Abstract: 1304807 Centrifugal separator; separating liquid droplets from gas. WORTHINGTON CORP 19 April 1971 [25 Feb 1970] 22380/71 Headings B2P and BIT An apparatus for separating liquid particles suspended in a gas comprises a streamlined centre body 62 coaxially mounted within a conduit 60 to form therewith an annular passageway in which swirl vanes 64 extend between the body and the inner wall of the conduit, the centre body having an open, hollow end facing one end of the conduit, a gas discharge tube 68 extending coaxially from the one end of the conduit to a position adjacent the open end of the centre body, the end of the tube section less than that of the open end of the body, and sealing means 40 closing the one end of the conduit 60 about the gas discharge tube. The conduit 60 is mounted in a tank 10 and extends between an end wall 40 of the tank and a separator 16 which includes a casing 18 secured to the end wall 40. The gasliquid mixture enters the tank 10 through a fitting 12 and is deflected downwardly by a baffle 13 so that heavy particles of liquid are separated and fall to a pool 14 of liquid in the tank bottom. The mixture then enters the casing 18 through a slot 20 and is forced to follow the inner surface of the casing by a baffle 24 which is shaped to form a venturi section 26 and a diffuser section 28. Some liquid particles are centrifuged against the inner surface of the casing 18 and flow by gravity to a drain line 22. The mixture then passes through an agglomerator cartridge 30 which is urged by a spring 50 against the wall of the casing 16 which surrounds an outlet 36 communicating with the conduit 16, a seal being provided at 34. The cartridge 30 consists of sheets of porous filter material made from natural, synthetic plastic or glass fibre held in a perforated cage 32 and causes the liquid particles to coalesce in droplets. Some of the liquid droplets may flow by gravity from the cartridge and down the drain line 22. The gas and the rest of the liquid droplets pass through the outlet 36 into the conduit 60 and turn through the sharp bend of the conduit so that some liquid droplets are thrown against the outer conduit wall by centrifuging action and while adhering to the wall flow by gravity to the lower portions of the conduit. The rest of the mixture is swirled by the vanes 64 thereby separating further liquid particles from the gas by centrifugal action, the separated liquid and gas entering a collector chamber 66 formed by an expanded end of the conduit. The gas is reversed twice (as indicated by the arrows) therebv shedding off more liguid particles and is finally discharged through the tube 68 which may be venturi-shaped or have a constant cross-section. The separated liquid is removed from the chamber 66 through an outlet 72. More than one bend may be included in the conduit 60 between the outlet 36 and the centre body 62. The entrance to the tube 68 may be located closer to or immediately outside the open end of the centre body.

Title: Process for the conversion of organic halogen compounds into their homologous aldehydes
IPC: C07F9/54
Filed: 1956-07-20
Abstract: Organic halogen compounds are converted into their homologous aldehydes by reacting with a tertiary phosphine to form the quaternary phosphonium salt, converting the latter by treatment with a metallic compound which splits off hydrogen halide into the corresponding phosphonium ylides, allowing a formic ester to act on the latter and if necessary hydrolysing the reaction product. As starting compounds there may be used methyl, propyl, isopropyl, hexyl, dodecyl chloride, cyclohexyl chloride, benzyl and diphenyl methyl chloride and the corresponding bromides and iodes, methoxy-, chlor-or carbethoxy-benzyl bromide, allyl bromide, b -cyclogeranyl bromide, ionyl bromide, ethoxy-ethyl bromide, chloracetic acid esters, chloracetonitrile, 1,4-dichlorethane or propylene bromide; as tertiary phosphine there may be used triphenyl phosphine, tri-p-tolyl phosphine, trichlorophenylphosphine, diphenyl - p - tolyl phosphine or naphthyl diphenylphosphines.  As metallic compounds which split off hydrogen halide there may be used methyl, butyl or phenyl lithium, methyl or phenyl magnesium bromide, calcium or sodium acetylide, sodium or potassium amides and alkali or alkaline earth metal alcoholates.  As formic acid esters there may be used methyl, ethyl, benzyl or phenyl formate.  Examples describe the preparation of 21,61,61 - trimethylcyclohexene - (11) - yl - (11)-acetaldehyde, phenyl acetaldehyde, acetaldehyde, butyraldehyde isobutyraldehyde, tridecene aldehyde, hexahydrobenzaldehyde, adipic dialdehyde, formylacetonitrile, 4-[216161-trimethylcyclohexylidene - (11)] - 2 - methylbutene - (2) - al - (1), 4 - chlorophenyl acetaldehyde and 4-methoxyphenyl acetaldehyde.  The process may also be used for the production of b ,g -unsaturated aldehydes from a ,b -unsaturated halogen compounds.

