Patent DE-3018634-A1 (DE)
Title: Mixture preparation for IC engine - with gas separator in air inlet to isolate oxygen for subsequent mixing with fuel
Inventor: VOEHRINGER KARL
IPC: F02M25/10
Filed: 1980-05-16
Abstract: The object of the fuel mixture preparation is to eliminate gases, chiefly nitrogen, which can give rise to undesirable exhaust products, and also to achieve actual gasification of the fuel-oxygen mixture before injection into the cylinders. The latter gives more complete combustion and thus also assists in less noxious exhaust emissions. Air (4) is drawn in through an inlet duct (2) and fed to a centrifugal separator (1). It is driven by an exhaust gas turbine (7). Nitrogen, having a higher molecular weight than the other gases, is expelled (12,13) to atmosphere by the centrifuge action. Oxygen passes through a duct in the centre of the centrifuge and turbine shaft (6) emerging into a feed pipe (14) to the gasifier. By passing through the turbine spindle the oxygen picks up heat so that when mixed (15) with the metered fuel the mixture more readily forms a gas instead of fine droplets in the oxygen. The carbon dioxide and rare gases which pass from the centrifuge with the oxygen play no significant part in combustion and do not contribute to the formation of undesirable emissions.

Title: Tool feed device for processing especially workpiece surfaces which run in a curved shape in the longitudinal direction
Inventor: VOIGT WERNER
IPC: B23Q35/12
Filed: 1981-02-14
Abstract: The invention relates to a supplementary application to the main patent for a tool feed device for processing especially workpiece surfaces which run in a curved shape in the longitudinal direction. Said invention has the object of achieving technologically favourable time values in the processing of three-dimensionally curved guide paths. The object of the invention is to create a supplementary device for the tool feed device of the main patent, by means of which supplementary device especially guide paths which are curved in two planes can be ground in one operation. The essence of the invention is that the required value, modified by the feed device, is supplied to the regulator of an auxiliary axis in a parallel circuit to the regulator of the main axis, corresponding to a required curvature, via an amplifier with a downstream-connected potentiometer, in order to vary the required value. The auxiliary and main axes can be interchanged with one another and a changeover between convex and concave curvature can be made by means of selector switches. The formation of the required value for the main and auxiliary axes can be derived from another axis of a moving assembly of the machine. The curved templates may have a different shape and may be arranged offset with respect to one another. <IMAGE>
