摘要： A ply placement device uses a ply guide to place plies on a curved substrate surface. The ply guide includes a guide surface and a guide edge that are each curved to match the contour of the substrate so that the ply transitions smoothly from its planar form to a curved form as the ply is placed onto the substrate. The ply guide may be flexible or segmented to allow reconfiguration of the guide surfaces to match various substrate contours.

摘要： A sample changer for powder X-ray diffractometry includes a cylindrical dispensing container for holding a stack of pre-test sample holders, a cylindrical receiving container for holding a stack of post-test sample holders and a changer arm which automatically picks up the topmost sample disk in the dispensing container and rotatably positions the sample disk on the sample holder stage of an X-ray diffractometer for analysis. After analysis, the changer arm removes the sample holder and releases it into the receving container. The sample holders have a circumferential groove which coacts with semi-circular rotatable cams positioned on the distal end of the changer arm to enable the changer arm to lift and place the sample holders.

摘要： An ignition diagnostic monitor detects ignition malfunction. A first monostable multivibrator is coupled to an ignition module to receive the ignition signal and maintain a first logic state for a predetermined first time constant after detecting an ignition signal. The monostable multivibrator maintains a second logic level state after passage of the predetermined time constant until detection of another ignition signal occurs. The second logic level indicates a missed ignition signal and an ignition fault. A control module is coupled to the ignition module and the monostable multivibrator and receives a fault detection signal from the monostable multivibrator.

摘要： An improved drive for a magnetic data storage tape is described which features direct coupling of the tape from a machine to a file reel without interposition of vacuum buffers or spring loaded tension control devices. Control of the current supplied to motors driving the file and machine reels is performed by a microprocessor in response to information derived during an initialization routine performed at first mounting of a reel of tape upon the drive and in response to continuously generated velocity information generated by tachometers on the motor shaft. The absolute position of the tape can at all times be known to the microprocessor and the tension of the tape can be controlled by control of the supply of current to the motors. In a preferred embodiment, a solid state buffer memory is provided to accept data from a host computer during the time the tape drive comes up to speed. By use of the initialization routine to determine motor losses, windage, brush and bearing wear, and the moment of inertia of the motor/reel systems, and the instantaneous tachometer data, direct sensing of tape tension can be avoided, thus eliminating mechanical parts in favor of sophisticated electronic control means.

摘要： A compact and highly reliable proportioning pumping system for supplying a precise and controllable mixture of concentrate and water in a kidney dialysis machine comprises a central body and a pair of oppositely mounted pivotable linkages coupled to the body. A first pivotable linkage is coupled by connecting rods to a water metering piston and a concentrate metering piston respectively, a variable stroke ratio being provided by a signal actuated drive coupled to the linkage mechanism and controlling the relative position of the end of one of the connecting rods. The change of position is advantageously effected so as to maintain a precise proportionality between the flows delivered by each of the pistons throughout their variable stroke lengths. The range of proportioning adjustments can be mechanically limited and alarm conditions can readily be detected. Precise delivery of surge-free flows of liquid for subsequent mixing is enhanced by controlling flow through each piston with a fast-acting metering valve system. A bistable switching valve responsive to the limit positions of the first linkage mechanism controls an actuator piston to operate a second pivotable linkage mechanism to which the metering valves are coupled. The second linkage switches rapidly between two alternate valve positions, so that there is a minimum dead zone and both water and concentrate flows are precisely controlled.

摘要： A ratcheting pulley device is shown and described. In one embodiment, the device includes a sheave rotatably mounted in a housing. The housing defines an opening for ingress and egress of a rope or cord into the housing and around the sheave. The device includes a releasable ratchet mechanism, which, when engaged, permits rotation of the sheave in one direction but not the other, and which, when released, permits free rotation of the sheave. A loading-disk is mounted on the exterior of the housing and is in rotational communication with the sheave. The loading-disk allows rope or cord to be operably and quickly loaded into the device.
