Patent GB-2070989-A (GB)
Title: Improved surface cleaning machine
IPC: B24C3/06
Filed: 1981-03-02
Abstract: In a surface cleaning machine of the kind in which abrasive grit is projected at high velocity against a surface (4) to be cleaned, rebounded grit and dirt pass upwardly through a reclaim channel (8) to a first air cleaning stage in a first hopper (13) and thence through a rotating drum valve (14) to a cleaning space (15).

Title: Clamping mechanism for a document file
IPC: B42F13/42
Filed: 1981-04-22
Abstract: A document file clamp comprises a flexible plastic tubing (12) which is secured to a file by being threaded through punched holes in the file documents and then through holes (18) in a clamping plate (20). The ends of the tubing (12) are secured so as to hold the documents (16) firmly in place by passing them beneath two transversely extending flanges (22) which are provided with lips (24) to prevent the tubing (12) being accidentally dislodged. The tubing 12 can be formed in three portions and the two end portions (28) can be fitted onto lugs (26) on the edge of the clamping plate (20) to provide a U-shaped clamp loosely retaining the documents. Separation of the end portions (28) from the middle portion then provides a transfer element to hold papers while others are inserted or removed. <IMAGE>

Patent GB-2083214-A (GB)
Title: Dimension monitoring apparatus
IPC: G01B11/04
Filed: 1981-08-18
Abstract: Apparatus for monitoring the width of moving articles, such as biscuits moving on a conveyor, comprises scanning CCD array (6) which scans the article obliquely many times and produces video signals (8, 55) the period of each which depends upon the length of the scanned oblique strip of the article. The array is angled at 30 DEG -60 DEG (preferably 45 DEG ) to the direction of movement. Clock pulses (54) are counted for each scan, and the counts corresponding to the leading and trailing edges of the video signals (55) are stored in a RAM (12). A microprocessor unit (14) determines, for a rectangular or circular article, which scans relate to the maximum width of the article and calculates the width of the article. The MPU 14 can also determine the length of a rectangular article and whether the article is skewed. Compared with transverse scanning, fewer scans per article are needed data relating to more articles can be held in a given size of RAM. Photodetectors are also used to sense the speed of the conveyor, and the colour and thickness of the articles. <IMAGE>

Title: Manufacture of signs
Inventor: WOODMAN MICHEL ANDRE GHILAIN
IPC: G03F7/00
Filed: 1982-09-07
Abstract: Instead of engraving or signwriting, metal signs are provided with the sign legend using a positive working photosensitised coating which may be applied to the sign structure during its manufacture.
