Title: Oxidation of saturated hydrocarbons to alcohols
IPC: C07C29/52
Filed: 1967-11-14
Abstract: The preparation of alcohols by pastial oxidation of a saturated hydrocarbon in the liquid phase with molecular O 2 in the presence of a boron compound capable of forming an ester of the alcohol, whereby a reaction product containing borate ester or esters of the alcohol and hydroperoxides (i.e. any organic compound containing a peroxy oxygen atom) is obtained, from which the alcohol from said ester or esters is recovered, is improved by maintaining the reaction product at 125-200 C. for at least 5 mins., after the O 2 flow has ceased and before processing to recover the alcohol. The "heat soaking" step decomposes the hydroperoxides and increases the yield of alcohol. In examples, batch-wise and continuous processes wherein cyclohexane is oxidized to give cyclohexanol with by-product cyclohexanone, in the presence of metaboric acid are described. The oxidation reactions were carried out at 165 C. and 125 p.s.i.g., the "heat soaking" being at the same pressure and at 165 C. for 30 or 100 mins at 175 C. for 20 or 30 mins., at 125 C. for 120 mins., at 150 C. for 60 mins., and at 200 C for 10 mins.

Title: Rail vehicle control systems
IPC: B61L3/08
Filed: 1969-12-06
Abstract: In an arrangement for automatically controlling a train 10 to a halt at station platform 11, pick up coils 16 on the train receive a track signal from unit 13 having a frequency which is a function of the distance to stop and this signal is applied with a signal from axle driven generator 14, having a frequency proportional to train speed, to a control circuit providing an output E for controlling train brake and speed control equipment 17. The track between unit 13 and the leading axle of the train forms a variable inductive element which controls the frequency of an oscillator circuit in the unit, which thus supplies a signal to the track rails having a frequency inversely proportional to the root of the distance to stop. A voltage analogue of this signal is provided by unit 18 and supplied to a multiplier 20 which receives as second input an analogue of the speed signal supplied from generator 14. If the train is decelerating correctly the product signal should be constant and to obtain this condition the product signal is applied with a fixed voltage K2 to a difference circuit 21 which supplies via an integrator circuit 22 the controlling error voltage E. By connecting the unit 13 to the rails at the point braking is to commence and by providing the coils 16 at the end of the train, the frequency of the picked up signal can be directly related to the distance to go.

Title: Ohmic contact and method and composition for forming same
IPC: C04B35/468
Filed: 1971-06-16
Abstract: An ohmic contact 12 on a semi-conductor element 10 consists of a hypoeutectic alloy of Ni and In i.e. an alloy containing less In than is contained in the eutectic Ni/In alloy. The preferred In content of the contact 12 is 5-20% by weight. The device shown comprises a junction capacitor including a ceramic body 10 of barium titanate formed by pelletizing powdered material, firing in an oxidizing atmosphere at 2400 F. and heating at 1700-2300 F. in a reducing atmosphere to render it semi-conductive. Other semi-conductor materials mentioned are MnO, Fe 2 O 3 , Ga 2 O, NiO, Cu 2 O, TiO 2 , ZnFe 2 O 4 , SrTiO 3 , calcium or lead titanates and barium, magnesium or lead zirconates. The material may be intrinsic, N-type or P-type, and suitable dopants are La, Bi, B, In or Sb. The Ni and In for the ohmic contact 12 may be applied simultaneously or sequentially, the latter process being followed by firing to cause inter-diffusion. Vacuum deposition may be employed, or a Ni/In alloy may be ground, deposited as a powder and fired. The preferred process entails applying to the body 10 a mixture of finely divided reducible compounds of Ni and In e.g. oxides, carbonates or resinates in powder form or preferably dispersed in a matrix consisting of a film-forming vehicle, such as ethyl cellulose resin, and a slow-drying aromatic solvent, such as high b.pt. xylene. The mixture is painted or sprayed on and dried at 250-300 F. It is then fired at 1660-2000 F. in a reducing atmosphere to reduce the Ni and In compounds to elemental form. This process may be combined with the reduction of the ceramic body 10. The junction of the device is formed by applying a layer 16 of finely divided Ag in an inorganic binder of borosilicate frit and Bi 2 O 3 . On firing at 1700 F. it is considered that Bi diffuses into the body 10 to form a barrier layer 18. A further layer 14 of Bifree Ag may be formed on the ohmic contact 12 by applying an Ag or Ag 2 O dispersion in an organic resinous vehicle and firing.
