Abstract: The present invention relates to cemented carbide bodies preferably for rock drilling and mineral cutting. Due to the fact that the bodies are built up of a core of eta-phase containing cemented carbide surrounded by a surface zone free of eta-phase with low Co-content in the surface zone and successively increasing Co-content to a maximum in the outer part of the eta-phase-core they have obtained an increase in toughness and life at practical use. <IMAGE>

Abstract: Objective: To make it impossible to change the settings on a dial-type timer except in a fixed range. Construction: Two setting rings are mounted on the perimeter of the dial in such a way that they rotate as a single entity with the said dial. Each of the rings has a single molded tooth on its outer edge. A stop protrudes from the body of the timer which is contacted by the aforementioned teeth on the setting rings mounted on the dial. When the teeth come in contact with the stop, the range of rotation of the said dial is constrained. Effects: Two setting rings are set in positions which indicate the upper and lower limits of a dial's rotation. When these rings are mounted on the perimeter of the said dial, the settings achieved by the dial can be changed only within the range between the said upper and lower limits. <IMAGE>

Abstract: An industrial process (2) is simulated, this process varying the value of each physical quantity Pi which is characteristic of its status, with a speed of variation Vi, on the basis of the status of control signals (3) sent out by an automatic control device (1), and which reports its status to the said automatic unit by means of status signals (4) sent by sensors as a function of the value of the physical quantity which they monitor. For each physical quantity Pi, the interval of time  DELTA ti is determined during which the value of the physical quantity may vary without any one of the sensors monitoring this quantity Pi changing state. Then the value of each physical quantity Pi is updated, by incrementing it by the value of the product of the speed of variation Vi with the time interval  DELTA t, which is the smallest of the previously determined time intervals. Finally, after having updated the sensors monitoring each physical quantity Pi, there is a time delay, the parameters of which can be set, before recommencing the procedure. The simulation procedure is used to test the logical and time-based operation of an automatic unit, such as an industrial programmable automatic unit. <IMAGE>

Abstract: The present invention provides a process for recovering arsenic acid from a starting mixture comprising sulfuric and arsenic acids and water. In step (a), the starting mixture is treated with a sulfur (IV) compound which will reduce the arsenic acid to arsenic (III) compound under conditions sufficient to substantially convert the arsenic acid to arsenic (III) wherein the resulting mixture comprises arsenic (III) compound, the sulfur (IV) compound, sulfuric acid, and water. In step (b), the resulting mixture is purged with inert gas to substantially remove the sulfur (IV) compound from the mixture wherein the purged mixture comprises the arsenic (III) compounds, sulfuric acid, and water. In step (c), the purged mixture is treated under conditions sufficient to substantially separate the arsenic (III) compounds from the purged mixture. In step (d), the separated arsenic (III) compound is reacted with an oxidizing agent to substantially convert arsenic (III) compound to arsenic acid wherein the final mixture comprises arsenic acid, unreacted oxidizing agent, and water. In step (e), impurities are removed from the final mixture to provide substantially pure aqueous arsenic acid. The recovered arsenic acid may be used for example as a raw material for the production of CCA wood preservative. The purged mixture which is sulfuric acid may be reused for example in the process of commonly assigned U.S. Patent 5,089,241. <IMAGE>

Abstract: Antibodies are retargeted to a target for which they have no functional specificity under normal circumstances. Use is made of a multi-specific binding substance which has binding specificity for the target and anti-antibody binding specificity. The binding substance may comprise an immunoglobulin antigen binding site and may be a "diabody". Depending on the antibody bound, effector functions such as Complement, ADCC and immune blocking are recruited to act on the target. Example targets are human cells. In vivo and in vitro utilities are exemplified, including lysis of tumor cells and agglutination of red blood cells.

The recesses and hole are inserted within the cavity of the socket with the tether free end inserted so as to lock the tether within the recesses and hole. The tether includes a plurality of projections, one projecting from the tether on each side of the locking member so that when the tether is locked to the locking member in the socket the tether cannot be removed. In a further embodiment, two locking members each having a pair of locking tangs are attached to a strap in tandem. The socket member includes a pair of uniquely identified socket cavities keyed so that only one cavity can receive the lead locking member. Unique indicia on the seal includes the identification of the keyed cavities to preclude tampering with a false reuse of the seal.

Date Jul. 18, 1996A method is described for forming a solution of cellulose in a tertiary amine oxide (such as N-methylmorpholine N-oxide) and a non-solvent for cellulose (such as water). The method involves the preparation of a mixture containing excess non-solvent, and removing the excess by heating the mixture to a temperature in excess of the boiling point of the non-solvent at a predetermined sub-atmospheric pressure, and feeding the heated mixture into the introduction zone of a mixing chamber at the predetermined sub-atmospheric pressure, so as to cause flash evaporation of some of the excess non-solvent. The mixture in the mixing chamber is then agitated by a rotor and transported through the mixing chamber whilst further evaporation of the non-solvent occurs. The cellulose solution thus formed is extracted from the mixing chamber, and the evaporated non-solvent withdrawn in cocurrent mode from the same end of the mixing chamber. Apparatus for carrying out the method is also described.

Abstract: In an external storage, an I/O process is continued without any intervention of a user or a host system at failure of a controller. When a failure occurs in a controller (30), a host system 10 recognizes the failure of the controller (30). Before the failure is notified to the user and application to stop the job, the substitutive controller (40) reads the SCSI-ID possessed by an SCSI port (31) of the failed controller (30) from a shared memory (50), registers the SCSI-ID of the SCSI port (31) to the SCSI port (41) associated with the substitutive controller (40), and erases by a port address resetting facility 45 of the substitutive controller (40) the SCSI-ID possessed by an SCSI port (31) of the failed controller (30). Thanks to the provision, since the SCSI-ID specified at issuance of an I/O request is transferred between the controllers, the user or the host system need not alter the I/O request issuing route. Moreover, while the host system (10, 20) does not recognize the error, the transfer can be conducted. <IMAGE>

Abstract: In an optical coupling device for a node in a self-healing optical network, the number of switching elements is reduced by using a novel type of optical 2 x 2-switch (20). The switch has two switching states, viz. a bar state (ss1), in which a first and a second main port (25, 26) are optically coupled through to, respectively, a first and second secondary port (27, 28), and a half-cross state (ss2), in which the main ports are coupled through to one another, and the secondary ports are not involved in any through-coupling. An integrated design of the switch is based on two asymmetric Y-junctions coupled to one another via a common side branch in which electrode means are active in order to vary the propagation constant. The use thereof leads to a compact, integrated version of the optical coupling device with only two switching elements. <IMAGE>
