Title: Improved card stacker
IPC: B65H31/22
Filed: 1963-03-26
Abstract: 977,953. Card stackers. INTERNATIONAL BUSINESS MACHINES CORPORATION. March 26, 1963 [March 27, 1962], No. 11888/63. Heading B6H. In a card stacker, the stacker pan 16 is pivoted to a shaft 15 mounted between the two uprights 14a of a U-shaped member 14 slidable vertically between two pairs of guide bars 13 fixed to the two vertical flanges 12 of a vertical transverse plate 11. Each flange 12 has two notches 17 and 18 enabling the stacker pan 16 to take either of two positions shown (one in broken lines). A second shaft 22 mounted between the uprights 14a carries a pair of rollers 21. The stub ends of the two shafts 15 and 22 ride in the space between each pair of guide bars 13, thereby retaining the U- shaped member for vertical movement only. For upward-delivery of the cards (i.e. stacking the cards with the first card remaining uppermost), the stacker pan 16 is retained by the notches 17 in the uppermost position. The first card 1 is delivered by rollers 19, 20 so that it rests at an angle in the stacker pan with its rear portion, supported by rollers 21, projecting at an acute angle across the path of the next incoming card. The second card 2 is fed under the first card 1, but due to friction between the cards, does not progress as far as the bottom corner of the pan 16. Axial grooves 23 in the top feed roller 20 lifts the trailing end of the second card 2 above the path of the next card 3. Friction between cards 2 and 3 feeds card 2 into the bottom corner of the pan, and the trailing end of card 3 is then lifted by the grooves 23 in readiness for the next incoming card. With the pan 16 in the lower position on notches 18, the cards are fed in by the rollers 19, 20 and fall to the bottom of the pan with the first card lowermost. With the U- shaped member 14 lowered to the bottom of the rails 13, the pan 16 may be tilted upwards about the shaft 15 for stowage.

A self-opening thread rolling head comprises two main sections, one of which includes freely rotatable threading rolls 9 on eccentric spindle 23 arranged concentrically about a workpiece, and a second main section consisting of a shank portion 3 and a workpiece stop 6, the first section comprising two main parts capable of relative rotation, one part being rotatable and axially slidable on the shank portion and the other part having a disengageable drive with the shank portion, axial movement of the first part relatively to the shank causing disengagement of the drive and consequent movement of the rolls out of their working position. In operation, a workpiece, after having a sufficient length of thread rolled on it, strikes the adjustable stop 6 to cause axial movement of the shank portion and disengagement of dogs 31 and 32. The parts 9, 10 of the first main section are then rotated by a spiral spring 30 relative to the part 8 and followers 28 on the eccentric roll spindles 23 follow a cam-track 29 to rotate the spindles and move the rolls 22 on their slightly skewed axes away from the workpiece. The roll bearing part 8 is splined to the shank 3, and the spring 30 gives an axial thrust to tend to engage the dogs 31 and 32. Another embodiment is shown in which a gear ring on the shank portion engages geared extensions of the roll spindles on axial disengagement of the two parts of the first main section, a handle 17 being provided as before for resetting the rolling head.

L. ; 208, Eason Avenue, Detroit, Michigan, U.S.A.) April 23, 1934, No. 12207. Convention date, April 24, 1933. [Class 52 (iv)] [See also Group XXV] The invention provides an upholstery or like panel installation comprising in combination a frame 18, Fig. 7, with stud-receiving apertures, a " form " 1 of cardboard or other stiff material provided with the requisite number of fastener retaining means 2, and fastening members, and a covering 4 of textile material on the face remote from that carrying the fasteners. The " form " 1 may have depressions 5 to receive the bases of the fasteners. The fastener retaining member 2 is in the form of a bridge-piece secured by prongs 3 upset within the material of the "form" 1. The fasteners used are of the kind having stud portions 9 of flat material, bent up in overlapping relationship and at right angles to a base portion 7. As shown in Fig. 3, the base 7 has a projection 10 which presents unintentional removal of the fastener by engagement with the edge of the piece 2, but can be forced under the piece 2 for intentional removal or attachment. The method of attachment allows limited floating movement of the fastener to ensure proper register with the stud-receiving aperture. In Fig. 3 the edges of piece 2 are of curved form, but a modification is described in which the edges are straight and one has a lateral slot in which the projection 10 may play. In a further form the piece 2 is narrow with straight edges and secured by a single prong at each end. Figs. 6, 7 show a further modification in which the piece 2 has an elongated aperture 15 with a relatively narrow lateral slot 16 through which the stud members 9 may pass edgewise, being then rotated to the position shown transverse to slot 16 to prevent accidental removal.

