Title: Improvements in aircraft pressure cabins
IPC: B64D13/04
Filed: 1940-06-28
Abstract: 544,227. Ventilating and conditioning air in aircraft GENERAL AIRCRAFT, Ltd., WILLIAMS, D. L. H., and CROCOMBE, F. F. June 28, 1940, No. 11016. [Class 137] To obtain a supply of air requisite for proper respiration in the pressure cabin of an aircraft, air is circulated in a closed circuit through the cabin and an air conditioning plant involving the absorption of carbon dioxide and the replenishing of the oxygen used. As shown, air is drawn by a pump 10 from an opening 7 in the rear of a sealed cabin 3 and is forced through an air conditioning plant 12 in which it is filtered, heated or cooled, humidified or disinfected, the carbon dioxide being removed by lime or carbon. The purified air is returned to the cabin through trunk 13 and branches 14 with outlets 15 over the seated passengers. Oxygen from a reservoir 16 is discharged into the cabin through a valve 17 which operates should the cabin pressure drop below a predetermined level. A relief valve 18 which automatically opens with excess pressure may be the kind described in Specification 543,608. Instead of conditioning the air for a separate compartment, each member of the crew may be provided with a breathing mask. Specification 10161/39, as open to inspection under Sect. 91, also is referred to.

As shown in Fig. 2, the device comprises an oil reservoir 6, a box 7, containing the pressure and wiper pads, and a removable used oil receiver 8. The tape passes over a pulley 9, and oil drips on to it from a pipe 11 before the tape passes through the box 7, entering and leaving through slots 19, Fig. 3. The box contains a pair of felt or like pads 21, and a pair of rubber pads 23, the lower and upper members of each pair being mounted respectively on a plate 14, which rests on screws 15, and on a plate 13 attached to a guide-bar 17. The plate 14 is suitably set by independent adjustment of the screws 15 and adjustment of the pressure exerted on the tape by the pads 21, 23, is effected by means of a rotatable knob 24, Fig. 2, having an eccentric groove 25 which engages a lug 27 fixed to the lid 12 of the box. Oil delivered from the pipe 11 is conveyed by the tape to the pads 21, and impregnates them, the tape being lubricated and cleaned by the pads, most of the oil being then removed by the rubber pads 23, and dripping into the box 8. The oil flows to the pipe 11 from the reservoir 6 through an adjustable needle valve 32 and a tap 36, after being filtered by a muslin bag 34. The tap may be automatically opened only when the tape is in motion, by means of a connecting link 45 between the actuating lever 46 of the tap and a centrifugal clutch member coacting with the pulley 9.

Abstract: 1,261,732. Geophysical surveying. BARRINGER RESEARCH Ltd. March 7, 1969 [March 9, 1968], No. 11625/68. Heading G1N. In apparatus for electromagnetic geophysical surveying, according to our feature of the invention a secondary wave is induced by the passage of the horizontal magnetic field of the electromagnetic wave through conductors in the earth, the components of at least one component of the secondary wave magnetic field, which are in phase and in phase quadrature with the unaffected vertical electric field of the electromagnetic wave being used to determine the exsistance and shape of conductors in the earth. According to another feature of the invention, the resistivity of the earth is determined from the ratio of the horizontal quadrature component of the electric field in the propagation direction to the vertical component of the electric field. As shown, an electromagnetic ground wave is transmitted from a station, and the measuring equipment is carried in an aircraft. An aerial 10 picks up the unaffected vertical electric field component of the electromagnetic wave, aerials 11, 24, 25 pick-up the three components of the secondary wave magnetic field and the components which are in phase and in phase quadrature with the vertical electric field component are applied via phase detectors 17, 18, 28, 29, 30, 31, referenced by signals from aerial 11, to a pen recorder. Either the aerial 11 alone or aerials 11, 24 together may be used, Figs. 2 and 3 (not shown). A quadrature horizontal electric field component, due to an aerial 12 towed behind the aircraft, may be determined and used to measure the resistivity of the earth, which is proportional to the square of the ratio of quadrature horizontal electric field component to the vertical electric field component. For more accuracy two sets of apparatus tuned to two different stations at right-angles may be used. The frequency of the electromagnetic wave determines the depth of penetration of the wave and by using a range of frequencies a more accurate depth profile is obtained. The source of the electromagnetic wave may be a lightening discharge.

Abstract: 775,932. Springs. GRINNELL CORPORATION. April 25, 1955 [May 4, 1954], No. 11843/55. Class 108(3). A spring hanger is adjusted by reference to a graduated scale 44 the spacing between each pair of graduations being substantially indicative of pre-selected increments of percentage increase and decrease in spring force which the hanger can be adjusted to exert, one of the graduations 60, Fig. 11, representing a base point of predetermined value, and an adjacent graduation 62 being spaced therefrom by an amount substantially equivalent to the preselected percentage increments of the predetermined value of the base point, each subsequent graduation being spaced from its preceding adjacent graduation by an amount substantially equivalent to the pre-selected percentage increment of the value of the preceding graduation. In practice, each graduation is positioned by taking the mean of the values calculated by applying the percentage increment, firstly to a decreasing spring force, and secondly to an increasing spring force, so that the scale can be used for making adjustments of load in a direction of either increasing or decreasing spring force, Figs. 4-6 (not shown). The spring hanger is similar to that described in Specification 723,145. It comprises a bell-crank 22 pivotally mounted at 14 on a U-shaped frame 10b. One arm of the bell-crank is connected to the load L, and the other arm is slotted to receive a sliding block 36 adjustable in relation to the slot by turning a screw 34. The block is pivotally connected to a link 56, the other end of which is connected to the outer end of a load supporting coil spring 52. The inner end of the coil spring is pivotally mounted on the frame 10b at D. By turning the screw 34 and adjusting the position of the block 36 by reference to the scale 44, the constant spring force exerted by the spring 52 through the linkage to the load L may be adjusted. In spacing the graduations to a value corresponding to the mean of an increase or decrease in load, a small error is introduced, the magnitude of which can be deduced from a chart, Fig. 10 (not shown).

An arrangement for producing electrophotographic half-tone pictures uses a raster and is suitable for both negative-positive and positivepositive processes. In negative-positive reproduction a source 1 Fig. 1, of illumination produces an image of a negative 2 on a photo-conductive surface 6 by means of a first objective lens 3, a field lens 5, and a second objective lens 7, a raster 4 being positioned in front of lens 5. For positive-positive reproduction, a positive 10, Fig. 2, is placed in front of lens 3 and second source 8 of illumination produces an image of raster 4 on mirror 9. The mirror 9 may be semi-transparent or pivotally mounted into and out of the ray path between positive 10 and photo-conductive surface 6. In the latter case. the positive 10 is first exposed with the mirror swung out of the position and then the raster 4 is exposed with the mirror in the position shown. The position of lens 3 is adjustable to vary the size of reproduction of the positive 10 with respect to raster size.
