Abstract: Method of inserting an intraocular lens, having an optic and haptics of flexible material, through an incision into an eye, including preliminarily compressing the lens into a generally cylindrical shape, e.g. in a tubular sleeve, immersing the compressed lens in an eye compatible liquid, e.g. water, freezing the liquid in situ to form a generally cylindrical frozen plug, and inserting the frozen plug, containing the compressed lens therein, through the incision into the interior of the eye, e.g. by positioning such sleeve external to the eye at the incision and pressing the frozen plug by a plunger in the direction of the eye so as to force the plug out of the sleeve and in unconfined condition through the incision, such that the inserted plug will thaw in the eye interior and release the lens to its original, undeformed state, whereupon the original state lens may be seated in place in the eye.

Abstract: Poly(butylene terephthalate) is prepared in a two-stage process wherein terephthalic acid and 1,4-butanediol are esterified in the presence of a catalytic amount of a catalyst having an organo-metallic component which is an organo-titanate compound, an organo-tin compound or a combination thereof and a salt component which is an organic acid salt or an inorganic salt. In a second step, the esterification product is subject to polycondensation. By following the foregoing procedure, the formation of tetrahydrofuran is significantly suppressed and the percent conversion of esterification products increased.

Abstract: Contact lenses can be cleaned effectively in a short time, by using a kit for contact lens cleaning which comprises an oxidizing agent for removing stains adhering to contact lenses and a reducing agent for making nontoxic the oxidizing agent still remaining after stain removal and wherein the oxidizing agent and the reducing agent are each in such a form that when they are placed in water substantially simultaneously, the major portion of the oxidizing agent dissolves in the water more rapidly than the major portion of the reducing agent. Further, with this kit, the cleaned contact lenses can be made nontoxic without fail.

Abstract: A carding machine has a toothed takerin (4a) for taking fibre to be carded from a feed arrangement (3a) to a main carding cylinder (5a). The fibre is conveyed on the lower arc of the takerin, and a substantially rigid, flat plate (10) lies below the lower arc of the takerin. The plate extends across the full width of the takerin and terminates in a free edge facing into the direction of roation of the takerin and substantially parallel to the takerin axis. The free edge is spaced from the tips of the teeth on the takerin by a distance of not more than 5 mm, and the plate lies in a plane that makes an angle of from 75.degree. to 120.degree. to that radial plane of the takerin that intersects the free edge of the plate.

Abstract: A horizontal deflection stage for a raster scan device (e.g. a television receiver or a monitor) comprises a deflection generator, a d.c. supply regulator for the deflection generator, a voltage controlled oscillator providing drive pulses to the deflection generator, a phase detecting circuit for locking the oscillator to applied horizontal synchronizing pulses, and a sweep circuit for sweeping the oscillator through a range of frequencies until it achieves phase and frequency lock with the applied horizontal synchronizing pulses. An input to the regulator serves to control the output voltage of the regulator in accordance with the frequency to which the oscillator is locked. Thus the horizontal deflection stage automatically adjusts the horizontal timebase, and the regulated voltage supply of the deflection generator, in accordance with the frequency of the applied horizontal synchronizing pulses, without any operator adjustment being required.

Abstract: A method for preparing an alcohol insoluble polymide membrane. An appropriate membrane-forming casting liquid containing the required polyamide is evaporated under conditions of high total humidity and an air flow of less than 305 m/min. (1000 ft/min) in order to form the membrane. Membranes of a single polyamide, e.g. Nylon 6,6 can be formed by the method.

Abstract: A process of packaging goods, especially foodstuffs, comprising enclosing the goods in a sheet of thermoplastics material, preferably a bag, so as to form a package which presents two unsealed juxtaposed surfaces. The package is then placed in a container, one wall of which is made of deformable sheet material, preferably a sheet made of a silicone resin, which is stable at the sealing temperature of the thermoplastics material. The container is then connected to a source of vacuum and when the pressure has been reduced in both the container and the bag sufficient heat is applied to the deformable sheet in the vicinity of the juxtaposed surfaces to cause them to become sealed together. In a further embodiment of the invention vacuumization of the container including the bag is followed by the injection of a preserving gas such as carbon dioxide.

Abstract: A multi-needle sewing machine has a workpiece feed mechanism which includes first and second side supports located to opposite ends of the needle bar. A plurality of shafts extend between the side supports at locations spaced from the front region progressively rearwards towards the rear region of those supports. A plurality of transversely spaced endless belts pass around front and rear rollers rotatably mounted on foremost and rearmost ones of the shafts. Intermediate shafts carry respective front and rear guide rollers which guide an upper run of the conveyor belt to lie adjacent to a lower run of that belt and below the needle bar. The belts are driven so that the lower runs thereof travel from the front towards the rear of the side supports.

Abstract: A process for defining isolation structures between active regions of an integrated circuit is disclosed. The technique includes first forming a thermally grown silicon dioxide layer. A polysilicon layer is then deposited over the silicon dioxide layer and a silicon nitride-I layer is deposited thereon. A photo-resist mask is then formed on the top of the laminate and selective anisotropic dry etching is used to remove the unmasked silicon nitride-I and polysilicon layers. This step is followed by an isotropic dry etching to undercut the polysilicon beneath the silicon nitride-I layer. After the photo-resist masks and unmasked pad oxide are removed, a layer of silicon nitride-II is deposited. Thereafter, an anisotropic dry etching step is performed to remove the unmasked silicon nitride-II completely. An implantation step is then optionally performed.
