Abstract: A honeycomb structure as a substrate for a catalyst has at least one partially melted surface on an outer surface of the structure. A roughness of the melted surface is coarser than other surfaces. With the coarse surface, shifting of the honeycomb structure in through-aperture directions and rotation about its axis are prevented, thereby enhancing the reliability of a catalyst converter incorporating the honeycomb structure therein. A method of producing the honeycomb structure includes steps of, after extruding a ceramic batch into a honeycomb structure, drying the extruded honeycomb structure, attaching a chemical compound having a low melting point at a predetermined position onto an outer wall surface of the dried honeycomb structure, and firing the structure to melt at least a part of the outer wall surface, thereby obtaining the honeycomb structure having a melted portion whose roughness is coarser than the other surfaces of the outer wall.

Abstract: The franking machine has a control console (50) on which is provided a number of keys (21-24) corresponding to the decimal places of a maximum franking value amount. The most frequently occurring franking value amounts and also surcharge amounts for special letter dispatch types are predetermined in fixed manner by programming a control unit of the franking machine and are associated with the said keys (21-24) and additional keys (25, AIR, EXP, REG), so that the entry of a complete franking value amount by pressing a single key is possible. The franking machine can be switched between two entry modes by a special key (D-SET) and these modes are performed by means of the same keys (21-24). If exceptionally a franking value amount is to be entered in the franking machine and which does not correspond to one of the fixed, predetermined franking value amounts, entry takes place after operating the switching special key (D-SET) separately by stepwise entry via the keys (21-24) associated with these decimal places.

Abstract: A flexible hose (1) mounted over a hollow member (2) has within its portion that is mounted over the hollow member a lip seal (5) extending all around the inner wall of the hose. The lip seal (5) extends away from the inner wall obliquely to the wall in the direction away from the adjacent end of the hose (1) and is disposed between abutments (3,4) extending away from the inner wall of the hose and engaged with the hollow member (2). Prior to assembly, the lip seal (5) projects further into the interior of the hose (1) than the abutments (3,4) so that in the assembled condition the lip seal is pushed outwardly by the hollow member with a gap (6) left between the opposing faces of the inner wall of the hose (1) and the lip seal (5). A fastener (8) secured around the end portion of the hose (1) holds the abutments (3,4) fast against the hollow member (2) with the abutments protecting the lip seal (5) from the effect of this securing force. It is the lip seal (5) that seals against internal pressure that acts on the lip seal to reinforce the sealing action of this seal.

Abstract: An apparatus (20) for measuring the thickness of a thin film layer (32) on substrate (28) includes a probe beam of radiation (24) focused substantially normal to the surface of the sample using a high numerical aperture lens (30). The high numerical aperture lens (30) provides a large spread of angles of incidence of the rays within the incident focused beam. A detector (50) measures the intensity across the reflected probe beam as a function of the angle of incidence with respect to the surface of the substrate (28) of various rays within the focused incident probe beam. A processor (52) functions to derive the thickness of the thin film layer based on these angular dependent intensity measurements. This result is achieved by using the angular dependent intensity measurements to solve the layer thickness using variations of the Fresnel equations. The invention is particularly suitable for measuring thin films, such as oxide layers, on silicon semiconductor samples.

Abstract: Method and device for establishing and/or checking the condition of a technical component of a vehicle, in particular the tyres for the tyre air pressure and/or the shock absorbers for shock absorber defects by measuring vibrations introduced into the chassis of the vehicle on components of the wheel suspension in relation to the bodywork. In order to obtain the facility for establishing the state of the technical component during running, but without measuring sensors on the component itself, use is made of the fact that the condition, for example of the tyres, has an effect on the vibration behaviour of the components of the wheel suspensions. In order to detect changes in this vibration behaviour, values of the, in particular randomly excited, vibrations of components of different wheel suspensions coupled to the technical component are measured and these, where necessary converted, measured values are combined after transformation in a spectral chamber to form characteristic spectral values, which are compared with assigned spectral characteristic values previously established in a similar manner, determining deviations in a predetermined vehicle-specific frequency range. It was found that the condition of various components coupled to the wheel suspension is reflected in different frequency ranges of the spectral characteristic curve.

Abstract: In an apparatus for spreading and cutting layups of sheet material pin mechanisms (72) are distributed over the supporting surface of the table (12) and include pins (74) moveable between raised and lowered positions to enable selected portions of the supporting surface to be adapted, or not, to a spreading procedure involving the pinning of each layer as it is spread. The supporting surface (20̸) is divided into sections (70̸) and the pin mechanisms (72) of each section are operated in unison by a control element (114) located on the side wall of the table with each control element (114) being aligned with its associated section (70̸) of the table so as to be quickly and easily operable by an operator without the operator having to give great thought or attention to which pin mechanisms (72) are operated by which switch. The pins (74) passing through a layup being cut by the cutter (24) are automatically lowered upon the cutter (24) approaching the pins to avoid collision between the pins and the cutter. This latter function can be defeated, if desired, to allow the cutter (24) to be passed over a layup in a noncutting mode without pins (74) being withdrawn from the layup.
