Abstract:
A hydrosilylation process is used to prepare a polyorganosiloxane having clustered functional groups at the polyorganosiloxane chain terminals. The ingredients used in the process include a) a polyorganosiloxane having an average of at least 2 aliphatically unsaturated organic groups per molecule, b) a polyorganohydrogensiloxane having an average of 4 to 15 silicon atoms per molecule and at least 4 silicon bonded hydrogen atoms for each aliphatically unsaturated organic group in ingredient a), c) a reactive species having, per molecule at least 1 aliphatically unsaturated organic group and 1 or more curable groups; and d) a hydrosilylation catalyst. The resulting clustered functional polyorganosiloxane is useful in a curable silicone composition for electronics applications.

Methods of producing a multiferroic thin film material. The method includes the steps of providing a multiferroic precursor solution, subjecting the precursor solution to spin casting to produce a spin cast film, and heating the spin cast film. The precursor solution may include Bi(NO3)3o5H2O and Fe(NO3)3o9H2O in ethylene glycol to produce a bismuth ferrite film. Further, the thin film may be utilized in varied technological areas, including memory devices for information storage.
Abstract:
A composition includes a siloxane of the formula: (RMe2Si01/2)a(MeRSi02/2)b(RSi03/2)o(Si04/2)d wherein a is at least 2, b is from 3 to 20, c is from 0 to 10, d is from 0 to 10, and each R is independently of the formula -CR'2-CR'2-Y-Z or -CRVCRVZ, wherein each R1 is independently a hydrogen atom or a Ci to C1O hydrocarbyl free of aliphatic unsaturation so long as at least one R' is a hydrogen atom, Y is a divalent organic group, and Z is a polycyclic group containing at least one aromatic ring.. A method of making the siloxane includes charging (HMe2SiO i/2)a(MeHSi?2/2)b(HSi?3/2)c(Si?4/2)d, a platinum catalyst, and an alkene of the formula CR2=CR-Y-Z or CR2=CR-Z into a reactor to form the siloxane. The siloxane is useful as a component in holographic storage media for photopolymer-based holographic data storage applications. The siloxane exhibits excellent compatibility when mixed with a polymerizable component before the polymerizable component is cured. Furthermore, the siloxane exhibits excellent diffusion from polymers of the polymerizable component after partial and complete curing. The siloxane also has a high refractive index while maintaining the excellent compatibility and diffusion properties when mixed with polymerizable component.

Abstract:
The present invention relates to a body bag. In a preferred embodiment, the body bag comprises a tray for receiving a corpse, a flexible, planar flap member [30] for covering the tray and a re-closable closure means [32] for sealing the corpse within the body bag. The tray has a raised circumferential rim [20] formed by walls with curved corners. The tray has two lengths and two widths. The flexible flap member [30] is connected to one length of the tray. The re-closable closure means [32] is connected to the peripheral side edges of the flap member [30] and to the rim [20] of the tray. Advantageously, each width of the tray has a high arched-shaped rim wall to permit the tray to accommodate a bulky corpse; and each length of the tray has a low rim wall to permit easier loading of the corpse on to the tray. In use, after the corpse has been loaded on to the tray, the flexible flap member [30] is maneuverable to cover the tray, and personnel can manipulate the closure means [32] to close the body bag to contain the corpse.
Abstract:
The present invention relates to a body bag. In a preferred embodiment, the body bag comprises a flexible unitary planar member and a closure means (32) for closing the body bag. The flexible unitary planar member has an outer surface, an inner surface, curved comers, peripheral side edges, an elongated central portion and a wing portion (36) connected to each length of the central portion. The planar member is symmetrical in shape with two halves about an imaginary midline axis. The closure means (32) is connected to the peripheral side edges of the planar member. The closure means (32) is operable to connect the peripheral edges of the two halves together to form the body bag enclosure.
Abstract:
The present invention relates to a body bag (20). In a preferred embodiment, the body bag (20) comprises a single flat member (30) having a central portion (34) and two wing portions (36), an outer surface, an inner surface (28) and peripheral side edges; and re-closable closure means (32) connected to the peripheral side edges. The flat member (30) is made of a flexible sheet material that comprises at least one layer of a fluid impermeable material. In use, the body bag (20) is opened and its central portion (34) positioned to overlay a bed. The wing portions (36) are folded and packed. The patient rests upon the inner surface (28) of the central portion (34). If the patient dies, the wing portions (36) are unpacked and the re-closable closure means (32) operated to close the body bag (20) to contain the corpse.
