Title: Improvements relating to heat exchangers
IPC: F22D1/02
Filed: 1957-06-21
Abstract: 836,247. Tubular heat exchangers. VISER, J. M. June 21, 1957. No. 19536/57. Class 64(3) [Also in Group XXVIII] A heat exchanger comprises at least one tube within which is arranged a plurality of twisted strips disposed around a core member. The tube may be circumferentially corrugated and the twisted strips may be wound helically around a hollow core plugged at both ends (Fig. 1, not shown). Fig. 6 shows one form in which in a heat exchanger tube 23, a plurality of twisted strips 24, 25 are arranged around a solid core 24. In a further form shown in Fig. 3 twisted strips 16 in a heat exchanger tube are disposed around a core 13 itself comprising a tube carrying one of the heat exchanging fluids and containing twisted strips 14, 15 disposed in the manner shown. The other heat exchanging fluid flows through the annular space between tubes 12 and 13. Adjacent strips may be twisted in opposite directions. The strips may be welded at their ends to the core and, if liquids which tend to deposit solid matter are used in the heat exchange, the core and twisted strips may be rotatable as a unit to keep the tube walls clean. The invention may be incorporated in U-tubes through which oil is passed for heating by steam flowing over the tubes (Fig. 4, not shown).
Patent GB-767224-A (GB)
Title: Production of emetine
Inventor: GLYNN HARRY EPHRAIM
IPC: C07D455/08
Filed: 1954-07-03
Abstract: Emetine is obtained by aqueous mineral acid extraction of ipecac root which is not ground and is in a substantially whole condition.  The acid is preferably used in 1-10 per cent concentration, e.g. 4-5 per cent sulphuric acid.  The acid extract is made alkaline, e.g. with ammonia, and extracted with a water-immiscible organic solvent such as trichlorethylene or methyl isobutyl ketone.  Any emulsion formed may be broken by filtration through diatomaceous earth or by centrifugation. Emulsification may also be minimised by precipitating the proteins (e.g. by Irish moss extract) before making the extract alkaline. The solvent layer is separated and re-extracted into aqueous acid. The aqueous phase is made alkaline with ammonia, extracted with solvent such as ether and the extract treated with sodium hydroxide.  The ether phase is extracted into aqueous acid and sodium bromide added when emetine hydrobromide crystallizes out. The aqueous phase contains the phenolic alkaloids such as cephaeline which may be separated and converted into emetine.  An example is given of the process.

Title: Improvements in maximum demand indicators for gas and like meters
IPC: G01F15/07
Filed: 1928-07-06
Abstract: 316,412. Shewring, H., Glover, W. T., and Meters, Ltd. July 6, 1928. Periodic-counter speed indicators.-In meters with maximum demand indicators the member which displaces the indicating pointer is returned at predetermined intervals to its initial position by interrupting the drive thereto from the operating part of meter by means of a mechanism operated by a spring which is maintained wound from the operating meter part and is controlled by the usual clockwork mechanism, means being provided to prevent overwinding of the spring. In the form shown, Figs. 1 and 4, the operating shaft a of the meter has an eccentric b oscillating a lever c carrying a pawl d driving a ratchet wheel e to wind up through gears f, g a spring within a barrel h, overwinding being prevented by a cam i and spring controlled bell-crank lever j cooperating with the tail of the pawl d. The shaft a through worm gearing n, o drives a wheel p to which is pivoted a pawl q adapted to drive a ratchet wheel u having a projection v co-operating with a pin w upon a member x carrying the indicating pointer y. During the time the pawl q drives the wheel u a spring z, Figs. 2 and 3, is wound up and upon release of the pawl q by means of an arm r on its spindle, due to the longitudinal movement of a conical-shaped member t, the spring z returns the wheel u to initial position. The longitudinal or axial movement of the member t is controlled by the clockwork mechanism 80 and the spring barrel h. The clockwork drives a wheel 8 and the barrel spring a shaft carrying a notched disc 2, Fig. 4, and a star wheel 5, Fig. 5. The wheel 8 has twentyfour teeth and rotates once in twenty-four hours so that once every hour a lever 6 is rocked to release the arm or catch 7 from a notch in the wheel 2 to permit the star wheel 5 to rotate. The wheel engages the end of an arm 10 and imparts a movement thereto and to an arm 11 connected by a link 12 to an arm 13, Fig. 1, the arm 13 being pivoted at 14 and connected to an arm 15 pivotally attached to the member t. An additional maximum demand indicator 16 may be provided operating at longer intervals of time. This indicator is secured to a spindle 34 and is operated by mechanism similar to that described above, the wheel 20 corresponding to the wheel p being driven through a reduction-gearing 21 from the wheel p and the conical member 23 being operated by an arm 22 through an arm 24 adapted to cooperate with the link 12 by the engagement of a roller 29 on the arm 24 with a recess' 30 in the link 12. when the arm is allowed to fall by withdrawing the supporting roller 25 of an arm 26. As shown this is effected once in twenty-four hours when the notch 4 in the clock driven disc 3 is engaged by a pin 28 on the lever 26.

