Patent EP-0343937-A1 (EP)
Inventor: FINCH STANLEY GEORGE
IPC: F23M5/08
Filed: 1989-05-23
Abstract: A gas fired boiler for a domestic hot water and/or central heating system has a burner 25 (Fig. 1), a static heat exchanger 22 through which water is circulated, and a rotary heat exchanger 12 of which the body is a disc of ceramic material such as is currently used for catalytic conversion in automobile exhaust systems. The rotary heat exchanger recovers heat from the gases passing from the static heat exchanger 22 to the outlet flue 4, and uses this recovered heat for heating the fresh air entering through the air intake 3. A conduit 90 having a controllable valve 91 enables heated fresh air to be supplied for space heating purposes if required, whilst improving the thermal efficiency of the boiler by promoting condensation of water vapor from the combustion gases as they pass through the rotary heat exchanger.

Abstract: A method of, and apparatus for, identifying human tissue which is suspected of being physiologically changed as a result of commencement of neoplastic activity or pre-activity, is disclosed. The tissue is preferably irradicated with light at wavelengths of 660nm and 940nm (6, 3, 7, 4). The magnitudes of the reflected (5, 8), or non-absorbed, light at the two wavelengths is compared (20), preferably after being normalised by the magnitude of ambient light reflected from the tissue immediately prior to each measurement. The invention finds application in detecting cervical lesions but is also applicable to endoscope inspectable tissues such as the lungs and alimentary canal tissues.

Abstract: A current amplifier including two stages. A first stage is formed by a primary operational amplifier (IC1) connected in a virtual earth feedback configuration and having a feedback loop formed by a resistor (R1) and capacitor (C1) connected in parallel so that the primary operational amplifier has a frequency response up to a predetermined frequency and thereafter the frequency response rolls off at a predetermined rate. A second stage including another operational amplifier (IC2) connected in a virtual earth or non-inverting feedback configuration having a frequency characteristic chosen to provide in combination with the frequency characteristic of the primary amplifier a desired operating range for the amplifier. The predetermined frequency lies between the frequency extremes of the operating range and the frequency characteristic of the second stage has a constant gain up to said predetermined frequency and a gain matched with and complementary to the roll-off of the primary operational amplifier (IC1) above the predetermined frequency so that the overall frequency response of the current amplifier is flat over its operating range.

Abstract: A portable communications receiver is disclosed having a receiver for receiving and detecting periodically transmitted selective call paging signals and data signals. In response to the selective call paging signal, a decoder generates control signals which allow storage of the data signals in a memory, and the display of the latest stored signals. A graphic characterization is provided for depicting the moving object. The effect of movement of the object is generated as the data signals are periodically updated and displayed. By individually animating the graphic characterization between updates, the effect of movement is enhanced. The data signals are periodically updated and include an absolute position signal for depicting an absolute position of the moving object. The data signals further include a relative position signal for depicting a relative position of the moving object relative to another moving object.

Abstract: Un procédé permet de provoquer un état de détente chez une personne ou un animal. Un générateur (2) génère un signal avec une fréquence inférieure aux fréquences audibles et le transmet par deux canaux (4, 5) à un amplificateur correspondant (8, 7). La réponse fréquentielle dans le premier canal (5) est rectifiée de manière à ce que les signaux transmis par les deux canaux présentent la même fréquence mais des caractéristiques d'amplitude opposées. Le signal utile contenant par exemple les données à apprendre est transmis aux amplificateurs (7, 8) par deux canaux supplémentaires (9, 10) et y module les signaux du générateur (2). Les signaux modulés sont transmis séparément au système auditif de l'élève par une oreille.

Abstract: Un arbre désaccoupleur à limitation de couple (58) transmet un couple d'entraînement dans une première direction sans action de limitation du couple. Cependant, un couple appliqué à l'arbre dans un sens opposé au couple d'entraînement se traduit par une force de séparation axiale entre deux portions (64, 66) de l'arbre désaccoupleur (58). Lorsque le couple inverse atteint un certain niveau, une barre de contrainte cassante (82) se casse pour permettre le désaccouplement des portions d'arbre. Un composant (70, 80) de l'arbre empêche le réaccouplement indésirable des portions (64, 66) d'arbre tout en s'assurant que les portions d'arbre en rotation relative ne forment pas un fléau. Un démarreur (10) de turbine à air comprend un tel arbre désaccoupleur (58).

Abstract: This invention relates to improvements in making mats of continuous fiber strand using controlled reciprocating strand feeders. More particularly, the invention relates to improvements in making continuous fiber glass strand mats having more uniform density by electronically controlling both the rate of reciprocation and the rate at which strands are deposited onto the surface of a moving conveyor while also reducing the vibration associated with the feeders. Still more particularly, the invention relates to improvements in the production of two continuous fiber glass strand mats, one having uniform mechanical properties while the other possesses directionally dependent ones. 
     In the preferred embodiment, brushless stepper or indexing motors are used to reverse the direction of reciprocating strand feeders quickly and smoothly so as to minimize their vibration. Also provided are variable speed electric motors in conjunction with a programmable logic controller and frequency inverter to adjust the rate at which strand is deposited by the feeders onto the moving conveyor. 
     It is shown, by way of example, that these improvements result in increased uniformity of both mat density and thickness.
