Abstract: TRAVELING BELT FILTER     ABSTRACT OF THE DISCLOSURE     A system for filtering contaminated liquid comprises a filter box submerged in a tank of contaminated liquid and provided with a perforate surface in its top wall. A conveyor-driven endless loop filter belt encompasses the filter box, with the pump-induced or static pressure differential between the tank and the filter box causing liquid to flow downward through the belt into the inlet opening. Control means are provided for automatically indexing the filter web in response to an excessive build-up of filter cake over the filter box inlet. The longitudinally extending edges of the filter web are held downwardly against the filter box by a chain which is selectively advanced with the web-driving chain by means of flight bars extending through the links of both chains. In one embodiment of the invention, the filter box is also provided with an inlet opening in its bottom wall, to increase the filtration capacity, and means are provided for resiliently biasing the hold-down chain upwardly against the longitudinal edges of the lower reach of the filter web, to prevent liquid from by-passing the filter web. A further embodiment of the present invention is adapted for the additional use of a disposable filter media, interposed between the endless loop filter web and the hold-down chain.

Abstract: 6560    INVENTORS: J?RG MUGGLI and PETER M?LLER CAN         INVENTION: FIRE ALARM     ABSTRACT OF THE DISCLOSURE     A fire alarm is provided with a temperature sensitive element formed of a shape memory alloy, which following cold working, upon heating to a critical temper-ature, typically for instance about 70°C, returns  to the original impressed shape and also retains this shape even after subsequent recooling.  Due to the movement of the element there is triggered a self-holding alarm signal, either directly by closing contacts or indirectly.  Resetting of the fire alarm can be accomplished by mechanically cold working the element, or by using two way-shape memory alloys and cooling to a lower temperature threshold which can be below room or ambient temperature.  A further beneficial construction is realized by combining the arrangement with a different type of fire detection or sensing element, for instance by arranging a shape memory alloy element in a scattered radiation-smoke detector.  Upon reaching a critical temperature, the shape memory alloy element moves into the radiation region, or when used in an ionization fire alarm, the shape memory alloy element screens the radioactive radiation source and reduces the ionic current.  Suitable shape memory alloys are, by way of example, nickel 55/titanium 45/ or nickel 45/titanium 45/copper 10.

Abstract: ABSTRACT OF THE DISCLOSURE          This invention relates to an integral heated probe for plastic injection molding and a method of making the same.          The probe has an elongated steel outer body with a cylindrical well extending to a pointed tip end.  An electrical cartridge heater member positioned in the well with the leads extending out the open end.  The space adjacent the pointed tip end and all around the cartridge heater is filled with copper to improve heat transfer between the heater member and the outer body. The copper fusing is performed by two-stage heating in a vacuum furnace.  First a slug of copper is inserted into the well and heated to melt it into the pointed tip end.  Then the heater member is inserted into the well through a sleeve of copper at the top and heated to melt the copper.  The copper flows down around the heater member and fuses to it, the outer body and the previously inserted copper.  Melting the copper under a partial vacuum ensures that the copper flows into all the spaces displacing the air and fusion bonding to the heater member and the outer body to improve heat transfer between them.

Abstract: ABSTRACT OF THE DISCLOSURE           The present invention is directed to a method and appar-atus for centrifugally separating substances of different atomic weights.  The substances to be separated are positioned in an evacuated vessel which has a longitudinal axis.  A magnetic field is generated in the vessel parallel to the longitudinal axis of the vessel and a target comprised of the substances to be sep-arated is positioned within the vessel at one end thereof.  A collector is positioned at the other end of the vessel.  Pulsed laser energy is focused on the substances to be separated thereby fully ionizing at least a portion of the substances and forming a plasma therefrom.  Immediately following the focusing of the laser energy, a current is passed through the substances to be separated which causes further full ionization of the substances and thereby the formation of additional plasma.  The ionized plasma is rotated and moved from the substances which are to be separated to a collector by the application of the magnetic field.          At least a portion of the ionized substances are separated by the centrifugal force resulting from the rotation of the plasma by the magnetic field.

Abstract: AN EFFECTIVE ERROR CONTROL SCHEME   FOR SATELLITE COMMUNICATIONS                      ABSTRACT            A hybrid scheme for controlling transmission errors in digital data communication systems.  Normally, data blocks with a small number of parity digits for error detection are transmitted.  When the presence of errors is detected, the retransmissions are not the original data blocks but some properly selected blocks for correcting errors in those erroneously received data blocks which are stored in a buffer at the re-ceiver.  The retransmitted blocks are formed based on the original data blocks and error-correcting codes with an invertible property.  When such blocks are received, they are used to recover the original data blocks either by an inversion operation or by a de-coding process.
