Title: Method of and apparatus for extracting materials
IPC: C11B1/10
Filed: 1928-08-01
Abstract: 324,681. Fairweather, H. G. C., (Prosco Oils Corporation). Aug. 1, 1928. Extracts, making.-In the continuous countercurrent extraction of fats, oils, &c. the fatty material descends by gravity through the ascending solvent, first passing through a relatively quiescent zone in which the material is freed from air and saturated with solvent, and then through an agitated zone in which extraction is effected. The descending material is stated to filter the ascending solvent. For example cocoa-cake powder or soya bean flakes are fed by rotating arms 20 through a shoot 17 in sufficient quantity to seal the opening, the shoot being extended by a flange 22 to below the level of gasoline or benzol in the jacketed extractor 5 to ensure saturation and prevent escape through the solvent outlet 23. The flakes fall through a quiescent zone BC at least 1ft. deep and then through a zone CD in which they are agitated by rotating arms 26. The extracted material accumulates in a zone DE in which it is compressed by its own weight and is removed continuously by worms 9, 13 to a dryer. The solvent is introduced through inlets 30.

IPC: H03K21/00
Filed: 1960-06-24
Abstract: 921,368. Pulse frequency dividing circuits. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Sept. 22, 1961 [June 24, 1960], No. 22274/60. Class 40 (6). [Also in Group XIX] In a pulse frequency dividing system, pulses are fed to a chain of bi-stable circuits 1B ... NB, gates 1G ... (N-1)G being interposed between each bistable circuit, the gates being opened by pulses from every preceding bi-stable circuit and switches such as 1S . . . NS being provided to control the division ratio. In the system described, the bi-stable circuit XB is reset to the 0 state by the last pulse of each sequence. Pulses can thus be passed from the input terminal 1T via the gate XG to the first valve or transistor bi-stable circuit 1B. Successive pulses operate the succeeding circuits in turn until the 2<SP>N</SP> + 1 pulse restores circuit NB to the 0 state, terminating the output pulse at terminal 2T and resetting circuit XB. Delay lines 1D ... (N - 1)D prevent spurious operation. The Specification describes how the division ratio may be altered from 2 to (2<SP>N</SP> + 1) by closing one or more switches 1S . . . NS.

Title: Calcination of gypsum
IPC: C04B11/036
Filed: 1932-08-13
Abstract: Plaster of Paris is obtained by preheating crushed gypsum, preferably in a zone maintained below 200 DEG  F., and then passing the heated mass through a zone maintained at a temperature substantially higher than the calcining temperature, viz. above 350 DEG  F. and preferably at about 650 DEG  F.  In an apparatus for effecting this process, crushed gypsum is fed from hopper 2 into preheating zone 1, <PICT:0392780/III/1> which is given a successive slow forward and quick backward movement by rotating cam 4 and spring 5.  The zone is heated by electrical means 6.  The material passes in a shallow layer to the calcining zone 9 heated by electrical means 6<1>, 15, and travels therethrough by the agency of cam 4<1> and spring 5<1>.  The temperature of this zone and the rate of passage of the material therethrough are so correlated that over-calcination is avoided, and all of the gypsum is reduced to the hemihydrate stage, the finished material being discharged into a closed cooling pit 11.  The various parts of the apparatus are connected by flexible couplings 7, 8, 12. A steam-outlet valve 13 is provided in chamber 9.

Title: Method for growing single crystals of vanadium dioxide
IPC: C30B17/00
Filed: 1965-05-31
Abstract: A method for growing a single crystal of vanadium dioxide comprises formng a melt of vanadium pentoxide, thermally decomposing a portion of the melt to form vanadium dioxide and precipitating the vanadium dioxide (m.p. 1700 DEG  C.) from the remaining molten vanadium pentoxide (m.p. 690 DEG  C.).  The vanadium dioxide may be grown on to a seed crystal which is gradually withdrawn from the melt.  If the melt is allowed to solidify the single crystal of vanadium dioxide is recovered by dissolving the vanadium pentoxide mass in a dilute aqueous solution of ammonia or sodium carbonate.

Abstract: 898,729. Winding ropes &c. BENTELERWERKE A.G. July 4, 1960, No. 23352/60. Class 120(2) [Also in Group XVI] A device for winding and re-winding webs of fabric or for winding cables and ropes, comprises two rollers 7, 8, each of which may wind or unwind at choice, and is driven by a respective hydraulic swash-plate motor 3, 4, the rate of flow of which is variable. The motors 3, 4 are hydraulically in series and are connected to a hydro-mechanical control which keeps constant the pressure in the conduit 42 connecting the motors 3, 4. This results in keeping constant the speed and tension of the material to be wound. As shown, a swash-plate hydraulic pump 1 is connected by conduits 35, 43, to the motor 3. The outlet from the latter at 42 is connected to the motor 4 and the outlet of the latter is returned by conduit 41 to the inlet of the pump 2. The conduit 42 is connected to one side of a control piston 16 to the other side of which pressure is supplied from a reduction valve 24. In a modification (Fig. 4, not shown) the reduction valve 24 is replaced by a spring adjusted pressure applied to the piston 15. By adjusting the pressure on the right-hand end of the control piston the latter controls pressures applied on opposite faces of a piston 22. The latter is connected by a linkage 18, 19, 20, to mechanism for varying the speed or direction of rotation of the motors 3, 4. The pressure acting via the control piston on the piston 22 is obtained from a pump 17. A valve 21 disposed between the control piston and the piston 22 may be set to reverse the connections to respective sides of the latter.

Abstract: 335,320. Brown, S. C. July 30, 1929. Disinfecting and deodorizing.-A device for disinfecting or deodorizing the air in sanitary closets, telephone boxes &c. and adapted to be mechanically operated comprises, a bellow or piston carrying in the casing thereof a pad or pads impregnated with a liquid or powdered disinfectant, or deodorizer. As shown in Fig. 1, a casing 1 carrying felt pads 6, 7 and attached bv a shackle 5 to a flush chain encloses a loosely fitting disc 10 to one or both sides of which is attached bellows 4 fixed also to the end cover or covers 2, 3. When a shackle 11 attached to the disc 10 is pulled to operate the flush the disc is lowered against a spring 8 and air forced through the pad 6, the rising of the disc on releasing the shackle forcing air through the pad 7. The bellows may be dispensed with if the disc is packed to form a piston. In a modified construction, the casing and disc are rendered unnecessary by connecting the covers 2, 3 by chains which become fully extended when the bellows are opened, and attaching a single bellows to the end covers. In Fig. 3, a bellows 22 carrying a pad 29 is operated by opening a door 21, and it may be arranged for operation when the door is being closed. This construction is also applicable to spring or weight-lifted seats of sanitary closets.
