Title: Method of preparing hydroperoxides of alkyl-substituted aromatic hydrocarbons
IPC: C07C409/10
Filed: 1964-05-01
Abstract: As a promoter in the manufacture of hydroperoxides from alkyl-substituted aromatic hydrocarbons by treating the hydrocarbons with an oxygen-containing gas, use is made of magnesium oxide or potassium oxide or of either of these oxides in combined form with an acid-acting refractory metal oxide, a term which is defined as including silica and boria.  The proportion of magnesium or potassium in a promoter containing a refractory metal oxide is about 5-20%. Specified hydrocarbons which may be treated include ethyl-, propyl-, butyl-, isobutyl- and isoamyl-benzenes, 1-ethylnaphthalene, 9-ethylanthracene and 1-ethylphenanthrene, but the process is particularly applicable to aromatic hydrocarbons having a tertiary carbon atom in an a -position to the aromatic nucleus, e.g. 2-isopropyl-naphthalene, 1,1-diphenylethane, cumene, p-cymene, p-diisopropylbenzene and p-t-butylisopropylbenzene. Besides silica and boria, specified refractory metal oxides with which the magnesium or potassium oxide may be combined are bauxite, kaolin, bentonite, kieselguhr, montmorillonite, magnesia spinels, zinc oxide spinels, alumina, thoria, titania, zirconia and composite of silica-alumina, silica-zirconia or alumina-boria.  The reaction may be effected batchwise or continuously at about 50-130 DEG  C. under atmospheric or slightly reduced pressure or at a raised pressure up to about 34 atm.  The reactions may be further promoted by including in the initial reaction mixture a small proportion of the hydroperoxide which is to be produced in the process.  Examples are given of the manufacture of cumene hydroperoxide with the aid of magnesium oxide and of promoters prepared by impregnating alumina or silica-alumina with potassium nitrate solution, drying, and calcining at 550 DEG  C.

Abstract: 792,529. Unattended repeaters. COMPAGNIE GENERALE D'ELECTRICITE. June 15, 1956, No. 18527/56. Class 40 (4). In a telephone transmission system including a series of unattended repeaters 9 to which power is fed over the transmission line 10, the repeaters which include a chain of series connected valve filaments 5 have a highly selective resonator 13, a rectifier 14 and a low-pass filter 15 connecting the output of the amplifier 1 to the input end of the filaments 5 so that a frequency modulated test signal from a generator 12 at a terminal station is returned as a current of low frequency of the order of tens of cycles for display on an element such as an oscilloscope 16 so that the returning levels may be observed for test purposes. The application of the invention to two-way repeaters is described with reference to Fig. 6 (not shown). The duration of the frequency modulated signal does not exceed a few hundred cycles per second and the rhythm of deviation is of the order of a few cycles per second. The resonators 13 are tuned to a different frequency in each repeater. In an alternative testing arrangement the frequency sweep is made to cover all the resonators and a sequence of peaks returned after different time intervals is observed. Specification 446,225 is referred to.

Abstract: 848,539. Moulding battery separator plates. MASSE, T. G. June 1, 1959 [July 21, 1958], No. 18591/59. Class 87(2). [Also in Group XXXVI] A free-running, thermoplastic, and thermoshrinking powder is deposited upon an unheated metal plate and screeded to form a layer of uniform thickness, the plate heated from below to a temperature sufficient to cause the powder particles in contact with it to adhere to it, the plate further heated from below to raise its temperature sufficiently to commence mutual adhesion by fusion of those particles in the lower portion of the powder layer, the layer heated from above to complete the mutual adhesion of all the particles and also to shrink them and consequently the layer which they form to produce a microporous strip, and the strip removed after cooling and cut into separator plates of the required size. A suitable powder is obtained by separating the small particles of emulsion polymerised polyvinyl chloride from the water of the emulsion by spraying through an atomiser into a hot oven at a temperature above the fusion point of the particles, e.g. 225F. Copolymers of vinyl chloride with vinyl acetate or vinylidene chloride may be used in place of polyvinyl chloride. If the powder does not include a heatresistant wetting agent, the finished separator plates should each be immersed in a wetting agent. In the apparatus illustrated, the powder 6 is deposited by the vibrating hopper 8 onto a metal conveyer belt 9 and conveyed to the screeding device 4 which comprises a series of laterally moving blades 17 carried by the chain 16 which passes round the rotating sprockets 15, Fig. 3. The powder is then conveyed between the support roller 25 and a profiling roller 5, after which it is heated from below by gas burners 31 and from above by radiant heaters 32, finally being cooled from below by idler rollers 34 partially immersed in cold water and from above by cold air jets from an air duct 36.

Filed: 1939-06-27
Abstract: 530,503. Testing balance of rotary apparatus. AVERY, Ltd., W. & T. (Schenck Eisengiesserei und Maschinenfabrik Darmstadt, Ges., C.). June 27, 1939, No. 18617. [Class 106 (ii)] Means for determining and indicating the magnitude of the compensating weight comprising a pointer to which a variable leverage setting is given, determined by the ratio between the movement of the compensating force and the unbalanced force at its plane of correction the pointer being moved through an angle governed by the longitudinal traverse of the rotatable counter-balancing weight relative to a lever arm whereby a direct indication is afforded of the compensating weight required. The invention is applied to a wellknown form of balancing machine shown in Fig. 1 in which the spindle 6a of the rotor to be balanced is mounted at one end in a fulcrum bearing 7 and at the other end in a resilient bearing 8 connected to a bearing 9 at one end of a lever shaft 10 fulcrummed at 10a. On the shaft 10 is slidable a disc 11 carrying an eccentric weight G which can be adjusted angularly of the disc relative to the unbalanced part u of the rotor 6. Adapted to be indirectly connected to the disc G and traversable therewith is a slide 12, Fig. 2, which carries an upwardly extending guide rod 12a pivotally associated with a pointer 14 pivoted at 14a. The pointer has a longitudinal slot adapted to receive a pin 17a projecting from a member 17 which is provided with a cruciform slot to accommodate the guide rod 12a and a second guide rod 16b having a sleeve 16 an index on which slides over a scale S. A graduated chart attached to the frame of the machine is provided with the scales S, S<SP>1</SP> which indicate lever ratio and counterbalancing force respectively, while a third scale 15 indicates the correction required in the pre-determined plane of the rotor. The sleeve 16 is set prior to a test and the setting depends upon the position of the correction plane in relation to the supporting planes or bearings of the rotor. This is obtained by a diagonal chord and graduated scale. Various modifications of arrangements of scales and pointers are described.
