A bucket wheel 5 is mounted on a jib 6 which is pivoted on the gantry together with a rod 11 which contacts a coaming or other part of the deck of the barge by wheel 13. In operation the angular position of rod 11 is monitored and the jib 6 rotated so that a predetermined relationship is maintained between the angle of the jib and sensor rod. Other constructions of the height sensor are described and a diagram of sequential movements of unloader and barges is given which it is stated optimizes the use of the installation Fig. 3 (not shown).

Abstract: 1529829 Pump control S ROSEN 24 Dec 1975 [24 Dec 1974] 52813/75 Heading B8T [Also in Division H2] The pump of a filling machine is controlled so that the speed of its intake stroke is greater than the speed of its discharge stroke, the latter speed being chosen according to the product and container handled by the machine. The pump is driven by a D.C. motor whose speed is dependent on the angular position of the motor shaft which, on reaching positions corresponding to the start of the intake or discharge stroke, causes a controller to apply a high or a low voltage to the motor (see Division H2). The intake stroke time may be reduced from 7À5 to 2 seconds compared with a known filling machine wherein each stroke has the same time of 7À5 seconds.

Abstract: 1410627 FET logic divider circuit CENTRE ELECTRONIQUE HORLOGER SA 21 Nov 1972 [22 Nov 1971] 53710/72 Heading H3T A logic circuit Fig. 9 works as a binary frequency divider and includes three complementary F.E.T. stages at least one having an output E which is permitted to float under certain conditions. It may also be selectively connected to the power terminals by F.E.T.s 5, 9 or 8, 10. An input signal I and internally generated signals A, D, F interact as follows. Assuming I, E to be 0 and A, D, F to be 1, then when I goes to 1 F.E.T. 12 terms on and conducts through F.E.T. 10 which is held on by A to make D go to 0. This turns on F.E.T. 9, and when I returns to 0, F.E.T. 5 goes on and E is connected to the positive terminal through 5, 9 so that E and F become 1. When I goes to 1 again, F.E.T. 2 turns on and since E holds on F.E.T.4, A is earthed to become 0. A being 0 turns on F.E.T. 13 and D becomes 1. When I again, goes to 0, F.E.T.1 turns on to make A become I, and A and D hold on F.E.T.s 10, 8 respectively to make E become 0 again, this being the assumed starting condition. Capacitors CA, CD, CE, CF provide the storage needed for dynamic operation. A static circuit is disclosed (Fig. 8, not shown) from which the Fig. 9 dynamic cicuit is said to be derived by deletion of F.E.T.s shown to be unnecessary by the truth table.

The dispenser  has a stop position 74 for preventing the release of further cans when the dispenser is in its dispensing position. In the embodiment described the dispenser is pivoted at 68 and coupled by links 78 to a manually operated key 26 which may be depressed when shaft 88 carrying blocking finger 92 is freed for rotation on the deposition of coinage. A plurality of side-by-side dispensing units, Figs. 2 and 3 (not shown), are controlled by common shaft 88, there being a finger 92 for each unit. On depression of key 26 the dispenser 66 is raised to receive the lowermost can from the shelf and the dispenser then pivots under the weight of the can to release it to the delivery tray. The rotation of shaft 88 by the extension 82 of the operated key disposes the other fingers 92 on the shaft so as to block the operation of any other key, and the simultaneous operation of two keys is prevented by a captive link system (136), Fig.12 (not shown).

Abstract: 1384809 Atomic frequency standards E JECHART 7 Dec 1972 [14 Dec 1971] 56510/72 Heading G1A [Also in Division H1] In an atomic frequency standard of the type in which radiation from a light source containing alkali metal vapour is passed through an absorption cell containing the same alkali metal vapour which is enclosed in a cavity resonator and subjected to a static magnetic field the output of a photo-detector being used to control the frequency of an oscillator feeding the cavity, the cell substantially fills the cavity resonator and follows its contours and has a concavity into which extends a projection of metal or of a material with a high dielectric constant. As shown, Fig.1, an electrodeless discharge lamp 1 containing Rb is energized by a coil 2 and is enclosed in a chamber 3 the temperature of which is controlled at an elevated value. The emitted light passes through a cell 4 comprising a glass bulb containing Rb vapour and a brake or buffer gas and is received by a semi-conductor photo-detector 5. The cell 4 and detector 5 are mounted within a cavity resonator 6 into which micro-wave radiation is coupled by a capacitor, formed by a plate 10 spaced from the end wall 8 of the cavity by a mica sheet 9, and a multiplier diode 11. The cavity is provided with a thermostat system and is surrounded by two coils 16, 17 which are energized to apply a static magnetic field to the cell 4. The cell 4 has two concavities 14, 15 into which extend two metal pins or screws 12, 13 the positions of which can be adjusted for fine tuning purposes. The pins enable a smaller cavity than normal to be used by changing the resonance mode.  In the operation of the system a crystal controlled oscillator (21) feeds the cavity (6) via a low frequency phase modulating stage (25) and produces a hyperfine structure transition (reversal of electron spin in relation to the nuclear spin) in the Rb vapour causing an increase in the light absorption. The output of the photo-detector is utilized to correct the frequency of the oscillator, the phase modulation being utilized to determine the sense of the correction. The D.C. component of the detector output is used for fine control of the temperature of the lamp enclosure thus keeping the light output constant. The temperature of the cavity is maintained constant by a thermostat providing current to heating windings. Additional temperature compensation is achieved by using the thermostat to adjust the power source to the magnetic field coils. Alternatively part of the heating coil current may be passed through the magnetic field coils. The ouput may be taken from a frequency divider stage (26) fed from the oscillator.

Apparatus for dip moulding a plastic or fluid substance comprises forming members 12 mounted on shaft 10 which is attached at each end to conveying members 18. A toothed wheel 48 is mounted at one end of the shaft 10, and a holder 34 is pivoted on shaft 10 from an open position (shown at top) to a closed position (shown at 12b) defining the mould cavity. Guide members 60, 62 and 64 keep the mould parts in the correct relative positions during the cycle. In operation driving wheel 20 mounted on shaft 22 turns clockwise. The former 12 has been heated to the required temperature for moulding and the holder 34 is dragged along guide means 60. As the chain conveyer 18 moves round wheel 20, former 12 hangs down but holder 34 is prevented from falling by guide member 64. When former 12 is over bath 54 containing the plastic or fluid substance, the bath is raised and the former coated.
