Title: Crease-resistant fabrics
IPC: D06C29/00
Filed: 1960-07-25
Abstract: 897,555. Fabrics, finishing. MONTECATINI SOC. GENERALE PER L'INDUSTRIA MINERARIA E CHIMICA. July 25, 1960 [July 30, 1959], No. 25804/60. Class 42 (1). In a process for obtaining crease-resistant fabrics based on polyolefin fibres the fabric is subjected to the action of heat whilst under tension. The fibres may be prepared from crystalline polymers of alpha-olefins obtained with the aid of stereoscopic cataylsts and they may be in admixture with other natural, artificial or synthetic fibres. The polyolefin is preferably polypropylene and the temperature range is 100-140‹ C., preferably 120‹ to 135‹ C. and the time from 10 seconds to 120 minutes, preferably 5 to 10 minutes.

Title: Process for the production of highly elastic cross-linked diisocyanate-modified polyesters
IPC: C08G18/68
Filed: 1954-09-06
Abstract: A highly elastic product is made by reacting a mixture of a saturated and unsaturated substantially linear polyester each containing hydroxyl groups with a quantity of a di-isocyanate in excess of the amount capable of reacting with the hydroxyl end groups of the polyester and subsequently cross linking the reaction product by reacting it with an amount insufficient to react with all the isocyanate groups, of a compound which has at least two hydrogen atoms which can react with isocyanate groups. Specified di-isocyanates are 1.5 - naphthalene -, p - phenylene -, diphenylmethane- and toluylene di-isocyanates.  Specified cross-linking agents are butylene glycol, dihydroxyethyl - 1.5 - naphthalene ether, 3.3-dichlorobenzidine and amino-ethanol.  In examples a mixture of ethylene glycol adipate (acid number 1.8, hydroxyl number 56) and ethylene glycol adipate maleate (acid number 2, hydroxyl number 56) was dehydrated by heating under vacuum.  Then 1.5-naphthalene- or p-phenylenedi-isocyanate was added and when the heat of reaction had finished 1.4-butylene glycol was stirred in and the mixture poured into moulds. Specification 754,604 is referred to.

Filed: 1961-02-22
Abstract: 973,494. Change speed control: valves. BORG-WARNER CORPORATION. Feb. 22, 1961 [March 4, 1960], No. 26094/63. Divided out of 973,493. Headings F2D and F2V. A governor valve providing pressure variable in accordance with vehicle speed in a fluid pressure control system for an automobile change speed gear of Specification 973,493 has a three-stage action for extension of its speed range. The valve comprises radially bored casings 711, 712 fixed to a casing 710 keyed on a change speed gear output shaft 11. The casing 711 has an inlet (main line pressure) port 719, exhaust ports 721, 722 and an outlet port 720 connected to an inlet port 736 of the casing 712 which has an outlet (governor pressure) port 737 and exhaust ports 738, 739. A sleeve 714 having different sized lands 723, 724 slides within the casing 711. A centrifugal weight 715 piloted in the sleeve 714 acts thereon through a stem 716, a cap 717 and a spring 728. A piston 731 having different sized lands 733, 734 slides within the casing 712 and is urged outwardly by a spring 732 and centrifugal force. In operation, outward movement of the sleeve 714, acted on by the weight 715, admits main line pressure which then acts on the different lands 723, 724 to tend to move the sleeve inwardly to close the port 719 thereby providing an output pressure regulated as a function of output speed and shown in Fig. 2 by the line OA. When the cap 717 bottoms out against the casing 711 any increase in the centrifugal force acting on the weight 715 is no longer effective to move the sleeve 714, and the centrifugal force acting on the sleeve 714 itself continues to provide an output pressure regulated as a function of output speed and shown by the line AB. For all speeds lower than point B, the spring 732 and centrifugal force on the piston 731 act to provide a continuous communication between the inlet and outlet ports 736, 737 of the casing 712. However at point B the force due to pressure on the different lands 733, 734 tends to move the piston 731 inwardly to close the port 736 thereby providing an output pressure as shown by the line BC. Specification 973,495 also is referred to.

[Class 38 (v)] In an overload protective system for an electromagnetically operated switch b, control contacts operated by the protective device are adapted to control both the operating coil d of the switch and an auxiliary circuit containing an indicator, such as a discharge lamp m. In the arrangement shown, the control contacts i, k are normally held closed, against the action of a spring h, by a latch f. The overload device comprises three bimetallic strips c included in the phase wires R, S, T, the strips being connected to a pin or rod e adapted to release the latch f in the event of an overload in any of the phase wires. When the control contacts are closed the indicator lamp m is short-circuited, and the switch b can be closed by closing a switch n, which may be located at any desired distance from the switch b. On overload, the contacts i, k separate and the lamp m is thrown into circuit with the coil d, the current being reduced to a value which is insufficient to hold the switch b closed but sufficient to light the lamp. The control contacts are reset by a push-button l.

Upon de-energization of the magnet and withdrawal of the armature, the core remains in this aligned position. In a modification, Fig. 5 (not shown), the extensions 6 of the core are replaced by an end plate (14) having curved edges. The core 2 is rigidly connected to the movable member 13 of a switch.
