Title: Line signal monitor
IPC: H04M3/30
Filed: 1979-08-07
Abstract: In telephone systems it is often desirable to be able to monitor the conditions of the wires of the subscriber's lines served. One example of where this is needed is in a call data logger. In the arrangement described herein, for each wire to be monitored, of which each line has four, there is a high impedance detector. This detector has an operational amplifier OA to the input of which the wire to be monitored is connected as a high resistance potential divider R1-R2. The amplifier feeds a sample and hold circuit 3, to which is connected a storage capacitor 4. During a sample period, defined by a pulsed input, the output of the amplifier OA is sampled and stored on the capacitor 4. During the hold period the capacitor 4 is isolated from the amplifier OA and connected to a multiplexor plus analogue-digital connector 2, the latter carries a succession of digital outputs to be produced, one per wire to be monitored. Thus the wires to be monitored are sampled simultaneously and the results of the sampling read out successively. <IMAGE>

Title: Inspection of elongate articles for surface irregularities
IPC: H04N7/18
Filed: 1979-09-18
Abstract: Apparatus and method are described for inspecting elongate material such as strands, sheets, bundles or webs for the presence of surface irregularities. The material is illuminated for a short enough period to freeze the motion thereof leg with a stroboscopic light) and the illuminated scene is imaged on a television camera, and the video signal processed to obtain information about the irregularities. In the case of crimped fibres, regular variations should be present and can be counted within a given length, and angle of crimp can be measured. The stroboscopic light source 14 is used to illuminate the elongate material 10, preferably at an angle and to form light areas and shadowed areas depending on surface variations. A television camera 16 produces a video signal of the light and shadowed areas and such signal is electronically analysed with respect to number of alternating light and dark areas within a given length, and the relative widths of such light and dark areas, from which information can be obtained to confirm presence of irregularities, count or frequency of the irregularities, and, in the case of crimped fibres, the crimp angle. A filter can be used to improve the accuracy of the apparatus by removing low frequency signals, caused by unintentional shadowing, from the useful signals. <IMAGE>

Title: Meter
IPC: G01K3/00
Filed: 1979-12-17
Abstract: A meter for recording maximum and minimum values of a quantity over a period of time has an indicating pointer (1), a maximum recording pointer (4), and a minimum recording pointer (5), all three pointers being pivotable about a common axis over a graduated scale (3). The indicating pointer has a stepped portion which passes between the two recording pointers and engages one or other of them as it moves over the scale.

Title: Leak detecting of vacuum sealed packages
IPC: G01M3/36
Filed: 1980-10-06
Abstract: In the vacuum-packaging of foodstuffs in sealed thermoplastics envelopes, it is essential to ensure that no leaks occur and that the seal of the foodstuff within the package is satisfactory. Two types of leaks are known, that in which substantially no effective seal was created and thus a substantial volume of air is within the package and those in which pin holes, are formed which form "leaker" packages in which small quantities of air gradually enter into the package. This invention determines faulty sealed thermoplastics vacuum sealed packages by reducing pressure around the package and thus, allowing the package to expand due to the expansion of the remaining air within the package. The volumetric expansion of the package is determined by sensor(s) including electrical ones such as a condenser. Alternatively, and additionally, packages which have not been sealed at all will be more flexible than those which have been sealed and these may be determined by a bending test, a central part of the package being forced in one direction, relative to the opposite end parts. <IMAGE>

Title: Induction-Type Position Encoder
IPC: G01D5/247
Filed: 1981-03-04
Abstract: A magnetic induction-type position encoder and displacement detector contains two electrical windings 2, 3 and a bistable magnetic element 1, such as a Wiegand wire, which couples these two windings magnetically. One of the two windings, 3, serves as an exciter winding and is supplied with a periodic voltage signal which produces a periodically changing magnetic field. This field causes a periodic change in magnetic polarity of the bistable magnetic element 1. The periodic change in polarity induces in the second winding 2 a periodic train of electrical voltage pulses, the phase of which relative to the exciter signal can be influenced in relation to position by moving permanent magnets 6, 7 closer to or further away from the bistable magnetic element 1. <IMAGE>

IPC: H01K7/06
Filed: 1981-03-27
Abstract: A lamp bulb envelope, for creating a moire effect, has a plurality of transparent and nontransparent regions on its surface. When viewed from a point external to the envelope, the individual nontransparent regions on the surface of the envelope which is nearest to the point appear as superimposed upon and intersecting with nontransparent regions on the surface furthest from the point. The apparent intersections produce a moire effect which is enhanced by varying the line of sight to the bulb. The nontransparent regions may be either translucent or opaque and may be created by abrading the surface of the envelope or by application of opaque or diffusive coatings onto the surface of the envelope. <IMAGE>
