Abstract: ABSTRACT OF THE DISCLOSURE           One or more breakable cartridges containing a two component resin system are inserted in a bore hole drilled in a rock formation be an elongated roof bolt.  An expansion shell assembly is positioned on the end of the bolt and includes a shell formed by a plurality of bendable fingers surrounding a camming plug.  The camming plug is threadably engaged to the end of the bolt.  A clip member is non-rotatably secured to the shank of the bolt and extends into one of the longitudinal slots that separates the fingers of the shell.  After the cartridges and bolt are advanced into the bore hole, the cartridges are compressed between the end of the bore hole and the end of the bolt and fractured to release the resin components.  The clip member non-rotatably secures the shell to the bolt and prevents relative rotation between the camming plug and the bolt so that the bolt may be rotated in a counterclockwise direction to effect mixing of the resin components in the bore hole before the shell is expanded without threading the plug off the end of the bolt.  The mixed resin flows downwardly in the bore hole and fills the voids between the shell and the wall of the bore hole.  Before the resin hardens the bolt is rotated in a clockwise direction to disengage the clip member from the shell to permit downward advancement of the camming plug on the bolt to expand the shell.  The cured resin filler increases the engagement of the shell with the wall of the bore hole and thereby reduces the slippage of the expanded shell in the bore hole to thus maintain the tension on the bolt.

Abstract: ABSTRACT OF THE DISCLOSURE   This invention is an energy conversion system that utilizes the rhythmic swell of the ocean, converting this energy into mechanical energy and thence into the generation of electricity.  The mechanical energy is in the form of fluid compression by pistons inside vertical cylinders that are inter-connected with floats that ride up and down as external sleeves on the cylinders.  The float motion is induced directly by the ocean swell and produces the piston stroke.  The fluid compressed by the plurality of piston and cylinder units drives a power output generator through a controlled means.  There is a return line system of the fluid to the cylinders. Means are provided to anchor the cylinders to the ocean bed.

Abstract: ABSTRACT: "Shaving apparatus"                The invention relates to a shaving apparatus having a shear plate with hair entry apertures and a drivable cutting unit with at least one cutting element provided with a cutting edge.

In order to eliminate this drawback a con-struction is proposed in which the cutting element is provided with a hair pulling element which leads in the direction of the driving and which is immobile relative to the cutting element.

Abstract: ABSTRACT OF THE DISCLOSURE     Disclosed is a disposable contraceptive in which a first member engages the vaginal vault and a second member, secured to the first member, engages and closes the cervical open-ing.  The first and second members are substantially discoid, with the second member smaller in discoid area than the first.          The second member is a generally impermeable sponge-like material which is lubricated to aid in adhesion and closure of the cervix.          The first member is generally resiliently closable so that the overall dimension of the contraceptive may be reduced in size for insertion into the vaginal vault.  The first member is defined at least by opposed anterior and posterior portions which engage the respective anterior and posterior portions of the vaginal vault. the second member is coupled or joined to the first member at the posterior portion.        In one embodiment, the second member is a sponge joined to a film.  The film is held in position to define the first discoid member surface by a rim.        In other embodiments, the first and second members are resiliently joined at the posterior portion so as to urge the second member into positive engagement with the cervix.  Thus, a finite resilient nylon filament is bent into a figure 8 and covered with a soft, yieldable, foam plastic covering.  By folding at the intersection of the upper and lower loops, the contraceptive is formed.  In another example, a liner of resilient plastic in the shape of conjoined circles is covered by a soft, flexible, plastic envelope.  In yet another example, an annular discontinuous rim is covered by a foam plastic.  The rim has an integrally formed tongue extending therein and about, to which may be secured (by any well known means) a sponge-like impermeable plastic second member .
