Title: Inorganic filler-containing vinyl monomer compositions and process for the production therefrom of polymer particles
IPC: C08F2/44
Filed: 1982-03-05
Abstract: A polymerizable composition contains by weight 20 to 90% of a vinyl monomer (e.g. styrene), 80 to 10% of an inorganic filler (e.g. a metal hydroxide), and, by weight of the filler, 0.1 to 5% of a silane coupling agent and 0.01 to 2% of an accelerator for the silane, e.g. dibutyltin dilaurate. Optionally, the composition contains 5 to 50% by weight of the monomer of a vinyl polymer, e.g. polystyrene, which is soluble, at least at polymerization temperature, in the vinyl monomer. To produce polymer particles, an initiator is added and the composition is subjected (i) to preliminary partial bulk polymerization until the 20 DEG C viscosity is 100 to 10,000 cp and then (ii) to either aqueous suspension or further bulk polymerization to complete the vinyl monomer polymerization.

Title: Flywheel mechanisms for anti- skid braking systems
Inventor: FARR GLYN PHILLIP REGINALD
IPC: B60T8/74
Filed: 1982-11-04
Abstract: The invention is concerned with reducing the deceleration rate of an over-running flywheel following actuation of an associated camming means, by reducing the torque of an axially biassed clutch, to provide a more reliable wheel speed analogue. In one construction, Figure 7, the clutch consists of two clutch discs (97,98) engaging with the thrust member (95) of the camming means (91,92,93,95). The clutch torque is reduced following expansion of the camming means by reducing the frictional engagement force between one disc (97) and the thrust member, this being effected by a change in the mechanical advantage of a lever (76) acting on the flywheel (74) as the lever accommodates expansion of the camming means. in another construction, Figure 2 (not shown), the fluid pressure force on a clutch biassing piston (24) is varied to vary the clutch torque, and in yet other arrangements, Figures 4 and 5 (not shown), a magnetic clutch biassing force is varied. <IMAGE>

Title: Light emitting device and optical signal processing system employing the same
Inventor: TAKAHASHI TAKEO
IPC: G11B7/126
Filed: 1984-08-07
Abstract: A laser diode is energised by a direct current on which is superimposed an alternating current of a frequency between 1 DIVIDED 2 and 2 times the resonance (relaxation) frequency of the laser diode (5). The energising signal has a highest current value greater than the lasing threshold of the laser and a lowest current value smaller than the lasing threshold. The laser generates multiple modes with a broadened spectrum and reduced coherence. This reduces mode hopping noise. The laser (5) and its drive components 14 to 16 are mounted on a ceramic circuit board (17) and contained within a housing (10). The laser can form part of an optical signal processing system, eg for an optical video disc, which due to the reduced mode hopping noise, scoop noise and speckle noise provides a system which is substantially free from noise during signal recording and reproduction. <IMAGE>

Title: A pneumatic, e.g. vacuum operated, servo unit especially for motor vehicle braking systems
Inventor: FUGEN FRIEDRICH WILHELM
IPC: F16J3/06
