Title: Improved percussion and tamping device
IPC: E02D3/061
Filed: 1961-06-28
Abstract: 934,078. Percussive tools. FICHTEL & SACHS A.G. June 28, 1961 [July 20, 1960], No. 23468/61. Class 124. In a tamping device in which the foot 10 is reciprocated by a motor 20 resiliently mounted on the cylinder 14 of the piston 12 of the foot, accessories such as filters, fuel tanks and carburetters are mounted on the motor so that the lines joining their C.G.'s with their points of fixing approximately coincide with the direction of acceleration of the motor during stamping. The motor is an I.C. engine and the acceleration acts between the line 30 which joins the centre of gravity of the motor with the centre of the foot, and the perpendicular 32 which passes through the centre of gravity of the motor. The motor is mounted on resilient blocks 22 and drives a crank 18 through a flexible coupling to reciprocate the piston.

Title: Improved device for truing profiled grinding wheels for grinding helically toothed involute spur gears
IPC: B24B53/075
Filed: 1959-07-08
Abstract: 891,345. Trueing grinding wheels. ZAHNRADFABRIK FRIEDRICHSHAFEN A.G. July 8, 1959 [July 8, 1958], No. 23503/59. Class 60. A device for trueing profiled grinding wheels for grinding helically-toothed involute spur gears comprises a trueing tool 10 which is guided along the helix on the base-circle cylinder and on the straight generatrix of the helical tooth; during its helical movement the trueing tool is caused to reciprocate in a straight guide rail 12 under the rotating grinding wheel, the rail being adjustably mounted on a supporting body 13 to permit it to be inclined relative to the workpiece axis AB at the helix angle Bg. The device is inserted between centres 25, 26 of the grinding machine, in place of the workpiece, and has imparted to it the same helical movement as the workpiece. The diamond trueing tool 10 is carried in a support 11 which may be traversed along the guide rail 12 by a motor-driven flexible shaft, by hydraulic means, or manually. The guide rail 12 may be pivoted about a screw 16 in a plane parallel to the workpiece axis AB for adjustment of the helix angle Bg and is thereafter secured on bearing faces 14, 15, by the pivot screw 16, and a T-headed screw 17, an angle scale 27 being provided on the face 15. Adjustment of the base-circle radius rg is effected by movement of the support 13 within the guide-pieces 20, 20<SP>1</SP> which are slotted on their inner faces, to take guide ribs 19, 19<SP>1</SP> formed at the vertical end faces of the support, and on their outer faces for engagement by the driver 23, whereby helical motion is transmitted to the trueing-device. Fine adjustment of the device relative to the driver 23 is effected by a screw 24, or alternatively 24<SP>1</SP> when the device is reversed between centres for trueing the opposite flank of the grinding wheel, there being sufficient clearance between the driver 23 and the walls of the slot 22 or 22<SP>1</SP> to permit of slight angular adjustment of the device relative to the drive shaft 25.

G., Ricky, London Road, Dunchurch, both in Rugby. Aug. 29, 1933, No. 23973. [Class 38 (ii)] A coil for a current transformer is wholly or partially surrounded by two overlapping conducting shields insulated from one another and connected to different points on the coil to constitute a condenser connected in parallel with all or part of the coil. A former-wound coil for a current transformer having windings 1 separated by inter-turn insulation 2 is partially surrounded by a conducting shield 3, which may consist of a layer of graphite-treated fabric tape, and is connected to one end of the coil at 9. Suitable packing material is arranged between the shield 3 and the coil 1 to increase the radius of the bends in the shield. A further layer of insulation 5 is applied outside the shield 3 and has a second conducting shield 6 arranged thereon overlapping the shield 3 and connected to the other end of the coil at 10. The main insulation to earth is applied on the outside of the construction thus formed. The conducting shields 3 and 6 act as a condenser shunted across the coil and byepass high frequency transients coming from the line. Also, under normal conditions, these shields are at substantially the same potential as the coil so that any possibility of corona inside the shields is eliminated. According to the Provisional Specification, the conducting shields may be made of metal foil or of insulating tape having a conducting film on one side. Specification 355,675 is referred to.
