The invention comtemplates controlled ablation of the cornea, using ultraviolet laser radiation, wherein irradiated flux density and exposure time are so controlled as to achieve desired depth of the ablation. Sculpturing action results from controlled change of projected laser-spot size, in the course of a given treatment, wherein, in one illustrative case, projected laser-spot size ranges from a...

The invention contemplates use of a scanning laser characterized by ultraviolet radiation to achieve controlled ablative photodecomposition of one or more selected regions of a cornea. Irradiated flux density and exposure time are so controlled as to achieve desired depth of the ablation, which is a local sculpturing step, and the scanning action is coordinated to achieve desired ultimate surface ...

. An electrical lighting system consists of two or more, adjacently mounted, lighting modules where each module consists of an elongated, box-type housing adapted to be mounted in a predetermined arrangement on a light source supporting surface, the housing being provided with mounting and electrical supply means for a light source and, further, with longitudinal guide means mounted on the sides o...

Silicone rubbers can not normally be vulcanized or cured with sulfur. For this reason it has been traditionally difficult to co-cure blends of silicone rubbers and diene rubbers utilizing conventional sulfur curatives. This problem has severely limited the utilization of silicone rubber/diene rubber blends in many applications. However, this difficulty can be easily overcome by utilizing in such b...

A laser light beam generating apparatus includes a laser diode, a laser medium, a non-linear optical crystal element, reflecting mirrors, a deflecting mirror, a temperature-control device and a case. The laser diode emits at least one pumping laser light beam. The laser medium is excited by the pumping laser light beam from the laser diode. The non-linear optical crystal element is arranged in out...

Deflection circuit for a television receiver using symmetrical deflection. For the symmetrical deflection, it is necessary to generate a step shaped deflection field for the vertical deflection because the lines described from the left to the right edge of the picture and from the right to the left edge of the picture would otherwise diverge. A step shaped vertical deflection field of such type ha...

The machine, like those already in use, permits olives and fruit with hard shells to be collected from the ground by using the suction effect of a current of air; compared with those however, it simplifies the system of cleaning which is performed wholly during the collection stage, without the need for further operations, by making use of the oval shape of the collected fruit, the effect of gravi...

A method of manufacturing a fiber glass blanket encapsulated within an air-permeable sheet on one major face and a non-porous film extending over the other major face and the two side edges. The film is applied by being wrapped around the edges of the backed blanket and preferably being heat sealed to the backing sheet. The air-permeable sheet is preferably applied to the blanket before curing of ...

A torsion damper device comprises two coaxial parts, a circumferentially acting resilient element, and a friction device which acts in an axial sense between the two coaxial parts. The friction device includes a friction ring which is in contact with a first friction surface. The friction device is a unitary assembly which comprises at least one element of elastic material. The friction ring is se...

The invention relates to mixtures of dichlorotoluenes (DCT), trichlorotoluenes (TCT) and trichlorobenzenes (TCB) which do not have a fire point and a pour-point of less than -10@C. For example, the mixture of 15% DCT, 40% TCT and 45% 1,2,4-TCB has a pour-point of -35@C and an oxygen number (oxygen index) greater than 65. These liquids can be used as dielectrics.
