Title: Improvements in or relating to gas turbine systems
Inventor: PUNCOCHAR JAROSLAV
IPC: F02C6/00
Filed: 1962-07-24
Abstract: The invention relates to a gas turbine system in which combustible gas is produced from solid fuel and with wet dust removal as set forth in the parent Specification.  According to that invention, a gas turbine plant uses working fluid derived from solid fuel, the working fluid being produced by first producing combustible gas from the solid fuel, the gas then being burned <PICT:0952814/C3/1> with air under pressure in a combustion chamber, the gas producer being supplied with a gasefying medium which is obtained by combustion of part of the produced gas with air under pressure in an auxiliary combustion chamber, the gas producer being operated at a relatively low temperature (about 100 DEG  C.).  In accordance with the present invention, the turbine working fluid is reheated at least once during its expansion by combustion of producer gas, there being utilized for the production of the producer gas part of the working fluid tapped from the preceding turbine stage and introduced into the gas producer.  In the embodiment shown, air is compressed in two compressor stages K1 and K2 and introduced into the main combustion chamber SK1 together with gas from the producer G1, the resulting combustion products passing to the turbine T1 which drives the compressor K2, then after being reheated in the reheat combustion chamber SK2, to the second-stage turbine T2 which drives the compressor K1.  The gas producer G1 operates as disclosed in the parent Specification, a portion of air from the compressor K2 being further compressed in the compressor TD1 and admitted into the auxiliary combustion chamber PSK together with producer gas delivered by the producer itself and compressed in the compressor TD2.  The resulting combustion gases pass into the gas producer.  The combustible gas from the producer is cleaned in a scrubber C1 and then passes into an accumulator S1 from which the main portion of the gas passes to the main combustion chamber SK1 and the remaining portion passes to the compressor TD2 and so to the auxiliary combustion chamber PSK.  In the case of the gas producer G2, a portion of the exhaust gas from the first-stage turbine T1 is re-compressed in the compressor TD3 and then admitted into the producer, the resulting combustible gas being cleaned in the scrubber C2 and then passed into the reheat combustion chamber SK2.

Filed: 1954-10-08
Abstract: 774,216. Window operating mechanism. PRODUCTIVE INVENTIONS, Inc. Oct. 8, 1954, No. 29124/54. Class 20(3) [Also in Group XXIV]  In a screw and nut mechanism for a power-operated window-raising device for a vehicle, each of a pair of motor-driven screws 1, Fig. 1, is engaged by a "nut" 3  comprising three thread-engaging rollers rotatable about axes parallel to the screw in a carrier surrounding the screw, the " nut" being connected to the window 5 through a rubber block 38. A bearing for the upper end of the screw is supported on a rubber block 10. The three rollers 16, Fig. 4, are mounted in pockets provided by offset formations in a pair of nested retainer members 13, 14: Each roller has a convex periphery engaging the screw thread, and the three rollers are preferably equally spaced axially and circumferentially and preferably' co-operate with a double thread on the screw-two in one thread and one in the other. The ends 32 of a looped and bent fitting 33, Fig. 1, are journalled in aligned apertures in the members 13, 14 and the loop is held by a pin 40 in a slot in the rubber block 38 which is pivoted to a yoke 35 secured to the window. The base of the slot in the rubber block preferably has an inclined portion, Fig. 3 (not shown), which is compressed by the fitting 33 so that its resilience maintains the parts in position. In a modification, Figs. 11, 12, each roller consists of two convex surfaces having elliptical cross-sections so as to have point contact with the screw thread inward from the crest thereof. The rollers are carried in nested retainer members supported between the sides 48 of a hanger which is connected to the depending arms of a bracket 51 supporting the window frame. Resilient means 54 is interposed between the bracket and the hanger. Offset portions 56 on the hanger limit the pivotal movement between the hanger and the bracket, while inturned portions 57 control the movement between the roller assembly and the hanger. The arrangement is such that the rollers crank on the screw to hold the window in its adjusted position. Each roller may be made in one unit or by an assembly of parts and may be rigid with or rotatable on its axle. It is pointed out that, amongst other advantages, multiplecontact rollers provide grooves between their convex surfaces which prevent any "ironing out of the crest of the screw thread into a sharp edge. In a modification a screw is engaged by two axiallyspaced roller assemblies, each having three rollers, the rollers in one assembly being angularly located midway between those of the other assembly.

Title: Improvements in or relating to the treatment of peat
IPC: C10F7/00
Filed: 1951-12-12
Abstract: Wet peat from the bog is subjected to a treatment in an autoclave under pressure at temperatures between 100 DEG C. and 180 DEG C. until a peat of high cohesion is formed, whereupon the prepared peat is pressed into blanks which are subjected to a heat treatment of about 100 DEG C. until the material has become completely solidified. The peat from the upper layers of a bog, is pressed, e.g. between squeeze rolls, to remove about half of the water, and is then heated in an autoclave to 170-180 DEG C. during which time the pressure rises to 7-8 atmosphere above normal.  The acid normally present in the peat is sufficient to ensure the conversion of the peat.  The prepared peat is again heated to about 100 DEG C. to give 62 per cent. peat and 38 per cent, water and is then placed into the open air for about 12 hours to remove all moisture.  By treating the peat, after preliminary pressure, to a temperature of about 120 DEG C. the fibrous structure of the peat is retained and the product is suitable for making fuel briquettes, building boards &c.  If the peat is prepared at about 150 DEG C., the water squeezed out and the product dried, a powder is obtained which can be worked up in powder form. The product is preferably given an oxidization treatment. e.g. by oxygen, hydrogen peroxide, chloride of lime, sodium hypochlorite &c., when it is used for moulding purposes.  Glycerine and various synthetic resins may also be added.  If the wet peat is treated with an alkali, e.g. soda, or lime, the product is of uniform colour, is harder, and has a better finished surface than when it is prepared with an acid.  The malleability, the tensile strength, and the fire resistivity of the product are also increased.  The peat may be treated in a neutral state and an alkali may be added after a neutral, or after, an acid processing.  The water soluble components of the peat can be removed by distillation in a Soxhlet apparatus, care being taken to ensure that the mass does not become dry; or in the case of finished moulded bodies, by heating them in an autoclave with a small amount of water.  Hot waste waters can be used for heating the autoclaves which may, if desired, be replaced by centrifuges.
