Date Jun. 2, 1988.An HF communications system comprising a plurality of radio stations, each radio station including a transceiver and a control means therefor, the control means including a processor and a memory, the memory storing a model of the ionosphere of a designated region in digital form, wherein the order to establish reliable communications channels between the stations, the system undergoes the following procedure: a first station computes from its stored model a propagation frequency window and determines a set of communications channels within the frequency window, the transceiver of the station thereafter monitoring the noise and interference present in the set of channels in order to reject channels having noise and interference levels higher than a predetermined level, and the first station establishing communications with one or more second stations on communication channels of the set in order to actively sound the channels in order to establish which channels are suitable for message transmission. In order to cater for disturbed ionospheric conditions a maximum usable frequency may be determined experimentally in a network setting up procedure or prior to any conversation between two or more stations wherein a series of active sounding test transmissions are carried out on a range of frequency channels between the stations.

Abstract: An anchoring strap (1) produced from a single layer of sheet metal forms an anchor upper part of a facade-panel anchor. A threaded rod (8) projects into an aperture (6) in the anchoring strap (1) and carries a nut (13) there which is supported via a washer (14) on an upper sheet-metal web (15). The sheet-metal web (15) is in its central portion (16) curved out from the plane of the anchoring strap (1), in one direction, approximately in the form of a semi-cylindrical shell. Located on both sides of the central portion are lateral portions (17) of the sheet-metal web (15) which are curved out from this plane in the opposite direction. As a result, tensile force is introduced centrically into the threaded rod (8). Located under the upper sheet- metal web (15) is an oppositely curved central sheet-metal web (19), below which an again oppositely curved lower sheet-metal web (21) is arranged, these latter being mutually supported in the axial direction. <IMAGE>

Title: Shut-off and/or control element for tapping molten metal melts from a metallurgical container
IPC: B22D41/14
Filed: 1989-04-26
Granted: 1992-11-11
Abstract: The present invention is drawn to a regulating device of a metallurgical vessel for regulating the flow of molten metal from the vessel. The device includes a fixed refractory part defining a first cylindrical peripheral surface of the device and a movable refractory part that is rotatable and/or slidable relative to the fixed refractory part and defines a second cylindrical peripheral surface sealingly engaged with the first cylindrical peripheral surface. An actuating device is connected to the movable refractory part for rotating and/or sliding the movable refractory part relative to the fixed refractory part. The cylindrical peripheral surfaces of the refractory parts are spaced apart from one another so as to define an annular gap therebetween. In order to ensure that during operation the refractory parts can be moved relative to one another by the actuating device while preventing the penetration of molten metal into the annular gap, each of the refractory parts has a coefficient of thermal expansion which, when the device is subjected to a high temperature corresponding to the melting temperature of a molten metal, causes a clearance fit to be established between the peripheral surfaces that is effective to prevent molten metal having a melting point at the same predetermined high temperature from penetrating between the peripheral sealing surfaces while allowing the movable refractory part to be moved relative to the fixed refractory part.

Abstract: Medical instruments, which may include brass, copper, aluminum, stainless steel, carbon steel, or plastic parts are microbially decontaminated (sterilized or disinfected) in an antimicrobial solution. To provide a long shelf life, premeasured doses of powdered reagents are sealed in an ampule until ready for use. The powdered reagents are selected such that they react in the presence of water to form a strong oxidant solution in an appropriate concentration to be effective as an antimicrobial. The preferred powdered reagents include acetylsalicylic acid and sodium perborate which react in the presence of water to form a peracetic acid solution. Moreover, these dry reagents form sodium metaborate and salicylic acid, both corrosion inhibitors to inhibit corrosion of metal parts of the medical instruments. The ampule may also hold a preselected dose of phosphate or other water soluble corrosion inhibitors and a wetting agent.
