Title: Method for winding band-like materials and driving mechanism for executing said method
IPC: B65H23/195
Filed: 1951-08-22
Abstract: 700,332. Variable-speed gearing. SCHMID. A. Aug. 22, 1951 [Aug. 22, 1950], No. 19831/51. Class 80 (2) The shaft 3 of a winding machine for strip material is driven through V-belt expanding- pulley gearing, the slidable tread 8 of the output pulley being moved in accordance with the deflection of a torsion spring 12 by which a sleeve 10, carrying the spring-pressed treads 4, 5 of the input pulley, is connected to the driving shaft 2, so that the speed of shaft 3 is determined by the torque. Relative rotation between sleeve 10 and shaft 2 produces, by a pin 16 engaging a cam groove 15a, axial movement of sleeve 10 so as to bring one or other of two flanges 18, 19 into engagement with a feeler roller 20 on a shaft 22. The resulting rotation of shaft 22 produces, through gears 28, 29, clutch 32, gears 33, 34, shaft 35, gear 36 and rack 37, movement of tread 8. As the diameter of the wound roll increases during the winding operation, with consequent increase of torque, the speed of shaft 3 is thus progressively reduced. Prior to a winding operation, clutch 32 is disengaged by means of a rod 45 and the outward position of tread 8, for maximum winding speed, is set by an adjustable abutment screw 42, after which the clutch is re-engaged. The lower bearing 23 of shaft 22 is carried on one arm of a lever 21, the other arm of which is held between opposing springs 25, 26 on a pin 27. The latter may, as shown, be adjustably threaded in the casing 1, to give constant adjustable winding tension. In addition, however, the pivot 50 of lever 21 may be on an arm 75, Fig. 5, engaged by a cam member 70 rotating with shaft 35, the arrangement being such that the winding tension is reduced as the winding progresses. The member 70 is conical and adjustable axially on shaft 35 so that the reduction in tension may be varied. In a modification, with the pivot 50 fixed, the end of the pin 27 engages the member 70.

The parts are assembled by inserting the arms 23 through the aperture 22 in the plate 19 and then through slots 33 in the ratchet plate 29 as it is located by a pressed up detent 20 over the plate 19, the spring 26 then being inserted between the arms 23 the upper extending parts of which are subsequently pressed over at 25 to maintain the spring 26 captive. The upper ends of the arms 23 are then connected to the - lower end 15 of the sash balance spiral member 15 by a pin 24. Adjustment to increase the tension of the spring 11 is accomplished by inserting the bit of a screwdriver into a slot 28 in the adjusting plate and turning it anti-clockwise, Fig. 3, to the desired amount. If the tension of the spring 11 is to be decreased, the screwdriver is first moved upwards to disengage the pawls 21 from the notches 30, the coil spring permitting the release of the spring to take place in half turn stages anti-clockwise.

Filed: 1925-08-10
Abstract: 252,578. Lane, J. D. Aug. 10, 1925. Making paper tubes. - -Relates to tube-making machines of the type in which sheets of paper coated with adhesive are coiled on a rotary mandrel which is encircled by a device for applying pressure radially inwards, with means for releasing said pressure when the tube is formed, and ejecting the tube. According to the invention the radial pressure is applied by a flexible resilient sheet metal gripper 14 which is welded to a strut 19 oscillatably mounted on a fixed cross-bar 16. The rear end of the gripper is secured to a bar 22 pivoted at 21 which exerts a pull on the gripper by means of a spring 26. The bar 22 is controlled by a roller 28 and rotary cam 30. When the projection on the cam 30 is in contact with the roller the gripper releases its pressure on the mandrel 12. Paper is introduced between the gripper and roller in the relaxed position and is coiled continuously under pressure until relaxed by the timed rotation of the cam 30. The mandrel is then moved endwise clear of the gripper for the removal of the formed tube. Rotary cutters may be provided for severing the tube into lengths before the endwise movement takes place. To prevent over expansion of the gripper, fixed arms or formers 33 are provided concentric with the mandrel. The mandrel 12 has a series of serrated collars 12<a> for engaging the paper with smooth spacing collars 12b therebetween. Freely rotatable soft metal collars 12<c> are provided opposite the rotary cutters 11. The outer bearing 35 is operable to release the mandrel and permit endwise movement thereof. The collars 12<a>, 12b are fixed to the mandrel but can be removed and replaced by collars of different lengths for making tubes of different lengths.

