Abstract: A known procedure is used to prepare liposomes of bipolar lipid membranes which are permeable and hence "leak" their contents at a rate which is variable by choice.  The liposome is supplied with medication or cosmetic material for the oral cavity, or specifically for the teeth and gums.  The liposome is then attached to a molecule that has affinity for the hydroxyapatite. Thus, the liposome will bind to oral cavity hydroxyapatite and bathe the surrounding support surface with its contents for extended hours of service.

Abstract: ABSTRACT OF THE DISCLOSURE      A collapsible ramp comprising an attachment frame, a foldable support structure mounted to the attachment frame by pivotable hinges, and a telescoping deck structure of interconnected, essentially rectangular plates.  The foldable support structure has longitudinal support members with foldable joints intermediate along the lengths of the members, and these members are pivotally connected to the hinge means.  The ramp can be formed into an extended state in which the longitudinal support members are extended outwardly from the attachment frame and the rectangular plates of the telescoping deck structure are extended and supported on the support members.  Alternatively, the ramp can be formed into a collapsed state in which the support members are folded back on -themselves using the foldable joints and folded inwardly pivoting about the hinges so that the support members are housed within the attachment frame, the telescoping deck structure being retracted to cover the folded rails on the attachment frame.

Abstract: Vacuum sizing device has a modular construction consisting essentially of sets of pairs (32) of upper and lower sizing elements arranged end to end to define a passageway (26) having a cross-sectional shape and size corresp. to that required for a plastic extrusion (24) from a die (22). The elements are clamped between upper and lower backing members (20,30) held together by T-headed bolts (76). In order to maintain the extrusion (24) in close contact with the internal walls of the sizing elements, the walls are broken by strategically placed vacuum openings which merge within the element bodies and open into vacuum chambers. These chambers have screw threaded ports communicating with the exterior which can be connected to a vacuum source by couplings (50). The elements also contain cooling chambers through which a cooling fluid can be circulated for cooling the extrusion. The vacuum sizing device is for sizing extruded profiles such as PVC window frames. By using a modular structure, the mfg. costs of the device are considerably reduced as the element pairs are relatively small, identical pieces of metal which are ideally suited for computer controlled machine tool mfr. Also, the device can be dismantled and transported and cleaned with ease.

Abstract: A container closure formed in its closed state of a springy, elastomeric plastic, to be snapped onto the neck of a container with a ring-shaped retaining portion (2). The retaining portion (2) is connected via a hinge (10) to a re-closable lid (3). A tear-off strip is formed in the join between the lid and the retaining portion in the area opposite the hinge (10). The strip (4) is defined by scoring (6, 7) to diminish its strength. A seal is provided in the join between the lid (3) and the retaining portion (2), in the circumferential sections between the hinge (10) and the ends of the tear-off member (4), said seal being in the form of material bridges (5) spaced around the circumference of the closure. The tear-off strip (4) extends along approximately half the circumference of the closure and is connected with substantially rigid joins between the lid (3) and the retaining ring (2) so that the closure can be pressed onto the neck of the container without the material bridges (5) being broken. When the lid (3) is opened at the hinge (10) and the bridges (5) are thus broken, substantially by pure tensilw stress, an accoustic signal will be obtained if the bridges (5) were unbroken.
