Abstract: "MODEM WITH IMPROVED DIGITAL SIGNAL PROCESSOR"   Abstract A modem with an improved digital signal processor is described. A first processor (12) controls the overall operation of the modem and communicates with an external device (not shown) through a connector (10). A second processor (34) performs signal processing on both transmitted and received data signals in a manner which saves both time and memory space. The processes which are described comprise a 2400 bit per second handshake signal detector, a fast linear-to-mu law converter, the transmitter signal generator, a fast-acting nonlinear automatic gain control, a jitter-free transmitter phase-locked loop, a baud clock timing recovery circuit, and a phase and amplitude modulator. Also described is a protocol for exchanging data between the processors (12) (34). A logic gate array (15) allows the processors (12) (34) to communicate with each other and also performs other functions. Therefore, each of the processors (12) (34) performs the operations for which it is most suited by its design.

Abstract: HAND TOOL FOR PRESSING WIRE CONNECTORS       Abstract of the Disclosure A hand tool for pressing wire connectors to establish electrical connection between a plurality of insulated wires inserted into the connector includes an elongated body having a mouth at one end for receiv-ing a wire connector with wires inserted therein.  A movable jaw is pivotally mounted on the body for move-ment about a first pivot laterally offset from a longi-tudinal axis of the body forming a movable wall of the mouth for compressing the connector to a precise geometric configuration.  An operating handle is pivot-ally connected to the jaw for movement about a second pivot on the jaw and the handle has an opposite outer end portion movable toward and away from the tool body for moving the jaw between open and closed posi-tions.  A thrust element is pivotally interconnected between a third pivot on the handle and a pivot point at the outer end of the tool body.  The handle is pivoted relative to the jaw on an operating stroke moving the jaw from an open position toward a closed position with a rapidly increasing mechanical advan-tage for providing a maximum compressive force gener-ally aligned with the longitudinal axis of the tool and transversely across the inserted connector as the third pivot approaches the longitudinal axis of the tool body.

Advantageously, a hydrogen halide is the source of hydrogen ions and halide ions.          The carbonylation is preferably integrated with a method of producing IBPE from isobutylbenzene wherein the latter compound is subjected to Friedel-Crafts reaction with an acetylating agent to produce 4-isobutylacetophenone, which is then reduced with hydrogen in the presence of a hydrogenation catalyst, or with a reducing agent containing available hydrogen, to obtain IBPE.  The palladium catalyst complex can be precipitated from an organic phase of the carbonylation reaction which typically includes the ibuprofen product.  The precipitated catalyst complex can be recycled without further treatment.