Abstract: 1,097,112. Pressure oscillation of gas during sorption and catalytic processes. ESSO RESEARCH & ENGINEERING CO. March 23, 1965 [April 28, 1964], No. 12318/65. Headings B1F and B1L. To improve the mass transfer of a multicarpment substantially gaseous or vapour phase to and/or from porous sorptive and/or catalytic material, the pressure over the porous material is oscillated during the mass transfer. The gaseous phase may be passed over a zeolitic molecular sieve bed during the adsorption step or the desorption step of a normal-paraffin separation process, the gas molecules being forced into and away from the interiors of the particles of the bed during oscillation of the pressure for more efficient adsorption or desorption. The pressure oscillation is effected by one of three methods; (1) constant input 2 'but oscillating restriction 4 in output 3, (2) constant output 3 but oscillating restriction 5 in input 2, (3) constant input and output with oscillating volume source connected to porous material (Fig. 2, not shown). The oscillation is preferably at a rate of 0.01 to 5000 cycles per second and a pressure of 0.01 to 2 p.s.i.

Filed: 1961-04-06
Abstract: 948,378. Spray-producers. IBIS ENTERPRISES Ltd. April 6, 1961 [April 6, 1960 ; Oct. 5, 1960], No. 12455/61. Heading B2F. A gun which sprays two different liquids simultaneously, but which do not mix within the gun, e.g. a resin and a catalyst, has an inlet 11 for the resin which, in the spraying position, flows from an annular outlet between the end of a hollow needle 28 and the outlet end of a cap 12, and an inlet 20 for the catalyst which, in the spraying position, passes through the bore 29 of the hollow needle. Both liquids are sprayed by compressed air supplied at 22 to a cylinder 21, and which flows through passages 48-52 and past an adjustable valve 53 to an air cap 14 and outlet 16. In the non- spraying position the hollow needle is urged forwardly to close the annular outlet for the resin, and a needle valve 33 is forced against a seating in the hollow needle to cut off the catalyst supply ; this operation is effected by a compression spring 27 in the cylinder which urges a piston 25 forwardly. Spraying is effected when the supply of compressed air to the cylinder forces the piston rearwardly and, since the needle valve is screwed to a part 24 of the piston and there is lost motion between the piston and the end of the hollow needle, the needle valve is opened a little before the hollow needle is raised from the annular outlet. A threaded abutment 38 adjustable by a control knob 38a limits the upward movement of the piston thence the opening of the hollow needle and the needle valve. Rearward movement of the needle valve from its seat 30 is also adjustable by a knob 35 which is turned to vary the threaded connection of the needle valve with the piston at 34. The knobs 38a and 35 have pointers 43 and 47 co-operating with indicia 42 and 46. In the embodiment of Fig. 3 the adjustment of the catalyst feed is provided by a valve 62, and the rearward movement of the piston is controlled by an abutment having an adjusting knob 66. In the device of Fig. 5 the catalyst is supplied at 84, and flows, under the control of a valve 83, through a passage 74b to a passage 79 in a needle valve 75 having openings 78 from which the catalyst leads into the hollow needle. As in the previously described guns there is lost motion between the piston and the hollow needle so that the needle valve is opened just prior to the rearward movement of the hollow needle.
