Title: Prepn. of 2,5-di:keto-gluconic acid - using a continuous fermentative oxidn. of glucose, useful as starting material for the formation of ascorbic acid
Inventor: MEYER JOACHIM DR
IPC: C12P7/58
Filed: 1992-11-19
Abstract: Prepn. of 2,5-diketo-gluconic acid (2,5-DGA) comprises fermentive oxidn. in the presence of oxygen by (a) synthesising 2,5-DGA from glucose in a main reactor and by (b) further oxidn. of (a) to form more 2,5-DGA in a subsequent reactor without the addn. of fresh glucose until no substantial quantities of 2-keto-D-gulonic acid and/or gluconic acid are present in the end prod.. Pref. the continuous fermentive oxidn. is with Erwinia in a main reactor contg. 100 to 400g glucose/l. The pref. exchange rate is 0.05 to 0.5 litre and hour more pref. 0.1 to 0.2 litre an hour. USE/ADVANTAGE - 2,5-DGA is a precursor of 2-keto-L-gulonic acid which can be rearranged to form ascorbic acid. Currently, only batch processes have been described for the formation of 2,5-DGA. The new method is a continuous process that is faster and needs less space than known methods, and a pure prod. can be produced. In contrast to prior art methods, with a reactor in series (b), the side prod. formation of gluconic acids and 2-keto-D-gluconic acid can be avoided.

Patent DE-4243391-A1 (DE)
Inventor: MUELLER ROMAN
IPC: B02B1/06
Filed: 1992-12-21
Abstract: The novel invention proposes to moisten e.g. grain by generating a fluidised bed (20) in a moistening chamber (2) by means of accelerating rotors (3). To this end the cross-section of the swirl chamber is shaped into an outer boundary surface of two or preferably three accelerating rotors (3, 3', 3''). In this manner, the fluidised bed is given an out-of-round cycle and a spiral movement in the moistening chamber (2). Moistening is very carefully performed so that the grains undergo virtually no friction and breakage. Further advantages include a longer and more controllable effective time during moistening, optimal grinding preparation and shorter, controllable conditioning time.

Title: Clamping device for feelers
Inventor: HASENSTAB WERNER
IPC: B23Q11/00
Filed: 1993-03-06
Abstract: The present invention describes a tool holder which constitutes an exact tool receptacle which is adjustable after misalignment and can be optimised in its properties also in terms of the cutting force or natural frequency of the system. The aim of the invention was to realise a tool receptacle which is easy to handle and can be used without problems by the user regardless of the particular type of machine tool or the drive-related design of the driven elements. Tool receptacles which are customary on the market, in the commercially available sense according to the state of the art, are not comparable either in technical design or in the geometrical dimensions with the tool receptacle according to this invention. By using the tool receptacle described here, considerably longer tool lives can be achieved and a higher production precision made possible.

Title: Method and device for the measurement of internal combustion engine exhaust gas components
Inventor: BORNEMANN TORSTEN
IPC: G01N1/22
Filed: 1993-05-28
Abstract: For this purpose, an exhaust gas measuring installation is used which is provided for the measurement of diluted exhaust gases, specifically for continuous measurement. However, there is a requirement to carry out measurements on a motor test stand in which undiluted raw exhaust gas arises. The device proposed and a method which can be carried out on the same is suitable for this purpose. By this means, the range of use of gas analysers, which were originally only designed for the measurement of diluted exhaust gas, can be extended in a very simple way to quasi-undiluted exhaust gas. <IMAGE>

The control valve is regulated by the processor wrt. crankshaft position and engine timing control. The bypass can be open for a controlled phase before and/or after the valve operation, to optimise engine performance. ADVANTAGE - Improved injection control, no excess airflow, improved engine speed control. No high idling speed after warming of engine.
Patent DE-4336038-A1 (DE)
Title: Method for operating a throttle valve adjustment device
Inventor: PFALZGRAF MANFRED
IPC: B60K26/04
Filed: 1993-10-22
Abstract: A test routine is proposed for a throttle valve adjustment device, with which routine it is possible to determine whether the potentiometer (6) assigned to an actuator (3) or the potentiometer (5) assigned to the throttle valve (1) is operating correctly. If the result of a comparison of the potentiometer signals is that the throttle valve (1) is sticking at the accelerator pedal (2), the actuator is moved at least once in the closing direction and then back into the initial position at defined time intervals and it is tested whether the throttle valve (1) is "following the movement". If this is the case, a fault at one of the two potentiometers is indicated and safety measures can be triggered. <IMAGE>

