Abstract: For the production of a one-piece corrugated jacket pipe of thermoplastic, the corrugated jacket pipe is formed to have corrugated partial sections which are deformed such that the direction in which they lie one above the other radially to the axis of the corrugated pipe is reverse to the direction in the locked condition after insertion of electric lines.

Abstract: An improved lightweight, multi-layer, reflective swimming pool cover containing two thermoplastic layers. The top layer has a dark-colored polyethylene film and the lower layer has a polyethylene film with a aluminum concentrate, or other suitable reflecting material, deposited thereon along the entire layer, thereby becoming a reflective surface. The layers are suitably bonded together to form a water and air tight seal so as to provide the cover with a reflective surface on which are integral reflective solar heating and insulative pockets configured in a predetermined spatial relationship to each other. The cover acts to continually reflect radiating heat back into the pool and provides an effective and enhanced insulation barrier against radiant heat loss from the pool.

An access aperture is located in the inner clamp member to permit access to the juncture between the two butting segments.

Abstract: The time to grind a workpiece can be reduced by selecting a grinding wheel whose width is not substantially greater than wheel strength considerations require, and which may therefore be less than the axial length of the region to be ground providing a work rest or work steady to increase the workpiece stiffness if required, and performing a succession of plunge grinding steps so as to grind the whole of the said axial region. Typically the grinding wheel is an electroplated CBN wheel, and the width of the grinding wheel selected is the narrowest permissible given the desired feed rate and motive power available.

Each of the filter elements is a three arm interferometer and each is fabricated utilizing integrated waveguide technology.

Abstract: A forming tool for extrusion has a die (5), which has a forming cavity (6) having at least one critical reference value. The die (5) is surrounded by a biasing ring (8), which bears against it with radial pre-stress. The die (5) and the biasing ring (8) have tampered contact surfaces (11) and are displaceable relative to one another. The biasing ring (8) is surrounded by a reinforcement (9), which bears against it with radial pre-stress. The biasing ring (8) and the reinforcement (9) are mounted in a fixed position on a carrier (housing 1). The die (5) is displaceable relative to the carrier and capable of being locked, by locking means (15, 19) on the carrier, in positions that can be selected. By that means it is possible subsequently to carry out a fine adjustment of the critical reference value over a wide correction range.

Abstract: A safety lock device including a clover mechanism mounted on a rotating shaft to be used with an unbalanced free-fall dog that precludes rotation of the rotating shaft upon rapid acceleration or excessive speed of the rotation of the shaft. The free-fall dog is pivotally mounted on a fulcrum upon which the free-fall dog may teeter in an unbalanced seesaw motion. At opposite ends of the fulcrum are a locking finger and an arm. The free-fall dog is unbalanced such that the arm contacts the clover mechanism as it rotates while the locking finger does not contact the clover mechanism at slow rotating speed. At a slow rotative speed, the arm is only slightly deflected. With great acceleration, the arm is deflected farther from the clover mechanism thereby causing the locking finger on the opposite side of the fulcrum to be pivoted into the clover mechanism.

Abstract: An ultrasonic location system for indoor environments, enabling the determination with high accuracy of the positions and orientations of objects to be tracked, wherein transmitting units (20, 22, 24) on the objects to be tracked transmit encoded ultrasonic pulses which are detected by receiver units (12 to 18) located by known positions around a room, and the receiver units are adapted to detect times-of-flight of the ultrasonic pulses in conjunction with decoding of the pulses to identify which time-of-flight applies to each transmitting unit.

Abstract: A route finder means and method for finding routes to satisfy a plurality of connection requests in a communications network comprising a plurality of nodes connected by a plurality of links. A cost is assigned to each network link. Arrays of eight shortest paths of links between each pair of nodes in the network are created. Bit strings comprising for example a 3 bit binary number for each point-to-point connection request are generated. Each 3 bit number is an index to one element of the shortest path array for each connection request's source and destination nodes. The bit strings are assembled into population members which are manipulated by genetic algorithms. The fitness of the population members is evaluated by calculating the cost of traversing the routes represented by the bit strings. The route finder means and method has an ability to split traffic over multiple routes, and to handle different traffic types, eg different bit rate traffic types.

Abstract: Current telecommunications device transmission stages require a significant number of analogue (DAC) components. The present invention provides a digital to analogue converter implementation for coupling to the digital signal processing (DSP) stage of the device and comprises a DAC and means to nullify the output of the DAC over part of the DSP data output period to produce a series of pulses corresponding to this data. The pulses are bandpass filtered to produce an analogue output signal at an intermediate frequency.

Abstract: A route finder for point to multi-point connection requests in a communications network comprising a plurality of nodes connected by a plurality of links. A cost is assigned to each network link. For each connection request a set of all network nodes not included in its source node or its plurality of destination nodes are selected. An array of bits is created with an array element corresponding to a selected node element having a value of 1 if the node is steiner vertex for a steiner tree of nodes not selected, otherwise the array element has a value of 0. Each array is treated as a bit string and considered as population members which are manipulated by genetic algorithms. The fitness of the population members is evaluated by calculating the cost of traversing the routes represented by the bit strings. The method is capable of routing a plurality of multi-point connection requests, and selecting an overall optimum solution.

Abstract: A method of printing uses a multi-nozzle ink jet print head having a pressure modulator for causing streams of ink emitted from the nozzles to be broken up into individual droplets. The nozzles are divided into a plurality of groups of nozzles, and groups of charge electrodes correspond, each group of charge electrodes having a respective charge controller. In the method a modulation waveform is generated to operate the pressure modulator to cause droplets to be generated in each stream. The charge controllers are operated to supply a charge signal waveform to charge electrodes and charge droplets in the streams. The phase relationship of the charge signal waveform is adjusted relative to the modulation waveform.

Abstract: Instead of a single beam, two coherent beams of light are used to illuminate a phase grating in spatially separated zones for writing a Bragg reflection grating in an underlying optical (fiber) waveguide. Close proximity between phase mask and waveguide is not required. This facilitates the use of masking so that only two different diffracted orders contribute to the fringe pattern that generates the Bragg grating, thereby improving fringe contrast and reducing the deleterious spectral effects upon the reflectivity of the Bragg reflector occasioned by the presence of stitch errors in the phase grating.
