Title: Purification of hydrogen peroxide.
Inventor: MILLAR MALCOLM HOWARD
IPC: B01J47/10
Filed: 1991-10-02
Abstract: PCT No. PCT/GB91/01700 Sec. 371 Date Apr. 2, 1993 Sec. 102(e) Date Apr. 2, 1993 PCT Filed Oct. 2, 1991 PCT Pub. No. WO92/06918 PCT Pub. Date Apr. 30, 1992.Purification of aqueous hydrogen peroxide solutions using conventional ion-exchange techniques can result in the hydrogen peroxide decomposing explosively. Much safer processes are obtained by restricting the contact between the resin bed and the hydrogen peroxide solution to a very short contact time, by employing a treatment chamber that is vented to the atmosphere and also by slurrying the resin bed. The bed is conveniently retained on a mesh that acts as a filter (13) preferably conical having an aperture (17) at its apex through which is introduced a small fraction of the solution countercurrent (10) to the main solution flow (9) in order to slurry the bed (19). The solution can be recycled through the same bed or a plurality of beds. Very high purification can be achieved and combined with improved safety of operation.

Title: Nucleic acid sensitive detection process.
Inventor: KESSLER CHRISTOPH
IPC: C12Q1/68
Filed: 1991-10-04
Abstract: A process is disclosed for specifically detecting nucleic acids in a sample. The sample is reacted with one or several labeled nucleotide triphosphates and one or several enzymes which catalyze the production of a labeled nucleic acid B containing said nucleotide. Then the sample is subjected to a non thermal denaturation and reacted with a nucleic acid probe C which is sufficiently complementary to nucleic acid B and which contains at least one immobilizable group. The possibly formed nucleic acid hybrid D is contacted with a solid phase which recognizes and binds the immobilizable group, the liquid phase is removed from the solid phase and the labeling of the solid phase is considered as a measure of the presence of nucleic acids.

Title: Spreading device for a spreading vehicle equipped with a salt spreading unit
Inventor: GEYER BERTHOLD DIPL-ING
IPC: E01C19/20
Filed: 1992-01-17
Abstract: A spreading device, consisting of an essentially vertical downpipe (3), on the lower end portion of which a motor-driven spreading plate (16) with a vertical axis of rotation (17) is arranged at the rear eccentric relative to the downpipe axis (31). To reduce or prevent the danger of damage or even destruction of the spreading device when it butts against an obstacle during reverse travel, the downpipe (3) is subdivided in its upper half into two mutually coaxial pipe parts (4, 5) which engage at least slightly in one another and which are thus connected to one another by means of a horizontal joint (6) and by means of a spring element (12). The lower pipe part (5) is resiliently pivotable in the direction of forward travel together with the spreading plate (16), and a signal transmitter (30) for acoustic and/or optical signals, which reacts during the pivoting of the lower pipe part (5), is arranged on one of the two pipe parts (4, 5). <IMAGE>

Patent EP-0519214-A1 (EP)
Inventor: JOHLIN FREDERICK C JR M D
IPC: A61B19/00
Filed: 1992-05-14
Abstract: Disclosed herein is an improved papillotome/sphincterotome procedure and a wire guide (1) which is specially suited therefor. The disclosed wire guide includes an outer insulative tube (20) of extruded teflon material, an inner shaft (30) of nitinol, and a platinum coil (40) at its distal end. The outer teflon tube has been extruded to have an internal dimension which is sized to loosely accommodate the inner shaft of nitinol with a cushion of air therebetween for additional insulative effect, and the platinum alloy coil is also loosely positioned within the teflon tubing. The nitinol material in the inner shaft has a high electrical resistivity which inhibits the flow of current, and also has superelastic characteristics which enhance the maneuverability of the guide. The nitinol shaft is tapered at its distal end where it is attached to the platinum alloy coil, which is radiopaque, allowing the tip to be readily viewed under radioscopic observation. The wire guide also has visual markings on its outer surface at 5 cm., 10 cm., 15 cm, whereby positioning can be verified endoscopically, and a marking 200 cm. from its distal end, whereby the general position of the guide relative to the endoscope can be determined by external visual observation.

IPC: H02J3/18
Filed: 1992-05-18
Abstract: The invention relates to a method and to a device for balanced (symmetrical) control of a controlled series compensation installation (2) in electrical mains power supplies (6). According to the invention, the impedance controlled variables, which are determined from current regulation, for the series compensators (14) of the installation (2), are limited, an upper limit value (Zoo) and a lower limit value (Zou) being determined by means of addition or subtraction respectively from an impedance reference controlled variable (Zo) and from a positive or negative deviation ( DELTA Z+,  DELTA Z-), the impedance reference controlled variable (Zo) being selected from the impedance controlled variables (Zy1, Zy2, Zy3). Small imbalances can thus be regulated out and unnecessary regulation excursions in the event of mains power supply defects, on one side, of short duration are avoided.

Abstract: The load control of an internal combustion engine is achieved by rotation of the camshafts assigned to the inlet valves and the exhaust valves. The inlet camshaft can be adjusted in stages between two limit positions, the exhaust camshaft can only assume two defined positions. An internal combustion engine functioning according to this method costs little to build. As a safeguard, a throttle valve, which is activated should the camshaft rotation systems fail, may also be provided in the intake duct of the internal combustion engine.

Abstract: Welding/protective helmets with visor are presently configured such that, in the event of damage to the visor by welding sparks, mechanical damage or other influences, the visor must be exchanged from the inside of the helmet with considerable outlay on labour and time. If in the case of the protective welding helmet a cassette provided with photocells is additionally installed in the helmet, said cassette must likewise be dismantled from the inside when exchanging the clear visor. The welding/protective helmet applied for here is designed such that the elastic visor is inserted from the outside (front) into guide rails with a slight outward curvature of the clear visor. The slight curvature of the clear visor stresses the latter, as a result of which the pressure on the guides and retaining rails, and thus also dustproofness are ensured, without distortions arising in the image due to the slight curvature of the visor. There is no need to dismantle a cassette provided with photocells in the protective welding helmet, because of the possibility of exchanging the visor from outside. <IMAGE>

Abstract: The invention provides a piston cylinder device as a tilting device for a vehicle with a resiliently suspended tiltable cab (3). 
     In the driving position the tilting device (5) is disengaged from the cab (3) and may resiliently move up and down. A tilting movement causes the device to be connected to the cab, said connection being locked by means of a latch hook member (12). 
     The tilting device of the invention distinguishes from the wellknown devices of this type in that the latch hook member cooperates with a lever (15), which is actuated by a stationary element to open or close the latch hook member when the piston cylinder device is respectively moving towards or from the retracted position.
