Abstract: A filter assembly (1) comprises a fluid tight housing (6, 7). First and second coupling means (10 and 11) are provided on the housing, each coupling means providing adjacent flow channels into the housing. A filter element is located within the housing, the element having a fluid tight external wall (20) and a filter medium (19) housed within the wall. A first flow path is established between the first and second coupling means through the filter element, while a second flow path between the first and second coupling means is established within the housing but outside the external wall of the filter element.

Abstract: With the object of providing a glass run channel which can accommodate the curvature in both front elevation and plan, and also some degree of twisting, in this invention a glass run channel comprises a metal core of general S shape, the metal core having a continuous unbroken strip and a plurality of transversely extending slits forming between them bars or ribs extending transversely from the unbroken strip, the core being covered with an elastomer.

Abstract: A display unit comprising a light source, a beam splitter, e.g. in the form of a sheet of titanium coated glass, a layer of retroreflective material, a clear shelf and a flexible stencil so arranged that, in use, light passes through the stencil from the light source and is reflected by the beam splitter, e.g. titanium coated glass, onto the retroreflective screen. The layer of retroreflective material diverts the incident light, e.g. through 180 degrees, so that when a user looks towards the retroreflective material the image appears suspended in space. The stencil is larger than the clear shelf and consequently has an undulant surface which causes the image itself to be undulant and appear in three dimensions. A cranked shaft is attached to the stencil and is rotated by a motor. As the shaft rotates, the undulations in the flexible stencil alter, thereby causing the image to move.

Abstract: A joint prosthesis for use in long bone joint replacement comprises a tapering stem 4 upon which is located a collar 10 chosen from a range of similar collars having different internal diameters. The collar chosen locates with the stem at a particular height, depending on the internal diameter of the collar and the tapering of the stem.

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.

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 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.
