Title: Crankpin machining using milling machine - has cutter moved in relation to rotating crankshaft to reduce cutting force
Inventor: TSUKIJI YOSHIHIRO
IPC: B23B5/18
Filed: 1977-01-27
Abstract: To machine the crankpin (2) of a crankshaft, the crankshaft is rotated about its own axis. At the same time a milling cutter (3) which is rotating in the opposite direction to the crankshaft is moved towards the crankpin so that the tip circle of the cutter teeth (3a) rolls around the crankpin (2). This combined rolling and rotation of the cutter reduces the force exerted on the cutter teeth because the depth of cut is a min. at the beginning of the working phase for each tooth. This reduction of cutting force enables a much higher cutting speed to be used with a consequent reduction of machining time.

Title: Removing chloroprene impurities from ethylene di:chloride streams - by chlorination to high boiling prods. and distilling
Inventor: SMALLEY EDMUND W
IPC: C07C17/38
Filed: 1977-10-22
Abstract: Ethylene dichloride (I) is recovered from a stream contg., (I), (alpha)-chloroprene impurities boiling below the b.pt., of (I) and impurities boiling above the b.pt., of (I) by passing the stream to a first distillation zone to give a first distillate contg. low boiling impurities and a tail prod. (I) and the high boiling impurities. The first tail prod. is sent to a second distillation zone to give a second distillate contg. (I) and a second tail prod. contg. high boiling impurities. The improvement comprises chlorinating the chloroprene impurities by introducing into the first distillation zone, during the distillation of (I), a gas contg. elementary Cl, to produce chloroprene reaction prods. boiling above the b.pt. of (I). These reaction prods. are then removed together with the first tail prod. and passed to the second distillation zone. In the prepn. of vinyl chloride by cracking (I), unconverted (I) which is recycled contains chloroprene impurities which cause coke formation. The above process enables these impurities to be removed as chlorinated hydrocarbons which may be recovered and used for prepg. organic solvents.

Title: Tile colour grading appts. - has colour sensors operating switches at transfer table between conveyors and handling devices
Inventor: COSTANTINI ANTONIO
IPC: B07C5/36
Filed: 1978-03-07
Abstract: The grading machine for classifying the colour of tiles has interconnected grading tables (1) onto which the tiles (3) are passed by a conveyor belt (2) which runs on a lower plane onto a flat platform which can be moved vertically up to the level of the table (1). As soon as this platform reaches the table a slide member (6) is actuated to push the row of tiles onto the table which has a magnetic switch underneath which through a relay system provides each tile with an electric signal corresponding to its colour. These signals can then be evaluated in comparison with another signal emitted by the basic shade and the tiles can thus be sorted out. A new intake of tiles arriving from the conveyor belt pushes the first row along to the side outlet end of the table where they move onto a further table level (7) which can be brought vertically down to the level of the discharge conveyor belt (8).

Patent DE-2823364-A1 (DE)
Title: Roller device for working plate material with ferromagnetic powder - has uniform distribution of powder due to uniform magnetic flux density (OE 15.6.79)
Inventor: SCHICHIREV BORIS NIKOLAEVITSCH
IPC: B24B1/00
Filed: 1978-05-29
Abstract: Plate material is worked by passing it through the gap between two rollers constructed from a magnetically permeable material and incorporating induction elements for the creation and maintenance of a magnetic flux which holds a ferromagnetic powder on the surface of the rollers. The installation is further equipped with a means for evenly distributing the ferromagnetic powder across the surface of the roller so that the plate material is uniformly treated. To achieve the even distribution of the powder, it is necessary to eliminate the end effect where the magnetic flux, due to the close proximity of the induction device, is stronger. This is done by increasing the air gap over the affected end zone, pref. by constructing the rollers so that the edge zone is tapered. Alternatively, the mounting for the rollers may incorporate blades, principally parallel to the rollers but with a curved, concave edge so that the gap between the rollers and the blade edge is greatest where the flux density is least.
