Title: Improvements in or relating to rock bolts
IPC: F16B13/06
Filed: 1960-02-17
Abstract: 912,987. Rock bolts. EMERY, C. L. May 15, 1961 [Feb. 17, 1960], No. 5566/60. Class 45. A rock bolt has a round stem 3, an expandible anchor 6 and a wedging unit (9, 20 and 14). The stem 3 is tensioned by a hydraulic jack 18 having jaws 16 so that the wedge 5 expands the anchor 6 (grooves 23 facilitating this by aiding deformation). When the jack jaws 16 release, the jaws 14 hold the stem 3 under tension and hence the anchor 6 in place. The plate 9 and jaw holder 20 may be separate (9A and 20A, Fig. 4, not shown) also the stem 3 may be a cable (3A, Fig. 12, not shown).

Title: Improvements in or relating to Gear Cutters.
Inventor: GLEASON JAMES EMMET
IPC: B23F21/22
Filed: 1917-04-25
Abstract: 109,608. Gleason, J. E., and Stewart, A. L. April 25, 1917. Gear-cutting; milling-cutters. - Gears with curved teeth are cut by a process in which both the gear and the cutter rotate continuously as in hobbing. For this purpose the teeth x, y as seen in plan, Fig. 5, are curved to an arc of a roulette and successive cutter-teeth enter successive blankspaces. Fig. 5 shows the arrangement for cutting a wheel and Fig. 6 that for cutting a pinion. The cutters preferably cut on one side only and may be arranged alternately as shown in Fig. 7, in which case alternate teeth of the gear are finished on alternate sides at the first setting and the blank is set over to complete the cutting. In a modification, the cutters are grouped in pairs with opposite cutting edges, those of one pair c, d, Fig. 8, acting on both sides of one tooth space in the gear, that is thus finished at one setting. The inserted blades are adjusted radially on the cutter heads by wedges 7, Fig. 1, controlled by screws 8 and are clamped by bolts 4. 13, Figs. 1 and 2, is the cutting face and 15 are the cutting edges.

Abstract: 606,544. Jet-propelled aircraft. AKT.-GES. BROWN, BOVERI, & CIE. Feb. 25, 1946, No. 5879. Convention date, Dec. 29, 1945. [Class 4] [Also in Group XXVI] Aircraft propulsion plant comprises a cellular engine of the pressure-exchanger type such as described in Specification 553,208, [Group XXVI], the cells of which are scavenged and filled by the relative wind, the pressure of the air in the cells being raised by ram effect and pressure wave, the fuel being then ignited, and the products of combustion discharged rearwardly to furnish the propulsive force. In the form shown, the engine comprises an annular series of cells 1, 2, 3, 4, 5, ... rotating between two fixed end discs with inlet and outlet openings 13, 14. A typical cycle of operations consists of scavenging by the relative wind in positions 1 and 5, Fig. 1, compression by ram effect and pressure wave in positions 2 and 3, ignition of the fuel in position 3 and expulsion of the products of combustion in position 4. As shown in Fig. 2, the rotation of the cells may be assisted by the passage of the gases over the curved radial walls of the cells 1-5. In an alternative arrangement the cells are stationary and the end discs rotated. Fig.- 4 shows an engine arrangement comprising two propeller jet engines for takeoff, and four cellular-type engines for boosting purposes.
Patent GB-118248-A (GB)
Title: An Improved Signalling Device for use in connection with Colliery Winding Engines.
Inventor: DAVIES ALBERT EDWARD
IPC: B66B19/06
Filed: 1918-04-06
Abstract: 118,248. Davies, A. E., and Brown, F. M. April 6, 1918. Order apparatus; mine signalling systems. - An electrically-operated signalling device for use in connexion with colliery winding engines comprises a magnet 1 and a solenoid 2 both in the same circuit which is closed by a switch 4 operated by hand or by the pull rope. A pointer 8 is loosely mounted on a fixed axle 11 and is connected to a ratchet wheel 7 provided with a stop 9 and spring controlled so as normally to bring the stop 9 against a stop 10 on the axle 11. A second solenoid 13 has a core 15 which, when the ratchet wheel 7 is moved by a pawl 6 on a lever 5 attracted by the magnet 1, falls in between the stops 9, 10, and prevents the pointer 8 returning to zero till the solenoid 13 is excited by the closing of its circuit by starting of the engine or by hand. The solenoid 2 has a cross-bar 18 on its plunger 17 which is controlled in its fall by a dash-pot 21. A projection 23 on the cross-bar 18 trips a lever 24 when rising and lifts a retaining pawl 26, and by a pin 27 thereon also the actuating pawl 6, clear of the wheel 7, thus allowing the pointer to fall back to the No. 1 indication. The parts are designed so that, on closing the switch 4, the wheel 7 is moved one tooth before the projection 23 rises to lift the pawls 6, 26, and when this occurs immediately afterwards the core 15 has already fallen to prevent return of the wheel 7 and pointer 8 to zero. Subsequent closings of the switch 4 belonging to the same signal will take place before the projection 23 has time to fall below the trip lever 24, and so are recorded. In the event of the signal not being answered, sufficient time will have elapsed before it is considered necessary to repeat the signal for the projection 23 to fall below the lever 24, and on making the first contact of the repetition the pointer will be released to fall back to the No. 1 position and subsequent contacts will be added on as before. Starting of the engine, or otherwise, excites the solenoid 13 and raises the core 15 and with it a hooked &c. rod 28 which lifts the pawls 6, 26, so allowing the pointer to return to zero. The ratchet wheel 7 may be geared to the pointer 8 to increase the movement of the latter. A series of lamps may be used to give the signal, and rotary contacts are described whereby lamps are successively lit, the earlier ones in the series either being extinguished or remaining lit as the signal proceeds.
