Granted: 1980-01-15
Abstract: ABSTRACT         The specification describes an apparatus for loading a stillage with elongate articles such as extrusions fed lengthwise of themselves along a conveyor.   The apparatus comprises a horizontal series of spaced forwardly projecting sub-frames each carrying one or more rollers rotatable about a horizontal forwardly extending axis on to which rollers the extrusions can be fed, from the conveyor, the rollers forming effectively an extension of the conveyor.   The sub-frames can be moved forward and rearward relative to the frame of the apparatus, i.e. laterally with respect to the line of movement along the conveyor.   Between adjacent sub-frames are tines which can be raised to lift the extrusions off the rollers and, after the sub-frames and rollers have been moved rearwardly, can be lowered to lower the extrusions on to the stillage.  The tines can then be moved rearward to disengage them from the extrusions on the stillage, either by movement of the tines relative to the main frame or by moving the main frame itself.         Means is provided for depositing spacers on the extrusions whilst they are in their raised position after having been lifted from the rollers by the tines so as to separate those extrusions from the next extrusions to be placed on the stillage.

Abstract: ABSTRACT OF THE DISCLOSURE       A load measuring system for a tandem-wheeled vehicle.  The tandem axles of the vehicle engage opposite ends of two transversely spaced equalizing beams having their mid-points pivotally supporting the vehicle.  Deflections of the equalizing beams and front axle, responsive to loading of the vehicle, are sensed by a load cell transducer mounted on each equalizing beam and on the front axle.  An amplifying circuit receives the transducer outputs and drives a load indicator. The load indicator provides a visual indication of front and rear wheel axle loading with respect to a preset maximum load point.

Abstract: A b s t r a c t A device for indicating the direction to a remote object comprises at least one plate-like unit consisting of a plurality of elongated light guides, arranged in parallel, mechanically interconnected but optically insulated from each other. The end surfaces of the light guide  located in one end surface of the unit face the object and their opposite end surfaces are facing the observer who sees a light area, or spot, composed by light passing through those guides which are right before his eyes. When the light spot is in level with his line of sight to the object the longitudinal axes of the light guides indicate the direction to the object. In a preferred embodiment two units are used one of which is rigidly mounted in a vehicle whereas the other one is pivotable around an axis perpendicular to the longi-tudinal axes and to the end surfaces of the light guides. The pivoting movement is controlled by one or more variables repre-sentative of the spatial situation of the vehicle.

Abstract: Abstract of Disclosure A frequency or speed error circuit for producing a dc. voltage which in polarity and magnitude varies according to the sense and the size of the error between a variable input frequency and a set point frequency. The period of successive cycles of the variable frequency incoming signal is digitally compared with a fixed, predetermined time interval measured off by a precision standard interval generator to produce pulses which vary in width according to the magnitude of the error. The latter pulses are treated as negative or positive when the variable period is shorter or longer than the standard time interval, and are algebraically summed by an operational amplifier having a filter to produce the dc. voltage with a magnitude corresponding to the average of the summed pulses. A deadband is created by optional devices added to the digital comparator. Infinitely fine resolution is achieved by the gating and counter components of the standard time interval generator, thereby to avoid the ambiguity of a measured standard interval possibly being other than an integral multiple of the period of precision frequency clock pulses.

Abstract: ABSTRACT OF THE DISCLOSURE     Steel scrap of known analysis, properly sized, cleaned and heated sufficiently to remove substantially all moisture is thrown through a closed chute in small pieces at a controlled rate and velocity into the ladle simultaneously with the pouring of the molten metal.  The amount of added scrap is  sufficient to lower the temperature of the mixture to that desired for pouring into a mold while being limited to an amount which will melt so as to obtain a homogeneous mixture.  As the scrap is added to the ladle simultaneously with the hot metal, and proportionality thereto, the temperature of the steel is reduced uniformly and overcomes the problem of temperature variations which occur if scrap is added in conventional form.

Abstract: ABSTRACT OF THE DISCLOSURE           A system for use in a building for venting a fire with-in the building.  When a fire starts within a section of a high-rise building, smoke can spread throughout the building, or at least throughout an area of the building, and can cause a panic.   In order to permit the escape of smoke, the practice has been for firemen to break windows of the existing structure in order to vent the fire, thus allowing it to quickly burn out while dissipating the smoke generating from the smouldering fire.          Since the breaking of windows necessarily involves some danger and the clearing of people away from the immediate area before the windows are broken, there is a loss of time before venting can take place.  Further, the breaking of the windows necessi-tates their replacement.  Accordingly, the present invention provides a system for venting a building, the system comprising a first vent disposed at one floor of the building and including a fixed frame, a movable frame adapted to fit within the fixed frame when in a closed position, and panel means for insertion into the movable frame.  The system also comprises means for pivotally securing the movable frame to the fixed frame, means for securing the movable frame to an open position, and latch means for maintaining the movable frame in the closed position.          A first release member is provided for releasing the latch means of the first vent to permit the movable frame to open to its open position.  A second vent is disposed at another floor of the building and includes a fixed frame, a movable frame and a latch means.  A second release member is disposed remote from the second vent for releasing the latch means of the second vent.

Abstract: Abstract A non-skid case for carrying packaged soft drinks and the like is made as a one piece plastic molding and has depressions in the lower surface of its bottom panel which extend only partially through the bottom panel, and are con-figured to capture and retain high friction pads inserted in the depressions.  These cases may be used on conveyor systems, etc. in place of wooden cases without sliding tendencies which are otherwise caused by the self-lubricating characteristics of plastics such as polyethylene.  Alignment of the pads in accordance with the normal disposition of bottles in the case enhances the stability of filled and stacked cases, and since the pad is not retained in a through-hole passing through the bottom panel, local entrapment of syrups, etc., which can lead to organic growth in that region, is avoided.
