Title: Process for the production of alpha, beta unsaturated carbonyl compounds
IPC: B01J23/28
Filed: 1962-11-07
Abstract: Alpha, beta-unsaturated carbonyl compounds are prepared by contacting a liquid feed containg a monofunctional, aliphatic C2 to C20 aldehyde and/or ketone having at least two alpha hydrogen atoms at from 50 DEG to 600 DEG  C. with a catalyst produced by reacting together at elevated temperature the trioxide of molybdenum and an oxide of magnesium or other compounds of these metals which produce these oxides at the elevated temperature.  The catalyst may be utilized alone or in combination with a support or carrier, e.g. alumina, and, in a modified process, may also contain zinc oxide. In a further modification, the feed also comprises a monofunctional, aliphatic aldehyde or ketone, e.g. formaldehyde.ALSO:An amorphous spinel-type material is obtained by reacting together at an elevated temperature, generally 300 DEG  to 1500 DEG  F., the trioxide of molybdenium and an oxide of magnesium or other compounds of these metals which produce these oxides at the elevated temperature.  If zinc oxide or a compound which produces zinc oxide at the elevated temperature is present the zinc oxide is physically entrapped in the spinel product formed. In an example, a spinel-type product is obtained by dry-mixing equimolar amounts of ammonium molybdate and magnesium oxide in powder form, adding water to form a paste, drying said paste at 400 DEG  F. for 16 hours, pilling the crushed and ground product and finally calcining the pills at 1100 DEG  F. for 16 hours. Similar processes for the preparation of zinc oxide containing products are also described.ALSO:A catalyst is prepared by reacting together at an elevated temperature, generally 300-1500  DEG F., the trioxide of molybdenum, an oxide of magnesium and zinc oxide or other compounds of these metals which produce these oxides at the elevated temperature. The catalyst may be utilized above or in combination with a support or carrier, especially alumina.  In the examples, the catalyst is produced by (A) dry-mixing equimolar amounts of MoO3, MgO and ZnO in powder form, adding water to form a paste, drying said paste at 300  DEG F., pilling the crushed and ground product and calcining the pills at 1100  DEG F. for 16 hours, and (B) calcining alumina at 1000  DEG F. for 16 hours, impregnating the alumina with ammonium molybdate solution, drying the impregnated alumina at 250 DEG F. prior to calcining at 1000  DEG F. for 16 hours, impregnating the calcined product with magnesium nitrate solution, drying at 250 DEG F. prior to calcining at 850  DEG F. overnight, impregnating this calcined product with zinc nitrate solution, drying at 250  DEG F. and finally calcining the impregnated material at 850  DEG F. overnight.

Abstract: 1285685 Transistor amplifying circuits MARCONI CO Ltd 24 May 1971 [3 Sept 1970] 42207/70 Heading H3T In a transistor amplifier including at least one transistor which in operation produces at least the third harmonic of a fundamental frequency applied to the input terminal of the amplifier, voltage limiting means are provided for modifying the phase of at least the third harmonic frequency component of voltage present at the collector of said transistor in relation to the fundamental frequency component of voltage there present substantially without changing the amplitude of said fundamental frequency component whereby the application of excessive voltage to said transistor as a result of third harmonic generation thereby is prevented. Transistors 1, 2 operate in class AB, being driven with high frequency from a transformer 3; the output is taken via transformer 4, a line 6 and a filter 5 tuned to reject third harmonic. Limiting diodes 9, 10 are connected to the collectors of transistors 1, 2 respectively, with their common terminal connected to a biasing terminal 12 and via capacitor 11 to earth. the arrangement is such that the diodes do not clip the fundamental frequency, but only the harmonics which have become phase-shifted by the line 6 and filter 8. The effect of limiting is to shift the phase of the third harmonic.

