Title: Solid and liq. separator uses filtering and magnetic effects - which are combined on endless filtering belt or drum
Inventor: WEGNER HORST
IPC: B03C1/02
Filed: 1980-10-01
Abstract: Appts.for sepg. liq-solids mixts. contg. magnetisable particles combines filtering with magnetic separation. The magnetic system is immediately adjacent to the mechanical or filtering sepg. system. Pref. an ascending endless filter belt receives a feed of liq. contg. magnetisable particles discharged onto the belt immediately above the underlying magnets, which may be permanent or electro magnets. The magnetisable particles are thus immediately drawn onto the belt, and ascend together with a proportion of the liq. to pass over a suction chamber where the residual liq. is extracted from the particles. Applicn. includes the sepn. of magnetite and ferrosilicon suspensions from the chemical industry or process water from steel rolling mills. The arrangement enables maximum advantage to be developed from the magnetic system itself by close contact with the separation surface and, due to the arrangement shown, also disposes of the majority of the liq. by simple gravity , leaving only a smaller proportion to be extracted through the vacuum filter.

Title: Control drive for aircraft rudder - temporarily substitutes integrated signal for running speed of positioning motor for direct measuring of rudder position
Inventor: HOFMANN FRITZ DIPL ING
IPC: G05D3/14
Filed: 1980-10-04
Abstract: The signal of an actual value generator directly measuring the rudder position and the signal of a generator measuring the running speed of the positioning motor are fed back during regulation of the drive positioning motor. The signal for the running speed of the positioning motor is temporarily integrated in the regulator for a short time. It is substituted for the direct measurement of the rudder position. This temporary integration can be achieved through a delay element of a first order. This delay element can be an operational amplifier (14). The latter (14) can also serve as the temporary suppressor of the direct measuring signal. The positioning motor's (10) shaft (12) has a tachogenerator (11). The setting component for the ruder (20) is coupled without play to a potentiometer (21).

Title: Method and device for the stereoscopic reproduction of television pictures with normal transmission bandwidth
Inventor: COLLENDER ROBERT BRUCE
IPC: H04N13/221
Filed: 1981-03-30
Abstract: The present invention relates to stereoscopic television, using a relative movement between camera and scene, in which no aids are required at the eye of the viewer. The present invention generates a hologram-like scene reproduction three-dimensionally and with full movement for viewers arranged distributed over a wide angle and operates with normal television broadcast signals without there having been the need to change the studio equipment or the domestic television antenna. The only change at the receiving end is a special television image projector. The system is compatible with stored standard television signals. The cathode ray picture tube is omitted and is replaced by an array of CCD liquid-crystal light valves which accept the television fields in parallel from a memory and are arranged to form an arc of a circle for scanning. The replay array accepts a displaceable sequence of successive television frames which are used as the basis for the horizontal sight parallax of the 3-D representation. The light valves reflect polarised light, the degree of polarisation being a function of the brightness of the scene. The array is optically scanned and the image sequence is projected rapidly on a cylindrical concave semireflective screen which projects the entire light onto a rapidly moving vertical outlet slot of light, through which the viewers can see the reconstructed 3-D scene. <IMAGE>
