Title: Improvements in or relating to rotary duplicating machines
IPC: B41L11/00
Filed: 1957-11-27
Abstract: 858,196. Copying documents. RITZERFELD, W., and RITZERFELD, G. Nov. 27, 1957 [Dec. 6, 1956; April 24, 1957], No. 36976/57. Class 100(2) A rotary duplicating machine comprises a rotatable printing drum carrying at its periphery a pressure body in the shape of a cylinder segment for printing only a line or section of a text of a master sheet when attached to the drum so that the said line or section overlies the pressure body, and a counter-pressure roller co-operating with the pressure body but not with the periphery of the drum. Master sheets 106, Fig. 3, are fed from a box 49, by members 45, 44, 50 under the control of the drum, to grippers 109, so that a new master sheet is fed on each revolution, the grippers 109 being opened by a cam 187 to release the master sheets into a container 77. A pressure body 133 is carved on a sheet 132 secured in a slot 131 of the printing drum 43. A long copy sheet for listing is fed by frictional contact with the pressure body 133 and a counter-pressure roller 57. A moistening device 158 is operated by a cam 159. The trailing end of the sheet is clamped between jaws 172, 173 guided by a yoke 175 slidable on guides 177 fixed to the feed table 171. A spring-loaded extensible device 182, 183 urges the jaws to the right. A pawl 179 fixed to the jaw 173 co-operates with teeth of a rack 180 having different pitches of which the desired one is brought into operative position by a dial 181. In operation, the sheet is frictionally fed against the spring action of the device 182, 183, and when the passing of the body 133 releases the sheet, the spring device 182, 183 imparts a rearward feed movement to the sheet to the limit allowed by the pawl 179 and the next rack tooth, so as to close up successive texts on the copy sheet. When the last text has been printed, an abutment 184 opens the jaw 172 to release the sheet. The body 133 and sheet 132 can be removed, a master sheet inserted in the slot 131, and the roller 57 be adjusted by a lever 137 in order to print the complete text from the master sheet. In another form, Fig. 1, a web 146 from a spool 147 is fed forwards in the same way, and is held against unintentional movement when the moistening device 158 is raised by a roller on a spring-urged arm 157. Rearward feed of the web at the end of each cycle is produced by a cam 155 through members 153, 151, 150, 149, the member 149 carrying a roller 160 capable of rotation only counter-clockwise, so that it rolls over the web on leftward movement and frictionally moves it on rightward movement. Specification 845,324 is referred to.

Title: Automatic brakc adjuster
IPC: F16D65/54
Filed: 1956-12-04
Abstract: 815,015. Automatic adjusting mechanism for brakes. BENDIX AVIATION CORPORATION. Dec. 4,1956 [Dec. 9, 1955], No. 37055/56. Class 103 (1). In an automatic adjusting device for brakes in which an adjustably displaceable stop means is located responsibly to displacement of a pressure-responsive movable member in excess of a predetermined amount of lost motion, means are provided which protrude into and are embedded in the surface of the stop means for normally resisting movement thereof and furrowing a path in the surface when such a movement occurs. In the embodiment illustrated in Fig. 1 showing part of an aircraft disc brake, a pressure plate 20 is moved by an annular piston 14 slidably received in a cylinder bore 12 in fixed brake housing 10 and a series of automatic adjusting devices 22 are provided each comprising a pin or stem 24 secured at one end to the pressure plate 20 and having at its other end a nut and washer 32, 34. Surrounding the pin 24 is a sleeve 38 having an open end 40 and housing a helical spring 46. Clearance " D " denotes the clearance which is maintained between the rotatable and non-rotatable parts of the brake. A circular member 48 is fixedly secured to housing 10 and a number of spaced set screws 50 are threadedly received in circular member 48 and are embedded in the surface of sleeve 38. In operation, when piston 14 is moved to right, pressure plate 20 is displaced towards the right until the friction members are fully applied. If wear of the linings has taken place, the distance " D " will have been completely closed and further movement of stem 24 will, acting through shoulder 36 of washer 34, pull the sleeve towards the right against the resistance of set screws 50; the brake applying effort being sufficient to overcome the resistance offered by the set screws 50 which furrow paths 51 (Fig. 3) in the wall of sleeve 38. When the fluid pressure is released, the stem 24 is pushed towards the left by spring 46 through distance " D " until pressure plate re-engages the end 42 of the sleeve. A washer 54, serving as a oneway clutch, is provided to prevent movement of the sleeve when the aircraft wheel is retracted so that the weight of the brake may be carried through the adjuster without interfering with the adjustment mechanism. Fig. 4 illustrates the invention applied to the interior of a fluidpressure piston and cylinder device in which a stem 74 is secured at one end 72 to an end cap 63 screwed into cylinder 55 and set screws 94 are located in a ring 88 carried by the piston 60. The clearance between the shoulder 76 and the end 84 of the sleeve 78 represents the clearance in the brake and the adjusting mechanism operates in a similar manner to that described in the above embodiment.

Title: Improvements in and relating to the manufacture of secondary amines
IPC: C07C209/48
Filed: 1956-12-04
Abstract: Aliphatic or cycloaliphatic secondary amines containing from 8 to 22 carbon atoms are prepared by conducting in a closed circuit the steps of contacting in the liquid phase in a reaction zone in the presence of a hydrogenation catalyst a nitrile and/or primary amine containing from 8 to 22 carbon atoms with gaseous hydrogen at 150 DEG  to 250 DEG  C. and at a pressure of from atmospheric to 250 p.s.i.g.; continuously venting from the reaction zone a gaseous mixture of hydrogen and ammonia, the latter being formed during the reaction, at a rate of from 1 to 4 mols. of mixture per mol. of reactants per hour; passing the vented gas mixture to a separating zone and separating therefrom the ammonia; and passing the hydrogen back to the reaction zone.  The preferred starting materials are straight-chain aliphatic nitriles containing from 8 to 18 carbon atoms, such as the alkyl and alkylene nitriles derived from the fatty acids of fats and oils, e.g. tallow, coconut oil, soybean oil and cottonseed oil.  The cycloaliphatic nitriles derived from tall oil and rosin acids may be used.  The primary amines corresponding to and derived from the nitriles by hydrogenation may also be used. Specified catalysts are Raney nickel and copper-chromium oxide.  The amount of catalyst is generally about 0.4 to 3% by weight based on the weight of catalytic metal.  The presence of water should be avoided and the reactants and catalyst dried.  In an apparatus described the vented gas mixture is cooled to about 25-65 DEG  C. and then scrubbed in countercurrent with water to dissolve the ammonia. The presence of hydroxides and metallic soaps should be avoided.  The secondary amine may be bleached in situ during the reaction by incorporating an inert bleaching agent in the reaction mixture, e.g. 1 to 3% of fuller's earth, bentonite, kieselguhr or activated carbon.
