Abstract: A solid state overload relay protective apparatus for electric motors which includes not only the overload feature, but the additional features of underload and single phase protection. Small current transformers for sensing the current flow in each phase of the motor are utilized, like those found in the ground fault sensing art because a current-to-voltage converter circuit reflects a short circuit back to the secondary of the transformers. The signal from the current transformers which is proportional to the sensed current in the motor is fed through the converter, a scaling and summing amplifier adjustable for a wide range of motor full load currents, an ideal diode peak detector, a time integrator amplifier, to one input of a comparator circuit having a trip reference voltage signal at another input. The comparator provides an output signal to a transistorized trip level circuit that deenergizes a coil of an overload relay opening its contacts and interrupting power to the motor.

Abstract: The present invention relates to a process for making semi-conductor components on an amorphous substrate, comprising two phases, wherein, in a first phase, the substrate is introduced into a deposition chamber and a uniform deposit is made of four successive primary layers on all this substrate, without contact with the outside atmosphere: a first layer of protective insulating material, a second layer of semiconductor material, a third layer of insulating material, of smaller thickness than the first layer, and finally a fourth layer of a metal; and, in a second phase, the substrate coated with these four layers is withdrawn from the deposition chamber and the last three layers are subjected to photoetching and ancillary deposition operations, which are appropriate for the structure of the component to be obtained.

Abstract: A metal anchor tube is driven into the ground or blacktop and defines a cavity which receives the lower end portion of an elongated cylindrical flexible marking tube extruded from a resilient plastics material. The upper end portion of the marking tube supports a light reflecting member which may be in the form of a reflective sheet located within the marking tube and visible through an opening or window within the tube. In one embodiment, the lower end portion of the marking tube is releasably coupled to the anchor tube by an internal wedge plug which compresses the marking tube against the anchor tube and is inserted and removed by means of a tool. In another embodiment, the releasable coupling is formed by an anchor tube having tabs which project inwardly into corresponding holes within the flexible marking tube.

Abstract: A process for adjusting the amount of yeast introduced into a fermentative liquid comprises periodically taking a sample from a mass of suspended yeast maintained in movement in a closed circuit, subjecting the sample to fermentation by adding a nutrient element, and adjusting the supply of yeast to the liquid in accordance with the fermentative power of the treated yeast sample. The implementing plant comprises a container having a conical bottom containing yeast suspended in a liquid, a pipe connecting the bottom of the container to a fermentation tank, and a regulating or adjusting pump for supplying yeast from the container into the tank. A pipe for recycling the suspended yeast in the container is provided, as well as means for ensuring, during a predetermined time interval, the recycling of the suspension of yeast from the bottom of the container to the upper part thereof.

Abstract: Animal cells are grown in a vertically disposed cylindrical vessel containing a stack of parallel spaced-apart discs inclined at least 5.degree. from the horizontal and mounted to a rotatable axial shaft. The vessel is closed by a top plate having a plurality of inlets and a bottom plate with an outlet, and contains an external pumping loop for circulating contents of the vessel from the bottom to the top of the vessel. Growing of the cells is carried out by substantially filling the vessel with a mixture of animal cells and growth medium, allowing the cells to settle on the disc surfaces and then rotating the axial shaft at a speed of at least 5 rpm while continuously circulating the vessel contents from the bottom to the top of the vessel. This process and apparatus provides efficient mixing and ensures a homogeneous system within the vessel.

Abstract: In manufacturing optical transmission filters having double-refraction elements, extreme care is usually necessary to provide the desired phase delay. To simplify the manufacturing process while still achieving accurate phase delay, a filter is provided with at least one double-refraction element comprising a single-mode optical filter mounted between polarizers. The double refraction of the optical fiber is sufficiently weak so that the .lambda. length within which light beams propagating with orthogonal polarization states in the fiber are mutually delayed by 2.pi., is at least 1 cm. In one embodiment, the optical fiber comprises alternating sections which produce linear double refraction with sections which produce elliptical double refraction.
