Title: Improvements relating to apparatus for the recovery by adsorption of gases, vapours or liquids
IPC: B01D53/04
Filed: 1931-12-08
Abstract: <PICT:0397128/III/1> <PICT:0397128/III/2> Apparatus for the recovery of gases and vapours by adsorption in materials such as active charcoal comprises an annular container b for the adsorbent material which is mounted eccentrically in a cylindrical casing a, and the top of this container is provided with a steam jacket a<3> to prevent condensation of the steam used for the recovery of the adsorbed material.  The inner and outer walls of the container are perforated so that the gases entering through the inlet c readily pass through the filter bed via the annular space h and are withdrawn from the central space b<1> by the valved outlet b<2>.  A deflecting plate e which is concentric with the centre of the container b is placed opposite the inlet c and midway between the casing a and the outer wall of the container b.  The top plate a<1> is provided with a circular baffle a<6> to prevent passage of gases over the top of the adsorbent material.  The gases may be passed in the reverse direction through the adsorbent material.  To recover the adsorbed material the inlet and outlet valves are closed and steam, preferably superheated, is passed through the apparatus via the inlet j and outlet k or in the reverse direction.  To avoid accumulation of moisture at the bottom of the container b, the bottom plate b<3> may be raised above the bottom of the annular space h.  The apparatus is particularly applicable to solvent recovery from air, the gases being passed through the filter bed by pressure, pressure and suction, or preferably suction only.  Suitable coils for the passage of a heating or a cooling medium may be provided to allow temperature control in the different stages in the adsorption process.

Abstract: 959,733. Strap tensioning tools. FMC. CORPORATION. Sept. 5, 1962 [Nov. 15, 1961], No. 34069/62. Heading F2G. A strapping tool comprises a housing 10-11 with a guide 27 through which a strap (not shown) is pulled to tighten it around a package by engaging means 26 moved by a motor 22 inside the housing; the motor being controlled by a member 43 manually movable to a first position where it causes the motor to rotate the means 26 but normally held by spring 47 in a second position where it stops rotation of the motor; there also being a handle 37 on the mounting which operates a cutter 30 when moved to a first position (dotted line in Fig. 1) whence it is urged by a spring (Fig. 3, not shown) to a second position where it can hold the member 43 in the latter's first position. Fluid pressure from pipe 16 passes inside the tool handle 12 along conduit 14 to the valve 15. The member 43 operating the valve 15 has longitudinal movement limited by a set-screw 46 in a slot 45 and when pressed inwards against the spring 47 connects the conduit 14 to the motor 22 by way of a notch 48 (Fig. 6) and conduits 17, 18 and 20. To use the tool the end of the strap is inserted through the slot of the guide 27 with a seal thereon abutting the nose 28 whilst another portion of the strap is also passed through the slot at 27 and engaged in the slots in the windlass at 26. The member 43 is then pushed inwards to start the motor and rotate the windlass 26. The leg 38 of the handle 37, urged by its spring engages a notch 50 (Fig. 6) to hold the member 43 operative. Although the motor will stall, tension continues to be applied to the strap until the leg 38 is disengaged from the notch by moving the handle 37 to rotate the cutter 30 clockwise to cut the strap (Fig. 2).

Inventor: FREEMAN EBEN WINTHROP
IPC: D21G7/00
Filed: 1959-10-08
Abstract: 862,115. Coated paper. WARREN CO., S. D. Oct. 8, 1959, No. 34128/59. Class 96 Cast-surface or slip-finished mineral coated paper is made by directing steam against the coating to displace air, the heated, moist coating being thereupon pressed, e.g. by a rubber or rubber-covered roll 2 against the surface of e.g. a chromium-plated dryer drum 1. The steam may be supplied by a slitorifice nozzle 5 against the paper 3 or into the nip where a pool of water 6 may accumulate and/or water &c. may be supplied to the nip. If only water &c. is thus supplied, it is boiled vigorously by contact with the drum 1 to generate steam at the nip and prevent water, as well as air, from being carried through the nip. The temperature of the roll 1 may be 80‹ to 140‹ C. An Example (1) mentions a coating mix of clay, calcium carbonate, casein, styrenebutadiene latex, and sulphonated tallow as a release and anti-foam agent. Another Example (3) mentions a mineral coating mix superposed on a paper having a dry, base coat. The steam which may be super-heated or not may be directed against a wet or dry coating.

