Title: Distributor for sawn logs= - has conveyor from revolving bin supported on pneumatic tyres
IPC: B65G47/14
Filed: 1974-08-30
Abstract: The distributor has a collecting bin (2) which revolves about a vertical axis and is driven by the slewing gear (8) from the motors (6) and (7). The base of the bin is convex and the edges run on pneumatic tyres to absorb the shocks on the bin due to uneven loading. As the bin rotates, the legs are picked up by the conveyor (15) consisting of an endless belt with slats or claws to hold the logs into position. Excess logs are allowed to drop off the conveyor back into the bin for re-collection at the next turn. The speed of the conveyor is controlled independently. The logs are transferred onto a second conveyor which can swivel on the rail (37).

Title: Controlling feed and return motions of grinder - involves partial return, to relieve workpiece and grinder, before finish-grinding
IPC: B24B49/04
Filed: 1974-11-27
Abstract: Feed and return motions of the grinding wheel of a grinder are automatically controlled relative to the workpiece surface, with continuous scanning of an actual measure of the processed workpiece dimension. Grinding is stopped when a preset finished dimension is reached. Before the end of grinding, when a preset intermediate measure of the dimension is reached, the grinding wheel is set back relative to the workpiece by a preset partial return path, to relieve the workpiece and components of the grinder, and thenceforth the workpiece is finish-ground. Changeover to the fine-working phase takes place at a small value above the final dimension, so that shortened total grinding time is obtained.

Title: Gutter-end-fold fitting roof guttering base - fold incorporated in edge passing over turnover outside gutter end
IPC: E04D13/068
Filed: 1976-02-12
Abstract: The roof guttering base is designed for folding onto a gutter end, and it may be flat or part of a spherical shell, and may be shaped for folding onto a semicircular gutter or onto a box gutter. The part of the edge (2) of the gutter base (1) which is to be folded onto the end of the gutter is fitted with a fold (5). The function of this is to be thrust over an outside turnover on the gutter end, after which, together with the turned-over part of the end, it is bent round to form a simple folding fitting against the external side of the end of the gutter. The fold may be acute-angled. For a roof gutter with beading, the roof gutter base may incorporate a recess to accommodate the projecting end of the beading following the turnover of the gutter end. This is inexpensive, and is easily installed.
