Filed: 1932-07-13
Abstract: <PICT:0390984/III/1> The oil heating-furnace described in the parent Specification is provided with an economizer 12 for preheating the fluid under treatment and a preheater 13 for the combustion air, the preheater being shielded from the radiant heat in the heating chamber 16 by the economizer.  A conical well 28 arranged below the heating chamber is supplied with liquid, gaseous or pulverulent fuel by tangential burners 30, air for combustion passing through the open bottom of the well from a chamber 10 supplied by a pipe 26 from the air preheater.  The fluid to be heated enters the economizer at 46 and leaves through an outlet 48 connected to the heating tubes 27 mounted in the heating chamber. Fig. 3 shows a method of supporting the tubes 27 from their lower ends to allow for free expansion, each tube being provided with an annular groove 33 in which takes a two-part washer 34 fitting in a recess 37 of a ring member 35 resting upon the bottom wall 19 of the heating chamber.  In a modification, Fig. 5, a washer 49 is welded to the lower part of the tube 27 and rests on the flange 56 of a ring 51 in two parts secured together by bolts 54 the ring 51 resting on the bottom wall 19.  Packing 57 prevents gases escaping from the heating chamber.  The tubes 27 are connected in parallel or in series by junction boxes 38 engaging the ends of the tubes and provided with removable plugs 40 for cleaning. The lower ends of the tubes with the junction boxes are contained in an annular chamber 41 secured to the underside of the bottom wall 19 and provided with closure members 42.

Abstract: 337,796. Durium Products Corporation, (Assignees of Beans, H. T.). April 2, 1929, [Convention date]. Records, materials for.-Sound-record blanks are made with a core of paper material, such as cardboard made of rag stock, coated with a resorcinol formaldehyde condensation product in which a plasticizer, preferably glycerine, is incorporated to avoid brittleness, and the record surfaces may be impressed in a printing press of the embossing type carrying several heated dies for producing several records simultaneously on the blank material. When record material is applied to one side only of the blank, the other side is varnished to prevent curling of the records when separated from the embossed blank. The record material is made by heating and stirring 1000 c.c. of commercial formaldehyde with 1000 grame of ground commercial resorcinol (meta dihydroxy benzene) to a temperature of 70‹ C. until the required viscosity is obtained, and then adding 1000 c.c. of ethyl or methyl alcohol or a mixture thereof. After rapid cooling, an abrasive for example 200 grams of rouge ground in glycerine is added, and the resulting mixture is applied at once to the paper stock which is subsequently dried until a slightly tacky surface is presented. The blank is then impressed by dies heated to about 160‹ C. which may be lightly coated with paraffin to prevent sticking. The composition of formaldehyde and resorcinol without the rouge may be used as the varnish on the side of the stock not intended to carry a record. Reference has been directed by the Comptroller to Specifications 3497/11, [Class 95, Paints &c.], 607/13, and 219,368.
