Title: Hand guided belt type sanding machine - has second stage of belt drive reduction driving onto reduced dia. in middle of driven roller
Inventor: PREIS ERICH
IPC: B24B23/06
Filed: 1991-02-04
Abstract: In conventional machines the two-stage belt reduction drive from the motor (11) is wholly on one side of the driven (20) and guide (24) rollers, increasing the width of the machine and moving thhe C of G to one side.

Title: Alloy pickling in mixed acid bath - using nitrogen oxide(s) emission measurement to control amidosulphonic acid addn.
Inventor: PILLMAYER KLAUS
IPC: C23G1/10
Filed: 1991-02-04
Abstract: In the pickling of highly alloyed workpieces by immersion in or passage through a mixed HNO3-HF bath contg. amidosulphonic acid, (NH2)HSO3, as NOx-acceptor, the novelty is that (i) NOx-contg. reaction fumes are extracted together with air in the suction extraction region and the NOx content of the fumes is continuously measured immediately at the fume evolution region; (ii) when the NOx content exceeds a threshold value, an amount of liq. amidosulphonic acid, corresponding to the excess, is added to the bath; and (iii) the procedure is repeated when either the threshold value is again exceeded or, after a predetermined time after ending the addn., the actual measured NOx value still exceeds the threshold  value. Appts. for carrying out the process is also claimed. USE/ADVANTAGE - The process is useful in the pickling of  austenitic (-ferritic) steel and Ni (alloy) sheet, tube or rod.  It maintains NOx emission below a preset threshold value in a simple and space-saving manner, while allowing continuous rapid pickling.

IPC: A01B73/04
Filed: 1991-03-04
Abstract: The invention relates to a rotary mower having a plurality of mowing rotors which rotate in a common horizontal plane during work. In this position, the mowing rotors have a specific working width. To obtain a transport width smaller than the working width, the outer mowing rotors (2') are arranged on auxiliary frames (9) which are so connected movably to a machine frame (1) that they can be displaced out of their position in a common horizontal plane, so that the outer mowing plates (4) reach near to the cylindrical casings (3) of the inner mowing rotors (2). For this purpose, the auxiliary frames (9) can be connected to the machine frame (1) by means of links (7, 8) or also by means of cam guides. <IMAGE>

The frame closely surrounds the base plate at its edges where it has C- or L-shaped profile, and the membrane has a thickened edge section in this area. The clearance between the base plate and the edges of the frame is greater than the thickness of the membrane, but less than the thickness of the membrane's thickened edge section. USE/ADVANTAGE - Used for introducing gas into aq. suspensions, and esp. for aerating waste water. The oxygen transfer, the air distribution and the performance during switching on and off are improved, while at the same time the pressure drop and the tendency to blockage are reduced

Abstract: PCT No. PCT/EP93/01421 Sec. 371 Date Feb. 17, 1995 Sec. 102(e) Date Feb. 17, 1995 PCT Filed Jun. 4, 1993 PCT Pub. No. WO93/25946 PCT Pub. Date Dec. 23, 1993The process has an open control loop which detects the total current intensity of actuators and supplies it to a microprocessor. In a modulation mode the microprocessor successively generates at its output a modulated set value signal for each actuator, the set value signals lying below the response level of the process. The microprocessor then determines compensation values from the total current signal with which the set values of the actuators are corrected. The (regulating) speed of a control is thus combined with the accuracy of a regulation. The hardware expenditure (costs) is minimized thanks to the total current detection instead of the individual current detection.

Patent DE-4226209-A1 (DE)
Inventor: SCHMALZL DIETER
IPC: H05K9/00
Filed: 1992-08-07
Abstract: The invention relates to a single contact spring, especially for the RF screening of electronic devices for engagement in sheet-metal apertures. So far such springs have been engaged in sheet-metal apertures of various sections by complicated sequences of movements in such a way that ejection through mechanical stresses have been permanently prevented by positive engagement. Here it is often difficult to locate them in the assembly holes. To eliminate this drawback, in a first embodiment of the invention the single contact spring consists of an engagement cage (14) and a sprung contact component (2) in the form of a contact cup (6). The engagement cage (1) is trough-shaped and its lower part is trapezoidal in cross-section, open at both frontal sides and has two opposite recesses (16) in the two long sides. The upper edge of the long side is angled outwards and the contact cup (6) is held via an angled, sprung bearer component (14) secured to the frontal sides. The advantage of this spring is that it can be fitted in one direction and compressed from the sides. The contact cup can also be roof-shaped in a further embodiment.
