Abstract: In a district heating pipe with an interior tube (2) and an outer tube (3), and with a vacuum in the annular space (4) between the interior tube (2) and the outer tube (3), the annular space (4) is partitioned (5-7) at, for example, intervals of 500 to 600 m. The partition (5-7) is bridged by a line (9) which can be closed by a motor-operated valve (13) controlled by a pressure switch (11). If the pressure in the annular space (4) rises as a consequence of a leak, the bridging lines (9) are closed when the pressure increase has reached the threshold value of the pressure switch (11). The further increase in pressure is thus restricted to that section of the district heating pipe in which the leak has occurred. In a control room, to which the data from all partitions in the district heating pipe are transmitted, the section affected by the leak can immediately be identified. The damage is thus restricted and can rapidly be corrected. <IMAGE>

Abstract: An achromatic fiber optic coupler of the type wherein first (F1) and second (F2) single-mode optical fibers, each having a core and a cladding, are fused together along a portion of the lengths thereof to form a coupling region (N). A matrix glass (10) of lower index than the fiber claddings surrounds the coupling region (N). The fiber diameters are smaller in the coupling region than in the the remainder of the fibers. The refractive index n₂ of the cladding of the first fiber is different from the refractive index n'@2 of the cladding of the second fiber, the difference between the refractive indices n₂ and n'@2 being such that the coupler exhibits very little change in coupling ratio with wavelength over a band of wavelengths.

Abstract: A digital intermediate frequency (IF) receiver for frequency division multiplexed (FDM) signals including analog circuitry for receiving FDM signals and an analog-­to-digital (A/D) converter for converting the received signals to a sampled digital received signal. A digital complex mixer responsive to the digital output of the A/D converter translates the spectrum of the sampled digital received signal to center the desired FDM channel at zero frequency (DC). Digital low pass filtering isolates the desired channel centered at DC, and a digital complex mixer can be used to translate the isolated selected channel to a predetermined IF frequency. The in-phase portion of the digital IF centered selected channel or the DC centered complex envelope selected channel can then be provided to appropriate demodulation or decoder networks.

Abstract: The frequency of a clock for a receiving terminal is controlled based on a predetermined clock frequency of a terminal that produces a continuous stream of data at a predetermined frequency for transmission to the receiving terminal over a communications network of the kind in which data is transmitted between the terminals in discrete packets that are delayed on the network by possibly different amounts. Arrivals of packets that are sent to the receiving terminal are detected, time intervals between the arrivals of successive packets are determined, and the time intervals are processed to generate an estimate that is related to the predetermined frequency. The frequency of the receiving terminal clock is controlled in response to the estimate.

Abstract: An electromagnetic actuator arrangement comprising a switch (SW1) biased open by a biasing spring (SP) and operated by a yoke (Y1) which attracts an armature (AR1) when its winding (L1) is energised is provided with means (C1, SCR1) for instantaneously reversing the magnetising force acting on the armature when the winding (L1) is de-energised. As a result, the residual magnetism in the armature (AR1) is opposed by the reversed magnetic field from the winding (L1) and the tendency of the armature to stick to the yoke is avoided. Consequently the release time is reduced.

Abstract: A pressure transducer having a pressure sensing surface (13) spaced from an interior surface of the transducer housing by a relatively rigid back-up ring (17) which contacts each of the pressure sensing surface (13), the interior surface (7) of the housing and an interior side wall (5) of the housing. A relatively less rigid O-ring (19) is disposed between the pressure sensing surface (13) and the interior surface (7) of the housing and contacts the back-up ring (17), the back-up ring (17) and the O-ring (19) providing sealing of the pressure cavity. The O-ring communicates with the fluid entering the housing via an inlet in the housing. Because the output of the pressure sensing element is affected by the loading of the O-ring and back-up ring, and because this loading changes over time, mainly due to cold flow, compression set, etc.), several special procedures are provided during manufacture and before calibration of the transducers to minimize this problem to avoid calibration change (drift) over time, these being conditioning or burning in prior to calibration. This is accomplished by an extended high temperature soak through a series of pressure cycles or overpressure cycles or a combination thereof and permits the back-up ring and the O-ring to be relieved of stresses so that they will be stable over time.

Abstract: An apparatus is disclosed for forming objects from a moldable material such as wax. 
     The apparatus includes a die with a upper and lower mold pieces, defining a mold cavity for receiving the moldable material, and an injection chamber for containing the moldable material to be injected into the mold cavity. The moldable material is displaced from a cylinder and piston assembly through a conduit into the mold cavity. The piston is driven via a rotary to linear motion converter coupled to a motor driven rotating power shaft. The rate of advancement of the piston relative to the cylinder is monitored by a resolver which detects rotation of the power shaft to thereby determine the rate of displacement and amount of moldable material being conducted into the mold cavity. A closed loop servo feedback controller is operably connected to the resolver and to the motor powering the piston to provide continuous closed loop feedback control over the rate and amount of displacement of moldable material conducted into the mold cavity. 
     The apparatus includes upper and lower mold pieces having upper and lower mold cavity halves attached thereto. A lever arm extends from the upper mold piece and is pivotably attached to a linear actuator. The upper and lower mold pieces are pivotably connected to one another. 
Movement of the linear actuator results in opening and closing of the upper and lower mold pieces.
