Abstract: 384,923. Grinding-machines. SÍHNS, W., 3, Raiffeisenstrasse, Poll, Cologne, Germany. June 20, 1932, No. 17402. [Classes 12 (ii) and 12 (iii).] In a grinding-machine, the bearings g, h of the grinding spindle a which are located in a rotatable head c, are placed n communication with a pump i supplying lubricant by means of a passage e leading to a circular channel formed by circular grooves m, n in the eontacting faces of the head c and a supporting column b the grooves registering in all positions of the head. Passages o conduct lubricant from the circular channel to the bearings. The support b functions as a lubricant reservoir and houses the pump and its driving mechanism. Lubricant returns to a chamber p directly from the inner ends of the bearings g, hand via passages r, s from their outer ends. Thence it passes through the bearings t, u of a vertical driving shaft d, which drives the shaft a through bevel gears f, to a spout v located above the teeth of a gear k. The pump i is located below a level mark y which can be seen through a glass wand is geared to the shaft d by gearing k, l. Leakage from the channel m, n is caught and returned to the reservoir by an outer circular channel x. A tube z extending round the shaft d above the mark y prevents lubricant escaping from the lower bearing hole. The circular channel may be formed by a groove in only one of the contacting faces.

Title: Process for the production of gases containing sulphur dioxide by simultaneous combustion of sulphur and hydrogen sulphide and for the production of sulphur trioxide andsulphuric acid therefrom
IPC: C01B17/54
Filed: 1956-06-08
Abstract: Gases containing sulphur dioxide are produced by simultaneous combustion of sulphur and hydrogen sulphide in the same combustion chamber without a catalyst.  A combustion chamber is used with at least one burner, each for liquid sulphur and oxygen mixture and hydrogen sulphide and oxygen mixture converging to meet in a central zone of the chamber.  The stoichiometric proportion of oxygen is injected through the hydrogen sulphide burner, and excess oxygen through the sulphur burner so that gas containing no free S, but oxygen sufficient for SO3 production, is produced.  Additional oxygen may be separately introduced into the combustion chamber.  The hydrogen sulphide gas may be that, containing CO2 and NH3, recovered from preliminary wash desulphurization of gases, and may be worked up at the same time as sulphur recovered in the final dry purification. Natural sulphur may be held in reserve to compensate for variations in H2S content to produce SO2 at a constant rate or a gas with a constant SO2 content, and flow control may be automatic.  Town, coke oven, generator, water, natural, or other combustible gas may also be burnt in a separate burner to maintain a temperature of 850 DEG  C.
