Title: Pulse width-period ratio detector - uses saw-tooth generator and sample and hold circuits for ignition timer
Inventor: FAUSER EDWIN ING GRAD
IPC: G01R29/027
Filed: 1978-11-15
Abstract: The circuit measures the ratio of the pulse width (TE) and the period (T) of a square wave signal. It is used for ignition timing control in an automobile. The rising flank of the signal is used by the control circuit to release the gate of the saw-tooth generator. The generator output increases until the end of the signal period (T). The first sample-and-hold circuit records the increasing saw-tooth voltage until the pulse line (TE) is complete and then holds this. On completion of the period (T) a short control pulse causes the regulator to hold the final generator output and releases the second sample-and-hold circuit which registers the divider output. The generator is then discharged and the process repeated every second period.

Title: Recovery of protein rich paste from krill - by grinding fresh krill to leave some fibrosity, cooking and centrifuging in several stages to remove shell
Inventor: VERNET BOERJE
IPC: A23L17/00
Filed: 1980-10-09
Abstract: Process is for making a foodstuff from a macro plankton knill esp. Euphansidae. First fresh knill is milled in a hammer mill so that the flesh still retains some of its fibrous structure. The resulting mixt. of flesh and shell is sepd. in a centrifuge of the decanter type. The flesh fraction is heated in a heat exchanger to 40-60 deg.C and fed into a holding tank. It is subjected to a further centrifuging after holding at 70-95 deg.C for 1-5 min. This removes excess liq. which is reheated and recycled. Some of the liq. is passed to a different centrifuge before it is discharged. The process provides a useful source of food from the macro plankton Euphasidae from the Antarctic. It gives good sepn. of the fish shell from the flesh.

Patent DE-3047587-A1 (DE)
Inventor: FRIEMERT HORST DIPL ING
IPC: H05K13/02
Filed: 1980-12-17
Abstract: An arrangement for unscrambling ferromagnetic coil springs from a pile of coil springs, and conducting the coil springs to a work station. A cassette containing a disorganized pile of springs is provided with a first surface having openings, and discharge tubes associated therewith. A second surface which adjoins the first surface is provided with impact edges for controlling the upwardly vertical travel of the coil springs in response to a traveling electromagnetic field which, in one embodiment, is produced by a linear motor stator. The linear motor stator is arranged at an angle with respect to the second surface of the cassette, the apex of the acute angle being arranged at the junction between the first and second surfaces of the cassette. The traveling electromagnetic field attracts the springs to the second surface and causes them to travel upwardly until they encounter the impact edges. The inclination of the second surface with respect to the linear motor stator causes the springs to be conveyed into the discharge tubes.
