Abstract: A vehicle tyre, in particular for heavy lorries, has a body 1 with a tread 2. Inside the tread 2 runs a belt 3 and transversely thereto a radial armour 4. Embedded in the tread 2 are screw springs 5, whose axes run approximately radially. The screw springs 5 embedded in the tyre material absorb a portion of the forces acting on the tyre so that the tyre material itself is thus relieved. <IMAGE>

Abstract: A complete production line (10) of a wood I-beam manu­facturing apparatus and the method of manufacture is disclosed wherein generally identical chord members (12,14) are simultaneously formed by cutting of a wooden stock material (18) into the chord members (12,14) and simultaneously providing grooves (32,34) in one surface of each chord (12,14) into which web members (16) are received to form the I-beam. The individual web members (16) are conveyed along a chords and webs assembly line between the grooved chords (12,14) and the chords (12,14) are converged so that the grooves (32,34) interfit with the web edges (17) to form the I-beam. The web longitudinal edges (17) are preferably beveled in an off-line beveling operation. The beveled webs (16) are stacked (D) for feeding into the chords and webs assembly line. Prior thereto, first and second glue layers are applied to one transverse edge of each stacked web member. The web members  (16) are subsequently conveyed in the assembly line in end-to-end abutting relationship. The chords (12,14) are independently driven at a speed greater than the webs (16) so that the in-line chords abut each other in end-to-end relationship to minimize wast of material. Prior to abutting each other, a trailing end of one of the chords is sensed to actuate a flying cut-off saw positioned at the end of the production line by a distance equal to the desired length of the cut beam. After cutting, the cut beams are conveyed off the line for inspection and packaging.

Abstract: An optical fiber (300, 500, 602, 662a, 662b, 700) is subjected to a series of traveling flexural waves or microbends propagating along a length of the fiber. At least a portion of an optical signal propagating within the optical fiber in a first propagation mode is coupled to a second propagation mode. The optical signal in the second propagation mode has a frequency which is equal to either the sum of or the difference between the frequency of the optical signal in the first propagation mode and the frequency of the traveling flexural waves or microbends. The frequency of the optical signal in the second propagation mode is shifted upward or downward from the frequency of the optical signal in the first propagation mode as determined by the direction of propagation of the first optical signal with respect to the direction of propagation of the traveling flexural waves or microbends, and as also determined by whether the phase propagation velocity of the optical signal in the first propagation mode is greater than or less than the propagation velocity of the optical signal in the second propagation mode.

Abstract: A fluorescent tube lampholder comprises a flat base (30) which is arranged to receive the end of a fluorescent tube, and two sockets (32, 34) to receive the pins of the tube. The distance (d) between the live socket (32) and the periphery of the base (30) is greater than the distance (s) between the two sockets. Thus, the user cannot accidentally receive a shock by inserting one of the pins into the mains socket (32) while the other pin is free; this is prevented by the other pin fouling the base (30). The other socket (34) need not be similarly protected since it is connected to the starter switch side of the circuit and is therefore dead unless the tube is correctly plugged into both the sockets.

Abstract: A transistor (30) constructed in accordance with our invention includes a substrate (31) of a first conductivity type and first and second regions (32, 33) of a second conductivity type formed within the substrate. A gate (30g1) is formed over the portion of the substrate between the first and second regions. The transistor can operate in either a first mode, in which the first region serves as a source and the second region serves as a drain, or a second mode, in which the first region serves as a drain and the second region serves as a source. During the first mode, the substrate is coupled to the first region and during the second mode, the second region is coupled to the substrate, thereby permitting the transistor to operate in forward or reverse mode, while still biasing the substrate.

Abstract: In a semiconductor detector having a completely or partially depleted base area of a first conductivity to which a bias voltage has been applied and having at least one readout electrode at which the charge carriers generated by the incident radiation generate a signal, the following features are proposed:
 1. The readout electrode consists of a highly doped area of the first or second conductivity on which an insulation layer and then a conductive electrode layer are applied, at which the influenced signals can be tapped off and
 2. The voltage is conducted to the highly doped area of the readout electrode in a high-impedance manner via the base area of the detector from at least one electrode of the same conductivity as the readout electrode. 
<??>It is thus achieved that a capacitive isolation is possible in a simple manner even with a complex design.

Abstract: The magneto-optical recording medium is disclosed which has a laminous structure with a first magnetic film (11) suited to provide a large rotation angle of the plane of polarization by magneto-optical interaction, a third magnetic film(13) having a great corercive force, and a second magnetic film (12) interposed therebetween to magnetically couple the first and third magnetic films at room temperature, wherein such magnetic coupling is substantially interrupted at a temperature in a recording operation. 
Upon recording signal on the medium, a laser beam is irradiated to the medium and raise the temperature of the medium near Curie temperature Tc3 of the third magnetic film, thus direction of the magnetization is determined by the magnetic field applied to the irradiated portion. 
Upon cooling the irradiated portion, the second magnetic film serves to magnetically couple the first and third magnetic film, the magnetization of the third film is transferred to the first film. Thus the required magnetic field for recording is greatly reduced, and   high C/N can be obtained resulting in high density recording.

Abstract: A simplified fluid dispenser (20) for dispensing precise quantities of fluid without requiring special seals, particularly sliding seals, or springs. It comprises a housing (22) defining a fluid reservoir (24), having an inlet (26) for delivery of pressurized fluid to the reservoir (24), and including a valve seat (44) defining an outlet (42) for dispensing fluid from the reservoir (24). A deformable closure member overlies an open end of the housing (22) opposite the outlet (42) and normally biases a valve engageable with the valve seat (44) to the closed position. When the closure member is selectively deformed, the valve is able to move to the open position to dispense a quantity of the fluid from the reservoir. When re­leased, the closure member returns to its normal condition, returning the valve to the closed position instantaneously shutting off the dispensing of fluid. This operation causes the fluid being dispensed to rapidly reverse direction resulting in an immediate termination of flow and elimination of drippage.
