Patent GB-653591-A (GB)
Title: Improvements in or relating to cyclic amino alcohols
Filed: 1948-10-22
Abstract: A 1-(alkyl, aryl or aralkyl)-3-hydroxy-5-alkoxy piperidine is produced by reacting together at substantially 100 DEG  C. a 1 : 2-epoxy-4-alkoxy-5- halo pentane and a primary alkyl, aryl or aralkylamine.  The product may be dealkylated by treatment with hydrobromic acid to form a 1-(alkyl, aryl or aralkyl)-3 : 5-dihydroxy piperidine.  When the amine employed is volatile the reaction may be effected in a sealed vessel.  In examples: (1) 1 : 2-epoxy-4-methoxy-5-bromo-pentane is heated in a sealed tube at 100 DEG  C. with anhydrous methyl amine.  After extraction with the minimum of water, the solution is saturated with potash and the separated oil extracted with benzene.  On distilling the dried solution, 1 - methyl - 3 - hydroxy-5-methoxy piperidine is obtained. The latter is converted to 1-methyl-3 : 5-dihydroxy piperidine by adding it to a solution of anhydrous hydrobromic acid in glacial acetic acid and heating to 100 DEG  C. until there is no more evolution of methyl bromide.  The temperature is then kept at 100 DEG to 110 DEG  C. for one hour and the mixture dissolved in absolute alcohol and treated with hydrated barium hydroxide.  The insoluble matter is filtered off and the solution distilled to yield the dihydroxy compound; (2) as in (1) but using ethylamine instead of methylamine, the product being 1-ethyl-3-hydroxy-5-methoxy-piperidine which is converted to 1-ethyl-3 : 5-dihydroxy piperidine by treatment with hydrobromic acid; (3) 1-phenyl-3-hydroxy-5-methoxy piperidine is obtained by heating the same starting material as in (1) with aniline.  The halogen atom in the 1 : 2-epoxy-4-alkoxy-5-halopentane is preferably chlorine, bromine or iodine.  1 : 2 - Epoxy - 4 - methoxy - 5 - brom - pentane is obtained by the action of a solution of perbenzoic acid in chloroform at -5 DEG  C. on 1-bromo-2-methoxy-4-pentene which is itself obtained by the action of N,N-dibromo-p-toluene sulphonamide on 1 : 4-pentadiene in methyl alcohol.  The Specification as open to inspection under Sect. 91 is not restricted to reaction at a specified temperature and refers to the use of any dealkylating agent in the production of the 1-(alkyl, aryl, or aralkyl)-3,5 dihydroxy piperidine.  This subject-matter does not appear in the Specification as accepted.

Title: Improvements in and relating to driving gearing for planing or other machine tools
IPC: B23D7/00
Filed: 1938-09-22
Abstract: 509,552. Grinding-machines. BRITISH THOMSON-HOUSTON CO., Ltd. Sept. 22, 1938, No. 27656. Convention date, Sept. 24, 1937. [Class 60] [Also in Groups XXII and XL] A machine tool such as a milling, planing, slotting or grinding machine has the working and traversing speeds and the reversal controlled by scanning a pattern of the same shape as the work-piece by a scanning device whose position on the pattern always corresponds with the position of the tool on the work. In the application to a planing machine, the table 2 carrying the work is reciprocated by a motor 10, while the tool 4 is fed horizontally or vertically by motors 9, 8 respectively. Control for planing a piece of the shape shown by the continuous vertical lines in Fig. 4 is effected by means of a photo-electric cell 14 operating in conjunction with a templet consisting of a scale drawing of the work having different translucence in different parts. For example the surface corresponding to machining areas may be shaded grey, quick traverse areas may be white and the margins where reversal of the stroke is to be effected may be black. The cell is moved so that its position always corresponds with the position of the tool on the work. For this purpose a block carrying the cell may be moved by screws 17, 18 driven from splined shafts 21, 22 respectively, these shafts being driven by motors 23, 24 coupled by the Selsyn system with the table motor 10 and the feed motor 9. Where the tool passes over gaps in the work-piece as shown by dotted lines in Fig. 4, the high-table speed is effective. Suitable allowances may be made on the templet to ensure that the correct cutting speed becomes effective before the tool engages the work. Alternatively, the scale of the templet may be enlarged or a modified transmission ratio of say 1 : 1.1 may be employed between the scanning-cell drive and the machine drive. In a modification, the scanning may be effected mechanically. For instance, the templet may have sections cut to different depths and be scanned by a ball device 28, Fig. 6, actuating contacts 31 which control the speed and direction of the driving motor. Alternatively, electrical measuring heads may effect the control. The transmission of the scanning movement may be through toothed gearing or. by pantographs, the motors 23, 24 being dispensed with.

