Abstract: Abstract of the Disclosure An electrohydraulic control system which includes first and second electrically controlled fully variable hydraulic pumps adapted to be driven by the vehicle engine.  In the specific embodiment of the invention herein disclosed, the first pump is coupled to the steering and braking control valves, and the second pump is coupled to the bucket and hoist control valves.  An electrically controlled poppet valve selectively interconnects the respective pump outputs.          Operator-responsive controllers, namely a bucket/hoist joy-stick controller, a vehicle propulsion controller and a steering controller, provide associated electrical signals as respective functions of operator demand.  Electrically operated valves control application of hydraulic fluid to the bucket and hoist drive mechanisms, and pressure and position sensors are connected to such valves and actuating mechanisms.  An electronic controller receives inputs in-dicative of operator demands, pump outputs, and operation at the hoist and bucket, and selectively controls or modulates the cartridge valve, the pumps, and the hoist and bucket valves for operation at optimum efficiency.

Abstract: A B S T R A C T     IMPROVED TIME SLOT ARRANGEMENTS FOR LOCAL AREA NETWORK SYSTEMS     In local area networks (LAN's) which are required to operate in duplex mode it is necessary for the common communication medium to be operated in a t.d.m.  manner.  Because the LAN has no common equipment, every station is arranged to contain its own control circuitry and crystal controlled clocking system to produce time slot markers.  The system is organised so that each time slot comprises an active period for data or speech transmission or contention resolution, followed by a transit period in which the data or speech reaches the destination.  Ideally time slot markers occur simultaneously in both stations and for intermediate stations there is a tolerance which reaches a maximum at the midway point of the network communication medium.  The multiplexing system arranges that the time slots are packed as closely together as the delay between most separated stations will allow.  The near simultaneous occurrance of time slot markers is maintained by all stations whether busy or free by observing the timing of traffic on the communication medium and adjusting the timing of the station time slot marker to occur in the time between data or speech bursts of existing traffic.

Abstract: ABSTRACT         In any puzzle game, the aim is to place in proper order all the pieces which form a design, or the different color components of mechanical games, after having mixed them.          According to the present invention, the pieces are tabs which are also colored, however,they circulate inside channels engraved on each side of a body, and they can only be displaced by means of wheels which partly occupy these channels.  The body is closed on both sides by means of a cover which allows the outer part of the wheels to extend therethrough: by rotating the outer part with the tip of the fingers, the tabs can be displaced from one channel to the other.  It should be born in mind that the body, the wheels and the covers are made of transparent plastic material which enable  to identify the opaque colors of the tabs, and facilitate the study of the game at a glance.

Abstract: ADDITIVE-CONTAINING POLYOLEFIN BEADS            AND PROCESS FOR THEIR PREPARATION                           ABSTRACT     The invention provides an additive-containing polyole-fin having an inner bead of a first polyolefin and an outer adherant coating of a second polyolefin encapsulating the additive.     BACKGROUND OF THE INVENTION        Recently new catalysts have been developed which are far more active than conventional catalysts in the polymerization of alpha-olefins. Briefly described, these catalysts are comprised of a titanium halide catalyst component supported on magnesium dihalide and an alkylaluminum compound, which can be present as a complex with an electron donor compound. These catalyst com-ponents have been described in the patent literature, e.g., in U.S. Pat. Nos. 3,830,787, 3,953,414, 4,051,313, 4,115,319, 4,149,990, 4,218,339, 4,220,554, 4,226,741 and 4,263,169 Catalysts of these types function well in the homo and copolymerization of alpha-olefins having from 2 to 18 carbon atoms particularly when the process is carried out under slurry con-ditions using a liquid hydrocarbon diluent, which can be liquid monomer, inert hydrocarbon or a mixture of such compounds.        The productivities obtained with these new catalysts are extremely high resulting in polymers containing such small quan-tities of residual catalyst that the conventional deashing step can be dispensed with.      Further improvements in overall process economics have been achieved by the use of spherical or spheroidal-shaped supported titanium halide catalyst compounds in slurry polymerizations of

Abstract: Title Drive Line Slip Joint Assembly Abstract of the Disclosure A drive line joint assembly 10 has splined driving and driven members 13,20, one of which has a protuberance 36 which extends axially along a spline 16,18 thereof to insure the absence of radial tolerance for balancing purposes.  In a preferred form, a forged steel spline 16 has a resilient coating 40 bonded thereto, the coating preferably of a nylon or of other material having comparable low friction quality.  The resilient protuberance is an integral part of the latter low friction coating and is formed by a broaching tool after the coating material has been applied to the spline.  In a preferred embodiment, the protuberance extends only 0.001 to 0.003 inch above the surface of the coating, wherein the coating has a thickness in the range of 0.007 to 0.014 inch over the steel body portion of the spline.  At least three of the protuberances are preferred, each circumferentially spaced from the other.  The protuberances are utilized to take up all radial slack between driving and driven members of the drive line joint assembly, thereby allowing for no radial movement of one member with respect to the other.

Abstract: AUTOMATIC LINE TERMINATION IN DISTRIBUTED INDUSTRIAL PROCESS CONTROL SYSTEM            ABSTRACT OF THE DISCLOSURE          A control system for controlling an industrial process includes a plurality of remotely located process control units (remotes) each coupled to an associated input/ output device(s) and adapted to communicate with one another through a dual channel communications link.  Digital information in the form of data and control information blocks is transmitted between remotes with the blocks transmitted twice on each channel of the dual channel communications link.  The destination remote checks the block validity on one of the dual channels and, if valid, responds with an acknowledgement signal (ACK), and, if invalid, tests the blocks on the other, alternate channel and then responds with an acknowledgement or non-acknowledgement signal (NAK) depending on whether the data blocks tested on the alternate channel are found valid or invalid.  Each remote in the system is adapted to test the communication integrity of both channels of the communication link between it and its immediately adjacent remotes in the system and provide a line balanced termination impedance in the event one or both communication channels are degraded or interrupted.          The system thereby provides high overall operating efficiency since the remotes maintain a system-like integrity even if one of the communication links is interrupted by automatically inserting a line-matching termination impedance to prevent or minimize problems incident to unterminated,interrupted or degraded communication links, these problems including loss of signal strength in the transmission line and reflected signals.

Abstract: VIRTUAL MEMORY ADDRESS TRANSLATION MECHANISM            WITH CONTROLLED DATA PERSISTENCE                        ABSTRACT            Memory address translation and control system converts virtual memory addresses of a CPU into real memory addresses and for controlling memory functions.  Address translation function comprises converting the virtual address into an effective address using a register set addressable by a small field of the CPU generated virtual address which converts the virtual address into an expanded form; and converting the effective address into a real memory address.          The effective address is then used in the address translation step.  To enhance the translation of frequently used virtual addresses, Translation Look-Aside Buffers (TLB) contain current effective to real address translations.  The TLBs are addressed using a subset of the effective address.          The contents of the addressed TLB is examined for a match with the effective address.  When matched, successful address translation is possible and the real address stored in the TLB is available for system use.  If not matched, the page frame tables stored in main memory are accessed for the desired effective address and if found the associated real address is accessed.  Further a special data field is provided in both the TLBs and the page frame tables in main memory wherein a bit is provided for each line in the referenced page at a given effective to real address translation which bits may be used to indicate when a line of data has been accessed or altered.
