Patent NL-228610-A (NL)
IPC: B24B49/04
Abstract: 826,904. Grinding. SVENSKA KULLAGERFABRIKEN A. B. June 11, 1958 (June 15, 1957], No. 18622/58. Class 60. An automatic machine for grinding a cylindrical surface on a workpiece having a bevel between the cylindrical surface and an end face perpendicular thereto and comprising a reciprocating gauge arranged to operate a control element to discontinue the grinding operation is characterised by the provision of a pair of co-operating members movable relatively to each other, one of the members being connected to the gauge and the other of the members being arranged to actuate the control element, the relative positions of the cooperating members being determined by the position of contact of the gauge with the bevel, whereby the distance from the position of the gauge at the moment of discontinuation to the junction of the bevel and the cylindrical surface of the finished workpiece will be maintained constant. A race ring 1 of a single-row deep-groove ball bearing with bevels 2, 3 at its ends is mounted in a rotatable chuck 4. The bore is ground by a grinding wheel 33 which, together with its driving motor 29, is carried by a table 28 reciprocated on guides 32. A rod 7 rotatably and axially displaceable in bearings 6 has at one end a gauge 5 and at the other end a block 8 with a groove 9 engaged by pins 10, 11. The pin ] 1 is carried by an arm 13 pivoted to a member 14 connected to the table 28, a spring 16 urges the arm 13 towards a stop 17. The pin 10 is carried by an arm of a friction disc 12 a face of which contacts a friction disc 18 having an arm 19. A cylinder 21 contains a piston 22 the rod 23 of which co-operates with a microswitch 25 pivoted at 26 and adjusted by a screw 27. Before a workpiece is inserted in the chuck 4, the table 28 is moved towards the chuck 4 until a catch 37 on the rod 7 is engaged by a catch 38 to hold the gauge retracted ; this movement brings the arm 19 into contact with a stop 20 and slip takes place between the discs 12, 18. A workpiece is then placed in the chuck 4 and rough grinding proceeds with rapid feed for a predetermined time. At the beginning of finish grinding, with slow feed, a cam (not shown) swings the catch 38 to release the gauge rod 7 ; simultaneously compressed air is admitted to the cylinder 21 to hold the piston 22 in its right-hand position. The spring 16 moves the gauge 5 into contact with the bevel 2; during this movement, the arm 19 abuts the piston rod 23 and thereafter slip takes place between the discs 12, 18. The air pressure on the piston 22 is released, and finish grinding proceeds until the diameter of the workpiece has the required value whereupon the gauge enters the base sufficiently to cause the piston rod 23 to actuate the microswitch 25 and discontinue grinding. The friction discs 12, 18 may be replaced by a a piston and cylinder or other device having two members relatively movable with friction. External cylindrical surfaces may be ground.

A mine roof support has a hydraulic roof support member 2 and a horizontal advancing ram 1, a control valve 6 actuated by pressure acting on the ram 1 from a supply 3 to lower the member 2 by allowing fluid to escape from it to a return line 4, and a second control valve 8 actuated at a predetermined positional setting of the ram, e.g. by an abutment 18 on the ram engaging the valve, to over-ride the valve 6 to raise the member 2. The operation is started by opening a valve 5, and fluid-pressure then opens the valve 6, and advances the ram 1. When the valve 8 is opened, the pressure is transmitted along a line 9 to close the valve 6, and through a non-return valve 11 to raise the member 2. The valve 8 and abutment 18 may be replaced by an opening in the ram cylinder, connected to the lines 9 and 12 and uncovered by the piston near the end of its stroke. The valve 5 may be opened by fluid-pressure, e.g. from the line 9 of an adjacent unit, the units then operating sequentially Fig. 2 (not shown). In another embodiment Fig. 3 (not shown) the line 9 leads through a two-way fluid-pressure operated valve to the valves 5 of an adjacent unit on each side and the units are operable sequentially either from left or right or right to left. Reference has been directed by the Comptroller to Specification 967,164.

Patent NL-8203828-A (NL)
IPC: B01F23/57
Filed: 1982-09-30
Abstract: Functional agglomerated speckles, for incorporation in dentifrices, include agglomerates of a water insoluble powdered functional material and water insoluble, ethanol soluble ethyl cellulose, and may sometimes preferably also include a water soluble binder, such as polyvinyl pyrrolidone. Such speckles satisfactorily maintain their integrity and identity during processing of the dentifrice after addition of the speckles to a main dentifrice body but on storage, after packaging of the dentifrice in dispensing tubes, soften sufficiently so as to become essentially impalpable to one utilizing the dentifrice in brushing his teeth. Despite such softening the speckles continue to maintain their identity as speckles in the dentifrice. The speckles are especially useful in translucent or transparent gel dentifrices which contain components, such as flavouring and surface active agents, which may controllably soften the speckles on storage.
