Abstract: A low pressure actuated labeling apparatus (10) for printing, cutting, and applying labels (L) to articles (A). A printing unit (12) prints information on a label, the label being drawn from a roll (13) of continuous label stock. A cutting unit (14) cuts a printed label from an end of the roll with the cut label being deposited on a tamper unit (16) which transports the label to a position (P2) adjacent the article and affixes the label to the article. Guides (26, 28) guide the label between the printing and cutting units. One of the guides (26) includes a plate (102) having spaced slots (106a-106c) in which are installed guides (108,110,112). The guides each include guide arms which are contacted by an adhesive side (Y) of the label. However, the guides are made of a material to which the label will not adhere, thus insuring continued movement of the label.

Abstract: A portable firefighting training system is provided that is useful in educating people as to proper firefighting procedures using self-contained supplies of fire extinguishing agents such as fire extinguishers and the like. Class A, B or C fires can be simulated through the use of a portable burner assembly and interchangeable mock-ups simulating burning structures.

Abstract: A cartridge housing is provided for a transfer roll and an abutting ink roll. The housing inner wall is spaced closely around the transfer roll with a discontinuity in an exterior side wall that is only sufficiently wide to permit less than 90 degrees of the transfer roll outer circumference to be exposed at any one time. The exposed portion of the transfer roll abuts a print surface on a print drum. A like discontinuity in the inner housing wall around the transfer roll at a point distal from the exterior wall discontinuity permits contact with an eccentrically mounted rotatable ink roll which supplies a continuous amount of ink to the transfer roll as the transfer roll turns.

Abstract: A line coder system includes an upright post mounted on a conveyor line and having an outstanding arm on which a rotatably mounted printing roller is mounted in association with a rotatable ink reservoir, the inward end of the arm being rotatably mounted on a shaft. A cross head mounted on the upper end of the shaft has a pin which engages the outer end of a spring assembly which tends to return the arm to a preselected position after it is moved by the containers which engage the printing roller.

Abstract: The invention provides a method and apparatus for treating articles with particulate material, for example for thermally toughening glass sheets. The particulate material consists of or contains permanently magnetized particles and is subjected to an electromagnetic field which travels linearly through the treatment space and is effective to sustain a dispersion of the particulate material in the treatment space. The article is contacted with that dispersion.

Abstract: A glass sheet is thermally treated, for example thermally toughened, by heating the glass sheet, and lowering the sheet into a gas-fluidized bed of particulate material which is at a glass-treatment temperature, for example quenching temperature. Extraction of gas from a localized upper region of the bed is commenced prior to the lowering of the hot glass sheet into the bed in order to produce gradually an unfluidized static packed condition of the material in that upper region of the bed. The glass sheet is lowered into the bed at a time after commencement of gas extraction which is such that the lower edge of the sheet passes through that upper region prior to full attainment of the static packed condition.

Abstract: A gas-fluidized bed of particulate material is operated by extracting gas from a localized region of the bed to produce an unfluidized static condition of the material in that region. The region may be in the upper part of the fluidized bed, or may be a region adjacent a side opening into the bed where the unfluidized static material obturates the opening. There may be a plurality of unfluidized static regions in the bed.The invention is applicable to the thermal toughening of glass quenched in the fluidized bed.

Abstract: An article, for example a glass sheet, is treated in a gas-fluidized particulate material by advancing the article along a path leading into the gas-fluidized particulate material and extracting gas from a region of the path at a rate sufficient to pack the particulate material in that region and thereby obturate the path. An opening leading into a container for a gas-fluidized bed of particulate material may be obturated in this way. The packed state of the material obturating the opening is such that an article can pass through the opening.
