Apparatus, systems and methods for improving strength of a thin glass member for an electronic device are disclosed. In one embodiment, the glass member can have improved strength by using multi-bath chemical processing. The multi-bath chemical processing allows greater levels of strengthening to be achieved for glass member. In one embodiment, the glass member can pertain to a glass cover for a housing of an electronic device.

The invention discloses an electromagnetic relay which resists electric repulsion force. When a relay contact is closed and the electromagnetic relay works, the relay is loaded, and a coil is provided with a setting signal. The current direction of a second leading-out sheet is opposite to the current direction of a movable spring, thus producing a magnetic field through the interaction. The magnetic field enables the movable spring to produce electromagnetic force. The produced electromagnetic force is in the same direction as the pushing force produced by a pushing card, thus increasing the contact pressure of a contact which is enough to resist the destruction of the electric repulsion force. The invention completely eliminates the technical problem that the electric repulsion force causes the contact to return easily in prior art. The invention further has the advantages of large resultant force of the electromagnetic force and the pushing force, small contact pressure of the contact, small contact resistance, reliable and stable electrical contact of the contact, capability of resisting short-circuit current, preventing the functional relay from being damaged, large switching power of the contact, capability of working under large load for long term, compact conformation, shock resistance, high impact capability, high capability of carrying load, low price, high manufacturability. In addition, the switching frequency of the invention shall not be too high, and the invention is applicable for streamlined production in large quantity.

The invention discloses a thermal-reversible self-repair polyurethane membrane and a preparation method therefor. Under protection of inert gases, 4,4-diphenylmethane diisocyanate, polycaprolactone glycol and N,N-dimethyl formamide are mixed uniformly, a reaction is carried out at a temperature of 50-60 DEG C, then the solution is cooled to a temperature of less than 5DEG C, 2-furan methylamine is added in the solution, the temperature is risen to 95-105 DEG C, the reaction is carried out for 10-11h, then hyperbranched polysiloxane with maleimide groups is added, the pre-finishing product prepared after the reaction is finished is poured into a die and dried, and a thermal-reversible self-repair polyurethane membrane is obtained. By utilization of the Diels-Alder (DA) reaction, thermal-reversible self-repair of a polyurethane membrane is achieved, the prepared polyurethane membrane has advantages of excellent thermal stability and high hardness, and raw materials have wide sources. The preparation method has characteristics of simple technology, strong practicality, wide applicability and the like.

The invention belongs to the medicine area, which involves a multi-emulsifier and a emulsion which be used by the multi-emulsifier and can resist high temperature and low temperature. This multi-emulsifier can combine by two or more then three emulsifiers. When combining, we can use two or more then three emulsifiers at will. The multi-emulsifier includes pharmaceutic adjuvant, oil and water. The emulsion includes drugs, oil phase, multi-emulsifier, the water and so on. The emulsion can be made after combining the oil and the water by isotropic device. The invention has some advantages: 1, the emulsion can resist high temperature and frost thawing. 2, easy to produce the average granularity smaller than the 150nm. 3, obtains the aseptic preparation without the high temperature. 4, produces the emulsion under the low pH value, so expand the application area. 5, increases the chemical stability of the medicine. 6, reduces the irritating quality.

A substantially rigid defibrillator carrying case having a hinged side, a latch disposed on a latch side opposite the hinged side, and a handle disposed on a handle side disposed between the hinged side and the latch side. The carrying case is constructed without protrusions and with a rigid handle, which combine to allow easy removal and deployment of the contents from a vehicle storage location to a cardiac arrest patient. The carrying case is further constructed for greater ease of use during rescue, greater ro-bustness, and for ease of maintenance.

Diesel engine exhaust filtration systems, and ceramic honeycomb wall flow exhaust filters for such systems, wherein the filters comprise axially centralized filter sections having a higher heat capacity and / or a higher gas flow resistance than peripheral filter sections disposed radially outwardly thereof, the filters thereby exhibiting increased resistance to thermal damage from filter regeneration over-heating.

An embedment tile with a replaceable upper plate and a lower plate joined by fasteners in a manner that permits replacement of the upper plate when desired. The embedment tile upper plate comprises a plate having a pattern of upwardly extending projections on its upper surface forming a tactilely detectable pattern.

A substantially rigid defibrillator carrying case having a hinged side, a latch disposed on a latch side opposite the hinged side, and a handle disposed on a handle side disposed between the hinged side and the latch side. The carrying case hinge is constructed for greater structural integrity when the case is open, and to have a flush-mount profile when the case is closed.
