Patent GB-1196264-A (GB)
Title: Timing Arrangements
Inventor: ANDERSON EDWARD WILLIAM
IPC: G01C21/00
Filed: 1966-07-07
Abstract: 1,196,264. Navigational computing apparatus. SMITHS INDUSTRIES Ltd. 7 July, 1967 [7 July, 1966], No. 1855/70. Divided out of 1,196,262. Heading G4G. [Also in Division G1] The description is substantially identical with that of the parent Specification 1,196,262 but the claims relate to the arrangement of Fig. 4 (identical with Fig. 5 of the parent Specification) for combining two signals K cos # and K sin # with a third signal V, representing velocity, to obtain signals representing V cos # and V sin 0, and integrating them to obtain the distances travelled by a craft in a northerly and easterly direction. As shown (Fig. 4), an A.C. signal K cos # is fed to a phase-rectifier 40 to produce a first output signal which is + or - corresponding to the sign of output and is fed to integrator 42, and a second output signal corresponding to the amplitude which is fed to amplifier 46 and switch 44. Amplifier 46 is also fed with a sawtooth voltage from integrator 47, and when these are equal the output from 46 is zero and switch 44 is opened. Hence the signal K cos # is fed in pulses whose durations are proportional to K cos # to an integrator 45, so that the signal reaching 45 is proportional to K<SP>2</SP> cos<SP>2</SP> #. This is added to a second similar input to integrator 45 proportional to K<SP>2</SP> sin<SP>2</SP> #, derived from an A.C. signal K sin #, and opposed by the sawtooth voltage from integrator 47. When the sawtooth voltage reaches the value K<SP>2</SP> cos<SP>2</SP> #+K<SP>2</SP> sin<SP>2</SP> #, i.e. K<SP>2</SP>, the output from integrator 45 is zero and detector 52 resets the integrator 47 to initiate another sawtooth wave. Hence the period of the sawtooth voltage is dependent on K<SP>2</SP> and therefore on K. A further switch 43 is operated by amplifier 46 with switch 44 to feed a velocity signal V to integrator 42 in pulses whose duration is proportional to K cos # and with a periodicity dependent on K. Hence the input to integrator 42 is proportional to V cos # and its output is the distance travelled in the northerly direction by a craft moving with velocity V at an angle # to the magnetic north. A similar network feeds a signal V sin # to an integrator 48 whose output is therefore the distance travelled in an easterly direction by the craft.

Title: Improvements in or relating to apparatus for separating oil fat, soap, and the like from trade effluents
Inventor: SMITH HERBERT
IPC: D01C3/00
Filed: 1954-01-27
Abstract: 756,230. Filters; gravity-separation apparatus; treating waste effluents. SHIRT, H. Jan. 27, 1955 [Jan. 27, 1954; Oct. 9, 1954], Nos. 2454/54 and 29147/54. Classes 46 and 111. Effluent or water to be treated enters at 20, Fig. 7, a trough 21 and passes under an over baffles 23 to an arcuate filter 26, Fig. 8, whence matter retained is brushed (27) into a trough 39 with a sloping bottom. Filtrate passes into a trough 32 and thence into the space between an inner wall 33A, Fig. 7, and an end wall 34 of a separating tank 22. The liquid flows under the inner wall 33A, the lighter constituents thereafter rising between wall 33A and a second inner wall 33, and the heavier constituents passing under wall 33 and over a baffle 35 into the next compartment Y where the separating process is repeated. Stiff scum (e.g. heavy fat in bacon-factory effluent) may be raked through openings 38 into the trough 39. Where the lighter constituents are free-flowing the openings 38 may be replaced by narrow horizontal slots. Heavier constituents finally emerge over an adjustable weir 13 into an outlet 36. In Fig. 9 the arcuate filter and brushes are dispensed with and compartments I; II are provided in an upright cylinder 41 by a diametral baffle 42 having a slot 43. On each side of the baffle the "inner walls" are provided by a hemi-cylindrical sheet 47, Fig. 12, contacting the baffle at 49 and spaced at 51 from the base of the cylinder 41, and a sheet 48 effectively spaced from the base of the cylinder 41 by an opening 52, these members together constituting a removable unit 46. Guide plates 50 keep the sheets 47 clear of the tank wall. Oil separating in the region between the inner walls 47, 48 may be absorbed in material such as wood wool or plastic filling contained in a wire cage 53 resting on brackets 54 inside each unit. Instead of the inlet 44, a grill may be provided in the removable tank cover 55. In Fig. 7 the space between the inner walls and the tank bottom diminishes in successive compartments. In Fig. 3 (not shown), lighter liquid flows through slots into a side compartment evacuated by a pump driven by a float-controlled motor.

