Title: Preparation of mesityl oxide and/or methyl isobutyl ketone
Inventor: SIROIS LIONEL JAMES
IPC: C07C45/74
Filed: 1966-06-24
Abstract: Mesityl oxide is prepared by continuously contacting an oxygenated hydrocarbon feed, which contains acetone, in the gas phase in a condensation zone with a catalyst consisting mainly of zinc oxide at a temperature of about 400 DEG  to 800 DEG F., continuously withdrawing a product stream containing mesityl oxide from the condensation zone, cooling the product stream below 120 DEG  F., separating a vaporous fraction containing substantial amounts of hydrogen, propylene and acetone and minor amounts of isopropanol, water, methylisobutyl ketone and mesityl oxide from a liquid fraction containing the remainder of the unreacted feed and reaction products, distilling this liquid fraction to recover a fraction rich in unreacted feed and a mesityl oxide-rich fraction, and recycling part of the vaporous fraction and unreacted-feed fraction to the condensation zone in such amounts that the recycled mesityl oxide does not exceed 0.5 mol. per cent of the total feed to the condensation zone.  A preferred embodiment involves contacting the mesityl oxide-rich fraction with hydrogen in the presence of a hydrogenation catalyst, suitably nickel, to convert mesityl oxide to methyl isobutyl ketone, fractionating the effluent from the hydrogenation zone to separate methyl isobutyl carbinol, and recycling the methyl isobutyl carbinol and part of the vaporous fraction and unreacted feed fraction to the condensation zone under the same conditions with respect to molar percentage of mesityl oxide recycled.  Products can be withdrawn at various stages of the process and can consist essentially of mesityl oxide, methyl isobutyl ketone or methyl isobutyl carbinol. The catalyst for the main reaction in the condensation zone is preferably 70-99% by weight of zinc oxide with 1-30% of a promoter which can be cerium, thorium or zirconium oxide. Preferred conditions in the condensation involve contacting acetone with the catalyst at a space velocity of 0.25 to 2 volumes of total feed per volume of catalyst per hour, in admixture with 0.01 to 1 mol. (or better, 0.01-0.04 mol.) of hydrogen per mol. of acetone at a temperature between 500 DEG  and 800 DEG  F. and pressure of 5 to 75 p.s.i.g. such that the conversion level of acetone to mesityl oxide is between 7 and 12%, wherein the vaporous fraction of the feed contains less than 0.3 mol. per cent of recycled mesityl oxide and the acetone-rich fraction not more than 0.2 mol. per cent of mesityl oxide.

Title: Improvements in or relating to pressure exchangers
Inventor: BROWN JAMES
IPC: F04F13/00
Filed: 1966-06-28
Abstract: 1,144,262. Pressure exchangers. POWER JETS (RESEARCH & DEVELOPMENT) Ltd. June 28, 1967 [June 28, 1966], No.28926/66. Heading F1N. In a pressure exchanger comprising a cell ring 5, 6, 7 rotatable between end-plates 2, 3 having outlet ports 11, 16 and inlet ports 12, 17, the end-plate 3 is enclosed in a casing 25, 4, 26 through which extends a low-pressure outlet duct 21 having a flared end 22 spaced inwardly from the peripheral surface of the outlet port 16 to provide an inlet passage to the casing 4, 25, 26 for gases leaking from the cell ring between the ring and the endplates 2, 3. The pressure of the gases in the casing 4, 25, 26 act on the end-plate 3 and thereby tend to balance the pressure of the gases in the cells. Leakage gas also flows out over the inner surfaces of the outlet duct 21 to provide a cooling film which does hot disturb the smooth flow of low-pressure gas passing therethrough. The cell ring has stub shafts 8 supported for rotation in bearings 9 mounted in housings 10 fixed to the end-plates 2, 3. Each bearing maintains constant clearance between its end-plate and the adjacent end of the cell ring. Sleeves 23, 27 fixed to the end-plate 3 are slidably mounted in the annular casing parts 25, 26 to allow for expansion of the cell ring. A double walled high-pressure inlet duct 19, 20 slidably extends through the casing part 26 and is secured to a plate 18 forming part of the end-plate 3. The casing may be extended to enclose one or both of the ducts 20, 21. The end-plate 3 may slide in the cylindrical casing part 4 so that the sleeve 23 may be omitted.

Title: Radio telephone station
IPC: H04W88/02
Filed: 1967-06-23
Abstract: 1,129,237. Radio signalling; frequency discrimination. INTERNATIONAL STANDARD ELECTRIC CORP. 23 June, 1967 [30 June, 1966], No. 29113/67. Headings H3A and H4L. In a radio telephone station 10, Fig. 3, for single-sideband working, signals received on a receiving path 12 from an aerial 11 are diverted during waiting periods by a switch 20, having a contact 20a, to a detection circuit 15. The output 18 of the detection circuit 15 is connected by a line 19 to a signalling device 17 which is operated when a spoken message is received instead of random noise. The detection circuit 15 utilizes the change of the mean frequency of the passages through zero of the received wave from a value corresponding approximately to the centre of the pass-band with noise, to a lower value with speech. As described, the demodulated received signals are fed to the input terminal 16, Fig. 4, of a four-stage squaring amplifier comprising transistors Q 1 -Q 4 . The output side of the first stage includes a by-pass capacitor C A , and the output 22 from the fourth stage consists of rectangular waves of constant amplitude (Fig. 5(a), not shown). These are differentiated by a capacitor C B  and a resistor R B  and are then rectified by a transistor Q 5 , the output 24 of which consists of negative-going impulses of constant amplitude and duration, spaced apart at intervals corresponding to the passages through zero of the received signals (Fig. 5 (b), not shown). The impulses are applied to an integrating circuit comprising a resistor R C  and a capacitor C C . The potential at the point 25 has a maximum positive value in the absence of impulses, which is reduced to a minimum value when random noise is being received, and to an intermediate value when speech is being received. This potential is applied to a two-stage amplifier comprising transistors Q 6 , Q 7 . Adjustable bias is provided by means of potentiometers RD, RF, and a capacitor C E  across the output of the first stage slows down variations in the current, in order to provide cover for silent intervals in the spoken calling message. The rise in potential at the output 28 of the transistor Q, with speech (Fig. 5(c), not shown) controls an output transistor Q 8  having a signal relay S in its collector circuit. A contact 9 of the relay S operates the signalling device.
