Title: Anaerobic fermentation digester for organic matter - comprises insulated enclosure with two compartments
IPC: A01C3/02
Filed: 1975-03-24
Abstract: Anaeobic fermentation digester is intended for organic matter which has previously undergone aerobic fermentation and for the prodn. of methane. It comprises a two-compartment, insulated enclosure; the compartment only communicate at their upper portions. The material delivered by a transporter is tipped into an aerobic pre-fermentation enclosure; this has upper and lower grids where it is watered with liq. manure from a cistern; this has been pr-fermented any any excess is a turned via a pipe. Compressed air is introduced under the grids, into a hopper compartment where an active, aerobic fermentation develops. The resulting high temp. destroys most of the pathogenic germs. When pre-fermentation is complete, the material is diluted with liq. from a compartment (I). Removal of grid allows the material to descent into the upper where it is disintegrated and then introduced into the upper part of end into the hopper where it is disintegrated and then introduced into the upper part of (I) by the pump. here the hot matter becomes immersed in a (I) by the pump. Here the hot matter becomes immersed in a liq. rich in fully active ferments. A portion, assisted by a rake, overflows into a compartment joined with (I) at its top; fermentation progresses and the decomposed matter is deposited on the bottom. IT is evacuated from the base by a pump to a silo or to a spreader; new matter from (I) takes its place. Rapid and regular fermentations are obtd. while keeping the micro-organisms responsible under the best working conditions.

Title: Pipeline flow quantity limiter - has rotary cam with pinion and rack closing main valve after fixed volume passes
IPC: G05D7/01
Filed: 1976-11-04
Abstract: The contrictor is used for flow limiting in pipe line systems. There is a measuring instrument (12) before the main tap (14). Passing fluid spins the wheel (32), moving a cam (36) coupled to a wheel (42) and rack (46). Pinion movement drives a lever (24) against spring bias (30) to open the bypass valve (22). The pressure release valve (26) remains closed however. Pressure builds up in the bypass line (16) and gradually moves the piston (20) which closes the main tap (14). The flow limiter is reset when flow begins again. When a predetermined time has elapsed after reset, or after a preselected mass or volume of liquid has passed the measuring instrument (12) after the commencement of fluid flow through the system, the main tap (14) mounted within the pipeline is closed to prevent further flow.

Title: Production control system for vehicle assembly lines - uses coded parts which are scanned at each station to determine work required
IPC: B23Q41/00
Filed: 1977-01-18
Abstract: The production control system is for motor vehicle assembly lines and ensures that the features such as left- or right hand drive, automatic- or manual-transmission which have to be built in on a particular passing chassis are not omitted. In order to achieve this the body parts of the vehicle carry binary coded information in the form of holes and 'no-holes'. This information is read by a block reader constructed from a series of forked air gates (6) each provided with an air supply nozzle (8) and a measurement opening (10) separated from it by a gap (9). The coded strip is placed in the gap so that air can pass through any holes into the opening (10) following which the pneumatic signals so produced are converted into electrical signals which are amplified and used to activate and control the relevant tools on that assembly line station.
