Abstract: ABSTRACT OF THE DISCLOSURE           This invention relates to a novel apparatus adapted to feed to a mold from an extruder, a plastic synthetic material containing a foaming agent.  The apparatus comprises a channel for transporting the material from the extruder to the mold, a nozzle having an opening therein, the nozzle forming a part of the channel, a nozzle needle which is moveable through the nozzle opening, the front surface of the needle adapted to close the nozzle opening, a heating element which maintains the needle at a high temperature, a cooling system which maintains at least a part of the inner surface of the channel at a temperature below that of the needle, and a carrying means adapted to open and close the opening by moving the needle.          The apparatus of the present invention provides a simple and inexpensive device for use in an injection molding process for charging a mold, producing a stream of synthetic material which at the exit of the nozzle and at the entrance to the mold has an outer limiting zone which does not foam, and in the central region of the stream, foams in the normal way.  These devices have hithertobefore been unknown.

Abstract: INTRAVENOUS FEEDING PUMP FAILURE ALARM SYSTEM     Abstract The present invention relates to a failure alarm system for an intravenous feeding pump in which the pumping force is secured by the projection or a plunger into a chamber filled with the liquid to be pumped, which plunger is encased in a tightly fitting sheath of elastic material.  In such a pump, actuation is secured by the application of a force from an actuator to the end of the plunger extending without the wall of a pumping chamber and the return force is secured by the elasticity of the sheath.  The actuator of such a pump provides an actuator which can be selectively set to provide an extended range of operations per unit of time and can be modified to control the amount or projection into the pumping chamber by the plunger.  In such a combination means is provided by the present invention for sensing the fact that there is a negative pressure,or suction, in the system that is not balanced by the in-flow of liquid, i.e., the amount or fluid delivered to the pump for each operation is less than that required by the setting (thus sensing when a supply is shut off, or less than the preset amount of liquid is reaching the pump).

Abstract: ABSTRACT OF THE DISCLOSURE A method and apparatus are provided for maintaining the conductance of liquid crystalline compositions comprising pure trans-stilbene liquid crystalline materials at a level sufficient to allow dynamic scattering of the composition. Thus, there is provided an electro-optic device including an electro-optic member that comprises a layer of pure liquid crystalline composition between two electrodes.  The liquid crystalline is a pure trans-stilbene nematic liquid crystal-line material.  A source of ultraviolet radiation that is electrically energizable is positioned to impinge the layer with radiation upon energization.  Electrically connect-ed with the member are comparison means for comparing the electrical resistivity of the layer with a predetermined resistivity value and for generating an electrical signal when the layer resistivity is greater than the predetermined resistivity value.  Electrically connected with the compari-son means and the energizable source of ultraviolet radiation are energizing means which receive the electrical signal and, upon receipt thereof, energize the  source of ultraviolet radiation.

Abstract: ABSTRACT OF THE DISCLOSURE In a magnetic memory storage device an enclosure is provided to contain the disk pack assembly and the recording head carrying arms, the enclosure being adapted for supplying filtered cooling air, thus eliminating heat generated in the operation of the equipment; and for reducing temp-erature gradients between the components within the enclosure.  The spinning disks of the disk pack act as a centrifugal air pump and a shroud forming part of the enclosure is spirally shaped to increase the air flow through a sized air inlet thus reducing warmup time.  This basic flow pattern is enhanced by the addition of two lesser air flow patterns, from above the pack and from below the pack around the drive spindle, so that an excess of cool incoming air does not contact the disks, thereby balancing top inlet air with bottom inlet air to control air movement.

Abstract: MULTIPACKAGING DEVICES                        ABSTRACT    Multipackaging devices made of a resilient plastics-material such as low density polyethylene. The devices are made in strip form and are integrally interconnected longitudinally of the strip for continuous machine application to adjacent rows of containers with selective transverse severance of the applied strip to form individual packages of selected members of containers. The strip comprises a row of bands along each side thereof with intersecting and diagonally arranged substantially straight-line band segments extending between the side bands. The band segments cooperate with each other and with the side bands to define additional intermediate bands between the side bands. The strip is substantially narrower than the width of the rows of containers so that substantial transverse stretching of the strip is required to apply the side and intermediate bands to the rows of containers. In the strip the band segments cooperate with the side bands so that transverse stretching forces need only be applied to the side marginal edges of the strip to expand the strip for application to the rows of containers. That cooperation may be defined as resulting from an isotropic arrangement wherein upon application of stretching forces on either side of the strip an isotropic pattern of expansion occurs to give an unusual and unexpected result.

Abstract: ABSTRACT OF THE DISCLOSURE          The invention provides an improved accumulating conveyor having a frame with a plurality of roller carriages mounted transversely.  Each of the roller carriages comprises a pair of spaced end portions and a connecting portion connecting a lower part of these end portions.  A pressure roller is rotatably mounted in a lower portion of each roller carriage, and a con-veyor roller is rotatably mounted in an upper portion, parallel to and spaced from the pressure roller.  An endless belt is mounted on the frame, and is positioned to pass between the pressure rollers and the conveyor rollers, the belt having a thickness less than the distance between the conveyor and pressure rollers. The belt has  a thickened portion which has a thickness at least equal to the distance between the pressure and conveyor rollers, so that passage of the thickened portion causes rotation of these rollers.  An intermittent drive force is thereby delivered to the conveyor rollers, and the presence of an article on the conveyor, or the movement of an article along the conveyor, causes the roller carriages to tilt into engagement with the drive belt.  Stoppage of articles on the conveyor causes the carriages to tilt into a rearwardly tilted position, thus causing an accumulation of the articles.
