Title: Improved Line Follower.
Inventor: DIPROSE KENNETH VICTOR
IPC: G06K11/00
Filed: 1965-12-10
Abstract: 1,167,149. Photo-electric line follower. HANCOCK & CO. (ENGS.) Ltd. Dec. 5, 1966 [Dec. 10, 19651, No. 52530/65. Heading G1A. In a photo-electric line follower the photoelectric device has a small field of view which remains coincident with a scanning spot of light projected on to the substrate: the scanning path may be circular or a straight line. In Fig.3 light from a lamp 21 after passing through aperture 23 is brought into a parallel beam by lens 27 for passing through a Dove prism 28 and then focusing by lens 32 to form a spot upon the substrate 33. By rotating the Dove prism about an axis 37 offset from the axis of the condenser lens 24 and aperture 23, the light-spot makes a circular sweep over the substrate. Light reflected off the substrate returns via the Dove prism to be deflected by a Swan block - two prisms, one of which is half silvered at their interface 26 - on to the photo-electric device 36 which may be a phototransistor. In other arrangements the reflected light is deflected by a half-silvered mirror Fig. 2 (not shown) or an apertured mirror Fig. 1 (not shown).

Title: Solid state tuner
IPC: H03D7/12
Filed: 1967-11-21
Abstract: 1,147,507. Tuners. STANDARD KOLLSMAN INDUSTRIES Inc. 21 Nov., 1967 [27 Sept., 1967], No. 53001/67. Heading H3Q. A tuner has at least one stage with an inductor tuned by a varicap diode, and a voltagecontrolled switching diode for connecting a second inductor in parallel with the first. Fig. 1 shows the tuner section of a television receiver capable of receiving two V.H.F. bands. Tuning is effected by potentiometer 127 which controls the voltage on varicap diodes 14, 37, 39 and 68. Waveband switching is performed by switch 122 (which may be ganged with the tuning control and detent operated) which makes diodes 45, 42, 44 and 73 conductive or non-conductive. The aerial input at 10-1 is applied to the R.F. amplifier transistor 24 through a band-pass circuit. The inductors 12, 21 which tune with the varicap diode 14 are shunted by a further inductor 17 when diode 45 is made conductive for the higher-frequency band. The R.F. amplifier 24 is coupled to the mixer 51 through another band-pass circuit which comprises a tuned circuit (inductor 32 and varicap diode 37) coupled to a second tuned circuit (inductor 34 and varicap diode 39) by means of a common inductive impedance 31. For the higherfrequency band diodes 42 and 44 are made conductive to put tuning inductors 46 and 47 and common-impedance inductors 48 and 49 in parallel with the low-frequency circuit. The output is fed to the mixer 51 via the coupled winding 35. The local oscillator 62 is tuned by varicap diode 68 and series inductors 70 and 71, the latter being shorted by diode 73 for the higher-frequency band. A parallel arrangement of switched inductors may however be used as for the R.F. stages. For U.H.F. reception a separate U.H.F. tuner (Fig. 5, not shown) converts these signals to the I.F., amplifies them and feeds them through a capacitor (206) to transistor 51 which then acts as an I.F. amplifier. In the U.H.F. position of the selector switch (210 in Fig. 5, not shown) power is applied to the U.H.F. tuner and disconnected from the V.H.F. tuner and local oscillator. In the V.H.F. position these power connections are reversed and a further diode (211) made conductive to short the output from the U.H.F. tuner.

Title: Prevention or reduction of leakage from tankers or other ships
IPC: B63B25/12
Filed: 1971-11-17
Abstract: 1352895 Oil tankers SVENSKA ENTREPRENAD AB SENTAB 17 Nov 1971 [23 Nov 1970] 53396/71 Headings B7A B7S and B7M In order to prevent or reduce leakage of oil from a tanker in the event of collision damage, shields 3 separate the main cargo space 10 from spaces 4 at the sides of the tanker. The spaces 4 and 10 communicate only at the bottom of the tanker through permanently open openings. In use, the oil cargo 6 floats on a water charge 7 which also occupies the spaces 4. Alternatively, Fig. 5 (not shown), the oil cargo may occupy both the spaces 4 and 10. Thus, if the side of the hull is holed and the spaces 4 initially contain water, no leakage will occur, Figs. 2a and 3a (not shown). If the spaces 4 contain oil cargo, leakage will occur only to the extent necessary to allow the water level in the cargo space to reach the bottom of the shields 3. If the bottom of the hull is holed and the tanker contains an initial water charge, no leakage will occur. If the tanker contains only oil, leakage will occur only to the same extent as occurs with bottom holing of a conventional tanker. Any pressure acting on the shields is transmitted to the hull by vertically extending frame ribs. The shields may be formed of sheets of flexible steel or of rubber or plastics. In the latter case, the shields may include wire mesh which is earthed to the hull. The tanker may be double hulled. In a modification, Fig. 6 (not shown), the main cargo space is divided into three compartments by longitudinal bulkheads. In this case, the bottoms of the outer compartments are upwardly and outwardly inclined and the lower ends of the shields extend inwardly with a similar inclination to extend into the lower parts of the outer compartments.
