Abstract: A hand operated device for transferring an adhesive film from a carrier tape to a substrate is provided with a feed spool containing the carrier tape, and a take-up spool mounted in a housing. The carrier tape is fed from the feed spool to the take-up spool over an applicator bar and the take-up spool is driven by the feed spool through a clutch plate to maintain a degree of tension in the carrier tape during operation of the device.

Abstract: A hand operated device for transferring an adhesive film from a carrier tape to a substrate is provided with a single spool having a portion containing the roll of carrier tape and a large diameter portion having a plurality of knurls formed on the circumference thereof. The tape is fed from the spool to contact the substrate and then fed between the knurls. A spring arm serves as a clutch by maintaining the tape in contact with the knurls but allowing slippage of the tape therebetween at a predetermined tape tension.

Abstract: An interproximal brush for carrying on the person has an elongated one piece body member of elastomeric material forming a planar surface disposed between two leg members from which a substantially rigid boss extends for supporting a brush member. A plurality of hinges are formed in the body member at either side of the boss and the oppositely extending leg members are folded one adjacent the other and attached for slidable movement relative to one another. The planar surface is disposed transverse to the direction of relative movement of the leg members and rotates to move the brush from a position in alignment with the direction of movement of the leg members to a position forming an angle with the direction of movement of the leg members, when the leg members are moved relative to one another. The one piece body member may also be made foldable in the opposite direction to encase the brush within the leg members.

Abstract: A side (or heel seat and side) lasting machine comprises two lasting rollers (232; 232') arranged one at either side of a shoe support (20) by which a shoe is supported bottom up. Each roller (232; 232') has a helical rib arrangement (294) which, when rotated while in pressing engagement with the shoe bottom, effects an inwiping movement on the lasting marginal portions of the shoe upper. The rollers (232; 232') are inclined to the longitudinal center line of the shoe support, with their free ends directed heelwardly; the acute angle subtended between each center line and the roller axis of rotation is in the order of 50.degree. to 62.degree., preferably 57.degree.. The lasting rollers (232; 232') are of non-metallic material, preferably synthetic polymer or ceramic material, and have a single helical rib the pitch of which is in the range of 10 to 15 mm.

Abstract: A flat clip or staple is manufactured from a continuous strip of flat sheet material in coil form by first stamping out intermediate portions of material between each of the blanks to be formed into a discrete staple while retaining the blanks in the continuous strip. The strip is then subjected to a second stamping process where each discrete staple is severed from the strip, formed into the required shape and the excess waste material removed from the continuous strip. The second stamping process is located immediately adjacent the final stapling assembly operation, such that the staples never need to be transported to the final stapling operation site in separated form.

Abstract: For drying coatings of solvent-based adhesive applied to shoe bottoms a through-flow drying apparatus is provided which utilises air at ambient temperature for the constant rate period (i.e. the period during which the surface of the coating is "wet"), and thereafter applies infra-red heating during the falling rate period (i.e. the period when migration of the solvent through the solid adhesive is to be achieved). In the first stage, jets of air are directed against the shoe bottom at a velocity of not less than 15 meters/second (measured at the inlets (38)), while at the heating station a plate heater (42) of a size which is larger than the area of the shoe bottom is provided. Ideally, when the shoe is removed from the apparatus, an outsole having a reactivated coating of adhesive can be located with the shoe bottom and bonded thereto, without reactivation of the shoe bottom adhesive itself.

Abstract: A forming assembly comprises two presser members (22,24) each having a corrugated surface for receiving a workpiece made up of generally diamond-shaped pockets (10). Each presser member is made up of sections (22a,22b; 24a, 24b) mounted on slide rods (38) for movement between a spaced-apart position, in which a workpiece can be located therebetween, and a closed position, movement into which, while the workpiece is held between the presser members, is effective to compress the workpiece laterally. For holding the pockets in their diamond shape formers (20) are inserted therein. A flange (18) is formed at one end of the workpiece and integral therewith by pressing outwardly folded material against a lateral end face of the presser members (22,24) using a presser plate (52). This forming method is especially suitable for forming self-supporting filter units.

Abstract: A fluid dispenser for use with an elongated applicator having a container with a reservoir portion and a cylindrical neck portion, a tubular insert fabricated of softer material than the container disposed in the neck portion for receiving the elongated applicator and a rotatable cap which engages the insert when in the sealing position. A plurality of axially disposed vanes are provided on the internal surface of the cylindrical neck portion which serve to cold form the outer surface of the softer insert and become embedded in the insert to prevent rotation of the insert when the cap is removed.

Abstract: Apparatus for removing a marking from a stratum surface comprises a pellucid film in the form of a heat softenable polymeric material to be placed over a marking and a source of light energy for irradiating the marking and film to heat the marking and soften the polymeric material to thereby transfer the marking to the film. The apparatus in the form of a pen type implement provides means for energizing the light source and thereafter moving the pellucid film in single operation.

Abstract: A hand operated device for transferring a film from a carrier tape to a substrate is provided with a planar surface on its bottom wall, having a pair of laterally disposed flanges extending outwardly from the side walls, the side walls forming a hand gripping surface. An applicator bar over which a carrier tape is fed is spring biased downwardly to a point below the bottom planar surface, the point being such that the force required to raise the applicator bar to the plane of the planar surface is equal to the force required for laydown of the film onto the substrate. The device is operated by movement of the device over the substrate with said planar surface in contact with the substrate.

Abstract: A dispenser for depositing a liquid correction fluid onto a print medium is formed of an elongated tubular body having a valve means at one end and closed at the opposite end for retaining the fluid therein. The tubular body is substantially circular in cross-section at either end and comprises an enlarged body portion of larger cross-section for squeezing the material from the body when the valve is in the open position.

Abstract: A razor blade body in the form of a cartridge structure includes a guard member assembled thereon forward of, and extending parallel to, the blade or blades. The guard is of a two part molded structure having an upper portion of elastomeric material with a plurality of upwardly projecting protrusions formed thereon and a lower base portion of rigid plastic material having a downwardly projecting V-shaped cross-sectional portion. A pair of upwardly projecting elements are disposed in spaced relation forming a recess on the blade cartridge structure for receiving the V-shaped base portion therebetween and a latch means disposed in the recess retains the guard member in the assembled position.

Abstract: A rigid self-supporting filter unit is produced by placing two portions of fiber fabric in face-to-face contact and stitching them along parallel regions, using two rows of stitches (16), to form pockets into which formers (20) are inserted to shape the pockets into a generally diamond shape. This assembly is then placed between two presser members (22, 24) which are corrugated, the "valleys" of the corrugations receiving the diamond-shaped formed portions. The presser members are heated and the portions are thus treated by heat and pressure to cause the fabric to be rendered rigid. The formers can then be removed. Suitable fibers for this purpose include a rigidising fiber known as P84, polyphenylene sulphide fibers, polyester fibers either alone or mixed with polypropylene fibers, and bicomponent fibers.
