Title: Improved means for distributing stone dust in coal mines
IPC: E21F5/10
Filed: 1920-05-13
Abstract: 155,176. Davies, D. May 13, 1920. Wagons. - A truck containing stone dust and intended to be employed in a coal mine one at either end of a train of coal trucks to reduce the danger of explosion from the coal dust, has at one or both sides a chamber b communicating with the body a by means of orifices c through which the stone dust can pass. Within each chamber b is a paddle wheel d mounted on a spindle e which has at one end a sprocket-pinion g adapted to be driven by a, chain h from a sprocket on the axle of one pair of running wheels m. The spindle e is surrounded by a sleeve f where it passes through the body a. The jolting of the truck causes dust to pass from the body into the chambers b, whence the revolving paddles deliver it upwardly to be deposited in a similar manner to the coal dust it is intended to mingle with. Where one stone dust truck only is employed it is preferably placed at the rear of a train of coal trucks.

Title: Process for the preparation of nitro substances

Abstract: 501,034. Nitro compounds ; ethereal nitrates; explosives. KATAYLT-CHEMIE AKT.-GES. FLIMS. May 14, 1937, No. 13627. Void. Convention date, May 14, 1936. [Class 2 (iii)] [Also in Group XXI] In the preparation of nitro-compounds and nitric acid esters, nitration is effected in the presence of a catalyst comprising a compound of Cr, W, Mo, Ta, Cb, V, Ga or In, for example phosphomolybdic or phosphotungstic acid or vanadium phosphate. Highly nitrated compounds can be made, in a single stage; e.g. a mixture of tetra- and pentanitronaphthalene is produced by catalytic nitration of naphthalene at 75‹ C. Glycerine nitrated in the presence of a molybdenum catalyst gives a product of reduced sensitiveness to shock but of increased explosiveness. Mixtures of, for example, naphthalene and pentaerythrite can be highly nitrated to yield a shock-proof explosive. Initiating agents may be prepared by treating the shock-proof compound, e.g. hexanitronaphthalene, made by the process with oxygen-yielding substances such as ammonium perchlorate or barium peroxide dissolved, together with one of the said catalysts, in a weak acid such as formic.

Title: Improved method and system for generating polyphase alternating current
IPC: H02P1/16
Filed: 1953-05-18
Abstract: 745,748. A.C. Commutator machines. IGRANIC ELECTRIC CO., Ltd. May 18, 1953 [May 29, 1952], No. 13890/53. Class 35. Polyphase current is derived from a series of mechanically connected commutator machines by feeding the field winding of each machire from another machine in sequence through a phase-shifting condenser and resistance, one of the machines having an auxiliary field winding enabling it to build up a starting voltage. The invention is shown for three generators 10, 12, 14, providing a three-phase supply to lines L1, L2, L3, the armatures 16, 18, 20 being shunted by field windings 24, 26, 22 respectively of the next successive machines. Machine 10 has an auxiliary field winding 44 connected, at starting, through resistances 46 and 48 across the armature 16. As the voltage builds.up the normally closed contacts 42b of relay 42 connected across the armature opens, thus introducing condenser 50 into the circuit to produce resonance. This causes the machine to act as a self-excited A.C. generator. The A.C. voltage produced gives rise to an excitation of field winding 24 through condenser 28 and resistor 30, and a voltage is generated in armature 18 of machine 12 lagging by 120 degrees on that in machine 10. This in turn excites machine 14 in the same way and the coil 40b of relay 40 is connected across this machine to disconnect the auxiliary winding 44 at contacts 40c and connect field windings 22 of machine 10 at contacts 40a at a predetermined voltage, leaving each machine separately excited by another machine in the correct phase. Specification 658,732 is referred to.

Abstract: 608,039. Automatic control systems for vehicles. DOLL, H. G. June 4, 1945, No. 13981. Convention date, July 17, 1943. [Class 38 (iv)] Steering.-In an automatic vehicle steering control device the steering member is adjustable in accordance with a function of both the angular deviation of the body from a predetermined course and the rate of change of the angular deviation. In Fig. 4, the device 10 provides a voltage proportional to the magnitude of the angle of deviation of an aircraft A from its required direction of flight, and consists of a universally mounted gyroscope 11 to which a mirror 12 is fixed. Light from source 13 is reflected from 12 on to photocell 14 through a screen-15, designed to render the amount of light incident in 14 a predetermined function of the angular position of mirror 12 and hence also of the aircraft. The output of cell 14 is fed to amplifier 17 which provides a D.C. voltage proportional to the angular deviation. The device 18, of known construction, provides a D.C. voltage proportional to the rate of change of the deviation. The electrical outputs of both units 17 and 18 are applied to " solver " 19 which is of the form disclosed in Specification 588,608, [Group XIX]. The aircraft A is steered by rudder R adjusted by constant-speed motor 76 fed from source 77 through reversing mechanism 78 actuated by solenoid 79 which is energized from battery 80. The relay 83 selectively actuates the contact arm 82 to determine the direction of motion of R and is energized by the difference voltage between the output of solver 19 and a biassing voltage tapped off from a potentiometer 91 by an arm 94 driven simultaneously with the rudder R so that the biassing voltage varies in magnitude and sense with the rudder deviation from normal position.
