IPC: E21D9/06
Filed: 1990-10-31
Abstract: In a driving shield (1) with an essentially cylindrical supporting frame (2) on which a sliding casing (4) for producing a lining (11) consisting of a hardening material, in particular concrete, is mounted in an axially displaceable manner and with an end casing (12) closing off the front end of the sliding casing (4) in a sealing manner, shield-driving presses (6) for pressing the shield (1) forward are supported on the sliding casing (4), the sliding casing preferably consisting of a plurality of elements displaceable relative to one another in the axial direction of the shield (1). In this arrangement, the static friction (F 1) between the outer surface (10) of the sliding casing (4) and the lining (11), which static friction (F1) exceeds the sliding friction (F2) between the sliding casing (4) and the supporting frame (2), is used for pressing the shield forward for applying the thrust forces. <IMAGE>

Filed: 1990-02-22
Abstract: A matrix for implantation in a mammalian host comprising biocompatible, mineral-free, insoluble Type-I bone collagen which may be allogenic or xenogenic to the host, and which, when implanted in the host, is biodegradable. The collagen is treated with a collagen fibril modifying substance such as acidified acetonitrile, chloroform, or dichloromethane, or by heating in an aqueous environment to a temperature of 37 DEG -65 DEG  C. The treated material undergoes a change in morphology involving a significant increase in its surface area as measured by various methods. Under the scanning electron microscope the material has an "oyster shell" appearance with many pits and micropores.

Title: Apparatus for assessing a particular property in a medium.
Inventor: CULSHAW BRIAN CROMDALE GRYFFE
IPC: G02B26/00
Filed: 1990-10-19
Abstract: For assessing a particular property of a medium (13) a sensor (18) is provided which is sensitive to the property and which is thermally activated when in contact with the property containing medium. The sensor (18) is externally mounted on the undersurface of a silicon wafer (9) the uppersurface of which contains a well in which a vibratile bridge element (16) is located. The top of the well is closed off so that the element (16) is within a closed chamber (15). Excitation energy (12) from a source (14) is delivered to the element (16) to establish vibratory motion which is monitored and detected by a circuit (19). Presence of the property in the medium (13) causes a thermal change in the wafer (9) resulting in a change in the resonance frequency of the vibratory motion of element (16). The frequency shift is a measure of the property.

Abstract: The invention relates to a method and a device for forming machine currents (iw, ip, im) in a converter-fed rotating field machine (10) as a function of a measured intermediate-circuit current (id). According to the invention, the measured intermediate-circuit current (id) is integrated over times during which either any desired or a specific active voltager vector (u1,...u6) is set by means of a combination of switched-on converter valves (T1,...,T6) of the pulse-controlled invertor (8). In this way, the active current (iw) and two currents (ip, im) of the rotating field machine (10) can be simulated, the positive current (ip) being formed from positive phase currents (iR, iY, iB) and the negative current (im) from negative phase currents (-iB, -iR, -iY), and it being possible to form these currents from the knowledge of the angle ( gamma ) of the rotating voltage space vector (u*) into continuous phase currents (iR, iY, iB). <IMAGE>

Title: Method for sizing of paper
Inventor: SAWAYAMA SHIGERU
IPC: D21H21/16
Filed: 1991-04-19
Abstract: The present invention relates to a method for sizing of paper by using a particular vinylamine polymer as a size-fixing aid. By the use of the vinylamine polymer as a size-fixing aid, it has become possible to obtain a paper having superior sizing properties by papermaking at a pH around neutrality using a hitherto known acidic sizing agents without using a neutral sizing agent. The method of the present invention further has effects that operating efficiency of papermaking is greatly improved since contaminations of a papermaking machine due to a neutral sizing agent can be avoided, and therefore, the prices of paper can be greatly lowered. The present method has further advantages when it is applied under acidic papermaking condition of a pH of less than 5.5. In such a condition, the addition amount of alum can be decreased and the life of a papermaking machine can be prolonged. In spite of a small amount of alum added, a considerably good sizing effect can be obtained by the present method.

Abstract: An electro-strictive actuator of the present invention comprises an electro-strictive element (2) having a first surface through which a mechanical displacement is output; and a mechanical member (10) having a second surface which directly contacts the first flat surface so that the mechanical displacement of the electro-strictive element is output without attenuation to the technical member, where the first or the second surface is provided with a ditch (12) filled with a first adhesive (13.1) for adhering the electro-strictive element (2) to the mechanical member (10). A portion of the side of the electro-strictive element in the vicinity of the second surface may be additionally adhered to the second surface by a second adhesive (13.2). Deletion of adhesive in the contact between the first and second flat surfaces allows a good propagation of the mechanical displacement output from the electro-strictive element to the mechanical member, while an adequate adhesion strength is achieved by the adhesive in the ditch.

Le séquencement concomitant des lignes du premier réseau et du second réseau est répété sur une pluralité de cycles, de manière à faire croître, par cumul des secondes sous-charges successives dans la ligne bouclée, la charge correspondante du réseau mémoire. On accroît ainsi, par la seconde intégration résultante, la dynamique du dispositif à transfert de charges dans une proportion correspondant audit rapport prédéterminé des deux sous-charges, typiquement de 40 dB (portant ainsi la dynamique, par exemple, de 120 à 160 dB) pour un rapport de 100:1. <IMAGE>
