  • Patent number: 5970735
    Abstract: The invention relates to a process for producing ice figures as well as a device for this purpose. A device in accordance with invention (901) is provided with at least two cooling bodies (905, 906) facing one another, and these are washed by water inside a container (902). The cooling bodies are cooled to below the freezing point of water by means of a refrigeration compressor (904) using coolant so that ice layers (918, 919) form on each cooling body (905, 906), and grow onto one another and then contact one another, so that the two ice layers freeze together, so that a single-piece ice figure is produced, where the completion of the single-piece ice figure is detected for example with a sensor (922). Once the single-piece ice figure is completed it is detached from the cooling bodies (905, 906) and removed.

  • Patent number: 5925282
    Abstract: When manufacturing a foil-wrapped breast prosthesis with a filling consisting of a curable compound, the curing is performed after placing a filled prosthesis bag formed by two joined foil sheets in a mold cavity without closing the mold cavity and maintaining vacuum at least in the beginning of the curing, whereby especially an increased degree of freedom is obtained with respect to shaping the rear side of the prosthesis, so that this, among other things, can be provided with thin edge parts for obtaining good fitting to the body. To ease the mounting of the bag and the accurate positioning of this in the mold cavity, the latter is formed in a first mold part of a shaping tool, which furthermore comprises a tightening frame having a packing, which provides an unambiguously oriented tightening of the bag when this is placed in the mold cavity.

  • Patent number: 5440082
    Abstract: In a method of manufacturing an in-the-ear hearing aid (25), a mould (23) is made of an ear canal for use as a moulding die for making a housing of the hearing aid. After the mould is made an auxiliary tool made up of a flexible tube (11) with a flange at one end is inserted into the ear canal into the proximity of the tympanic membrane of the ear. Subsequently, a curable material (19) is introduced into the ear canal. The material presses the flange against the tympanic membrane, which precludes the ingress of material between the flange and the tympanic membrane. After the material has cured the mould with the tube and the flange is removed from the ear canal. During removal of the mould the space between the tympanic membrane and the mould is in communication with the outer air via the tube, so that no partial vacuum is produced which otherwise might damage the tympanic membrane. The mould obtained is used as a moulding die for making a custom made in-the-ear hearing aid.
