Abstract: PURPOSE:To manufacture a winged needle efficiently and cheaply by melting synthetic resin in a die utilizing high frequency heating to form a wing part and fixing a needle to a tubular body. CONSTITUTION:Sheets 3, 3' made of thermoformable synthetic resin of wing forming material are set up on both sides of a tubular body 2 and pressure bonded with dies 4, 4' between. Base of a needle 1 is inserted beforehand in the tubular body 2. High frequency current is applied using the die 4 as an electrode, and the sheets 3, 3' are either softened or molten to form a wing part, and at the same time, unified with the tubular body 2. After forming the wing part, the tubular body 2 is heated and softened by high frequency current using the needle 1 as an electrode, and the needle 1 and the tubular body 2 are fixed to form a winged needle. This method can be applied to manufacture any of winged needles for medical use such as a winged intravenous injection needle etc.

Abstract: A position measuring instrument comprising a graduation unit and a scanning unit. The graduation unit comprises a centering flange, a graduation carrier and a measuring graduation located on the graduation carrier. The scanning unit comprises a scanning component which comprises a scanning graduation and a stop. During assembly, the scanning unit is positioned radially with respect to the graduation carrier by positioning the stop against the centering flange. The scanning component may then be moved along a guide towards the measuring graduation. As the scanning component is moved towards the measuring graduation the stop no longer contacts the centering flange. A spacing foil removably sandwiched between the measuring graduation and the scanning graduation is used to position the scanning graduation at a predetermined distance from the measuring graduation. A locking means is then used to prevent further movement of the scanning component along the guide.

Abstract: A method of operating a display comprising a lattice of pixel elements (20), includes the step of time-multiplex addressing collections of pixel elements. This addressing step includes using a first shift register means (4, 26, 28) to designate operation of a second shift register means (6, 30, 32) to select a function to be performed. If the second shift register means (6, 30) is in bypass mode, then the first shift register means (4, 26) is effective as a mask to specify which of the stages in the second register means should be bypassed, and allows non-sequential group addressing of the pixel elements. Such an arrangement (2, 22) of first and second shift register means is suitable for use in controlling the addressing of collections or rows of pixel elements; the function to be selected by the second shift register means is the strobing of the collections or rows.

Abstract: For the manufacture of lactulose, an alkaline aqueous solution of lactose and borax is prepared and heated at a temperature above 80 DEG C. The lactulose is separated from the resulting conversion products. Apart from the borox, no alkalising material is added to the solution. The conversion is carried out at pH 8.3. In order to maintain the sodium ions in the production cycle, the borox may be manufactured in an aqueous solution of boric acid and already simultaneously with the lactose, while the sodium ions are transferred from the solution of the conversion products in the solution of the boric acid by electrodialysis. Alternatively the sodium ions may also be removed from the solution of the conversion products as readily as possible by means of a weakly acid ion exchanger and only thereafter by means of a more strongly acid ion exchanger. The weakly acid ion exchanger is regenerated with boric acid so that borax is formed again.
