Abstract: G-356  C-3,974 BLIND ASSEMBLY OF PARKING BRAKE CABLE TO PARKING-BRAKE LEVER ABSTRACT OF THE DISCLOSURE:       A drum brake assembly having a parking brake actuating lever is so arranged that the parking brake cable end may be assembled in a blind fashion to the end of the actuating lever.  The cable is provided with an enlarged end or button.  The cable and spring are inserted through a guide tube and pushed inwardly into the brake assembly with the guide tube or a combination of the guide tube in a separate spring guide placing the cable button in a alignment so that it is aimed at a funnel-like guide and retention member formed on the end of the parking brake actuating lever.  Further axial movement of the parking brake cable and its enlarged end result in a camming action which moves the enlarged end upwardly through and beyond the slot after which it snaps back downwardly to be positioned to be able to apply cable tension forces to the parking brake actuating lever.  The entire assembly may be made with the brake assembly in the completely assembled condition wherein the drum covers the brake mechanism so that the assembler, operator cannot either see or manipulate that cable end and the connection thereof with the end of the actuating lever.  The arrangement also provides for sealing the opening in the drum brake backing plate through which the parking brake cable extends, and permits checking for full connection of the parking brake cable with the actuating lever before such assembly is completed.

Abstract: ABSTRACT OF THE DISCLOSURE          A continuously variable transmission for a motor vehicle has a closed hydraulic circuit disposed between a hydraulic pump and a hydraulic motor with the hydraulic motor being of the variable displacement type.  The hydraulic pump is driven by the engine and the hydraulic motor is driven by the hydraulic pressure from the hydraulic pump for driving the road wheels.  A pair of bypass passages are connected between the two oil passages of the closed hydraulic circuit between the hydraulic pump and hydraulic motor and a clutch valve is disposed in each bypass passage for adjusting the opening of that bypass passage.  The opening of the bypass passages corresponding to the amount of operation of the clutch valves when the transmission receives driving forces from the road wheels during deceleration is controlled so as to be greater than the opening of the bypass passages when the transmission is driven by the engine to drive the road wheels.

Abstract: FLUORESCENT INDICATOR dyes for CALCIUM               WORKING AT LONG WAVELENGTHS         ABSTRACT The present invention discloses a new class of calcium specific fluorescent indicator dyes having visible excitation and emission wavelengths.  The new fluorescent indicator dyes combine at least one tricyclic chromophore with a tetracarboxylate parent CA2+ chelating compound having the octacoordinate pattern of liganding groups characteristic of BAPTA to give a rhodamine-like or fluorescein-like fluorophore. Binding of calcium2+ increases the fluorescence of the new compounds by up to 40-fold.  The caicium2+ dissociation constants are in the range 0.37-2.3 microM, 60 that the new indicators give better resolution of high [CA2+] levels than were previously obtainable with predecessor compounds such as quin-2 or fluo-2.  The visible excitation wavelengths of the new compounds are more convenient for fluorescent microscopy and flow cytometry than the UV required by previous indicators.

Abstract: ABSTRACT OF THE INVENTION            Each user of an intercommunication bus is associated with a distinct channel of an arbitration bus and maintains a priority record indicating its current priority status against each other user.   During a contention interval each user then seeking to use the intercommunication  bus  bids  for  use  of  it  by transmitting  a  bus  request  signal  and  makes  an analysis of the signals to ascertain if it has a dominating priority for initiating a transaction on the bus, and access is granted accordingly.   During the  use-signal  interval  a  user  then  using  the intercommunication  bus  transmits  an  in-use  signal used to update priority records with the effect of giving the last using user lowest priority.   For transactions which require a response form a user other than  the  one  initiating the transaction,  a second round of bidding is conducted to determine whether any user is qualified to respond and if so which will be enabled to do so. When the response bidding  shows  no  bidders  the  system  immediately initiates bidding for a new transaction.

Abstract: ABSTRACT     A microprocessorized thermal protection system and accompanying method measures input voltage and current of an induction motor and derives therefrom continuously updated estimates of the slip dependent rotor resistance during acceleration of the motor.  The measurements and calculations of the varying rotor resistance enable determination of the heat generated within the motor based on a thermal model thereof. Phase shift distortions induced by the measurement system are accounted for by determining the value of the stator resistance at start up.  In addition, during a brief period following start up, sampling of the voltage/current inputs is suspended to avoid the effects of the initially occurring DC-offset resulting from the application of the voltage input to the inductive motor load.
