The furnace recuperator of the parent Specification in which air entering through a duct 14 is divided into two streams 15, 16 which are respectively heated in ducts 1, 1<SP>1</SP> formed around a radiation chamber A, is modified by providing above the radiation chamber, a convection air heater B through whioh the flue gases flow after passing through chamber A, and all or a portion of the air branched to the stream 16 is directed through the heater B. All the streams of heated air are united at the discharge duct 18. In the form shown the air branched to duet 16 is divided between ducts 16a, 16b leading respectively to radiant heating passage 1<SP>1</SP> and convection heater B. The air heated in heater B may flow through a duct 19 direct to discharge duct 18 or (as indicated by chain lines) it may be directed into header 6 to receive further heat in passage 1<SP>1</SP>. A manually or thermally actuated damper 11 provided in a by-pass duct 10 extending through the heater B enables the pressure in the furnace to be regulated. A further damper 13 may be provided in the chimney 12. In a modification (Fig. 1, not shown) all the air branched to the duct 16 passes through the heater B and thence to the radiation heating duct 1<SP>1</SP> before flowing to the discharge duct 18.

Filed: 1919-07-29
Abstract: 153,361. Mann, W. J. N. July 29, 1919. Guarding against unauthorized use.-A device for locking the steering-shaft of motor and other cycles or vehicles of the kind in which a bolt engages holes in the column and shaft comprises a spring - pressed bolt adapted to be retracted by a key and held in its retracted position by a sliding bar, the whole being contained in a casing which can be attached to the steer- . ing-column by a twopart embracing member. The sliding bar and the casing may be fitted with contacts for short-circuiting the ignition when the bolt is shot. The lock comprises a bolt b, Fig. 4, engaged by a spring b<2> and fitted with a ledge b<5> which engages lips b<13> on a number of spring levers b<3> and prevents the bolt from being forced back. The bolt is retracted 'by a key which lifts the spring levers b<3> and permits the engagement of the ledge b<5> with slots b<4> therein. The lock is mounted in a casing c, Fig. 2, which is secured to the steering-column by means of two members d, lugs d<5> on which slide behind stops c<2> on the casing. Relative sliding movement between the members d and the casing is prevented by a pair of transverse bolts c<4>. The members d are connected by a bent member d<1>, a plate d' engaging slots in the membens d and d<1>, preventing relative movement between these parts. After being retracted by a key, the bolt is held in its inoperative position by a sliding bar e fitted with a recess e<3> in which the retracted bolt engages when the bar is depressed. To lock the steering-shaft, the bolt is retracted from the recess by the key and the bar raised when the bolt is free to pass through a hole in the bar into its operative position. The bottom operating-lug e<4> on the bar and the casing may be fitted with contacts which are closed to short-circuit the ignition when the bar is lowered.

Title: Process for the preparation of 2-alkyloxy-or-alkenyloxy-5-nitro anilines and their salts
Filed: 1946-06-24
Abstract: 2-Alkyloxy- or alkenyloxy-5-nitro-anilines and salts thereof are prepared by the partial reduction of 2-alkyloxy or alkenyloxy-1 : 5-dinitrobenzenes in an aqueous suspension.  The 2-alkyloxy- or alkenyloxy-5-nitro-aniline is separated from 4-alkyloxy- or alkenyloxy-3-nitro-aniline by making use of the difference in alkalinity of the said two substances, e.g. a salt of 4-alkyloxy or alkenyloxy-3-nitro-aniline is allowed to crystallise out in an acidic medium and then 2-alkyloxy- or alkenyloxy-5-nitro-aniline is obtained by increasing the pH to just over 3 and higher.  In an example, a solution of sodium disulphide and sulphur in water is added to a boiling mixture of water and 2-propyloxy-1 : 5-dinitrobenzene, and the hydrochloride of 4-propyloxy-3-nitro-aniline crystallises out on the addition of hydrochloric acid and then 2-propyloxy-5-nitro-aniline is obtained by reducing the acidity with sodium hydroxide. Specification 594,816 is referred to.

