A vertical upper inlet duct adapted to be connected to an upper section of a downspout or conductor leads downward through the upper wall of an open-ended horizontal box-shaped housing with a tapered bottom wall converging to a downwardly-tapered vertical outlet duct. The latter connects with a lower section of the downspout or conductor. A screen or grating is inserted in the box-shaped housing over the outlet therefrom, which may be cleaned of leaves or other water-borne trash collecting there...

A watt-hour meter or other visual read-out apparatus which may also be read electrically through the use of a plurality of code discs and a photoelectric sensing device in spaced juxtaposition with the back sides of the discs. The sensing device is supported by a cable-controlled carriage which reciprocates back and forth in a direction parallel to the discs under the control of a bidirectional electric motor. A pair of stop members are located at opposite ends of the path of travel of the carri...

A container has a tear-out portion below which an upper end of a funnel within the container is suspended by a readily frangible connection so that when the tear-out portion is removed from the container, the funnel may be positioned in the opening thereby formed and separated from the tear-out portion. The funnel has external projections for snap-action, sealing engagement with the edge of the opening, a peripheral projection for abutment with the underside of the container top around the openi...

The drop out compensation system comprising input means for accepting a colour or monochrome picture information signal, output means, a drop out compensating signal generator, switch means for effecting connection of said input means to said compensating signal generator and for effecting connection between said compensating signal generator and said output means, and a drop out detector for effecting switching of said switch means, said compensating signal generator including delay means for p...

A check-out terminal wherein coded data identifying articles being checked out is carried past an optical code reading system at a substantially constant distance away includes a tilted main conveyor belt and at least two subsidiary conveyor belts arranged along a longitudinal side edge of the main conveyor belt in a manner such that the major surface of each of the subsidiary belts is substantially at right angles to the major surface of the main belt. The subsidiary belts are arranged so that ...

Two laterally and directionally adjustable supports for shoring and rolling out a formwork intact for reuse in successively pouring concrete floor slabs in a multi-story building. Lateral adjustment includes extension brackets having bases mounted on structural columns each carrying a horizontal angle arm that defines a vertical weight-bearing flange and a lateral horizontal clamping flange. Horizontally adjustable support brackets rest on the vertical flanges and have clamping means engaging th...

A drop-out compensating circuit has an input circuit receiving an angularly modulated input signal, such as, a frequency modulated video signal reproduced from a magnetic tape or other recording media, and supplying such angularly modulated input signal to an output circuit by way of an interposed variable impedance circuit having its impedance controlled in accordance with the amplitude of the angularly modulated input signal, and a complementary signal source is connected to a junction between...

A clipping knife for cutting out clippings from a sheet of paper has a knife blade having a ledge-like or skid-like contact surface for sliding contact with a surface of the paper and a cutting edge disposed in the vicinity of the contact surface and extending beyond it by a cutting depth distance corresponding to the thickness of the paper, whereby the cutting edge is limited by the sliding contact to cut the paper only to a depth substantially equal to its thickness, and whereby the underlying...

A material reducer for coal, lignite, ore, stone, rock, oil shale and the like which employs rotary hammers, bars or the like not only to crush the material but also to propel the crushed material upwardly along a confined or partially confined path which discharges for example onto an output conveyor or directly to a screen or other processing equipment. The feed-in or input end of the crusher can be at a level sufficiently low to be supplied by the newer more mobile loading units such as front...

A blowout preventer for sealing off around a flexible line to prevent hazardous leakage of well fluids, which is held in an open position by control fluid pressure actuated means and moved to closed position upon reduction or release of control fluid pressure. A plurality of segmental metallic closure members have resilient seals for engaging the flexible line without damaging it. Fluid pressure control means is provided responsive to fluid pressure conditions within the blowout preventer for co...
