Title: System of rear-view mirrors for cars
Inventor: FOERSTER HANS-JOACHIM PROF DR
IPC: B60R1/06
Filed: 1986-07-03
Abstract: In the case of a system of rear-view mirrors for cars, an outside rear-view mirror is mounted in the window region of the door at least on the driver's side. The said mirror is situated in front of the point of sight of the driver, in relation to the longitudinal direction of the vehicle, but at approximately the level of the point of sight, so that the driver has to turn his head outwards to look into the wing mirror. This results in an extension of the field of view to the rear on the driver's side and an extension of the field of vision which can be included using the wing mirror, so that the area not included in the field of vision is reduced and so it is not considered to present a danger in normal driving conditions.

Title: Tensioning-roller arrangement on a belt drive
Inventor: FISCHER ADOLF
IPC: F16H7/12
Filed: 1986-10-31
Abstract: A tensioning roller of a belt drive is fastened to a lever arm which can be pivoted about an axis and on which there engages, furthermore, a bending/compression spring which applies the required belt-tensioning force. An increased belt-tensioning force due to thermal expansion within the belt drive is reduced by pivoting the lever arm until an equilibrium of forces has been established at the lever arm between the force of the bending/compression spring and the belt-tensioning force on the tensioning roller. The bending/compression spring is advantageously produced from bimetal.

Title: Method and apparatus for the production of wood laminate shapes with small-radius curves (small-radius arcs) and curved shapes (arc shapes) by producing flexibility, bending and bonding of wood lamellae
Inventor: KLINGLER HELMUT
IPC: B27M3/00
Filed: 1986-12-03
Abstract: In the method for the production of wood laminate shapes with small-radius curves (small-radius arcs) and curved shapes (arc shapes) by producing flexibility, bending and bonding of wood lamellae, the flexibility is produced by coupling electric heating and steam throughflow in hoods at a temperature lying around or above the water evaporating point, to prevent condensate formation and to obtain a wood dampness which can be used for the bonding. The bending, bonding and pressing takes place within the temporarily limited flexibility after the steaming, by apparatus and arrangement. The bending and pressing is produced between tough, resilient rails by means of tensile stress and bending pressure through arms in the convex region, and by means of compressive stress in the concave region, in order to obtain a closed-joint and radial bending development via an inner mould. The bending and pressing apparatus comprises bending arms and webs or plates, into which the lamellae, which have been previously bonded by bonding rollers, are inserted in bundles and guided during the bending process. Rope tension brings about, in the convex bending region, the pressing against the inner mould. Pressure-limiting templates limit the rope pressure and prevent deformation of the curves. The leg pressing takes place by means of pressure beams, the anchored bending arms serving as thrust bearings. The adjustable clamping of the units on the frame of the apparatus allows the production of many different shapes, which... Original abstract incomplete.

Title: Device for nondestructive image production and position-selective surface treatment in focused ion beam systems
Inventor: BETZ HANS DR ING
IPC: H01J37/30
Filed: 1987-02-17
Abstract: In the case of a device for nondestructive image production and position-selective surface treatment in focused ion beam systems, having an ion source which contains a plurality of types of atoms, but at least one light type of atom and one heavy type of atom, which are used individually depending on the application with the aid of a mass separator, a focused ion beam is produced using the multi-atom ion source and its light atom, which ion beam is passed over the surface of the test item in such a manner that a secondary electron signal is produced at each point on the surface, which secondary electron signal is recorded as a function of the beam position and produces an image of the surface, as a result of which an unambiguous pixel allocation to the surface of the test item is ensured, so that the same beam position and thus the same ion-optic arrangement can be used selectively for the heavy atom, which is required for processing the surface, of the ion source.
Patent DE-3705718-A1 (DE)
Title: Measuring device and method of determining the circumference of extremities in any postural position
Inventor: FISCHBACH JOERN-UWE PROF DR RE
IPC: A61B5/107
Filed: 1987-02-23
Abstract: The device and the method permit free guidance of the measuring frame, operating with light barriers, over an extremity in virtually any postural position during measurements of the circumference, e.g. of swollen extremities, for fitting of support stockings. Moreover, a tilt angle that is not excessively large between the axis of the extremity and the normal to the plane of measurement introduces no error into the measurement of the circumference. To this end, rows of light barriers 4 and 5 are used to determine the positions of the shadow boundaries defined by the extremity on two closely adjacent planes of measurement in two directions perpendicular to one another. The arithmetic mean of the latter serves to calculate the tilt angle and hence to correct the circumference of the extremity. <IMAGE>

Patent DE-3714979-A1 (DE)
Title: Antenna arrangement
Inventor: CZERNETZKI HANS PETER
IPC: H01Q13/10
Filed: 1987-05-06
Abstract: An antenna arrangement having a closed, rectangular metal frame and at least one antenna conductor running in the frame opening, parallel to one frame edge. The invention is based on the object of designing this antenna arrangement such that particularly matched transmission or reception operation is made possible. The object is achieved in that the antenna conductor (12, 17) runs parallel to one of the longer frame edges (10a, 18b) and is electrically connected in DC terms to the metal frame (10, 18), and in that the length of the antenna conductor (12, 17) and its distance from the adjacent frame edge (10a, 18b) are selected such that optimum (resonant) matching is produced for waves which are polarised transversely with respect to the longitudinal extent of the metal frame (10, 18). The invention makes use of the effect that the window frame acts as a slot antenna. This results in the advantage that vertically polarised waves can be received using an antenna arrangement whose extent is greater in the horizontal direction than in the vertical direction. This can be implemented in the region of the windscreens of all normal passenger vehicles. <IMAGE>

Title: Device for the contactless scanning of a surface
IPC: G01B11/30
Filed: 1987-05-20
Abstract: The invention relates to a novel beam guidance in optical profilometers and ranging sensors (range finders) which measure in a contactless manner. After reflection at the surface, the scanning beam is immediately retroreflected into itself once again by a double-pass beam guide and passes for a second time over the surface. After the second reflection, the beam axis again runs back to the sensor in an antiparallel fashion relative to the direction of incidence. As a result, local profile gradients are compensated and faulty measurements and outliers in the measurement are prevented.
