Title: A process and an apparatus for the preparation of sulfuric acid
Inventor: SCHOUBYE PETER CARL SEHESTEDT
IPC: C01B17/80
Filed: 1983-03-24
Abstract: In the preparation of sulfuric acid, a 240-330 DEG C hot gas stream containing SO3 and H2SO4-vapour in a total amount of up to 10% b.v. and up to 50% b.v. of steam, the ratio steam/SO3 being at least 1:1, is passed upwards through a plurality of externally cooled, vertical, acid resistant tubes (7) in a heat exchange tower for condensing sulfuric acid. The tubes are cooled with air introduced through an inlet opening (12) in the upper part of the tower and discharged through one or more exit openings in the lower half of the tower. By regulating cooling air velocities and levels from the bottom of the tower of discharging the cooling air the cooling is regulated so as to determine the discharge temperature T4 DEG C by the formula T4>125+6 alpha + beta +0.2(T1-Td> (where  alpha  is the %b.v. content of SO3+H2SO4-vapour in the feed gas,  beta its % b.v. content of steam, T1 its temperature in  DEG C and Td its dew point for H2SO4-vapour in  DEG C). Sulfuric acid is condensed on the inner tube walls as a film of liquid flowing downwards and in contact with the hot feed gas is concentrated to 93-98% H2SO4. <IMAGE>

Title: Mud pulse valve for measurement-while-drilling system
Inventor: ESTEP JAMES WILSON
IPC: E21B47/18
Filed: 1983-04-14
Abstract: A valve for a measurement-while- drilling (MWD) system is disclosed that uses a cylindrical valve member 56 that passes through a valve member guide 42 that carries a seal 78 in sliding engagement with the cylindrical valve member 56. A longitudinal opening extending from the end of the valve member to laterally extending openings 80 keeps the pressure on one side of the seal equal to the pressure below the valve member. This is downstream pressure when the valve is closed and upstream pressure when the valve is open. By having the area of the valve seat 47 that is contacted by the valve member 56 substantially equal to the area of the seal, the valve member will be substantially balanced when open and when closed. The valve discharges drilling mud from the drill string to the annulus to create pressure drops in the pump pressure at the surface. <IMAGE>

IPC: H01H17/16
Filed: 1983-07-05
Abstract: An electric pull-operated switch comprises a contact operating block part 20 secured to its cover part 10. The switch is operable by compression of a spring 46 as a drop cord 16 is pulled and so as to rock an actuator plate 24 until a stud 36 goes over-centre along a slot 32 within the actuator plate. The stud is at the free end of a major limb 38 of a link 40. The drop cord 16 is attached to a pin 44 at one end 42 of the major limb 38. The minor limb 50 of the link 40 carries at its free end 54 a part 56 that is effectively reciprocable on successive operations of the switch through an aperture 60 in the end of the cover nose portion 12.

Patent GB-2126688-A (GB)
Title: Axially resilient engine piston
Inventor: SLEE ROGER HARVEY
IPC: F02B3/06
Filed: 1983-09-09
Abstract: A piston (10) for a diesel engine is formed with a crown insert 24, which can be axially depressed against spring 30 at a predetermined cylinder pressure. During the compression stroke combustion bowl (21) has a lesser volume until the cylinder pressure reaches that at which fuel ignition takes place. The volume of the combustion bowl is then increased to reduce the maximum pressure in the cylinder. The volume is again decreased during the expansion stroke. This has a number of beneficial effects on the engine including reducing the stress on the engine parts and allowing increased level of pressure-charging. In other embodiments coil springs are used and the whole piston crown is resiliently mounted relative to the remainder of the piston. <IMAGE>

Title: Data capture system
Inventor: TURNER JOHN DYSON
IPC: G07B15/06
Filed: 1985-01-23
Abstract: The system involves the fitting of Electronic Number Plates (ENP's) to all road vehicles with roadside interrogators (outstations OS) and central control equipment to collect and validate vehicle identity data before passing it on to an accounts processing system AP. The system is organised so that there are a number of vehicle data processing devices (Data Validators DV) which receive data from the outstation units (OS) interrogated by a communications controller (CCL). Each Data Validator (DV) is allocated a discrete subset of all vehicles in the system to enable vehicle location checking to be maintained as the vehicles move through the system. Any apparent error in vehicle data is passed on to a supervisory processor which checks if the error can be explained. This provides a powerful vehicle location consistency check and fraud identification system allowing speedy detection of fraud, stolen cars or electronic number plates. <IMAGE>

Title: Testing fuses
Inventor: BENDALL COLIN
IPC: G01R27/02
Filed: 1985-10-08
Abstract: A security fuse arrangement for a fail-safe control system has duplicated fuse-blowing circuits (4A,4B) each coupled to a power supply line (1) containing a fuse (2) and operable in response to a signal from a respective one of two duplicated processors (A,B) to cause a fuse-blowing current to be passed through the fuse (2) and a respective fuse-blowing path (3A, 3B) in the event of a control system fault. The processors (A,B) are programmed to test periodically the ability of each processor (A,B) to energise both of the fuse-blowing circuits (4A, 4B), and the ability of each fuse-blowing path (3A, 3B) to carry a sufficiently large current to blow the fuse (2) independently of the other path (3B,3A). This test is carried out by causing each circuit (4A, 4B) singly and in alternation to pass a current through its associated path (3A, 3B) for a time interval which is insufficiently long to blow the fuse (2), and then monitoring the decay of the voltage across a resistance in the path (3A,3B) due to capacitance in the circuit (4A,4B). <IMAGE>

Filed: 1985-12-06
Abstract: Problems arise with co-sited radio communication apparatus on ships, for example, due to the presence of wide band noise generated by a transmitter interfering with a co-located receiver. Radio communication apparatus is provided comprising a transmitter including a wide band noise limiter positioned between an exciter/modulator (1) and a power amplifier (6), the wide band noise limiter comprising a first mixer (2) fed from the exciter/modulator, a band-pass filter (4) fed from the mixer (2) with a signal corresponding to the resonant frequency of the filter (4) and a second mixer (5) fed from the filter and arranged to feed the power amplifier (6) of the transmitter, the mixers being fed from a common local oscillator (3) the output frequency of which is selected in dependence upon the transmitted frequency so that the frequency fed to the band-pass filter (4) remains constant in the presence of output frequency variation, whereby the band-pass filter (4) is effective to suppress wide band noise which would otherwise be significant in a frequency band extending to each side of the transmitted frequency. The amplifier output is fed to an antenna 7 via a further filter 8. <IMAGE>
