Patent GB-2113038-A (GB)
Title: Dropped sample data rate reduction system
Inventor: COLEMAN CHARLES H
IPC: H04N9/808
Filed: 1982-10-25
Abstract: A method and apparatus are disclosed for eliminating or dropping digital samples from a data stream of samples to reduce the data rate for transmission of the data stream through a transmission channel, such as a data record and reproduce system or the like, and for subsequently reconstructing the original data stream by using the unaltered and recovered digital samples to generate an interpolated value for each of the samples that has been dropped. A finite impulse response multi-term digital filter is used to generate the interpolated value for the samples that have been dropped. Advantages reside in the fact that errors are not propagated during multiple generation recording or transmission, since unaltered sample values are always used to produce the interpolated value for the dropped sample that is being reconstructed. The invention has particular use in video recording and reproducing wherein it is desirable to record a digital data stream at the lowest practicable data rate. <IMAGE>

Patent GB-2142328-A (GB)
Title: Improvements relating to the manufacture of cement
Inventor: STANLEY GEORGE
IPC: C04B7/38
Filed: 1983-07-01
Abstract: A process for preparing the raw materials for feeding to a vertical kiln for cement production is described. Such kilns have the disadvantage that the fuel moves counter to the air and combustion gases, and this causes undesirable secondary reactions resulting in the production of harmful carbon- monoxide and the premature burning of the fuel. To combat such problems, the fuel is wet with water and mixed with previously ground raw material so that each fuel particle attains a protective shell of mud. The wet raw material is first passed through a primary crusher (3) and then mixed with sold fuel. The mix is then passed through a web ball mill (11) and ground to form a slurry. Then the slurry is passed through a filter (13) and/or drier (17) to remove excess water before it is passed to a pelletiser (15) and finally, the vertical kiln (19). <IMAGE>

Title: Light-polarising material
Inventor: GODFREY ROBIN EDWARD
IPC: G02B5/30
Filed: 1983-08-04
Abstract: A light-polarising material capable of effectively polarising light of high energy density such as lasers comprises one or more sheets of polyvinylalcohol incorporating a light-absorbing material which does not bleach at said high energy density, the polyvinylalcohol and the associated light-absorbing material being substantially uni-directionally oriented to render the material dichroic and the amount of the light-absorbing material per unit volume of the polarising material being sufficiently low for the heat generated by light absorption to be dissipated rapidly enough to prevent the polarising material from being degraded and thereby lose its ability to polarise said light. The light-absorbing material may be a dye, e.g. an azo, azine or oxazine dye; or may be provided by subjecting the polyvinylalcohol film to a dehydration reaction, e.g. by heating in the presence of hydrochloric acid, to introduce polyvinylene sites in the film.