Title: Method and apparatus for duplicating cam discs
IPC: B23Q15/10
Filed: 1969-07-07
Abstract: 1,211,995. 995. Template followers. EBAUCHES S.A. July 7, 1969 [July 10, 1968], No.34214/69. Heading G3N. [Also in Division B3] In a method of and machine for copy machining cam discs a blank disc 3 is mounted coaxially with a cam template 5 on a variable speed rotary support 1 and a tool such as a milling tool 9 or an electroerosion tool is radially positionally controlled by copying means 12, 13 to machine a groove in the disc 3 corresponding to the shape of the template, the tool 9 being advanced axially until it penetrates through the disc 3 over the whole periphery of the resultant cam. The electric control circuit is arranged to control the speed of relative advance of the tool along the cam periphery at a constant value. Radial movements of carriage 6 on which the milling tool 9 and its drive motor 8 are mounted are effected by a screw 10 driven by a motor 11 energized by the output of an amplifier 15 in dependance upon the transducer 12. A variable speed motor 21 drives the work support 1 through gearing 22, 23 and also a generator 20 whose output # is proportional to the rotary speed of the work 3 and is fed to a potentiometer 17 controlled from the lead screw 10 in dependance upon the radius at which the tool 9 is positioned, the resulting output being proportional to the tangential component #r of the tool velocity. A generator 16 driven from motor 11 provides an output proportional to the radial component dr/ dt of the tool velocity and is connected to a correcting circuit 24 also receiving a reference voltage input Vc the value of which corresponds to the desired constant velocity of the tool relative to the cam surface. The output of circuit 24 is fed to one input of an amplifier 26 which also receives the input #r from potentiometer 17. The output of amplifier 26 energizes motor 21 the speed of which is therefore held at a variable value ensuring constant relative speed of advance of the tool 9. The workpiece 3 may be fixed to the rotary support plate 1 by adhesive, and discs 4 of a material softer than the workpiece 3 may be disposed between it and the plate 1 to allow complete penetration of the tool 9 through the work.

Abstract: 911,023. Winding yarns; building motions. ROSENKRANZ, C-G., HALSTENBACH, H., and PLUTTE, A., [trading as HALSTENBACH & CO.]. Oct. 10, 1960 [Oct. 10, 1959], No. 34651/60. Class 120 (2). A machine for winding yarns on to bobbins has an eccentric lifting wheel 2, Fig. 2, that oscillates a traversing rod 5 carrying a yarn guide 7<SP>1</SP>, there being a movement of play, in the direction of movement of the rod 5, between the eccentric wheel 2 and the rod 5, to provide traverse movement beyond those positions at which reversal of the rod 5 would otherwise occur. This arrangement is stated to cause the yarn at the ends of the conical winding layers to be laid crosswise as strongly as at other positions of the winding. As shown two yarn guides 7, 8 are carried by rods 5, 6 reciprocated by the lifting eccentric 2. The eccentric 1 oscillates a lift arm 9 carrying sleeves 21, Fig. 3, slidable on the rods 5, 6 between abutment discs 22, 23, there being a weak spring 28 between the sleeve 21 and the disc 22. As the sleeves 21 are moved forwardly they first compress the springs 28 due to the inertia of the traverse rods 5, 6 and at the end of the forward stroke of the sleeves 21 the springs 28 push the traverse rods 5, 6 onwardly through a small additional amount. During the return stroke of the sleeves 21, each sleeve presses against its buffer disc 27 until, at the end of the return stroke of the sleeves 21, the inertia of the traverse rods 5 or 6 compresses the buffer springs 28 so that the traverse rods 5, 6 again move onwardly by a small amount. The lifting eccentric 2 is itself oscillated by an auxiliary eccentric 4, and driving pinions 29, 30 on the traverse rods 5, 6 rotate the rods in threaded engagement with the yarn guide carriers 7<SP>1</SP>, 8<SP>1</SP> so that the yarn guide carriers undergo an axial movement relative to the traverse rods 5, 6.
