Title: Filter press - with inflatable chamber for squeezing cake
Inventor: KITAJIMA SUSUMU
IPC: B01D25/12
Filed: 1971-12-23
Abstract: A filter press in which provision is made for squeezing the filter cake comprises filter plates each provided with marginally thickened areas with filtrate discharge channels. The plates have flexible sheets which have outwardly extending projections to provide channels for filtrate passing to the sheets from filter cloths, arranged over the sheets.

Patent DE-2339369-A1 (DE)
Title: Position selecting switch controlling actuator motor - comprises disc with spiral groove allowing several turns between limits
Inventor: LITTERST PETER
IPC: H01H19/60

Title: Periodically recurring signal subject to strong interference - is displayed by storing signal from one period for addition in next
Inventor: BRUEHL DIRK
IPC: G01S15/18
Filed: 1973-09-05
Abstract: The display of periodically recurring signals is subject to strong interference, such as echo impulses in shallow fishery soundings, and creates difficulties in the identification of the genuine signals. The process comprises storing a received signal during one period until the next reception period, when it is added to the incoming signal. The signal selected for display is that which exceeds a given, adjustable value. The received signal is prepared by an impulse formulator and input to storage cells through an addition unit. A stroke generator ensures that the contents of the cell are transferred to the next after a given time has elapsed. The outlet of the addition unit is connected to a threshold switch which is linked to a signal device.
