Abstract: A sealing system for a cable fitting element of heat shrinkable material having a longitudinally extending opening with at least one longitudinally extending bead portion being disposed along a side of the opening and being receivable in a clamp portion forming a seal of the opening characterized by one of the clamp portions and bead portions being substantially rigid and unaffected by heat and the other of said bead and clamp portions having a permanent shape which is tightly engaged with the one portion to form a seal. To facilitate assembly, the other portion has a temporary shape and has been deformed to a temporary shape to enable easy assembly and will return to the permanent shape when the fitting element is heated to an elevated temperature for the shrinking process. In one embodiment, the clamp portion is a separate rigid member and the bead portion projects along the opening having one surface forming a sealing surface and the other surfaces engaged by the clamp. In another embodiment, the bead portions are adjacent sealing surfaces and the clamp member is telescopically received in the area and provides for a shrinkable portion of the fitting element. In a third embodiment, the seal is formed by a snap-fit between the clamp member which has a groove for receiving a projection of the bead portion and one of the two members or portions will be changed under the affect of heat to cause the engagement.

Abstract: A servo control apparatus for maintaining a scanning device, such as a beam (15) of radiation, aligned with an information recording track on a moving recording medium, such as a record disc (11). The apparatus is especially adapted for use in correcting for tracking deviations brought about by temperature-induced expansion and contraction of the disc, which causes the recording track being scanned to move radially outwardly or inwardly relative to the beam of radiation. In the preferred embodiment, the apparatus includes a movable mirror (39) for oscillating the beam in a radial direction, in accordance with a periodic dither signal (Figure 3). This causes a corresponding variation in the intensity of the beam (41) reflected by the disc, with the amplitude and phase angle of this intensity variation (Figure 4) relative to that of the dither signal, indicating the direction and magnitude of the deviation of the beam from the track centerline. Whenever the magnitude exceeds a prescribed level, a step forward or step reverse pulse signal is coupled to a stepper motor (45) to increment the beam in the appropriate radial direction, whereby the beam is maintained substantially aligned with the centerline of the recording track.

Abstract: In a device for removing warts using liquid nitrogen, a metallic cooling rod (12) is provided, in whose inside a temperature sensor (4) is arranged. The temperature sensor is connected to an electrical temperature measurement device by way of a cable connection. For removing the warts, the cable connection is detached and an insulating tube is pushed over the cooling rod, with which tube the cooling rod is gripped and treatment is carried out. A temperature check during treatment is not possible. The treating physician therefore requires a great deal of experience in order to meter the cold supply to the optimum effect. In order to simplify treatment, the cooling rod is held in a pistol-like grip (1) in which the temperature measuring device (5) is arranged and on which the temperature display (8, 9) is situated. The temperature can be indicated visually or by sound. The device is optimised by means of a time-measuring facility (10) arranged on the grip. <IMAGE>

Abstract: A sensor for detecting the amount of O 2  and combustible gas in a gaseous mixture uses two electrochemical cells (20,40) operating in sequence, to detect oxygen and gaseous combustible contents respectively; the first electrochemical cell (20) is a molten carbonate electrochemical cell operating at a temperature between 400 and 700°C and is used to remove O 2  in combination with CO 2  from the oxygen/ combustibles gas mixture to provide a low temperature measurement of the oxygen content of the gas mixture. The second electrochemical cell (40) is an oxygen ion conductive using catalyzing electrodes (44,46) and an external source of O2, e.g. air, to cause combustion of the combustible components of the mixture. 
     The cells (20, 40) each have electrodes (24,26;44,46) applied across cell-walls to apply a potential to cause oxygen transport across the cell walls. The current flowing through across the cell-walls in a measure of either the oxygen content or the oxygen required to oxidize the combustible gaseous contents.
