Abstract: An elongated handle is provided having first and second ends and front and rear opposite longitudinal sides. Brush bristles are supported from and project outwardly from the front side of one of the ends and the other handle end includes a smooth endwise outwardly opening longitudinal bore formed therein. A piston is slidable in the bore and an operator is connected to the piston and rotatable on the other handle end. Rotation of the operator relative to the handle effects longitudinal displacement of the piston in the bore and the handle includes a supply passage therein communicated at one end with the inner end of the bore and opening outwardly through the front side of the handle between adjacent bristles at the other end. The bore equipped end of the handle is of greater cross-sectional area than the bristle equipped end and the front side of the handle includes a delineation zone thereof angulated relative to the longitudinal center axis of the handle between the opposite handle ends.

Abstract: A beverage brewing apparatus includes a hot water reservoir from which heated water is dispensed in predetermined serving volumes through a beverage filter to a serving beaker. A volume of cold water equal to a predetermined serving volume is admitted to a lower inlet zone of the reservoir, heated by an electric resistance heating element within the reservoir and dispensed in a volume equal to the serving volume from an upper outlet zone of the reservoir coincident with the introduction of cold water into the inlet zone. The reservoir has a volume greater than twice the predetermined serving volume so that a volume of resident heated water is contained in the central brew zone thereof. A temperature sensing element, e.g., thermistor, is disposed within the lumen of a hollow heat conductive tubing extending to a predetermined location in the brew zone at or near the center of the reservoir and produces a temperature control signal continuously indicative only of the temperature of the water in the brew zone.

Abstract: A flat top liquid carrying, paperboard container including four side panels, and inner and outer pairs of top closure panels alternately connected by respective horizontal score lines to the top edges of the four side panels as extensions thereof. While the inner pair of top closure panels each typically includes a substantially triangular panel portion and a pair of integrally connected fold-back panels, the outer pair consists of one shorter and one longer panel. A fold-over panel segment is formed on the end of the shorter panel. A diagonal opening-assist score line is formed on each of the shorter and longer panels, and a reverse diagonal opening-assist score line is formed on the fold-over panel segment extending from an end of the adjacent diagonal score line for lying on top of the latter when the fold-over panel segment is folded. A lift tab is formed on a side edge of the longer panel and extends past a portion of the edge of the adjacent fold-back panel.

Abstract: There is disclosed a flat end closure arrangement for a thermoplastic coated paperboard container, and the blank therefor, wherein four sets of dual, oppositely skewed, supplementary score lines are formed on two sides of the resultant end closure, such that they are adapted to be folded into position just inside the usual horizontal score lines separating the end closure panels from the sidewall panels. These supplementary score lines provide a second, substantially 90.degree. bend for the paperboard layers, supplementing a 90.degree. bend about the respective horizontal score lines, in lieu of each usual 180.degree. bend about the respective horizontal score lines, thereby diminishing the chances for cracking of the thermoplastic coating at the bend locations.

Abstract: The drawings and description disclose a thermoplastic coated square or rectangular cross-section container suitable for being filled with milk, juice or other still beverage, and having a top closure arrangement adapted to being readily partially opened to disclose an opening therein. The opening may be suitable for a straw or, alternatively, for drinking or pouring therefrom. The top closure arrangement includes edge panels on three sides thereof, with the front edge panel including straw opening means and having a central portion thereof adaptable to being folded back onto itself around a weakened or perforated line and having a lift tab extending therefrom, and a cover panel secured to the three edge panels such that the cover panel is peeled away from the front edge panel by manually lifting the lift tab. Alternately, in one embodiment, lifting the lift tab exposes a straw opening access to the contents, without disturbing the cover panel.

Abstract: A robot joint including a housing, dual inputs on opposite sides of the housing, an eccentric driven by each inputs and adapted to both planetate around an inner surface of the housing and to drive a first pair of bevel gears, a second pair of bevel gears, each of which meshes with both of the first pair of bevel gears, and a single cylindrical output member secured to one of the second pair of bevel gears. If the dual inputs and, hence, the first pair of bevel gears are driven in the same direction at the same speed, the cylindrical output member is caused to be raised or lowered, whereas if driven at the same speed in opposite directions, the output member is caused to rotate in a clockwise or counterclockwise direction. Variations in speed and direction will result in desired combinations of "pitch" and "roll" movements.

Abstract: A thermography machine applies thermography powder to the printed surfaces of sheets. Excess powder is vacuumed from the sheets under the influence of suction generated by a cyclone separator which separates the excess powder from an air stream in which the powder is entrained. A static charge eliminator is provided for neutralizing the electrical charge on the powder particles to facilitate a smooth flow of the particles through the separator. The static charge eliminator includes a plurality of electrical charged pins across which is conducted a flow of outside air which is sucked through the static charge eliminator by the suction pressure from the separator. As the air flows across the charged pins, oxygen is converted to ozone and the ozone is conducted into contact with the powder particles within the separator. The pins have a contoured profile along their length to maximize the ozone-producing process.

Abstract: An electromagnet is disposed between a pair of bearings rotatably mounting a spindle in the housing of a machine workhead, such as the workhead of a grinding machine. The magnetic flux from the electromagnet is guided by the spindle extending therethrough to its workpart driving end located outside the housing. Bearing shoes engaging the workpart are connected to the housing so as to complete the magnetic flux path to the electromagnet through the housing. Non-magnetic shields are disposed between the bearings and the electromagnet and housing to prevent wear debris accumulation and etching of the bearing components from magnetic flux effects.
