Abstract: Apparatus for encoding/decoding a HDTV signal for e.g., terrestrial transmission includes a compression circuit responsive to high definition video source signals for providing ierarchically layered codewords CW representing compressed video data and associated codewords T, defining the types of data represented by the codewords CW. A priority selection circuit, responsive to the codewords CW and T, parses the codewords CW into high and low priority codeword sequences wherein the high and low priority codeword sequences correspond to compressed video data of relatively greater and lesser importance to image reproduction respectively. A transport processor, responsive to the high and low priority codeword sequences, forms high and low priority transport blocks of high and low priority codewords respectively. Each transport block includes a header, codewords CW and error detection check bits. The respective transport blocks are applied to an forward error check circuit for applying additional error check data. Thereafter the high and low priority data are applied to a modem wherein they quadrature amplitude modulate respective carriers for transmission.

Abstract: The machine is particularly for paper strip (PB), having two rollers (TW1,TW2) supporting the coil to be formed (R). The casings (M1,M2) of the rollers distort, preferably to different degrees. During the coiling operation, the strip passes through the gap (G) between the rollers and part-way round one of them. The chamber (DR) between the rollers and the partly-farmed coil is sealed at the ends and underside and supplied with compressed air to relieve the weight of the coil. The seal below the gap has a sidewall (11) extending for the maximum overall width of the coil to be formed, and hinging on an axis (11A) parallel to those of the rollers. It swings between a position forming a seal against the roller round which the strip passes, while leaving a gap (GP) through which the strip passes during coiling, and one clear of the roller to allow the strip to be threaded into place. The gap (GP) an be extended by guide faces clear of the roller in the radial direction and towards the incoming strip.

Title: Improvements in and relating to three-phase feeder protective systems
IPC: H02H3/34
Filed: 1946-01-11
Abstract: 630,557. Protective cut out systems. GENERAL ELECTRIC CO., Ltd., and FRIEDLANDER, E. Jan. 11, 1946, No. 1030. [Class 38(v)] A protective system for a three-phase feeder gives protection against interphase, earth and over-current faults by using a filter circuit which produces a single-phase current, the magnitude and phase of which is dependent upon the magnitude of the positive sequence components of the feeder currents, with the addition of a larger zero sequence component to increase the sensitivity of the circuit to earth faults. One filter circuit may be used to operate a relay to give local protection. In a differential protective arrangement a suitable relay may be connected between two spaced filter circuits by means of two pilot wires or by radio link. In Fig. 3, the secondary windings TR, TY, TB, of three current transformers are connected at one end to form a neutral and windings TR, TB, are connected at their other ends to a reactor X, whilst. the other end of winding TY is connected to a resistor R1, which in turn is connected to a central tapping point on the reactor X. A relay Z connected between the ends of the windings TR, TY, is energized by a current dependent on the positive sequence components derived from the circuit so far described. The provision of a further winding X<SP>1</SP> on the core of the reactor and connected between the reactor and the neutral point of the current transformers introduces the larger zero sequence component into the relay coil Z. In Fig. 2 (not shown), a further current transformer used in the place of the winding X<SP>1</SP> has its primary winding connected between the neutral point and the centre tapping of the reactor, its secondary winding being connected across the relay Z. In a further modification, Fig. 1 (not shown), a resistance, replacing the winding X<SP>1</SP>, is connected between the neutral point and the end of the resistance R1, the relay coil being connected between the neutral and winding TR.

Abstract: 640,453. Aerials. COSSOR, Ltd., A. C., and BELL, D. A. Jan. 14, 1947, No. 1235. [Classes 40 (v) and 40 (vii)] An aerial system comprises a dipole supported upon a parallel-element stab whose length is less than a quarter of the operating wavelength, and a condenser connected between the stub elements at their junction with the arms of the dipole for tuning the electrical length of the stub to a quarter-wavelength. In Fig. 1 the aerial system comprises a primary element 11 and reflector 12 spaced a quarterwavelength apart and supported upon a mast 13 positioned centrally between them. The dipole 11 is supported by a stub 14, an eighthwavelength long, which is formed integrally with the limbs of the dipole and short-circuited by a member 15. A condenser 16, housed in a water-tight casing 17 which serves also as-a mechanical brace, is connected between the inner ends of the dipole to cancel out the nductive reactance of the stub. The dipole is fed by a cable 18 which is brought through one of the elements of the stub, these being tubular, and is connected to the inner ends of the dipole as shown. Fig. 2 shows an arrangement comprising a short-circuited co-axial stub adapted for mounting on a wall. The characteristic impedance of the stub in this construction is less than in the former, thus resulting in a broadening of the frequency response of the aerial.

