Abstract: ABSTRACT OF THE DISCLOSURE    Novel derivatives, e.g. salts of a compound of the Formula I                              I in which X stands for a halo, e.g. chlorine, bromine, or iodine, and prefer-ably is a bromine, with a .beta. -lactam antibiotic or a pro-drug thereof con-taining a basic group are provided herein.  They are prepared by reacting a solution of potassium 6 .beta. -halopenicillanate, where halo is chloro, bromo, or iodo, with a solution of the antibiotic or a pro-drug thereof, or by treating an organic solvent solution of a 6 .beta. -halopenicillanic acid, wherein halo is chloro, bromo, or iodo, with an organic solvent solution of the antibiotic. Examples of such .beta. -lactam antibiotics include penicillins, cephalosporins, substituted 6 .beta. -amidinopenicillanic acids, ampicillin, amoxycillin, cepha-lexin, cefaclor, and mecillinam, and pro-drugs thereof e.g., pivmecillinam, bacmecillinam, penethamate, pivampicillin, and bacampicillin.  Processes for the preparation of such derivatives are also provided which involve interrac-tion of solutions, e.g. organic solvent solutions, of the reactants.  The .beta. -halopenicillanic acids of formula I are potent inhibitors of .beta. -lactamases from a variety of gram-positive and gram-negative bacteria, making the above-described derivatives of .beta. -halopenicillanic acids valuable in human and veterinary medicine.

Abstract: ABSTRACT OF THE DISCLOSURE           A spring-powered actuator especially for operating devices such as fire and/or smoke dampers, doors, hatches, vents, traps, valves and other devices having components which are movable between at least two positions.  The spring-powered actuator of the invention comprises a longi-tudinally-displaceable re-wind screw which is rotatable to recharge the spring of the actuator, and a tilting element on the screw which is mounted for tilting movement with respect to the screw axis to allow longitudinal movement of the re-wind screw so as to permit rapid and reliable re-lease of energy stored in the spring.  When used in a com-bination fire and smoke damper, it thus opens or closes the blades of the latter.

Abstract: ABSTRACT            The printer comprises a solid or liquid ink jet head arranged to print one dot at a time on paper running over a platen.  The head is carried by a carriage movable transversely with simple harmonic reciprocating motion. In order to reduce the effect of inertial forces when the carriage reverses its movement, the drive is effected by an eccentric peg on a disc, the peg engaging in a guide slot of the carriage perpendicular to the direction of reciprocation.  An eccentric cam track in the disc engages a peg on a counterweight for counterbalancing the inertial forces of the carriage.  In order to synchronize the print-ing operation with the carriage movement, an optical strobe disc is rigid with the disc and has slots disposed at a pitch varying according to the harmonic motion.  The platen is rotated intermittently by a helical cam carried by the disc and a peg wheel.  In order to compensate for discharge of a smoothing or reservoir circuit feeding the printing head, the duration of the pulses applied thereto can be increased in accordance with the rat  at which dots are being printed.  In a modification the strobe disc is re-placed by a linear transducer of capacitive type, with one part carried by the carriage.

Abstract: ABSTRACT OF THE DISCLOSURE      A cladding process is disclosed wherein hard carbide cutter inserts, as well as polycrystalline diamond composites, are metallurgically bonded in-into an interior core of a drag bit body.  The cladding is bonded onto the exterior surface of the core of the drag bit by a powder metallurgy process.  A thin layer or coat-ing of a suitable metal, preferably nickel, is pro-vided on, for example, the carbide inserts prior to mounting into the core.  The coating prevents degra-dation of the carbide through loss of carbon into the core during the powder metallurgy process and accommodates mismatch of thermal expansion between the cutter insert and the core.
