Abstract: An actuator for a spring brake used for parking and emergency has a spring operating on the brake push rod which will apply braking unless fluid pressure in the braking system applied to a piston overcomes spring pressure. To disable the spring brake the rod is retracted by a mechanism coupling the piston to the rod so that the brake is automatically restored into service when the piston is operated by the fluid pressure. The mechanism has a one-way clutch engaging a threaded push rod by means of a nut in non-self-locking engagement on the push rod threads.

Abstract: Arranged within a frame construction formed by horizontal upper bars (3) and vertical side bars is a refractory wall with a cavity (2) for accommodating a bath. The lateral areas of the frame construction are closed off by means of screening plates (5) and the upper side of the wall is closed off by means of a cover plate with a central opening. A hood (7) is placed on the upper part of the frame construction. The hood opens into an extraction duct (8) and, at its front side, has a window (9) which can be moved up and down. The upper bars (3) are hollow and each upper bar located in the vicinity of the window has a number of holes (12) in its upper side. Air or gas is passed into the interior of the upper bars via a pipe (10), and the air or gas emerging from the holes (12) forms a protective air or gas curtain when the window is open. This design renders unnecessary any additional pipes for the supply of air or gas and, as a result, access to the duct is unhindered. <IMAGE>

Filed: 1978-02-27
Abstract: This machine element, e.g. a drill bush (121), has a hardened main body (180) made of steel and an approximately 0.1 mm-thick lining (189). The lining (189) is composed of hard particles, such as tungsten carbide particles, which are distributed in a softer matrix, in particular chromium nickel, and bonded to the main body by the latter. The lining (189) is compact or has interspaces for lubricant between the tungsten carbide particles. A base coating of wet binder, which contains chromium nickel powder, and tungsten carbide particles is first of all dried onto the main body (180), the tungsten carbide particles in the wet binder being compacted by rotation or vibration of the workpiece. Binder and a measured quantity of chromium nickel powder are then applied and all the chromium nickel powder is melted at 1050-1110 DEG C with the workpiece rotating or vibrating. In the case of bushes with a small inside diameter, the longitudinal opening (181) of the main body is filled with lining composition and the opening (187) then pierced, by means of an electrode (188) for example. It is advantageous that the wear resistance of the lining corresponds to that of solid tungsten carbide whereas the coefficient of expansion of the machine element itself corresponds to that of steel.   <IMAGE>

Abstract: Sintered glass-ceramic substrates containing multi-level, interconnected thick-film circuit patterns of highly conductive metals such as gold, silver or copper are provided which can be fired in air (for gold and silver) or in neutral atmospheres (for copper) at temperatures below the melting points of these metals. This has been made possible by the discovery that finely divided powders of certain glasses described herein sinter to essentially zero porosity at temperatures below 1000 DEG  C. while simultaneously maturing to glass-ceramics of low dielectric constant, high flexural strength and low thermal expansivity.

Abstract: HIGH VOLTAGE SEMICONDUCTOR DEVICE HAVING IMPROVEMENTS TO THE dv/dt CAPABILITY AND PLASMA SPREADING A semiconductor device used for high voltage applications exhibits reduced susceptibility to being inadvertently turned on by capacitive charging currents generated by relatively high voltage transients impressed across an anode and a cathode of the device. The capacitive charging currents are manifested as gate currents which in a thyristor render the device conductive it they exceed a critical valve, and in a transistor are multiplied by the current gain. A capacitor integral with the semiconductor device structure is coupled to a gate region of the device to divert a portion of transient-generated capacitive charging currents, thereby reducing the associated gate currents and improving the dv/dt capability of the device.

Abstract: Two-way time division multiplex (TDM) links interlace a plurality of digital exchanges such that the possibility of path selection is available for transferring information between two of the exchanges. Instead of conventionally selecting a path for each ordered call set up, the exchanges coact such that there is generally established a one-way TDM loop between all exchanges, this loop being established by parts of said links. For calls between arbitrary exchanges the loop only is used. The operational ability of the links is monitored continuously before and after establishment of the loop. It is possible to reconfigurate the loop during calls in progress for achieving improved information transfer quality.
