Title: Cutting tool with modular teeth - has narrow teeth relatively offset across width to reduce power consumption
IPC: B23D43/02
Filed: 1974-09-09
Abstract: The overall width of the module (15) is equal to the width (W) of the cutting edges of the conventional cutting tool for given feed per cutting tool. The cutting edges of the module are such that two cutting edges of the multiple module are arranged neither parallel nor at right angles to the direction of the relative movement of the workpiece (14). The width of each cutting edge is reduced to a fraction of its total width and the feed per tooth is increased. This is equal to the specified number of cutting edges so that the cross section area of a chip cut (14") has the same width as the total width of the cutting edges.

Title: Contact plate for mass transfer columns - esp distn., rectification and absorption columns working under vacuum
IPC: B01D3/16
Filed: 1974-09-10
Abstract: On a contact plate for mass transfer equipment, having openings through which a gas can flow covered by valves (cover-plates) fitted with means to limit their movement, the part of the valves covering the openings extends from the openings and are curved so that they have a cylindrical form in cross-section. The convex side of the curved surface is turned towards the plate so that the valves begin to open by rolling of the surface over the plate. The closing moment on the valve increases as it opens, so that stable operation over a wide range of loadings is achieved. The valve has a low press. loss in the just-open as well as the fully open position, making it suitable for operations carried out under vacuum.
