Abstract:
An automatic strainer assembly for straining a slurry comprises an inlet for receiving the slurry, a horizontally disposed strainer body in fluid communication with the inlet, and a rotatable strainer member received within the body having an inner surface and an outer surface. The strainer member defines a plurality of passageways for strained fluid to pass therethrough. A scraper is positioned substantially adjacent to and contacting the outer surface of the strainer member for removing material from the outer surface of the strainer member. A collection vessel is positioned substantially below the body for receiving material scraped from the outer surface of the strainer member. This collection vessel can include a transport member for returning this scraped material to an initial slurry supply for reprocessing thereof. An outlet is provided in fluid communication with the horizontal strainer body to expel the strained slurry.
Abstract:
Binoculars having a prism assembly between the objective and ocular, wherein the prism assembly is secured on a prism holding device by means of a permanently elastic sealing compound.
Abstract:
In an eye cup for an eyepiece of an optical observation apparatus, for individual and convenient adjustment of the eye cup it is provided that a second adjusting element can be rotated in a mode dependent on a compressive force independently or together with a first adjusting element, such that a light-shield section can be positioned as desired for any distance of the adjusting elements with respect to one another.
Abstract:
An imaging optical device, in particular binoculars or a telescope, comprises, in addition to a casing, an optical system with at least two optical components, the distance of which relative to one another is adjustable for focus setting of the optical system. This adjustment is effected by an adjusting device, which is coupled with at least one of the two components. The position of the optical components relative to each other is detected and, by the aid of a processor, converted into a focal length of the optical system and then outputted as a focal length via an output device. In this way, the distance of an object sighted by the optical device can be determined conveniently.
Abstract:
A cup for an eyepiece of an optical observation instrument, comprises a peripheral wall which includes an eyepiece-connecting section for connection of the cup to an eyepiece, a transition section which adjoins the eyepiece-connecting section, a light-protecting attachment which, by way of a sectional part of the transition section, is joined to a side of the transition section that is turned away from the eyepiece-connecting section; a sight hole which is laterally defined by the peripheral wall; the peripheral wall being movable into a first, non-folded end position for someone who does not wear spectacles for preclusion of any incidence of stray light upon an eyepiece lens, and into a second, folded end position for spectacle wearers; and into a third stable position of ventilation, located between the first and the second end position, for someone not wearing spectacles.
