Title: Heat storage method using salt water basin
Inventor: GORANSSON PER
IPC: F28D20/00
Filed: 1985-05-22
Abstract: The method of storing large quantities of heat for e.g. a heat pump, using natural resources, uses a reservoir with deep zones (5) and shallow zones containing salt water. The salt content is higher in the deep zones, and long term heat is stored in them. The surface layers can be heated by e.g. solar radiation, or warm water discharged from an industrial source. To heat the deep zones, various heat exchangers or hot water circulating devices can be used with their main heat distributing surfaces at low level. In one form warmer water (12) enters a U-shaped heat exchanger (1) at a higher level. and after passing to a lower level is discharged again at a higher level.

Title: Improved processes and machines for the manufacture of hollow bodies, especially bottles, by extrusion blow-moulding of materials called plastics, with greatly improved performance
IPC: B29C49/32
Filed: 1986-04-30
Abstract: The invention consists in carrying out an operating cycle for a machine for extrusion blow-moulding thermoplastic materials, in which the largest number of phases are superposed on the longest phase of the operating cycle, that is the cooling of the moulded part. It consists in using elements of known and novel machines such that, on intervening in the operating cycle, they permit this superposition of the sequences, in order to universalise the manufacture of the hollow body, on one and the same machine element. For this purpose, the contact of the two half-shells is performed at the actual moment of the reversal in the direction of movement of the mould or during the descent.

Title: Method for injection moulding, in the region of the air gap inside at least one of the pins, articles of haberdashery, and mould for the implementation thereof
Inventor: DARLET JEAN LOUIS
IPC: B29C45/33
Filed: 1986-07-04
Abstract: The subject of the invention is a method for injection moulding, as a web, in the region of the air gap inside at least one of the pins, articles such as articles of haberdashery, and its mould for the implementation thereof. It consists in injecting the material, from at least one of the holes of the article 8, into the pins forming these holes; the pins and the half-pins have lengths such that a void (or air gap) is provided between them when completely closing the various elements making up the mould, thus permitting the circular filling, "as a web", of the mould cavity via the runners (feed channels); after cooling the injected material and opening the various parts of the mould, the moulded article appears connected to its runners (feed channels), only a cap or web now remaining in the region of the hole of the article which is easily broken without leaving any trace, since the web is very thin. The invention applies especially to buttons and other similar articles.
