Title: Improvements in or relating to fuel or fuel mixture vaporizers for internal combustion engines
IPC: F02M21/10
Filed: 1932-10-26
Abstract: 405,760. Vaporizers. GODWARD, E. R., 397, Ellis Road, Invercargill, New Zealand. Oct. 26, 1932, No. 29945. [Class 7 (iii).] Exhaust gases entering a casing 5 at 11 flow around an internal wall 7, of inverted cone shape and provided with vertically spaced ribs 13, to an outlet 12. Combustible mixture passes through a lower opening 8 in the inverted cone 7 and up winding and rising conical passages 15, inside the cone, formed by vertical walls 14 which are closed at their upper ends by an inverted cone member 17 having at its lower end 18, opposite the inlet 8, a projection 19 adapted to guide the mixture into the passages 14. A ring 21 resting on a ledge 9 in the casing 5 closes the space between the inverted cone 7 and the inner cone 17 leaving a passage 22 communicating through indentations 23 in the top of the cone 17 with the inside thereof, the mixture from the spiral passages 15 thus passing to the inside of the cone 17 and being guided down its surface by a cone 25. The mixture is guided upwards into this cone 25 by a projection 28 on the cone member 17 and, directed by a coned cover 10, which closes the casing 5, passes to the induction manifold through an outlet 30. In the passages 15, the outer walls and the surface of the cone 7 are heated and vaporize the wet fuel particles in the mixture when they are thrown thereagainst by centrifugal force, any particles, which are not vaporized by the hottest parts thereof, running down the heated grooves between the walls 14 and the cone 7 and eventually being returned to the passages by the inrush of mixture through the opening 8. The air and the properly atomized particles keep close to the inner cone 17 and the resulting mixture passing down the inside of this cone keeps it comparatively cool,

Abstract: 1499091 Gas-fired heater E L M LEBLANC 19 July 1976 [28 July 1975 3 Oct 1975 4 Feb 1976] 29960/76 Heading F4T Heating, apparatus comprises a gas burner 11 and a waste gas duct with a forced flow/device 4, the duct having valve 1 to admit air downstream, of the burner, and a heat-sensitive valve control device 9 arranged to open and close the valve 1 in response to the heat output of the burner to adjust its output to an optimum value. In operation, air passes from a duct 5 to the burner 11 and when the latter heats a bimetallic strip 9, valve 1 is opened by a link 17, Fig. 2, so that some of the air instead of passing to the burner, is mixed-with burnt gases at 6 and, is evacuated by fan 4. The extent to which the valve opens, and therefore the amount of air passed straight to be mixed with the waste gases, is determined by the temperature reached by the burner, and the amount of useful heat generated per unit of fuel used is kept constant. The element 9 may be replaced by a thermostat bulb arranged below the burner, Fig. 3 (not shown), or two bimetallic elements (12) (18), Fig. 5 (not shown), or two bulbs (7) (20) Fig. 11 (not shown), may be used. A bimetallic element (10) Fig. 8 (not shown), is used to close valve 1 when cold. Fig. 14 shows a heat sensitive device 8 which controls valve 1 when the burner flame is small against a spring- urged diaphragm 25 which is acted upon by gas pressure supplied from the burner through a conduit 28. The membrane may be subjected to differential pressure of the waste gas on each side of a diaphragm (36) Fig. 15 (not shown). In a modification, the gas is supplied to the burner by valve 50, Fig. 17, having two closures 45, 46, actuated by solenoids 44, 41, and the air supply through valve 1 is controlled as a function of the setting of valve 50, and by an electromagnet 51.

[Class 60] In a machine for grinding helical gearwheel teeth of the type in which the work-piece is given a combined sliding and rotational movement while being traversed in contact with a rotary grinding wheel so that two adjacent tooth faces are ground simultaneously, a work holder fitted with indexing mechanism is rotated by the engagement with a pinion on the holder of two pinions operated by two relatively adjustable racks which are displaced by engaging inclined abutments. In the apparatus shown, the spindle d supporting the work-piece is carried by two coaxial spindles k, l which are connected by the indexing mechanism and rotate in a headstock c mounted on the machine slide b. The spindles k, l are rotated by a pinion m on the spindle k engaging pinions n, o on shafts p, q which carry pinions r, s engaging two racks t, u on a bar w carrying rollers z engaging inclined abutment bars 2. The distance between the racks t, u on the bar w may be adjusted by nuts x to eliminate back lash. The bars 2 are mounted on a base 3 which is rotatably adjustable in a support 4 secured to the machine bed a. The bar w is supported laterally by rollers 6 engaging guides 7 secured to the headstock. The indexing mechanism comprises a plate 10 formed with spaced notches 11 corresponding in number to the teeth to be formed on the workpiece and having a projection 9 engaged by adjustable clamping screws 12 on a plate 8 fixed to the spindle l. A plate 13 fixed to the spindle k carries a pivoted pawl 15 which is normally held in one of the notches 11 by a projecting pin 24 on the pawl engaging a slide 17 attached to the plate 13 by strong springs 18. Towards the end of a reciprocation of the work-piece the slide 17 is lifted from the pin 24 by a roller 19 engaging a cam 22 formed on a ring 20 adjustably clamped to the headstock, the pawl being then only subjected to the pressure of a light spring 29. The pawl is next lifted by the engagement of a pivoted striker 25 on the pin 24 with one of two projections 26 on the cam 22, the striker 25 being prevented from swinging in one direction by a stop 27. The spindle l is then held stationary by a continuously acting brake 32 while the spindle k continues to rotate until at the end of the movement of the slide b the pawl engages with next notch in the indexing plate 10. To prevent pawl wear it is fitted with a roller 30. On the return movement the striker 25 passes idly over the projection 26 and, when the roller 19 disengages from the cam 22, the slide 17 returns under the pressure of the springs 18 When the teeth to be formed on the work-piece are of an opposite inclination, the inclination of the abutments 2 on the support 4 is reversed, the stop 27 is moved to the other side of the striker 25, and the cam 22 is adjusted to bring the second projection 26 into position for operating the striker.
