Abstract: An optical pattern tracing system of the type having a tracing head with a scanner that projects a photocell onto a pattern in a closed path and provides two signals for each complete path across a line with an approach control for driving the tracing head toward the pattern-line that permits the operator to preselect either clockwise or counterclockwise tracing. The tracing head approach control includes circuitry that selectively blocks the first or the second pulse from the photocell and then terminates the blocking function shortly after the line is reached. An improved line detector is also disclosed that detects the true center of the line to be traced, and a dual pulse detector is also provided that assures that the scanner is fully locked onto the line prior to switching from manual to automatic control.

Abstract: A warning system for detecting a burned out or defective bulb for a motor vehicle is disclosed. A transmitting circuit is connected to detect current flow through the bulb to be monitored. Failure of the bulb to draw current causes the transmitting circuit to produce a series of small voltage pulses on the battery line. These pulses are detected by a receiving circuit which causes an outage indicator light to be illuminated.

Abstract: An optical scanner for a pattern tracing system for scanning an irregular two-dimensional pattern using an optical beam deflection principle. A scanning head is non-rotatably mounted above the pattern on a frame moveable in two coordinate directions. The scanning head reflects an image onto the pattern by a pivotally mounted mirror in the scanning head and is deflected at high frequency in two normally orthogonal planes by the interaction of a pair of perpendicularly related electromagnets with a permanent magnet. The geometric axis of the mirror nutates around a scan axis to provide a generally circular scan image on the pattern. The axis about which the mirror nutates, referred to as the scan axis, is shiftable from a fixed reference axis to achieve offsets for the scan image to provide both forward offset and "kerf" offset perpendicular to the forward offset. A control circuit derives out of phase alternating signals for the two scanner coils to cause this nutational motion of the mirror. The offset of the axis of nutation from the reference axis is effected by the application of direct current signals to these coils.
Abstract translation: 一种用于使用光束偏转原理扫描不规则二维图案的图案追踪系统的光学扫描器。 扫描头不可旋转地安装在图案上方可在两个坐标方向上移动的框架上。 扫描头通过扫描头中的可枢转地安装的反射镜将图像反射到图案上，并且通过一对垂直相关的电磁体与永磁体的相互作用在两个正常正交的平面中以高频率偏转。 镜子的几何轴围绕扫描轴线驱动，以在图案上提供大致圆形的扫描图像。 被称为扫描轴的反射镜螺母的轴可以从固定的参考轴移动，以实现扫描图像的偏移，从而提供垂直于前向偏移的向前偏移和“切迹”偏移。 控制电路导出两个扫描器线圈的异相交流信号，从而引起反射镜的这种运动。 章动轴与参考轴的偏移是通过直流信号施加到这些线圈来实现的。

Abstract: A contour tracing apparatus in which the coordinate drive motors are cantilever supported on simple plates and needle thrust bearings to permit the motor pinions to be spring biased into engagement with the respective racks for moving the scanning head and associated tool. Kerf offset is provided by rotation of the scanning head optical assembly about a pivot member, which can be translated along a zero kerf adjustment line to provide forward offset. The pivot member is also eccentrically rotatable in response to rotation of the optical assembly about another axis to properly align the photocells of the optical assembly with a zero kerf mark. The optical assembly includes a plurality of lamps spaced about the photocells and one integral lens structure having annular prism surfaces encircling a convex lens surface to direct light from the lamps to the contour and from the contour to the cells.

Abstract: A circuit for safely admitting fuel to a burner, igniting the fuel, detecting the presence of flame at the burner, and preventing the escape of unburned fuel from the burner if ignition is not accomplished or the flame is interrupted. An initiation circuit operates a control signal generator during a time delay period and a valve operating circuit opens a fuel valve to admit fuel to a burner. An igniter circuit is operated in response to energization of the valve operating circuit to produce sparks for ignition of the fuel. A flame detector circuit powered by the valve operating circuit detects the presence of flame and, in response, the operation of the control signal generator is maintained and the operation of the ignition circuit is interrupted. The operation is fail-safe, the detection of flame is reliable despite power supply variations, and no power supply transformer or valve operating relay is required.

Abstract: A simplified gear drive mechanism for an indicating device such as a clock. The output shaft of the indicator's drive motor carries an eccentric which orbits a multiple gear tooth orbiting gear. One gear on the orbiting gear engages a stationary ring gear having a different number of teeth while another gear on the orbiting gear engages an output ring gear having a different number of teeth. This output ring gear may, for example, be employed to drive the minute hand of a clock. To provide multiple indicators such as required in a clock, a second orbital gear train is provided having an eccentric on the output gear of the first gear train for the purpose of orbiting an orbiting gear in the second gear train. An output ring gear in the second orbiting gear train is employed to drive the hour hand of the clock. In another embodiment of the present invention, a similar orbiting gearing arrangement is employed for driving a digital indicator, such as a digital clock.

Abstract: A platform type weighing scale comprising a differential capacitor transducer having one double-segment movable plate attached to an elongated weighing beam and two double-segment fixed plates attached to a U-shaped channel. The weighing beam is housed within the cavity defined by the channel. The ends of both the weighing beam and the channel are fixed to tape-pulley supported structures to produce turning moments which move the center of the weighing beam in a vertical plane substantially more than the channel is moved in the same plane. This difference in the relative position of the weighing beam and channel translates into a weight responsive change in the relative position of the fixed and movable capacitor plates to produce a weight readout.

Abstract: A particulate products of combustion detector having a light emitting diode and a photovoltaic solar cell coupled one to the other to serve as a particulate or smoke sensor. A free-running multivibrator periodically pulses the light emitting diode to corresponding pulses of light emission having a first pulse-repetition frequency of about 80 Hz. and a duty cycle of about five percent. The output of the solar cell is connected to the input of a ringing amplifier to generate at the amplifier output a ringing pulse sequence having the same pulse-repetition frequency as that of the light element emissions in response to the detection of the particulate products of combustion. The ringing amplifier has a passband of about 500 Hz. centered about a frequency of about 1000 Hz. A detector is connected to the output of the ringing amplifier to generate a peak voltage responsive and proportional to the greatest voltage amplitude of each ringing pulse, namely, that of the first half-cycle of each ringing pulse. A bistable flip-flop is connected to the output of the peak voltage detector. When a peak voltage greater than a threshold magnitude is applied to the flip-flop indicative of the detection of the products of combustion, the circuit is driven to its second stable state, thereby actuating a smoke alarm relay.
