Abstract: The copper wires employed for electrical resistance seam welding of tinned sheet metal with the help of wire electrodes until now had to be taken back to the smelter as old metal after a few applications. The additional operating costs associated with this were until now unavoidable for long seam resistance welding of tinned sheet metal since multiple uses or applications of the copper wire for resistance seam welding have proven to be impossible in spite of years of research. The problem of these additional operating costs can be solved such that new copper wires with a reduced diameter can be directly drawn from the copper wire employed as wire electrodes for resistance seam welding after their use in welding. These wires then, for example, can be used as signal conductors or as windings. The properties of these wires are totally in accord with copper wires that are directly drawn from new copper. By this process, the additional operating costs mentioned above are substantially reduced and in many cases are even totally eliminated.

Abstract: An indirect extrusion process, and apparatus therefor, for producing an extrusion product from a hot metal billet. A press container is mounted to be substantially axially stationary during extrusion of a billet. A hot billet, a die and a pressure disc are located into the axial throughbore of the container so that the billet is sandwiched between the die and pressure disc, with the pressure disc having a maximum outer diameter between opposite radial faces which is slightly less than the diameter of the axial throughbore to define a diametrical clearance between the pressure disc and the press container. A bolster is located adjacent the pressure disc and is axially fixed to substantially prevent axial movement of the pressure disc in a direction toward the bolster during extrusion. The bolster exerts a relatively insigificant axial force against the container. An elongated stem having an axial passage is moved into the throughbore of the container to press the die toward the bolster, causing the billet to be extruded through the die to create an extrusion product which exits the container through the axial passage in the stem, while extrusion of the billet through the diametrical clearance between the pressure disc and the container is substantially avoided.

Abstract: An auxiliary fuel supply system is provided for a two cycle internal combustion engine (302). A first fuel line (350) supplies fuel from the fuel pump (338) to a solenoid (352) which is continuously cyclable between ON and OFF states during running of the engine, includig high speed operation where detonation may occur. Fuel then flows through a second fuel line (354) to a restriction orifice metering housing (356), and then to a plurality of third branch fuel lines (358, 384, 386, 388, 390 and 392) for delivery to respective cylinders. The restriction orifices provide a pressure drop from the second fuel line to the plurality of third fuel lines, to provide lower fuel pressure in the third fuel lines, to reduce the chance of leakage at the intake manifold (326), and also to reduce fuel pressure fluctuations in the third fuel lines otherwise due to cycling of the solenoid. Metering housing structure is disclosed. The solenoid is controlled by a variable duty cycle oscillator (408), which in turn is controlled by a fuel enrichment signal (84) output by an electronic control which is responsive to engine knock and/or temperature. Control circuitry is disclosed.

Abstract: An encoder applies a digital filterbank such as a transform or subband filterbank to an input signal to generate frequency subband information, encodes the resultant subband information using adaptive bit allocation to generate fixed-length values represented by fixed numbers of bits and variable-length values represented by variable numbers of bits, and formats the subband information into an encoded signal in which the fixed-length values are assembled into preestablished positions within the encoded signal. In response to an encoded signal including subband information represented by fixed-length values and variable-length values, a decoder extracts fixed-length values represented by fixed numbers of bits from preestablished positions within the encoded signal, extracts variable-length values represented by variable numbers of bits, wherein the variable numbers of bits are established in response to fixed-length values, and generates an output signal by applying an inverse filterbank to the extracted subband information. <IMAGE>
Patent BR-9106251-A (BR)
Inventor: ROGERS BOBBY E
IPC: A61M39/02
Filed: 1991-04-09
Abstract: A medical valve assembly is described in which the valve assembly has a female luer lock portion on an inlet end of the device and a male luer lock portion on the outlet portion of the valve. A movable piston seals the inlet portion of the valve from the outlet portion when the piston is in the closed position. When a syringe is attached to the inlet portion of the valve assembly, the piston is displaced in a manner that unseals a fluid channel inlet. This connects the end of the syringe to the fluid channel which is connected, at its outlet end, to a catheter or other device, connected to a patient. Thus, medication can be introduced to, or fluids aspirated from, a patient's bloodstream, without the use of a syringe having a needle. When the syringe is removed from the inlet to the valve assembly, the piston is urged by a biasing means into its original closed position creating a seal between the inlet portion of the valve and the outlet portion of the valve. This feature maintains catheter patency. The top surface of the piston along with the area of the female luer lock connector does not have any fluid reservoir and can be easily cleaned to prevent the possibility of bacterial infection as a result of repeated uses of the valve assembly.

Abstract: The multilevel convertor includes capacitors (C1,C2...,Cn) for each of its cells. The capacitors have nominally charge voltages proportional to their row in the convertor. The convertor also includes control devices (BT, DA1...,DAn, pe2...,pen) designed to evaluate the voltage source (VECn) of the convertor. As soon as the voltage source (VECn) of the convertor is less than a set value, to suspend the nominal function of the convertor (sd) and to operate switches (T1,T`1,T2,T`2...,Tn,T`n) so that when the voltage (VE) of the voltage source (SE) has a value between zero and a least high nominal charge voltage, it charges all the capacitors of the convertor. When the voltage of the voltage source exceeds the least high nominal charge voltage, the capacitor (C1), nominally charged by this last voltage, is switched out of circuit. The voltage of the voltage source continues to charge the capacitors (C2...,Cn) demanding higher nominal charge voltages until the voltage exceeds that next least high voltage (C2), capacitor (C2) is then switched out, this continues until all the capacitors are charged to their nominal charge voltages. At the end of the complete charging sequence the control device restores the nominal operation of the convertor.
