Abstract: 309,252. Rose, W. V., and Keeble, C. A. Jan. 28, 1928. Delivery of articles stored in piles.-The bottom article of a pile stored in a magazine 7 is delivered after the insertion of two coins by a drawer 8, Figs. 2, 3, having a portion 11 to move the article and cause it to fall through a delivery shoot. The drawer is pulled out by a handle 9 and returned by springs, full-stroke mechanism being provided. The drawer is normally locked by the hook 30 of a plate 28 engaging a bar 31, the plate being pivoted at 29 and passed by a spring towards the drawer. Coin action, mechanical-connection and multiple-coin.-The coins inserted through a shoot 13 are diverted by the end 19 of a lever 17 to branch shoots 15, 16. The lever 17 is pivoted at 18 and carries two arms 20, 21 forming a rocking beam with a backwardly and downwardly sloping surface. The coins drop from the shoots 15, 16, one on each arm 20, 21, and are positioned by fixed guides 25, 26. When the drawer is pulled out the coins are moved up the inclined surface of the beam and engage a rod 32 carried by the locking plate 28, thereby raising the hook 30 out of engagement with the bar 31 on the drawer. If only one coin is inserted, the beam is tilted so that the hook 30 engages the bar 31 before the coin makes contact with the rod 32.

Title: Improvements in or relating to heat exchange apparatus
IPC: F28F9/26
Filed: 1951-02-05
Abstract: 707,888. Tubular heat-exchange elements; refrigerating systems; heating and cooling buildings. HEAT-X-CHANGER CO., Inc. Feb. 5, 1951 [July 27, 1950], No. 2846/51. Classes 29, 64(2) and 64(3) [Also in Group XXII] A metallic fin assembly in the annular fluid passage 32 between a pair of coaxial heat-exchange tubes 26, 28 comprises straight sheet-metal fins 108 extending longitudinally of the passage and connected to one another by trough-like parts which are held tightly against the tube surfaces, the distance between the tubes being such that the fin assembly is compressed and the trough-like parts are slightly distorted. The fin assembly is a corrugated metal sheet. The trough-like parts in contact with the inner tube are of smaller diameter than those in contact with the outer tube. The condenser 21, Fig. 4, of a refrigerating system, Fig. 2, comprises a number of these pairs of tubes connected to headers 22, 24 which are composed of interfitting channels 40, 42, 44 and are divided internally by arched walls 62, 80, 86, 88. The evaporator, 19 is of the same construction, except that the outer tubes have square external sheet metal fins 117. The refrigerant flows from the compressor 2 through the annular passages in the condenser and evaporator, through a condensate receiver 8, and an expansion valve 12. The evaporator is de-frosted by passing a hot liquid through the inner tubes. Cooling water flows through the inner tubes of the condenser 21 at a rate controlled by a valve 29 actuated by the pressure of the refrigerant vapour flowing to the condenser, so as to keep that pressure within a desired range. In another refrigerating system, Fig. 1, compressed refrigerant flows through a primary condenser 6 composed of simple finned tubes to a header 138 at one end of the annular passages in a secondary condenser 7 which is a modification of the condenser shown in Fig. 4. Uncondensed refrigerant passes into the annular passages, and when condensed returns to the header 138. The condensate flows from the header 138 through the receiver 8 to the evaporator 14, and then through the inner tubes 28 of the condenser 7 back through the pipe 16 to the compressor. All the inner tubes of this condenser may be arranged in parallel. Hot refrigerant from the compressor is passed directly to the evaporator 14, when it needs defrosting, through a valve 17 and pipe 18. The throttle 19<SP>1</SP> is closed by the rise in pressure, and the refrigerant is condensed in evaporator 14 and re-evaporates in the inner tubes of the condenser 28 before returning to the compressor. A system similar to that shown in Fig. 2 is used for heating and cooling a room, the evaporator 19 acting as a radiator. During hot weather the refrigerant is circulated, and during cold weather a hot fluid, e.g. steam, is circulated through the inner tubes of the radiator. In this system, the outer tubes of the condenser have transverse external fins. Specifications 639,313 and 676,924 are referred to.

Patent GB-866421-A (GB)
Title: Distillation apparatus
IPC: B01D3/30
Filed: 1959-01-27
Abstract: Fractional distillation apparatus for use at subatmospheric pressure includes a reboiler, a condenser, a vacuum system and at least one distillation column, means being provided for compressing the vapour of the material being fractionated to a pressure not higher than the pressure in the reboiler during its <PICT:0866421/III/1> <PICT:0866421/III/2> passage through the distillation column or columns, or during its passage from one distillation column to the next when a plurality of columns are used in series.  In Fig. 1 apparatus comprising two columns T1 and T2 each containing 60 plates can be used for the separation of a mixture of para- and orthonitrochlorobenzene.  A vapour compressor B is included in the conduit from the top of T1 to the bottom of T2. Liquid mixture is fed by a pipe F to the bottom of T2 (or at any position in either column depending upon the composition of the mixture) and distillate is removed from a condenser C through a pipe D, the reflux from the bottom of T2 being pumped by pump P to the top of T1 while residue is removed from the reboiler R through a pipe W.  By regulating the vacuum pump VP and compressor B the pressures in the columns can be controlled to avoid decomposition of the mixture being fractionated. Whatever the number of columns n only one reboiler, condenser and vacuum system is employed, while n-1 compressors are necessary, each column and the next having a compressor between them.  In Fig. 2 the column T is of the rotary disc type in which discs a mounted upon a rotatable shaft s revolve between annular discs c fixed to the column wall.  Vanes b attached to the discs a compress the vapour as it rises up through the column, thereby rendering unnecessary the use of a separate compressor whether one column is used or two, as in Fig. 1.

Patent GB-968873-A (GB)
Title: Process for dewaxing hydrocarbon oils
IPC: C10G73/24
Filed: 1961-01-27
Abstract: Hydrocarbon oils are dewaxed by forming urea adducts of paraffins with a dispersion of urea prepared by stirring urea or a saturated aqueous solution thereof with an organic dispersion medium at or below the "formation" temperature (at which on cooling a mixture of the organic medium and the saturated urea solution from above its saturation temperature sedimentation of urea ceases on further cooling) and, when a saturated solution of urea is used, also below the saturation temperature of the solution.  It is preferred to use an aqueous urea solution having a saturation temperature of 55-105 DEG  C., preferably 55-80 DEG  C., and to form the adduct below the demixing temperature, i.e. the temperature at which the dispersion on being heated separates into aqueous and an organic solvent phases. As dispersion media there may be used halogenated hydrocarbons, ketones, aliphatic hydrocarbons which do not form adducts with urea, esters, ethers or aliphatic amines, methylene chloride, acetone and octane being preferred.  The adducts formed between oils and such urea dispersions are easily separated and are decomposed, e.g. with steam.  The urea solution thereby obtained is concentrated, mixed with organic solvent and cooled below the "formation" temperature by allowing a part of the solvent to evaporate.
