Title: Circuit arrangements for pal colour television receivers
IPC: H04N9/465
Filed: 1972-08-19
Abstract: 1437949 Colour television EMI Ltd 30 July 1973 [19 Aug 1972] 38785/72 Heading H4F In a PAL demodulator, alternate bursts SA (correct) or SB (incorrect) at input 1 are gated at 4 by the output of a bi-stable 6 triggered by line sync pulses 5, the gated bursts being fed via a - 45 degree phase shifter 4a, to a phase controlled oscillator 7, the output of which is fed, via + and- 90 degree phase shifters 7a, 7b to the PAL switch 8. The switch is controlled by the bi-stable 6, which control may be incorrect giving antiphase demodulation of the (R-Y) chrominance component. To stop this incorrect control, use is made of the fact that the last burst before a blanking interval is a SA and the first burst of the next field (nine line periods later) is also a SA. There should thus be four 1 states of bi-stable 6 during which the consequent enabling of gate 4 produces no burst at input of sense detector 10. Such lack of burst produces a 1 from the detector, which, together with the output of the bi-stable 6, gives corresponding 1's from AND gate 11. These last 1's advance a counter 12 to count 4 before it is reset to 0 by the first gated SA burst. If the operation is incorrect, AND gate 11 produces five 1's which advance the counter to count 5 and cause a "hold" signal to go to bi-stable 6 to hold its state and restore correct operation.

Title: Integrated storage system
IPC: G11C11/417
Filed: 1974-09-06
Abstract: 1465120 Storage devices PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 6 Sept 1974 [11 Sept 1973] 39062/74 Heading G4C A storage device including a plurality of multi-element integrated circuit stores CEL0- CEL11 (Fig. 2) comprises for each driver element DR13-DR15 a number of branch lines connected in groups at one end to a common junction and at the other end to one of the stores, each branch line incorporating a series resistance. For example the driver DR13 is connected via resistors R31, R32, R33, R34 (arranged in star formation) to groups of cells CEL0- CEL2; CEL3-CEL5; CEL6-CEL8 and CEL9-CEL11 respectively. This arrangement reduces the capacitive cross-talk between bit lines since pairs of resistors R31, R33; R32, R34 act as voltage dividers so reducing the interference voltage received at decoders DEC0- DEC11 associated with each cell. As described each driver comprises two pairs of transistors, one pair (T1, T3, Fig. 3, not shown), normally conductive and a second pair (T2, T4) which are normally cut off to keep a junction (KN) at a high potential, a selection signal at an input terminal (K8), switching over the conductive states of the transistors. Interference exists between a clock pulse line (L5) and selection signal lines (L1-L4) but resistors (R6-R9) which correspond to resistors R31- R34 in Fig. 2 and the internal resistances of the drive unit constitute a voltage divider so that the influence of the interference is small.

Title: Screw pump
IPC: B23C3/32
Filed: 1963-10-04
Abstract: 972,420. Rotary screw pumps. G. R. LINDBERG. Oct. 4, 1963 [April 23, 1963], No. 39130/63. Heading F1F. A rotary screw pump of the Moineau type comprising a casing 26, Fig. 1, having an inlet 30 and outlet 28, houses a stator 12 consisting of a sleeve 16 with an insert 14 of rubber or similar material having a two-start helical thread co-operable with a one-start helical thread of half the pitch formed on a rotor 10. The rotor is connected to a drive shaft 18 by means of an axle 20 which passes through the hollow rotor and universal joints 22, 24 for eccentric and rotational movement within the stator. To reduce manufacturing costs whilst at the same time maintaining contact between the rotor and stator the internal enveloping surface of the stator is generated by an ellipse having a major axis 2a, Fig. 4, and a minor axis 2b which travels along an axis C STAT  perpendicular to the plane of the ellipse while simultaneously continuously turning about the axis to produce a helix of pitch S. A complementary rotor with a pitch S/2 is produced and disposed in the stator with its axis C ROF  at a distance e equal to a-b/2 from the axis C STAT . The stator is produced by first producing a core i, Fig. 6, whose outer surface is generated by a single helical line of a diameter a+b, which turns whilst simultaneously executing an eccentric movement in a combined longitudinal and circular feed device by allowing the cutting tool to travel along the path r-r a great number of times. The Specification proves mathematically that this surface is identical to that generated by the ellipse. A rubber moulding made round the core is then removed by screwing when the rubber is cured to produce the stator. The rotor may be manufactured by taking a blank 34, Fig. 9, which is mounted in a longitudinal and circular feed device and is machined by a rotating shank end mill 36. The longitudinal feed being S/2 for each rotation of the blank. Alternatively the shank and mill may be replaced by a cutter (not shown).

Abstract: 1,271,739. Cathodically protecting offshore structures. SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ N.V. Aug. 7, 1969 [Aug.9, 1968], No.39634/69. Heading C7E. Metals in particular offshore structures such as oil-drilling rigs, are cathodically protected by coating the metal with an insulating material, which is water-insoluble and capable of adhering to dirty metal, positioning in saline water, and supplying electrons so as to maintain the metal surface at a potential less than or equal to -0À85 V w.r.t. a Cu/CuSO 4  half-cell. The normally rusty metal surface may be sprayed with an insulating coating of latex paint or solvent- or water-based bitumen, to give a 1-4 mil coating. This coating favours formation of glassy calcareous deposits on the metal, which deposits restrict oxygen access thereto, thus inhibiting corrosion and causing a lower cathodic current requirement.
