Abstract: The preparation of highly densified ceramic bodies by sintering certain curable organopolysiloxanes filled with silicon carbide powders, metal-containing sintering aids and organopolysiloxane curing agents is described. Such highly densified ceramic bodies can be prepared by either a pressureless or a hot press sintering process. The compositions of this invention can be formed into desired shapes and then sintered to form ceramic, shaped bodies with high densities. One advantage of the present invention is that the green bodies have relative high strengths and thus can be easily handled and, if desired, machined before sintering. The curable organopolysiloxanes useful in this invention must yield a ceramic char which contains free or excess carbon in addition to carbon in the form of silicon carbide upon pyrolysis to elevated temperatures.

Abstract: To detect a physical parameter, a resonator is connected to a body which changes in dimension when subjected to the parameter. Thus, when the body changes in dimension in response to the parameter, the resonance frequency of the resonator is modulated thereby. Such modulations are detected optically to detect and measure the parameter. In the preferred embodiment, the resonator transmits light and light is applied to the resonator so that the light supplied is transmitted through the resonator and so that the modulations of the resonance frequency also modulates the intensity of the light transmitted by the resonator. The modulations of the intensity of the light transmitted by the resonator is detected to detect the parameter.

Abstract: The invention relates to a method for producing a helically profiled hollow body from a metallic material, in which a rotatably mounted drawing die having obliquely cut grooves is made to act on a cold hollow body with a smooth cylinder wall and the cross-section of the hollow body is reduced in the process. In order to provide a method and a device with which it is possible to produce in a simple and economical manner a thin-walled tube having a twisted profile over the entire wall thickness, it is proposed that to produce a tube which, in cross-section, has a corrugated profile over the entire wall thickness, a smooth tube with an s/D ratio in the range from 0.015 to 0.080 is drawn to a smaller diameter through the rotatably mounted drawing ring having obliquely cut grooves, the length of the envelope curve of the outer profile of the profiled tube being approximately equal to the circumference of the smooth tube and the wall thickness remaining virtually unaltered.

Abstract: The invention concerns a roll (1) adjustable in zones. The roll comprises a stationary roll axle (3), around which the roll mantle (2) is arranged revolving. The deflection of the roll mantle is regulated by means of glide shoes (5) supported on the roll axle (3) and acting upon the inner face (4) of the roll mantle (2) in the direction of pressing of the roll (1), said glide shoes being loaded by means of a loading produced by pressure fluid by means of pistons (8) placed in cylinder bores in the central axle (3) underneath the glide shoes (5). Adjoining glide shoes (5) in the roll are, at least in pairs, sealed (6) relative each other, being displaceable in the radial direction of the roll (1), so that flow of fluid between the glide shoes (5) and the inner face (4) of the roll mantle (2) is substantially prevented over the lateral ridges on the glide shoes (5) sealed (6) relative each other. Hereby, the power requirement of the rotation of the roll can be made lower.

Abstract: For the monitoring of digital telecommunication transmission devices during operation, said devices contain additional processor units which accept the fault reports and convert them into telemetry signals. Because of the aimed for interrogation of individual processor units, the latter are addressed, one processor unit functioning as master and the other as slave. After the repair or new installation it is desired that the new addressing of all the processor units can be carried out under the control of a slave. For this purpose a processor unit switched as slave transmits an appropriate instruction telegram either in the direction from which it has received call-up instructions or, if said instructions have not been received yet, it initially transmits said instruction telegram in a transmission direction, then waits for a suitable period of time to determine whether a master has been activated for addressing and, if this is not the case, transmits the instructions in the opposite transmission direction. <IMAGE>

Abstract: The invention relates to a device for monitoring the operational state of an accumulator (1) which is continuously connected to the power system and to the load (3) via a charging rectifier (2) in standby parallel mode. To make a defined statement on the operational state of the accumulator (1), a measuring device (4) is arranged in parallel with the accumulator (1) which causes a defined drop in the power of the charging rectifier (2) for a predeterminable time at basic load and which records the discharge characteristic (E2) produced during the discharging of the accumulator (1) occurring as a result. The charging rectifier (2) is then operated at a power exceeding the basic load by a defined charging current until the voltage at the beginning of gassing of the accumulator (1) is reached and the resultant charging characteristic (L2) and the subsequent drop to the charge maintenance voltage is recorded. The overall charging characteristic (E2, L2) is compared with the model-related reference characteristic (E1, L1) in the new condition of the accumulator (1) concerned. If there is a defined deviation, a signal is output. <IMAGE>

Abstract: In techniques for detecting nucleic acid material, there is a risk of contamination during unstoppering of reaction containers and transfer of liquids used in such reactions. This is because aerosols are produced during such unstoppering and transfer, which may contain some amplified nucleic acid material. Described herein are improvements in a disposable chemical reaction pack (10) and method for examining fluids using such a pack, in which liquids can be reacted and examined without the need to unstopper the reaction container and transfer the liquid to a further container for examination. The pack (10) comprises a first chamber (20) into which liquid to be examined is first inserted and sealed. This chamber (20) is connected to a second chamber (24) in which the liquid is examined. A rupturable seal (34) is provided between the first and second chambers (20, 24), which allows liquid to flow from the first chamber (20) into the second chamber (24) once linear pressure has been applied to the liquid in the first chamber (20). Advantageously, an expansion chamber (22) is provided intermediate the first and second chambers to control the velocity of liquid transfer from the first chamber (20) to the second chamber (24).
