Title: Method of regenarting ion exchange material
IPC: B01J49/00
Filed: 1976-09-09
Abstract: 1519489 Regenerating ion-exchangers CLARKE CHAPMAN Ltd 9 Sept 1976 [16 Sept 1975] 37931/75 Heading B1J A method of regenerating ion exchange material in a vessel comprises passing liquid upwardly through the material and out of the vessel through outlet means and maintaining sufficient gas pressure in the vessel above the level of the liquid to maintain the level of the liquid sufficiently below the free surface of the material to suppress fluidisation of the material, gas being introduced into the vessel during regeneration only in response to rise in the liquid level above a datum which lies above the level of the outlet means, the introduction of gas increasing said gas pressure, and terminating the supply of gas after a period, the period being either predetermined, or being that period necessary for the liquid level to. reach the datum, gas pressure above that needed to hold the liquid level at the datum being relieved only partly and only when the liquid level falls to the outlet means and being relieved by flow of gas from the vessel through the outlet means only. When introducing gas for a predetermined period, this may be repeated until the required liquid level is attained. In a modification, gas introduction is stopped when the liquid level falls to a lower datum level also above the outlet means. The means for sensing liquid level may be responsive to change in the electrical conductivity of the layer of material on rise or fall of liquid level thereto. The layer of material above the outlet means can be inert.

Abstract: 1,169,768. Feeding and delivering sheets. INTERNATIONAL BUSINESS MACHINES CORP. 24 Aug., 1967 [7 Sept., 1966], No. 38936/67. Heading B8R. In a card processing machine in which cards 3 are successively passed from a feed roller arrangement 32, 33 to a delivery roller arrangement 40, 41, 42 through a reading station 1 and a hole-punching station 2 the movement of each card through the latter station is intermittent even though the gripper belt assembly 4, 6, 7, 15, carrying the cards moves continuously. The intermittent nature of the card movement through the punching station is derived from a continuously rotating cylindrical cam 30 which coacts with a pivoted arm depending from each gripper 15 to thereby oscillate the gripper while it passes along the cam. The oscillatory movement due to the cam 30 and the continuous movement due to the belt 4 superposed on each gripper causes each card 3 to oscillate backwards and forwards whilst the axis of oscillation continuously moves forwards, the oscillatory movement taking place in an arc. If desired the cam 30 may extend over the full length of the card path and only rotate when card oscillation is necessary. Pad members 37, 38 in the gripper path effects automatic opening of the grippers for the usual card feed and release functions.

Title: Improvements in or relating to the manufacture of pockets for garments
IPC: A41D27/20
Filed: 1962-10-22
Abstract: Seamless pockets for garments are made by weaving a tubular fabric having its two layers joined by single layer weaving along transverse zones containing thermoplastic synthetic resin yarns. Some of the single layer zones may extend only partway across the fabric; they may vary in width, either in steps to make tapered pockets, or in a succession of curves to made pockets with curved bottoms; these may be longitudinal single layer zones also.  The closed edges of pockets are formed by the edges of the tubular weave, and by cutting and heat sealing the fabric along the single-layer zones.  The fabric is cut across the two-layer zones to form the openings of two adjacent pockets.  Parts of the fabric may be reinforced by increasing the number of threads per inch. The weave may be open so that dust will not accumulate in the pockets.  The single-layer zones may be of distinctive weave or colour.

[Also in Divisions G1 and G3] In a machine, means for sensing the displacement of one end of a member 62, as a result of expansion or contraction of the member due to temperature variation, comprises a bar 102 of a material, having a relatively low coefficient of expansion, which is attached to the end and to means 117 for indicating the displacement. A machine spindle 62 is rotated in a quill 67 by a motor 75 controlled by a tape programming apparatus 130. The motor and spindle are carried on a slide 60 moved at controlled speeds by a motor 80 on a saddle 49 balanced by hydraulic means 53 and moved vertically by a motor 52 on a column 41 movable laterally on ways 42. The work is carried on an indexable table 68. The motor 80 moves the saddle by a screw 81 engaging a nut 82. Aligned with the nut 82 on the slide 60 is the synchro 117 which is rotated by rack teeth on the bar 102 whenever the front of the quill 67, to which the bar is attached, moves due to temperature variations. Movement of the synchro 117 modifies the movement of a fine synchro 141 in the tape control circuit 130. In a modification, the correction due to expansion is applied to the work-table instead of to the tool quill. In a final modification, the synchro 117 is replaced by a transducer 192, Fig. 4, or by a linear differential transformer, a strain gauge, or a variable inductor or capacitor.
