Abstract: ABSTRACT OF THE DISCLOSURE:          An  electrolytic  cell  includes  a cylindrical electrolytic cell main body divided into a main electrode chamber and an auxiliary electrode chamber by a diaphragm. Main electrode particles in the main electrode chamber are maintained in the fluidized state by an electrolyte supplied to the main electrode chamber.  An electrolyte supply port and an electrolyte discharge port are provided to enable this electrolyte to flow through the cell to maintain the fluidized state of the particles.   A porous auxiliary electrode is also provided in contact with the side of the diaphragm facing the auxiliary electrode chamber.  This facilitates flow of gas generated on the auxiliary electrode in the direction of the auxiliary chamber.

Abstract: ABSTRACT OF THE DISCLOSURE A process for removing caffeine and substances that are potentially detrimental to health from coffee.          This invention relates to a process for removing caffeine and substances that are potentially detrimental to health from green coffee, which comprises subjecting the green coffee in the form of beans or in reduced form to extraction, using an organic solvent having a boiling point under atmospheric pressure of not more than 150°C and water, in such a way that after equilibrium has been reached or substantially reached between the coffee and the external phase of the extraction liquid this external phase is homogeneous, subjecting the thus treated coffeee to a steam treatment, drying and optionally roasting the same.        In order to remove substances that are potentially detrimental to health from the coffee, this invention is characterized in that extraction is carried out by co-using an acid in an amount sufficient to remove chlorogenic compounds from the coffee.

Abstract: "DISK BLADE SCRAPER"                    Abstract of the Invention The present invention provides a scraper mechanism for a disk blade including a wear ring attached to the rim of a rotary scraper and releasably biased toward and held in planar contact with one side of a disk blade.  The wear ring is molded from a low friction, long-wearing material, such as molded nylon.  The low friction material eliminates the metal to metal contact of conventional rotary scrapers and therefore eliminates the squeal associated with rotary scrapers.  Also, wear of the scraper is audibly detected when the wear ring is worn away, thereby alerting the operator that maintenance is required.

Abstract: ABSTRACT OF THE DISCLOSURE     Heretofore, there have been two common systems of strip binding.  One uses paper punched with rectangular holes and curled plastic combs having fingers passing through the holes.  The other uses round holes in the paper and male and female strips, the studs of the male strips fitting through the holes in the paper and in the female strips.  Excess stud length is cut off and rivet heads formed to make a permanent bind. The present invention uses rectangular punched paper similar to the first systems and strips generally similar to the second system.  At least two studs and female strip holes are offset to prevent lateral displacement of the paper.

Abstract: ABSTRACT     A cylinder block structure of a light alloy for use in a multicylinder internal combustion engine includes a cylinder-defining portion having a plurality of cylinder bores with a water jacket defined in surrounding relation to the cylinder bores, and a crankcase-defining portion integrally formed with the cylinder-defining portion and having a plurality of integral journal walls spaced in the direction in which the cylinder bores are arranged.          Concavities are defined in opposite sides of the cylinder- and crankcase-defining portions between the adjacent cylinder bores, the concavities lying between the water jacket and journal walls.          A plurality of reinforcing rib systems project from the opposite sides of the cylinder block and each rib system surrounds one of the concavities.  The concavities reduce the amount of molten metal to be poured in casting the cylinder block structure, for thereby preventing casting defects such as cavities from being produced in the cylinder block.  The reinforcing rib systems serve to provide the required degree of stiffness to the cylinder block.  Since the reinforcing rib  systems terminate short of the deck of the cylinder block, no vibration is transmitted through the reinforcing rib sys-tems to the deck, whereby the deck is prevented from being subject to deflecting vibration.

Abstract: APPARATUS AND METHOD FOR DETERMINING         A LIKELY WORD SEQUENCE FROM LABELS GENERATED BY AN AN ACOUSTIC PROCESSOR               ABSTRACT OF THE DISCLOSURE            The present invention addresses the problem of  deter-mining,  in a speech recognition context, a likely se-quence or path of words from a plurality of word paths given a string of labels that are generated at succes-sive intervals.  The invention features multiple stack decoding and a unique strategy for extending one word path at  a time without undue reliance on word path length. With multiple stack decoding, a stack is asso-ciated with each label of the label string. Word paths that most likely end at a given label are assigned to the stack corresponding to the given label and are or-dered according to likelihood at the given label. The strategy of deciding which word path to extend includes the forming of a likelihood envelope against which the word paths are compared to determine if a word path is sufficiently likely to be extended. From among the word paths that are found to be extendible, the word path of highest likelihood  in the earliest  stack  --i.e.  the shortest most likely word path-- is selected for exten-sion. After a word path is extended, it is deleted from its stack and the word paths extended therefrom are en-tered into appropriate stacks.

Abstract: ABSTRACT OF THE DISCLOSURE        The daylight enters the room through at least one inner light port which is limited at the top by a flat upper reflector and at the bottom by a parabolic lower reflector.  A diagonal beam having a diagonal angle passes through the upper edge of the inlet window and through the lower edge of the inner window.  All of the light entering through the light port is emitted into the room above the diagonal beam.  To accomplish this, the lower reflector represents, in cross-section, part of a parabola whose main axis passes through the upper edge of the inlet window, and which forms with the vertical an upwardly directed main axis angle.  Also, the angle of inclination measured from the main axis of the upper reflectir is equal to half the diagonal angle measured in relation to the main axis.  By superimposing an outer light port, a given window surface can be better exploited and can be protected from interference light entering from below.

Abstract: ABSTRACT OF THE DISCLOSURE            The present invention provides a method and apparatus for attaching a ring-like part to the outer periphery of a columnar material.  The columnar material is positioned and supported with its axis oriented horizontally.          A guide member is supported from the side to position it adjacent to the columnar material on the same axis as the columnar material.  The guide member has an outer inclined surface enlarged towards the columnar material.  The guide member is then supported in the axial direction and at the same time, has the side support thereof released.  The ring-like part is then pushed while guiding it on the outer inclined surface of the guide member to fit it over a portion of the columnar material.  The pushing of the ring-like part is released and then the guide member is again supported from the sides, while at the same time, the support thereof from the axial direction is released.  Using the disclosed method and apparatus, it is possible to attach the ring-like part to the columnar material without previously passing the ring-like part over the guide member.

Abstract: ABSTRACT A television receiver responsive to a broadcast television signal in a normal operating mode includes a television signal channel with high frequency peaking circuits, followed by a display driver to which an auxiliary video signal may be applied.  A low pass filter is connected between the output of the television signal channel and the display driver, which exhibits a wide bandwidth when the receiver is intended to display auxiliary video information.  The bandwidth of the low pass filter is inversely related to the bandwidth of the driver such that the low pass filter exhibits a narrow bandwidth relative to the bandwidth of a wideband display driver.
