Title: Cylinder head for IC engine - has lubricant chamber in camshaft bearing and connected to cam lubrication channels
Inventor: ZINNECKER FRANZ
IPC: F01M9/10
Filed: 1977-01-28
Abstract: The i.c. engine cylinder head houses camshafts whose bearings have radial lubricant channels. The wall of the cylinder head has an axial chamber for collecting lubricant adjacent to the bearing. The lubricant collecting chamber (5) is connected to a lubricant channel (6) leading to cams (8). The lubricant is guided from the chamber to the cams which have radial lubricant outlets (7). Part of the lubricant which is used for camshaft lubrication is subsequently used for cam lubrication. Hence, it is necessary only to supply oil for camshaft bearing lubrication.

Title: Separator for liquid extraction processes - having interface run=off via horizontal slot giving constant interface level if phase densities vary
Inventor: MUELLER ECKART DR
IPC: B01D11/04
Filed: 1977-07-05
Abstract: Liquid extraction process uses the mixer-separator principle with varying flows and competitions in the feed. On the side of the separator from which the sepd. phases leave, there is located a vertical plate to seal the end, having a horizontal slot at the level at which it is required to control the phase interface. The cross section of this slot is dimensioned so that the liquids can flow through without significant pressure loss. Upstream of this is mounted a further vertical plate which has upper and lower flow passages for the sepd. phases. The slot level then determines the level of the interface between the two phases in the space behind the outlet plate. Used for liquid-liquid extraction processes esp. experimental ones where variations can occur in flow, compsn. and density of the feed. Existing florentine type separators are subject to variation in interface level with such changes. The separator described maintains the level within very narrow limits.

Title: Camouflage netting spray station - uses a polygonal reel or drum to present netting to a spraying platform
Inventor: OELLERKING WILLI
IPC: B05B13/02
Filed: 1977-09-28
Abstract: The equipment to stretch camouflage netting and spray it on both sides with camouflage colours uses a rotary reel or drum in the form of a regular polygon.

Title: Combined plate and insertion folding machine - is half length of longest piece of linen and folds more quickly
Inventor: GEIGER FRIEDRICH
IPC: B65H45/04
Filed: 1978-06-01
Abstract: The forward motion of a piece of linen on a conveyor feeding an insertion folder, is represented by a series of repeated impulses proportional to the speed of the conveyor. For the folding operation, the impulses are counted between the moment when the leading edge of the piece clears a detection point, and the moment when the trailing edge of the piece crosses the detection line. During the counting operation a rolling, folding action is applied to the piece of linen on the conveyor. When the trailing edge of the piece of linen clears the detector at the inlet, the sequence of impulses is switched over so that their number is quadrupled. The impulses of the quadrupled sequence are repeated until the total of all the impulses counted reaches a preselected final value. This is equal to the number of the impulses corresp. to the length of the distance of transport, from the inlet to the folding point of the insertion folder, reduced by the number of impulses corresp. to the distance travelled by the piece of linen from the inlet until its leading edge reaches the detection point. Thereupon, the operation of insertion folding is initiated. Used for the folding of pieces of linen by insertion between two rollers. The necessary length of the folding machine is reduced to half that of the longest piece of linen, and pieces can be introduced into the machine much closer together than is possible in existing machines. The counting of impulses generated does not commence when the front edge of the piece crosses the inlet line, the final value of the count being adjusted to allow for the distance between the inlet and the detection point.
