Abstract: ABSTRACT OF THE DISCLOSURE         An automatic level control (ALC) circuit for  use with a light beam scanning apparatus which apparatus is used to inspect printed circuit boards is disclosed.  The printed circuit board contains a pattern of conducting surfaces on an insulating substrate.  Light interaction with the conductors causes a detector assembly portion of the scanning apparatus to produce a first set of signals called conductor signals while light interaction with the substrate causes the detector assembly to produce a second set of signals called substrate signals.  A first corrected reference signal corresponding to the conductor signals is generated during an initial adjustment period and is provided to summing circuitry where it is summed with conductor and substrate signals from the scanning apparatus.  When the first reference signal is summed with conductor signals a near zero level summed conductor signal is produced.  Substrate signals added to the fixed level first reference signal produce summed substrate signals with a non-zero value.  A programmable high voltage power supply portion of the detector assembly is responsive to adjustment signals to change the level of the substrate signals produced by the detection assembly.  During second time intervals of selected beam sweeps during the adjustment period when only substrate signals are produced, the summed substrate signals are compared with a preselected substrate value and correction signals are generated in response to the comparison.  The output of the programmable power supply is changed in response to the correction signals.  Eventually, the value of the summed substrate signals becomes substantially the same as the preselected substrate value.

Abstract: ABSTRACT OF THE DISCLOSURE           A swinging door hinge assembly comprises a primary hinge and a secondary hinge.  By means of an axle rotating on a staircase-shaped axle seat in the primary hinge, the door can be opened in either direction, slowly closed, or opened at a wide angle for a long time.  The secondary hinge includes an inner and an outer eccentric axle bushing by which the secondary hinge can automatically adjust its axis to be in alignment with that of the primary hinge, i.e., in a co-axial alignment in case of the door hinge assembly generating any eccentric condition.  Otherwise, the door cannot be operated smoothly in case the two hinges are not co-axially aligned.  The door hinge assembly may be easily assembled or disassembled, between the left and right side primary hinge pieces, and also between the left and right side secondary hinge pieces.

Abstract: A B S T R A C T        Control apparatus comprising a lever, foot pedal or other operating member which is coupled to an electrical stepper motor operable, under the control of a computer say, to generate detents and feel forces resisting the movement of the member and thereby impart information to the operator.          For example, a detent or position of marked resist-ance can be introduced into the movement range of say a car throttle pedal to indicate to the driver a pedal position giving optimum economy of fuel.          The detent position can be changed within the overall range of pedal movement in dependence upon instant driving parameters such as speed.   As well as detents, programmed and/or external condition dependent feel forces can be generated.
