Abstract: The invention relates to an antenna attached to a vehicle roof glass, i.e. a glass plate fitted in an opening of the roof of a vehicle body such as an automobile body, for receiving FM radio and TV broadcast waves in both the VHF band and the UHF band. Essentially the antenna is comprised of a main element which is a conductive strip attached to the roof glass and bent so as to make a closed plane figure, a feed point attached to the roof glass and a connection line which connects the main element to the feed point and extends parallel or nearly parallel to the longitudinal center axis of the vehicle body. The total length of the main element is from 200 to 1500 mm. For example, the main element makes a rectangle in a central region of the roof glass with two opposite sides of the rectangle parallel to the aforementioned center axis. Optionally the antenna may include an auxiliary element which is a conductive strip attached to the roof glass and connected to the feed point.

Abstract: A method of addressing a display device comprising a matrix of separately operable pixels is provided. The method comprises the step of applying across a given pixel a voltage waveform comprising a latching pulse and an auxiliary pulse of amplitude smaller than the latching pulse. The amplitude of the auxiliary pulse is modulated to determine the latching effect of the latching pulse.

Abstract: The invention relates to a method of toughening a glass sheet by heating it to a temperature above the strain point and quenching the heat glass sheet while it is advancing horizontally by blowing cooling gas jets onto each face of the glass sheet from an array of nozzles. In advance of such quenching, the heated glass is preliminarily cooled to some extent so as to cool the glass sheet at a relatively high rate in substantially parallel stripe-like regions, which make an angle greater than 45.degree. and not greater than 135.degree. with the direction of advance of the glass sheet, than in other regions. As a result, relatively high toughening occurs in the stripe-like regions. Preferably the preliminary cooling is made only in a central area of the glass sheet. The preliminary cooling has the effect of compensating a toughening pattern attributed to the unidirectional movement of the glass sheet under quenching, so that the toughened glass sheet is satisfactory in the manner of fragmentation.

Abstract: Uniquely contoured interior surfaces have been found to stabilize the flow patterns through centrifugal pumps of the volute type, especially pumps having wide impellers and wide volutes for pumping slurries. The contoured interior surfaces may be provided in the pump casing, but are preferably defined by a volute liner. The interior surfaces comprise a volute region and a discharge nozzle region which both are at least in part contoured interior surfaces and which cooperate to provide a flowingly contoured interior surface of changing axial cross-section.

Abstract: The commutator comprises a commutator base and a plurality of commutator segments. The base is in two parts. One part is a pre-formed base part and the other part is moulded to the base part after the segments have been located on the base part to firmly secure the segments thereto. The commutator is of the barrel-type and the base part is tubular and has castellated ends. The segments have apertured lugs which engage with the castellated ends of the base part and extend inside opposite ends of the base part to locate the segments relative to the base part. The other part of the base forms a sleeve inside the pre-formed base part and firmly secures the lugs and hence the segments to the pre-formed base part.

Abstract: A cutter is described for cutting through an article, such as an envelope, at a given distance from its edge, approximately straight and parallel to the edge. An edge portion of the article to be cut, such as an envelope, is positioned on a floor, and then it is slid with its edge in contact with a sliding side surface perpendicular to the floor. The thing to be cut is pressed against the sliding surface with a press means when cut and slashed with a blade edge at a given distance from the envelope edge approximately straight and parallel to the edge.

Abstract: In a first stage of a process for the preparation of 6-piperidino-2,4-diaminopyrimidine-3-oxide at least one of the two amino groups of a compound having formula (1): ##STR1## where X represents a halogen atom or OH group, is protected by an addition reaction with an isocyanate having formula:R--N=C=OIn this formula R represents an alkyl group, or one of the amino groups. The resulting urea derivative is then oxidized to produce the corresponding N-oxide which is then reacted with piperidine. The protective group(s) are then eliminated by reaction with an organic or inorganic base.

Abstract: The ejecting arrangement has two ejecting wheels which are designed in saw-toothed form on their circumference. The ejecting wheels can be swiveled out of a position in which they are turned by half a tooth pitch with respect to each other into a position in which the stops of the two ejecting wheels are mutually aligned. If the ejecting wheels are offset with respect to each other by half a tooth pitch, each printing product inserted into a pocket of the paddle wheel runs onto a stop and is ejected by the latter from the pocket due to the different speeds of the paddle wheel and of the ejecting wheels and is deposited in imbricated formation onto the delivery conveyor. If, on the other hand, the stops of the two ejecting wheels are mutually aligned, the printing products of two successively occupied pockets in each case make contact with a stop, as a result of which the two printing products are ejected from the pockets mutually aligned with their fold.
