Filed: 1971-04-19
Abstract: 1300184 Radiation filters MEDINOVA AB 19 April 1971 [9 Feb 1970] 21327/71 Heading H5R An adjustable filter for use between the radiation source and the film in a radiographic apparatus, for reducing excessive variations in exposure over different portions of the radiograph due to variations in the thickness or absorbtion properties of the object under examination, includes absorbing members 8 and 9 which are pivotally connected to one another by a joint 11 which is constructed to present a substantially constant absorbtion for radiation directed perpendicular to the paper, regardless of the amount by which the members are rotated about the pivots. As shown in Fig. 3, the joint ends of members 8 and 9 are curved in arcs about their respective pivot axes 8a and 9a, and exhibit projections shown as 8b and 9b on Fig. 4. As shown in Fig. 4, both members 8 and 9 taper, but in opposite directions, in an S-shaped curve from that side of the filter at which the pivot axes 8a and 9a are located, such that their overlapping end portions may move over one another (Fig. 5, not shown), a third absorbing member 17 being mounted between them, such that rotation of either member about its pivot leaves the total thickness of absorbing material at the joint unchanged. In order to avoid displacement of the energy distribution spectrum of the radiation by the filter, a substance is used for the latter which has a K-absorbtion edge located within the energy distribution, and preferably close to the energy value corresponding to maximum intensity; a rare earth metal is preferred.

Title: Tracking Apparatus for a Moving Web, Belt, etc.
Inventor: SLEZAK RAYMOND JOSEPH
IPC: D06C3/00
Filed: 1967-05-08
Abstract: 1,162,566. Endless conveyers; feeding webs. R. J. SLEZAK. 8th May, 1967 [19 May, 1966], No. 21346/67. Headings B8A and B8R. A mechanism for tracking a conveyer belt 20 comprises a pair of rollers 31 rotatable on shafts 32 which are keyed to pivot arms 35. These arms are freely connected to pins 28 provided on frame members 12 of the conveyer and are normally perpendicular, the arm at one end of the roller shaft extending in opposite direction to that at the other. When mistracking of the belt occurs, the ends of the rollers 31 toward which the belt has tracked swing about the pins 28 in the direction of travel of the belt and the other ends of the rollers swing in the opposite direction, thus tending to return the belt to its central position. To improve this returning action friction discs 50 may be secured on the shafts 32. A further auxiliary arrangement comprises a fluid actuator 60 for pivoting one pair of the arms 35, the actuator being controlled by a sensor 71, 72, positioned adjacent the belt 20. It is stated that a single tracking roller may be sufficient. In a modification, Fig. 7, a friction disc 150 houses a planetary reduction gear system 160 which, when the disc is rotated by the mistracking belt 120, causes an arm 135 to swing about a pin 128 and the roller 131 to correct the tracking. A corresponding arrangement is provided at the other end of the roller. In a further modification, Figs. 10, 11 (not shown), by providing a link (294) between pivot arms (235) of two tracking roller assemblies (230), only one friction disc (250) is required. The apparatus is also applicable to web, strip, film or other elongate material on a roller system.

Title: Improvements in or relating to a process for removing the air contained in casein solutions of high viscosity
IPC: D01F4/00
Filed: 1943-12-21
Abstract: Air is removed from a highly viscous sodium caseinate solution, containing about 25 per cent of casein, which is to be used in a dry spinning process for the production of artificial threads, by raising the temperature of the solution to about 50 DEG  C. in a closed vessel having a volume several times that of the solution, reducing the pressure until the solution begins to boil and foam, and continuing the reduction of pressure until the air is substantially completely removed, this stage being indicated by the disappearance of the foam when the pressure is slightly increased.  In view of the large capacity of the vessel, the foam which is produced during the earlier part of the treatment is unable to foul the outlet for the air.  When the boiling begins, the air bubbles act as a nucleus for vapour formation and the larger bubbles which are formed burst sooner when they reach the surface.  After some time, the foam starts to break down and the vacuum may be increased.  In an example, sodium caseinate is dissolved in dilute caustic soda and the solution is placed in a vessel having a capacity of about 6 times that of the solution. The solution is heated to 50 DEG  C. and the pressure is reduced to 16 centimetres of mercury.  As the foam subsides, the vacuum is increased until the solution is completely freed of air.

[Also in Group XVII] In a conveyer system for bottles and similar receptacles consisting of a rotary conveyer fed from another conveyer by a transfer wheel, the rotary conveyer and the transfer wheel both consist of peripherally grooved discs, the bottles being carried by the grooves, and only the transfer wheel is driven, the rotary conveyer being driven by the bottles carried by the grooves of the transfer wheel engaging the grooves of the rotary conveyer during transfer. The rotary conveyer is thus driven only so long as bottles are present. The grooves in the two rotary members may be arranged to accommodate the bodies of the bottles but preferably engage the necks which are of more standard size, as is shown. The transfer wheel 3 transfers the bottles by the grooves 5 from a belt conveyer 1 along a guide 6 to the grooves 8 of the rotary conveyer 7 which is arranged in a slightly higher plane than that of the transfer wheel. The grooves 8 are slightly greater than a hemisphere and a raised up portion 12 of the rim extends between each slot to provide a support for the collars of the bottles, so retaining the bottles in place. The bottles in turn couple the two rotary members together, only wheel 3 being driven.
