Abstract: 325,008. Marks, Sir G. C., (Horn, J. A. L.). Nov. 10, 1928. Sand glasses; timelimit devices. - A device for timing cooking operations or for actuating an electric switch comprises a sand glass device which rocks, after the sand has flowed from one division to another, to actuate a visible or audible signal or to operate a switch. The sand may be replaced by a liquid or by a, weight falling through a liquid. The sand glass 1 is contained in a case 2 the ends of which are extended at 4 to support a threaded rod 5 upon which is a counterweight nut 6. The case is pivoted at 9 to brackets 10 on the base 11 and is adjustable as to its initial position by a screw 15. A frame 14 also pivoted at 9 carries a hammer 13 for the bell 12. When the sand passes to the lower half of the glass 1 the centre of gravity shifts to the left of the axis 9 and the device rocks counterclockwise to move frame 14 which comes back against pin 16 to strike the bell sharply. The timing is adjusted by the nut 6. In modifications (1) the sand is replaced by liquid such as oil, kerosene or diluted spirit of wine, and a cap to the container forms the counterweight, (2) in place of the central narrow orifice, the liquid passes through a small tube to the lower half of the container and is returned to the upper half .through a large tube, (3) a ball falls slowly through liquid to cause the overbalancing, (4) this ball is replaced by a cylindrical weight fitting the cylindrical container closely and having a central passage with a one-way valve, and (5) the weight or ball is adapted when it overbalances the device to cause the latter to open a switch'35, 36, Fig. 11, the device being returned to the set position shown by a disc 37.

IPC: C10B55/02
Filed: 1933-11-28
Abstract: Coal/oil mixtures are destructively distilled and cracked to obtain coke and hydrocarbons of low boiling point by introducing the mixture into the upper end of an inclined rotary retort externally heated from 350 to 550 DEG  C., the volatile products being withdrawn from the upper end while the mixture as it passes down the retort is gradually reduced to coke which is removed at the lower end.  Steam is introduced into the retort to assist cracking by infra-red radiation into the distillate and the amount of material passing through the retort maintained under atmospheric pressure is kept small in comparison with the volume of the retort.  The apparatus used is the same as that described in Specification 393,602. Specifications 426,645, 427,960; and 430,649, [Group XII], are referred to.

Abstract: 179,216. Meurer, N. Nov. 27, 1920. Enamelling, vitreous.-In the enamelling of metal, ceramic, or other heat-resisting articles by spraying enamels, glass, or mixture rich in quartz on to the articles by means of gases under pressure, the coating-material being forced through a powerful flame, the heated surface of the article is heated by the spraying-jet to the fusing-temperature of the coating-material, and the flame that effects the melting and heating has a reducing action to prevent oxidation. The coating- material is contained in a vessel 1 connected by a hollow handle 2 to the nozzle body 3. Fuel under pressure is supplied through a nipple 4. and compressed oxygen or air through a second nipple 4a. The fuel passes through a cock 11 into a chamber 5. The oxygen &c. passes through an adjustable valve 9 and on through a duct 7, and mixes with the fuel at the valve 16, 17. A supply of oxygen also passes through a cock 14, up through the handle 2, and into the chamber 1 through openings 29 in the base. The coating- material, agitated by the oxygen &c., passes on through an adjustable central valve 31 and down through a duct 32 into the nozzle. The fuel and oxygen &c. issuing from the valve 16, 17 carry the coating material along, accelerating its motion, on through the removable nozzle 21. A supply of fuel is also passed into a second nozzle 23 surrounding the nozzle 21. The valve 9 and duct 7 are mounted in a screwed-in insertion piece 6. The parts 19, 20 forming the duct 18 leading to the nozzle 21 are readily removable. The supply of oxygen &c. is regulated to give a reducing flame.

[Class 9 (ii)] [Also in Group XXXIII] An aircraft fitted with booster rockets for assisted take-off is provided with automatic trimming or stabilizing means comprising two vanes or vaned members, one disposed in the rocket jet stream and the other exposed to the external air stream, the second member being arranged so that movement thereof will incline the first to the direction of the jet'stream to produce a compensating effect. Fig. 1 shows an arrangement consisting of two vanes a, g, mounted on parallel geared shafts d, b, the vane a being mounted to the rear of the rocket c and the vane g in the external air stream. In flight changes of trim cause movement of the vane g which is communicated to the vane a to vary the angle between the latter and the rocket jet stream to produce a restoring moment. In the arrangement according to Fig. 5, the vanes a, g are mounted on a common shaft j, the centre of pressure of the vane g being forward of the shaft. A ratchet k and detent m serve to hold the vanes stationary after a maximum speed setting is reached. In a modification, Figs. 7 and 8 (not shown), the vane g is L-shaped, the lower limb projecting forwardly for pivotal balance and the other limb extending upwardly. Fig. 9 shows a further embodiment for use in quick launching, the acceleration period being about 10 to 20 seconds. The vane a is continuously rotated by a windmill g disposed in the airstream and which is automatically locked at the end of the launching period; the whole device may be jettisoned with the rocket case. The vane a may be in the form of a tube, the jet stream from the rocket impinging against its inner wall.
