Title: Apparatus for heat exchange between different liquid media
Inventor: KARLSSON BERNT
IPC: F28D9/00
Filed: 1990-12-17
Abstract: Apparatus for transfer of heat between different liquid media, such as for example sludge, sewage water, industrial process water or the like allows the transfer of heat between two polluted media. from a polluted medium to a clean medium or vice versa. A number of generally planar, parallel panels (A) are disposed one above the other. Suitably disposed partitions form intermediate, sinuous ducts. The ducts can be arranged in parallel or in series. They can be of a variable dimension, depending on instant placement and number of partitions determining the cross-sectional area of the duct. Hot and cold medium ducts (C, D, respectively) are arranged such that the flow of the two media takes place in a cross- and a counter-flow fashion along the ducts. The transfer of the respective medium (C; D) from one plane of the respective duct to another is carried out by means of end boxes (E). The partitions of the ducts, straight or curved, are detachably clamped by a suitable framework (G). <IMAGE>

Title: Reciprocal impendance conversion
Inventor: CHAMBERS CHARLES WILLIAM
IPC: H03H11/40
Filed: 1992-01-09
Abstract: A reciprocal impedance conversion network is disclosed. Such conversion network preferably is used in a reciprocal negative impedance repeater for the nonloaded cable facilities of a telephone system. Two independent voltage sources 34, 32 for generating reciprocal negative impedance are connected between a first port A and a second port B. The first port is operably connected to the first voltage source 34 such that a series negative impedance appears at that port. This port is specifically connected to the switching equipment of the telephone system. The second port is operably connected to the second voltage source 32 such that a shunt negative impedance appears at that port. The second port is specifically connected to the nonloaded cable facilities of the telephone system. The network further provides a frequency dependent gain circuit which is useful for equalizing the losses along the nonloaded cable facilities. In addition, the network provides an unconditional stability test for the reciprocal negative impedance repeater which may be performed substantially without test equipment. Also voltage feedback to the subscriber port proportional to subscriber current reduces the impedance as seen by subscriber line equipment and insures the proper operation of some impedance sensitive devices. Figures 7 and 8 show modifications of this basic idea. <IMAGE>

Title: Control of idling in an internal combustion engine
Inventor: IKUTA KENJI
IPC: F02D45/00
Filed: 1993-04-06
Abstract: A fuel injection system for an internal combustion engine introduces, via an air passage 27 bypassing a throttle valve 14, a portion of intake air flowing in an induction system of the engine to an area where fuel is injected from a fuel injection valve, so as to facilitate atomization of the injected fuel. The air passage includes therein a flow control unit 28 for opening and closing the air passage. During an ending idling, a total opening time of the air passage effected by the flow control unit is variably controlled for adjusting a supply amount of the intake air through the air passage so as to realize a target idling engine speed. As a result, the intake air fed through the air passage works not only to facilitate the atomization of the injected fuel, but also to control the idling engine speed to the target value. <IMAGE>
Patent GB-2266213-A (GB)
Title: Digital signal coding
Inventor: SEDGWICK NIGEL CHARLES
IPC: G10L19/038
Filed: 1993-04-08
Abstract: The present invention seeks to use a novel combination of techniques - primarily vector quantisation and variable duration segments with sophisticated segment models - to provide acceptable speech quality even at data rates as low as 600 bpss. It proposes that the signal be described in terms of a sequence of concatenated variable duration segments, where each segment is described by part of the digital data sequence, giving advantages based on better descriptions of variable duration segments that are longer on average, and on considering very large numbers of possible sequences of segments of various different lengths and choosing the best sequence from all those considered.
