Title: Ring line arrangement paralleling two sw-transmitters - tunes equal positions of all quarter wave lengths branches to harmonics
Inventor: BEHNE FRITZ DIPL ING
IPC: H01P5/22
Filed: 1973-09-17
Abstract: The ring line circuit for paralleling of two in-phase feeding SW transmitters to one aerial is arranged so that quarter wave length ring line branches lie between the first transmitter, the aerial, the second transmitter and the dummy load and that the branch between the dummy load and the first transmitter is tuned to three quarter wave length. The circuit is characterised by the realisation of an equal portion of each branch of the ring line as shift adjustable telescopic line and in series with it the electrical length increasing additional component. The three quarter wave length branch may be a quarter wave length line with polarity reversal. The equal portions of the branches may be tuned to a harmonic and the additional component may be a fixed length of line or a squint angle switch with by-pass line. The circuit permits by simple constructional changes to cover the entire SW range.

Title: Manual or motor powered camera shutter control - includes safety interlock to prevent double exposures
Inventor: HEIL WALDEMAR
IPC: G03B17/42
Filed: 1973-09-28
Abstract: The shutter is operated by a central control shaft operated either by a manual release button or bya motor driven cam. The shutter setting lever operates on a button which controls microswitches which prevent the action of the motor driven shutter until the lever is returned to its rest position. similarly a cam on the shaft disconnects the motor drive when the manual button is pressed. This means that the cam-camera can be used manually when the motor drive is attached without simultaneous operation of manual and motor release blocking the shutter action, and double exposures are prevented.
