Patent EP-0414332-A1 (EP)
Inventor: DAUTZENBERG NORBERT DR-ING
IPC: B22F7/06
Filed: 1990-08-16
Abstract: The invention relates to a process for preparing blocks or profiles by extruding heated preforms consisting of at least one steel powder which is produced by water atomisation of a steel melt, subjected to a reductive annealing and then compacted to give disc-shaped compacts with a density of at least 6 g/cm<3>, the preforms being formed by placing the compacts, corresponding in their disc shape to the cross-sectional shape of the preform, in layers in a sheet-metal capsule up to a desired height, by then closing and evacuating the sheet-metal capsule and, if required, machining away from the block or profile the sheath formed by the stretched sheet-metal capsule after extrusion. In order to indicate a process which permits the production of steel blocks and profiles which are plated with a material of a different type on the inner surface (in the case of hollow profiles) and/or the outer surface or on parts of these surfaces, while guaranteeing material properties which in many cases can only be achieved by powder metallurgical processes, i.e. in particular a segregation-free fine-grained structure in the extruded block or profile should be ensured, it is proposed to use compacts which, in the regions corresponding to the desired plating zone, are formed of the plating material. <IMAGE>

Abstract: The two rotary parts (10,11) of a clutch are connected through a coil spring (14) having a clamping portion (B) winding round a shaft member (12) of one of said parts to clamp onto that part. A non-clamping portion (A) of the spring extends from the clamping portion and is held by the other of the rotary parts in such a manner that the torque on the non-clamping portion (A) rises, according to the spring characteristic, when there is relative rotation between the parts to bring a release member towards the clamping portion. When the release member engages the clamping portion (B), the grip of that portion on its rotary part is loosened but the torque on the non-clamping portion (A) rises further while the clamping force on the clamping portion (B) is greater than the torque on the non-clamping portion (A). Once both are balanced the clamping portion (B) slips on the shaft member (12), and the torque is held at its limit value after then.

Abstract: The invention relates to a device responsive to impacts and overturning, placed on the "floor" of a vehicle, and capable of triggering a signal on the basis of a sudden deceleration or an overturning. This device consists of a truncated-conical casing (1) with vertical axis and closed at the top and in which a sphere (4), whose weight is sufficient to keep the lever (6) of the microcontact (5) in the bottom position by way of the spring (7), can dance freely. The movement of the sphere (4) caused by an impact takes place vertically by reaction on the conical wall, thus freeing the microcontact. In the case of overturning, the sphere moves under gravity, thus freeing the microcontact. This device according to the invention is particularly intended for any transport vehicle, and enables signals of any kind to be automatically triggered in the event of an accident. <IMAGE>

Abstract: A front leg (1) is formed of a linear support pole rising upright from a stationary stud (8) and a rear leg (2) is formed of a lower support pole (2a) extending along a diagonal line connecting the upper end portion of the front leg and the lower end portion of the rear leg and an upper support pole (2b) extending from the upper part of the lower support pole (2a) and arching upwardly and rearwardly. Further, an energy absorbing member (12) is bridged as a diagonal member between the upper end of the front leg and the lower end of the rear leg to constitute the leg structure. This leg structure serves to absorb impact energy by anti-plastic deformation force that occurs when the rear leg (2) and the member (12) receive impact beyond a predetermined value and undergo plastic deformation, and supports the seat in a support posture at the time of normal use. This leg structure can be utilized as the leg structure of seats to be fitted not only in airplanes but also in automobiles, railway vehicles, and so forth.

Abstract: An adsorbable gas can be efficiently recovered by subjecting a gas containing the above gas at a low concentration to adsorption/desorption treatment in a first adsorption column packed with an adsorbent, and condensing a desorption gas, containing the adsorbable gas at a higher concentration, discharged from the column. In this process a desorption gas discharged from a second adsorption column is introduced into the first column wherein the adsorption has been completed to adsorb and desorb an adsorbable gas contained in the desorption gas and a gas discharged in the step of condensing the desorption gas and containing a non-condensed adsorbable gas is introduced into the second column to adsorb an adsorbable gas contained in the discharged gas, the adsorbed adsorbable gas being desorbed in the second column in the next adsorption/desorption cycle to give a desorption gas containing the desorbed adsorbable gas, which is discharged from the second column and introduced into the first column where in the adsorption has been completed. This process is easy to operate and requires little thermal energy for desorption.
