Title: Unsatd. uronide prodn. from material contg. pectin - by anaerobic fermentation and degradation with pectate lyase
Inventor: LIEKER HEINZ-PETER DIPL CHEM
IPC: C07H3/08
Filed: 1992-07-17
Abstract: Prepn. of unsatd. uronides (I) comprises: (a) fermenting a pectin-contg. material under anerobic conditions with a bacterial culture producing pectate lyase (PL) to form polygalacturonic acid (II); (b) stopping the fermentation and removing the bacteria; and (c) allowing (II) to undergo PL-catalysed conversion to (I). The starting material comprises sugarbeet chips or potato pulp. Fermentation is at 30-40 (esp. 35) O C and pH 6-7 (esp. 6.5) for 35-40 (esp. 38) hr. Bacteria are removed by microfiltration, and the filtrate is concd. by crossflow ultrafiltration. Step (c) is carried out at 25-45 (esp. 37)OC and pH 6-9 (esp. 8) for more than 6 (esp. 24)hr. (I) are isolated by pptn. and/or chromatography. USE/ADVANTAGE - (I) are useful as medicaments for treating heavy metal intoxication (DD 268866) and as intermediates for Michael addn. reactions (EP 294879) The process gives high yields of dimer, i.e. O-(4-deoxy-L-threo -hexopyranos-4-enyluronic acid)-(1-4)-D-galacturonic acid (Ia). In an example, a mixt. of 140 litres water and 14kg pressed beet chips was inoculated with a starter culture derived from an anaerobic waste water treatment plant. After fermentation at 35degC and pH 6.5 for 38 hr, the broth was passed through a 0.2-micron filter and concd. 10-fold in a hollow-fibre unit. The concentrate (50 ml) was adjusted to pH 8 and incubated at 37 O C for 24 hr. The mixt. was worked up to give 210 mg of (Ia) with a purity of 95%.

The values are displayed and the residual imbalance determined after manual correction of the imbalance. The residual imbalance is then corrected using rotation angle dependent control values for magnet current. USE/ADVANTAGE - For rotor with controllable magnetic bearing. Quiet running achieved over long operating periods with min. maintenance costs.
Patent DE-4228359-A1 (DE)
Inventor: POTZ DETLEV DR
IPC: F02M61/08
Filed: 1992-08-26
Abstract: A fuel injection needle for internal combustion engines has a nozzle body (10) and an outwardly opening valve needle (15) with a closing head. To generate highly concentrated injection jets, the closing head (16), besides a valve cone (17) operating with a valve seat (18) on the nozzle body, has a piston (20) actuated by fuel pressure with a jacket (26) formed by a recess (25) and pierced by apertures (30, 33). The opening of the apertures is staggered axially in relation to the valve cone (17) so that the injection cross-sections which extend axially parallel, are not operated by a control edge (31) on the valve seat until after an idle stroke. An undercut (23) between the valve cone (17) and the piston (20) of the closing head ensures that the valve cone (17) lies properly on the valve seat (18).

Title: Automotive catalytic converter, preventing emission of pulse-generated noises - has heat conducting circumferential corrugated inner sleeve at outlet of mantle rim
Inventor: KUHN WILHELM DIPL ING
IPC: B01J35/04
Filed: 1992-08-26
Abstract: An automotive catalytic converter encloses the structure within a mantle which is gas-tight at the inlet end and forms a gap with the outlet structure at low exhaust temperatures. The novelty is that the housing in the vicinity of the outlet mantle rim, has a circumferential corrugated inner sleeve made of heat conducting material which opens the gap above a predetermined temp. by transferring heat to the mantle or catalyst. A suitable catalytic converter has a housing (1) in the vicinity of the outlet mantle (5) rim (7). A circumferential corrugated (13) sleeve (12) made of heat conducting material opens the gap (10) above a pre-determined temperature by transferring heat to the mantle (5) or catalyst (4). ADVANTAGE - Prevents the emission of pulse noise at the normal catalytic converter operating temperatures.

Title: Yarn tensioner - has brake roller and flanking guide rollers on a straight line for easy threading when the brake roller is lifted clear
Inventor: GUGGEMOS ADALBERT
IPC: B65H59/16
Filed: 1992-09-02
Abstract: Assembly to maintain a constant tension on a running yarn as it is drawn from its supply bobbin, either separately or as a band of yarns, is arranged so that the guide rollers (16,18) of the guide roller holder (19) are on a straight line through their centres together with the centre of the roller (17) of the brake lever (3), acting directly on the yarn (15) between them. The brake roller (17) can be lifted upwards on the brake lever (3), so that the yarn (15) can be laid over the guide rollers (16, 18). When the brake lever (3) is returned to the working position the roller (17) depresses the yarn (15) so that it follows a serpentine path through the three rollers (16,17,18), and a structured braking action is applied according to the required tension. Clearing the path by lifting the brake roller (17) clear also allows a number of yarns to be laid in place easily at the tensioning station. ADVANTAGE - The assembly simplifies the threading of the yarn through the tensioner.

Title: Apparatus for removing cross-wound bobbins from a conveyor running along a machine producing cross-wound bobbins
Inventor: REISING REINER
IPC: B65H67/06
Filed: 1993-09-27
Abstract: The object of the invention is to develop a clearing apparatus which allows both high productivity and a careful removal of the cross-wound bobbins. In the solution according to the invention, there are arranged on the conveying stage of the conveyor supporting elements, the position of which can be varied vertically under the control of a sensor monitoring the conveyor and which are each intended for at least one cross-wound bobbin. These supporting elements, in their lower position, allow the free passage of a cross-wound bobbin on the conveyor and, in their upper position, keep a grasped cross-wound bobbin out of contact with the conveyor. An advantageous design of the supporting elements is formed by rods extending in the two edge regions of the conveyor. The supporting elements are also mounted at a plurality of points on the conveyor, if appropriate so as to have a variable position. <IMAGE>

Title: Rail vehicle speed measuring device
Inventor: CRAIGIE NEIL DIPL PHYS DR
IPC: G01S7/40
Filed: 1994-03-30
Abstract: The speed of a rail vehicle is measured contactlessly using two sensor devices. The first sensor device (3) involves a radar which responds to the reflection properties of the track base. The second sensor device (4) contains at least two mutually orthogonal acceleration sensors arranged in the vertical longitudinal vehicle plane. The speed is derived from the acceleration signal resulting from the acceleration parallel to the plane of motion, taking into account the component of the Earth's acceleration projected into the plane of motion. In the event of a discontinuity in the speed signal from the first sensor device, or if it drops below a certain speed, the signal from the second sensor device is used to correct the first speed signal in the signal processor (9) giving a corrected speed signal (10).
