Title: Transducer location differentiation in monitoring networks - uses single supply transmission line with branched distributors having resistors and diodes in series
Inventor: JAUNICH GERD
IPC: G08B29/02
Filed: 1977-02-08
Abstract: The method is for differentiating between the various monitor locations in a distributed branched network, used typically for checking the humidity at a number of different points, or for security purposes, in which a single cable with branches, supplies all the monitoring points. Typically each monitor point (9) is supplied with current from a single transmission line pair (1) via a local diode (4) and resistance (3), the size of which is peculiar to that particular monitor location. A known current is passed down the transmission line pair (1) and the voltage across is defines the monitor point (9) being activated, or, equivalently, short circuited. A current of opposite polarity can be used to locate monitors attached directly to the transmission line pair. Two further alternative forms of the arrangement, one using a threshold defining zener diode (5) and the other diodes in both connection links between the supply line and the transducer may be used.

Title: Safety switch for food slicing machine - requires two separate operations to set machine in motion and uses catch mounted on slide attached to spring
Inventor: HARTKORN HANS WALTER ING GRAD
IPC: B26D7/24
Filed: 1977-07-26
Abstract: Food slicing machine is set in motion by a switch(10) actuated by a press button(7) fitted in the side of the machine. The operation of the switch is normally prevented by a catch(8) mounted on a slide(5) which is attached to a U shaped leaf spring(11). The slide(5) fits in a slot in the base of the slicing machine and can be moved by sliding a small key. This movement compresses the leaf spring(11) and allows the arm(9) of the switch(10) to slide over the smooth slope(12). Thus two separate operations are necessary to set the machine in motion which prevents inadvertent starting.

Title: Control of multilayer vapour deposition - by alternate exposure and check measurement of two test glasses
Inventor: STENGEL WOLFGANG DIPL PHYS
IPC: G01B11/06
Filed: 1977-11-11
Abstract: A measuring system for the mfr. of multilayer structures of alternating high- and low-refractive layers on transparent substrates by vapour deposition used two test glasses. These are alternately exposed simultaneously to a measuring light beam and to the rate of vapour deposition as the substrates. A changeover control ensures that one test glass receives the high and the other the low refractive layer. This clearly reveals maxima and minima in the intensity curve of the measurement signal so that the amplifier gain in the processor circuit requires no subsequent adjustment. Sensitivity and gain remain constant and noise interference with the signals is negligible.
