Patent GB-359058-A (GB)
Title: Improvements in or relating to absorption machines for producing cold or heat
IPC: F25B15/10
Filed: 1930-07-22
Abstract: 359,058. Refrigerating. SIEMENSSCHUCKERTWERKE AKT. - GES., Siemensstadt, Berlin. July 22, 1930, No. 22103. Convention date, July 25, 1929. [Class 29.] Absorption systems.-In continuous-cycle systems employing a pressure-equalizing inert gas, the refrigerant evolved from solution or evaporated circulates by diffusion through the inert gas, which has no movement of circulation. In the system shown in Fig. 1, ammonia is generated from solution in a heated generator 2, rises with the liquid to a separator 14, and passes to a condenser 8, and then as condensate to the evaporator 6. The solution flows from the separator through a pipe 4 and a heat interchanger 10 to the absorber 5, which is located above the evaporator and communicates therewith through a central conduit. The evaporator is traversed by brine &c. pipes 13 and is heat insulated, while the absorber casing is of conducting material to dissipate the heat to the surroundings. The evaporator and absorber contain an inert gas not considerably heavier than the refrigerant, such as methane, hydrogen, helium or a mixture. Since the warmer zone of the absorber is above the colder zone of the evaporator there is no tendency for the inert gas to move by change of density. In the arrangement shown in Fig. 2, the solution from the separator 27 above the main generator 21 flows by a pipe 32 to a secondary generator 22 located in a drum 29 filled with inert gas. The liquor flows from this secondary generator by a pipe 33 and interchanger 34 to an absorber 23 located above the evaporator 26 in another drum 37 also filled with inert gas, and from this absorber the liquor flows by pipe 38 to a secondary absorber 24 at the bottom of the first drum. The gas spaces of the drums communicate by a wide bore pipe 45, 40 through which liquor from the absorber 24 and excess refrigerant from the evaporator can pass back to the main generator. The generator 21 may be heated by a low temperature medium such as exhaust steam. The vapour from the secondary generator diffuses into the inert gas in drum 29 and is absorbed in the liquor below, while the vapour evaporated in the lower part of the other drum diffuses upwards and is reabsorbed in the absorber 23. The inert gas may be a mixture of helium and neon having approximately the same density as the refrigerant. The ammonia from the separator 27 enters below the liquid level in the condenser 25. The generator and absorber vessels in the drum 29 may have vertical baffles to bring fresh parts of the solution to the top, and the drum may be fitted with transverse vertical partitions through the generator and absorber vessels to prevent endwise movement of the inert gas. The liquids flow from end to end of the drum in counterflow. The warm generator may be located below the absorber in a vessel shaped as an inverted U-conduit, the inert gas being stagnant above the absorber in the shorter limb.

As shown, the tins are delivered from the oven to the endless, e.g. wire mesh, conveyer 12 where they are guided by rails 52 on a frame interchangeable according to the size of the tin in use. The tins are retained on the conveyer round roller 15, e.g. by magnetic or electromagnetic means within the drum, the pies being held in the tins by a guard plate 16 or an endless band. The tins are received inverted on conveyer 17 adjacent whose upper run there are fixed and adjustable guide rails. As the conveyers diverge an adjustably mounted permanent or electromagnet 20 above the lower lap of conveyer 12 separates the tins from the pies and ultimately deposits them on conveyer 70. The pies continue inverted on conveyer 17 and are carried round drum 19, held by a guard 23, and then deposited right way up on an endless delivery conveyer 24 with adjacent fixed and adjustable guide rails. The conveyers are all driven through chain-and-sprocket drives by a motor 27. The shaft of one of the two rollers carrying each of the four conveyers is adjustable and quickly removable, shaft 38 for example being journalled in bearings 39, 40 slidable between fixed guides.
