Title: Mixer-grinder for solid-liquid dispersions - with eccentric turbine mixer and scraper blade eliminating dead zones
IPC: B01F29/86
Filed: 1973-05-17
Abstract: Appts. for grinding and mixing of the type consisting of a rotating vessel and a turbine mixer driven by its own motor has the shaft of the turbine mixer arranged so that it is displaced laterally from the axis of the vessel and in addition has a vertical adjustable scraper blade placed near the vessel wall, the mixer shaft, the vessel axis and the shaft of the scraper blade being in the same vertical plane. In operation, the charge, together with a suitable quantity of grinding balls, is mixed by the turbine mixer, causing the vessels to rotate at a predetermined rate, fixed by a controlling device. When grinding is complete, the turbine motor is stopped and the vessel is rotated at high speed by its own motor, discharging the contents by centrifugal force through a sieve, fixed at the top of the vessel, which holds back the grinding balls. The eccentric turbine mixer improves rotation of the vessel and brings about better mixing and grinding, with no dead zones.

Title: In line thermoforming thin walled plastics articles - from band with cooled surface skin but hot core, avoids marks on finished product
IPC: B29C48/21
Filed: 1973-10-24
Abstract: A method of making thin-walled, thermoformed plastics objects, consists of compacting and heating the material in an extruder until flowable, extruding it through a slit-shaped die to form a band, then thermoforming the articles from the band; as the hot, plastics band leaves the die or nozzle, its surfaces are sufficiently cooled to stabilise them so that they are load bearing but still deformable, while the internal material remains substantially at extrusion temp. and still in the plastics state; in the thermoforming stage a cooled shaping tool dee-draws the band, the uncooled internal material being held between the partly cooled and hardened surfaces in the manner of a plastics filling between two shells.

Title: Curved guide roll track for continuous casting esp. of steel - provides space for coolant nozzles under mould
Inventor: BEGHIN MARCEL
IPC: B22D11/128
Filed: 1976-06-11
Abstract: Guide and support roll track for a continuous casting plant using two rows of rolls to form a curved track through which the cast billet travels; the track is divided into several sections. The axes of the first two rolls directly below the mould are located in the same plane parallel with the base of the mould, i.e. so both are at the same distance from the mould. However, the axes of the two last rolls in the first section of the track are in the same plane which includes the centre of curvature of the track. In the first section of the track, the number of rolls in the outer curved row is larger than the number of rolls used in the inner curved row. There is sufficient space below the mould to insert coolant spraying nozzles on both the inner and outer sides of the track, but the cast billet is adequately supported as it leaves the mould.
