Title: Improvements in high-pressure steam generators
IPC: F22B35/10
Filed: 1928-02-16
Abstract: 285,445. Geiger, L., and Joerg, J., (Assignees of Soc. Mecum a.r.l.). Feb. 16, 1927, [Convention date]. Liquid fuel supply.-A float l, Fig. 5, in a vessel B in the feed pipe of a boiler is connected to a valve 0 controlling the escape of air from a pipe r connected to the apparatus supplying fuel to the burner. When the feed is stopped, the water level in the vessel B falls and the float opens the valve 0, thus allowing air to escape and lowering the intensity of the burner flame. In a modification, the pressure in the air pipe is normally balanced by a water column, and air escapes through the column when the water level falls in the column upon a stoppage of the feed supply.

Abstract: 192,933. Gore, L. S. Feb. 23, 1922. Teaching colours, geometry, and reading.- Apparatus for teaching phonetics, applicable also for teaching colours, angles, and the directions of straight lines and curves and the drawing thereof, comprises two flat discs a<3>, Figs. 3 and 4, arranged face to face and provided with slots or cut-out portions j<5> of straight, curved, or other shape, mounted upon a central pivot k<2> behind two discs or duodecagonal plates a" of smaller diameter, divided into coloured portions l, m and provided with borings d, d<2>, &c. around their peripheries to receive pegs or the like. The faces and backs of the disc a<3> are coloured black and the faces bear an anchor-shaped design, or one or more straight lines and curves, in white or other contrasting colour. The discs a<3> are provided with buttons or knobs w by which they can be turned into different relative positions, the positions of the white lines or curves, or portions thereof, seen through the slits in the upper disc forming mnemonics to the voicing of consonant and like sounds. The colours in the spaces l on the left-hand sides of the plates a<4> are different from each other, but are similar to those in the corresponding spaces m on the righthand sides. The colours form moremonics to the voicing of vowel, diphthong, and like sounds, for example the colour " scarlet " gives the mnemonic to the vowel sound " a " as in " father." The colours are indicated by the insertion of a peg into a circumferential boring, and pegs of different colours inserted at particular positions indicate a modification in the vowel sound; for example, a peg of certain shape or colour inserted at d would give the mnemonic to the French nasal sound to be applied to the vowel sound indicated by the colour within the space d<4>. The colours on the left-hand sides of a plate represent vowels preceding a consonant, and those on the right-hand side the vowels following a consonant. The upper hand of the front plate a<4> is hinged at u to fold upon the lower half as shown in Fig. 4, and bears coloured portions upon its rear side which are thereby exposed and are used in conjunction with colours revealed upon the plate behind it. The apparatus is adapted to be supported upon a blackboard, and in a modification for hand-use the vowel plates a<4> are arranged one on each side of the superposed consonant a<3> and are attached to the handle by which the apparatus is held, the discs a<3> being free to rotate. The vowel plates a<4> may be used alone when teaching vowels or colours, and the consonant disc a<3> may be used without the vowel plates to teach consonantal sounds or the drawing of lines or curves. Specification 177,936 is referred to.