Title: Production line for producing rings
Inventor: MARESCH PETER DR ING
IPC: B23Q7/04
Filed: 1993-10-25
Abstract: In order to be able to carry out, in the case of a production line for producing rim rings (13), transportation from one machining station to the next with a lesser degree of outlay, along with short-cycle times, the invention proposes a transporting system in which the transportation of the rings (13) is carried out by modular transporting stations (1 to 4), and in which pivotable carrying arms (6) seize the ring (13) by means of a clamp (5) and transport them further via a common drive (9). For adaptation to different ring diameters, the carrying arms (6) and/or clamps (5) can be synchronously adjusted in height. After the ring (13) has been transferred to the next machining station, the pivotable carrying arms (6) pivot back through 180 DEG  and seize the next ring, with the result that the cycle times of the production line are extremely short and, in the event of changes to the axial spacings or the number of machining apparatuses, problem-free adaptation of the transporting system to the new conditions is possible. <IMAGE>

Title: Electrical substation (transformer substation)
Inventor: BECK RENE-ANDRE
IPC: H02B1/56
Filed: 1994-02-02
Abstract: The electrical substation comprises a chamber (2) having walls (3) which enclose a transformer and associated electrical installations (5, 6). The heat produced by the transformer is dissipated by a fan (7) which produces an air flow along the walls (3), and by a cooling circuit (11) which comprises a refrigerating unit (12) in the vicinity of the transformer and a serpentine cooling coil (15) in the wall (3), which ensure effective heat dissipation. The heat which is produced can likewise be used by an external installation (20). This arrangement allows independent cooling of the substation, the problems associated with air filtration, moisture and water ingress being avoided. <IMAGE>

Title: Automated optical weld seam testing
Inventor: BERNSTEIN JUERGEN
IPC: G06T7/00
Filed: 1994-03-11
Abstract: The weld seam testing involves use of the triangulation technique. Light strips (LP1,LP2) are applied to the surface of the component transversely w.r.t. the direction of the weld seam (3) by a light source (1) at an angle ( alpha ) of between 20 deg  and 70 deg  to the surface. The component (2,3) is moved by an automatic  handling device at a constant speed in the seam direction and with a definite orientation w.r.t. a camera (4).Images of the light strip are acquired at equal time intervals and stored in digital form in an evaluation device (11), where e.g. weld seam height (h) can be evaluated. Reference values for use in evaluating the acquired images are stored in the evaluation device before the testing process begins, and are compared with the acquired images using a vectorial evaluation matrix to generate a 'good' or 'bad' signal.

Title: Process for the manufacture of distributor caps for ignition current distributors
Inventor: SPAHN GERHARD
IPC: H01R39/60
Filed: 1986-04-11
Abstract: The invention is in the field of design technology and concerns a process for the manufacture of ignition current distributors, especially for Otto engines. The prefabricated electrodes, which already have contact surfaces and friction contacts (8) on the electrode pegs (7, 7'), as well as the central electrode for admission of current are already moulded or pressed in during injection or transfer moulding into the mantle of the distributor cap. The electrodes in the area of penetration through the mantle have a widening in several stages (9, 9', 9'', 10, 10', 10'', 11, 11', 11''). In the preferred embodiment the electrodes have a truncated cone-shaped widening, in the area adjacent to the contact surfaces, in the longitudinal section, a trapezoidal-shaped widening, which is continued at an obtuse angle in one section which continues on the side of the friction contacts, and otherwise is continued parallel to the longitudinal axis of the electrodes. In the case of electrodes with a socket-shaped cable connection, an additional widening in convex/concave form is provided for. In case of electrodes with peg-shaped cable connections, the aforementioned widening makes a jump back to this cable connection at a right angle.
