Patent EP-0393415-A1 (EP)
Inventor: CATANESE JOHN ANTHONY
IPC: C25F7/00
Filed: 1990-04-03
Abstract: An electrolytic etching apparatus for marking metal tubes (T), including two electrodes (18,20) defining an etching station therebetween; a wicking pad (28) which has a wetting portion (28A) disposed on the face of one electrode (20) and extends into an electrolyte reservoir (26) disposed at a level below the etching station; and a continuous stencil (24) wound on spools (14,16) and draped over the wetting portion (28A) of the wicking-pad, the stencil being imprinted with identification indicia adapted to be sequentially moved into position at the etching station through rotation of the spools. An electrolytic etching action for marking a metal tube (T) placed between the imprinted stencil portion at the etching station and the other electrode (18) is effected by moving the latter against the metal tube (T) to apply pressure, and then applying a suitable voltage to the electrodes (18,20).

IPC: C12R1/19

Abstract: The present invention relates to processes for purifying annexines. The overall process includes the steps of preparing a homogenized cell preparation and adjusting the pH to about 8.0 to 10.0, adding at least one bivalent cation, adding a phospholipid, washing the insoluble cell residue to remove the soluble constituents, and extracting the annexines from the cell residue with a chelating agent. This process initially promotes the adsorption of the annexines onto the insoluble cell residue or membrane of the host organism. The adsorption step makes it possible to eliminate unwanted soluble matter from the homogenized material by simple washing. Desorption is accomplished by using a chelating agent.

Title: Feed screw device
Inventor: YAMAMOTO NOBUHIRO
IPC: F16H25/24
Filed: 1990-11-06
Abstract: In a feed screw device (1) according to the present invention, a coil member (3) is disposed on the outer periphery of a rotary shaft member (2). The coil member (3) is formed of an elastic body such as a priece of piano wire. The coil member (3) is mounted at least partially on the shaft member (2) so as to have at least a portion remaining in a free state. The coil member (3) is used to engage a nut placed on the outer periphery of the shaft member. When the shaft member is rotated, the coil member (3) is also rotated together with the shaft member (2), so that the nut is moved in the axial direction of the feed screw (1). When the nut is brought into contact with a stopper by a driving force, the nut impactively strikes the stopper. However, since the coil member (3) can be elastically deformed in the axial direction, the coil member (3) is elastically deformed to absorb its impact. Also, the "spring back" effect enabled by the deformable coil member (3) serves as a contribution to the initiation of movement of the nut in the reverse direction. Thus, when the direction of the driving force is reversed, the nut can immediately be moved in the reserve direction by a slight driving force.

Abstract: For the autogenous cutting of metal workpieces (Fig. 1, (2)) with an autogenous cutter (4), residues are generated by the cutting jet (6) of the autogenous cutter, which are removed underneath a working grate (3), on which the workpieces to be cut rest. In order to draw off the residues directly at their point of generation, it is envisaged to draw off the gaseous and dusty residues via draw-off ducts (7), which run parallel to the plane of the working grate (3), in the region of the cutting jet (6) penetrating the workpiece. The drawing off takes place in the opposite direction to the direction (13) of the cutting jet. <IMAGE>

Abstract: An optical transmission system includes a power splitter (10) for dividing an RF input signal (9) into a plurality of intermediate signals (11, 12) each assigned to a respective one of a plurality of parallel optic links Each link optically transmits its respective intermediate RF signal over a respective fiber line (14) before being detected at a receiver end. The detected signals are combined by an RF power combiner (17) into an output signal (18) having an enhanced signal to noise ratio that is better by 10 log n dB over that of a single link, where n is the number of parallel links. In order to permit operation at arbitrarily high frequencies, a pilot tone delay equalization circuit (16) is coupled to each link at the receiver end for equalizing the delay variations between the various fiber paths.

Abstract: Circuit pour tester le bon fonctionnement d'un détecteur de gaz électrochimique ampérométrique (10), lequel contrôle la concentration de gaz toxiques dans une atmosphère. Le détecteur (10) est muni d'électrodes de détection (12), d'un électrode de référence (14) et d'une contre-électrode (16). En fonctionnement normal, la tension entre les électrodes de détection et de référence est fixée moyen d'un amplificateur asservi (18); lorsque l'atmosphère contient du gaz, celui-ci réagit électrochimiquement à l'électrode de détection (12) et modifie en conséquence la tension entre les électrodes de détection et de référence. Cette modification amène l'amplificateur (18) à alimenter en courant électrique la contre-électrode. Un courant électrique proportionnel à la quantité de gaz toxique contenue dans l'atmosphère passe alors par le détecteur. Le bon fonctionnement de ce dernier est régulièrement testé. Pour ce faire, on applique un potentiel impulsé entre les électrodes de détection et de référence; si le détecteur marche correctement, un courant passe alors par le détecteur (10) et par le circuit et est détecté par un système d'alarme (33) connecté à un potentiomètre (30) par un interrupteur (30a) pendant les périodes d'essai. Si le système d'alarme (33) ne détecte pas de courant, ceci signifie que le détecteur ne fonctionne pas correctement et le système donne l'alarme (33).

Abstract: The test device represents a combination for testing the insulating performance of three-phase switching systems and for testing the electrical strength of the insulating gas in switching systems which are in use. A duct (2), which is permanently installed in the encapsulation (9) of a gas-insulated switching system, is penetrated by a test conductor (1), which can move longitudinally and in the rotation direction, on whose inside there is arranged a test electrode 4 which can pivot and has a preferably spherical contact (6). By rotating the test conductor (1), the contact is alternately brought into connection with the conductor pieces (5) of a three-phase switching system. In a further test position, the contact (6) is at a distance (A) from an earthed electrode (7) at which the breakdown strength of the insulating gas can be tested using a suitable test voltage. In a fifth position, the contact (6) touches the earth potential and thus prevents the test electrode remaining charged after a test has been carried out and generating a dangerous contact voltage on the outside of the switching system. The invention contains the further safety measures which ensure in a simple manner that the test electrode (4) is always at earth potential when the switching system is in the normal operating mode. <IMAGE>

Abstract: An improved radar receiver transmitter uses a single frequency shift keyed oscillator (10) which shifts rapidly between a pulsed output frequency and a local frequency such that the system can transmit at one frequency and shift fast enough such that when the echo pulse is received, the oscillator is operating at the local frequency desired. The two signals are demodulated in a mixer (24) to establish the desired intermediate frequency which then may be processed to produce the desired output. Extremely fast shifting is accomplished by a gallium arsenide oscillator (11) in conjunction with a varactor diode (12) which responds to a modulator pulse.

Abstract: In the manufacture of mozzarella cheese, aging can be dispensed with if the process is controlled to yield a combined moisture and wet milkfat content of at least about 70 weight percent, and the cheese will provide acceptable bake performance under typical cooking conditions used in the pizza industry today. Within about 48 hours after brining, the cheese should either be used or frozen. This discovery saves at least seven days of aging and permits the use of a continuous process of making mozzarella, which, from pasteurization to loading of the frozen product on the truck, can be performed in as little time as eight hours. In the continuous process, the hot stretched cheese from the kneading machine is extruded directly into cold brine. After the cheese has cooled sufficiently, it can be comminuted and frozen by independent quick freezing, preferably in a fluidized bed freezer. Salt preferably is mixed into the cheese during the kneading step.
