Title: Improvements in and relating to centrifugal fans
IPC: F04D29/30
Filed: 1958-03-17
Abstract: 848,131. Centrifugal fans. SELBACH, A., AMME, P., and AMME, W., [trading as POLLRICH & CO., P.]. March 17, 1958 [March 25, 1957], No. 8414/58. Class 110 (1).  In a centrifugal fan with a drum-type impeller in which the outlet ends of the blades are curved forwardly into the direction of rotation, the blade exit angle #2, Fig. 5, is between 0 and 10 degrees, and the camber angle α is between 115 and 145 degrees. The use of a small exit angle #2 ensures that the direction of the absolute exit velocity does not deviate sufficiently from the tangential direction at high mass flow to cause energy losses by breaking up the vortex motion about the impeller eye within the casing induced by the current of air leaving the impeller. The exit angle #2 may be negative, i.e., the outlet ends of the blades may be curved forwardly beyond the point at which #2=0. The camber angle α is sufficiently large to cause the flow channels to converge towards the blade exits (after a slight initial divergence), as shown in Fig. 7, so as to produce an acceleration that suppresses flow discontinuities and turbulence. The blade inlet angle #1 is preferably 40 to 50 degrees, sufficiently large to give large flow coefficients at low speeds of rotation.

Title: An improved photo-electric exposure meter
Inventor: POIRETTE PAUL
IPC: G01J1/42
Filed: 1954-03-24
Abstract: 755,264. Photo-electric exposure meters. SOC. MAROCAINE D'ACHATS & DE CONSTRUCTIONS, SOMARAC SOC. ANON. March 24, 1954, No. 8557/54. Class 40 (3). [Also in Group XXXVI] In a photo-electric exposure meter the needle is arranged to traverse a scale uniformly for uniform increments of light intensity, the scale being movable in accordance with a second variable to indicate shutter speed and aperture directly. As shown, photo-electric cell Z feeds the coil of a moving coil meter 13 through a calibration resistor 8. The meter is so designed that each time the light intensity increases by a factor of two the needle 9 traverses one division of a uniform scale representing aperture values. The Specification states that the output of some photo-electric cells is such as to lead to crowding at the end of the scale and to make the scale uniform the central core of the instrument has a cut-away portion 10a while on the upper side of one polepiece is a cut-away portion P<SP>1</SP>a and the lower side of the other is a cut-away portion Pa. In addition magnetic shunt S may be advanced towards the centre and may also be rotated so as to determine precisely the degree of weakening of the field which the cut-away portions are intended to produce. In addition the field is strengthened at the end of the pointer travel by a polepiece extension S<SP>1</SP>. The scale plate which rotates about the same geometrical centre as the pointer has two scales of aperture values, each scale corresponding to a different shutter speed and the whole scale plate may be rotated by means of a projecting lug 12 so as to position a fixed mark B against a scale representing emulsion speed when the portion of the pointer on the aperture scale corresponding to the desired shutter speeds gives aperture value directly. Scales graduated in shutter timings corresponding to fixed aperture values may be used while in an arrangement suitable for cinematography the emulsion speed scale is replaced by shutter speed and the aperture values are read against scales corresponding to fixed emulsion, speeds. The slot n, n<SP>1</SP> in the bottom of the instrument enables the dial to be replaced, by one bearing a different range of values. A translucent lid 1 is provided for the instrument reducing the light reaching the instrument by a predetermined factor enables it to be used both for direct and reflection measurements. An opaque insert 5 is provided for the lid.

Filed: 1919-04-04
Abstract: 150,761. Anderson, R. J. April 4, 1919. Shaft furnaces; reverberatory furnaces; chemical manufactures, furnaces for. -In a furnace fired by liquid, gaseous or pulverulent fuel and applicable to various industrial purposes, jets of air and fuel are projected in cross-wise relation into a closed combustion chamber whereby thorough mixture and complete combustion are obtained. Figs. 1 and 8 show the application to a copper-smelting furnace, and Fig. 11 to a reverberatory furnace. Air is supplied by refractory pipes 15 perforated all round and extending across the combustion chamber and fuel by nozzles 22 directed longitudinally of the chamber, and thorough mixture is further ensured by the staggered relation of the air pipes and of the fuel jets as shown in Fig. 8, and by the fact that both air and fuel jets are in planes substantially at right-angles to the outlet from the chamber. The air and fuel can be precisely regulated, and in the case of a foundry cuploa furnace, for instance, it is thus possible to ensure an atmosphere with a slight excess of carbon, thus minimizing oxidation losses. In addition to the applications dealt with above the production of Portland cement, of glass, and of sodium oxide from sodium sulphate is mentioned.
