Abstract: ABSTRACT OF THE DISCLOSURE    An apparatus to measure select properties such as color, brightness or gloss, of a moving sheet, is insensitive to flutter in the sheet.  The apparatus comprises a housing to one side of said sheet.  A source is located in the housing; the source is capable of emitting a beam of electromagnetic radiation which is aligned to impinge the sheet.  The radiation is selected such that it is capable of being absorbed and being reflected by the select properties of the sheet.  A collector is also located in the housing; the collector is capable of receiving a portion of the beam reflected from the sheet.  A detector capable of measuring the select properties of the sheet based upon the radiation received by the collector is also provided.  The housing is held at a constant distance from the sheet by a stream of fluid from the housing directed to impinge the sheet in a direction substan-tially perpendicular to the sheet.  A standardization member is to the other side of the sheet.  The standardi-zation member is also held at a constant distance from the sheet by a stream of fluid from the member directed to impinge the sheet along a direction substantially perpendicular to the sheet and in linear alignment with the stream of fluid from the housing.  The standardization member can be a continuously cleaned member or a member with a plurality of standardization surfaces.

Abstract: OUTER SOLE STRUCTURE ATHLETIC SHOE                    ABSTRACT OF THE DISCLOSURE         A general purpose athletic shoe is described in which an outer sole is provided with integrally molded cleats of two different types.  The cleats of the first type are disposed around the periphery of the sole and the cleats of the second type are primarily disposed in the remaining portions of the sole.  The second cleats are generally conical in shape and extend outwardly from the sole to about half the height of the first cleats.  Each of the first cleats has three sur-faces extending outward from a major exterior surface of the outer sole to a flat crown which is parallel to the major ex-terior surface.  Two of the three outwardly extending surfaces of each of the first cleats take the form of essentially flat surfaces oriented generally perpendicular to the major exterior surface and the remaining outwardly extending surface is a par-tial conical surface which tapers so that the first cleats are widest at their junction with the outer sole and narrowest at the crown.  One of the essentially flat surfaces of each of the first cleats is generally transversely oriented with respect to the sole and the other essentially flat surface is aligned with the contour of the adjacent edge of the sole

Abstract: ABSTRACT      Tamper proof apparatus for verification that a critical temperature has been reached or exceeded includes a permanently sealed casing and cap containing a thermal element connected to a rotatable cam having a temperature indicator extending outwardly therefrom adapted to rest under a transparent window in the cap when critical temperature has been reached.  Maximum and minimum temperature stops on the cap prevent movement of the indicator beyond preselected positions.  An opening through the cap engages a removablel shipping pin cooperating with either the maximum or minimum temperature stop to prevent movement of the indicator during shipment or storage.  A locking spring connected to the cap traverses the lateral surface of the cam until the spring engages a shoulder formed in the cam.  The shoulder and spring have, respectively, a first spur and a second spur that engage in permanently locked position when a critical temperature has been reached.          As described heretofore, the cam, spring, and maximum and minimum temperature stops can be arranged, prior to sealing the cap and casing, to indicate that either a maximum or a minimum temperature has been reached.          Another embodiment has two separate spring mounting positions, and two separate cam shoulders, which alternatively can be arranged, prior to sealing, to verify that either a maximum or a minimum has been reached.

Abstract: UNDERCUTTER SEED PLANTER                    Abstract An undercutter seed planter in the form of an elongated tubular seed delivery member adapted to be pulled beneath the soil behind the blade of an undercutter plow.          An air metering system supplies seeds to the seed delivery member and such seeds are released at preselected intervals beneath the soil surface from a discharge opening at the member's trailing end.  The trailing end portion of the member is formed to create a V-shaped channel to receive the discharged seeds, and a gage wheel assembly connected to the member's trailing end rides upon the surface of the soil and maintains the seed discharge opening at a predetermined distance beneath that surface.  A two-way hinge connects the leading end of the seed delivery member to the undercutter plow to permit vertical and horizontal movement of the member's trailing end with respect to the plow.

Abstract: Abstract:     The layout of an open pit mine for tar sands ore facilitates the handling of the ore by employing two or more cuts that diverge from each other while extending away from a common dump adjacent a processing (extraction) plant. Successive parallel and adjacent strips of overburden and ore are removed, whereby each cut is widened and deepened. As a result, each adjacent pair of cuts open to a common track.  Initially, this takes place in the vicinity of the dump, but, as mining proceeds a track (or ramp) is formed that is common to the two cuts while leading from each cut to the dump.  This provision of a common track shortens the haulage routes involved.  The ore is mined with large power shovels and loaded into large trucks, this equipment working down on the ore body.  For stability, a firm surface (roadway) is formed on the ore to support the shovels and trucks.  A major advantage of the system is flexibility of movement between pits and lack of restriction in mining depth and much improved ability to separate ore and reject.  The handling of tailings is also substantially facilitated, and the over-all capital cost of a large scale installation, as well as the operating and maintenance costs, can be expected to be hundreds of millions of dollars cheaper than an installation of the same capacity constructed in the conventional manner.

Abstract: ABSTRACT          MULTIPROCESSING INTERRUPT ARRANGEMENT        There is disclosed an interrupt arrangement for use in a multiprocessing system where it is desired to specifically direct interrupts from one processor to any other processor.  The arrangement treats the interrupt signal as a data communication between processors.  In this regard, common address space is set aside, on a system basis, for interrupt signals.  A sending processor (30) first contends for the system bus (105) and then addresses a message to a specific target processor (20).          The message is received at the target processor over the regular communiction channel and stored in a FIFO memory (22).  Interrupt messages filter through the memory (22) in order of arrival and cause interrupts to occur at the target processor (20).  The information at the output of the FIFO memory (22) controls the processing of the interrupt.

Abstract: :  23  :                    ABSTRACT OF THE DISCLOSURE          A line network communication system transmits coded data signals on a base band carrier signal and includes a receiver capable of recovering the coded data signals from transmitted signals.   The receiver operates in a search mode initially, in which a series of data signals received is compared, at different relative phases, with a series of coded reference signals using an arrangement of shift registers and an exclusive OR gate.        The reference signals are generated by a coder under the command of a central control unit.  The control unit monitors the results of comparisons and varies, by means of a shifter circuit, the relative phase of compared signals until at least one comparison indicates a degree of correlation exceeding a threshold value.   The control unit then operates, in a tracking mode, to verify that said degree of correlation is maintained for a preset number of subsequent comparisons and in dependence  on a successful verification enters a locking mode.   The control unit maintains a selected phase difference between compared series while the degree of correlation exceeding said threshold value exists.
