Title: Improvements in or relating to methods of cooling and to the cooling of fluid streams
IPC: F25B9/00
Filed: 1963-09-27
Abstract: 1,000,590. Refrigerating; liquefaction of gases. ALLIED CHEMICAL CORPORATION. Sept. 27, 1963 [Oct. 1, 1962], No. 38115/63. Headings F4H and F4P. A multi-stage refrigeration system comprises a set of expansion turbines connected in parallel between refrigerant supply and return lines to define zones of successively lower temperature, the arrangement being such that the portion of the refrigerant stream passing through any one expansion turbine passes through the higher temperature zones of the system before and after passing through that expansion turbine, the pressure ratio across each turbine being in the range 1À5 to 3À5. As shown, hydrogen is compressed in compressors 77, 75, 79 and 81 and is then passed through a coil 93 in the evaporator 10 of an absorption-type refrigeration system whence it passes to a coil 99. Part of the gas in coil 99 is tapped off at 103, expanded in a turbine 101 and returned via a coil 105 to compressors 75-81 while the remainder of the gas passes to a coil 107. The refrigerant then passes through a first series of coils to a turbine 125 and returns to the compressors through coils 127, 130, 133, 113 and 105, expansion turbines 109, 117, and 122 being connected to withdraw a portion of the gas from each of the first series of coils and supply it to the appropriate one of coils 130, 133 and 113. The multi-stage refrigeration system is used to cool a series of coils 144, 148, 150, 153 and 155 through which hydrogen is passed to a Joule-Thomson valve 160, the hydrogen liquefying at the valve to form a liquid bath 166 in a tank 30. Vapour from above the bath is returned through coils 169-177 to a series of compressors 184, 190, 196 having inter-coolers 188, 193, 199. The above systems are used to liquefy hydrogen which is supplied through a line 202, pre-cooled in a coil 210 in the absorption system evaporator 10, and then passed through a series of coils 221-229 cooled by the multi-stage system. Finally the hydrogen is liquefied in a coil 230 immersed in bath 166 and is passed to a storage tank 239. Activated carbon filters or molecular sieves may be used to remove liquefied nitrogen and methane from the hydrogen stream. The compressors 75-81 are driven by two combustion engines 69, 72, the exhaust gases of which are used to heat the generator 48 of the absorption system.

Abstract: 1,066,948. Packaging X-ray film. EASTMAN KODAK CO. Sept. 27, 1963 [Sept. 28, 1962], No. 38123/63. Heading B8C. [Also in Division H5] A pressure-sensitive strip of X-ray film 11 between sealer packaging webs 12, 14 is coiled on to a reel 34, the wrapper webs being fed differentially so that the wrapper web 14 forming the inner surface of each convolution of the package is shorter than the wrapper web 12 forming the outer surfaces, spurious straightline images due to wrapper creases being thereby avoided. The film supply reel 10 containing 1000 feet of film strip has a magnetic brake 18 and the supply reels 13, 15 for the outer and inner wrapper webs of kraft paper with heat sealable mating surfaces are braked by weighted canvas strips 16, 17. The paper webs and film are aligned at 22, 23 and 25 and the outer wrapper web 12 is printed for identification at 26. The lower wrapper web 14 engages a substantial portion of a rubber covered drive roller 30 driven by a synchronous motor 28 through clutch 29. The motor 28 also drives a pair of heated edge sealers 31 and, through an adjustable torque slipping clutch 32, the takeup reel 34. The drive is controlled to produce a differential tension between the outer and inner wrapper webs, the greater tension being in the inner web to prevent creases. Air is purged from the package by wringer rollers 42. In a modification, the wrapper webs are not differentially tensioned, the rollers 38, 30 being idlers and the composite web being presented to the edge sealers at an angle and the wringer rollers skewed to effect a pre-bending during edge sealing and consequent differential travel of the outer and inner wrapper webs. An arcuate guide forward of the edge sealers maintains the curvature and prevents the differential travel being lost through slippage of the still tacky edge seals.

Title: Improvements relating to fancy yarn frames
IPC: D01H5/36
Filed: 1956-12-27
Abstract: 837,314. Fancy yarn doubling frames. BERLINER MASCHINENBAU AKTIENGESELLSCHAF VORM. L. SCHWARTZKOPFF. Dec. 27, 1956 [June 12, 1956], No. 39273/56. Class 120(2) [Also in Groups XXXV and XXXVII] In a fancy doubling frame, each thread delivery roller is braked or driven in response to a programme repeater unit, the drive being made via one of at least two transmissions in response to magnetic couplings controlled by at least one other programme repeater unit. As shown, Fig. 1, each of two delivery rollers 1, 2 is driven from a shaft 8, either via a chain and sprocket drive 7, 6, giving a 1 : 1 gear ratio or via gears 13, 12, 4 providing a selected gear ratio. Drive at one or other speed is provided when the armature 10 of a double magnetic clutch is engaged with one or other of two clutch members 9, 11. A magnetic brake 14, 15 arrests roller 1 when neither of clutch members 9, 11 is engaged. Electrical programme repeater units 16, 17 and 18, 19 for operating the magnetic clutch and brake are mounted on a shaft 20 driven, through variable-speed gearing, from shaft 8. Each programme repeater unit may consist of a switch operated by a cam disc, the shape of which can be adjusted to provide a desired switching programme. Variation of the speed of a roller will produce an elongated fancy effect, while disengaging and braking of the roller will produce a spot effect. In an alternative programme repeater unit, Fig. 5, a conductor 40 is connected via a slip ring 33 to a rotary brush 30 passing over a ring of contacts 25, selected ones of which are connected via a ring 27 with a second conductor 41, by means of split pins fitting in holes in the ring 27 and contacts 25. Rotation of brush 30 by a shaft 35 thus effects a programme of switching between conductors 40 and 41; this programme can be changed without stopping the machine, by changing the positions of pins 29. Shaft 35 is driven from a shaft 39 through a wheel 37 and friction disc 36; wheel 37 may be shifted to vary the speed ratio of the drive to shaft 35, or it may be moved automatically to modulate the repeater unit. In another, similar, unit, instead of using pins 29 located on the unit, connections are provided to selector switches on a switchboard located outside the machine. In a further construction, Fig. 7, the whole unit is located outside the machine. A sliding contact 61 in the unit is rotated by a ratchet wheel driven step-by-step by the armature 74 of an electromagnet 71 supplied with A.C. pulses produced by a rotor 63 mounted on a shaft 62 driven similarly to shaft 35, Fig. 5. Contact 61 is connected to one conductor 76 and rides over a ring of contacts 57 selectively connected by switches 58 to the second conductor 77. The control units of Figs. 5 and 7 control the magnetic clutches via relays.
