Abstract: A temperature sensor is formed by mounting a force-sensitive resonator on a resilient or non-resilient base structure, preferably in an enclosure such that thermally induced expansions or contractions of the base structure apply a stress to the resonator. The resonant frequency of the resonator is measured to provide an indication of the temperature of the base structure and resonator.

Abstract: Separation of impure surface water layer, separation of mixture of impurities and water and method for implementation of discharging impurities separated, according to which local water level lowering required for flowing impure surface water layer through overflow spillway is performed in conformity with the Bernoulli formula by suction effect produced and maintained by increasing flow rate, while separation taking place in the same step is carried out by the transient decrease of flow rate, then by change of direction. By turbulent-free inflow without decrease of rate really excellent scraping efficiency can be achieved.

Abstract: A method for casting objects having complicated shapes from aluminum, zinc, non-ferrous metals and the like, for use in the industrial arts, comprises the steps of using a completely combustible and gasifiable foam material to constitute a form in which the objects are cast, removing a thin surface layer of the foam from those surface areas where a wall thereof could be damaged by flowing melted metal, where ornamental elements or profiles are to included in the objects prior to casting, or where the rate of flow of melted metal is to be decreased, substituting the removed foam layer by a protective layer of a material with a stronger structure, lower thermal conductivity, lower burning and gasifying rates than those of the material of the foam casting form, reconnecting the separated foam and protective layers by gluing, embedding the casting form into sand, pouring melted metal into a recess defined by the foam form while in the sand and delaying and regulating the burning of the foam during the pouring of

Abstract: The invention relates to a therapeutic aid suitable for the stabilization of limb bone fractures with surgery. Minimum three radially arranged reinforcing lamellae are extending from the pin shank, the width of which is decreasing from the pin head in the direction of the pin point. The longitudinal dimension reduction of the lamellae is sectional, but continuous within each section. Number of the lamella sections is minimum two, while at junction of the adjacent lamella sections recessed steps are developed toward the longitudinal axis of the pin.The medullary cavity pin according to the invention is applicable with very good result in case of femoral fractures below the buttock, because it is well adaptable to the varying cross section of the medullary cavity, it does not damage the bone, it gives sufficient stability, while the surgery is fast and simple.

Abstract: Cooling water is supplied to a load, e.g. a thermal-power station, from a source of water such as a lake or stream susceptible to changes in level. The system comprises a first pump drawing water from the source, a filter arrangement downstream of the first pump, a duct downstream of the filter arrangement and a second pump connected between the duct and the input side of the load. The downstream side of the load, from which the warm water emerges, is passed through a second duct and then preferably through a warm-water level control arrangement before being disposed in a sink or other basin. A connection between the discharge duct and the feed duct is permanently maintained and allows water to flow from the feed duct to the discharge duct or vice versa in dependence upon the relative quantities of liquid displaced by the pump. As a result, the water fed through the second pump can have its temperature adjusted by mixing with warm water automatically.
