A glove is equipped with a mouthpiece containing an air passage. The mouthpiece allows the wearer to puff air into the space between the glove and the skin of the hand. The puffed up glove is much easier to doff and don than a conventional glove. A puff-off wetsuit glove for use in underwater activities is described in detail.

This invention is generally directed to a process for the preparation of chalcogenide alloys of the elements of Groups VA to VIA of the Periodic Table, in high purity, (99.999 percent) which comprises providing pure esters of the alloys desired, and subsequently simultaneously subjecting the esters to a coreduction reaction. The esters can be obtained by treating the corresponding oxides with an alcohol of diol. Examples of alloys produced in accordance with the process of the present invention include selenium arsenic, selenium sulfur selenium tellurium, selenium tellurium arsenic, selenium sulfur tellurium, and the like.
摘要:
There is disclosed a method for the preparation of a homogeneous, physically stable dispersion of colloidal metal particles of a transition metal selected from the group consisting of ruthenium, rhodium, osmium and iridium, having a size in the range of from about 10 Angstrom units to about 200 Angstrom units. The method comprises preparing a solution of a functional polymer in an inert solvent, and incrementally adding thereto a transition metal cluster compound at a temperature at which the transition metal cluster compound will become bound to the polymer and thermally decompose to produce elemental transition metal particles, the process being carried out in an inert atmosphere. Such dispersions may be used per se as catalysts, or may be used for the preparation of supported colloidal transition metal catalysts. The dispersions may also be used for the preparation of ablative optical recording media.

There is disclosed a method for the preparation of a homogeneous, physically stable colloidal elemental iron dispersion of colloidal iron particles having a size in the range of from about 10 Angstrom units to about 200 Angstrom units. The method comprises preparing a solution of an active polymer in an inert solvent, and incrementally adding thereto an iron precursor, at a temperature at which the iron precursor will become bound to the active polymer and thermally decompose to produce elemental iron particles, the process being carried out in an inert atmosphere. Such dispersions may be used per se as catalysts, or may be used for the preparation of supported colloidal iron catalysts. The dispersions may also be used for the preparation of ablative optical recording media, and for the preparation of magnetic xerographic developer materials.

The present apparatus is intended for use with a timer for controlling a process having an operating cycle including a plurality of sequential operational steps and for providing at least one preselectable output signal for each such step. The apparatus includes an activator for initiating the execution of a test cycle by the timer, and a test cycle step incrementor for selectively incrementing the timer so as to permit the rapid verification of both the operation of the timer and the accuracy of the output signal for each step.
摘要:
A method and apparatus is disclosed for injecting a temperature sensitive probe into a tire to be cured in a mold which is at least in part heated by a steam cavity. The probe is utilized to monitor cure conditions and provides an electronic input signal to control the cure. The probe is carried by a movable member in a housing mounted in the mold with one side of the movable member being exposed to, and thereby worked on, the steam in the cavity so that the steam pressure itself is utilized to inject the probe.
摘要:
An apparatus for controlling sequence and duration of the operational steps in processes such as vulcanization of a pneumatic tire is capable of operating under two basic modes or parameters. In one mode the operational steps are dictated by elapsed real time, while in the other mode, the operation can be dictated by elapsed cure equivalent factors. The desired length of each step or the cure, whether in time or cure equivalents, is set into an input program means. In the time mode, time generating circuitry provides an output proportonal to elapsed time which output is displayed on a counter and electrically compared with the information in the input program means. When a match occurs, the time generating circuitry and displays are reset and the input program means directs the tire vulcanization press to perform the next sequential function. Also disclosed is circuitry which is capable of performing secondary functions such as extending the length of a step, as necessary. If it is desired to operate in the cure equivalent mode, a signal proportional to elapsed cure equivalents is developed by a cure equivalent generating circuitry which performs digital integration of the Arrhenius function. The input to cure equivalent generating circuitry can be a signal proportional to tire temperature developed by internal thermocouples or can be a signal which is directly proportional to the Arrhenius function as generated by a thermistor sensor.

A display module comprising a display assembly bonded to a substrate. The display assembly comprises a first side for displaying visual information and a second side. The second side comprises a first area having an adhesive layer and a second area having a through connection to a conductive pad. The substrate comprises a first side for receiving the display assembly. The first side comprises a first surface area for bonding to the adhesive layer and a second surface area comprising an electrode pad having multiple electrodes for receiving electrical signals. A conductive elastomer is positioned within the through connection establishing conductive continuity between the conductive pad and the electrode pad when the display assembly is bonded to the substrate.
