Patent SE-7404816-L (SE)
IPC: B28B1/52
Filed: 1974-04-09
Abstract: A method of manufacturing a contact body for at least one flowing medium is disclosed wherein layers of asbestos fibers are formed and arranged so that the layers bear against one another at mutually spaced positions to provide channels in the body extending from one end thereof to the other to allow the flowing medium to pass therethrough. The layers of the contact body are first treated by supplying to the layers at least one inorganic substance which produces a hydrated precipitate on the asbestos fibers of the layers. Thereafter the layers are heated to a temperature which is at least within a temperature range at which the hydrated precipitate releases its water of crystallization, but which temperature is below the sintering temperature for the substances remaining in the body. As a further step, at least one further substance is supplied to the contact body layers which restores the mechanical strength of the body lost by the transformation of the asbestos fibers during the heating step.

Abstract: Absorptive substrates, such as asbestos cement, concrete plaster work, can be impregnated to lock the pores and to consolidate the substrate, especially old and weathered plaster work, with aqueous plastics dispersions, if dispersions are used which have an average particle size of about 0.02 to at most 0.1 mu m, and preferably from 0.036 to 0.080 mu m. As opposed to conventional dispersions with larger particle sizes, the penetration of dispersions according to the invention reaches the same values as that of the solvent-based impregnating and priming compositions hitherto used. Aqueous dispersions are easier to handle and permit relatively high solids contents at a moderate viscosity.

Abstract: Thyristors are substituted for conventional diodes in the rotating rectifier assembly of a brushless exciter in a synchronous dynamoelectric machine. In contrast with prior systems in which thyristors are switched at relatively high ceiling voltages (requiring thyristors of high power rating and additional components for fast de-excitation), the gates of the thyristors in the present invention are fired only at a low voltage point of the negative half cycle of the polyphase armature voltage waveforms for fast de-excitation and are maintained in a fully conducting condition during the positive half cycle. This permits the use of thyristors having a relatively lower power rating and makes unnecessary additional components to achieve fast de-excitation.

Abstract: A preassembled bolt and washer-like device designed for use in securing an upper, plastic-like workpiece to a lower support structure so that cold flow of the plastic is minimized while applying a relatively high clamp load to the joint. The washer includes a tubular sleeve having radially inwardly directed protuberances at the upper region of the inner wall designed to snap onto the shank of the bolt and be axially retained and free spinning therein. The upper extremity of the shank of the bolt includes a radial outward protuberance cooperating with the protuberance on the sleeve. The threaded region of the shank extends within the confines of the sleeve so the thread runout at the upper extremity of the shank will not prevent the sleeve from clampingly engaging the lower support structure.

Abstract: A wheel brake cylinder (9) includes a piston (4) guided on a pin (3). To compensate for friction lining wear a friction ring (2) is arranged on the pin (3) and held captive in a recess (1) of the piston (4). The piston (4) is able to move relative to the ring (3) by an amount (L) equal to the desired brake play. When the brake play exceeds the distance L, actuation of the piston (4) causes the friction ring (2) to be moved along the pin (3) in order to reduce the brake play to distance L. The friction ring (2) is a slotted plastically-deformable ring which initially has an external diameter sufficiently small to allow it to be arranged in the recess (1). The ring is expanded by temporary insertion of a fitting pin (not shown) into it so that the ring is held captive in the recess (1). Finally, the piston, with ring inserted, is pushed on to pin 3, so that the ring is held frictionally thereon. <IMAGE>

Abstract: A static instantaneous overcurrent relay with reduced transient overreach is provided for use in protecting an a-c power line from overcurrents. The relay operates on an input signal representative of the magnitude of the current in the a-c power line and develops a relay output signal when the magnitude of the current reaches a predetermined magnitude. In a preferred embodiment, the relay includes a level detector circuit for receiving the input signal which is in the form of a pulsating waveform having the same frequency as the a-c power line. The level detector circuit develops a discrete level detector output signal in response to each pulse of the waveform which attains a magnitude representative of the predetermined magnitude. Output circuit means is coupled to receive the discrete level detector output signals and includes temporary inhibit means for inhibiting the development of the relay output signal until the output circuit has received two of the discrete level detector signals. In one form of the invention, the temporary inhibit means includes delay circuit means for receiving the discrete level detector output signals and developing a delayed signal. AND circuit means is then provided to receive the discrete level detector output signals and the delayed signal, resulting in a relay output signal after two level detector output signals are present. In one form of the present invention, the relay has a transient overreach percentage of less than 8% for power line angles up to 75 DEG . The relay of the present invention may be employed in connection with a single phase input signal as well as with a three phase input signal.

Abstract: The invention is directed to a container for receiving and safely storing radioactive or other materials damaging to living organisms, especially such materials as vitrified radioactive fission products or irradiated nuclear reactor fuel elements. The container includes a vessel and a sealing cover. The vessel has a circular opening at one of its ends for receiving the materials to be stored therein, and a sealing cover is seated in this opening to tightly seal the container. In order to obtain a container of the kind which has the required high impermeability to gas, the open end of the inner bore of the vessel is widened to define a conical surface. A sealing cover is pressed into the vessel at this conical surfce. The sealing cover has a peripheral surface which converges toward the interior of the vessel and which has a taper corresponding to that of the conical surface of the vessel. The vessel wall and sealing cover are welded together by means of a fused-mass joint extending around the entire periphery of the cover. By means of the conical configuration of the upper end portion of the vessel and of the sealing cover, a considerably improved seal between the vessel wall and the sealing cover is obtained. A method for sealing the container is also disclosed.
