Abstract: A writing instrument comprising an elongated hollow housing and a refill having a writing tip at one end. A cap member (50) mounted on the opposite open end of the housing can be rotated to selectively position the writing tip between a retracted storage position and an operative writing position. A feed sleeve (30) accepts the end of the refill (11) and engages in a carrier head sleeve (24) projecting into the open end of the housing. The carrier head (20) is supported on the housing in a rotatable but non-sliding manner and the feed sleeve (30) is supported interiorly of the housing in an axially displaceable and non-rotatable manner. A built-in stamp carrier is hinged to the carrier head so that it can be pivoted around an axis perpendicular to the longitudinal axis of the writing instrument between a position approximately parallel to the longitudinal axis and a position approximately perpendicular to the longitudinal axis. The carrier head (20) mounts an O-ring around its outer circumference.

The mechanism comprises at least two coupling element (11, 12), each coupling element having a pair of radially outwardly directed spherical pivot portions (11', 12'). The spherical pivot portions of the coupling elements are housed in an intermediate element (8) comprising a continuous inner ring member (10) defining spherical pockets for the pivot portions and an outer ring (9) circumscribing the inner ring. The pivot portions (11', 12') are rotatable at least around their cardioids while being contained in pockets formed in the inner ring of the annular intermediate element (8), such that the one coupling element can swivel in one plane and the other coupling element can swivel in a plane perpendicular to the first relative to the intermediate element (8).

Abstract: A combination of a cap and tube in which a tube has an opening terminating in a tapered nozzle with an open end. The nozzle has a first diameter proximate said tube and is designed for rotational engagement with a cap. The nozzle includes a ring with a diameter which is the largest diameter of the nozzle and is located at least a band width distance from the junction of the nozzle to the tube. The cap is sized to engage the nozzle at its open end and has a closed outer terminal end. The outer end of the cap includes an axially centered locating cup for engagement with the outer open end of the nozzle. This forms a first seal in a first position and a second seal in a second position which is closer to the outer cap end by the band width distance. The cap is designed for rotational engagement with the nozzle. At its nozzle engaging end, the cap terminates with a circumferential band having an axial width defining the above mentioned band width distance.

Abstract: A device for holding an amount of magnetic fluid by means of a magnetic field inside a gap-shaped space located around a rotatable shaft, including a unit consisting of an annular pole piece whose inner circumferential plane is located at a relatively short distance from the shaft. The device has at least one annular permanent magnet for generating the magnetic field, whereby the magnetic fluid is kept inside the gap-shaped space between this unit and the shaft. The invention is characterized by the fact that the pole piece (3, 14) is located between two annular permanent magnets (1, 2; 12, 13), whereby the analogous poles of these magnets are directed at each other and the inner circumferential planes of the two magnets are located essential equidistance from the shaft (4, 11) in order to form, together with the shaft, two annular spaces which are located on both sides of an annular intermediate gap.

The tray bottom has a plurality of apertures in a predetermined pattern which are vertically aligned with the mat apertures such that drainage of condensation from the tray is facilitated.

Abstract: A ladder stand device for use with conventional ladders comprising a pair of spaced apart side channels aligned to be placed inward from the stiles of a ladder and a bottom step and a top shelf spaced from one another by the distance between every other rung on the ladder. The step and shelf each are pivotally mounted on the pair of channels near opposite terminals end thereof. The step and shelf each have rung engaging locking tabs for engaging a rung, with each lock tab combining with the channels to prevent movement thereof transverse to the ladder stiles. The step further including a hinge for adjusting positioning the step in a storage position parallel to the channels and a rung engaging position for use as a step. The shelf has a padded front side for engagement with a person standing on the step in the rung engaging position. The shelf further has a latch for adjustably positioning the shelf in a storage position parallel to the channels.

Abstract: A method of making a thermoplastic elastomer composition produced by dynamic vulcanization of SBR as a dispersed phase of cross linked SBR, and a co-continuous matrix of SEBS and polypropylene. The dynamic vulcanization step takes place under conditions of shear and temperature to reach the decomposition point of crosslinked SBR, at which time the crosslinking reaction is quenched. Compositions of superior properties are achieved using this method.
