Title: Cooker hood control with photoelectric fan-motor switching - involves pulse modulation of infrared irradiation of hood-mounted detectors according to number of hotplates operational
Inventor: AVENWEDDE JOSEF
IPC: F24C15/20
Filed: 1990-12-24
Abstract: The hob (2) set into a worktop has two infrared emitters (3) near its respective back corners and a row of switches (4) alongside serving the four hotplates (5).

Title: Removing cut=out parts in case of robotic laser cutting holes in sheet metal - using gripping mandrel clamped into hole produced beforehand
Inventor: FRIEDERICHS KARL-HEINZ DIPL IN
IPC: B23K26/364
Filed: 1992-02-03
Abstract: Part cut out in the case of robotic laser cutting of holes in thin sheet metal components is removed by means of a gripping tool utilising a gripping hole in the part. This hole is produced by laser beam before the cutting-out operation begins, and the gripping tool is applied before the part is fully cut out. Cut-out part is kept in a container attached to the robot tool flange until it is deposited. Gripping mechanism has translation and rotation axes, is attached to the tool flange of the robot and has gripping mandrel with an expandable sleeve clamping the mandrel into the gripping hole. Expandable sleeve has a slit configuration which is pressed inwards by spring forces and is clamped into the gripping hole by means of a locking pin forcing the slit sleeve to expand. Alternatively, the gripping mandrel consists of spring wires whose lower ends are spread outwards by a draw bar. Cut-out part is removed from the gripping mandrel with the aid of a compressed air pulse. Container for cut-out parts is attached to the robot tool flange in such a way that without collisions it can be located below the largest cut-out part. The gripping hole is located at the centroid of the cut-out part. USE/ADVANTAGE - For mfr. of sheet metal prods. and components. Ensures high positioning accuracy of the gripping tool, requires no extra or individual programming, and ensures collision-free operation.

Title: Spinning frame - has spindle rail pressing with bevelled holes for the spindle
Inventor: STAHLECKER HANS
IPC: D01H7/10
Filed: 1992-07-09
Abstract: On a spinning frame, the spindle rail is a sheet metal pressing, suitably formed to hold a series of spindles. These are installed with suitable adjustment, into holes with an inset bevel surface, by nuts attached to the spindle housing, which have corresp. bevel surfaces, suitable for the insert surface formed in the pressing. Pref. the spindle rail is an angular pressing from sheet metal (2,3,4), which has additional features to enclose the area beneath the spindle housing (23). There are also internal structural reinforcements to obtain rigidity. The holes for the spindle to pass through are formed during the pressing process, so that the rim is angled. The locking piece on the housing (26) reflects this angle when the spindle is erected through the hole, and the top locking nut (30) has a lower surface (28) to sit in the bevel, when the spindle is aligned correctly. An additional feature of the rail, is the brake affixed to the bracket (9). The base (14) is attached to the rail (11,12). The top angle (10) restricts spindle movement by the projection (18). The brake swivels (34) to lock the spindle (17) through shoes operated by a cam handle (15). ADVANTAGE - The prodn. is economical, and adjustment for correct alignment of the spindle is inherent in the design.

Title: Process for separating out total inorganic carbon (TIC) in water, in particular waste water, and degassing element therefor
Inventor: GROEGER HELMUT
IPC: C02F1/20
Filed: 1993-03-12
Abstract: A gas is added to a defined measured amount of water, in particular waste water (effluent) which has been adjusted to a weakly acidic pH and is blown out of a blowpipe at a pressure low enough so that continuously bursting water bubbles form at the blowpipe mouth. These break the measured amount of water down into fine water particles as a result of which the escape of carbon dioxide is facilitated. The apparatus for this provides a degassing element (5) which has an expansion vessel (12). Into this there projects from the top an inflow nozzle (17) which tapers to form a blowpipe (20). On the lower side of the expansion vessel (12) there is placed an outflow nozzle (21) through which the mixture of water, gas and carbon dioxide exits. <IMAGE>
