Title: Continuous BOD determn. - by passing waste water and activated sludge through reactor and measuring change in air oxygen content
Inventor: WIESMANN UDO PROF DR ING
IPC: C02F3/00
Filed: 1979-12-19
Abstract: Continuous determn. of the BOD of waste water is effected by passing a mixt. of the water and activated sludge through a reactor together with air and measuring the difference between the O2 concns. in the air entering and leaving the reactor. The reactor pref. comprises a series of stirrer vessels connected in parallel with a reference reactor, the latter being supplied with activated sludge and air only. The waste water and activated sludge are supplied via metering pumps. Each vessel is equipped with its own gas outlet valve so that the air from each vessel can be supplied to the analysis unit. The amts. of air entering and leaving the reactors can be measured with float-type flow meters. The reactors are pref. thermostatically controlled by a common thermostat. The process can be carried out using relatively simple, transportable equipment; results are obtained continuously with a response time of less than 2 hr, so that the process can be used for monitoring and control of water treatment facilities.

Title: Telephone exchange with memories - uses pointer and group pointer addresses to apply control commands to selectors
Inventor: FRANK REINHARD DIPL ING
IPC: H04Q3/48
Filed: 1980-02-26
Abstract: The telephone exchange stores a group director address in addition to director addresses ensuring the execution of control commands. The group director addresses points in a string of groups to the next address. The addresses perform specified functions according to the devices they address. The advantage lies in monitoring switching events using control commands in a simple manner and in a much shorter time than usual. The control commands are deleted and not the addresses of the devices to which these commands supply.

Title: Automatic guiding system for vehicle - generates command signals from sensor arrangement detecting deviations from reference path
Inventor: TAYLOR CHARLES L
IPC: G05D1/02
Filed: 1980-04-01
Abstract: A guided vehicle has a sensor arrangement to detect side tracking from a reference path continuing at least one straight and one curved section. Command signals are formed according to measured signals provided by the sensor arrangement for the generation of steering and command signals. The latter vary an angular deviation and lateral displacing of the sensor arrangement from the reference path when they correspond to a predetermined function. A steering arrangement controls the direction of travel in dependence upon the command signals. A steering monitor modifies the steering command signals as long as the vehicle travels along the curved section of the reference path. The modification value is essentially the reciprocal of the radius of curvature of the curved section.

Title: Combination measurement device for measuring the mobility in the ankle joint and talocalcaneonavicular joint
Inventor: GRIFKA JOACHIM
IPC: A61B5/11
Filed: 1981-01-02
Abstract: The active and passive mobility of the foot in the ankle joint and talocalcaneonavicular joint is to be exactly measurable with a device which can operate on a purely mechanical basis and is easy to handle. In order to determine the extent of the mobility in the ankle joint an angular rod (2, Fig. 1) is fastened on the calf, and a freely movable angular rail (4, Fig. 1) underneath the foot, whose deflections on movement are precisely shown on a measuring scale. The mobility in the talocalcaneonavicular joint is determined by using special devices which are slid onto the angular rod (4, Fig. 1) and indicate the deflections on movement at the edge of the foot. These comprise a web (9, Fig. 1) which rests against the underside of the line of the ball of the large toe and the ball of the little toe and whose deflections on movement are displayed, in the exemplary embodiment, by a movable scale (15, Fig. 1) and a stationary pointer (21, Fig. 1). Due to its design properties and the general usability for feet of a wide variety of shapes, this device is particularly suitable for establishing the extent of movements and changes in the mobility of the foot, especially for scientific studies, assessments and monitoring of a therapy, as well as for determining and demonstrating foot postures and postural anomalies. <IMAGE>

Title: Mount for optical components
Inventor: MEISTER GERHARD
IPC: G02B7/02
Filed: 1981-04-27
Abstract: The invention relates to a mount for high-performance optical components, which is essentially temperature-invariant with respect to thermal stress between the optical component and the metal of the mount, and in which the coefficient of thermal expansion of the materials of the mount can be selected independently of that of the glass. This is achieved by selecting two materials for configuring the mount which both have a larger or a smaller coefficient of thermal expansion than glass. These combined mounts are dimensioned such that the effect of the radial thermal expansion movement of the two metal rings is to produce a subtractive compensation of the expansive change, and/or to produce a mechanical elastic radial reversal of displacement at one ring of the combined mounting ring. <IMAGE>

Title: Inspection device for the interior of pressure vessels
Inventor: ORTH WOLFGANG DIPL ING
IPC: G02B23/24
Filed: 1981-12-24
Abstract: The invention relates to a device for inspecting the interior of pressure vessels of all sorts, in particular at high pressures and especially high or low temperatures. Because of the low tensile strength of transparent materials at high pressures, the use of windows in the vessel wall is not feasible, and in addition the field of view is often too small or the inspector too far removed from the object of inspection. The object of the invention is achieved when transparent pipes that are joined in a leakproof fashion to the wall of the pressure vessel and whose interior can be accessed from outside the vessel project therein. An optical system which has a corner mirror and through which the vessel interior can be inspected is inserted into the pipe interior. The vessel interior is illuminated through further transparent tubes using lamps or an optical fibre with the aid of the corner mirror. The observation device is suitable for observing measuring equipment, flow processes, chemical reactions, or else for controlling filters, sealing members, stirrers and much else besides in vessels of all sorts filled with gas or liquid.
