Abstract: Abstract of the Disclosure A moisture detection unit for sensing the moisture content of tobacco is disclosed.  A capacitor sensor forming part of a C.R. network is arranged so that the tobacco is passed through or near the sensor.  The capa-citance of the sensor is proportional to the moisture content of the tobacco, and this capacitance determines the frequency derived by an oscillator to which the C.R. network is connected.  The output frequency is inversely proportional to the sensor capacitance.  A frequency to voltage converter derives a voltage proportional to the frequency and this voltage signal is then passed through an inverter.  The inverter has an off-set which compen-sates for the standing capacitance of the sensor, to derive an output voltage which is proportional to the moisture content of the tobacco.  This voltage can then be used to drive a digital read-out.  Additionally, this voltage may be fed to control equipment associated with the tobacco water spray for varying the amount of water sprayed in accordance with the value of the voltage.

Abstract: ABSTRACT OF THE DISCLOSURE            A heat exchanger for solar collector apparatuses comprises two metal layers abutting each other and at least one metal pipe for a heat-carrying medium arranged between the layers.  The metal layers are cold-welded together on either side of the pipe to form heat-conveying fins and the pipe is cold-welded to at least one of the metal layers.  The exchanger has a greater total goods thickness at the pipe than at the fins to allow a comparative-ly high heat-carrying medium pressure. For manufacturing the heat exchanger two metal strips and a metal pipe are continuously fed between two rolls, of which at least one is provided with a groove corres-ponding to the pipe.  The roll pressure is selected so that the metal strips and the metal pipe are subjected during cold rolling to a thickness reduction of at least 60% during the passage between the rolls, so that the strips and the pipe are cold-welded together.

Abstract: ABSTRACT OF THE DISCLOSURE            An automatic releasing seat belt assembly utilizes a plate attached to a flexible belt portion of a seat belt.  The plate is provided with a rectangular opening.  A housing is attached to the other seat belt component having a compartment therein which is accessible by having a slot on one side and an opening on another side adjacent to the side of the slot.  The plate is inserted in the slot such that the opening in the plate is disposed adjacent to the opening in the housing.  Within the housing there is a camming plate utilizing a spring to bias upwardly and outwardly towards the opening in the housing a camming edge thereof.  The camming edge engages one side of the opening in the plate.  Thus, when the plate is inserted into the slot, the camming plate locks the plate into a given position. A flexible cable is disposed having one end engaged within the cavity of the housing and has a cam rod attached to the end of the inner cable portion thereof.  When the inner cable is retracted, the cam rod is pulled toward the camming edge of the cam plate so as to dispose it downwardly, releasing the cam plate edge from the plate thereby disengaging same.  The cam rod is activated by a solenoid coil, which in turn is sensitive to a plurality of sensors disposed about the interior portion of a motor vehicle, such sensors being responsive to an impact.  Upon impact, the sensors operate a timer which energizes the solenoid to activate the cam rod and thereby to release the cam plate.

Abstract: ERASE THROUGH TAB                              Abstract An electronic typewriter which has the capability of erasing characters automatically and which has the further improved capability of being able to back through unused space on the line, which results after a tabulation command, thereby allowing the repositioning of the type element over the characters typed prior to the tab command thereby allowing automatic erasure of those characters.  The improvement of the typewriter as described permits the retrieving of characters from an electronic memory and the use of that memory to control the erase cycle even where the carrier position and the character to be erased are on opposite sides of space without printed characters due to a tab command.  This is accomplished by the electronic control of the mechanical hardware and the ability to determine where the tab command was entered on the typing line and to prevent erasure cycles in the unprinted space until the carrier has returned to the point at which the tabulation command was entered.

Abstract: 18. MINIMUM BREAK/MAKE PULSE CORRECTOR          Abstract of the Disclosure Pulse signals, for example, dial pulses, wink signals or the like, are corrected to have minimum break and make intervals by employing digital techniques, thus making possible the use of large-scale integration components. A control signal  for determining the minimum break and make intervals is generated by utilizing a single digital counter and associated logic for controllably supplying first and second timing signals to the counter, the signals having frequencies related to the desired minimum break and make intervals. An output control circuit is jointly responsive to the control signal and first and second input signals representative of first and second states, respectively, of a supplied pulse signal for generating a corrected pulse signal having the desired minimum break and make intervals.  The control signal inhibits response of the output control circuit to the input signals for the desired minimum break and make intervals.
