Title: Rotary valve for bagging asbestos from a hopper
Inventor: PITMAN JIM
IPC: B65G69/18
Filed: 1985-12-04
Abstract: The invention provides an asbestos filtering apparatus comprising a hopper 23 into which filtered asbestos falls, and at the base of the hopper there is a rotary valve 24 controlling the charging of the filtered asbestos from the hopper into a bagging unit 25 located under the rotary valve. The rotary valve comprises a cylindrical chamber containing a plurality of valve vanes 48 so that the filtered asbestos falls into the chamber between a pair of vanes and then the vanes are rotated to discharge the charge of asbestos between them into a bagging unit under the valve through an outlet 46 located to the underside of the chamber. Waste asbestos lagging 15 passes into the apparatus at 14, the whole apparatus being put under reduced pressure by pump 10. Cyclone 20 separates asbestos which falls into hopper 23; entrained dust is removed by filters 29, 38 in the next vessel which has a similar hopper 32/vaned rotor 34 arrangement. <IMAGE>

Title: Optical switch or information store
Inventor: WOIKE DR THEO
IPC: G02F1/17
Filed: 1986-10-28
Abstract: An optical switch or information store has a storage medium which is a Ba/Fe(CN)5NO/nH2O single crystal (1), light source(s) (I, II) for pumping and reading the medium (1) and a photodetector (5) for picking up and further transmitting the stored signals. This single crystal can be transformed into a long-living metastable state at a temperature of 200 DEG K by radiation of a defined wavelength ( lambda 1) and back into the original state by radiation of a defined different wavelength ( lambda 2). Since the regions of the single crystal differ in their transmission for radiation in dependence upon their state, the stored information can be retrieved and passed on by means of a photodetector which counts the transmitted or backwardly scattered photons. <IMAGE>

IPC: H01S5/00
Filed: 1989-07-19
Abstract: The laser, particularly adapted for operation in the self-pulsation mode, comprises a central mesa 30 formed in an upper cladding layer 24. Normally relatively thick sections are required at either side of the mesa in order to form a waveguide of sufficient to cause self-pulsation operation. In order to control the thickness of the upper cladding layer bounding the mesa is first formed by etching the regions bounding the mesa to relatively thin sections 24a, 24b capable of gauging by optical interferometry. A composite upper cladding layer is then formed by utilizing MOCVD crystal growth techniques to form a butter layer 32 on the upper cladding layer bounding the mesa, the butter layer having an aluminium content about the same as the aluminium content of the AlGaAs upper cladding layer. The composite layer functions as a comparatively thick waveguide which can be formed to the necessary thickness with adequate accuracy to provide a high yield when producing self-pulsation lasers. …<IMAGE>…
