Title: Monitoring hydrocarbons in air
Inventor: RATFISCH WERNER
IPC: G01N33/00
Filed: 1983-06-14
Abstract: In a process for monitoring total hydrocarbons and also the concentrations of the individual hydrocarbon components in a gas or vapour mixture, for example in air, total hydrocarbon concentration is measured by a flame-ionisation detector, a portion of the mixture is passed through a chromatographic column, which separates the components from each other and the separated components are fed in succession to a flame-ionisation detector, which measures their respective concentrations. The apparatus thus measures continuously both total hydrocarbon concentration and the concentrations of the individual components. If total hydrocarbon concentration, or if the concentration of any component, exceeds the specified safe value, the plant is automatically shut down.

Title: Sensing changes in the filtering effects of gaseous filters
Inventor: NEDERMAN BILL PETER PHILIP
IPC: B03C3/66
Filed: 1983-09-21
Abstract: In a method and device for sensing changes in the filtering effect of electrostatic filtering devices (2) for separation of contaminants from gaseous streams, changes in voltage between filtering means (5) of the filtering device (2) are sensed, and signals are emitted (at 8) when a certain change in voltage takes place. The resonance voltage from filter cells (5) of the filtering device (2) are applied to a plurality of comparators (Figure 3) (not shown) set at different threshold levels. The outputs of the comparators control a pulse circuit which feeds means for emitting light, sound and control signals in dependance on changes in voltage between two filter cells (5). <IMAGE>

Patent GB-2157836-A (GB)
Title: Attenuation measurement
Inventor: SATCHELL RODNEY JAMES
IPC: G01R27/28
Filed: 1984-04-17
Abstract: A method is disclosed of measuring the attenuation, by an electrical component or unit 8, of radio frequency (RF) signals. The method is a modification of that disclosed in British Patent Specification No: 1,576,104 wherein an RF carrier wave is passed through an attenuating component, this carrier wave is pulsed, and there is compared the values of a chosen pulse characteristic for a given carrier wave power level with and without the component under test in the circuit. Unfortunately, this suffers from the drawback that any drift in the RF carrier wave signal level during measurements will impair the results obtained. In the present method, a carrier wave signal from source 1 is fed to a single power level reading means 13 via one or other of two channels - one the Test channel (containing the attenuating component 8 under test) and the other the Reference channel (more or less directly), there being carrier wave modulating means 5T, 5R in each channel, and one or other channel being selected as required to provide either a Test Signal or a Reference Signal. <IMAGE>

Title: Optical measurement of human feet
Inventor: FEAVER JOHN LIONEL
IPC: G01B11/02
Filed: 1984-05-25
Abstract: Apparatus for measuring the dimensions of a foot for shoe fitting purposes comprises a trough into which the foot is placed with arrays of light-emitters and receptors in the side-walls. The length of the foot is derived from determining where the toe and heel obstruct light beams across the trough between the arrays. A time-division multiplex system is used to give effective collimation of the light beams and so allow close packing of the emitters and receptors without interference between adjacent members of the arrays. Width and height of the foot are also measured. <IMAGE>

Title: Artificial grass sports surface
Inventor: HAWKINS PAUL
IPC: E01C13/08
Filed: 1985-10-02
Abstract: To apply an elongate strip of fill-in material to a synthetic pile carpet adapted to simulate a grass playing surface the height of the pile in an elongate path in the carpet surface is reduced (e.g. cut or melted) to form a channel in said pile and a strip of the fill-in material is inserted substantially to occupy the channel and restore the original overall height of the pile. Conveniently, the fill-in material is a strip of pile fabric of a colour which contrasts with the carpet and forms a demarcation line. Alternatively the channel may be formed along a join in the carpet and the strip is of the same colour to mask the join. <IMAGE>

Title: A mounting for a push button
Inventor: MEECH GEORGE THOMAS
IPC: H01H13/14
Filed: 1989-01-19
Abstract: A mounting for a push button comprises a face plate (2) of stainless steel through which a stepped aperture (4) extends. A cylindrical support body (12), also of stainless steel, extends through the aperture (4), a flange (16) of the support body (12) abutting a support surface (10) of the face plate (2) defined by the aperture (4) such that the outer surface (18) of the support body (12) is substantially flush with the outer surface (6) of the face plate. A switch housing part (28) engages the support body (12) to hold it relative to the face plate. An axially reciprocable push button (40) extends in a bore (14) of the support body (12) which determines the limits of travel of the push button. The outer surface of the push button (40) does not protrude relative to the outer surface (6) of the face plate (2). The construction renders flush the elements of the push button switch which are accessible to the public, and thereby the push button switch is proof against vandalism. <IMAGE>
