Title: Aspheric toric lens designs
Inventor: ROFFMAN JEFFREY H
IPC: G02B13/00
Filed: 1996-05-02
Abstract: Aspheric toric lens designs are disclosed which reduce the number of cylindrical axis locations required for stock keeping units in inventory by aspherizing the toric surface thereof. The present invention pertains to ophthalmic lenses, and in particular to contact lenses such as soft hydrogel contact lenses, particularly designed to fit astigmatic patients who are either non-presbyopic or presbyopic. One of the front and back surfaces of the aspheric toric lens defines a spherical surface corresponding at least to the patient's basic distance prescription Rx. The other of the front and back surfaces defines an aspheric toric curve, wherein the toric surface is constructed with aspheric radii, such that the aspheric curve desensitizes axial misalignment of the toric curve by providing an enhanced depth-of-focus. When the aspheric toric surface is on the back surface of the lens, the spherical curve on the front surface of the lens can comprise a single spherical curve corresponding to the patient's basic distance prescription Rx. When the aspheric toric curve is on the front surface of the lens, the spherical curve on the back surface of the lens can comprise a multifocus concentric annular ring spherical surface design.

Title: Plates for dual plate check valves
Inventor: COOPER JAMES NICHOLAS
IPC: F16K15/03
Filed: 1994-11-30
Abstract: A metal plate (20) for a dual plate check valve. A central portio n (36) of a D-shaped plate (20) is reinforced such as by means of a raised area (36) on either or both sides of the plate to resist deformation when subjected to reverse pressure in the valve closed position, while the ends (35) of the plate are not reinforced.  This enables the valve plate to deform in a controlled manner to maintain or improve sealing engagement with a valve seat when the valve is subjected to reverse pressure in the valve closed position.

Title: Heavy duty electronic brake stroke indicator
Inventor: MARTENS TIMOTHY F
IPC: F16D66/02
Filed: 1994-11-29
Abstract: Electronic stroke indica-tors have sensor structures (34, 60, 80, 110) which are incor-porated into a stone shield (28, 62, 82, 116) for a brake actua-tor (20). The incorporation of the rensor (34, 66, 119) stone shield (28, 62, 116) protects the sensor (34, 60, 119) and its associated wires (50, 69 121) and cotacts from dam-age by the other components in the brake actuator (20). In particular, the spring is typi-cally maintained out of contact with any of the electric por-tions of the electronic stroke indicator, thus prolonging the life of the electronic stroke in-dicator.  In further features of this invention, a magnetic sen-sor (34) may monitor the posi-tion of magnetic portions (36) on a piston rod (32). Alterna-tively, a pair of electric con-tact switches (96, 98) may be serially contacted by a struc-ture on the piston rod (94) as the brake moves further out of stroke. The two electric contacts (96, 98) provide different signals to an operator in a vehicle cab such that signals of the level of out-of-stroke conditions are provided to the operator. In a further embodiment, a load cell (119) monitors the compression in a spring (112) in the brake housing (111) to provide an indication of an out-of-stroke condition.

Patent CA-2182960-A1 (CA)
Title: Texaphyrin metal complexes having improved functionalization
Inventor: SESSLER JONATHAN L
IPC: A61K47/48
Filed: 1995-02-15
Abstract: Texaphyrin metal complexes of formula (I) having improved function-alization include the addition of elec-tron donating groups to positions 2, 7, 12, 15, 18 and/or 21 and/or the addi-tion of electron withdrawing groups to positions 15 or 18 of the macrocycle. Electron donating groups at positions 2, 7, 12, 15, 18 and/or 21 contribute elec-trons to the aromatic .pi. system of the macrocycle which stabilizes the metal complex to demetallation and the imine bonds to hydrolysis. These texaphyrin metal complexes having enhanced sta-bility are useful for localization, mag-netic resonance imaging, radiosensiti-zation, radiation therapy, fluorescence imaging, photodynamic tumor therapy and applications requiring singlet oxy-gen production for cytotoxicity.  Elec-tron withdrawing groups at positions 15 or 18 render the macrocycle more readily reduced, i.e. the redox potential is lower and the macrocycle more readily gains an electron to form a radical.  Such texaphyrins having a low redox potential are useful for radiosensitization applications.

Title: High efficiency projection displays having thin film polarizing beam splitters
Inventor: LI LI
IPC: H04N9/31
Filed: 1996-08-13
Abstract: A projection display system includes a thin film polarizing beam splitter/combiner has first and second light transmissive substrates in the form of prisms and a plurality of thin film layers disposed between the prisms. The thin film layers and have predetermined thicknesses and refractive indices which allow unpolarized incident light to be separated into s-polarized and p-polarized light beams. Both frustrated total internal reflection and thin film interference are simultaneously employed to allow s-polarized light to be transmitted and p-polarized light to be reflected over a wide range of wavelengths and angles of incidence. The device further includes two spatial light modulators for encoding an image to be projected. By providing a different signal to each spatial light modulator, a 3 dimensional display results.

Title: Implement for personal cleansing and method of construction
Inventor: GIRARDOT RICHARD MICHAEL
IPC: A47K7/02
Filed: 1995-03-09
Abstract: An extruded scrim having a diamond-mesh pattern is used to construct a personal cleansing implement. The diamond-mesh material is produced from a hydrophobic flexible polymer. The implement comprises a piece of tubular scrim having a longitudinal axis. The tubular scrim is stretched transversely to the longitudinal axis and is gathered parallel to the longitudinal axis to form circumferential pleats. In one embodiment the stretched and gathered tubular scrim is heat set in its expanded and pleated condition. A second piece of tubular scrim is placed inside the pleated and expanded scrim tubing. One end of the second piece is inverted over the outside of the pleats and connected to the other end to envelop the pleated and expanded scrim tubing. In another embodiment the pleats are not heat set and remain resilient. This embodiment has a means for confining the circumferential pleats from axial expansion. A band of material is looped through the scrim tubing and around its outer surface. Pleats are then evenly distributed around the loop to form a toroidal shaped implement. The personal cleansing implement of the present invention has a high open area, without a dense center core to inhibit rinsing and drying.

Patent CA-2197236-A1 (CA)
Inventor: COMTE MICHEL
IPC: H04B3/14
Filed: 1996-06-12
Abstract: A device (1) for correcting the amplitude/frequency characteristic of an input signal (FI) having minimum frequency f1, centre frequency f0 and maximum frequency f2, as well as an attenuation characteristic dependent on the frequency increase between f1 and f2. The correcting device (1) provides a corrected output signal (FI). Said correcting device comprises two cascaded filters (41, 42) of which the first receives the input signal (FI) and outputs a filtered signal (SFI) to the second filter, while the second filter provides the corrected output signal (FI). One of said filters is a band rejector filter (41) having centre frequency f3, where f3 is no higher than f1, and the other filter is a band-pass filter (42) having centre frequency f4, where f4 is no lower than f2. Centre frequencies f3 and f4 have the following relationship: f3 x f4 = f0<2>. The filters (41, 42) are of the same order and their overvoltage coefficients are adjusted by a control signal (SC) from a control device (43). The correcting device is particularly suitable for signals from communication cables (40).
