Patent GB-129005-A (GB)
Title: Improvements in, or relating to, Grenades, Bombs, Mines, Shells, or other like Apparatus.
Inventor: HUMPHRIS FRANK
IPC: F42C15/285
Filed: 1917-09-18
Abstract: 129,005. Humphris, F. Sept. 18, 1917 Mines, marine.-Relates to percussion firing- mechanism for mines, grenades and the like, of the kind in which the arming is delayed for a predetermined period after a safety-device is rendered inoperative. According to the invention, the firing-mechanism, comprising a weight having a coniform head adapted to release the firing-pin or striker by shock in any direction, is contained in a casing which is readily attachable to the body of the mine or like charge-container. In the application of the invention to a grenade, shown in Figs. 1, 4 and 6, the mechanism is enclosed in a casing a having two cylindrical bores a<4> and a well-like recess a<1>. Within one of the bores is a spring-actuated striker h, normally held in the cocked position by a recessed catch k, Fig. 4, which is prevented from rotating about its longitudinal axis by an elbow lever n. Between one end of this lever and a fixed part p, an inertia weight o is hung by its double-coned head o<1>. A piston i, movable in one of the cylinders a<4> containing a fluid, has an extension adapted to engage with and lock the lever n, as shown in Fig. 4. Normally all the parts are held in the safety pcsition by the engagement with the part j of a spring catch l, itself retained by a withdrawable safetyslide r. When this slide r is removed, by hand or by means of its attachment to a rifle, or otherwise, the spring l frees the part j, and the piston i is slowly moved along the cylinder a<4> by a spring i<1>. The rate of movement of the piston is determined by the escape of the fluid through an orifice g (the fluid mingling with the main explosive charge or escaping altogether), and when the part j has cleared the lever! n, the mechanism is armed. On subsequent impact in any direction, the weight o rocks, and its head rotates the lever n, which thereupon frees the catch k and allows the striker h to fire an ignition-cap. In a modification, the piston i, controlled by a fluid in a cylinder, is replaced by a rack which is geared to a speed-regulating fan. Further, the locking device j may be so designed, e.g. by slotting it, that it relocks the firing-mechanism before completing its travel, the mechanism being thus armed only during a predetedmined period. Specification 129,004 is referred to.

Title: Engine speed stagnation sensing control system
IPC: F02C7/26
Filed: 1977-03-31
Abstract: 1524796 Automatic control of gas turbines GENERAL MOTORS CORP 31 March 1977 [30 April 1976] 13566/77 Heading G3N A gas turbine engine control system detects stagnation during starting by comparing the actual speed increase of the engine over a given period with the expected increase, if stagnation is absent, and terminates the starting procedure if the expected increase is not attained. A stagnation condition exists when the engine starter drive plus the engine's own initial drive is not adequate to accelerate the engine to is operating speed. In the arrangement shown a starter switch energizes circuit 40 and the starter 26 to rotate the engine comprising gas turbine 12, 14, 16. A speed signal on line 60 passes through a sample and hold circuit 86 and has added to it a voltage corresponding to a speed increment of 60 RPM and this is compared with the actual speed some 3 seconds later as determined by the counter 94 and logic array 96 which control gate 82. If the actual speed is less than the expected speed then stagnation is present and relay coil 42 is energized to shut down the engine fuel supply. A test push 70 simulates stagnation by providing a steady signal on line 60 and this causes a light 76 to flash every 3 seconds.

