Abstract: ABSTRACT OF THE DISCLOSURE     A power-driven screwdriver for use with a motor-driven tool for driving a strip of screws one at a time home into a workpiece has an outer guide frame in which a slide block and a slide plate  are slidably mounted.  A screw indexing lever is angularly movably mounted on the slide block and has a pin received in a first cam slot having an oblique portion and defined in the outer guide frame and a second cam slot defined in the slide plate.  When the motor-driven tool is pushed toward a workpiece, the slide block and the slide plate are slid into the outer guide frame, allowing a screwdriver bit to engage and drive a screw into the work-piece.  After the screw has been driven, the motor-driven tool is retracted away from the workpiece, whereupon the slide block and the slide plate are forced to slide out of the outer guide frame under the bias of a spring around the screwdriver bit.  As the pin on the screw indexing lever enters the oblique portion of the first cam, the screw indexing lever is caused to turn feeding a next screw to a position aligned with the screwdriver bit.

Abstract: ABSTRACT     In response to the actuation of a speed control lever by the vehicle operator, a potentiometer puts out a speed setting sig-nal indicative of a desired vehicle speed.  A control circuit res-ponds to this speed setting signal, as well as signals represent-ative of the actual vehicle speed and of the temperature of the retarder fluid, by putting out a first braking signal, correspond-ing to the difference between the desired and actual vehicle speeds and a second braking signal corresponding to the difference between the actual acceleration of the vehicle and a preset acceleration.          Under the control of the control circuit a selector normally passes the first braking signal and, when either the temperature of the retarder fluid or its temperature rise gradient exceeds a preset maximum, the second braking signal.  The first or second braking signal is proportionately translated into a hydraulic pressure for actuation of a retarder.  The second braking signal is intended to prevent the overheating of the retarder as when the vehicle is traveling down a long or steep slope.

Abstract: ABSTRACT           Apparatus for transferring paper stacks from a first horizontal path into a second horizontal path which is coplanar with the first path has tongs installed at the junction of the two paths and driven to rotate about a vertical axis.  The tongs has a lower jaw in the common plane of the two paths and an axially movable upper jaw which is held away from the first jaw when a stack to be transferred approaches the tongs and which is then moved toward the lower jaw to clamp the oncoming stack so that the latter rotates with the jaws and is transferred into the second path.  The tongs then opens and is ready to engage the next stack. Signals for closing and opening of the tongs are generated by first and second detectors which are respectively adjacent to the first and second paths and respectively serve to detect certain surfaces of oncoming stacks and certain surfaces of transferred stacks.  The starting or upper end position of the axially movable jaw can be adjusted by a feed screw by raising or lowering a pneumatic motor which serves to close and open the tongs.

Abstract: ABSTRACT     A count mechanism for a dispensing machine which delivers coins in a single file along a track has a star wheel in the path of travel of the coins.  The star wheel is indexed one point for each coin which passes it.  The star wheel can be positively halted against rotation by a latch which engages a point on the wheel and which is held disen-gaged by a first solenoid.  A second solenoid assists in disengaging the latch from the star wheel.  A spring biased pawl rides the periphery of the star wheel between points to prevent free rotation.  The star wheel is provided with spaced reflective areas on its top surface and a pair of spaced optical sensors detect the presence and absence of re-flective surfaces as the reflective areas pass beneath the sensors.  The optical sensors generate a pair of out-of-phase pulses which are employed to count the coins.  An apparatus and method are also disclosed to test for dirty conditions of the star wheel or optical sensors by comparing logic signals produced in two logic levels.

Abstract: A process and associated apparatus for the cooling of hot fluidized solid particles. The particles flow from a dense phase fluidized bed into the shell side of a vertically oriented shell and tube heat exchanger where cooling occurs via indirect heat exchange with a cooling media circulating in the tubes. The extent of cooling is controlled by operating the cooling zone dense phase with sufficient backmixing to control the heat exchange coefficient between the heat exchange means inserted in the cooling zone and the dense phase fluidized bed. The coefficient is varied by varying a combination of the variables comprising the quantity of fluidizing gas to the fluidized bed in the heat exchanger and the quantity of particle flow through that bed. The process has particular applicability to a combination regeneration process and most particular applicability to the FCC process.

Abstract: Abstract of the disclosure An instrumentation system for use in measuring and processing industrial  process  variables,  such  as  flow,  pressure,  or temperature, includes a resonant element sensor whose reso-nant  frequency  varies  in  accordance  with  changes  in  the desired process  variable  communicating  through  an optical fiber link to a distant control room.   The sensor is acti-vated into resonant physical motion by light energy from a source in the control room, while the motion of the wire is sensed optically and retransmitted to the control room to produce an output signal whose frequency is equal to that of the resonating element.   A feedback network  maintains the sensor in resonance by synchronizing the delivery of light energy to the motion of the resonant element.  The powering and sensing aspect may be performed by individual fiber optic cables  or alternatively this  function may be combined  by utilizing a single fiber optic strand.

Abstract: Abstract of the Disclosure:         In a TDMA network wherein a central station sends signals towards satellite stations in downward frames (A), each comprising a control time slot (TdO) and speech time slots (Tdl to TdM), and receives signals from one to M satellite stations in upward frames (C) of a like format, the central station checks the number of idle time slots in each of the downward and upward frames.          Only when the number exceeds a preselected number, one of the idle time slots i5 selected as an adjustment time slot.  The ordinary number given to the adjustment time slot is transmitted in a number field (Nf) of the downward control time slot.  Each satellite station generates a time axis indicative of local time slots (D) with a delay relative to the thereby received downward time slots (B).  On adjusting the time axis in a seiected satellite station, the station sends a short burst (ts) in the local time slot indicated by the received number field.  In compliance with an error with which the burst reaches the central station, the delay is rendered equal to a prescribed frame delay (te) minus twice a propagation delay (td) between that satellite station and the central station.

Abstract: ABSTRACT OF THE DISCLOSURE           An improved lift-off process for forming metal-lized interconnections between various regions on a semi-conductor device relies on the use of a particular polyimide in forming a protective mask over the device.  The polyimide is a copolymer of an aromatic cycloaliphatic diamine and a dianhydride which allows the resulting structure to with-stand particularly high temperatures in the fabrication process.  In particular, the polyimide when subjected to high temperature metallization under vacuum remains suffi-ciently soluble to be substantially completely removed from the device by immersion in common organic solvents.  This allows high temperature metallization as interconnects for integrated circuits.
