Title: A Method and Machine for Regrinding a Cutting Tool
IPC: B23F21/22
Filed: 1966-10-11
Abstract: 1,164,166. Grinding. OERLIKON-BUHRLE HOLDING A.G. 11 Oct., 1966 [13 Oct., 1965] No, 45325/66. Heading B3D. A method of regrinding a cutting tool for the cutting of gear-wheels which tool is provided with a shank 11, a front-cutting face 12 inclined in relation to the axis of the shank, and two relieved flanks 14, 15 and a relieved top face 13 to form a cutting edge is characterized in that the front cutting face is reground, and the relieved face and flanks are ground to such an extent in relation to the amount ground off the front cutting face that the cutting edge is displaced along the shank axis. As described, a plurality of cutting tools are secured in recesses 18 in a cutter head 50 by clamps 17. To grind the cutting tools a machine is described having a cross slide 23 which is mounted on a longitudinal slide 22 and has arms 24, 25 supporting a shaft 26 rotatably adjustable by a wormwheel 29 and hand wheel 30 relative to a vertically adjustable grinding wheel 47. The shaft has a number of pivots 27 supporting holders 28 having guides and clamps 40 for holding the cutting tools 11. The lower ends of the holders are connected by pivots 33 to a member 32, and a worm 38 engages a quadrant 49 on one of the holders for adjusting the holders in unison about their pivots. A stop member 45 can be mounted on the holders for positioning the cutting tools. In carrying out the method, the tools are initially secured in the holders with their top faces 13 perpendicular to the faces 53 of the holders 28 and with their cutting edges abutting the stop member 45. The stop member is then removed and the holders adjusted by the hand wheel 30 until the top faces 13 are parallel to the movement of the slides 22, 23 and the faces are ground by the wheel 47 to remove an amount c. After returning the holders to their initial position, the cutting tools are rotated through 90 degrees in the holders and repositioned by using the stop member. The hand wheel 30 is then used to adjust the holders so that the front cutting faces 12 are parallel to the direction of movement of the slides to permit grinding an amount b from those faces, the cutting edge thereby moving a distance g along the shank of the tool. The holders are then returned to their initial position and the cutting tools again rotated through 90 degrees in the holders and repositioned by abutting the stop member 45, the holders thereafter being adjusted so that the relieved flanks 14 are parallel to the direction of movement of the sliders 22, 23 for an amount a to be ground therefrom, the process being repeated for an amount a to be ground from the flanks 15. A profiled wheel may be used to form a curved top cutting face or to grind the relieved faces in a single pass.

Abstract: 1,127,020. Telescopic support for radiation detector. DAIMLER-BENZ A.G 13 Oot., 1966 [16 Oct., 1965], No. 45821/66. Heading H5R. A telescopic probe for measuring radioactivity comprises a tubular jacket 1 which at its rear end is closed by a cover 3 and has at its front end a securing flange 4, with a plurality of telescopic tubes retractable into the jacket, the innermost tube being provided with a counting tube 8 connected to a recording apparatus. Preferably the innermost tube is provided with a closure plate 10 with a diameter substantially equal to the internal diameter of the jacket at the flanged end thus effectively covering the telescopic system. The plate 10 may have a handle 11 with which the probe may be manually extended. The flanged end of the jacket may also be fitted with a cap 5 which fits over the external diameter of the jacket and is pushed to one side when the probe is erected and replaced as the probe is collapsed. Alternatively a protective covering 6 is employed which cover is projectable with the probe. The probe may be equipped with a spring loaded reel for the cable connecting the detector to the recorder. This reel may be positioned inside the innermost tube as indicated by numeral 9, or may occupy the position 20 shown in dotted line. Preferably the telescopic support is erected and collapsed pneumatically, the necessary compressed air being admitted by knob 19 operating multi-way valve 13 which communicates with pipe 14 admitting air to space 15 to erect the tube and air pipe 16 leading from the valve to space 18 admits air consecutively via conduits 17 to each of the annular spaces surrounding the telescopic sections of the probe as it collapses. As the probe is erected or collapsed, either space 18 or space 15 is connected to the atmosphere via valve 13. Sliding sealing rings 21 on the individual sections maintain an air-tight seal and stops 21<SP>1</SP> co-operate to prevent over-extension. The probe may be arranged on a vehicle (Fig. 2, not shown) for the rapid measurement of a radioactively contaminated area. The plug 12<SP>1</SP> connects the detector via lead 12 to a recording instrument carried inside the vehicle.

