Title: Proportional on/off valve
IPC: B61L13/00
Filed: 1973-06-04
Abstract: 1403890 Fluid-pressure servomotor systems UNIFLO SYSTEMS CO 4 June 1973 [2 June 1972] 26580/73 Heading G3P [Also in Division F2] The supply of air Pd to a turbine vortex thruster section 10 in a track 11 for levitated vehicles is controlled by a fluid actuated diaphragm 30 which is displaced from the end of an air inlet duct 16 to an extent determined by the displacement of a second diaphragm 32. Moulded lugs 33 on the latter maintain a space 38 between the diaphragms communicating with the duct 16 through passages 37 and an aperture 42. The second diaphragm is maintained in the position shown by springs 55 and air-pressure from a source 62 which is cut-off when a vehicle is approaching the section at the correct speed. Air in the space 38 now displaces the diaphragm 32 to the right expelling air from a space 53 through a bleed orifice 61 until a valve 60 is closed in response to a signal from a vehicle detector 65 to arrest further movement of the diaphragm. If a levitation signal now appears at a port 48, an amplifying valve 46 applies pressure to a diaphragm 44 to cause a valve 43A to close the aperture 42 and connect the space 38 to atmosphere. The diaphragm 30 is thus opened to an extent determined by the diaphragm 32. A further pressure source 63 maintains the diaphragms in the closed position if the approaching vehicle is inadequately spaced from the preceding vehicle. Specifications 1351970, 1403888 and 1403889 are referred to.

Title: Process of obtaining aromatic hydrocarbons
IPC: C07C2/86
Filed: 1929-09-03
Abstract: 335,353. Ramage, A. S. Sept. 3, 1920. Aromatic hydrocarbons, such as benzene, toluene, xylene, are produced by contacting a mixture containing unsaturated hydrocarbons, such as may be obtained by dehydrogenating light weathered products and casing head gasoline vapours over ferric or cupric oxide, with carbon monoxide and hydrogen, for instance, water gas, with metallic iron at 1000-1500‹ F. at atmospheric pressure. The catalyst is maintained active by the presence of excess hydrocarbon. The reacting gases should, if necessary, be initially freed from saturated hydrocarbons by passage over cupric or ferric oxide. In an apparatus for carrying out the process, the gases are passed through a series of tubes filled with iron powder or flakes, arranged in manifolds and heated by burner 4. The reaction gases are freed from condensable aromatics by a condenser 5 and separator 6, and are scrubbed by wash oil in a tower 8, residual gases 14 passing to a holder. The washer oil is pumped, preferably via heat interchange 11 to a still 12, from which the volatile constituents are distilled to a condenser 13 and receptacle 15, and there preferably mixed with the condensate from separator 6. The oil from the still 12 passes via the heat exchanger to the top of scrubbing tower 8.

Title: Packer unit for well blowout preventer
IPC: E21B33/06
Filed: 1975-06-24
Abstract: 1512657 Wells &c. HYDRIL CO 24 June 1975 [26 June 1974] 26790/75 Heading E1F An annulus of elastomeric material 34 in a well blow-out preventer packer unit is differentially anchored about the longitudinal packer axis 40 with the object of reducing the stress levels in the material 34 during its inward displacement towards the axis 40. The material 34 is anchored at longitudinally extending webs 31, 33 of metallic inserts 30, 32 which are generally circularly spaced about the axis 40. Webs 31 may anchor the material closer to the axis 40 than webs 33, as shown, and the inserts 30, 32 may also have end plates 44, 45 and 52, 53, the plates 44, 52 moving closer to the axis 40 on inward displacement of the packer. Plates 44 may have inward side extents 47 formed so that the plates 44 interfit as the packer is closed (Figs. 4, 5 show the packer partly closed). Radial grooves e.g. 70 may be formed in the material 34 beneath the spaces between adjacent plates. However, as the packer is closed the material 34 may be forced into a tapering space formed by the facing sides 48, 49 on adjacent plates being relatively angled. In another embodiment, the plates 45 may be formed with shoulders which, on closing the packer, closely circumferentially overlap radially outwardly facing edges of plates 44. Alternatively, the inserts may be located in two concentric circular paths, each plate, on closing the packer, engaging its adjacent plates and each outer plate circumferentially overlapping two of the inner plates. In further embodiments, the webs of all the inserts are spaced at the same distance from the axis 40 and the inserts all have wedgeshaped plates, but the plates are of differing size in suitable sequence, or the webs are differently offset relative to the radial axial planes bisecting the plates, such that the circular spacing between adjacent pairs of webs varies and more material 34 flows between certain pairs than other pairs as the packer is closed.

Abstract: 1383057 Square root extractors ITT INDUSTRIES Inc 6 July 1972 [8 July 1971] 27227/74 Divided out of 1383056 Heading G4G The mass flow rate of a fluid through a pipeline is determined by multiplying a density signal and a differential pressure signal, and deriving the square root of the product. The differential pressure across an orifice in the pipeline is applied to a cantilever beam 20 (Fig. 2) carrying a strain gauge resistor 22, 23 on each side, connected in a bridge circuit 25 (Fig. 3) which is fed with a current porportional to fluid density, measured by, e.g. the densitometer of Specification 1,328,888 and fed in as a voltage signal at terminal 26. Hence the bridge output at terminal 26. Hence the bridge output at terminal 27 is proportional to the square of the mass flow rate, and is fed to a computer (Fig. 4) where its square root is obtained as the frequency of a pulse train and the pulses are counted to produce a digital indication of the total fluid mass flow. The input current signal at terminal 163 (Fig. 4) is integrated at 166 to produce waveform A (Fig. 5) and also inverted at 165 and integrated at 167 to produce waveform B, the integrators being controlled through FETs 216, 203, 234, 249 and 261, 267 by gating signals from switching circuit 179. The waveforms A, B are added at junction 265 to form waveform C, which is integrated at 168 to produce waveform D. The maximum and minimum peak valves of waveform D are sensed by threshold detectors 282, 283 whose outputs set and reset a flip-flop 178 to produce a pulse train which controls the switching circuit 179 and is therefore proportional to the square root of the input current signal, and is integrated at 162.
