Title: An oxygen steel-making process
IPC: C21C5/30
Filed: 1965-01-19

Abstract: 1,211,512. Derivatives of decenol and decenoic acid; organomagnesium compounds. R. FIRMENICH, G. FIRMENICH, R. E. FIRMENICH, and F. H. FIRMENICH, [trading as FIRMENICH & CIE]. 15 Jan., 1969 [17 Jan., 1968], No. 2400/69. Headings C2C and C2J. [Also in Division A5] Novel derivatives of decenol and decenoic acid of the formula wherein a double bond is located in one of the positions indicated by dotted lines and R is CO 2 H or CH 2 OH and n is 1 or 2 (cis and trans isomers) are prepared by saponifying and partially hydrogenating esters of the formula containing two conjugated double bonds in two of the positions indicated by the dotted line and wherein R<SP>1</SP> is a C 1-4  aliphatic radical, and, if desired, reducing the resulting compounds to give compounds of the above Formula I in which R is CH 2 OH. trans-3-Methyl-4-decenoic acid may also be obtained by oxidizing 3-methyl- 4-decen-1-al, which is made by condensing croton-aldehyde with n-amylmagnesium bromide and refluxing the resulting 2-nonen-4-ol with ethyl vinyl ethers in the presence of mercuric acetate. cis-3-Methyl-3-decenol, which may be oxidized to the corresponding acid, may be prepared by condensing ethylene oxide with the magnesium derivative of cis-2-bromo-2- nonene, obtained by treating a suspension of magnesium turnings in tetrahydrofuran with a solution of cis-2-bromo-2-nonene in tetrahydrofuran containing a trace of ethyl iodide, the cis-2-bromo-2-nonene being obtained by refluxing a pyridine solution of 2,3-dibromo-2- methylnonanoic acid resulting from the bromination of 2-methyl-3-nonenoic acid. cis-3-Methyl- 4-decenoic acid, which may be reduced to the corresponding alcohol, may be prepared by partially hydrogenating 3-methyl-4-decynoic acid resulting from the decarboxylation of 3-nonyl-2- ylmalonic acid, obtained by saponifying the corresponding diethyl ester, which is in turn made by adding diethyl malonate to 2-bromo-3- nonyne obtained by reacting phosphorus tribromide with 3-nonyn-2-ol resulting from the reaction of 1-heptyne with ethylmagnesium bromide and acetaldehyde. Methyl 3 - methyl - 2,4 - decadienoate (cis and trans at C-2) and methyl 3-methyl-3,5-decadienoate are obtained by adding a mixture of hexanal and trimethyl 2 - methyl - 3 - methoxycarbonylallyl-phosphonate resulting from heating methyl 3 - methyl - 4 - bromo - crotonate with trimethyl phosphite, to a suspension of sodium amide in tetrahydrofuran.

The first anode consists of a flanged disc 4 with a small central aperture, mounted very close to the cathode and insulated from the cylinder 3 by mica discs bolted on the underside, one of the discs fitting around the cylinder 3. The second lens comprises a cylindrical anode 5 and a third anode 6 consisting of a perforated disc. The cylinder 5 is insulated from the anode 4 by a mica ring 15<a>, and from the anode 6 by a mica ring arranged in a depending skirt. Deflecting plates 7, 8 are mounted on rods 16 .. 19 carrying the anodes 4, 6, and deflecting plates 9, 10 are mounted on rods 29 on a mica ring 21 secured to the rods 16 .. 19.

In a gas-discharge device (see Group XL (a)), used in a pulse distributer, the intercathode capacity is formed by mounting a series of nickel washers 2 which form the cathode on insulating rods 30 having a pair of washers 18 of mica or ceramic between adjacent cathodes. Input pulses are fed to the control electrodes 4 via capacitors which are formed at the same time as the control electrodes by deposits on a conducting rod 10 which has been previously coated with an insulating film 32. For example, the rod may be of aluminium and the coating of aluminium oxide, the control electrode being deposits of silver platinum or carbon and simultaneously constitute electrodes of the condensers. When carbon is used the deposition may be effected from a colloidal carbon suspension within isopropylic acid or alcohol. When platinum is used it may be effected by deposition from platinum tetrachloride or when silver is used from a mixture of powder silver and glass flux which is then heated.

