Title: Devices for the contactless one- and three-dimensional measurement of jaw or jaw joint movements
Inventor: KLETT ROLF DR DR
IPC: A61B5/11
Filed: 1981-07-08
Abstract: The invention relates to a device for the contactless one- to three-dimensional measurement of jaw or jaw joint movements with the aid of measuring devices which have optoelectronic signal transmitters and signal receivers between which light signals are transmitted directly or via a reflector belonging to the measuring device. A part of the measuring device is placed on the lower jaw of a patient. In accordance with one embodiment, the signal transmitter emits a light beam which impinges on a light-sensitive signal receiver which has one- or two-axis positional sensitivity transverse to the direction of impingement of the light beam, with the result that the output signal of the signal receiver depends on the relative displacement between the signal transmitter and signal receiver transverse to the direction of impingement of the light beam. In a further embodiment, each signal transmitter, which is connected only to the upper jaw or lower jaw, emits a light beam which impinges on a reflecting or transparent grid which moves relative to the signal transmitter, with the result that the number of light pulses reflected or transmitted by the grid depends on the relative displacement of the respective signal transmitter with respect to the associated grid transverse to the direction of impingement of the light beam (incremental path measurement).

Patent DE-3144092-A1 (DE)
Title: Method for the protection or scour protection of natural soils, artificial fillings and systems as well as underwater structures on the basis of Colcrete mats or filled fabric mats
Inventor: STEIN DIETRICH DR ING
IPC: E02B3/12
Filed: 1981-11-06
Abstract: This patent application describes a method which enables rolled-out fabric mats, lying on a solid base or just above or below the water surface, to be filled in a controlled manner with Colcrete or thixotropic or colloidal materials and enables this system to be installed without diver assistance at any location under water. This is made possible by the interlacing at the works of stronger textile threads in the longitudinal and transverse direction of the mat in certain areas, which serve as primary suspension. Acting on these primary suspensions is the secondary suspension, which forms the connection between the mat and the release mechanism of a lowering frame. In large construction projects, the lowering frame can be a component of a floating working platform in which all mechanical units for the spreading, filling and lowering operation of the fabric mats are integrated. The method enables underwater structures such as pipelines, foundation bodies of offshore platforms, etc. to be protected from mechanical stresses and scouring irrespective of the depth of water and also largely from the flow conditions.

Patent DE-3230058-A1 (DE)
Title: Method and device for circulating the heat carrier in a radiator system
Inventor: KLAUSECKER KARL
IPC: F24D19/10
Filed: 1982-08-12
Abstract: The circulating pump of a radiator system is operated at a speed which is dependent on the heating power in order to avoid consuming unnecessary energy when the radiators are turned down. The pump drive contains a converter which is supplied from the supply network and has a pulse-controlled invertor supplying an asynchronous machine. A constant, frequency-independent binary curve shape which is pulse-width modulated with a high-frequency sampling voltage is specified for the pulse-controlled invertor output voltage. In the case of the selected curve shapes (Fig. 3), the harmonics which are caused by the binary curve shape are in a region where they have no significant influence either on the losses in the invertor and the machine which are caused by harmonics or on the development of noise in the radiator system. A sampling frequency of over 5 kHz is required for the pulse-width modulation, which is possible as a result of the use of power transistors as the invertor switches. <IMAGE>

Title: Process for the elimination of ammonia from biochemically pretreated industrial waste water
Inventor: ZUELKE HANS-JUERGEN DIPL BIOL
IPC: C01C1/08
Filed: 1983-03-14
Abstract: The invention relates to a process for eliminating ammonia from biochemically prepurified waste water, such as is produced, for example, in plants for thermal processing of coal. The aim of the invention is a process for the substantial elimination of ammonia from waste water (up to residual concentrations < 100 mg/l), without lime or other chemicals having to be added and the solids present having to be eliminated. The essence of the invention is that the treatment of the solid-laden waste water is carried out in the sequence     - biochemical pretreatment   - thermal expulsion of ammonia   - biological secondary purification, where the solids loading is to be up to 5 g/l of waste water and the residual ammonia concentration is to be < 100 mg/l. According to the invention, this is achieved in that the outlets of the biochemical pretreatment, without separation of biomass, are transferred into a stripping column and are deammoniated by thermal treatment, specially designed packings being used, which prevent a deposition of solids because of their geometrical form and surface property. Areas of application are all those where the object exists of eliminating thermally expellable ammonia from solids-laden biochemically pretreated waters.
