Abstract: A spiked panel supporting member for supporting panels in a suspended ceiling, comprises a single elongated strip of material, preferably metal, in which there is provided outwardly extending spaced sharp spikes or prongs 3, preferably triangular in shape, with the remaining blank portion of the strip providing a longitudinally extending planar flange 2. When the member is brought into abutting relationship along the lateral edge of a panel the spikes or prongs 3 are caused to penetrate the material of which the panel is formed the blank flange 2 providing a means of supporting the panel by engagement with co-operating panel support members. The blank flange 2 may be folded around the longitudinal axis to form an upwardly extending flange at right angles to the spikes, the said flange having a longitudinally extending rib at or near the top free edge so as to provide a shoulder or seat for security of mounting when in engagement with associated support member having a spring like action. Such a member having a vertical flange at right angles to the said spikes or prongs 3 wherein may have a downward slanting tongue projecting outwards from the back of the flange to provide a means of replacing a panel within a constructed ceiling, the free end of the tongue engaging the bearing surface of the panel supporting flange of a co- operating member supporting the ceiling panels. <IMAGE>

Title: Determining absolute value and polarity of electrical parameters
IPC: G01R19/14
Filed: 1979-07-25
Abstract: The absolute value of an electrical parameter is derived by rectification 15 of a proportional current Im and is displayed on a meter 17, while the polarity of the parameter is derived and separately displayed 26 on the meter panel by injecting into the signal path a polarity-representing signal Ia, the presence of which is subsequently detected. An oscillator 19 of relatively high frequency injects a signal Va into the input 4 of an operational amplifier 10 whenever an FET 18 is turned on by a signal Vi of appropriate polarity. The output current Ia arising from the injected signal actuates LEDs 26 but is blocked 28 from the rectifying bridge 15, whereas the current Im to be measured is blocked from the LEDs 26 by a capacitor 27. The presence of a Zener diode 16 downstream of the bridge 15 produces a step in the voltage output of the amplifier 10 at the zero crossings to assist the switching of FET 18. <IMAGE>

Title: Digital storage and processing of picture signals
IPC: H04N1/64
Filed: 1980-03-04

Patent GB-2073426-A (GB)
Title: Apparatus for measuring the speed of flow of an ionizable gaseous fluid
IPC: G01P5/00
Filed: 1981-02-27
Abstract: Ionizable gas flows at speed V1 at right-angles to the axis of a cylindrical, aerodynamic obstacle 5, and downstream two rows of vortices result. The vortices T1, T3 in one row being staggered substantially equally relatively to the vortices T2, T4 in the other row. The frequency at which the vortices pass a given point is a function of the speed V1. Parallel with obstacle 5 is a wire 1 maintained at high potential ionizing the gas by corona discharge to produce ion currents to parallel cylindrical conductors 3 and 4 equispaced from wire 1 and in the same plane at right angles to the gas flow. The passage of the vortices varies the ion currents. The current outputs for conductors 3, 4 are fed to respective operational amplifiers whose outputs go to a differential amplifier providing an output S1 alternating at the frequency of the passage of the vortices passed conductors 3, 4. The alternating output is coupled via a capacitor to a high gain comparator amplifier 15 supplying an AND-gate connected to a clock. The square-waves from the gate at the frequency of S1 are counted by a digital counter over a given period to provide a measure of the speed V1. Speed components at right angles may be measured using a second pair of conductors, each pair providing vortices for the other pair. <IMAGE>

Title: Detergent composition for washing fabrics
Inventor: HOLLINGSWORTH MICHAEL WILLIAM
IPC: C11D3/37
Filed: 1982-10-20
Abstract: Fabrics can be washed with a wash liquor to which has been added a detergent active material, a water-soluble carbonate material such as sodium carbonate and a carboxylic polymer such as hydrolysed polymaleic anhydride or a hydrolysed copolymer of maleic anhydride, ethyl acrylate and vinyl acetate. The polymer reduces the level of inorganic deposition on the fabrics provided that the initial calcium/ carbonate saturation ratio in the liquor is below about 50. Thus the method is particularly suitable for use with water having a hardness below 20 DEG  FH, at product dosages below 5 g/l, and/or at temperatures below 60 DEG C. The saturation ratio may also be reduced by including a calcium sequestrant such as NTA in the composition.
