Abstract: A device for measuring or visualizing temperature distribution along a line or an area, said device comprising areas of relatively good heat conducting or heat storing properties alternating with heat insulating or poorly heat storing areas, so that when the device is brought in contact with an object to be measured more heat energy is transferred to the heat absorbing or heat storing areas than to the heat insulating areas so that heat equalizing does not take place between the heat conducting or heat storing areas for a time, whereupon the temperature remains stable for a time.

Abstract: A closure device is designed for attachment on a neck portion (1) of a separate container (2), preferably of glass material, which holds a first substance. The closure device defines a passage (10) extending between opposite first and second openings (11, 13) of the closure device. A sealing means (30) is arranged to close off the first opening (11) and confine a second substance in the passage (10). A penetration means (33) is incorporated in the device and operable to penetrate the sealing means (30) such that fluid communication is established between the passage (10) and the container (2). In a method of mixing the first and second substances, a medical practitioner exposes the second opening (13) by removing a non-resealable cap (8), by introducing and engaging the end of a syringe directly in the second opening (13), and by operating the penetration means (33) to penetrate the sealing means (30).

Abstract: A valve for dispensing a preferably viscous fluid is adapted in connection with the dispensing operation to open under the action of a positive pressure in the fluid, produced e.g. by means of a pump (1), and to close by itself when the positive pressure, and thus the dispensing operation, has ceased. The valve (2) has a channel (9) with an inlet and an outlet end (9a; 9b) and an axial direction of fluid flow (10). The channel (9) is defined by a body portion (11) of rigid material and a cover portion (12) of flexible material. The body portion (11) is formed with a groove (13) of substantially arcuate cross-section. The edges of the cover portion (12) extending in the direction of flow (10) are sealingly connected to the body portion (11). Towards the outlet end (9b), the cover portion conforms to the shape of the groove (13). The cover portion (12) is prestressed to sealingly engage the wall of the groove (13) with a certain engagement pressure.
