Abstract: ABSTRACT OF THE DISCLOSURE In a valve structure, a valve plug apparatus to pro-vide a leak-tight valve shut-off, is disclosed. The valve structure includes a valve body provided with an inlet passage, an outlet passage and an internal web portion intermediate the inlet and outlet passages. A closeable passage-forming means is arranged in the web portion and a two-member valve plug is mounted on a valve stem for controlled axial movement within the web portion and operate to close said closeable fluid passage-forming means to shut the valve. In accordance with the inven-tion, the two-member valve plug comprises a lower plug member and an upper plug member which are in a generally axially spaced relation on the valve stem. Packing means is held in a snug-fitting condition between the lower and upper plug members by an axially resilient member which acts between one end of the valve stem and the valve plug to urge the lower and upper plug members together. When the two-member valve plug closes the closeable fluid passage-forming means, a force is transmitted by the valve stem directly through the upper plug member to the packing means to form a leak-tight seal for the valve plug. The stem force is also transmitted through the packing means and lower plug member to generate a seating force between the valve plug closeable fluid passage-forming means for tight valve shut-off.

Abstract: 6506   INVENTORS:  IVAN DE MESMAEKER and PETER M?LLER           CAN     INVENTION:  APPARATUS FOR FAULT DIRECTION-COMPARISON                   PROTECTION     ABSTRACT OF THE DISCLOSURE                  With heretofore known directional comparison protection systems working with fault direction detectors at both ends of a line section which is to be protected and data transmission between both end stations as well as trans-mitters and receivers and comparison-evaluation devices for narrowing or sectionalizing the location of the fault site with resepct to the line section to be protected, the reliability of such sectionalizing procedure, especially in the case of faults near to an end station, when working with series capac-itors or capacitance, is dependent upon the response of the protective gap of such capacitors.  With non-response there are produced transient oscillations which can falsify the dir-ectional determination.  The invention solves this problem by using distance protective relays as the fault direction detectors with line replica or image impedance, which can be switched in the sense of a zone staggering protection.  The image im-pedance for the directional comparison protection is set greater than the impedance of the line section to be protected, prefer-ably is approximately equal to the forward network impedance of the relevant station.

Abstract: ABSTRACT When hiking in the woods or mountains it is known that making noise with a noisemaker as you walk reduces the risk that you will be attacked by a bear.  This is because most attacks by bears occur when a bear is startled by an unexpected encounter with a person, and can be averted if bears are given some warning that a person is coming. This invention, entitled Bear Aware, is a noisemaker designed specifically for use by hikers in bear country. It consists of a loud alarm buzzer that is repeatedly turned on and off by a solid state timer.  The timer permits the hiker to set both the length of the alarm soundings and the length of the silent intervals in between.  The alarm and the timer are enclosed in a watertight case, and the unit is completely portable and can be worn on a belt.  Unlike some other types of noise-makers used by hikers, e.g. personal distress alarms, Bear Aware provides hands-free operation by automatically re-sounding according to the alarm schedule preset by the hiker.  Bear Aware is also unlike noisemakers such as bells (worn by some hikers on their backpacks) that make only unceasing or very frequently repeated noise which may become irritating to the user.  With Bear Aware, the adjustable silent periods between alarm dis-1.     2.   charges permit the hiker to enjoy the sounds of Nature.

Abstract: ABSTRACT OF THE DISCLOSURE           A vehicle mounted spray boom assembly includes a break-away spray boom and shock absorbing means for absorbing the shock on the boom assembly when a boom returns to normal position after striking  an obstacle.  The shock absorbing means includes a swing cylinder for rigging in and rigging out the spray boom and a tilt cylinder for tilting the boom when the boom has been rigged out.          Upon occurrence of shock after an obstacle is struck, a portion of the hydraulic fluid in the swing cylinder is forced into the tilt cylinder to lift the spray boom to dissipate the shock.  In addition, another cylinder may be provided for absorbing shock imparted to the boom due to vertical movement of the boom.  Also the swing cylinder and tilt cylinder are hydraulically connected in parallel so that when rig out has been completed, pressurized hydraulic fluid continues to be ported to the tilt cylinder to elevate the end of the boom.

Abstract: A B S T R A C T           In a refrigerator cabinet operated with an absorp-tion refrigerating apparatus having an evaporator for cooling a refrigerating chamber and an evaporator for cooling a freezing chamber. The refrigerant condensate is supplied to the freezing evaporator and partly evaporated, while the residue flows into the refrigerating evaporator. At very low ambient temperature the freezing evaporator receives too little refrigerant, or else the refrigerating evaporator too much. This situation is avoided in that an evaporator part for cooling of the freezing chamber is supplied with refrigerant condensate at short intervals during periods when the thermostat for the refrigerating chamber is in an off position.

Abstract: FRONT-OF-DOCK DOCKBOARD Abstract of the Disclosure A dockboard to be attached to the front of a loading dock.  The dockboard includes a deck plate, the side edges of which are pivotally connected to guide bars that are movable vertically within guideways formed in the upper portion of a rectangular frame.  The frame is mounted for vertical movement within guides mounted on the front face of the loading dock, and the frame and deck plate are partially counterbalanced to an upper position by a counterweight mechanism that is connected to the frame through a synchronized chain drive.  The deck plate is stored in a vertical position below deck level and, in use, is lifted to a raised position above dock level, pivoted to a substantially horizontal posi-tion and then lowered into engagement with the bed of a carrier located in front of the dock.  The pivotal connection between the deck plate and the guide bars enables the deck plate to tilt diagonally as a load moves across the deck plate in the event that the bed of the carrier is not parallel to the upper surface of the dock.  When the carrier moves from the dock, the deck plate will swing to a vertical position and the frame will lower by gravity to move the deck plate to the vertical storage position.
