Title: Methods of and apparatus for grinding mineral material

IPC: B02C17/04
Filed: 1968-01-16
Abstract: 1,248,251. Tube mills. F. L. SMIDTH & CO. A.S. 9 Jan., 1969 [16 Jan., 1968; 28 March, 1968], Nos. 2366/68 and 15006/68. Heading B2A. A tube mill comprises a grinding compartment or compartments 5, Fig. 1, and a short or intermediate compartment 6 downstream of the first or sole grinding compartment to serve as a reservoir for ground material which is fluidized by the ventilating air drawn through the mill. The partition 8 between the compartments 5 and 6 enables the fluidized material to flow from either compartment to the other. The downstream end of the compartment 6 has a wall 9 with an opening 14 (or openings) through which the ground material can pass, located so that a pool of fluidized ground material always exists in the compartment 6. The reservoir of material in the compartment 6 inhibits passage of material through the mill except at the rate at which it passes through the wall 9. Thus the grinding compartment 5 is permanently overfilled. Consequently noise, and wear of the mill lining are reduced. Partitions may have larger openings permitting easy airflow, and scoops 13 carried by vanes 22, Fig. 5, may be used in the intermediate compartment to facilitate control over the lever of the fluidized material. In a further embodiment, a pair of rings 30, 32 Fig. 7, surround solid central portion 27 and shroud an opening 31 in a partition 25 so that material flows down the surface of the fluidized pool while the opening remains shrouded. The mill may be controlled by a known microphone, transmitter and amplifier arrangement.

Abstract: 612,347. Tipplers; winding and paying-out apparatus. STRACHAN & HENSHAW, Ltd., and GROSSMITH, G. W. May 17, 1946, No. 15050. [Classes 78 (ii), 78 (iv) and 78 (v)] A wagon-tilting apparatus comprises a cradle incorporating a platform for the wagon, the cradle being supported at three points in spaced relation, one supporting point being fixed in space and having the cradle connected thereto by a universal joint, the other two supporting points being movable. As shown in Fig. 1, the cradle A and the support D have a ball-and-socket connection at 5. Cables 36, 37, Fig. 2, wound upon winches 38, 39 are attached to the brackets 40 on the underside of the cradle. To tilt the wagon laterally, the cables 36, 37 are hauled in by the winches 38, 39. Longitudinal tilting is commenced when the three points of suspension have been brought into the same horizontal plane by hauling on one cable and releasing the other. A rail table B is suspended by links 10 so that it may move transversely upon tilting of the cradle to enable the supports 7 to engage the sides of the wagon C. Buffer clamping members 48, Figs. 2, 6, each comprising a spring- actuated plunger 49 and rollers 50 are movable by an electrically-driven screw-and-nut mechanism 43, 42 along guides 41 towards the buffers of the wagon to secure it during longitudinal tilting, or towards the curved ends of the guides to swing clear of the path of the wagon. A limit switch carried by each buffer engaging member 48 is operated by the plunger at a predetermined point in its compression stroke to disconnect the electric motor from its supply. A brake held disengaged by a solenoid connected in parallel to the motor circuit is applied to the motor upon interruption of its supply.

Title: A method and means for shaping and trimming helically formed grinding wheels

Filed: 1954-05-24
Abstract: 764,707. Truing grinding wheels. WICKMAN, Ltd. May 11, 1955 [May 24, 1954], No. 15184/54. Class 60 A peripheral helix is generated on a grinding wheel i by a rotory cutting tool u resembling a toothed wheel, the contour of the teeth of which is conjugate to that of the form to be imparted to the grinding wheel. The grinding wheel i and control wheel m formed with a peripheral helix corresponding to that to be formed on the grinding wheel are mounted on parallel axes on a pivotally-mounted arm c and driven at the same speed by a motor d through gearing e, f, g. The cutting tool u is mounted at one end of a spindle r which at the other end carries in mesh with the control wheel m a toothed wheel t similar to the cutting tool; the spindle r is mounted in a bearing q on a compound slide o, p disposed beneath the arm c. The arm c is adjustable about its pivotal axis (which is the axis of the control wheel m) by stops h so as correctly to position the grinding wheel in relation to the tool. After lowering the cam c so as to bring the grinding wheel to its full depth position, the slide p is moved to the right until its operative end face occupies the vertical plane containing the axis of the grinding wheel, and during this movement the slide o is moved in a direction parallel to this axis to cause the tool to travel across the grinding wheel. The axis of the spindle r may be inclined so as to be substantially parallel to the helix to be formed on the grinding wheel, and the slide p is then arranged to move substantially parallel to this helix. If desired, the cutting tool may be first moved until its operative end face occupies the vertical plane containing the axis of the grinding wheel and the latter is then moved downwards to the full depth of the helix during the rotational and traverse movements above described. Either a single helix or multistart helices may be formed on the grinding wheel and the operation may be used both for restoring a previously formed helix to its initial condition and forming a new helix in a plain cylindrical grinding wheel.

[Class 138 (i)] A windscreen wiper of the kind in which a rotary blade 18 is carried by a movable arm 10 which carries the blade to a parked position by a rotary or other movement, is constructed with anti-friction means such as rollers 32, Fig. 2, which engage an abutment member 26, when the arm 10 is being moved to its parked position, so that the blade 18 is forced to a position in which it does not obstruct the view. The abutment 26 is fixed at the side of the screen 24, and the rollers 34 are mounted in U-shaped clips 36 riveted to a metal bead 40 of the wiper. The arm 10 can be moved by a lever 46 on a shaft 44 provided with a second lever 48 for switching off the driving current when the wiper is parked. The rollers 32 may be mounted so as to be closer to the shaft 16 of the blade, and they may be replaced by curved springs. The abutment 26 may be formed with a sharpened blade-like portion 54, Fig. 4 (not shown), or may be formed as a guide 60, Fig. 5, fitted at its centre with a roller 62 and formed with a flange 64 for securing it to the frame 32.

In the construction shown, a strip of material 30, in conjunction with metal blanks, each bent round a core, is formed by devices 11, 12 into a succession of mop frames. A frame 10 is provided with uprights 21, 22, supporting guides 20 capable of being rocked by means of levers 23, 26 and a rod 24 having a roller engaged by a cam 25.

Stops 31 and stop latches 34 are provided along the path of the mop material. As the bars 27 move forwardly a mop frame is moved from the stops 31 to the latches 34, and a second mop frame is moved from the latches 34 to a position of discharge c.
