Title: Improvements in or relating to sound reproducers
IPC: H04R9/06
Filed: 1929-02-06
Abstract: 305,543. Schlenker, V. A. Feb. 6, 1928, [Convention date]. Loud-speakers; diaphragms. - The shape of the periphery of the diaphragm, of a large-diaphragm loud-speaker is such that the wave-fronts of the vibration waves set up in it by the driving unit axe linear after reflection fmom said periphery. The periphery of the diaphragm is preferably in the form of intersecting parabolas, the latter having a common focus at the point where the diaphragm is energized. Thus, vibration from K, Fig. 9, travelling along paths such as KP, KP1, EP2 and EQ, KQ1, KQ2 are reflected along parallel paths and meet simultaneously on the line KB where provision is made for damping them out. The diaphragm thus acts as one of infinite size, as far as vibrations reflected from the periphery to the driving point are concerned. In the construction shown in Fig. 1, a framework 1, of the shape shown, consists of two clamping rings provided with bolt holes 32. between which the aluminium alloy diaphragm 30 is clamped under tension. Damping material 42, such as felt, is applied to the diaphragm in the places shown, being held in position by the braces 16 - - 23, while further braces 6 - - 9 integral with the frame, support a special type of pot magnet 37 which provides the field for the moving coil. Figs. 10 and 12 show the magnetic system in which 37 is the pot magnet, which may be permanently magnetized or energized by a coil wound in the gap 43, 40 is the outer annular pole piece, 34 is the moving coil wound on a conducting ring 35, and 30 is the diaphragm. Fig. 12 also shows a method of arranging the connecting leads to the coil, in which 71 (also shown in plan in Fig. 12a) is a silk ribbon with narrower phosporbronze strips 72, 73 secured thereto and passing through a hole 70 in the pole piece 40, the hole being packed with damping material 76. One end of the ribbon leads to the coil 34 and the other to a terminal block 74 fixed to a rigid member of the framework. One lead only may be carried on the ribbon and the circuit completed through the metallic diaphragm, or still further the two leads may be fixed to and carried across the diaphragm to a terminal block on the frame. In another modification, the diaphragm 80, Figs. 13 and 14, which may be built up of layers of balsa wood having their grains crossed, is not clamped but is supported by a strip of resilient material 83.

Title: Improvements in or relating to lubricating apparatus
Inventor: EDGE STANLEY HOWARD
IPC: F16N27/00
Filed: 1953-02-12
Abstract: 738,188. Lubricating. CLAYTON DEWANDRE CO., Ltd. Jan. 20, 1954 [Feb. 12, 1953], No. 4007/53. Class 12 (3). In a lubricating apparatus of the kind in which a lubricator is operated at intervals to discharge lubricant under pressure through a number of outlets to several points requiring lubrication, the volume of lubricant delivered to any one or two points can be reduced by the provision of a valve device containing a pistonvalve element which is operated by the pressure of lubricant to supply through a first outlet a quantity of lubricant less than that discharged through the lubricator and then supply through a second outlet lubricant remaining under pressure on the inlet side of the valve. The valve device shown comprises a housing 1 provided with screw-threaded sockets 2, 3 to enable the device to be interposed between the lubricator (not shown) and the point requiring to be lubricated. A bore 4 between the sockets is fitted with a piston 8 which is formed with a stem portion 9 and an axial passage 13 communicating through a transverse passage 14 with a circumferential groove 15. The bore 4 communicates with a passage 7 leading to an outlet 6 adapted to be connected to another point requiring to be lubricated, to the inlet of the lubricator or to the lubricant reservoir. The stem portion 9 has a coned valve face for engagement with an annular valve seat 11 surrounding a reduced portion 5 of the bore 4. Lubricant supplied under pressure to the valve inlet 2 presses the piston 8 inwardly against the action of a spring 12 and lubricant is forced out through the outlet 3. When the stem 9 engages the valve seat 11 the groove 15 in the piston 8 registers with the passage 7 so that some of the lubricant is discharged through the opening 6. When lubricant pressure is released the piston 8 slowly returns to its normal position lubricant passing from the inlet 2 between the periphery of the piston and the inner surface of the bore 4 and into the space enclosing the spring 12.

Abstract: 684,896. Centrifugal separators. BLACKCLAWSON CO. Feb. 20, 1951 [May 20, 1950; May 20, 1950], No. 4098/51. Class 23 [Also in Group XXX] A vortex separator for separating heavy particles from a liquid slurry stock has a casing filled with liquid, a supply port for the stock and an outlet for the lighter material in axial alignment, and an annular discharge gap leading to the latter outlet. In Fig. 1 incoming mixture from a pipe 22 is whirled around a helix 26 having a core 25 of increasing diameter, the lighter material crossing a gap 30 and passing out through an outlet 15 into which the core extends. Heavy material is flung to the inner wall of a chamber 11 and flows downwards for discharge past a weighted door 45, by means of a worm conveyer 40 driven by a motor 42. The end of the worm is at some distance from the door 45 so that a plug of material in the space forms a seal and is slowly forced out of the doorway. Clean water is supplied from an inlet 50, under control of a valve 51, and whirls upwards through the chamber 12 and washes the downcoming heavy material. The valve 51 may also be used to draw off water, if required. The water makes up for the material discharged through the outlets and prevents a pressure drop in the chamber. Fig. 2 shows another arrangement in which the inlet pipe 130 extends to a part 133 where a vane 137 starts an upward whirl of mixture through an annular space 135. The lighter substance passes up a gap 122 into a vortex discharge chamber 13. The heavier material flows downwards to a worm discharge rotor 177, a door 164 being loaded into the closed position by an external weight acting through links 171, 170, 167. Clean water is supplied from a pipe 145. The length of the gap 140 may be adjusted by vertical movement of the pipe 130. Dimensions of various parts of the separting chamber and the tubes, and the rates of flow of the water, are given in the Specification.
