Title: Automobile braking system - double circuit front circuit failure results in automatic maximum pressure in rear circuit
IPC: B60T11/34
Filed: 1973-10-23
Abstract: The pressure source is a tandem master cylinder (10). One brake circuit (14) connects the first chamber to a set of brake cylinders (16) on the front wheels (18).

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
IPC: D01H4/32
Filed: 1974-09-13
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.
