Abstract: In the process for preparing dental materials which contain, as essential constituents, a liquid, organic, polymerisable binding agent and a finely divided filler, such a filler is used which consists to 70 to 95% by weight of particles having a granule size of 0.7 to 25 microns and 30 to 5% by weight of particles having a granule size of 0.2 to 0.7 microns. The dental materials are particularly well suited for preparing agents for preserving teeth by polymerisation because, as a result of the novel size of the granules of the filler, more of the filler than previously can be worked into the binding agent and the mechanical strengths of the polymers are higher.

Abstract: A temperature supervising system comprising a temperature sensor which is designed to sense the temperature of the supervised component and to supply a signal representing the temperature, which signal is compared with a reference signal to produce an alarm or to interrupt the connection of the component to a supply source when the difference between the signal indicating the temperature and the reference signal exceeds a given value, for example zero. The reference signal is generated by a function generator which supplies a signal varying with time, which signal, in a period immediately after the instant the component is connected to its current source, increases according to any desired function, for example stepwise or linearly, from a low initial value to a higher output value.

Abstract: Title of the Invention:   MECHANICAL STORED ENERGY POSITIONING ACTUATOR A motor driven actuator, providing continuous positioning of an output shaft, and employing energy storage which allows the shaft to return to a predetermined position on failure of the input power source or other predetermined occurrence.  Drive motor torque requirements are minimized through sequential application of input torque to the energy storage and actuator load.  This arrangement insures that adequate energy storage for return of the output shaft is continuously available during normal actuator operation including alternate output shaft positioning. When utilized to operate a fluid control valve, the valve actuator combination provides a fail-safe valve which under emergency or other prescribed conditions provides return of the valve to a shaft condition from any normal operating position throughout the limit of the valve travel. The above functions are provided through the use of a simple highly reliable structure utilizing a reduced number of relatively simple components and a drive motor which can be sized for the output torque alone without additional torque requirements due to the presence of a stored energy device.

Abstract: Information-recording process in which a pulsed laser produces recording marks in the form of crisply-defined areas of surface relief on the surface of a recording medium such as APIEZON W wax, iodine doped epoxy resin, and other materials. The medium is selectively producable in different density states by cooling it at a selected cooling rate from the molten state, and can be switched between said states by controlled exposure to the laser light, thus permitting recording, erasing, and recording on the medium. The permits very small marks of less than 1 micron diameter to be produced using a diffraction-limited spot of light, and as surface relief of high aspect ratio can be obtained at low power levels, it is possible to achieve high packing densities and high signal to noise ratio at low energy costs.

Abstract: A liner for the mounting of an external catheter sheath on a penis whereby the sheath is secured in a liquid-tight manner to the penile shaft. The liner, in a majority of the forms thereof, includes alternately oppositely directed legs integrally formed at a common central portion. Variations include a single leg in each of the opposed directions, dual legs in one direction with a single intermediate oppositely directed leg, or multiple legs in each of the opposed directions. The legs are adapted for individual engagement about the penile shaft and, when wrapped, may be in edge engagement with adjacent legs, overlap adjacent edges, or be spaced therefrom. Selected portions of the liner, while providing a liquid- tight seal about the shaft, may or may not adhesively bond to the shaft throughout the full extent of the liner. The liner in turn will normally provide for positive engagement of the sheath therewith throughout the effective height of the liner. An additional variation includes end connected multiple spaced elongated strips which wrap, as a unit, about the penile shaft to provide alternating liner strips and gaps. Further variations include tapered liners with portions of variable thicknesses. <IMAGE>

Abstract: A unitary membrane-electrode assembly includes a structure with multiple layers having different overvoltages for the desired electrochemical reaction. The layer attached to the membrane has a higher overvoltage for the electrochemical reaction than the electrode layer attached to its upper surface thereby preferentially locating the electrochemical reaction zone a small but controlled distance away from the membrane surface. In an alkali metal halide or alkali metal sulfate electrolysis process the use of a unitary dual layer structure with a bonded remote electrode is particularly useful as a cathode side structure because it eliminates formation of concentrated caustic at the membrane surface. As a result, back migration of OH-ions is reduced and cathodic current efficiency is increased.

Abstract: A pair of differential amplifier stages are connected in cascade to form a multistage amplifier for signal amplification purposes. The base-emitter paths of current source transistors which establish the operating currents for the respective stages are connected in series across a common source of forward bias voltage. The collector-emitter path of an additional transistor is shunted across the base-emitter path of one of the current source transistors. As biasing of the additional transistor is varied, the distribution of gain between the respective cascaded stages is altered substantially without disturbance of the overall gain of the multistage amplifier.
