Abstract: A coating applicator is provided having a plate cylinder including a cylindrical body about which a coating plate is mounted in sleeve-like fashion. The plate is the type used in the flexographic printing industry, and is made of photosensitive, monomeric material. The longitudinal edges of the plate are mounted to the cylindrical body using a clamping mechanism which permits easy installation and removal. Even with relatively light pressure, the photopolymer plate releases a substantial portion of the coating material when the plate is applied to a workpiece. Consequently, the composition and secondary rollers may be spaced apart by a gap slightly smaller than the thickness of the workpiece. Because of this gap, coating material does not tend to be applied from the plate cylinder to the secondary roller, thus reducing the safety and environmental problems associated with cleaning the secondary roller.

Abstract: A composite insert for a magazine or other publication is shown that includes a postal reply card. In one embodiment, the insert has a first portion formed of heavy paper stock suitable for use as a postcard, and a second portion formed of paper stock that is substantially lighter than the first portion. The first portion includes a perforated area defining a detachable postcard. The two portions are superimposed, and joined by a glued seam that is sandwiched between their respective edges. These joined edges are aligned together to define a unitary binding edge. This binding edge may be fed into a standard feeding unit of a perfect or other type binding machine as a single unit.

Abstract: A shielding blanket for racing engines includes a bag constructed of a lamination of materials including several plies of a high-strength ballistic textile material laminate having a high melting point. The blanket is shaped to fit closely over the cylinder block and oil pan of the engine, and between the block and the exhaust headers. Oil-absorbent pads are secured within the bag for capturing engine oil. Two of the pads face the sides of the cylinder block to prevent oil from escaping through either the engine block or the oil pan from reaching the exhaust headers.

Abstract: A device efficiently collects energy from a moving source without having to actively track the source. The device includes a primary concentrator, a secondary reflector and a target position. The primary concentrator is positioned to receive energy from the moving energy source and to direct the energy toward the secondary reflector. The secondary reflector has a concave surface which is covered by a number of convex reflecting surfaces. These convex reflecting surfaces direct the energy toward the target position regardless of the relative angle between the energy source and the primary concentrator.

Abstract: A device for generating ions in gas streams is proposed, which has an electrode arrangement exposed to the gas streams and a pulsed high voltage supply, which supplies an alternating sequence of negative and positive pulses with step edges. The electrode arrangement comprises at least one point discharge electrode and at least one counterelectrode associated with one another in fixed, clearly defined manner. The time behaviour of the high voltage signal is fixed in such a way that the duration of the particular pulse corresponds to the transit time of the ions between the electrodes and the spacing of the pulses is adapted to the speed of the gas streams.

Abstract: An apparatus for rapid colorimetry on different samples which has a transmitter for irradiating or through-radiating the particular sample and a receiver for receiving the radiation reflected or transmitted by the sample, as well as a filter arrangement. Also included is a computer for evaluating the signals from the receiver. The transmitter is formed by several semiconductor radiation sources, which irradiate in different spectral ranges and whose optical radiation is combined by means of a filter unit and is deflected onto the sample by a lens arrangement. A control unit controls the semiconductor radiation sources in successive pulsewise intervals. The control unit also supplies a signal permitting an association of the receiver signals to the radiation emitted in the different spectral ranges.

Abstract: A participartory device for producing artwork which includes a canvas or other suitable art medium mounted between a plurality of rotatable support posts which extend perpendicularly upward from a base. The rotation of one support post drives the canvas causing a lateral movement of the canvas. The device includes a drive mechanism which, in the preferred embodiment, is a bicycle-like apparatus permanently attached to the base. The rear or drive wheel of the bicycle-like device engages a plate member which extends radially outward from one support post so that pedaling the bicycle-like apparatus causes rotational movement of the support post and lateral movement of the canvas. The individual pedaling the bicycle-like device can apply paint or other drawing media to the moving canvas thereby creating a design on the canvas.

Abstract: The combination of a window covering and anti-flapping device for preventing flapping of the window covering against the window or window casing. The anti-flapping device comprises a U-shaped clip having a base and a pair of legs extending from the base. The clip is preferably fabricated from a flexible plastic material such that the inner surfaces of the clip legs are biased towards one another and are adapted to releasably engage the lower edge of a window covering, such as the lower edge or bottom hem portion of a window shade or baseboard of a venetian blind whereby the clip legs snap lockingly engage the window covering bottom edge. In one form of the invention the clip carries a resilient cushion contoured to be matingly received on the outer portion of one leg of the clip and retained there by means of a suitable adhesive. The clip is attached to the edge of the window covering such that the cushion is positioned between the clip and the window.
