Abstract: ABSTRACT            The invention relates to a hydraulic device for adjusting the vibration amplitude of eccentric elements especially designed for use on soil and asphalt compaction machines. According to the invention the device consists of a piston 18 enclosed within a hydraulic cylinder 19  the connecting rod 14 of which is rotatably journalled in piston 18 and both ends of which protrude through the ends of cylinder 19. One end of connecting rod 14 is rigidly connected to the eccentric element's drive shaft 11,  which is capable of moving in an axial direction  and the other end of connecting rod 14 is nonrotatably connected to a splined sleeve 15 fitted with a drive motor. The splined coupling permits axial movement between sleeve 15 and connecting rod 14 even while the sleeve is rotating. According to the invention the hydraulic cylinder is of single-acting type and in order to apply a return force on the eccentrics a spring 27 is arranged between one of the sliding bearing bushes 12 inside cylinder 2 and a stop plate 28 rigidly mounted on shaft 11.

Abstract: DISTRIBUTED DATA PROCESSING IN RING-STRUCTURED NETWORKS ARCHITECTED FOR FULL  DUPLEX PEER-TO-PEER OPERATION OF PROCESSING STATIONS AND UNINTERRUPTIBLE TRANSFER OF LONG        DATA RECORDS BETWEEN STATIONS   Abstract Of The Disclosure In a ring-structured data communication network, in which plural data processing systems exchange data and control information on a full duplex peer to peer basis, systems are presently architected to assign at least three I/O subchannels (i.e. at least three device addresses) to respective ring interface adapters.  At least two of these subchannels are dedicated for providing separate input paths from the ring to at least two associated program-assignable areas in their systems main store, and a third of these subchannels is dedicated as an output path from the system's store to the ring.  Collectively, these subchannels can sustain two input transfer processes and one output transfer process concurrently.  One of these input processes is associatable with a locked mode of adapter Operations which provides a non-blockable path for data transfer from a selected (remote) station on the ring to the respective system's main store. In this mode the other input subchannel and the output subchannel permit the system to maintain full duplex communication with other ring stations in respect to network transactions/processes which may require priority attention.  Information is sent on the ring in discrete information frames of variable bit length, each frame acknowledged by a response frame.  In general, response frames have much shorter bit lengths than the information frames, enabling the systems to access the ring more efficiently than they would be able to if response and information frames had equal lengths.

Abstract: A B S T R A C T     An arrangement in a hook orientation means or a separa-ting means, for utilization in a fishing line hauling system. The separating means comprises a pipe having a smaller diameter than the outside cross section of the bow of the hook.  The pipe is bevelled (approx. 20-30°) at one of its ends and split to form a slot extending from the oblique edge face formed at the pipe opening to the other end of the pipe, where a hook guide is mounted to guide the lined up hooks from the slot to a hook magazine.  The oblique edge face formed at the opening changes over into a hook guide plate extending laterally of the pipe opening across the pipe and backwards.  The pipe is mounted on an approximately horizontal base together with the hook guide in such a manner that the pipe opening with the first portion of the slot faces upwards and away from the base.  The slot extends from the pipe opening obliquely downward along the outside of the pipe and toward the other end of the pipe, and it ends at a distance from the base that is equal to or less than half of the pipe diameter.  The hook guide extends obliquely upward from the outlet of the slot and then toward the hook magazine. The pipe and hook guide form an obtuse angle.  A pivoted hook catching finger projects down at the outlet of the slot and is pivotal against a spring force in the direction of the upward inclined portion of the hook guide on the opposite side of the latter in relation to the pipe, the end of hook catching finger after a certain pivotal action being turned above the inclined portion of the hook guide.

Each module includes a plurality of cantilevered print hammers (47) formed print a resilient ferromagnetic material.Each of the print hammers includes an anvil (49) on one face of its cantileveredouter end, adapted to print a dot when the associated hammer is actuated. The modules (45) are mounted on opposite sides of the print line and positioned suchthat the hammers (47) of juxtaposed modules are interleaved and such that the anvils (49) all lie along the print line. Further, each hammer forms part of a magnetic circuit that includes a permanent magnet (51), a post (57) and ferromagnetic paths between the permanent magnet and post. The post supports a coil (59) and is positioned near the cantilevered end of the print hammer (47), on the side opposite of the anvil (49). In the absence of current through the coil (59), the print hammer (47) is attracted to the post by the magnetic field produced by the permanent magnet (51) and, thus, cocked. The cocked hammers (47) are selectively released to create dots by the selective energization of the coils. The selective energization is such that the coils (59) produce a magneticfield that counteracts the magnetic post attraction force created by the permanent magnet (51).

Abstract: "INTERNAL COMBUSTION ENGINE" Abstract of the Disclosure The invention relates to an improved internal combustion engine including a cylinder defining a combustion chamber adapted to receive a combustible mixture for the combustion thereof, and a piston slidably mounted in the cylinder for reciprocating movement between a first limit posi-tion whereat the combustion chamber defines its minimum volume and a second limit position whereat the combustion chamber defines its maximum volume.          According to the invention, a pair of rotatably mounted parallel crank-shafts are arranged equi-distantly relative to the longitudinal axis of the cylinder, each having a crank-arm rotatable about its respective crank-shaft axis.  Coupling means connect the crank-shafts together for synchronising the rotation thereof with the crank-arm of one crank-shaft having an angular advance over the crank-arm of the other crank-shaft.  A rocker member is pivotally connected to the piston for rocking movement about a pivot axis extending normal to the longitudinal axis of the cylinder, and a pair of connecting rods interconnect the rocker member and the respective crank-arms of the crank-shafts with each connecting rod being pivotally connected to the rocker member.  The rocker member together with the connecting rods define a position control means for enabling the rocker member to rock when the piston reaches the first limit position and to thereby maintain the piston substantially stationary at the first limit position for a period of time sufficient to permit the crank-arm of the aforesaid one crank-shaft to move past dead-center.  Thus, substantially maximum com-pression can be achieved in the combustion chamber during a compression stroke of the piston when the piston is at the first limit position while the crank-arm of the aforesaid one crank-shaft is positioned past dead-center such that upon combustion of the combustible mixture maximum thrust can be imparted to the piston.
