Abstract: ABSTRACT "Four transistor static bipolar memory cell using merged transistors."          A bipolar memory cell of reduced size requires only four I2L operated transistors and three access lines.  Two current injection transis-tors supply operating current to two inversely operated flip-flop transistors and also function as load devices as well as coupling devices.  The three access lines conduct power to the cells as well as the signals for the write and read operation.  A write operation is performed by ratioing the currents supplied to a memory cell array such that only a selected cell is written.

Abstract: TITLE:  COUNTERBALANCED TOWER CRANE           Abstract of the Disclosure A vertical tower and pivoted upper boom are counterbalanced by a mobile counterweight member mounted on a self-propelled earthborn unit spaced a substantial distance from the tower in diametric opposi-tion to the boom.  The tower, which is pivotable about a vertical pivot axis, is connected to the counterweight by a first horizontal rigid spreader link and  by a second diagonal rigid spreader link.  The two links are respectively connected to the lower and upper ends of the tower.  In this manner, rotational torque is transmitted directly to both the lower and upper ends of the tower.  Both the tower and the boom can therefore be turned about the vertical pivot axis by operation of the self-propelled counterweight unit without the usual problems of having the tower "winding up" due to the rotational forces applied to it during turning of large loads.

Title: Method and apparatus for controlling  thrust in a gas turbine engine
Inventor: MARVIN IRA E
IPC: F02C9/28
Filed: 1979-02-23
Granted: 1982-08-31
Abstract: Abstract Gas turbine engine thrust is controlled by automatically adjusting compressor rotational speed with novel functions of engine inlet temperature to hold thrust to rated values for varying engine inlet tempera-ture conditions. Furthermore. compressor rotational speed is automatically adjusted as a function of engine inlet pressure to provide a thrust rating schedule which varies with altitude. Compressor corrected rotational speed is limited through a novel function of engine inlet temperature to protect against turbine overtemperature when the engine inlet temperature exceeds the flat thrust rating point.
