Abstract: The abovementioned compounds are prepared by reacting trialkyl phosphites with phosphorus trichloride and/or monoalkyl esters of dichlorophosphinous acid at -20 to +100 DEG C followed by immediately reacting the product with alkylmagnesium chloride or alkylmagnesium bromide at -60 to +50 DEG C, followed by removing the desired compounds from the distillate of the volatile compound. This allows dialkyl esters of alkylphosphonous acids and monoalkyl esters of dialkylphosphinous acids to be obtained without complicated and costly purification of intermediates. The phosphorus-containing esters obtained, in turn, are valuable intermediates, for example for the preparation of flameproofing agents and crop protection agents.

Abstract: In a rack for the detachable coupling of profiled beams, a connector is arranged in the cavity of the one profile beam, said connector being equipped with a retaining element. The retaining element is provided with a hook, which projects out of the profile, can be inserted into a groove in the other profiled beam and engages behind the latter when coupled. The retaining element is held via an eccentric bolt such that it can be displaced longitudinally in a bearing housing belonging to the connector, for which an eccentric disc is responsible which is arranged between a front and a rear control projection of the retaining element. In order to be able to withstand high clamping forces it is proposed that the inner end of the retaining element be bent back to form a double-layer fold, which forms the rear control projection for the eccentric disc.

Abstract: A method and apparatus for preprocessing and demodulating M-ary PSK signals wherein the modulation is limited to phase transitions between adjacent phase transitions between adjacent phase states. The method of preprocessing comprises generating (112) harmonics of the modulated source signal prior to demodulation thereby to expand the phase differential between adjacent phase states, and then demodulating (116) one of selected harmonic signals as if it were a simple two or four phase PSK signal. The method of demodulating may be operative in a demodulator which comprises a phase splitter dividing a source signal into two or three paths with a preselected phase relationship among phases, one of the phases being delayed by nominally one bit period, one or two mixers or multipliers, each one of the mixers receiving as one input a representation of the delayed-phase component and as a second input a representation of one of the remaining phase components. The signals provided by the mixers are then combined in a predetermined manner, if necessary, then compared by at least one two-level comparator to provide a digital output. Digital logic circuitry responds to the digital outputs of each of the comparators to map the digital outputs into a single digital bit stream of ones and zeroes.

Abstract: A multiple ramp analogue-to-digital converter comprises an integrator connected to receive and integrate an analogue input signal to be converted, and an opposing coarse reference signal. Instead of these signals being applied to the integrator sequentially, as is conventional, they are applied simultaneously. A flash converter is used to provide a rough initial estimate of the magnitude and polarity of the analogue input signal, so that the duration of application of the course reference signal can be estimated in advance. A fine reference signal is then applied to the integrator to restore its output to zero and improve the resolution of the conversion.

Abstract: Coextrusion apparatus for varying the outer profile of a generally tubular extrudate (19) formed by inner and outer streams of elastomeric material by varying the annular end opening of an elastic die ring (45) which varies the size of an outer extrusion orifice and consequently the flow of the outer stream of elastomeric material which is deposited on the outer surface of the tubular extrudate. A hydraulically moveable piston (57) is axially slideably mounted for engagement with the elastic die ring and has a wedge-shaped camming surface which moves along the outer surface of the elastic die ring to vary the size of the outer extrusion orifice and consequently the amount of elastomeric material extrudated therethrough. A linear motion detector (65-69) is connected to the piston to detect the amount of linear axial movement of the piston to provide control signals for controlling the movement of the piston. The orifice for the inner stream of elastomeric material is located slightly upstream of the orifice for the outer stream of elastomeric material and is generally fixed. A reinforcing guide (14) directs a plurality of fiber-type reinforcing elements (15) into the tubular extrudate generally at the merger of the inner and outer streams of elastomeric material.

Abstract: An improved rotating drag bit for cutting plastic, sticky, water reactive and shale formations is devised by providing a plurality of large diamond cutters having a circular cutting face in excess of a three quarter inch in diameter. Each large cutter is provided with at least one hydraulic nozzle which in turn provides a directed hydraulic flow at the corresponding cutter face. The directed hydraulic flow is positioned to apply a force to the chip which tends to peel the chip away frog the cutter face. In addition, the hydraulic flow is positioned with respect to the chip so as to apply an off-center torque to the chip which is used to peel the chip away from the cutter face and toward the gage of the bit. In particular, the nozzle defines a jet which is characterized by a direction and velocity of hydraulic fluid determined by the jet characteristics. The core is generally symmetric about its longitudinal axis and has a length along the longitudinal axis and width perpendicular thereto. The point of the jet most distant from the nozzle defines an impact point of the jet against the chip and cutter face. The longitudinal axis of the jet is chosen so that at least a portion of the jet axis lies between the cutter face and the chip as it is being peeled from the cutter. Hydraulic removal of the chips is further facilitated by a plurality of junk slots having a contained compound surface. The jug slot is characterized by having at least two distinct cross-sectional profiles, namely an asymmetric profile at its lower portion nearest the bit face and a symmetric profile along its upper portion. The asymmetric and symmetric profiles are connected by a surface providing a smooth hydrodynamic transition.
