Abstract:
A towel dispenser includes: a housing for receiving toweling; a motor assembly that causes a leading edge of the toweling to be extended from the housing such that a line of perforations in the toweling along which a user tears the toweling is located downstream of the sensor, and the toweling to be retracted into the housing after the leading edge has been extended; and a sensor that senses a leading edge of the toweling during retraction of the toweling. The sensor causes the motor assembly to cease retracting the toweling into the housing as a function of the sensing of the leading edge of the toweling. The toweling may be a roll of perforated paper towels.

Abstract:
A method of opening an ampoule and an ampoule opening device are disclosed. The method in at least one of the embodiments includes providing a structure that includes an elongated housing having a longitudinal housing axis and an inner cavity, an open housing end, a closed housing end, sidewalls disposed between the open housing end and the closed housing end, the sidewalls having an outer housing surface and an inner housing surface forming at least a portion of the inner cavity; and a lid or rotatably flexibly secured to the elongated housing proximate the open housing end; positioning the upper tip portion of the ampoule in the elongated housing such that the upper tip portion is substantially enclosed within the inner cavity of the housing, the lower liquid portion is substantially outside the housing and the longitudinal ampoule axis is substantially parallel to the longitudinal housing axis; pressing the lid against the longitudinal outer surface of the lower liquid portion of the ampoule with a thumb or finger; bending the elongated housing with respect to the ampoule such that the longitudinal housing axis rotates with respect to the longitudinal ampoule axis and the neck portion of the ampoule breaks; and separating the longitudinal outer surface of the lower liquid portion of the ampoule from the lid, after which the lower liquid portion can be secured and the housing containing the upper tip portion of the ampoule disposed of.
Abstract:
A lazy-susan type roll table supports, in a vertical position, a roll of place mats interconnected into a continuous web (i.e. each mat is attached to its adjacent mat by perforations and all are rolled up on a core to form the roll of material). A web feed roller, also disposed for rotation about a vertical axis, is spaced from the roll table and cooperates with a pinch roller to grip therebetween the web of place mats and to feed the place mats along a path. An end panel positioning plate receives the end place mat, as the web is being fed, and carries an infra-red sensor which responds to the presence of the perforations between the mats to terminate drive of the web feed roller. A web tension drive extends up through the core of the roll of place mats and mounts a soft rubber drive wheel which when driven urges the web roll in a direction opposite to that imparted to the web by the web feed roller. Control circuitry actuates the tension drive when web feed drive terminates to apply tension to the web and facilitate severing of the end place mat, from the other place mats, along the perforations when the end place mat is positioned at the end panel. The end panel also carries a micro-switch which senses the absence of the just separated end place mat to terminate power to the tension drive and start web feed drive to repeat the process of positioning a place mat at the end panel. A jogging switch is provided to facilitate short web advancing operations of the web feed and an oscillator is provided to adjust the length of advance of the web to thereby compensate for different size place mats.
Abstract:
A dispenser for carrying bags from a roll-wound or layer-packed continuous strip form supply, presenting ready for the user a single bag pendent from a mouth device, which is shiftable upon tearing off a bag to initiate automatic feed of a bag length of the strip by strip embracing drive rollers. With bags having grip holes, feed rollers cooperating also as normally closed switch contacts, in sensing arrival of a hole, determine the feed of a bag length for terminating a feed cycle. Small front space is required by the mouth device in store display areas.
Abstract:
Heat-severable film-dispensing apparatus which is located underneath a surface on which items are wrapped in the film and which includes rollers for supporting a replaceable film supply roll and a switching mechanism coupled with the film to cause a film-severing wire to be heated when the film is laid out across the wrapping surface. The apparatus also includes a brake for preventing the feed-off of film and a control device for raising a wire guard which are operated in response to the actuation of a switch bar so that the film can be severed by the heated wire.
