Title: Aligning carded fibres fed to open end spinning cups - using deflectors in cup to contact fibre ends with cup interior prior to fibre release
Inventor: SAFAR VACLAV
IPC: D01H4/08
Filed: 1974-08-26
Abstract: Carded fibres supplied to the collecting surface of an open-end spinning cup are aligned by passing the fibres in contact with a distributor located in the cup and which allows the fibre ends to contact first a slide wall and use the braking effect to align the fibres during release into the cup. Alignment which leads to uniform fibre distribution also results in stronger spun yarn. Preferably the fibres are contacted with their leading ends along a path of the slide wall which passes through an imaginary plane located near the collecting surface, whilst the trailing ends of the fibres are contacting the slide wall along a path passing through a further imaginary plane located axially farther away from the collecting surface.

Title: Vehicle hydraulic servo steering - has dividing valve between servo- and metering pump connect to steering cylinder
Inventor: KOBALD WALTER
IPC: B62D5/093
Filed: 1974-09-12
Abstract: On previous designs the entire flow quantity required for the operation of the steering cylinder and supplied by the servo pump was ducted through the material pump, which consequently had to be quite large, in order that a limited number of steering wheel turns would be sufficient for the complete range of steering. A flow dividing valve fitted between the servo pump and the metering pump eliminates the above shortcoming. One connection of the valve is piped to the metering pump inlet, the other to the metering pump outlet, which in turn is connected to the steering cylinder via a control valve.
