Title: Remote braking control for railway - uses spaced signalling points along track for automatic warning of spacing from stop signal and gradient
Inventor: FRANK WERNER ING GRAD
IPC: B61L3/00
Filed: 1978-03-07
Abstract: The remote braking control for the train has two sets of trackside signal points set a distance apart and spaced from the final stop point by a fixed distance. The second signal point provides information to the train's sensors regarding the gradient up to the stop point. The spacing of the signals points provides the train braking control with an accurate speed signal which - with the gradient information - enables the braking control to provide a smooth and controlled retardation to stop the train at the selected point.
Patent DE-2810182-A1 (DE)
Title: Stitched moccasin shoe mfr. - using front tongue insert sewn to upper before sticking to sole
Inventor: GERHARD HELMUT KORBACH
IPC: A43B3/10
Filed: 1978-03-09
Abstract: The mocassin can be made by first stitching the front tongue insert (1) to the upper (3) so that it forms a right angle with the insert (1). The tongue can then be stuck to an underneath part which is made of the same leather material as used for the upper. Once the insert is stitched to the upper, the exact shape of a finished shoe is produced so that only the lower adhesive edge of the upper need be bent round and stuck to the underneath. The top parts of the shoe can thus be easily stitched since the shoe is at first open at the bottom.
Patent DE-2822299-A1 (DE)
Title: Flow regulator for fluid - has flexible walled chamber filled with low density fluid and acting as throttle valve
Inventor: BENDIXEN STEIN
IPC: G05D7/01
Filed: 1978-05-22
Abstract: The flow regulator, e.g. for drainage systems, consists of a control chamber (3) which is positioned in the pipeline carrying the fluid medium (1). The chamber contains a fluid medium whose density is lower than that of the flow medium. The upper wall of the chamber (4) is constructed from a rubber or other elastic material. The chamber has a lateral channel (5) through which the main flow can pass. The walls of this channel are also constructed from a flexible material (6). They are fixed at each end to a rigid plate (7) within the main pipe and to an outer wall of this pipe (10). The hydrostatic pressure in the chamber depends on the head of fluid (h1) in the main pipe. The hydrostatic pressure at the channel inlet depends on the head of fluid there (h2). The cross-sectional area of the flexible-walled channel is therefore varied so that the flow rate through it is held constant irespective of the fluid head.

Inventor: PLUEQUET HEINZ DIPL ING
IPC: F01M9/10
Filed: 1978-10-04
Abstract: An arrangement for lubricating, especially for internal combustion engines is disclosed. The circuit of the arrangement is fed with the lubricating medium, e.g. oil, by way of a pump which delivers oil from a source, as required through an oil cooler and a filter, to bearings of the engine which require lubrication, and to more remote bearings, such as are used in auxiliary equipment, e.g. off-gas turbo-superchargers. In the main pressure conduit, relatively close to the pump, there is provided a flow control device with a direct conduit being provided to communicate the pump with the more remote bearings. The direct conduit is connected to the circuit between the pump and the flow control device. As required, an oil filter can be arranged in the direct conduit. The flow control device is controlled by the fluid pressure prevailing in front thereof to open and is spring biased to close, with a further conduit also connected to the circuit between the pump and the flow control device, communicating the pump and the flow control device.
