A tray assembly is provided which allows an information-carrying substrate to be seen through a cover portion thereof. The assembly includes a transparent cover mounted to an opaque base. The substrate is inserted between the cover and base which are then secured to each other. Openings are provided within the base to allow the cover to be detached therefrom. The cover and base include corresponding peripheral channel and ridge portions, respectively, which facilitate the mounting of the cover t...

A carton formed from a carton blank in which an end closure comprises at least three flaps hingedly connected to the carton front, back, and side walls, including the major flaps opposite one another and a minor flap having printing or other marking thereon for detachment as a coupon or for the commercial use. The minor flap carrying the printing or marking extends a substantial distance into the end closure opening.

Novel adhesives for preparing metal foil adhesive tapes meeting Underwriter Laboratories requirements for use with rigid fiberglass air ducts, which adhesive comprises a copolymer of: (1) at least one activated ester-containing vinyl monomer of Formula I (as defined hereinafter); (2) at least one ethylenically unsaturated carboxylic acid containing 3-5 carbon atoms; (3) at least one acrylic or methacrylic acid ester of a non-tertiary alcohol having 1-14 carbon atoms; and (4) at least one vinyl e...

A structure of alternating layers of titanium and an insulator or semiconductor material has temperature-sensitive electrical resistivity. In combination with a resistance-measuring circuit, such structure can serve as an accurate temperature sensor. And, since electrical resistivity is inversely related to temperature, disclosed structures can serve as miniature thermistors in integrated circuit devices.

The caliper system in a booklet collating system automatically measures a new zero position before measuring the thickness of a following booklet or booklets to eliminate a zero-offset error otherwise occuring from build-up of ink contaminants on the caliper rollers. The caliper rollers are preferably cylindrical and completely round. A reference roller projects into a window in a skirt of the conveyor. A measuring roller engages the reference roller through the window and is carried on one end ...

A die cushion construction for use in a press is the subject matter of the present invention. The instant die cushion construction includes a fixed plate connected to the press. A resilient cushion actuator has one end sealingly connected to the fixed plate. The resilient cushion actuator has an opposite end sealingly connected to a movable plate. The movable plate is adapted for connection to a portion of a die mounted in the press. A resilient snubber actuator has one end fixed relative to the...

A blower attachment for rotation with a filament line spool of a conventional filament line trimmer which attachment is provided with at least a pair of blades that are selectively extendable from the spool for providing a blower function.

An alternating current electrical circuit having a bank of capacitors connected therein and in which the voltage appearing on the circuit is varied by varying interconnection of capacitors and the possible appearance of resonance effects is controlled by interconnection of a resistor with the capacitors.

A counting device for use in a road toll charging or similar system has a number of escape members each driven by a long-life clockwork-type mechanism differently linked to a counter so that under the control of input means responsive to different signals radiated by roadside sources the counter is operated by a different amount corresponding to the particular input signal received. In particular whole units or fractions of units can be registered when a vehicle carrying the counting device uses...

Radiation-induced effects discovered in layered structures of conductor and semiconductor materials are utilized in radiation-sensitive devices such as, e.g., highly linear as well as highly nonlinear position sensors. Such devices includes a structure of alternating layers of conductor and semiconductor materials, and electrical contacts are provided between which a radiation-induced voltage appears. Among suitable layer materials are silicon and titanium, and resulting devices are sensitive to...
