Title: Catalysts and preparation thereof
IPC: C07C29/145
Filed: 1966-12-15
Abstract: Hydrogenation and dehydrogenation reactions are effected in the presence of a Cu, Cr catalyst prepared by treating an aqueous Cu salt solution with an alkaline reagent to precipitate a copper compound, washing and drying the precipitate, impregnating it with a solution of an alkali metal chromate or dichromate and reducing the copper compound with hydrogen without previous calcination.  The reactions described include dehydrogenation of primary and secondary alcohols to aldehydes and ketones respectively and the reverse reaction as an example of the catalyst's hydrogenation power.  Further reactions described are hydrogenation of unsaturated aldehydes and ketones to the corresponding saturated alcohols e.g. furfural to furfuryl alcohol.  Examples describe (1) the dehydrogenation of ethanol principally to acetaldehyde but with the formation of small amounts of acetic acid, ethyl acetate, ether, acetone and methyl, ethyl ketone (2) the dehydrogenation of isopropanol to acetone in which a little mesityl oxide and ethane is formed; (4) n-butanol to n-butyraldehyde and small amounts of acid, ester and hydrocarbon; (5) the hydrogenation of 2-ethyl hexenal to 2-ethyl hexanol and a little 2-ethyl hexanal; (6) n-butanal to n-butanol almost quantitatively; (7) furfural to furfuryl alcohol; (8) dehydrogenation of C12- 14 alcohols to the corresponding carbonylic compounds; and (9) hydrogenation of mesityl oxide into methyl isobutyl carbinol.ALSO:Hydrogenation / dehydrogenation catalysts are made by treating an aqueous copper salt solution with an alkaline reagent to precipitate a copper compound, washing and drying the precipitate, impregnating it with a solution of an alkali metal chromate or dichromate and reducing the copper compound with hydrogen without previous calcination.  If desired the catalyst may be supported on Kieselguhr or SiO2 by inclusion thereof as a suspension in the intial copper salt solution.

Stitching 29 is used to secure the mesh-covering to the member 10 to assist in biologically fixing the prosthesis in place. Various prostheses may be made by having two V- shaped notches (Fig. 8 not shown) allowing flexure in forward and backward planes; alternatively, the angle between the arms of the V-shaped notch may be varied to give specific angles for flexure of the joint.

Abstract: 1374118 Altering physical structure REPUBLIC STEEL CORP 13 Dec 1971 [16 Dec 1970] 57729/71 Heading B3V A non austenitic steel, having a body centred cubic structure is rendered superplastic by rapidly heating it at a rate of at least 10‹ F./sec. to a temperature at which transformation occurs from b.c.c. iron at least partially to gamma iron, holding the steel at the elevated temperature to provide high ductility during an interval of microstructural instability and rapidly deforming the steel during the interval. A plain carbon steel containing less than 1 % C or a ferritic or martensitic stainless steel containing 11-27% Cr and 0-2À5% Ni, is heated by induction at less than 500‹ F./sec. from room temperature or a temperature below any transformation or the recrystallization temperature to a temperature above the A c1  point, peferably a temperature corresponding to a 50% alpha, 50% gamma structure. After holding the steel at this temperature for 5-10 sees., it is worked by coining, drawing, heading, pressing, stretching or upsetting at a strain rate of >1/min., preferably 100-1000/min., to produce an elongation of above 50%, e.g. 100% and 300%. The high ductility in the steel may be increased if it is cold rolled or forged, to produce a 50, 70 or 90% reduction in thickness, before the heating step. After the working step, the superplasticity disappears and the steel may be further worked by repeating the process. In an example, a 0À06% C steel is rapidly heated at 100-200‹ F./sec. to 1375-1550‹ F., preferably 1500‹ F., and a 0À2% C steel is heated to 1350-1450‹ F., preferably 1400‹ F.

If the bias at terminal 18<SP>1</SP> is altered positively or negatively, the duty cycle of the diodes 41, 42 is altered thereby altering the frequency towards one or other extreme.

Abstract: 1,249,540. Radar. GENERAL ELECTRIC CO. 22 Dec., 1969 [27 Dec., 1968], No. 62395/69. Heading H4D. To determine a component V X , Fig. 2 of the velocity V of a moving object, the doppler shifts imparted to two beams of radiation, incident on the object along position vectors E 1  and E 2  having an angle bisector orthogonal to V x , and scattered along a common direction E s1  are differenced, said difference being proportional to said velocity component. The measurement is independent of any movement of the object perpendicular to V x . Thus to detect the velocity of a metal sheet 10, Fig. 3, leaving a mill and liable to wrinkling (perpendicular movement), a laser 18 emits a coherent beam which is split into two beams 11 and 13 which intersect at a common point 15 on the sheet. The beams make equal angles 0/2 with the perpendicular to the sheet, so that V x  is the velocity of the sheet. The scattered radiation from the two beams is detected at 23 and therein mixed to produce the differential doppler frequency. Beam splitting semi-transparent and totally reflecting mirrors 22 and 24 may be incorporated in one solid optical block Fig. 4 having a semi-reflective face 30 and a totally internally reflecting back surface. As an alternative, a single beam of radiation 47, Fig. 5 may be incident on the sheet and the two differently scattered radiations detected by equally angularly offset means 48 and 52, 48 being a mirror and 52 being an optical mixer directing the combined radiation to the photodetector 54.
