A support for each of the parallel roof tubes 2 of a fluid heater, such as a steam generator, comprises a U-shaped lug (5) having its limbs welded to the tube 2, and its base straddling a supporting bar 17 on which it is slidably mounted to allow for expansion and contraction of the tube 2. The bar 17 is welded to a transverse roof bar 14 which roof bar is supported from structural steel work by support rods 15. A thin gas-tight easing 8 is welded at its flange 19 to the roof bar 14, its free end resting on the tubes 2. The bottom edge of the roof bar 14 abuts the tubes 2 and prevents them from riding upwards due to excess pressure within the fluid heater. Two roof bars 14 together with an inverted U-shaped channel 13 define a gastight high crown seal through which steam superheating tubes 12 pass. In a modification, Fig. 1, the U-shaped lug is slidably mounted on a flat bar 7 which is welded at either end to the limbs of a transversely extending inverted channel member 4, the latter being suspended from the structural steel work by pipes 3. In this case it is the gas-tight casing 8 which prevents upward movement of the tubes 2.

Title: Mono (alpha-aryl)-substituted pyridinemethanols
Inventor: SWAIN ANSEL PARRISH
IPC: C07D213/30
Filed: 1957-07-16
Abstract: The invention comprises a process for the preparation of mono-(a -aryl)-substituted-pyridine methanols wherein a pyridine aldehyde is reacted with an arylmagnesium halide in a nonaqueous medium, together with a process for the preparation of a dialkylaminoalkyl ether of a mono-(a -aryl)-substituted-pyridine methanol by condensing a dialkylaminoalkyl halide with the said methanol when prepared by the first process.  The pyridine ring and the aryl substituent of the products and the starting materials may be substituted; one or more substituents may be present on one or the other or both rings; and these substituents may be halogen atoms, or alkyl, alkoxy or dialkylamino groups.  In an example, 2-pyridinealdehyde is added slowly to a solution of phenylmagnesium bromide in ether at a rate to maintain refluxing, the solution, after standing, being decomposed by hydrochloric acid, and made alkaline with ammonia to yield a -phenyl-2-pyridinemethanol.  Similarly p-chlorophenylmagnesium bromide forms a  - (p - chlorophenyl) - 2 - pyridine-methanol which is then reacted with 2-dimethylaminoethyl chloride and sodium to form 2-[p-chloro - a  - (2 - dimethylaminoethoxy) benzyl]-pyridine.  Th maleate is prepared by reaction of the base with maleic acid.

Abstract: 258,582. Erste B÷hmische Kunstseidefabrik Akt.-Ges. Sept. 17, 1925, [Convention date]. Cellulose acetates, nitrates, xanthates, and other cellulose solutions, processes for making filaments from.-In the manufacture of hollow artificial filaments solid or liquid particles are distributed in the solution to be spun or formed in the filaments during the process of manufacture, the particles being subsequently removed from the finished or partly-finished filaments by suitable solvents. The solid or liquid substance may be distributed as an emulsion or dispersion in a condition up to the colloidal state of dispersion. The process may be applied to the spinping of viscose and cuprammonia cellulose solutions as also to nitrocellulose and cellulose acetate solutions. Suitable solid or liquid substances are-oils, such as lubricating oil and paraffin oil; fats, waxes, solid paraffin, metal soaps, fatty acids, naphthenic acids, and resins. If the dispersed substance is to be formed in the filaments during the process of manufacture, then there is added to the spinning solution a substance which will give rise during the spinning operation, particularly under the chemical action of the precipitating bath, to the desired substance; thus, in the case of viscose solutions. there may be added the alkali metal salts of fatty or resinic acids &c., which decompose with the separation of the free acid under the action of the acid of the precipitating bath, the particles of free acid being subsequently removed by organic solvents or alkali solutions. In examples, bone oil or paraffin oil is finely emulsified in viscose solution, and the oil particles incorporated in the filaments are removed by means of benzene, carbon disulphide, or amyl alcohol; sodium oleate is dissolved in viscose solution, and the particles of oleic acid separated in the filaments are removed by benzine or soda lye.

Title: Temperature sensing and controlling apparatus
IPC: G03G15/20
Filed: 1974-05-22
Abstract: 1438256 Automatic temperature control; heat fusing arrangements INTERNATIONAL BUSINESS MACHINES CORP 22 May 1974 [12 June 1973] 22827/74 Headings G2H and G3R [Also in Division H2]  In a temperature control system for a heated surface, contact means are provided not only for sensing the surface temperature but also for monitoring the satisfactoriness of the sensing contact. The invention is particularly described with reference to the control of the surface temperature of a xerographic fuser roller (such as that described in Specification 1411458) in which poor sensing contacts arise from contamination of the surface by the fusing process. The roller 17 shown diagramatically in Fig. 4 is contacted at 13, the contact being thermally and electrically connected to a heat sensor 19 whose effect is to make or break a connection between lines 21 and 23. If the contact at 13 is poor, it will increase the resistance in the path, through the roller itself, to a second contact member 15. The latter, through a thermal cut-out 25, normally couples line 21 to line 27. A D.C. voltage is applied at C to line 21 and the resulting voltages at A and B are fed to the points shown in the control circuit of Fig. 5. The effect of this is to energize the lamp 45 (which is in fact a heater located inside the roller of Fig. 4) whenever a too-low temperature is sensed at 19, provided that the path 13-15-25 is continuous. The latter path, when broken, thus performs a 'fail-safe' function in response to roller surface contamination.
