Abstract: To make a space-keeping profile, especially one for thermopane glass, a hollow section (2) is bent in each of the corner regions of the profile, for example with four corresponding bends of about 90 DEG , in order to form a square or rectangular profile. The hollow section (2) is first of all filled with desiccant, during which procedure it can be arranged in a tilted position. At its lower end, it is sealed, for example, with a straight connecting piece (9), by means of which it is connected to a further hollow section (2) or, if the length of the hollow section (2) corresponds exactly to the profile circumference itself, it can be sealed. The desiccant (3) is introduced into this hollow section (2) at the upper end (12), after which it is laid in an approximately horizontal position and fed to a bending device and finally bent to form the profile. According to the invention, the hollow section is filled completely, although, if required, it may also be filled only partially, and then partially emptied again to give a reduced degree of filling, and the partial filling which it contains is distributed over its length with the hollow section (2) in a horizontal position and the hollow section is then bent. The partial emptying and/or the distribution of the partial quantity of desiccant contained in the hollow section - in particular after partial emptying has taken place - can be distributed with the aid of a vibrator (10). The vibrator (10) can shake the hollow section (2) backwards and forwards with the desiccant quantity contained in it in an approximately horizontal direction in the direction of alignment of the hollow section. The partial quantity of desiccant discharged can be measured using an appropriate measuring device in order thereby to determine the partial quantity remaining in the hollow section and, after partial emptying, to switch over the vibration process automatically to a mode which gives the most uniform distribution of the remaining desiccant in the hollow section (2).

Abstract: A modem voice/data mode switching arrangement is disclosed whereby a modem (1) automatically switches between a voice mode and a data mode without the modem user being required to perform any manual triggering step or act. According to the invention, once a voice-mode connection with another modem has been established, the modem monitors for the presence of a predetermined answer-­back tone on the line and, in response, switches to the data mode. Having switched to the data mode, the modem monitors for the loss of data carrier on the line and, in response, switches back to the voice mode. Thus arranged, the modem can automatically switch between the voice and data modes while communicating with any other modem that uses a compatible data carrier and the conventional ABT.

Abstract: A matrix controlled device and method comprises a conduit having an upper opening, a bottom outlet and an optional sidewall opening at a level intermediate the level of the upper opening and the bottom outlet. A flow control matrix plug is positioned in the conduit at a level between either the sidewall opening, when present, or upper opening, and the bottom outlet. The flow control matrix plug determines the rate at which liquid flows through the plug. By varying the pore density, pore size, dead volume, length, and elevation of the matrix, delay of the flow rate and initial flow of liquid from the respective conduit can be controlled. The size of an upper opening can be reduced to control air flow rates therethrough, and the size and elevation of a sidewall opening can be selected to control liquid flow rates therethrough. The device may be in the form of an assay device which additionally comprises a reservoir having sidewalls and a bottom and a plurality of the conduits positioned in the reservoir and extending through its bottom. In such an assay device the method for delivering a predetermined volume of liquid to a reaction zone comprises introducing liquid into one or more of such conduits, each conduit have a matrix plug therein at a level below the level of liquid introduction. Each matrix individually delays the first release and rate of delivery of the liquid in the conduit.

Abstract: A data processor (10) is provided for reloading deferred pushes in a copy-back cache (16). When a cache "miss" occurs, a cache controller (14) selects a cache line for replacement, and request a burst line read to transfer the required cache line from an external memory (26). When the data entries in the cache line selected for replacement are marked dirty, the cache controller (14)"pushes" the cache line or dirty portions thereof into a buffer (22b), which stores the cache line pending completion, by a bus interface controller (20), of the burst line read. When the burst line read terminates abnormally, the data cache controller (14) reloads the copy-back cache (16) with the cache line stored in the buffer (22b). The reloading of the copy-back cache (16) avoids the potential for multiple concurrent exception conditions, and eliminates the problem of unnecessarily removing an otherwise valid cache entry from the cache (16).

Abstract: A pressure compensating lung balances pressure between open and closed environments which are substantially isolated from and independent of each other, for example, the Earth's open environment and the closed environment of a second, smaller closed ecological system, Biosphere 2. The lung has an airtight housing and a barrier which includes a flexible membrane, one side of which faces Biosphere 2 and the other side of which faces the outside, with a central pan the perimeter of which is surrounded by the membrane. The membrane has approximately the shape of a surface of a torus. It deviates from a toroidal shape sufficiently to avoid substantial circumferential tension in the membrane. The weight of the pan exerts a positive pressure on the atmosphere in Biosphere 2 for preventing inward leaks. The pan and membrane are protected by a weather cover which can be sealed against the outside environment so that a fan can affect the air pressure from the outside acting on the membrane, and hence the pressure difference between the inside of Biosphere 2 and the Earth's atmosphere.

Abstract: An advanced optical sensor (10) for determining the stand-off distance from a trajecting container to a target (18) utilizes various checks and filters to eliminate false detonations caused by glint and counter-measures. The sensor (10) is comprised of a transmitter (12), a receiver (14), and a wave generator (16). The wave generator (16) generates a unique wave form which is relayed to both the receiver (14) and the transmitter (12). The light emitted from the transmitter (12) follows a pattern defined by the wave generator (16). When light is received by the receiver (14), a synchronous detector (38) coupled to the wave form generator (16) determines if the return light has a pattern correlating with the unique wave form from the wave generator (16). If so, the associated electric signal in the receiver (14) must pass a predetermined threshold for a predetermined period of time before the sensor (10) will generate a detonate signal.
