    Abstract: A method and apparatus for supplying gas to a vacuum drum device and which substantially reduces or eliminates the problem of particle and debris buildup in the vacuum passages of the device is provided. The apparatus supplies gas, preferably at a pressure greater than atmospheric pressure, to the vacuum ports of a vacuum drum and includes a source of vacuum, a source of gas, and a rotatable vacuum drum. The drum includes a plurality of vacuum ports on the surface thereof, with the vacuum ports communicating with a plurality of vacuum passages extending generally outwardly from the interior of the drum. A valve alternately connects the passages to the vacuum source and to the source of gas. The selective exposure of the vacuum ports to either a source of vacuum or a source of gas prevents smoke, particles, and other contaminants from being drawn into the vacuum passages of the drum during operation of the system.

    Abstract: Apparatus and method for producing diamond films. A source of free electrons is used to bombard a carbon block. Incident electrons vaporize the carbon surface, and free carbon atoms are ionized from collisions of the electrons with the carbon atoms. A collimating plate located above the carbon block includes an aperture for permitting the vaporized carbon ions to be collimated. On the other side of the collimating plate are first and second deflector plates, symmetrical with respect to the axis of the collimating plate aperture. A voltage potential therebetween produces an electrostatic field perpendicular to the axis of the aperture. Substrates located in the electrostatic field receive a carbon ion film which is essentially a diamond film structure.

    Abstract: An arrangement for mounting a radio distress beacon (1) comprises a split casing (4) which is bouyant and which is normally held together and to the deck of a vessel by a harness (7). If the vessel should sink the harness is released, the casing rises to the water surface and springs (20) overcome the hydrostatic pressure at shallow depths and force the halves of the casing apart, so releasing the beacon.

    Abstract: Disclosed herein is a rural mailbox indicator and security lock including an elongated rod designed to be moved between three positions, a first position indicating that the box is unlocked but no mail is there for pick-up, a second position wherein the box is open and mail is in the box to be picked up and a third position indicating that the box is securely locked against unauthorized entry. The elongated rod is rotatably mounted on a cam which is adjacent a locking mechanism, with the cam having a cut out portion designed to receive a latch of the locking mechanism in the third mentioned position of the elongated rod described above, with the cam further including an arcuate rim designed to interengage with a catch formed on the mail box door so that in the position of the elongated rod corresponding to locked condition, the door is prevented from being opened until the locking mechanism is released by a key.

    Abstract: A windvane powered, self-steering device for sail boats of the type employing a steering rudder and trim tab. The windvane pivots about an axis that is tiltably adjustable for light or heavy winds. The windvane axis is also rotatably adjustable with respect to the center line of the sail boat to provide course adjustment. When engaged for operation, the windvane senses the relative ship-wind direction and, when the ship is off course, translates the wind forces on the windvane into corrective movements of the trim tab and rudder to return the sail boat to course. In this operational or steering mode, the self-steering device is characterized by its ability to fully transmit wind power at all angles of tilt of the windvane axis, also, by its ability to be separately adjusted to any desired angle of tilt (wind sensitivity adjustment) or rotation (course adjustment). A preferred embodiment of the self-steering device includes means to initially employ the windvane in a trailing operation to establish a desired steering position for course (trailing mode) and thereafter to employ the windvane in a weathervaning operation for steering corrections (operational mode).

    Abstract translation: 一种采用转向舵和调整翼片的风帆式风力发电自行转向装置。 风向机围绕可倾斜调节的轻型或大风的轴线转动。 风向轴也相对于帆船的中心线可旋转地调节以提供路线调整。 风力发电机在进行操作时，感测到相对的船舶风向，当船舶离开时，将风向上的风力转化为修剪突出物和方向舵的修正运动，以使帆船返回航向。 在这种操作或转向模式中，自动转向装置的特征在于其能够在风向轴的所有倾斜角度下完全传递风力，并且通过其独立地调节到任何所需的倾斜角度（风敏感度）的能力 调整）或旋转（课程调整）。 自动转向装置的优选实施例包括在拖尾操作中最初使用风向标（SVM）以建立所期望的转向位置（后退模式）的装置，并且此后在用于转向修正（操作模式）的风向运行中使用风向标。
