Title: Method of wrapping blocks of insulating material
Inventor: WIGFORS BO
IPC: B65B11/16
Filed: 1994-05-10
Granted: 1995-08-17
Abstract: A sufficient length of web (2) of wrapping material such as paper is drawn from a supply whereby the first end is guided with sliding action and folded up against the back of the block (1) whilst the second end during its downward movement along the back of the block is separated from the supply and stuck to the upwardly folded first end.

Title: Self-cleaning liquid filtration device, uses build up in liquid pressure to automatically raise device to surface for rinsing
Inventor: SCHULDINK HENDRIKUS EGBERT
IPC: B01D29/33
Filed: 2001-12-03
Granted: 2003-06-04
Abstract: A valve is used to build up a liquid pressure which causes the filtration device to automatically rise to the surface, where dirt accumulated on it can drop off or be rinsed off and collected.  A filter apparatus for liquids is operated whilst submerged in the liquid and is allowed to automatically rise to and/or above the surface for cleaning. Accumulated dirt on the filter (11) can then drop off or be removed by rinsing with water, so that it falls into a collection vessel (16). A magnetic valve on e.g. the water pipe can be opened or closed in order to generate sufficient water pressure to raise the filter apparatus into the cleaning position, at which point a higher pressure is created inside a cylinder (4), which is maintained at a constant pressure via a release valve and the outgoing water is used for rinsing. At the end of the cleaning step, the pressure has to be shut off for the filter apparatus to be returned to its starting position so that filtration can be recommenced with a clean filter.

Granted: 1994-07-15
Abstract: FIELD: metallurgy. SUBSTANCE: method of continuous casting of flat ingots provides for feeding metal in clearance between driven drum, side flanges and endless belt, that rounds the flanges; formation of ingot in radial direction between the drum, the belt and the side flanges; ingot reduction in the clearance between the drum and the belt in its solid-liquid state by the drum motion; drawing ingot with changeable speed; ingot unbending from radial state into horizontal state by rollers. Solid-liquid state ingot reduction up to final thickness is exercised on two sites. In the case, solid-liquid state ingot reduction is made after the ingot leaves the clearance between the drum and the belt by value of 0,1...0,6(H-h), with H - initial ingot thickness on meniscus of metal in the clearance between the drum and the endless belt, mm; h - final ingot thickness after its solid-liquid state reduction, mm; (0.1 - 0.6) - empirical factor, considering regularities of deformations of narrow flat ingots being in solid-liquid state reduction by rollers.
