Abstract: An automatic signal optimizing interface for connection between the antenna of an automobile radio receiver and the receiver itself processes the RF signal received by the antenna and provides an improved output signal to the automobile receiver which is optimized for distortion free reception. The output signal is limited to the desired frequency band to eliminate interfering signals, and is maintained within the optimum dynamic range of the receiver, even under reception conditions in which the received antenna signal itself is excessively high or undesirably low. The interface therefore permits superior performance by the radio receiver by optimizing the signal supplied to the radio and by preventing intermodulation distortion which otherwise commonly results from overloading of the front end of the radio receiver by excessively strong received signals.

Abstract: A convertible sofa and bed structure comprising a pair of pivotally interconnected frame members. One of the frame members is utilized as a backrest and the other as a seatrest in the seating or sofa position; and both are moveable to aligned horizontal positions in the bed position. An important feature of the structure resides in the fact that operating linkages are positioned outwardly of a zone beneath the frame member which functions as a seatrest. Thereby, the defined zone will provide an unobstructed storage compartment.

Abstract: A toothed power transmission belt comprising a body, transversely extending teeth positioned along at least one face of said body, and an inextensible tensile member embedded in said body, the material of said body comprising a blend of an epihalohydrin having a nominal Mooney viscosity of not more than 50 and an epihalohydrin having a nominal Mooney viscosity of not less than 50.

Abstract: An arm rest assembly for seating structures pivotally mounted on the upstanding sides of the back support for a seat and arranged for movement in an arc generally normal to the back from a retracted position in which its arm supporting surface is generally parallel to the back and extends toward the seat to a position in which the surface is generally perpendicular to the back and to a position in which the surface defines an acute angle with the back. A detent in the form of cooperating abutments on the pivotal elements providing the arcuate motion and resilient biasing means tending to displace the elements axially of each other enables the arm supporting surface to be latched in the perpendicular relation. In the parallel relation the arm rest element tends to conform to the seat back since it has a stiffening web depending from the arm supporting surface along its length on the side outward from the region occupied by a seat occupant to effectively wrap around the front and side portions of the seat back.

Abstract: In the manufacture of wood pulp for use in making paper and other wood fiber products, it is first necessary to remove the bark from the logs. While this can be done using a dry process, a wet process offers many advantages. However, one big disadvantage of the wet process has been the inability to economically remove the bark fines from the water used in the wet process. The present invention provides an economical manner of solving this problem by using a rotary vacuum precoat filter equipped with a rotating knife to remove the bark fines from at least a portion of the recirculating water in a wet debarking process and to avoid long range problems with such a process by adding a small amount of finely divided talc to the bark fines suspension prior to filtration.

Abstract: A toothed power transmission belt comprising a body with transversely extending teeth along at least one of its faces and an inextensible tensile member embedded in said body, said body being made from a chlorosulphonated polyethylene compounded with not more than 15 parts by weight of acid acceptor per 100 parts by weight of chlorosulphonated polyethylene.

Abstract: A portion of a clip fits into the cavity of a hollow core panel and another portion is attached to a structural wall. The portion inside the cavity has normally tapered opposed walls which are straightened, upon insertion into the cavity, to form parallel walls engaging the interior panel surfaces forming the cavity, thus providing a secure fit.
