Title: Improvement in automatic variable speed power transmission
IPC: F16H3/68
Filed: 1938-07-01
Abstract: 499,731. Variable speed gearing. CATT, F. W. C., and CATT, O. F. July 1, 1938, No. 19519. [Class 80 (ii)] Gearing automatically variable in accordance with speed and load comprises planetary worms 5, carried by a driving flywheel 3, and engaging a worm-wheel 6 fast to an intermediate driven shaft 7, rotation of the worms 5 on their own axes being variably braked by levers 13, carried by the flywheel 3, and having fibre or felt pads 13a, frictionally engaging brakediscs 35 splined at each worm-shaft 5. Braking pressure is automatically increased with increase in speed by centrifugal governors 36, mounted directly on the worm-shafts 4, and is reduced with increasing load by a spring or fluid coupling 17. As shown, the latter comprises helical springs 17 between alternating radial projections on a member 14 splined to the shaft 7 and a member 15 integral with the output shaft 16. As the spring-coupling yields under load, it causes a relative turning between a screw-member 18 on the output member 15, and a co-operating nut-member 19 splined on the shaft 7, thus resulting in axial movement of the nut, which turns the levers 13 and reduces the braking-pressure. The pitch-angle of the worms 5 is near the critical angle for irreversibility, e.g. about 7‹. Between the output shaft 16 and the final driven shaft 22 is a two-speed, neutral and reverse gear, comprising a sliding sleeve 27, having internal clutch-teeth 28, for direct-drive engagement with clutch-teeth 25, and also having a toothed wheel 29 for reduction and reverse drive engagement respectively with a countershaft wheel and an idler. The gear may be used on a motor road vehicle and no main-clutch is necessary.

Title: Improvements in astronomical calculating apparatus
IPC: G06G1/14
Filed: 1927-07-25
Abstract: 295,122. Ploner, F. July 25, 1927. Calculating - apparatus for astronomy and astrology. Relates to apparatus for casting horoscopes, the device being also applicable for ascertaining the times of rising, setting, and other diurnal positions of the sun, moon, and planets. The apparatus consists of two charts one of which is transparent, A showing the positions of the sun, moon and planets, and B the positions of the "cusps" of the "houses" (the Ecliptic being divided into twelve equal " houses " in each of which the "cusp" is the beginning point). The horoscope is conveniently read for any day and the succeeding days by means of a transparent graduated scale or " aspectreticle " C.. The charts A and B are set out according to co-ordinate scales H representing sidereal time and E the celestial longitude, the, signs of the zodiac having 30‹ each. The sidereal time of mean noon at Greenwich gives points on the scale H from which parallels d are: drawn for each day. For these time lines and the scale E the sun, moon, and planet positions are plotted, the moon path being divided every three hours for reading mean time. The cusps of the twelve houses are plotted on the chart B similarly. A scale h equal to H is provided on chart A to read against the point o on chart B. A horoscope, is found by setting the mark o against the time of day of scale h, local time; then along the line d for the given day a point of the moon-line m is found from which a distance is travelled along the graduated moonline equal to the Greenwich time equivalent to the given day-time. Through the point so found the vertical line R of the recticle C is placed, the intersection thereof and the sun, moon, planet, and house cusp lines giving the horoscope. Using the symmetry of the charted curves a more compact form of charts is made as shown at Figs. 3 and 4. For portable forms the chart B and reticle C are made in the form of transparent bands working round a stiff card base carrying the chart B.