Title: Sheet or film packaging material
IPC: B65B57/04
Filed: 1962-05-24
Abstract: 951,362. Seaming non-metallic sheet material. DOW CHEMICAL CO. May 24, 1962 [June 5, 1961], No. 19982/62. Heading B5K. [Also in Division B8] Relates to packaging material having coloured or opaque areas adapted to actuate a photoelectric sensing unit in an automatic packaging machine for controlling operations thereof. According to the invention two or more lengths of packaging material are joined end-to-end to form a long continuous roll, the join being effected by pressure-sensitive adhesive tape having a plurality of alternating light transmitting or transparent portions and opaque portions which are preferably of a brilliant colour. The tape is positioned across the adjacent or overlapping ends of the packaging material so that the transparent portions of the tape are in general longitudinal alignment with the opaque areas of the material and no part of any opaque portion of the tape is in longitudinal alignment with any part of the opaque areas of the material. Thus the tape does not interfere with the operation of the sensing unit and the coloured portions of the tape enable a package formed with the spliced portion of the material to be readily identified for removal.

Abstract: Mixed textile materials, e.g. fabrics or yarns, consisting of animal and vegetable, animal and regenerated cellulose or animal, vegetable and regenerated cellulose fibres, are dyed in solid shades fast to light and washing by padding with an aqueous solution containing a salt of a sulphuric acid ester of a leuco vat dyestuff, a swelling agent, an acid generating agent, a solubilizing agent and a wetting agent, drying, steaming, and developing the colour in an oxidizing bath.  The preferred swelling agent is a sulphocyanide, e.g. ammonium sulphocyanide which may function also as an acid generating agent. The preferred acid generating agent is a dialkyl tartrate, e.g. diethyl, dibutyl or diamyl tartrate.  Specified solubilizing agents are diethylene glycol and glycerol and specified wetting agents are alkyl-, e.g. isopropyl-, naphthalenesulphonic acids and the sulphonated mineral oil-alcohol condensation products described in Specification 274,611, [Class 15 (ii)].

The said pressure causes a flow of metal through an opening 14 into the cavity 8 which fills any pinholes and shatters and dislocates the basaltic structure which tends to form thus resulting in the production of blanks having a fine, dense axially symmetrical structure with a reduced region (25) of coarse, basaltic structure which does not at any point reach the periphery of the blank. The pressure may be generated by compressed air introduced through a line 17 to the interior of a cap 15 which, in use, sits on the covers 9 and 10. The base of the mould is cooled by a coolant, e.g. water, air or a water-air emulsion, supplied through a conduit 3 and leaving through a conduit 4. The covers 9 and 10 may be moved towards and away from one another by means of jacks 12 and may be heated by a gas burner 11 or electrical heating means. The blanks may be used to form tubes, casings, cans, aerosol cylinders and bottles or cartridges for compressed or liquefied gases.
