Title: Jig for peripheral spraying of small cylindrical components - contg peripherally V-notched parting discs having a profile to permit their removal by tapping
Inventor: MINO HIROSHI
IPC: C23C4/01
Filed: 1972-09-29
Abstract: Several metallic cylindrical components with axial bores are peripherally metal sprayed simultaneously after placing on a shaft alternately with discs made from a similar material and the assembly clamped together. The circumference of the parting discs has a profile which promotes the formation of a weak plane in the sprayed on coating permitting removal of the discs by tapping without endangering the edges of the coating on the workpieces which projects over their edges after removal of the parting discs. This is pref. effected by the parting discs having a symmetrical annular V-notch on their circumference and also a tapered rim inlined between 90 and 170 degrees in relation to the workpiece periphery.

Title: Current generator complementary controllable D.C. - uses slider supplied potentiometer coupled at ends over resistors and PIN diodes to earth
Inventor: AFSAR ERDAL DIPL ING
IPC: G05F3/16

Filed: 1974-04-06
Abstract: A rotary casting machine comprises a heated and/or cooled mould mounted on a revolving plate to rotate about a principal axis in a frame which itself is mounted upon on face of a single vertical wheel rotating about a sec. axis which is oblique, pref. perpendicular, to the first axis; on one side of this single vertical wheel is an integral, pref. hollow, shaft having an additional support bearing some distance from the wheel, the wheel itself running on support rollers. The supporting frame for the ould is a beam or arm eccentrically mounted upon the wheel, so that the mould itself is central to this sec. axis. This supporting beam is rigidly cantilevered from the face of the wheel, so that the mould is freely accessible from the top and from three sides. Pref., the top end of the mould can be clamped by a plate mounted upon a swivelling arm having its pivot axis transverse to the sec. axis of the wheel. This arm and plate can thus be swung away to give access to the top of the mould. The principal rotation is pref. imparted to the mould by a motor mounted on the other side of the supporting arm and driving the plate, to which the mould is fixed, esp. via a bevel gear. The wheel is itself pref. driven by a friction roller directly from a motor. Free access to the mould is obtainable from the top and three sides. The arrangement is compact and ligher than previous arrangements where two wheels are provided to give the sec. rotation, and the frame is larger.

Title: Centrifugal coupling with snap action operating between rotating parts - line of action of spring contact force is near to dead point
Inventor: GRUNDEI MANFRED
IPC: F16D43/18
Filed: 1974-08-06
Abstract: A snap action centrifugal governor operates between a drive motor and an air pump. A vee belt pulley wheel (1) is driven from a motor and carries two pivoted (13) centrifugal weights (3). Two springs (6, 7) force the weights apart and exert contact pressure on a friction pad (4) rigidly fixed to a central sleeve attached to the input shaft of the pump. The line of action of the one spring (6) lies just within the line between the pivot centres. In operation the coupling is engaged until the centrifugal force is sufficient to move the line of action of the spring (6) above the dead point and the coupling disengages with a snap action. When the speed falls the second spring (7) moves the weights until the spring (6) action crosses over the dead point again and the coupling engages with a snap action.
