Title: Curved surface generator
IPC: B24B19/09
Filed: 1972-07-21
Abstract: 1377150 Generating surfaces GLEASON WORKS 21 July 1972 [15 Sept 1971] 34247/72 Headings B3D and B3K Apparatus, e.g. for generating epitrochoidal bores for rotary I.C. engines comprises a frame 71, and eccentric means 68, supported by the frame 71 for rotation about an axis 25, and having bearing means 66 supporting means 64 for mounting a workpiece W for rotation about an axis 23 parallel to and adjustably spaced from the axis 25. Tool support means may support a grinding wheel T or milling cutter (not shown), to define a machining line M parallel to the axes 23, 25, the tool support means being mounted for oscillation about an axis coincident with the machining line M. Means is provided for rotating the eccentric means 68 and work support means 64 and oscillating the toolsupport means in timed relationship. The workpiece W may be secured to a work-table 62 on the support shaft 64, the bearing 66 being adjustable on slides 74 of the eccentric means 68, Figs. 4, 5, which is in the form of a drum, for positioning its axis 23 relative to the axis 25. For orbiting the workpiece W about the axis 25, the drum 68 is driven by a motor 76 acting through gears 78, 80, a shaft 82, gears 94, 96, a worm 90 and a worm-wheel 92, the shaft 64 being driven through a further worm 84 and worm-wheel 86 acting through an Oldham coupling 100-112. The grinding wheel T is supported on a spindle 134 driven through a belt 140 by a motor 138, the spindle 134 being borne by a slide 120 adjustable by screw means 158 on a support 116, oscillatable about an axis coinciding with the machining line M so that the periphery of the wheel T, defining the line M, may maintain tangency with the workpiece W. The support 116 is oscillated by crank means 58 having a pin 56 engaging a slot 54, a spindle 128 of the crank means 58 being driven by the shaft 82 through a worm 130 and wormwheel 132. To maintain a constant linear relative speed between the wheel T and the workpiece surface, a cam 162 on the spindle 128 is arranged to act on a control lever 166 of rheostat means 168 for governing the speed of the motor 76. For dressing the grinding wheel T, a diamond wheel 148 is provided, and a face cam 144 driven by a motor 142 acts against a roller 146 to reciprocate a spindle support quill 136 relative to the workpiece W.

Class 60 Apparatus for dressing a helically ribbed grinding wheel 4 by an annularly ribbed freely rotatable crushing roller 3 includes a toothed rack 20 arranged to act upon a sliding head 2 for the roller 3 and a toothed rotary member 19 co-operating with the rack whereby the latter is only driven for an operative axial traverse of the roller whilst return movement of the head 2 is permitted thereafter, the member 19 being connected for operation in timed relationship with mechanism for effecting relative movement apart of the wheel 4 and the roller 3. The wheel 4 is rotatably mounted on a slide 7 and its shaft 5 drives the member 19 through a slidably splined worm drive 13, 14, a shaft 15, gearing 12, a shaft 16 and a worm drive 17. The shaft 16 is extended to drive a cam 22 having a slot 25 to impart an intermittent reciprocating motion to a slide 27 having a cam groove 29 which reciprocates the slide 7 through a lever (not shown) connected to a lead screw 10. When the roller 3 has completed an operative transverse across the wheel 4, the latter is separated from the roller 3 by the cam 22 and the head 2 restored to starting position by a weight 21 operating in a dashpot before the wheel and rollers are again brought into engagement. The member 19 may be replaced by a. pinion which is clutch driven or adapted to move axially so as to free the head 2 for its return movement.

Abstract: 1,013,913. Electromagnetic relays. STANDARD TELEPHONES & CABLES Ltd. Sept. 14, 1962 [Sept. 21, 1961], No. 35186/62. Heading H2B. The air gap between the reeds of a sealed magnetic contact device is adjusted after sealing one reed in position by rotating the other reed prior to sealing it in position. Reeds 2, 2<SP>1</SP> mounted in magnetic holding devices 1, 1<SP>1</SP> and a glass tube 3 mounted in a holding device 1<SP>11</SP> are moved into alignment with heaters 10, 11, an adjusting winding 12 and rotatable clamps 5 and 6. The reeds 2, 2<SP>1</SP> are gripped by the clamps 5, 6 respectively and the tube by a clamp 13 before the holding devices 1, 1<SP>1</SP> and 1<SP>11</SP> are removed. The clamps 5, 6 are rotated about axes 17, 17<SP>1</SP> respectively until the reeds 2, 2<SP>1</SP> engage contacts 15, 16 which are connected in control circuits for the clamps 5 and 6. The contacts 15, 16 ensure that the inner ends of the reeds are exactly parallel. The contacts 15, 16 are withdrawn and the tube 3, adjusting coil 12 and heaters 10 and 11 are lowered over reed 2<SP>1</SP>. The reed 2 is then lowered into the tube. Air is driven out of the tube 3 by a continuous stream of inert gas which enters by way of a capsule 7 enclosing the clamp 6. The upper heater 10 is switched on and the adjusting coil 12 energized so that the reeds engage. When the reed 2 is sealed in position the heater 10 is switched off and the clamp 5 removed. The lower heater 11 is switched on to pre-melt the lower end of the tubes and the winding 12 is de-energized when the upper seal has hardened. Clamp 6 is rotated to cause disengagement of the reeds and the tube 3 and upper reed 2<SP>1</SP> are moved horizontally so that the sealing point 17<SP>1</SP> of reed 2 is in the centre of the tube. A sensing probe 18 is connected to reed 2 in a circuit comprising reed 2, the probe, a power source, a relay, lamp 6, and reed 2<SP>1</SP>. The winding 12 is energized, heater 11 switched off and clamp 6 rotated until reeds 2, 2<SP>1</SP> engage. The winding 12 is now deenergized and the heater 11 is switched on to complete the lower seal. The above adjustment can be performed mechanically by rotating the clamp 6 until the reeds engage with winding 12, de-energized and then displacing the reeds mechanically.

Abstract: 1,110,067. Logic signals. WESTING- HOUSE ELECTRIC CORPORATION. 8 Aug., 1966 [9 Aug., 1965], No. 35346/66. Heading H3T. A logic circuit has a transistor of complementary type in series with the output transistor and fed from the input to the latter via a differentiating circuit, to provide a pulse of current to charge any capacitance in the load and thus ensure high fan-out possibilities with low power dissipation. Fig. 3 shows a NAND circuit with inputs via diodes 57, 58 to an output transistor 64 having a capacitive load shown at 67. If one or both of the inputs drops to a " 0 " level the voltage at 62 will fall, cutting off transistor 64 and providing a " 1 " at the output. The change in voltage at 62 is passed via differentiating capacitor 84 to the auxiliary transistor 77 to turn it on for a short time, allowing current to flow from terminal 79 to the load 67 to charge up the capacitance rapidly. The output voltage remains at " 1 " for an extended period of time depending on the timeconstant of the load. Transistor 72 forms a cross-coupled pair with transistor 64 to speed up switching as in Specification 1,110,066. In a modification (Fig. 4, not shown) transistor 77 is replaced by a complementary pair to give a higher current gain. These may be in integrated form as in Specification 1,023,565. Transistor 72 is also replaced by a similar complementary pair, the second one of these replacing the diode 69. A speed-up capacitor (88) is joined between point 62 and the base of 64. Resistor 81 is split into two parts, the junction being clamped by a diode (96) and the emitter of 72 is decoupled by a capacitor (99) to eliminate A.C. transients. The complete circuit may be made in integrated form. A NOT circuit is also described (Fig. 2, not shown).
