A navigation device comprises a flat substrate, a compass rose carried on the substrate, an elongated cord affixed at one end to the center of the compass rose and at least one linear distance scale on the substrate having its origin coincident with the center of the compass rose. In use, the navigation device is placed on a navigation chart, so that the center of the compass rose lies over a predetermined point of origin on the chart and the North compass direction of the rose is in parallel al...

A display heading for notions is particularly designed for use with a perforated board support that is utilized to merchandise a plurality of notions in sets of common series or groups. The notions display heading is made of plastic with rear-surface fasteners having hook like elements that project through selected apertures in the perforated board support.

A curtain heading of pinch-pleated assemblies of butterfly configurations is stiffened by plastic hinged wing stiffeners adapted to be inserted into the open ends of the pinch-pleated assemblies to hold the shape of the pleats and removable therefrom when the curtain is to be washed or dry cleaned. These stiffeners being made of two wings to accommodate the two outside pleats or with a central wing to accommodate the partial inner pleat of the assembly. These same stiffeners when provided with a...

An apparatus (100) and process for multistep heading of elongated stock to form a brush contact (10) with a relatively great reduction in the length of the wire stock material (386) achieved during successive heading steps, including a rotary holder plate (112) mounting a series of blank clamping holders (166) indexed through a series of stations and a series of coning dies (240) and punches (244) carried by independently actuated tooling plates (114, 116) which are axially advanced during formi...

A heading reference system (100) for sensing vehicle heading relative to fixed inertial space is mountable in a vehicle such as a land-based vehicle and includes a two-degree-of-freedom (TDF) dynamically tuned gyroscope (150) responsive to vehicle rotation about pitch and yaw axes for generating rate signals indicative of the rotation. A caging loop (160) generates force signals for torquing the gyroscope (150) to a null position. A pair of accelerometers (186, 187) are responsive to misalignmen...

A heading indicator for power-driven units, especially land vehicles, is disclosed which comprises a rate gyro, an integrator controlled by the gyro and a comparator for generating an output signal proportional to the difference between the instantaneous value of azimuthal information from the integrator and a corresponding information from a magnetic course transmitter. The output signal is supplied to a circuit controlling the integrator so as to correct its output azimuthal information in res...

A goose or duck decoy comprising a body portion substantially in the shape of a goose or duck or other wild fowl, the body portion having a flat surface mounted on the body near the posterior of the body along the top center line of the body perpendicular to the top surface of the body, a head portion removably attached to this body portion and a mounting stake, the mounting stake comprising a tubular rod having a pointed end and a flat end and having a first flat, bearing surface attached to th...

To cut and form heads on a plastic stud or rod, particularly in binding papers together, a rotating tool of special construction is forced against a conical concave cam surface. The tool has a hollow shank with at least one flexible arm extending therefrom, said arm formed with a head, the arm being normally outwardly slanted so that the head is spaced outward of the axis of rotation. Each head has an inward projecting blade at its distal end. The space between the axis and the inner edge of the...

A smoothing system for a ship's heading indicated by a compass. The rotor of an azimuth (directional) gyro is in a cardanic suspension in a gyro housing mounted on a stabilized platform. During a run-up mode, a "heading shaft" is servo aligned directly with the compass position while the azimuth gyro is slaved to a position angularly related to the heading shaft. During a running mode, the servo error outputs are exchanged with each other so that the heading shaft is then slaved to the compass v...

The invention relates to a process and an apparatus for heading and eviscerating fish in which the head and the entrails are integrally removed from the body of the fish. According to the invention, only the neck of the fish is cut, after which the head is turned down through approximately 90.degree. in relation to the axis of the body and, finally, the head undergoes a relative displacement along the body of the fish towards the rear thereof. As a result, the fish is completely eviscerated. The...
