nearer of the longitudinal axis of the chamber, than the heavy fraction outlet and if desired, an intermediate fraction may be removed from at least one separate intermediate zone between the light fraction outlet and the heavy fraction outlet. The apparatus comprises a separation chamber having a longitudinal axis, sidewalls and two ends; inlets through the first end for introducing suspension and auxiliary fluid; rotating means for deviating suspension and auxiliary fluid towards the sidewalls outlets for the heavy and the intermediate fractions in the second end of the separation zone; rotating means to collect the effluents from areas nearer the sidewalls to their respective outlets; and a light fraction outlet is provided in the first end of the separation chamber and is colinearly aligned with the longitudinal axis. Rotating means are provided to rotate the separation chamber around its longitudinal axis. Numerous alternative embodiments are described.

Abstract: LOAD SENSING STEERING                        Abstract Fluid in the relatively long lines between a control valve and a fluid actuator can become overly viscous in cold weather.  Fluid is circulated through such lines, at least during cold weather, even when the fluid actuator is not being used.  This flowing is discontinued in response to shifting of the control valve to a position where it motivates the actuator and in response to pressure in the circulating path exceeding a selected level.

Abstract: ABSTRACT OF THE DISCLOSURE       An adjustable wide-slit extrusion nozzle contains a distributor channel having a straight exit edge and a predetermined cross-section taken from the supply port for the nozzle to one end thereof.  At least one choker bar is placed between the distributor channel and the nozzle mouth, the choker bar having a damming area of predetermined length dimensions in the direction of flow for given distances from the channel end.  The damming area rises above the remaining surface area of the insert, before or behind the damming area surface, in a uniform jump of predetermined size relative to the exit height of the nozzle and is a height-adjustable parallel faced bar mounted in the nozzle.  This construction overcomes the problems of prior art extrusion nozzles by ensuring that a uniform amount of material is extruded from every point of the nozzle mount at any moment thereby producing an even film or ribbon.

Abstract: Title METHOD AND APPARATUS FOR CALORIMETRIC     DIFFERENTIAL THERMAL ANALYSIS  Abstract of the Disclosure A calorimetric differential thermal analyzer uses a planar thermoelectric sheet as its major heat flow path for transferring heat from a heat source to both the reference and sample positions.  The heat source is connected to each of the positions by equivalent thermal paths formed by the sheet itself. These paths to each test position are made thermally equivalent by making them geometrically similar and forming isothermal boundaries on the sheet itself between each of the test positions. These isothermal boundaries are connected to the heat source and formed of a material having a high thermal conductance.        The thermal equivalency of the paths may be enhanced by removing portions of the sheetlike material to form well defined patterns of heat flow in the sheet; e.g., structures in which the sheet is formed into radial arms in a wheel-like array with each test position being on a different spoke of the wheel.  Heat from the heat source may be applied through the hub of the wheel or the rim of the wheel or both, the hub and rim being in good thermal contact with isothermal boundaries having a high thermal conductance.
