Patent EP-0372366-A1 (EP)
Inventor: FUKUYAMA YOSHIKI
IPC: C10N30/02
Filed: 1989-11-29
Abstract: The electroviscous fluid is a suspension composed of a finely divided dielectric solid dispersed in an electrically nonconductive oil. The viscosity of the fluid increases swiftly and reversibly under an influence of electric field applied thereto and the fluid turns to a state of plastic or solid when the influence is sufficiently strong. 
     The electroviscous fluid of the present invention comprises
     (A) 1-60% by weight of a dispersed phase composed of crystalline zeolite having the following properties (1), (2), (3) and (4). 
(1) a general formula M (x/n)  [(AlO₂) x (SiO₂) y ]·wH₂O, 
wherein, M is a hydrogen ion, a metallic cation or a mixture of metallic cations having an average electron value n; x and y are integers; w is a mole number of crystallization water, 
(2) Si/Al atomic ratio (y/x) of 10-200, 
(3) a water content of 0.05-10% by weight and 
(4) an average particle size of 0.01-20 micrometer, 
and   (B) 99-40% by weight of a liquid phase of an electric insulating oil having a viscosity of 0.65-500 centistokes at room temperature.   
     The electroviscous fluid exhibits an excellent electroviscous effect with a low electric power consumption together with a quick response at the application and cancellation of an electric potential difference.

Abstract: The invention relates to a device for monitoring the serviceability of an incandescent lamp (1) connected to a power source (2) by means of leads (3,4), it being possible to check the continuity of the circuit at low power in the switched-off state, without any visible effect on the incandescent lamp (1), and/or by confirming an energy flow in the switched-on state. In order to be able to differentiate between circuit continuity resulting from a short-circuit or shunt circuit and the continuity of the circuit when the incandescent lamp is operated during such a test, and to exclude the possibility of a positive test result despite a defective incandescent lamp, the ratio of the resistance of the arrangement when the incandescent lamp (1) is in the switched-off state to the resistance of the arrangement when the incandescent lamp (1) is in the switched-on state is determined and is compared with the ratio of the cold-hot resistance which is applicable to the respective incandescent lamp (1) to be monitored, taking into account the lead conditions, to output a report for the monitoring result. <IMAGE>

Abstract: In a receiver for use in a remote-control system in which messages are radio-transmitted by means of infrared light, the receiving photodiode circuit is of the forward-biased type and is connected in the forward direction between ground and a voltage which is lower than the knee voltage of the photodiode circuit. As a result, a photocurrent I P0  is supplied by the photodiode circuit itself. The low-frequency component of this photocurrent can now be utilized as a charge current for a rechargeable battery. Its lifetime will thus be considerably longer.

Title: Procede et appareil pour le dosage d'un fluide
Inventor: EKLOEF ULF
IPC: G01F11/02
Filed: 1989-06-21
Abstract: Procédé et appareil destinés à distribuer, pendant une courte période de temps, un volume prédéterminé de fluide, à un débit sensiblement constant. La nouveauté de l'invention réside dans le fait que le fluide est introduit à débit constant, dans un appareil doseur et traverse cet appareil à un même débit, dans un premier parcours d'écoulement. Pendant une période de temps prédéterminée, l'écoulement du fluide à travers l'appareil est stoppé en empêchant sa sortie dudit appareil, le long du premier parcours d'écoulement, de sorte qu'un volume désiré de fluide est distribué dans l'appareil doseur, et que le fluide quitte cet appareil, à un débit constant, dans un second parcours d'écoulement. Pendant une courte période de temps, le volume dosé de fluide est amené à s'écouler de l'appareil doseur, dans le second parcours d'écoulement. A partir de l'appareil doseur, le fluide est amené à s'écouler, à débit constant, le long du premier parcours d'écoulement, tout en empêchant le fluide de pénétrer dans l'appareil doseur. Pour remplir la chambre doseuse de l'appareil, le fluide est introduit à débit constant et s'écoule à travers l'appareil doseur, dans ledit premier parcours d'écoulement, pour sortir de cet appareil à un débit sensiblement constant.

Each module includes a rotary bone holder (30) that supports one end of a poultry bone (85) and a stripper assembly (31) that is moved toward and away from the bone holder. The stripper blades (55, 56) engage the poultry part and stretch the meat, skin, etc., holding it taut while the thigh is moved through a cutting station. The stripper assembly is then moved away from the bone holder and then upwardly again to engage the bone and to strip the meat from the bone. As the blades strip the meat from the bone, the rotary bone holder is rotated by its sprocket engaging the sprocket (36) turning protrusions (45).
