Patent DE-4100377-A1 (DE)
Inventor: REP ANTON
IPC: G09F15/00
Filed: 1991-01-09
Abstract: Individual frame profiles (1, 21, 27, 30, 34) can be braced against one another to form an exchangeable frame by means of a bistable spring clamping element (9). An exchangeable frame of this type has at least two separation joints (10) which are arranged at opposite points on the frame, each have at least one bistable spring clamping element and thus allow rapid opening or closing of the separation joint (10). For the purpose of guidance, the frame profile has two inwardly directed, plate-type projections (2, 3) which are arranged parallel to the picture plane. The space between these projections (2, 3) serves as a guide space (12) in which a plate-type guide part (6) is arranged movably towards at least one side of the frame. Located in the movable side of the guide part is a connecting link cutout (7) which is designed in terms of shape such that a power accumulator (8) is mounted by one end (23b) so as to be axially rotatable in a counter bearing (19) while the other end (23a) is arranged so as to be displaceable along the path (16) of the connecting link from one of the two power accumulator end positions (15b) to the other (15a) or vice versa, the separation joint (10) being held in the closed position (15a) under a prestress of the power accumulator (8). The power accumulator (8) and frame profile projections (2, 3), connected to one another by a connecting pin (13), together with the guide part (6) and the connecting link cutout (7) arranged therein form the bistable spring clamping element (9). <IMAGE>

Filed: 1991-03-22
Abstract: The inlet to and outlet from a hydraulic reaction chamber (10) incorporate two variable constrictions (14,16) and a single valve (20) operated by an electromagnet (22) to increase the size of one constriction as the other is reduced. The rod (24) coupled to the electromagnet (22) is opposed by a pressure piston (26) to which hydraulic pressure above a predetermined max. is applied to repel the valve (20) and reduce the cross-section of the inlet (8). ADVANTAGE - Reaction pressure under heavy loading in upper speed range is reduced to give perceptibly lighter feel to steering.

Title: Computer control for precision winding of cheese packages - using parameters which depend only on bare tube dia.
Inventor: EIBEL JOACHIM DR ING
IPC: B65H54/42
Filed: 1991-04-19
Abstract: A precision cheese package (Sp) is wound with a surface drive (Aw) and a traverse (V) controlled by a computer (R) so that the package speed (eta Sp) and the package dia. (alpha Sp) and the empty package tube dia. (alpha Sp) are related by the relationship (I) where K is a constant. When a stored dia. value (e.g. alpha 1) is reached, the next winding stage is switched in. Pref. the number of yarn cross-overs (Mn) of a winding stage with a chosen tolerance (alpha 1, alpha 2) on the selected crossing angle (alpha), starting from an initial cross-over value (Mo) for the empty tube, is given by the relationship (II), where n = 0, 1, 2, etc. (number of winding stages) i.e. integers, and is stored in the computer. The corresp. package diameters (alpha Sp) given by the relationship (III), where n = 0, 1, 2, 3 etc. (number of winding stages, i.e. integers), are also stored. The calculated package diameter (alpha Sp) is used to select the correction value (K(m)) which is proportional to the cross-over (Mn) for the speed (Nv) of the traverse motor (Mv). USE/ADVANTAGE - Computer control of precision winders is improved which does not depend on yarn parameters.

Title: Soil gas sampling and on-site analysis - using combined probe and drill tubing with internal packer system
Inventor: HEIDRICH KARL DR
IPC: G01N1/22
Filed: 1991-06-20
Abstract: Rapid, interference-free sampling of soil gases and on-site determination of BTX, halocarbons and permanent gases (O2,CH4, CO2 and N2) is carried out by use of a soil gas probe with an internal packer system which prevents gas leakage until measurement and which allows profile measurement over the entire depth in one operation. The on-site analysis equipment includes a photo-ionisation detector for determining gas equilibrium, a capillary gas chromatograph with a miniature thermal conductivity detector, and opt. a computer (e.g. a laptop) for storing the measurement data. ADVANTAGE - The probe cna be combined with an external drill tube in which the internal packer system allows gas entry only to the probe region so that a complete gas profile can be obtained.  Interference by air entry on replacing a drill tube by the probe is thus avoided and the drill tube can be left in-situ for permanent gas measurement.

IPC: F23C9/00
Filed: 1992-03-21
Abstract: A burner for generating hot gasses has a burner pipe (10) that comprises a support pipe (12) linked to a heating tube (14) with a nozzle (28) arranged in the support pipe which ejects a jet of fuel (36). A diaphragm (18) that separates inside the burner pipe a pre-chamber (16) from a combustion chamber (20) has a central bore (38) through which passes the jet of fuel.
