Title: A process for the isomerisation of chlor-alkanes
IPC: B28B11/14
Filed: 1939-11-27
Abstract: 535,435. Isomerization of chlor-alkanes. FIFE, J. G. (Naamlooze Vennootschap de Bataafsche Petroleum Maatschappij. Nov. 27, 1939, No. 30873. [Class 2 (iii)] Mono- or poly-chlor-alkanes containing less than 10 carbon atoms in the molecule are isomerized by treatment with acid acting metal, halides or boron halides, at temperatures below 200‹ C. The halides preferred are aluminium chloride, double compounds thereof such as Gustavson compounds or boron fluoride. The reaction may take place in the presence of activating compounds such as hydrogen halides. These compounds also check the decomposition of the chlor-alkanes. The catalysts may be used in combination with carrier materials such as active charcoal, silica gel, pumice, kaolin, and activated aluminium oxide. The reaction may take place in the gaseous or the liquid phase and under normal, raised or reduced pressure. The effect of the isomerization process of the present invention in the case of dichlor alkanes is to space further apart the chlorine atoms in the molecules and in the case of monochlor alkanes to shift the chlorine atom from one carbon atom to another. In an example, 1:2-dichlorbutane is treated with aluminium chloride in a U  2 A steel autoclave in the presence of hydrogen chloride at 10 atmospheres pressure at 30‹ C. The dichlor alkanes produced by the process of the invention may be used as initial materials for the production of dicarboxylic acids used in synthetic resin preparation.

The stand pipe 6 is connected at its lower end to the valve 2 and slidable, through a gland 13, into the interior of the chamber. In operation, with the valve in the position shown, water is fed from a header tank through the pipe 4, valve 2 and pipe 6 into the chamber 7 until by the connection of a riser vent 18 and riser tube rising above the level of the liquid in the header tank, the liquid level in the riser tube is the same as that in the header tank; the valve 2 is then rotated by a handle 3 so as to connect the duct 5 with the stand pipe 6, water then discharging from the chamber until the level of water therein corresponds with the top of the pipe 6; the handle 3 may be replaced by a solenoid and the stand pipe arranged to be interchangeable with another of a diffrent length. In a modification, the bracket 11 is formed with a slot so that it, together with the screw 8, may be raised or lowered and thus increase the range of adjustment of the chamber 7.

Title: Process for the manufacture of stainless steel
IPC: C22C38/40
Filed: 1962-08-14
Abstract: A process for the production of a stainless steel containing 12-18.25% chromium comprises preparing a pig-iron melt containing less than the required amount of chromium in a combustion type furnace, transferring the molten pig-iron directly into an open refining vessel wherein it is blown with oxygen until the temperature rises to at least 3100  DEG F. and, while the temperature of the melt is 3100  DEG F. or above, introducing chrome bearing ingredients to produce a stainless steel having the required chromium content.  The slag from the first process may be transferred to a separate reaction vessel and treated with a silicon containing reagent to recover the chromium content thereof which may be returned to the open refining vessel to adjust the chromium content of the melt therein Alternatively the silicon reagent can be added to the slag still in the refining vessel after the end of the oxygen blow.  In a modification of the process, a pig iron containing chromium may be directly transferred to the refining vessel and subjected to the oxygen blow therein but the original melt must contain sufficient silicon (e.g. at least 0.5%) to restrict the oxidation of the chromium until the temperature of melt reaches at least 3100  DEG F. As an alternative to using chromium ores to supply the chromium in the original pig iron, chromium bearing coke may be used.

Abstract: 1433377 Projectile fuzes MESSERSCHMITTBOLKOW-BLOHM GmbH 2 July 1973 [15 July 1972] 31333/73 Heading F3A A fuze comprises a housing 1, Fig 1, and a wind wheel generator G which is automatically extended by a spring 3 to the position shown in Fig. 2 when an explosive body carrying the fuze is expelled from a warhead or other container. In this position the generator is exposed to air flow, and, in one embodiment, charges two capacitors. When the voltage of one capacitor exceeds a threshold set by a diode an electric primer 20 is fired and the gases therefrom displace the generator further and thereby deform an element 16 locking a rotor 23 in a safe position. The rotor is then moved by a spring 25 to an armed position where a detonator carried by the rotor is ignited by another primer which is supplied, after a delay, with current from the second capacitor. Switches in the circuitry are operated by movement of the rotor. In another arrangement, one capacitor is used and the said other primer is fired by a current from a battery activated by the primer 20. In a further arrangement, the electric circuitry includes a filter which delays firing until a certain falling rotational speed of the generator has been reached. 1433379 Plate heat exchangers NEV MASHIINO STROITEL ZAVOD IM VI LENINA 18 Aug 1973 39150/73 Heading F4S A heat exchanger comprises a plate stack consisting of corrugated plates 1, Fig. 2, alternating with corrugated plates 2 Fig. 3, the assembly providing undulating flow channels 4, 5, Fig. 5, for the heat exchanging fluids, fluid distributing and collecting zones 14, 15 in communication with the respective channels being formed at the ends of each plate, and the plates having formed therein means for mutually supporting and spacing the plates, said means preferably also serving to turbulate the fluids.

Title: Weighing machinery
IPC: G01G11/00
Filed: 1937-11-15
Abstract: 505,639. Weighing - apparatus fitted to conveyers. SOUTH METROPOLITAN GAS CO., and NOURSE, T. W. Nov. 15, 1937, No. 31394. [Class 143] In an indicating device for an apparatus subjected to a continuously variable force or load, for example a conveyer-belt weighing- machine, the variations from normal of the force or load are indicated by the relative movements of two blocks or members one of which is periodically displaced from a datum position an amount dependent on the force or load and the other is moved in sympathy with the first block within the limitation imposed by a fixed " normal displacement " stop, means being provided to complete the movement of the second block up to the fixed stop if the displacement of the first block is insufficient to do so. The invention is described in connection with a weighing-machine wherein the weight of material carried on a conveyer belt displaces a lever arm A, Fig. 5, which is periodically gripped whilst a measuring quadrant F is moved by a spring K into contact with the lever when permitted to do so by a cam L acting through a lever H and link G. During the return stroke to the position shown in Fig. 5, (effected positively by the cam L), the movement is passed as usual through a clutch to a counter registering the load. According to the invention, two blocks 1, 2, Fig. 3, in frictional contact with each other are provided, the block 1 being moved to-andfro in unison with the lever H, Fig. 5, and measuring quadrant F, and the block 2 being similarly moved by the frictional contact of the block 1 except that the movement of the block 2 towards the right is limited by a fixed stop in the path of a lug 6<1> on the block. When in engagement with the fixed stop, the block 2 is in a zero position corresponding to a normal load on the conveyer. If, owing to a sub-normal load on the conveyer, the stroke of the block 1 is insufficient to bring the block 2 against the fixed stop, a cam-operated weighted lever 9 completes the movement. If the load increases or diminishes, the stroke of the block 1 is correspondingly increased or diminished and owing to the periodical zero setting of the block 2, a relative movement occurs between the two blocks. This relative movement, which is an indication of the departure from normal load, is indicated by coloured lamps in circuit with contacts 12 on the block 1 engaged by a wiper arm 15 on the block 2.