Title: Improvements in delivery apparatus for cylinder printing presses

Filed: 1929-01-14
Abstract: 327,975. B³ttner, A., and Schnellpressenfabrik Akt.-Ges. Heidelberg. Jan. 14, 1929. Cylinder machines; set-off, preventing. - In a printing- machine in which the cylinder a and bed dare both reciprocated, the sheet-delivery carriage h reciprocates with the cylinder a and only feeds the sheet forward during the backward movement of the cylinder. The delivery apparatus comprises two conveyer bands h<1>, h<2> passing, at their adjacent ends, over a common pulley g' driven from the inking-roller mechanism through an intermediate gearwheel m. A free-wheel device on the shaft n of the pulley g', however, allows movement of the bands relatively to the carriage h only on the movement of the cylinder a towards the feed-table c so that the bands act as a drop-sheet delivery for depositing the sheets on the table l. The combined length of the bands h<1>, h<2> is such that the carriage h makes at least three reciprocations before the sheet is deposited, so that the printing has time to dry. Each part h<1>, h<2> may be pivoted upwardly about the shaft n so as to permit of easy access to the inking apparatus and the flat bed, and transparent plates p between the runs of the .bands protect the apparatus from dust. When the leading edge of the sheet reaches the highest point of the cylinder a after being printed, the cylinder grippers b are opened and a roller e engages the sheet so as to forward it towards the band h<1> until its leading edge is above the pulley g of the band h<1>, the cylinder a then being at the end of its travel. The roller e is then lifted and a roller i grips the sheet against the pulley g and it is forwarded on to the band h<1>. Fingers f strip the sheet from the cylinder. Longitudinal cutters may be provided on the pulley g.

Abstract: 885,374. Reservoir pens. CONWAY STEWART & CO. Ltd. April 1, 1959 [Jan. 15, 1958], No. 1427/58. Class 146(3) In a fountain pen wherein the nib is held between an inner feed bar and an outer sleevelike member surrounding the inner feed bar, the air which flows back to the ink reservoir to replace the used ink passes in series first along a bottom forward longitudinal air intake groove in the periphery of the feed bar, then along a transverse connecting air passage in the feed bar, and then along a top rear longitudinal air groove in the periphery of the feed bar, the top rear longitudinal air groove being angularly displaced about the periphery of the feed bar with respect to the bottom forward longitudinal air groove. As shown the feed bar 1 is formed with a deep, narrow ink groove 11 which intersects a plurality of circumferential ink overflow chambers 10 cut in the feed bar and also a circumferential groove 8 and which terminates at its forward end adjacent to the underside of the nib 3. The nib 3 is arcuate in cross-section and is wedged between the feed bar 1 and nib-section 2 in an arcuate recess 9 in the latter. At the rear end of the nib inturned lugs 7 engage in the groove 8 in the feed bar to prevent relative longitudinal movement between the nib and feed bar. An air passage 12 overlies the ink groove 11 and is wider and shallower than the latter. The passage 12 extends from the rear end of the feed bar and opens into the rearmost overflow chamber 10a. An air intake groove 13 extends from the front end of the feed bar, intersects the chambers 10 and opens into the chamber 10a. Air is fed to the reservoir 4 via the groove 13, chamber 10a and passage 12. When the chambers 10, 10a are filled with surplus ink the groove 13 is blocked and air cannot get to the reservoir which prevents escape of more ink therefrom until the overflow chambers have been emptied either by writing or draining back into the reservoir. In a modification the groove 13 and passage 12 are connected by a hole passing diametrically through the feed bar. Specification 885,375 is referred to.
