摘要： A machine which can be used selectively for crossed axes gear shaving employing a gear-like shaving cutter having cutting edges in the sides of its teeth, and as a gear rolling machine employing a die in the form of a hardened gear. Provision is made for relative traverse while shaving in a direction occupying a plane parallel to the axes of the gear and tool, and for incremental infeed during shaving and continuous infeed during gear rolling.

摘要： A sofa bed assembly including a support means, a seat frame, a back frame, and connection means supporting the frames on the support means for pivotal movement relative to one another and movement between an upright seat position and a lowered bed position. A pair of reaction plates extend from the back frame and a pair of cam members are rotatably connected to the seat frame in a pendulum manner and include lower cam surfaces which engage the top surfaces of the reaction plates upon upward pivotal movement of the seat frame when the bed position so that upon downward movement thereafter the back frame is moved to the upright seat position. Upon slight upward pivotal movement of the seat frame when in the seat position, the cams will fall under the force of gravity to a release position whereby the frames may be moved to the bed position. There is also included a latch means comprising a flange extending from the support means to coact with a slot in a rear member of the seat frame. The slot is disposed in an overlapping position above and rearwardly of the flange when the assembly is in the seat position whereby the flange may be moved through the slot to the overlapping position as the frames are moved to the seat position to prevent movement of the frames by coaction of the flange and the rear member of the seat frame until the seat frame is pivoted upward slightly to align the slot with the flange whereby it may be moved forwardly to move the rear member forwardly of the flange.
摘要翻译：一种沙发床组件，包括支撑装置，座椅框架，后框架和将框架支撑在支撑装置上以相对于彼此枢转运动的连接装置以及在直立座椅位置和降低的床位置之间的运动。一对反作用板从后框架延伸，并且一对凸轮构件以摆式方式可旋转地连接到座椅框架，并且包括下凸轮表面，当下列凸轮表面在座椅框架向上枢转运动时接合反作用板的顶表面，当床位置使得当向下移动时，后框架被移动到直立座椅位置。当处于座椅位置时座椅框架稍微向上枢转运动时，凸轮将在重力作用下落到释放位置，由此框架可以移动到床位置。还包括闩锁装置，其包括从支撑装置延伸的凸缘以与座椅框架的后部构件中的狭槽共同作用。当组件处于座椅位置时，狭槽设置在凸缘上方和后方的重叠位置，由此当框架移动到座椅位置时，凸缘可以通过狭槽移动到重叠位置，以防止框架的移动通过凸缘和座椅框架的后部构件的共同作用，直到座椅框架稍微向上枢转以使槽与凸缘对准，由此可以向前移动以使后部构件向前移动。

摘要： A DC to AC converter network in which a control signal produced by summing input DC with a network DC feedback signal, the control signal then being integrated and used to control the gate of a field effect transistor to operate the same as a variable resistance. A phase-splitter circuit provides out-of-phase AC components from an AC reference signal, and one of the components so produced is coupled to the other through the field effect transistor, to produce a resultant AC output whose phase and amplitude differ from the reference AC signal as a function of the integrated DC control signal. The resultant AC signal is fed to an amplifier and summed at the input thereof with a feedback signal from the amplifier output, and the latter is further amplified and fed to a phase-sensitive demodulator, to which the AC reference signal is also coupled. The demodulator output comprises the network feedback signal which is summed with the input DC, such that the amplified resultant AC signal is tied to the network input and will linearly follow the DC input signal.

摘要： A box spring assembly including a frame having a pair of opposite and generally parallel extremities interconnected by ends with a plurality of spring members extending between the extremities, Each spring member is defined by an integral wire having parallel and spaced fishmouth sections interconnected by a generally U-shaped support section. The fishmouth sections are interconnected at the lower ends thereof to the extremities of the frame with the U-shaped sections of pairs of spring members being disposed in overlapping relationship with the base portions of the U-shaped sections being connected to a border wire.
