Abstract: TIRE CURING METHOD                         Abstract A method is disclosed for curing a green rubber tire having a closed interior cavity with two spaced ports extending from the interior cavity to the tire exterior.  The method includes the step of posi-tioning the tire within a pressure vessel.  The pres-sure vessel and the interior cavity and porous core are then filled with a liquid at an elevated temperature which is sufficient to cure the rubber.  The liquid is then circulated at the elevated temperature through the pressure vessel around the exterior of the tire and through the interior cavity of the tire.

Abstract: Abstract The present invention relates to a method of filling fluidiz-able material in flexible containers. This implies that im-mediately after the filling operation the container filled with fluidizable material will not be stable. In order to obtain a simple and safe filling operation and at the same time simplify the further transport of the filled container, the bottom plane (6) during the filling operation itself and immediately afterwards is adjusted to an angle (y) of at least 2° with the horizontal plane and a support means (4) is adjusted to an angle of at least 2° with the vertical plane such that the container (1) leans back against the support means when it is filled with fluidizable material and does not slide off the bottom plane (6) even when its lifting loops are released from the holding device. The bottom plane and the support means can comprise a unit in which the bottom plane forms about 90° with the rear wall (S) of the support means 4. The angles x and y can be equal or different and preferred values for these angles are 5-15°.

Abstract: ABSTRACT    A  bus for  coupling a plurality  of units  in a data processing   system  for   the  transfer   of  information therebetween.   The  units  are   coupled  in  a  priority arrangement   which   is  distributed   thereby  providing priority  logic  in each  of  the units  and  allowing bus transfer cycles to be generated in an asynchronous manner.    Priority  is  normally granted  on  the basis  of physical position on  the bus, highest priority  being given to the first unit on  the bus and lowest priority  being given to the  last unit  on the  bus.  Each  of the  units includes priority   logic   which  includes   logic   elements  for requesting a  bus cycle, such request  being granted if no other higher priority unit has also requested a bus cycle.          The request for and an indication  of the grant of the bus cycle  are  stored in  each unit  so requesting  and being granted  the bus  cycle respectively,  only one  such unit being capable  of having the  grant of a bus  cycle at any given time, whereas any number  of such units may have its request pending at any particular time.  A modification to the  priority logic allows a  lowest priority  unit to be physically positioned at other than the last unit position on the common bus.

Abstract: HYBRID LINEAR ACTUATOR                        ABSTRACT   A linear actuator is a hybrid in that movement of the armature is influenced by the field of permanent magnets and the field of a coil when it is energized by direct cur-rent.  The coil is fixed in a ferromagnetic shell and a pair of permanent magnets are fixed in the shell axially of the coil.  The armature has a reduced diameter tip or end which is influenced by the magnets when the coil is deenergized and which enables the force on the armature to remain generally uniform over the working stroke of the armature.  The linear actuator is shown operating a sleeve valve spring biased to closed position and opened relative to the metering cone by application of direct current to the coil.  The effective magnitude of the current determines how much the valve opens.

Abstract: ABSTRACT OF THE DISCLOSURE         This invention relates to an improved attach-ment for a propane/butane fuel container of the aerosol type to provide torches, burners, heaters, lanterns, and the like.  In one embodiment the attachment itself includes a torch and control valve, while in other embodiments it is an adaptor to connect conventional or separate devices to the container.  The attachment has a cylindrical boss with a central well which screws onto the threaded stem portion of the fuel container to an assembled position in which an actuator pin opens a self-sealing outlet valve in the container.  The attachment has a first O-ring seal seated inside the well and a second O-ring seal seated around the inlet bass just below an outwardly extending-shoulder.  As the assembly is tightened into position on the fuel container, these two O-ring seals are simultaneously compressed, the first against the upper surface of the stem portion and the second against the annular rim of the container.  This has the advantage of automatically providing a  double seal against leakage of the fuel, as well as transferring some of the structural stress from the stem portion of the container to the stronger annular rim.

Abstract: ASYNCHRONOUS BUFFERED COMMUNICATIONS INTERFACE               ABSTRACT A communications interface for controlling asynchronous data transmission between a host computer and an input/output device achieves very high data transfer rates and reduces I/O bottlenecks.  The inter-face includes a microprocessor and a memory addressable thereby.  The microprocessor controls data transfer from the host computer into an output buffer maintained within the memory and controls subsequent data transfer from the output buffer to an output device, indepen-dently of the operation of the host computer.  Data received from the host computer is stored directly into the appropriate output buffer storage location without any time-consuming reading and writing of the data by the microprocessor.  This is accomplished by providing a hardware register for storing data received from the host computer.  At the appropriate time data transfer from the microprocessor to the memory is disabled, and data transfer from the register to the memory is enabled.  Data is thus rapidly transferred from the register directly into the memory location addressed by the microprocessor.
