Title: Improvements in or relating to the dressing of grinding wheels
IPC: B24B49/18
Filed: 1964-12-16
Abstract: 1,088,027. Trueing grinding wheels. NEWALL ENGINEERING CO. Ltd., and W. K. TEMPLE. Dec. 15, 1965 [Dec. 16, 1964], No. 51155/64. Heading B3D. A grinding machine comprises a grinding wheel 10 mounted on a support 12, a dressing tool 45 operable to dress the grinding wheel, and automatic means responsive to the condition of the grinding surface of the wheel for controlling the operation of the dressing tool when the grinding surface deteriorates to a predetermined condition, said automatic means being governed, in providing its response to the condition of the grinding surface, by a factor based on other than time in use of the wheel. The condition sensed may be frequency or amplitude of vibration of the grinding wheel, rise in temperature of the wheel or work, compression force between the wheel and work change of profile produced on the workpiece the change in power necessary to drive the grinding wheel or workpiece, or the change in hardness of the workpieces resulting from the heat generated during grinding. The grinding wheel 10 is carried by a support member 12 having guide ribs 13 engaging guideways on a base 14 for movement towards and from a workpiece support 16 movable along guideways 14. The support member 12 has a depending lug 17 formed with a hole receiving the end 18a of a feed screw 18 having a shoulder engaged by a spring 20 which urges the lug against a nut 19 on the end of the feed screw. The feed screw is held against rotation by a key in the hole in lug 17 and engages a nut 22 which is rotatably mounted in a sleeve 28 and has a gear-wheel 23 slidably meshing with a gear 24 on a feed shaft 25 provided with a gear 26 for transmitting rotation from a pinion and hand wheel. The sleeve 28 is slidably keyed to a boss 29 and is formed with a housing 31 containing a thrust bearing 32 for transmitting thrust from the housing to the nut 22 and feed screw 18 when the housing is moved by the rod 37 of an hydraulic motor to effect rapid feed of the grinding wheel. The support member also carries a compound slide 46 for a diamond-tipped dressing tool 45 controlled by a mechanism 47 connected to a micro-switch 40 which is mounted on the lug 17 and has a finger 41 normally spaced from an operating member 42. During grinding with a freshly dressed grinding wheel which is movable relative to the bed rapidly by axial movement of the sleeve 28 and for normal feed by a handwheel or motor rotating the nut 22, the force between the wheel and feed screw is insufficient to overcome the spring 20 so that the member 42 remains spaced from the finger 41. As the wheel wears, the force increases to overcome the spring so that member 42 actuates the micro-switch to initiate a dressing operation. In other embodiments, the mechanism 47 is controlled by one of the conditions referred to above.

Abstract: 1482558 Stop-watches SOC SUISSE POUR L'INDUSTRIE HORLOGERE MANAGEMENT SERVIES SA 5 Dec 1974 [7 Dec 1973]  52700/74 Heading G3T. In order to permit several different stop-watch movements to use at least some parts in common, such a movement comprises a flirt 3 for stopping and freeing a balance in the movement train, a navette 5 for actuating return-to-zero hammer 6, a control member 2 having a pin 32 which can slide in a slot 33 in frame plate 1 when a pushpiece (not shown) is depressed, and a spring 9 which returns the member 2 to its rest position, as shown, when the push-piece is released and which is arranged, in that position, to act on the member alongside the line of sliding of the pin 32 so as to put a torque on the control member and press a finger 41 thereon against at least one of the parts 3, 5. In the movement shown the push-piece is actuated successively for the start, stop, and zero operations, the requisite motions of the parts being produced by a reverser 7 and a forked jumper 8, the two arms of which co-operate with a pin 30 on the flirt 3 and a pin 31 on the navette 5. The mechanism is shownin the RUN position, a pin 37 on the reverser being pressed against shoulder 2a of the member 2 by the spring 9. At the next operation of the push-piece, the finger 41 causes the flirt to turn clockwise about its pivot 10 to stop the balance, Fig. 3 (not shown), and the finger then passes to notch 5b of the navette. A further operation of the, push-piece thus turns the navette about its pivot 11, actuating the hammer 6, Fig. 1 (not shown), and the finger is returned to a notch (3a) of the flirt as the member 2 is turned clockwise about pin 32 by the reverser. A pin 12 on the navette co-operates with a brake lever (not shown) to brake the fourth wheel when the hammer is in its zeroing position. In an alternative movement, the reverser 7 and jumper 8 are omitted and a separate push-piece and slider (46), Figs. 4, 5 (not shown) are used for resetting to zero, thus permitting restarting without zeroing. As a further alternative the member 2 may be used for zeroing only, with a separate push-pull plate (57), Figs. 6, 7 (not shown) to start and stop the balance.

