Title: Recovering triarylphosphine from poisoned rhodium catalyst systems
IPC: C07F9/50
Filed: 1982-04-19
Abstract: A process for recovering reusable triarylphosphine (e.g. triphenylphosphine) from rhodium catalyst residues poisoned by the presence of alkyldiarylphosphine (e.g. n-propyldiphenylphosphine) such as are obtained as spent catalyst residues from the hydroformylation of olefins comprises subjecting the poisoned residues to evaporative separation under reduced pressure to separate a vapour comprising triarylphosphine from the rhodium, condensing the vapour and subjecting the condensed vapour to a milder evaporation process to form a concentrate and then mixing the concentrate with polar solvent and obtaining the triarylphosphine as a crystalline precipitate from the solvent. The crystalline phosphine is sufficiently free of poisons to be re-usable as a catalyst component in a hydroformylation process.

Title: Circuit arrangement for a disk player for reproducing information prerecorded in the form of pits
IPC: G11B7/005
Filed: 1982-05-06
Abstract: In a circuit arrangement for a disk player of the type arranged to reproduce information prerecorded in the form of pits, a rectangular wave signal is produced by processing the sinusoidal-like wave signal produced by a pickup 2 scanning the pits on spiral or coaxial tracks on a prerecorded disk 12. The average D.C. voltage of the rectangular wave is produced by a circuit 11 and fed back to an input of the circuit 10 which produces the rectangular wave signal so as to automatically change the threshold thereof. Since the threshold is changed in accordance with the output rectangular wave signal, data errors due to distorted sinusoidal signal caused by dull or blunt edged pits are effectively prevented, providing uniform and accurate reproduction of data throughout the entire disk. <IMAGE>

Title: Shelving arrangement
Inventor: HAYCOCK IVAN JAMES
IPC: A47B57/34
Filed: 1983-03-03
Abstract: A shelf (13) is supported between upright standards spaced apart by a distance equal to the length of the shelf, the mutually facing surfaces of the standards bearing opposed vertically spaced horizontal grooves. The brackets are secured to the shelf ends and are of resilient wire construction such that, when relaxed, they are canted outwardly (dashed lines, Figure 1). To fit a shelf between the standards the brackets are sprung towards each other and the rearward ends of wires 10 are entered into respective grooves in the standards. The brackets are then relaxed to allow the horizontal parts of the rearwardly extending hooks 14 to enter further higher grooves on the standards, the downwardly depending parts of the hooks 14 thereby being engaged with a rearwardly directed face of the standard to prevent 'pulling-out'. In an alternative bracket (Figure 5) wires 10 and 27 are replaced by a plate from which wires 28, 29 extend, the rear edge of the plate serving the same function as the projecting end of wire 10. In a further alternative bracket for slatted shelves (Figure 6) the bracket is adapted to engage dowels which interconnect the slats. <IMAGE>

Title: Timing apparatus for rotating parts
Inventor: LEARY JEROME JOSEPH JOHN
IPC: F02P7/077
Filed: 1983-07-06
Abstract: Timing pulses having a fixed relationship to a rotating part, for example a flywheel starter ring in the case of an IC engine, have been produced by the difficult and costly method of drilling a plurality of accurately positioned holes in the flywheel, sensing their passage past a transducer and generating a pulse in response to each passage. In this invention, the pulses are generated by a microprocessor 1, and their synchronisation with the rotation of the flywheel is checked each time one of the pre-existing accurately machined teeth of the flywheel starter ring passes a transducer and their period adjusted if necessary. A second transducer produces a reference pulse once per revolution at a position representative of the top dead centre position. From these pulses a number of pulse trains synchronised with the rotation of flywheel may be produced (Channels 1 to 8). <IMAGE>
