Abstract: Cylinder liners of internal combustion engines must be adequately cooled to obviate oil degradation, carbon packing in the ring area, and piston seizure. The engine includes a block which cooperates with the cylinder liners to define an upper and lower axially spaced coolant chambers. A sleeve is located in a groove defined in the cylinder liner and disposed between the upper and lower coolant chambers. The sleeve and the cylinder liner define a plurality of circumferentially spaced venturi throats. The venturi throats provide a relative long flow path and controls the flow rate of the coolant being communicated from the lower coolant chamber to the upper coolant chamber in order to dissipate heat away from the cylinder liner.

Abstract: A signalling system adapted for digital signals includes a signal transmitter, a signal receiver and a connection which connects the transmitter to the receiver. The transmitter includes an output buffer which has at least one transistor connected to the lowest level of a signal supply voltage, such as to "0" potential or earth potential. Driving or steering of the transistor in response to a received control signal causes the transistor to switch from a state of high impedance to a state of low impedance which exhibits resistive or at least predominantly resistive properties, such as to form an information-carrying output signal. A first of two series-connected transistors is connected to the lowest level of the signal supply voltage, for instance "0" or earth potential, and the other transistor is connected to the signal supply voltage. A connection conductor on which the information-carrying signal is transmitted is connected between the transistors. The transistors are brought to different states simultaneously, and in a state of low-impedance, the impedance value corresponds to the impedance value (the resistance value) of the connection.

Abstract: A method is provided for preparing a cladding tube having an outer substrate, an intermediate zirconium barrier layer, and an inner liner. The method includes the following steps: (a) bonding an inner liner alloy sheath exterior circumferential surface to a zirconium sheath interior circumferential surface to form a barrier/inner liner sheath, and (b) bonding the exterior surface of the zirconium sheath on the barrier/inner liner sheath to the interior circumferential surface of an outer substrate alloy tube to form the cladding tube. Alternatively, the method includes the following steps: (a) bonding the zirconium sheath exterior circumferential surface to the outer substrate alloy tube interior circumferential surface to form a substrate tube/barrier sheath, and (b) bonding the exterior circumferential surface of the inner liner alloy sheath to the interior circumferential surface of the zirconium sheath of the substrate tube/barrier sheath to form said cladding tube. In either approach the tube produced by step (a) is heat treated before step (b) is performed. The bonding steps are performed by extrusion and sometimes hot isostatic pressing.

Each time a true cause is found, the data on the degree of relevance of the cause is so corrected that the degree of the other causes becomes high and those of the other causes become low. On the basis of the data on the failure rate and the data on the degree of the relevance, the certainty of each cause is inferred by a first inferring means. The data on the predicted failure rate of each cause and the data on the actual failure rate are compared, and the certainty of each cause is inferred by a second inferring means in such a way that the certainty of a cause having less errors becomes higher. The certainties inferred by the first and second inferring means are weighted in a predetermined way. Based upon these weighted certainties, final certainties are inferred.

Abstract: A method for forming a sintered hard metal composite is provided in which unsintered nodules of a pre-blended hard metal powder of a first grade are uniformly dispersed into unsintered nodules of a pre-blended hard metal composite of a second grade. The pre-blended hard metal powders form a composite powder blend which is subsequently pressed and sintered to form the dispersion alloyed hard metal composite. A sufficient amount of pressing lubricant is provided to one of the pre-blended hard metal powders so that each of the hard metal powders shrinks at approximately the same rate relative to the application of pressure during the compacting process. The pressing lubricant is added to that hard metal powder which shrinks more during sintering. By providing uniform shrinkage of the constituent powder grades, migration of the binder from one constituent grade to the other constituent grade is minimized, thereby allowing the composite powder blend to achieve superior properties because each of the constituent grades maintains its own integrity. In addition, the uniform shrinkage of the constituent powders prevents irregular surface conditions of the "as sintered" surface.

Abstract: An arrangement for controlling and adjusting the output power of radio frequency signals sent from a radio unit (100) and the input power of radio frequency signals received by the radio unit. Variations in the amplification/attenuation of transmitter-and-receiver units are simultaneously compensated for in both the transmitter part and the receiver part of the units so that the amplification will remain the same irrespective of these variations in operation. A detector signal (Udet) is compared with a reference signal (Uref) by a difference amplifier (112), which generates a difference signal (Ue). The detector signal (Udet) is measured by a power sensing means provided in the vicinity of an antenna (113), and corresponds to the power at which radio frequency signals are transmitted. The reference signal (Uref) corresponds to a desired power of transmitted radio frequency signals. The difference signal (Ue) generated by the difference amplifier (112) controls the setting of the amplification of a first variable amplifier (109) and a second variable amplifier (110), adapted to amplify radio frequency signals that are transmitted and received respectively.

Abstract: A carburetor having a fuel pump, a fuel metering diaphragm defining a fuel chamber on one side of the diaphragm and an air chamber on the opposite side of the diaphragm vented to the atmosphere, and a second diaphragm defining a first chamber on one side of the second diaphragm in communication with the carburetor fuel pump and a valve actuated by the second diaphragm to control the application of engine crankcase pressure pulses to the fuel metering diaphragm in response to the pressure at the carburetor fuel pump. The second diaphragm is yieldably biased to position the valve in a first position and upon cranking for initially starting the engine, pressure pulses from the engine crankcase are communicated to the air chamber of the fuel metering diaphragm. The pressure pulses from the engine crankcase act on the fuel metering diaphragm causing it to fluctuate and thereby increase the quantity of fuel mixed with the air flowing through the carburetor to facilitate staring the engine. After the engine is started and is running, the carburetor fuel pump output pressure increases and acts on the second diaphragm from within the first chamber to displace it and move the valve to its second position to prevent the pressure pulses from the engine crankcase from materially affecting the fuel metering diaphragm to permit conventional operation of the carburetor.
