Abstract: ABSTRACT The present invention provides a process for the manufacture of a polyethylene film having improved tear strength in the transverse direction. The process involves extruding a partially crosslinked polyethylene into film having a thickness between 10 and 100 µm, by a blown film process. The blow-up ratio is in the range of 1.2:1 to 4:1 and the MD draw-down ratio is in the range of 2 to 60. Polyethylenes used in the present invention had prior to being partially crosslinked a density in the range of 0.940 to 0.970 g/cm3 and a melt index in the range of 0.2 to 15.0 g/10 min. The poly-ehtylene is crosslinked to an extent sufficient to provide a film having an Elmendorf tear strength in the transverse direction substantially less than the tear strength of film made from the uncrosslinked polyethylene. Crosslinking may be accomplished using any known method e.g. by irradiation, through use of crosslinking agents.      The film so produced is useful in packaging operations where transverse cutting or tearing per-formance of the film is important.

Abstract: ABSTRACT:            In optical communication systems as well as in video disc playback equipment, it is necessary to position a (semiconductor) laser at an exact distance from a first lens of the optical system coupled to the laser. The exact distance between the laser and the lens is realized by arranging the laser in a bush-like cover on which a holder provided with the lens, is arranged with a press fit. The desired exact distance between the laser and the lens is adjusted by relative compression between the cover and the holder. Because the walls of cover and holder which are pressed together with the press fit are covered with a layer of indium, the walls  will slide smoothly one over the other during adjustment to the desired distance.

Abstract: ABSTRACT OF THE DISCLOSURE         A clothes washing machine of the type having recirculation of water from a tub into a perforated basket within which the clothes are received with a mechanically delayed action clutch driving both the agitator during wash and rinse cycles, and the basket during spin cycles.  The mechanical delay in the case of the wash or rinse cycles enables a recirculation pump to bring the water level in the basket to the operating level after the machine fill prior to initiation of agitator drive.  In the case of the spin cycle, the water level is reduced by a drain pump during the delay interval prior to initiation of the basket spin.  The mechanical delay is introduced by a retarding action on the centrifugal drive clutch whereby after start of rotation of the drive motor, the full engagement of the centrifugally actuated clutch is delayed by a rotary damping action consisting of a washer caused to rotate through a volume of silicone liquid enclosed in a container.

Abstract: A B S T R A C T           A multi-purpose carrier for external attachment to a land vehicle, said carrier conceived for carrying objects which are too large or cumbersome to carry inside the vehicle. The carrier comprises a retractable platform which holds the objects, wherein the platform is rotatably pivotable through two separate movements; one such rotational movement being about an axis which is parallel to the longitudinal front-to-rear central axis of the land vehicle, and this latter rotational movement the carrying platform is lowered at an angle with one end juxtaposed adjacent the ground near the vehicle, so that an inclined plane is formed to facilitate the loading movement of the object onto the platform from the ground; and from this latter inclined position the carrying platform is then rotated upwardly to a level position for the carrying position.  The other rotational movement of the carrying platform is about a transverse axis which is perpendicular to the longitudinal front-to-rear central axis of the vehicle. This latter rotational movement is used to tilt the platform, when empty, into an up-right vertical position adjacent the side of the land vehicle for storage positioning when not used.

Abstract: 48,231 ABSTRACT OF THE DISCLOSURE          This  invention  is  related  to  the problem of eliminating high carrying arcs at the contacts of electric control  devices  that  causes  pitting  at  the  contacts, reduces  contact  life,  and  limits  current  interrupting capabilities.  The object of this invention is to elimin-ate current arcs at the contacts by using permanent magnet means to pull the arc or stress the arc away from the contact thus eliminating it.  This invention uses a novel approach of utilizing multiple magnetic arrangements with magnets placed on a movable member which moves with the movement of the contacts as they go from one operating po-sition to another, thus changing and varying the strength of the magnetic field across the axis of movement of the contacts thereby pulling and stretching the arc away from the contact and thus eliminating current arcs that reduce contact life.
