Abstract: Abstract of the Disclosure A back-washable filtering element, especially for use with pumps, and more particularly for use with pumps that handle liquids with solid material entrained therein, consists of a helical coil spring disposed in a flow path for the liquid to be filtered.  A movable element in the flow path is mechanically connected to the spring and compresses it axially under the effect of the back washing liquid to automatically reduce the flow capacity.  The resultant "shrugging" of the spring also permits it to clear itself of filtered material to facilitate the back-washing.

Abstract: Abstract of the Disclosure A guide rail or track system for guiding test tube holders or racks from one station to another. e.g., in a mono-channel analyzer, for presenting test tubes in such holders in sequence to one or more servicing operations at a plurality of stations.  The rail system, for example, may comprise a main linear guide rail along which a holder ?ving a row of test tubes supported therein is adapted to be moved longitudinally stepwise to present each test tube in the holder in sequence to a given station, or a given position therein, where an operation is to be carried out with respect to each test tube as it is presented in the station.  Arranged at right angles to the main rail, one or more branch rails leading to or from other service stations are provided at spaced intervals and the main rail at each juncture or intersection of these rails is constructed to allow a lateral shift of the holder (which is also specially constructed to allow such shift) to or from the main rail respectively from or to the branch rail along which the holder moves laterally, i.e., the lengthwise dimension of the holder extends across the branch rail at right angles, or perpendicularly, to it as the test tube holder moves along the branch rail.  Such a branch rail may terminate at a junction or intersection with another or subsidiary rail or guideway along which the holder moves longitudinally in a direction parallel to the main rail.  Means is provided for moving the holder along the main rail and means is provided at the junction of a branch rail with an intersect-ing rail such as the main rail, for laterally shifting the holder from the junction.  One aspect of the invention is the novel rail system for transporting test tube holders in analytical instruments. Another aspect is the novel con-struction of test tube holders or racks for functional cooperation with the rail system.

Abstract: DEVICE FOR COMPENSATING SYNCHRONOUS DISTURBANCES        IN THE MAGNETIC SUSPENSION OF A ROTOR                         ABSTRACT         A rotor is carried by radial electromagnetic bearings each having an associated detecting device which, through a servo-circuit, governs the current to the windings of the bearing to maintain the rotor in a predetermined position.  To combat synchronous disturbances, the servo-circuit includes a filter which rejects frequencies in a narrow band centered on a frequency corresponding to the speed of the rotor.  By using conversion circuits slaved to the rotor, the system operates for any rotor speed.

Abstract: VIEWING APPARATUS FOR MICRODOCUMENTS                      Abstract of the Disclosure A compact microimage viewing apparatus is disclosed which utilizes a low intensity light source with wide-angle projection optics to provide a clear and highly illuminated image to the viewer.  To achieve compactness, the high bright-ness light-distributive screen of the viewing apparatus is located at an acute angle to the axis of projection of the pro-jection lens.  Keystone distortion of the projected image is substantially eliminated by employing a correcting lens, preferably a Fresnel lens, between the screen and the viewer at a predetermined angle to the screen such that the image portion projected onto the edge of the screen nearest to the projection lens, which would otherwise appear smaller to the viewer than would the image portion projected onto the fathermost edge of the screen, is magnified to an extent that a rectangular and substantially non-distorted image is presented to the viewer.

Abstract: ABSTRACT OF THE DISCLOSURE     A thermally actuated disconnect coupling includes a coupling shaft normally connected between a drive member and a driven member to transmit torque from the drive member to the driven member.  Within the driven member, a fusible element such as a eutectic pellet supports the coupling shaft against axial movement during normal in-service use of the coupling.  Providing the connection between the coupling shaft and the drive member are axially straight splines formed both on the coupling shaft and the drive member.  At the other end of the coupling shaft, helical splines formed on the coupling shaft and the driven member provide means whereby torque is transmitted through the coupling shaft to driven member.  The axial length of the helical splines is greater than the axial length of the straight splines.  When the pellet is melted, such as by overheating, an axially directed component of the force transmitted by the helical splines propels the coupling shaft away from the drive member thereby disconnecting the drive and driven members.

Abstract: Abstract An attachment for a fishing line which comprises an elongated sinker of two parts which lock onto a fishing line.          The interior of the sinker contains pressure pads which lockingly grasp the fishing line.  A hinge formed of the sinker material connects the two portions of the sinker together with the hinge having sufficiently small area so that a user can open the sinker with thumbnail force yet the sinker retains sufficient force to securely hold the line therein.  The exterior of the fishing line sinker comprises an elongated member having a streamlined shape.  The sinker body can be mounted on the fishing line so the sinker body remains symmetrical with respect to the fishing line to thereby produce a weedless sinker that is always in alignment with the fishing line.

During the limbing and topping operation a bed of limbs and trees is formed on which the limbed trunks may be deposited, thereby keeping the trunks out of the mud, and hence clean, and minimizing the chances of the trunks freezing in the ground.  The pile of limbed trunks is formed closer to the road than the pile of full trees to facilitate pick-up by on-road equipment.

In contrast, the known clay analog of equivalent treat-ment gels the mineral oil but not the synthetic polyolefin lubricant under comparable conditions.
