Abstract: ABSTRACT OF THE DISCLOSURE      In a cross-folder for flexible pads such as diapers a wide first conveyor belt runs over a segment of the peri-phery of a rotationally driven drum.  A narrow second conveyor belt runs in parallelism with the first belt for transporting unfolded pads toward the drum and a third conveyor belt runs in parallelism with the first belt for transporting folded pads away from the drum.  The drum carries diametrically opposite pairs of slidable members that are reciprocated radially inwardly and outwardly as the drum rotates under the influence of cam rollers on the members which run in stationary cam grooves.  Pivotable levers are carried on the slidable members respectively. The levers have fingers for gripping the pads at their mid-line.  The levers have cam follower rollers which are forced to follow cam grooves carried by the drum and, under the influence of the slidable members, the levers are actuated to grip and release the pads to effect folding.

Abstract: Abstract:    For fermenting fermentable sugar solutions, yeast is added to the sugar solution.  The yeast sludge formed is separated from the mixture obtained and introduced into the reaction chamber.  Subsequently, after having completed the fermentation process, the yeast is discharged from the fermentation receptacle and, after having been combined with the nutrient solution, is at least partially recycled for producing the mixture with the sugar solution.  Prior to separating the yeast sludge, the sludge can be subjected to a flocculation step.  For improving the vitality of the yeast circulated along a closed circuit, the duration of the fermentation process is reduced by applying sub-atmospheric pressure for separating the alcohol by distil-lation during fermentation, thus equalizing the concen-tration of alcohol during the process.

Abstract: ABSTRACT OF THE DISCLOSURE   An optical data retrieval system featuring probe beams of different wavelengths directed onto an optically reflective recording medium having different spectral responses to the probe beams.  A first probe beam is directed onto the reflective medium in a manner such that the amount of light reflected from the medium may be detected while a second probe beam is directed through the medium in a manner such that the amount of light passing through the medium may be measured.  Different amounts for both beams are detected at pits in the medium and in the reflective field surrounding the pits.  The redundancy provided by two probe beams eliciting different spectral responses from the medium reduces errors due to dirt and media defects.

Abstract: TREATMENT OF CIGARETTE PAPER            Abstract of the Disclosure One version of a fire resistant cigarette comprises a charge of tobacco in a low-porosity wrapper substantially free of burn accelerator.  The sidestream smoke from this cigarette can be reduced by treating the wrapper with water or ethyl alcohol.  Fire resistance is further improved by depositing a linear burn rate reducing substance on the paper from the group consisting of citric acid, magnesium citrate, magnesium acetate, tartaric acid, acetic acid, lactic acid, a sugar, non-fat milk and skim milk.  Similar results are achieved with conventional medium to high porosity cigarette papers by treating them with a burn rate reducing substance from the same group.  In the case of high porosity cigarette paper, if only a part of the surface area is treated, the porosity of the untreated areas controls tar, nicotine, and carbon monoxide delivery.  Still further improvements in sidestream smoke reduction and fire resistance may be achieved by the use of an additional layer of high-porosity cigarette paper in the wrapper.

Abstract: ABSTRACT      An electric conductor suitable for use in an overhead electrical and optical transmission system comprises a layer or layers of helically wound wires, at least one elongate compartment within and extending throughout the length of the conductor and, loosely housed in the elongate compartment, at least one optical fibre ribbon structure comprising a plurality of optical fibres and flexible elongate reinforcing elements of resilient material arranged side by side and embedded in an elongate body of plastics material, each resilient reinforcing element being set in such a form that the ribbon structure follows a path of smoothly curved undulations whose axes of curvature lie parallel to one another and normal to the longitudinal axis of the ribbon structure.  If, when the conductor is installed or in service, the undulating ribbon structure is subjected to a tensile force, the ribbon structure will straighten in a lengthwise direction against the action of the undulating resilient reinforcing elements thereby reducing the tensile force otherwise applied to the optical fibres and, when the tensile force is removed, the ribbon structure will return towards its original undulating form.

Abstract: TITLE LIGHTING PANEL        INVENTOR Lorne A. Whitehead ABSTRACT OF THE DISCLOSURE The lighting panel has a first face for receiving light from a source and a second face.  The panel includes a first and a second sheet of transparent dielectric material.  Each sheet has a smooth surface on one side and is corrugated on the other side.  The surfaces forming the corrugations intersect at 90° the smooth surface on the first side is at 45° to the surfaces of the corrugations on the on the other side of each sheet.  The smooth surface of the first sheet forms the first face of the panel, the corrugated surface of the first sheet is adjacent to the smooth surface of the second sheet, with the direction of the corruga-tions on the second sheet set at a predetermined angle .alpha. to the direction of the corrugations on the first sheet.  Light thus enters the smooth surface of the first sheet and emerges from the corrugated surface of the second sheet.  The sheets may be substantially planar.  At least one of the sheets may also include light release mechanisms.  The angle .alpha. may be set at substantially 90°, or may be varied to produce a desired light directionality.
