Title: Preloaded automotive suspension bearing - has recesses in elastomer body opposite each other in transverse direction
Inventor: LANGHANS HELMUT DIPL ING
IPC: B60G7/02
Filed: 1990-03-16
Abstract: The preloaded bearing comprises an elastomer body in an outer bush, and in which a coaxial inner bush is mounted. Two recesses are formed in the body on opposite sides of the inner bush. A buffer in one of the recesses pre-loads the inner bush towards the position coaxial to the outer one. The bearing (20) is so mounted in the transverse link (16) of an automotive suspension system that the recesses in the elastomer body are opposite each other in the transverse direction. The lengthwise forces (S) acting on the wheel (12) against the travel direction (F) reduce the amount of preloading. USE/ADVANTAGE - Gives comfortable ride, while opposing steering shimmy, without hardening of the bearing under large deflection movements.

Title: Eye line of sight evaluation system - detects variation point between two signal levels for light reflected by iris and eye background
Inventor: SHINDO OSAMU
IPC: G02B7/28
Filed: 1990-12-07
Abstract: The system uses the light reflected from the eye falling on a line sensor with photoconductive bit elements. The line sensor provides a first signal level for the light reflected and a second signal for the light reflected by the background of the eye, with the variation point between the 2 signal levels determined for evaluation of the line of sight. A threshold level is set between the 2 signal levels, with detection of 2 bit elements providing outputs above or below the latter for defining a first line. A zero transition bit element is defined by the intersection of this line with the zero line and defines a second line with a lesser gradient and a third line with a greater gradient, their intersection providing the variation point. USE - For accurate measurement of line of sight.

Title: Stroke control for toggle press drive - has crankshaft driven eccentric cam drive acting through clutch to collapse toggle and disengage drive
Inventor: KLEIN RAINER DIPL ING
IPC: B30B1/00
Filed: 1991-03-13
Abstract: The press or shear has the tool slide drive (5) derived from a four-bar chain having a toggle (3, 4) which is collapsible about a hinge (16). If an upwards force is exerted on the hinge, the toggle is held straight and the drive motion is transmitted. If the hinge is broken by a downwards force, the crankshaft continues to rotate but the tool slide motion is immediately arrested. An upwards force to maintain the drive is exerted by a spring (17) through a hanger (15). The top end of the hanger is connected by an arm (14) to half (13) of a magnetic clutch (12). This is disengaged to keep the toggle straight and the slide moving to and fro. When the clutch is engaged the half (11), which is kept in oscillating motion by the crankshaft eccentric cam drive (6 to 10) causes the arm (14) to drive the hanger downwards against the spring force and 'break' the connecting rod hinge. The drive is  restored by disengaging the clutch. ADVANTAGE - Eliminates manual effort.

Title: Driving IC engine with exhaust driven turbocharger - intermittently adding extra fuel and/or air upstream of turbine with electrically-heated catalytic firing
Inventor: PIECH FERDINAND DR
IPC: F02B37/20
Filed: 1991-11-29
Abstract: An IC engine has an exhaust gas-driven turbocharger with periodic admission of extra fuel and/or air upstream of the turbine for an additional boost. This additional boost is ignited catalytically by the electrical heating of a catalyst. This occurs during while the engine is still cold or during periods of acceleration. Catalytic firing ceases above a certain critical temperature. The catalyst heating is a function of engine load and catalyst temperature. A separate pipe by-passes the catalyst between exhaust manifold and turbine. This by-pass pipe has an electrically controlled check valve. This valve also controls a third pipe leading from the manifold directly to the main exhaust catalyst box, by-passing the turbine altogether. ADVANTAGE - Simple and robust turbocharger giving reduced harmful exhaust emissions during cold engine operation and acceleration.
