Patent DE-3616866-A1 (DE)
Title: Self-aligning bonding process for ball bearings
Inventor: HABERLAND RUEDIGER PROF DR ING
IPC: F16C23/00
Filed: 1986-05-20
Abstract: The self-aligning bonding process according to the invention for ball bearings makes it possible for the first time to bond ball bearings onto shafts or into holes in housings, even in the case of large bonding gaps, such as, for example, 50  mu m, the process being such that the bearing races lie concentrically and at right angles to the axis of rotation of the shaft or to the axis of the housing. In contrast to the previous, static bonding processes, where no alignment is possible, the parts to be joined are, in this new process, moved and aligned relative to one another while the adhesive is curing. The self-alignment of the parts to be joined (e.g. the inner race of a bearing to a shaft) is accomplished by means of a force acting radially on the bonded joint and circumferentially relative to the joint, this force acting until the curing of the adhesive is complete and being achieved either by means of a non-rotating force and rotating parts to be joined or by means of a rotating force and non-rotating parts to be joined or by rotation of the force and the parts to be joined in opposite directions or by rotation of the force and the parts to be joined in the same direction but at different speeds.

Patent DE-3632290-A1 (DE)
Title: Drive for sectional doors
Inventor: ALTROGGE WILHELM E DR ING
IPC: E05F15/686
Filed: 1986-09-23
Abstract: The invention relates to a drive for sectional doors, the geared motor of which is arranged on the inside of the door, preferably on the door top edge. The driving rope located under the garage ceiling exerts a pull component for opening/closing the door in the horizontal. However, the rope ends lead to driving pulleys on the door shaft mounted on the lintel, for the purpose of compensating the weight of the door. In this way, the motor generates on the door top edge, by means of its driving rope, an additional torsional force which has a favourable effect on the vertical door movement. The individual sections of the door roll through the curve of the running rail, without being jammed. The diameter of the rope pulley, driven by the motor, on the shaft located on the lintel can be varied. For an easy starting of the opening door, it is increased, in order to exert the highest possible torsional moment. The pivoting arm on the drive housing for the deflection of the closing rope serves for compensation in relation to force components directed towards the garage ceiling, in particular for the last phase of closing of the sectional door. The abrupt inclination of the arm is utilised to stop the motor by means of an inclination switch.

Title: Method of measuring the sensitivity of the cornea of the eye
Inventor: BIERMANN HANS DR
IPC: A61B5/103
Filed: 1986-10-11
Abstract: Measurement of the sensitivity of the cornea of the eye is performed with a plastic measuring thread using electrical current that is preferably applied in square wave voltage to defined sites on the cornea. The current or voltage is increased until the patient responds either by reflex closing of the lids or by stating that he/she feels the current, whereupon the voltage can be read off on a voltmeter. By using extremely thin, very soft electrodes, measurement of the sensitivity of the cornea is possible in a manner that is virtually free of any mechanical components or differences in manipulation.

Patent DE-3639969-A1 (DE)
Title: Bearing arrangement of a displacer in a displacement chamber
Inventor: MAIER HANS PAUL
IPC: F01C1/04
Filed: 1986-11-22
Abstract: The invention concerns a bearing arrangement of a displacer that performs a rotating translational motion about an eccentric path in the displacement chamber of a positive-displacement machine; it lies sandwiched between two side walls, covering it on both sides, of the casing of the displacement chamber. In particular for displacement machines designed for low rates of flow, a magnetic aligning device is proposed, comprising one or more permanent magnets fastened to the displacer, for each of which a stationary homopolar permanent magnet is arranged in the casing walls mentioned so that the mutually repulsive force acting between the permanent magnets facing one another forces the nonmagnetically constructed displacer onto the largest possible eccentric path within the also nonmagnetically constructed displacement chamber.

Patent DE-3706392-A1 (DE)
Title: Light box
Inventor: TEGTMEIER FRIEDRICH
IPC: G09F13/04
Filed: 1987-02-27
Abstract: Light boxes for showcases (show windows), slide boxes, illuminated signs and the like consist of at least one picture carrier, at least one glass pane covering said picture carrier, at least one luminous element, and are used, for example, as advertising panels or timetable display boards in railway stations. As often only little space is available for this purpose, the outer frame of the light boxes must be kept relatively small (slim). It is therefore common for illuminated light boxes to have a depth of 70 to appr. 200 mm. In order to accommodate an illuminated poster carrier in the outer frame, a space-saving lamp arrangement is therefore needed. For this purpose, fluorescent tubes are commonly used which are vertically arranged in the poster carrier and which transilluminate the advertising medium as well as the pane receiving the said medium, the lamps showing on the pane or on the advertising medium and the light values on the poster surface differing strongly. When high intensity levels of illumination continue over a long period, the poster surface can even discolour. The novel light box is intended to make it possible to illuminate the picture carrier surface more evenly. A light box for showcases, slide boxes, illuminated signs and the like consists of at least one picture carrier, at least one glass pane covering said picture carrier, and at least one luminous element, the pane (4) being provided on the side facing the picture carrier (2) with a layer (5) which is transparent and reflects and disperses part of the light.
