Abstract: 805,902. Liquid fuel atomizers. WISTRA OFFENBAU G.m.b.H. July 2, 1956 [Aug. 1, 1955], No. 20437/56. Class 75(1) In an oil gasifying burner the pre-atomizer with multistage air supply and communicating coaxially with the fuel nozzle comprises an atomizing head provided with air nozzles and broadened internally in pear-shaped manner to 'have rounded walls narrowing in the direction of flow to communicate with a gasifying head provided with air nozzles and also broadening in pear-shaped manner so as to have rounded corner walls and having a larger internal space than the atomizing head, the two heads being supplied with air independently of one another. As shown in the drawing, an oil gasifying burner has a pear-shaped preatomizing head 2 coaxial with the fuel supply nozzle 4 and is provided with air nozzles 11 and narrows to communicate with the broad end of a pear-shaped gasifying head 3 also provided with air nozzles 13, 14 and of larger volume than the head 2 and the air is supplied to the head 2 through a conduit 23 so that it may be supplied at constant pressure and to the head 3 through a valve-controlled conduit 21 in order to operate with a sparse or excess supply of air as required. The outlet nozzles 8 and 9 are widened in the direction of flow. The air nozzles 13, 14 are distributed over the periphery of the gasifying head and are offset as to direction to effect a powerful whirling mixing of the mist entering through the nozzle 8 from the head 2. Air nozzles 15 in the outlet nozzle 9 are so inclined as to subject the flame issuing at 9 to a back-deflection to maintain the head 3 at a high temperature for gasifying the mist from the head 2. The internal diameter of the head 2 is approximately twice that of the nozzle 8 and the internal length l approximately 1.5 to 2 times the diameter of the nozzle 8. The internal diameter of the head 3 is three times the diameter of the nozzle 9 and the internal length L of the head 3 is about 4.5 times the diameter of the nozzle 9, and L/l = 3. The head 2 is formed by part of an internal casing 5 and of the end head 6 of the oil supply nozzle 4. The head 3 is formed in part by the casing 5 on to which the other part is fitted by means of a stepped recess 10. A narrow annular space 20 for the supply of additional air is formed between the narrowest part of the nozzle head, i.e. aperture 19 and the nozzle 9. The inner casing 5 is connected to the outer casing 1 by a flange 24 provided with a collar 25 secured on a tubular casing 26 provided with the air feed conduit 23 and secured in turn to an end pipe 27 having the oil feed conduit 30 and an oil regulating member 31 carried by a plug 32 and formed with a longitudinal bore 35 closed externally by a plug 34 which can be removed to allow the pipe 4 to be cleaned by means of a wire.

Title: Improvements in and relating to the production of glyoxylamide derivatives
Inventor: WHITFIELD GORDON HOWARD
IPC: B01J31/10
Filed: 1955-07-15
Abstract: Hemihydrate and hemiacetal derivatives of N : N-di-alkyl-substituted glyoxylamides are prepared by treating with a cation exchange resin a compound of the formula R1R2NCO.CH(OH)NR1R2 where R1 and R2 are alkyl groups, dissolved in a hydroxyl containing solvent such as water or a monohydric aliphatic alcohol.  The cation-exchange resin is preferably of the polystyrene sulphonic acid type.  The cation-exchange resin may be regenerated by treatment with a mineral acid such as hydrochloric acid, a salt of an amine of the formula R1R2NH and the regenerating acid being formed as a by-product.  The examples describe the conversion of a compound of the formula (CH3)2NCO.CH(OH)N(CH3)2 to N : N-dimethylglyoxylamide hemihydrate in presence of water and to N : N-dimethylglyoxylamide-methanol hemi-acetal in presence of methanol; the latter product yielding the former hemihydrate on exposure to moist air or by treatment with the theoretical quantity of water.  According to the Provisional Specification the treatment with the cation-exchange resin may take place in the absence of a solvent or in the presence of an ether or cyclic ether solvent (e.g. dioxan), the corresponding free glyoxylamide being thereby obtained.  Specification 793,807 is referred to.

Filed: 1945-08-21
Abstract: 597,466. Control of motors. GENERAL MOTORS CORPORATION. Aug. 21, 1945, No. 21296. Convention date, Aug. 28, 1944. [Class 38(iii)] The pair of parallel-connected traction motors M1 and M4 and the pair M2 and M3 can be connected in series (e.g. by contactor S) or in parallel (e.g. by contactors P1 and P2); a device connected between the motors of each pair and responsive to current unbalance therebetween has its current sensitivity automatically changed according to whether the two pairs are in series or parallel. This current-responsive device is shown as a wheel-slip relay WS1 or WS2 which responds to any difference between the currents in the two motors M1 and M4 or M2 and M3. The motors drive separate locomotive axles and are supplied by the diesel - engine - driven generator G. The master controller MC energises the solenoids a, b, c, d for adjusting the speedsetting of the engine governor, the relay SR which short-circuits the resistance SDR in series with the generator shunt field SF, the contactor S and the contactors P1 and P2. The relay SR energises the relay BR which energises the generator field-winding BF through the resistance FR controlled by the engine governor. Operation of relay WS1 or relay WS2 lights the indicator lamp L and connects the shunt R3 across relays SR and BR which accordingly drop out and weaken the generator excitation until the relative wheel slip which produces the current unbalance between the motors is reduced and the balance restored. Operation of contactor S inserts resistances R1 and R2 in series with relays WS1 and WS2 to reduce their sensitivity while the pairs of motors are starting up in series connection.
