Patent GB-2237861-A (GB)
Title: Liquid propellant gun system
Inventor: BULMAN MELVIN JOHN
IPC: F41A1/04
Filed: 1986-07-08
Abstract: An annular piston, annular control valve, liquid propellant gun system, has a dual angle injection mechanism to provide both combustion chamber and bore gas requirements with a single injection control valve. The dual angle feature assures a stable combustion zone. The projectile is fixed by a frangible threaded tube 27 to a stub case 28 housing a booster charge 30, firing of which causes hot gases to pass into the combustion cave 120 forcing piston 38 forwardly to increase the pressure in pumping cavity 118 causing a belleville washer 206 to close passageway 77 and valve 36 to move forwardly, uncovering bores 126, 128, the aft-inclined (126) of which pass liquid propellant into the annular cavity surrounding the projectile. As pressure increases, a flexible lip 26a on the firing band 26 of the projectile is deflected to pass liquid propellant aftwardly of the projectile into combustion cavity 120. When the projectile has uncovered bores 128, liquid propellant is sprayed through these bores into the gun barrel 8, which propellant then burns due to contact with hot combustion gases. <IMAGE>

Patent GB-862321-A (GB)
IPC: H03B9/12
Abstract: 862,321. Pulse frequency - divider circuits. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Jan. 3, 1958 [Oct. 5, 1956], No. 30440/56 Class 40(6) [Also in Group XIX] A pulse frequency divider comprises a timing capacitor CC, Fig. 1, a pulse-repeating circuit including a two-terminal trigger device D (i.e. a device whose voltage/current characteristic exhibits a negative resistance region) for producing output pulses and altering the charge on the capacitor in one sense, and a restoring circuit including a timing resistor RT for altering the charge in the opposite sense, the arrangement being such that, when an input pulse triggers the device D, an output pulse is produced and the capacitor is so charged as to inhibit triggering by a subsequent input pulse for the period of time taken for restoration by current flow in the restoring circuit, the number of input pulses rendered ineffective corresponding to the required division ratio. The trigger device may be a transistor or, as shown, a gas-filled diode. In operation, a positive input pulse Vp will trigger the diode and charge capacitor CC, thus producing an output pulse at TL. When the diode extinguishes, at or before the end of the input pulse, the potential at TA is approximately Vp-Vm where Vm is the diode maintaining voltage, the diode being inhibited until this potential is reduced by the restoring current to Vp-Vs where Vs is the striking voltage. Restoring current flows from a datum voltage VD through output resistor RL, relatively large resistor RT to a negative bias voltage and the time constant of the restoring circuit may be such as to inhibit only one input pulse following each triggering, thus providing a division ratio of 2. A plurality of such frequency dividers may be coupled in tandem. The frequency dividers may be employed in data-storage apparatus (see Group XIX).

Title: Hydrogen occlusion in optical cables
Inventor: BARNES STUART ROBERT
IPC: G02B6/44
Filed: 1986-11-18
Abstract: In an optical fibre cable, hydrogen generated is absorbed by the incorporation in the cable of a silver substituted zeolite. The zeolite may be dispersed in a plastics material or in a water blocking compound with which the cable is filled. The optimum absorbing capacity is obtained with a silver substitution level in the zeolite of 15%. At this level a gel having 0.05 weight percent zeolite can absorb the hydrogen generated in a cable under average service conditions. <IMAGE>

Title: Bucket conveyor device for clearing stockpiles of bulk materials
Inventor: TOPSCH NORBERT
IPC: B65G65/06
Filed: 1987-01-29
Abstract: A device for clearing stockpiles of bulk materials has an endless conveyor with carrier buckets (7) each of which has at least one ploughshare-like guide face (12) equipped with a cutting edge (13) which penetrates and cuts away the material of the stock pile. The guide face is arranged at the leading edge of the floor (10) of the carrier bucket (7), and directs material removed from the stockpile onto the floor of the preceding bucket. To improve the filling ratio of the carrier buckets (7) whilst at the same time simplifying the construction of the carrier buckets, the inner edge of each guide face (12) defines an opening (15) in the carrier bucket of which that guide face forms part, enabling material removed by the guide face to pass onto the floor (10) of that bucket in addition to being directed onto the floor of the preceding bucket. <IMAGE>

Title: Electrostatic spraying apparatus
Inventor: GROCOTT AREND LEA
IPC: B64D1/18
Filed: 1987-09-01
Abstract: An apparatus is disclosed suitable for electrostatic spraying from fixed wing aircraft. The apparatus includes a linear electrostatic spraying nozzle 2, supported from the aircraft by brackets 8, and electrodes 4 placed near the nozzle's spraying edge 16 to intensify the electric field strength at the spraying edge sufficiently to produce ligaments of the liquid from the spraying edge. In order that the airstream due to the aircraft's movement does not destroy the ligaments, the sprayhead and the electrodes are positioned so that part of the airstream flows between them. The spray head and the electrodes are so shaped and positioned that when directed to spray in substantially the same direction as the airstream, a turbulence free wake is left in the region of the ligaments. The liquid reaches the edges by passing across a slot 18 from a distribution gallery 44, a conducting or semiconducting surface 20 being arranged within the slot. <IMAGE>
