Filed: 1920-12-09
Abstract: 175,473. Frith, W. J. Dec. 9, 1920. Countersunk tips.-A heel-protector, designed to be applied without the use of screws, nails, &c. comprises a metal housing A, shaped to fit within a. recess F cut in the heel, and secured therein by screws. The recess F is cut with a narrow neck-lilie portion and has bevelled edges, as shown. A weaning-pad B of similar shape and also having bevelled edges G is pushed into and held by the housing A, a central slit H being provided, in the case of a rubber pad, to facilitate insertion and removal. When a metal pad is used, it is made in two parts hinged together by a strip of rubber or thin metal. In the modification shown in Fig. 3, the recess F and the housing A are enlarged to receive a, reversible pad B. A number of slightly modified forms of metal housing are also described.

Title: An improved apparatus for applying colour to tiles and like articles
IPC: B28B11/00
Filed: 1933-12-18
Abstract: <PICT:0432193/III/1> In apparatus for applying colour to tiles and the like, the latter are carried along on a horizontal band or conveyer beneath one or more colour containers having a plurality of colour outlet nozzles from which small quantities of colour are deposited on the surface of the tiles, the colour, before it sets being subjected to an air or like blast from a plurality of nozzles so as to spread the colour, or to mix different colours, on the surface of the tiles.  The operation of the colour outlets and of the air blast nozzles is derived from the conveyer so that the deposition of the colour and the succeeding air blast are synchronized with the movement of the tiles.  The tiles may be passed beneath a further container from which glaze is deposited on the tile after the colour has been subjected to the air blast.  The valve controlling the colour outlets comprises a plate 14, sliding in a member 12 attached to the lower part of the colour container 10, and having holes which are moved into and out of alignment with the colour outlets 11.  The plate 14 is displaced against the action of a return spring 25 by a tappet 18 and a cam mounted on a member 17.  The displacement of the plate 14 can be varied by means of a wedge-shaped member 20, carried by a link 21 depending from a lever 22, and interposed between the tappet 18 and a boss 19 on the plate 14.  The lever 22 may be set in any desired position by means of a locknut 24.  The cam actuating the colour outlets and the valve, which may be of piston type, controlling the air supply to nozzles 16<a> from a chamber 12<a> in the member 12, are both operated from the tile conveyer through the medium of an endless chain and a pair of sprocket wheels. Specification 391,208 is referred to.

[Also in Division G2] The invention relates to apparatus for measuring or monitoring the refractive index of a fluid and comprises a light transmitting rod 80 for at least partial immersion in a fluid 27 under test, a light source 96, an optical system for introducing light into one end of the rod 80, and a light sensing device 186 to deliver a variable signal dependant on the amount of such light that is transmitted through the probe by internal reflection, the amount of light lost from the rod 80 depending on the relative refractive indices of the rod material and the fluid in which it is immersed, wherein the end of the rod at which the light enters has a bevel face 90 that is at some predetermined angle other than a right angle to the longitudinal axis of the rod, the optical system being arranged so that light therefrom impinges on this face. The optical system in the embodiment shown consists of lenses 120, 122 adjustably mounted so that light from the source 96 may be focused in an elliptical area on the bevel face 90 and light that is internally reflected down the rod is reflected back up the rod by a reflecting surface 86 to the light sensing device 186 which may be a solar cell. Light from the source 96 also impinges on a reference solar cell (Fig. 7 not shown) disposed behind a filter 170 of glass or other transparent material and having light absorbing characteristics such that the quantity of light lost passing through the filter 170 is the same as that which is lost in the rod 80 due to absorption. The output signals from the cell 186 and the reference cell are fed to the circuit shown in Fig. 8 by conductors 210, 212 and 180, 182 respectively. The signals from the cell 186 are fed direct to one input terminal of the amplifier 224 and those from the reference cell are fed through a potentiometer 218 and its wiper 220 to the other input terminal of the amplifier 224. The amplifier output is applied to a balancing motor 226 which moves the wiper 220 until the net e.m.f. across the input terminals of the amplifier is zero and also moves a pointer 214 along a scale which may indicate directly the refractive index of the fluid under test. The apparatus may be calibrated in density, specific gravity, &c. if desired.

A gate lock mechanism on the cage of a builders' hoist is adapted to be freed by rotation of a hand lever 7 which, through links 8, 11 and bellcrank levers 9, 12, projects a roller 13 into the plane of ramps located in the hoist shaft, one at each landing. On engagement of the roller with a ramp, further rotation of the hand lever 7 causes a lever 10, pivoted to the lever 9, to rotate a shaft carrying a bevel gear 15 thereby, through a bevel gear 16, a lever 17 and link, pivoting bell-crank levers 5, 6 upwardly to disengage a lock bar 4 from a beak 3 on the sliding gate 2. When the roller 13 is not adjacent a ramp, rotation of the lever 7, the lever 9 rotates about its pivotal connection with the lever 10 which remains in the position shown. Surplus hoisting rope, which may be paid out as the hoist tower is extended, is stored on four spools 21, Fig. 3 (not shown), rotatably mounted on the tower 32.
