Title: A method and apparatus for producing elements of concrete and similar settable materials
Inventor: SCHNEIDER WOLFGANG
IPC: B28B3/02
Filed: 1970-05-18
Abstract: 1,246,435. Compression moulding of concrete and like settable materials. W. SCHNEIDER, and K. SCHNEIDER. 18 May, 1970 [22 May, 1969; 5 Dec., 1969], No. 23938/70. Heading B5A. A method for producing elements from settable material, especially concrete, comprises filling an upwardly open mould with material, compacting the material with a press ram from above such that surplus material is removed from the mould in discrete amounts during compaction. Apparatus includes a compaction mechanism 30 having cam plates 32 engageable with mould frames 16. The plates 32 contain apertures in which tubes 50 containing pestles 66, are located. The tubes 50 are connected by a spring-biased yoke 56 which is reciprocatable by an eccentric 60 and guide rod 62. In operation, mould frame 16 is excessively filled with material and mechanism 30 is hydraulically moved so that plates 32 contact and compress the moulding. Tubes 50 are moved through plates 32 into the material by the eccentric 60 and material moves into the tubes so that the moulding depth is reduced, then the tubes are drawn back flush with plates 32. The process is repeated till the moulding is of the desired depth. During this procedure frame 16 is vibrated and jarred. At the end of the compression pestles 66 are moved by hydraulic cylinder 46 to remove the material contained in tubes 50 from the tubes. In another embodiment the tube is connected to a compressed air source instead of a pestle, to enable the tube to be cleared and the eccentric is replaced by an hydraulic cylinder. Apparatus for charging the mould and removing the mouldings are also disclosed (Fig. 1, not shown).

Title: Improvements in and relating to fuel oils and the combustion of fuel oils
Inventor: TAYLOR ROBERT PATRICK
IPC: C10L1/10
Filed: 1951-10-15
Abstract: A fuel oil composition, whose combustion products cause no oxidation, incrustation or corrosion of metallic surfaces with which they come into contact, comprises a high ash residual fuel oil and a minor proportion of red phosphorus or a metal- and sulphur-free organic or inorganic compound of phosphorus (other than an oil-soluble organic compound of phosphorus).  The use of pyrophosphoric acid or mixtures of red phosphorus and sulphur in residual fuel oils is disclaimed. The high ash residual fuel oil is defined as a liquid fuel having an ash content of at least 0.005 per cent. by weight, when measured by method I.P. 4/44 of the Institute of Petroleum, and a viscosity of at least 100 seconds Redwood I at 100 DEG C. and consisting of or containing a residual petroleum oil.  The high ash residual fuel oil may contain liquid fuels other than residual petroleum oils, such as distilled or cracked hydrocarbon fuel oils, while the residual petroleum oil may be one which yields, on combustion, an ash containing a major proportion of vanadium and/or sodium compounds. Inorganic phosphorus compounds mentioned are the oxides and oxy acids of phosphorus, such as phosphorus pentoxide, hypophosphorous acid, phosphorous acid, hypophosphoric acid, the phosphoric acids (other than pyrophosphoric acid) and the perphosphoric acids; the metal-free salts of oxy acids of phosphorus, such as the ammonium salts of the oxy acids listed above; and the hydrides and halides of phosphorus, such as di- and tri-hydrogen phosphide, phosphorus tri- or penta-chloride, phosphorus oxychloride and phosphonium chloride. Organic phosphorus compounds mentioned are the lower alkylphosphoric acid, phosphorous acid, di- or tri-alkylphosphine oxides and the organic base salts of the oxy acids listed above.  Preferred phosphorus compounds are ortho- or meta-phosphoric acid, phosphorus acid, di- or triammonium orthophosphate, ammonium phosphite and ammonium pentametaphosphate.  The red phosphorus or phosphorus compound may be added to the high ash residual fuel oil in bulk to form a solution, dispersion or emulsion, or it may be injected, either as such or as a solution, emulsion or suspension in a suitable liquid medium, such as water or an organic liquid, into the fuel oil supply lines.  The injection may be continuous or intermittent, while a convenient way of adding the red phosphorus or phosphorus compound is in the form of a solution, emulsion or dispersion in a proportion of the high ash residual fuel oil which is to be burnt.  In the examples, an aqueous solution of orthophosphoric acid or of triammonium orthophosphate, or red phosphorus, are added to petroleum residual fuel oil.  According to the Provisional Specification, white phosphorus and other allotropic forms of phosphorus, pyrophosphoric acid, and sulphides of phosphorus such as phosphorus pentasulphide, may be employed.

Filed: 1936-09-11
Abstract: 481,519. Airscrews. REISSNER, H., and ARGUSMOTOREN GES. Sept. 11, 1936, No. 24823. Convention date, Sept. 12, 1935. [Class 114] In variable-pitch airscrews automatic adjustment is obtained from a power source constituted by a rotating auxiliary screw coaxial with the propeller and adapted to be clutched to one or other of two oppositely driven mechanisms. The blades 3 of the screw propeller are provided at their roots with worm wheels 4 which are geared to transverse worm wheels 5 and thence through other gears to a main worm wheel 9 which is in permanent mesh with the worm 10 on transverse shaft 11 upon which are freely mounted bevel wheels 12, 13 meshing with a bevel wheel 14 upon a shaft 15 driven by an auxiliary propeller, the blades 18 of which may have some or no pitch. When pitch variation is desired, couplings 23, 24 are moved to engage the desired bevel wheel with the transverse shaft 11. One method of effecting this is by hydraulic pressure on coupling pistons 21, 22, the pressure in the conduits 25 being controlled either by the pilot or if desired by an automatic speed control. Instead of the cylinders acting under oil pressure, electromagnets 38 may be used and the coupling clutches 21b, 22b drawn into position electromagnetically. In order that adjustment may be stopped at any desired maximum position the cross shaft is provided with a screw 40 and a rod 39 which in the maximum position of pitch adjustment contacts with the flange 42 of the coupling 226 and so cuts out the gear. The control may be effected centrifugally by providing a weight 27 under the control of a spring 28 whereby the cross shaft 11a is moved to bring the claw couplings 21a, 22a into engagement with its pinion 12a or 13a. In this case also a stop mechanism is provided, a cam 29 on the root of the blade contacting with a rod 30 and through the pivoted lever 31 acting upon the cross shaft 11a. In a modification, instead of bevel wheels, two opposite handed worms 46, 47 are provided on shaft 48 which rotates with but is free to slide within the shaft 15a of the auxiliary propeller 18. Movement of this shaft axially is effected by controlling solenoids 49, 50, whereby one of the worms 46, 47 is brought into mesh with a worm 45 on the pitch changing gear.
