Title: Improvements in or relating to hydro- or aero-dynamic oscillation systems and apparatus
IPC: G10K9/18
Filed: 1929-05-02
Abstract: 334,835. Rydberg, H. S. A. May 2, 1929. Concussion-preventing and relief devices.-In apparatus or systems wherein a pressure fluid is set in oscillation, means are provided to prevent back feeding of the oscillation into the fluid supply pipe. The invention is applicable to pipe lines connected with fluid-pressure driven motors, pumps, turbines, pneumatic tools, and the like, but is described more particularly with relation to acoustic signalling apparatus wherein the pressure fluid produces audible oscillations by the aid of diaphragm, oscillating piston, rotor, or the like, or without such. member. One or more resonators designed to perform regular oscillations of a certain frequency under the influence of an oscillation of the same frequency are placed adjacent the apparatus in the supply pipe at such a point or in such a direction relative to the direction of movement of the oscillations as to produce a node or anti-node in the oscillations at the inlet into the pressure fluid supply pipe. If there is a nodal point at the inlet, a porous wall may be inserted in the fluid supply tube; if there is an anti-node at the inlet, the inlet may consist of one or more holes through a wall of the tube at an anti-node, or the pressure fluid may be introduced in a direction substantially at right-angles to the main directions of the oscillation at the anti-node in the resonator. As applied to an acoustic signalling apparatus of known type comprising a vibrating diaphragm B, Figs. 12, 13, the fluid supply pipe adjacent and external to the casing of the apparatus is formed of T-shape and comprises two branch pipes T<2>, R, communicating with a stem pipe T<1>, the pipes R, T<1>, being adjustable relatively to one another. The branch T<2> leads radially through the annular relief chamber within the casing A to an outlet chamber T' adjacent the diaphragm and the other branch R is in the form of a resonator with a closed end at r<1>. The length of the resonator R is such that an anti-node point occurs at the point x in the supply pipe. In an alternative form of acoustic signalling apparatus, Fig. 14, the resonator pipe R is mounted internally and coaxially of the fluid supply pipe T, the two being arranged so that an anti-node occurs at the mouth of the resonator. As a modification, the resonator pipe R could be extended as indicated by dotted lines and the end r' closed and an inlet hole x<1> provided at an anti-nodal point. Alternatively, a perforated or porous throttling disc S may be mounted in the fluid supply pipe T, which may be considered as a resonator. Eccentric holes s may be provided in the disc S and arranged at the bottom to prevent collection of condensed water in the pipe T.

Abstract: 703,908. Sawing wood &c. ROBERTSHAW, E. G. F. Aug. 31, 1951 [June 1, 1950], No. 13679/50. Class 145 (2) A machine for presenting an article to a saw of the circular, band, or reciprocating types, includes a reciprocable two-part clamping device, one part of the clamping device gripping the article on one side, and the other part of the clamping device gripping the article on the other side, of the plane of the cut, the parts having automatic and independent relief mechanisms responsive to the position of the clamping device relative to the saw. The upper and lower carriages 10a, 10b are mounted for reciprocating movement on a frame 11 and are reciprocable by means of a lever 12 pivoted at 13 to the upper carriage 10a. A first link 14 is pivotally connected to the lever and to a projection 15a on a transverse bar 15b attached to a cramping ram 15, reciprocating on the upper carriage, and carrying a clamp 16. Blocks 17a, 17b are mounted on the forward ends of the upper and lower carriages respectively. A second link 19 is pivoted to the rearward end of the cramping ram and to a third link member 20 which latter is pivoted to the frame. A lever 23 is pivoted at 23a to the rearward end of the upper carriage and rests on the transverse bar 22a carried on a presser 22 pivoted at 13. The saw 26 projects into a slot 16a when the device is moved to the right. The support 29 for the wood may be raised or lowered by a lever 33. To operate the device the hand lever 12 is pivoted in an anti-clockwise direction causing ram 15 to move away from the hopper walls 27, 28 and in its further position the end of link 20 presses on the lever 23 to push the lower carriage forward slightly. The article is now inserted. Lever 12 is now moved forward (clockwise) and the spring 24 displaces the ram and clamp 16 to clamp the wood against the hopper walls 27, 28. Further movement causes the two carriages to slide forward allowing the saw to cut the work. Further forward movement causes bar 19a to press downwardly upon the presser 22 causing bar 22a to engage the rear end of the lower carriage to displace it forwardly independently of the upper carriage so that the portion of the article below the cut is released. The cycle is then recommenced. The cut can be made at an angle to the axis of the work by giving the support 29 a transverse inclination.
