Abstract: A structural arrangement for an evaporator (heat exchanger) producing a substantially uniform temperature gradient across its width. The structure is arranged so as to even out the flow of refrigerant within the evaporator. A first tank portion (200) has a refrigerant inlet (2a) and a second tank portion (202) has a refrigerant outlet (28). One end of each of plural tubes (7) are connected thereto. A plurality of tubes (7) allow refrigerant to flow from the first tank portion (200) to the second (202). The tubes (7) are arranged so as to provide substantially equal flow distances for refrigerant across the entire evaporator, taking into account the directions of flow in the first and second tank portions (200, 202). In a second embodiment, the inlet port (2a) and the outlet port (2B) are disposed at the first tank portion (200) and the second tank portion (202) respectively in such a manner that directions of the refrigerant flow within the first tank portion (200) and the second tank portion (202) are opposite to each other. In a third embodiment, one of a first tube of the plurality is connected to the first tank portion (200) closer to one end of the first tank portion (200) that where one end of a second tube of the plurality is connected. The other end of the first tube is connected to the second tank portion (202) closer to the other end of the second tank portion (202) than the other end of the second tube. The inlet port (2a) is disposed close to one end of the first tank portion (200) and the outlet port (2b) is disposed close to one end of the second tank portion (202).

Abstract: A tape cassette (79) has a separate, plastic molded, elongated, tape guide subassembly (80), which incorporates two bearing extensions (116,118) integrally molded at the left and right ends thereof. Each bearing extension has a pair of opposing, parallel, planar members (120,122) extending from support members (123) each of which is parallel to the planar top and bottom of the tape guide subassembly. Each planar member includes a roller receiving means (124) integrally formed therein and the rotational axles for the tape rollers (110) are either integrally molded as part of the bearing extension or the tape roller itself. The planar members in each pair have the ability to flex only in the direction perpendicular to their planes, allowing the rollers to be easily snapped into place during assembly. Once the rollers are inserted into the tape guide subassembly, the latter is assembled into the front of the tape cassette, wherein the rollers form part of the central tape support area of the tape cassette. Related methods are also described for manufacturing the tape guide subassembly and the whole cassette.

Abstract: For the simple avoidance of undefined switching states of the three-phase bridge (5) during the switching-on process of a frequency converter (6), the unregulated supply voltage to the control electronics, which has a specific switching on slope as a result of the internal resistances in the transformer and rectifier, is supplied via a time delay element (21) to a comparator (17) which produces a release signal to the power electronics if a comparison level is exceeded. The delay time of the time delay element (21) is longer than the time which is taken to reach the control level of an associated voltage regulator (26) when the voltage supply to the control electronics is switched on, as a result of which the release signal cannot occur until the control electronics are in the steady-state condition.

Abstract: Apparatus for analyzing particles contained in a fluent medium (12). The apparatus includes a body (20) having a window (30), an optical source preferably comprising a laser diode (100) having a small light emitting area (140), and an optical system (102) for focusing the light from the laser diode at a focal spot (84) such that the size of the focal spot is approximately equal to the size of the light emitting area of the laser diode. A photodetector (106) is mounted in the body and detects light backscattered from the focal spot by particles in the fluent medium, and produces an electrical signal that comprises a series of pulses associated with the particles. The electrical signal is input to a detector that counts the pulses and indicates the number of particles in the fluent medium. The detector includes discrimination means for preventing the counting of a pulse that has a rise or fall time above a predetermined threshold, thereby discriminating against particles that are not at the focal spot. Means are provided for measuring the integrated amplitude of the electrical signal, and for varying the distance between the focal spot and the window to maximize such integrated amplitude. An intrinsically safe embodiment is also disclosed in which the probe positioned at the measuring site does not include any electrical components. This embodiment may be implemented using light of multiple wavelengths for characterizing individual particles.

Abstract: A system (15) comprises a service processor (20) and a plurality of operating units (21a-21p) dependent on the service processor. The service processor responds to service requests from the operating units and services the operating units one at a time. A scheduler (112) is responsible for assigning priority to the operating units and determining the order in which the service requests are handled. A register (87) contains a value indicative of the operating unit currently being serviced and is under control of the scheduler. According to one aspect of the present invention the register is also under control of the service processor itself. Another register (88), under control of the service processor, is coupled to the scheduler to generate service requests thereto independent of the operating units. A memory (114) addressable by the service processor stores data. The service processor is capable of generating addresses for the memory derived from the contents of the register indicative of the operating unit currently being serviced.
