Abstract: 980,794. Removing metal by electro-erosion. DEUTSCHE EDELSTAHLWERKE A.G., and ALLGEMEINE ELECKTRICITATS - GESELLSCHAFT. Sept. 8, 1961 [Sept.10, 1960], No. 32413/1961. Heading B3V. [Also in Division G3] The adjustment of the sparking gap in electro-erosion grinding apparatus is effected automatically in dependence upon a measurement of an electrical quantity such as spark voltage, number of sparks or the like, representative of the minimum gap width. As shown, a surface grinder 1 comprises a motor 6 and a clutch 7 for advancing a rotating disc electrode 2 towards a workpiece 5 below the level of a working liquid 3 in a tank 4. The engagement of the motor 6 through the clutch 7 is effected by means of a control system including a condenser 17, a resistor 15, a diode 16 and relays 21, 22 and 23. The spark gap between the electrode and the workpiece is supplied from a spark generator 24. At the beginning of a grinding pass switch 18 is momentarily closed so that condenser 17 is charged up to the maximum no-load spark voltage. During the grinding pass the mean spark voltage is applied to the resistor 15 shunted across the gap and condenser 17 discharges over the diode 17 to the minimum voltage appearing across the gap. At the end of the pass a switch 20 is closed for the condenser 17 to discharge through the relays 21 to 23 of graduated sensitivity. The number of relays which pick-up depends on the magnitude of the charge of the condenser 17 and a corresponding advance is provided of the electrode support.

Abstract: 1305848 Fluid-pressure actuated switches GIC Ltd 13 July 1971 [14 July 1970] 32748/71 Heading H1N An electric switch 8, Fig. 5, is operable through a bellows 5 upon squeezing a flexible tube 1 containing a fluid, the bellows 5 being arranged at one end of the tube 1. In examples the tube 1 may be arranged in a flexible mat to operate as an approach detector for automatic doors or, a theft alarm. In the embodiment shown, temperature compensation is provided by mounting a second bellows 5<SP>1</SP> adjacent the first bellows and carrying the switch body 8 on a bracket 7<SP>1</SP>, a leakage passage 15<SP>1</SP> being provided between the bellows 5, 5<SP>1</SP>. In operation, with slow changes of pressure the bellows 5, 5<SP>1</SP> move together but on sudden operation the bellows 5 moves more quickly than the bellows 5<SP>1</SP> whereby the switch actuator 9 is depressed. In a modification the second bellows 5<SP>1</SP> carrying the switch may be coupled to a second flexible tube adjacent to and identical in all respects to the first tube 1 but protected by a rigid shield against squeezing, whereby both bellows move together with temperature changes only. In a further modification the second bellows (5a), Fig. 4, (not shown), may be free and more flexible than the bellows 5 whereby it takes up the major part of the volume change through the leakage path, during slow changes of pressure.

Abstract: 600,345. Drilling &c. machines. SOC. GENEVOISE D'INSTRUMENTS DE PHYSIQUE. Dec. 4, 1945, No. 32798. Convention date, Dec. 22, 1944. [Class 83 (iii)] A telecontrol mechanism for the feed and rotation speeds of drilling, boring, &c. tool spindles comprises a gear-box coupled with an axially displaceable sleeve in which the tool spindle rotates, a second gear-box coupled with the rotary drive means of the spindle, a coupling gear being provided between the driven shaft of the second gear-box and the driving shaft of the first box, sliding gears in the gear-boxes being connected with shifting cams driven by a common intermittent drive with a change-over gear, and interlocking contacting means controlling the driving-motors of the common cam drive and change-over gear. As shown, a drill spindle 2 is driven through bevel gears 4, 5 and fed by a rack 30 and pinion 29 operated from a motor 15 through changespeed gears 7, 14 and 23, 28 respectively, the latter being driven from the former by a shaft 20. Changes in the setting of the changespeed gear 7, 14 are effected by a lever 51 operated by bevel gears 53, 54 from a shaft 55 fitted with a splined gear 56 which may engage a fixed gear 62, or gears 58, 60 on opposite sides thereof, driven in opposite directions by bevel gears 65, 63 from a shaft 66 driven from a second motor 70, the splined gear 56 is raised or lowered by a cam 81 on a shaft 80 driven intermittently by a Maltese cross gear 41, 79 from a third motor 46. The member 42 may be slidden on its shaft by a lever 75 from a cam 73 on the shaft 66 to drive an alternative member 40 which drives a cam 37 operating the second change-speed gear member 28, the motor 15 is started or stopped by switches 17, 18. To change the feed speed the switch 48 is operated to start the motor 46 driving the Maltese cross 40 to move the cam 37 and sliding gear 28. When the index 49 shows the desired speed, the switch is released. For varying the spindle speed, the switch 91 is operated to start the motor 70 to drive the shaft 66 until the gear 42 is shifted to mesh with the Maltese cross 79 when the rotation is stopped by a switch 92-95 which also starts the motor 46 to drive the cam 81 through the Maltese cross 79 and shaft 80. As soon as the desired speed is indicated by the index 90, the switch 91 is released to stop the motor 46 while the motor 70 is reversed to its starting point. A cut-out 100 is provided whereby the spindle 2 and motor 15 may be disconnected to enable the former to be turned by hand for exchanging tools. The cutout is operated by the projection 68 when the shaft 66 has moved the sliding gear 7 to neutral position. Cut-outs 98, 104 effect the disconnection and re-engagement of the spindle.

Abstract: 1,238,527. Dowelling. L. BIAGIONI. 10 July, 1968 [1 Aug., 1967], No. 32847/68. Heading F2H. A gun for inserting adhesive and then a connecting pin 17 into a hole F in a piece of wood P comprises a device fed with pressurized air and including a nozzle 5 for injecting adhesive into the hole and for driving a connecting pin into the hole. In the gun shown, adhesive is fed under pressure via piping 7 to an adhesive collection chamber 8 at one end of the nozzle 5, the nozzle being inserted in the hole F. On depression of a trigger 9 pressurized air flows via a hole 11, the interior of a piston 3 and a hole 15 into a cylinder 60 thus advancing a piston 14. A spindle 13 slidable within the nozzle 5 and forming part of the piston 14 is thus advanced to inject the adhesive into the hole F. After a predetermined time the flow of air is reversed so that pressurized air enters a hole 16, thus causing withdrawal of the spindle 13 and piston 14, cylinder/piston 60 and nozzle 5 secured thereto, and piston 3. Connecting pins 17 fed via a pipe 26 are advanced by a stem 18 of a piston 69 so that the leading pin is placed in front of the end of the withdrawn nozzle 5. The direction of the pressurized air is again reversed so that it enters via a union 2, thus causing advance of the piston 3 and hence nozzle 5 to drive the pin into the hole F.
