Patent GB-1504537-A (GB)
Title: Automatic inspection of machined parts
IPC: G01B11/02
Filed: 1975-06-12
Abstract: 1504537 Automatic inspection of machined parts INDUSTRY SECRETARY OF STATE FOR 4 June 1976 [12 June 1975] 25273/75 Heading G1A In an apparatus for the automatic inspection of an axially symmetric conponent 18 in a groove 9  of a rotating annular transparent plate 5, radiation from a quartz halogen light source 15 is directed as shown in Figs. 1 and 2. Thus a "shadow-image" is projected by lenses 31, 32 on to a vidicon tube or a line of photo-diodes 34. The resulting electrical signals are fed via timing logic TL, control logic CL and a threshold detector to an interface unit IU in a computer processor CP. The annular plate 5 is supported on a turntable 1 whose spindle 2 supports a radial diffractor grating 35. At the periphery a light source 39 an index grating 36 and a photodiode are arranged. Each time that the diode 40 detects a null-intensity of the beam from the source 39, a pulse P is sent to the interface unit IU which relays a "START SCAN" signal to the vidicon tube or the array 34. The resulting data is processed by a processing module PH according to flow diagrams Figs. 3 and 8 (not shown). The module PM is connected to a keyboard K and may supply a visual display unit VDU, an accept/reject facility AR, and an alarm unit AU. The description discloses formula and methods concerned with overcoming the effects of distortion of the video image. The distortion is caused by the component 18 moving in a circular path so that successive "scans" are at an angle relative to one another.

Title: Improvements in and relating to ultrasonic nebulizers
Inventor: BEST CLEAFE A
IPC: B05B17/06
Filed: 1969-05-20
Abstract: 1,270,700. Spray-producers. SANDOZWANDER Inc. 20 May, 1969, No. 25652/69. Heading B2F. [Also in Division H1] In an ultrasonic nebulizer, Fig. 2, water, fluid or drug composition is atomized to droplets between 1 and 8 microns in size by a pieza-electric crystal vibrating at approximately 1600 kilocycles per second and the dense mist or fog produced rises through a tubular baffle 154 to the outlet 150. The composite volume of mist or fog may be increased by admitting some air from a fan outlet (42 Fig. 1, not shown) through a radially directed tubular inlet (152) in the rotatable cap 148, the amount of air taken in being determined by the relative alignment of the radial inlet with the fan outlet. The admitted air passes down through the annular space surrounding baffle 154 before mixing with the mist or fog and passing out of the chimney 150. Liquid flows into the nebulizer from a reservoir 14 along a passage 96 which incorporates a non-return valve. When the supply of liquid is exhausted, the float 50, Fig. 3, in the reservoir will have dropped sufficiently for the magnetic contact unit S 2 , Figs. 2, 3 and 4, to be closed under the influence of permanent magnet 48 on the float, whereby energization of the oscillator is prevented. The vibratory crystal assembly comprises a pieza-electric crystal X b , Fig. 2, bonded by epoxy resin adhesive to a plate X a  of heat- and chemical-resistant glass. Spring 70 provides both a mechanical and electrical connection between the contacts 72 and 74 of the power oscillator Q 4  and the crystal, respectively. The volume of mist or fog generated can be varied between zero and, say 5 cc./min.- by adjusting the resistor R 7  in the unijunction charging network of the power supply circuit depicted in Fig. 4. The circuit includes a first silicon-controlled rectifier SCR 1 , a unijunction Q 3  and charging network R 6 , R 7  and C 2  which determines the firing angle of SCR 1 . The rectifier is gated "on" later in the cycle where the output voltage from it is down to 21 V. The application of an abnormal positive bias voltage to the base of transistor Q 2  e.g. at the closing of magnetic contact unit S 2 , renders it conductive and so inhibits the action of the charging network. The circuit includes a second silicon-controlled rectifier SCR 2  responsive to excessive current loads. (For Figures see next page)
