Abstract: 1,084,105. Hopper wagons. ETABLISSEMENTS ARBEL, and P. ARBEL. Nov. 6, 1964 [Nov. 7, 1963], No. 45321/64. Addition to 996,628. Heading B7L. An improvement in or modification of the invention described and claimed in the parent Specification consists in the provision, in lieu of a lug on the arm 28 and a detent on the wagon frame, of a latch 76, Fig. 1, pivoted to a lever arm fixed to the master trap door 5 and having a hook 77 to engage an abutment 78 on the hopper wagon frame to retain the door 5 open after the adjacent supported door 4 is released for closing by engagement of the roller 29 with the track ramp 31. During the final closing movement of the supported doors 4, 6 the door 6 releases the hook 77 from the abutment 78 to permit the master doors 3, 5 to close. In the form shown in Fig. 4 the master door 5 is retained in the open position after release of the doors 4, 6 by a hook 82, on a bellcrank 80 pivoted at 81 to the wagon frame, engaging a retaining member 83 on the door 5. A stud 84 on the bell-crank 80 is slidable in a slot 79<SP>1</SP> in an arm 79 pivoted to the adjacent supported door 4. As the latter moves to its closed position, after its release by the roller 29 and ramp 31, the arm 79 can pivot on the door 4 and slide relative to the stud 84. When the stud 84 engages the end 85 of the slot 79<SP>1</SP> further movement of the door 4 rocks the bell-crank 80 to release the hook 82 from the member 83. The latch 25 with its hook 26 for retaining the doors open may, in both embodiments, be pivoted to the door 4 so that the hook can engage a fixed point on the wagon frame. The member 30 would then be dispensed with.

In a process for regenerating exhausted ion exchange material in ion exchange apparatus which includes a container in the lower region of which is a bed of particulate ion exchange material at the upper end of which bed is a collector having entry means for liquid, regenerant treating liquid is passed continuously and upwardly through the bed and out of the container through the collector whilst pressurized gas, for example air, is provided in the upper region of the container to depress the static head of liquid existing above the entry means of the collector to a level at which fluidization of the bed is inhibited, the gas being fed continuously into the upper region of the container at a pressure in excess of that pressure required to maintain the liquid at the depressed level and being released continuously from the upper region of the container at the depressed level of the liquid in order to relieve the upper region of the container of excess gas pressure. It is preferred that the depressed level of the liquid lies below the surface of the bed and that the gas is released from the container with the regenerant treating liquid through the collector. The bed may include a single layer of cation exchange material or a single layer of anion exchange material or superposed layers of weakly acidic and strongly acidic cation exchange material or superposed layers of weakly basic and strongly basic anion exchange material. The bed also may include a topmost layer of inert particulate material in which the collector is embedded. A bed including cation exchange material, in the form either of a single layer or of superposed layers of weakly acidic and strongly acidic material, may be connected in series with a bed including anion exchange material in the form either of a single layer or of superposed layers of weakly basic and strongly basic material; such an arrangement may be used in the deionization of water. Any such bed or combination of beds may be used in conjunction with a bed including an intimate mixture of particulate cation exchange material and particulate anion exchange material.

Building elements comprise apertured members 1 and pins 3 for holding such members together. The apertured members 1 are preferably in the form of rectangular open-ended boxes, the four walls of which have opposing square apertures 2. These members may also be flat strips, with similar apertures. The pins 3 are of square a cross-section which snugly fits into apertures 2, and have one or more lateral grooves 5, extending round them such that when the groove is in line with the wall of the member into which the pin is inserted, it can be rotated. The walls 6 of these grooves taper towards the bottom of the groove so that the inner width 2d 1  is about 0.2 mm narrower, and the outer width 2d 2  is about 0.2 mms wider than, the dimension 2d, where d is the wallthickness of the apertured members. The pins also have cylindrical ends 9, rotatable in apertures 2, provided with cruciform or square recess on their end faces, for receiving a tool to rotate the pins. Thus when two apertured members are placed adjacent to one another so that their apertures 2 are aligned, a pin 3 can be inserted through both said members and when groove 5 is in line with the adjacent surfaces of said members, it can be twisted so that the protruding corners of the groove 5 overlap the sides of the square aperture 2; and due to the tapered nature of the groove, the members are pulled tightly together.

Abstract: 1,256,902. Feeding webs. EASTMAN KODAK CO. 20 Dec., 1968 [22 Dec., 1967], No. 60658/68. Heading B8R. [Also in Divisions G2-G3] A web-handling apparatus, such as a motion picture projector having automatic rewinding means described in Specification 1,254,705 has in addition means for sensing the initial diameter of film on a cartridge spool before projection and storing the information so that the rewind speed of the cartridge spool may be adjusted accordingly after projection. The film stripping mechanism comprising a driven belt 28 is movable into the cartridge containing a spool 16 to contact the outer film convolution and discharge the film end from the cartridge. Attached to the belt assembly is an arm 60 which positions a second arm 49 along a ratchet bar 53 according to the position the belt assembly attains on contact with the film. For this purpose ratchet bar 53 is momentarily moved laterally by means of a solenoid 55 energized when the belt 28 moves into the cartridge. The other end of the arm 49 is slidable along rod 54 and is biased downwards by spring 51. The arm 49 carries a contact 48 slidable along resistance wire 47 mounted on an extension of arm 40. The arm 40 is pivotable about an axis 41 so that different spool sizes may be used and the relocation of the slide wire 47 relative to the contact 48 compensates for the size difference. The slide wire 47 is connected through rectifiers 64, 65, 66 to the rewind motor 68. It can be seen that when the belt 28 moves out of the cartridge after the stripping operation, contact 48 is retained in a position indicative of the amount of film on the cartridge spool. In a second embodiment, the resistance wire 47 is mounted on a fixed member 45 and the fixed resistance 63 is replaced by a variable resistance (72), Fig. 5 (not shown), whose contact (74) is positioned by a mechanical linkage (76) coupled to a sensing device (78) adapted to engage a code (80) in the base of the cartridge indicative of the cartridge size. In further embodiments for use with cartridges containing a full supply reel, only a code on the cartridge is sensed, Figs. 6 and 7 (not shown). A programming system may be added to decrease the rewind speed as the film roll increases in diameter during rewind, Fig. 8 (not shown).
