Title: Improvements in or relating to microphones
IPC: H04R21/02
Filed: 1920-12-30
Abstract: 182,494. Gardner, J. Dec. 30, 1920. Microphones.-A microphone for detecting faults in bearings &c. comprises a rigid casing 4, 5 tapered to form a boss 6 with a socket for attachment to a stud 7 on the bearing. The electrodes 9, 10 are arranged concentrically and face in the same direction, and the inner electrode serves to clamp the outer electrode by the engagement of its head with the shouldered surface 13. The electrodes are bridged by carbon balls 14 disposed in a V-shaped groove. The rigid association of the casing 4 with the bearing causes the casing and its contained electrodes to partake of the vibrations of the bearing, and the inertia of the carbon balls 14 causes changes of contact resistance between the balls and the electrodes. In a modified form, the working faces of the electrodes are flat, and fine carbon granules are employed as the resistance-varying medium. In order that damping may be effected during excessive disturbances, the balls or granules may be pressed together and against the electrodes 9, 10 by means of a weight or spring.

Filed: 1934-12-22
Abstract: 454,216. Boiler &c. furnaces. VANDEVELDE, A., 25, Avenue Jacques Sermon, Brussels. Dec. 22, 1934, No. 36819. [Class 51 (i)] A process of generating heat by the combustion of small fuel consists in passing the fuel from a supply inlet 3 into a bed of fuel resting on the imperforate bottom 2 of a combustion chamber 1 and at a distance from the bottom blowing into the fuel bed a stream of air under such pressure and through an aperture so shaped and disposed that clinker 6 forms immediately at said aperture and only above the air stream, thereby creating a zone of intense combustion at the lower edge of the clinker so that the clinker interposes itself (as shown by the chain lines at 6a) in the most direct path from the air inlet 5 to the surface of the fuel 4 and causes the air flow to pass down around the clinker between the clinker and the bottom of the chamber and thence upwards to the fuel surface as shown by the arrows 7. The air inlet may comprise a nozzle entering the side of the combustion chamber or as shown in the Figure may comprise a central horizontal water-cooled pipe 8 open along its underside. Specifications 403,819 and 403,821 are referred to. Reference has been directed by the Comptroller to Specifications 403,819, 403,821, 415,290 ; and 430,382 (as open to inspection under Sect. 91 of the Acts).

Headings B7L and B7T. A rigid carrier member 1, Fig. 1, for a central buffer-coupler 2 has a straight edge 1a and support plates 8 securable to the end sill 3 of a railway vehicle frame, at positions where side buffers 5 are secured to the sill 3, whereby buffer forces acting at the central buffercoupler are transferred to the frame sole bars 4. The side buffers 5 may be omitted. In the embodiment of Fig. 2, the rigid carrier 1 has a central recess 9 for the central buffer-coupler 2 and a spring 10. The intermediate piece 7 of the buffer-coupler has inclined surfaces 12 engaging guide members 13, 14 slidable in lateral recesses of the carrier against the urge of springs 11.

The heat-sealable material is stored in a heated bath, and the roller 4 is also heated. The roller 4 has a circumference less than the length of a wrapper and is an engraved gravure cylinder, excess heat-sealable material being removed from the roller 4 by a doctor knife 10. Alternatively the roller 4 receives heat-sealable material from an intermediate roller which dips into the heat-sealable material.

Filed: 1929-12-05
Abstract: 339,488. Hoe & Co., Ltd., R., (Hoe & Co., Inc., R.). Dec. 5, 1929. Inking-apparatus; damping-apparatus.-In order to distribute evenly the ink on a long inking-cylinder 11, or water on a damping-cylinder, a flexible distributing-roller 12, which may be formed of a metal core covered with composition or with rubber, is supported in such a manner relatively to the inking &c. roller that it bears with substantially equal pressure throughout its length upon the cylinder 11. This is effected by supporting the roller 12 with its axis askew. The bearings for both ends of the roller are placed at the same distance from the axis of the cylinder, but one bearing is angularly displaced in relation to the other with respect to the axis of the cylinder as shown diagrammatically in Fig. 3, in which 23 indicates the axis of the cylinder, and 24, 25 the centres of the two ends of the roller. The roller contacts with the cylinder along a helical line, and by varying the pitch of the helix, a pitch will be found that will cause the roller to bear against the cylinder with equal pressure throughout their line of contact. Two distributing-rollers may be used which are set askew in opposite directions to cause the ink to move spirally along the surface of the cylinder from right to left and then left to right. The roller 12 is reciprocated longitudinally by means of an oscillating lever 15 with a roller 16 engaging flanges 17, 18 on a collar 19 attached to the shaft of the roller 12.

The organic solvent may comprise methyl or ethyl alcohol or acetone singly or in admixture. The support may be of slightly esterified cellulose or of regenerated cellulose and may be sensitized by a mixture of a diazo compound and a phenol with or without a metallic salt capable of forming a lake with the azo dye, the developer being ammonia or caustic potash in the above solvent. The support may contain only the diazo body, the developing bath then containing an amine or a phenol. The solvent may be used in tinting and toning processes, for washing the films free of the products of developing or for incorporating fireproofing or softening agents in the film.