Filed: 1975-04-03
Abstract: 1469048 Ignition control L G Z LANDIS & GYR ZUG AG 3 April 1975 [11 April 1974] 13756/75 Heading F4T [Also in Division G3]  A circuit for controlling an automatic igniter 12, Fig. 1, for liquid or gaseous fuels comprises means for ensuring the preservation of a safety time in the event of a temporary interruption in a supply voltage, a flame monitoring relay FR, an operating relay AR, a timer TZ based on the change in a physical parameter, contacts tz s  actuated by the timer, a switch tz 2  controlling supply of fuel and dependent on the condition of the timer arranged in the actuating circuit of the operating relay, and an operating switch contact ar 3  which is closed when the operating relay is energized, connected in parallel with the timer. The timer TZ comprises a thermal switch with two heating windings TZ 1 , TZ 11  and switch contacts tz 1 , tz 2 , tz s . The flame monitoring relay FR comprises switch contacts fr 1 , fr 2 , fr 3 , fr 4 , fr 5 , and a flame monitor 7 and the operating relay AR comprises switch contacts ar 1 , ar 2 , ar 3 . In operation, a bimetal closes switch tz s  and a thermostat 3 is closed so that current flows to neutral line 2 via components 1, 3, tz s , 4, 5, fr 1 , TZ 1 , Fig. 1. Winding TZ 1  is heated to control the pre-scavenge or safety time, a blower 6 is operated and igniter 12 is energized through closed switch fr 1  and line 11. After expiry of the safety time timer TZ actuates change-over switch tz 1  so that there is an additional current flow from line 5 to line 16 through switches fr 1 , tz 1  and thence to line 2 via switch tz 2 , diode 20, two windings 22, 23, switch fr 3  and winding TZ 11  or resistor 25. AR is actuated to operate its switches to thus hold the relay and actuate valve MV 1  to supply fuel, which is ignited. FR is actuated to operate its switches, and the ignition is switched-off, whilst contact 13 holds relay AR, switch fr 2  cuts out winding TZ 1  and switch fr 3  cuts out winding TZ 11 . Relay AR is now held by winding 23 and resistor 25. The bimetal of TZ cools and switch tz 1  switches back to apply voltage to valve MV 11  so that the greater burner output required is attained. If no flame were to be produced windings TZ 1 , T 11  arranged on the same bimetal would have actuated switch tz s  after expiry of the safety time, and the system would be de-energized. The arrangement of switches tz 1 , tz 2  may be simplified, Fig. 1a (not shown). In a modification, switch tz 2  is replaced by an electronic switch (te 1 ), Fig. 2 (not shown). In a further modification, electronic switch (te 2 ), Fig. 3 (not shown), is dependent on the condition of timer TZ, and is connected in parallel with a circuit which includes switch ar 3 , winding TZ 11 , and a further diode (33), the two circuits being connected by a fuse (35). In another modification, Fig. 4 (not shown), switch (te 1 ) is connected to the circuit including switch ar 3  by a rest switch (fr 3 ).

Title: Improvements in or relating to the preparation of sodium perborate
Inventor: SMITH JOHN
IPC: C01B15/12
Filed: 1958-04-30
Abstract: Sodium perborate is prepared by suspending a bed of particulate sodium perborate in a vertical column in a rising stream of liquor consisting of sodium metaborate solution saturated with respect to sodium perborate, introducing streams of aqueous hydrogen peroxide and aqueous sodium metaborate solution into the liquor at a point in or below the suspended bed in such amounts as to produce a supersaturation of sodium perborate on the liquor suspending the bed, particulate sodium perborate being continuously or intermittently removed from the bed.  Preferably, the process is made continuous by recycle of the liquor leaving the top of the column to the base thereof the point of re-entry being preferably below the point of entry of the hydrogen peroxide.  The supersaturation of the liquor in the zone occupied by the bed with respect to sodium perborate may be produced or enhanced by cooling, preferably by cooling a portion of the vertical column, in which case the <PICT:0911664/III/1> streams of hydrogen peroxide and sodium metaborate solution are preferably introduced into the column at points below the cooled portion.  A bed of particulate sodium perborate at a temperature of say 15 DEG -25 DEG C. is suspended in a vertical column 2 by a rising stream of liquor having a linear velocity of say 0,777-0,933 cm./sec. and of concentration with respect to sodium metaborate such that under the temperature conditions of the reaction the requirement of sodium perborate for saturation is a minimum. Stoichiometric amounts of aqueous hydrogen peroxide and sodium metaborate solution of concentration say 300 gms./litre and 600 gms./litre respectively are introduced into the liquor in column 2 through inlet pipes 8 and 9 respectively, the column being preferably constricted at the point of entry of hydrogen peroxide from pipe 8 to minimize the formation of sodium perborate encrustation.  Cooling coil 9 cools the combined liquor as they pass through the bed 1 causing supersaturation thereof with respect to sodium perborate which thus precipitates in the bed. At the top of the column cone 2a causes lowering of the velocity of the rising stream of liquor which thereafter does not suspend the particulate sodium borate and passes off from the column through overflow cone and pipe 4 to be recycled to the column through filter 5, reservoir 6, pump 3 and orifice 7.  Any suspended sodium perborate which is carried over with the liquor is removed in filter 5. Crystals of sodium perborate are withdrawn periodically through pipe 10 at the bottom of the column, the frequency of withdrawal and thus the time of retention of the crystals in the bed determining their size.  The ratio of the rate of circulation of liquor through the system to the combined feed rates of hydrogen peroxide and sodium metaborate solution is preferably within the range 75:1 to 50:1.  The preferred concentration of sodium metaborate in the circulating liquor is 15-20 gms./litre.
