Filed: 1975-05-01
Abstract: 1512366 Thermal regenerators G APPLEGATE 1 May 1975 [8 Feb 1974] 05781/74 Heading F4K An arrangement for heat exchange between a hot gas stream and a cold gas stream comprises a rotary regenerator 31 in association with a plate or tubular surface type heat exchanger (not indicated) located in a chamber 22 adjacent the hot gas inlet 21 and made of material capable of withstanding and transferring heat at a higher temperature than that of the regenerator 31. As shown, the matrix of the regenerative heat exchanger rotates within two chambers 29, 22, the latter containing the plate or tubular heat exchanger (not indicated) adjacent the hot gas inlet 21. This gas, after pressing through the two heat exchangers, discharges at 23. Gas to be heated enters at 27 and flows through the regenerator 31 from. which the now heated gas passes via chamber 29 to the outlet 30. The temperature of the heated gas may be varied by admixture in chamber 29 with another gas stream flowing to said chamber via a duct 28 and the plate or tubular heat exchanger in chamber 22. The degree of admixture and hence the temperature of the heated gas may be controlled by a damper (33, Fig. 2) in the duct 28, or by regulating the speed of gas flow. In a modification, the duct 30 is omitted and the duct 28 becomes the outlet for heated gas.

Patent GB-721053-A (GB)
Title: Improvements in the manufacture of cellulose products
IPC: C08B1/08
Filed: 1952-03-06
Abstract: A glycol ether of formula R(OCH2CH2)xOH, where R is an alkyl radical with 1 to 6 carbon atoms, or phenyl or benzyl, and x is 1 or 2, is incorporated into wood pulp during its manufacture prior to completion of drying.  The ethers may be added in amounts from 0.02 to 0.50 per cent by weight based on the dry weight of the pulp. Specified ethers include the ethylene glycol monoethers of 2-ethylbutanol-1, n-butyl alcohol, ethyl alcohol, methyl alcohol, phenol and benzyl alcohol and the diethylene glycol monoethers of 2-ethylbutanol-1, n-butyl alcohol, ethyl alcohol and methyl alcohol. Of these, the diethylene glycol monoethers of alcohols containing 4-6 carbon atoms are preferred.  Straight- or branched-chain alcohols may be used to form the ethers.  The mixture obtained in the etherification reaction (from ethylene oxide and the appropriate hydroxy compound) may be used, if desired, without removal of the traces of higher polyglycol ethers which are formed, but traces of alkali from the catalyst may be neutralized.  The ethers, in water solution or dispersion, may be added at any stage prior to completion of drying, for example, to the bulk pulp before sheet formation by spraying the pulp, or to the wet pulp sheets in the machine by sprays or rolls, subsequent to the removal of excess water, or even while the sheet is passing through the drier rolls. The treated pulp reacts more easily with acylating agents and with alkali (as in the preparation of alkali cellulose for viscose). Tables are given showing the increased reactivity (1) in the production of cellulose acetate, of pulp treated with 0.5 per cent of n-butyl diethylene glycol ether, and (2) in the production of viscose, of pulps treated with 0.04 per cent of n-butyl diethylene glycol ether and 0.04 per cent of ethylene glycol metal ether. Specification 721,052 is referred to.
