Abstract: ABSTRACT OF THE DISCLOSURE         A method and apparatus are disclosed for preparing a feed mixture comprising several components in a single stage prior to feeding it into a smelting furnace.  The preparation of the batch may include the preheating and drying of the material, the removal of crystal waters and evaporable substances as well as the conduction of the batch into the smelting furnace.  According to the invention, a hot inert gas is conducted through a downwardly settling batch so that the gas is mixed into the batch as well as possible and even partial fluidization is prevented.  The apparatus of the invention comprises a pretreatment silo which is uniform at the upper part but is divided into several sub-silos at the lower part.  The sub-silos are connected at their bottoms to ducts along which the batch flows into the smelting furnace located below the pre-treatment silo.  In between the sub-silos there is located a gas distribution chamber from which the gases are distri-buted through distribution ducts communicating with the sub-silos, the gases being discharged at the top of the silo. The employed gas is obtained by burning the exhaust gases from the smelting furnace and by combining them with cleaned circulation gases.

Abstract: ABSTRACT OF THE DISCLOSURE           Method for passively determining the range to a target from a test platform.  The method comprises travelling at a constant velocity a course in the test platform which is straight; detecting at the platform the presence of an energy signal radiating from the target, and sampling said energy signal at three discrete times.          Generating for each of said energy signal samples a first detection signal responsive to its angle of arrival at the platform, and a second detection signal responsive to its frequency on arrival at the platform; and storing said detection signals.  The range to the target is then determined utilizing the stored detection signals and the test platform velocity and position; then generating a target indication signal representative of the range of the target.

Abstract: ABSTRACT OF THE DISCLOSURE           In order to meet the energy demand for the lighting and heating of a room (2) in a building (1), windows (4) and non-transparent wall elements (3) of the outer wall are designed so that their heat transfer coefficients (kF, kw) are below 1 W/m2.K.  Electric lighting fixtures (7) and heaters (8) which have at least approximately equal power ratings are used for lighting and heating.  Due to the heat transfer coefficient values as specified above, it is possible to avoid cold air subsidence at the windows (4) and draughts; thus, a relatively small amount of energy supplied through the lighting units (7) and/or the heating units (8) is sufficient for meeting the requirements.

Abstract: METHOD OF MAKING MEMBRANES FOR GAS SEPARATION          AND THE COMPOSITE MEMBRANES                          Abstract Composite membranes suitable for separating gas mixtures are made by in situ crosslinking of aminoorgano-functional polysiloxane, 1 to 9 mol percent aminosiloxane units, with diisocyanate on the surface of a highly porous polymer substrate, such as polysulfone.  Using the crosslinked polysiloxane as a gutter layer, a gas separating entity can be coated on the gutter layer to make a double layer composite membrane which has a higher separation factor than the crosslinked polysiloxane and can be used effectively for flat sheet membranes, as well as, hollow fiber membranes.

Abstract: ABSTRACT OF THE DISCLOSURE         A tamper indicating closure including a transpar-ent outer cap and an inner insert disc with an integral depending plug seal which relies on the relative movement of the outer cap and the inner disc during opening movement to indicate tampering of the container after it has been sealed for the first time. The relative movement is insured by the fact that the plug seal coacts with the container to resist rotation of the insert disc maintaining the container in a sealed condition while the outer cap is being rotated in an opening direction.  The inside top surface of the clear outer cap is printed with a message such as "OK" or "SECURE" in an ink which is removable by a wiping action.  The upper surface of the disc has ridges or wipers which remove all or part of the message upon initial opening.  During the initial application of the closure to the container, fric-tion between the plug seal and the container keeps the outer cap and insert disc together through cooperating lugs as the closure is screwed onto the bottle so that the message is undisturbed.

Abstract: ABSTRACT OF THE DISCLOSURE        Disclosed herein is an exposure intensity detecting system suitable for use in a copying machine.          The detecting system is characterized in that a light-shielding plate is arranged underneath a glass table for an original document and defining there-through a projection slit and a detection slit which extends in parallel with the projection slit.  The intensity of light passed through the detection slit of the light-shielding plate is detected by a photosensor.          The detecting system can correctly detect the intensity of light, which is to be used for the exposure of a photosensitive member, without giving any influence to the distribution of light to be employed for the illumination of the original document and to the exposure of the photosensitive member.  By controlling the quantity of light to be radiated from a light-source lamp in accordance with detection signals of the photosensor, it is always possible to achieve good exposure and hence to form superb duplicate marks.

Abstract: Fuel Injection Solonoid Driver Circuit Abstract of the Disclosure A fuel injection solenoid driver circuit controllably connects and disconnects a solenoid coil to and from a storage capacitor to effect operation of the coil.  Precise control of the timing and duration of coil is necessary to ensure that a proper quantity of fuel is delivered to each cylinder of an internal combustion engine.  A means monitors the voltage level of the storage capacitor and periodically delivers a high voltage inductive spike to the capacitor to maintain the capacitor voltage level within presribed limitations.  Further, a means aids in charging the capacitor by discharging the solenoid coil to the capacitor in response to the coil and capacitor being disconnected.  Use of the energy stored in the coil to recharge the capacitor increases the power efficiency of the circuit and also results in a fast decay of the solenoid voltage.  The fast decay time minimizes variations in solenoid operation timing and duration and precisely controls the quantity of fuel delivered.

Abstract: AVALANCHE PHOTODIODE AND A    METHOD OF MAKING SAME Abstract of the Disclosure The invention is an improved avalanche photodiode having reduced electrical noise arising from spurious surface generation of charge carriers.  The avalanche photodiode includes active and neighboring regions adjacent a first surface of a semiconductor body with a gap region therebetween and a channel extending a distance into the semiconductor body from a portion of the second opposed surface opposite the gap region.  A P-N junction is formed between regions of opposite conductivity type including a portion thereof over the channel.  Since the dopant concentration at the junction is less over the channel, the local avalanche gain over the channel is less, thereby reducing the noise contribution from carriers generated in the gap region.