Filed: 1950-09-14
Abstract: 711,213. Variable-speed gearing; clutches. KREIS, F., and S.I.B.A. SOC. ITALIANA BREVETTI AUTOMOBILISTICI AR.L. Sept. 14, 1950 [Dec. 6, 1949], No. 22617/50. Class 80 (2) A partially automatic variable speed gear for a vehicle providing five forward speeds plus reverse, comprises a three-position manual control of three ball clutches and three automaticallyengaging centrifugal clutches A, B, C, the clutches B, C having additional centrifugal weights arranged so that the driver may hasten the automatic engagement by temporarily releasing the throttle. In first gear, the engine is connected through clutch A to a gear 1 which drives a countershaft 4 through gear 2 and freewheel 3. A gear 5 is connected to the countershaft 4 by a ball-clutch 6 and drives the output shaft 15 through gear 11 and freewheel 12. As the speed increases the weights B which are rotated from the countershaft through gears 13, 14, move outwards to clutch gear 14 to the engine and engage second gear, the engine then driving the shaft 15 through gears 14, 13, 5, 11 and freewheel 12, the freewheel 3 overrunning. As speed further increases, the weights C carried by shaft 15 move outwards to clutch the shaft directly to the engine and thus engage top gear, both freewheels 3 and 12 overrunning. A greater step-down ratio in first and second gears may be obtained by transmitting the drive from countershaft 4 to the shaft 15 through gears on a parallel secondary shaft 17, Fig. 3. This transmission is obtained by sliding ball-clutch sleeve 7, Fig. 1, to the right to allow the balls 6 to move out of grooves in the shaft 4 and thus disengage the gear 5 from this shaft a second ballclutch sleeve 9, Fig. 3, connected to the sleeve 7. being simultaneously moved to cause balls 16 to leave a recess in the sleeve and enter grooves in the shaft 17, thereby coupling gear 18 to a gear 21 on the shaft 17. Countershaft 4 then drives shaft 15 through gears 20, 21; 18, 19; and 19, 11. To engage reverse gear, the sleeves 7 and 9 are moved further to the right, whereby ball clutches 6, 16 are disengaged and a ball clutch 22 is engaged to couple gear 21 to gear 23, the latter gear directly driving a gear 24 on the shaft 15. For engine braking, the freewheel 12 is locked by sliding gear 24 to interengage corresponding claws on the gears 24, 11. The weights B, C each have pairs of balls 52 cooperating with spring-loaded wedges as described in Specification 702,796, and their outward movement is resisted not only by tie springs but also by axially-movable members controlled by additional centrifugal weights carried by the driving half 54 of the clutch so that the resistance to clutch engagement is influenced by engine speed, i.e. by throttle control, as described in Specification 711,212. Cushioning springs 56 are provided between the clutch hubs and the weight carriers.

Filed: 1973-05-14
Abstract: 1413716 Fastener driving tools DIETER HAUBOLD INDUSTRIELLE NAGELGERATE 14 May 1973 [16 May 1972] 22827/73 Heading B4C A trigger mechanism for a pneumatically operated nailing or stapling tool comprises a release lock having a release bar 11 axially movable from a first to a second position (upon for example, engagement with a workpiece), the arrangement being such that air flow through the trigger mechanism to a control valve 13 is prevented unless the release bar is in its second position before the release valve 15 is opened by actuation of a trigger 14 and that the air flow through the trigger mechanism is prevented if the release valve is opened by actuation of the trigger prior to movement of the release bar to its second position. The arrangement prevents firing if the release bar 11  is accidently moved while the trigger 14 is in its pulled position. As shown in Fig. 6, the trigger is pulled to permit the air in reservoir 3 to pass through passages 21, 23 in the release valve assembly and into a tube 12 through radial bores. Since the release bar 11 is in its upper second position and an annular piston 24 is in its upper position, the air can flow through radial and axial bores 28, 27 in the release bar to operate the control valve 13. If the trigger 14 is in its pulled position when the release bar 11 is in its lower first position the annular piston 24 complete with piston-ring is depressed by the air against the action of a spring 26 so that when the release bar is raised with the annular piston remaining depressed, the air cannot flow into the bores 28, 27. As soon as the trigger 14 is released to shut off the air flow, the annular piston moves upwardly to allow operation when the trigger is again pulled.
