Abstract: 354,919. Motors. TRIGGS, W. W., 57, Lincoln's Inn Fields, London.-(Eclipse Aviation Corporation ; 545, North Arlington Avenue, East Orange, New Jersey, U.S.A.) June 13, 1930, No. 18221. [Class 35.] Rotary machines; brush-holders ; terminals and accessories, arrangement on machines.-An engine starter of the inertia type comprises a flywheel which constitutes the armature of an electric motor and may be set in rotation by hand or by electrical means disposed within the flywheel. As shown, the flywheel comprises a disc 14 to which are secured laminations 15 provided with internal slots for carrying conductors 18 leading to the commutator 19. Field poles 22 within the flywheel are secured to the end wall 21 of the casing 20. The shaft 13 of the flywheel is provided with a pinion 9 connected by gears 8, 7 to a gear wheel 5 in which slides a jaw clutch 4 movable into engagement with the clutch member 6 on the engine shaft by means not shown. When the flywheel is to be driven electrically, a hand switch 39 closes the circuit of a solenoid 36, the plunger of which switches on the motor by means of a contact member 41 bridging contacts 34, 35. The plunger of the solenoid also causes the brushes 28, which are pivoted at 24 and are normally held out of engagement with the armature by a spring 31, to come into engagement with the commutator; this is effected through a lever 43 engaging the rod 29 on which the brush springs 31 and brush-holders are mounted. The brush gear and solenoid are protected by a detachable cover 45.

Title: Improvements in pyrophoric compositions of zirconium and lead and method of producing same
IPC: C22C16/00
Filed: 1947-07-11
Abstract: A pyrophoric composition comprises 20-75 per cent Pb and 25-80 per cent Zr the total content of Pb and Zr being not less than 60 per cent.  The composition may contain also Ti e.g. 10-20 per cent and/or one or more of the metals Fe, Ni, Co, Mg, Al, Sb, Mn and Sn.  A method of making the composition comprises heating a mixture of small pieces of Pb and Zr in an inert atmosphere e.g. to 1350 DEG -1600 DEG C until the whole is liquefied and thereafter cooling the composition.  Thus the melting may take place in a vessel which is evacuated and then filled with inert gas.  Zr may be partly or wholly added in the form of its hydride.  Ti, when used, may be added either as metal or as its hydride.

Abstract: 1,199,806. Boiler furnace fronts. COCHRAN & CO., ANNAN Ltd. 23 April, 1968 [24 April, 1967], No. 18686/67. Heading F4B. A lagged triple pass shell boiler 1, surrounded by a spaced casing 8, is provided with a circular closure door 10 which carries a burner assembly 12 and forms a lagged annular air duct 13 through which combustion air from the space between the casing and the shell, is led to the burner. Whilst flowing from passage 14A in both directions around the annular duct, the combustion air extracts heat from the combustion products flowing between tube sets 3 and 4, through a transfer base defined between partition plate 15 in duct 13 and tube sheet 5, thereby cooling the furnace front. The heated air then passes through ducts D and E and a fan to the burner. In a modification (Fig. 3, not shown) the fan is mounted adjacent an air inlet in the casing, the air supply from which to the door duct is regulated by a damper, and the combustion product transfer base is wholly defined within the boiler shell. Heated combustion air from the annular door duct passes into a baffle containing air bore within the boiler shell to be led to a burner tunnel.

Abstract: 1,271,189. Briquetting coke. METALLGESELLSCHAFT A.G., and BERGWERKSVERBAND G.m.b.H. 21 April, 1970 [23 Aug., 1969], No. 19083/70. Heading B5A. An apparatus for forming coke briquettes, comprises a heavy duty mixer with two screw blades 23 that rotate in the same direction, a caking coal inlet 4, and a coke inlet 5, an outlet 28 which discharges the mixture to an intermediate storage vessel 2, with a stirring mechanism that rotates about a vertical shaft 7, and at least one briquetting press 3, the inlet of which is controlled by a gate 13 and flap 14, the level of the mixture in the vessel 2 being maintained at 15 by varying the speed of the press 3 in response to indicating devices, e.g. radio-active indicators 16 and Geiger counters 7. In operation, the coke is heated to a temperature of, e.g. 750 C., above the range at which the caking coal is plastic and mixed with the coke in the mixer 1 at a temperature of, e.g. 480 C., at which temperature the coal is still plastic, the mixture is then held in the vessel 2 to ripen for 20-300 secs. in a layer having a constant height 15 before being passed to the press 3. A vent 19 passages gases to a condenser. The mixer blades 23 have a greater angle of inclination to their shafts at the inlet end of the mixer, and each is formed with a replaceable tip 24. The stirring mechanism on the shaft 7 is formed by arms 8 with iron cross-members 9 which sweep the inside wall of the vessel 2. Stationary pins 11, which may have cross-members, prevent the mixture rotating as a compact body. A cooling liquid is passed through the mixer shafts 20, 21. The mixture can also be cooled by adding cold coke. The pressure in the apparatus is maintained constant below atmospheric pressure. The level of the mixture in the vessel 2 may be maintained by measuring the variation in torque of an electric or hydraulic motor driving the shaft 7.

Abstract: 464,549. Rolling; bending. SCHLOEMANN AKT.-GES. July 10, 1936, No. 19142. Convention date, July 15, 1935. [Class 83 (iv)] Winding.-In automatically coiling strip metal on a driven drum the drum segments 18 are expanded outwards to frictionally grip the first layers of the coil, the guides 24 and the rollers 23 which guided the first layers on the drum being then withdrawn by levers 25 and crank B. To release and discharge the coil the operating rod 20 is moved in the opposite direction to withdraw the segments 18 radially inwards by links 17 and also axially within the sleeve 11 so leaving the coil to sink on to a receiving trough 31 which is then moved outwards where it can be removed by a crane hook 35. One of the guide rollers 28 remains in contact with the coil and acts as a feeler to operate a regulator 30 for counteracting the torque of the driving motor 12 as the coil diameter builds up. The trough 31 may have drive rollers to rotate the coil and bring its end to the top. In a modification the drum segments are not axially withdrawn inside the sleeve but stripping cams (48) are provided instead. The drive of the motor, the shrinking and expanding of the drum segments and the coil removal mechanism may be synchronized (not described in detail).
