Title: Process for applying a deformation to hair by using a roller and roller for the application of said process
Inventor: LEVEQUE JEAN-LUC
IPC: A45D2/24
Filed: 1992-04-27
Abstract: According to the process for applying reshaping to hair by use of a hair-curler, the hair-curler (1) is arranged in such a way that the perimeter along which the lock of hair (M) is rolled increases by approx. 2 to 3% when its temperature rises to pass from a starting temperature to a higher temperature which nevertheless remains lower than a relatively low limit thus avoiding the burning of the hair and/or of the scalp; the longitudinal section of the curler is sufficient to withstand the stresses imposed by elongation of the lock of hair; the lock of hair is rolled around the curler at the starting temperature so that the hair is retained against the hair-curler; the curler is raised to the said higher temperature; the hair is thus subjected to elongation ensuring an increase in the life of the reshaping applied to the hair.

Title: Absorbent members containing interparticle crosslinked aggregates
Inventor: ROE DONALD CARROLL
IPC: C08G18/60
Filed: 1991-03-25
Abstract: Absorbent members incorporating particulate, absorbent, polymeric compositions comprising interparticle crosslinked aggregates. The interparticle crosslinked aggregates comprise precursor particles of substantially water-insoluble, absorbent, hydrogel-forming, polymer material; and an interparticle crosslinking agent reacted with the polymer material of the precursor particles to form crosslink bonds between the precursor particles. The absorbent members of the present invention can comprise a combination of fiber material and discrete particles of the polymeric composition or laminates (layered absorbent members) containing such polymeric compositions. The performance of absorbent members is enhanced by the use of such polymeric compositions due to the high rate of fluid uptake and minimal gel blocking properties of the interparticle crosslinked aggregates.

Title: Lighted telephone dial
Inventor: DIAMANTIS PERRY W
IPC: H04M1/22
Filed: 1992-12-30
Abstract: A dial illuminating assembly allows for minimum power operation while maintaining uniformity of illumination in a telephone dial.  The dial illumination assembly includes a plurality of fiber optic light guides for receiving light rays emanating from a light source and for directing these light rays to aplurality of translucent buttons.  Illumination of the translucent buttons is achieved by creating multiple abraded surfaces on the light guides for dispersing the light rays in the vicinity of each translucent button.  The light guides are routed along opposed sides of the translucent buttons with abraded surfaces on the light guides beingpositioned next to each button for providing the desired illumination.  The dialilluminating assembly directs light rays so efficiently that only one light source is needed to provide uniform illumination in standard telephone dials.
Patent CA-2098516-A1 (CA)
Title: Pulp making device
Inventor: ALI SHAIKH F
IPC: D21B1/32
Filed: 1993-06-16
Abstract: The details of a device, being basically common for making high quality primarily mechanical, but also semi-mechanical and chemical pulps from almost all kinds of cellulosic raw materials such as wood, waste papers and non-wood plants - and with low capital and operating costs - are disclosed.      These raw materials, mainly due to the sloped configuration of the platform, butt against the retaining bars to maintain a relatively constant distance from the shower headers which are located behind these bars. These headers, through the shower jets, apply oscillating, fan-shaped, overlapping, hot water sprays under pressure, with or without chemicals, to the surface of the cellulosic material being defibered - to make pulp. The dislodged fibres i.e. the pulp passes through the floor-openings, to be collected and processed by the normal industry methods. As an example, to make a mechanical pulp from debarked logs, the pressurized, oscillating, hot jet water sprays, with or without chemicals, surround the wood fibres, soften the lignin, and dislodge the horizontally oriented wood fibres gently and in relatively less-damaged conditions. By using relatively low jet hot water pressure at a constant distance to a large amount of raw material at the same time, this basic-for-all-pulping device, with its low capital and operating costs, is an improvement on the existing art to manufacture uniform quality, strong pulps.
