A respirator assembly has a respirator mask and a separate bracing device. The bracing device has a pressure element mountable over a frontpiece of the respirator mask, which bears against that frontpiece to hold the respirator mask against the face of a user. The bracing device also has two connection portions, each having one end attached to the pressure element and the other end being for attaching the bracing device to a helmet worn by the user. The connection portions are extendable. Thus, shortening or distending the connection portions reduces the distance between the helmet and the respirator mask and thereby causes the pressure element to bear against the frontpiece of the respirator mask, compressing the user's head between the helmet and the mask and thereby holding the mask against the user's face.

The invention relates to the use of gelatin-like proteins, or polypeptides, with an increased calculated glass transition temperature as stabilisers in lyophilized biological or pharmaceutical compositions.

A horseshoe includes a thin, resilient member, embedded in a moldable material such as plastic or composite. Due to this dual construction, the horseshoe is strong yet light in weight. The moldable material has a thickness which varies across the horseshoe, so as to define a cavity in the space between the shoe and the horse's hoof. A channel, formed in the moldable material, provides access to the cavity, which can be filled with a medicated material after the shoe has been attached to the hoof. In an alternative embodiment, a source of current can be connected across the ends of the resilient member, causing the resilient member to function as a resistance heater, which can melt an adhesive used to attach the shoe to the hoof. The latter alternative can also be practiced with conventional all-metal horseshoes, or with an insulating horseshoe that is provided with an external conductive element.
