IPC: G01N21/90
Filed: 1967-09-01
Abstract: 1,196,277. Photo-electric flow detecting apparatus. COMPAGNIE DE SAINT-GOBAIN. Sept. 1, 1967 [Sept. 1, 1966], No. 40188/67. Heading G1A. In an apparatus for detecting crazing in the neck of a stationary glass container Fig. 2, comprising an optical system 9, 10, 11 arranged on a rotatable mounting 16 and receiving light from a stationary source 12 situated on the axis of rotation of the mounting, the optical system is arranged to concentrate the light, and by reflective means to direct it at a predetermined angle on to the container 1 so that pulses of light are received by an appropriately positioned light sensitive cell 22 when the incident beam falls upon a crazed portion. The mounting is driven by a motor 32 through a pulley 31, and external connections are taken off by slip rings 26 and brushes 30, the space 24 behind the cell 22 housing a fire amplifier. The apparatus described is for detecting horizontal crazing and an arrangement for detecting vertical crazing is described with reference to Figs. 4 and 5 (not shown), the rotating mirror portion in the latter being liftable by a rollered fork to permit the insertion and removal of containers. Square or circular lamp filaments may be used, and mirror angles are exemplified. Separate heads may be provided for inspecting different parts of the container, and the circuits may include filters for rejecting unwanted pulses due to seams or threads.

Title: Apparatus and method for detecting submicron sized particles
IPC: G06F17/18
Filed: 1974-09-16
Abstract: 1481451 Measuring the mass and distribution of particles BLOCK ENG Inc 16 Sept 1974 [23 Oct 1973] 40233/74 Heading G1A In an apparatus for measuring the mass and distribution of particles, e.g. viruses, in a sample 20 that may be treated chemically so that they fluoresce, the light emanating from the particles after they have been subjected to radiation from a laser source 22 is received by a photo-multiplier 30. The light reaching the photo-multiplier passes through a spatial filter 38, e.g. a lire screen, microscope type viewing optics 24 and a filter 26 which is restricted to the fluorescent wavelengths. The detector's output is passed via a D.C. filter 32 and a R.M.S. converter 34 to provide steady state signals representative of "T", the average total D.C. signal in the detector output, and "R", the root mean square value of the oscillations in the detector output. These signals are then processed as shown to supply two display devices representing the statistical particle distribution N=T<SP>2</SP>/(R<SP>2</SP>-T), or the mass M of the dye bound to each particle M = (R<SP>2</SP>-T)/KT. An alternative similiar digital signal processing system Fig. 2 (not shown), is disclosed.

Abstract: 1529456 Tensioning yarn running from a storage feeder WESCO INDUSTRIES CORP 10 Oct 1975 [15 Jan 1975] 41654/75 Heading D1J A yarn control device for controlling the feeding of yarn to a textile machine comprises a yarn storage member, means for causing yarn to be wound on the member adjacent one end, and guide means at the other end of the member defining two yarn withdrawal paths, the winding means having a portion which restrains yarn withdrawal to a preselected rate when the yarn is guided in one of the withdrawal paths, and which portion is clear of the yarn when guided in its other withdrawal path. When device 10, Fig. 2, is operated to release yarn Y on demand, the yarn wound by rotating member 20 on to stationary drum 16 is withdrawn over end of the drum and travels through and flexes a circular, outwardly extending array of resilient fingers 56 which oppose the yarn motion and tension it. The fingers, e.g. of nylon, wire or natural hair, are mounted by adhesive in grooves 54 in the bottom of ring 58, Fig. 4, and wholly support ring 42 by the free engagement of the finger ends, Fig. 1, in an inner annular seat of ring 42. The fingers are oriented in the direction of yarn withdrawal at an angle α which may be 45. End plate 40 is axially movable relative to plate 36 to adjust the tortuous yarn path to adjust yarn tension. Feeler 78 controls the yarn winder to maintain the drum windings within a predetermined range. To operate the feeder as a positive feeding device, where the yarn is wound and removed at the same speed, the yarn is withdrawn along the dotted line path of Fig. 2, the yarn engaging guide 27 on rotating member 20. Alternatively, Fig. 6, the fingers 104 supporting ring 92 each pass between one of the circular row of pins 100 on member 94, and rotation of ring 102 via plate 108 moves the fingers against the pins to alter the bend in the fingers and hence alter the resistance of the fingers to yarn movement.
