Title: Eliminating cushion distortion using a glass plate
Inventor: HOUGAARD FINN
IPC: G02B27/00
Filed: 1988-04-26
Abstract: Cushion distortion is eliminated when adjusting reproduction equipment comprising a picture plane, an objective plane, and an original plane. The cushion distortion results optionally from a glass plate being inserted in the path of the rays. The path of light is the same irrespective of the direction in which the light moves. By employing this principle a cushion distorted picture can be reproduced as an undistorted picture if an additional glass plate of a suitable thickness is inserted in the path of the rays. The additional glass plate must, however, be situated on the opposite side of the objective. A glass plate supporting the light-sensitive material may not be quite plane either which can result in a certain degree of cushion distortion. Such a distortion can also be eliminated by the insertion of an additional glass plate in the path of the rays.

Patent GB-2222778-A (GB)
Title: Positive pressure filter respirator
Inventor: SIMPSON KEITH
IPC: A62B18/10
Filed: 1988-09-19
Abstract: The flow of air into a positive pressure filter respirator during exhalation is reduced without having to provide an inhalation valve by using an exhale valve which is a flap valve having a high cracking resistance but a low resistance to flow. The exhale valve has a pressure/flow characteristic (C, Fig. 1) in which the pressure resistance increases with flow from a cracking pressure greater than 10 mm water gauge at 30 litres per minute flow until at a flow rate in the region of 70 - 80 litres per minute, the pressure resistance across the valve falls such that the pressure across the exhale valve at a rate of flow of 85 litres per minute through the valve is less than 12.5 mm water gauge. This effect is achieved by using an exhale valve which is a flap valve having a flexible flap (2) connected to a circular stem (3) by a resilient fold (1) which permits the flexible flap (2) to move axially relative to the circular stem (3) as the rate of flow through the valve increases past 70 litres per minute. <IMAGE>

Title: Method and apparatus for the continuous non-destructive testing of articles
Inventor: BEER GERHARD
IPC: G01N29/00
Filed: 1991-03-13
Abstract: Elongate articles (e.g. in the form of tubes or pipes) are moved on a roll table 2 through two test blocks 8, 9 (e.g. magnetic or acoustic sensors) arranged in line. The test blocks 8, 9 are mechanically separate from one another and are electrically connected in logic terms to an electronic test unit 10. The latter evaluates the signals produced to determine the type and location of faults in articles. A difference in output between the two blocks 8, 9 is indicative of a false fault signal from either block and can thus be used to avoid unwarranted rejection of articles. The test blocks 8, 9 are disposed between a call station 1 and a sorting station 3. These stations 1, 3 are interconnected by the roll table 2. The sorting station 3 comprises a good tray 4 and a number of reject trays 5-7 for articles which are either correctable or no longer correctable. <IMAGE>
