Patent GB-744851-A (GB)
Title: Process for the production of primary amines
Filed: 1953-06-12
Abstract: Primary amines are produced by a process which comprises reacting, in a first stage, an aliphatic alcohol in the vapour phase with excess ammonia at a temperature in the range 300-470 DEG  C. in the presence of a catalyst consisting substantially of iron and/or iron oxides to yield a nitrile, separating the excess ammonia, and thereafter reducing the nitrile in the liquid phase with hydrogen in the presence of a hydrogenation catalyst at a temperature in the range 80-160 DEG  C. and at a pressure above 50 kg./sq. cm.  The hydrogenation is preferably carried out over a stationary cobalt or nickel catalyst using hydrogen in excess of that formed in the first stage, and the nitrile may be admixed with an inert solvent such as methanol before the hydrogenation. In examples hexanol and a C10 oxo alcohol are converted into mixtures of amines containing (1) from hexanol 80 per cent, and (2) from C10 oxo alcohol 77 per cent, of primary amine. Specification 729,005 is referred to.

Title: Improvements in rubber elastic rings, bands or the like and a process for the manufacture thereof
IPC: B29C67/24
Filed: 1931-06-04
Abstract: Elastic rings having a predetermined and reduced amount of stretch suitable for shock-absorbers for aeroplanes, yielding connections in machines, chairs, &c., are made by cementing together an annular core and an outer sheath of rubber, one of which components is completely or partially vulcanized, and in a state of tension relatively to the other, during the uniting operation.  For example, over an unstretched cylinder of rubber on a mandrel is stretched a cylinder of vulcanized rubber of smaller diameter after the surface has been given a coat of solution.  An outer, unstretched layer is cemented on, and the whole is vulcanized and cut into rings as usual.  The contraction of the middle layer compresses the outer layers until balance is reached.  A ring of circular cross section may be made by vulcanizing a ring, stretching it, and while stretched, winding upon it a tape of rubber which may also be under tension, after the application of a cement.  Vulcanization is effected without releasing the tension.  The rings may be made of several layers of gradually altering tension.  Preferably, the inner layers are under the higher tension.

[Class 38 (iv)] [Also in Groups XX and XXXVIII] Attitude.-A directional gyroscope 18 is controlled in azimuth by the electrical output of a remote flux valve compass 17 which is kept in angular correspondence in azimuth with the gyroscope by a selsyn circuit comprising a transmitter 80 controlled by the vertical spindle 321 of the gyroscope and connected by leads 71-73 to a receiver 20 having a vertical spindle 21 carrying the core 11, Fig. 2, of the flux valve. Deviation of the gyroscope from its set direction results in a corresponding deviation of the compass from its normal east-west position (in which its output voltage is zero) so that a voltage appears in its output circuit 60, 61 the phase of which in relation to the input voltage supplied to its opposed primary windings by generator 15, Fig. 1, depends on the direction of deviation. A phase sensitive amplifier 50 senses the phase of the output voltage and excites a stationary winding 43, Fig. 2, surrounding the vertical spindle of the gyroscope, the direction of the exciting current being such that the reaction of the magnetic field of the winding and the field due to permanent magnets 42 on the rotor casing 36 of the gyroscope results in a precessional torque which returns the gyroscope to its original setting. Repeater compasses 83, 84 may be operated by selsyn receivers 81, 82. The flux valve, comprising core 11 with arcuate extremities 10 and associated primary and secondary windings, is supported by arms 22 from the spindle 21 of selsyn receiver 20 which is carried by gymbals 23, 24 provided with dashpots 90, 91.
