Abstract: ABSTRACT OF THE DISCLOSURE A film processor having film transport rollers driven by a drive motor, a sensor for generating a signal representative of roller transport speed and a film density detector arrangement that includes a photodetector responsive to the intensity of a light source for generating a reference background level signal against which processed film is compared is characterized by a monitoring arrangement which periodically samples the photodetector output signal and adjusts a reference background level signal in accordance with fluctuations in the output of the scanner arrangement.  To prevent the system from reacting to momentary perturbations in background level a moving weighted averaging technique is employed.  The rate at which the reference background level signal is sampled is determined by the transport roller speed.

Abstract: ABSTRACT OF THE DISCLOSURE         A normally open close switch and a normally open arming switch are connected in series with a closing solenoid operatively coupled with hook apparatus for releasably holding breaker movable contacts in a hooked open position against the closing force of a charged breaker operating mechanism.  An arm actuates the arming switch in response to the movable contacts assuming their hooked open position, such that subsequent actuation of the close switch effects closing solenoid activation of the hook apparatus to release the movable contacts from their hooked open position.  A holding solenoid, wired in shunt with the arming switch, prevents the arm from reactuating the arming switch in the event of sustained actuation of the close switch.

Abstract: IMPROVED LOW TOXIC POLYVINYLCHLORIDE STABILIZERS           ABSTRACT         Liquid antimony organic sulfur-containing compounds are rendered stable at ambient conditions by incorporating an effect-ive amount of an ethoxylated organo phosphate ester.  The stable liquid compositions contribute to the stability of vinyl halide resins.                 BACKGROUND OF THE INVENTION           Antimony organic sulfur-containing compounds are well known as stabilizers for vinyl halide resins to guard against degradation by heat during molding and working of the resin into useful articles.  Prior art patents which disclose such antimony organic sulfur-containing compounds and their utility as stabili-zers include U.S. Pat. Nos. 2,680,726; 2,684,956; 3,340,285; 3,399,220; 3,466,261 and 3,530,158.  In past commercial practice, however, the antimony mercaptides have not been widely used as stabilizers because of various shortcomings including, for example, their propensity to exude from molded or worked PVC plastic stock, cost or lack of other advantages associated with their use which might outweigh such shortcomings.  U.S. Pat. No. 3,887,508 is directed to improvements in the utilization of antimony organic sulfur-containing compounds in combination with metal carboxylates.          As described in U.S. Pat. No. 3,887,508, the utility and efficiency of such antimony compounds are improved in the heat stabilization of vinyl halide resins to an unexpected degree.  It has been observed, however, that such antimony compounds which are normally liquid tend to deteriorate or become unstable upon storage.         The problem is particularly important with respect to antimony tris-isooctyl thioglycolate which has secured NSF approval for use in pipe for potable water.  Antimony tris-isooctyl thio-glycolate is unstable and hydrolyzes on exposure to moisture and

Abstract: Motor Protection Control Circuit Abstract A protection device and circuit for a fluid pump or the like including a motor control relay MS for actuating relay contacts MS-1, MS-2, MS-3 that control the communication of power to a drive motor 10a, and a manual reset motor protection device 24 that de-energizes the control relay in response to sensed malfunctions.  The motor protection device comprises a manual reset motor protector 40 having switch con-tacts 42 connected in series with the motor control relay and a tripping coil 44 which, when energized, opens the switch contacts.  A current shunt path 46 including serially connected pump assembly mounted sensors 48, 50, normally shunts current around the tripping coil and is interrupted in the event of a sensed malfunction, causing the energization of the tripping coil which opens the switch contacts and deenergizes the drive motor.  The switch contacts must be manually reclosed to reactivate the pump as-sembly.  The impedance of the tripping coil and the motor control relay are selected so that should the switch contacts fail to open in response to energiza-tion of the tripping coil, the impedance of the trip-ping coil will reduce the voltage on the control re-lay below its seal-in value, thereby deenergizing the control relay.

Abstract: ABSTRACT OF THE DISCLOSURE      The embodiment switches an address in a prefix register in a CPU of a MP or UP data processing system from one PSA (program save area) to another PSA.  The prefix  address switching changes the control of the CPU from a preferred guest SCP (system control program) to a host SCP.  This switching is done by hardware/ microcode means which is not controllable by user instructions executable on the CPU.  This manner of CPU control switching obtains for a preferred guest SCP (such as MVS/370) operating in relation to a host SCP (such as VM/370) nearly the efficiency of standalone execution on the CPU by a preferred guest SCP that is the same as a standalone version of the guest SCP.
