摘要:
A roll fed labelling system and associated label are disclosed. The label (12) includes a triggering mark (28) formed of luminophor ink, i.e. containing a fluorescent optical brightening agent, that reflects as visible light directed UV light. A modulated UV light is directed at the label and the modulated reflected visible light is detected and used to trigger a cutting mechanism to separate a single label from the remainder of the roll. The triggering mark need not visibly contrast with the surrounding graphics of the label and may be invisible in visible light. When producing the roll of labels, the amount of brightening agent may be controlled by monitoring the luminescence of the triggering mark relative to a reference level which may be derived with reference to a miximum luminescence of other parts of the label.

A cutting/crushing device for the demolition of buildings has a pair of jaws (1) that pivot on frame (2). The jaws (1) are constrained to pivot in synchrony because each jaw (1) remains engaged with a guide pin (12) which substantially prevents relative movement of the two jaws (1). The guide pin (12) is guided by a slot (13) in the frame (2), aligned with a plane of symmetry between the two jaws (1), to prevent it from moving toward or away from either jaw (1). By guiding the guide pin (12) in this way, frictional binding and wear of the guide pin (12) are minimized. In addition, the shape of the recesses (11) into which the guide pin (12) fits can have smaller tolerances reducing play between the two jaws (1). Stoppers on the frame press against the rotatable jaws when they are fully opened to prevent any play.

A radiating pipe disposed in a floor for heating the floor includes an outer pipe (12) and an inner pipe (11), a heating cable (2) passing through the inner pipe (11) and the space between the inner pipe (11) and the outer pipe (12) being an empty air space. Optionally, materials such as sand, rock particles, a mixture or sand and rock particles, and concrete can be sealed in the empty air space. The inner pipe (11) and the outer pipe (12) can or at least one such pipe can be a copper pipe and the two pipes can be formed as an integral structure.

A hollow shaft of a screw conveyor for transporting powder material receives pressurized air in its interior. A plurality of openings through the wall of the hollow shaft permits the pressurized air to exit energetically to prevent build-up of the powder material on the inside wall of the casing of the screw conveyor. In one embodiment, the openings are slits angled with respect to the axis of the screw conveyor at about the same angle as the helical blade. This produces a swirling flow of air which, in addition to preventing build-up of materials, enhances the advance of the powder material and, when the powder material is a mixture of different materials, helps prevent separation of the materials during transport.

A fully automated system for the work of fee payment in supermarkets and other distribution outlets has a conveyance means 1 that conveys products 8 to be purchased, a reading means 2 that reads box codes printed on the products, a recognition means 3 that specifies the product names, quantities, and prices by the image read, referring to the read box codes by a merchandise control table 4, a computation means 5 that totals up the specified products and calculates the price to be paid, a display means 7 that displays the calculated monetary amount to be paid, and an exact-calculation means 6 that carries out the exact-calculation procedure by cash payment or a box-code prepaid card 10 according to the displayed price to be paid.
摘要:
Disclosed is a roll closure for packaging sacks or the like, comprising an extension (1) of the body of the sack which can be rolled up and a reinforcement for the extension when rolled up; at least two strips (2) of a flexible material are provided in the vicinity of the extension and parallel to the end of it on both the inner and outer sides, are substantially congruent with one another when the extension is laid flat or partially or totally rolled up and protrude laterally beyond the extension.
摘要:
A large-scale cleaning vehicle (75), for operation with a forklift (9), includes rotation brushes (14) for sweeping debris toward a center of said cleaning vehicle (7-5), a sweeping brush (17) for sweeping the debris into a debris collection box (15) and a fan (34) for pulling said debris into said debris collection box (15) without the need for a motor in the cleaning vehicle. Each of the rotation brushes (14), the sweeping bruch (17), and the fan (34) are rotatably connected to a rear wheel (18) of the cleaning vehicle such that when the cleaning vehicle is moved, the brushes and fan are rotated. The cleaning vehicle further includes a vertical adjustment for the rotation brushes (14) to lift them when they are not needed, a lateral adjustment for the rotation brushes (14) to adjust a width of sweeping, an audible warning (91) for pedestrians, a water sprinkler system (83) to aid in the cleaning process, and a large-scale trash removal brush (74) mounted in front of the cleaning vehicle to push large-scale trash.
