Title: Real time tracking control for taught path robots
Inventor: HAEFNER KENNETH B
IPC: B25J9/16
Filed: 1986-12-12
Granted: 1991-03-12
Abstract: REAL TIME TRACKING CONTROL   FOR TAUGHT PATH ROBOTS          Abstract of the Disclosure A real time steering capability is provided to permit robot motion to be modified continuously in three dimensions as the robot is moving along a taught path.  An arc welding robot or other taught path robot has a sensor located on the robot arm to sense the position of a desired path.  The tracking control provides real time steering commands to the standard robot taught path and are calculated based on maintaining a constant, preprogrammed velocity along the desired path and coor-dination with the taught path.  Offsets to the robot taught path are computed in a manner that allows the robot to smoothly follow the actual path as measured by the look ahead path sensor.  The offsets are determined as separate x, y, z and twist integrations for the end effector and represent the total deviations from the robot taught path.

Title: Closed loop delivery gauge control in roll casting
Inventor: KNAPP DAVID J
IPC: B22D11/16
Filed: 1986-12-23
Granted: 1991-05-07
Abstract: Abstract of the Disclosure An integrated process for automatically controlling the position of solidification of molten metal in the bite of rotating rolls of roll casting apparatus, the gauge of solid metal exiting the apparatus, and compensation for eccentricity in the rolls of the apparatus.  The process includes a series of measuring steps that provide values indicative of solidification position, exit gauge and the frequency of roll eccentricity.  The solidification position and gauge values are separately compared to reference values established for the position and gauge, with corrections being made respectively to the speed and casting gap of the rolls when differences occur between the measured and reference values.  While such measuring and correcting steps are being performed the measured frequency of eccentricity is being employed to cyclically change the roll gap to offset the effects of eccentricity on the gauge of metal exiting the mill.

Title: Elevator propulsion (or drive) with control device for smooth (or jerk-free) start-up
Inventor: KLINGBEIL KLAUS-JUERGEN
IPC: B66B1/28
Filed: 1988-05-20
Granted: 1991-10-08
Abstract: ABSTRACT:          This control device suppresses the jerk (or jolt) at the start-up of speed controlled elevator installations in both directions of travel, not only the friction jerk (or jolt) at the transition from the static friction (RH) to the sliding friction (RG) but also the imbalance jerk (or jolt) at unbalanced  car load.  For this a nominal value multiplier (39) is connected to the output side of a nominal value transmitter (14) in the drive control; the multiplying factor m (of the multiplier (39) ) can be con trolled by way of an on-/off circuit (46) and the multiplier (91) and is switched, prior to the start of the movement, by the flow control (21) to a value  > 1 and at start of movement in the di-rection of travel by the motion detector (16) again to the value 1.  From this there results for the customary nominal start-up curve (92) an increase of the initial range (?).  By m >1 the monotonically rising correction curve (97) is chosen here in such a way, that with the monotonically dropping correction curve (98) the motor driving power is reduced at the start of the move-ment in synchronism with the friction resistance and an initial sagging respectively jerking up of the elevator car against the direction of travel because of the rapid run-up of the motor driving force is prevented to a great extent. The corresponding actual-start-up curve (99) exhibits in comparison to the custom-ary actual-start-up curve (93) an earlier beginning of the move-ment t3 and has a horizontal start-up tangent (100) and thus jerk (or jolt) free start-up without a transient process (94). This suppression of jerks (or jolts) is eminently suitable for the ulterior fitting of controlled elevator drives and increases, due to the earlier start of movement, their elevating capacity.

Abstract: TELEPHONE SYSTEM FOR CONNECTING A CUSTOMER TO A SUPPLIER OF GOODS                      ABSTRACT OF THE INVENTION           A telephone system automatically connects a potential customer with  a  nearby  dealer who can provide the  goods  or services  desired  by  the  potential  customer.    The  potential customer  first  dials  an  "800"-type  number  which  preferably includes digits uniquely characteristic of the product or service desired.  The system identifies the originating telephone number of the potential customer and a computer initially routes the call to a specific customer dealer service company (CDSC) office in the general vicinity of the potential customer.  The specially equipped CDSC HQ office includes a vertical-horizontal (V-H) file listing  each  dealer  by  product/service  and  equivalent  of longitude/latitude.    A  comparison  is  performed  between  the telephone number of the potential customer and the data in the v-H  file to find 1-3  selected dealers nearby to the potential customer.   The system then automatically dials the telephone number  of the  closest  dealer  thereby  routing  the  potential customer directly to a nearby dealer who can provide the products or  services  of  interest  to that customer.    If  the  dealer's telephone  number is busy or does not answer,  the system can attempt to call another nearby dealer if one exists.  The system also provides for billing the telephone call and for reporting each call in detail to the advertiser.

Abstract: FLOW SENSITIVE SLANT PLATE TYPE COMPRESSOR     WITH VARIABLE DISPLACEMENT MECHANISM            ABSTRACT OF THE DISCLOSURE      A refrigerant compressor including a compressor housing hav-ing a cylinder block is disclosed. A plurality of cylinders are formed around the periphery of the cylinder block and a piston is slidably fitted within each of the cylinders and is reciprocated by a drive mechanism. A crank chamber is formed between the cylinder block and a front end plate of the compressor housing. The drive mecha-nism includes a drive shaft, a rotor disposed on said drive shaft, a slant plate with an adjustable slant angle disposed adjacent the rotor, and a wobble plate disposed adjacent the slant plate. The drive shaft is rotatably supported within the front end plate. Rotation of the drive shaft causes rotation of the rotor and the slant plate, causing nutational motion of the wobble plate to reciprocate the pistons within their cylinders. The compressor housing includes a rear end plate including suction and discharge chambers. An inlet portion of the suction chamber and an outlet portion of the discharge chamber link the compressor with an external fluid circuit. The inlet portion is linked to an external evaporator. A narrowed portion is located between the inlet portion of the suction chamber and a main portion is the suction chamber and creates a pressure difference there-between. A communication path links the crank chamber and the suction chamber and is controlled by a valve control means. When the capacity of the compressor is changed, the valve control means links the crank chamber with the external evaporator via the inlet portion due to the pressure difference created by the narrowed por-tion to reduce the outlet pressure thereof, preventing a decrease in efficiency of the evaporator.
