A multi-function tool (10) includes two channels-shaped handles (12, 14) having a first side wall (22) and a second side wall (24) forming a channel therebetween.

In addition, a channel (130) is formed in the first end of the piston.

The groove (7) is surrounded by a circular channel (2) which is also recessed.

At least some of the delivery ports are located along the channel.

A quick access closure apparatus including a reusable bottle and lid that secure together The bottle has at least one protrusion and the lid has a channel and ridge

The rest of this surface is occupied by a groove, which gives attachment to the Subclavius; the coracoclavicular fascia, which splits to enclose the muscle, is attached to the margins of the groove.

A mating plate (20) of a wet-type friction engagement device is composed of more than four axially split annular plates having spline teeth (26).

The upper groove width (Wu) is greater than the lower groove width (Wl).

In an alternate arrangement, the groove may include a compressible support arranged between the insert and an end of the groove.

Means are provided for attaching the tongue means within the groove in one of the panels of EPS and attaching the groove means within the groove of the other panel of EPS.

To fabricate a joint in a panel (10), a groove (18) is generated and the panel is bent along the groove.

The grove also has an upper side wall adjacent the surface, the upper side wall being substantially perpendicular to the surface and defining an upper groove width (Wu).

The smaller flute (22) is a finishing flute and set behind the roughing flute (23).

Each flute is asymmetric with respect to an innermost point of the flute surface.

A first flute surface has a greater slope than a second flute surface.

Each flute has a cutting edge (54).

The first cutting flute includes a first cutting edge and the second cutting flute includes a second cutting edge.

In that way, a sheet having an upper corrugation can easily be turned around a lower corrugation, until a tight contact has been provided between the corrugations.

The crushing disks (13a) with the fine corrugation (18) have a smaller diameter than the crushing disks (14a) with the coarse corrugation (17).

A fluted filter medium (74) comprising a corrugated filter sheet, where each flute (120) has an end closure defined by a regular fold arrangement in the corresponding corrugation.

A tube for a heat exchanger provided with a helical corrugation, wherein the helical corrugation has pitch and a width, and the width being at least 20% of the pitch, such that an improved heat transfer is achieved.

The free edge of the upper corrugation can be bent outwards or inwards to form the hinge.

The flexible spline has a spline length, LS, and LS ≤ LG.

The input coupling includes an outer spline engaged to the inner spline of the gear.

A blank spline without teeth may replace the cutting spline.

In yet another preferred embodiment the spline element (28) is a solid reinforcement spline element.

A spline engagement ring (32) contains a spline of one set (36, 38) on its O.D. and a spline of the other set (30, 34) on its I.D..

At its deepest point, the furrow is connected to a fitting for tapping the maximum pressure.
