Patent GB-2162635-A (GB)
Title: Shaft angle detection
Inventor: BURROWES DAVID W
IPC: G01D5/36
Filed: 1985-06-18
Abstract: Apparatus and method for non-contact determination of shaft angle utilizes a patterned disc 15 secured to the shaft or other rotor being observed. The disc has sectors 15A, 15B of different optical properties whereby radiant energy directed to the disc will be encoded by the sectored pattern. A set of detectors 22, provides variable output signals according to the amount of radiant energy received from the disc. These signals are converted to a set of digital signals which define a unique rotational position, and a computing means calculates angular position from these signals. The computing means will, if necessary, compare the digital output signals and then calculate angular position in a manner which is insensitive to small decenters (or lack of concentricity) in the arrangement of the shaft, disc, detectors, and any associated optical system. The radiant energy may be ambient, artificial lighting or modulated infrared. <IMAGE>

Title: Improvements relating to cigarette filters
Inventor: REYNOLDS MARTIN LANCE
IPC: A24D3/04
Filed: 1986-02-07
Abstract: A filter for a cigarette includes a porous filter rod circumscribed by a non-porous wrapper provided with at least one groove embedded into the periphery of the filter rod extending from the mouth end of the rod less than the entire length of the rod. Tipping material circumscribes the non-porous wrapper and is air pervious or is provided with flow-through openings therein in flow communication with the groove. The tipping material extends beyond the mouth end of the rod to define a recess, and the filter includes a cylindrical collar coaxially located in the recess concentrically with the portion of the tipping material extending beyond the filter rod mouth end. The thickness of the wall of the collar or the spacing thereof from the filter rod ensures that the groove mouth is not obturated. The collar functions as a baffle to accelerate the velocity of the air leaving the groove. <IMAGE>

Patent GB-2194626-A (GB)
Title: Crossflow heat exchanger
Inventor: TOUDOH YOSHINORI
IPC: F28F3/08
Filed: 1984-11-02
Abstract: A crossflow heat exchanger which is capable of being excellently used over a wide range from an exhaust gas high-temperature region to an exhaust gas low-temperature region below the acid dew point. In a conventional heat exchanger, such as a steel pipe type air preheater, when a gas including a large amount of a corrosive component is employed, it is necessary to prevent low-temperature corrosion and, therefore, it is not possible to lower the exhaust gas temperature below the acid dew point; consequently, this involves a disadvantageously low heat recovery rate for the heat exchanger. The crossflow heat exchanger according to the present invention employs a heat exchanger element of ceramics, which is free from low-temperature corrosion, whereby it is possible to lower the exhaust gas temperature and thereby to increase the heat recovery rate. The heat exchanger may be applied to a marine air preheater (particularly for a low-temperature portion), a gas heater for a desulfurizer and similar devices.

Title: Optical channel waveguides
Inventor: NOURSHARGH NOORALLAH
IPC: G02B6/136
Filed: 1986-10-15
Abstract: A film 1 of waveguide material is deposited on a substrate 2 of silica. A laser L is focussed on the film to produce local vapourisation. The substrate is moved relative to the laser to form grooves 3 and 4 so that the film material 1 between the grooves provides the channel waveguide. The relative laser and substrate position, laser scan speed and laser power are controlled by system 7,9,8. The waveguide material 1, may be germanium-doped silica and with this a CO2 laser would be used. It is also possible to form direction couplers with varying degrees of field overlap, see Figures 4 and 5. It may be desirable to add a cladding layer of lower refractive index material, see Figure 3. <IMAGE>

Title: Automatic door closer
Inventor: EVERS WILHELMUS HUBERTUS MICHA
IPC: E05F3/10
Filed: 1987-07-07
Abstract: A door closer in the form of a floor spring has two coaxial cams (4 and 5) (Fig. 1) fastened to its door spigot (3). One cam (4) acts via a roller (6) on the rod (7) of a restoring spring unit (8). The other cam (5) acts via a roller (9) and lever (10) on the rod (13) of a damper/assist unit (14). This unit (Fig 4) has a spring (25) which acts on a piston (24) arranged to drive oil through a hydraulic circuit (26) in which there is an automatic throttle (27). The shape of the second cam (5) is such that as soon as the door is "cracked" the force of the spring (25) in the damper/assist unit (14) acts to assist the door to open in opposition to the spring in the restoring unit (8). The throttle (27) is arranged to apply no significant damping to the movement of the piston (24) in this direction. However, when the door is released and closes under the force of the spring in the restoring unit (8) there is a reversal of the flow direction in the hydraulic circuit (26) as the rod (13) of damper/assist unit (14) is pushed in, and the throttle (27) is arranged to apply a significant damping action to the piston (24) in this direction. <IMAGE>

IPC: G06F17/15
Filed: 1988-02-09
Abstract: A sample sequence x(i) of length (M + K - 1) is correlated with a reference sequence h(i) of length M using a known correlator 1 of K-stages which may be for example a tapped delay line 5 and multiplier 7, to which sets of K reference coefficients are fed every K cycles. In a circuit arrangement, an adder 15 accumlates the successive outputs of the correlator 1 by virtue of a feedback link with a K cycle delay 17. Relatively long reference data sequences can be correlated with relatively long sample data sequences using a correlator having relatively few stages. The arrangement is equally applicable to convolution. <IMAGE>
