Abstract: A sealing device for containers which forms a valve for automatic elimination of overpressurized gases that may form with the container is provided. The device is composed of a rigid cap having a flat crown and depending skirt, an elastic disk sector in contact with the underside of the flat crown and an inner cap having a circular crown with a circular cutout and raised circular rim on an upperside thereof. A flat circular protuberance on the underside surface of the disk sector, when the device is in use fits into and is surrounded by the circular crown portion, both of which are adapted to fit vertically over the orifice of the container. When in use, the circular crown exerts a crushing pressure on the upper portion of the elastic disk sector while at the same time the flat circular protuberance remains sufficiently elastic to allow gases overpressurized to vent from the container.

Abstract: A very slim and generally compact card reader for use with a so-called "smart card", i.e. having an integrated circuit connected to external contact pads to enable stored information to be read. A carriage (3) is slidably mounted in a chassis (2) and an abutment (4) supports and guides the card as it is inserted into the reader. Card reading contacts (13a) are supported by a plinth (13b) which is spaced from the card (1) when the carriage is in an initial card receiving position (see Figure 4a). Insertion of a card into the reader causes the carriage to slide along a lazy Z-shaped path (8) generally in the direction of card insertion towards a final card reading position (see Figure 4b) and the carriage thus presses the card against the abutment (4) causing the card to bend so that the contact pads are urged into engagement with the contacts on the plinth. Deflectable fingers (11,21) on the carriage or the chassis grip the card and help to maintain both the card and the carriage in the card reading position.

Abstract: The separation and/or purification of products, e.g. biomaterials, by liquid-liquid extraction in an aqueous system is enhanced by introducing particulate polymeric adsorbent, e.g. ion exchange resin, into the extraction system and agitating the system, whereupon the adsorbent reversibly binds the product, or material to be separated from the product, to form a complex, and the complex preferentially partitions into one of the liquid phases. The complex is then separated, and the product recovered from the complex or the remaining liquid.

Abstract: FIBER OPTIC ROTATION SENSING SYSTEM AND   METHOD FOR BIASING A FEEDBACK SIGNAL    OUTSIDE A REGION OF INSTABILITY  ABSTRACT OF THE DISCLOSURE A closed loop fiber optic rotation sensing system prevents the occurrence of instabilities in its feedback signal by modulating the counterpropagating waves with a reference signal and demodulating an electrical signal indicative of the phase difference of two counterpropagating waves with the reference signal. The modulating means is driven to null the phase difference between the counterpropagating waves, and the feedback signal is adjusted to prevent instability. The counterpropagating waves may be either phase modulated or shifted in frequency. The means for modulating the counterpropagating waves may comprise a fiber optic frequency shifter connected to the fiber optic sensing coil and means for applying the reference signal to the frequency shifter. The feedback signal is adjusted with either a pseudo-random or a periodic signal having a zero mean value to prevent instability.

Abstract: MULTIPLE QUEUE BANDWIDTH RESERVATION PACKET SYSTEM Abstract A multiple queue packet bandwidth reservation arrangement is disclosed in which statistical type packets are scheduled for transmission and a prescribed interval is reserved for transmission of periodic type packets for each scheduled statistical packet. Each arriving statistical packet is assigned a scheduled time of service based on the amount of packet information already queued to be supplied as an output and the duration of any intervals reserved for transmission of periodic packets at an assigned output port. Operation of the bandwidth reservation arrangement is such that normally a statistical packet is not delayed from being transmitted at its scheduled time of service for more than an interval needed to transmit a maximum length periodic packet.

Granted: 2001-10-09
Abstract: An injection mold for use with a molding press has four mold levels in axially stacked relation, permitting a substantial doubling of output for a given size of press as compared with a back-to-back two level stacked mold. The mold feeder flow path extends axially from the injector head to a flow distribution block located at the centre of the stacked mold block series. The centrally located distribution block is connected, in use isolation, sealed relation with the injector head, being axially displaceable therefrom in contin-uing sealed relation upon the opening of the mold. A drool prevention valve system, located at two of the mold inter-faces, to preclude drooling of fluid plastic stock upon open-ing of the molds includes pressure fluid actuators for operat-ing the valves, wherein the pressure fluid may comprise the fluid plastic stock. The valve system also includes a de-pressurizing valve provision, wherein, upon opening of the mold interfaces the stock distribution passages are substan-tially depressurized, to thereby reduce any tendency to drool.      The mold includes axial adjustment means to compensate for differential variations in overall mold length within the press, due to changes in effective mold temperature.
