Patent DE-3535166-A1 (DE)
Title: Lift aid on aircraft wings
Inventor: HEINRICH CHRISTIAN
IPC: B64C21/00
Filed: 1985-10-02
Abstract: In order to increase the lift from aircraft wings, a reduced pressure is produced on the underneath of the profile (1) in the region of the trailing edge (2). This reduced pressure is produced on the principle of a Venturi tube. It is passed through a gap (slot) (4) to the top of the wing and there influences the prevailing flow. Since the reduced pressure which is produced depends on the airspeed, the lift coefficient cA of the wing is in consequence also dependent on the airspeed. In order to increase the maximum lift coefficient cAmax, the gap (4) is covered on both sides by a perforated strip. In this case, a lift aid has been created using simple means, which is used both in slow flight as well as in cruising flight and when gliding. <IMAGE>

Title: Device for catching fuel vapours when filling a fuel tank
Inventor: KLEINEBERG WOLFGANG DIPL ING
IPC: B60K15/04
Filed: 1987-02-14
Abstract: In a device for catching fuel vapours when filling a fuel tank a seal enclosing the pump nozzle pipe inserted for refuelling is arranged inside the tank inlet and the tank volume remaining inside the tank above the maximum fuel level is connected both by way of a discharge line, which can be sealed off by means of an automatically closing valve, and by way of a ventilation and venting line to an activated charcoal filter connected to an intake line. When refuelling, the valve of the discharge line is automatically set to its open position. The fuel vapours produced by foaming of the fuel flowing into the tank are prevented from escaping out of the filler neck but can flow out by way of the opened discharge line to be adsorbed into the activated charcoal filter, from which they are fed to a consumer by drawing off. On completion of the filling process, the discharge line is automatically closed by the valve, thereby ensuring that no fuel can escape from the fuel tank, for example in the event of the vehicle turning over.

Title: Movable arm
Inventor: LACHNER HANS DIPL ING
IPC: B25J17/02
Filed: 1987-04-09
Abstract: A known movable arm for holding and manipulating grippers or equipment consists of a series of interconnected elements of the same type, which are interconnected, on the one hand, by a ball joint resistant to tension and compression and, on the other hand, by two linear motors, which likewise engage on the neighbouring elements in a spatially articulated manner and by means of which the neighbouring elements can be polydirectionally pivoted about the ball joint. To construct such an arm to be more stable and to be stiff against torsion, the invention proposes that the elements are in each case constructed as tetrahedrons (1), of which in each case two corners are arranged one behind the other in the longitudinal direction of the arm and are interconnected in a polydirectionally articulated manner and to be stiff against torsion in the longitudinal direction of the arm by joint pins, in particular by universal joints (2), whereas the linear motors (3) engage on the other two corners of the tetrahedrons (1). The arm according to the invention can be used as a manipulator arm for excavators and hoists or as a robot arm. <IMAGE>

Patent DE-3717348-A1 (DE)
Title: Single-valve piston dispenser
Inventor: RIDDER JOSEF
IPC: G01F11/02
Filed: 1987-05-22
Abstract: A single-valve piston dispenser manages with one outlet valve arranged on the discharge, namely by designing the actual dispensing piston simultaneously as an inlet valve. This is achieved by the dispensing piston having a diaphragm sleeve arranged on the tip and sealing against the piston rod, the sleeve being connected to a compressed-air or vacuum conduit led through the piston rod and being guided to and fro in the measuring space in order to suck in and then force out the exactly predetermined quantity to be dispensed. Particularly advantageous in this case is the fact that a very simple and effective device is created, which makes possible a simplification of dispensing devices of the type and especially takes into account the special problems of the milk trade. <IMAGE>

To minimise operating noise and optimise efficiency, it is proposed that the gears have a truncated-cone profile or a corresponding profile, that the sun gear and planet carrier be arranged on the input shaft or output shaft so as to be longitudinally displaceable, but non-rotatable, and that the rolling contact surfaces of the gears be pressed against one another by energy accumulators in the form of Belleville springs or the like which act on the planet carrier or on the sun gear.
Patent DE-3728129-A1 (DE)
Title: Laser arrangement consisting of an astable optical resonator and an additional partially-reflective surface
Inventor: HODGSON NORMAN DIPL PHYS
IPC: H01S3/08
Filed: 1987-08-22
Abstract: A large mode volume and high beam quality can be achieved using astable optical resonators. However, good beam quality is possible only if the output losses are low, so that these resonators can be used efficiently only in the case of active media having high gain. By arranging an additional partially reflective surface within or outside the astable resonator, the output losses can be reduced without adversely affecting the beam quality. This reduction in the losses results primarily from excitation of the convergent wave. Using this arrangement, even lasers having active media of large diameter and a low small signal gain can be implemented with high efficiency with diffraction-limited beam quality.

Patent DE-3738382-A1 (DE)
Title: Conveying duct for pneumatically conveying combustible materials
Inventor: JOSSI ARMIN
IPC: A62C2/12
Filed: 1987-11-12
Abstract: Arranged in the conveying duct (10) is a spark detector (12) which drives a swivel flap (15) which is arranged subsequently, is normally in the open position and in this position closes a discharging opening. The swivel flap (15) is connected to a spring energy accumulator (23) which, in the open position of the swivel flap (15), is blocked by a release mechanism (20, 25, 26). In order to shorten the time between the response of the spark detector and the effective bulkheading-off of the duct (10) by the swivel flap and thus also to reduce the length of the conveying duct (10), the release mechanism has an element (25) made of a brittle material which supports a lever (20) connected rigidly to the pivot pin (18) of the swivel flap (15) against a stationary abutment. On response of the spark detector (12), a striking mechanism (31) is driven via an amplifier (32), which mechanism destroys the element (25) virtually without delay. The conveying duct thus equipped prevents the spread of fires. <IMAGE>
