Patent DE-3728656-A1 (DE)
Title: Flat-bed knitter fabric take=off - has bar with take=off belt to pinch fabric against rear of needle beds
Inventor: MESTRE MAS MATIAS
IPC: D04B15/90
Filed: 1987-08-27
Abstract: The fabric take-off mechanism on a flatbed knitter has a reciprocating sheet bar moving longitudinally below the needle bed. The length matches the needle bed length and there is a blunted upper edge for at least one take-off band to pass round to be tensed between the upper edge of the sheet bar and a drive roller further below the needle beds. The sheet bar is flexed against the rear side of the needle beds so that the upper edge carrying the take-off band pinches the fabric against the needle bed to prevent any reverse movement by the material. The upper edge of the sheet bar acts as a mounting for a longitudinal take-off roller, matching the width of the needle beds, which projects beyond the edge and carries the take-off band passing round it, so that the belt tension acts as a clamp on the fabric against the rear side of the needle beds. -

Title: Walking device and method for moving fluid-borne loads
Inventor: FLOHR WILFRIED DIPL ING
IPC: B62D57/00
Filed: 1988-05-13
Abstract: The invention relates to a walking device and a method for moving fluid-borne loads, in particular for sequences of movement on an unprepared and uneven underlying surface. The object of the invention is to find a self-propelling walking device which travels around corners and has an integrated slideway, and the method for moving fluid-borne loads by means of this device. This is achieved by virtue of the fact that a slider is arranged between a sliding part, comprising a runner-shaped transportation shoe in contact with the underlying surface and a frame arranged thereon, and a supporting structure, comprising a laterally guided supporting plate, the underside of which is designed as a sliding surface. A bellows is arranged on each of the two sides and horizontally between the frame and the feet connected to the supporting plate. Both the slider and the bellows can be supplied with a fluid and the sliding part and supporting structure are arranged such that they can move with respect to each other. A second bellows, which can also be supplied with the fluid, can be arranged between the transportation shoe and the frame. Arranging a plurality of sliding parts under a load and supplying the bellows with a fluid alternately and staggered in time results in a continuous translation of the load which is self-propelling and travels around corners.

Inventor: HOFBAUER PETER PROF DR
IPC: F02B33/36
Filed: 1989-01-11
Abstract: Two-stroke internal combustion engines with a piston-controlled inlet and outlet and a scavenging pump are known. In these engines, exact separation of the combustion mixture from the exhaust gas and pressure-charging by means of the outlet pressure are not possible. To eliminate these disadvantages, the new two-stroke internal combustion engine has the features that the scavenging pump brings about a first and a subsequent second delivery air flow during the inlet opening phase (EÖ-ES), fuel being injected during the second, and that the outlet opening phase (AÖ-AS) is complete before the end of the inlet opening phase (ES). The two-stroke engine designed in accordance with the invention is suitable for use in road vehicles. <IMAGE>
