Title: Shielded vehicle brake
Inventor: SIEGRIST ERIC
IPC: F16D53/00
Filed: 1993-03-17
Abstract: The present invention relates to a vehicle brake and hub (2) comprising a ring braking member (4) having cylindrical brak-ing surfaces (6, 8) both to the interior and exterior of the member in combination with a hub (14). The hub includes fan blades (22) which cause, during rotation of the hub (14), an axial flow of air to move through and to extract heat from the fan blades (22). A shield (50) is provided immediately adjacent and spaced from the interior braking surface (6) to separate the braking sur-face from the air flow. Heat energy is transferred principally by radiation to the shield (50) from braking surface (6), which heat energy is subsequently transferred to the air flow. The shield (50) protects the braking surface (6) from dirt, water or other con-taminates which could reduce the effectiveness of the interior braking surface (6).

Title: Ifn receptors recognition factors, protein sequences and methods of use thereof
Inventor: DARNELL JAMES E JR
IPC: C07K16/00
Filed: 1993-03-19
Abstract: Receptor recognition factors exist that recognize the specific cell receptor to which a specific ligand has been bound, and that may thereby signal and/or initiate the binding of the transcription factor to the DNA site. The receptor recognition factor is in one instance, a part of a transcription factor, and also may interact with other transcription factors to cause them to activate and travel to the nucleus for DNA binding. The receptor recognition factor appears to be second-messenger-independent in its activity, as overt perturbations in second messenger concentrations are of no effect. The concept of the invention is illustrated by the results of studies conducted with interferon (IFN)-stimulated gene transcription, and particularly, the activation caused by both IFN.alpha. and IFN.gamma.. Specific DNA sequences have been prepared that correspond to polypeptide fragments of two of the ISGF-3 genes, and antibodies have also been prepared and tested. The polypeptides confirm direct involvement of tyrosine kinase in intracellular message transmission. Numerous diagnostic and therapeutic materials and utilities are also disclosed.

Abstract: A method for cascading or linking seismic vibrator sweeps to form a cascaded sweep sequence. According to the method, a first cascaded sweep sequence is generated containing N sweep segments linked end-to-end. The N sweep segments are substantially identical, except that the initial phase angle of each sweep segment within the sweep sequence is progressively rotated by a constant phase increment of about 360/N degrees. A second cascaded sweep sequence is generated consisting of (i) N consecutive sweep segments linked end-to-end which correspond to said first cascaded sweep sequence and (ii) an additional sweep segment linked to the N consecutive sweep segments which is positioned and phased so as to substantially suppress harmonic ghosts during correlation. One of these cascaded sweep sequences is used for the vibrator sweep sequence and the other is used for the correlation reference sequence. Any type of sweeps may be cascaded or linked according to the method, and any amount of padding (listen time) may be inserted between the individual sweep segments.

Title: Method of processing fresh meat
Inventor: VERHAAG HUBERT
IPC: A23L13/70
Filed: 1994-10-24
Abstract: Described is a method for the processing of raw meat, in particular the curing and preservation of fresh beef, pork, veal, lamb, game, poultry, fish, sausage and ham. The method calls for the meat to be stored for a pre-determined length of time in a hermetically sealable space (1) in an atmosphere which is different from the ambient atmosphere. This atmosphere is established by first extracting from the hermetically sealable space the gases corresponding to the ambient atmosphere through an extraction port (13) and then introducing oxygen through an inlet port (4) to give an oxygen atmosphere at a pressure above atmospheric pressure. Throughout the whole of the remaining storage time, the pressure in the hermetically sealable space is kept above atmospheric pressure. This improves the tenderness of the meat, as well as its keeping qualitites, and ensures long-lasting freshness. Also described is a device for carrying out the method.
Patent CA-2154518-A1 (CA)
Inventor: NAKAMACHI ICHIRO
IPC: F23D14/66
Filed: 1995-07-27
Abstract: The present invention relates to a low nitrogen oxygen regenerative burner, a regenerative burner system and a regenerative burning method. The low nitrogen oxide regenerative burner is comprised of one or more pairs of regenerators having a regenerating section inside and air supply and exhaust ports which open directly into a furnace; and one or more fuel injection nozzles for each of the air supply and exhaust ports, which also open directly into the furnace at locations apart from the corresponding air supply and exhaust port. The regenerative burner system consists of a furnace body, the low nitrogen oxide regenerative burner and a control means. The regenerative burning method is the process whereby air is preheated in the regenerator, injected from the air supply and exhaust ports of the regenerators into the furnace, fuel from the fuel injection nozzles located apart from the air supply and exhaust ports, is injected. The air and fuel form respectively independent jets, and suck large amounts of the inert gas filling the furnace as the combustion product, to be mixed with it, before they are mixed with each other to initiate burning. After the air and fuel have been sufficiently diluted by the inert gas, they are mixed with each other for burning. Slow burning occurs at a low oxygen concentration, and the existence of a large amount of the inert gas can keep the flame temperature low, all of which effectively inibit the formation of thermal NOx.

Filed: 1994-02-22
Abstract: This invention relates to halide glasses which have particular utility as hosts for rare earth elements in order to provide optical amplification by laser activity. The glasses are characterized in that the metal content is similar to conventional ZBLAN glasses except that it has been discovered that the replacement of Al by Y and In and the use of more than one alkali metal fluoride, e.g. NaF, CsF and LiF, has synergistic benefits. The Synergistic benefits are good lasing performance (due to the low content of aluminium) and good stability in spite of the low content of aluminium. Pr3+ constitutes a good lasing species for amplifying telecommunication signals at 1300 nm using pump radiation at 1020 nm.
