Title: Pump with control valve downstream - has voltmeter and ammeter detecting position of valve to stop and start pump
Inventor: RIEMER OTTO ING GRAD
IPC: F04B49/06
Filed: 1980-08-02
Abstract: A pump serving a process system has a control valve downstream of it. When the control system closes the valve the pump would continue to run unless complicated additional controls were installed. A voltmeter and an ammeter in the circuit to the pump and valve distinguish the condition of voltage and current flowing from the condition voltage and no current.

Title: Electrically heated stand for drafting table - enables use of slow drying inks and contains internal heating resistor
Inventor: LANGE ARTUR
IPC: B43L13/02
Filed: 1980-11-11
Abstract: A heated stand (1) for a drafting tables (2) of all types is designed for accelerated drying of the drawings. Rapid drying is achieved even when slowly drying inks are used on papers and foils of low absorbency. The stand has a heated resistor inside it which maintains it at a suitable temp. The resistance (3) is denser near the edges (3a) of the table so as to compensate for the higher thermal radiation at the edges and hence ensure uniform drying. The use of slow drying inks helps to avoid drying up of the pens used, yet the drawings can be dried faster than with fast drying ink and unheated tables. Losses of heat to the atmosphere and thermal loads on the table are small.
