Patent GB-2042077-A (GB)
Title: Filter presses
IPC: F15B15/26
Filed: 1980-01-28
Abstract: A plate type filter press, which is opened and closed by at least one hydraulic piston-and-cylinder unit, has a mechanical lock to lock the press in the closed position so that it is not necessary to maintain a high hydraulic pressure to keep the press closed. The mechanical lock may be a set of claws on the hydraulic cylinder to co-operate with a locking ring on the piston rod, with a hydraulic lock cylinder to retract the claws for unlocking, or a lock gate that is introduced into or retracted out of the path of a lock collar on the piston rod by operation of a lock cylinder. The press is first closed with a predetermined high hydraulic pressure that compresses the filter press pack sufficiently for easy movement of the mechanical lock into locking position, and then operation of a lock limit switch automatically stops the hydraulic pump and energises a bleed valve to reduce the closing pressure to a level at which the press pack compression is relaxed enough to give firm lock engagement.

Title: Epitaxial growth of garnet films
IPC: C30B19/02
Filed: 1980-01-28
Abstract: The described invention relates to the growing of garnet films. The specification describes the growing of a garnet film by the liquid phase epitaxy process in which in order to reduce strain during she growth of a plurality of substrates the substrates are separated during the epitaxy process by means of a powder material including lead oxide which is applied prior to the epitaxy process. The material acts to separate the substrates in order to reduce strain but the separation is insufficient to allow the melt in which the films are grown to seep between the substrates. The invention is particularly applicable to the growing of garnet films for the production of magnetic bubble devices.