Patent GB-679814-A (GB)
Title: Apparatus and method of coating
IPC: B05B5/14
Filed: 1948-01-28
Abstract: Surfaces are provided with thin, liquid coatings by subjecting the surface carrying spaced dielectric liquid particles to the action of an electrostatic field to cause the particles to spread upon the surface, the <PICT:0679814/III/1> <PICT:0679814/III/2> quantity of liquid being so small that the particles would not spread to form a continuous film in the absence of the flattening effect of the electrostatic forces within each particle. Preferably the coating is precipitated on the surface in an electrostatic ionizing field which also serves to spread the particles.  In the apparatus shown in Fig. 1, a web 26 passes between two induction nozzles 35 and 36 situated in a electric field produced by electrodes 11 and 12 supported on frames 8 and 9.  Streams of liquid dispersed in air at a low rate of flow are deflected by the field on to the web which passes on through the field when the coating flattens out to cover the surface.  The dispersion unit 37, Fig. 3, contains one or more vertical tubes 42 having a narrow aperture 44 and a lower end extending into a trough 46 containing liquid to be atomized.  A heating element 51 may be located below the trough.  A jet of air from pipe 48 atomizes the liquid from the nozzle 44 and the spray hits a baffle 58 which disrupts the larger particles.  As a result, the nozzle 35 issues a slow moving fine mist.  The flow in the electrostatic field is aided by the exhaust duct 19, Fig. 1.  Means for automatically regulating the rate of flow of the spray with the speed of the web to ensure uniform deposition are also illustrated and described.  Surfaces which may be coated include conducting and non-conducting material but, in the latter case, a conducting backing should be provided. Specified liquids which may be applied are mineral, vegetable and animal oils, molten or dissolved natural or artificial waxes, resins, asphalts, tars and certain organic solvents.  Specification 550,391 is referred to.

Abstract: 839,645. Valves. BUTLER, G. A. Jan. 28, 1957 [Sept. 24, 1956], No. 2999/57. Class 135. In a rotary cylindrical plug valve for the control of high-pressure fluids, comprising a valve body 10, Fig. 1, having a bore fitted with a sleeve 12 in which a slightly smaller diameter cylindrical plug 60 rotates to open and close a transverse flow passage 30, 32 through the body, the ends of the plug are sealed with respect to the sleeve by end seals supplied with plastic sealant material from reservoirs 80, 81 in which slide pistons 92 subject to line pressure. Each end seal comprises three annular plug grooves, the outer grooves being fitted with split pistontype rings 105 whilst the centre groove communicates with both reservoirs through radial sleeve ports 126, 128, vertical and annular sleeve grooves 120, 122 and oblique ports 123, 124 through the body walls. The vertical grooves 120 also communicate with arcuate horizontal grooves 132, Fig. 6, which through radial sleeve ports 133, 134 supply vertical inner sleeve grooves with sealant which when the plug is in its closed position overlap substantially C-shaped grooves 139, 141 in the plug surface to completely encompass the flow passage. When the valve is open, line pressure urges both pistons upwardly to unseat looseball valves 91 to supply sealant under pressure to the end seals. When the valve is closed, the upstream piston only is raised and the looseball of the downstream reservoir remains seated to isolate that reservoir. Sealant is then supplied to the end seals and the downstream grooves surrounding the flow passage. The upstream grooves surrounding the flow passage are ineffective to provide a seal since due to the clearance between the plug and sleeve, line pressure acts directly on this seal to balance out the pressure transmitted by the upstream piston.