Single sideband outputs are obtained by adding or subtracting the two quadrature phase outputs k sin pt sin (wt+#) and k cos pt sin (wt+#) obtained from a modulator as described in Specification 895,304, after one has been phase shifted by 90 degrees. In this modulator two pairs of capacitors of a bridge are varied in opposite senses by a modulating source, and each pair are at 90 degrees phase relation to the other. The modulator outputs may be combined without interaction through coaxial lines differing in length by #/4 connected to a coaxial line bridge formed of three equal lengths BF, BG, FD, e.g. .15#. in length, and a fourth arm longer than the others by #/2. Across load resistors R equal to the characteristic impedance of the coaxial line are then developed at F, G upper and lower single sidebands. One single sideband may be used in the radio direction finder using a sequentially switched set of antennae and an omnidirectional aerial, as described in Specification 695,085.

Abstract: 1,182,290. Tape recorders. STAAR S.A. 19 Sept., 1967 [27 June, 1967], No. 42619/67. Heading G6B. Edgewise insertion of a cassette 3 causes a plate 2 to move with the cassette and towards it so that capstans 10, 10<SP>1</SP> and spindles 6, 7 enter the cassette, generally as described in Specification 1,080,082, and a pin 15 carried by the plate 2 moves, through levers 23, 25, 26, a slider 36 to the position shown in Fig. 1A in which capstan 10, spindle 6, and pinch roller 11, Fig. 1, are operative and the tape 4 is driven in the first direction F; when cessation of tape movement is detected by a device 76, which may be of the kind described in Specification 1,122,041, a solenoid 32 is briefly energized to release the lever 23 from the retaining action of pin 15 so that a spring 54 urges the slider 36 to its opposite extreme position (Figs. 2 and 2A) in which capstan 10<SP>1</SP>, spindle 7, and pinch roller 11<SP>1</SP> are operative and the tape 4 is driven in the reverse direction (F1).

Title: Semiconductor device and method of making the same
IPC: H01L23/498
Filed: 1962-11-16
Abstract: 1,016,343. Semi-conductor devices. HUGHES AIRCRAFT CO. Nov. 16, 1962 [Dec. 5, 1961], No. 43433/62. Heading H1K. A semi-conductor element is bonded to a layer of conductive material provided on an area of a ceramic body. Surface diffusion of an N-type dopant into a high resistivity germanium layer 12 (Fig. 3), epitaxially formed on a P + germanium crystal 11, produces a layer 13. The body is then sliced forming bars 10 which are subsequently etched to expose a region 14 of original crystal. A relief pattern of mesas is formed on a disc 15 (Fig. 4, not shown) of unfired alumina by, for example, ultrasonic drilling and the disc is subsequently fired to harden the material. Protruding structures 17, 18 and 21 which form collector base and emitter conductor supports respectively, and the disc perimeter surface 34 (Fig. 8, not shown) are plated with a molybdenum-manganese coating followed by layers of copper and nickel by electrolytic or electroless plating methods. Electrolytic plating of lead-antimony 51 on to arms 18 of the base support and arm 21 of the emitter support followed by gallium or lead gallium 52 on emitter support 21 and on collector support 17 provides the necessary dopant materials. Tantalum leads 27, 28 and 29 are then bonded to their respective supports in a heating process which produces a nickel-copper bonding alloy on the molybdenum-manganese surface. In an alternative method the metallisation steps precede shaping of the disc. The bar 10 of Fig. 3 is then placed on the completed disc of Fig. 8 so that regions 13, 18 and 21 are in contact as are regions 14 and 17. After etching and cleaning steps the assembly is then heated to fuse the parts together and the PNP transistor so formed may be encapsulated in a metal or ceramic hermetically sealed housing (Figs. 10 and 11, not shown). In a variation of the production method, surface diffusion of antimony into a P-type germanium crystal produces an N-type surface region and with a back-strap ohmically bonded thereto a doubledoped alloy is alloyed to the N-type surface to produce a P-type emitter region with an underlying diffused base region.
