Title: Camera controlled automatic machine tool - uses pattern recognition system to identify framework of crossed lines
IPC: B23Q17/24
Filed: 1975-10-06
Abstract: The machine tool consists of, a two dimensional co-ordinate table and a tool holder whose work centre corresponds with the datum of the co-ordinates. A first system separately measures the two co-ordinates in a first position of the table and a second system takes in information for the indication of the second positions to which the table should travel and drives to generate a relative movement of the tool holder along at least one of the co-ordinates in reaction to a discrepancy signal transmitted by the systems. An optical system observes part of a working plane of the table and a third system generates an image of crossed lines, forming a framework in the work plane of the table such that the centre of the image is accurately lined up with the centre of the tool holder.

Title: Fabric take up motion on a loom - has latches controlled by beam diameter or tension, driving clutch
IPC: D03D49/20
Filed: 1976-08-16
Abstract: A regulator on the take up beam for the fabric in textile machines, esp. in looms, permits the continuous alteration of the speed of rotation. It consists of a set of driving discs and a set of driven discs arranged on the shaft of the take up beam. There are further, sets of latches for each of the driving discs. These are assembled on the main driving drum, within range of control cams coupled to a measuring device for the diameter of the fabric bale, or of the tension on the shaft, and arranged so that their engagement with the latches is variable; the basic pre-selected setting being maintained. A main handwheel is provided for adjusting the take up shaft in any position whilst the reel is being introduced or removed. Method eliminates the difficulties, inconveniences and expense of maintaining and constantly adjusting spring-loaded, hydraulic and pulley driven devices. The torsional coupling is automatically regulated as a function of the diameter of the take up beam.

Title: Hunting gun striker mechanism - has firing pin constantly thrust forward until rear end is flush with breech face
IPC: F41A19/54
Filed: 1976-11-05
Abstract: The firearm striker mechanism is particularly for hunting guns, the firing pin (1) being constantly thrust towards the muzzle end.

Title: Activated sludge protein, carbohydrate, vitamin for feedstuffs - prepd. by hot acid hydrolysis and hot alkali extn.
Inventor: BELYAEV VASILY DMITRIEVICH
IPC: C02F11/18
Filed: 1977-02-15
Abstract: Useful prods., e.g. carbohydrates, proteins, vitamins, biosynthesised in activated sludge, are prepd. by hot acid hydrolysis and/or hot alkali extn. of the sludge. Hydrolysis takes place at pH 0.01-6.0 and 80 degrees-150 degrees C. A press. of 1-5 atmos. can be used. The extracts can be used directly as nutrient media for micro-organisms or for propn. of prods. Alkaline extn. of the sludge at pH 9-13 and 40-90 degrees c is followed by sepn. of proteins at the iso-electric points at pH 3.0-4.5. Both processes can be variously combined for economy and min. waste disposal. Used in prodn. of animal feedstuffs. This gives economic disposal of surplus activated sludge from treatment of sewage and industrial wastes. It is less complication and expensive than existing methods of activated sludge disposal and gives complete destruction of pathogenic organisms and animals.