Abstract: 1,064,180. Dispensing liquids. WAYNE TANK & PUMP CO. Ltd. Nov. 10, 1965 [Nov. 11, 1964], No. 46031/64. Heading A4T. [Also in Division B8] A liquid fuel dispensing nozzle has a nozzle tube 2 fitted with a tubular plug end 5 formed with diametrically opposed recesses which respectively house a sound transmitter 8 and a sound receiver 9, the arrangement being such that when the nozzle is correctly positioned in the filler tube of a fuel tank the acoustic coupling between the transmitter and receiver is large enough, by virtue of reflection from the filler tube walls, to provide a control signal from the receiver output to operate a solenoid valve 3 in the fuel feed line whereas in open air the signal is insufficient to open this valve 3. A surrounding; protective sleeve 4 is formed with apertures 11 to allow the passage of sound. The nozzle is fitted with a Piezo-electric ceramic element 12 which couples on oscillator and an amplifier such that when the nozzle end and hence the element 12 are immersed in liquid the oscillations of the element are damped and the valve 3 is caused to close thereby to prevent overfilling of the tank. Alternatively, the transmitter 8 may form a part of a bridge circuit forming the level detecting device. Means is provided to prevent opening of the valve 3 when the nozzle is stored in its boot.

Title: Improvements in or relating to Injection Moulding Machines.
Inventor: FISCHBACH ALFRED
IPC: B29C45/67
Filed: 1968-10-01
Abstract: 1,174,390. Injection moulding. A. FISCHBACH. 1 Oct., 1968 [22 Dec., 1967], No. 46613/68. Heading B5A. An injection moulding machine with a fixed mould platen 1, a movable mould platen 5 displaced on rods 3 by hydraulic motors, not shown, to open and close the mould, and means for creating mould sealing pressure, comprises a threaded rod 6 coupled to the movable platen with a locking nut 14, Fig. 1, thereon whereby the nut is rotatable on the rod during displacement of the platen 5 but is locked against rotation after the mould is closed and is urged against a thrust-bearing surface when mould sealing pressure is applied. The nut has a circumferential rib 15 sandwiched between bearings 17a, 17b in a sleeve 16 fixed within a bush 12 threaded to a ring 11 attached to a piston 10. When the platen 5 is moved to close the mould the nut is spaced from the piston 10 .and is allowed to rotate; on mould closure an hydraulic motor is actuated to turn a lever 13 which rotates the bush 12 to bring the nut 14 against the piston 10. Simultaneously a spring 22 forces a non-rotatable member 21 rearwardly so that it engages a tapered portion of the nut to prevent it from further rotation when sealing pressure is applied to the closed mould via the piston 10, the nut 14 and the rod 6. In the embodiment of Fig. 5, the movable platen 5 includes a piston 10<SP>1</SP> which applies the mould sealing pressure, and the threaded rod 6 extends from the piston and carries a rotatable nut 31 within a cup 42 secured to a fixed support 2. On movement of the platen to close the mould a rack 39 attached to the piston effects through gears 38, 35, 33 rotation of the nut so that it is kept a constant distance from the support 2. With the mould closed pressure is applied to the piston to move it slightly rearwardly with respect to the platen 5 to force the nut against the support, after which continued pressurization effects mould sealing. In a modification of Fig. 5, instead of the rack and its associated gearing, the nut is automatically driven on the rod during platen displacement by an electric motor which is arranged either to stop under load or to have a slipping clutch between it and the nut.
