Title: Alkaline earth haloapatite phosphors - thermally refined by a continuous process
Inventor: PERRY WILLIAM CHARLES
IPC: C09K11/08
Filed: 1971-07-19
Abstract: The phosphor precursor material is formed in friable, coherent, uniform size briquettes and fed continuously into a furnace at >800 degrees C. The rate of passage is such as to allow the material to be heated to incandenscence, after which the briquettes are crushed to yield phosphor powder of uniform particle size. Spec. the phosphor is a Sb-activated alkaline earth haloapatitie which is treated in the furnace at 1050-1200 degrees C and rapidly cooled before crushing. The furnace used is either a horizontal tunnel type with the briquettes transported through, or a slightly inclined rotary furnace into which the material is fed at the higher end. Material of uniform particle size and improved homogeneity and crystallinity is produced. The use of special crucibles requiring careful thermal treatment over long periods is eliminated, the furnace residence time being ca. 40 mins.

Title: Pressurised water reactor steam and feed water system - - with first and second stage turbine intermediate superheater
Inventor: SCHABERT HANS-PETER DIPL ING
IPC: F01K7/40
Filed: 1971-12-24
Abstract: Main steam and feed water system applicable to a pressurised water reactor with steam raising units and turbo-generators. An intermediate superheater is interposed in the interconnecting steam line between the first and second stage turbines and condensate from the heater is returned by a centrifugal pump to the feed water train downstream of the high pressure feed heater.

Title: Fibreboard edges strengthened by impregnation with resin - esp for building partitions or suspended ceilings
Inventor: STEIN GUENTHER VON
IPC: E04C2/16
Filed: 1974-06-05
Abstract: A method of strengthening and reinforcing the edges of fibreboards, esp. mineral fibreboards, consists of impregnating the edges with a liquid, setting resin. Preferably, the depth of penetration is determined by the viscosity selected for the resin. Impregnation may be by dipping. Where there are grooves or holes, the resin is sprayed into these to avoide any omitted areas. Preferred resins used are polyester, epoxy or polyurethane. Esp. for mineral fibreboard or other types of fibreboards used for partitions, suspended ceilings, acoustic ceiling, decorative panelling or the like. The strength imparted to the edges of the fibreboard is virtually equal to that of the resin itself when solid. This protects the panels both during transportation and also when suspended, for example by means of angle irons, T-beams and the like.

Title: Single channel direction finder - sequentially scans auxiliary antenna and crossed antenna system voltages
Inventor: BLACKERT HANNO DIPL ING
IPC: G01S3/14
Filed: 1974-07-09
Abstract: In the first phase h.f. voltage collected from the auxiliary antenna and from the reception channel is applied to an oscillator which is synchronised with the voltage from the reception channel. This oscillator serves during phase two and three as reference generator for analysis of bearing voltages x and y delivered by the crossed antenna system and amplified and transposed in the receiver. The analysis consists of finding the peak values X and Y and their phase differences, stored after their analogue-digital conversion and applied to a programmed computer which determines the bearings' azimuth and the splitting ratio b/a.
