摘要:
A novel oxidizing system comprising ascorbic acid, at least one metal ion and an oxidizing agent capable of generating an oxidizing potential of from about 100 to about 500 millivolts at a pH ranging from about 2 to about 10. The oxidizing system can be used in quenching or neutralizing permanent wave processes and in developing oxidative hair color.

The invention relates to a set for inserting a shunt valve into a surgically produced connecting channel between the trachea and the oesophagus of a laryngectomee. The shunt valve has at least two flexible, rolled up fixing strips at the oesophagus end. The fixing straps can be unrolled after introduction into the connecting channel and then rest against the oesophagus wall. The set has a support with a proximal, essentially cylindrical coupling piece on which the shunt valve is placed, and a holding and releasing element, which releasably holds the at least two fixing straps in their rolled-up position and releases them when activated.
摘要:
In an integrated optoelectronic microelectronic system, an optoelectronically active diode part is formed in a semiconductor substrate by zones forming depletion layers. The system is provided in a mesa that stands vertically on a semiconductor substrate and runs in a direction of extension thereof. A light waveguide is optically coupled to the diode part in such a way that light is coupled into the diode part via the mesa side wall.
摘要:
In some embodiments, an inter-partition apparatus includes a set of registers to store direct memory access (DMA) controls and to store an access control list visible to two or more operating environments separated by a partition, the set of registers including posted receive buffers and transmit pending buffers. A DMA device streams data in both directions between the two or more operating environments in response to the stored DMA controls and in response to the access control list using the posted receive buffers and the transmit pending buffers. Other embodiments are described and claimed.
摘要:
Apparatus, systems, methods, and articles may operate to store one or more parameters associated with a pseudo-device in a device configuration table associated with a first partition within a multi-partition computing platform. An inter-partition bridge (IPB) may be exposed to an operating system executing within the first partition. The IPB may be adapted to couple the first partition to a second partition sequestered from the first partition. The IPB may be configured by the parameter(s) associated with the pseudo-device. Other embodiments may be described and claimed.
摘要:
In order to prevent sparking or corona effects in the high voltage carrying parts of the outdoor high voltage circuit breaker, shielding electrodes are provided. The shielding electrodes are angular frames. The frames are formed of hollow cylindrical straight rods and of substantially spherical corner pieces which connect the rods with each other. With this design, there are minimum costs of the component parts for shielding electrodes of varying size and shape.
摘要:
Nail polish compositions comprising a water or alcohol soluble polyamide are described. The water or alcohol soluble polyamides are prepared from the reaction of adipic acid and certain ether diamines having a molecular weight of 148 to 396. The nail polish compositions can be either non-aqueous or aqueous, and can be in the form of color enamels, nail varnishes, nail lacquers, clear base coats, topcoats, and nail hardeners.
摘要:
A pressure or draw bar of fiber-reinforced insulating material, in particular for a high voltage circuit breaker. The pressure or draw bars of fiber-reinforced insulating material are provided with connecting elements for the introduction of force for operating the circuit breaker. The connecting apertures of the draw bar which allow connection to the circuit breaker should be simple to adjust and secure, but should be fixable in a manner which permits ready detachment. The connecting apertures of the connecting elements are arranged in a fork part, to which a slit pipe part with external threads lies adjacent. In the slit pipe part a spreading body is arranged held by a screw, which in the region of the fork part has a surface accessible for generating a rotational motion. The spreading body can thus by spreading apart the slit pipe part determine the height of the connecting apertures with respect to the bar. The fitting body is surrounded on the outside by a ring as screening.
摘要:
Stable NCO prepolymers are produced from polyisocyanates having a melting point greater than 70° C., preferably, naphthalene diisocyanate, having advantageous physical properties. An important feature of the process of the present invention is the rapid cooling of the prepolymer. The process of the present invention may be carried out on a continuous or batch basis. The prepolymers of the present invention are particularly suitable for the production of cast polyurethane elastomers.
摘要:
The present invention relates to steroid hormone products, such as oral contraceptive products, including at least one steroid active ingredient mixed with an excipient and having improved dissolution and release rate properties. The invention further relates to methods for making such steroid hormone products, wherein a mixture of the hormone and the excipient is subjected to sufficient mechanical energy to form a powder blend wherein the hormone is stabilized by the excipient in substantially non-crystalline form.
