摘要： A rod casing for activating vertically arranged latch bolts, the casing and latch bolts arranged in an active stile of a door and engageable to a door frame. The rod casing provides a vertically slidable actuator cam engageable by both a lock/unlock actuator and a delatch or dogging actuator. The lock/unlock actuator and the delatch actuator are rotatably mounted upon a spindle piece which itself is rotatable by a user such as by a key-activated lock cylinder. The lock/unlock actuator when rotated slidingly abuts the actuator cam and drives the actuator cam vertically upward to cause unlatching of the latch bolts. The delatch actuator, upon rotation of the spindle piece in an opposite direction underlies the actuator cam and dogs the actuator cam in its vertically risen position. To deactivate the delatch actuator, the lock/unlock actuator can be rotated to interfere and displace the delatch actuator to release the actuator cam from the dogging position. The actuator cam is composed of a resilient material to allow the delatch actuator to engage the actuator cam in a spring-like or resiliently compressible fashion to help hold the actuator cam in its dogging position.
摘要翻译：用于启动垂直布置的闩锁螺栓的杆壳体，所述壳体和闩锁螺栓布置在门的主动台中并可接合到门框。杆壳提供可由锁定/解锁致动器和分拣或卡扣致动器接合的可垂直滑动的致动器凸轮。锁定/解锁致动器和脱钩致动器可旋转地安装在主体部件上，主轴部件本身可由用户旋转，例如通过钥匙启动的锁芯。当锁定/解锁执行器旋转时滑动地抵靠致动器凸轮并且致动器凸轮垂直向上驱动以使闩锁螺栓松开。当主轴件沿相反方向旋转时，分条致动器在致动器凸轮下方并且在致动器凸轮处于其垂直上升位置时被阻挡。为了使去毛刺致动器失效，锁定/解锁致动器可以被转动以干扰和移动脱钩致动器，以将致动器凸轮从锁定位置释放。致动器凸轮由弹性材料组成，以允许分段致动器以类似弹簧或可弹性压缩的方式接合致动器凸轮，以帮助将致动器凸轮保持在其卡定位置。

摘要： An electronic circuit for receiving input electrical power at a lower frequency and for energizing a load at a higher frequency. The electronic circuit has a rectifier for rectifying the input electrical power received on an input thereof and a pre-regulator for changing the rectified AC voltage provided by the rectifier to a source voltage. The electronic circuit further has a non-resonant inverter for providing electrical power at the high frequency to the load and includes first and second switches and is connected to the pre-regulator and to the load circuit. A logic circuit is responsive to a sensed signal representing only current flowing in the first and second switches for operating the first and second switches. The frequency of current in the load circuit varies for any substantial change in the magnitude of the source voltage, for any change in load impedance, and for any change in a set point value. A device for setting the set point value is connected to the logic circuit. Finally, a reactance circuit is provided and connected in circuit with the load. The peak amplitude of current in the load has a peak value determined by the set point value. The device for setting the set point value can be a replaceable element having a predetermined relationship to the type of load connected to the electronic circuit or to the desired light output level. Also, the device for setting the set point value can be a variable element for selecting the set point value from a range of set point values and thereby changing the peak amplitude of current in the load. The variable element can also be controlled by a signal originating remotely from the logic circuit in the ballast.

摘要： An improved door closer is provided which has a back checking arrangement including a loosely held resilient cushion bar which is engaged by a metallic shield abutting sliding cam plates during a final few degrees of opening of a door to provide an increasing resistance against further opening of the door. The shield preferably engages the cushion bar approximately 4.degree. prior to a normal full open position of the door. Selective thickness of the cushion bar provides either a 90.degree. full open position of the door or a 150.degree. full open position of the door without additional adjustment.

摘要： The invention disclosed herein provides a panic exit device for doors having in their active side vertically operating bolts extending from the top and bottom of the door and a mechanism for retracting the bolts. Usually, the retracting mechanism may be activated by using a key in an exterior door lock or by depressing a panic bar on the interior of the door. The improved panic exit device of this invention provide a device for actuating the bolt retraction mechanism which is mounted inside a semi-hollow enclosure which is integral with the door. The mounting is accomplished with screws hidden from view by the glass pane securing mouldings. The panic exit device of the invention also provides an improved dogging mechanism to lock the actuator device in the actuated position, while simultaneously preventing excessive play in the panic bar.

摘要： A plaster frame or base for recessed lighting fixtures has hanger bar receiving corners which are bendable to accommodate parallel or perpendicular axis orientation relative to ceiling joists or suspension grids. The frame spans the space between a pair of hanger bars and its corners have a plurality of mountings to accommodate different types of hanger bar such as flat horizontal, flat vertical, and adjustable interlocking hanger bars. The frame is preferably a rectangular metal plate with a flat base having upstanding side flanges, a fixture receiving aperture through the base between the flanges having a depending skirt or collar to surround and mount the fixture, mountings on the base for a junction box adjacent the aperture, and bendable hanger bar securing corners. The plate is sufficiently narrow to fit through the conventional ceiling aperture for the fixture.

摘要： A paint roller guard assembly includes a paint shield adapted to support a paint roller, and a separate handle having a solid threaded mounting end which is received in a threaded connector formed on a side wall of the paint shield to attach the handle to the paint shield during use of the paint guard assembly for painting. The handle is removable from the paint shield to permit a water hose to be connected to the paint shield to supply water under pressure which is discharged through an elongated slot formed through the side wall of the paint shield to impact the paint roller causing it to rotate and simultaneously wash residual paint from the paint roller.
