Abstract: A seal and closure member of elastomeric material adapted to be cast in situ and comprising a cylindrical body portion and an integral frusto-conical skirt therewithin. A radially outwardly extending flange is embedded in adjacent concrete. The skirt has a knock-out web at its smaller diameter end portion and the seal and closure member may thus be employed selectively as closure members for apertures in distribution boxes and the like and as seals for pipes in communication with the box interiors. The seal also includes integrally formed bosses which allow a baffle to be secured directly thereon on the interior of the box opposite the end of a pipe in the seal.

Abstract: A method and apparatus for modifying a spun yarn includes first storage or processing equipment for the yarn, subsequent storage or processing equipment for the yarn spaced some distance from the first storage or processing equipment, a path of travel for the yarn defined between the two sets of equipment, and a false untwister device located along said path of travel for imparting a false untwisting process to the yarn, the yarn subsequently reverting at least partly to the true twist originally present in the yarn, whereby the resulting yarn structure has a very much softer handle than was present prior to the false untwisting step.

Abstract: A splash bar fill assembly for a splash-type cooling tower includes a plurality of splash bars, each of which includes a one-piece elongated member having a generally convex upper surface of restricted width and also having first and second edges having a pair of converging side surfaces depending downwardly therefrom at an acute angle with respect to the upper surface.

Abstract: A rotary head assembly for use in a helical-scan magnetic recorder-reproducer includes a pair of magnetic head tips of single-crystal ferrite mounted on an axial end of a rotatable cylinder in substantially diametrically opposite relation to each other, each of the magnetic head tips having two tip members joined to each other through a mating interface and a surface for sliding contact with a magnetic tape. A body of a rigid adhesive is applied to an end of the mating interface remote from the surface. The rigid adhesive is highly rigid and substantially nonelastic for suppressing vibration. The rigid adhesive body attached to the magnetic head tip suppresses vibration of the magnetic head tip to reduce noise produced by the sliding contact between the magnetic head tip and the magnetic tape. The rigid adhesive body increases the rigidty of the magnetic head tip.

There is provided a mode switching means for setting the mode of the battery check system to the large current load check mode when said device is to be supplied with power from the battery pack and to the small current load check mode when said device is to be supplied with power through the D.C. plug.

Abstract: A device for holding a series of boiled food products and method for baking boiled food products including one or more carriages having pivotally mounted boards thereon for supporting the boiled food products. The carriages are positioned on a movable table adjacent to an opening of a rotatable oven such that each carriage may be disposed within the oven in successive shelves. Each of the boards of each carriage has a trip lever or handle movable between a first position, wherein the boiled food products rest on the boards in a generally horizontal position, and the second position, wherein the lever is rotated permitting the boiled food products to fall onto the shelf itself. A single carriage may also be repeatedly used in multiple shelves of the oven. The shelves of the oven each include a pair of spaced-apart guide rails which constrain lateral movement of the carriage when it is supported within the shelf.

Abstract: A magnetic disk assemblage rotatably housed in a magnetic disk cartridge comprises a center core which is cylindrical in shape and is provided with a floor, in the center of which is a hole for a drive shaft, and, at its upper edge, with a flange. The flange is provided with a plurality of small through-holes. For assembly, the cylindrical portion is inserted into a central hole formed in the magnetic disk, and the core and disk are fixed together by inserting instantaneous adhesive into the space between the lower surface of the flange and the upper periphery of the holes in the disk, via the through-holes.

Abstract: A sliding shutter for a magnetic disk cartridge is disclosed which includes an engaging member positioned to contact a torsion spring in the cartridge during the process of fitting the shutter onto the cartridge. The engaging member acts to guide the spring to the proper position for engagement and has an angled face to facilitate the movement of the spring into engagement in a notch in the engaging member. This also reduces the rate of product rejects caused by springs which are mis-positioned during the assembly process.

Abstract: A device for use in setting of fractured wrist or other wrist disorders including a rigid rod member adjustable in length, a pair of holders fastened to the member and each carrying at least one transcutaneous pin which is intended to penetrate the skin and muscle so that the free ends of the pins may be secured in holes drilled in the bone parts.

The pin adapted for entering the bone distal the fracture is operatively connected to a compound arc gear adapted to move the wrist through a predetermined path of flexion or extension. The compound arc gear has a plurality of sections each of predetermined varying radius of curvatures to correspond to the physiologic path of flexion or extension of the patient fitted with the device.

Abstract: A magnetic recording disk comprises a disk base which is provided with a central opening and an annular recess formed on at least one side thereof between the inner peripheral edge portion surrounding the central opening and the outer peripheral edge portion along the outer periphery of the disk base, and a flexible magnetic sheet which has a shape conforming to the shape of the disk base and is bonded to the disk base over the annular recess along the inner peripheral edge portion and the outer peripheral edge portion. The disk base is formed by injection molding of plastic material using a mold having a cavity provided with a central core for forming the central opening in the disk base and an annular protrusion which is coaxial with the central core and encircles the central core on the radial outside of a pin gate or pin gates through which molten resin is injected into the cavity so that an annular groove encircling the central opening is formed coaxially with the central opening.

The thickness of the portion of the disk base corresponding to the annular recess is larger at the outer part than at the inner part.

Abstract: In a magnetic tape wind-up system for winding up a magnetic tape into a roll shape around a wind-up core, a feed direction of the magnetic tape to a tape roll, which is formed by winding up of a preceding portion of the magnetic tape, is controlled by a position control roller before the magnetic tape arrives at the tape roll. The position of the magnetic tape in the tape width direction is controlled by an edge control roller at a position where the magnetic tape arrives at the tape roll. Air between turns of the magnetic tape in the tape roll is discharged by pushing the magnetic tape against the tape roll by use of a push roller while the magnetic tape is present at the outermost circumference of the tape roll.

The gripper head is receivable into the first transverse opening and has a front end, a rear end, an upper end and a gripper tooth near its front and upper ends for gripping the glue stick.

Abstract: Anti-static material is bonded to the portions of a magnetic tape cassette which are in close proximity to the magnetic tape when the tape is in motion. The anti-static material prevents a static charge being generated by frictional contact between tape and cassette, and therefore protects the tape from damage and erratic travel speed.
