Abstract: 528,440. Closing collapsable tubes. JOHNSON, B. A. E., and AKTIEBOLAGET G. AREHNS MEKANISKA VERKSTAD. June 16, 1939, No. 17646. [Class 94 (i)] [Also in Group XXII] A method of sealing the folded end of a collapsable tube consists in coating the folded end with a cement, liquid, fused metal, or other sealing medium capable of entering the folds. The folded end may be dipped into the sealing liquid, or the liquid may be applied by brushing. The tubes are placed in the pockets 2 secured to the links of a conveyer chain 3 which is moved step by step to carry each tube beneath a filling device 8 and folding devices 9, 10, 11. The tube is then inverted and its folded end is carried through sealing liquid in.a container 15, a guide bar 12 being provided to engage the caps to prevent the tubes from falling out of the pockets 2. In a modification, the pockets are pivoted to a conveyer chain which runs in an horizontal plane, cams being provided to move the links to invert the tubes. The folded ends are successively dipped into soldering paste or other suitable flux, into Wood's metal or a type metal to serve as solder, and then into warm water. Rotary brushes apply the flux and the solder and then remove excess solder &c. with the aid of the warm water.

Title: A gumming device for envelope blanks and the like
IPC: B31B19/00
Filed: 1935-06-21
Abstract: A machine for gumming a blank moving at a predetermined speed comprises means rotatable at a different predetermined speed for charging a rotatable applicator with gum, and driving means for imparting a continuously controlled variable rotation to the applicator, during each cycle of its operation, at different speeds correlated respectively to the speed of the blank and the speed of the charging means.  Blanks are fed by a chain 10 to a table 12 whence they are conveyed to the bight of two pairs of travelling belts 16, 17, 16<1>, 17<1>.  Gumming is performed by a segmental die 25 which presses against the blank while it is supported upon a bed cylinder 26a.  The die 25 is charged with gum from a <PICT:0458686/III/1> <PICT:0458686/III/2> transfer roll 26 and a pick-up roll 27, and is mounted on a shaft 42 which is driven from gears 38, 40 through the medium of links 50, 52, an arm 53 and a collar 53a.  A cam-following roller 58, mounted on the pivot 56 connecting the links 50 and 52, runs in a stationary cam track 59 which is so shaped as to cause the die 25 to move rapidly, and without slip, while it is applying gum to the rapidly moving blank, but to move slowly, and without slip, while it is in contact with the transfer roll 26.  This enables the pick-up roll to be driven slowly, thereby preventing the beating of air into the gum.

Title: Improvements connected with the take-up motions of looms for weaving
IPC: D03D49/20
Filed: 1926-07-20
Abstract: 274,639. Wilkinson, H. July 20, 1926. Take-up motion.- When the weft breaks &c. and the weft fork lever B is operated thus operating the starting handle A to stop the loom, a projecting member F adjustably fixed to a bar E adjustably fixed to a depending flat bar D adjustably carried by a bracket d on the lever B acts on an arm G and thereby releases the take-up motion catch to stop the take-up. Moreover a rod K adjustably carried by a bracket H on the starting handle II is owing to the movement of this handle A to the right, carried behind the bar D and prevents the, return of the take-up devices to operative position until the handle A is moved to restart the loom. The beam may be stopped by means of the handle A, without affecting the take-up devices since in this case the rod K passes in front of the bar D, the weft fork lever not having been operated.

Abstract: 516,352. Catalytic apparatus ; catalysts. JOHNSON, G. W. (I. G. Farbenindustrie Akt.-Ges.). June 20, 1938, No. 18265. [Class 1 (i)] [Also in Group IV) In the catalytic production of hydrocarbons having more than one carbon atom from carbon monoxide and hydrogen in the presence of a liquid medium, the medium is introduced into different zones of the catalyst chamber at separate points. The liquid medium may travel in the same direction as the gases or in counter-current. In Fig. 1 the liquid medium is supplied by a pipe f through a heat-exchanger b and heater i to the catalyst chamber a together with the reaction gases supplied through a pipe g. 'Fresh liquid medium is supplied by the several pipes h. The reaction products and liquid medium leave the catalyst chamber at k and pass through the heat-exchanger b to a separator d from which liquid is withdrawn for circulation by the pump f and the remainder leaves at together with water which forms a lower layer. In Fig. 2 oil from a heat-exchanger A and heater W is passed into the catalyst chamber K at H together with the gas mixture from a pipe G, the products and the liquid medium passing out at E to a separator S from which excess oil and water are withdrawn at B, the remainder being circulated by a pump P back to the chamber K through the heat-exchanger A and heater W. When the temperature in the upper part of the chamber K exceeds 295‹C., a part of the oil is branched off at V and led to the chamber K by a pipe R. The catalyst is prepared by fusing or sintering iron with small additions of titanium oxide, manganous oxide and potassium hydroxide in a current of oxygen and heating the product in hydrogen at 650‹C. Specification 468,434 is referred to.

Class 135 A hydraulic servomotor comprises a doubleacting piston 22 movable in a cylinder 21, a control valve having co-operating rotary and reciprocating ported members 62, 60 to control the relative magnitude of hydraulic pressure on opposite sides of the piston, and resilient means such as the spring 28 arranged to exert an increasing reaction on the piston as it is moved in either direction from an intermediate position in its travel, the piston being moved an axial distance which is related to the arcuate movement of the rotary ported member. The members 62, 60 are formed as sleeves the inner of which is fixed to a tapered extension 41 of the piston rod 24. The outer sleeve 62 is formed with pairs of ports 65, 65 and 66, 66 connected by galleries 67 in a rotary valve body 64. The sleeve 60 has six ports 61 in the shape of a rhombus. The ports 65, 66 are in the shape of,a parallellogram. The piston rod 24 and its extension 41 have three axial passages 47, 48, 49 connected at one end by radical passages 50, 51, 52 to three adjacent ports 61. The passages 50, 51, 52 are connected to the diametrically opposite ports 61 by two U-shaped grooves 53, 55, Fig. 4, and an extension 51a of the passage 51. The axial passage 47 has a radial extension 57 permanently connected to an exhaust port 46 through grooves 43, 45 and a passage 44. The axial passage 49 is similarly connected with a source of hydraulic pressure through a radial passage 59a and a port 42. The third axial passage 48 is connected with the remote side of the piston 22 through an inclined passage 58. The piston 22 is normally centered by the spring 28 which surrounds a piston rod 23 of less diameter than the rod 24. The compression of the spring 28 between flanges 29, 31 is limited by a distance sleeve 30 loose on the rod 23. The spring 28 is confined by a flange 35 directed inwardly from a cage 34. A distance piece 33 moves with clearance in the flange 35. Fig. 3 shows the ports 61, 65, 66 in the neutral position of the valve. On rotation of the sleeve 62, each pair of ports 65, 65, and 66, 66 coincides with two of the ports 61 whereupon the piston 22 moves until the ports no longer coincide. As applied to the control of a variable delivery pump, the piston rod 23 is connected to a cross head 20 of the pump and the rotary valve body 64 is connected by a coupling adapter to an electric torque motor. The cross head 20 controls the eccentricity of a normally fixed disc round which the pump plungers rotate.
