Title: Liquid gasification esp. aeration for fermentation - with shaped vessel ends to form smooth flow throughout vessel
IPC: C12M1/08
Filed: 1974-08-29
Abstract: An aerating or gasifying plant for liquids esp. for fermentation processeS, comprises a cylindrical vessel containing a cylindrical guide tube with an extracting and mixing rotor at one end, the gas feed is at that end also, so that the liquid flowing from the tube is thoroughly mixed with the gas, before passing along the annulus outside the tube to the other end of the vessel.

Title: Memory for data in keyboard sequence - has rapid storage and retrieval by keyword comparator controlling shift register
Inventor: BULL ANTHONY VICTOR
IPC: G06F17/30
Filed: 1975-05-09
Abstract: A memory for data consists of a keyword and sets of data, with a shift register (RSR, MSR, LSR) for the sets of data and a terminal from which the data can be fed out in sequence, leading to a comparator (10) in which the keyword (K) of the momentarily fed-out data is compared with a wanted keyword, and whose output controls the feed-in or feed-out through the terminal to the shift register, the data stored on one or other side of the connecting lead being suitably shifted when a set of data is to be fed in or out. Then shift register may be a linear two-way register with the connecting lead in its centre. The arrangement facilitates the easy recording of data in the order of the keywords, with correspondingly simple retrieval.

Title: Instrument rack for dental table - has slots feeding hoses towards take up roller under table
Inventor: PIETSCHMANN HELMUT
IPC: A61G15/16
Filed: 1975-11-26
Abstract: A rack (6) for dental instruments, attached to a swinging table, has the instruments laid out each in its own notch. Behind each notch, and below the surface of the table (10) is a narrow compartment (3) into which that instruments hose is neatly stowed. The hose is stowed automatically by a roller, which runs on the gently sloping floor of the compartment. The loop of hose fits round the roller and is carried down into the compartment by the roller weight. As it reaches the lowest point (hose fully stowed), the roller operates mechanical switchs to turn off the power, etc. The roller then comes to rest in a groove. A second rest groove accepts the roller at the highest level (hose fully extended), and relieves the instrument of the roller weight while the dentist is using it.
