Abstract: ABSTRACT OF THE DISCLOSURE   The exemplary embodiments relate to a device housing implantable in the body and having a reservoir for the infusion of fluid and having a conveying and dosing unit for conveying the fluid from the reservoir to the discharge opening of a discharge catheter.  In known devices of this type, the reservoir is held at a reference pressure which is lower in comparison to the pressure at the fluid discharge location in order, in case of a defect, to prevent fluid from flowing out.  According to the present disclosure, pressure equalization between the inside space of the housing and the environ-ment is effected for example by a hydrophobic or hydrophilic diaphragm with pores of a specific size or a diffusion diaphragm in combination with a pres-sure control valve in the wall of the device housing.

Abstract: SELF-PROPELLED ROTATING AERATOR            ABSTRACT OF THE DISCLOSURE      A substantially horizontally located pipe or arm extends upon each side of a central support which is mounted for rotation upon a vertical stationary spindle extending upwardly from the base of a liquid holding enclosure.  A pair of arcuately curved baffles are supported upon the pipe or arms in spaced relationship one from the other and compressed air is fed through a plurality of apertures or the like formed through the wall of the pipe and directed substantially horizontally.  This air is entrained in the liquid and the baffles guide the flow created by the dif-ference in specific gravity of the liquid with the entrain-ed air and the liquid alone thus causing the device to ro-tate in a direction governed by the curvature of the baffles or vanes.

Abstract: Abstract of the Invention Glass fibers reinforced polymeric polymers can be produced with high strength properties such as tensile strength, flexural strength and impact strength by using sized glass fiber strands of the present invention. The sized glass fiber strands have a residue of an aqueous sizing composi-tion comprising:  aqueous dispersible, emulsifiable, or solubilizable polyurethane polymer, polyepoxide polymer, polyethylene-containing polymer, and wax, where the weight ratio of the polyethylene containing polymer to the wax is in the range of about 25 to 1 to about 1 to 25, and one or more amino silane coupling agents.  In addition to the amino silane coupling agent, the sizing composition may have an epoxy silane coupling agent and/or a lubricant modified silane coupling agent.  The wax can be deleted from the composition, when the polyethylene-containing polymer has limited branching  The sized glass fiber strands can be produced by conventional forming process or by a wet chopped glass fiber forming process.

Abstract: Abstract of the Disclosure An on-line system for measuring the concentrations of additives applied as a coating to at least one surface of a moving web of material which may already contain the additives in which prior to the application of the coating the web is irradiated with x-ray radiation of a sufficiently high energy to cause the additives contained therein to emit fluorescent radiation.  In response to the emitted radiation a first radiation detector generates a first set of signals corresponding to the concentrations of the additives initially contained in the web.  Subsequent to the application of the coating both surfaces of the web are irradiated with x-ray radiation of sufficiently high energy to cause the additives contained therein to emit fluorescent radiation.  In response to the emitted radiation, second and third radiation detectors generate a second and third set of signals corresponding respectively to the concentrations of the additives applied to each surface of the web. The sets of signals are fed to a microcomputer which provides an indication of the concentra-tions of the additives initially contained in the web and subsequently applied to the web.

Abstract: A B S T R A C T    The present invention relates to a process for the production of N-substituted acrylic acid amides by conversion of 2-carboalkoxy-t-oxabicyclo(2,2,1)hept-5-enes with primary or secondary amines to 2-carboxamide-7-oxabicyclo(2,2,1)hept-5-enes and the thermal decomposition of the latter, preferably in the presence of Lewis acids and in a vacuum, to furane and N-substituted acrylic acid amides.  The process according to the invention results in high purity N-substituted acrylic acid amides that are, in the main, free of bifunctional monomers which would disrupt the subsequent polymerisation of the N-substituted acrylic acid amides by undesired cross-linking.

The primary and vent seals are spaced on opposite sides of the central axis at locations for reducing the side loading forces acting around the central axis as the container is moved.  An adjustable screw engages a spring for adjusting the pressure flow through the valve and the screw includes one or more metal washers on each side of a shoulder on the screw coated with low friction material whereby the shoulder can be easily backed off from engagement with the body.

Abstract: ABSTRACT            A pin for a fastener of the pin and swaged sleeve type which has a head and a shank.  The shank has a plurality of combination locking and break-neck grooves with each groove having first and second sidewalls and arranged to provide a cross-section of approximately V-shape.    The total angle included between the first and second sidewalls of each groove is less than the total angle included between the first and second sidewalls of each groove which is closer to the head.  This arrangement of grooves assists in ensuring that, when the sleeve has been fully swaged into the grooves and the tail of the pin is pulled, that the groove which is at the outer end of the swaged sleeve acts as a breaker groove.          This overcomes the problem in the prior art where it was not possible to predict which groove would act as the breaker groove.
