Abstract: "Actuating Mechanism"              Abstract of the Disclosure.     An actuating mechanism for example for an electric switch comprises a driving member, a driven shaft and a transmission means through which the driven shaft is driven by the driving member through a certain angle of rotation after a predetermined number of revolutions of the driving member.   Actuating means carried by the driven shaft are operative at a predetermined angular position of the driven shaft.   An adjustment shaft is provided which can be rotated to rotate the driven shaft through the transmission means, a clutch being connected between the driving member and the transmission means to permit by disengagement of the clutch the adjustment shaft to rotate the driven shaft relatively to the driving member.   A radial projection, e.g. an arm, is provided on the driven shaft in a fixed angular relationship to the actuating means thereon, and a removable abutment stop for the radial projection is provided at a predetermined angular position with respect to the axis of the driven shaft to limit the angular displacement of the driven shaft by the adjustment shaft.

Abstract: SUPPLY FOR PROVIDING UNINTERRUPTIBLE          D-C POWER TO A LOAD_ ABSTRACT OF THE DISCLOSURE A system for supplying uninterruptible d-c power to a load,  When the system operates in its normal mode, d-c load power is provided by the combination of a rectifier and a power switch.  The d-c output of the rectifier may be used by a d-c to d-c down converter to recharge and maintain a battery if a separately powered source is not available for that purpose. A d-c to d-c up converter provides a relatively high amplitude d-c voltage from the battery voltage.  The amplitude of this voltage is lower than the amplitude of the d-c output of the rectifier in the normal mode.  When the amplitude of the rectifier output falls below the d-c to d-c up converter output voltage, the system changes to its failure mode and the battery provides d-c power to the load.  The operation of the down converter if it is included in the system is inhibited.

Abstract: ABSTRACT         An apparatus for storing unused felt pens for an electronic input board system is described.  For writing multiple color information on the electronic board, colored felt pens are used and one of these color felt pens is replaceably mounted in a pen holder.  To prevent drying out of ink, the apparatus is provided with caps for the unused felt pens. The apparatus comprises a series of wells at the bottom of each of which is provided an airtight cap.  When the holder is inserted, the pen being held in the holder is retained in the well by a lever mechanism.  To pick up a desired pen, the empty holder is inserted into the appropriate well and the appropriate lever mechanism manually operated to release the pen which is then secured in the pen holder.  The wells are each provided with sensors for indicating the absence or presence of a pen.  Each well may be designated for a particular color (or pen thickness) and so the system can always automatically identify the color (or pen thickness) in use at any time.

Abstract: METHOD FOR SCREENING LASER DIODES            Abstract of the Disclosure A method for screening double heterostructure laser diodes before mounting and packaging is disclosed.  At a normal laser diode operating temperature, a range of pulsed current is passed through the laser diode and the lasing threshold current and slope efficiency of the laser diode are monitored.  The laser diode is then subjected to a burn-in process in which it is driven at a high junction temperature for an extended time period.  Subsequently the lasing threshold current and slope efficiency are again monitored by applying the same range of pulsed current at the normal operating temperature.  If either the threshold current or the slope efficiency have changed by more than a predetermined amount, the laser diode is rejected.  Otherwise, the laser diode is gauged as likely to have a lifetime greater than a predetermined value at normal operating conditions so warranting further testing prior to installation into a laser package.     - i -

Abstract: ABSTRACT           The present invention minimizes shock hazard in using a touch start plasma torch.  The resistance between the  torch  tip  and  the  workpiece  is  compared  to  a predetermined value  set by estimating  the  resistance between  a  person's  hand  to  ground  under  the  most unfavorable conditions.  In the preferred embodiment, such comparison is performed by supplying an AC voltage to a resistor in series with a torch tip, the resistor having a resistance equal to the predetermined value.  The peak voltage at a point in the circuit connection between the resistor and torch tip is sensed and if such peak is less than half of the peak voltage of the AC voltage supplied to the resistor and torch tip, the resistance between the torch tip and ground is less than the predetermined value and a control signal will be generated.  A relay means will switch on the power supply supplying high voltage between the cathode and the workpiece only when it receives the control signal indicating that the resistance between the torch tip and ground is below the predetermined value.

Abstract: ABSTRACT OF THE DISCLOSURE      An oleodynamic steering control device for vehicles having a straight traveling stabilizer, the device comprising a cylindrical member containing a reciprocatable or rotatable element connected to the main steering system to generate a fluid pressure which is transmitted to a steering actuator on an axle to be steered.  The device provides a fluid by-pass to a reservoir for a certain range around a position corresponding to the straight traveling condition of the vehicle and thus relieves the pressures generated by small deviations from straight traveling, which occur at relatively high speed and which are thus not transmitted and multiplied on the steered axle which is thus stabilized, affording greater traveling safety.
