IPC: B62D55/13
Filed: 1975-05-02
Abstract: 1481885 Endless-track vehicles DEERE & CO 2 May 1975 [2 May 1974] 18377/75 Heading B7H In an endless-track tractor having track drive sprockets 70, 72 carried by output shafts 62, 64 of final drive transmission units 50, 52 coupled by input shafts 54, 56 to a main transmission, the housings 58, 60 of the final drive units are secured to the main transmission housing 44 by bolts which are arranged so that the final drive units can be mounted with the axis Y of the output shafts 62, 64 in either of two positions displaced relative to one another longitudinally of the tractor. The sprockets 70, 72 can thus be located in a rearward position when the tractor is equipped with a dozer blade and in a forward position when it carries a loader bucket. Each final drive housing 58, 60 has a flange 84 through which bolts 82 extend into threaded holes in the main transmission housing 44, and threaded holes 86 in the final drive housing receive further bolts which extend through the main transmission housing 44 from the inside. The bolts are arranged in a generally rectangular pattern which is symmetrically disposed about a vertical plane containing the input shaft X so that the output shaft axis Y is in a rearward position when the final drive units 50, 52 are mounted on the right and left sides of the housing 44 respectively and in a forward position when the units 50, 52 are swapped to the left and right sides. The bolts may alternatively be pitched regularly around a circle centred on the input shaft axis X so that each final drive unit can be fixed to the main transmission housing in either of two positions displaced from each other rotationally about the axis X.

Patent GB-810448-A (GB)
Title: Methods of and apparatus for treating solid-liquid systems
IPC: C22B4/00
Filed: 1956-06-15
Abstract: 810,448. Zone melting; alloys. WESTERN ELECTRIC CO. Inc. June 15, 1956 [June 17 1955], No. 18591/56. Class 82(1) [Also in Group XXXV] , In a method of treating a body of material in which a portion of the body is liquid and wets an adjacent solid portion of the body, the liquid portion being subjected to a force tending to displace it from a desired position, an electric current is passed through at least the liquid portion and a magnetic field is impressed across this portion so that the electric current and magnetic field co-act to provide a sustaining force which opposes the said displacing force. The method may be applied in zonemelting particularly of semi-conductor materials such as silicon or germanium, in alloying processes by adding a solid or gaseous addition agent to the molten portion or in refining by evaporation of a volatile constituent or reaction of an impurity in the melt with an agent in the surrounding atmosphere. Fig. 2B illustrates the application of the method to a zone melting process, the rod 10, enclosed in quartz tube 11, is clamped at its ends in supports 12 and 13. Electric current is passed along the rod and a magnetic field is set up between magnet faces of opposite polarity, one 25 being shown. Coaction of the current and field produces an upward force which counteracts the effect of gravity on the molten zone 27 produced by induction heater 28. Any suitable atmosphere or a vacuum may be maintained in tube 11 by means of inlet and outlets 19 and 20. The invention may be used for fusing and solidifying in rod form a sintered body or, as shown in Fig. 6, for melting and solidifying in rod form a powdered material. In the latter application a rod 123 is clamped at one end in support 121 the other end being clamped in a moveable support 120 which is moved to the left as powdered material is added from hopper 134 to the molten zone 128. The pole faces of the magnets may be suitably shaped to provide a more uniform field in the region of the molten portion or to provide a graded field decreasing an intensity in the upward direction to improve the stability of the molten zone. A non-uniform magnetic field may also be used to modify the configuration of the molten portion. Specification 769,673 is referred to.

Patent GB-421196-A (GB)
Title: Improvements in the manufacture and production of amines
IPC: C07D215/06
Filed: 1933-07-03
Abstract: Amides of aliphatic carboxylic acids containing at least eight carbon atoms are converted into amines by catalytic hydrogenation at a temperature of at least 200 DEG  C. and a pressure above 50 atm. The amides treated may be simple amides or may be substituted on the nitrogen atom with aliphatic, cycloaliphatic or aromatic radicles; in this connection reference is made to the treatment of the acid anilides or their N-mono- and -di-methyl, -ethyl and -butyl amides and N-monocyclohexylamides; when anilides and like arylamides are treated, simultaneous hydrogenation of the aryl nucleus may occur. The process may also be applied to amides derived from the acids and secondary heterocyclic amines, e.g., to N-laurylpiperidine, N-lauryltetrahydroquinoline, or N-oleylpiperidine.  Mixtures of amides may also be treated, e.g., amides of naturally occurring acid mixtures or of acids obtained by oxidizing higher paraffin hydrocarbons.  In the examples, (1) lauric amide is converted into mono- and di-dodecylamine in the presence of a catalyst prepared by precipitating aluminium and cobalt together from solution by means of sodium bicarbonate, and heating the precipitate in air; (2) lauric acid dimethylamide is converted into dimethyldodecylamine in the presence of a catalyst prepared by adding sodium bicarbonate to a solution of copper and manganese nitrates containing bleaching earth, and heating the precipitate; (3) stearic acid methylamide is converted into methyloctodecylamine in the presence of a nickel catalyst activated with chromium; the methylamides of carboxylic acids obtained by oxidizing higher paraffin hydrocarbons may be treated similarly; (4) amides of cocoanut oil acids are converted into amines in the presence of a catalyst prepared by heating precipitated cobalt carbonate; (5) caprylic anilide is converted into N-octyl-aniline in the presence of the catalyst used in example 2; if the catalyst described in example 3 is used, octylcyclohexylamine is obtained; (6) N-lauryl-1 : 2 : 3 : 4-tetrahydroquinoline is converted into N-dodecyl-1 : 2 : 3 : 4 p  - tetrahydroquinoline in the presence of the catalyst used in example 4.ALSO:In a process for the conversion of amides of aliphatic carboxylic acids containing at least eight carbon atoms into amines by catalytic hydrogenation, use is made of catalysts prepared (1) by precipitating aluminium and cobalt together from solution by means of sodium bicarbonate, and heating the precipitate in air; (2) by adding sodium bicarbonate to a solution of copper and magnesium nitrates containing bleaching earth, and heating the precipitate; (3) by heating precipitated cobalt carbonate.  The use of a nickel catalyst activated with chromium is also described.

Abstract: A process for zone-melting germanium or silicon by the passage of a molten zone having a very small dimension (up to 0.01 in.) in the traverse direction which comprises forming in a body of the germanium or silicon a molten gold alloy zone and effecting passage of the zone through the body by the simultaneous passage of a direct electric current.  The gold may contain arsenic, boron, or gallium to effect doping of the body.  The zone may be formed by heating the body in a furnace or by direct electrical means.  The zone may extend substantially right across the body to effect recrystallization of the whole body (Fig. 1, not shown), be a thin wire forming a recrystalized thin sheet within the body, or be a small sphere forming a recrystallized thin wire within the body.
