Patent DE-4138336-A1 (DE)
Inventor: MEYER WOLFGANG DIPL ING
IPC: F02D31/00
Filed: 1991-11-21
Abstract: According to the invention, measures are disclosed relating to how, in a motor vehicle, the reduction/limiting of the transmission of noise from the engine can be brought about by means of its operating control and therefore how expensive engine encapsulations can be dispensed with. For this purpose, the values of different full-load lines and power-reduction lines which are at least partially different from those of the standard full-load line and power-reduction line, are stored in the free, or appropriately extended data memory capacity of the existing engine electronics (4). In addition, an electronic control device (19) which is similar in design to the engine electronics (4) is assigned to the said engine electronics (4) and compares the vehicle acceleration to be calculated with stored acceleration values and/or the sound values detected by sensors at the engine (1), if appropriate, also at the transmission (2) and other points of the engine compartment with stored sound threshold values and, in the case of the limit values for acceleration and/or sound being exceeded, outputs an instruction to a data memory selection switch (25) which then brings about a change into a correspondingly different data set (full load line and/or power-reduction line) stored in the engine electronics (4), the values of which data set are subsequently decisive for setting the injection pump for noise-reduced operation of the engine (1). <IMAGE>

Title: Warping yarn tension monitor - uses the Hall effect to give monitoring of dense yarns between creel and winder in contactless action
Inventor: BOSSARD ERWIN
IPC: B65H63/032
Filed: 1991-12-19
Abstract: Sensor to monitor yarn tension at a textile machine has a pivoting lever arm (3) which extends from its housing (6), with the free projecting end in contact with the yarn (2). The Hall probe (4) is fixed to a carrier (16). The housing is fitted to the carrier, with a release mounting. The Hall probe (4), parallel to the swing plane of the lever arm (3), is close to the permanent magnet secured to the lever arm (3). In the operating position of the lever arm, with a normally tensed yarn moving through, the permanent magnet is pref. in the operating range of the Hall probe and, when the lever arm is in the upper position through loss of yarn tension, the permanent magnet is moved out of the operating range of the Hall probe. The end of the lever arm (3) within the housing (6) is loaded by a pretensed lead spring (20), which is held in the housing (6) by a mounting (21) which can be locked in various settings to modify the spring tension. The spring holder (21) is a swing clip between two parallel housing walls which has at least one cam (23) which can engage into a number of recesses in the housing wall, in the swing range of the clip. The lever arm (3) is secured to a fork, which carried the end of the leaf spring (20) between the fork, and which swings between the parallel housing walls. The carrier (16) is a rail to take a number of Hall probes (4) and seveal housings (16). In cross section, the carrier rail (16) has a cut-back section (17), to work with a holding screw (12) at the housing (6). The Hall probe (4) is mounted to a plate (19) held in a groove (18) on the upper side of the carrier rail (16), and the plates give the electrical connections to the Hall probes. One of the two parallel walls acts as the lid for the housing (6). The housing (6) has a further opening (10), between the parallel walls, near the opening (9) for the lever arm (3). The lever arm (3) is of plastics, and the permanent magnet is embedded into the lever arm (3). ADVANTAGE - The monitor has a contactless action, using the Hall effect, and a number of monitors can be positioned in the closely packed configuration required for the dense flow of yarns from the creel to the warp winder. The monitors can also be set according to the operating conditions.

Title: Treadle for generating electric power by body strength - has DC generator with voltage control plus accumulator with multivibrators and relays to select energy source
Inventor: FOERST REINER DR ING
IPC: A63B23/04
Filed: 1992-07-10
Abstract: An arrangement for energy generation using a treadle, a DC generator with voltage control and an accumulator has a device for ascertaining the motion of the treadle, powered by an accumulator. This device triggers a monostable vibrator stage and also sets the state of a flip-flop, which can be reset by the output of the monostable multivibrator. The flip-flop activates a relay allowing the accumulator to supply power. Two other devices give signals if the switching-in speed exceeds a threshold and if the switching-out speed is below a threshold. One sets another flip-flop and the other resets it. This flip-flop controls the relay for power supply from the generator. ADVANTAGE- Sufficient power for a VDU can be generated by a "fitness fanatic" on a treadle mechanism.

Patent DE-4231333-A1 (DE)
Inventor: KUEHL HANS
IPC: F16B7/14
Filed: 1992-09-18
Abstract: A tube system for tubular constructions consists of mutually linkable tubes (12, 12', 13, 14, 39) and nodal elements ( 15, 19, 23, 28, 31, 35) slippable on the tubes so as to interconnect them. The tubes and the nodal elements are provided on the inner and/or outer surfaces of the free tube ends or free ends of the arms of the nodal elements with at least one circumferential wedging profile shaped on the one hand as a cam (5) which radially projects over an imaginary cylindrical surface (4) and on the other hand as a number of grooves (8) corresponding to the number of cams which radially deepen an imaginary cylindrical surface (7). The wedging surfaces (6, 9) of the wedging profiles substantially follow the course of a logarithmic spiral with respect to the axis (11) of the tubes or nodal elements. The slope of cooperating wedging surfaces has the same value and is so flat that when a determinable relative displacement between the tubes or the tubes and the nodal elements takes place, and the cooperating wedging surfaces contact each other, a joining pressure builds up, creating a clearance free, self-locking frictional engagement independent of direction of rotation and of stress, in the radial and axial directions, between the tubes or the tubes and the nodal elements.

Title: Process for the decontamination of soils and building rubble contaminated with heavy metals and hydrocarbons
Inventor: SCHWIDOP WOLF-DIETER DR
IPC: B09C1/08
Filed: 1993-04-16
Abstract: The microbiological degradation of organic pollutants is generally substantially inhibited by high concentrations of bioavailable heavy metals. According to the invention, in a two-stage process, this inhibition is abolished by the admixture of a fine-grained adsorbent to moist soil or building rubble. The irreversible binding of the heavy metals thus entered into no longer permits these to be bioavailable. The process can be used for the rehabilitation of material contaminated by heavy metals and hydrocarbons in such a manner that harmless filler material can be produced.
