Abstract: A soldering tip is provided with a sensor to sense soldering tip temperature during a soldering cycle. The sensor is embedded in the soldering tip and positioned immediately adjacent to the tip's working surface. The sensor location provides rapid response to changing conditions at the tips working surface. A microprocessor, responsive to the sensor, is provided to process the tip temperature data to control the power delivered to the heater which provides heat to the soldering tip. A visual and/or audio display also can be coupled to the processor. The microprocessor can be coupled to a further processor having long-term memory so that the collected data may be subsequently retrieved and displayed. <IMAGE>

Abstract: A permanent magnet structure having at least one loop of circulating flux comprises a first and second plurality of uniformly magnetized prismatic magnetic material sections forming a polygonal shaped cavity and having a point F positioned along a zero equipotential base line joining two vertices within the cavity, that point being the reference for a figure of merit M corresponding to a maximum field strength and a minimum ratio of the value of the area of magnetized material to the area of the cavity. The first plurality of sections totally define the cavity and have their respective remanences aligned to result in a flux passing orthogonally through the base line. The second plurality of section is oriented with respect to their respective remanences and the first sections so as to confine the flux within the cavity. A third plurality of nonmagnetized magnetic sections encloses the base line and borders the first sections for providing an inductive path to channel the flux and close the loop.

Abstract: PCT No. PCT/SE90/00710 Sec. 371 Date Apr. 22, 1992 Sec. 102(e) Date Apr. 22, 1992 PCT Filed Nov. 2, 1990 PCT Pub. No. WO91/07807 PCT Pub. Date May 30, 1991.A DC/DC power transformer is provided which is an arrangement for direct transformation of high electric power from one DC voltage level to another DC voltage level without an intermediate AC voltage network. The DC voltage is today basically used for transmission of high electric power at long distances. The DC voltage levels for these transmissions are normally high. The DC/DC power transformer allows several DC voltage levels to be used in one and the same DC voltage network. The principle for this arrangement is that the valve windings (43, 45) from one or several converter transformers (47) are connected to two valve bridges, which generate opposing cyclically variating magnetic flows in the transformer cores (44). One of the valve bridges is operated as an inverter (42) and the other as a rectifier (46) and in this manner the power is transformed from one DC voltage level (Ud1) to another (Ud2). At high voltage levels the leakage inductances in the transformers will be high as a consequence of the insulation levels and therefore special arrangements must be made in order to commutate the magnetic energy from one phase of the transformer to another without creating great losses.

Abstract: A radio alarm system is described which offers adequate protection against interference due to blocking of the radio paths and against external manipulation. For this purpose, it is proposed that each signalling unit of the alarm system transmits at least two radio signals for an alarm signal, using a different carrier frequency and being coded in identical or different fashion. The central unit accordingly receives with its receivers the at least two radio signals from each signalling unit and checks the affiliation of the signalling units transmitting the radio signals by checking the validity of the coding. It is proposed in addition that an evaluation unit be provided in the receiver unit of the central unit which identifies the field strength of each received radio signal, analyses the associated data telegrams for affiliation to the system of the signalling units transmitting them, if an invalid data telegram is detected, compares the value of the received field strength of the radio signal concerned with a predefinable minimum value and, if this minimum value is exceeded by a predefinable amount, where this amount must be exceeded for a specific time period, triggers a warning indicator. <IMAGE>

Abstract: An apparatus and method for providing a selectable novel reconnection algorithm for a repeater partition state machine to use in reconnecting a partitioned port. The reconnection algorithm permits selection of one of a first or a second partitioning/reconnection algorithm from a set of partitioning/reconnection algorithms. The first partitioning/reconnection algorithm corresponds to the IEEE 802.3 Standard partitioning/reconnection algorithm. The second partitioning/reconnection algorithm reconnects a partitioned port only upon minimum duration collision-free transmit activity from a partitioned port. The apparatus includes a partition state machine responsive to a counter controlled by a signal indicating the particular partitioning/reconnection algorithm selected and a device for selecting the algorithm. The signal determines whether the counter responds to receive and transmit activity or only to transmit activity. When the counter times that the minimum duration of the appropriate activity has elapsed and the partition state machine has seen activity without a collision, the port is reconnected as appropriate. <IMAGE>

Abstract: The hand set is intended for use in telephones and has a microphone and a receiver. The microphone and the receiver are arranged in capsule receptacles which exhibit a distance from one another and are coupled to one another by a connecting element. The receptacle for the receiver forms with its ear piece a reference area which can be arranged at an angle in such a manner that, starting from the reference area, an increasing distance with respect to a longitudinal axis results in the direction of the microphone. The microphone is constructed as a directional microphone, the rear slots of which are arranged in such a manner that, without mechanical pivoting a directional pattern is produced which points towards the human mouth. In the area of the receptacle for the microphone, at least one sound passage opening is provided in the area of a boundary wall. In the area of a speech receptacle delimiting the microphone, an edge extends which is raised above the speech receptacle and encloses areas of the microphone.

Abstract: The invention relates to a refuse container (1) for degradable waste, the interior of which comprises two vertically arranged volumes (5, 16), whereby it is intended that the liquid received with the degradable waste should collect in the lower volume (16), from where it can also be removed. On the one hand, this volume should be large enough to be definitely able to accommodate the liquid received, on the other hand emptying of the liquid section and of the refuse container itself should be easy and trouble-free, without backmixing of the waste with the liquid occurring. To this end, the lower volume (16) is separated from the rest of the container casing by means of a forked grid (14), which is normally horizontal, but which is pivoted about a horizontal axis in the container casing during emptying. Reliable separation of solid and liquid waste and complete emptying of waste from the refuse container are achieved in this way. <IMAGE>
