Title: A speed control and programming system
IPC: B23D36/00
Filed: 1963-06-28
Abstract: 992,188. Programmed control of position. MIEHLE-GOSS-DEXTER Inc. June 28, 1963 [July 6, 1962], No. 25825/63. Heading G3N. A programming system for controlling the movement of the back gauge of a guillotine type paper cutter comprises a magnetic tape which travels with the back gauge and upon which sequential signals are recorded. Each signal effects deceleration of the gauge when it passes a first head, and subsequently reaches a second head to stop the gauge whereupon a cut is made by a descending knife. Each slow-head signal is fed into a store, and each such signal is normally cancelled when the corresponding cut is made as the signal passes the stop-head. After a cut is made, the gauge is reversed at high speed unless the recorded signals follow each other closely so that an uncancelled signal is retained in the store, the gauge then being reversed at low speed. Initially, clutch solenoid 105 is energized for low-speed operation of the gauge, and, at the end of a period determined by time delay relay CR5, clutch solenoid 110 is energized for moving the gauge at high speed. When a signal reaches head 10, the gauge is returned to the low-speed condition, and solenoid 82 is energized to store the signal and open contacts 55 in series with high-speed relay CR4. When the signal reaches head 8, the gauge is stopped. A solenoid 67 is not energized to remove a stored signal unless the delay period of relay CR5 has expired so that the gauge is reversed at low speed when the recorded signals follow each other closely. Indefinite slow running is prevented by time delay relay CR 25 adapted to energize solenoid 91 and remove all signals from the store. The storage device comprises a differential gear having a planet wheel biased to a central position and adapted to operate a cam for opening contacts 55. The planet wheel co-operates with a pinion stepped by a double pawl actuated by solenoid 67. Another pinion is actuated by solenoid 82, whilst solenoid 91 is adapted to bring the planet wheel back to the central position. The solenoid 82, when energized, tends to separate contacts 55, whilst solenoid 67 reverses the planet gear and permits the contacts to approach one another.

Title: Improvements in and relating to a device for enlarging the bottom of a bored hole
IPC: E21B11/04
Filed: 1961-07-20
Abstract: 924,237. Boring earth &c. P.J.M.T. ALLARD. July 20, 1961 [July 26, 1960], No. 26298/61. Class 85. [Also in Group XXIX] An under-reamer comprises a body 1 adapted to be lowered into a borehole, means 3 on the body adapted to be pressed into engagement with the wall of the borehole to prevent rotation of the body, and means 6, 13, 14 to rotate the cutting tools 18 relative to the body. When the under-reamer is positioned in the borehole with the tools below a boring tube T an electric motor 7 is started to cause a pump 9 to supply hydraulic fluid to the system controlling the tools and the wall engaging means. The fluid passes through a valve 44 to cylinders 4 to urge the pads 3 into engagement with the wall. When the pressure in the cylinders exceeds a predetermined amount the fluid flows through valve 48 to drive the hydraulic motor 6 to rotate the tools. Fluid from the motor 6 passes through pipes 58, 59 to the upper end of a cylinder 5 to commence to open the tools. When the pressure in the cylinder 5 exceeds a given amount a valve 60 opens to discharge fluid to a reservoir 10. As the cutting resistance decreases the fall in pressure in the cylinder 5 permits the valve 60 to close and the tools to open further. If the pressure on the motor 6 becomes excessive a valve 50 opens so that a valve member 52b is moved to the left to discharge fluid from the upper part of the cylinder 5 through pipe 55 and to feed fluid from pipe 51 to the lower part of the cylinder 5 by the pipe 56 so that the tools commence to close until the pressure on the motor 6 falls sufficiently. When, during normal operation, the tools reach the fully-open position a switch 64 is operated to move the valve member 52b and open a valve 61 so that the tools start to close. When the tools are finally closed, a switch 66 is operated to set the valve 44 to retract the pads 3 from the wall, and the under-reamer is withdrawn from the hole. The tools may be used as a grab to remove the soil loosened during reaming.

IPC: F16H37/08
Filed: 1920-09-14
Abstract: 151,013. Waldenmaier, W. Sept. 15, 1919, [Convention date.]. Void [Published under Sect. 91 of the Act]. Variable-speed gearing comprises an epicyclic train controlled by disk-and-roller and worm gearing. A wheel 3 secured to a driving-shaft 2 has bevel-teeth driving an idle disk 4, and internal spur teeth meshing with planetary gears 27. The gears 27, which are carried by a disk 29 secured to a sleeve 21, mesh also with a sun gear 26 fast upon a driven shaft 22. An idle wormwheel 19 meshes with a worm 20 fast on the sleeve 21, and with a worm 17 slidable on a parallel shaft 8. The shaft 8 carries a friction clutch member 16 and a feathered friction gear 7, which slides in contact with the disk 4. In action, when the gear 7 is near the centre of the disk 4, the worm and disk 29 are stationary, the worm 17 being thrust into engagement with the clutch 16. The gear 26 and shaft 22 are driven reversely at top speed. As the gear 7 is moved to the right, the worm gearing moves, allowing the disk 29 to turn, so that the shaft 22 slows down. If the disk 29 turns too fast, the wheel 19 causes the worm 17 to move out of engagement with the clutch 16, allowing the gear 7 to roll without slipping. The gear 7 is controlled by a hand crank 15.
