摘要： A presence detector unit (PDU) of the type relying on microwave radiation provides a signal indicating movement within a defined space when such movement occurs. A source of microwave radiation within a housing projects a beam of microwave radiation directed through a side of the housing to suffuse at least a portion of the defined space. A detector within the housing senses changes in microwave radiation reflected back toward the detector. An adjustable beam occlusion structure is supported by the housing and blocks a portion of the microwave radiation emanating from the source and through the side of the housing.

摘要： A hollow block in the form of a rectangular parallelepiped when filled with water, is joined with a plurality of similar water-filled blocks to form a flood barrier. Two opposite sides of each block have connection features that connect with features on the first and third sides of adjacent blocks to form a wall of connected blocks. Top and bottom walls of each block each have an inter-tier connection feature that mates with a block in each adjacent top or bottom wall. Each block includes on each of its top and bottom walls, inter-tier connection features structured to mate with an inter-tier connection feature of a similar block in the adjacent tier.

摘要： A press for forming a workpiece with a tooling set includes an actuator assembly carrying a movable half or punch of the tooling set and having a two phase operation. In the first phase the actuator provides relatively low force in moving the punch to an intermediate position in close proximity to the workpiece. A sensor detects the position of the punch, and when the punch reaches the intermediate position provides a continue signal. The second phase of actuator operation is conditioned on occurrence of the continue signal, and uses normal high force to press the movable tooling half against the workpiece to complete the operation. The low force first phase allows obstructions of any kind to stop movement of the punch during the first phase before high force applied to the actuator may cause damage or injury to the obstruction. In a preferred embodiment the actuator assembly has hydraulic operation.

摘要： A connector cable assembly has first and second plugs wired to permit plugging into a first pair of electrical plugs with a pair of terminals in a first configuration to place the terminals of those plugs in parallel connection, and to permit plugging into a second pair of electrical plugs with a pair of terminals in a second configuration, to place the terminals of those plugs in series connection. In a commercial embodiment, such a cable assembly can be used to provide power to electrical devices such as gas valves connected to receive power in parallel from the first pair of electrical plugs, and to connect in series, safety switches connected to plugs with a pair of terminals in the second configuration. By using an adapter with specialized connections between two sets of terminals it is possible to use additional cable assemblies to connect in excess of two switches in series.

摘要： An air duct has a filter mount opening originally intended to accept a shallow filter element for filtering air entering the duct. The opening has an interior flange whose original purpose was to support the shallow filter element. This flange has interior edges defining an air passage opening. The invention is implemented a filter unit including a frame and a deep filter element mounted in the frame. The frame has dimensions allowing the filter unit to replace the conventional shallow filter element with the frame inserted into the air passage opening and closely spaced to all of the interior edges. A resilient gasket is mounted adjacent to the opening's interior flange and projects slightly into the air passage opening so as to contact the deep filter element's frame. The gasket prevents air leakage between the interior flange's interior edges and the frame. In one embodiment, the frame has a flange to mate with a surface of the air passage opening's interior flange so as to prevent air leakage and to position and support the filter unit.

摘要： A thermostat employing a lever for selecting the temperature setting has a detent mechanism for creating individual detent positions associated with temperature setting values. In a preferred embodiment the detent mechanism comprises ridges and valleys in the surface of the baseplate on which the thermostat elements are mounted. A projection on the setting lever engages the individual valleys to create the detent effect, and a edge of the cover cooperates with resiliency of the lever to deflect the lever so as to cause the projection on the lever to continually engage the ridges and valleys. Another embodiment has ridges and valleys on the edge of the cover which engage a first projection on the lever. A second projection slides along the baseplate surface and cooperates with resiliency of the lever to deflect the lever creating force urging the first projection into continual engagement with the ridges and valleys.

摘要： An actuator uses an AC motor assembly having a random chance of rotating in either direction upon stalling or first receiving power, to provide torque for operating its output member. The output member operates from one extreme position to another. Limit stops prevent the output member from moving past each extreme position. There is a limit switch which removes power from the motor assembly while the output member is at an extreme position. A startup switch supplies power to the motor assembly at each extreme position when the output member is to be driven to the other extreme position.

摘要： A rotary actuator derives its power from a synchronous motor preferably of the AC type providing constant output speed, and from a non-synchronous motor, preferably of the DC type, in a helper capacity to provide additional torque for a load. Use of certain types of non-synchronous motors to provide a portion of the maximum torque is cheaper than using a synchronous motor whose size is adequate for the maximum torque requirement. A torque limiting clutch which couples the non-synchronous motor output to the synchronous motor output allows the non-synchronous motor to run compatibly with the synchronous motor. A hysteresis coupling type of torque limiting clutch is preferred. In a preferred embodiment, both of the motors drive a gear train, with the non-synchronous motor coupled to the gear train by the torque limiting clutch.

摘要： An improved rotary read/write head assembly is particularly suitable for use with a vertical format magnetic recording medium such as tape in a magnetic recording system. A rotary element of the assembly carries a plurality of main poles whose tips are at an edge of the rotary element and kept in substantially contacting relationship with the medium. Rotation of the element causes the pole tips to successively sweep across the medium and sequentially function as the main pole of a probe head.
