Title: A method and apparatus for compressing a wood sample
Inventor: THOMASSEN THOMAS
IPC: B27K5/00
Filed: 1990-08-23
Abstract: A heated wood sample having a water content exceeding 20 percent is compressed axially in the direction of the grain or fibres of the sample in a compression mould. Oppositely directed compressive forces are applied not only to the end surfaces of the sample, for example by means of a hydraulic cylinder, but also to side surface parts of the sample as frictional forces.  The sample may be arranged within a compression chamber which is at least partly defined by longitudinally overlapping side wall parts, which  are  mutually  displaceable  in  the  longitudinal direction of the chamber, and these side wall parts may be pressed into frictional engagement with the sample for example by means of an inflatable bag or an inflatable hose section, and means may be provided for mutually displacing the side wall parts so as to apply frictional compressive forces to the wood sample.  The side wall parts or friction plates may engage with longitudinally spaced sections of the  sample,  if  desired.    However,  if  a  substantially uniform compression along the  length of the sample is desired, the side wall parts are preferably arranged in pairs of oppositely positioned wall parts each of which extends along substantially the total length of the sample. The hydraulic cylinder by means of which compressive forces are  applied  to  the  end  surfaces  of  the  sample,  may simultaneously  displace  one  pair  of  the  oppositely positioned side wall parts longitudinally in relation to the other pair of side wall parts.   The longitudinally compressed wood sample may be bent and shaped much more easily than a corresponding non-compressed sample.

Abstract: PHN 13696                                       15.04.1992 ABSTRACT: Method of manufacturing a semiconductor device comprising a capacitor with a ferroelectric dielectric, and semiconductor device comprising such a capacitor.     A method of manufacturing a semiconductor device whereby a capacitor (2) is provided on a surface (10) of a semiconductor body (3) with a semiconductor element (1) in that a lower electrode (11), an oxidic ferroelectric dielectric (12) and an upper electrode (13) are provided in that order, the upper electrode not covering an edge of the dielectric, after which an insulating layer (14) with superimposed metal conductor tracks is provided. According to the invention, the edge of the dielectric (12) not covered by the upper electrode (13) is coated with a coating layer (14, 20, or 30) practically imperviable to hydrogen, after which the device is heated in a hydrogen-containing atmosphere. Heating in a hydrogen atmosphere neutralizes dangling bonds which arise during deposition of the conductor tracks on the insulating layer, while the coating layer protects the dielectric from attacks by hydrogen. The semiconductor device then has a shorter access time.            Fig. 1.

IPC: E02D3/02
Filed: 1992-06-16
Abstract: A tamping shoe for a vibration rammer has a plurality of through holes communicating between an under surface and an upper surface. The through holes permit the escape of air trapped between the under surface and a surface being tamped, and thereby reduce the amount and pressure of air compressed under the tamping shoe. This reduces noise pollution produced during tamping. In a preferred embodiment, the through holes are tapered outward in the direction of air flow. Air passing through a through hole in a mount is released through a further through hole bored through a wall of the mount.
