Abstract: 1390800 Laying pipes GRANGES ESSEM AB 19 Oct 1972 [21 Oct 1971] 48222/72 Heading F2P In a method of laying pipes underground, for example to supply a hot fluid to houses 13, 14, 15 from a central heat-generating plant, the pipes are layed in a trench 54 and are bent into wave shaped loops to relieve expansion stresses. The pipes have a heat insulating jacket within which the pipes can move transversely. As shown in Fig. 1, a heat supply system may comprise main pipes 16, 17 to which branch pipes 21, 20 are connected and from which individual houses 13, 14, 15 are supplied. In an alternative configuration, a group of houses are supplied from a distribution point (40) (Fig. 2, not shown) connected to main pipes 16, 17 by further pipes (38, 39). As shown in Fig. 6, the pipes 55, 56 may be layed in a straight, broad trench 54 around guides 57. The wave-shaped loops may alternatively lie in a vertical plane with the guides 57 placed on the side walls 58, 59 of the trench. In another arrangement, a narrower trench is dug in wave-shaped loops and the pipes are layed to follow these loops (Fig. 5, not shown). The pipes are preferably layed in long, continuous lengths and comprise a metal inner pipe (51) (Fig. 3, not shown) encircled by a soft and elastic insulating layer (52) enclosed by a plastics layer (53).

Filed: 1963-12-06
Abstract: 1,076,201. Burning refuse. J. WOTSCHKE. Dec. 6, 1963, No. 48388/63. Heading F4B. Refuse is fed down an annular shaft 11 to form a funnel-shaped free surface 3 to which heat is supplied from a burner 5 mounted in an arched roof member 7. Slag, and some of the combustion gases are taken off from the bottom of the funnel through an outlet 2, the remainder of the combustion gases passing upwards through the shaft 11 to dry and preheat the refuse. Gases from the top of the shaft 11 and the gases 20 from the outlet 2 are burned in a secondary combustion chamber 18. Air supplies L1-L5 are directed to the burner, as secondary air supplies through the roof 7, to the refuse in the shaft 11 and to the secondary combustion chamber 18. Water seals 14, 15, 24, 25 permit the rotation of the casing 6, which has projections 22 for agitating the material. In another embodiment (Fig. 4, not shown), liquid waste flows over the edge of a flange forming a cup surrounding the roof member to form a film over the funnel-shaped furnace body. The slag is collected in a rotating receptacle below the furnace and is granulated by centrifugal action.

Abstract: 1,070,984. Feeding bottles. PET MILK CO. Dec. 10, 1963 [Jan. 4, 1963], No. 48682/63. Heading A5X. [Also in Division B8] A feeding teat and an attachment ring are supplied in a sterilised package for attachment to the end of a container holding pre-packed food. The container is preferably a sealed, cylindrical tin and the retaining ring is of such a shape as to hold the teat on to one end of it. The teat 11, Fig. 2, is formed with the usual bulbous end 32 and, at the other end, has a reduced neck 36 between a flange 35 and a rounded portion 34. This neck is engaged by the rolled-over edge 41, Fig. 3, of a central aperture in the attachment member 12 and this is provided with a depending lip 43 carrying, internally, a continuous rib 44 and a number of inwardly directed projections 45. For storage, the assembly of the teat and attachment ring is sterilised and sealed in an easily ruptured cover, made of transparent plastic material such as polypropylene, and formed as a conical upper portion (54) sealed around its free edges to a disc-shaped lower portion (55). The outer surface of the tin of food is then sterilised and the nipple assembly is partially forced over its end and retained by shrinking a cellulose band around it. When the contents are required for use the nipple assembly is removed from the tin and taken from its protective cover, the tin (53), Fig. 9, is punctured with a can-opener, at (63), and the retaining ring, together with the teat, is pressed down on to the tin until its internal rib 44 engages behind the rim (59) on the tin. The attachment ring is preferably made of transparent or translucent material so that it can carry graduation marks which will indicate the residual contents of the tin when the latter is laid in a horizontal position. In a modified form the lower flange portion 35 is made sufficiently wide to lie under an orifice in the attachment ring member so as to act as a non-return valve and admit air to the container as the contents are withdrawn.

Abstract: 1349491 Determination of primary amino group containing compounds F HOFFMANNLA ROCHE & CO AG 20 Oct 1971 [21 Oct 1970] 48721/71 Heading B1X A reagent for the determination of primary amine group-containing compounds comprises a solution in an inert organic solvent of ninhydrin and an aryl alkyl aldehyde of formula Ar(CH 2 )n CHO, where n is 1 to 8. The reagent is mixed with the sample, the mixture is heated to produce a fluorescent substance and the amount of fluorescent substance is measured. The test may be carried out at pH 4 to 9, preferably 6 to 8. The sample may be the effluent from a chromatography column, when the effluent stream is mixed with a stream of reagent and buffer solution and passed through a mixing coil and a heating bath into a continuous flow cell of a fluorophotometer. The reagent may also be used for developing paper or thin layer chromatograms.

Abstract: 1,065,958. Moulding plastic substances. PROCTER & GAMBLE CO. Dec. 1, 1964 [Oct. 14, 1964], No. 48765/64. Heading B5A. For stamping a blank of plastic material, e.g. soap, into a pin-die shape, i.e. by a die pair meeting in face-to-face contact, the die pair 12, 13 each have a cavity edged by a land, that on the lower die 13 being externally bounded by vertical walls 15a, and that on the upper die 12 being externally bounded on three sides by a depending skirt adapted to telescope over the walls 15a, and the land on the remaining side of the upper die is externally bounded by a sloping surface 15b, the portion of the skirt opposite to the surface 15b being somewhat shorter than that on the other two sides, and the skirt being formed with ports 18 adjacent the lands for the escape of air and stamp die liquor during the moulding operation. In operation the dies are associated with a rotary pin-die press, the dies being arranged so that the shorter skirt portion is nearest the centre of the press. The function of the shorter skirt portion is to permit a chunky extrusion P of scrap material which does not adhere to press parts and can be easily collected. A similar extrusion P is formed at the right-hand side in Fig. 6 but it lacks the final cutting action of the skirt. The absence of the skirt causes a ribbon-like secondary extrusion S, which can be collected, the extrusion being pinched off upon reaching the full impression position of the dies.

Bitumen may be added, at the expense of the advantages of polymerized rubber over plain bitumen in compatibility with the cable insulation, and of low dielectric loss. Plasticity measured by penetration index may be raised by the addition of polyisobutylene and/or butyl rubber, or lowered by the addition of insulating oil. The material, which is stable to 150‹ C., is cold injected into a split box assembled tightly round the cable ends at the joint.

A further inert steeply inclined circumferential surface 25 of the shell may be subsequently engaged by the member 1 to expand the outer end faster than the inner end. The members 2-4 are temporarily held together by wire circlips in grooves 26, 27 and by mating tabs 40. Rotation between the shell and the member 1 can be prevented by forming the surface portions 11 and 21 of hexagonal cross-section.

To counteract the effect of atmospheric pressure on weight measurements, a weighing apparatus comprises a platform 8 (Fig. 2) supported on four hermetically sealed strain gauge load cells one under each corner thereof, two load cells 10 (12) being loaded in tension and the other two 9 (11) loaded in compression.
