Title: Process for improving the performance of synthetic filaments in textile operations by application of a textile treating composition
Inventor: ROBERTS THOMAS EARL
IPC: D06M15/647
Filed: 1968-04-22
Abstract: 1,246,134. Applying an antistatic treating composition to artificial filaments. E. I. DU PONT DE NEMOURS & CO. 24 March, 1969 [22 April, 1968], No. 18929/68. Heading B5B. [Also in Division C3] Synthetic and cellulose derivative filaments are rendered more processable by applying to them an antistatic textile treating composition comprising a polysiloxane/polyoxyalkylene copolymer and a partial phosphate ester. The copolymer may consist of one or more siloxy groups and one or more oxyalkylene groups wherein n and m are at least 3, R and R<SP>1</SP> are the same or different hydrocarbon groups having 1 to 6 carbon atoms and X is an integer of 2 to 4. Especially preferred copolymers contain no Si-O-C bonds. The copolymer may have the formula wherein m is 3 to 100 and R is hydrogen or an alkyl, aryl or acyl group. When R is hydrogen, m may be less than 60. The partial phosphate esters may have the formula wherein Y is 1 or 2, M is a monovalent cation and R is an organic radical optionally containing oxyalkylene groups. The textile treating composition may also contain a lubricant and/or a surface-active agent. In the example, the composition consists of a mixture of 68À5 parts (by weight) of isocetyl stearate, 12À5 parts of the partial glyceryl ester of oleic acid, 15 parts of the potassium salt of a partial phosphate (prepared from a mixture of fatty alcohols consisting chiefly of lauryl alcohol) and 4 parts of a polysiloxane/polyoxyethylene copolymer containing 88% of an ethylene oxide block and 12% of a dimethyl siloxane block having a trimethyl siloxy end cap. The mixture is emulsified with water to provide an aqueous emulsion containing 20% by weight of solids and is applied to freshly spun polyethylene À terephthalate filaments to provide them with a coating of about 0À8% of the residual composition and the filaments are drawn at a draw ratio of 2À8 at a speed of about 2500 metres per minute. The filaments to which the composition is applied may consist of elastomers (e.g. segmented polyurethanes), acrylic polymers, polyamides, polyesters, polyolefins, copolymers of these polymers, or cellulose esters.

Filed: 1973-04-19
Abstract: 1413005 Fuel injection pumps STANADYNE Inc 19 April 1973 [24 April 1972] 19091/73 Heading F1A The rotor 14 of a rotary distributor fuel injection pump is driven by a shaft 46 axially urged by a spring 80 so that a tang 44 on the shaft engages a slot 42 in the rotor. The spring 80 acts between a retainer ring 82 and a ball bearing 72, 74 fixed to the shaft 46 and slidably received in a recess 76 in the pump housing 10. Thus, in operation of the pump, the spring 80 prevents oscillation of the shaft 46 thereby (a) reducing wear between the surfaces of the slot 42 and tang 44 and (b) inhibiting pressure pulsations in a cavity 66. Pressure pulsations in the cavity 66 are undesirable because they affect operation of centrifugal weights 70 controlling an inlet metering valve 22 and also the quantity delivered by the pumping pistons 36, since the radial outer ends of the latter are pressurized by fluid in the cavity 66. A rotary vane pump 18 supplies fuel to the inlet of the valve 22 via a passage 20.

Title: Methylphenylsiloxanes
IPC: H01B3/46
Filed: 1963-05-14
Abstract: The invention comprises the cyclic polysiloxanes of formula <FORM:1002663/C3/1> which are prepared by the reaction of hexaphenyltrisiloxane 1,5-diol with 1,3-dichlorotetramethyldisiloxane or 1,5 - dichlorohexamethyldisiloxane in the presence of an excess of a hydrogen halide acceptor, e.g. pyridine or a tertiary amine such as triethylamine or dimethylaniline. The use of an inert solvent is desirable, e.g. ether, tetrahydrofuran, or benzene. Room temperature is adequate.  The examples describe the preparation of both compounds and their polymerization, at 110 DEG  and 210 DEG  C. respectively, using a 1% dispersion of KOH in octamethylcyclotetrasiloxane as catayst and the curing of the first polymer by electron irradiation to give a rubber.  The polymers can be converted into rubbers by conventional filling and curing.  Suitable fillers are carbon black, silica aerogel, or fume silica.  These fillers may be coated with a solution of one of the above cyclic compounds and used as fillers for normal silicon rubbers.

