Abstract: METHOD AND APPARATUS FOR REMOVING POLLUTANTS FROM A GASEOUS MIXTURE                         ABSTRACT Method and apparatus for treating of waste gases, such as hot-flue gases, to remove therefrom pollutants in the form of solids, such as fly-ash and the like; and also for the removal of chemical substances present in a gaseous form, such as the oxides of sulphur.  The solid waste materials, such as fly-ash, are removed from the flue gases by mechanical separation, while the gaseous pollutants, such as sulphur dioxide and/or sulphur trioxide are removed by a scrubbing action with another chemical substance carried in a solu-tion and dispersed by spray action.  The polluted gas is preferably first passed through some form of mechanical separator for removal of solids, and is then passed through a sinuous channel, preferably containing a U-shaped chamber, wherein as the gas descends through one leg of said chamber, it is sprayed with the reactive solution to produce a precipitate that descends to the base of the chamber by gravity, and as the gas ascends through the other leg of the chamber, it is again treated with said solution to react and remove as much of the gaseous pollutant as is possible.         By reason of the high temperature of the flue gases, and the control of the flow of the fluids, the precipitate is in a dry and powdery condition, wherein it can be collected either in the treatment chamber, or by subsequent mechanical separation.  The solids either in the form of fly-ash, or the reaction product of the chemical treatment, and particularly the latter, may have commercial value for other purposes.

Abstract: PATENT APPLICATION       For HEAT UNIT INTEGRATOR FOR X-RAY TUBES                  By John T. Perry Joel J. Schmutzer ABSTRACT           Apparatus to indicate the temperature of an X-ray tube target includes an analog storage circuit to simulate the heat energy stored. Input signals representing the current and the voltage of the electron beam in the tube are multiplied to give a signal representing the instantaneous power input.  The power signal is integrated in the storage circuit to give a temperature signal representing the total heat. input.  The temperature signal is dissipated by a cooling curve circuit representing the heat loss with time. An indicator reads the temperature signal.          Input voltage and current signals are processed to refer them to ground before multiplication.  The current signal is corrected to set its zero value.  The voltage signal derived from a transformer primary is corrected for transformer regulation.  To eliminate spurious inputs the power signal is gated to the storage circuit only when a measured current is flowing.  Multiple storage circuits indicating a number of tubes remember the temperature of their own targets while the power signal and the temperature indicator are being used with another storage circuit.

Abstract: ABSTRACT         A method of, and device for, manufacturing semiconductor devices in which a layer of semiconductor material is provided on a main surface of a solid substrate by solidification of molten semiconductor material on the substrate surface. A substantially floating liquid mass of the semiconductor material is formed on a horizontal surface of a solid support and this liquid mass is contacted with a main surface, which surface is wettable by the liquid mass, of the solid substrate onto which the layer of semiconductor material is to be provided. The solid substrate has the form of a strip which is moved in its longitudinal direction along the liquid mass so that a liquid layer of semi-conductor material is formed on the strip and taken along with it. This liquid layer is then progressively solidified.

Abstract: ABSTRACT OF THE DISCLOSURE          A releasable fastening for the ring portion of a tape tab to the body portion of the tab.  The tab is a laminate of plastic and metal and is folded along its longitudinal edge to form a hem which not only increases the tensile strength of the tab and prevents tearing but, also, inverts the plastic, which is normally on the bottom of the tab, along opposite edges to provide plastic strips extending lengthwise of the tab.  The . ring portion is also hemmed and, in being folded onto the body portion, disposes the plastic strips on its edges against the plastic strips on the body portion.  The opposing plastic hem strips are heated and clamped together to produce a fracturable attachment to temporarily hold the ring portion flat against the body portion which lays flat on the end panel.  When the ring portion is pulled up preparatory to peeling the tape off the can end to which it is attached, the attachments fracture and allow the ring portion to be pulled up.

Abstract: METHOD OF RECOVERY OF BITUMEN  FROM TAR SAND FORMATIONS   (D#72,864-F) ABSTRACT OF THE DISCLOSURE         A competent permeable communication zone connecting injection and production wells completed in a tar sand which communication zone will be rigid and will not tend to slump or heal may be developed by injecting a fluid in the injection well under such pressure so as to fracture the tar sand formation between the injection well and the production well and circulating a fluid between the injection and production wells which is at a temperature sufficiently low to freeze the water in tar sands. The fluid may contain propping agents to hold the fracture surfaces apart.  This procedure will rigidify the hydrocarbon portion of the tar sand formation in the vicinity of the fracture zone as well as freeze the water in the tar sand formation.  Once the fracture is established a solvent for the hydrocarbon in the tar sands may be circulated preferably at a temperature below the freezing point of the water in the tar sands to extract the bitumen therefrom.

Abstract: ABSTRACT OF THE DISCLOSURE            A repeating animal trap of the inclined plane type including a collection means defining an enlarged container for confining animals with at least one trap means set in an opening in the wall thereof.  The trap means includes a pivoted floor means and a pivoted door means.  The floor means is normally biased to a first position in which the exit from the trap into the container is totally blocked with the door means in this position being opened at the entrance to the trap so that already confined animals cannot escape through the trap while additional animals can enter the trap.  When an animal enters the trap it tilts the floor means to a second position which simultaneously raises the door means and blocks the entrance while unblocking the exit thereby permitting an animal within the trap means to enter the container while precluding his escape from the trap means.  Confining members in the form of slidable plates can be secured to a side portion of the collection means to direct animals that bypass the trap opening back in the direction of the trap.

Abstract: ABSTRACT OF THE DISCLOSURE          A variable inductance transducer for providing, via inductance modulation, an electrical output signal which is representative of a mechanical input signal.  In a preferred embodiment the mechanical input signal is the intake manifold vacuum of an internal combustion engine and the electrical output signal is utilized in an engine spark timing control system to adjust the spark timing in accordance with the intake manifold vacuum.  The transducer comprises an actuating mechanism in the form of a vacuum servo which axially positions a ferrite core within a central axial bore of a plastic bobbin on which an inductive coil is wound to thereby vary  the inductance of the coil   in accordance with the vacuum applied to the servo.  The bobbin and coil are enclosed in plastic to form a separate unit which is assembled into the transducer by being controllably lodged within the bore of a molded plastic element forming a portion of the body of the transducer.  The transducer is calibrated by the controlled lodging of the unit within the bore of the molded plastic element.
