Patent GB-967481-A (GB)
Abstract: 967,481. Recording-apparatus. JERSEY PRODUCTION RESEARCH CO. July 23, 1962 [Sept. 7, 1961], No. 28213/62. Heading G1J. [Also in Division H4] Apparatus for photographically recording a 'transient electrical signal comprises a mirror galvanometer 14 responsive to the signal and positioned to reflect light from a long filament lamp 11 behind a stepped-density light filter 12, so that an image of the filter falls on a light shield having an aperture and light passing therethrough is intercepted by a photo sensitive medium on a drum 17 which moves transversely both to the path of the light and to the path of oscillations caused by the galvanometer, the length of the aperture along the path of oscillation being equal to the corresponding dimension of each step of the image. A spherical lens 13 concentrates light on the mirror of galvanometer 14 and a lens 15 adjacent a slit in the front of housing 16 condenses the filter image to a line image which is then focused on the film. As shown, the filter may proceed through four shades of grey from clear at one end to black at the other. In effect six ranges of amplitude are stacked within a single channel 18 and each of the five boundary lines between different shades presents a graph-like record of the signal. Alternatively the filter may be clear in the centre and proceed through three shades of grey to black at each end or the steps of the filter may be coloured, negative deflections passing through shades of one colour and positive deflections through shades of another colour. An oscillating line image of stepped light intensity may be produced by a cathode ray tube, having its grid fed with a stepped voltage pattern and, in synchronism therewith, the sum of a sweep voltage and the signal voltage applied to horizontal deflection plates. Multiple sets of apparatus may be adapted to provided multi-channel records suitable for presenting seismograph records for use in geophysical exploration.

Title: Fuel storage tanks
Inventor: STUART GRAHAM MANSFIELD
IPC: B67D7/00
Filed: 1998-04-21
Abstract: An air transfer valve is disclosed comprising a housing (8) having an inlet (21) and an outlet (22), the outlet being controlled by a first non-return valve (28, Fig 3) which is biased to its closed position and the outlet being controlled by a second valve (30) which is normally in its open position, the first valve being caused to open by an increase in air pressure within the valve but closing in response to reduced pressure. The valve is intended to be fitted into a fill pipe (1) of a fuel storage tank so that the outlet communicates with the tank ullage through an aligned hole in the wall of the fill pipe. In this situation, the valve transfers air from the fill pipe into the ullage and reduces turbulence which would otherwise cause excessive generation of vapour during tank filling. Preferably, the second valve (30) is a float operated valve closing to prevent liquid passing directly to the head space. Preferably, the venturi effect of liquid passing through the fill pipe (1) assists closing of the first valve (28) after the excess pressure has been transferred. Preferably, the fill pipe includes a float operated, overfill, shut-off valve (140, Fig 4).

Title: Distributed Method of Communications Resource Allocation
Inventor: CHAMBERS CHARLES
IPC: H04W72/08
Filed: 1996-11-20
Abstract: In a mobile satellite communications system, a number of stations 12 transmit messages through the same satellite transponder. Each earth station 12 receives information about messages waiting for transmission at the other earth stations 12, and determines the transmission timing of the messages so that they do not overlap at the satellite 14. Where acknowledgement of the messages by mobile terminals 16 is required, the timing of the acknowledgements is controlled so that peaks in acknowledgement traffic are spread in time relative to peaks in message traffic. This is done by transmitting a delay time to each mobile along with the message. Mobiles transmit an acknowledgement on the elapse of this delay.
