Abstract: TITLE            Self-Contained Fan Clutch ABSTRACT OF THE DISCLOSURE      A self-contained fan clutch including a housing in which is contained a rotatable drive disc driven by a source of power connected to the housing and the drive disc.  Also mounted within the housing is an annular piston having an annular piston portion reciprocable within a cylinder member, the piston portion carrying a friction facing engageable with the driven drive disc when the piston is actuated within the cylinder.  The piston divides the cylinder into a high pressure side and a low pressure side with the piston, piston portion and cylinder carried by the housing with the housing having a series of fan blades mounted thereon.     The cylinder member mounts a reciprocal pump plunger actuated by a cam mounted on the driven drive disc for pressurizing the high pressure side of the cylinder which causes the friction facing of the piston portion to engage the drive disc and be rotated together with the housing and fans thereon.  The pump plunger is actuated by a thermal sensor pill.  Also included is apparatus for relieving pressure in the high pressure side of the cylinder and shunting it to the low pressure side of the cylinder there-by causing the piston to shift to the high pressure side by reason of springs carried by the housing and piston whereby the friction facing is relieved from the drive disc and the housing and fan thereon ceases to rotate.

Abstract: SAND RECLAMATION SYSTEM WITH THERMAL PIPE RECLAIMER APPARATUS ABSTRACT OF THE DISCLOSURE         A system (10) particularly suited for treating solid, granular and aggregate material by means of thermal reclamation.  The subject system (10) includes, arranged in cooperatively associated series relation, storage hopper means (12), heat exchanger means (14), thermal pipe reclaimer means (16) and cyclone scrubber means (18).  The function of the storage hopper means (12) is to store therewithin a suitable supply of grain size material, which is to be treated.  At a preestablished rate the material is fed from the storage hopper means (12) to the heat exchanger means (14).  While traveling through the heat exchanger means (14) the material is preheated to a first temperature.  From the heat exchanger means (14) after undergoing metal separation and crushing of lumps, the material is supplied to the thermal pipe reclaimer means (16) wherein the material is heated to a specified temperature for a predetermined period of time in order to effect the burning away of organic matter which the material embodies.  After leaving the thermal pipe reclaimer means (16) the material travels to the cyclone/scrubber means (18) wherein the surface of the grain size material is cleansed and post reclamation of the material occurs.  The material, which is now at a second temperature, is then again conveyed to the heat exchanger means (14) whereupon during the course of traveling therethrough the material is cooled to a suitable temperature.

Abstract: Abstract of the Disclosure The invention is directed to an arrangement for correcting the position of a laser beam guided by means of an articulated optical system.  This system includes a position-sensitive detector at its output end for generating a signal which is passed to an adjustable mirror arranged on the input end.  The adjustable mirror compensates for an excursion of the laser beam occurring as a result of faults in the guide means and bearings of the articulated arm.  Prior to entering the articulated optical system, the laser beam or parallelly guided pilot beam is modulated with respect to the beam direction with a small amplitude by another adjustable mirror.          The detector signal component corresponding to the modulation frequency is passed to an electronic circuit which determines the directional relationships between the excursion of the laser beam at the output of the articulated arm and the follow-up movement of the adjustable mirror for deflecting the beam.  This determination is achieved independently of the amount of rotation of the rotational bearings.

Abstract: FREQUENCY COMPARATOR CIRCUITS            Abstract A voltage comparator includes two sampled input networks connected in parallel between an input reference voltage and the inverting input of an integrator, the other input of which is grounded.  The first input network has a first input capacitor which is through-switched at a first sampling frequency. The second input network has a second input capacitor which is diagonally-switched at  a second sampling frequency, thus providing an output voltage to the integrator which is of opposite polarity to that of the first network.  For a given ratio between the capacitors, the output of the integrator is determined by the relationship between the sampling frequencies, thus providing a comparator capability.           Also disclosed is a frequency lock loop in which the output of a frequency comparator is filtered of the switching frequencies and utilized as the control voltage for a voltage controlled oscillator.  The output of the oscillator is then coupled to a switching pulse generator which provides the switching pulses to the second input network of the comparator.

Abstract: Abstract In a process for forming vias in integrated circuits, a layer of a first metal is formed on a semiconductor substrate. A layer of a second metal is formed on the first metal layer. The second metal layer is etched in a predetermined via pattern with a second etchant which reacts with the second metal and which is substantially unreactive with the first metal. The first metal layer is then etched with a first etchant which reacts with the first metal and which is substantially unreactive with the second metal or with the semiconductor substrate in order to form a predetermined interconnect pattern having a predetermined contacting relationship with the predetermined via pattern. This process may be used to generate second and subsequent levels of vias and interconnects which can be used to contact metal layers at any level directly to the substrate by building via posts from the substrate to any desired metal layer.
