Abstract: ABSTRACT OF THE DISCLOSURE:         A hydraulic percussion mechanism applied for light and heavy boring hammers, rippers-off, etc., used in different branches of the national economy.  The present hydraulic percussion mechanism achieves simultaneously automatic distri-bution of the working fluid and the necessary decreasement of the pressure using the acquired kinetic  energy just for the working stroke of the piston.  The hydraulic percussion mechanism comprises a working cylinder made of outer and intermediate cylinder, and in the intermediate cylinder is placed a cylindrical distributin bush, having two rows of dis-charging front and back openings embracing cylindrical piston with front and tail-end working rings and a cencentrical feed-ing opening with front and back working flanges.  The advan-tages of the invention are that the back working chamber is constantly connected to the pressure fluid current and the piston is moving acceleratingly during the whole working stroke.

Abstract: ABSTRACT   A low insertion force compliant pin is provided for solderless connection to a printed circuit board in which the pin is provided with an enlarged contact portion, a reduced diameter shank, and one or more slots through the contact portion and the shank such that when the pin is inserted into a solder plated-through hole in the board, the contact portion is compressed on itself, thereby to provide a spring-biased contact to the interior plated wall of the hole in the board. The compliant pin also provides anti-overstress protection by compressing on itself. The compliant pin is adapted for use with a number of different hole sizes, with spring bias tension being controlled by the elasticity of the pin material and the length of the slot or slots and the diameter of the enlarged contact portion. the distal end of the pin is provided with a connector body, a solder lug, a wire wrap pin or other termination device so that the compliant pin forms one part of an electrical interconnection system for connection to the plated-through holes of the board.

Abstract: ABSTRACT:          Apparatus for reading an optically readable record carrier.   compact-disc-digital-audio player may be adapted to read optical audio discs in which digital information is stored by controlling the time-base correction circuit in this player by means of a clock signal whose frequency is not a constant reference frequency but a frequency which is locked to the time base of the signal being read. As a result of this both the data signal and the sub code will have the same time base without the necessity of modifying the integra-ted circuits available for the compact-disc digital-audio player.

Abstract: ARTICULATED GONDOLA RAILCAR                ABSTRACT OF THE DISCLOSURE       The railcar includes two car units interconnected by a drawbar.  The drawbar and conventional outboard end couplers are mounted at the locations spaced apart along the longitudinal center lines of the car units.  Each car unit is made up of a gondola carbody and two single axle trucks which support the carbody at four vertical loads support points.  Each carbody includes a depressed center section and a through sill which extends between the drawbar and the coupler within the center section for transmitting buff and draft forces along a rectilinear load path which coincides with the longitudinal center line of the car unit.  Essentially all vertical loads imposed on the center section are transmitted to and borne by the side walls.  The railcar may be of nonarticulated construction, but in either case is particularly suited for fabrication from aluminum.

Abstract: ABSTRACT OF THE DISCLOSURE        With closed respiratory systems, the patient's respiratory tract is tightly connected to a closed volume to which breathing gas is suppli-ed only in the amount taken in by the patient.  To this end, the breathing gas supply must be controlled.  The controlled variable is either the pressure in the ventilating circuit, or the concentration of oxygen or the anesthetic gas in the breathing gas.  A dropping pressure indicates either an increased consumption or a leak.  To avoid insufficient or excessive loading of the patient, it is very important to be able to dis-tinguish consumption from a leak.  The inventive device makes this dis-tinction possible.  The breathing gas amounts are adjusted in the ven-tilating circuit at preset different pressures and are compared with each other, and the leak portion is computed therefrom.

Abstract: ABSTRACT OF THE DISCLOSURE           A field chopper has a main chopping unit provided with a main housing generally extending along an axis and having a radialy outwardly open intake and a radially outwardly open outlet angularly spaced therefrom and a main chopping drum having a plurality of angularly spaced blades and a plurality of angularly spaced wind vances and rotatable about the axis in the housing in a predetermined rotational sense to displace the blades in an orbit.  A stationary blade is secured in the main housing relative to the rotational sense adjacent the down-stream edge of the intake and immediately radially outside the orbit.  The main chopping drum is rotated by a drive to coarsely cut the crop at the stationary blade, to displace the cut crop in the rotational sense back in the main housing, and to propel the cut crop radially outward through the outlet.  The system also has a supplementary chopping unit comprising a supplementary housing opening radially into the housing downstream in the sense from the stationary blade and upstream from the outlet and a supplementary cutter rotatable in the supplementary housing outside the orbit and having radially extending cutting forma-tions. Thus the coarsely cut crop is displaced by the main cutting drum into the supplementary housing.  The supplementary cutter is rotated in the supplementary housing to finely comminute the coarsely cut crop therein and to reintroduce the finely comminuted crop back into the main housing upstream of the out-let.

Abstract: ABSTRACT         A servo tracking system for an optical record uses a pattern of preformed optically detectable uniform servo track marks disposed in parallel spaced apart columns in combination with a beam from a radiation source split by a diffraction grating into three beams having unequal power distribution.  The placement of the beams across the pattern of preformed servo tracks on an optical recording material has one position for writing data by the center beam on an information track while the two outside beams intercept track marks on two adjacent tracks.  For reading recorded data tracks, the beams shift to a second position in which the center beam intercepts marks on a servo track while the two outside beams read two adjacent data tracks.          Because of the unequal power distribution, increasing the energy level of the radiation source causes the intensity of the middle beam during recording to reach a level sufficient to record while the two outside tracking beams remain below that threshold.  The track marks in adjacent columns may be in an offset position with regard to track marks of the adjoining column, to provide self-clocking during recording.