Abstract: 421,895. Safety razors. GILLETTE SAFETY RAZOR CO., 15, West 1st Street, Boston, U.S.A. July 6, 1933, No. 19216. Convention date, Oct. 24, 1932. [Class 30] The blade 50, which has the usual closed medial slot 51, is slidable endwise through the means which connect the clamping- and guard-plates 10, 20, whilst these latter members remain at all times connected by the said means and in superposed relation. The connecting-means comprise a rotatable disc 40 having flanged parts 44, 45, engaging an undercut arcuate groove 13 in the clamping-plate, and separated by a gap 43, which is large enough to receive the end of the slotted blade 50. Endwise insertion of the latter turns the disc 40 to change-over from the flanged connection 44, Fig. 9a, to 45, Fig. 9b, the blade-end remaining in the gap 43 during the change - over. A spring - pressed plunger 48 snaps the disc 40 into its extreme positions. The blade can be adjustably flexed, the disc 40 being pivoted in the forked end of a plunger 36, retained, for limited axial movement in the handle, by a rotatable end-nut 33, itself axially retained by an offset cross-pin 34. The guard carries a blade-locating ball 24, which forms an antifriction bearing for the blade during its insertion. Blade-location is further effected by a guard-rib 23 and corner projections 15 at one end of the clamping-plate. These projections 15 serve also to unbalance the clamping-plate so that, when the clamping pressure is released, it tilts on the connecting- disc 40 and provides a wider gap between the clamping- and guard-plates at the end which receives the blade. At this end also the plates have arcuate finger-recesses 12, 25 cut therein. In the form shown, outward endwise movement of the plunger 36 is limited by a removable screw 39, but in a modification the screw 39 is replaced by a resiliently-mounted eccentric collar engaging a reduced part of the plunger 36 and movable, by depression of an external button, to a concentric position to allow the plunger to be withdrawn from the handle.

Abstract: 293,462. Hazeltine Corporation, (Assignees of Wheeler, H. A.). July 7, 1927, [Convention date]. Thermionic amplifiers and detectors.-Relates to amplifiers with automatic volume control. Fig. 4 shows high-frequency neutralized amplifiers 90, 91, a detector 94, and audio-frequency amplifiers 105, 108. The grid bias applied to the amplifier 90 is varied in accordance with the rectified current in the detector circuit to control the volume. A switch 115 is provided to cut out the volume control and resonance is indicated by a milliammeter in the plate circuit of the amplifier 90. The combination of resistance 101 and battery 100 is such that the point 112 is negative with respect to the filament in normal operation. A resistance -capacity coupling, Fig. 5 (not shown), may be substituted for the transformer 99. A rheostat 106 is provided to enable the volume to be manually adjusted, the transformer 107 being shunted by a resistance 110 to avoid loss of low frequencies when the impedance of the amplifier 105 is increased by dimming the filament. The automatic volume control may be applied to more than one of the high-frequency amplifiers and the detector may comprise a two-electrode valve to secure direct proportionality between the input and output. In a further modification, Fig. 6 (not shown), the batteries are dispensed with and the supply is taken from the mains. Fig. 7 shows a mains operated receiver employing a two-electrode valve 66 as a detector in which control is applied to the grids of amplifiers 84, 86. The valve filaments are series connected and tappings taken so that correct grid bias is obtained for all valves. Auxiliary volumecontrol is effected by rheostat 130 adapted to shunt variably the filament of the audio frequency amplifying valve 74, while resistance in the series circuit is varied to prevent current change in the remaining valve filaments. The difference in grid bias applied to amplifiers 84, 86 due to differences in filament potentials is corrected by supplying additional plate voltage to the amplifier 84.
