IPC: C07C215/32
Filed: 1972-07-07
Abstract: Process for the manufacture of N-(2-halogenoethyl)-N-(2-hydroxy-2-phenylethyl)amines, known intermediates in manufacture of the anthelmintic tetramisole. In one alternative, process comprises reacting N-(2-hydroxyethyl)-N-(2-hydroxy-2-phenylethyl)amine with a halogenating agent, e.g., thionyl chloride, to give N-(2-halogenoethyl)-N-(2-halogeno-2-phenylethyl)amine salt, and reacting latter compound with water to give said monohalogeno compound. In another alternative, the isomeric N-(2-hydroxyethyl)-N-(2-hydroxy-1-phenylethyl)amine is reacted with halogenating agent to give N-(2-halogenoethyl)-N-(2-halogeno-1-phenylethyl)amine derivative, and reaction of latter with water gives said monohalogeno derivative. In another alternative, a mixture of the two said dihydroxy compounds is used as starting material. Conversion of the two dihalogeno derivatives to the same monohalogeno derivative proceeds, apart from exceptional circumstance, via an aziridine derivative.

Title: Mechanical sweeper with friction disc drive - has discs for brush and machine movement driven by disc powered by motor
IPC: A47L11/24
Filed: 1973-04-03

Title: Prefabrication of concrete sectionalised buildings - pouring with front wall horizontal to improve speed and simplify formwork
IPC: B28B7/22
Filed: 1974-06-27
Abstract: Improvements to the techniques for prefabricating three-dimensional sectionalised buildings of standard dimensions, using blocks consisting of a floor slab with at least one vertical wall and a ceiling slab which is cast separately and fixed to the block. The blocks are made by using a mould into which concrete is poured, the front of the block being placed in a horizontal position so that the floor slab is vertical. When the concrete has hardened, the block is swung into its normal position and the mould removed. The block is placed in this position because the front contains openings and may also require a special finish. This technique is fast and does not require a large amount of complex moulding equipment.

Title: Geothermal well sinking system - inserts plastics tube into hole and fills up surrounding annular space inside walls
IPC: E21B43/10
Filed: 1976-07-09
Abstract: The geothermal well sinking system consists of drilling down to the desired depth and lining the well as necessary. A tube of plastics closed at the bottom, is lowered into the well, there being a clearance between (17) and the walls (1) of the latter or the metal lining (3). After removal of the lining, the intervening annular space between tube and walls is filled up, to give the necessary thermal contact. This can typically be effected by the collapse of the surrounding earth against the tube. Alternatively, the well can be drilled into underground water, which fills up the space concerned, or the latter can be backfilled with the soil excavated or injected with mud, water etc.

Title: Single cell proteins by aerobic fermentation - in serpentine horizontal tubes with integral cooling heat exchanger
Inventor: HAWKINS HAROLD MILLS
IPC: C12N1/32
Filed: 1976-09-16
Abstract: A fluid is pumped through a serpentine system of generally horizontal tubes provided with an integral heat exchanger. Oxygen is injected at the upstream end of the tube system and fermentation takes place while the resultant heat is removed by the heat exchanger. A vertical tank contg. horizontal trays receives the output from the tubes and allows gas to escape escape from the liq. which is recycled to the tube system. Pref. a foam separating vessel is used to recover liq. prod. from the tank. The appts. is used in the prodn. of single cell protein by the aerobic fermentation of microorganisms using methanol as the feedstock. The use of an integral heat exchanger presents a large surface area to the fermenting liq. for heat removal.
