Title: Foam cleaning body with contoured work surface - has sharp-edged protrusions for more effective cleaning action when distorted
Inventor: KALBOW HEINZ DIPL ING
IPC: A47L13/16
Filed: 1975-03-27
Abstract: The cleaning or polishing foam body (10) is made from a soft flexible foam material with a contoured work surface having a number of protrusions (14) which have a sharp-edged outline, preferably rectangular or square in shape. Shaping of the protruding cams is preferably undertaken so that the sides of the protrusions are at right angles to their faces so that they have sharp edges. In this way, the cleaning effect of the foam body is increased since the resilient distortions of the foam body causes the inclined edges of the cams to scrape along the surface. The foam body is particularly useful for cleaning uneven surfaces having indentations and other areas which are difficult of access.

Title: Binary signal transmission between two control units - utilises instantaneous signals with valves between threshold levels corresponding to binary digits
Inventor: GEISSDOERFER WERNER DIPL ING
IPC: H03K19/018
Filed: 1975-07-25
Abstract: Binary transmission signals are applied to a transmitter which allocates instantaneous values of signals to be transmitted to the receiver to the transmission signal of binary values, so that instantaneous an value whose level is greater than a first or smaller than a second threshold level corresponds to the binary values "1" or "0". The receiver (EM) reverses the process. The transmitter typically includes a differential amplifier (T1), T2), so that inverted and non-inverted signals received from a gate element (G3) may be sent to further transistor stages (T3, T4) with collector terminals leading to the signal output through resistors (R10, R11).
Patent DE-2545382-A1 (DE)
Title: Camera with checkable aperture setting - uses indicator which glows if prevailing light is inadequate for setting selected
Inventor: GANSER JOSEF
IPC: G03B17/18
Filed: 1975-10-10
Abstract: To set the aperture, the test button is pressed, releasing the latch (20, 19) from the aperture setting ring (10), which is automatically returned by its spring (12) to the f11 setting. The ring, in turning, moves a density wedge (8) correspondingly in front of a photoresistor (6). Pressing the test button (25) switches on the light measuring circuit (switch 26). If, therefore, the diode (3) in the viewfinder (2) now glows, the f11 aperture is too small for the prevailing light. The user thereupon turns the aperture setting ring (10) until the light goes out, then releases the test button to latch the ring in this satisfactory position (20, 19).

Title: Toy helicopter worked by downward air jet - is furnished with plastic sleeve inside neck of balloon to improve airflow
Inventor: WESENBERG HANS-ULRICH
IPC: A63H27/26
Filed: 1975-10-25
Abstract: A toy helicopter (1) has a lifting force which comes from a toy balloon (4) whose mouth points vertically downwards (12) and whose neck passes through the overall centre of gravity of the helicopter. It has been found that the flight of the toy can take unintended forms if the neck of the balloon becomes puckered or twisted, as can easily occur. Consequently, a short length of smooth plastic tube is fitted into the neck of the balloon to hold it securely in place and guarantee the direct axial flow of the jet of air. If necessary, the new cylindrical tube is furnished with transverse partitions or radial ribs.
