Title: Vehicle manoeuvre margin presenting display apparatus and method
IPC: G05D1/00
Filed: 1976-09-27
Abstract: 1519376 Indicating instruments PACER SYSTEMS Inc 27 Sept 1976 [26 Sept 1975] 40040/76 Heading G1J [Also in Division B7] A manoeuvre margin indicator for a vehicle, in particular a helicopter, comprises a first pointer 18 to indicate the speed of the vehicle, a second pointer 20 to indicate the instantaneous useful power of the vehicle engine(s), and comparator means 15 associated with the pointers to present a speed-power relationship appropriate to the prevailing vehicle and ambient conditions. A plate 10 behind the front glass 6 of the instrument carries speed and power scales 12, 14 associated with the pointers 18, 20 respectively. Behind a square aperture 11 in the plate 10 is a plate 15 marked with a set of curves 16 showing the power required for level flight as a function of speed, for a range of conditions. The point at which the pointers 18, 20 cross establishes the curve applicable. Thus in Fig. 1, by following the curve just below the intersection it can be seen that for a 10 knot speed, 76% of full power is needed for level flight, and for stationary hover, 85% power is needed. A rollerblind mask 26, Figs. 5 and 6, can be adjusted by a knob 24 to indicate the maximum power available. Thus in Fig. 5 the shaded area 29 indicates the excess power available for maneouvre. If the speed is reduced below about 18 knots in the Fig. 5 case, height loss will occur as there will be insufficient power for level flight. A third pointer 28 adjusted by a knob 64 is set to indicate the minimum speed for level flight. A contact 80 moving with the pointer 18 and contacts 82, 84, 86 moved with the pointer 28 energize warning lamps 70, 72, 74 to show whether the speed is above, at, or below this minimum speed. Audible warning tones may be used instead of the lamps. The power indication by pointer 20 and the position of the mask 26 can be automatically corrected for the effects of ambient pressure and temperature changes. The minimum speed indication by pointer 28 can be automatically adjusted to correct for rate of change of altitude.

Title: Control system for the supply of a fluid material and valve  means for such system

Abstract: 1411498 Valves PRODEF ENGS Ltd 19 Oct 1973 [25 Aug 1973] 40359/73 Heading F2V A valve for use in a system controlling the supply of fluid material to a spraying device comprises a valve body 11 having an inlet port 12 for fluid material from a pump and an outlet port 13 formed in an upstanding seat 14. The latter co-operates with a spring loaded closure member which, as shown, is formed by a slidable piston 16 having a resilient insert 18 and a sealing 0-ring 17, but in a modification (Fig. 2, not shown) is formed by a diaphragm (25) backed up by a piston (28). Since the closure member 16 (or 25) has a greater surface area exposed to inlet pressure at port 12 than to outlet pressure at port 13 the valve opens when the inlet pressure exceeds a predetermined minimum to permit flow of fluid material through outlet port 13 to the spray gun or a mixing chamber associated therewith. An additional inlet 23 is provided for the supply of a solvent or air purge via non-return valve 24. The compression of biasing spring 20 can be adjusted by a screw 22 acting on plate 21. Supply pump operation may be initiated by an air signal from a trigger controlled pilot valve. When the trigger is released air is directed from the pilot valve to above piston 16 to assist the biasing action of spring 20. Simultaneously the pilot valve causes supply of purging fluid to inlet 23.

Abstract: 1448844 Domestic water filtration apparatus DYNEK CORP 28 Aug 1973 [20 Nov 1972] 40490/73 Heading B1D [Also in Division Cl] A portable domestic water filtration apparatus comprises a container defining an unfilteredwater compartment 10 mounted next to a pump compartment 12, whereby unfiltered water is led through an opening 20 in the base of compartment 10 into the inlet of a pump 18 mounted within compartment 12 and then is fed (by tube 22 and fitting 24) from the pump outlet into a filter device 14 mounted within the compartment 10, from which filtered water leaves the container by means of a nozzle 16 integral with the filter device. The apparatus suitably provides an integral mounting 40 for a beaker 38 for collection of filtered water. The filter device may comprise a particulate filter material 72 (Fig. 3) for purifying the water held in a one-piece casing 64 by means of two porous filter discs 68, 70. Such a filter device forms the subject matter of UK Specification 1448845. The casing 64 and its integral outlet nozzle 16 may be formed of plastics material and the filter discs 68, 70 are suitably formed of polyethylene. The lower disc 68 is of relatively coarse filtering action, e.g. it contains apertures of c.a. 35 microns, whilst the upper disc 70 is of relatively fine filtering action, e.g. it contains apertures of c.a. 10 microns. The particulate material may be active charcoal, part of which may be coated with metallic silver or a silver salt, or an ion-exchange resin or a mixture of the two. The lower filter disc 68 has an aperture size chosen such that, in combination with a non-positive action pump, e.g. a centrifugal pump, it will stop the filtration upon its becoming clogged and thus may be chosen to occur at the same time as the particulate filter material becomes depleted. The casing may be clear plastics and a dye indicator may be used to indicate when ion exchange material, if present, becomes depleted.

A self-propelled harvester for tall crops comprises a topping unit 46 supported on a telescopic boom 48, divergent gathering arms 38 and a drum 36, which guide the crop to rotary cutters 34, rotary choppers 30, a fan 80 with outlet 82 to provide an initial separation of trash from cut crop, and an elevator 62 from which crop passes through a further blast of air from fan 84 (Fig. 17) before being deposited on discharge conveyer 70. The topping unit comprises a pair of divergent arms 52 with conveyers 54 and has a deflector plate 60 pivoted on a shaft 238 whereby the cut tops can be discharged on either side of the machine. The shaft 238 also supports flingers 58 which are rotated by a hydraulic motor in the same direction as the cutter disc 56. This drive is reversible and its direction depends on the setting of the plate 60. The flingers comprise triangular plates arranged in staggered relation. Downwardly inclined plates 234 deflect cut tops away from the machine. The inclinations of the boom 48 with respect to the frame and of the topping unit with respect to the boom are adjustable by hydraulic rams. The rear discharge elevator 70 is arranged to be pivotable about an axis 578 in order that it may discharge to either side of the machine or directly behind the machine. To this end, supporting frame members 620, 622 for the elevator are mounted to be capable of rotation around the air discharge opening 504 in the machine housing. The cutter and chopper unit 22 is mounted on the frame by a parallel linkage which enables the cutter height to be varied. The gathering arms 38 of this unit incorporate conveyers 42 which can be of either the slat or screw type.
