Title: An elastic wave generator
IPC: G10K5/00
Filed: 1964-02-24
Abstract: 1,026,713. Whistles. TEKNIKA Inc. Feb. 24, 1964 [April 8, 1963], No. 7641/64. Heading G5J. An elastic wave generator of the kind in which a jet of gas is directed from a nozzle into a resonant cavity, has a radial Venturi passage surrounding the space between the nozzle and cavity openings, through which the gas is exhausted. The radial passage formed by the cone-shaped faces 56, 51 acts as a divergent nozzle open to the atmosphere to cause the pressure of the gas in the nozzle cavity region to be less than ambient. According to the Specification this improves the performance of the generator. The distance between the cavity base and the nozzle opening is adjusted by moving the cavity body 60 along the axis. The plug 72 provides an annular gas passage in the nozzle. By means of the shaped faces 56 and 51 and reflector 82 the elastic waves are directed forwardly of the generator. In further embodiments the faces forming the Venturi passage are plane (Fig. 1, not shown) or are concave and convex (Fig. 2, not shown). When the cavity body is fixed a plug slidable in the cavity provides adjustment of the distance of cavity base to nozzle (Fig. 4, not shown). By using secondary cavities in addition to the main one harmonics are produced.

The distribution of glass in a glass article is determined by investigating the pattern of electromagnetic radiation emitted or absorbed by the article by locating the article near a concave mirror at the focus of which is a radiation detector. The absorption pattern is measured by a heat source 14, Fig. 3, and a concave mirror 3 and detector 4 such as a Pb-Se cell mounted on a slidable support 11. The glass article 2 is rotated and mirror 3 rocks to provide a scan, and any flaws such as voids which are detected are indicated or used to reject the defective article. When the source is retracted from the article, the attenuator 15 corresponding to a minimum acceptable thickness of glass is between the source and mirror and calibration takes place automatically. Emission measurements on still-hot articles may be made by locating concave mirrors on either side of a conveyer. The associated detectors feed separate amplifiers and meters or a common amplifier and meter alternately. Ultraviolet radiation or X-rays may be used instead of heat.

Filed: 1933-03-16
Abstract: 409,495. Protective cut-out arrangements. HASLEV, A. M., 9, Frederiksplads, Randers, Denmark. March 16, 1933, No. 8046. [Class 38 (v).] A combined leakage indicator and cut-out comprises a relay having two coils Vp, Vo arranged in two main feeders P, 0 and wound so that practically no resultant field is produced during normal conditions. When a leakage due to fault occurs, however, the resultant field attracts one or both of two armatures C, D, the former arranged to be attracted with a small leakage to complete the circuit across the mains of an alarm signal lamp L and the latter when the leakage increases to a larger value. The armature D completes the circuit across the mains of a coil B which in turn opens the main switch A and may also operate a switch F to complete the circuit of a visible or audible indicator E. In a modified arrangement, Fig. 2 (not shown), applied to a 3-phase 4-wire circuit, the relay has coils in each line wire and also in the neutral conductor so arranged and wound that upon an earth leakage occurring in any one of the phase conductors an external magnetic field is produced and with varying values of leakage one or both of the armatures is attracted. The circuit of the alarm signal L may or may not be arranged to be subjected to the protective action of the relay. Contacts K may be provided for testing purposes by means of an artificial fault.
