Abstract: PHN. 9557               10 ABSTRACT             A converter circuit for connecting to an aerial input of an RF-superheterodyne receiver, in which a wanted optical or electrical signal is selected from a number of signals at the input of the converter circuit and converted into an RF-signal, being modulated on a carrier frequency, which corresponds to the tuning frequency of said receiver. To do so automatically the frequency of the local oscilla-tion radiation, being present at the aerial input of the receiver is used for controlling both the selection of the wanted signal at the input of the converter circuit and the frequency conversion of said wanted signal.  The con-verter circuit therefore comprises a frequency search circuit, for measuring the frequency of said local oscilla-tion radiation, said frequency search circuit controlling a signal selector for selecting the wanted signal as well as a modulator for modulating the wanted signal on a carrier frequency, which corresponds to the tuning frequency of the receiver.

Abstract: Abstract:            The operator of a taphole drilling apparatus for blast furnaces per-forms manual changes on the apparatus in its safe position of rest and operation by remote control and automatic latching in hazardous taphole work including drilling and subsequent driving, release, and extraction of a tap bar. The usual guide rail (22) carrying recipro-cably a hammer drill (30) thereon incorporates a remotely openable automatically latching centralizer (42) at its forward end and an extraction carriage (29) on which, after removal of the drill steel (43), an impact sleeve (50) can be manually mounted for being impacted by the hammer drill (30). In one mounting position (Fig 5) of the impact sleeve (50), a latch (57) therein is biased to automatically latch the shank of a tap bar (53) thereto for extraction by impacts. In a 180° counter-turned position the latch (57) will fall aside and the mounted sleeve (50) is used to drive the tap bar while guided by the centralizer (42). The sleeve (50) can then be retracted free-ly from the tap bar (53) and the guide rail (22) freed by unlatching the centralizer (42) from the tap bar (53).

Abstract: ABSTRACT OF THE DISCLOSURE      Photography, particularly rear view projections systems.          The present method is directed towards correction of non-uniform illumination in oblique projection onto rear view screens.  Traditionally, the oblique angle projection results in distortion known as the "Keystone effect" and in non-uniform illumination, namely that portion of the viewing screen nearest the lens receiving a greater portion of the light and that portion of the screen farthest from the lens receiving lesser light.  The present method includes selective illumination of the slide transparency so as to direct more light through that portion of the image  which is to be displayed farthest from the lens and less light upon that portion of the image which is to be displayed nearest the lens.  As a result, there is achieved substantially uniform illumination of the obliquely projected image.

Abstract: Production of Concrete Articles Utilizing Heat-Reclaiming System Abstract of the Disclosure A method of producing concrete articles comprises reclaiming a portion of the heat energy from the kiln atmosphere during the curing of the concrete articles, and then utilizing the reclaimed heat energy to pre-heat mixing water used to form other concrete articles, or to add to boiler feed water used to generate low pressure steam, or both.  In the case where two or more kilns are operated simultaneously at staggered curing cycles, the high temperature kiln atmosphere from the kiln undergoing cool down is intermixed with the low temperature kiln atmosphere from the kiln undergoing heat up thereby reclaiming heat energy from one kiln and using it in the other kiln thereby reducing the total energy consumption required for curing.

Abstract: COAXIAL TAP CONNECTOR     ABSTRACT         The present invention relates to electrical coaxial cable connectors for establishing an electrical tap connection to the inner conductor thereof.  Prior art connectors either require the cable to be cut and spliced or require a continuous radial opening or channel to be formed in the cable.  In either case  these connectors are not easily installed.  The connector of the present invention is easily installed and provides a very secure connection.  The electrical con-nector includes a connector body having a U-shaped alignment cavity configured for snugly receiving a coaxial cable and an elongate con-tact member extending into the cavity from a point disposed along the base thereof.  The contact member is adapted for piercing an intact portion of a coaxial cable received within the alignment cavity for making electrical connection with the central conductor of the cable. A pair of additional contact members extend into the alignment cavity and are adapted for piercing intact portions of the coaxial cable for making electrical connection with the conductive braid encircling the central conductor.

Abstract: ABSTRACT OF THE DISCLOSURE     The coins come within the coil field of an oscillator.          Within a reverse feedback path of the oscillator amplifier, several resistances are arranged, switchable parallel to each other individually or in any desired combination, by switching transistors, each controlled by a program.  This makes the amplification controllable step by step.  The program has a constant-value-storage with a stored standard value for the amplification in which oscillations cease whenever the field coil area is free and a calibrating resistance is connected parallel to the condenser of the oscillator;  For each coin type, two pre-determined standard limit values of amplification are stored in the constant-value-storage, with the oscillations ceasing between them in the presence of an acceptable coin.          Prior to each testing operation, the  program, with calibrating resistance being connected parallel to the condenser increases the amplification step by step until oscillations cease.  The quotient of the thus obtained amplification value and the standard value is multiplied by the two standard limit values of each type of coin, and the product is stored in the read-write-memory as the nominal limit value.  During the coin testing, the amplification is altered step by step from the highest nominal limit value to the next lower, and so on.  A coin acceptance signal is issued whenever the oscillator oscillations do not cease with the higher of the two nominal limit values and do stop with the lower of the two nominal limit values.

Abstract: ABSTRACT OF THE DISCLOSURE      A powdery graft copolymer is obtained by a process characterized in that a graft copolymer latex obtained by graft-polymerizing hard-polymer-giving monomers to an elastic trunk polymer is mixed, after the coagulation of the latex or in the presence of a coagulant, with an organic liquid which is hardly soluble in water and does not dissolve but can wet the graft copolymer, in such a volume ratio that a dispersion wherein water forms a continuous dispersion medium phase and the volume ratio of the organic liquid to the graft polymer is 0.9 to 7.5 is formed, whereby the coagulated graft copolymer is impregnated with the organic liquid and dispersed in water, and then the dispersed copolymer particles are recovered from the water medium.  According to this process, a graft copolymer having excellent powder characteristics such as fluidity and particle size distribution can be obtained by the use of a small quantity of an organic liquid.

Abstract: Abstract:     The invention relates to a color imaging device that suppresses false color signals appearing in an area where the difference of brightnesses is great in the horizontal or vertical direction.  When the correlation between picture elements adjacent in the vertical direction is little and the false signal appears in a boundary area in the vertical direction, the false signal is detected, whereupon a color signal is demodulated by utilizing the correlation between the signals of picture elements in the horizontal direction. On the other hand, when the correlation between picture elements adjacent in the horizontal direction is little and the false signal appears in a boundary area in the horizon-tal direction, the false signal is detected, whereupon a color signal is demodulated by utilizing the correlation between the signals of picture elements in the vertical direction.  As a result, the moire phenomenon attributed to false color signals can be reduced.
