Title: Device for the compression of additional air for supercharging combustion engines
IPC: F02B1/00
Filed: 1972-05-18
Abstract: 1358627 Charging I C engine; rotary valves USTAV PRO VYZKUM MOTOROVYCH VOZIDEL 18 May 1972 [2 July 1971] 23475/72 Heading F1B An I.C. engine comprises at least four cylinders I .. IV, Fig. 2 each having a differential piston 6, Fig. 1, and a rotary valve part of a cam-shaft 14 wherein each cylinder, e.g. I, when its piston is at b. d.c. after its suction stroke supercharges itself with additional air from annular space 7 while another piston IV also at b.d.c. charges the annular spaces 7 of two other cylinders II, III (whose pistons are at t.d.c. and whose annular spaces have been filled with air sucked from the crank-case or atmosphere) with air sucked in and compressed during its preceding rising and descending movements. Air is sucked through hole 8, groove 17 and duct 9 2  into space 7 when the piston rises and is compressed when the piston descends to be forced through duct 10 and cavity 15 to the annular spaces of cylinders II and III (at t. d.c.). When the piston in cylinder II descends the compressed additional air is forced via ducts 9 2 , 9 1 , and groove 18 into the combustion space of cylinder II. The duct 9 1  may be replaced by tangential ducts. Additional air may also be admitted to the combustion chamber via duct 20. The air compressed in annular spaces 7 may be admitted into the exhaust passage downstream of the exhaust valve.

Title: Improvements in and relating to boring and other machine tool spindles
IPC: B23B31/26
Filed: 1958-07-23
Abstract: 839,951. Washing-tool spindles. VERWALTUNGSGESELLSCHAFT DER WERK ZEUGMASCHINENFABRIK OERLIKON. July 23, 1958 [July 27, 1957], No. 23639/58. Class 83 (3). A device for attaching tools with different shank connections to boring and other machine-tool spindles, comprises a rod 9 keyed by a pin 19, Fig. 1, to rotate with a coaxial machine spindle 3. The rod 9 is movable axially, and when moved to the right, a tool 22 having a long cone is removed from the spindle. A second short-coned tool 31, Fig. 2, may then be fitted by using an extension 23, this tool being pulled into a chuck 34 by spring 13 previously compressed on ejection of the first tool. In operation, oil enters the bore 8 under pressure through shaft 6, Fig. 1, and then through a bore in rod 9 and through transverse holes between pistons 10 mounted on rod 9, and bushes 18 located in the spindle, The rod is then moved to the right, compressing springs 13, 17 and ejecting the first tool 22. In this position, an extension 23, Fig. 2, having a bayonet joint connection with rod 9 is forced by a spring 25 and a pin 26 against a shoulder 27, and secured against rotation by a key 28. A second tool such as a milling cutter can then be secured to the extension. When the oil pressure is released and the rod 9 moves to the left, the short cone 31 of the cutter engages with the corresponding hollow cone in the spindle, the face 32 being pulled against the face of the spindle, and the cutter is held against rotation relative to the spindle by projections engaging recess 34. The feed of the spindle in the housing 1 is by rack and pinion 4, 5, and the spindle drive is from gearing (not shown) through shaft 6 and coupling 7.

Title: Slasher beam changer and winding mechanism
Inventor: QUINN EVAN VICTOR
IPC: D02H3/00
Filed: 1955-08-17
Abstract: 812,280. Beaming yarns. UNISTEL TEXTILE MACHINE CORPORATION. Aug. 17, 1955, No. 23675/55. Class 142(1) A beam changing and winding device for yarns delivered from a slasher comprises two or more beams which can be quickly interchanged when one beam is full, and means for cutting the yarns and attaching them to an empty beam without stopping the delivery of the yarns from the slasher or altering the yarn tension. The beams are rotated independently through clutches by an electric motor. Beams 28, 30 are mounted on a frame which pivots about a shaft 14 to interchange the beams. Yarns 52 from the slasher pass round rolls 48, 50, round a tension roll 54, over the roll 30 and a guide roll 96 and are wound on the roll 28. When roll 28 is full, a clamp 80 is lowered by electrical means 82 on to a lower clamp 78 to hold the yarns and a pneumatic cylinder 68 lowers an electrically heated cutter on to the yarns. Alternatively, the cutter may comprise two serrated blades one sliding on the other. A solenoid operated shoe 102, which is moved manually by a lever 112 to a position adjacent its operative position, presses the cut yarns on to an adhesive backing on the spindle of beam 30 while the roll 54 maintains the yarn tension. The frame is then pivoted, by an electric motor, about its shaft 14 to replace the beam 28 by the beam 30.

