To this period also belongs Mallons Patent (182377, 1876) forthe use of steam applied through a hollow trash bar, a device also to be foundin connection with Le Blancs four-roller mill (patent 5494 of 1883). Compound imbibition is perhaps first distinctly described in 1884 inconnection with the eight-roller mill of Brissoneau and La Haye. It alsoforms the subject of a patent ( 787101, 1904) granted to Lorenz, butby this time the process was no longer ^^ Fig. 147 In employing imbibition schemes, difference of opinion exists as towhether hot or cold water should be used. The natural answer would bethat hot water is the more effective agent, but very detailed experimentsmade by Von Czernicky in Java show that no difference is to be found ontests, and this has been the experience of the writer. At thepresent time the standard method of operation comprises the useof a perforated pipe of a saw-cut trough, whence the diluent is delivered tothe blanket of bagasse. This process is the same as that patented byRobinson eighty years ago. Some other more detailed schemes which do notseem to have come into extended use are mentioned below. Injectors.—As a means of obtaining a better distribution of the diluent,injectors arranged in a row parallel to the rollers may be used. Such ascheme is indicated in Fig. 1
