Abstract: ABSTRACT OF THE DISCLOSURE         As textile fabric is spread from a roll onto a cutting table in stacked layers, the cutting pattern is selectively projected by the apparatus of the invention onto the unrolled fabric wherever a fabric flaw is known to exist to enable the operator to determine, prior to attaching a corresponding paper pattern to the spread fabric, whether or not the flaw will otherwise be present in an area to be cut out according to the pattern.  A film of a reduced scale image of the pattern to be cut out is provided together with a projector for projecting portions of the film pattern onto selected portions of the fabric.  An x-y carriage mounting for the projector enables the projector to be movable over the length and width of the fabric spread on the planar surface.  Film indexing means selectively advance the film lengthwise through the projector in correspondence with the projector's position along the length of spread fabric.  A gear and slide assembly interconnects the film and projector relative to the x-y carriage so that as the projector and film are moved across the width of the fabric in one direction and at a first velocity the gear assembly moves the projector relative to the film in the opposite direction and at a second velocity which has the same ratio to the first velocity as the scale of the film image pattern has to the actual size pattern; with the resulting effect being that the portions of the pattern on the film which are projected onto the fabric appear to the operator to have a fixed position relative to the fabric.

Abstract: ABSTRACT A slurry of cellulosic fiber and water having a consistency in the range of 0.017-4.99% of the total ungassed weight of fiber and water is bleached with ozone. This is done without the usual addition of organic additives. The water can include impurities created by the bleaching process. Rapid reaction times under 3 minutes and preferably under 5 minutes are achieved. The reaction is enhanced in the consistency range of about 0.0017-0.7% The slurry is mixed using a mixing energyof 0.002-1.0 horsepower per cubic foot of gassed slurry. The mixing energy will determine whether the gas-liquid or liquid-solid interface will limit the speed of the reactions. The passage of ozone from the gas to a liquid phase will be the limiting factor below about 0.2 horsepower per cubic foot of gassed slurry. The increasing presence of ozone in the liquid as the horsepower increases from about 0.2 to about 0.4 horsepower per cubic foot of gassed slurry indicates this is a zone in which both the gas-liquid and the liquid-solid interface are limiting factors. Above about 0.4 horsepower per cubic foot of gassed slurry the liquid-solid interface will be the limiting factor. Superficial velocity of the ozone bearing gas is in a range of 200-3800 feet per hour. The ozone usually is 0.05-6% by weight of the total weight of the gas.

Abstract: ABSTRACT OF THE DISCLOSURE         A structurally strong heat insulator is depicted in the backing plate and pressure plate regions of an aircraft multiple disc brake assembly.  The insulator is constructed from a plurality of perforated metal sheets in order to withstand the large compressive forces experienced during a brake application.  The sheets are com-piled randomly into an insulating stack which thereby offsets the holes in adjacent sheets.  The holes decrease the surface area and the offset increases the heat conduction path, both which reduce the amount of heat conducted through the stack.

Abstract: ABSTRACT OF THE DISCLOSURE    Tobacco smoke filters and methods and means for making same wherein the products have an elongated annular intermediate member overwrapped with a conventional plug wrap, with discrete inner plugs of a length shorter than the intermediate member and offering at least as much resistance to passage of smoke as the intermediate member, being secured within the intermediate member against axial displacement. The inner member may be formed of a filtra-tion material, as is the intermediate member, or the inner member may be formed of a material which is non-permiable to smoke.  Portions of the intermediate member may be crimped to embed them into the inner member thereby im-proving the engagement between these members.  The inner member may be centrally positioned within the intermediate member to form cavities at each end of the filter or, alternatively, the inner member may be secured at one and of the intermediate member to provide only a single inner cavity.  The smooth outer surface of the intermediate member enables the attachment of a conventional plug wrap without the need for an internal glue line.  Means are dis-closed for cutting an inner rod to form a multiplicity of inner plug members, and then axially spacing the inner members from each other by injecting jets of air or the like between adjacent inner members.

Abstract: ABSTRACT OF THE DISCLOSURE           As described herein, there is provided safety apparatus for continuous rotary blow molding machines of the type wherein the extruder operates independently of the machine to continuously extrude plastic tube through its die head during the interruption of operation by the blow molding machine.  The safety apparatus includes a blow tube mounted on the extruder for directing air under pressure against the plastic tube to deflect the tube away from the molds of the molding machine upon interruption of the operation of the blow molding machine.  A conveyor, operative at the same time as the blow tube and extending in a direction coincident with the direction of pressurized air, receives the diverted plastic tube and carries the plastic tube to a receptacle.  The blow tube and conveyor remain operative at least until the machine is restarted.  In order to permit the plastic tube to resume its normal direction of discharge into the molds, there is also provided a cutting device for cutting the plastic tube right at the die head of the extruder a predetermined time after the machine is restarted.          Finally, a safety gate, providing access to the molds of the machine when open, includes safety switches which disable the machine when the gate is open.
