Title: Light corrected roller blind camera shutter - operates with non-parallel slot sides for even light transmission
Inventor: OHBA OSAMU
IPC: G03B9/34
Filed: 1978-03-16
Abstract: The blind type shutter of the camera has leading and trailing shutter blades which are released with a time delay to form a slot for the exposure. The trailing edge of the leading blade is curved to restrict the amount of light in the centre of the aperture and it can compensate for variations in light intensity in the exposure. The system provides a simple mechanism for ensuring an even illumination of the film, with an enchanced light intensity passing through the middle of the lens.

Title: Overvoltage protection of phase and neutral lines - is for LV distribution system and operates with lamp indication of state
Inventor: SCHIESSER RUDOLF
IPC: H02H9/06
Filed: 1978-03-25
Abstract: Each phase (R, S, T) and the neutral(Mp) are connected to a common rail (28) through spark gaps (16, 18, 20, 56) and fuses (22, 24-26, 58). Should an over -voltage occur it is limited by the spark gaps and, dependant upon current, the associated fuse may operate. A system of indicating lamps (36, 38, 40, 52) shows the circuit state. All lamps ON indicates all circuits made and healthy. Loss of a lamp, when not due to lamp failure, indicates operation of a spark gap with power or loss of a main fuse (10, 12, 14). The neutral is also protected against over voltages.

Title: Aerosol filter sepn. efficiency measurement - by test aerosol from pressure vessel passing measuring section and reference section
Inventor: KIESSLING WOLF DIETER DIPL ING
IPC: B01D46/42
Filed: 1978-11-04
Abstract: The separation efficiency of aerosol filters is measured by producing in a pressure vessel a spray pattern with a rotational symmetry to produce a test aerosol. Outlets distributed over a plane in the walls lead to one or several measuring set-ups, each consisting of a test specimen, an absolute filter, a flow meter and an adjustable restrictor. At least one outlet leads to a reference set-up with an absolute filter, flow meter and adjustable restrictor. The sepn. efficiency of aerosol filters, esp. for use in compressed air systems, can thus be measured with a high accuracy, using simple appts. and under conditions simulating field conditions.

Title: Capacitive touch-plate switch for household appliances - has diode and extra RC circuit to prevent RF interference disabling switch
Inventor: MEIERFRANKENFELD WENZEL
IPC: H03K17/96
Filed: 1978-11-30
Abstract: The interference, caused by RF radiation, is eliminated in a capacitive touch-plate switch by incorporating a reverse-biased diode (D1) in the line leading to the input of the comparator (4) that detects when the switch has been operated. The junction between the diode and the comparator's input is connected via a resistor (R1) to an extra dc voltage (U=). A capacitor (C1) is connected in series with this resistor. By an appropriate choice of values for the resistor, capacitor and the resistor (RD), forming a differentiator with the touch-plate capacitance (CT), RF interference picked up by the user's body is prevented from disabling the switch.

IPC: H05K7/20
Filed: 1979-05-12
Abstract: The heat-exchanger dissipates heat from cubicles containing electronic and/or electrical equipment, partic. those which are airtight or dust-tight.
