Patent GB-2272916-A (GB)
Title: Absorbent material
Inventor: KOLAR MILAN
IPC: A61F13/20
Filed: 1993-11-08
Abstract: A method for manufacturing an absorbent structure in an absorbent article, such as a sanitary napkin, tampon, panty protector, incontinence guard, diaper, bed protector, wound or sore dressing, saliva absorbent and like articles uses a dry-formed web of material comprising cellulose fibres, eg. roll pulp, directly in the product without first defibrating the material and then forming a mat The material possesses good wicking properties and swelling properties, high surface dryness, in addition to cellulose fibres, the absorbent structure may also include superabsorbent material and/or binding fibres or a binding agent, reinforcing fibres or a reinforcing layer. The pulp mat is very thin, therewith obviating the need to compress the mat further in the product. In the case of certain product applications, the material is softened mechanically prior to its use as an absorbent material. The article may have plural layers (14 - 16), one or several of which may be the material of the invention. Another embodiment has a single layer combined with a fluid permeable layer. A third embodiment is formed into a roll. <IMAGE>

Title: Howling remover having cascade-connected equalizers suppressing multiple noise peaks
Inventor: NAGATA YUICHI
IPC: G10K15/00
Filed: 1995-09-08
Abstract: A howling prevention apparatus prevents a howling noise which is generated in a sound amplification system using a microphone (27) and a loudspeaker (26). The howling prevention apparatus utilizes a plural number of first to n-th equalizers (311 - 31n), which have a variable frequency response and which modulate an output of the microphone. A detector detects a frequency point at which a loop gain of the system reaches a peak while supplying a standard noise signal (21) to the loudspeaker to produce a test sound and measuring the sound collected by the microphone through the series of the equalizers. A frequency response of the first equalizer is adjusted to suppress a noise peak at and around a frequency point detected by the detector. Then, a frequency response of the second equalizer is also adjusted to suppress a noise peak at and around another frequency point detected by the detector. Lastly, a frequency response of the n-th equalizer is adjusted by subsequently repeating the above setting procedure. <IMAGE>

Title: Laser cavity optical transducer
Inventor: WHITE IAN HUGH
IPC: G01D5/26
Filed: 1997-03-10
Abstract: An optical transducer for determining the change in optical length of a laser cavity, eg due to displacement of a mirror (3) by an external parameter such as force, comprises a laser diode (1) excited at constant current. The spectrum of the voltage signal across the laser diode is analysed and the spacing between the laser diode and the mirror 3 is determined from the formula f=(1+α)cm/2L where f is the frequency; c is the speed of light; m is the mode number, L is the effective optical length of the cavity, and α depends on the reflectivities of the laser facets. The laser beam may be conducted to a remote optical cavity of variable length by an optic fibre and the frequencies in the remote cavity measured. Temperature may be measured using a material which has a temperature dependent refractive index to vary the optical path length of the cavity.
Patent GB-2323450-A (GB)
Title: Optical modulator
Inventor: BOZEAT ROBERT JOHN
IPC: G02F1/025
Filed: 1997-03-20
Abstract: An optical device (20) comprises a multilayer structure incorporating in sequence a silicon dioxide layer (22), a n+ doped silicon buried contact layer (24) and a silicon surface layer (26). The surface layer (26) is selectively etched back to form an exposed rib (28). An upper surface of the rib (28) is doped to form an elongate p+ electrode (30) along it. The surface layer (26) is selectively etched to the buried contact layer (24) in regions remote from the rib (28) to form two via channels (32a, 32b) for making electrical connection to the layer (24). The rib (28) forms a waveguide along which radiation propagates. Charge carriers are injected from the electrode (30) and the layer (24) into the rib (28), including a central region (34) of it, when the electrode (30) is biased at a higher potential than the layer (24). The charge carriers induce refractive index changes in the central region (34) in which a major part of the radiation propagating along the rib (28) is confined.

Title: Laminated core for an electric machine
Inventor: RANDALL STEVEN PAUL
IPC: H02K1/24
Filed: 1997-06-12
Abstract: A core for a reluctance machine comprises a stack of laminations, each lamination 2,26 defining at least two pole faces. The laminations are each formed with a mounting hole 27 which is offset from the centre of the lamination. By mounting the laminations in progressively shifted rotational orientations about, hole 27 the pole faces of the core are castellated. This produces a smaller effective air gap in the assembled machine than the average actual air gap would otherwise create with a smooth pole face.
