Abstract: 306,101. Allgemeine Elektricitõts-Ges. Feb. 15, 1928, [Convention date]. Track apparatus for stopping trains; interlocking .-A brake magnet b on the train is arranged in the secondary circuit i<2> of a transformer p, and a magnet. m, the armature of which, when lifted, locks the armature of the magnet b, is in series with the source of energy d in the primary circuit i'. The apparatus is shown in Fig. 1 in normal condition. The secondary current is sufficient to hold the armature of the brake magnet but magnet m is not energized by the primary current At each signalling point, a core g is mounted on the track in inductive relation to the core t on the train and carries a coil connected in a resonant circuit including contacts f on the adjacent track signal, and beyond the core g a length a of non-magnetic rail is inserted in the track. Passage of the train-core t over core g when the contacts f are closed causes magnet m to draw its armature and lock the armature of magnet b. Magnet m retains its armature for a time sufficient for the train to pass the rail a. If the core g is passed when its circuit is open, then when rail a is reached the magnet b drops its armature and the brakes are applied. Fig. 4 shows arrangements for controlling a block signalling lever l by a magnet n in series with the coil on the core g and the signal-contacts f, so that the lever l can only be operated when the signal f is at " clear." This circuit also includes an indicating device, not shown, to indicate any departure from normal functioning,

IPC: B67D7/00
Filed: 1916-04-13
Abstract: 100,861. Nicholson, G. R., and Horsley, A. B. April 13, 1916. Siphons.-A siphon is provided with liquid traps at its inlet and outlet ends, and an auxiliary siphon is connected at the outlet end. The siphon remains primed when the liquid level falls below the inlet. The main siphon a, Fig. 1, is provided with traps e, f and with an auxiliary siphon b connected to the outlet. The lower edge k of the bend m must be above the inlet trap e and is preferably at the level of the inlet c. A vent pipe n, trapped at o, is connected at the junction of the two siphons. The inlet c is connected near the bottom of the tank to be emptied, and the siphon is initially filled with liquid. Liquid is discharged by the siphon until the level in the tank falls sufficiently to allow air to be drawn in through the pipe n. The flow then stops, and the main siphon a remains filled. Any rise in the level of liquid over the inlet c causes an equivalent quantity of liquid to be displaced over the edge k. A rapid rise of the level over the inlet c causes the air to be driven out of the siphon b, which then runs full. The outlet h of the siphon may also be provided with a trap, and the vent pipe n may be constructed, as shown in Fig. 3, with a lip s and a closed lower end n<1>.

Title: Two-stage compressor of the meshing screw rotor type

Abstract: 1,220,054. Rotary compressors. SVENSKA ROTOR MASKINER A.B. Feb. 2, 1968 [Feb. 6, 1967], No. 5592/67. Heading F1F. A two-stage rotary compressor of the meshing screw rotor type comprises a housing having first and second barrel members 10, 12, Fig. 1, separated by a partition 16 and each formed with a pair of overlapping parallel bores housing intermeshing male and female rotar elements to form first and second stage compressors having working spaces 20, 22 respectively closed at their outer ends by end-plates 18, 14. The bores are all of the same diameter with the male and female rotors 40, 42 in the first stage axially aligned with the male and female rotors 44, 46 in the second stage. The female, or preferably, the male rotors are connected together to form a torsionally and axially rigid rotor unit which is supported in the end-plate 18 by a radial bearing 62 and in the end-plate 14 by a combined radial and thrust bearing 66, 68. The male rotor 40 is provided with a shaft 48 on which the male rotor 44 is shrunk after the passage of the shaft through the partition 16 The shaft 48 is formed with an axial bore 58 and radial bores 60. Fig. 2, into which high pressure liquid may be introduced to mullify the interference between the rotor 44 and the shaft 48 if it should be necessary to remove the rotor 44. Chevron-shaped compression chambers in the two stages are oppositely directed with inlet ports 24, 34 to the two stages on opposite sides of the partition 16 and outlet parts 30, 36 adjacent the end-plates 18, 14, so that axial loads acting on the shaft 48 as the result of compression of the fluid in the one stage are partially balanced as the result of the compression of the fluid in the other stage. Radial forces tending to separate and deflect the pairs of intermeshing rotors are greatest adjacent the outlets and the male rotors are radially supported at these points. The radial forces acting on the female rotors are greater than on the male rotors and the moments of inertia of these rotors are less than the male rotors hence the resistance to bending and torque is less and in consequence the rotors 42, 46 are mounted on separate shafts radially supported in the partition 16 and supported against both radial and axial loads in the end-plates 18, 14. To reduce housing deformation oil under pressure is admitted to a channel 82, Fig. 2, and is distributed to the working spaces 20, 22 through injection openings 84, 86 to cool the rotors and the housing and also act as a liquid seal therebetween. The oil also seals the two stages from each other, lubricates the bearings and passes to a space in a cover 64, the pressure therein acting on the end of the shaft 48 to further balance the axial loads on the shaft.

A process for melting and casting in the same furnace comprises arc-melting in a cooled crucible and then casting into a chill mould having its opening dipped into the melt bath, the casting being effected by establishing a gaseous pressure in the crucible higher than that in the chill mould. The mould cavity 7 is formed in the graphite electrode 6 carried by the rod 8. After vacuum arc-melting of the metal in the water-cooled crucible 3 the open end of the mould is immersed in the melt. The pressure in the enclosure is then raised by opening a valve 9b and the melt rises in the mould. By control of the pressure, the casting speed and solidification speed may be controlled so that a thin wall tube may be cast in a core-less mould. In a modification, Fig. 2 (not shown) the mould is formed as a replaceable insert in a permanent electrode. In a further modification, Fig. 3 (not shown), the mould is formed as a hollow wall cylinder concentric with the electrode 16, which may be consumable and longitudinally displaceable with respect thereto.

Patent GB-700772-A (GB)
Title: Improvements in methods of producing novolaks
IPC: B01J19/18
Filed: 1951-03-09
Abstract: Novolaks are prepared continuously by passing streams of a phenol and formaldehyde from tanks 9 and 10 to the first of a series of a minimum of three reaction vessels 1 - 5, the mixture being partially reacted in each vessel and then flowing to the next, the finished novolak flowing from the last vessel.  Catalyst from tank 11 is distributed to each reaction vessel, except the last, by conduit 32 and cocks 15-18.  Catalyst for the final reactor is fed separately from tank 6.  The degree of reaction in each vessel is so controlled, by controlling the temperature or catalyst concentration or by using vessels of different size, and the number of vessels used is such that gelatination, i.e. the production of an excessively viscous product due to the presence of an undue proportion of high <PICT:0700772/IV(a)/1> molecular weight material, is prevented.  The number of vessels required depends upon the nature of the phenol and also increases with increasing formaldehyde to phenol ratio. Preferably the extent of reaction (proportion of formaldehyde used) is the same in each vessel.  The reactors are provided with condensers 23-27. Vigorous stirring in the reaction vessels is advantageous.  In examples, a novolak is made from (1) formaldehyde and phenol in a molar ratio of 0.82 to 1 using five reaction vessels; (2) formaldehyde and resorcinol in a molar ratio of 0.49 to 1 using three reaction vessels; (3) formaldehyde and resorcinol in a molar ratio of 0.6 to 1 using three reaction vessels of different size. Figures for the number of reaction vessels required using phenol and cresol in varying ratios are also given.
