Abstract: PILOT OPERATED RELIEF VALVE          Abstract A pilot operated relief valve for use on medium and high pressure vessels, conduits, and the like.    A two-stage, non-flowing valve (5) operates a main relief valve (7) of substantially greater capacity. Flow control elements provided by (35), (36), (38), and (39) associated with the first stage poppet are utilized to provide positive valve operation.  In a preferred embodiment the main valve is mounted directly onto the pressure vessel which is to be vented at a predetermined pressure.  The pilot is preferably mounted closely adjacent to and in fluid communication with the main valve.  A flow adapter (100) having a self-cleaning orifice is disposed intermediate said main valve head volume (68) and pilot vent port (1) to provide improved operation of the combination.  A ball (16) selector, (24, 15, 76) provides means for conveniently connecting to a field testing either the pilot or the entire valve, providing improved setpoint and reset or blowdown adjustments for the overall combination.    A single stage proportional pilot valve (131) operates main valve (7) to provide pressure relief flow corresponding to the degree of over pressure (Ref. FIG. 16).  A partially pressure balanced large diameter poppet (142), and reduced diameter seals 145b provide increased sensitivity to over pressure, improved setting accuracy, and poppet stability. A ball closure arrangement, (154) (158) acts to conserve test gas.

Abstract: ABSTRACT      The disclosure describes a system for ordering and pairing feature boundary intersections on a sweepline of a simulated digital radar visual display screen in order to arrange a variable length list of data in accordance with a desired order.  This ordering and pairing system resolves the correct range order of the intersection pairs for any closed feature shape regardless of boundary convexity, range inaccuracy or possible shape anomalies.  The system includes an input data control means (11) having one input connection and a plurality of output connections (14, 16, 18) to store the input data temporarily.  There is described two sorting pipelines (12, 13) connected to two of the output connections to receive certain described "key" data in order to sort the data in each respective pipeline in accordance with a desired correct relationship of ranges. A temporary storage means (19) is connected to receive the "non-key" data.  Finally, a merge logic circuit (32) receives the outputs from the two pipelines (12, 13) and attaches to each of the "key" data that appropriate "non-key" data.

Abstract: ABSTRACT OF THE DISCLOSURE A rotary joint is provided which is particularly useful in deep-sea diving suits, and which can be construc-ted in such a way such that resistance to rotational move-ment or the potential for leakage, does not increase sub-stantially with external pressure on the joint.  Preferably, the joint has a sealing member, a retaining member, and a central member disposed axially between the sealing and retaining members.  The central member has an annular first end dimensioned and axially slidably mounted on a retaining end of the retaining member so as to define a first variable volume chamber therebetween.  The central member also has a second end with inner and outer extending annular bearing members, each concentric with, and normally rotatably abutting a corresponding sealing surface portion on the sealing member, so as to define annular side walls of a second chamber.  The second chamber is interconnected with the first chamber.

Abstract: ABSTRACT OF THE DISCLOSURE           Aqueous alkaline solutions containing ferric chelates of alkalenepolyamine polycarboxylic acids (e.g. EDTA) have been used to remove plated copper from freshly cleaned ferrous metal surfaces.  Normally, an oxidant is added during the copper removal stage to oxidize dissolve ferrous ion to the ferric state. This process is improved by adding aqueous hydrogen peroxide to the flowing cleaning solution such as the solution EMF (platinum or iron versus a saturated calomel electrode), as measured at about 80°F (26.6°C) and at a solution pH of about 9.2, becomes more positive than - 250 mV in about one hour.  The quantity of hydrogen peroxide used can vary, but about 1.12 pounds (.508 Kg) of commercial 35 percent hydrogen peroxide for every pound of dissolved iron in the cleaning solutions gave excellent results.

Abstract: PERSONAL IDENTIFICATION SYSTEM                  ABSTRACT OF THE DISCLOSURE        A personal identification system comprises a generator which generates an Offset Number which is recorded on the mag-netic stripe of a card, together with the account number (PAN) of the person to whom the card is to be issued.  The generator stores   transformed digits of a sequence of digits (IN) which have been secretly entered by one or more officers of the card-issuing institution.  To generate the Offset Number the PAN is entered and transformed before being stored to initialize a first feedback shift register.  The person to whom the card is to be issued enters a chosen alphanumeric sequence (PIN) secretly known only to him.  The PIN, after undergoing trans-formation is stored to initialize a second feedback shift register.  When both registers have been initialized they are reinitialized by different parts of different digits of the transformed IN.  Different digits of the two registers are used to initialize a control feedback shift register which when reaching a selected state in its cycle of states controls the generator to generate the Offset Number, based on a selected mapping of the digits,then present in the first and second feed-back shift registers.  To use the card it is entered into a verifier.  Therein the PAN and Offset Number on the magnetic stripe are read out.  The  intended user enters a PIN, and the verifier,like the generator,generates an Offset Number.       Only if the PIN entered into the verifier is identical to that entered into the generator, does the verifier produce an Offset Number identical to that read off the card, thereby indicating that the card user is the one to whom the card was issued.

Abstract: APPARATUS FOR MOVING AN ADHESIVE APPLICATOR An adhesive applicator for applying an air-curable adhesive to sheets of paper has a nozzle that normally is located in a storage position with the end of the nozzle inserted into a liquid in a sump. This prevents adhesive material in the end of the nozzle from drying out or caking and thereby clogging the end of the nozzle.

Abstract: ABSTRACT            The invention concerns monitoring large structures to detect defects, e.g. cracks. An electric current is impressed on a steel structure (31, 32) equipped with contact points (41-45) between which are measured voltage drops caused by the impressed current. A relatively large number of fixed contact points are used all over the area which is to be monitored. The voltage drops are measured between selected pairs of contact points and these voltage drops are compared with corresponding voltage drops having been measured previously in the same manner when the structure was in an initial condition, preferably without any defects. Such monitoring is mainly applicable on oil drilling rigs and petroleum production platforms for exploitation of oil and gas fields offshore, where it is important that the monitoring can be performed by means of robust and simple devices resistant to the prevailing arduous enviroment.
