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.

Abstract: 1,052,148. Valves. FRANK XAVER BAUMEISTER G.m.b.H. and H. DUNTZE. March 1, 1965 [Feb. 28, 1964], No. 8708/85; Heading F2V.  A thermostat 1 expands with rising temperature and through a spindle 6, nut 7, sleeve 8, and spring 25 lifts a plate 24 slidable on the sleeve 8 and so rotates a lever 22 to close a valve 21 on to a rubber seat; any further expansion of the thermostat cannot move the lever further so the spring 25 yields and serves as a safety device. The operating temperature is adjusted by altering the compression of the spring 25 via a knob 27, spindle 6 and nut 7. The lower thermostat closure 4 sits on a casing plug 5.  Should the thermostat become defective due to loss of fluid a valve spring 20 will act through the lever to urge a lower flange 29 on the sleeve 8 against the plug 5. If the knob 27 is then rotated until a shoulder 28 therein abuts a guide 9 then further rotation of the knob causes upward displacement of the nut 7 and sleeve 8, and the spring 25 lifts the plate 24 to rock the lever in the valve closing direction. The thermostat is readily replaced upon removing the plug 5.  A sealing bellows 19 is disposed around the valve stem 18.
