Patent DE-2903230-A1 (DE)
Title: Seat belt lock with U=shaped frame - has pressure element releasing locking member before release pushbutton is moved to unlocking position
Inventor: SEEL HOLGER
IPC: A44B11/25
Filed: 1979-01-29
Abstract: The locking member is a steel ball (7) seated in a recess of a pressure element (6) and held in place by projecting part of a locking arm (4). When a push-button (3) is operated for the lock release a stop lug (19) move towards a surface (15), while overcoming resistance of a spring (8). When the two surfaces come against each other, further pressure of the push-button causes the pressure element to slide until a surface (18b) rests against locking element. Continued pressure on the push-button pushes the steel ball of the protruding edge of the locking arm, the steel ball drops into a recess allowing the spring-loaded locking arm to swing, while the protruding edge is a accommodated by the now empty recess on pressure elements (6). Due to the swinging movement of the locking arm catch (21) leaves the opening (20) in a locking plate (2) which is then ejected by a spring (10).

Title: Processing and disinfecting recycle water - esp. for swimming pools, by ozonising with chlorine di:oxide addn. while controlling ozone quantity
Inventor: RUPP CARL-HEINZ DIPL ING
IPC: C02F1/78
Filed: 1979-02-01
Abstract: In processing and disinfecting water, circulating in a closed cycle, by O3-treatment, ClO2 is added as additional disinfectant. The O3 quantity added is limited, so that chlorite, generated from ClO2 oxidn. takes place to a lesser extent. The water can be used in swimming pools, as cooling water or for industrial use. Further oxidn. to chlorate and perchlorate is prevented. After O3 treatment and active C filtration, the water has a high ClO2 content, so that only small ClO2 quantities need be added to maintain the desired ClO2 excess. O3 addn. is also reduced. O3 and Cl O2 act synergetically to achieve a redox potential high above that needed for disinfecting the water. Waste water loading with salts is reduced.

Title: Rotary velocity sensor for marine aerial - has liq. filled sphere as buoyant member in spherical or toroidal container of larger dia.
Inventor: ERNSBERGER KLAUS DIPL ING
IPC: G01C9/06
Filed: 1979-12-22
Abstract: The sensor is intended for both the vertical and rotary velocities for stabilisation and vertical alignment of a marine aerial. It comprises a rotation-symmetrical buoyant body inside a liquid-filled container. A liquid-filled sphere (8) is used as the buoyant body, and the container is also in the form of a hollow sphere (4) or of toroidal shape, of greater diameter. The outer surface of the inner sphere contacts the inner surface of the larger one. The small sphere is of thin-wall structure and has small bores (10). Both spheres may be filled with a liquid of only slightly different specific weight, that in the inner sphere being higher. Typically both spheres are completely filled with liquid. The system provides a high sensitivity for the measured rotary movements, considerably suppression of translatory movement in the frequency range of the ship's motion, and possibly linear angular function in the region of zero position.

Patent DE-3006938-A1 (DE)
Title: Control circuit for rotary field converter - uses phase shifted voltages to control firing pulses for thyristors on machine side
Inventor: BOEHRINGER ANDREAS PROF
IPC: H02P25/024
Filed: 1980-02-25
Abstract: The control system for a rotary field motor converter uses an auxiliary rotary voltage system for the frequency and voltage variable rotary armature voltage system for initiating the firing pulses for the thyristors of the converter on the machine side. This operates at the same frequency as the armature rotary voltage system and its phase position can be shifted relative to it by a control voltage. The zero points for the auxiliary system directly releases the firing pulses for the thyristors without a delay device. The release of further firing pulses following the zero points is blocked until the commutation has been safely connected. The instantaneous voltage of the armature system is formed so that a first signal section for all three phases is cyclically and symmetrically added or subtracted to a further section multiplied by a signal voltage. At least one of the multiplied voltages is now in phase or in phase opposition to the first signal section.

Title: Continuous purificn. of industrial waste gas contg. formaldehyde - by scrubbing with strongly alkaline aq. soln.
Inventor: HIRCHE LUDWIG ING GRAD
IPC: B01D53/72
Filed: 1980-06-20
Abstract: Continuous purificn. of industrial waste gas contg. HCHO involves scrubbing with a strongly alkaline aq. soln. (I), which converts HCHO to formate and methanolate. The formate content of the circulating (I) is kept at 2-20wt.% and pt. of (I) is discharged from the system (dis)continuously. Pref. the gas leaving the first scrubbing zone is scrubbed with a second soln. with a MeOH content kept at 1-15wt.%, whilst the methanolate content of the first soln. is kept at 1.5-20wt.%. In the first stage, the temp. is max. 40 deg. C and the pH of the soln. is 11-12. The spent satn. liquor is added to the first soln. continuously. The process is useful for purifying waste gas from foundries etc. It is cheap and reduces the HCHO content from ca. 500-2000 mg/Nm3 to max. 20 mg/Nm3. The amt. of waste liquor is minimised.
