Abstract: An electron beam is accelerated in an electron accumulating ring which consists of a magnet for deflecting an electron beam, a magnet for converging the electron beam, a high-frequency acceleration cavity for accelerating electrons, and a vacuum chamber, by superposing a voltage component that changes with the passage of time, e.g. in the form of a sine wave on the power source of the converging magnet to change the intensity of the converging magnet. Thus, the number of electron vibrations in a betatron can be changed for each passage of electrons through the converging magnet, and the degree of attenuation becomes greater than the degree of instability of the beam, so that the electron beam is prevented from becoming unstable.

Abstract: A dispenser for capsules or the like utilizes a turnstile member (44) rotatable in only a single direction to transport the capsules from a reservoir (14) to an exit port (40). Fingers (50) on the turnstile arms interleave with corresponding fingers (52) on the dispenser housing (38) to prevent a capsule from being rotated beyond the exit port and back into the housing. A propeller member (20) in the reservoir orients the capsules in a predetermined orientation before they are fed into the turnstile member. A cap (16) on the exterior of the housing which rotates the turnstile member utilizes a bayonet-type detent mechanism (68) to bias the cap (16) into successive dispensing posi­tions. The cap (16) must be pushed toward the housing (38) to be rotatable to the next dispensing position.

Abstract: The insert (10) is provided with at least one annular groove (16) in its outer periphery and with chamfered ends (14) for entry of the insert into a hole (30) in plastics parent material (32) with an interference fit so that the plastics material of the hole wall is temporarily displaced and then resiles into the groove (16) to retain the insert in position in the hole. Opposed shoulders (18, 20) of the groove (16) are sharp edged to shear or dig into the hole wall to also resist axial movement of the insert in the hole (30). The insert is primarily intended as an anti-creep spacer to take the compressive load of a bolt or like mounting of the component and so avoid or minimise such load on the plastics material which would otherwise cause creep of the latter and loosening of the mounting.

Abstract: The invention relates to a method of testing assemblies, which can be described by first order differential equations. The intrinsic assembly parameters are derived by direct measurement of the output variables of the assembly, being evaluated in a filter unit (1). In the method according to the invention, the evaluation is carried out in a digital filter unit (1) which consists of a plurality of FIR filters of a first type (3, 5) and of a second type (6). Their weighting factors (hi, gi) are freely preset as integers and namely in a desired form which can easily be produced and processed. In the region of the assembly excitation frequency, an error resulting from the free preset is overcome by means of a simple correction factor. The method can be used advantageously in selective protection technology for distance and fault location measurement. <IMAGE>

Abstract: Les types antérieurs de convertisseurs AC/CC régulés n'assurent qu'une régulation unidirectionnelle et/ou effectuent la régulation sur le côté primaire d'un transformateur principal utilisé dans le convertisseur. Il en résulte un convertisseur quidoit être capable de fournir une amplitude de tension de régulation relativement importante et/ou un convertisseur qui doit utiliser des dispositifs de commutation à haute tension dans le circuit primaire. Afin d'éviter ces problèmes, on prévoit un convertisseur AC/CC régulé qui comprend un transformateur (22) ayant un enroulement primaire (24) qui reçoit la puissance d'entrée AC et un enroulement secondaire (28), un organe (30) couplé à l'enroulement secondaire et destiné à redresser la puissance de sortie de ce même enroulement, un circuit de commutation (38) couplé à l'organe redresseur et destiné à développer une tension de compensation qui se combine avec la puissance de sortie redressée de l'enroulement secondaire afin de développer la puissance de sortie à CC régulée par tension et un organe servant à commander le circuit de commutation (46), ce qui permet à ce circuit de développer une tension de compensation en aide à la puissance de sortie redressée de l'enroulement secondaire lorsque cette puissance est inférieure à un niveau désiré et qui s'oppose à la puissance de sortie redressée de l'enroulement secondaire lorsque cette puissance est restée supérieure au niveau désiré.

Title: Inert gas welding torch.
Inventor: KLEPPEN ARTHUR LEONARD JR
IPC: B23K9/28
Filed: 1988-08-02
Abstract: The present invention is a tungsten inert gas or similar welding torch which is readily adjustable in length for different welding situations. The torch has a relatively conventional head with a heat shield attached at the lower end. The heat shield serves as a resilient telescopic mounting for the gas cup which surrounds the electrode. It further serves to give thermal and mechanical isolation between the torch head and gas cup. A gas diffusion screen pack is located within and bears against an inner circumference of the gas cup to provide resilient support and center the cup about the longitudinal axis of the electrode. The gas cup may be extended or retracted a limited distance within the heat shield and may also be rotated if desired. Alternatively, longer or shorter electrode collet bodies can be screwed into the head to provide almost unlimited adjustment of torch length. A gas cup of appropriate length is used with each collet body.
