  • Patent number: 6359268
    Abstract: The invention relates to a process, a device and a receptacle for heating pre-prepared meals, it being possible for these meals to be accommodated in open or closed receptacles and heated by means of induction heating coils. In the catering industry it is customary for prepared meals to be heated by known circulating air ovens, a high energy consumption and relatively long heating times having negative effects, in particular in mobile use. In the case of inductive heating of such prepared meals, it is necessary to use corresponding special kitchenware which is suitable for this purpose. The object of the invention is to achieve the heating in a highly effective manner and with good quality, with low expenditure in terms of time and energy.

  • Patent number: 6294765
    Abstract: A control system includes a variety of structures including a steam table having a reservoir with heating elements, a water level temperature probe, a safety lower temperature probe, upper overflow probes for use in filling, lower safety probes, and normal water level probes; a thermal cabinet, ice machine and other thermal devices. The controller utilizes at least one of relay shaking, probe movement checking, probe feedback checking, disappearing equipment, water working system, air flow factoring, best verifiable logic, pulse cooling, AC energy sensor analysis, cooling potential sensor analysis and pulse heating to keep the heating elements at a more even temperature during the heating process and reduce extreme thermal cycling. In addition, the system can locate intermittent problems and display the problems to workers or management, or to a central controller to initiate action in advance to repair the problem before it causes a breakdown in the equipment.

  • Patent number: 6256446
    Abstract: A variable attenuator includes a rotatable actuator and cam arrangement arranged to vary a length of an air gap between ends of fibers in a transmission line. The cam arrangement includes a cylindrically shaped cam member having an end surface cut to fit a curve representing normalized attenuation-to-gap-length data, the cam follower(s) being fitted in a sliding member that holds the end of the optical fiber and moves it relative to a fixed end of another fiber connector member. The cam surface includes multiple identical cam surface sections extending less than 180° around the cam to define movement of the cam follower(s) and the sliding member between a maximum position and a minimum position.

  • Patent number: 6005851
    Abstract: To transmit a stream of data packets over a physical channel, virtual channels for each data type (e.g. video, graphics, text) are created and mapped onto the physical channel based on a priority assigned to each virtual channel. Each virtual channel is also assigned a quality of services (QoS). A channel controller is allocated to each virtual channel. These channel controllers are connected to a dispatcher which receives the stream of data packets and distributes the data packets to the channel controllers based on the virtual channel to which the channel controllers are allocated. Should a channel controller encounter degradation in a transmission which reduces QoS below the specified values, a QoS parameter is adjusted. If this action does not achieve the specified QoS, the channel warns the dispatcher. The dispatcher, upon receipt of the warning, may, depending on the data type, reduce that channel controller's specified QoS or another channel's QoS.

  • Patent number: 5971776
    Abstract: An adjustable spark plug boot in accordance with the present invention includes an assembly, a first groove, a first terminal locator chamber, and a second terminal locator chamber. The assembly has first and second ends with a bore extending from the first end to the second end. The assembly includes an elongated section which extends from the first end along a first axis. The first groove extends at least partially around an outer surface of the elongated section and is in a plane which is substantially perpendicular to the first axis. The first terminal locator chamber is located in the bore in the elongated section. The second terminal locator chamber is also located in the bore in the elongated section and adjacent to the first chamber. The first chamber may have a first side which is opposite from the first end and is spaced a first distance from the first end and the second chamber may have a second side which is opposite from the first end and is spaced the first distance from the first groove.

  • Patent number: 5943460
    Abstract: An adhesiveless fiber optic connector includes a collet mechanism having cable gripping fingers for initially gripping a fiber buffer upon movement of the collet into a body of the connector, and which is subsequently secured within the connector by crimping, includes keying tabs which cooperate with slots in the main body of the connector for retaining the collet within the connector prior to termination, and for preventing rotation of the collet during termination, the keying tabs being pushed out of the slots during termination to adhere to the main body of the connector following crimping. An apparatus for facilitating termination of a fiber optic cable to such an adhesiveless connector includes a transport mechanism to which the fiber buffer is clipped, and a guiding mechanism in the form of separable jaws for the exposed fiber, as well as a crimp mechanism and fiber cutting and polishing apparatus.

  • Patent number: 5710851
    Abstract: A strain relief system for a fiber optic connector includes a boot made up of two halves, the halves being fitted together by press-fit pins supported by a flange which also serves increase the rigidity of the boot. The boot is held in place on the cable by using internal ribs at an distal from the connector. The force required to make the ribs hold the boot in place is provided by stretching a standard elastomeric boot over the outer diameter of the section containing the ribs. The system further incorporates a support clip at the connector end to assist the two halves in staying together and further resist lateral bending moments. The outer profile of the support clip can be adapted to fit a variety of different connector configurations, and thus the support clip also serves as an adapter for the strain relief system.

  • Patent number: 4195337
    Abstract: A control method is described in which, a plant, a reference model and a corrector are serially connected in the loop. The plant output is fed back and compared against a reference signal to develop an error signal. The reference mode operates upon the error signal with a predetermined transfer function to develop signals proportional to the error signal and various successive order derivatives of the error signal. The model output signals are applied to a corrector circuit which multiplies the respective model output signals by appropriate coefficients, and sums the resultant product signals to produce control signals for the plant. Provisions are also disclosed for varying the coefficients to provide self-adaptive control. Provisions for accommodating process delays are also provided.
