Patent DE-2606619-A1 (DE)
Title: Rotary filter with rotating cells - having centrifugal discharge of cake
Inventor: MAASSEN HANS
IPC: B01D33/31
Filed: 1976-02-19
Abstract: Rotating filter for suspensions or thick liquor slurries has constantly rotating round the filter cells with continuous discharge of the cake. The main shaft can be rotated constantly or at varying speed. The cake is spun off the individual cells by centrifugal force using high speeds. Each round cell has over the complete filter bag one or more wipers of an elastic material. There is a stationary pressure band against which the cells rotate and against which the cake is pressed. The pressure is adjustable. The cells are rotated at speed under the slurry and in this way serve as agitators. Used for filtering liquid systems of slurries and suspensions. Existing types of rotating filter have problems with difficulty of maintenance and changing the cloth. The filter described overcomes the problems and also avoids the need for separate agitation of the filter bath.

Title: Bitumen processing vat - with film plasticised on periphery of drum revolving in coolant-filled vat, pref. having silicone lining
Inventor: RUEMMER JUERGEN ING GRAD
IPC: C10C3/16
Filed: 1976-12-10
Abstract: Bitumen is processed by cooling the hot liquid bitumen in a thin film until it acquires a plastic state. A revolving drum, open at both face ends, is supported in a cylindrical vat through which a coolant circulates. The bitumen film is applied to the shell of the drum from a container above it. A scraper blade removes the now plastic film after one revolution from the drum. This reduces the cooling time of the bitumen to a min. The vat takes up little space and is of compact design.

Title: Flashlight spectrophotometer for clinical analyses - uses xenon tube and pulse amplitude detector circuit for absorption and attenuated total reflection measurements
Inventor: NOELLER HANS T
IPC: G01N21/25
Filed: 1977-05-13
Abstract: The flashlight photometer comprises a mains powered Xenon flash lamp having an output of 110%/sec and a charging capacitor with a value of 200gammaF. The flash lamp output illuminates the sample in a test cell, e.g. blood, through which it passes and strikes a photo-detector. The pulses from the detector, which are proportional to the absorption of the sample, are amplified and rectified by a transistor. A capacitor is charged up by the transistor to a voltage proportional to the amplitude of the input pulses. The DC level is fed via an impedance-matching FET to an operational amplifier. The output of the amplifier is further amplified in a variable gain amplifier to drive an indicating instrument. The meter can be zeroed when the test cell is empty by means of the final amplifier gain control. The device is suitable for the measurement of bilirubin concentrations in whole blood using both absorption and attenuated-total-reflection spectroscopy.

Title: Turbocharger system for IC engine - has compressor of one turbocharger feeding turbine of second with output fed to intercooler
Inventor: CUTLER JOHN FREDERICK
IPC: F02B37/00
Filed: 1977-06-08
Abstract: The energy of the exhaust gases passing out from the exhaust manifold of the engine is utilised to turn a turbine wheel. The output of turbine wheel is fed to the exhaust system of the vehicle and to any exhaust treating apparatus for eventual discharge to atmosphere. The energy from the turbine wheel used to compress ambient air by a compressor wheel. The air entering the turbine wheel is thus at a higher temp. and higher pressure than that of ambient. after expansion through the turbine wheel the exhaust therefrom is fed, still at relatively high pressure through a line and through the intercooler. Passage of the air through the line results in passage through a first flow path in the second air to air intercooler.

Title: Shut=off valve with sealing member - has flexible membrane whose thickness increases from clamped border to sealing member
Inventor: WURZER LOTHAR DR
IPC: F16K7/16
Filed: 1977-06-22
Abstract: The membrane in a shut-off valve has a curvature(22) which in all positions of the membrane runs over in a curve into the sealing member (15, 17). The material thickness of this curvature (22L, 22R) progressively increases in the direction from the clamping border(12) to the sealing member. This material thickness is approx. twice as great as at the clamping border. The design eliminates stress peaks at the transition from membrane to sealing member.
