Title: Factice-like products
IPC: C09F5/00
Filed: 1959-12-15
Abstract: Factice-like products, which improve the extrusion properties of butyl rubber and which may incorporated in natural and synthetic rubbers in general to reduce aging, are obtained by reacting an ester of an unsaturated hydroxy fatty acid sich as triricinolein with an inorganic chloride, of an element of Group IV of the Periodic System, especially the tetrachlorides of silicon, titanium and tin, the molar ratio of ester to chloride being preferably 1,3-2,5 : 1 (see Group III).ALSO:Factice-like products are obtained by reacting an ester of an unsaturated hydroxy fatty acid, such as triricinolein, with an inorganic chloride of an element of Group IV of the Periodic System, especially the tetrachlorides of silicon, titanium, or tin, the molar ratio of ester to chloride being preferably 1.3 to 2.5:1.  The reaction may be carried out either merely by mixing and stirring the reactants, or in the presence of an inert diluent such as a chlorinated hydrocarbon, e.g. trichlorethylene. Volatile products of the reaction may be removed by passing air at ambient temperature or at 110-130 DEG C. through the mixture. Preferably, after air at ambient temperature has been passed for some time the reaction mixture is heated by raising the temperature of the air being passed to 110-130 DEG C.

Title: Lift control systems
Inventor: MINNS GEORGE ERIC
IPC: B66B13/14
Filed: 1966-09-26
Abstract: 1,147,159. Lift door control systems. DEWHURST & PARTNER Ltd. 1 Sept., 1967 [26 Sept., 1966], No. 42837/66. Heading B8L. A lift door control system comprises a first switch device (consisting of a transistor controlled relay) operable to one state to permit opening of the door if closed and to prevent closure if open, and to another state to cause closure or prevent opening, a second switch device (transistors) responsive to a call for the car to operate the first device to said one state after a delay, and a third switch device (transistors) responsive to the car being other than stationary at a landing immediately to operate the first device to said one state if the door is closed and to the other state if the door is open. Thus, if the lift is parked (doors closed) when a call is made opening of the doors is delayed (for two seconds) to enable the lift to move if necessary; once on the move the first switch device is immediately set to the state which allows the doors to open immediately the lift comes to rest. Further switching transistor and timing circuits (R-C type) are described whereby the doors are automatically closed a prescribed time after being opened or immediately a call is made, but if they fail to close after, say, 40 seconds, they are parked open. If the doors fail to open, or the door motor takes excessive current, the motor is switched off and all calls are cancelled. A second relay establishes preference for car calls over landing calls when the doors are not shut or the car is moving, and this is maintained for a short time after the doors have closed and after the car has arrived at a landing. If the lift fails to start when the doors are closed and a call is registered the doors are opened and all calls cancelled. The doors may be opened by a photo-electric call device, and will also open if a " safety edge " is actuated. It is stated that operation of a door opening contactor cancels all calls for the lift. A " special purpose " switch is provided to hold the doors open when required.

Title: Production of continuous filament yarn
IPC: D01H7/02
Filed: 1972-09-25
Abstract: 1400816 Multifilament yarns PHILLIPS FIBERS CORP 25 Sept 1972 [29 Sept 1971 22 Nov 1971] 44206/72 Headings D1F and D1W The production of a continuous filament yarn comprises, in a continuous sequence, the steps of withdrawing from a source a substantially twist-free, undrawn yarn of continuous filaments, introducing a true twist into the yarn, drawing the twisted yarn, thermally relaxing the drawn yarn and winding the yarn into a package without further twisting. The twist imported to the yarn is sufficient to provide in the final yarn a twist of from one quarter to two turns per inch. As shown, Fig 2, a continuous filament yarn 1 is withdrawn from package 2 in ion 4 which is rotated to twist the yarn. Package 2 may be formed by winding as spun yarn from a spinneret. The yarn is drawn at least 200 per cent, preferably at least 300 per cent, between feed rolls 14, 15 and draw roll 17 while being passed around snubbing pin 16. The yarn is optionally heat set by being passed, tensioned bent undrawn, around heater 19 to roll 23, and is heat released while passing around heater 25 to roll 28 whose surface speed is at least 2 per cent, and preferably at least 5 per cent, less than that of roll 23. The yarn is then wound on a surface driven package 33 or in a precision winder. Heaters 19, 25 need not be contact heaters. Alternatively, Fig 3, the yarn is twisted in a 2-for-1 twister 40 and is drawn at least 120 per cent between Godet rolls 46, 51 while being wrapped about snubbing pin 50 at least once, and preferably at least three times, in the same direction as the direction of yarn twist. The yarn is passed to Godet roll 56 while being wrapped about vertical heater 53, and is then wound on package 60. For polyamide filaments, the surface speed of roll 56 is at least 4 per cent less than that of roll 51, and the yarn it heated by heater 53 to 120‹C to 300‹C to maintain a tension in the yarn between rolls 51, 56 of at least 0.1, and preferably 0.25 to 0.50, grams per denier. These conditions are said to reduce residual shrinkage and maintain a high initial modulus of the polyamide yarns. Roll's 56, 57 may be omitted. The filaments may comprises other thermoplastic materials, e.g. polyesters.

A strip conductor coil 30 is wound from conductive strip 31 and insulating strip 39 on an insulating core 32. The supply rolls 40, 41 are mounted on free wheeling rollers 44, 45 respectively and the strips pass over turning bars 46, 47 respectively. Each roller is fitted with an adjustable spring-loaded brake (201), (202), (203) (Fig. 4, not shown) which are connected to lever arms (48), (49) loaded by adjustable springs 52, 53, respectively and on which are respectively mounted the bars 46, 47. A mandrel 63 is advanced by a fluid pressureoperated piston-rod 64 into a retainer 96 of a hopper 70 where it picks up a core 32. The mandrel is withdrawn and rotated to the station 67 whereupon it is again advanced, a clutch member (81) (Fig. 18, not shown) on the mandrel engaging a mating clutch member (82) on the end of a drive shaft 60. A taping head 139 holds the strips 31, 39 together on a table (138) (Fig. 24, not shown) and applies a length of adhesive tape (141) to the strip (31) and to the core (32) (Fig. 25, not shown). The shaft 60 is rotated to wind the coil and when almost fully wound is stopped. Two parallel strips of contact material 103 are advanced by members 109 so as transversely to overlie the strip 31 to form leading and trailing contacts (33), (34) respectively. The underneath of the strips 103 is cleaned by brushes 119. A die block 57 is lowered driving a rod 123 downwardly until it abuts a block 131 whereupon projections 134 cold weld the contact strip to the strip 31. Simultaneously a member 135 perforates the strip between the contacts (Fig. 2, not shown). The strips are further advanced until the trailing contact (34) is under the taping head 139, which is then lowered to hold the strips against the table 138 (Fig. 21, not shown). A second taping head 140 is lowered on to the coil to apply a tape thereto and the shaft 60 is again rotated so that the strip is ruptured at the perforations. The mandrel 63 is moved to the station 68, where its resistance is checked and if it is unsatisfactory it is removed from the mandrel by a stripping mechanism 72. If the coil complies with the test it is removed from the mandrel at station 69 by a stripping mechanism 73, where it falls into a hopper.
