Abstract: A method is disclosed for limited write downs of data from higher security classification users to lower security classification users across computer networks, while preserving the security of classified data at the higher security classification user from covert transmission via acknowledgment messages from the higher user to the lower user. The intended acknowledgment message is released to the lower user when it matches the user content of a predicted acknowledgment message. In TCP/IP interface applications, the acknowledgment messages are IP based data transfer protocols acknowledging the transfer of data from the lower side to the higher side. With IP datagram transfers, deterministic portions are predicted and non-deterministic portions are identified. Where the number of non-deterministic bits exceed a predetermined rate, the acknowledgment message is discarded.

Abstract: A clip is described for making connections to the leads of an IC device whose leads are very closely spaced, which can be constructed reliably and at low cost. The clip includes a flat cable (112, FIG. 8) mounted on a clip frame (44), the cable having parallel conductors (114) mounted on a continuous insulative film (116), with lower portions of the conductors exposed to serve as lead-engaging contacts (50). The film is thin in a lateral direction (154) to easily bend and allow differential deflection of the contacts, while the conductors are thick in a lateral direction to minimize the influence of the film on conductor deflection. The frame of the clip has a cavity (46) with side and end walls that closely align with the body (14) of the IC device without an interference fit thereto. A pair of pivoting arms (34, 36, FIG. 2) press against the opposite ends of an IC device to lock the clip but not to align it. A contact arrangement that includes the flat cable, includes a header ( 122, FIG.

Abstract: The present invention is a high pressure quick connector especially for use in connecting brake lines of a vehicle. The connector includes a housing which selectively receives a tube retainer cap. Retaining means such as a garter spring or snap ring allow for a low force insertion of the cap into the housing with an very high pull-off force. The cap is used to trap a tube with a bead upset, and the tube may be removed after the cap is unlocked. A second way of releasing the tube includes the use of a tube retainer plug selectively received in the cap, the upset trapped between the plug and cap. The plug can be removed while the cap is still locked in the housing, releasing the tube. A release tool may be used to unlock the cap from the housing. An insertion indicator ring is used to establish the locking of the cap within the housing. A dust boot prevents contaminants from interfering with the operation of the connector.

Abstract: A connector is described, of the type that has a plastic housing with pegs (15, FIG. 2 ) that project through round holes (16) in a circuit board to hold the connector in place, wherein the pegs are shaped to minimize warping of the circuit board and facilitate construction of the pegs. Each peg has an axis (27) and has at least three vertical interference ridges (17-20) each spaced from the axis by slightly more than the radius of the circuit board holes, with the outer surface (28) of each ridge having about the same radius of curvature as that of the board holes. The outer surface of each peg preferably extends by an angle A of at least 15.degree. about an imaginary circle (32) centered on the axis, with the ridges connected by straight sides (21-24), with the straight sides lying on an imaginary regular polygon such as a square (29). Each peg can have a cylindrical lower portion (30, FIG. 4 ) extending below the ridges and closely received in the hole to assure alignment of the ridges with the hole.

Abstract: An electrical connector assembly includes two connectors (22, 24), wherein the first connector has a pair of contacts (46A, 46B, FIG. 9 ) which rapidly break engagement as the connectors slowly approach each other. An actuator (60), has a ridge deflector (72) for moving back a contact end portion (52A), the actuator being urged rearwardly (R) by a first spring (100). However, a pair of rearwardly bowed trigger springs (82) press against surfaces (96) to resist rearward (R) actuator movement. As the connectors progressively approach each other, the first spring (100) is progressively compressed, causing increasing deflection of the middles of the trigger springs (82), until resistance offered by the trigger springs suddenly decreases. The actuator then moves rapidly rearward, so its deflector (72) moves back the contact end portion (52A) to rapidly open the switch. The actuator is rapidly moved back by the now-compressed first spring (100).

Abstract: Apparatus is provided for connecting rows of contact pads on a leadless integrated circuit (22, FIG. 1 ) to rows of traces on a circuit board (24), which facilitates the connection and which facilitates substitution of a probe for the integrated circuit. The apparatus includes a socket (32) forming a largely rectangular cavity (34) which closely receives the integrated circuit (22), the socket having a lower portion with elongated slots (51-54), each slot holding an elastically compressible interface device (60). Each interface device has a row of compressible conductors each having an upper end engaging a contact pad (26) on the integrated circuit and a lower end engaging a conductive trace (30) on the circuit board. With the socket securely held to the circuit board, the socket can be used to hold a probe (220, FIG. 13 ) with a probe board (222) having contact pads (224) on its lower surface that can lie at the same locations as the contact pads on the integrated circuit when it lies in the socket.

Abstract: A lockable electrical connector is provided with two connector halves, and a locking device which includes at least one pin on one connector half and at least one receiving sleeve on the other connector half. The pin embodies an annular securing groove and the receiving sleeve is provided with a circumferentially extending slot. In the mated condition of the connector halves, a transversely displaceable slide extends through the slot in the sleeve into the securing groove in the pin to lock the connector halves together.

Abstract: The invention relates to a contact breaker of the type that includes a slider (22, FIG. 1) that slides longitudinally within a housing to allow a moving contact 50 (FIG. 3) on a sudden actin bimetal strip (44) to pass through a slider opening (62) against a fixed contact (40), or to keep the contacts apart after they have briefly moved apart. The state of the contact breaker is indicated by a signalling electrical circuit which includes a moving contact (80, FIG. 1) mounted on the slider and having a pair of clips that connect coplanar signalling contacts (68, 70). The slider has a lower extension (92, FIG. 4) that prevents arcing between power contacts. The housing includes two half-casings (16, 18, FIG. 7) joined at a longitudinal joint 19, one carrying power terminals (32, 34) and the other carrying signalling terminals (74, 76). The slider keeps the contacts (50, 40, FIG. 3) separate even if the front housing surface is blocked.

Abstract: In a two-stage reaction device for vacuum brake boosters, the clearance at the piston rod will be reduced by the piston rod acting directly on the valve piston which comprises a head portion connected via a neck portion at its end close to the vacuum chamber. The head portion and the rear end surface of the valve piston contain abutment surfaces which cooperate with levers. The levers, in turn, are moved by the push rod coupled to the master cylinder via a fork-like shaped pressure member with prong-shaped attachments. In this arrangement, one end of each lever is held resiliently between a supporting ring and a spring plate, with the supporting ring including edges about which the levers are tiltable when the pressure member acts on the other ends of the levers.

Abstract: The hydraulic brake system having at least one wheel brake is adapted to be pressurized by a master brake cylinder actuated by a hydraulic power booster. An auxiliary pressure is adjustable in a pressure chamber of the hydraulic power booster by means of a brake valve. Interposed between an auxiliary pressure source and the brake valve is a pressure-reducing valve that is controllable by the auxiliary pressure and contains a valve controlling a passageway, the valve being acted upon by the auxiliary pressure to open the passageway. To simplify the construction of the pressure-reducing valve, the closure member of the valve is exposed to the reduced pressure in the pressure-reducing valve such that a force related to the valve seat surface will be exerted on the closure member in the closing direction of the passageway of the pressure-reducing valve.