Title: Apparatus for reading a record carrier with an optically readable information structure
IPC: G11B7/09
Filed: 1977-01-25
Abstract: The reading-out device is intended to allow centring errors to be detected by means of as small as possible number of additional optical elements. The read-out beam (b) of a helium-neon laser (6) is reflected from a mirror (9) to a system of lens (11). A radiation spot is produced on the surface (2) of the information structure of the recording carrier (1). The read-out beam (b) reflected from the information structure is reflected by a semi-transparent mirror (8) to a radiation-sensitive detection system (12). A deviation between the centre of a read-out spot projected on the information structure and the centre line of this track to be read out is established using the detection system (12). With the aid of the detection system (12), a reference signal is obtained, which is used for correcting the position of the read-out spot with respect to the track to be read out. The detection system (12) is formed by four radiation-sensitive detectors. <IMAGE>

Title: Improvements in and relating to actuating mechanism for control rods
Inventor: HANSON DOUGLAS OLIVER
IPC: G21C7/14
Filed: 1962-01-26
Abstract: 967, 513. Controlling nuclear reactors. NUCLEAR POWER PLANT CO. Ltd., and A.E.I. - JOHN THOMPSON NUCLEAR ENERGY CO. Ltd., [trading as NUCLEAR POWER GROUP]. Dec. 17, 1962 [Jan. 26, 1962], No. 2968/62. Heading G6C. An actuating mechanism for. a nuclear reactor control rod 10 comprises a winding drum 7 around which passes a rope or chain 9 supporting the rod and which is driven by a motor 1 through a gear reduction unit 4 housed in a casing mounted on bearings so as to be free to rotate about the axis of its coaxial input and output shafts 1a, 4a, an electromagnetic clutch 2 acting, when energized, on the casing to'lock it in position to enable the drive from the motor 1 to be transmitted to the drum 7. As shown, the clutch 2 comprises a coil and a magnetic core fixed to the frame 3, the magnetic flux from the core traversing a small air gap to a disc 2b pf magnetic material rigidly fixed to the gear casing. The disc 2b and the magnetic core are provided with a number of slots which form in effect magnetic teeth on each member and this provides a strong magnetic lock between the core and the disc when the coil is energized. Under emergency conditions, the clutch 2 is released and the rod 10 falls under its own weight into the reactor core. The tendency for the torque produced by the weight of the rod 10 acting on the drum radius to drive the motor 1 when the gear casing is held fixed by the clutch 2 can be overcome by incorporating a single worm-wheel in the gear unit 4, the torque exerted by the rod 10 then being solely opposed by the action of the clutch 2. Supplementary means for raising or lowering the rod and also for locking it in position and which are manually operated, but which could be operated from a separate power supply, comprise a spring loaded shaft 14, the upper end of which is covered by a plate 15 and at the lower end of which is a pinion 16. On removal of the plate 15, a winding tool 17 with a reversible ratchet 17a may be inserted and downward pressure applied to the shaft 14 to cause the pinion 16 to engage a gear ring 4c on the gear casing. A drive can then be transmitted to the drum 7 and the control rod raised or lowered, depending upon which way the ratchet 17a is connected. The provision of the ratchet 17a serves to lock the rod 10 in any given position except when the tool 17 is being turned. With the actuating mechanism described, a large gear reduction can be employed between the driving motor and the winding drum and hence the .notor used can operate at mains frequency and still drive the control rod at the desired low speeds. The high inertia of the reduction gear does not affect the rate at which the control rod falls under emergency conditions because the larger part of the reduction gear is by-passed by virtue of the gear casing being free to rotate.
