Title: Paving comprising floor-covering slabs
Inventor: BEIER GUENTER ING GRAD
IPC: E01C9/08
Filed: 1982-05-21
Abstract: The invention relates to an improvement to pavings which can be laid by machine and comprise foldable paving sections which consist of mutually hooked, detachable hexagonal individual slabs, according to Patent Application P 31 25 690.2. In the case of pavings of this type, deficiencies relating to the force transmission of individual slabs at the connecting edges of the articulated connection of the paving sections were found. These deficiencies were solved in an effective way by means of two projections on the initial slabs and by using very simple but sensibly constructed and expediently arranged hooked slabs on the end slabs, which resist very high loads without deformation.

Title: Method for measuring the volume of blood flowing in optically accessible blood vessels
Inventor: VILSER WALTHARD DIPL ING DR
IPC: A61B5/0275
Filed: 1982-06-02
Abstract: The method for measuring the volume of blood flowing in optically accessible blood vessels, preferably in human retinal vessels, has the object of considerably reducing the measurement inaccuracy, which is mainly due to eye movements, when determining the volume of blood flow over the minimum running time difference of the indicator, of making the determination of the minimum running time difference of the indicator independent of the signal maximum and of considerably improving the preconditions for automation of the entire measurement and evaluation process, as well as of making possible simultaneous measurement of vessel diameter and running time difference of the indicator. The essence of the invention is the utilisation of the alternating radiation signals produced by at least two measurement surfaces vibrating at right angles to the vessel course as measurement and control signals, and by utilising the phase shift obtained on corresponding spectral tuning of indicator, illumination and measurement path of the measurement signals as the time of appearance of the indicator under the measurement surfaces. The method can be applied wherever velocity and throughflow in optically accessible vessels are to be measured with an indicator.

Title: Electrically heated hot-water heater
Inventor: ORTLINGHAUS ULRICH
IPC: G05D23/24
Filed: 1982-11-26
Abstract: The present invention relates to an electrically heated hot-water heater having a store and a through-flow heater, both of which can be heated by electrical resistors, and having a temperature regulator. The present invention is based on the object of carrying out power control of the store/through-flow heater unit without emitting interference pulses to the supplying network. The object is achieved in that the temperature regulator for the through-flow heater switches proportions of the electrical power which are not required to the store. In consequence, it is possible to meter precisely the power which is to be emitted to the through-flow heater, proportions of the power which are not absorbed there being supplied to the store. This system operates without any feedback effect on the supplying network. The main field of application of the invention is in the heating of industrial water.
Patent DE-3244640-A1 (DE)
Title: Method and process for producing workpieces and tools of high hardness throughout the volume
Inventor: OTILLINGER FRANZ
IPC: C23C4/137
Filed: 1982-12-02
Abstract: The production of workpieces and tools of increased hardness throughout the volume has hitherto been feasible only by using highly and very highly alloyed and hence expensive steel grades. When using low-alloyed or unalloyed cheap materials, it has hitherto only been possible to increase the hardness of a thin surface layer by thermochemical surface hardening. The present invention now makes it possible, by using metallic powder granules or thin metal foils which are first subjected to a thermochemical hardening process, to produce tools or workpieces of high hardness right into the core by sintering or brazing. In this case, the particle diameter or the layer thickness is selected such that it coincides with the depth of diffusion of the hardening elements. This novel process can be used for producing workpieces and tools of high hardness right into the core and for applying a hardened layer to worn-down tool surfaces.

Title: Signal transmitter
Inventor: BOPP ACHIM PROF
IPC: G08B3/10
Filed: 1982-12-30
Abstract: A signal transmitter with time-delayed triggering as a warning device for domestic and industrial devices of all types is proposed which has several switching stages which drive a piezoelectric sound generator. At least two signal oscillators of different frequency are provided which are followed by a delay circuit and the sound transmitter. In the warning case, a supply voltage is applied to the input of the switching stages, the delay circuit applying the signal voltage generated by the two signal oscillators to the sound generator only after a predeterminable time after the supply voltage has been applied. In this process, each signal transmitter is formed by a quadruple Schmitt trigger with two inputs each, apart from the input stage. <IMAGE>
