Abstract: 787,673. Vaporizers; cycles; materials special used for actuating. ESSO RESEARCH & ENGINEERING CO. April 12, 1956 [May 13, 1955], No. 13880/55. Addition to 714,672. Classes 7(2) and 7(3) In a diesel engine liquid fuel is supplied to a vaporizer 4 by a jet 1, at least a part of the fuel boiling below 200‹C. is vaporized, means being provided for admitting vapours from the vaporizer with the, induction air to the cylinder of the diesel engine, and an injector pump is fed with unvaporized fuel. The pump may draw fuel through the passage 5. The vaporized fuel passes through the exit 3 into the air stream. The vaporizer may incorporate a ball valve actuated by a float or a weir. Heat may be supplied by the exhaust gases or the cooling water or by electric power more heat may be supplied to the vaporizer as the engine throttle is opened. A simple valve or rheostat arrangement may be used for this purpose. The supply of fuel is related to the throttle opening. The fuel used comprises a blend of conventional diesel fuel with a gasoline or kerosine fraction. The fuel blend may comprise a primary fuel boiling between 150 and 450‹C., and a secondary fuel boiling between 50 and 360‹C. A particularly suitable fuel blend comprises from 70 to 90 per cent, preferably 75 to 85 per cent of primary fuel and from 10 to 30, preferably 15 to 25, per cent of secondary fuel. In Fig. 2 the vaporizer temperature should not be allowed to rise above that required to vaporize fuel boiling below 200‹C. and preferably below 150‹C. A diesel engine is defined as a four stroke compression ignition engine in which the air entering the cylinder during the induction stroke does not exceed atmospheric pressure.

Abstract: 834,971. Ventilating. STEWART-WARNER CORPORATION. May 2, 1958, No. 14143/58. Class 137 [Also in Groups XI and XXVII] A vehicle heating system comprises a burner, a heat exchanger having a combustion chamber and an exhaust, a nozzle delivering fuel to the burner from a pump through a valve, a spark ignition, a blower delivering air to the burner, and an electric control system to open the fuel valve and operate the ignition when heat is required and to close the valve and stop the ignition when heat is not required and also to operate the blower independently of the operation of valve and ignition. As shown, fuel is supplied from a pump 62 driven by a motor 66 through a valve 64 to a nozzle 36 in a perforated burner cone 32, a blower 40 also driven by the motor 66 supplying air for combustion through the perforations. A fan 24 supplies air over a combustion chamber 30, having an exhaust 34, to a plenum 12 from which the air is distributed to various positions within, for example, a motor car. A temperature sensitive device 70 in the plenum when in the closed position operates relays to start the motor 66, open the valve 64 and energize a transformer to supply current to a spark gap 50 in the burner cone near the nozzle; when the required temperature is attained in the plenum the valve 64 is closed, the motor 66 remaining in operation, and the spark stopped. The fan 24 may be used to drive air over the combustion chamber or the ram effect of motion may produce the flow. A further fan 18 may be provided for defrosting.

Patent GB-144544-A (GB)
Abstract: 144,544. Haddan, A. J. H., (National Cash Register Co.). March 7, 1919 Type-wheel action.-In cash registers or other machines wherein item values are printed, by type-carriers adjusted by differentially-moved racks, the printing of unnecessary ciphers is prevented by automatically moving the racks one step beyond zero position. As shown applied to the machine described in Specification 144,373, the rack-bars 305 appertaining to all denominations except units engage the gear wheels 301 connected with the amount type-wheels and are differentially actuated by segmental pinions 310. A floating pawl 374 for each bar is pivoted on a suspended rod 375 embraced by a bifurcated cam-moved lever 389 and has a nose 372 for co-operation with a notch 371 in the bar. Each pawl has a projecting portion 385 which engages behind the end 386 of the next higher pawl, and a spring 370 connects an arm 378 of the pawl with a three-armed rocking member 379. At the commencement of operation of the machine, the lever 389 moves clockwise to the position shown in Fig. 2, the noses 372 all being raised owing to contact between the ends 386 and the shaft 377. After the rack bars have been actuated and before the alining pawls 369 engage the gear wheels 301, the lever 389 returns to the normal position shown in Fig. 4. If a rack bar has been actuated, its notch 371 has passed beyond the reach of the pawl nose 372, but if not, and provided no higher rack-bar has been moved, the pawl engages the notch and the rack-bar is dragged one step to the left; the corresponding type wheel will consequently print nothing or an asterisk or other sign instead of zero. In the event, however, of a higher rack-bar having been actuated, the pawl of this higher bar being unable to descend sufficiently to engage its notch 371 will prevent all lower pawls from engaging their notches owing to the projecting portions 385, and consequently the corresponding rack-bars will remain in their zero position and noughts will be printed. The actuating pinions 310 are furnished with a flat portion 388 to allow the retrograde step of the rack-bar, and when this occurs a hook 395 on the bar engage a tooth 394 on the pinion so as to lock it. At the next operation of the machine, any pawl previously engaging its notch is raised and the spring 370 acting through the rocking member 379 and a projection 383 moves the rackbar to normal zero position.
