Abstract: ABSTRACT OF THE DISCLOSURE         A microprocessor based sequence controller is dis-closed in connection with a soup and beverage vending machine, in which sequences of functions required in the operation of the vending machine are under the control of the micro-processor unit. The microprocessor unit has two separate storage sections, one of which is not alterable and contains the basic program for the vending machine. The other section is alterable and contains adjustable modifications of the basic program. The alterable storage section is modifiable through the use of a separate service module, which is not normally connected with the sequence controller during normal vending operations. In this way, the integrity of the program modifications is assured. The service module is small and inexpensive, includes a minimum number of components, and is readily attachable and detachable from the sequence controller.  The start and stop times of each function of the sequence of functions are independently modifiable, and an interlock is provided to assure against unintentional modification of the start and stop times. In operation, one of a plurality of sequences is selected and the microprocessor starts a sequence of functions by energizing a continuously running timer, the state (or time) of which is continuously compared with each of the stored start and stop times, each of such times being calculated by adding the modification, if any, to the appropriate value of the basic program. When a coincidence is found, a relevance test is executed, so that coincidences which are not relevant to a selected sequence are ignored. The integrity of the stored modifications is automatically checked periodically, and the stored modifications are ignored if the integrity check fails.

Abstract: ABSTRACT OF THE DISCLOSURE           Method and compositions are provided for chemical analysis of an analyte which is a member of a specific binding pair of organic substances consisting of ligand and ligand receptor (antiligand).  The method involves bringing together the following reagents with the analyte in an aqueous assay medium under mild conditions.  The first reagent is a conjugate of a member of the specific binding pair with a chemical entity which provides a means for chemically changing the concentration of a compound which acts as a signal mediator.  The second reagent is the signal mediator precursor.  The third reagent is a conjugate of a member of the specific binding pair with a component of a signal producing system of which system the signal mediator is a member.  The amount of signal which can be detected is affected by the local concentration of the signal mediator.          By bringing the reagents together in the presence of analyte, where the signal mediator concentration changing means is brought together in a microenvironment with the conjugated signal producing system component, localized concentrations of the signal mediator can be created which differ from the gross concentration of the signal mediator in the assay medium.  The degree to which the signal mediator concen-tration changing means is in close proximity to the signal producing means in a microenvironment will affect the observed signal. By appropriate choice of the two conjugates in conjunction with the analyte, the observed signal can be related to the amount of analyte in the medium.  Novel conjugates are provided, as well as combinations of conjuga-tes in specific proportions to substantially optimize the assay sensitivity.  The combinations are provided as kits, where ancillary reagents can also be included, so as to simplify the combination of reagents, as well as provide for more accurate measurements and relative proportions of reagents.

Abstract: ROCKER ARM ASSEMBLY FOR INTERNAL COMBUSTION              ENGINES                 ABSTRACT OF THE DISCLOSURE         A rocker arm assembly for operating an internal combustion engine valve is described.  The rocker arm fulcrum has a load transfer means positioned above it. Interposers are provided which are movable into and out of load transfer means movement blocking position.  In the blocking position, the interposer prevents floating movement of the load transfer means and the fulcrum so that the fulcrum pivot axis is substantially fixed and the rocker arm is pivotable thereabout to transmit motion from its actuator to the valve.  When the interposer is in the non-blocking position, the load transfer means and the fulcrum can float on the fulcrum support in response to movement of the rocker arm by its actuator, so that the rocker arm is inoperative to transmit motion from the actuator to the valve.  In this way, selective operation of the engine valve may be effected.

Abstract: PHD. 78-135.            ABSTRACT:             The invention provides a method for adapting a hearing aid.  First of all a wide-band reference signal is reproduced via a loudspeaker, which signal has a compara-tively low sound level, for example 40 to 50 dB.  The gain of hearing aid is adjusted so that the person wearing it can just hear this reference signal.  Then, in addition to the reference signal, a periodically recurring narrow-band signal is reproduced, which has a duration of at least 70 msecs, and with an interval of at least 150 msecs., and the range of the optimum sound-level of speech is deter-mined for different central frequencies of this narrow-band signal.  The range thus determined is compared with the range of optimum sound-level of speech for persons with normal hearing abilities and subsequently the setting of the hearing aid is corrected so that the sound level experienced as a pleasing sound level of speech by the user of the hearing aid falls within the sound-level range which is pleasing to persons with normal hearing abilities.  The invention relates to an apparatus for carrying out the method.  Compared to known methods for adapting a hearing aid, the method according to the invention is more accurate and yields more reproducible results.
