Title: Vortex Shedding Flow Measuring Device
IPC: G01P5/01
Filed: 1981-01-07
Abstract: A body 2 generates Karman's vortices in a fluid flowing through pipe 1 and these cause the body to oscillate laterally, varying the capacitances between the wall of recess 21 in body 2 and electrode, 51, 52. The capacitances are differentially detected to measure flow rate.

Title: Processes for producing knitted, longitudinally elastic fabrics, and fabrics made thereby
IPC: D04B21/18
Filed: 1981-01-12
Abstract: The invention relates to a process for producing a knitted, longitudinally elastic fabric layer for use as an elastic or permanent elastic compression or support dressing and a knitted fabric layer produced by this process, whereby untreated elastic rubber or polyurethane threads undergo deformation during the knitting process. Each elastic thread is looped by an inelastic thread, accompanied by the formation of a fringe and longitudinally directed thin mesh members, which are interconnected by inelastic wefts to give a firm knitted fabric with no irreversible displacements of the mesh members in the transverse and longitudinal directions. As a result, a dressing with flattened edges is formed, so that there can be no pressurepoints or constrictions when applying the dressings. <IMAGE>

Title: Improvements in or relating to impedance matching devices
IPC: G01R27/04
Filed: 1981-05-21
Abstract: In the making of measurements at microwave frequencies, impedance matching is essential for meaningful results. Matching units have usually comprised a number of threaded tuning stubs working into a length of wave- guide, and matching has involved time consuming and skilled manual adjustment of the stubs for each frequency of operation. The invention provides an impedance matching device having in an energy transmission path (e.g. a wave guide 10) at least one adjustable member not having adjusting means to adjust said member, automatic drive means to drive said adjusting means, and signalling means to provide a signal related unequivocally to a variable state of the adjustable member. In one embodiment, each adjustable member is a tuning stub, driven by an electric motor which also drives a rotary potentiometer which can relay the position of the related tuning stub. The invention extends to an impedance matching system including a said matching device, a frequency meter, a programmable computer to actuate control means for controlling the said electric motors. <IMAGE>

Title: Optical apparatus for ascertaining eye accommodation state
IPC: A61B3/09
Filed: 1981-06-03
Abstract: Optometer apparatus for ascertaining the state of accommodation of an eye comprises a rotating radial grating (6) of helical form from which light from light source (3) is projected via e.g. a prism arrangement (10) with polarising beam splitter (11) towards the retina and returned light reflected from the retina forms an image of the grating in the vicinity of the actual grating. The prism arrangement (10) provides an extra reflection in the outward or return light path such that the grating image moves in the opposite direction to the grating. A detector (23) detects the modulation of returned light transmitted through the grating (6) which is at a maximum when the eye lens forms an image of the grating coincident with the reflecting layers of the retina. <IMAGE>

Title: An X-Y plotter
IPC: G01D9/40
Filed: 1981-10-14
Abstract: In an X-Y recorder for high speed plotting on a movable plain web i.e. a web without registration holes or other special means to maintain alignment of the web during plotting, repeatability of the plotting on the web by a transversely, movable pen as the web is moved back and forth is enhanced by a random rough surface drive wheel assembly which makes indentations along one surface of the driven edge of the web as it is first passed through the drive wheel assembly. Then as the web is reversed, these indentations substantially remesh with the random rough surface of the drive wheel assembly. The drive wheel assembly comprises a powered drive wheel with a rough driving surface against which an idler wheel is spring biased to form a pinch roller assembly through which the web is driven.

Abstract: A decoder for converting a linear p.c.m. input at a pulse density modulated (p.d.m.) sampling rate to a sigma-delta type p.d.m. binary stream, which can be demodulated by a simple R.C. filter, or otherwise, provides an analogue output as in a digital-to-analogue converter if required. The decoder basically comprises first and second recursive filters (F', G'), the output of the first (F') being applied to the input of the second (G'), which in turn outputs to digital comparator (13). Depending on the output of the comparator, a signal Q' has one of two values and is applied wholly or proportionally to the first recursive filter (F') and proportionally (as P') to the second recursive filter (G'). Each recursive filter comprises a respective multiplier (21, 22) and a respective storage register (11, 12) clocked at the same clock rate (fc), and with an input comprised by a respective adder (9, 10).
