Title: Stabilising brake for trailer - has independent control to counteract slewing by selective brake application
Inventor: KRUNKE BERNHARD
IPC: B60T8/24
Filed: 1979-04-12
Abstract: A stabilised brake control for a trailer has an independent operation so that the trailer can be braked without the towing unit brakes applied. A sensor on the towing unit determines the amount of slew on the trailer and operates the trailer brake automatically to stabilise the vehicle. The amount of slew is determined by a mercury switch, or a servo control and operates the fluid-or cable brake to the trailer. The brake control can be linked to a time control so that the trailer brakes can be applied fractionally before the towing unit, and ensure a stable retardation.

Title: Stripping of silicone insulation from thick optical fibres - by two intertwined polyamide thread loops on bowed spring
Inventor: WENGEL JUERGEN ING GRAD
IPC: H02G1/12
Filed: 1979-08-11
Abstract: Thick-cored, optically-conductive fibres are threaded singly between two intertwined loops of polyamide threads, and are rotated around the axes of the threads so that the separate polyamide threads enclose the fibre by arcs covering more than 180 degs., in a process for stripping off the silicone isolating layer. The threads are then pulled outwards vertically to the axis of the optical fibre and tha silicone layer is cut through. The threads are arranged as two loops engaged with each other between the two legs of a "U"-shaped leaf spring. The device simplifies and speeds up the stripping of the ends of optical fibres for insertion into sockets and/or splicing without risk of damage.

Title: Ultrasonic technique for fluid flow speed measurement - using three sound converters fixed to prisms, two on one side of flow tube and electronic circuit to compensate for time delays
Inventor: KOUNO MASARU DIPL ING
IPC: G01F1/66
Filed: 1979-11-22
Abstract: In one example of the ultrasonic pick-up unit, two acoustic converters (1a, 1b) are mounted on an oblique face of a corresponding prism (2a, 2b) on either side of a hollow tube (3). The converters are typically of the Pb-Zr-Ti type. A fluid (4) flowing through the tube with a velocity V at an angle THETA to the normal to the light path, leads to a sound transit time, in addition to the delay time in the prisms, of T1(T2) = D/cost (C+Vsin THETA), where C is the sound velocity and the positive (negative) sign is taken for T1(T2) depending on the direction of fluid flow. Improved accuracy is obtained by adding a third prism abutting against the first (2a) so that an additional signal is obtained from reflection from the internal face of the hollow tube. The compensation signal is fed into the external electronic circuit, with a delay unit, a compensation circuit and an integrator.
