Title: Microprocessor controlled electrical balance - by switching digital component power on and off continually to reduce power consumed
Inventor: KNOTHE ERICH
IPC: G06F1/26
Filed: 1979-06-13
Abstract: The electrical balance with a number of electronic components under the control of a microprocessor operates with less power than similar devices without any reduction in functional ability. This is achieved using one or more microprocessor-controlled switches which switch on and off the voltage supply to individual components as they are required or not. This can result in a considerably saving on average, e.g. the power consumed can typically be reduced to 20 percent of conventional loading. The method is pref. applicable to high resolution balances with battery power supplies and a quotient of maximum load to minimum display increment of 100000. The program may be held in more than one read-only memory, only one of which need be powered at a given time.

Title: Control for stepper motor operated call charge counter - employing two Darlington transistors to alternately charge and discharge motor circuit capacitor
Inventor: FORDAN GUENTER
IPC: H04M15/10
Filed: 1979-09-24
Abstract: The power supply (SV) voltage and current, derived from the telephone line (a,b) and also the complexity of the circuit, can be reduced by employing a Darlington transistor in the winding capacitor (C2) charge (T3,T4) and discharge (T5,T6) paths. An incoming 16kHz charge unit pulse is detected and smoothed (T1,C1), and triggers (T2) the charging circuit transistors (T3,T4). At the end of the pulse the charging circuit switches off and the discharge circuit (T5,T6) automatically conducts. Both operations in series move the stepper motor and counter (Z) forward one step. If germanium transistors are used (T4,T6) the power consumption in the steady state can be reduced further.

Title: Heat exchanger for regenerated gas turbine systems - has bellows forming blind passages balancing out loads on core (NL 29.4.80)
Inventor: MORSE CALVIN J
IPC: F28F9/00
Filed: 1979-10-24
Abstract: A large number of compressed air flow channels extend in intimate proximity along selected parts of the head pipes of a heat exchanger of the plate-rib type, so as to lead the heat exchanging medium around selected zones of the circumference of the exchanger. Arrangements are provided to join the flow passages between the inlet and outlet header pipes, in heat exchanging contact with hot gas flow channels in the heat exchanger, as well as to connect the air flow channels with the interior of the header pipes at selected points around the circumference of the header pipers, so that part of the compressed air fed through into them passes through the flow channels. Used for high performance plate regenerators of great weight as used e.g. in gas turbine compressor systems for gas pipelines. The heat exchanging arrangement is designed so that the high mechanical and thermal loadings occurring during operation are diminished, to allow the heat exchanger core to absorb these loadings and avoid high degrees of stress. An optimal rigidity of the arrangement accompanied by great flexibility is thus achieved. Heat exchangers of this type are used in regenerated turbine systems in the range of 5,000 to 100,000 H.P. The exhaust gases have a temp. is approx. 590 degrees C and heat the compressed air to 480 degrees C. The regenerator runs for 120,000 hrs. and 5,000 cycles without planned overhaul and has a life of 15 to 20 years of normal operation.