Abstract: 627,454. Coffee grinders. INTERESSENTSKABET WYTA VOORHEEN T. FOSS & CO. July 18, 1947, No. 19272. Convention date, July 10, 1946. [Class 59] [Also in Group XXX] In coffee mills of the kind provided with a mixing chamber into which the ground coffee is discharged and in which it is stirred by a rotary member, this member is connected to its driving means by a coupling which is so constructed that, when the resistance to the movement of the rotary member becomes excessive, one of its parts moves axially and causes the supply of non-ground coffee to the mill to be stopped. The mill comprises a grinding chamber 1 and a mixing chamber 2 which contains an agitator 3. The mill driving shaft 5 and the shaft 4 carrying the agitator are connected by friction gears 6, 30. The agitator is secured to a bush 19 by a pin 23 and the bush is formed with a wedge-shaped incision 21 which is engaged by a pin 20 on the shaft 4. A coil spring 24 normally maintains the spring and bush in engagement, but when the resistance to the agitator becomes excessive, the bush is moved to the left, Fig. 1, and a projection 18 thereon comes into position to engage and rock the arm 12 of a lever 12, 13, 14. This lever is pivoted at 17 to the mixer and its arm 14 normally engages an incision 15 in a longitudinally movable rod 10 and prevents its movement to the right by a spring 16.

Title: Improvements in and relating to ignition systems
Filed: 1953-07-15
Abstract: 762,097. Ignition systems. GENERAL ELECTRIC CO. July 15, 1953 [July 17, 1952], No. 19648/53. Class 7 (4). [Also in Group XXXV] Circuit arrangement.-In a discharge ignition system comprising main and triggering circuits, the main circuit, the input of which is wired to a power source, including in series a main capacitor 17, the secondary 25 of a voltage step-up low-impedance transformer 23 (see also Group XXXV) and an igniter 28 which is connected to the output end of the main circuit, and the triggering circuit, which discharges through the main circuit, including a triggering capacitor 20, a current limiting resistor 21 therefor, and an auxiliary gap 24 in series with the triggering capacitor 20 and the primary 22 of the low-impedance transformer 23, the resistance of the main discharge circuit is less than the minimum value for prevention of oscillation. A high reactance step-up transformer 10 is provided with an air-gap 12 in a magnetic shunt between those parts of the core upon which the primary and secondary windings 13, 18 are wound ; the primary winding 13 is connected via a capacitor 14 to the A.C. power source whilst the capacitor 17 is fed with D.C. from the secondary winding 18 through a selenium rectifier 19. The capacitor 14 serves to limit the circuit current, offset the lagging power-factor resulting from the reactance of the transformer 10, and together with the latter's magnetizing reactance produces a stabilizing effect which minimizes fluctuations in the source voltage; the reactance of the capacitor 14 is greater than the unsaturated magnetizing-reactance of the transformer 10. The rate of sparking of the system is determined by the elements 10, 14, 17, 20 and 21 while the capacitor 17 and transformer secondary 25 comprises a clamped series-resonant circuit when the ignition-plug gap is sufficiently ionized to be conducting. In a modification the main discharge path of the storage capacitor includes both the primary and secondary of the low-impedance transformer which latter may either be of the autotransformer or insulated type. Electrical values and formulae relating to the circuit and components are given. Operation.-The triggering capacitor 20 which is charged more slowly than the main capacitor 17 because of the resistor 21 breaks down the gap 24 and discharges through the primary winding 22, the resulting high voltage in the secondary winding 25 ionizing the gap of the igniter 28 whereupon the main capacitor 17 discharges into the secondary winding 25 and across the igniter 28, some of the energy being stored in the transformer 22, 25 which then discharges to continue the delivery of energy to igniter 28 and to recharge the capacitor 17 with the opposite polarity. This oscillation in the inductance capacitancespark gap circuit continues until the stored energy is dissipated.
