    Abstract: 7349. Stewart, A. April 7. Feed-water, heating.-An improvement in the invention described in Specification No. 15,497, A.D. 1904, consists in the placing of a partition in the exhaust or blast pipe of the locomotive, thus causing the steam to traverse a conduit containing the feed-heating pipes before returning to the blast pipe. Fig. 1 shows a sectional elevation and Fig. 2 a view at right-angles. A partition A, placed diagonally in the blast pipe B, causes the steam to pass around the conduit E containing the feed-heating tubes F, which are secured to tube-places G in the casings H, H'. The water is thus heated by the steam and also partly by the products of combustion passing through the smoke-box C.

    Abstract: 18,952. Stewart, A. Sept. 2. Valve-chests ; receivers, intermediate ; exhaust pipes.-Feedwater is heated in surface apparatus located in the valve-chests or receivers between the cylinders of multiple-expansion engines or in the exhaust pipes. Figs. 3 and 4 show sectional views at right-angles to each other of the feed-heater within a steam receiver between the cylinders, and Fig. 6 the heater within an exhaust pipe. The feed is pumped to one compartment i of the heater, Figs. 3 and 4, and forced through the tubing J to the other compartment. In the arrangement shown in Fig. 6, the feed enters the chamber P, and reaches the chamber P after having travelled through the serpentine pipes J contained within the exhaust pipe L.

    Abstract: Disclosed herein includes a drug delivery system comprising at least one peptide and a targeting ligand for bone fracture and/or for bone healing. Some embodiments include a peptide delivery system comprising at least an acidic, basic, hydrophilic, hydrophobic or neutral peptide linked to an acidic peptide or nonpeptidic polyanion for use in targeting the aforementioned attached peptide to a bone fracture surface. In some embodiments, a conjugated peptide expresses an anabolic function that acts through PTH receptor 1, and various formats of targeting ligands guide the drug to raw hydroxyapatite. This system offsets some side effects caused by free anabolic drug, such as high blood calcium concentration
