Abstract: An attached storage media link has a self-timed interface (STI) in which a clock signal clocks bit serial data onto a parallel, electrically conductive bus and the clock signal is transmitted on a separate line of the bus. The received data on each line of the bus is individually phase aligned with the clock signal, providing a high speed, cost effective interface to a direct access storage device.

Abstract: A railway rail support assembly (3), for resiliently suspending a railway rail (1) above a track foundation (2) at discrete locations along the rail (1), has rail supporting means through which a predetermined clamping load is exerted on the said rail (1) such that the assembly (3) has a desired resistance to longitudinal creep therethrough of the rail (1). The rail supporting means are preferably attached, when the assembly (3) is in use, to an approximately horizontal upper surface of the said track foundation (2). Such an assembly (3) may be provided by first and second brackets (31, 32) and first and second elastic members (33, 34). Each of the said first and second brackets (31, 32) has a bearing part (312, 322) and a base part (311, 321) (311, 321), the bearing part (312, 322) being located adjacent to either sides of the rail (1) when the assembly (3) is in use and the base part (311, 321) being located on an upper surface of the said track foundation (2).

Abstract: An implantable defibrillator, which may include cardioversion and pacemaker capabilities, which has EMI filters which are not susceptible to defibrillation shocks and which reduce or eliminate the effects of charging noise on sensing circuits used for continuous confirmation. A first filter capacitor is provided between a sense electrode, which may include pacing capabilities, and a ground reference within a hermetically sealed can containing a pulse/shock generator. A second filter capacitor is provided between a sensing/pacing reference electrode, which may also be a high voltage or shock electrode, and the ground reference. In addition, there is a third filter capacitor between the ground reference and the can. Preferably, the connections of the first, second and third filter capacitors are physically as well as electrically adjacent to each other. The filter capacitors are housed in the can and in or adjacent to a feedthrough assembly which passes through the can.

Abstract: In a test system, test fixtures that hold modules are controlled to enable an operator to separate modules that pass a test from modules that fail. When a module under test is properly loaded in a test fixture, a test fixture controller instructs a tester to start a test procedure. For a semiautomatic test fixture, a test start command is automatically supplied to the tester when the test fixture is closed around the module under test. The test fixture controller automatically interprets the test results provided by the tester. The module that passes the test is automatically released from the test fixture. If the module fails, the test fixture controller keeps it locked in the test fixture. The module is released only when an operator presses a failure acknowledgement button on a control box.

Abstract: A resilient rail-fastening clip has a first straight portion (11) for locating the clip in a clip anchoring device (2) when the clip is in use, a second bent portion (12), a third heel portion (13), a fourth bend portion (14) and a fifth toe portion (15). When viewed such that lower most points of the first and fifth portions (11 and 15) of the clip lie in a horizontal plane, proceeding from the first portion (11), the second portion (12) appears to bend up out of that plane towards and then away from a vertical plane passing through the fifth portion (15). The clip (1) is used in an assembly including a baseplate (2) having a non-vertical stop (21d) on its shoulder (21) up which the clip (1) slides during installation until brought to rest through friction at a desired height above the rail (3).

Abstract: In an assembly for use in fastening a railway rail to an underlying rail foundation, a resilient railway rail fastening clip (1, 2,3) has at least one portion (1a) which when in use bears on, and extends substantially parallel to, a flange (301) of an adjacent railway rail (300), and retains an insulator (13, 13') for electrically insulating the clip (1, 2, 3) from the rail (300) when in use. The insulator (13) is held in engagement with the clip (1, 2, 3), which has a rail bearing portion of substantially circular cross-section, such that it can rotate about the longitudinal axis of the said rail bearing portion (1a). Unlike the prior art the insulator is self-aligning on the rail flange (301) when the rail (300) moves. One insulator (13, 13') disclosed has at least two load bearing surfaces (13a), such that it may be rotated so as to present an unworn load bearing surface (13a) to the rail flange (301).

Abstract: A multi-image detector assembly has an array of detector elements formed upon a single focal plane and a plurality of focusing members, each focusing member focusing a substantially identical scene upon a corresponding one of a plurality of sections of the array. An optical element such as a spectral or polarizing filter is disposed within a plurality of the optical paths of the focusing members, preferably proximate the focal plane. Image detection occurs continuously and simultaneously so as to provide a spatially and temporally correlated set of separate images utilizing the single focal plane.

Abstract: In a gate, a stile (20) and rail (21) abut side face to end face and are held together by a bolt passing at right angles through the end face to pull against a plate (25) located in a slot (26). Straps (34,41), see FIGS. 11 and 13, are used to reinforce the hanging and shutting stiles (20,20A) and to carry hanging and latching parts. A latching mechanism, see FIGS. 13 to 16, includes a latching bar (43) that is pivotally connected to the shutting stile (20) towards its middle by a flange (44). A leaf spring (45) urges the bar (43) into a latching position at which, when the gate is shut, the bar (43) is caught behind upper and lower retainers (46) mounted on a shutting gatepost (48). By pulling on a handle (50), the bar (43) can be rocked free of the retainers (46) to permit the gate to be opened. Connector plates ( 31) having sharp tongs are used, see FIGS. 9 and 10, with bolts to connect reinforcing struts (30) to the upper and lower rails (21,21A).

Abstract: A disposable instrument is adaptable for use in electrosurgical operations, such as, coagulation procedures used in blocking off fallopian tubes, and is characterized by having an improved electrode and switch assembly which permits interchangeable but permanent mounting of electrodes of a selected length and configuration within a handle grip. The electrodes conventionally may be of a type having normally spaced-apart tips which through actuation of a plunger disposed for extension through the handle grip will cause the tips to be brought together to grasp or surround the tube or other tissue to be coagulated. The interchangeable but positive connection of electrodes within the housing brings them into direct electrical connection with electrical contacts and specifically in such a way that the connection and mounting of the electrodes cannot be disturbed or broken.
