Title: Sepg. drum for dividing components of used fruit mash - has propeller blades located in the drum which cause the solid component to be conveyed automatically to a receiving vessel
Inventor: OBELE HANS
IPC: C12G1/00
Filed: 1989-12-30
Abstract: A filter drum used for sepg. the liq. and solid components of spent fruit mash is fitted at at least one end face with twisted propeller blades. A reversible drive system is used to run the drum. The axis of the drum may be at an angle to the horizontal supporting surface. USE/ADVANTAGE - For sepg. the solid from the liq. pts. of spent stone-fruit pulp of mash in the prepn. of alcoholic drinks. This sepn. is now required since environmental legislation no longer allows the disposal of the spent mash in its raw form. The proposed separator is emptied by reversing its direction of rotation after the sepg. procedure is complete, and thus causing the remaining solid component to be conveyed out of the drum by the propeller blades. This system allows the use of doors, etc. for emptying the drum to be eliminated, and the time spent in opening and closing these doors is therefore saved.

Title: Uniform heating appts. for continuous extrusions - housing is divided into several zones each fed independently by controlled heated air which leaves via common outlet
Inventor: GERLACH JUERGEN
IPC: B29C48/05
Filed: 1990-01-09
Abstract: Device for heating continuously extruded profiles consists of a housing divided into one or more successive zones linked together. Each zone has at least one inlet for the controlled inflow of warm air and at the end of the housing is a common outlet for extracting used air. Air extraction produces increasing air flow towards the outlet and increases the molecular lateral movement of air around the extrudate. The temp. diff. between air and extrudate is reduced during transversal of the working channel. Heat transfer is therefore constant or better. USE/ADVANTAGE - Uniform and rapid heating of extruded profiles during vulcanisation.

Title: Gas analyser resolving mixt. by heated catalyser wire - automatically limits concn. of resulting highly aggressive components
Inventor: MUELLER RUDOLF PROF DR
IPC: G01N33/00
Filed: 1990-02-06
Abstract: After passing through a diffusion zone, a gas mixt. for analysis is catalytically broken down with components by a heated catalytic wire, with the individual components then delivered to an electro-chemical sensor producing signals related to the concn. of each component, to be processed in a comparison circuit. To counter the highly corrosive effect of particular components, the detector signal is compared with a threshold value representing the max. desired concn. of that component, and above that threshold forms a control signal keeping the concn. of the component generally constant, e.g. by controlling the temp. of the catalytic wire, or at least the surface thereof. Such modulation may be continuous or intermittent. The diffusion zone may be a `TEFLON' membrane, and the heating wire formed of Pd and/or Pt and the detector formed as an array of individual detectors. ADVANTAGE - Analyser can dial with chlorinated hydrocarbons which form corrosive Cl2 which could shorten operative life.

Patent DE-4019187-A1 (DE)
Inventor: GONZE EUGENE VICTOR
IPC: F02B1/04
Filed: 1990-06-15
Abstract: A fuel control for an engine using a liquid fuel mixture of two fuels such as gasoline and alcohol has a fuel composition sensor and stores a fuel composition value ALC% derived from the fuel composition sensor near the end of one period of engine operation. That value is used in place of the actual fuel composition sensor output for a predetermined time IERT, e.g. 10-15 sec, at the start of the next period of engine operation. The predetermined time IERT is at least long enough for the fuel movement caused by the fuel pump to remix separated fuel in the vicinity of the fuel composition sensor and may conveniently be the period of time from the initiation of fuel pump activity until the time that fuel from the fuel tank would be expected to at least reach the fuel composition sensor. The time IERT also negates the effects of supply voltage variations during cranking, and the immediate effects of the fuel tank being refilled when the engine is stopped. <IMAGE>
