Title: Two-stroke diesel engines with opposing free pistons and buffer chambers
Inventor: WAGNER ALBERT
IPC: F02B75/02
Filed: 1986-08-11
Abstract: In these engines, with complete balancing of masses in each cylinder and low heat losses in the combustion, the free pistons 2, with low friction losses, are subjected to acceleration and deceleration solely by the pressures of the compressed air or of the gas in the cylinders 1 or in the buffer chambers P. In addition to the known direct drive of the pump pistons of a hydraulic pump, the free pistons 2 can drive two free wheel shafts 30 running in rolling-contact bearings with low friction losses by way of piston rods 4, geared racks 35 and gears 31 with clamping body 32.   In two-cylinder and four-cylinder engines the injection pumps 10 driven by compression air are controlled by the gas pressures of the first pair of cylinders so that the injection intervals are virtually uniform. Moreover, in each buffer chamber the buffer charge with a buffer-charge slide valve 50 is controlled by the gas pressure of the cylinder, so that the two free pistons have constant running due to the same buffer pressure in both buffer chambers. In addition, as the buffer pressure rises, the buffer charge pressure is increased as a function of the piston speed by compressed air entering by way of the buffer charge control unit 55, so that the buffer pressure does not become too great. <IMAGE>

Title: Window-cleaning system, in particular for motor vehicles
Inventor: ABERSFELDER GUENTER DR RER NAT
IPC: B60S1/48
Filed: 1987-10-09
Abstract: In the case of window-cleaning systems the cold resistance is improved by the addition of antifreeze. In order to ensure reliability of operation even at low temperatures, a high concentration of antifreeze has to be employed. This liquid mixture is, however, also consumed at higher temperatures which increases the running costs and reduces the washing efficiency. The intention is for it to be possible to use the novel window-cleaning system in all temperature ranges and for it only to consume the necessary amount of antifreeze. In the novel window-cleaning system the liquid mixture is matched to the particular outside temperature by virtue of the controlled addition of antifreeze, the mixture ratio being monitored by a densimeter. In one embodiment of the invention, the reservoir (1) is divided into a washer fluid chamber (2), an antifreeze chamber (3) and a mixing chamber (4). The window-cleaning system is intended for use in motor vehicles. <IMAGE>

Filed: 1988-01-26
Abstract: In the case of the electrical switch according to the invention, rivet-like contacts are used which are located in the switch housing at one end and project out of the switch housing at the other end. The rivets have a bend in the region of the underneath of the housing. In consequence, the free end of the lower contact region is eccentric with respect to a centre line which is given by the rivet-like contact located in the inner housing. In the case of the method according to the invention for producing a switch, those contact regions which project out of the housing can be bent at the same time into a plurality of contact rows, so that the free contact end is not on the centre line of the rivet-like contact region located inside the housing. The device according to the invention for carrying out a method provides a die which bends all those contact ends which project out of the switch. A template is provided for twisting the contact regions which project out of the switch.
