Abstract: A heat machine comprising a displacer (1) reciprocating within a housing (4). The displacer incorporates first and second independent, co-axial, overlapping regenerators (12 and 14). A first working volume (8) is formed between the displacer (1) and the housing (4) at a hot end of the heat machine. Second and third working volumes (9 and 10) are formed between the displacer (1) and the housing (4) at a cold end of the heat machine. A partition (17) separates the second (9) and third (10) working volumes. A gas flow path exists from the first working volume (8) to the third working volume (10) via the first regenerator (12), the second working volume (9), a gas path within the partition (17), and the second regenerator (14).

Abstract: A multi-port microwave coupler has eight input ports In 1, In 2, In 3, In 4, In 5, In 6, In 7 and In 8 and eight output ports Out 1, Out 2, Out 3, Out 4, Out 5, Out 6, Out 7 and Out 8 and is synthesised from twelve 2 X 2 hybrid couplers which are arranged as three sets, that is a first set A, B, C and D, a second set E, F, G and H and a third set I, J, K and L. A first group of transmission lines 11, 12, 13, 14, 15, 16, 17 and 18 interconnect the first and second sets of hybrid couplers, and a second group of transmission lines 21, 22, 23, 24, 25, 26, 27, and 28 interconnect the second and third sets of hybrid couplers. The first set of hybrid couplers are arranged substantially in a row in the sequence first, second, fourth and third, that is A, B, D and C with one half of the second and third sets E, G, I and J arranged on one side of the row and with the other half of the second and third sets F, H, K and L on the other side of the row. In this manner all cross-overs in the first and second groups of transmission lines are avoided thereby providing a planar realisation of a 8 X 8 multi-port microwave coupler, Instead of the first set of hybrid couplers being arranged in a row, it is also possible to achieve a similar result by arranging the second set of hybrid couplers in a row in the same sequence. The invention is of application to higher order n x n multi-port microwave couplers where n = 2 (2+p)  and p is a whole number.

Abstract: The proposal is for a process and device for making moulded parts (11), especially concrete shaft sections. The parts are shaped in a mould consisting of a core (15), a casing (20) and a lower sleeve (24) into which the moulding compound is poured and compressed by vibration. During production, in shaping from the moulding compound, at least one support (25 to 28) on which a foot may be placed is formed from inside in the shape of a recess (30 to 33), for which purpose the core (15) has one mould body (55 to 58) per recess (30 to 33) to be formed with a shape corresponding to that of the recess. After this shaping process the finished moulding (11) is removed from the mould before the binder has set inn the concrete.

Abstract: A fat composition for cosmetic or pharmaceutical emulsion products, substantially consisting of a mixture of mono-, di- and triglycerides, wherein more than 90 weight % of the fatty acid residues incorporated in the glycerides contain 16-22 carbon atoms, produced from vegetable fats. The fat composition consists of a glyceride system A which is a mixture of mono-, di- and triglycerides having the composition 10-50 weight % of monoglyceride, 25-55 weight % of diglyceride and more than 10 weight % of triglyceride and having a hydroxyl number of 90-190 and an iodine number of 40-90, produced from unhardened or hardened vegetable fats or fractions thereof, preferably admixed with up to the same weight amount of a glyceride system B which is a mixture of mono-, di- and triglycerides having the composition 5-20 weight % of monoglyceride, 40-60 weight % of diglyceride and 20-50 weight % of triglyceride and having a hydroxyl number of 50-190 and an iodine number below 30, produced from hardened vegetable oils or fractions thereof. Hereby it is achieved that the fat composition serves both as an emollient, a stabilizer consistency imparting agent and coemulsifier in the emulsion product and that the consistency of the emulsion can be adjusted by varying the mixture proportion between the two glyceride systems in the fat composition.
