Title: Circuit generating narrow ultrasonic transmit pulses - has semiconductor component parallel to sonic generator having variable resistance dependent on generator voltage
Inventor: BRAUN ULRICH
IPC: G01N29/22
Filed: 1979-06-21
Abstract: The circuit provides very short pulses without reducing their amplitude. Simultaneously it reduces oscillations of sound generating elements. It consists of a transmit unit, generating a voltage surge, and a sonic generating component (5), to which a semiconductor component (6), e.g. a thyristor, a switching transistor, or an avalanche diode, is connected in parallel. The semiconductor component is blocked up to a moment of a preset h.v. appearing on e sonic generator component, while being forward switched from the moment of appearance of this voltage value, due to its reduced resistance. Typically, the sonic generator component is in the form of an ultrasonic converter of lead zirconate, or barium titanate. The circuit may be used for generating surge waves and applied in systems with transmit-receive testing heads.

Title: Photographic camera, in particular a technical or studio camera
Inventor: STARP FRANZ
IPC: G03B9/02
Filed: 1981-01-17
Abstract: Technical or studio cameras with a lens shutter have already been fitted with an auxiliary unit for the purpose of facilitating the diaphragm setting. In order to mount the diaphragm setting unit, which can be placed circumferentially on the shutter housing, use has been made to date of a screw connection, i.e. the carrier of said unit has been connected to the circumferential surface of the shutter housing by means of mounting screws. This type of mounting has proved to be time-consuming and therefore inappropriate for equipping folding cameras or flat-bed cameras, because of the need to mount and dismount the unit before and after each use of the camera, and also because of the need to keep a tool ready for tightening and loosening the mounting screws. In order to ensure simple mounting and dismounting of the diaphragm setting unit before and after the camera is used without resorting to a tool, provision is made for the purpose of holding the unit on the shutter housing of a detachable plug-in connection, which is preferably formed from a retaining support arranged circumferentially on the shutter housing and a plug pin attached to the carrier of the diaphragm setting unit and which enables the camera user to mount and remove the auxiliary unit in seconds.
