Title: Overload condition indicating fuse
Inventor: KRUEGER DAVID J
IPC: H01H85/30
Filed: 1990-09-26
Granted: 1996-11-05
Abstract: A fuse (2) is provided which has a fuse housing with a transparent portion thereof, and a fuse element (4) extending through the housing (6) which is coated with a preferably non-hazardous temperature-responsive material (5). The temperature conditions generated at the interface between the coating (5) and the fuse element (4) cause the coating to leave the fuse element and deposit upon this transparent portion of the housing (6). The temperature-responsive coating (5) on the fuse element (4) will be transferred to the housing walls even where modest current overloads flow which do not immediately open the fuse. Different circuit overload conditions, including short circuit events, produce different visual indications or colorations on the transparent housings inside surfaces, which serves to identify the nature and degree of the overload problem existing in the circuit. Coatings, also capable of fluorescing under specific irradiation conditions, may be used.

Title: Interface arrangement for a filter bag in a vacuum cleaner
Inventor: GUEHNE WIELAND
IPC: A47L9/14
Filed: 1992-08-03
Granted: 1994-11-01
Abstract: The invention relates to an electric vacuum cleaner having a filter bag intermediate carrier disposed between a filter cassette arranged above a motor-driven blower and the motor housing.  The intermediate carrier is pivotally mounted via a hinge and has guide cams which dip into engaging recesses of a base plate of the filter bag.  The vacuum cleaner apparatus can only be operated with filter bags which are specific to this apparatus.  Safety cams are formed on the intermediate carrier and follow the inner wall surface of the filter cassette when the intermediate carrier is closed.          Catches are formed on the inner wall surface but do not catch the safety cams if an authorized filter bag is placed in the filter cassette.  However, if an unauthorized filter bag is placed in the filter cassette, then the structure of this filter bag causes the safety cams to deflect and catch in the catches thereby preventing the operator from completely closing the intermediate carrier on the filter cassette.

Title: Metal complexes of water soluble texaphyrins
Inventor: SESSLER JONATHAN L
IPC: C07H17/02
Filed: 1993-01-07
Granted: 2001-05-29
Abstract: The present invention involves water soluble hydroxy-substituted texaphyrins retaining lipophilicity, of formula (I) wherein: M is H, a divalent or a trivalent metal cation; R1, R2, R3, R4 and R5 are independently H, OH, C n H(2n+1)O y or OC n H(2n+1)O y where at least one of R1, R2, R3, R4 and R5 has at least one hydroxy substituent; the molecular weight of any one of R1, R2, R3, R4 or R5 is less than or equal to about 1000 daltons; n is a positive integer or zero; y is zero or a positive integer less than or equal to (2n+ 1); and N is an integer between -20 and +2. These expanded porphyrin-like macrocycles are efficient chelators of divalent and trivalent metal ions. Various metal (e.g., transition, main group, and lanthanide) complexes of the hydroxy-substituted texaphyrin derivatives of the present invention have unusual water solubility and stability. They absorb light strongly in a physiologically important region (i.e. 690-880 nm). They have enhanced relaxivity and therefore are useful in magnetic resonance imaging. They form long-lived triplet states in high yield and act as photosensitizers for the generation of singlet oxygen. Thus, they are useful for inactivation or destruction of human immunodeficiency virus (HIV-1), mononuclear or other cells infected with such virus as well as tumor cells. They are water soluble, yet they retain sufficient lipophilicity so as to have greater affinity for lipid rich areas such as atheroma and tumors. They may be used for magnetic resonance imaging followed by photodynamic tumor therapy in the treatment of atheroma and tumors. These properties, coupled with their high chemical stability and appreciable solubility in water, add to their usefulness.

Abstract: A slack adjusting brake cylinder for use in a fluid brake unit of a railway transit vehicle having a brake piston slidably mounted on a support rod within a brake cylinder receiving cavity of the brake unit.   A plurality of friction/load rings are slidably mounted on the support rod, a first side of which serves as an abutment stop to limit the extent of return of the brake piston along the support rod.  The friction/load rings are tightly engaged on the support rod so that they are slidable only in response to fluid brake pressure forces.  A spring loaded compression member is engaged with a second side of the friction/load rings, and is partially compressed between the brake piston and the friction/load rings when the brake piston is advanced outwardly on the support rod in response to activation of the brake unit, and functions to return the brake piston into engagement with the friction/load rings  when  the  brake  unit  is deactivated.    The  degree  of compression of the spring loaded compression member is limited so that when the compression has reached the limit, the spring loaded compression member will push the friction/load rings to a new position on the support rod.

Title: Ultra-wide field of view, broad spectral band helmet visor display optical system
Inventor: CHEN CHUNGTE W
IPC: G02B27/00
Filed: 1994-09-29
Granted: 2000-03-14
Abstract: An optical display system in which an image is projected onto a combiner surface (4) at a significant bending angle .theta. effectively compensates asymmetric aberrations, including quadratic, linear and constant binodal astigmatism components and both linear and constant coma components. Forward and rear optical lens relay groups (14, 16) are positioned between an image generator (6, 8) and the combiner surface. The two relay groups are independently decentered and angularly tilted to increase the degrees of freedom available for aberration compensation. The lenses (24, 26, 28, 30, 32, 34, 36, 38, 40) included in the two relay groups are also designed to compensate for chromatic aberrations, thus allowing for the use of a broad bandwidth combiner and an operating bandwidth that encompasses substantially the full visible spectrum. The reduction in aberrations makes possible a significant increase in the system's field of view.
