Title: Material cooler with recycling of cooling gas
IPC: F27D15/02
Filed: 1971-11-04
Abstract: A cooler for hot material such as cement clinker with an arrangement for recycling cooling air. The cooler includes a housing divided into an upper material chamber and a lower plenum chamber by a gas permeable grate which supports and advances the material through the material chamber. Ambient cooling air is blown through the hottest and the coolest material. Two air recirculation circuits are employed. The ambient air blown through the coolest material is divided so that a portion goes to each recirculation circuit. One recirculation circuit returns air to the plenum chamber at a point where it will pass through the material to be cooled and then be conducted to the furnace. The other recirculation circuit returns air to the plenum chamber at points where it will pass through the material and some of it will be conducted to a furnace, while the remaining air will be returned to the recirculation circuit. An indirect heat exchanger is mounted in one of the recirculation circuits.

Title: Transistorized magneto ignition system for internal combustion engines
IPC: F02P1/08
Filed: 1973-08-27
Abstract: Diodes in series with a switching transistor and conducting in the same direction, interposed between the switching transistor and the primary winding of a magneto armature, are used to establish a steady voltage drop during conduction for application over a resistor to the base of the switching transistor to keep the transistor conducting during positive half waves of the magneto generator, except when the transistor is switched off to interrupt the primary current by a control signal. The high voltage for the spark is produced by a secondary winding on the magneto armature. The control signal may be switched on and off by the output of a magnetic pulse transmitter and powered by a capacitor charged by negative half waves of the magneto generator. The system that produces a spark for every positive half wave utilizes a voltage divider containing a Zener diode to generate the control signal when the Zener voltage is reached, and temperature compensating diodes are also provided in this voltage divider.
