Title: Robotic welding unit to facilitate access - has on rotatable upper part arresting unit with lever mechanism to clamp it to conducting ring on fixed lower part
Inventor: BISIACH BRUNO
IPC: B23K37/02
Filed: 1989-11-21
Abstract: Automatic unit for industrial welding robot comprises a lower fixed part and an upper rotatable part. An automatic arresting unit on the upper part serves to stop the rotation of the upper part and simultaneously to conduct electrical current to a ring. The ring is rigidly coupled to the lower part and to effect the conduction of the current has an electric terminal fixed on it. The arresting unit has a pneumatic actuator (50) which operates a push rod (56) coupled to a kinematic lever arrangement comprising a double lever pair (60, 60'). This pair is linked at one end to the push rod (56) and at the other end to pins (64,66). USE/ADVANTAGE - Used for car body welding assemblies, the unit provides precise rotational positioning of movable parts of the robot so that entry to poorly accessible areas is facilitated. This design also limits the weight that has to be carried by the welding arm.

Title: Engine bore and stroke extension on piston underside - provides additional source of clean air to combustion chamber, causing secondary combustion and oxidation of noxious emissions
Inventor: FIRUS GUSTAV
IPC: F02B41/06
Filed: 1990-03-07
Abstract: The engine has an extended stroke with extended piston (1) and bore (8) lengths, on the underside of the piston. The induction stroke causes clean air to be drawn through the bypass channel (10) into the combustion chamber. With the piston at the top of the compression stroke, air is allowed into the resulting chamber (23) at the piston base via an inlet channel (9). Upon ignition, the piston returns, compressing the gases below it. Air is once more drawn into the cylinder via the bypass channel, causing secondary combustion of CH= and CO-emissions, which oxidise to form harmless HO and CO gases. The exhaust stroke simultaneously draw some of the exhaust gases into the base chamber (23), causing further combustion to reduce the NO=emissions. The air mixture is set via a device (25) in the bypass inlet channel connected to the injection system. ADVANTAGE - Additional regulated air flow to provide secondary combustion.

Title: Bio:mass and metabolism determn. of microorganisms - based on light reflection and of fluorescence of microorganisms
Inventor: SCHILD LORENZ DR
IPC: C12M1/34
Filed: 1990-05-19
Abstract: Biomass and the state of the metabolism of microorganism are determined quantitatively esp. as applied to the fermentation of bacteria, yeast and other cells. Light of two wavelengths is passed separately on the sample over the part of the light path for the reflection and fluorescence light. The light from the sample is subject to a separate wavelength selection and is passed to the photosensitive section. Reflection and fluorescence light from the microorganisms is measured simultaneously over long periods. The biomass is found from the reflection data by a comparison with measurements under standard conditions. A comparison of the fluorescence data and the biomass with the measured values under standard conditions determines the chromofluoro content. The state of metabolism is found in the same way. ADVANTAGE - Facilitates an automation of the fermentation of microorganisms.
