Abstract: Proposed is an improvement in a vessel, e.g., crucible, of pyrolytic boron nitride (PBN) used, for example, in the process of molecular beam epitaxy for melting silicon and the like at a high temperature. Different from conventional PBN crucibles used for such a process, in which contamination of high-purity silicon is unavoidable by the reaction of molten silicon with PBN or a thermal decomposition products of boron nitride, the inventive PBN vessel is provided on the surface with a protective coating layer of pyrolytic graphite or a refractory metal such as platinum so as not to cause troubles due to contamination of high-purity silicon melted therein with the crucible materials.

Abstract: A device for decorative sewing of articles made of leather includes a longitudinal guide (7) a part of which is laterally delimited by two inclined flat surfaces (7a, 7b) upwardly convergent, forming at the top a tooth (10) on which an article (1) to be sewn is moved. A folding member (12), situated over the longitudinal guide (7), clamps the article (1) to the tooth (10), by folding this article (1) on the inclined flat surfaces (7a, 7b), when the needle (20) has formed a stitch (4). A leather pressing element (15) oscillates on a plane that is transversal with respect to the longitudinal guide (7) and presses the article (1) in position adjacent to the stitch 4 just formed, on the side where the needle (20) enters the article (1).
Abstract: A moisture absorbent material comprises a porous matrix of absorbent alumina, the volume of the pores of the matrix being between 60 and 90%, preferably 80 to 85% of the volume of the material. The average diameter of the pores is between 5.times.10.sup.-9 and 1.times.10.sup.-6 m.

Abstract: A retractable magnifier includes an enclosure and a frame slidably mounted in the enclosure. The frame is slidable between a retracted position and two extended positions. A magnifying lens is mounted in the frame such that the lens is enclosed by the enclosure when the frame is in the retracted position, and such that the lens is exposed when the frame is in the extended position. A light with electric terminals is mounted in the frame, and is connected through a pair of conductive springs to a power source. One end of one spring is slidable in a slot in the frame to engage a switch terminal to automatically switch the light on when the frame is extended, and off when the frame is retracted.

Abstract: The conversion system for a camera employs a conversion lever disposed at the outer side of a camera body to select a given photographic mode without need to open the camera. The conversion lever is used to shift a cam plate which is located within the camera body in order to effect vertical movement of two panorama curtains within the camera body. The cam plate may be moved into one of three positions, namely a normal photographic mode position, a first photographic mode position and a second photographic mode position. A first operating lever is actuated by the cam plate to move one panorama curtain vertically while movement of the first panorama curtain causes movement of the second panorama curtain via a second operating lever.
Abstract: A hydraulic tappet comprises an open-ended cylinder and a piston slidably accommodated in the cylinder. One end of the piston projects out of the open end of the cylinder and engages a valve rocker. A gear mechanism is provide to effect rotation of the cylinder about its axis whilst the piston remains stationary. An oil chamber is provided within the cylinder beyond the other end of the piston. A pressurized oil space is arranged to supply oil to the chamber via a non-return valve. An oil discharge space communicates with the chamber via a pathway including an opening in the cylinder wall. The pathway is interrupted by the piston as the piston moves into the cylinder. The oil discharge space is at a pressure substantially below that of the pressurized oil space. A plurality of spaced holes is arranged in a spiral line formed in the cylinder wall but only one of the holes communicates with the oil discharge space at any one time.
Abstract: The impact wall element (1) for gentle deceleration of a human body impacting an obstacle has a two-zone structure. The first zone comprises a lightweight, plastically deformable sandwich cover plate (10) with two thin cover layers (11, 12) and an intermediately positioned, lightweight, deformable support core (13). In the second zone are provided discreet, spaced, plastically deformable spacing elements (21), which carry the cover plate and are supported on a fixed substrate (5). The thickness D2 of the second zone is more than twice the thickness D1 of the first zone. The lightweight wall element leads to a gentle interception on the shortest possible path, particularly in the case of a head impact in motor vehicles or aircraft.
