Patent GB-649980-A (GB)
Title: Improvements in and relating to the production of aliphatic amines
Filed: 1947-12-19
Abstract: Amines are prepared by reacting an aliphatic alcohol containing at least three carbon atoms with ammonia in the presence of a catalyst comprising basic aluminium phosphate at elevated temperature.  The basic phosphate is defined as a basic salt intermediate the normal salt and the hydroxide or oxide such as is described in Specification 528,987.  The amines may be prepared by reaction at pressures up to 360 atmospheres gauge and at temperatures preferably above 250 DEG C., more preferably within the range 350 DEG  to 450 DEG  C.  The ammonia may be reacted with an alcohol alone or in the presence of amines which suitably may be a portion of the reaction products of a previous run; by providing suitable proportions of such amine or amines in the initial reaction mixture further production of the identical amine or amines is suppressed.  The reaction is preferably carried out in the presence of water whereby dehydration of the alcohol to olefine is suppressed; the use of superatmospheric pressure has a similar effect.  The process is particularly suitable for the treatment of alcohols having up to 8 carbon atoms.  Examples describe the interaction of ammonia and isopropanol, n-butanol or isobutanol at 350 DEG  C. and 200 atmospheres, in a converter packed with a basic aluminium phosphate catalyst prepared by reacting aqueous aluminium phosphate with an aqueous soda ash sodium phosphate solution, removing the precipitate, washing, drying and pulverizing it and finally admixing with 2 per cent graphite, compressing into tablets and calcining at 450 DEG  C.  The monoamines predominate in the resulting mixture of mono-, di- and tri-amines. Specification 572,898 is referred to.  According to the Provisional Specification, amines are prepared by reacting any aliphatic alcohol with ammonia in vapour phase in presence of a dehydrating catalyst comprising basic aluminium phosphate at elevated temperature and an additional example illustrates the production of ethylamines from ethanol.

Title: Fluid pressure means for controlling movement of a body
IPC: B23Q5/26
Filed: 1961-09-20
Abstract: 939,766. Fluid-pressure servomotor control systems. MECANORGA S.A. Sept. 20, 1961 [Oct. 3, 1960], No. 33647/61. Class 135. A movable member 1, e.g. a tool carriage, is movable in slides 2 of a frame 3, which movement is controlled by a hand or automatically actuated means 4 and effected by a piston 5, the pressure of compressible fluid supplied thereto being determined by the means 4. The latter includes a tube 9 slidable relative to the end 8 of the means 4 and carried by the member 1, the tube 9 having an enlarged head 7 and a shoulder 22 equal in diameter to the head 7, the shoulder being disposed in chamber 21; the tube 9 and chamber 21 are open to a supply pipe 10 depending upon the distances between the head 7 and end 8, and between the shoulder 22 and a surface 23 fixed to the member 1. The outlet end of the tube 9 leads to both the piston 5 and an exhaust channel 17 via a restriction 16; the chamber 21 also opens to the channel 17 via another restriction 26. Movement of the end 8 away from the head 7 increases the pressure inside the tube 9 and hence that acting on the piston 5 ; the resulting motion of the member 1 increases the distance between the shoulder 22 and surface 23 whereby the fluid pressure in chamber 21 increases and lifts the tube 9 towards the end 8 to re-establish equilibrium conditions. The tube 9 is guided by a bearing 28 and channels 31, 32 are provided to exhaust any leakage fluid. In another form, the pressure fluid controlled by the tube 9 actuates a slide valve forming a bleed-off for the pressure supply to the piston, which supply may be the same as or different from that connected to the tube.