Title: Improvements in or relating to methods and apparatus for drying webs that are subject to shrinkage during the drying thereof
IPC: F26B13/22
Filed: 1936-10-13
Abstract: 471,640. Drying films. BRITISH CELLOPHANE, Ltd. Oct. 13, 1936, No. 27818. Convention date, Oct. 23, 1935. [Class 34 (i)] The invention relates to a method of and apparatus for drying a non-fibrous self-supporting transparent web or film subject to shrinkage in drying, including regenerated cellulose films and also non-cellulosic sheets of a similar nature. The web is passed into contact with one or more drying rolls subject to external heat treatment for maintaining the peripheral roll surface in a substantially dry state. Preferably the web is preliminarily dried to prevent sticking to the rolls. Materials may be applied to the sheets to make them waterproof and prevent transmission of ultra-violet light and to anchor subsequent coatings to the film. Fig. 1 shows apparatus in which there is preliminary heating of the film. A comparatively wide regenerated cellulose film 10 undried is led through a liquid bath 11 to squeeze rolls 13 and thence through a drying chamber of the type described in Specification 471,641. The web is unsupported between rolls 13 and 16. A plurality of headers 18 extend preferably obliquely towards the web and supply hot air or gas flames for drying the film. When burners are used they are so spaced that there is space for an ample supply of secondary air to reach the flames and allow combustion gas to escape. The burners may be adjustable. A number of openings 22 are allowed for hot gas to escape, assisted by a fan. The web passes from the roll 16 to a series of drying rolls 40. The first set of rolls are preferably confined in a chamber 46, in which hot gas jets are provided and suction means 44 for withdrawing products of combustion by conduits 49, 50. The jets 42 are directed against the peripheral parts of the rolls out of contact with the web 10 while the suction means 44 are arranged adjacent the webs. This prevents adhesion between the web and the rolls. Additional drying rods 40 unenclosed are used to remove most of the remaining moisture content leaving sufficient to be desirable. The web is wound on a shaft 51. The speed of the rolls may be regulated to allow for shrinkage. Requisite heat may be by gas or electricity or by heated air or other gas over steam coils or by combustion. The heat supplied must be by convection and/or radiation and not conduction. The wet web may contain more than 300 per cent of water and the dried one less than 10 per cent. In a modified form of apparatus, Fig. 2, the preliminary drying chamber is omitted.

The front end 18 of the shaft is made square and fits a corresponding square opening in a cover 17, the periphery of which is formed with teeth 21 adapted to engage teeth 13 in a drum 10 rotatably mounted in the casing 6. The engagement of the teeth is brought about by a spring 22, the cam 1 may then be rotated by the cover 17, a yielding spring catch 24 on the casing co-operating with slots 11 on the drum and a pin 25 with a groove 26, to hold the parts in the set position and to limit the rotation respectively. The range is indicated by a scale on the drum 10 visible through a window 27 in the casing. For the purpose of the invention, two sets of logarithmic scales are marked on the cover 17 and on a retaining ring 23 screwed into the drum 10. As shown in Fig. 5, these scales comprise two range scales A, A<1> co-operating with each other and a scale B of barometric pressures co-operating with a scale C of temperatures both correlated to air density on the basis of the Mariotte-Gay-Lussac law ; so that the setting of the scale B on the scale C determines the ratio of densities, and the relation between the scales A, A<1> then gives the range multiplied by that ratio.

Title: Improved low friction bearings for linear motion
IPC: F16C29/04
Filed: 1958-09-01
Abstract: 852,439. Bearings. RANSOME & MARLES BEARING CO. Ltd. Sept. 1, 1958 [March 3, 1958], No. 27965/58. Class 12 (1). Friction in a rectilinear-motion bearing between a member 8 and a shaft 2, along which the member 8 is adapted to move, is substantially reduced by causing rapid reciprocation of the shaft 2 through a small amplitude along the shaft axis. The reciprocation is effected by a cam 5 driven by a motor 6 and a spring 7. In a modification, shown in Fig. 2, a bearing 11 of the recirculating ball type is mounted within a larger linear ball-bearing 13 and is attached to a core 15 located in a coil 16 which, together with a spring 17, causes reciprocation of the bearing 11 relative to a shaft 12 which serves as the mass of an inertial sensing device. The shaft 12 is located axially by a spring 18 and carries a potentiometer coil 19. In a further modification, a ball-bearing 21, Fig. 4, carries a mass 23 and is adapted to move along a rail 22 which is reciprocated at a relatively high frequency. U.S.A. Specification 2,628,135 is referred to.
