Abstract: ABSTRACT         A foamed-glass granular material has a grain-size of between 0.2 and 3 mm between 106 and 107 gas cavities per cm3 of granular material and a bulk-weight of between 100 and 500 g/litre.  The diameter of the largest gas cavity is substantially less than 0.1 mm. The gas cavities are mostly, or exclusively, closed cells of the same order of magnitude.          The foamed-glass granular material may also contain up to 85% by weight of pumice, lava and/or tuff.  The said material is produced by grinding the raw materials into a flour, mixing the said flour with an organic and/or inorganic expanding agent which releases gas under the action of heat, forming from this mixture a raw granular material having a grain diameter of between 0.1 and 1.5 mm, and heating this material in a suspension or vibration furnace, for between 5 and 180 seconds, at between 600 and 900°C.  The foamed-glass granular material thus obtained is removed from the furnace before the  small gas cavities, initially produced during the expansion process) can combine to any great extent to form larger gas cavities.

Abstract: ABSTRACT OF THE DISCLOSURE           Briefly, the present invention is concerned with a low inertia scanning system for projecting an image of a stationary object on a flat platen onto a rotating photore-ceptor drum.  An aperture plate located adjacent the photo-receptor drum moves in a direction opposite the direction of the drum.  A carriage disposed between a stationary lens and the photoreceptor drum supports a pair of mirrors.  The light image is projected from the lens to one of the pair of mirrors for reflection to the second mirror rotating about a pivot point to scan the image through the aperture onto the photoreceptor drum.  During scanning of the platen, the carriage moves in a linear direction toward and away from the photoreceptor drum and together with the rotation of the second mirror maintains a constant magnification ratio. A second pair of mirrors disposed between the platen and the lens is adapted for movement in a linear direction with respect to the flat platen to predetermined positions in cooperation with the shifting of the lens to provide a properly focused light image in a different magnification range.

Title: Process for producing a filtering structure  in particular for cigarette filters
Inventor: COQ FRANCOIS
IPC: A24D3/14
Filed: 1980-07-25
Granted: 1982-08-31
Abstract: Abstract A filtering structure is made from a fibrous mass comprising an homogeneous mixture of fibres of different types.  Some of the fibres are thermofusible synthetic fibres having a low melting point and adhesive properties in the molten state, and the others are absorbent with respect to harmful products of tobacco smoke and stable at the melting temperature of the thermofusible fibres.  The fibrous mixture is shaped into a cylindrical rod which is in a state which is not yet coherent but homogeneous and comprises fibrous networks which are closely imbricated relative to each other.  According to the invention, the process comprises employing a substantial proportion of thermofusible fibres relative to the absorbent fibres, bringing the fibrous mixture to a temperature which leaves the absorbent fibres intact but which is high enough to melt and fluidify all the thermofusible material which, initially present in the form of fibres, is converted into fine droplets dispersed in the network of absorbent fibres.  This conversion creates, on one hand, multiple connections at the crossing points of the absorbent fibres, which remain stable and, on the other hand, a network of pores which intercommunicate in all directions and are constituted by the spaces left empty upon the melting of the thermofusible fibres.            This process is applicable in particular to the production of a filtering structure for cigarette filters.

Abstract: Abstract A lawn mower engine having a lightweight top rotor of low polar inertia drives a rotary blade through a clutch-flywheel rotor having sufficient inertia to provide the major flywheel effect for the engine.  Clutch faces at the rotor periphery engage a surrounding blade-carrier drum and have a maximum torque arm for positively driving the blade. The faces are preferably on centrifugal shoes which slip at load-reduced speed so as to maintain engine operation, and release at idling speed to allow engine starting with the blade stopped.  A brake band or ring about the drum is spring-pressed ON to stop the blade when a deadman control is released.  The preferred clutch-flywheel rotor is made of two heavy circular plates (e.g., 1/4" x 6") riveted together against spacer slugs and a shouldered hub.  Wide clutch shoes are mounted on such rotor by end tangs and springs between the plates.  The top rotor plate substantially closes the top of the drum.  Access and hub openings in the two plates provide rotor spacer slugs.  The drum is slightly smaller than the mower deck opening to permit preassembly to the engine, and permit mounting the brake band on the engine-mounting bolts.  The throttle lever in the path of the deadman lever is driven to idle position when the deadman lever is released.  The rotor carries a clicker which makes an audible noise if the engine is stopped while the brake is OFF and the blade runs free under its own momentum.
