Abstract: TEMPERATURE SENSING CIRCUIT ABSTRACT OF THE DISCLOSURE             An improved temperature sensing circuit is disclosed comprising a power supply which forward biases a diode sensing element to control the gain of an oparational amplifier.  A temperature change causes the resistance of the diode to change, which changes its current flow.  Since the anode of the diode is connected to the operational amplifier, the result is that the operational amplifier has a very linear output voltage proportional to temperature.

Abstract: Abstract of the Disclosure A ring laser gyroscope having a triangular block con-figuration is dithered about its center of gravity.  An optical wedge attached to the output mirror allows the center of support to include the line of symmetry of the block, thereby reducing temperature gradients, which could cause output signals in the absence of an input angular rate across the instrument.  The optical wedge, a mirror and a beamsplitter form an interfero-meter to compensate the output signal of the ring laser to pro-duce an output free from influence of the dither motion.  The mirror and beamsplitter are adjustable to allow for small corrections necessary to exactly compensate the dither-motion and to achieve 90° phase shift between the outputs from photo-detectors.

Abstract: MICROPROCESSOR-CONTROLLED ADAPTER          CIRCUIT FOR REAL-TIME CONTROLS, IN PARTICULAR FOR PRINT HAMMER CONTROLS                     Abstract Microprocessor-controlled adapter circuit for real-time controls, in particular for print hammer controls in line printers with revolving type carrier with two asyn-chronously driven FIFO buffers (FIRST IN, FIRST OUT).  The first FIFO buffer contains time values (e.g., firing times for the print hammers) and the second FIFO buffer control information associated with these time values (e.g., print hammer address, control commands for the print hammer).          By a request circuit (e.g., counters), the time values are successively read from the first FIFO buffer and fed to a gate circuit for switching the control information, associated with these values, from the second FIFO buffer for controlling the output values; a method of determining the firing times of the print hammers uses a reduced table in which for each character in each print position the posi-tions (time values), in which the character is to be printed, are stored only for some displacement values of the revolv-ing type carrier relative to the printer frame.  For the remaining displacement values, the time values for charac-ter printing can be determined by division, using the table data; mechanical or electrical tolerances influencing the firing times of the print hammers are compensated for by accommodating in the table additional correction delay values for the print hammers, thus eliminating adjustments.

A damping stop is arranged at a head end of a hydraulic jack in the form of a bushing made of a synthetic material, typically plastics.  The purpose of this bushing is to damp movement at the upper travel limit of the elevator which corresponds  to the stopping point of the elevator or lift cabin at the upper end of its travel.  The synthetic material bushing is compressed between a flange of a piston and a lower abutment or contact surface at a cylindrical insert of the jack until the internal pressure assumes a predetermined value.  For uniform deformation of the synthetic material bushing over its entire length steel stabilizing rings are  disposed  circumferentially  thereof  substantially equidistantly from each other.  The intermediate spaces or regions of the synthetic material bushing located between the stabilizing rings thus are subjected to approximately the same increase in their outer diameter.  After release from the load the synthetic material bushing again assumes its original shape when the lift or the like is lowered.
