Abstract: The arch wire of an orthodontic appliance is received in the channel of a bracket fixed to each of a patient's teeth to be repositioned. Each bracket includes a holder in which is removably located a selected one of a set of channel members, the channels of which are differently inclined to provide a selection of different force vectors to be introduced by the arch wire on the teeth. The holder is separable from the bracket base and is movable relative thereto to permit tipping the arch wire channel and changing its related height between the gingival and occlusal ends of the tooth, and means are provided which releaseably lock the holder in an adjusted position to the bracket base.

Abstract: A totalizer receives output pulses from two different meters and records them on a single data channel of a magnetic recorder. First and second memories are used alternately in successive demand intervals to store the outputs from both meters irrespective of which meter measured an event. For recording, contents of the respective memories are shifted out in alternate demand intervals. Demand interval timing signals are delayed and recorded in synchronism with the data so that the accuracy of recording is .+-. one event pulse per demand interval. Each memory acts as a summing register for both meters. Thus, the proportion of available storage allocated to each meter is varied according to the respective activity levels of the meters up to the maximum capacity of the recorder.

Abstract: The method of making elongated heat exchangers having outwardly projecting fins spaced longitudinally thereof, wherein the fins are cut or gouged from a work-piece while the work-piece and cutting tool are vibrated relative to each other to afford roughened surfaces on both faces of the fins facing longitudinally of the heat exchanger.

Abstract: Dust generated in coal mining is removed by means of a blower having an exhaust fan which draws air through its intake opening from the face of the coal. The blower is provided with a first stage of closely-arranged small-diametered cylindrical-shaped individual centrifuges between its intake opening and the exhaust fan in which the dust-laden air spins as air is drawn therethrough and concentrates the dust in an annular surrounding portion which is separately drawn from the centrifuges through a conduit also evacuated by the exhaust fan. This conduit contains a sharply-reversing bend which effectively separates and discharges the dust into a collection chamber, e.g. a removable bin. A grid disposed ahead of the first stage of individual centrifuges prevents large size particles from entering the centrifuges; and a second stage of closely-arranged, similarly-operating individual centrifuges located in the conduit closer to the exhaust fan remove "fines" which were not discharged to the collection chamber.

As many of the panels may be connected as are desired; and they may be placed in any desired configuration. Each panel includes an insert assembly to provide its exterior face; and these may be removed and changed, if desired. A full line of shelving and cabinets may be assembled to the panels with a limited number of interchangeable components. The cabinets include a flipper door which will not rack when opened or closed, and which slides beneath the top of the cabinet in the open position, yet has its edges flush with the top and bottom of the cabinet in the closed position.

Abstract: A cold forged cylinder reel tooth adapted to be mounted to the cylinder of a threshing mechanism includes a threshing portion, a tapered seating portion and a fastening portion. The threshing portion includes identical symmetrical double-edged surface blades which are reversable to provide that the opposite unworn edged blade is positioned to engage the grain when the first edge blade is worn beyond practical use. The tapered seating portion permits proper indexing of the reel tooth 180 degrees to permit the unworn opposite double edge surface to engage the incoming grain in the threshing mechanism and the fastening portion provides rapid mounting and demounting of the cylinder reel tooth from the cylinder during the indexing operation.

Abstract: A heat exchanger and method of making same, wherein elongated passageways are formed in unbonded portions of a blank made of bonded sheet material, and integral fins are formed on the sheet material with the fins having elongated base portions extending transversely to the length of said passageways. In certain embodiments the finned portions of the heat exchanger are so disposed relative to each other that fins therein project toward the adjacent finned portions.

Abstract: A demand recorder includes a microprocessor for receiving data pulses representative of measured events and formats the incoming data into demand intervals. After a predetermined number of demand intervals, called a collection period, the microprocessor transfers the data for more permanent storage to a solid state memory which may be removed for remote processing. The system has battery carryover during a power outage, but the microprocessor prevents data transfers to the solid state memory. At the end of a collection period in which a power outage occurred, the microprocessor transfers the current data to a secondary portion of random access memory. For subsequent demand intervals until power is restored and including any thermal recovery periods, the processor formats event data by assigning index numbers for demand intervals in order of occurrence and stores data only for those demand intervals in which power consumption was actually measured.
