Title: Digital loop carrier system
Inventor: GORSHE STEVEN S
IPC: H04Q3/42
Filed: 1993-10-25
Granted: 1999-02-16
Abstract: A telecommunication network which includes a SONET-based digital subscriber loop carrier system that supports wideband and narrowband services.  The digital subscriber loop carrier system includes a digital subscriber loop carrier system having a common module for performing common functions of the system and for transferring subscriber data between the system and a central office or local digital switch, and at least one service definition module, which is coupled to subscribers, for interfacing the subscribers to the system.  The common module and the service definition modules are coupled by a common backplane including pulse coded modulation buses and all data, including both subscriber data and control data, are transferred per the SONET protocol.  Each of the common module and service definition modules employ buses, which are also based on the SONET protocol.

Title: Propulsive thrust ring system
Inventor: LEMONT HAROLD E
IPC: B64C11/00
Filed: 1992-05-28
Granted: 2003-09-02
Abstract: A low-aspect ratio propeller system is provided with a multiple ring structure (42) formed with a plurality of circular or non-circular; annular, narrrow equivalent air foil rings (56.1, 56.2, 56.3; 56.4) which are held by rails (44) in a predetermined relationship with the propeller blades (44). The upstream ping (56.1) is located downstream from the tip vortex of the propeller (44) within the axial span of the propeller. One or more additional downstream-located rings (56.2, 56.3, 56.4) are used so as to provide at least one annular multiple ring-defined pump aperture (60, 62; 64) through or which peripheral vortices generated by the propeller blades (44) or fan blades may enhance the mass flow. These vortices increase thrust beacause their induction action on the rings, (56.1, 56.2, 56.3, 56.4) increase beneficial ring flow circulation. Augmented ring flow reduces the velocities in the expanding wake by increasing the mass flow. The destruction of tip and root vortices reduces noise. The multiple ring structure (42) also serves as a guard.

Abstract: The child safety seat for an automobile comprises a seat body forming a backrest which is arcuately movable with respect to a base.  A relative movement guiding mechanism, which is formed by combining an arcuately extending guide rail and a guide member moving along the guide rail, allows for movement of the seat body with respect to the base.  A seat is rotatably mounted on the seat body and a coupling member engages a linear portion of the guide rail, thereby maintaining the seat in a substantially constant inclination regardless of movement of the seat body.  Thus, the seat can remain in a substantially horizontal state when the angle of the backrest is adjusted, while the backrest may recline without interfering with the backrest of an original seat in the automobile upon which the child safety seat is mounted.  Thus, the child is not forced into an uncomfortable position when the backrest of the child safety seat is reclined.

Abstract: Disclosed are abrasive wiping articles, e.g., nonwoven, preferably paper towels, which comprise an absorbant nonwoven substrate having printed thereon a cured scrubbing bead mixture which comprises a) certain carboxylated, ionically-charged polymeric abrasive particles, b) a carboxyl group-containing polymeric adhesive material, and c) an amino-epichlorohydrin, e.g., Kymene ~ cross-linking agent. The polymeric abrasive particles range in size from about 20 to 400 microns and have a knoop hardness of from about 4 to 25.  The polymeric adhesive material, upon curing, has a Knoop hardness of from about 0.5 to 17.  Preferred wiping articles of the foregoing type have a pattern of the scrubbing bead mixture printed onto from about 20 % to 70 % of the surface area of a paper substrate with the abrasive particles affixed to the substrate in such a manner that their exposed portion extends for a distance of from about 40 to 300 microns above the surface of the paper substrate.  Wiping articles of this type are especially useful for removing soil and stain from hard surfaces with the polymeric scrubbing particles thereon being especially resistant to removal during use.  Also disclosed is a process for preparing abrasive wiping articles as hereinbefore described.  Such a process involves printing a pattern of the scrubbing bead mixture onto the paper substrate, drying the printed substrate and then curing the solid components of the scrubbing bead mixture to affix the abrasive scrubbing particles to the substrate.  Curing of the particular scrubbing bead mixture employed can take place at room temperature.

Abstract: The optical circulator according to the present invention comprises two birefringent crystal end-plates, non-reciprocal Faraday rotators inserted between birefringent crystal plates, and a pair of matched birefringent crystal plates disposed between the rotators. The first birefringent crystal end-plate functions as a dividing and combining means for dividing a beam into two beams of orthogonal electric filed vectors from different paths into one on the same path. The pair of matched birefringent crystal plates serve as beam path determining means shifting a beam to a different direction depending on the direction of the electric filed vector and the propagation. The pair of crystal plates are substantially identical but oppositely oriented, such that the pair of means have opposite beam shifted directions.

Granted: 2005-01-25
Abstract: A device for prevention of involuntary urination in a female comprises an elastic body (21) designed for arrangement in the vagina for compressive action on and support of the neck of the bladder. The body (21) is made of a compressible material and comprises at least two projecting legs (23) joined in a flexible base (22) and is dimensioned in such a way that in the non-deformed state of the body the longest distance between the free ends of at least two legs exceeds the distance between the anterior wall and the posterior wall of the vagina. After the insertion of the body into the vagina in an elastically deformed state with the legs tint in a direction towards each other, an active pressure is thus exerted on the bladder neck. On their mutually facing sides, the legs are designed in such a way that in said elastically deformed insertion state they come into mutual contact for the provision of an increased elastic force of restitution. An applicator for insertion of the device comprises an elongated member having a proximal end and a substantially rod-shaped distal end portion for abutment with a bevel or a recess (24) formed in the angle between the legs of the device.

Abstract: A unit for the treatment of water by ozonization characterised in that it includes, on the one hand at least one installation for the production of ozonized white water and, on the other hand, at least one contactor in a way that the mixing of the water to be treated and the white water occurs in said contactor. The installation for the production of ozonized white water includes means for dissolution of ozone under pressure in a carrier liquid. In a first embodiment , allowing the treatment of high flows, a portion (typically 5 to 15%) of the main flow of the fluid to be treated is diverted to the vessel for the production of ozonized white water according to the invention, then reintroduced into the main flow within a contactor allowing the whole flow to be treated. In a second embodiment, corresponding more to the treatment of comparatively lower flows, the total flow of fluid is treated directly in the vessel for the production of ozonized white water.