Title: Process and apparatus for the purification of gas obtained from coal, lignite, and the like
IPC: C10K1/12
Filed: 1937-08-31
Abstract: In the purification of coal, lignite, coke oven &c. gas, from hydrogen sulphide, carbon bisulphide, cyanogen compounds and carbon dioxide by washing with caustic alkali solution, the foul liquor consisting mainly of unchanged caustic alkali, with the alkali sulphide, thiocyanate and carbonate, is regenerated by means of calcium hydroxide in the presence of alkali carbonate added to the liquor in a quantity corresponding to or greater than the equivalent of alkali fixed by the acids in the gas other than carbon dioxide. The presence of carbonate during the regeneration inhibits the formation of soluble calcium salts, calcium carbonate being precipitated.  When sodium compounds are used, the regenerated liquor therefore consists of NaOH, Na2CO3, Na2S and NaCNS (the ammonia in the gas having been previously removed or not) and this liquor is recirculated to the primary washing tower.  Bye-products may be recovered from the regenerated liquor.  Thus by controlled evaporation crystals of Na2S may be obtained and a concentrated solution of NaCNS.  The latter liquor or the liquor before crystallizing out Na2S may be treated with p  zinc sulphate solution to give white zinc sulphide containing traces of zinc carbonate and hydroxide and a liquor comprising sodium sulphate and thiocyanate. The latter liquor may be concentrated to give Na2SO4, 10H2O crystals; the residual liquor rich in NaCNS may be dried and calcined to give anhydrous Na2SO4.  This residual liquor, however, may be treated with CuSO4 and SO2 to give a white precipitate of cuprous thiocyanate and the final liquor neutralized with Na2CO3 before crystallizing out Na2SO4, 10H2O therefrom.

Title: Improvements in or relating to centrifugal spinning or twisting machines
Inventor: HAMMINK JAN FREDERIK
IPC: D01H1/08
Filed: 1951-10-12
Abstract: 767,710. Centrifugal spinning and twisting apparatus. NAAMLOOZE VENNOOTSCHAP SAJETFABRIEKEN P. CLOS. & LEEMBRUGGEN. Oct. 12, 1951, No. 23776/51. Class 120 (2). A centrifugal spinning or twisting machine in which the thread is wound on to a spool after being deposited in a pot includes mechanism for providing a length of twisted thread for use when re-starting spinning, characterized by a delivery roller shaft being provided with clutch mechanism connected to the doffing means. To initiate unwinding of the thread from the inside of the pot 4 on to the spool 11, the spool 11 is raised by means of a handwheel 15 until it has risen about a half-way, whereupon the delivery rollers are stopped, after which the spool 11 continues upwardly into the pot. A thread-catching member 31 contacts the thread to start the unwinding. The spool 11 is then lowered by rotation of the handwheel 15, which is connected through a worm 17, sprocket wheel 23, chain 24, sprocket wheel 25 to pawl and ratchet mechanism 28, 29. Wheel 29 is fixed to the bottom delivery roller shaft and is only rotated by the pawl 28 when the handwheel 15 is rotated to lower the spool 11, so that thread is delivered as the spool 11 descends. For doffing of the spool 11, the spool is tilted forwards about a shaft 14 and the thread extending into the pot 4 chafes against the bottom edge of the pot so that it is broken and spinning is re-started.
