The bottom roller cooperates with the drum surface and is electrically polarized to retain the toner on the transfer sheet.

Abstract: An accessory for use in pricking depth-indicating washers on to dental reamers comprises a body constituting a receptacle. The washers which are located in the receptacle are brought into a free space of the body within which they are juxtaposed. They successively engage a notch in a movable small plate, constituting a distributor element, which enables the washer located in the notch, by transverse sliding of the small plate, to be brought opposite to a hole of the body. The washer thus placed can easily be pricked by a dental canal reamer passing through a hole provided in the cover of the accessory and which is situated opposite to the hole of the body. The diameter of this hole is greater than that of the washers to allow the washer which is pricked on the spindle to be withdrawn from the receptacle.

Abstract: A separator plate for the negative electrode of a lead-acid battery comprising a molded, synthetic plastic wall or planar member of generally rectangular configuration. A pair of like separator plates are vertically oriented in the battery casing to sandwich the negative electrode therebetween including juxtaposed retention mats common in such a negative electrode assembly. The sandwich provides a clear-through channel along opposite extremities of the electrode for flow of electrolyte. The sandwich assembly is maintained by means of cooperating locking and sealing formations integral with the separator plates of the assembly. Wrapping of the positive electrode thereby is rendered unnecessary when assembling the battery and enables automated assembly of the battery using the separator plate sandwich.

Abstract: The incorporation of organic and FD&C pigments that meet FDA specifications for food packaging materials into resinous articles is accomplished by dispersing the pigments into a non-toxic mineral or vegetable oil formulation which contains glycerol monooleate and zinc stearate, the formulation then being added to the resin and mixed. Resinous articles colored in this manner can be utilized safely as direct food contact packaging, for example, decorative grass, which enables candies to be placed directly on the grass without incurring the expense of overwrapping the candies with a resin film which meets FDA and USDA requirements and which eliminates the hazard involved when candies are inadvertently or unknowingly placed on the decorative grass. The resinous materials which may be colored by the organic and FD&C pigments include polyolefin resins.

Abstract: An improved selector provides for air paths between a meter and an air volume sensing manifold that are similar for both up and down flow of air through the apparatus thereof. This provides similar momentum losses in the air reaching the meter for both air up and down flow through the apparatus to obtain more accurate meter readings of the air flow volume. Separate throttling screws are provided for the throttling orifices, providing different range selections, and are independently adjusted to compensate for minor air passage differences in the selector, and air flow pattern differences in up and down flow. A calibrated area reducer in the form of a sheet of perforated stock is positioned upstream in the throat in contact with the manifold to extend the measuring range of the apparatus while minimally disturbing the air flow patterns through the apparatus.