IPC: G21C1/00
Filed: 1967-05-01
Abstract: 1,222,824. Controlling reactors. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. 1 May, 1968 [1 May, 1967], No. 20133/67. Heading G6C. In a pulsed reactor, the reactivity is controlled by oscillation of the cooling moderating liquid relatively to the fixed fuel elements. As the reactor heats, the gas in space 5, Fig. 1, expands and the fluid moderator 4 is expelled from the channels 3 surrounding the fuel 2 and the reactor ceases to be critical. As the core temperature falls the gas contracts, the moderator level rises and the core again becomes critical and reheats the gas to retrace the cycle. The core comprises enriched 235U, helium gas, and water as the coolant moderator. The duct 8 contains mercury and functions as a magnetohydrodynamic generator. Control of the reactor may be effected by adjustment of the pressure at P which controls the moderator level in the core. If pressure in the reactor fails, mercury will enter as a poison and terminate the reaction. To produce mechanical power, the gear motor 8, Fig. 9, is rotated by the flow of an oil moderator controlled by the valves 11, 12, 13 and 14.

Filed: 1929-07-02
Abstract: 314,871. Standard Oil Development Co., (Assignees of Haslam, R. T.). July 3, 1928, [Convention date]. Hydrocarbons, cracking; hydrogenation, destructive.-Oils and fluent carbonaceous materials are cracked and destructively hydrogenated in a cyclic process in which the heavy products from the cracking stage are destructively hydrogenated and the heavy products from this stage are returned to the cracking stage, products of low boiling point being recovered continuously from each stage. In a modification, the oils are first hydrogenated and the heavier products are then cracked, the heavier products from the cracking operation being again hydrogenated. The apparatus used is similar to that described in Specification 304,301. The crude oils are passed through a pipe 1 and heater 2 to a storage tank 4 from which oil is pumped as required through a cracking coil 7 to a digester drum 8. The cracked products are withdrawn through a valve 10 to a rectifying tower 3, the light hydrocarbons passing off through a pipe 11 to the usual condensers 11<a>.

Title: Improved treatment of mixed organic esters of cellulose
IPC: C08B3/24
Filed: 1932-07-18
Abstract: The solubility characteristics of acetone-soluble mixed organic esters of cellulose are changed by treating the esters with a hydrolyzing agent.  Particularly useful in the production of films and filaments are the originally acetone-soluble and subsequently hydrolyzed mixed esters of cellulose, the acyl content of which comprises at least 15 per cent of fatty acid radicle higher than acetyl (calculated on the weight of the mixed ester before hydrolysis).  Mixed esters specified are the acetate-propionate, acetate-propionate-butyrate, acetate-butyrate, acetate-stearate, and acetate-laurate, obtained, for example, according to the process of Specification 287,880, [Class 2 (ii), Cellulose].  A dilute mineral acid is preferred as the hydrolyzing agent, particularly when used in the presence of a sufficient quantity of organic acid to prevent precipitation of the cellulose ester.  The hydrolysis may be carried out at about 100 DEG  F. for from 1 to 360 hours.  The "precipitation value" of the hydrolyzed ester, which is defined as the percentage of ester which from an acetone solution thereof, will be precipitated in a mixture of 40 per cent of water and 60 per cent of acetone by volume, is preferably above 85 per cent.  The following examples are given:--(1) A reaction mixture comprising fully esterified cellulose acetate-propionate, propionic acid, acetic acid, and sulphuric acid is diluted with aqueous acetic acid and heated to 100 DEG  F. (2) A reaction mass comprising fully esterified cellulose acetate-butyrate, butyric acid, acetic acid, sodium acetate, and sulphuric acid is diluted with aqueous acetic acid and kept at 100 DEG  F.  Figures are given showing the effect of hydrolysis on solubility in various solvents, and the flexibility of films produced from the esters at various degrees of hydrolysis.  The products may be employed in the production of filaments, films, plastics, lacquers, &c. Specifications 219,926, 313,408, [both in Class 2 (ii), Cellulose &c.], and 388,303 also are referred to.  The Specification as open to inspection under Sect. 91 includes processes for hydrolyzing mixed esters of cellulose other than acetone-soluble esters.  This subject-matter does not appear in the Specification as accepted.
