Patent DE-3207286-A1 (DE)
Title: Water-metering device for WCs with flushing cistern
Inventor: HINTSCHES GEB ZINGSEM
IPC: E03D1/14
Filed: 1982-03-01
Abstract: The invention relates to a flushing cistern for WCs of the original type having a water-metering device and to the metering device (9) to be retrofitted into already existing systems (Fig. 1, Sheet 9). In conventional flushing-cistern systems, the technique is based on the fact that the weight of water of the filled flushing cistern keeps the outlet valve (8) closed. If the outlet valve is mechanically opened by means of a releasing device (5), the water flows out. A float mounted in the region of the stand, safety and overflow pipe (6) causes the outlet valve to close again only after complete emptying of the flushing cistern. The invention is now based on the fact that the buoyancy of this float can be interrupted in any desired phase of the water removal, so that continuous adjustability from three litres to complete emptying of the flushing cistern in one or more gushes is possible, as required. This takes place due to the fact that a round bar (7) which is adapted and weighted to overcome the buoyancy is embedded in the stand, safety and overflow pipe (6). The centring of the round bar, required for trouble-free functioning of the closing mechanisms, is effected by two flexible centring buffers (11) which are captively fixed to the round bar. The structural nature of the buffers (13, plan view) allows the round bar to be fitted without dismounting any parts of the flushing cistern and does not impair the safety function of the overflow pipe. The round bar is suspended from a spring (10) which, as a result of its dimensions, allows for all tolerances in the dimensions of overflow pipes. The construction thus equipped means that the water removal from three litres upwards is identical to the duration of actuation of the releasing device. In the event of extremely low consumption (mains failure, technical fields, laboratories), a quantity of water under three litres can be removed due to the fact that, in addition to the round bar, a likewise correspondingly weighted ring is placed (9) on the overflow pipe. Owing to the uniform weight distribution of the ring, its use does not have a disadvantageous effect on the vertical operation of the mechanisms which are influenced by it. Furthermore, tolerances in the thickness of the pipe are allowed for by springs (15) arranged inside the ring. <IMAGE>

Title: Measuring head for deductive thermodiagnosis
Inventor: WILDE EKKEHARD DR ING
IPC: A61B10/00
Filed: 1982-05-28
Abstract: In order to improve the detection of local temperature increases in the physiological tissue or temperature differences with respect to the neighbouring tissue, or to a selected tissue reference region, such as occur in the case of breast cancer, use is made of a matrix-shaped arrangement of high-resolution metal/semiconductor calorimetric counting gates (detectors) each having a thermal capacity and thermal conductivity defined by design. When the measuring head is applied, an equalisation process based on the interaction between the physiological tissue and measuring head is set in train and generates a directed thermal flux from the tissue to the measuring head. The individual detectors with integrated temperature sensors quantify the thermal flux density and relay these measured values via a downstream electronic system to a measured data processing system for the purpose of storage and evaluation. Because of the heat dissipation produced by the measuring head, it is possible for heat components of tissue layers situated further inside to be more effectively detected and measured.