Alarms; margin stops; sheet-guiding arangements.-A device for indicating when the bottom edge of a sheet has reached a predetermined point is supported on the paper-apron by means of a clamp and comprises a pivoted support for a strip carrying a bell which rings when the sheet releases the strip. The device shown in Figs. 1 and 2 is supported on the paper-apron 1 by means of a clip 4, having jaws 5, 6 provided with fingerpieces 7, 8. A bell 28 is suspended from a metal strip 26 passing through a rocking flanged guide 23 having a lug 25<1> which enters a slot in the finger-piece 7. The strip has numbered projections 32 which are set with reference to pointers 25 on the guide 7 to adjust the end of the strip with respect to the sheet 31. The bell normally rests on a pad 30 arranged between wings on the strip, and is thereby prevented from ringing when the carriage moves. The sheet is diverted from the platen 3 by means of spring-fingers 20 each formed with a spring-finger 19 for holding the sheet in contact with the paper-apron and strip. The fingers are formed with lugs 21 engaging a notched tube 11 provided with rods 12, 14 having bent ends entering the coiled ends 16 of rods 17 formed with hooks 18 engaging notches in the jaw 6. The rod 14 can be drawn out of the tube to fit the device to paper-aprons of different sizes. When the bottom edge of the sheet passes over the end of the strip, the strip rocks upwards, and the bell rings.

Title: Improvements in or relating to motion picture projectors
IPC: G03B21/43
Filed: 1937-12-14
Abstract: 497,114. Kinematograph projectors. KODAK, Ltd. Dec. 14, 1937, No. 34628. Convention date, Dec. 17, 1936. [Class 97 (i)] In a projector in which the takeup reel is normally both driven and supported by frictional means, means is provided for displacing the reel, during rewinding, to relieve the film tension produced by the frictional means. As shown, the take-up reel 17 is mounted on a spindle 25 carrying a pulley 38 driven by a belt 37 passing over pulleys 40, 41 from a driven pulley 35. The spindle 25 is carried in a sleeve 31 on an arm 27 free on a pivot 28, and the pulley 38, reel, and arm, are normally supported by the belt. A switch 150 controls a motor 60 which drives the payout reel during rewinding, and its arm 151 is operated by lugs 153, 154 on a finger lever 152. A pin 158 on the lever 152 engages a slot 157 at. one end of a link 155 pivoted on the arm 27. For rewinding, the lever 152 is depressed, thus causing the lug 154 to move the arm 151 and close the switch, and causing the pin 158 to engage the upper end of the slot 157. Further depression of the lever 152, by continued manual pressure, operates through the link 155 to raise the arm 27 and free the belt 37 from the pulley 38; when sufficient film has been wound from the reel 17 to free the film from excessive tension, the pressure on the arm may be released, thus allowing it to resume the previous position. Upward movement of the reel 17, due to drag of the film during rewinding, is restricted by engagement of the pin 158 with the lower end of the slots 157. The effective length of the link 155 may be changed by adjustment of the pivotal connection to the arm 27. The arm 27 &c. may be housed in a recess 26 in the projector casing, during transport, by first turning the sleeve 21 about a pivot pin 32 on the end of the arm 27, and then turning the arm about the pivot 28, a slot 161 being provided in the link 155, extending from the slot 157, to ride over the pin 158 during the movement. The invention is shown applied to a projector of known construction, wherein the film, during projection, passes from a reel 13, and over a roller 19, to a take-up reel 17 in a plane at right-angles to that of the reel 13. The reel 13 is carried by a spindle extending from a hollow support 12, and rotatable so that the plane of the reel 13 is parallel to that of the reel 17 during rewinding; when the spindle is so rotated, a clutch connects it to a shaft 64, within the support 12, which is driven by the re-winding motor 60 through a belt 69, pulley 61, and bevel gears 62, 66. The support 12 may be turned about its bottom end, when not in use, so that the spindle thereon may be housed in a recess 16. The pulley 35 is driven, during projection, by gearing from a shaft 100, connected by a two-step cone pulley 101 and a belt 106 to a two-step cone pulley 103 on the shaft of the driving motor 105.. Belt-shifting means is described. U.S.A. Specification 2,099,299 is referred to.
