Title: Logarithmic calculators for astronavigational purposes
IPC: G06G1/12
Filed: 1949-12-31
Abstract: 691,310. Calculating-apparatus. BARTELSKI, J. M. June 22, 1950 [Dec. 31, 1949], No. 33449/49. Class 106 (i). In astronavigation from aircraft, a short interval, generally about four minutes, always elapses between the actual observation and the time of the fix. The invention comprises a logarithmic computer for calculating the change in altitude of a star during this interval so that the observed altitude can be corrected to the true altitude at the time of the fix. Calculations are based on the formulµ: (1) rate of change in altitude due to star movement= cosine latitude of the observer X sine azimuth of the star X constant, and (2) rate of change in altitude due to aircraft movement = cosine angle between flight track and star azimuth x aircraft speed X constant. Separate sections of the computer evaluate altitude change due to star and aircraft movement, and the results are added to provide the correction. The computer comprises a base disc a with a fixed reference arm f, and four superposed rotatable discs b-e. One section comprises the discs band c, disc c having a log. sine star azimuth scale and a reading aperture for a log. cosine aircraft latitude scale on the disc b which also has a log altitude change scale on its exposed periphery. The other section, comprising the discs d and e, is similar, disc e having a log. cosine track angle scale and a reading aperture for a log. speed scale on the disc d which again has a log. altitude change scale on its exposed periphery. In use, the scales on discs c and e are set against the reference arm f according to azimuth and track angle, the inner scales on discs band d are set in the reading apertures according to latitude and speed, and the two corrections are then read off the outer scales on the discs b and d against the reference arm. The reference arm f is fixed in the 4-minute position on a log time scale marked on the base disc a. A second reference arm g, adjustable over the time scale, is used for other time periods.

Abstract: 970, 321. Photographic enlarging apparatus. CAPS (RESEARCH) Ltd. Oct. 7, 1960 [Oct. 8, 1959], No. 34209/59. Heading G2A. A photographic enlarger has a light source, a film locating means, a magnifying lens system, and a mirror, arranged one above the other in that order along the same axis, the light source being below the printing bed and the mirror above it so as to reflect the light beam down on to the bed, the lens system and the mirror being movable for automatic adjustment of the focus. As shown, the light source is a lamp 18 and reflector 19. Following in sequence is a heat filter 20 and shutter 21, a gate 22 and the magnifying system 23. The light passing through the film in the gate, after passing through the magnifying system is reflected from a mirror 16 down on to a printing bed 17 on which the sensitive paper is laid. The magnifying lens system is described in more detail in Specification 970, 322. The gate is shown in more detail in Fig. 4, and has a fixed gate lens 54 and a movable condenser lens 56 in respective supports 53, 55. Lens 56 can be retracted by a foot pedal 50, against springs 57, to insert a microfilm 58, which is then clamped firmly against lens 54. Cooling air can be blown through channels 60, 61. The mirror 16 is mounted in a hood 15 carried by telescopic tubes 11, 13, so that its position can be adjusted. As tube 13 slides in tube 11, a wire 24 attached to it, which is looped over a system of pulleys, moves a weighted trolley 33 up or down. A roller 36 on trolley 33 bears against a cam surface 37 formed on an arm 38 pivoted at 40. Bearing against an upper surface of arm 38 is a rod 44 having an angled portion 45 which passes through a slot 46 in a fixed casing 47 to engage the magnifying lens system 23. Thus as tube 13, and hence mirror 16, moves, a corresponding movement is imparted to lens system 23, the shape of cam surface 37 being so designed that focus is always maintained. The shutter 21 is a yellow glass disc thinly aluminised so as to transmit about 10% of incident light. When in the obscuring position, enough light is transmitted to view the image on the sensitive paper, and it is then moved out of the way to make the exposure proper.

Abstract: 1385300 Carburetter choke control GENERAL MOTORS CORP 19 July 1973 [12 Sept 1972] 34485/73 Heading F1B [Also in Division F2] A vacuum responsive unit, for operating a carburetter choke valve (14), Fig. 1 (not shown) in response to inlet vacuum, has a chamber 70 formed by a cover 30, Fig. 2 closed by a spring- biased diaphragm 38 which moves to position the choke valve, a tubular extension of the cover being connectible to an engine intake vacuum source with a valve 80 between the extension and the chamber, an air bleed 98 arranged between the valve and the vacuum source so that with a pressure increase in the vacuum source there is a reduction in flow from the opening 98 to the source and a flow of air from the opening 98 to the chamber 70 which prevents material in the vacuum source from encountering the valve and an air filter 102 being arranged over the opening. Engine intake vacuum in chamber 70 causes diaphragm 38 to move guide 44 to the left thereby compressing spring 48 to bias arm 46 and link 52 to the left to move lever 22, shaft 18 and choke valve 14 in the clockwise direction to open the choke valve 14. When intake pressure increases valve disc 82 is displaced from O-ring 80 against resilient finger 84 to permit fluid-flow into chamber 70 and upon a decrease in manifold pressure the finger 84 presses valve disc 82 against O-ring 80 to restrict flow to chamber 70 to the  flow through a notch (96), Fig. 3 (not shown) in valve disc 82. Air is drawn continuously through opening 104, filter 102 and opening 98 so that when intake pressure increases the pressure in chamber 70 increases by a filtered air-flow from opening 98 to prevent foreign matter from being deposited in notch (96).
