Abstract: A METHOD FOR REFRESHING MULTICOLUMN TABLES  USING MINIMAL INFORMATION                      Abstract of the Invention A method for refreshing a relational data base snapshot manifest in the form of remote read-only copies of selected portions of a base table.  The method takes advantage of the fact that each tuple of the base table has a unique identifier TID associated therewith from the time the record is inserted until it is deleted.  The TID references the physical location of the tuple within its relation.  Two system-maintained fields are added to the base table.  These are PREVTID and update ID.  One system-maintained column is required in the snapshot table, i.e. BASE TID.  Lastly, a column in the catalog of the snapshot is also maintained, i.e. SNAPHIGH.  When the refresh of the snapshot table is required, a single scan of the base relation, in ascending TID sequence, is performed on the base table.  The scan produces a series of messages which contain the incremental changes required to update the snapshot table to the current state of the base relation.  Upon receipt of the messages at the snapshot table site, a single skip sequential pass across the snapshot in BASE TID sequence is performed to apply the incremental changes.  This refreshes the snapshot table to the required state.

A chopping wheel provided with a suppporting plate is rotatable around an axis of rotation and cutting elements fixed to said supporting plate is located in the casing.  Between the casing and a discharge duct joined to the casing, brush cutters are arranged in a discharge passage for material discharged by the chopping wheel, such that in operation material discharged by the chopping wheel moves through the brush cutters to the discharge duct.  Blades that are prov-ided at the side of the supporting plate of the chopping wheel are turned away from the cutting elements and/or to the brush cutters, and the width of the brush cutters, measured in the direction of the axes of rotation of the brush cutters, is smaller than the width of the discharge passage measured in the same direction.  With this arrangement in operation air displaced by the blades flows beside the brush cutters through the discharge passage to the discharge duct.

Abstract: ABSTRACT OF THE DISCLOSURE              A telephone terminal or a combined telephone-dictation terminal is disclosed.  Such telephone apparatus includes a handset having a microphone and a speaker together with a speakerphone having a microphone and a speaker.  Such telephone apparatus also includes a hook switch, which detects on-hook and off-hook conditions of the handset, a speakerphone switch, and a control mechanism, which is responsive to the hook switch and the speakerphone switch.  The control mechanism may successively enable and disable at least one of the speakerphone microphone and the speakerphone speaker in response to successive operations of the speakerphone switch during the on-hook condition.          Preferably, such a control mechanism (a) enables the speakerphone microphone and the speakerphone speaker when the speakerphone switch is operated a first time during the on-hook condition; (b) disables the speakerphone microphone when the speakerphone switch is operated a second time during the on-hook condition; and (c) reenables the speakerphone microphone when the speakerphone switch is operated a third time during the on-hook condition.  The control mechanism may enable the headset microphone and the headset speaker in response to a change from the on-hook condition to the off-hook condition and then enable the speakerphone speaker when the speakerphone switch is operated a first time during the on-hook condition.  Such a control mechanism desirably disables the headset microphone when the speakerphone switch is operated a second time during the off-hook condition and reenables the headset microphone when the speakerphone switch is operated a third time during the off-hook condition.

The circuit comprises a differen-tial transconductance amplifier having two output terminals that are connected respectively to the first and second output terminals of the circuit.  The amplifier has the property that it responds to an input voltage Ee between its input terminals by pro-viding a current equal to Eegm1/(1+?s) (where gm1 is the transconductance of the amplifier, ? is the response time constant of the amplifier and s is the Laplace transform operator) at its output terminals.  Two equal-valued capacitors are connected respectively between the first input terminal of the circuit and the first output terminal of the circuit and between the second input terminal of the circuit and the second output terminal of the circuit, the capacitance Cc of each capacitor being such that RsCc is much greater than ?.  The circuit also comprises two equal-valued resistors connected in series between the first input terminal of the circuit and the second output terminal of the circuit and having their connection point connected to one of the input terminals of the amplifier, and two more equal-valued resistors con nected in series between the first output terminal of the circuit and the second input terminal of the cir-cuit and having their connection point connected to the other of the two input terminals of the amplifier.  The value of gm1 is selected to be equal to (1/2Rs + 1/R).

Abstract: The present invention relates to a method for purifying silica waste obtained in the manufacture of aluminium fluoride from hexafluosilicic acid and aluminium hydroxide, whereby the silica, is subjected to an acidic leaching at a pH below 3 to leach out part of the fluorine and substantially all the aluminium present in said waste, and is thereafter subjected to an alkaline leaching at pH 8.5-11.5 to leach out remaining fluorine present in said waste. The teachings are preferably carried out at elevated temperatures, normally 60-90°C, and for a time sufficient to considerably reduce the contents of aluminium and fluorine, normally 1-3 hrs.The silica obtained is highly reactive and can be used as such or transformed into sodium slicate by a reaction with sodium hydroxide. The contents of fluorine and aluminium can be transferred to a process for the production of cryolite or similar compounds.

Abstract: The marine screw propeller comprises blades 2, each having parallel edges and a constant cross section, and a ring 3 in the form of an annular casing, which is fixed to the outer ends of the blades. The casing is preferably of truncated cone shape on the inner side 4, and curved on the outer side, producing a hydrofoil profile, except for the leading edge, which has a concave inclined cut- off on one or both internal and external surfaces. The screw propeller is less prone to fouling and structural damage, since the blades are protected by the casing and are therefore less prone to catch in lines of various types. The marine screw propeller produces a neutral torque, so that turbulence around the screw is avoided. Furthermore, the casing has an oscillation-damping effect, so that the screw propeller can be fitted closer to the ship hull than known screw propellers. <IMAGE>

Abstract: A filter, for protection against the sun, of improved contrast sensitivity has a spectral transmission (T lambda ) which for wavelengths ( lambda ) of the incident radiation in the range  lambda < 350 nm </=1% and in the range 350< lambda <400 nm is less than 20%, and which in the range 400< lambda <500 nm reaches a value of 5-30% and thereafter, proceeding from the value for T500, increases linearly with the wavelength to its maximum value. This progression is achieved by coating or colouring the filter material. In this case, it is advantageous to provide a component of the coating or colouring so that the spectral transmission (T lambda ) outside the visible spectral range, i.e. for values  lambda >780 nm, quickly reaches a value <1% again. <IMAGE>
