Title: New oral formulations for tetrapyrrole derivatives
Inventor: GRAEFE SUSANNA
IPC: A61P35/00
Filed: 2010-04-28
Abstract: Oral formulations and method of formulating photosensitive agents for oral administration during photodynamic therapy (PDT) and Antimicrobial photodynamic therapy (APDT) treatment are presented. The oral formulated photosensitizers show increased solubility and permeability, thus improving the bioavailability of photosensitizers at the treatment site. An orally administered photosensitizer is suitably formulated for mucosal adhesion and absorption via gastrointestinal mucosal membranes. Oral formulation provided herein use lipids and known proteins as carriers for photosensitizers by oral route. Carriers for encapsulating preselected photosensitizers include conventional liposomes, pegylated liposomes, nanoemulsions, nanocrystrals, nanoparticles, fatty emulsions, lipidic formulations, hydrosols, SMEDDS, Alpha-Feto protein (AFP), and Bovine-Serum-Albumin (BSA), fatty emulsions, hot-melt-extrudates and nanoparticles. The oral formulation, in case of a hydrophobic photosensitizer in the present invention, is stabilized using suitable surfactants/solubilizers thus preventing aggregation of the drug in the stomach and until it is absorbed in the duodenum and the small intestine. Oral formulations can be administered in the form of liquid, capsule, tablet, powder, paste or gel. Formulated drugs can be administered orally as one single dose or in multiple doses before administering PDT. In one embodiment Temoporfin (m-THPC) is used as a photosensitizer in the oral formulations. Temoporfin like many hydrophobic photosensitizers are especially suitable to be administered orally because there is no known enzyme system in the mammalian body which can metabolize Temoporfin or similar photosensitizers. Temoporfin can reach the blood system unchanged and fully active after absorption of the formulation in the gastrointestinal tract.

Title: Improved process for renewing cylinder heads
IPC: F02F1/24
Filed: 1988-12-30
Abstract: A process for renewing a cylinder head, preferably a cast aluminum water cooled cylinder head (30) from a used condition to a rebuilt condition suitable for reuse. In a qualifying stage the used cylinder head is stripped of removable parts, inspected, heat treated for cleaning and stress relieving purposes, and then pressure tested to detect leaks through cracks (45, 46) or excessive porosity (48). If cracks are located, the cylinder head passes through a reconstruction stage wherein cracked areas are removed and replaced by welded material (45b), recontoured and preferably again pressure tested. A cylinder head which did not need reconstruction (or after reconstruction) then passes to the rebuilding stage where it is essentially machined and component parts replaced. Included in the rebuilding stage is a line-boring and surface gasket facing procedure for eliminating the adverse effects of warpage and a vacuum impregnation step to seal the pores of the cylinder head.
Patent EP-0433400-A4 (EP)
Title: Light-energized electronics energy management system
IPC: G06F3/048
Filed: 1989-10-04
Abstract: An irrigation controller is powered for all normal operations by light incident upon an 18 square inch photovoltaic module. Electrical power from the photovoltaic module is stored in high performance "super" capacitors. A transportable battery power source is connected to the controller to power its communication, such as for manual exercise and/or the loading of irrigation control programs. The external battery power source leaves the capacitor power storage recharged at the conclusion of each communication episode. The irrigation controller electronics, save for a real time clock that is updated, are not provided with a timing signal, and thereby consume almost no energy, save for brief millisecond sporadic time intervals of scheduled irrigation control. Capacitor power storage is approximately 6.5 mWH. Worse case photovoltaic energy production is 7.6 mWH daily. The sporadically operative irrigation controller uses less than 6.4 mWH per day, with remaining energy expended on up to 128 ultra-low-power valve actuations per day.

Filed: 1991-12-18
Abstract: A spectrograph usable as a demutiplexer/detector in a wavelength division multiplexing optical system. The spectrograph comprises a planar waveguide (50) and a detector array (52). The planar waveguide (50) has a dispersive edge (56) having an inwardly concave shape, an input edge (62), and a straight output edge (64). The dispersive edge (56) has a reflective diffraction grating (60) formed on it, the grating (60) having a variable line spacing. An optical input signal comprising a plurality of different wavelength ranges enters the waveguide at the input edge (62), and travels through the waveguide and strikes the grating (60). The grating (60) focuses the optical energy in each of the wavelength ranges at a focal spot at the output edge (64), the position of each focal spot being a function of wavelength. The detector array (52) comprises a plurality of photodetectors positioned along a straight line, such that the photodetectors are positioned at the focal spots. Each photodetector therefore detects the optical energy in one of the input ranges. A stack of such planar waveguides may be assembled to form a multi-channel spectrograph.
