Patent DE-4131646-A1 (DE)
Inventor: TETENBORG KONRAD
IPC: B65B59/02
Filed: 1991-09-23
Abstract: The invention relates to a method for making, filling and sealing bags from a tubular web of thermoplastic film which is preferably provided with gussets and is printed in a formatted manner, in which method the leading end of the tubular web of film in each case is provided with a transverse welding seam, a section forming an open bag is severed from the tubular web of film, the bag is then filled and the open side of the bag is closed via a transverse welding seam. To achieve the object to provide a method of this type which guarantees that the filled bags are always filled so that they are tight and taut, provision has been made for the length of the sections of web of tubular film to be varied in accordance with the filling level of the bag, for the tubular web of film to be intermittently advanced up to a printed mark once the transverse welding seam which seals the bag has been formed, for the section forming the bag to be severed by means of a separating cut without simultaneous formation of the transverse welding seam which seals the following tubular section, for the following web of tubular film to be advanced in turn through a comparatively short adjustable length, for the advanced section of the tubular web of film to be severed once again, on an optional basis, and for the transverse welding seam which seals the following tubular section to be formed.

Patent DE-4204584-A1 (DE)
Inventor: HOEHNE RAINER
IPC: B60N2/225
Filed: 1992-02-15
Abstract: In an articulated fitting for motor vehicle seats having an adjustable backrest (15), which is designed as a wobbleplate mechanism, a prestressed conical eccentric (6) that is movable in the direction of the axis of rotation runs off centre at a conical complementary area (61) of one part of the link. The eccentric (6) is rotated by means of a driving shaft (4). Both the driving shaft (4) and the eccentric (6) can freely rotate with respect to each other in both directions of rotation, starting from an initial position, and they interlock only when they have been rotated in this way over a certain angle, so that if rotation is continued the parts of the link swivel with respect to each other. The eccentric (6) is thus automatically moved back to its axial initial position by means of an axial prestress that acts thereon. The eccentric (6) is rotated in order to drive the wobbleplate mechanism only when it is in its lifted position, in which the otherwise existing and desired freedom from play of the fitting is suspended. The articulated fitting is thus very handy. As the eccentric (6) is automatically returned to its axial initial position from all swivelling positions by the axial prestress that acts thereon, the desired freedom from play and clatter is automatically restored after each actuating operation, without the need for further manipulations.

IPC: F01N3/02
Filed: 1992-03-21
Abstract: A filtering system for removing soot particles from the exhaust gas of a combustion engine, such as a diesel engine, has at least one filtering unit (6) made of porous material and comprising filtering ducts (5) in a honeycomb configuration. A resistor-heating element (1) is respectively arranged in the vicinity of the inlet aperture of the filter ducts (5), which are open on the gas inlet side, and serves several inlet apertures; the said heating element protrudes into the filter ducts as a loop and is connected via feed and discharge lines to electrical power supply. To prevent the resistor heating elements (1) from coming adrift, the surface of the filter ducts (5) and the loop-shaped heating element (1) therein are designed in such a way that their resistance to any movement of the heating loops out of the filter duct (5) is at least as great as the resistance of the loops to being pushed into the duct (5).
Patent DE-4212155-A1 (DE)
Inventor: HILL KARLHEINZ
IPC: C07H13/06
Filed: 1992-04-10
Abstract: The invention concerns a method of preparing polyol fatty-acid partial esters with a high yield of the mono-ester, in particular fatty-acid partial esters of saccharose. A polyol is reacted with fatty-acid alkyl esters in the presence of an alkaline catalyst, in the absence of solvent and without the addition of a soap, initiallly at elevated temperatures and optionally in the presence of an emulsifier, and the product thus obtained is then treated with a lower monohydric alcohol. The invention also concerns a method of reacting, in the presence of an alkaline catalyst, a polyol fatty-acid ester having a mean degree of substitution of about 2 to 8 with a monohydric alcohol to give a polyol fatty-acid partial ester with a high yield of the mono-ester, the product thus obtained then being treated with a lower monohydric alcohol.
Patent DE-4214403-A1 (DE)
Inventor: LEE JAE-HYEONG
IPC: G05F3/22
Filed: 1992-04-30
Abstract: A reference current generating circuit including a voltage generating circuit for outputting a constant voltage having resistance means MP1 and a MOS transistor MN1 between first and second voltages, and a MOS diode (MN3) and a resister (R1) connected between the constant voltage and the second voltage. Constant current is output in the amount obtained by dividing a value which is obtained by subtracting the threshold voltage of the MOS diode MN3 from the constant voltage, by the resistance value of the resister (R1). The effects of changes in threshold voltage of MN1 are substantially cancelled out by those in MN3, therefore, a reference current can be output, which is insusceptible to temperature and process changes. The threshold voltage of the MOS diode MN3 may be adjusted using a back-bias voltage difference or a second MOS diode may be added between the first MOS diode and the second voltage. <IMAGE>

Title: Selective ELISA determn. of anti-cardiolipin antibodies - which differentiates antibodies against cardiolipin-beta-2- glycoprotein-1 complex, for diagnosis of auto:immune diseases
Inventor: LAUER SABINE DR
IPC: G01N33/564
Filed: 1992-12-08
Abstract: Conventional determn. of anticardiolipin antibodies (Ab) by enzyme linked immunosorbent assay (ELISA) involves (1) immobilising cardiolipin (I) on polystyrene microtitre plates; (2) blocking residual binding sites; (3) incubation with patient sample; (4) detecting Ab-(I) with peroxidase-labelled anti-human Ab(IgG or IgM) and colour development from enzyme substrate; (5) quantifying Ab from the measured dye extinction. This method is modified to permit differentiation between Ab directed against (I) and those against the (I)/beta2-glycoprotein 1 (bGM) complex. This involves (a) after coating wells with (I) at 30 micrg/well blocking with a soln. of either 1% bovine serum albumin (BSA) and human bGP1 (50 micrg/well) or 1% BSA and 20% adult bovine serum (contg. the bovine equiv. of bGM), these solns. are also used for sample dilution; (b) removing autologous bGP1 from the sample with heparin-Sepharose and (c) subtraction of a blank value from the measured extinction. USE/ADVANTAGE - This method is used for diagnosis of autoimmune diseases (associated with presence of anti-(I) Ab). The method is specific for anti-(I) Ab, avoiding confusion with anti-complex Ab (which are associated with thrombo-embolic disorders). The correction with a blank reading accounts for non-specific binding. The method is suitable for early diagnosis.
