Abstract: ABSTRACT OF THE DISCLOSURE     A working vehicle having right and left traveling members driven by respective hydraulic motors adapted to be selectively operated by control levers linked to corresponding valves to effect traveling and maneuvering the vehicle in-cludes a speed change valve that connects a pair of hydraulic pumps serially with the drive motors to effect high speed operation and individually with a corresponding drive motor to effect low speed operation.  A speed control pedal is resiliently coupled through a mechanical switch mechanism to the speed change valve.  The control  levers are pivotally connected to respective cams in the switch mechanism and there-from to corresponding control valves.  Interaction of the cams with cam followers pivotally linked to the pedal provide the control levers with speed control priority such that a neutral position of both levers inhibits high speed operation despite actuation  of the pedal.  Movement together of both levers out of neutral frees the pedal linkage to permit high speed operation.  However, when the levers are oscillated relative to each other as when turning the vehicle, engagement of the cams and followers inhibits high speed operation which is automatically restored when the levers are moved together to drive the vehicle in a straight line.

Abstract: TITLE    "SMALL LOAD DETECTION BY COMPARISON BETWEEN     INPUT AND OUTPUT PARAMETERS OF AN         INDUCTION HEAT COOKING APPARATUS"                     ABSTRACT       An induction heat cooking apparatus includes an inverter which generates ultrasonic frequency energy for heating a magnetic load by induction, and a small load detection circuit.  The detection circuit includes a comparator which compares the input and output parameters of the inverter and latches a bistable device when the input power is smaller than the output parameter.  The bistable device shuts down the inverter to prevent in-advertently placed small utensil objects from being ex-cessively heated.

Abstract: HYDRAULIC RATE CONTROL SYSTEM FOR SPRAYERS          Abstract of the Disclosure A hydraulic rate control system for maintaining a selected application rate at varying ground speeds.  The application rate is selected through an operator control which permits the operator to dial in the spray tip size, the width of the spray pattern per tip and the desired spray rate in gallons per acre, and this application rate can be changed on the go.  A ground-driven hydraulic oil pump directs its entire flow through a variable orifice, adjusted through manipulation of the operator control, and the oil pressure acts against a balance valve which maintains the pressure of the chemical to be sprayed equal to the oil pressure at the variable orifice.  As the ground speed increases or decreases, the oi1 pressure and thus the chemical pressure increases or decreases accordingly to maintain the selected application rate.

Integrated collector assemblies positioned opposite to the distributors receive and collect the transmis-sion of the distributed radiant energy and through reflection or refraction, transfer radiant energy to a minimum of detec-tion locations to monitor the absence or alteration thereof. A rotating optical scanner and a detector are utilized with a continuous stationary light source to successively monitor specific location-coordinate-related portions of transmitted radiant energy and through electronic circuitry, a signal is developed to disclose, with accuracy, the location of objects within the location region "window", as well as other parameters including object size.  In other embodiments, an apparatus with elements cooperating along two dimensions is capable of yielding three-dimensional object parameter information.

Abstract: ABSTRACT OF THE DISCLOSURE     A peripheral device subsystem enable its peripheral devices to  operate asynchronously with respect to attaches hosts through the use of managed buffers, new multiple data transfer modes, control and error recovery operations.  In a preferred first or buffer mode of operation, all data of each record being transferred can be resident in a buffer before transfer to either a host or device.  For a host to device write transfer, receipt of such a record by the buffer results in the subsystem signaling to the host a completion of a transfer to an addressed device even though the device has received none or only part of the data.  In a second or tape write mode, recording data in a peripheral device, such as a tape recorder, completion of recording is not signaled until after the buffer has transferred the data to the recorder.  In the event allocatable buffer or second insufficient to enable operations in the first or second modes, the subsystem automatically switches to a tape synchronous or third mode of data transfer in which data signals are simultaneously transferred between the buffer and the host and peripheral device.  A host SYNCHRONIZE command synchronizes buffer operations to host operations.  Data to be recorded in a peripheral device and resident in the buffer can be retrieved by a host via a READ BUFFER command.  Errors in the subsystem are reported even when delayed after completion of host operations.  Additional mode controls are also disclosed.

Abstract: BLAST FURNACE CONTROL METHOD               Abstract of the Disclosure The substantially uniform operation of a blast furnace can be achieved by a feedback control scheme wherein the top gas is continuously analyzed and the analyses are stored in a computer.  Periodically, the analyses are averaged and the averages are used in mass and heat balance calculations to compute a high temperature heat value (HTH).          The (HTH) values so computed are stored in the computer and the average of the stored periodic (HTH) values over a preselected period of operation is computed.  The differ-ences between the periodic (HTH) values and the average of the (HTH) values determined for the preselected period of operation are determined and these values are used to determine whether any changes are needed to be made to the temperature and/or moisture content of blast air introduced into the furnace through the furnace tuyeres during sub-sequent periods of operation.

Abstract: Abstract An  optical  connector  for  connecting  photometric analysis  equipment  which  includes  a  transmitting  and receiving light pipe to a material such as flowing blood wherein the blood is not contaminated by the light pipe.          The connector has a flow passage therethrough for connec-tion to the blood flow conduit and a light pipe receiving passage extending at a right angle thereto.  At the inter-section of the passages there is provided an image trans-ferring  window,  and  the  light  pipe  is  arranged  to  be snugly received in the pipe receiving passage in abutment with the window.   The image transferring properties of the window are such  that no optical  distortion occurs as  light  is transmitted  from one  face to the opposite face thereof.  This is accomplished by forming the window of  a  coherent  bundle  of  optical  fibers  of  very  small individual  diameters  in  the order  of  0.003  inches  or less.
