Abstract: A motor vehicle fuel system includes a tank (40), a fuel pump (44) and a carburetor (48) including a fuel inlet. A first fuel line (42) connects the pump inlet and the tank, a second fuel line (36) connects the pump outlet and the carburetor fuel inlet, and a third fuel line (50) connects the pump outlet and the tank. A first check valve (52) is disposed within the third fuel line near the tank for preventing flow from the tank into the third fuel line. The carburetor further includes a needle valve disposed within the fuel inlet. To solve an intermittent problem with the needle valve sticking in its seat, whereby the vehicle engine cannot be started, a second check valve member (54) is disposed within the fuel path upstream from the needle valve. The valve member prevents flow from the vicinity of the needle valve toward the fuel pump and the tank.

Abstract: A centering and chucking system for fixing an interchangeable element to a carrier body. The carrier body is provided with guide elements whose guide surfaces are arranged along a coordinate system through the center of which extends the reference axis, e.g. the axis of a spindle. Due to the arrangement of two centering means along one axis of the coordinate system and of at least another centering means along the other axis, the reference axes of both parts are not displaced relative to each other by changes of temperature. Although the centering means are provided outside the reference axis, the system in said reference axis is determined by them.

Abstract: A solid electrolytic capacitor has an anode body (1) and an anode wire (2) and lead out connections (8, 3). In series with the connections and the body is a fusable link (6) formed of a composite of low melting point conductive plastics metal matrix. The fusable link (6) is in the form of a pad of this material. In a preferred form this material is made by compressing into sheets metal-coated polymer particles. The sheet is cut into pads and inserted into the capacitor assemblies to act as a combined thermal and electrical fuse. Preferably the pads are less than 1mm thick and coated on both sides with solder and approximately 1mm square. The pads can be reflow soldered between the anode and the lead frame or negative wire termination. Alternatively it can be reflow soldered between the anode wire and the positive wire termination. As the current reaches high level if a fault develops in the capacitor, the metal layer will melt and also melt the plastics. The metal will then disperse in the liquid plastics and on cooling will not re-establish conduction because it is no longer in the same physical form.Alternatively the fusible link comprises metal-coated polymer particles dispersed in a resin binder and applied as a conductive paste.

A swing arm (26) is pivotally mounted to the mount upwardly and forwardly on the vehicle from the pivot axis (P) of the side stand leg. The swing arm extends to a first end (30) to receive a tension spring (32) which extends to an attachment point (22) on the leg. The first end of the swing arm is displaced from the pivot axis (14) thereof a distance greater than the distance between the pivot axis of the swing arm and the pivot axis of the side stand leg. A ground contact rubber (36) is also illustrated which may contact the ground before the bottom of the side stand leg to force the leg into the bearing support position. The overall configuration is arranged such that there is a bearing support position for the leg most forwardly relative to the vehicle, a stored position most rearwardly relative to the vehicle, and an intermediate position extending in a substan­tially downward direction. A U shaped mount (42) for the mechanism may be employed which is inverted to receive the upper portion of the side stand leg.

Abstract: A method of monitoring yarn quality in a yarn texturing process comprises measuring the velocity of the travelling yarn at two locations and comparing the measured velocities. At a first location the yarn tension is sufficient to draw out the crimp and at a second location the tension is lower such that the crimp is developed. Apparatus for performing this method comprises a measuring device (28) to measure the peripheral speed of a driving roller (26) which is part of a nip-feed device (21) serving to feed a crimped yarn (13) at the first location from a false twist device (20) to a secon heater (22) of a false twist texturing machine (10). At the second location between the second heater (22) and a third feed device (23) of the machine (10) is a second velocity measuring device (30) which comprises an inlet tube (31), an outlet tube (33) and two discs (34) of brass which form spaced measuring stations spaced by an insulating body (35). Signals proportional to the static electrical charge carried by the yarn (13) as it passes through the measuring device (30) are sent from the discs (34) to an amplifier (38) and calculating means (29), at which the speed of travel of the yarn (13) between the discs (34) is calculated.

Abstract: 2.1 During the honing of, for example, the working surfaces of pistons, the material structure is deformed in the area of the edge zone. Following the honing, the working surface is retreated in a blasting unit with a liquid jet under high pressure. The requisite blasting pressure already leads to destruction of the graphite clusters embedded in the structure, as a result of which an optimum working surface cannot be obtained in the production run. 
<??>2.2 In order to provide a surface free of metal scales, but with the graphite clusters embedded in the structure not being destroyed or dissolved away, the surface (6) is brushed in addition to the honing and high-pressure blasting treatment. To carry out this method, a tool (3a) is provided which has a tool part, such as honing sticks and/or brush sticks (15), and in addition at least one blasting device (13). A surface free of metal scales is obtained by the combined high-pressure blasting and brush treatment. 
<??>2.3 The invention ensures that the graphite clusters present in the structure remain intact. The method is simple to carry out with the tool.

Abstract: Using the circuit arrangement, the read times for a selective reading of information items transmitted over an ISDN-oriented interface (IOM) are formed for a recording device (AUE), and forwarded to the latter, from the bit clock signals (bti) present at the ISDN- oriented interface (IOM) and bit group clock signals (bgti) - which defines the boundaries of the 32-bit bit groups (BG). The read times present in the form of bit clock pulses (bti) indicate to the recording device (AUE) at what times the information items are to be read and subsequently to be stored. The circuit arrangement contains a shift register (SR) which is formed by a number of registers corresponding to the number of bits of a bit group (BG), a reset device which is implemented, for example, by means of an inverting element (INV) and a switching means (SI), a logical AND gate (UV) and several switching means (S1...S16), the setting of which determines which information items or, respectively, bits of a bit group (BG) are to be read and stored.
