Title: Recording and removing system for incompletely filled trays - uses transmitted light through bottom of tray, detected by optical receiver, to indicate presence or absence of product in tray
Inventor: GRUBE GERHARD
IPC: B07C5/34
Filed: 1979-08-31
Abstract: The system uses light transmitted through the bottom of a tray to indicate the presence or absence of a product in that tray. (The tray is covered with a top foil by the packing machine). The light source is located beneath the tray and the optical receiver is located above the tray. The optical receiver, detecting the transmitted light, has a receiver area that is greater than the area occupied by the product in the tray and facing the receiver. The amplitude of the receiver's output signal is monitored and used as criteria for removing a tray (because it contains no product). A comparator is used to compare the output signal with a reference. The comparator initiates removal and also causes a digital counter to move on one digit. The counter counts the number of trays removed.
Patent DE-2938116-A1 (DE)
Title: Resistance bridge measurements using micro-computer - measuring discharge time of capacitor which has been connected to imbalance voltage
IPC: G01R17/10
Filed: 1979-09-20
Abstract: The diagonal voltage on a resistance bridge (1) charges a capacitor (10) for a precise number of micro-computer clock pulses. The capacitor charge is thus an integral of the imbalance voltage. Identical resistors (15,16) are then switched in paralle with two arms of the bridge for the same number of clock pulses. The capacitor is then disconnected from the bridge, and the voltage across it is amplified and fed to window-discriminators (7,8). If the voltage is zero, the micro-computer registers a balanced bridge. If the voltage is measurable, the cycle begins again, but the resistors are switched for dissimilar times. This is repeated for increasing time differences until the voltage at the end of a cycle is zero. The time ratio for this last cycle is a measure of the imbalance, which is then calculated by the micro-computer.

Title: Pilot signal level detector for power line carrier - supervises interference frequency and gives alarm to indicate when transmission is unreliable
Inventor: TROLLMANN PETER ING GRAD
IPC: H04B3/46
Filed: 1980-04-15
Abstract: The circuit for power line carrier receiver equipment is used to give warning when the signal-to-noise ratio of the incoming signals reaches a level at which errors can arise. The pilot signal used for controlling the amplifier gain in the receiver (5) is additionally passed to a detector circuit (51). Here it is half- wave rectified and applied to a low pass filter (14) from which only the low frequency interference emerges. Further rectification (15) gives a dc level which is compared (16) against a maximum safe interference reference (17). If the reference value is exceeded, the comparator (16) gives an output to an alarm system (18,19,20,21). The output is time delayed (116) so that fast transient distortions are ignored. The reference level is typically set such that the alarms come up at a signal to noise ratio at which errors are just being avoided.

Title: Steel door frame for assembly on site - has separately made lintel and jamb posts joined by tongue and slot
Inventor: ALTSTETTER MANFRED
IPC: E06B3/988
Filed: 1980-08-22
Abstract: Steel door frames consisting of a lintel and two jamb posts are usually assembled by welding and then transported to the building site. In order to ensure that the frame retains its correct shape it is necessary to provide special equipment to protect it during transport and storage. These difficulties are overcome by making the lintel (1) and jamb posts (2) separately. Both members have similar cross-sections which are generally U-shaped. The lintel has a tongue (13) which projects downwards at each end and fits into a slot (21) in each of the jamb posts. Since the door frame is assembled immediately before installation on the building site, the lintel and jamb posts can be transported and stored separately so that much less space is needed.
