Title: Controlling seam quality in welding thermoplastic sheet - by constantly measuring roller pressure, comparing with set value using computer, and adjusting roller speed accordingly
Inventor: GRELLER PETER
IPC: B29C65/20
Filed: 1992-09-16
Abstract: A method is claimed for controlling a process for welding together thermoplastic strips (I) using a welding machine with a welding tool and 2 pressure rollers, in which the speed of the pressure rollers and any other rollers, which produces relative motion between the strips of material, is variable. The process produces a measured value representing the thickness of the welded seam, which is used as the actual value of the control variable and compared with a set value; any differences are then compensated by reducing the heat flow into (I) if the seam thickness is decreasing or increasing the heat flow if the seam thickness increases. Also claimed is a machine for the above process, with motor-driven rollers for producing relative motion between strips (I) and a spring-loaded mechanism (15) for adjusting the roller pressure. Mechanism (15) is fitted with a load sensor (37) for measuring the force exerted on material strips (F1, F2) by pressure rollers (7,13); sensor (37) is connected to one input of a computer (34), which compares the actual value (F1) supplied by (37) with a set value (F8) from another input and produces an adjustment signal for motor (22) depending on the result of the comparison. USE/ADVANTAGE - The invention provides a simple but reliable method for producing high-quality seams when welding sheets of thermoplastic material together, esp. w.r.t. to controlling the relationship between seam thickness and total material thickness.

Abstract: Scraper installations have a central mixing unit (MA) around which circle-sector-shaped boxes (B1, B2, ...B5) with batchers are arranged. The boxes (B1, B2, ...B5) accommodate a supply of sand and/or gravel, which is moved by means of a bucket (K). To this end, the bucket (K) is guided by a haulage rope and a return rope on a scraping arm (SA) which can be swivelled across the boxes (B1...B5). Motors, rope drums, a ring gear, position sensors and a central control unit are provided for moving the ropes and the scraping arm (SA). In a learning phase, the number of stowing positions (V1, V2...V9) of the bucket (K) is preselected as a function of the size of the boxes (B1...B5) and the material lodged in them. Then, by means of manual control, the bucket (K) is moved in each stowing position (V1...V9) between the bottom starting position, the normal top target position and the maximum possible top end position. The corresponding positions of the rope drums, measured by means of absolute-angle encoders, are stored as desired values. The number of supply strokes of the bucket (K) is then selected. During operation, the position of the scraping arm (SA) and the position of the bucket (K) are constantly measured by means of the absolute-angle encoders and compared with the stored desired values, the entire installation being continuously monitored for faults and defects. The scraper installation can thereby work fully automatically and in addition ...   Original abstract incomplete. <IMAGE>

Title: Process for the separation of polyol esters of differing degrees of esterification
Inventor: GUTSCHE BERNHARD
IPC: C07H13/06
Filed: 1993-10-18
Abstract: Process for the separation of polyol esters of differing degrees of esterification, the separation into fractions having differing concentrations of polyol esters of a differing degree of esterification being carried out by means of a chromatographic process, the polyol esters preferably being sucrose esters, in particular sucrose laurates. The process is also applicable to fatty acid esters, in particular esters of pentaerythritol, of trimethylolpropane or of glycerol. The process particularly conveys advantages if the polyol esters of differing degrees of esterification, after separation of a fraction of a specific degree of esterification, form new esters of this degree of esterification again in an equilibrium reaction and, in a subsequent separation step and/or by feeding back to the inlet, the newly formed esters of this degree of esterification are also separated off.

Title: Capacitance measurement circuit esp. for tank level sensor of e.g. motor vehicle
Inventor: WILFERT THOMAS DIPL ING
IPC: G01R27/26
Filed: 1994-05-25
Abstract: The capacitance measurement circuit has two main blocks : a timer or astable multivibrator circuit (11) and a capacitance-multiplying circuit (10), where the ratio of resistance values (R1,R3) determines the multiplication ratio. The capacitance being measured, which forms a level sensor, has a constant capacitance (CO) and a variable (CM) capacitance component. The timer involves an integrated circuit (IC2) with input via two resistors connected to the capacitance, with its output connected to an inverter (IC3) with a further resistor (R5) connected to the supply (UV). The capacitance is measured by evaluating the timer frequency, where tiny change in the capacitance results in a large frequency change.

Title: Method for removing or depositing material by means of a particle beam and device for carrying out the method
Inventor: TALBOT CHRISTOPHER GRAHAM
IPC: H01J37/305
Filed: 1994-06-20
Abstract: Preferred etching during the removal by means of a focused ion beam can lead to a rough surface with holes and can make it difficult to carry out measurements and repairs on integrated circuits. Preferred etching is compensated by obtaining a contrast image of the partially removed workpiece, by producing mask-visualisation data from the contrast-image formation and by controlling the further removal by using the mask-visualisation data. If, for example, a window has to be sunk into a top-layer supply plane of an integrated circuit in order to expose a hidden layer, the window is incorporated partially. An ion-beam image is obtained and matched to threshold values for the purpose of producing mask-visualisation data. The mask-visualisation data discriminate between surface regions where there is a breakdown in the supply plane and those which do not as yet have a breakdown. The removal is resumed using the mask-visualisation data for controlling the effective ion-beam removal current. The mask-visualisation data are refreshed periodically as the breakdown of the window proceeds.
