Patent DE-3836211-A1 (DE)
Title: Device for providing stackable products
Inventor: GEHWEILER BERNHARD
IPC: B65G1/137
Filed: 1988-10-24
Abstract: For the purpose of filling-level monitoring of the supply magazines (V) arranged along a conveying device (B), every supply magazine (V) is assigned a code carrier (Ct), which can be output by the corresponding products-output apparatus (WA), and, additionally after the last supply magazine (V), there is provided a reading station (Ls) for identification of code carriers (Ct) guided past on the conveying device (B). The position of the code carrier (Ct) in the stack of the products (W) can be freely selected by the user. If the code carrier (Ct) is put on the uppermost product (W), it is expelled with the last product (W) and the reading station (Ls) reports that the assigned supply magazine (V) is empty. If the code carrier (Ct) is inserted in the product stack, detection by the reading station (Ls) means that the assigned supply magazine (V) will be empty after, for example, three further products (W). The filling-level monitoring device according to the invention is very reliable and can be realised with low costs. Retrofitting of existing installations is possible at any time. <IMAGE>

Title: Method and apparatus for cooling the air in mines
Inventor: BOETTGER JUERGEN
IPC: E21F3/00
Filed: 1988-11-02
Abstract: To cool the air in deep mines with the use of a vaporising and condensing cooling agent, the heat to be extracted from the air vaporises the liquid cooling agent underground, which is drawn off from the mine as gas. The vaporised cooling agent is condensed at the surface while cooling down and is expanded and is then fed back into the shaft in counterflow to the gas drawn off from the mine with simultaneous mass transfer with this gas for renewed vaporisation.

Title: Method for determining the position of a positionable surface, and a position sensor (encoder)
Inventor: KELLNER HELMUT
IPC: G01B11/00
Filed: 1989-03-25
Abstract: The invention relates to a method for determining the position of a positionable surface relative to a reference surface, and to a position sensor. Arranged on the positionable surface and/or the reference surface are marks which extend in two coordinate directions, specifically preferably in the X-direction and Y-direction. These marks are scanned and jointly calculated by a coordinate computer. This results in coordinate values which directly represent the relationship of the surface to be positioned with respect to the reference surface, and errors which can arise from the movement of other parts when deriving the coordinate movements being sought are avoided.

Patent DE-3928017-A1 (DE)
Inventor: MEINDL THEODOR
IPC: B65G47/66
Filed: 1989-08-24
Abstract: Method and installation for converting multi-track flow of containers into a single track flow, wherein an infeed conveyor is slanted relative to the horizontal plane, an intermediate conveyor is slanted at the same angle and so is a discharge conveyor. The intermediate conveyor is at least as wide as the infeed conveyor and abuts onto it. The discharge conveyor is arranged parallel and lateral to the intermediate conveyor. There is a cross-over plate between the infeed and intermediate conveyors. The advanced containers are first pushed onto the cross-over plate by the containers coming in on the infeed conveyor and they remain abreast of each other as they are then pushed onto the intermediate conveyor, whereby they are gradually accelerated to a speed which is lower than the speed of the discharge conveyor. The cross-over between the individual belts of the intermediate conveyor, which respectively run at speeds which increase down the slant onto the discharge conveyor, results from the downward force generated by the slant.

Title: Access flap for auxiliary power unit on aircraft - is automatically closed by flow of air stream over fuselage
Inventor: HAAS JAN THOMAS
IPC: B64C1/14
Filed: 1990-06-29
Abstract: The aircraft has an auxiliary power unit installed in the tail end of the fuselage.  Access to the unit, for maintenance purposes, is provided by means of two hinged flaps (2,3). Each flap (2) is attached by means of two hinges with arms (4,5) of different lengths.  The arm (4) of the rear hinge is longer than the arm (5) of the forward hinge.  This arrangement of the hinges causes the angle of the flap to the airstream when the flap is open to be such, that the airstream exerts a force on the flap which causes it to close.  Thus if flap should accidentally open in flight it is automatically closed by the airstream. USE - Auxiliary power units for aircraft with automatically closing access flaps.
