Title: Improvements relating to colour television receivers
IPC: H04N9/465
Filed: 1969-12-02
Abstract: 1293958 Colour television TELEFUNKEN PATENTVERWERTUNGS GmbH 2 Dec 1969 [2 Dec 1968 21 Jan 1969] 58752/69 Heading H4F The switching phase of the line switch 12 in a PAL colour television receiver is controlled by a circuit including a one line period delay line 2, the swinging burst at the input of the delay line being separated by a gate 6 and passed to one input of a phase comparison circuit 8, while the colour burst at the output of the delay line is fed via a phase change-over switch 9 to the second input of circuit 8. The output of circuit 8 is fed through a filter network 13 and a blocking stage 14 to the control input of a generator 11 to which is also applied the line flyback pulses 7, and the half line frequency switching waveform 10 of generator 11 controls the switch 9 and the PAL switch 12. In operation with correct switching phase of generator 11 and switch 12 the phase switch 9 is such that it converts burst sequence b into sequence c which when compared with sequence a produces only positive pulses d and thus a positive control signal at the output of filter network 13. Blocking stage 14 is dimensioned so that this positive control signal has no influence on generator 11. With incorrect switching phase sequence e is produced from sequence b by switch 9, and on comparing sequences a and e negative pulses f are formed which produce a negative control signal at the output of filter network 13. Blocking stage 14 responds to the negative control signal and stops generator 11. Phase switch 9 then remains in one of its positions. If it remains at + 90 degrees (or - 90 degrees) sequence g (or i) is formed and compared with sequence a to produce voltage h (or k) resulting in a zero value control signal. The blocking stage 14 does not respond to a zero control signal so that the generator starts to oscillator. This continues until generator 11 oscillates with the correct switching phase. In a PAL receiver with a transit time signal splitting circuit, sequence b may be taken from the output of the addition or subtraction stage, delay line 2 being constituted by the delay line in this splitting circuit. Phase switch 9 may be connected in series with gate 6. Switch 9 may be used in a PAL/SECAM -(Trade Mark) multiple standard receiver, in which for SECAM operation switch 9 effects the phase shift in a control circuit for the line switch. The control signal at the output of filter network 13 may also be used as a switching voltage for a colour killer since zero control signal is formed when sequence a is absent. Switch 9 may be arranged to be so controlled by waveform 10 that it shifts the phase of the burts sequence b by 90 degrees in alternate lines and suppresses completely the bursts in the intervening lines.

Filed: 1972-12-22
Abstract: 1451759 Cleaning conveyer belts C W WARD 30 Nov 1973 [22 Dec 1972] 59465/72 Heading B8A A pair of belt-scraping blades 22 are carried by respective arms 18 in advance of a second pair of blades 22 carried by a pair of arms 20. Each pair of blades is secured by taper plug and socket fixings 26, 28, connected by a bolt 30 to place the blades at a desired inclination to the belt. In a modification (Figs. 4 and 5, not shown), the blades are rotatably mounted in blocks (68) which are themselves rotatably mounted about a shaft (70) which is bolted to the outer end of the respective arm 18 or 20. The latter comprise leaf springs, and at their ends opposite to the scraper blades 22, they are each formed with a hexagon-shaped bore to fit a hexagon cross-section support rod 38 or 40. The rods 38, 40, are set to a desired position by means of an arm 64 (which is removable to enable it to be used for setting either rod 38 or 40). By rotating the arm 64, an apertured sector plate 48 rigid with the rod 38 (or 40), may be turned until the arms 18, 20, are in their correct positions for holding the blades 22 against the belt with a predetermined pressure. The plate 48 is then secured relative to an apertured plate A rigid with the conveyer frame, by means of a pin 50. By providing two apertures suitably spaced on the plate 48, a finer degree of adjustment of the arms is possible, than that provided just by the spacing of the apertures 54 of the plate A. In a modification (Fig. 6, not shown), the rods 38, 40, may be connected by a section (80) of hexagonal cross-section tube. In an alternative arrangement (Complete Specification drawing), each blade is mounted, as before, on a pair of arms 32, 34, which are rotatably mounted on the hexagonal crosssection shaft 38. An arm 88 rotationally rigid with the shaft 38, carries screws 86 by means of which the arms 32, 34, may be adjusted rotationally relative to the shaft 38. The blades 22 may alternatively be of triangular crosssection, as in Specification 1,331,222.

To clean combine harvested grain, it is fed from a hopper 2 on to an endless band sieve 3 oscillated by a rotating shaker 5. Large impurities fall into a chamber 12 at the end of the sieve belt and those particles which adhere to the belt are removed by a brush 23. After falling through the sieve, the grain, still containing fine and light impurities, is subjected to a transverse air current 17 produced by a suction fan 16. The fine and light impurites are entrained in the air current and are removed from the air by deposition on an air-permeable rotating filter disc 9. The filter disc has a rim 25, a hub 24 and three sections separated by radial vanes 21 (see Fig. 2). A filter gauze 18 covers all three sections. In operation, only part of the filter disc is within the air-stream containing the fine and light impurities; the other part depends into a chamber 11 where the impurities fall or are brushed off the filter gauze. The vanes 18 act as seals between the chamber 11 and air-stream passage 19. Large and fine impurities are removed through airlocks 13, 14.

Title: Reading and writing information on a storage medium
IPC: G11B20/14
Filed: 1969-12-23
Abstract: 1285729 Data storage SINGER NV 23 Dec 1969 [27 Dec 1968] 62631/69 Heading G4C The frequency of clock pulses for interpreting digital data on a movable, erasable, storage medium is synchronized with the speed of the storage medium during read or write operations by reading markers in the data track. Non- return to zero information pulses are stored on a disc, a binary 0 having a pulse width twice that of a binary 1. Each character has the same length however by adding blank spaces to the 0's and 1's, and the first pulse of each character is read as a clock pulse. The read head 1 selects the first pulses and feeds them to a logic circuit 2 where they are lengthened (Fig. 4, waveform B, not shown). A clock pulse generator 3 feeds its pulses through a frequency divider 4 to a comparator 5 having the pulses of waveform B as its other input. Any difference between the frequency of the first pulses from head 1 and the clock generator 3 frequency causes negative feedback which causes a corresponding adjustment of the frequency of generator 3. This is said to be of use when writing fresh data on parts of an already written disc. A counter may be used to distinguish binary 0 and 1.
