An illumination device for microscopes is detachably connected to the microscope and has at least one unconventional illumination source such as an LED, laser or the like. The microscope has an operating control for adjusting the brightness of the illumination, and the brightness of the unconventional illumination source is adjusted by means of this operating control.

A platen of an injection molding machine includes a plate-shaped center area having corners, each corner formed with a recess. A plurality of sleeves is received in the recesses of the center area and defines bores for accommodation of column-like holding and/or guide elements. The sleeves have an outer surface in confronting relationship to the center area and are configured for only partial connection to the center area, thereby establishing an elastic connection between the center area and the sleeves.

The invention relates to a cleaning agent, particularly for cleaning sewers, for fat and/or protein-containing sewage from the home or having a municipal or industrial origin, with a content of urea, a urea derivative, a urea salt and/or a urea derivative salt, the cleaning agent containing approximately 50 to 90 wt. % urea, urea derivative, urea salt and/or urea derivative salt, based on dry substance, and an alkaline-acting agent, protease and fat-degrading microorganisms.
摘要:
A mold mounting plate for an injection molding machine for processing material, in particular plastic material, includes a main body having a plate-shaped central portion. Received in the main body are plural sleeves which define openings for support of column-like holding and/or guiding elements of the injection molding machine, and are secured to the central portion such as to establish a flexible bending/torsion joint. In this way, a transmission of moments onto the column-like holding and/or guiding elements as a result of a deformation of the mold mounting plate is minimized.

A closing unit for an injection molding machine for processing plastic material includes a fixed mold mounting plate connected to a moveable mold mounting plate by means of a crank or toggle lever mechanism, which is operated by at least two motor-driven spindles arranged in series and having thread pitches in an opposite manner. One spindle is operatively connected to the fixed mounting plate, whereas the other spindle is connected to the crank or toggle lever mechanism. A sleeve-like force transmission element is arranged concentrically in relation to the spindles. Spindle nuts are respectively provided on opposite end faces of the force transmission element and interact with the power transmission element and the spindles.

An agitator includes a drive motor having a shaft projecting through an axial end of a housing and having connected thereto a propeller boss. The propeller boss and housing define a circumferential gap spanned by a circumferentially extending radially outermost gap covering and sealing portion of a deflector ring. The deflector ring includes a radially innermost ring mounting portion located in the circumferential gap. The deflector ring is preferably made of elastomeric material and an outermost circumferential surface of the deflector ring is exteriorly convexly curved in the form of an aerofoil converging axially toward ends of sealing lips of the deflector ring gap covering and sealing portion.

The method is for non-erasable or non-alterable storage of data records in a device, initialization establishing the format of the data records and determining those data fields by way of which summation is permissible. An initialization character sequence is transmitted that has at least a number and length of the data fields to be stored. The valid initialization character sequence is accepted and executed only once. After acceptance only data records whose coding satisfies the information is accepted.
摘要:
A device for transferring load carriers between conveyor paths arranged at an angle relative to one another. The device has at least one guide element which is movable by a drive in the transporting path of the load carriers on a first conveyor path and in the direction of a second conveyor path for transferring the load carriers into the second conveyor path. In order to enable a reliable transfer of the load carriers and a high transfer capacity at the same time, the guide element is constructed as a driver which can move into a recess in the load carrier in a positive-locking manner for the transfer process.
摘要:
A transporting system including, guide rails which laterally define a travel path that has branches, a floor conveyor vehicle which is guided by the guide rails and has two longitudinal sides, a pair of guide rollers which are arranged at each of the longitudinal sides of the vehicle so as to engage with the guide rails at least on one side, the pair of guide rollers including inner and outer guide rollers. A switching mechanism is provided for changing the travel path within a branch. The switching mechanism being arranged at the vehicle and including a swivel drive for the outer guide rollers of the pair of guide rollers. The outer guide rollers are supported on the vehicle so as to be swivelable between a guidance position, in which the inner and outer guide rollers engage with the guide rail, and an open position in which the outer guide rollers release the guide rail.
