Patent GB-2228645-A (GB)
Title: Video tape recorder
Inventor: KODAMA MASAFUMI
IPC: H04N5/956
Filed: 1990-01-22
Abstract: In an improved helical scan type video tape recorder for reproducing a high quality video signal with no distortions from a single head, sag distortion (due to discontinuity of the signals) is eliminated by applying a continuous reproduced video signal, prepared by inserting FM signals reproduced by a pair of rotary heads 5a, 5b into no-signal field intervals of an FM signal reproduced by the single rotary head 5c, to a clamp circuit 21. Furthermore skew distortion may be eliminated by providing one horizontal scanning period of 1H between the last horizontal pulse in a signal field interval and the first horizontal pulse in a no-signal field interval of a reproduced video signal regardless of the type of scanning (such as interlace scanning) for preventing disturbances in horizontal synchronization. Phase distortion may be eliminated by combining a pseudo-vertical synchronizing signal from a circuit 900, which has a specific phase relationship with a video tape phase standard signal at any travelling speed of the video tape, with a reproduced video signal for preventing disturbance in vertical synchronization. …<IMAGE>…

Title: Computer based document printing system
Inventor: KENNEDY DAVID
IPC: G06F17/24
Filed: 1990-02-28
Abstract: A computerised document generating apparatus for use in generation and printing of documents having a relatively large number of data values. The apparatus utilises random access memory and permanent and exchangeable magnetic disks in a manner which allows use of data values from a large number of files without excessive requirements of the random access memory circuit during generation and printing of a document. This is achieved by use of a target file which is stored in the random access memory circuit, 24, and receives values from other files 25, 27 before generation and printing of a document. The data values of the target data file are independent and may be used without further processing involving reference to values of other files. The other data files are then transferred by writing them to floppy disc, 31 and fixed data relating to the format of the document to be printed are transferred to RAM for processing with target data file to generate a formatted document for printing, 33, 35. Such documents may include reports relating to performance of industrial processes, said reports including parameter values for the processes.   <IMAGE>

Title: Reclamation of used foundry sand
Inventor: JACOB HERMANN
IPC: B22C5/00
Filed: 1991-08-15
Abstract: A process is proposed for the selective reclamation treatment of used foundry sands in which separation of parts of the binding materials from the basic granular material is effected by mechanical means, and then the sand grains are accelerated to produce an abrasive action of the individual sand grains on each other. After that, in accordance with the invention, the separation of large and small grains is carried out and if required further thermal and mechanical treatment is effected to the smaller grains to remove binding material therefrom. This ensures a uniform treatment of the grains per unit mass, since the standard treatment is in general more effective for larger grains.
