Abstract: This document describes a speaker-integration system and associated devices and systems. The speaker-integration system includes a speaker that is re-workably mounted, via an elastomeric gasket, to an intermediate structure that is mountable to an outer enclosure of an electronic device. The intermediate structure forms a cavity in which the speaker is sealed, effective to use the cavity as the speaker's back volume to contain acoustic waves without impacting other structures in the electronic device. The front of the speaker is sealed against the outer enclosure by a gasket that controls, based on its placement and geometry, axial and radial directions of the speaker relative to the intermediate structure to prevent the speaker from buzzing against surrounding rigid parts. The speaker has wires that exit the back volume via a detachable grommet, which controls positioning of the wires to prevent rub and buzz against surrounding parts.

Abstract: A dispenser capable of dispensing a fluid via a vertically-oriented piezo device comprises a reservoir in the form of a replaceable cartridge containing a fluid to be dispensed, a planar piezo element having front and rear surfaces and which in use is oriented with its plane vertical and which is drivable to vibrate and thereby dispense fluid from the front surface, and a pump to draw a predetermined amount, or dose, of fluid from the reservoir and to drive the dose of fluid at a predetermined above-atmospheric pressure to the rear surface of the piezo element for dispensing.

Abstract: Automatic injection device includes a housing, a syringe, a plunger, and a syringe carrier. The housing includes a barrel. The barrel includes an elongated window to allow viewing of contents inside the housing. The syringe is disposed within the housing and has a reservoir. The plunger is at least partially disposed within the syringe and includes a visual indicator. The syringe carrier is disposed within the housing and configured to contain the syringe and displace the syringe within the housing between a first position and a second position. The syringe carrier has a first opening and a second opening. The first opening is configured to align with the window and the reservoir when the syringe carrier is in the first position, and the second opening is configured to align with the window and the visual indicator when the syringe carrier is in the second position.

Abstract: An injector assembly (100) includes a main body (102) having a first connecting arrangement, and a cap (104) having a second connecting arrangement for, in use, releasably connecting the cap to the first connecting arrangement of the main body. The first or the second connecting arrangement (120) includes an open neck portion (122) leading to a locating portion (124), at least part of the locating portion having a maximum width (120A) greater than a maximum width (120B) of the open neck portion. The second of the first connecting arrangement (108), respectively, includes a head portion (109) having a maximum width (108A) greater than the maximum width of the open neck portion.

Abstract: An insulator for beverage container includes flexible, insulating panels held together by elastic strips. The panels are held together to form a generally conical shape with an opening for receiving and supporting the beverage container. The elastic strips stretch to allow the insulator to expand to accept beverage containers of different sizes and shapes.

Abstract: An equine animal figure velocipede in the form of a tricycle, having a head member and front legs member fixably attached to a rod means so that the head and legs members rotate in parallelism about the front portion of the main body of the velocipede. A pair of transparent eyes with decorative decals are located on opposite sides of the head member, and an illuminating mechanism is provided inside the head which may be activated by switches on the rein bars on either side of the head.

Abstract: A process for producing bundles of high modulus polyethylene fibers for reinforcement in composites wherein the matrix is a brittle material such as cement, concrete, plaster of Paris or the like. The process involves passing high modulus polyethylene yarn through high pressure nip rolls to deform the individual filaments and to form a loosely adhering unitary mass or bundle of filaments which is then chopped into short lengths for use as fibrous reinforcement in composites. In a preferred embodiment, the yarn is twisted prior to being passed through the nip rolls.

Abstract: An improved overall process is provided for producing carbon filaments beginning with a multifilament acrylic precursor. The process facilitates the thermal transformation of the acrylic fibrous material in the absence of undesirable coalescence between adjoining filaments. An extremely thin deposition of colloidal silica initially is provided upon the surface of the multifilament acrylic precursor (as described), the fibrous material thermally stabilized in the absence of coalescence (as described), the colloidal silica substantially removed, and the thermally stabilized fibrous material carbonized (as described). The resulting carbon filaments exhibit improved physical properties and particularly are suited for use as fibrous reinforcement in a resinous matrix.

Abstract: A vertical pyrolysis furnace used in the carbonization or high temperature heat treatment of a continuous length of organic fibrous material is disclosed. The oven includes a central conduit or passage having a plurality of independently controlled heating zones disposed circumferentially therearound and spaced axially therealong. The conduit and heating elements are surrounded by suitable insulating material and a gas-tight shell. At the top of the furnace an exhaust manifold is provided which communicates with the central conduit. An environmental seal is provided at the upper end of the exhaust manifold and at the bottom of the conduit. Suitable gaseous inlets communicate with the furnace for an inert gaseous atmosphere which is controlled such that free convection causes the gaseous atmosphere to rise vertically through the central conduit to the exhaust chamber located at the upper end thereof.

Abstract: An improved process is provided for readily transforming a relatively low denier (i.e. 0.5 to 10 denier per filament) polybenzimidazole fibrous material to a carbonaceous fibrous material which contains at least 90 percent carbon by weight. The polybenzimidazole fibrous material initially is reacted with a solution of an acid (as described) to form a polybenzimidazonium salt, and the fibrous material subsequently is heated in a non-oxidizing atmosphere to form the carbonaceous fibrous material which retains the original fibrous configuration intact. A preferred acid solution for use in the present process is a dilute solution of sulfuric acid. The resulting carbon fibers are useful as fibrous reinforcement in the resinous or metallic matrix material.
