Abstract: ABSTRACT OF THE DISCLOSURE        This invention comprises a suitably colored liquid composition which can be applied to wet or frozen lumber to provide identification marks or water repellent seals to the end grain so that such marks and seals are not removed by exposure to heavy rainfall.  The composition can also be applied to wet or frozen logs or trees over bark or slimy wood to provide adherent marks which are not removed by heavy rainfall or immersion in water.  Prior log marking paints or lumber end sealers can not be applied to wet or frozen wood or bark without being removed by subsequent rainfall.  Plastic tags are difficult to apply and arc easily knocked off during handling of the logs. They are attractive to crows and sea-gulls and are frequently removed by such birds.

Abstract: HATCH COVER             ABSTRACT OF THE DISCLOSURE    A hatch cover for closing and sealing a hatch open-ing has radial latching arms connected at their inner ends to a rotatable arm-actuating hub on the bottom side of the cover at ball-and-socket connections and loosely connected to the cover near their outer ends,  In one rotational position of the hub the arms overlap and apply clamping pressure to the rim of the hatch opening and in a second rotational position of the hub the arm-clamping pressure is released and the arms are retracted from the rim to enable removal of the cover from the opening.  The hub rides on camming surfaces of the cover which are shaped so that as the hub rotates in a hatch-closing direction, the arms first extend over the rim of the opening and then pivot into clamping engagement with the rim about their loose connections to the cover, urging the cover through such connections into tight seated engagement with the rim,  A resilient sealing ring with double lips and car-ried by the cover engages the rim when the cover is seated to seal the hatch opening.  A shaft extending through the cover and axially slidable and rotatable relative to it and the hub can be selectively engaged with the hub to rotate it.  A handle fixed to the upper end of the shaft is used to engage and disengage the shaft and hub and to rotate the hub to acti-vate the arms,  The top surface of the cover is recessed to receive and store the handle flush with the cover surface when not in use.

Abstract: AIR CUSHION VEHICLE            ABSTRACT OF THE DISCLOSURE       A vehicle, primarily a marine vessel, but also adaptable for travel over snow or ice, which is supported and propelled by air flow through a channel in the underside of the body. An impeller in a duct in the forward end of the vehicle provides the air flow, which can be deflected rearwardly, downwardly and forwardly and varied laterally for full control of the vehicle. The air flow channel is divided into a central channel and high speed side channels by longitudinal curtains, the side channels conducting air to steering vanes and rudders at the rear of the body. Trim rudders also extend across the rear of the channel to control lift and roll at the rear of the vehicle. In one form, the vehicle has an inflatable bow to seal the forward end of the channel at low speed, or to open the channel to ram air at high speed.          BACKGROUND OF THE INVENTION       Air cushion vehicles are generally of two basic types, one type having a flexible or partially flexible skirt to contain lifting air, which leaks out under the skirt and can be controlled to some extent for balancing and steering. Usually the propulsion and directional control are obtained by separate means, such as propellers and rudders, on top of the vehicle. The other basic type has rigid side  walls surrounding an air chamber, the walls being immersed in or in sliding contact with the supporting surface to minimize air leakage. The supporting air can be used for propulsion, since the energy is well contained, but additional propulsion means is often used.

Granted: 1979-05-22
Abstract: ABSTRACT          A new closure mechanism designed for mounting on the inner sufaces of doors and the like.  In a first embodiment it includes a socket component and a bolt component, the latter including a bolt slidable in a housing and driven through a rack by a pinion with a non-circular aperture for receiving an actuator.  A key actuated lock member causes an arm to protrude into or withdraw from the path for the actuator from outside the door.  The arm is so positioned as to be backed up by other structure, so as to resist impact from outside.  In a second embodiment the pinion  normally engages both the rack of the bolt member and a short thin rack section fixed to the housing, but may be translated axially to disengage the fixed rack section and enable displacement of the bolt member, the same actuating tool which rotates the pinion being further adapted to translate it as well.  In the second embodiment, a redundant external padlocking arrangement is provided in addition to the locking member first described.

Abstract: ABSTRACT OF THE DISCLOSURE      A facsimile signal is compressed by skipping the con-tinuous white cells longer than a predetermined length, and the compressed facsimile signal is transmitted in an analog form.   When some portion of a facsimile signal is deleted due to the absence of s black cell in said portion, an f-signal indicating the deletion of said portion is inserted at the head of the deleted portion.   The amplitude of the f-signal is twice as high as the highest level of a picture signal thus a reception station can differentiate the f-signal from a picture signal.   The compressed facsimile signal is modulated to an AM.PM.VSB signal (Amplitude Modulation-Phase Modulation-Vestigial Side Band Modulation), and is transmitted to a communication line.   When the reception station recognizes said f-signal, a predetermined number of white cells are inserted automatically on a printing paper at the reception station.

Abstract: THRUST COLLAR                 ABSTRACT OF THE DISCLOSURE     Disclosed is a thrust retaining device for positive axial securing of a part on a smooth shaft or within a smooth bore without shoulders, threads, grooves or holes.  The thrust retaining device for use on a shaft includes a contractible inner collar ring for retaining thrust by having one end positioned against the part to be secured, an outer collar ring to be placed over the inner collar ring for contracting it, and loading screw means attached to the outer ring for applying axial force to the outer ring.  The inner ring has an inner surface for gripping the shaft when contracted and an outer surface which is axially inclined at a shallow angle and matches an axially inclined inner surface of the outer ring.  At least one of the axially inclined surfaces of the inner ring and outer ring is coated with a stable anti-friction material preventing metal-to-metal contact at static pressure.  The shallow angle of the inclined surfaces and the slippery anti-friction material offer less resistance to axial sliding of the outer ring on the inner ring than sliding of the inner-ring on the shaft.  Therefore, axial force applied to the outer ring in the direction of angle inclination causes contraction of the inner ring and gripping of the shaft.
