Abstract: A method and apparatus for preparing end faces of integrated circuit chips using a cutting machine having a straight blade. The apparatus is a wedge shaped block having one surface angled at the desired angle to be imparted to the end face. The one surface has an alignment member thereon for aligning the chip on the top surface, and at least one locating member at the end of the block for positioning the end of the chip relative to the cutting blade. The block has a plurality of bores therein for applying suction to hold the chip on the one surface during cutting with the blade. The method includes the steps of placing a foot or feet on the chip, placing the chip on the block and aligning it and locating it, and applying a force thereto to hold it fixedly in position.

Abstract: A method for preparing operative end faces of integrated circuit chips or dies utilizes a beveled cutting blade to impart a desired contact angle to the operative end faces of the chip. The method includes the steps of mounting feet on the chip, trimming the feet where necessary, mounting the chip on a fixture with tape, cutting the end faces, and removing the chip from the fixture.

Abstract: A compound of formula (I) or a salt thereof: ##STR1## wherein: P.sup.1 is pyridyl;P.sup.2 is phenyl;A is a bond or a chain of 1 to 5 atoms optionally substituted by C.sub.1-6 alkyl;R.sup.1 and R.sup.2 groups are each independently hydrogen, C.sub.1-6 alkyl optionally substituted by NR.sup.12 R.sup.13, C.sub.2-6 alkenyl, C.sub.2-6 alkynyl, cyano, halogen, CF.sub.3, NR.sup.12 R.sup.13, CHO, OCF.sub.3, COR.sup.14, CH.sub.2 OR.sup.14 or OR.sup.14 where R.sup.12, R.sup.13 and R.sup.14 are independently hydrogen or C.sub.1-6 alkyl;n and m are independently 0, 1 or 2;R.sup.3 is hydrogen or C.sub.1-6 alkyl;R.sup.4 is a group of formula (i): ##STR2## in which: R.sup.6 and R.sup.7 are independently hydrogen, C.sub.1-6 alkyl optionally substituted by one or more fluorine atoms, C.sub.1-6 alkylthio, C.sub.1-6 alkoxy or halogen.

Abstract: The invention relates to heterocyclic families of compounds having pharmacological activity, in particular possessing 5HT.sub.2C receptor antagonist activity processes for their preparation, to compositions containing them and to their use in the treatment of CNS disorders.

Abstract: Novel heterocyclic compounds having pharmacological activity, processes for their preparation, to compositions containing them and to their use in the treatment of CNS disorders are disclosed.

Abstract: The invention relates to a method for preparing a biodegradable aliphatic polyester, which comprises polymerization of a precursor of the polyester in the presence of a polyesterification catalyst in an amount of up to 0.1% by weight, based on the weight of the cyclic precursor, and a co-catalyst comprising glycerol or butyrolactone in a weight proportion of not more than three times that of the catalyst.The invention also relates to the use of the resulting biodegradable aliphatic polyester in polymer processing, such as injection molding or compression/press molding.

Abstract: An automatically controlled liquid dispensing system including a reagent dispenser adapted to function as an intermediate container for dispensing relatively small controlled volumes of liquid to an associated receiving system in a continuous "demand" mode, this dispenser being indirectly monitored to be automatically and continually replenished after liquid is withdrawn therefrom, using a simple photoelectric liquid level monitor system including a fail-safe overflow control arrangement.

Abstract: An arrangement for the controlled delivery of liquid reagent is shown wherein a reservoir vessel for storing the liquid in volume is coupled to replenish a "vestibule vessel" provided for intermediate storage of the liquid enroute to the delivery point and for pneumatic propulsion thereof, the liquid being pneumatically driven from reservoir to the vestibule through a unidirectional check valve.

Abstract: An apparatus for setting fiber crimp by steam in which a crimped filamentary tow is discharged from the tow exit portion of a stuffer-box crimper into an elongated tube sealed to said exit portion and control means for simultaneously regulating steam pressure and the discharge of tow from the tube depending upon the pressure of steam therein.
