摘要:
A latch arrangement includes a lever movable in response to movement of a door lever. A controller is configured for selectively preventing movement of the lever. The controller includes a mono-stable blocking element in the form of a bi-metallic strip which can be operated such that a distal end acts to block movement of the lever. The controller also includes a bi-stable blocking element having a nib that can be moved to an extended position to block movement of the lever. Both blocking elements can be operated at the same time. When either of the blocking elements are arranged in the path of the release lever, unlatching of the door is prevented.

A foot orthosis device which may be used with footwear to provide arch support for the purpose of relief of physical discomfort such as pain of the foot due to such conditions as over use of longitudinally directed muscles, tendons, and ligaments located between the metatarsal and calcaneal section of the bottom of a human foot. The orthosis device can placed between the existing removable sole and non-removable platform, or above the non-removable sole, or may be integral with a portion of the footwear.

A radio receiver is configurable to operate in both low-IF and zero-IF modes with maximum re-use of of analogue and digital circuitry between modes. The receiver comprises a quadrature down-converter (108,110,112,114) for generating in-phase (I) and quadrature (Q) signals at an intermediate frequency and a complex filter (516) for performing image rejection filtering. In the low-IF mode, one of the outputs (Q) of the filter (516) is terminated, the other (I) is digitised by a non-complex ADC (520), then the digital signal is filtered and decimated. Quadrature-related IF signals are then re-generated before down-conversion and demodulation. In the zero-IF mode, both outputs of the filter (516) are digitised and processed in parallel before demodulation. By enabling analogue-to-digital conversion and channel filtering to be performed at low-IF on non-complex signals, use of just two non-complex ADCs (120,1620) is possible, thereby avoiding duplication of circuitry and providing significant power savings.

A system and method for improving the input return loss in RF amplifiers is disclosed. One embodiment of the present invention amplifies only one of the two output quadrature signals of 3 dB coupler in an amplifier module while substantially maintaining a constant impedance at the input to the 3 dB coupler. This removes one of the design constraints for designing the input network for an amplifier module thereby allowing for more flexible amplifier designs and ease of cascading amplifier modules. One embodiment of the present invention improves the input return loss of an RF amplifier pallet in a cascaded-stage power amplifier circuit for a television transmitter including a 3 dB coupler by replacing one of the two amplifiers connected to the output of the 3 dB coupler with an electrical circuit of substantially equivalent impedance to the input impedance of the non-replaced amplifier.
摘要:
A spring tooth chisel plow has its upper shank secured within a channel retainer pivotally mounted adjacent the rear edge of the retainer to a mounting bracket secured to a tool bar. The shank of the chisel plow is held within the channel retainer by a transverse clamping bar positioned radially from the main pivot, the forward end of the shank being fixed to the channel retainer. The upper surface of the retainer normally abuts a complementary surface on the mounting bracket, which supports an upwardly extending compression spring assembly. A tension bolt pivotally connects the forward end of the retainer to the upper end of the compression spring assembly, whereby force exerted on the chisel point of the plow is resisted by the compression spring assembly.

A soil conditioner for use in combination with a cultivating implement drawn behind a tractor to break up the soil and leave a prepared seedbed in a single operation. The conditioner is mounted to a framework extending rearwardly behind the cultivator. It comprises a set of reels each mounted to the framework for free rotation about a transverse axis. Two sets of axial blade members are provided about each reel. The blades are equiangularly spaced about the axis and are arranged so that each blade of one set is angularly spaced midway between adjacent blades of the other set. The first set of blades include ground-engaging edges spaced a first radius from the axis. The corresponding edges of the remaining set of blades are spaced a second radius from the axis that is less than the first radius. The different radii of the two sets of blades enable the conditioner to be towed through a field, with the freely-rotating blades breaking up clods of dirt left by the cultivator, without the blades becoming clogged with dirt. The conditioner also includes an adjustment structure for elevationally adjusting the blade edges relative to the cultivator. This adjustment structure includes adjustment brackets each connecting two portions of the soil conditioner frame. Each of these brackets is provided with a plurality of apertures. These apertures are selectively aligned with a set of corresponding apertures on one of the two portions of the soil conditioner frame. By placing bolts through the aligned apertures, the elevation of the blade edges is selectively adjusted.

A tire apparatus is provided, the apparatus including a tire body for attachment to a wheel rim to define a first inflatable volume. An inner chamber defines a second inflatable volume which is located within the first inflatable volume of the tire body. A first fluid communication path is provided between the first and second inflatable volumes and a second fluid communication path is provided between the first inflatable volume and the atmosphere. A first valve opens and closes the first fluid communication path, and a second valve opens and closes the second fluid communication path. The tensile strength and pressure-containing capacity of the material structure of the second inflatable volume is greater than that of the tire first inflatable volume. A first fluid pressure within the first inflatable volume of the tire body is optimisable by opening the first valve to allow pressure transfer from the second inflatable volume into the tire body, and/or opening the second valve to allow pressure to vent from the tire body to atmosphere. A vehicle wheel and active tire pressure control system incorporating the tire apparatus are also provided.
摘要:
A latch assembly includes a chassis, a latch bolt moveably mounted on the chassis and having a closed position for retaining a striker and an open position for releasing the striker, a pawl having an engaged position at which the pawl is engaged with the latch bolt to hold the latch bolt in the closed position and a disengaged position at which the pawl is disengaged from the latch bolt, thereby allowing the latch bolt to move to the open position, an eccentric arrangement defining an eccentric axis and a pawl axis remote from the eccentric axis. The eccentric arrangement is rotatable about the eccentric axis, and the pawl is rotatable about the pawl axis. When the pawl moves from the engaged position to the disengaged position, the eccentric arrangement rotates in one of a clockwise and a counter-clockwise direction about the eccentric axis. With the pawl in the engaged position, a force applied to the pawl by the latch bolt creates a turning moment on the eccentric arrangement in the one of the clockwise and counter-clockwise direction, and the eccentric arrangement is prevented from rotating in said one of the clockwise and counter-clockwise direction by a moveable abutment.
