Title: Glue basin
Inventor: BECKER JOERG
IPC: B05C11/11
Filed: 1983-10-10
Abstract: A glue basin for an apparatus for gluing flat articles to paper sheets or the like contains a glue chamber formed by additional walls, where the free space between the glue chamber and the side walls of the glue basin acts as an overflow. The liquid build-up formed between the end walls of a dip roller and the adjacent wall of the glue chamber owing to the rotation of the dip roller can thus flow out over the edges of the glue chamber without causing a soiling of the adjacent portions of the whole apparatus. At the same time, the liquid level of the glue or adhesive within the glue chamber can be sufficiently high that a complete wetting of the dip roller with glue is ensured.

Title: Sausage-filling machine with a device for forming the end and a cutting-off device for sausages
Inventor: SCHNELL KARL
IPC: A22C11/10
Filed: 1984-03-10
Abstract: Adjacent ends (5 and 6) of a filled sausage skin which is being discharged are formed using pairs of squeezing plates (4), the piece situated between the operating pair of squeezing plates and the sausage-filling pipe (1) being rotated about its longitudinal axis during the squeezing process. The squeezing plates are situated at a distance which is equal to the desired sausage length on two circulating endless elements (10 and 11) which have runs which operate parallel to one another. The distance corresponds to the sausage thickness. In order to be able to divide the sausage strand, which is being discharged, into individual sausages, pairs of sausages or groups of sausages, a cutting-off device (9) is located in particular at the outlet end of the squeezing device. It has at least one cutting knife (9) which is mounted on a squeezing plate (2, 3) so as to be displaceable transversely to the direction of advance of the endless element. The operating advancing movement of the cutting knife (1) is obtained using a stationary moving-on element (21) having a moving-on surface (23). The latter extends towards the operating run of the endless element (11) in question, especially the lower one. Looking in the direction of circulation of the endless element, the moving-on element (21) is adjoined by a further moving-on element (22), the moving-on surface (24) of which also inclines towards the endless element (11). Because it is situated on the other side of the endless element, however, its moving-on surface (24) causes the cutting knife (19) to return to its starting position. <IMAGE>

Title: Protection circuit arrangement for an electric motor
Inventor: GAKENHOLZ H WERNER
IPC: H02P7/03
Filed: 1984-03-24
Abstract: A protection circuit arrangement for an electric motor which is supplied from a voltage source and whose rotation direction can be reversed and which has a manually operable polarity-reversal switch and a switching element, which interrupts an operating circuit in the event of the electric motor being overloaded, is intended to be constructed preferably for both rotation directions of the electric motor such that the electric motor can be driven in the one direction when it is blocked in the other direction and the switching element has triggered. This is achieved in that two switching elements are provided, of which the one can be short-circuited in the one polarity direction of the electric motor and the other in the other polarity direction of the electric motor. Both switching elements switch as a function of the current flowing through them and are not subject to the heat of the electric motor.

Patent DE-3426135-A1 (DE)
Title: Tandem aircraft having an integral surface or surfaces, which can be folded
Inventor: BRUEMMER FRIEDRICH DIPL ING
IPC: B64C39/08
Filed: 1984-07-16
Abstract: The ultralight aircraft consists of a leading wing and a trailing wing, of approximately equal size, and a correspondingly designed integral surface or surfaces. A double pyramid is produced by X-shaped bracing via a central strut. The lateral axis and longitudinal axis can be controlled by deforming the parallel strut which connects the leading wing and trailing wing. The incidence angle range of the integral surface or surfaces is adjustable, acts in unpowered flight as a regulating surface for the speed when the incidence angle is positive, and acts as a ballast surface with the best gliding figures when the incidence angle range is negative. In this case, it can function as an elevator or as a landing brake and dive brake with a severely positive incidence. The entire aircraft can be folded. The dimensions are reduced to that of a car. In order to produce integral lift in the case of a propeller-driven design, the propeller jet is directed onto the integral surface or surfaces and is deflected downwards. Integral lift is produced by utilising the ground effect. A propeller travelling position can be planned from the start which does not achieve the best motor efficiency until the lift-off speed has been reached.
