Filed: 1964-09-22
Abstract: <PICT:1076814/C6-C7/1> A device for adjusting the position of a specimen carrier 1, which is freely rotatable about two axes A, C arranged in perpendicular relation to each other and is located within a treatment chamber, e.g. for vaporising objects in high vacuum for the purpose of preparing specimens for electron microscopy as well as for the production of metallic or non-metallic coatings or other layers, comprises two individually rotatable driving shafts, 5', 6' arranged in concentrical relation to each other and extending through the wall of the chamber, the rotation of the specimen carrier about its two axes of rotation being derived from the driving shafts. The specimen carrier is additionally orientable about a third axis B arranged in perpendicular relation to one or the other two axes, thus allowing it to be elastically pressed against a cooling body provided in the treatment chamber. The specimen carrier is held in a gimbal suspension and rotated by bevel gears.  In an alternative embodiment, rotation of the specimen carrier about the third axis is obtained by sliding one shaft relative to another.

The preferred compounds are those in which X and X1, are chlorine, bromine, iodine, benzenesulphonyloxy or p-toluenesulphonyloxy.  At least 4 moles of ammonia per mole of starting material is used, the total pressure in the reactor being within the range of 50 to 3,000 atmospheres. Reaction times vary from 30 minutes to 30 hours.  A nonhydroxylic liquid reaction medium can be used. Detailed examples are given and suitable starting materials listed. 1,4-Dichloro-2-alkyl-bicyclo [2.2.2]octane is made by reacting 1,2,3,4-tetrachlorocyclohexa-1,3-diene (from chlorocoumaline and ethylene) with the appropriate alkene to give a 1,2,3,4-tetrachloro-5-alkyl-bicyclo[2.2.2]-hoct-ene and hydrogenating this to the octane. 1,4-dihydroxy-2-alkyl-bicyclo[2.2.2]-octanes are made by hydrolysis of the 1,4-dichloro compound with water in the presence of a copper oxide-iron metal catalyst at 200 DEG C. Esterification of the hydroxyl groups gives esters and reaction with a hydrohalic acid the corresponding halide. 1,3-dihalo-5-alkyl-tricyclo[3.3.1.13,7]decanes are made by converting the known 1,3,5-tribromotricyclo[3.3.1.13,7]decanes to the Grignard reagent followed by reaction with an acid chloride and reduction of the ketone so formed to the hydrocarbon.  The 5-aryl derivatives of the 1,3-dihalotricyclo-[3.3.1.13,7]decanes from the 1,3,5-tribromo compound by Friedel Crafts reaction with an aromatic compound and aluminium bromide. 1,4-Dinitrato-bicyclo[2.2.2]octane is made from 1,4-diiodobicyclo[2.2.2]octane and silver nitrate. 1,3-dinitrato-tricyclo[3.3.1.13,7]-decane is similarly made from the 1,3-dibromo compound.  Other groups X and X1 are introduced by reaction of the appropriate dihydroxy compound with appropriate acid halides or anhydrides such as chlorosulphonic acid, dibenzylphosphorochloridate (followed by catalytic hydrogenation to remove benzyl groups), perchloryl fluoride, benzoyl chloride, butanesulphonyl chloride, benzenesulphonyl chloride, or trifluoroacetic anhydride.

Apparatus for cutting lengths of clay, preferably from an extruder comprises a device which rotates the clay lengths through 90 degrees about a vertical axis and passes the rotated lengths through a multiple cutter and on to a series of rollers provided with spacers. Billets of clay are fed on to driven rollers 1, actuate trip 4 and pass on to partially grooved rollers 5 situated over frame 7. Frame 7 carrying the clay is lifted clear of the rollers, rotates through 90 degrees to the position shown dotted, and is lowered back to below the level of rollers 5.

[Also in Division H1 Semi-conductor chips initially contained within magazines 48a, b, c on a rotatably indexable turret 46 are transferred individually to radially reciprocable needles 43 carried by a rotatably indexable needle carrier 42 which transports them to and deposits them on a substrate S. Different types of transistor chip may be carried around the peripheries of the various magazines 48a, b, c, which are individually rotatably indexable, for selective positioning on and subsequent sonic bonding to a ceramic substrate S carrying a preformed circuit. In the embodiment the needles 43 are hollow and retain the chips by means of suction. A sticky substance on the substrate S causes the positioned chips to be retained thereon despite the suction in the needle 43. The substrate supporting table 40 is movable horizontally so that after placement of each chip the substrate S may be repositioned beneath a sonic bonding head. Selection and indexing of the magazines 48a, b, c, indexing of the needle carrier 42, and reciprocation of the needles 43 at pick-up, alignment and placement stations, as well as axial rotation of the needles 43 carrying the chips to orientate them correctly relative to the substrate S, are effected in timed relationship by a programmed control circuit and a system of cams. A missing chip detection device 55 based on a vacuum sensitive switch is incorporated in the chip alignment device 54, and further means are provided for indicating when the magazines 48a, b, c are almost empty.
