Abstract: Batch filtration is carried out within a rockable/rotatable housing, suspension to be filtered being fed in via ports in the upper region onto a curved filter fixed within the housing, and filtrate draining from below, via outlets to which vacuum may be applied. The housing is preferably cylindrical and may be mounted upon rollers or wheels so that rocking or rotating can be effected by belts or chains attached between the housing and a linearly reciprocable member, or by a rotary gear or friction drive wheel acting on the housing circumference, or by rack and pinion means, or a variety of other means. Washing of filter cake, reslurrying, drying by hot gases, and pressurization can all take place "in situ" whilst rocking continues, and discharge of cake is effected via the same ports as for inlet by turning the housing over.

Abstract: A system and device are disclosed for protecting the primary windings of a distribution transformer from surge current which exceed a predetermined level including a tank for accommodating the distribution transformer, a first arc gap extending between a first terminal and a second terminal on the secondary side of the distribution transformer, and a second arc gap extending between a third terminal and the second terminal on the secondary side of the distribution transformer. The arc gap being mounted within the gas space of the tank which accommodates the distribution transformer such that a surge current which exceeds the predetermined level is directed through the arc gaps and bypasses the secondary windings in order to protect the primary windings of the distribution transformer. The internally mounted arc gaps being effective when applied to either interlaced or non-interlaced distribution transformers.

Abstract: A bimetallic thermal release element (34) for use in a thermally actuated tripping mechanism, and in particular used in electrical circuit breakers (10) wherein the load current is passed through the bimetallic element has a self-aligning floating latch member (141) configured to engage the release member and to disengage therefrom when the bimetallic element bows a sufficient amount at a given temperature or current. The bimetallic element is preferably an elongated member supported at its ends (128, 130) by side members (28, 42). An increased sensitivity is imparted to the bimetallic element by mounting the side members for rotation to accommodate the bowing.

Abstract: An optical rotary encoder having a rotatable pulse scale having a row of code pattern with specific light-permeable or-deflection slits each for outputting a reference position signal and other light-permeable or reflection slits each adapted to reduce the amount of light for outputting an angular signal, both of the optical signals being photoelectronically converted and the waveform of the resultant electric signals being shaped based on threshold voltages into electric pulse signals indicative of a reference angle of 0.degree. and the accumulated angle of rotation, in which the circumferential width of each specific reference slit is made narrower than that of other slit so that the pulse width for angular position indicating of the angular pulse signal is always equal and constant for ensuring more accurate detection of the angle of rotation.

Abstract: A system for inspecting the ends of cigarettes prior to their packaging on a conveyor line. The system provides telecamera units which produce images of the ends of a group of cigarettes. A processing unit then analyses the brightness level of a given area on each cigarette end. The processing unit then counts the total number of areas having a brightness level within a given range and compares that number with that of a reference end image for determining the existence of defects. An expulsion unit is further provided for rejecting those groups of cigarettes which fall below the requirements of the reference end image.

Abstract: A means and method is described that uses a tissue excision (atherectomy) catheter system for creating a passageway through obstructive tissue in a blood vessel of a human body such that the passageway has a greater luminal diameter than the outside diameter of a percutaneously inserted catheter used to create that passageway. A guide wire is first percutaneously inserted into the blood vessel and advanced through the obstructive tissue. A percutanesouly inserted catheter is then advanced over the guide wire and it cuts through the obstructive tissue while the blood vessel is compressed at the site of the obstructive tissue by means of an externally applied pressure cuff. The compressional force on the blood vessel is then released and the catheter and guide wire are removed from the blood vessel. This procedure results in a luminal diameter of the passageway cut in the obstructive tissue that is larger than the outside diameter of the tissue excision catheter.

Abstract: "A Manufacturing Automation Protocol (MAP) interface unit couples a local area network (LAN) to a MAP network. The LAN includes a plurality of industrial programmable logic controllers (PLCs) and the MAP network includes a plurality of MAP devices. The MAP interface unit comprises a CPU for performing a plurality of routines. A first routine controls the coupling of the MAP interface unit to the MAP network and a second routine controls the coupling of the MAP interface unit to the LAN. A further routine disposed between the first coupling routine and the second coupling routine converts messages from the MAP devices on the MAP network to messages to the PLCs on the LAN and converts messages from the PLCs to messages to the MAP devices. These messages are either requests for data or responses with data to these requests.

Abstract: The power supply of the present invention is designed to operate over a wide range of both ac and DC input voltages and frequencies from 0-400 Hz. The power supply also provides two DC low voltage outputs, one for devices that do not require a high degree of regulation and one for devices that do require a high degree of regulation. The power supply also includes a power-up inrush clamp to limit high start up currents to approximately two times the nominal switching current. The primary switching transistor of the power supply is controlled by a dynamic feedback circuit which works interactively to increases the switching speed of the primary switching transistor.
