Abstract: 725,726. Arc lamps. GRETENER, E. April 2, 1953 [April 7, 1952], No. 9267/53. Class 39 (1). High intensity arc lamp for continuous operation having positive or negative carbon electrodes with mating ends one of which is inserted into the other and which are covered with a binding paste which can be fused and rendered electrically conductive by heating, has a heater disposed at the rear of and close to the electrode holder so that fusing of the mated electrodes is effected before they enter the arc. As shown in Fig. 2 the electrodes are composed of a pure carbon shell 20 and a core 21 having an admixture of metal salts. Each electrode is provided with a plug 22 and a socket 23 containing binding paste 24, covered by a cap 26 which is pierced when the plug 22 of another electrode is inserted in the socket 23. Lateral holes 25 may be provided in the socket 23 through which excess of paste and its evaporation and combustion products generated during fusing can escape. As shown in Fig. 1 positive carbons 13 are contained in a magazine 12 and are pressed upwards by a spring 14, the uppermost carbon being moved into the electrically heated oven 8 by spring rollers 15 driven through a slip clutch and the following electrode being joined to it. The oven may only be heated as a joint between electrodes passes through. The electrode magaine may be cooled. The oven 8 is preferably located within the shadow cone cast by the electrode holder 6. A scraper 16 removes remnants of the paste forced out of the socket 23 during fusing. Rollers 7 feed the joined electrodes to the holder 6 having current contacts. Similar devices are provided for advancing the negative carbon 3. The positive holder 6 acts as an air nozzle, having a ring shaped opening 9 from which an arc stream 10 issues, an exhaust funnel 11 being provided on the negative side which removes the arc stream and the flame gases. The crater 4 is located at the focal point of a concave mirror 5. The invention can be applied to the negative electrode but in general this will not be necessary owing to its lower consumption, particularly if the rod-shaped electrode is replaced by a disc-shaped electrode, the arc terminating on the disc edge.

Title: Improvements in or relating to colour television receiving apparatus
Inventor: JACKSON RICHARD NORMAN
IPC: H04N11/14
Filed: 1961-03-17
Abstract: 937,152. Colour television. MULLARD Ltd. Feb. 1, 1962 [March 17, 1961], No. 9841/61. Drawings to Specification. Class 40 (3). In a colour television reciver employing a single-gun cathode-ray tube adapted to display received signals of the N.T.S.C. type in a dotsequential manner, a circuit is arranged to modify the received signals, which are in terms of a first set of primary colours, into signals in terms of a second set of primary colours, one of which colour differs from the corresponding colour of the first set, which second set is appropriate to the cathode-ray tube employed. The invention is described as applied to a cathoderay tube in which the red and blue phosphors correspond in colour to the transmission primaries but the green phosphor differs being less saturated and has C.I.E. co-ordinates approximately equal to x=0.260 and y=0.570. The general procedure is: (1) to modify the N.T.S.C. chrominance signal into a dot-sequential colour signal (i.e. a signal of the form S=E<SP>1</SP> R  sin wt+ E G <SP>1</SP> sin (wt+120 degrees)+E<SP>1</SP> B  sin (wt+240 degrees)), but to increase the amplitude from 0.66 to 0.75, and (2) to modify the luminance signal Y to a monochrome signal of the form EW<SP>1</SP>=0.38 E R <SP>1</SP>+0.25 E G <SP>1</SP>+0.38 E B <SP>1</SP> - 0.06S, where the first three terms of the expression are obtained by combining with the original luminance signal a signal 0.08 E R <SP>1</SP>-0.34 E G <SP>1</SP>+ 0.27 E B <SP>1</SP> which is derived by synchronously detecting the original chrominance signal at angle of 22.5 degrees with respect to colour reference and a gain of about 0.75, preferably 0.74, and the last term is obtained by envelope detection of the modified colour signals. A system for carrying out the invention is described in block diagram form with reference to Figs. 5-7 (not shown), and Proc. I.R.E., Vol. 42, January, 1954, pages 299-308, is referred to in connection with the detailed operation of the type of circuit used. According to modifications the term - 0.063 in the monochrome signal may be derived from the original chrominance signal or may be dispensed with with a loss of colour fidelity. The Provisional Specification describes systems in which simultaneous colour component signals are matrixed to provide further colour signal appropriate to the primaries employed in the cathode-ray tube. Specifications 865,663, 865,666 and 890,395 are referred to.

Filed: 1986-11-24
Abstract: The present invention comprises novel DNA com­pounds that encode isopenicillin N synthetase. The invention also comprises methods, transformants, and polypeptides related to the novel DNA compounds. The novel isopenicillin N synthetase-encoding DNA, together with its associated transcription and translation activating sequence, was isolated from Penicilliumchrysogenum. The isopenicillin N synthetase-encoding DNA can be used to construct novel E. coli expression vectors that drive expression of isopenicillin N syn­thetase in E. coli. The intact P. chrysogenum iso­penicillin N synthetase-encoding DNA and associated transcription and translation activating sequence can also be used to construct expression vectors that drive expression of the isopenicillin N synthetase in P. chrysogenum and Cephalosporiumacremonium. The transcription and translation activating sequence can be fused to a hygromycin phosphotransferase-encoding DNA segment and placed onto expression vectors that function in P. chrysogenum and C. acremonium. The transcription termination and mRNA polyadenylation signals of the P. chrysogenum isopenicillin N synthetase can be used to increase ultimate expression of a product encoded on a recombinant DNA vector.
