Patent EP-0484711-A1 (EP)
Inventor: VOSS KLAUS-DIETER DIPL-ING
IPC: B29C48/08
Filed: 1991-10-17
Abstract: A flat sheet die for an extruder comprises an upper die part and a lower die part having elongated die lips (2, 4) which delimit the outlet gap at the top and bottom. At least one of the two die lips (2, 4) is of a flexible design in its front region due to a reduction in its thickness. Adjusting bolts (3), which deform the die lip with a bending line corresponding to the amount of their adjustment, are supported on this front region at a distance from each other and are secured to abutments fixed on the die. In order to permit the production of flat sheets with thickness deviations from a predetermined average thickness lying within desired tolerance limits, adjusting bolts (3) are provided in the region of their support on the flexible region of the die lip with a head (5) which is a poor conductor of heat and/or with a layer of heat-insulating material. <IMAGE>

Abstract: A piston-cylinder unit for producing and transmitting compressive forces onto adjusting elements which are guided so as to be slidable on a straight line. The piston-cylinder unit includes a push rod mounted so as to be capable of oscillating transversely of the direction of the compressive forces in a unilaterally open skirt-type piston. The push rod is slidingly movable from a centered position into an oscillating position. The centered position is determined by sealing members placed so as to face each other and mounted at an outer periphery of the push rod and an inner rim of the skirt-type piston. The push rod is movable into the skirt-type piston toward a fixed stop arranged in the skirt-type piston. The push rod is movable against the force of a spring element arranged at the bottom of the skirt-type piston.

Abstract: A camera (1) comprising a solid-state image sensor (2) has a shutter device (7) which comprises a main shutter blade (9) and an auxiliary shutter blade (10) secured to one and the same shaft (11), which blades (9, 10) are rotatable through a radiation path (5) towards a pick-up area (16) of the image sensor (2) to be exposed. By securing the main shutter blade (9) and the auxiliary shutter blade (10) at a small angle with respect to each other to one and the same shaft (11) it is achieved that notably in the case of short exposure periods increasing relative differences in the extent of exposure between parts of the pick-up area (16) are limited so that a reduced location-dependent exposure of the parts is realised. 
     The auxiliary shutter blade (10) is preferably small and/or transparent. An optionally gradual extent of transparency of the auxiliary shutter blade achieves, independent of the apertures of lenses to be arranged in the radiation path, a gradual variation of the exposure when shifting the initial instant of the exposure period.

Abstract: A robotic arm 1 moves a cranked spoon 2 under control of a control unit 3 to scoop food from a dish 6 and transfer it to an eating position E adjacent to the mouth of a user. A display screen 4 has a series of columns representing adjacent strips of the dish, and the control unit 3 moves a cursor to each of the columns in turn. A switch 5 enables a user to select the column concurrently associated with the cursor and the control unit 3 then moves the arm 1 to remove a scoop of food from the corresponding area of the dish and transfer it to the eating position. The columns are further divided into segments and the arm removes food from each of the segments in turn, always starting at the same position in each column. Instead of a display screen a box carrying a series of sequentially illuminated lamps can be placed adjacent to the dish, and the switch can be operated to select the appropriate strip in similar manner.

Abstract: A bipolar or field-effect transistor amplifier (4) with very large dynamic range for use as a preamplifier in a radio receiver, optical link receiver, or the like. The amount of gain is approximately an integral number. Diode-connected transistors (16₁ ··· 16 N ) in the collector load circuitry of a gain-providing transistor (13) cancel the distortion from the non-linear effects of the emitter-base junction of the gain-providing transistor at high input signal levels. The number of diodes corresponds to the amount of gain desired. To reduce the noise generated by the amplifier, the emitter of the gain-providing transistor has an inductor (15) in series therewith and the collector load circuitry has an inductor ( 17) therein, the ratio of the inductances substantially determining the gain of the amplifier.

Abstract: A filter aid material and a method for using same in a filtration system for reclaiming and maintaining coolant oil used in aluminum rolling or working processes are disclosed. The filter aid is a fibrous material which is permeated with an acid material and may be provided in either particulate form as a body feed or as a compressed filter pad. As contaminated oil flows through the filter aid, the acid acts chemically to remove aluminum fines and oxides as well as the aluminum portion of contaminating soap in the coolant oil. Use of the filter aid with acid greatly reduces the amount of conventional filter aid previously used and produces a relatively small amount of residual filter aid which can be disposed of by incineration.
