Edge-runners and pans and like mills.- Relates to rollers for mortar, grinding, and other similar mills of the type provided with renewable outer ring or tread held on a central or main body portion by suitable wedge devices located between the ring and the body and driven or forced in from either or both sides of the roller. The central or main body portion of the roller is formed with recesses on its outer surface in which the wedges are located. Key-pieces may be located between the wedges and the ring tread. As shown in Fig. 2, the central body portion 12 has in its outer cylindrical surface a number of recesses or grooves 13 of rectangular channel section extending parallel to the axis and arranged at equal distances apart, the side walls of the channel being stepped towards the ends to leave a wide central channel with two narrow ends. A key 15 of rectangular section is placed in each groove 13, the ends of the key being stepped at 16, 17 so that the ends are narrower both radially and circumferentially than the central portion between the steps. The ring 18 is formed on the inside with a shallow annular channel 19 having a width equal to or slightly greater than the distance between the steps 16 on the keys 15. Wedges 20 are driven into the spaces between the bottoms of the recesses 13 and the inner faces of the keys 15. One wedge is driven in each channel from each side of the body 12 so that the bevelled surfaces of the two wedges come together. The ends of the wedges may be caulked in, V-grooves 21 being formed in the surfaces of the ends of the recesses 13. In a modification, Fig. 5, a single wedge 22 with a bevelled upper surface co-operates with a key 15 having a bevelled under surface, successive wedges being driven in alternately from opposite sides of the roller. In another modification, Fig. 8, wedgebolts 23, of rectangular section are used, the bevelled surface of each bolt engaging in a channel 13 with a bevelled bottom 25 in the body 12 and a flat face 26 engaging the inner surface of the ring 18. The screwed end 27 of each bolt is received in a circular recess formed partly in the body adjacent the end of the channel and partly in the end surface of the ring 18. The wedges and bevels of successive channels are oppositely directed. Figs. 110 and 11 show the body 12 of a roller having grooves or recesses in its outer surface with bevelled bottoms 29, the bevel from one side being oppositely inclined to that from the other side and coming near to or at the peripheral surface of the body at its central position.

Abstract: 955,260. Liquid applicators. I.R.C. Ltd. July 11, 1961 [July 30, 1960], No. 26623/60. Heading A5R. [Also in Divisions B2 and B6] A reservoir for applying scent, deodorants and other cosmetics is of the kind having a sealing means for a vented bore occupied by a liquid column, the sealing means including a solid follower at the rear end of the column, the follower being an easy sliding fit in the bore so as to move along it as the liquid is discharged. As shown, a ball-point reservoir 10, Fig. 2, of non-capillary size has a follower 12 slidable in the bore, the annular clearance around the follower being occupied by sealing liquid which may be the liquid 11 contained in the reservoir or another liquid. A ball 21 of heavy material, e.g. metal, compresses a spring 20 when the pen is held in the Fig. 2 position. When the reservoir is horizontal, Fig. 4 (not shown), the ball has no effect on the follower, however, when the reservoir is inverted, Fig. 3, the follower 12 is engaged by the ball, the thrust of the spring 20 and ball 21 is insufficient to eject the follower but exerts a force on the follower which is sufficiently high to prevent seepage past the follower. According to the Provisional Specification, the follower may consist of front and rear sections equipped with permanent magnets which draw the sections together, the construction being generally similar to that described in Specification 932,203.

Abstract: 1391206 Concentric duct rotary heat exchangers; refrigerating PHILIPS GLOEILAMPENFABKIEKEN NV 9 June 1972 [14 June 1971] 27073/72 Headings F4S and F4H [Also in Division F1] A pumping device comprises a rotor 1 wherein a gas is conducted away from the axis of rotation through a compression duct 4 in which the gas is compressed by centrifugal force and the heat of compression withdrawn, the gas then flowing through a communication duct 5 to an expansion duct 6 through which it flows towards the axis against the centrifugal force and in which heat is supplied to the gas before exhausting through outlet duct 3 in heat exchange with duct 5. The heat supply is such that the gas temperature in expansion duct 6 is always higher than that in compression duct 4 so that as a result of pressure differentials and centrifugal action gas is pumped through the rotor. In the arrangement shown rotor 1 is supported on gas bearings in blocks 22, 23. Heating of expansion duct 6 is by burners 8 or electric coils whilst cooling of compression duet 4 is by gas or liquid circulating through coils 7 and in heat exchange with duct 4 via the bearing gas of block 22. The body of rotor 1 constitutes a heat exchanger for transfer of heat from central outlet duct 3 to communication duct 5 and is formed by a series of circular foils 9a of heat conducting material, e.g. copper or aluminium, spaced apart by annular heat insulating members 9b. The foils 9a are provided with ports (24, 25, Fig. 3b, not shown) at the centre and periphery respectively to define ducts 3, 5. Heat exchanger 9 may alternatively be constructed of wire or ribbon gauge. Radial and axial partitions (20, 21) may be provided in the ducts. In Fig. 6 (not shown) the pumping device is connected to a cold producing device (B) such that the gas from outlet 3 flows through an expansion valve (61) on the axis of rotation and into a cold chamber (64) for external cooling purposes. The gas then flows through a heat exchanger (63) to precool the gas entering expansion valve (61) and thence returns to the pump inlet 2. The working gas may be neon, argon, nitrogen, crypton, hydrogen, helium or the isoptope He<SP>3</SP>. Air or liquid nitrogen cooling of compression duct 4 may be used. The cold producing device (B) may rotate with rotor 1 of the pump or be stationary, in the latter case magnetic liquid seals being provided in the gaps between the rotating and stationary parts. In further modifications (Figs. 4a, 5a, 5b, not shown) the ducts 3 to 6 of the pump are arranged to give a number of passes through rotor 1 to thus constitute a multi-stage assembly.
