Title: Large flap valve sealing spring - acts on sealing surface and has pre-curved sealing spring straightened on assembly by tensioning spring
Inventor: KUCKERTZ WILHELM
IPC: F16K1/20
Filed: 1989-06-13
Abstract: The seal for a large flap valve consists of a sealing spring (6) and a tensioning spring (7) fixed to either the valve flap or housing. Before assembly, the sealing spring is curved to an extent that, when assembled, it is straightened under the action of the tensioning spring.

Patent DE-3925494-A1 (DE)
Inventor: BONFIGLIOLI GIUSEPPE
IPC: B07C5/34
Filed: 1989-08-01
Abstract: The method involves evacuating a space 10 surrounding part or all of a filled sealed bottle, tub, jar or phial 1, 2 to be tested and allowing a certain period of time to lapse while conditions stabilize, whereupon the pressure level in the space is measured and compared with a given set point. Where the effective pressure level measured differs from the set point by an amount greater than a maximum permissible margin the container will be rejected. A plurality of similar phials may be surrounded by a common evacuating space for testing together. For testing single containers of varying sizes a cylindrical enclosure with a piston adjustable vary the enclosure space according to the size of the container is provided (Fig. 4). In Fig 3 (not shown) a carousel feed arrangement checks containers in sequence and rejects unsuitable ones. <IMAGE>

IPC: G11B7/085
Filed: 1989-09-30
Abstract: A direction-determination logic is used in compact-disc players to establish in which direction the scanner is travelling across the tracks of the disc after either an intentional jump or an unintentional one caused by a knock, for instance. In order to determine in which direction the scanning light beam is travelling across the disc tracks, the phase difference between a track error signal (TE) and the envelope of the HF signal (HF) which generates the scanning light beam is only evaluated if the speed with which the light beam travels across the tracks is below a given value. The logic of the invention for the determination of the direction of motion of the scanner can be used in compact-disc players, video-disc players, DRAW-disc players and magneto-optical instruments.
