Title: Falling ball viscometer for pipe systems - has inclined tube with sensors for fall time measuring system and couplings allowing fluid escape
Inventor: BRENOT PIERRE
IPC: G01N11/12
Filed: 1975-10-13
Abstract: The viscometer is of the falling ball type which is suitable for use in pipe systems. It comprises an inclined tube (3) connected at its lower end to a pipe system introducing a liquid at its upper end to a pipe system (2) which allows the liquid to escape. Two sensors (1) are positioned in the tube, at a distance from each other, and these direct the passing of a ball (21). The tube has two T-couplings (9,10), one at each end. The free end of each T-coupling is sealed so that the ball cannot pass through but the liquid can escape through the central arm of the coupling. The time taken for the ball to traverse the space between the two sensors is measured. A pump ensures that liquid flows upwards in the tube thus bringing the ball into contact with the stopper of the upper T-junction. The upward flow of liquid may be stopped without stopping the pump. This is achieved using an electro-valve in one of the pipe systems.

Title: Backwashing filter system employed on oil polluted water - using polyelectrolyte additive and recycling backwash water after flotation treatment
IPC: B03D1/02
Filed: 1977-01-25
Abstract: Purificn. of backwash water passed through a filter system employed for treating oil-polluted water is claimed. The filter system is of the type comprising granular bed percolating filter(s) upstream of biological filters. A polyelectrolyte, e.g. polyamide or cationic polyamine in soln. is injected into the backwash water which is then subjected to a flotation treatment and finally recycled through the filter system. The polyelectrolyte soln. can be added to the backwash water before and after being passed through the filters to be backwashed. The flotation system can be natural or air-assisted. Backwashing efficiency is enhanced to a degree which returns the filter system to "as-new" condition. This is mainly because the polyelectrolyte destabilises the oil emulsion formed by aerated backwash water. This emulsion previously fouled the filters despite backwashing. The polyelectrolyte further promotes flotation sepn. of hydrocarbons as an easily disposable sludge.

Title: Bale collector following baling machine - guides successive pairs of bales on alternate sides, then releases eight bales
IPC: A01D85/00
Filed: 1977-02-17
Abstract: The bale collector has bales formed in a baler passed to the bottom of an inclined guideway (6/ up which they are pushed by succeeding bales onto a second guideway (21). The first bale raises a flap (49) which locks in its up position. The second bale pushes the first rearwardly to operate a pedal (50), unlocking the flap (49) and freeing side guides (7, 8) to swing outwardly. Depending on whether a handle (17) is pivoted towards (7) or (8) the bales will pivot on it towards the opposite side and fall to bar (32). This pivots outwardly unlocking handle (17) which pivots to the other side and locks there. Guides (7, 8) are reset and the next two bales collect on the other side. When four bales are collected on each side they are released simultaneously by lowering flaps on which they rest.

Title: Micro-test plate cleaning machine - incorporates moving plate-carriage, with suction and delivery heads, which clean cavity rows successively
Inventor: COUPE NEVILLE BURTON
IPC: B01L99/00
Filed: 1977-07-13
Abstract: Plates for micro-tests or micro-titrations, contain cavities or cups, to receive small quantities of samples, arranged in rows and columns, e.g. 10 x 12 and are generally discarded after use. Before they are discarded, the samples should be extracted and the cups should eb washed to avoid contamination. Alternatively, they may be used for later experiments and should be washed beforehand. A process for cleaning a micro-test plate consists of extracting by suction the fluid in each cavity of each row, by successive rows; feeding wash liq. successively to the rows so as to fill each cavity of each row; repeating the suction and filling stages; sucking the wash liq. from the rows of cavities. An appts. for carrying out the process incorporates a carriage to support a plate mounted so as to move forwards and backward, a suction head mounted above the carriage, carrying dip tubes, equal in number of the cavities in a row, which can be lowered into the cavities while the carriage is stationary; a wash liquor container with feeds corresp. in number to the cavities in a row, to feed them while the carriage is stationary. Appts. may be operated manually or automatically. The control circuit can be readily adapted to fill the cups with specific quantities of reactants after they have been completely washed.