Abstract: 1483806 Automatic exchange systems SIEMENS AG 6 Dec 1974 [20 Dec 1973] 52767/74 Heading H4K An arrangement including a counter for counting ringing tone bursts is provided in order to call a number of subscriber stations sequentially. The Figure shows an arrangement for controlling the ringing of two subsets. A counter comprising three bi-stable circuits ZK is provided which counts ringing signal bursts and the counter is coupled to gates G4 and G15 in such a manner that gate G4 receives an enabling signal on wire 6 whilst the counter is counting from 0 to 3 and gate G15 receives an enabling signal from gate G14 whilst the counter counts from 4 to 7, the process repeating for as long as the ringing signal persists to open and close contact 1ar. By means of the gates G4, G15, line switches AK1, AK2 are operated during the respective count ranges of counter ZK to cause calling signals to be supplied during alternate periods, of 4 ringing signal bursts to the pair of subsets. When the call is answered at a subset while it is being called, e.g. subset H, a circuit RS3, enabled during the subset's ringing period via gate G8, is switched by an input on wire 12 to hold the line switch AK1 via gate G4. Simultaneously switch 25 is closed and a binary 0 present on wire AU during the whole ringing operation is charged to 1 to reset the counter ZK. If a subset is busy when the exchange line provides ringing current, a respective switch 2S, 3S is closed to prevent an enabling signal being supplied to the respective one of circuits RS3, RS4. However the calling signal is still supplied to the busy subset. The arrangement can be modified to sequentially ring a greater number of subsets cyclically until one answers. The circuitry may be in monolithic integrated module form.

Abstract: 1485298 Ink ribbon mechanisms OLIVETTI & C Spa ING C 6 Dec 1974 [28 Dec 1973] 52860/74 Heading B6F An ink ribbon 15 is fed from a feed spool 20 to a take-up spool 21 via ribbon tightening lever 50 which forms a loop 48, the arrangement including a sequencing device which causes ribbon to be fed alternatively from the feed spool to the loop former with take-up spool stationary and from the loop former to the take-up spool with the feed spool stationary. As shown, the feed spool 20 and the take-up spool 21 are connected to electric motors 27, 29 respectively through reduction gears which will transmit torque from the motor to the corresponding spool but not vice versa. The lever 50 is keyed to a pin 51 which also carries a cam 65. Levers 71, 72 pivoted at 75 and lever 73 pivoted at 76 are provided with lugs 77, 74, 79 respectively which are urged against the cam profile by springs 80, 81. Levers 36, 37 abut the ribbon wound on to the corresponding spools. When the motor 27 is energized to allow feed of ribbon from the spool 20 the lever 50 is urged clockwise by a spring 60 to form the loop and simultaneously rotate the cam so that after an appropriate rotation of the latter the levers 71-73 actuate microswitches 30, 78, 31 which stop the motor 27 and start the motor 29 so that ribbon is wound from the loop to the spool 21. The consequent anti-clockwise rotation of the lever 50 resets the mechanism to start the motor 27 and stop the motor 29. The levers 36, 37 co-operate with microswitches to reverse the motors when the appropriate spool is full. The microswitches control the motors through flip-flops and NAND gates.
