摘要:
A tube heat exchanger intended to be used for the production of carbon black, includes a cylindrical closed chamber having a plurality of tubes which extend through the entire, essentially cylindrically shaped chamber. Upper end of the tubes are attached to an upper end wall, preferably by welding, and hang down to a tube plate. The tube plate equipped with compensating devices to enable thermally induced expansions and contractions of the tubes to occur.

In accordance with this invention, an RPE cell membrane associated protein which has a molecular weight of about 32 kd, as determined by SDS-PAGE, has been discovered. This protein, referred to an "p32," forms an oligomeric protein complex with the previously characterized p63 protein, a component of the membrane receptor for RBP. A nucleic acid molecule which codes for the p32 protein has also been isolated and sequence analysis shows that the p32 protein belongs to the family of short chain alcohol dehydrogenases, and exhibits 11-cis retinol dehydrogenase activity, the enzyme which catalyzes conversion of 11-cis-retinol into 11-cis retinaldehyde.
摘要:
Carbon black is produced by burning a mixture of air and oil to produce hot gases and then conducting the hot gases through tubes extending through a chamber of a heat exchanger. Heat exchange air is conducted through the chamber in a direction opposite the direction of gas flow, in heat-exchange relationship with the tubes, to pre-heat the air. The pre-heated air is then mixed with the oil to be burned. Prior to entering the chamber, the air is conducted within a hollow section of the wall structure of the heat exchanger to transfer heat from a hot end of the wall structure toward a cooler end thereof.
摘要:
Isolated receptors for lipocalins and retinol binding proteins are disclosed, as are nucleic acid sequences coding for these molecules, and antibodies which bind to these receptors. Various uses of these materials are described as well.
摘要:
VEGF-B polypeptides from the PDGF family of growth factors having the property of promoting mitosis and proliferation of vascular endothelial cells, DNA sequences encoding these polypeptides, pharmaceutical compositions containing them and antibodies which react with them. The VEGF-B polypeptides are useful in stimulating angiogenesis as well as in diagnostic applications.
摘要:
Methods and compositions for modulating blood-neural barrier (BNB) for the treatment of CNS conditions such as edema, and for increased drug delivery efficacy across the BNB. The present invention further relates to improved tPA treatment of ischemic cerebrovascular and related diseases in combination with antagonism of the PDGF signaling pathway. The inventive method and composition is particularly suitable for conjunctive therapy of ischemic stroke using tPA and an anti-PDGF-C antagonist or an anti-PDGFR-α antagonist.
摘要:
A steering wheel arrangement for a motor vehicle includes a steering column having a first end for cooperation with a steering wheel and a second end for cooperation with a vehicle steering mechanism. The steering wheel arrangement further includes a suspension arrangement for the steering column. The suspension arrangement includes two pivot joints and is pivotally connected to the steering column via a third pivot joint, the first, second and third pivot joints including first, second and third locking arrangements, respectively. The steering wheel arrangement has thus three adjustable pivot points where only one or two of the three pivot joints are adjustable in a first step depressing a foot pedal to a first position and only the remaining of the three pivot joints are adjustable in a second step depressing the foot pedal to a second position which implies that the adjustments can be made in a secure way by the driver during the ride.

The present invention relates to a method of using a cleaning device for cleaning outlet ports (11) or the like and/or outlet spouts (12) or the like in soda recovery boilers (13) or the like, the cleaning device comprising at least one connecting rod (9). The cleaning device has at least one front tool part (1a-d, 3, 6), mounted on said connecting rod (9).
摘要:
The present invention provides materials and methods for modulating FATP expression and/or activity in vivo. The materials and methods have numerous diagnostic, prophylactic, and therapeutic applications for various diseases and conditions that are influenced by FATPs, or characterized by excessive or inadequate FATP expression or activity.
摘要:
A method of modulating, regulating and/or stabilizing angiogenesis in a mammal in need thereof, in which the PDGF-D level or activity or both in the mammal are modulated or increased. In preferred embodiments, an active PDGF-D polypeptide, or a polynucleotide encoding an active PDGF-D is administered to the mammal, preferably at a location where angiogenesis modulation or stabilization is desired. The PDGF-D is advantageously co-administered with an angiogenic growth factor, such as a member of the VEGF family of growth factors, in particular VEGF-E. The claimed method inhibits leakage of blood vessels and is useful, inter alia, for treatment of edemas.
