Title: Method and apparatus for gas analysis
IPC: G01N21/35
Filed: 1987-04-21
Abstract: Gas analysis apparatus comprises a radiation source (13) arranged to transmit radiation through a gas (12) to be analysed to a radiation sensor (32). Datum means (50-60) intercepts the radiation and transmits it to the sensor at a reference or datum value. The datum means comprises a mirror to reflect the radiation directly to the sensor thereby providing a zero absprption datum point. The datum means may also comprise one or more gas cells (54, 56,58) containing a high concentration of the gas to be analysed and thereby giving a high scale value datum point. The mirror and gas cells are mounted on a datum wheel (20) which is continuously rotated . Infra-red radiation from a source (13) is transmitted at two frequencies chosen for each gas to be analysed , by virtue of a rotary filter wheel 16 having pairs of filter discs (M1,R1) and (M2,R2) and (M3,R3).

IPC: B65D47/24
Filed: 1987-10-21
Abstract: The present invention relates to a threaded cap with 
limited opening intended to be used in containers for 
liquids over a wide range of viscosity.  
     The cap is characterised essentially in that it is made 
out of one piece only (1) that screws on a bottle neck 
(2) and has orifices (4) for the liquid to pass and 
inner (5) and outer (6) sealing rings, which provide a 
sealing effect. The cap also has a rib (8) that allows 
the cap (1) to be screwed to the bottle pack (2) and to 
be unscrewed only up to a limit formed by a protrusion 
(7) on the bottle neck (2). Sealing is achieved 
whenever the top of the bottle neck obstructs the 
orifices (4) and opening whenever the cap is unscrewed 
up to the limit, leaving the orifices properly cleared.  
     This new cap, made preferably from plastic material is 
a very simple part in respect to its production, it is 
difficult to remove without destroying it which makes 
refilling impossible, it allows the easy incorporation 
of a tamper-proof ring and, due to its rigidity, it 
also allows normal handling during transport and 
storage.

Title: Line tracer
IPC: G06F3/0488
Filed: 1988-06-06
Abstract: In a co-ordinate drive circular scanning pattern tracer, 
command marks give rise to pulses phase delayed 90° with re­
spect to the normal tracing pulses. In a system using a sinu­
soidal speed signal and sample and hold circuits to produce co-­
ordinate drive signals one sample and hold circuit compares the 
tracing pulses to the speed signal and the other sample and 
hold circuit compares 90° delayed tracing pulses to the speed 
signals. The 90° delayed tracing pulses are compared to the 
output pulses of the pattern tracer to detect the presence of 
the pulses produced by command marks. If such command marks 
a detected and command signal is produced which may be used 
to control the velocity of the system.

IPC: G01F23/00
Filed: 1988-06-13
Abstract: In a method of producing a printed circuit winding for a screened 
inductance sensor, a winding shape for a two-pole planar linear 
geometry is first of all computed. The shape of this winding is 
selected to provide an output in accordance with a specified transfer 
function for the sensor. The computed planar linear winding shape is 
then transformed to, typically, polar coordinates to provide a winding 
shape suitable for a rotary planar geometry. The method is carried out 
using a computer and the transformed winding shape is output to provide 
the printed circuit artwork. The method is especially suited to 
producing printed circuit windings for screened inductance level 
gauges, especially level gauges for fuel tanks where a physical barrier 
is interposed between the movable screen and the windings of the 
transducer. The method may also be applied to the design of concentric 
turn windings providing a similar output to that from an equivalent 
distributed winding in which the turns are displaced in the direction 
of relative screen and sense winding movement.

Title: Optical wavelength multiplexer/demultiplexer and demultiplexer/remultiplexer
IPC: G02B27/28
Filed: 1989-11-17
Abstract: A multichannel wavelength demultiplexer has two or 
more cascaded birefringent filter stages (45 and 47) for 
dividing an input signal (20) consisting of a plurality of 
adjacent channels of optical signals among a number of 
outputs, each of said filter stages (45 and 47) having a 
transmission function (83, 84, 85) with even symmetry 
about optical frequencies at the centers of both the 
longest and the shortest wavelength channels. This 
symmetry, common to all transmission functions, permits 
all birefringent filter stages (45 and 47) to be con­
structed from sequences of the same one size crystal 
element, thereby greatly lowering the cost of construction 
because solely one size crystal element is fabricated, 
tested and assembled. A multichannel multiplexer, 
identical to the above defined demultiplexer, but operated 
in reverse, is set forth. A combination multichannel 
wavelength demultiplexer/ remultiplexer consists of a 
single birefringent filter stage (45) for use in conjunc­
tion with multichannel multiplexer/demultiplexer to divide 
a common set of adjacent wavelength channels on its 
primary input between its primary and secondary outputs 
(51, 52) in any combination, and simultaneously to accept 
at its secondary input (25) different optical signals 
within the same wavelength channels as those exiting its 
secondary output (52) and recombine them to exit at its 
primary output (51), wherein said single filter stage has 
a transmission function (83-89) with even symmetry about 
optical frequencies at the centers of both the longest and 
the shortest wavelength channels. This symmetry, common 
 
 
to its transmission function and to those of said multi­
channel multiplexer/demultiplexer, permits all 
birefringent filter stages to be constructed also from 
sequences (54) of the same one size crystal element.
