Title: Monitoring an aerosolization unit
Inventor: HIERTA LARS JOHAN
IPC: F16N7/32
Filed: 1968-07-23
Abstract: 1,208,054. Spray producers. EATON YALE & TOWNE Inc. 23 July, 1968 [8 Sept., 1967], No. 35188/68. Heading B2F. [Also in Division F2] The performance of an aerosolisation unit 10 is monitored and controlled by a fluid signal which is a function of either the liquid level of a reservoir 14 of the unit or the pressure at the outlet thereof. A source 24 of pressurised air is connected to the reservoir 14, via a conduit 36, a restrictor 38 and a conduit 34; and is connected to a fluidic interaction chamber 26, which is preferably an "AND" gate and provided with an input channel 28. When the fluid signal is a function of the liquid level of the reservoir 14 a channel A of the gate 26 is connected to the reservoir 14 by the conduit 34 and flow therethrough varies in accordance with the level of the liquid in the reservoir. The fluidic control signal passes through the channel A into the gate 26 and through an output channel 30 therein. When the fluid signal is a function of the pressure at the outlet of the unit 10, a channel B of the gate 26 is connected to the outlet, via a conduit 40 and a line 22. The fluidic control signal passes through the channel B into the gate 26 and through the output channel 30. If the level of liquid in the reservoir is below a pre-determined level or if the pressure at the outlet of the unit 10 is reduced, the signal received by the gate 26 will be decreased and the output therefrom will be switched from the output channel 30 to an output channel 32. At the same time a pressure-switch opens and an alarm is activated. In a modification as shown in Fig. 2 two interaction chambers are used and comprise a converted "OR" gate 42 and an "AND" gate 44. A restrictor 50 is provided in line 52.

Title: Improvements in or relating to radio apparatus for indicating distance
IPC: G01S13/34
Filed: 1947-12-31
Abstract: 661,177. Radiolocation. PHILIPS ELECTRICAL, Ltd. Dec. 31, 1947 [June 23, 1939], No. 35191/47. Drawings to Specification. [Class 40 (vii)] In a frequency-modulated radar system, wherein the received reflected frequencymodulated signal is mixed with the signal then being transmitted to derive a beat signal whose frequency is a measure of the range of the reflecting object, the amplifier for amplifying the beat signals is such that its gain increases with the frequency of the signal applied thereto, whereby the signals received from the more distant objects are amplified more than those from the nearer objects. The amplifier may also include a high-pass filter which prevents signals of the modulation frequency from being applied to the indicator at the output of the amplifier. The aerial system employed is preferably of the wide-band type, for example, a conical aerial may be used. The indicator used consists of a frequency-meter; for aircraft use, a cathode-ray tube display may also be employed. The cathode-ray beam is deflected in one direction in accordance with the output of the amplifier and is deflected in a perpendicular direction by a saw-tooth wave whose frequency bears a simple relation to that of the modulation frequency. Normally a smooth, approximately sinusoidal trace is produced on the cathode-ray tube screen; however, if there is any unevenness in the ground over which the aircraft is flying, the trace will lose its simple character and exhibit harmonics which owing to frequency-characteristic of the amplifier will be enhanced. The apparatus thus indicates the nature of the terrain over which the aircraft is flying. Specification 533,538 is referred to.

Abstract: 834,448. Optical-projection apparatus. PROJECTION OPTICS CO. Inc. Nov. 19, 1956 [June 21, 1956], No. 35276/56. Class 97(1) A projector comprises a projection head having two openings over which may be alternatively mounted a board carrying an adjustable lens, a plane reflector in the head providing a bent optical path between the openings, and support means for adjustably supporting said projection head on a light box having a source of artificial light for illuminating the object to be imaged. As shown in Fig. 6 the projection head comprises a casing, having a handle 106, secured to collars 40 sliding on columns 18. An external knob 48, Fig. 3, operates a shaft 45 which drives through helical gearing 47, 49. A shaft 51 which drives through worm gearing 53, 55 a transverse shaft 43 carrying pinions engaging racks 38 on the columns. The mirror 90 is pivoted at 92 and held by a spring 96 against an adjusting screw 94.The lower wall of the casing is formed by a panel 84 secured by fastenings 88 and carrying a mounting tube 76, with clamping device 82, for a lens 74. The front of the casing is closed by a transparent plate 102. The lens may alternatively be secured at the front of the casing, according to the focal length used and the range of focal lengths which can be accommodated may be increased by providing mounting panels with different mounting arrangements. Fig. 3 shows the projection head forming part of an episcopic projector. The supporting columns are carried in a base 116 the inclination of which may be adjusted by appropriately clamping by screws 142, downwardly urged spring plungers in tubes 138. A lamphouse 26 is carried on collars 22 and connected to the projection head by a bellows 32. The enlarged end of the lamphouse contains the lamp and concave reflector and other inclined reflectors surround an opening in the bottom of the lamphouse to direct light downwardly through it. An object may be held against this opening by a platform 126 carried on spring loaded links 128, 130. Cooling air from a blower 64 flows over the object, past the lamp out through louvres 72. A small pivotally mounted projector 145 projects a spot of light which may be used to indicate a desired point in the projected picture. In another arrangement the base 116 is dispensed with and the lamphouse 26 placed directly on the object to be projected. An alternative lamphouse for projecting transparent objects has a transparent illuminated upper surface.

In the arrangement of Fig. 1, the display is formed on two tubes. The right hand one gives a representation 10 of absolute altitude which consists of a fixed symbol 12 and a mobile horizon line 11 which when rotated relative to symbol 12 indicates the degree of bank. Line 11 is associated with mobile dotted horizon lines 13 marked at 10-degree intervals up to Œ180 degrees to indicate in association with symbol 12 the elevation angle of the aircraft. A height indicator 20 comprises a digital read-out derived from barometric, radio or radar instruments, the height measurements being sampled at intervals of, e.g. half-a-second to avoid blurring of the numerals. A similar digital read-out 41 denotes air speed and an associated read-out 42 denotes air speed error, a symbol 44, when aligned with a central dot 43 indicating that the aircraft is flying at a selected airspeed, displacement of symbol 44 indicating deviation from the selected air speed. A row of dots 32 represent vertical speed, the indicator being an extensible line 31 which when above the dots represents climb and when below, descent. Heading or track is denoted by read-out 50, in which the last digit is small to avoid confusion with air-speed numerals 41. An indication of side slip is provided by a mobile marker 62 movable laterally within a rectangle 61. A director display on the other tube comprises symbols 72 and 71, similar to the symbols 12 and 11, to represent the attitude of the aircraft in bank and elevation. Three bars 73, symbolizing an imaginary triangle with its apex on index 72 gives an indication, by distortion, of the errors in azimuth and elevation. In Fig. 2 (not shown) the vertical speed indicator is arranged as a semicircle of dots (33), an arcuate extensible marker (34) extending either upwardly or downwardly over the dots. Also arrows (21) supplement the height indicator (20) to indicate climb or descent. The airspeed indicator (40) reads in terms of Mach No. instead of airspeed and different forms of heading (50) and slip (60) are provided. In the embodiment of Fig. 3 (not shown) the director display includes an indication (80) of unexpired range.
