Title: Liquid Flow-rate Measurement
IPC: G01F9/00
Filed: 1980-05-14
Abstract: The flow-rate of a liquid into or out of a container 1 such as an oil reservoir of an engine is measured by detecting the instants at which the surface of the liquid is detected at a predetermined series of fixed levels N1, N2,....Nn e.g. by a series of switches 7 actuated by a floating magnet 9, and the time between the surface passing adjacent predetermined levels is measured. The time value is divided into the value of the internal volume of the container 1 between the said two levels in order to give the required flow rate. <IMAGE>

Title: Apparatus for detecting the presence of surface irregularities in articles made of translucent material
IPC: G01N21/90
Filed: 1980-05-20
Abstract: The containers (5) are passed rotatably over a slit (7) having an opaque line (11) situated centrally about the longitudinal axis of the slit. A pair of light sources (15) are positioned beneath the slit and to either side of the opaque line (11) so that, in the absence of surface irregularities, light is refracted at an oblique angle through the container base. A diode-array camera (13) situated vertically above the slit and focussed thereon normally receives no light from the light sources. In the presence of a defect, diffraction of light occurs into the area of view of the camera causing a "defect present" signal to be produced which is processed electronically, enabling the defective container to be rejected.
