Patent EP-0011260-B1 (EP)
IPC: H02P8/00
Filed: 1979-11-12
Granted: 1983-11-30
Abstract: The invention comes within the field of equipment control. A method of shifting a moving unit from a first position to a second position by means of a stepping motor driven by a finite sequence of pulses, said moving unit being liable to oscillate about its equilibrium point, characterized in that as a function of the period and of the damping factor of the oscillation, the time intervals which separate said pulses are chosen so that the last pulse is applied to the motor at an instant when the oscillation resulting from the set of preceding pulses brings the moving unit substantially to the required final position and reduces its speed substantially to zero. It applies in particular to disc-type printers.

Abstract: A heat-insulating body such as a heat-insulating slab is made whose insulating and heat-absorbing material includes a fine powder, in particular a silica aerogel which is pressed to form the body. To carry out the pressing operation a sack-like sheath is required but between the sheath and the insulating material a separating agent is provided which results in the fact that the surface of the insulating material does not intimately engage with the sheath which is for example of glass fibre fabric, the sheath being movable with respect to the insulating material after the pressing operation. Apart from the fact that the sheath can be removed for any cases where it would be a cause of disturbance, additionally the insulating body provides improved bending properties and even when made with a high pressing rate has a homogeneous structure. To make the insulating body the separating agent may be applied to the inner surfaces of the sheath, the particulate insulating material then being introduced and the sheath sealed, whereafter pressure is applied.

Filed: 1981-07-16
Granted: 1988-09-07
Abstract: A glass fibre for optical communication is formed by a vapor deposition process on the inside surface of pure silica substrate tube. The substrate forms the outer cladding whilst the inner and core are formed by the deposited layers. An intermediate layer of the cladding has a refractive-index similar to pure silica but due to compensating dopants. Thus deposition and sintering temperature is reduced. The inner layer of the cladding is however undoped pure silica, thus reducing absorption losses in this important region.A step in a process for making optical fibres comprising collapsing a tubular substrate to provide a preform is carried out in a stream of pure chlorine vapour acting as a drying agent.
