IPC: H04N5/50
Filed: 1960-11-25
Abstract: 958,039. Automatic frequency control systems; tuning indication. PHILIPS ELECTRICAL INDUSTRIES Ltd. Nov. 25, 1960 [Nov. 30, 1959], No. 40604/60. Headings H3A and H3Q. In a television receiver an off-tuned resonant circuit 16 is energized by vision I.F. from the output of a video detector circuit 12-14 and its output, across capacitor 19, differentially combined with part of the output, across potentiometer 14, of the video detector so that the combined output is zero when the vision I.F. carrier is nominally correct in value i.e. centred mid-way of the Nyquist skirt portion of the I.F. pass-band, but is positive or negative for frequency drifts about the correct value due to tuned circuit 16 having a steeper slope of output with frequency variation than that from potentiometer 14. The combined output is then fed through a cathode follower 31 to vary the impedance of a diode 33 connected in series with a capacitor 35 across a local oscillator tuned circuit to correct the I.F. To avoid output variation with mean brightness the cathode follower 31 may have its anode, otherwise at zero potential, energized by constant level flyback pulses occurring during sync intervals, smoothing circuit 38, 32 preventing action on the diode 33. Further, rectifier 18 may be replaced by a transistor amplifier/detector similarly pulse keyed. In a modification circuit 16 is series resonant connected across the output of detector 12. Alternatively the systems may be used for tuning indication.

Title: Forming coded holograms
IPC: G07F1/06
Filed: 1971-09-02
Abstract: 1328629 Holography OPTRONICS INTERNATIONAL 2 Sept 1971 [9 Sept 1970] 41051/71 Heading G2J A coded hologram, for use in an identity card, is made by introducing a beam scrambler 34 into either the reference beam 42 or the object modified beam 44. The beam scrambler may be transmissive or reflective and introduces random path differences in the appropriate beam e.g. by having random variations in refractive index. This may be caused by the scrambler including a planar surface having random surface deformations which may be moulded into the surface. Preferably a diffuser plate 60 is included the object beam 44 before the object 62. Where the scrambler 34 is located in the reference beam an asfocal lens system 50 focuses an image of the scrambler on the hologram plate 54. To reconstruct the image to give the desired identification the illuminating beam is the same as the reference beam 42 with the coded hologram being located at the focused image of the scrambler. Identification may be by photocells located in the object image plane. An 'incoherent light source may be used which is filtered to give a single wavelength and then concentrated by a pinhole before impinging on the beam splitter.

Title: Method of and machine for positioning railway sleepers
IPC: E01B29/10
Filed: 1961-11-24
Abstract: 935,677. Laying railway sleepers. FILS D'AUGUSTE SCHEUCHZER S.A. Nov. 24, 1961 [Nov. 28, 1960; Nov. 17, 1961], No. 42195/61. Class 104(2) For laying sleepers on a railway track a machine displaceable along the track carries a sleeper support member 20 which is slidable in a fore-andaft direction along a beam 1, the beam being mounted on a shaft 13 pivotable about a substantially vertical axis in bearings 11, 12 in a frame 10. To move a sleeper from one side of the track to its position of use, the support 20 is moved, by means of a shaft 21 and handle 22, rearwardly along the beam 17, the beam is then pivoted through 90 degrees towards the side where the sleeper is located and the support is moved back to the forward end of the beam, the shaft 21 being guided in these movements by a T- shaped slot 9, Fig. 2, in the upper plate 1, 8 of the machine. A sleeper is then laid on the support and the reverse movements of support and beam are carried out until the sleeper is in position under the rails 5, 6. During the rotary movement the sleeper has  been raised slightly due to the shaft 13 being mounted at a slight angle to the vertical. The sleeper is pressed against the underface of the rails, to be secured thereto by conventional means, by depressing a pedal 23 which through levers 24-27 causes a bearing surface 28 on the lever 26 to contact a ring 18 on the beam 17 to rock the beam about an axis 16. Fig. 6 shows a modified frame 10 and support 20 which enables a sleeper to be moved to a position along the longitudinal axis of the track during the lateral movement of the support. In a second embodiment, Fig. 7, the beam 17 is pivotable about a vertical axis relative to a cross-member 37 itself pivotable relative to the machine frame 33 about a horizontal axis. The beam is locked in the selected angular position relative to the frame by a lock 38 operated by rotation of a drum 47 to which it is connected. The sleeper support 20 is slidable along the beam 17 by means of a motor (not shown) driving an endless chain 42 fixed to the support. The plate 39 which receives the sleeper is hinged to the support 20 and urged in the direction f by a spring 41. A bearing plate 43, carrying rods 44 which slide in guides 45 mounted on the frame 33 and have secured to their upper ends ropes 46 wound on the drum 47, is located directly below the end of the beam when the latter has been pivoted through 90 degrees to lie on the longitudinal axis of the track. Rotation of the drum in the direction g causes the forward end of the beam to rise and unlocks the lock 38 which allows the member 37 on which the beam 17 is mounted to pivot with respect to the frame 33 so that the sleeper is pressed up against the rails 5, 6.

Abstract: 1,017,551. Time switches. W. HOLZER. Nov. 12, 1962 [Nov. 30, 1961], No. 42684/62. Heading H2B. The contacts of a time switch are operated by the relatively small timing motor by means of a cam driven through gearing which is not part of the timing train and which is coupled and uncoupled to effect closing and opening of the contacts. A synchronous motor 1 drives an hour hand 15 via gear 13 slidably keyed on a hollow shaft 14, and a minute hand 16 via gear 10 and shaft 11. A spring 20 tends to urge gear 13 into engagement with a pinion 34 but is restrained by a lever 22 pivoted at 25 on a disc 26 rigid with shaft 14 and having one end 21 engaged in a groove 19 in the bushing of gear 13 while the other end 23 normally wipes over tracks 24 and 44 on setting discs 29 and 28, respectively. Tracks 24 and 44 extend mutually to cover 360 degrees (Fig. 2, not shown) and a pin 46 on disc 29 moves in an arcuate slot 45 in disc 28 such that rotation of disc 29 by means of knob 33 first in one direction and then the other adjusts the overlap of tracks 24 and 44 leaving a selected sector free of either track. As lever 22 is driven round the end 23 drops off track 24 at the preset " on " time and gear 13 is slid into mesh with pinion 34 to rotate cam 37 via gears 35, 36. Cam 37 winds a spiral spring 40 and after closing contacts 38, 39 engages an abutment pin 42 where it is held stationary against slip of a friction clutch 43. When end 23 of lever 22 rises on to track 44 at the preset "off " time the gear 13 is withdrawn from pinion 34 and the spring 40 restores cam 37, thereby opening contacts 38, 39. Abutment pin 42 also determines the rest position of cam 37 such that it has to cover a certain distance before closing the contacts; this ensures that the contacts are not operated by rapid movement of the discs through the switching position while setting them. Overlapping arcuate holes 48 (Fig. 2, not shown) in the discs 28 and 29 expose to view a further disc (not shown) with coloured or luminous time interval markings. In a modification (not illustrated) the lever 22 carries a member which engages the indicator disc to move it while the contacts are closed to shown the time left until switching off takes place. A time dial 49 is mounted between a transparent cover 17 and the discs 28, 29.
