RESEARCH OF MODERNIZED BD-4M HAULM SHREDDER WITH ARTICULATED KNIVES

Weiss Knives

The sharpening of microtome knives.

The regular production of a satisfactory edge on a microtome knife for the cutting of sections as thin as 2 u, which are free from scores and other blemishes, is a serious technical problem in histological laboratories. Eyen when a good edge is produced on a knife, its life is generally limited because contact with any hard material in the specimen may damage the delicate edge, causing it to sc...

The Performance of a Heavy Duty Shredder

In this paper comments and observations on the first year's performance of a new shredder at Farleigh have been set down, together with an assessment of its operating characteristics. The shredder is of recent, heavy duty design having an anvil bar and breaker section covering an arc of 85" and is driven by two motors having a combined rating of 1400 horse-power. The results of test runs taken ...

Complex Analysis of Car Shredder Light Fraction

Float fraction of float/sink process of car shredder light fraction was received from RAV (The Netherlands) in the frame of the W2Plastics (http://www.w2plastics.eu/) EU7 project (magnetic sorting and ultrasound sensor technologies for production of high purity secondary polyolefins from waste). The differently coloured plastic waste particles were manually separated and after determining the m...

A Comparison of Knives for Bread Slicing

Vertical partitioning is a crucial step in physical database design in row-oriented databases. A number of vertical partitioning algorithms have been proposed over the last three decades for a variety of niche scenarios. In principle, the underlying problem remains the same: decompose a table into one or more vertical partitions. However, it is not clear how good different vertical partitioning...
