Abstract: 599,480. Shaping. BECHLER, A. Sept. 18, 1945, No. 24110. Convention date, Feb. 20. [Class 83 (iii)] A machine for shaping cam profiles comprises a planing-tool reciprocating at right angles to the direction of movement of a work holder carrier on which is mounted a cross-slide with control means carried thereon which co-operate with abutments to effect movement of the carrier upon displacement of the cross-slide. The work-carrier 20 is slidably mounted on a base 18 longitudinally adjustable on a bed 1 which supports a pillar 5 containing the drive to a vertically reciprocating tool carrier 8, the tool-holder 11 being adjustable around the axis of its securing bolt 12. The work 25 is mounted on an arbor 24 rotatable through worm gearing by a hand wheel 28. The longitudinal displacement of the work is effected by spring pressure between the carrier 20 and the tailstock portion 23 of the base 18 in which a roller 21 coacts with the straight face 39 of a calibrated plate 35 angularly adjustable and transversely slidable on the work-carrier. By operating the hand wheels 28 and 32, the cam profiling is manually controlled. In the profiling of cams of true spiral form, the hand wheel 32 is geared to the hand wheel 28, in which case the relative slide movements are mechanically controlled. For machining bellhousing cams, the arbor is constructed as a right-angled bevel drive, whilst for dealing with cams having lobes the tool-holder 11 is rotatably positioned.

Title: Method and apparatus for purifying gaseous mixtures by cyclic adsorption
IPC: B01D53/04
Filed: 1963-06-20
Abstract: <PICT:1044161/C1/1> A pure nitrogen stream is obtained from the combustion products of burning a hydrocarbon fuel in air, adsorbing a major proportion of the contaminants in an absorbent, recovering a partially purified effluent therefrom, further adsorbing part of the remaining contaminants from the effluent in another adsorbent material, recovering a further purified gas, stopping adsorption in one of the adsorbents and purging the contaminants from the adsorbent with a portion of the further purified gas.  A gas stream, e.g. nitrogen containing combustion products, e.g. CO2, water vapour, C2H2, SO2 and oxides of nitrogen; of a hydrocarbon fuel, e.g. burned in air, may be treated to give a substantially pure nitrogen stream which will only contain the inert gases, alternatively the purified effluent may contain combustibles, e.g. CO and H2 but these can be removed.  The adsorbent material may be active C, glass wool, certain metal oxides, clay, fuller's earth, diatomaceous earth, bone char but preferably silica gel, activated alumina, microtraps, Mobile-beads and molecular sieves particularly of the type zeolite A having 4<\>rA pores although 5A molecular sieves are also specified.  In a specific embodiment (the Figure) a nitrogen-rich gas stream having 5-20% CO2 and saturated with H2O vapour at 50-100 DEG  F. enter surge tank 26 at 40-150 p.s.i.g. but preferably above 60 p.s.i.g., and passes through line 28 to valve 24 where it enters adsorber vessel 8 having a bed of 4A molecular sieve of particle size 1/16 -inch. The adsorber unit 2 operates on a short cycle of 30 seconds 5 minutes per adsorber vessel.  The partially purified effluent passes to the second adsorber unit 4 through valve 18, line 20, and check valve 21 to valve 54 whence it enters adsorber vessel 46 wherein the remaining CO2 and water vapour are removed by a bed of 4<\>rA zeolite.  The second adsorber unit 4 operates on long cycles of 1-5 hours and has electrical heaters 48 and 50 in beds 53 and 51, respectively, to compensate for heat losses particularly during desorption.  Steam may be used for indirect heat exchange.  The highly purified effluent leaves adsorber 46 by valve 56, line 66, check valve 68, flow regulating valve 70 and product line 72, valve 74 acts upon a back pressure regulator to maintain the pressure in the adsorber 66.  Part of the purified effluent 1/4 -\ba1/2 , is diverted to manifold 82 and used to purge beds 5 and 53 by means of lines 86, valve 18, and line 14; and line 84, valve 56 and line 76 respectively, after having its pressure reduced. In the adsorber unit 2, valves 18 and 24 are linked to pneumatic cylinder 36 which is actuated according to the position of a solenoid valve 38 using impure feed gas whilst the valves 54 and 56 of the second adsorber unit 4 may be operated in a similar manner by cylinder 58 and solenoid valve 60.  The solenoid valves 38 and 60 together with heaters 48 and 50 are controlled by a programmer.
