Title: Input circuit for temp. sensors of heating system control circuit -  has common working resistor for operational amplifiers separately assigned to sensors
Inventor: SCHWEDLER NORBERT
IPC: G01K7/25
Filed: 1990-09-27
Abstract: The temp. sensors are used in a control circuit for a heating installation, e.g. radiators of a central heating system or water heaters. The temp.-dependent output voltage of the input circuit depends on only one of the temp. sensors. An operational amplifier (1, 2) is assigned to each temp. sensor (8, 12). The outputs of the operational amplifiers extend to a common working resistor (3). The common output (4) of the amplifiers is fed back to the negative inputs of the latter. Matched circuitry is connected to the positive inputs and the allocated temp. sensors. This for one amplifier (1) can be a voltage divider (9, 10) linearising an exponential characteristic curve of the temp. sensor (8). This divider circuitry for the other amplifier (2) can also be a voltage divider (13, 14) between the common output and a reference voltage (Ur). ADVANTAGE - Output signal of circuit is automatically derived only from the connected temp. sensor.

Patent DE-4035242-A1 (DE)
Inventor: DROSDZIOK ARMIN
IPC: F28B11/00
Filed: 1990-11-06
Abstract: The invention concerns the operational monitoring of a condenser (1) with a vapour chamber (2) through which the vapour to be condensed flows and of at least one of an arrangement with a plurality of tubes (3, 4) in the vapour chamber (2) through which a cooling fluid passes from an inlet (5) to an outlet end (6).

In addition, the inlet temperature of the cooling fluid at the inlet end (5), the outlet temperature of the cooling fluid at the outlet end (6) and the cooling fluid flow rate are measured at each selected tube (4). The measurements are evaluated to determine the heat flow coefficient of each selected tube (4) and the coefficients thus determined are assessed for diagnostic purposes. In particular, a signal is given when at least one heat flow coefficient differs substantially from a predetermined setting.

Title: Drawbar actuator with clear spindle bore - has only cup spring assembly and drawbar rotating with spindle while hydraulic release mechanism remains fixed
Inventor: MILLER HERMANN
IPC: B23B31/30
Filed: 1991-01-30
Abstract: The drawbar is in the form of a hollow tube sliding in the spindle. The clamping force is applied by a stack of cup springs encircling the spindle and acting between a collar fixed to the spindle and a clamping ring. The clamping force is transferred to flange fixed to the end of the tubular drawbar through balls which, by virtue of the geometry of the contact surfaces, provide a mechanical advantage and locking action. The whole of the cup spring assembly rotates with the spindle. Fixed to the machine frame is a hydraulic release mechanism consisting of two nested cylinders surrounding the cup spring assembly. The cylinders apply a tensile force between the spindle collar and clamping ring, thus compressing the cup spring stack, unlocking the balls, and moving the drawbar forward into the release position. ADVANTAGE - Clear space through spindle can be used for tool control and other functions. Compact design not requiring rotary seals. Spindle bearings not subject to clamping force.

The output signals of the movement detector circuit fed to a signal processing circuit (2) and a summation circuit (9) indicate whether a picture point block of e.g. 8.8 picture points is to be processed in static or dynamic mode. A second movement detector circuit can also be used which is fed with the chrominance components, permitting a separate, corresponding movement-dependent processing of the chrominance components. ADVANTAGE - Television system compatible with known composite television standards, with increased resolution.
