Abstract: A wound covering material containing at least macromolecules having a sol-gel transition point in an aqueous solution; substantially displaying a water-insolubility at a temperature higher than the sol-gel transition point; and reversibly displaying a water-solubility at a temperature lower than the sol-gel transition point. Since this wound covering material can be kept in the state of a solution on the surface of a wound, it can be stuck fast to the surface of a wound of a complicated shape.      In addition, this wound covering material provides a wound covering product capable of gelling speedily at the temperature of a wound and being stuck fast to the surface of a wound stably. This wound covering product is stable without being dissolved by exudate flowing from the surface of a wound, and promotes a healing process as it prevents the secretion of exudate from the surface of a wound until the wound has been healed.

Abstract: A support arm has stationary support structure, a boom, a knuckle and an auxiliary jib section. The boom connects at one end to the support structure and at an opposite end to one end of the knuckle, and an opposite end of the knuckle connects to one end of the auxiliary jib section. Each connection is a pivotal connection for pivoting about vertical pivot axes. An opposite end of the auxiliary jib section connects to a main jib section through a pivotal connection for pivoting about a horizontal axis. First and second flexible tubes connect across the knuckle and the auxiliary jib section between the boom and the main jib section. The flexible tubes extend from points on the main jib section in parallel horizontally spaced relationship and pass slippingly and in parallel longitudinally through parallel horizontally spaced guide sleeves that are connected on the auxiliary jib section. In the region of the knuckle the flexible tubes converge and cross over one another in a loosely curved configuration toward horizontally spaced points on the opposite end of the boom. A drive adjusts the elevation of the main jib section by pivoting it about the horizontal pivot axis, between an upper position parallel to the boom and a lower position inclined downwardly thereto. This arrangement allows vertical rise and fall of the main jib section and pivoting of the jib horizontally relative to the boom.

Inventor: ROGGATZ MAX
IPC: C23C8/30
Filed: 1996-04-17
Granted: 2009-06-23
Abstract: The invention concerns a process and a device for controlling the CO content of a furnace atmosphere for carburizing and carbonitriding metal workpieces in a furnace, whereby the furnace atmosphere is produced by direct feeding of a mixture consisting of an oxidizing agent and a hydrocarbonaceous fuel as well as perhaps ammonia into the furnace. To ensure a continuous and trouble-free operation of the installation without sooting of the furnace, it is proposed that the CO  content of the furnace atmosphere be ascertained and that a CO  forming substance is added when a freely adjustable minimum CO  content of the furnace atmosphere is attained. The device for carrying out this process has a CO analyzer 1 for ascertaining the CO content in the furnace atmosphere and a programmable CO  control 3 for actuating a valve 4 and, if applicable, a pump 5 in dependency on the CO content in the furnace atmosphere.

Abstract: A lacrosse head having an open frame with sidewalls that curve continuously from the base to the lip of the frame so as to define a curved scoop-like frame geometry when viewed in side elevation. The frame base has an angulated ball rest surface and a shoulder recessed therefrom at which a net is attached to the base. The lip that interconnects the frame sidewalls remote from the base has an outside surface angle that cooperates with the scoop-like geometry of the sidewalls to enhance control of ground balls. The overall scoop-like construction of the head frame provides improved feel during play, and enhanced ball control and pass/shot velocity. The recessed base shoulder, particularly when combined with the angulated ball-rest surface, protects the net attachment knots from abrasion, and also improves ball control during one-handed vertical cradling.

Filed: 1996-04-04
Granted: 2002-06-04
Abstract: This invention is directed to an album flavored flour as well as to a method  of making a flavored flour dough product. The allium flavored flour comprises flour and allium oil capsules formed by protein coacervation. The allium oil capsules are heat-stable and fracturable, and are added in an amount sufficient for flavoring when the flour is formed  into a dough. Because the album oil capsules are heat-stable, the album oil does not affect the rheology of the dough during dough processing, baking or cooking. Furthermore, because the capsules are fracturable on chewing, the dough product provides a uniform and sustained allium flavor when eaten. In another aspect of the invention, the flavored flour or dough product further includes free allium material in  an amount sufficient to reduce the mix time required to develop the dough. The free allium material may be combined with the oil capsules in  a customized blend to provide the desired level of flavor and affect on dough rheology.
