Title: Improvements relating to drilling
IPC: E21B21/08
Filed: 1961-07-01
Abstract: 1,043,532. Boring earth &c. H. HOBHOUSE. Oct. 1, 1962 [July 1, 1961], No. 15408/66. Divided out of 1,043,531. Heading E1F. Drilling apparatus comprises hydraulic motors for respectively rotating the drill, feeding the drill, and driving the flushing fluid pump, the motors being inconnected so that the feed of the drill and the supply of flushing fluid are dependent on the resistance to rotation of the drill. The motors are supplied by a pump 29 (Fig. 1, not shown), the pressure in pipe supplying the drill rotating motor 38 actuating control valves 35, 36. If the torque of the motor 38 increases above a certain value, the increased pressure in the pipe actuates the valve 36 which opens valve 46 to increase flow to the motor 45 driving the flushing fluid pump to increase the flow of fluid. The increased torque also causes valve 36 to open valve 41 so that the flow to the feed motor 42 decreases with the resultant decrease in feed. If the torque on the motor 38 increases further the valve 36 opens valves 39 and 43a so that flow through the motor 42 and the feed are reversed. A still further increase in torque on the motor 38 causes the valve 36 to open valve 37 and stop the motor. If the torque on motor 38 decreases the valve 35 opens the valves 46, 40 to increase flow of flushing fluid and to increase the feed. The drill and motors may form a unit which is driven by a feed screw rotated by the motor 42, the unit being supported by a cable for vertical drilling. The unit may carry apparatus to impregnate the wall of the hole with silicones, and the unit may incorporate apparatus for maintaining the direction of drilling.

Title: Alternating current generators
Inventor: JOHNSON EDWIN WILLIAM
IPC: G05F1/38
Filed: 1961-05-01
Abstract: 1,014,772. Protective arrangements. ROTAX Ltd. April 5, 1962 [May 1, 1961], No. 15630/61. Heading H2H. The output voltage of an A.C. generator is prevented from rising sharply upon removal of the load by arranging for the main load to be immediately replaced, when removed, byan artificial load. As shown, a transformer 1 has a saturable core carrying a primary winding 2, a control winding 9, a pilot winding 10 responsive to load removal, and secondary windings 26, 27, 28 each connected respectively to the phase lines 22, 23, 24 of the generator 25 and to the gates of controlled rectifiers 16, 18, 20 which together with rectifiers 17, 19, 21 form a full-wave rectifier through which the phase lines are connected to a resistor 15. The primary winding 2 is connected to the terminals 3, 4 of a D.C. source over the collector/emitter terminals of a transistor 5. The collector of transistor 5 is also connected to terminal 3 over a diode 6 and the emitter is connected to one end of the control winding 9 the other end of which is connected over a resistor 8 and a diode 7 to the base of the transistor which is normally non- conductive. When the pilot winding 10 receives a signal indicating removal of load from the generator, a voltage is induced in control winding 9 to render transistor 5 conductive. Current then flows in winding 2, inducing a further voltage in winding 9 to bias the transistor 5 further, and hence current flow increases. This increasing current induces a voltage in each of the secondary windings 26, 27, 28 to render the controlled rectifiers 16, 18, 20 conductive so that current can then flow from the generator to the resistor 15 until the transformer core becomes saturated. Thus, when the main load is removed, it is replaced by the artificial load constituted by the resistor 15.

Filed: 1956-05-22
Abstract: 808,578. Folding paper; sheet-delivery apparatus. KRUSE, C. May 22, 1956, No. 15839/56. Class 100(1) A folding machine comprises a frame 1, cylinders 2 of a preceeding folding device over which a once folded sheet is passed to the folding cylinders 3, 4 of a blade folding device the sheet being registered against an adjustable stop 11. The sheet is guided into the blade folding device by cylinders 6 and balls 8 so that it travels between guide rails 9, 10. The stop 11 is mounted on rails 12, 13 by means of screws 14. The blade 5 is reciprocated and the sheet folded between the cylinders 3 and 4. In the embodiment of Fig. 1 the sheet is then passed to a second similar blade folding device comprising feed rollers 20 and balls 21, guide rails 23, 24, folding cylinders 17, 18, reciprocating blade 19, and adjustable stop 25 on rails 26, 27. The whole of the second blade folding device is mounted on a frame 16 adjustable with respect to the main frame 1 by a handle 31. The sheets are stacked on edge against an end wall 32 formed on the stop 25. In the embodiment of Fig. 2 the second blade folding device is mounted vertically on frame 16 for adjustment axially of the cylinders 3, 4, and comprises blade 36, folding cylinders 37, 38, guides 50 and stop 51. The frame 16 includes a guide 41 for a slide 40 on which is mounted the blade 36. The slide 40 is provided with pins 53 engaged in holes 56 of a lever 55 so that oscillation of the lever causes the slide to reciprocate. The lever 55 includes an arm 57 carrying a cam follower 58 by means of which the lever 55 is oscillated. Two eccentric cams 59, 60 are mounted for rotation with a shaft 61 and are axially movable thereon so that one or the other may engage the follower 58. When the follower 58 engages cam 59 the reciprocation of the blade 36 is such that sheets are delivered between it and the cylinders 37, 38, for folding. When the follower 58 engages the cam 60, however, the position of the blade is such that the sheets are delivered between the blade and vertical sheet retaining rails 45. The rails 45 are adjustably mounted on a horizontal rail 43 secured to the slide 40. Sheets emerging from the rollers 3, 4 are thus ejected by the back 39 of the blade 36 and stacked against the rails 45.
