Title: Waveguide coupler to fibre-optical light guide - by transparent optical cement or cinnamaldehyde of high refractive index
IPC: G02B6/30
Filed: 1974-09-24
Abstract: Light waves passing through fibre-optical light guides can be taken off from or fed into a dielectric wave guide at any desired point. This is done by arranging the fibre-optical light guide at the desired spot at a certain optimum angle, which depends on the excited mode of the waveguide, by means of an optical cement or a liquid such as cinnamaldehyde with refractive index higher than that of the waveguide. This is a simpler and more convenient way of joining a waveguide and a fibre-optical light guide at any point than prism or grating couplers.

Title: Electro-mechanical power transmission unit - has differential coupling and output shafts and power transducers
Inventor: MARMORAT JEAN-PAUL
IPC: H02K51/00
Filed: 1974-10-08
Abstract: This electro-mechanical vehicle transmission unit has a shaft (2) joined to the m ain engine and driving a differential gear unit with two output shafts. One shaft (4) drives an electrical generator (6) to energise an electrical motor (14) which is coupled to the second output shaft (5) which is a differential coupling shaft. When the output shaft is stationary, the differential gear drives the generator at full speed, thus causing the motor to accelerate the output shaft. At full speed, the drive is by mechanical linkage via the differential gear. Motor currents are optimised by a comparator system and this unit improves upon previous gear-box design for smoothness and efficiency.
