Abstract: CU????EY-1 SYNCHRONOUS/ASYNCHRONOUS DATA COMMUNICATION ARRANGEMENT      Abstract of the Disclosure A data communication arrangement is disclosed for multiplexing an asynchronous binary data signal with a synchronous binary data signal by the timely insertion of an extra data bit in selected synchronous data words and by delaying the transmission of the resulting multiplexed data words.  The extra data bit is generated when a binary level transition occurs in the asynchronous binary data signal. The transmission of the multiplexed data word is delayed a fixed amount of time relative to the binary level transition of the asynchronous signal to preserve the timing between transitions in the asynchronous signal.  The received multiplexed data words are demultiplexed into a synchronous and asynchronous binary data signals.  The demultiplexed asynchronous binary data signal emerges having transition timing which is the same as the transition timing of the original asynchronous binary data signal.

Abstract: ABSTRACT     The invention concerns a heating boiler operating on solid, comparatively finely divided fuel, such as chips or peat, and which is used to produce hot water or steam. The boiler comprises a furnace, in which the grate consists of a shell-like burning basket, which can be placed in rotary motion about its substantially horizontal axis. The rotating of the burn-ing basket may be arranged by connecting to the basket a tubular arm pro-vided with a gear wheel and which is connected to a motor placed outside the boiler. The arm then simultaneously serves as duct through which the fuel is introduced into the burning basket. The purpose of the rotating burning basket is to boost the combustion reaction so that comparatively wet fuel can be used in the boiler. The combustion may furthermore be boosted by placing the burning basket in the furnace in a housing having as its extension a cyclone constituting a helical exhaust duct for the flue gases, which sets the gases at high temperature into strongly turbu-lent motion.

Abstract: ABSTRACT OF THE DISCLOSURE          A threaded pin has flutes along the threads formed by roll-forming threads over a preformed section having either flat sides or dished sides.  The major diameter of the threads lies along ridge crests bordering the flutes, and the minor diameter of the threads lies at the base of the flutes.  The threads extend along the major diameter in each of the ridge crests for a distance on an order of magnitude of the distance across the mouth of each flute.  The preformed section is formed by extrusion.  The flutes provide space for material from a threaded collar forced into them to provide a thread lock.  The circumferential extent of each ridge crest at the major diameter of the threads is of the order of the extent of the flutes at the major diameter of the threads.  Thus, the distance across the mouths of the flutes is about the same as the distance along the major diameter of the thread on the ridge crest flanking each flute.  The major diameter of the thread is the maximum diameter of the thread and this diameter is maximized in the ridge crest to maximize the area of the threads that resists axial tensile forces.  The flutes are concave outward to provide a steep slope to the flutes, so that the material displaced therein provides high resistance to turning.

Abstract: Improved Gear Pump or Motor With Low Pressure Bearing Lubrication Abstract An improved gear pump or motor includes seal plates (30, 32) having a lubrication channel (48, 50) communicating between the shaft bearings (18, 20, 22, 24) and the low pressure side of the zone (62) where the gear teeth (58, 60) intermesh.  Lubricant flow is directed first through one bearing on one side of the pump and then back through a separate channel (54, 56) to the other bearing on the same side of the pump.  Placement of the lubrication channels on the low pressure side of the pump where the volume between intermeshing teeth is increasing and the pressure between the teeth is below inlet pressure ensures that flow reversals in the bearings and lubricant aeration are avoided; and renders bearing flow rate less sensitive to pressure, so that relatively large flow channels may be used in the wear plate.
