Title: Exposure evaluation device for positive photographic originals
IPC: G03B27/73
Filed: 1986-09-16
Abstract: Exposure evaluation device for positive photographic originals is placed under the enlarger for the purpose of subject exposure (33). In addition, the exposure evaluation device can also independently expose coloured sections (37, 38) at the free edges by means of an exposure device consisting of an exposure apparatus (1, 2, 5, 6) and a rotatable filter plate (3) with coloured filter inserts (4). On the layer carrier, marks (19) can also be exposed with the exposure device (9, 10, 11, 12). The encoding marks (19) contain a real value since their distance from the edge of the image varies. When the encoding marks (19) are read out by the sensor (79), the path length is detected by the evaluation unit (60, 61, 62, 63) and assigned to the encoding marks (19). So that each point of the sensor (72) can be detected on the layer carrier, the sensor is located on a cross slide which is driven by the motors (67, 60). The exposure evaluation device can carry out densitometric measurements on the developed layer carrier (53) by means of the search track (31), the section (36) and the subject surface (34). The result serves to perform filter correction for enlargers. <IMAGE>

Patent DE-3641373-A1 (DE)
Title: Knobbed turf stone-laying method
IPC: E01C9/00
Filed: 1986-12-04
Abstract: The patent application relates to a knobbed turf stone-laying method for concrete-paving and interlocking stones, which are laid with gaps in the laid structure so as to produce a turf gap. The turf gap is concreted on already during the production of the stone, as a knob. The knobs provided at certain points on the stones butt against one another during laying (Fig. 1 No. 2) and form a connecting web with a turf gap of 10 to 20 mm. The knobs can butt against one another flat, in conical form or with a convex or concave profile and thus produce an interlocking action. A further variant is a stone with only 2 knobs, which are 10 or 20 mm long and form the turf gap. A further embodiment of the invention is a knobbed turf stone-laying unit. In this case, during production of the stones the formwork dividing wall is recessed and the knobs are concreted on as connecting webs. At the connecting web 3, the knobbed turf stone-laying unit can have a notch, in order that the connecting web tears upon shaking off and the stones again lie individually in the area. <IMAGE>

Patent DE-3713562-A1 (DE)
Title: Method for determining the position of control elements with inductive position encoders
Inventor: SCHMITZ ECKEHARD
IPC: G01B7/00
Filed: 1987-04-23
Abstract: In such methods, the inductive position encoder consists of one or more electrical coils, in which an armature is displaceable as a result of which the position of opening of a valve body can be provided electrically as analog output signal for an evaluating device. Component tolerances can have the result that the relative position between the armature and the coil or coils is different for each encoder produced. The novel method therefore provides: that when the control element is taken into operation, the control element or the position encoder or both is/are aligned in that the control element is brought into a predetermined alignment position (HM) which is different from the final position (h0) and the position encoder is aligned with regard to its measuring distance in such a manner that the alignment measurement value (UAM) obtained during this process assumes a predetermined quantity and during the subsequent operation of the control element, the actual measurement value (UA) is correlated with a particular position (H) of the control element in that the difference between the actual electrical measurement value (UA) and the zero-point electrical measurement value (U0) is divided by the difference between the alignment measurement value (UAM) and the zero-point measurement value (U0). This makes it possible to use only few accurate components and carry out simple alignment.

Title: Device for hydroextraction of tubular fabric
Inventor: JACOBSSON BERTIL
IPC: D06B15/02
Filed: 1988-02-22
Abstract: In such devices, the tubular fabric is conveyed vertically upwards behind the press-roller pair, at the same time guided via the stretcher and subsequently brought transversely or downwards to the folding element. The device is thus tall. The stitch orientation in the tubular fabric is changed in an undesirable manner behind the stretcher. The new device is to ensure in a constructionally simple manner that the original stitch orientation of the tubular fabric is completely re-established. In order to arrive at a low construction of the device (1) and in order no longer to influence the original stitch orientation which is re-established in the stretcher, the stretcher (10) is arranged lying approximately horizontally, bridging at least to a great extent the lateral spacing (A) between the press-roller pair (8) and the folding element (1). The stretcher (10) functions as it were as a protective conveying device for the tubular fabric (F) to the folding element (11), as a result of which the original stitch orientation re-established in the stretcher is no longer distorted. As a result of the high quality of the folded tubular fabric and of the simple construction, the device is suitable for hydroextraction of superior tubular fabric with a high throughput rate. <IMAGE>

Patent DE-3837831-A1 (DE)
Title: Substrate with hydrostatic pressure compensation for a pressure point massaging device
Inventor: AUGUSTIN HANS-ULRICH
IPC: A61H7/00
Filed: 1988-11-08
Abstract: A substrate with hydrostatic pressure compensation (1) for a pressure point massaging device (3) has a liquid-filled or gas-filled uni- or multi-chamber system (2) over which the pressure point massaging device is located. This can be designed, for example, as a mat whose structure causes mechanical pressure stimuli for a pressure point massage at the support surfaces on walking over it barefooted or on lying on it. As a result of the pressure compensation inside the substrate its surface adapts itself to the shape of the object or body part lying on it. This not only increases the support surface, but also generates the same counter-pressure everywhere inside the contact surface. This pressure can be transmitted via mechanical components, for example beads or stamps onto the body surface to be massaged. Use of a substrate with hydrostatic pressure compensation permits pressure point massages on round surfaces, for example foot reflex zone massages on hollow feet or treatment of hunch back. <IMAGE>
