Abstract: 920,138. Screw pumps. DEKA S.A. May 9, 1961 [May 14, 1960], No. 16806/61. Class 110(1). In a pump the material to be pumped is continuously fed through a rotating tube where it is subjected to the action of a helix on the tube and a helix rotating coaxially with it, but in the opposite direction. The material, generally liquid or solids, is fed to a hollow rotatable tube f, either horizontally or, as shown, vertically from a hopper a. The material is pumped by a helix d carried by a shaft b and a helix e of opposite hand carried by the tube f. Shaft b is directly driven by a motor q while the tube f is driven in the opposite direction through the gearing shown. A helix c may be provided on the shaft b to assist in feeding the material into the tube f. Helices d and e may be rotated independently of each other and may be non-continuous and of a different pitch which may vary along each helix. The tube f has tracks g for rollers h of which there are at least three per track. The track g nearest the hopper a is grooved to locate the tube f axially. Bearing t and rings j and k provide water-tight seals.

Patent GB-274838-A (GB)
Title: Improvements in blank-transferring mechanism for nut-making and like machine tools
IPC: B23Q7/00
Filed: 1927-06-29
Abstract: 274,838. Muhlschlegel, K. July 21, 1926, (Convention date]. Nuts.-A work holding and transferring device adapted particularly for use in automatic machines for making finished nuts from bar stock, comprises a gripping head having a prismatic recess which receives the cut-off workpieces which are then transferred to successive working' stations for further operations. The nuts 2 are faced, bored and finally cut off by a tool 3 at the station 1. A swinging arm 6, mounted to move axially on a shaft 5, is provided at its end with a recess 11 shaped to fit the workpieces and cut away along one side at 12. The movement of this arm serves to transfer the blanks from the station 1 to a second working station 4, the extreme positions of the arm being determined by adjustable stops 8, 10, on the arm coacting with a fixed abutment 7. A pin 19 passing through the head 11 is provided with grooves 20, 21, coacting with a spring plunger 22 and with a reduced forward portion 19<1> adapted to enter the bore of a nut. In operation, after the drill 24 has been withdrawn from the work-piece, the arm is in the position shown in Fig. 2 and by axial movement of the arm on, the shaft 5 the end of the pin 19 is pressed into the bore of the nut before completion of the cutting-off operation. The arm is then swung over towards position 4 and during this movement the nut is first positioned by a spring-mounted lever 17 and on further axial movement of the arm the nut is pressed into the recess 11 by a guide 18 and the pin 19 is moved back. When the nut reaches the position 4, a further axial movement presents it to a countersink 27 which enters the bore of the nut and forces the pin 19 to its end position, Fig. 8. On completion of the countersinking operation, the arm 6 is axially withdrawn and the nut may be removed by an ejector engaging in a slot 28 in the head. At the same time the pin 19 engages a fixed abutment 23 and is thereby forced forward in readiness to pass into another work-piece. In some cases the arm 6 may be moved to carry the nut from the countersinking tool to a third station where the nut is presented to a curved shank tap for the threading operation. Bolts.-The device is also applicable to convey screw bolts to a head-slotting tool and in this case in place of the pin 19 a hole is bored in the head 11 to receive the shank of the bolt.

Title: Aqueous regeneration of silica gel
IPC: B01D15/08
Filed: 1961-05-12
Abstract: A silica gel adsorbent saturated with a water immiscible multi-component organic liquid consisting of a less polar component (percolate) and a more polar component (adsorbate) is regenerated by introducing sufficient water into the adsorbent to displace the percolate without desorbing the adsorbate, desorbing the adsorbate by contacting the percolate-free adsorbent with a polar desorber consisting of a polar organic liquid and drying by heat at 250 DEG -800 DEG F., the <PICT:0925921/III/1> p  evacuated adsorbent to render it suitable for further use.  The adsorbent may be a silica gel bed and water may be added to the adsorbent in amounts at least equal to the bed weights.  The organic liquid may contain N compounds, single ring or polynuclear aromatic compounds, olefines paraffins, cracked naptha or lubricating oil.  The desorber may be a polar solvent such as alcohols, e.g. ethanol or ketones, e.g. methyl ethyl ketone or acetone.  The organic liquid is fed via line 2 and valve 2 to bed 3 and the percolate is fed via lines 4 and valve 5 to receiver 6, until it is no longer pure enough when valves 2 and 5 are closed and the organic liquid is fed via line 1 and valve 7 to bed 9 and the percolate via line 10 and valve 8 to line 4 and receiver 6 again.  Bed 3 is regenerated by shutting valves 11-15 and feeding H2O via line 21, valve 16, line 22, valve 17 to bed 3 and via line 4, valve 18, line 23, valve 19, line 24 and valve 20 to tank 25 where the displaced percolate is decanted via line 44 to receiver 6 and H2O is run off at 35.  For desorption valves 16 and 20 are closed and the desorbent is fed via lines 21 or 36, valves 11 or 26, line 22 and valve 17 to bed 3 (the route flow depending on whethe it contains H2O or not) and then via line 4, valve 18, line 23, valve 19, lines 24 and 27, valve 14 to tank 28 where the mixture is decanted via line 29 to tank 30 for use as desorber or fed via valve 31 and line 32 to still 33 where desorber is recovered at 34 and H2O at 35.  The H2O may contain adsorbate which can be recovered.  When adsorbate has been removed from the gel, valves 5, 11 and 18 are shut, and while bed 3 is heated by line 38, e.g. to 250-400 F, steam is passed through evacuator 37 to entrain vapours from bed 3 via valves 17 and 45 and the desorber is removed via condenser 43 to tank 30. Valve 45 is then closed and air passed via line 41, valve 15, line 22, valve 17 to bed 3 and then via valve 40 to exhaust at 42.  Bed 9 can be regenerated similarly while bed 3 is in use for percolation.

Filed: 1944-09-13
Abstract: In a fluid treatment of filamentary material, liquid or gas is passed through a pipe 6, Fig. 1, into a housing 4 to be applied to filamentary material F which is passed in a helical path around a reel 3 and is thrown out by centrifugal action from the latter to be deflected by the inner surface 7 of the housing 4 back to the advancing thread.  The treating fluid is collected eventually in channels 8 at each end of the housing 4 and may be recirculated through pipes 10 via a pump to the pipe 6.  To counteract the tendency of the fluid to advance in the direction of the thread, the inner surface of the housing 24, Fig. 4, is provided with a helical groove 27 which tends to move the fluid from right to left, whilst the thread moves from <PICT:0594129/IV/1> <PICT:0594129/IV/2> left to right.  The inner surface of the housing may have a diamond pattern knurling, or it may be of frusto-conical shape with its widest part at the end of the housing at which the thread enters.  Alternatively, the deflecting surface is cylindrical, but with its axis inclined with respect to the horizontal reel and downwardly towards the end at which the thread enters the housing.  In modified apparatus, the reel and housing may be mounted vertically, and/or the housing may comprise a number of inlet and collecting grooves by means of which a plurality of treating fluids may be applied to the thread at different zones of the reel.  In the case of treatment with a gaseous fluid, the latter may be introduced through perforations in the axle of a reel to pass through the helical windings of the thread to be deflected by the inner surface of the housing Specification 594,130 is referred to.
