Title: Improvements in or relating to vibratory apparatus
IPC: B06B3/00
Filed: 1944-07-18
Abstract: 594,078. Jigging-conveyers. STEVENS, A. H. (Syntron Co.) July 18, 1944, No. 13736. [Class 78(i)] [Also in Groups XXVI and XXIX] Vibratory apparatus e.g. for jigging conveyers comprises a fluid-pressure chamber with inlet and outlet connections, a diaphragm at one end of the chamber, an operating valve controlling the flow of fluid through the outlet connection, a lost motion device comprising a resilient member connecting the diaphragm with the valve, and means connecting the diaphragm with the object to. be vibrated. Fig. 1 shows the application to a jigger conveyer wherein the trough 182 is supported by members 193 on leaf springs 192 extending between a pair of flanges 185 on a base 177, and is connected by a strap 181 and bar 172 to a diaphragm 167 of a fluid-operated motor. The diaphragm is mounted at the end of a housing 139 between a plate 166 and a block 168 which is connected by a rod 164 to a sleeve 161 pivotally connected by a bolt 165 to a clevis 156, the bolt engaging a bush 163 surrounded by a rubber sleeve 162. When gas or liquid under pressure is admitted to the housing 139 through a pipe 141, the outlet valve 148 is closed and limited outward movement of the diaphragm against the pressure of the springs 192 is effected by compression of the. sleeve 162. Continued pressure then effects further outward, movement of the diaphragm to open the valve 148. Pressure in the housing being relieved, reverse movement of the diaphragm is effected by the springs 192 and the valve 148 closed again to allow build-up of pressure. A throttle valve 198 and a pressure regulator 199 is provided in the inlet pipe 141 to adjust the amplitude and frequency of vibration. In the modification shown in Figs. 2, 3 the trough 182 is supported on a base 177 by springs 247 and is secured to the diaphragm 167 of the vibratory motor by a spring strap 181, adjustable coupling member 259 and bar 172. The diaphragm is secured at the end of a casing 139 on an angle bracket 204 between a block 168 and a plate 208, the latter being connected to the stem 214 of the outlet valve 148 of the casing. A plate 215 on the stem is held supported in a bore in the plate 208 between rubber washers 212, 218 by a plate, 219. Rubber tubes 231, 232 around the plate 208 serve as a cushion to eliminate water hammer. The vibration of the motor may be varied by adjustment of a spring 238 on a post 235 by a nut 242.

Title: Improvements in or relating to acoustic or compressional-wave directive signalling
IPC: G01S1/72
Filed: 1918-08-26
Abstract: 139,530. Fessenden, R. A. Aug. 16, 1917, [Convention date]. Audible signals; locating sounds; subaqueous sound signals.-Apparatus for the transmission and reception of acoustic waves, described as particularly for directional signalling, and for the location of submarines and submarine signalling- stations, but stated to be applicable also to locating aeroplanes, comprises sound signalling-mechanism placed in liquid in a tank the walls of which are arranged to have the same refractive index for sound as that of the medium outside the tank. Two sound-detectors placed in liquid in a tank are independently connected electrically to two indicators. The receivers may be separated by a sound screen producing the same shadow with relation to the detectors as the human head produces with relation to the ears. As shown, two detectors 11, 12, which may be microphones, stethoscopes, or electro-magnetic receivers, but are preferably oscillators of the kind described in Specification 18765/13, are separated by a soundinsulating screen 13 with an extension 14, the shape of which is determined by experiment. The detectors are placed in a tank, or adjacent tanks, containing oil or water, extending across a ship and separated from the bow and stern by air chambers. The detectors and screen are rotatable about a pivot 29. The detectors are independently connected to telephone receivers 26, 27 on a head-piece through circuits each including a switch 34, 35, adjustable capacity 22, 23, and inductanca 24, 25 by which phase-difference may be adjusted. To give the walls of the tank the same refractive index as the water outside, they are loaded with weights 40 of lead, tungsten, zinc, tin, tin alloyed with lead, or other material, or plates may be used having punched holes filled with lead or brass. The distance between the weights should not exceed a quarter wave-length of the sound to be received. The distance between the detectors should bear the same ratio to the distance between the human ears as the velocity of sound in the medium in the tank bears to the velocity of sound in air.
