Title: Record carrier on which information is stored in an optically readable structure
IPC: H04N5/85
Filed: 1975-02-11
Abstract: 1508881 Automatic control of position and focus PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 11 Feb 1975 [14 Feb 1974] 5743/75 Heading G3R An optically readable record carrier of the kind having tracks formed by successive areas g, t Fig. 3 producing different responses to incident radiation has at least one surface which is provided with periodic deformations along the line of the tracks, in order to allow control of the focusing of a read radiation beam. The periodic length P of the deformations is substantially greater than the average period of the successive information areas g. As shown in Fig. 2, a rotating disc record carrier 1 bearing tracks 2 is interrogated by a light beam from a source 6 transmitted by a semi-transparent mirror 7 and an objective lens 8. The reflected beam passes through the lens 8 and mirror 7 to a detector 9 connected to a processing circuit 10 and a television receiver 11. The circuit 10 produces a high frequency information signal Si derived from successive areas g, t along the track, Fig. 3, and a low frequency control signal S c  resulting from thickness variations with a relatively long period P. The variations may be sinusoidal or linear. Changes in focus produce variations in the relative phase between the control signal S c  and a signal derived from fixed marks on the carrier, and phase difference signals are used to adjust the focal length of the lens system or the lens position. Alternative forms of the carrier are described with reference to Fig. 7 (not shown). The information tracks may be on the upper or lower surface, and either or both of the surfaces may be deformed. The tracks may be read by a transmitted or reflected beam. The system may be combined with a known track following arrangement in which transverse oscillations of the tracks enable a read light spot to be accurately positioned.

Title: Improvements in or relating to pulse radar systems
IPC: G01S7/288
Filed: 1945-03-09
Abstract: 597,094. Radiolocation. BAILEY, A. E. March 9, 1945, No. 6002. [Class 40 (v)] The invention relates to a pulse radiolocation system employing a superheterodyne receiver and in which reference oscillations at the receiver intermediate frequency are mixed with signals at intermediate frequency derived from echo signals, the Doppler shift being made use of to discriminate between moving and stationary reflecting objects. In order to maintain phase relationship between the radio frequency of the pulse transmitted oscillations and the reference oscillations, pulsed oscillations are derived from the output of the frequency changer stage of the receiver and employed to control the phase of the reference oscillation generator. In the drawing, a pulse transmitter 1 feeds an aerial system 2, 3. Common T and R working is employed using a receiver blocking device 4 which allows an attenuated transmitter pulse to pass and mix in a mixer 5 with oscillations from a local oscillator 6. The mixer 5 feeds two intermediate frequency amplifiers 7 and 9, the former feeding a second detector 8. The amplifier 9 is normally blocked but is gated by positive-going transmitter pulses fed to it over a line 10. Intermediate frequency pulses derived from the mixer 5 are thus allowed to pass only when in phase with the pulse recurrence frequency of the transmitter 1 and pulses derived from echo signals are blocked. The intermediate frequency oscillations which pass through the amplifier 9 are fed through a buffer amplifier 11 to a generator 12 of continuous reference oscillations running at intermediate frequency, the latter being locked in phase at the beginning of each pulse recurrence period. The reference oscillations from the generator 12 may be fed to the second detector 8 as shown or to a suitable stage in the amplifier 7. A device 13 detects the frequency produced by the beating due to the Doppler effect of the echo signals derived from moving objects with the reference oscillations and its output may be used to give an audible or visual indication, or a P.P.I. display. In the case where the indicator includes a C.R.O., locking pulses may be fed to it over a line 14 to synchronize the time base. Specifications 596,649, 596,650, 596,651 and 596,657 are referred to.

Title: Optical projecting apparatus
IPC: G03B21/11
Filed: 1946-02-27
Abstract: 630,073. Optical-projection apparatus. DIEBOLD, Inc. Feb. 27, 1946, No. 6083. Convention date, March 7, 1945. [Classes 97 (i) and 98 (i)] A film strip to be projected is held under tension against a curved stationary trans-, parent member in the focal plane of the projection lens. In the apparatus shown in Fig. 2 the casing 20 is recessed at the front to support a viewing screen 22 and has a large circular aperture in the top, surrounded by an annular shoulder 37 in which rests a rotatable plate 27. A lamphouse 41 is secured beneath the plate and liglit from the lamp 47 passes through the aperture 38, is reflected from the mirror 39 through a heat filter 54 and a condenser lens combination 51, 52 and is reflected from a mirror 59 through the projection lens 60. In front of the condenser is the transparent film support member 55 (see also Fig. 4) secured to members 103, 105 which may enter holes in the plate 27 to provide the alternative positions shown for the member 55 according to whether the film is spooled with its emulsion surface inwards or outwards. In the casing, a mirror 74 silvered on both surfaces 74a, 74b is pivoted at 75 and may be retained by a spring catch in either of the positions shown. In one position the light beam from the lens 60 is reflected from a fixed mirror 73 on to the surface 74a and thence to the screen. 22. In the other position the beam is reflected from the surface 74b directly on to photographic paper contained in a holder 98. The sheets are perforated and exposed sheets are torn away by pulling tabs 101. When projecting in this latter way the plate 27 is rotated through 90 degrees from the position shown in Fig. 2 to remove the lamphouse 41 from the light beam. The film spools 30, 32 are mounted on spindles 28, 29 geared to electric motors 63 which tend to run in opposite directions, the actual direction of film wind being determined by the relative current supplies to the two motors as described in Specification 608,740. In a modified apparatus the guide rollers 114, 115 are mounted on pivoted solenoid operated arms by means of which the film is lifted off the plate 55 while it is moving.
