Abstract: PROGRAM CODE FETCH ARRANGEMENT   ABSTRACT OF THE DISCLOSURE The present invention permits any number of pages of data memory to contain program code without the loss of access to the corresponding page of the program code memory.  The memory select lead derived from a central processor's control leads is employed by the memory decoding circuitry to distinguish between a program code and a data fetch.  This arrangement forces the memory to produce a code fetch from data space of memory, when any one of the pages dedicated to program code is accessed.  A fetch control circuit is included between the central processing unit and memory.  This fetch circuit obtains program code from the data space in memory when a latch of an input/output port controlled by the central processor unit is set, indicating that a program request is to come from data memory and one of the pages of memory containing program code in the data space is referenced  As a result, the memory decoding circuitry detects this request for a fetch as a data fetch, although the processor indicated the fetch as a program code fetch.  If the input/output port is not set by the CPU to force a program fetch from data space in memory, program code from the program code memory will be fetched.

Abstract: ABSTRACT OF THE DISCLOSURE     A collector member for the vacuum hose lines and pulsator lines from the milking cups of an automatic milking machine is provided which permits connection of the vacuum hose lines to a milk line or milk pail such that milk never contacts any part of the collector member itself. The collector is advantageously used in a system in which the vacuum hose lines from the milking cups are attached to a multi-lumen milk hose with each hose line being connected to a respective lumen in the multi-lumen milk hose. The collector member is sufficiently weighted so as to provide desirable tension to the teats of the animal being milked. The collector provides a means for terminating the vacuum in the respective vacuum hose lines when the milking cups to which they are attached drop from the teat of the animal being milked. The vacuum terminating means comprises an elongate blunt element positioned adjacent to the hose lines as they emerge from the collector member such that when a milking cup falls from its respective teat on the animal being milked, the hose line on the fallen milk cup folds over the elongate blunt element to close the hose line. The collector advantageously allows the use of vacuum hoses made of silicone rubber which have useful lives some seven (7) times that of conventional rubber hose lines. Use of silicone rubber and elimination of milk contact with the collector member further greatly reduces bacteri-ological contamination which can cause mastitis in the animals being milked.

Abstract: OPTICAL FIRE OR EXPLOSION DETECTION SYSTEM AND METHOD      Abstract of the Disclosure There is disclosed a fire and explosion detection system and method comprising at least one first channel including a photocell and accompanying electronics for converting incident radiant energy of a first narrow band of wavelengths into a first electric signal; and, at least one type of second channel means including a photocell and accompanying electronics for producing a second electrical signal proportional to incident radiant energy of a second narrow band of wavelengths correspond-ing to background, black body emissions.  The signal outputs of these two channels are further processed by a ratio detection circuit which produces yet another output electrical signal when the ratio of the two input signals exceeds a predetermined number.  The output of this ratio detection circuit is further processed by a so called flicker frequency detection circuit which counts pulses indicative of the flicker frequency of the fire and gives a first warning if that flicker frequency exceeds a predetermined number.  Additional circuit means process the output of the ratio detection circuit to determine if that signal exceeds a predetermine magnitude to indicate the presence of an explosion or flash fire.  An overload protection circuit is included to inhibit the alarm function of the invention in the situation where the detector is first exposed to sunlight, incandescent light, etc. having characteristic emissions in the band widths of the two photocells.  Representative wavelengths for the two channels are described.  In particular, the black body emission channel is set at 3.8 microns while the other channel is set at 4.3 microns.
