Title: Plate making attachment for graphic  art cameras
Inventor: KUEHNLE MANFRED R
IPC: G03G15/26
Filed: 1978-05-31
Granted: 1982-10-12
Abstract: ABSTRACT     Plate making attachment for a graphic art camera taking the place of the ordinary silver halide film cartridge back.          The attachment includes an endless belt of flexible electro-photographic film that is charged by a source of corona, exposed, rotated to a location where toner in liquid form is applied to the resulting latent image under bias conditions.     A supply of plate material such as paper, aluminum, plastic or other flexible substrate material is included and a single sheet or a portion of a continuous supply roll is fed into the nip of a pressure roller engaging against the endless belt, transferring the toned image and dispensing it or feeding it past a fixing station and thereafter dispensing the completed plate.  This plate is suitable for use in an offset printing press.

Abstract: PHD. 77-078.   ABSTRACT:       For a true reproduction in colour television display tubes it is of importance to accurately establish whether the distance between the colour selection elec-trode and the display window corresponds to the previously adjusted nominal distance.  Not only variations may occur in the said distance, but variations may also occur in the nominal glass thickness of the display window.  When measured capacitively errors occur in the measured dis-tance as a result of said variations in the glass thick-ness.  These errors are minimized by a method wherein a measuring electrode is positioned on the surface of the display window remote from the colour selection electrode, a screening electrode is positioned on the said surface, which screening electrode surrounds said measuring elec-trode and has an outer dimension such that sufficient electrical field inhomogenities are produced between the colour selection electrode and the measuring electrode, and the capacitance between the measuring electrode and the colour selection electrode is measured by means of an alternating voltage.  In this way variations in the glass thickness up to at most 15% of the nominal thick-ness produce a negligible change in the measured capaci-tance.  For a range of glass thicknesses of the display window and a range of distances between the colour selection electrode and the display window the outside dimensions of the screening electrode are given.  A prac-tical embodiment of a device for carrying out the method is disclosed also.

Abstract: ABSTRACT OF THE DISCLOSURE         A valve including annular valve seats, made of a resilient material such as rubber, fitted in respective valve seat retainers provided in the peripheral portions of fluid passages in the valve body.  A gate is slidingly moved to open or close the valve, with its wall surface being maintained in contact with each valve seat.  Each of said annular valve seats are brought into close contact with the wall of the gate when the gate is moved to a closed position to provide sealing there-between.  In addition, the valve comprises a fluid passage pro-vided in the gate which serves to decrease the pressure of the fluid acting on the valve seat on the upstream side at the initial stage of the movement of the gate from the closed position to the open position, whereby the valve seat is biased from the gate.

Abstract: ABSTRACT OF DISCLOSURE   The present invention is directed to a baler incorporating improved material hold-down means and bale ejecting means. The improve-ment of the invention not only provided material hold-down members which are retractable for bale ejection, but which also assure that the material hold-down members will be retracted before a tied bale can be ejected. In general, the above features are provided in accordance with a preferred embodiment of the invention by mounting on the rear wall of the baler a plurality of pivotally supported and relatively large dog members which normally hang or are suspended in a retracted position The rearward end of each flexible ejecting member is provided with a coupler which is adapted to engage the adjacent dog member when the baler is being used to compact material. The weight of the coupler and the flexible ejecting member is effective to bias the dog member resiliently inwardly into the compacting chamber so that the dog member effectively restrains the compacted material within the chamber. When each ejecting member is uncoupled from the dog member for coupling the ejecting member to the platen, the dog member automatically pivots to its retracted position so that it does not interfere with removing the bale by elevating the ejecting members.

Abstract: FLOW MOMENTUM REVERSING FIRE ABATEMENT SYSTEM                ABSTRACT OF THE DISCLOSURE         Disclosed is an apparatus and method for extinguishing fires consuming combustible fluids, particularly gaseous fluids, issuing from wells, pipes or vent stacks.  The apparatus comprises an extinguisher body typically having a cylindrical passageway which is connected in inline flow relationship with the well, pipe or vent stack and through which the flow of combustible fluid must pass.  A diffuser cone is mounted within the extinguisher body passageway in coaxial alignment, the apex of the cone directed towards the outlet of the extinguisher body.  An extinguisher fluid nozzle is mounted within the extinguisher body passageway for directing a flow of high momentum inert gas against the apex of the conical diffuser.  High momentum inert gas is supplied to the nozzle when it is required to extinguish a fire consuming the combustible fluid passing through the extinguisher body and out of the well, pipe or vent stack. The high momentum flow of inert gas directed against the apex of the cone effectively blocks the flow of the combustible fluid through the extinguisher body while purging the combustible fluid from the extinguisher body to the outlet of the well, pipe or vent stack.          The invention has particular applicability to vent stacks connected to the ullage spaces of tanks containing cryo-genically liquefied combustible fluids such as liquid hydrogen or liquefied natural gas.

The liner is replaceable and greatly increases the wear life of the trough.  The liner reduces drag and wear of the flights or screw and reduces the horsepower require-ments in the conveying of the free-flowing material.

Abstract: CANISTER CLOSURE            ABSTRACT OF THE DISCLOSURE          A closure is provided for canisters, in particular canisters having a relatively large mouth or opening, and designed for keeping foodstuffs in the kitchen.          The canister opening is defined by a sidewall, and the closure comprises a skirt that is radially expandable in a controlled manner for clamping inside of the sidewall, or releasing the sidewall, to seal or open the canister opening.  For the controlled expansion or contraction of the skirt of the closure the skirt is flexibly connected to a convex bottom.  The bottom includes a conical, relatively rigid intermediate ring panel sloping downward-ly towards the interior of the canister from the skirt, and a rigid central panel circumferentially hinged to the intermediate panel and axially movable in a controlled manner for varying the slope of the annular intermediate panel, thus varying the effective diameter of the skirt.          A major advantage of the invention is that the closure is clamped in the canister opening by the closure bottom being changed from more convex to less convex, whereby a subatmospheric pressure is generated in the interior of the canister, which is conducive to retaining the closure in the canister opening.  The bottom is not permitted to become completely flat or become concave.

Abstract: ABSTRACT OF THE DISCLOSURE           Ice-going vessels are composed of a strengthened fore body with ice-breaker prow and an aft body enclosing propulsion machinery.  These portions are designed to be united by way of an intermediate cargo carrying portion, or directly to each other.

Old ships of this design can also easily be converted.  The intermediate portion preferably has such size that a satis-factory volume of arbitrary cargo can be handled at a favourable freight cost.  The breadth and the depth of this portion is suited to those of a big ice-breaker.
