Abstract: 974,391. Rotary-piston internal combustion engines. KLOCKNER-HUMBOLDT-DEUTZ A.G. May 8, 1962 [May 12, 1961], No. 17627/62. Heading F1F. A rotary-piston I.C. engine comprising a piston having at least three apex edges which is planetarily rotatable within a housing having a multi-arc internal boundary with at least two lobes includes two partial combustion chambers located one behind the other in the rotational direction of the piston at a position where an apex edge approaches a nodal point between two adjacent arcs with one of the partial chambers acting as a pre-combustion chamber in which pre-injection of fuel and consequential pre-ignition thereof takes place. As shown, a three-sided piston 1, Fig. 1, planetarily rotates within a housing 2 having a bi-arcuate epitrochoidal internal boundary 7, a suction port 4, an exhaust port 5 and partial combustion chambers 9, 10 each fitted with a fuel-injection nozzle 12, 13, preferably adjacent the commencement of each chamber so that fuel is injected in the rotational direction 11 of the piston. The partial chamber 9 serves as a pre-combustion chamber into which a small quantity of fuel is pre-injected and then ignites and passes through, e.g., outwardly splayed grooves 21, Fig. 8, in each piston flank to promote efficient burning of the main bulk of the fuel injected through the nozzle 13 into the partial chamber 10. Alternatively the nozzles may be placed at the other ends of the chambers to inject fuel in a direction opposite to the rotational direction 11 or into the middle of the chambers, in which case the fuel splays out in both directions. In another arrangement, each chamber may be fitted with oppositely facing nozzles passing through each of the side walls of the housing. A doubleinjection nozzle, Fig. 6, may be housed in a single casing with a lightly-loaded nozzle feeding the pre-combustion chamber 9 through a duct 19 and a heavier-loaded nozzle feeding the chamber 10 with the bulk of the fuel through a duct 20. In Fig. 7, at each flank of the piston 1, a double-injection nozzle 23 is fitted and fed from a fuel-injection pump 24 which is supplied through ducts 31, 28. To facilitate cold starting an electric heating element 38, Fig. 1, may be fitted.

Filed: 1926-07-16
Abstract: 255,863. I. G. Farbenindustrie Akt.- Ges. July 22, 1925, [Convention date]. Right to Patent relinquished. Drying at particular temperatures.-Gels having small pores are prepared by rapidly drying the jelly at temperatures above 120‹ C. The jelly, such as silica, alumina, iron oxide, or the product obtained by the treatment of alkali silicate with a metal salt, or by the hydrolysis of silicon fluoride or chloride, or a product obtained from a zeolite or slag, may contain a relatively small proportion of water, for instance a silica jelly may contain 50 grams or more of silica per litre. The jelly may be dried partially, purified, and then finally dried. The drying may be effected by direct contact with hot gases such as combustion gases from producer gas or lignite, or hot air heated thereby. Any tar in the gas is not detrimental, and may be removed from the gel by heating to incandescence or by finishing the drying with hot air. For instance, the silica may be dried in a revolving furnace in which the temperature is 150‹ C. at the entrance and 450' C at the exit. In an example, a silica hydrogel is dried in a current of air at 150-200‹ C., preferably 160‹ C., and may be heated finally to a bigher temperature if desired.

Title: Improvements in or relating to liquid piston internal combustion pumps
IPC: F04F1/16
Filed: 1924-07-26
Abstract: 241,635. Christie, S. P. July 26, 1924. Explosion apparatus.-An internal-combustion pump having a gas intake chamber separate from the combustion chamber and in open communication with the lower end of the combustion chamber or with the play pipe is provided with an operative connection between the valve controlling the conduit between the chambers and the exhaust valve for the burnt gases, so that the exhaust valve on closing will close the transfer valve, and on opening will leave the transfer valve free to be opened say by a spring. The combustion chamber 5 and the gas intake chamber 7 are disposed side by side, opening at their lower ends into the play pipe. The combustion chamber is divided by a partition 21, and is provided with air inlet valves 22, an exhaust valve 11 and a valve 12 connecting it with the intake chamber. A check valve 26 is provided beyond the exhaust valve. Gas enters the intake chamber through a valved port 8 with which a measuring device may be combined. The transfer valve 12 is actuated by a rocker 13 adapted to engage a plate 14 on the valve stem and connected through links 16. 17 with the stem of the exhaust valve 11. A timing device comprises a rod 19 acted upon by a spring and by a flow-actuated abutment 20. The reduction of pressure following an explosion and discharge of liquid causes the air inlet valves 22, gas inlet valve 9, and exhaust valve 11, to open, the transfer valve being held closed by the rod 19. On the return flow of liquid, the transfer valve 12 is released, and is opened by a spring, gas is transferred and the burnt products exhaust until the rising of the liquid closes the exhaust valve by impact, and the transfer valve is closed with it. A segmental valve operated through a link by a flow actuated abutment may replace the valve 12. The gas intake chamber may be annular, surrounding the combustion chamber. The transfer valve may be pneumatically or electrically actuated. The apparatus may be used to propel ships or compress air.
