Title: Water trap for engine intake or exhaust - with two 180 degree lips surrounded by a collecting chamber
Inventor: BUHMANN RUDOLF
IPC: B01D45/04
Filed: 1976-10-08
Abstract: A gas flow duct has two inwardly projecting lips at 180 degrees to each other, surrounded by an outer chamber. It is used as a water trap for gas flow lines, such as engine air intake or exhaust ducts. This simple construction avoids the need for flap valves or cowls for the prevention of e.g. rain water ingress. Two lips are formed in the pipe duct by making angled saw cuts and then pressing the wall inwards at each point so that the lip formed covers practically the whole cross-section of the duct. The two lips are at 180 degrees to each other. A circular chamber surrounds the pipe at this point and is crimped to it at each end. The flowing gas is directed outwards by the first lip, into the chamber, and then back again into the pipe at the second lip. Any water is trapped in the outer chamber and can be run out by suitable connections, which may be through the folds of the crimped sections.

Patent DE-2754179-A1 (DE)
Inventor: PFLAUM AUGUST
IPC: B41F13/58
Filed: 1977-12-06
Abstract: Web sections (1) which come to lie one above the other in the free edge region can, due to friction, carry electrical charges of the same polarity and, due to mutual repulsion, can disturb further processing and, for example, fold over. The mutual repulsion can be eliminated by discharging (6); nevertheless the free edge regions can tend to flutter, wrinkle and fold over. Now, the free longitudinal edge regions, facing one another, of the web sections (1) coming to lie one above the other are electrically charged but with opposite polarity, so that the longitudinal edge regions adhere to one another. These charges can be applied intermittently along the longitudinal edges, so that adhesion points (9) are provided which are disposed with spacing from one another and expediently at the points of the web section ends. The charging can take place by means of web deflector rolls (2, 3) bearing electrodes which serve to charge section by section. <IMAGE>
Patent DE-2754504-A1 (DE)
Inventor: UEBEL HELMUT DIPL ING
IPC: B61L23/00
Filed: 1977-12-07
Abstract: The influence of unfavourable friction conditions between rail and wheel on the operation of rail vehicles which are controlled automatically from a fixed control point (OFS) and perform target braking operations after bends requiring braking, which operations are calculated from the speed of the vehicle, the distance from the target and a brake deceleration predetermined by the control point, is to be reduced. For this purpose, sensing devices (F1...Fn) on the vehicles report to a computer system (R), via data connections (D), slip and skid processes which have been detected. These processes are stored in counters (Z1...Zm) assigned to individual routes. During the calculation of the bends requiring braking, the computer system interrogates these counters via selection circuits (AS1...ASm) and takes into account the interrogated values for the determination of the braking deceleration which can be achieved. This permits better utilisation of the friction values and a higher degree of security when stopping at the target. <IMAGE>
