Abstract: Boom Control System Abstract Machines having a boom or arm pivotally dis-posed thereon wherein the length of the boom or arm and the angle thereof with respect to a reference plane are adjustable by means of actuators are well known.  How-ever,  it is extremely difficult,  if not impossible, to simultaneously  control  the  actuators  in a coordinated fashion to move the end of the boom or arm in a straight line path.   In order to overcome this problem,  a boom control system for a boom according to the present inven-tion controls the actuators in either of two modes of operation, the first mode of operation comprising inde-pendent control over each actuator to afford polar coor-dinate operation and the second mode of operation com-prising synchronized control over the actuators so that the end of the member may be moved in a straight line. Means are provided for manually selecting one of the two modes of operation.  Means may be provided for calculat-ing the amount of remaining horizontal throw of the boom or arm when a command to move same is issued.

Abstract: ABSTRACT OF THE DISCLOSURE           A pressure-balanced tether buoyancy system 12 useful for reducing the load imposed on a tension leg offshore platform 24 by the tethers 10 securing it to the ocean bottom. The tether 10 has tubular tether walls 11 defining a central cavity 15 isolated from the surrounding seawater.  A series of bulkheads 25 extend laterally across the interior of the tether 10, dividing it into a series of individual buoyancy cells 31.  Each bulkhead 25 is provided with a differential pressure valve 34 establishing selective fluid communication between the two buoyancy cells 31 separated by the bulkhead 25.          Preferably, each differential pressure valve 34 is adapted to open in response to a differential pressure across the bulkhead 25 exceeding the differential hydrostatic existing across the vertical distance separating adjacent bulkheads 25.          This permits a pressure gradient to be established interior to the tether 10 approximating that of the seawater in which the tether 10 is located.  A central access tube 32 can be provided interior to and extending the length of the tether 10.  The central access tube 32 can be used to pass tools through the tether 10 and to ballast and deballast individual buoyancy cells 31.

Abstract: Abstract A method and apparatus for data transfer completion notification to a processor is presented.  Input/output (I/O) devices individually or severally have associated with them command linked lists, located in system memory.  In each command linked list a processor or memory controller has placed command elements.  A subset of the command elements includes elements that are specifically to be used to report status of data transfers.   Each command element in this subset of command elements includes a pointer which points to a status entry.          Status entries, when updated by an I/O device, are placed in a status linked list also located in memory.  An I/O device may have its own status linked list or may share a single status linked list with several other devices.  Status entries contain status information on transfers between an  I/O device and memory locations.  The insertion of status entries into a status linked list is done by hardware in an indivisible series of operations.          Depending upon implementation, the hardware may then give asynchronous notification to the processor that a new element has been added to the second linked list.  This notification will cause an interrupt to the currently running process in the processor.

Abstract: SYNCHRONIZATION CIRCUITRY FOR DUPLEX       DIGITAL SPAN EQUIPMENT ABSTRACT OF THE INVENTION This circuit facilitates the synchronization of two copies of digital control units.  These digital control units control a number of digital spans.  One copy of this circuit is active at any one particular time.  This one copy drives all the remaining circuitry of the digital span interface for both copies of the digital control unit.  The other copy of this circuit is typically in the ready-standby mode.  It is not actively driving the remainder of the circuitry within its own copy.  When one copy of the digital control unit is brought on-line, a framing operation must be performed to determine the proper framing bit for both copies.  Circuitry in the cross-copy data path monitors an attempt to synchronize the two digital control unit copies. The data which is sent cross-copy is modified so that all data bits are at logic 1, except for a bit which the active copy believes is the proper S-bit or framing bit.  In this manner, the standby copy cannot reframe on any bit, except the one which the active copy believes is the proper framing and synchronization bit.

Abstract: ABSTRACT OF DISCLOSURE         The specification discloses an improved row cleaning apparatus  to  selectively  clean  away mulch  from  conservation tilled fields without cultivation of the soil.  When mounted on a tractor-drawn planter unit, the cleaning action of the present invention  improves  depth  control  and  planting  speed  of  the planter unit and facilitates seed germination while retaining the mulch  between  crop  rows  for  erosion  control  and  yield enhancement.    In  its  planter  embodiment,  the  row  cleaner disclosed herein comprises a pair of pointedly toothed wheels journaled for rotation about intersecting axes mounted on the planter unit ahead of the furrow opener.  The toothed wheels are mounted with their teeth intermeshed above the soil surface and rotate in planes symmetrically inclined downwardly,  outwardly, and forwardly of the direction of travel of the planter unit.          The toothed wheels penetrate the soil ahead of the furrow opener to a depth sufficient for the forward motion of the planter unit to  drive  the  wheels  in  rotation,  thereby  untangling  and selectively clearing mulch from the path of the planter unit, yet not so deep as to substantially cultivate or otherwise disturb the soil.   The advancing planter unit is thus presented with substantially bare, untilled soil.

Title: Electrothermal stretching mach of long steel profiles for prestressing - uses electrical heating of profiles before weld joining
IPC: E04G21/12
Filed: 1972-05-16
Abstract: This electrothermal method is used for imposing prestresses into the building components. It is used for heating a profiled component to the required temperature before it is welded to another, cool profile. The resulting stresses due to contracting on cooling of the composite welded profile introduce the required bending stresses and profile deflections. Undesirable high local stresses are avoided. The machine used for producing such preloads has supports and clamps for the components and electrical connections for heating the profiles. The apparatus has also gauges for measuring the thermal expansion in the heated components. This measuring apparatus controls the heating system so that power supply is disconnected when the required expansion has been reached. Profiles of any kind can be treated in this manner in this machine.

Abstract: The rotor's permanent magnets 3 are placed in channels between the pole shoes 2 with tangential direction of the magnetisation. The installation occurs in that the rotor without the magnets is placed inside the stator, after which the magnets one by one are axially inserted into the channels between the pole shoes and preferably in a sequence such that the radial forces partially cancel each other. The channels are open in the radial direction at least on one side of the rotor. In one version, the rotor's axle is supported in the bearings 10 on both sides of the machine, before the magnets are put into place, and there are cut-outs 7 in the machine's end shields which enable the insertion of the magnets. Disinstallation of the machine occurs in that the magnets are removed one by one before the rotor is taken out from the stator. The patent covers both possibilities: the rotor inside the stator and the rotor outside the stator. In the latter case, the word inside should be replaced with outside wherever it occurs in the explanation. <IMAGE>
