Abstract: This invention relates to tooth treatment compositions and has particular application to desensitising compositions for use on so-called hypersensitive teeth. Tooth sensitivity is exhibited when a sufferer experiences a painful reaction to inter alia pressure, hot, cold, sweet and the like stimulus of a tooth surface and tooth desensitatising compositions for the treatment of tooth hypersensitivity are well known for home use in oral hygene regimens. Such compositions may supplement or replace therapy undertaken by a dentist. 
     The present invention provides a tooth treatment composition in liquid or paste form including an antihypersensitivity-effective amount of potassium and citrate ions.

Abstract: A reverberator comprises a tapped delay line (2, 3, 4, 5, 10) connected to an analog audio signal source (1) for deriving therefrom at least one pair of output signals which are respectively delayed by first and second different values with respect to the source signal, the ratio of the first to second values being an irrational number. A recirculating delay line (6, 7, 11, 12) is connected to the output of the tapped delay line having a delay element (63, 73, 113, 123) for introducing an additional delay to the output signals of the tapped delay line and a resistive recirculating path (65, 75,115,125) for recirculating the additionally delayed signals through the delay element. The output of the recirculating delay line is combined with the source signal to derive a reverberating audio signal.

Abstract: A run-out skeleton step 3 for motor vehicles or the like is constructed in such a way that it can be quickly and briskly moved by a power drive device without severe loading jolts occurring when the respective end position is reached. It is arranged at the front end of two profile rails 15 and 16 with, for example, U- or C-shaped cross-section and is supported and guided by means of the latter on fixedly mounted running rollers 12 so that it can be moved transversely to its longitudinal axis. A fixedly anchored power drive device 23 acts with linear movement on the skeleton step 3. A tension spring 20, 21 engages on each profile rail 15, 16 with a direction of action extending essentially transversely to the direction of movement of the skeleton step 3. The fixed bearing surfaces 8 for the tension springs 20 and 21 have, relative to the movement path of the skeleton step 3, an arrangement in which the tension springs 20 and 21 assume, in each of the two end positions of the skeleton step 3, a position which is inclined at an acute angle with respect to their direction of movement. The power drive device 23 consists of a torque spindle drive with an electrical geared motor surrounding the latter and it is active on the plane which is central or symmetrical to the two profile rails 15, 16 whilst the fixedly anchored ends of the tension springs 20 and 21 of the central or symmetrical plane are closer than their end engaging on the profile rails 15 and 16. <IMAGE>

Abstract: @ A method for controlling both shared and exclusive access for a resource in a multiprocessor system wherein a first-in/first-out queue is formed for tasks suspended while awaiting access and wherein access to the resource provides that control of access required for manipulation of the first-in/first-out queue which is not provided by the atomic nature of compare (double) and swap. Each member of the queue has indicators of the access which it requested and of the next most recently enqueued member which has a corresponding indicator. A lockword is established having two parts, a lock flag indicating the status of the resource, whether available, under shared ownership or under exclusive ownership and a lock pointer pointing to the most recently enqueued task. In requesting or releasing access, an initial guess is made as to the value of the lockword and a projected lockword is calculated based on the guess. Then an atomic reference is made to the lockword during which no other multiprocessor has access to the lockword. During the atomic reference, the lockword is compared to the guess of the lockword and if the guess is correct, the lockword is replaced by the projected lockword which rearranges the queue for the requesting or releasing task. If the guess was incorrect, the value of the lockword is used to calculate another projected lockword. If another task can effect the next tasks to gain access, the process with the atomic reference is repeated until no intervening changes occur between atomic references.

Abstract: 57 A semiconductor memory device in which the differential amplifier circuit compares a potential of a bit line to which memory cells storing information are connected with a reference potential of a dummy line to which a dummy cell is connected, and detects information stored in each of the memory cells. The semiconductor memory device comprises a circuit which discharges both the bit line and the dummy line to a low potential when the chip enable inverted signal is supplied. When the chip enable signal is supplied, therefore, the differential amplifier circuit can detect a difference between the bit line potential and the dummy line potential before the bit line is fully charged up. This makes it possible to produce the chip enable access time and to realize higher speed operations.

Im weiteren sind zwei über innere Transportbandwalzen (21, 22) geführte teigtransportbänder (10, 11) vorgesehen. Zwischen den Transportbandwalzen (21, 22) und der unteren Auswalzwalze (15) befindet sich je eine Messwalze (23, 24). Der Teig wird in mehreren Durchgängen ausgewalzt, wobei abwechslungsweise ein Transportband (10 resp. 11) als Zuführband dient. Die Drehgeschwindigkeit der Auswalzwalzen (14, 15) sowie des den Teig wegtransportierenden Transportbandes sind konstant. Die Geschwindigkeit des den Teig zuführenden Transportbandes ist regulierbar und wird durch die, die effektive Zuführgeschwindigkeit des Teiges messende Messwalze (23 resp. 24) reguliert. Die optimale Steuerung der Geschwindigkeit des zugeführten Teiges ist sehr wichtig, um ein Wellenschlagen oder ein zu starkes Strecken des Teiges zu vermeiden. Die obgenannten Fehler können den Teig zerstören oder bedingen eine erneute Vornahme des Auswalzvorganges oder einen zu grossen Ausschuss bei der Weiterverarbeitung des Teiges. Die Teigauswalzmaschine kann ohn Operateur betrieben werden.

Abstract: The invention comprises a method of mounting a cutter, having a stud portion 24 defining one end thereof and a cutting formation 14 generally adjacent the other end in a pocket22 in a drill bit body member 12. The method includes the steps of forming a channel such as a tube 10, extending into the pocket, inserting brazing material into the channel, inserting the stud portion 24 of the cutter assembly into the pocket, then heating the bit body member to cause the brazing material to flow through the channel into the pocket, and finally recooling the bit body member. During the assembly of the various pieces required in the steps mentioned immediately above, a spring 48 is used, co-operative between the cutter and the bit body member, to retain the stud portion in the pocket and also to displace the stud portion toward the trailing side of the pocket.
