Patent FI-991107-A (FI)
Inventor: RUOTTU SEPPO
IPC: C10K1/04
Filed: 1999-05-14
Abstract: The invention relates to a process and apparatus for the gasification of a carbonaceous material. According to the process, the carbonaceous material is gasified at an elevated temperature to produce gas, condensable compounds are separated from the gas, and the product gas thus obtained is recovered. According to the invention, in order to separate the condensable compounds the gas obtained from the gasifiers is directed to a dry scrubber (2) operating according to the fluidized bed priciple, wherein it is contacted with the bed material of the fluidized bed, the interior temperature of the dry scrubber being maintained lower than the condensation temperature of the condensable compounds in order to condense these compounds into the bed material. By means of the invention, a substantially tar-free gas can be produced which is suitable for the production of both heat and electricity.

Abstract: 973,344. Semi-conductor bi-stable circuits. RADIO CORPORATION OF AMERICA. Jan. 11, 1961 [Jan. 20, 1960], No. 1135/61. Heading H3T. A bi-stable circuit comprising a negative resistance diode 52 in combination with a transistor 36, has a impedance 48 in series with the collector-emitter path of the transistor, the current through which is maintained substantially constant at one or other of two levels, depending on the state of the diode. In order to reduce hysterisis effects in switching the circuit from one state to another a second diode 50 may be provided connected in series with a constant voltage source 54 to the first diode. The biasing is such that in one stable condition diode 50 is in its low state and diode 52 in its high state, and vice versa in the other stable condition. The diodes may be tunnel diodes, and either an NPN transistor or a PNP transistor may be used, the diodes being appropriately poled. A constant current source may be used in place of the constant voltage source 54, in this case a third diode, which may be either a negative resistance or a positive resistance diode, is connected in parallel with the series connected diodes 50, 52, Fig. 14 (not shown). Fig. 15 shows a logic circuit comprising a number of such individual circuits and employing both PNP and NPN transistors. The bias on the individual circuits may be adjusted to give " AND " or " OR " operation. Specifications 964,897, 964,898 and 973,343 are referred to.

The piston makes one complete stroke during the time that the rotor turns through 90 degrees. Fig. 1 shows the engine at the beginning of the power stroke. After 90 degrees rotation of the rotor 86, the open end of the cylinder begins to communicate with exhaust duct 89 and air compressed between the piston and the closed end of the cylinder passes through transfer ducts 99, 100 to scavenge the cylinder. After a further 90 degrees rotation, the open end of the cylinder communicates with the inlet port 91 and the space between the piston and the closed end of the cylinder has re-filled through check valves 112, 113. During the next 90 degrees of rotation, air is compressed between the piston and the closed end of the cylinder and then transferred to the combustion chamber. Further rotation to the position of Fig. 1 causes compression of the air in the combustion chamber. The rotor runs on bearings on the crank-shaft and is drivingly connected thereto by bevel gears. The crank-pin 111  runs in a block 109 sliding in a transverse slot in the piston. The rotor may be formed with two cylinder bores parallel to each other, the respective crank-pins being displaced 180 degrees.
Patent GB-665292-A (GB)
Title: Improvements in or relating to filters
IPC: B01D39/20
Filed: 1949-01-20
Abstract: A filter element comprises a sintered mass of powdered metal, having such a high degree of porosity that it has insufficient strength to be used by itself, in association with perforated metal sheet, the perforations therein having been reduced in size by rolling.  The rolled perforated metal sheets may form a container for or at least partially surround the sintered mass, or a rolled perforated metal sheet may be located within the body of the sintered mass. Alternatively the sintered mass may be contained in the rolled perforated metal sheet and at the same time other strengthening metal, preferably in sheet form, may be located within the body of the sintered mass.  The strengthening metal may be rolled or unrolled perforated sheets expanded metal or wire gauze or cloth.  The metal powders or the complete article may be given a surface diffusion treatment with chromium or other metals.  In one method a mass of powdered metal is placed in a shaped hollow structure formed from rolled perforated metal sheet and is compacted without substantial distortion of the hollow structure.  The whole is then inserted into a furnace to effect sintering of the powdered metal mass.  In an alternative method powdered metal is put into a hollow supporting structure, a strengthening member of rolled perforated metal sheet is disposed on the surface of the powdered metal and covered with more powdered metal, the mass is compacted without substantial distortion of the strengthening member and the whole is then inserted into a furnace; after sintering the sintered mass is removed from the supporting structure.

Title: Bottle capping machine
IPC: B67B3/02
Filed: 1948-06-12
Abstract: 646,552. Shaping bottle closures. FORD, G. E., and FORDS (FINSBURY), Ltd. June 12, 1948, No. 15900. [Class 100 (ii)] [Also in Group XVII] The cap-making portion of a bottle capping machine (see Group XVII), wherein caps 84 are formed from a strip of metal foil 41 fed therethrough, includes a manually or power-driven shaft 8 movement of which in opposite directions, within limits, operates the cap-forming and strip-feeding mechanisms respectively. The maximum counterclock movement of the shaft 8 causes the die 16 to move as a whole to the left along guides until a ring 116 (slidable against a spring 117 relatively to the rest of the die) pushes the strip against the cylindrical member 100 of the punch 19. The remainder of the die continues to move until the pressure plate 113 (slidable against springs 115 relatively to the rest of the die) presses the strip against the stationary shear ring 106. Shear ring 107 and plate 118 carrying a pressure pad 119 continue to advance ; shear rings 106, 107 coact to cut out the disc from which the cap is to be formed and shear ring 107 now forces back an ejector ring 108 against a spring 111 thereby forming the cap over the exterior periphery of the cylinder 100 whilst the pressure pad 119 coacts with an embossed member 101, removably carried by the cylinder 100, to form the wording &c. on the top. On clockwise movement of the shaft 8 the die and punch are reset and the formed cap is ejected and passes down a shoot 80. Clockwise movement of the shaft 8 to an extent limited by a stop 78 positively moves an arm 62 against a spring 68 clockwise, the arm carrying a spring-pressed one-way latch 63 operatively engaging (in the clockwise direction) one of a number of abutments 61 on the end of a gear wheel 59 thereby rotating the feed rollers 50, 51 for the metal strip. Counterclock movement of shaft 8 permits the spring 68 to swing the arm 62 counterclock, withdraw the latch from driving engagement with one abutment 61 and reengage it with another abutment ready for positively driving it on the next clockwise movement of the shaft. The maximum counterclock movement of arm 62 is less than and is completed before the full counterclock movement of shaft 8 whereby, if this shaft is not given its full stroke counterclock, oscillation of the shaft will feed the strip only, without actuating the die and punch.

Abstract: 574,513. Projectile fuzes. WEST & CO., Ltd., A., and PAVITT, F. J. Feb. 17, 1941, No. 2138. [Class 9 (i)] A delaying mechanism for use on projectiles, such as rockets, which continue to accelerate for a considerable period by self-propulsion, comprises an inertia-member which, under the influence of the acceleration, moves against the action of retarding means to a position in which the delayed operation, such as the arming of the fuze, can take place. In the form shown, the inertia member 2 is mounted on a rocking arm 4 which moves against spring action from a first position in which electric contacts 17 are bridged, to a second position in which other contacts 15 are bridged to effect the desired operation. The arm 4 has a pin-andslot connection with an interrupted toothed wheel 6 geared by a multiplying clock train to a small fly-wheel 3 which serves to retard and time the delay action. The lost motion caused' by the pin-and-slot connection enables the arm 4 to have a free initial movement to effect a quick break of the contacts 17. The arm 4 is retained in the operative position by a detent.
