Title: Electronic safety cct. for signal lamps - switches on auxiliary lamp immediately upon failure of first lamp
Inventor: SCHMIDT GERHARD
IPC: H05B39/10
Filed: 1973-08-28
Abstract: In indicating devices used in hospitals, aircraft, and by the military and other important installations an immediate replacement must be arranged for a defective lamp as when for example, the filament burns out. No break in continuous service can be permitted which would allow the lamp to be changed. A series of signal incandescent lamps are connected to a common d.c. supply. Only one lamp is allowed to function at a time, the rest being regarded as reserve lamps taking over when the preceding lamp fails. When the first lamp fails the resulting break in the circuit closes a first transistor and switches on a second transistor to able a second lamp to operate. Should this lamp, in turn, fail a third lamp is switched on. Stages can be multiplied as desired to give sufficient time for maintenance or routine replacement of defective lamp(s).

Title: Liquid density transducer - measures axial displacement of diaphragm in two-part shell with reference liquid and two membranes
Inventor: GSCHWIND FRANZ XAVER DR ING
IPC: G01N9/26
Filed: 1974-01-23
Abstract: A densimeter for liquids such as wort during the fermentation process in beer breweries is a water-filled shell which is divided by a horizontal diaphragm into two parts, each with a connection closed by a membrane. when immersed in wort, a force must be exerted by the diaphragm to keep it in equilibrium against the static pressure difference of the membranes. This is done by an electromagnet. The axial displacement of the diaphragm is sensed and converted into a control signal for the current in the electromagnet coil to keep the air gap of the electromagnet constant. This current is a measure for the difference in density between outer and inner liquid. This measures the density of greatly polluted pasty or fermenting liquids in a simple way, yet produces continuous results with a high resolution. The instruments are robust enough for brewery use and require only an electrical cable for the installation. The densimeter can easily be cleaned and disinfected automatically. After slight alterations, it can also be used to measure pressures, pressure differences or fluid levels.
