Abstract: In order to control the auto-sampler in a device such as a gas chromatograph in which data is sampled by an analog-to-digital converter, the converter providing outputs indicative of its status and having one state when the converter is enabled, another state when the converter is disabled and pulsing between said states when the converter is acquiring data, an automatic injection control device is provided which: counts the sampling pulses from the converter to insure that a full conversion cycle has been completed and sets a first signal to so indicate; through a retriggerable, one-shot multivibrator insures that the last of the sampling pulses is completed and provides a second signal accordingly; and adds these two signals with the status signal indicating that the converter is in a condition to receive data to provide a trigger signal for use by the auto-sampler.Further, a method for generating triggering signals to initiate such event is presented.

Abstract: There is provided a method for enhancing the growth rate of meat-producing animals and/or improving the efficiency of feed utilization thereby, which involves, orally or parenterally, administering to said animals a growth-enhancing amount of a phenylethane compound or the acid addition salt thereof.

Abstract: The physical properties of structural surgical elements which are made from bioabsorbable materials having a glycolic ester linkage can be controlled so that the rate of strength loss and degradation in vivo is altered to achieve disintegration into fragments suitable for removal from or passage through the body without the need for waiting until the material is absorbed. This is achieved by a method of modifying the element through various chemical and/or physical treatments, preferably irradiation, or combinations thereof, with the result that bioabsorbable structural surgical elements are made more controllable in their strength loss and degradation pattern.

Abstract: Poly(glycolic acid)/poly(oxyalkylene) ABA triblock copolymers having the following formula: ##STR1## and wherein x and y have values which correspond to a total polyglycolide content of about 75 to 95 weight percent and a total polyoxyalkylene content of about 5 to 25 weight percent. The copolymers are useful for manufacturing fibers possessing a sufficiently low modulus of elasticity to permit their use as absorbable sutures having the requisite flexibility for use in monofilament form. A process of preparation involves purifying the hydroxyl-ended poly(oxyalkylene) and allowing it to react with glycolide to produce an ABA triblock copolymer of extrusion grade in which A represents a polyglycolic acid block and B represents a poly(oxyalkylene) block.

Abstract: A triblock copolymer having a proportion of units having the formula: ##STR1## as the end blocks, and the formula (I) randomly combined with a proportion of units having the formula: ##STR2## as the middle block finds particular advantageous use in manufacturing absorbable monofilament sutures and other surgical articles. A surgical article is manufactured from a synthetic absorbable copolymer formed by copolymerizing glycolide with 1,3-dioxan-2-one (trimethylene carbonate) wherein a combination of the monomers is substantially completely polymerized before the addition of the other monomer in the presence of a difunctional initiator at or below about 180.degree. C.; glycolide is added and the temperature increased up to about the melting point of poly glycolide to form a triblock copolymer with a proportion of units having the formula: ##STR3## as the end blocks, and the formula (I) randomly combined with a proportion of units having the formula: ##STR4## as the middle block.
