  • Patent number: 5622251
    Abstract: The invention relates to a transfer device for performing a regular, linear transfer movement including a body (1), provided with a threaded bar (2), a stepping motor (3) for driving the threaded bar (2), two guide bars (4, 5), a slide (6), and a follower (7) connected to it. The slide (6) is moved along the guide bars (4, 5) by the follower (7), which transforms the rotational movement of the threaded bar (2) into a linear transfer movement. The object to be transferred with the transfer bar (2) is attachable to the slide (6). The invention is characterized by the fact that the slide (6) includes an opening (8), through which the threaded bar (2) is fitted to pass with some play, and in connection with the opening (8) there is a follower (7), having a tongue (9), which is fitted to follow the threaded groove (10) of the threaded bar (2), so that the rotational movement (A, B) of the threaded bar is transformed into a linear movement of the slide (6) via the follower (7).

  • Patent number: 5576552
    Abstract: The invention relates to an image plate (1) for intraoral dental radiography which can be closed within a cover through which X-rays can pass, where the plate is retained during the X-raying and from where the plate can be removed after the X-raying in order to read the picture. According to the invention the edges of the image plate (1) are equipped with a protective frame (2) projecting from the plane of the plate surface at least on the image side of the plate. The frame may be formed as a continuous cover frame (2) surrounding the edges of the frame, consisting of two opposite frame-like portions (7) pressed together and optionally identical. The purpose of the frame (2) is to protect the image plate (1) against scratches or similar damages as the plate is being handled and read.

  • Patent number: 5518737
    Abstract: This invention describes a device for peroral administration of a therapeutic agent which is capable of existing in an unionized therapeutically active form. The device comprises a reservoir comprising the therapeutic agent in ionized form, which reservoir has a wall permeable to un-ionized material and impermeable to ionized material; and a solid material which upon uptake of water is converted to a buffer; the solid material having, on uptake of water, a pH which determines the rate of permeation of the therapeutic agent in un-ionized form through the reservoir wall. The device enables the release of the therapeutic agent to be controlled by the pH of the buffer and, if desired, the composition of the reservoir walls. The composition of the surrounding aqueous medium does not affect the rate of release.

  • Patent number: 5466561
    Abstract: The invention relates to an image plate (1) for intra-oral dental X-ray photography, the plate being placed in a shield (3) enveloping it for the duration of photography. According to the invention the shield has been made pervious to X-rays but impervious to visible light, and it comprises a closed shielding bag of plastic membrane. The shield may be made up of an inner shielding bag (3) impervious to light and a surrounding closed outer shielding bag which may be of transparent plastic membrane. After photography, the possible outer bag is first removed, the patient's saliva being removed along with it. Thereafter the image plate (1) and the surrounding shielding bag (3), one end (6) of which has been opened or, if an outer bag is used, is possibly already open, are introduced into the read-out apparatus, in which a pulling device grips the end of the plate in the bag, whereafter the bag can be pulled out while the plate remains in the read-out apparatus for the reading out of the image.
