Title: Process and apparatus for melt spinning thermoplastic yarn
IPC: D01D5/08

Abstract: 1,222,717. Melt-spun fibres with improved uniformity. FMC CORP. 19 Sept., 1968 [4 Jan., 1968], No. 44630/68. Heading B5B. Melt-spun fibres and filaments are made by extruding a plurality of molten synthetic polymer filaments from a multi-orifice, preferably circular, spinneret assembly downwardly into a cooling gaseous medium, preferably directed radially inwardly and horizontally across the filaments over an arc of about 180 degrees, thus substantially solidifying the filaments; directing a cushion of a steady current of a gaseous medium against the substantially solidified filaments, the current emanating from a relatively narrow source positioned in the filaments' path, substantially perpendicular thereto, and having sufficient force to prevent contact of the filaments with the current source; and forwarding the filaments, the path of which may change direction at the gaseous cushion. At least one other cushion of gas may be directed against the filaments at a position no farther upstream of the filament path than the first-mentioned gaseous cushion. The front wall of the preferred enclosure for the cooling gaseous medium, which has inlet means for a supply of the cooling gas, has a longitudinally concave foraminous surface extending into the enclosure, the other walls having edges substantially coextensive with the concave surface, whereby the gaseous cooling means co-operates with the spinneret assembly and partially surrounds the extruded molten filaments. Filament steadying means are provided which may comprise a closed tube having means to receive pressurized gas, preferably a straight metallic tube closed at one end and adapted to receive pressurized gas at the other end, at least a portion of which comprises a microporous section from which the cushion of gas emanates. Figs. 1, 2 and 3 (2 and 3 not shown) show schematic side views of three embodiments of the invention, Fig. 4 (not shown) shows quenching apparatus and Figs. 5 and 6 (Fig. 6, not shown) show two suitable gas cushion supply means. Polypropylene filaments are exemplified; suitable polymers are polyester resins (e.g. polyethylene terephthalate) isotactic polypropylene resin, polyamide resin (e.g. polyhexamethylene adipamide and polycaprolactam), polyvinyl chloride resin, polycarbonate resin, and polyphenylene oxide resins, as well as mixtures of these resins.

Title: A process for lowering the acid number of alkyd resins
IPC: C08G63/48
Filed: 1964-11-09
Abstract: The acid number of an alkyd resin which may be considered to derive from a polycarboxylic acid, a polyhydroxy compound, and a monocarboxylic acid is lowered by reacting the resin with a monoepoxy compound having a boiling point above 100 DEG  C. and containing a terminal epoxy group as the sole reactive group.  An epoxyalkyl ester of a monocarboxylic acid is the preferred type of epoxy compound. This monocarboxylic acid may be aliphatic, cycloaliphatic, aromatic or mixed aromatic-aliphatic, e.g. lauric, myristic, palmitic or stearic acid, but is preferably an aliphatic monocarboxylic acid having a tertiary or quaternary a  carbon atom, e.g. one prepared by reacting an olefin with formic acid or with carbon monoxide and water in the presence of a liquid acid catalyst Monoglycidyl compounds are preferred.  The alkyd resin is preferably one in which the monocarboxylic acid component is unsaturated, and preferably has an acid number initially below 50, and finally below 25.  The reaction with the monoepoxcy compound takes place below 300 DEG  C., preferably at 150-250 DEG  C.  In examples a mixture of glycidyl esters of C9- 11 branched monocarboxylic acids are heated at 240 DEG C. with a commercial castor oil/phthalic anhydride alkyd resin in xylene, and with a phthalic anhydride/pentaerythritol/linseed oil or a phthalic anhydride/glycerol/linseed oil resin in a low aromatic white spirit.  The products are compared with the untreated resins by determining the drying times of films of solutions of the resins, with naphthenate driers, in low aromatic white spirit, and by determining the miscibility of the resins with linseed stand oil.

Abstract: 1340392 Electro-erosion CINCINNATI MILACRON Inc 4 Oct 1971 [15 Oct 1970] 46128/71 Heading B3V [Also in Division G3] The flow rate of dielectric through an electroerosion machining gap is controlled in dependence on the gap impedance. In one embodiment, Fig. 4, a bridge circuit 42 containing a photon coupled isolator 58 is connected across the machining gap and is energized between machining pulses by means of a D.C. source 40. The output signal from the circuit 42 which is dependent on the magnitude of the gap impedance, is fed to a transistorized amplifier 44, the output signal of which controls an oscillator 46 comprising an astable multivibrator. The output pulse from the oscillator 46 is fed to a motor drive 54 which controls the speed of a motor 52 for a pump 50 which supplies the dielectric 15 to the machining gap, through the workpiece 12. The motor 52 may be replaced by an hydraulic motor and servo-valve. In other embodiments, the dielectric may be supplied by one or more pumps possibly in combination with one or more valves. In another embodiment (Fig. 5, not shown), the flow rate is altered to a particular value only when the gap impedance increases or decreases a predetermined amount above or below a normal impedance value. In this embodiment, the bridge circuit 42 contains three photon coupled diodes (80, 82, 84), each of which produces an output in response to a predetermined gap impedance value. In alternative embodiments, the dielectric is passed through the electrode (Fig. 1, not shown) or through a separate tube having its outlet adjacent the gap (Fig. 2, not shown).

Title: Anti-lock brake control systems

Filed: 1973-10-04
Abstract: 1388989 Anti-skid control systems GENERAL MOTORS CORP 4 Oct 1973 [1 Nov 1972] 46315/73 Heading F2F In an anti-lock control system for at least one braked vehicle wheel, a differentiated wheel rotational speed electrical signal is compared with a deceleration reference signal continuously variable as a function of wheel speed in a uniform manner therewith over a predetermined range, the difference therebetween being integrated and compared with a threshold value to form a control signal to a modulator. The rotational velocity of one or more braked wheels is sensed by a wheel or transmission mounted tachogenerator which supplies a sinusoidal electrical signal along lines 14, 16 through resistors to an amplifier 62 which acts on differential input currents. A feedback resistor 66 and a capacitor 68 provide an output of similar frequency in the form of a square wave. An amplifier 72 with a feedback capacitor 74 and a resistor 78 converts the frequency signal to a voltage output which passes through a diode 76 whose forward breakdown voltage causes signals representing 3 m.p.h. or less to be inhibited; also signal ripples are inhibited. This signal is differentiated by a capacitor 84 and compared at 30 with a signal formed of a constant value, as determined by a positive potential-coupled resistor 86, and a wheel speed dependent value, as determined by the resistor 88. The compared signal is integrated by a capacitor-coupled amplifier 32 and compared with threshold values by circuitry 36. Here, an amplifier 94 receives the signal as one input and incorporates a feedback resistor 98; a negative input is resistor-coupled to a transistor 104 which is conductive during steady-state operation to provide a reference value at this input. If the integrated signal (velocity error signal) exceeds an equivalent of 2¢ m.p.h. the amplifier switches to provide an output through a resistor 114 to an output driver 40 comprising coupled transistors 116, 118 which are rendered conductive to energize a solenoid 44<SP>1</SP> of a valve, actuating the modulator which is responsive to air pressure and vacuum, the latter being controlled by the valve. Due to hysteresis in the resistor 98 the output is retained until the velocity error signal drops below an equivalent to 1 m.p.h. Then the transistor 104 is cut-off for 130 milliseconds to cause additional current flow to the reference input of the amplifier 94 to inhibit possible noise signals.
