This is a simple, low-cost filter which requires little maintenance.
Patent DE-2803804-A1 (DE)
Title: Whitening de-inked waste paper for graphic paper prodn. - by recycling all chemicals and adding usual amt. of bleach and de-inking chemicals
Inventor: SCHLEGEL MANHART DR ING
IPC: D21C5/02
Filed: 1978-01-28
Abstract: Increasing the degree of whiteness of deinked waste paper is carried out by pulping in a mixer at a 2-3 fold concn. of all bleach and deinking chemicals, which is attained by the limiting concn. on re-use of the return water in close recirculation from the subsequent dehydrated waste paper and the fresh addn. of the usual chemicals per charge. The deinked waste paper from newspapers and periodicals can be used instead of prim. wood and cellulose pulp in graphic papers. Besides better utilisation of the H2O2 bleach, the deinking effect is higher and mottling is suppressed. In an example, deinked pulp with a degree of whiteness of 65.2% was obtd. from dispersed wate paper with a degree of whiteness of 43% by recycling and adding fresh liquor, so that the concn. of chemicals was 2-3 times te usual concn. Graphic paper with a degree of whiteness of 68% and good printing qualities was obtd. by adding kaolin filler.

Patent DE-2829104-A1 (DE)
Inventor: FLOEGEL EBERHARD
IPC: F16H61/56
Filed: 1978-07-03
Abstract: The hydrodynamic torque converter comprises pivoting blades (9) made of plastic material and arranged up-side of a zone, particularly a fixed wheel. The blades can pivot around an axis (11) so as to be brought, by the liquid current, to take the same direction as the current. Each of the pivoting blades is placed between two adjacent fixed blades (10) in such a manner that its pivoting angle is limited by both the directions of these two fixed blades (10). Under certain operating conditions of the converter, this pivoting angle limitation causes the blades to form an angle with the direction of the liquid current. The elastic material of the blades gives way to the liquid pressure, in other words the blades deform and direct their edges in the direction of the current. By making a judicious choice of the parameters, the losses can be reduced to a minimum.

Title: Blood pressure monitor using arterial tonometer method - has two piezoelectric sensors monitoring artery expansion and compensating for movement of patient
Inventor: PIFFL ERNST
IPC: G01L9/00
Filed: 1978-11-07
Abstract: The blood pressure monitor employs a cuff with two piezoelectric sensors, that are pressed firmly against the skin where the artery runs under the latter. One of the sensors displays the variable expansion of the artery, while the other sensor, which is coupled in electrical opposition, provides a signal for compensating the movement of the patient. The two sensors are supported by mechanically separate membranes, e.g. thin metal plates, each conductively connected to a surrounding stable metal frame. Each sensor comprises a piezo-oxide chip, one with its negative pole attached to its membrane and the other with its positive pole attached to its membrane. Each chip has a soldered contact for a signal lead. The cuff is pref. filled with air to force the sensors into contact with the skin, or alternatively the sensor may be attached to a wrist band similar to a watch strap.
Patent DE-2848675-A1 (DE)
Inventor: VERMOT MICHEL
IPC: G04G13/02
Filed: 1978-11-09
Abstract: An electronic timepiece with an alarm device, having a digital display unit for indication of the actual time and a memorized time of alarm, and an analog display unit driven by a stepping motor. In such a timepiece, the alarm signal is produced from signals delivered by the frequency divider and is transmitted to an electroacoustic transducer when coincidence exists between the time as measured by the timepiece and the memorized time of alarm. During the signal, the consumption of current is relatively high and is further increased when a driving pulse of the stepping motor is superimposed upon the alarm signal. Such a peak of current is undesirable because the magnetic field produced by the excitation coil of the electroacoustic transducer may disturb the correct functioning of the motor. A solution to this problem is to shift the alarm pulses in time with respect to the driving pulses so that they never appear simultaneously. To this end, the timepiece includes an electronic circuit which is enabled by an alarm logic circuit, and which receives signals from the frequency divider for delivering an alarm signal, at the time of alarm, such that the alarm signal is shifted in time with respect to the driving pulses of the stepping motor.
