Abstract:
The invention is an inverted microscope with a housing having multiple integrated ray paths leading from the specimen being examined to (a) the viewer/operator and (b) one or more auxiliary ports used for image recording and/or measurement by accessories such as cameras and video recorders. The microscope lens is positioned below the specimen stage; and, positioned below the lens, is a simple reflector which deflects the combined rays from the lens diagonally upward toward the viewer at exactly the same angle at which the viewer looks into the microscope's binocular eyepieces. The position of this simple reflector is the lowest point in the unit's paths of rays, thereby significantly lowering the lens turret and, therefore, the specimen stage to a relatively low, ergonomically-appropriate position. The optical arrangement is simple and compact, minimizing the number of deflections in the path of the viewing rays. Further, light from the microscope lens is deflected along the second path to the auxiliary port and the recording camera by an optical element which is positioned above the reflector in the diagonally-upward path of rays, thereby providing ample room at the auxiliary port to permit use of a recording camera having an automatic-rewind housing. The invention also includes removable and interchangeable tubes which include viewing binoculars and/or an additional auxiliary image port positioned along a vertical path of rays and/or a further additional auxiliary image port positioned along a horizontal path of rays.

Abstract:
The invention relates to a system unit for desorbing carbon dioxide and other impurities from highly pressurized methanol. Said system unit comprises at least one or more expansion vessels arranged in succession, at least one heat exchanger, and at least one liquid/gas separator. The inventive system unit contains: a) a line (1) through which the intensely cooled methanol leaving expansion vessel (C) is introduced into the heat exchanger (E) from underneath, and; b) a line (2), though which the heated methanol is drawn out of the heat exchanger (E) from the top, and which serves to connect said heat exchanger to a liquid/gas separator inside of which the remaining carbon dioxide still contained in the methanol is desorbed and separated out to the greatest possible extent. This system unit enables the cold due to evaporation, said cold resulting during the desorption of carbon dioxide, to be obtained inside a heat exchanger and constitutes an important cold energy source for carrying out absorption.
Abstract:
In a vehicle brake having a brake piston accommodated in a housing, a blocking device for securing the brake piston inside the housing and an actuating device for controlling the blocking device, it is provided that the brake piston together with the housing delimits a fluid chamber, which is chargeable with hydraulic fluid, so that the brake piston for actuating the vehicle brake is displaceable hydraulically inside the housing along a piston longitudinal axis, that moreover the blocking device comprises a ramp arrangement and a blocking element that is displaceable relative to the housing, and that by means of the actuating device the blocking element in interaction with the ramp arrangement for securing the brake piston inside the housing is displaceable and connectable to the brake piston. In this vehicle brake, it is further provided that the actuating device comprises a motor drive, which is drive-connected to the ramp arrangement, wherein the blocking element upon activation of the motor drive is displaced to secure and release the brake piston inside the housing.
Abstract:
A shaft (34) is supported in the bottom (22) of a casing (20) and is rotatable for mechanical brake application. A ramp assembly (40) which is fixed to the casing and designed as an annular plate is supported on the bottom (22) around the shaft (34) and prevented from rotating by an off-center twist stop (42), and it is centered in the casing (20) in a way bypassing the shaft (34). Moreover, a rotatable ramp assembly (50) is arranged inside the casing (20) so as to be axially displaceable and is connected to the shaft (34) for torque transmission. The rotatable ramp assembly (50) is supported in such manner on the ramp assembly (40) which is fixed to the casing that it converts torque applied to it by the shaft (34) into an axial actuating force (B).
Abstract:
A methanol/water scrubbing solution containing colloidal metal sulfides formed from metal carbonyls and resulting from the scrubbing of industrial gases, such as synthesis gas, is subjected to agglomeration of the metal sulfides before the scrubbing solution to be separated enters the separating column which separates the methanol from the water containing precipitated metal sulfides. The agglomeration is carried out in a precipitation vessel and the scrubbing liquid is diluted before it enters the precipitation vessel. The result is minimal encrustation of the trays or other parts of the cleaning plant for the scrubbing solution.

Abstract:
A one-piece casing (20) comprising a bottom (22) and a shell (24) formed with a cylindrical bore (26) houses a piston (30) for hydraulic actuation of a brake. For mechanical parking brake actuation, a shaft (34) is supported in the bottom (22) of the casing and a ramp arrangement (50) is rotatable by the shaft, thereby being displaceable axially away from a ramp arrangement (40) which is secured to the casing. Two strut members (60,64) which are screwed together constitute an adjustable strut between the axially adjustable ramp arrangement (50) and the piston (30). A return spring (90) is positioned under axial bias between a thrust bearing (92) secured to the casing and a thrust bearing (58) at one of the two strut members (60). The thrust bearing (92) which is secured to the casing is formed at an insert (84) by which one of the strut members (60) is guided non-rotatably. The ramp arrangement (40) which is secured to the casing as well as the insert (84) are retained against axial displacement in the casing (20) by a common fastening member (96) and are prevented from rotating by a common twist preventing element (42).
