Patent CH-677406-A5 (CH)
Title: Measuring technique for size of particles in medium - using varying transmission coefficient which is function of particle size
Inventor: BUGMANN GUIDO
IPC: G01N21/59
Filed: 1988-07-20
Abstract: The size measurement technique makes use of the fact that the transmission coefficient through a medium is related to the size of the objects within the medium, such that the coefficient increases with the size of the objects by comparison with the dimensions of the beam. The known relationship between transmission coefficient and object size allows auto-calibration of the measurement system. USE/ADVANTAGE - By using either waves or particles, it is possible to measure objects such as bubbles of gas in a liq., or holes in a cheese, gravel on a conveyor belt, or spots of paint without physical contact.

Title: Internal formwork element for a construction which is elongate in the vertical direction
Inventor: SEILER EDOUARD
IPC: E04G11/08
Filed: 1983-06-02
Abstract: The formwork element comprises panels (1) and connection parts (2) which alternate and are contiguous. They form together a continuous formwork surface for the inner face of the construction portion to be built. An internal frame (3) in the shape of a right parallelepiped, which is set back with respect to the said continuous surface, carries the panels (1) and the connection parts (2) on retractable supports (4', 4''). The frame (3) preferably rests on a base, itself bearing on pivoting parts, the ends of which can bear in cavities in the portions which have already been built. Such an arrangement enables the whole internal formwork element to be moved as a block by a single movement of the site crane, during the advancing from one portion to the next. <IMAGE>

Title: Electric cct. components containing module - uses rod-shaped hollow body for holding component groups for casting into hardenable plastics
IPC: H05K3/28
Filed: 1974-10-03
Abstract: The module, containing electric circuit components, is manufactured by embedding a whole strip of such components e.g. capacitors, resistors etc., in a long hollow mould body for casting in hardenable plastics. The mould has a U-shaped body and is closed at its ends so that the plastics resin can be poured in through the open top. After the resin has hardened the individual components are cut from the mould. The ends of the cut-off components modules are closed by a U-shaped bracket that has holes in the bridge piece for the components terminal wires. Before casting in resin the components are fixed onto a long support strip.

Title: Process for the production of fibrillated structures made of synthetic resin
Inventor: VOITURON GEORGES
IPC: D01D5/40
Filed: 1976-10-28
Abstract: Fibrillated structures made of synthetic resins such as polyolefins are obtained by sudden decompression of a mixture of molten polymer and solvent. The mixture additionally contains a monomer capable of being grafted onto the resin, such as maleic anhydride. The decompression is performed through an appropriate orifice at elevated pressure and temperature conditions. The fibrillated structures obtained are employed together with cellulose fibres, towards which they exhibit good reactivity. Papers manufactured in this way have an excellent breaking length.

IPC: B31B1/00
Filed: 2002-03-28
Abstract: The support bar (11) has fixing heads (14) projecting from its upper surface. Each head has a fish-hook type barb (17). These are introduced into holes (6) formed in the underside of the tool plate (10), and becomes embedded in the underside of the tool plate, thus retaining it in position.  The support bar (11) has upper (19) and lower (20) surfaces, with a number of fixing heads (14) projecting from its upper surface. Each head includes a straight sided section (15) with a conical section (16) above. The conical section is narrower at the top and wider at the bottom, such that it is wider than the straight section, thus forming fish-hook type barbs (17). These are introduced into holes (6) formed in the underside of the tool plate (10), the holes having been formed by laser machining. The barbed support heads become embedded in the underside of the tool plate, thus retaining it in position. The tool plate may be made of wood, enabling rapid and accurate laser machining of the holes.
