Abstract: 901,464. Ultrasonic whistles. SPIN-SOC. DE PROCEDES INDUSTRIELS NOUVEAUX. Dec. 3, 1958 [Dec. 3, 1957; Sept. 27, 1958], No. 39016/58. Class 13. [Also in Group II] Resonant cavities are formed by stacking sheets so that cut-out portions of alternate sheets are bonded by imperforate portions of intervening sheets. Thus cavities 30 are formed between sheets 38, Fig. 12, of stainless steel when stacked alternately with sheets 37, Fig. 11, of polytetrafluorethylene. The cavities serve as Galton's whistles which set the fluid into vibration at ultrasonic frequencies. The arrangement may be used for mixing fluids, for cleaning metallic wires or for sintering metallic powders. Corresponding apertures 40, 39 and 42, 41 in sheets 37, 38 form ducts 28, 33, Fig. 7, for the supply and withdrawal of fluid. The stack is held between stainless steel end-plates 46, Fig. 16, by means of bolts 47, or may be held together by epoxy resin. Fluids to be mixed are supplied through inlets 45, Figs. 13, 16, in discs 44 in the middle of the stack and the mixture is withdrawn through the manifold 54. The sheets 37 may be so stacked as to provide clockwise and anticlockwise circulation of the fluid alternately in the central duct 33. The arrangement may be used for cleaning a wire W running along the duct 33. A number of patterns like that on Fig. 11 may be cut in each sheet 37 of a stack. Sheets may be stacked so as to radiate from a central cylindrical duct into which the fluid is discharged. In Figs. 3, 4 each stack 4 of cut-out strips is closed at the sides by V-shaped plates fastened to the sides of the stacks by clamps 4m, leaving apertures (not shown) for the fluid to enter the cavities 5 from the input 12. The fluid flows from cavity 5 into cavity 6 and discharges into the central duct through outlet 7. In another arrangement, Fig. 5, fluid entering inlet 20a flows through orifices 17a and chamber 17 and is directed into cavities 18 by a conical head on shaft 16.

Title: Photoelectric surface scanning device
IPC: G01N21/89
Filed: 1973-08-21
Abstract: 1399298 Photo-electric flaw detectors E SICK [trading as ERWIN SICK] 21 Aug 1973 [14 Sept 1972] 39436/73 Heading G1A In a flaw detection system using an arrangement for line scanning a light beam across a surface the reflected or transmitted light being detected and the signal applied to a differentiator connected to a circuit for producing output pulses indicative of flaws, a signal lock is provided which inhibits the output while the beam does not strike the surface and a circuit which stores a signal while the surface is being scanned and applies this signal to the input of the detector while the signal lock is in operation. A moving web is scanned by projecting a beam of light via a rotating mirror drum, a system of mirrors and a cylindrical lens and the reflected light returns along the same path to a beam splitter and a detector. Two photo-cells are positioned beneath the web at its edges to detect when the scanning beam passes across the edges of the web. As shown, Fig. 2, the output of the photo-cell 30 is applied to a differentiator 42 which detects sudden changes due to flaws, a threshold circuit 44 producing an output pulse. The two photo-cells 34, 36 produce pulses which set and reset a bi-stable 50 which locks out the output of pulses from circuit 44 by means of AND gate 48 while the scanning beam is off of the web. This removes pulses due to the edges of the web. A storage element 68, 70 is charged over switch 62 while the web surface is being scanned to provide a signal equal to the mean value of the input signal and this is applied via buffer amplifier 56 and switch 64 to the input of the differentiator instead of the ouput of the photo-cell 30 when the signal lock operates thus suppressing sudden changes in the  D.C. level as the edges of the web are crossed.
