Abstract: PROCESS FOR WOOD TREATMENT                        ABSTRACT         The present invention provides a process for the treatment of wood material impregnated with an aqueous ammoniacal solution of water-insoluble treating chemical and having deposits of treating chemical on its surface.  The process comprises submerging the impregnated-wood material in the ammoniacal solution, separating the wood material from the solution and maintaining it in a moist, ammoniacal atmosphere until the wood surface is substantially free of liquid.  In another aspect, this invention relates to a process for producing wood material treated with the ammoniacal solution, where the product has a clean surface.

Abstract: ABSTRACT OF THE DISCLOSURE      This disclosure concerns a spring system between the body of a railroad car and the wheel supporting truck. The spring system includes a coil spring for-absorbing vertical forces and includes a rubber layer spring for absorbing lateral forces, the latter resulting from lateral impact and movement of the railway car along curves in the track.  The last mentioned rubber spring is coaxial with and placed inside the first-mentioned coil spring, thereby minimizing the vertical height of the spring system.  A pair of spring washers extends laterally between the car body and the truck.  The spring washers are held apart by the coil spring.  The rubber spring is divided be-tween a first section above the upper spring washer and the undercarriage o e the car and a second section beneath the lower spring washer and the frame of the truck.  The spring washers have a plurality of troughs for receiving a plurality o-f sets of springs.  For rigidifying purposes, the spring washers on opposite sides of the truck are held together by rigidifying bars.

Abstract: ABSTRACT OF THE DISCLOSURE     A hydraulic apparatus for generating impacts com-prising primary members having striking and control apparatus which is made up of a plunger which moves reciprocatingly, for striking a tool, inside a housing having an intermediate working zone which has a single inner diameter. An interme-diate part making up a piston of the plunger fits therein and has a corresponding single diameter. There is no flow of fluid between these two members and the movement of the plunger is controlled by secondary members and tertiary members which are located in respective housings which make up several chambers, and in which the corresponding plungers are recipro-catingly movable. The apparatus further includes means for discharging the fluid under pressure from within the apparatus for stopping its operation when the tool is not at rest on a workpiece 80 that the main plunger descends inside the housing to a point below its normal lower operating position.

Abstract: HITCH FOR A TRAILER                       ABSTRACT OF THE DISCLOSURE         A hitch for connecting a trailer to a tow vehicle.  The hitch has a beam attached to the tow vehicle for transmitting a load having vertical and horizontal components between the trailer and the tow vehicle. A bearing retained in a guide is connected to the beam by a rack and pinion connection.  A shaft retained by the bearing has a yoke pivotally attached to the end thereof for connecting a ground wheel to the beam.  By changing the position of the rack with respect to the pinion, the distance between the beam and wheel can be adjusted to distribute a selected portion of the vertical component of the load into the wheel.  A linkage connects the tow vehicle to the shaft for maintaining the wheel  in alignment with the tow vehicle to allow the wheel to resist the development of lateral forces between the tow vehicle and the trailer as a function of the vertical component of the load carried by the ground wheel.

Abstract: Case 3367 IMPROVED PLASTIC PULL-UP RIVET     Abstract of the Disclosure An improved plastic blind rivet including a tubular female member having a flange-like head on the outer periphery at the upper open end and a male member having a shank insert-molded within and forming the hollow space of said female member so as to create complimentary intimate shapes between said members.   The female is provided with a plurality of elongated relieved areas in the tubular wall disposed in a longitudinal axial direction. The male member extends through the head and further includes at the lower end of the shank a portion of increased size in contact with the lower end of the female member opposite the head. The shank further includes a plurality of longitudinally disposed relatively flat surfaces carrying locking means, said flat surfaces of the shank being juxtaposed to similar relatively flat surfaces carrying compli-mentary locking means on the interior of the female member so that extraction of the male member out of the female member results in reduction in the length of the female member with consequent expansion of the tubular wall of the member into a petal shape. Work pieces subjected to riveting are thereby fastened between the petals formed by expansion of the female member and the head of said female member while the locking means prevent the male member from being retro-gressively moved back to its initial position.

Abstract: An improved multi-image film cassette holder of the type shown in my United States Patent No. 4,089,019, is combined with an automatic indexing and positioning system to move the film to successive predetermined positions to record a series of images. The holder is adapted to attach to an oscilloscope camera for recording radio isotopic, ultrasonic, computerized axial tomographic, or related types of cathode-ray tube images in medical applications. The holder indexes a sheet of film orthogonally in X-Y directions in its own plane to translate it to successive predetermined positions to record a number, e.g., 4, 6, or 9, separate spaced images, which may be of a standard smaller size, such as 6 x 6 cm. The indexing system employs a pair of servo-motors connected to the cassette holder, preferably via flexible cable drive means. A control and logic panel or console provides for indexing on individual command or in automatic timed sequence. The system can be retrofitted to existing manually operable cassette holders.

Abstract: A METHOD FOR CONTROLLING POWER FLOW BETWEEN         AN ELECTROCHEMICAL CELL AND A POWER GRID                  ABSTRACT OF THE DISCLOSURE       A method for controlling a force-commutated inverter coupled between an electrochemical cell and a power grid for adjusting the magnitude and direction of the electrical energy flowing therebetween.  Both the real power component and the reactive power component of AC electrical energy flow can be independently varied through the switching waveform presented to the intermediately coupled inverter.  A var error signal is derived from a comparison of a var command signal with a signal proportional to the actual reactive power circulating between the inverter and the power grid.  This signal is presented to a voltage controller which essentially varies only the effec-tive magnitude of the fundamental voltage waveform out of the inverter, thereby leaving the real power component substan-tially unaffected.  In a similar manner, a power error signal is derived by a comparison of a power command signal with a signal proportional to the actual real power flowing between the electrochemical cell and the power grid.  This signal is presented to a phase controller which varies only the phase of the fundamental component of the voltage waveform out of the inverter relative to that of the power grid and changes only the real power in proportion thereto, thus leaving the reactive power component substantially unaffected.
