Title: Apparatus for Levelling a Surface
IPC: E01C19/40
Filed: 1981-01-28
Abstract: Levelling apparatus comprising a smoothing board (51) suspended swingably on two pairs of pivotably interconnected struts (52, 53). The pairs of struts (52, 63) are pivotably connected by means of pivot pins (55, 56) to brackets (57, 58) secured to the smoothing board (51), the brackets being provided with slots (59, 60) at right angles to the board face (51a). A strut (52) also comprises a slot (61) in its longitudinal direction. The struts (52, 53) are also pivotably connected to a pair of rocking levers (54) themselves articulated to a trolley (44). An endless drive with a chain (47) for the trolley (44), and a vibrator drive (66) with eccentric and connecting rod (67) causes the smoothing board (51) to carry out a laterally guided oscillating movement composed of two individual movements which are at right angles to one another. Through the freely mobile swingable suspension arrangement the smoothing board works only in the region of the cement slurry and produces a smooth surface on a concrete slab put down by a finisher and evened-out as regards irregularities without the roughness having to be evened-out subsequently. The apparatus is intended for use more particularly with sliding-shuttering concrete finishers. <IMAGE>

Title: Component elements of tights
Inventor: PROTASONI MARIO
IPC: D04B9/46
Filed: 1982-06-29
Abstract: A tubular textile 20 produced by the needle-cylinder (or cylinders) is discharged through a tube 12 (the so- called duct) towards the calender 14 which acts to maintain the knitted textile under tension and to insert it into the hose-collecting reservoir 16 beneath it, all of which rotate in synchronism with the needle-cylinder or cylinders. A flattened shaping element is inserted into the textile above the calender, the upper part of the shaping element being inserted in the duct and being centered therein. The lower part bears, with the interposition of the flattened tubular textile on the hose- drawing rollers of the calender. The lower part of one of the longitudinal edges of the shaping element has a vertical section which lies further from the axis of rotation than the other points on the shaping element. Consequently, during operation of the machine, the said vertical section and the knitted textile which covers it move along a cylindrical surface. This creates the possibility of cutting the textile with the aid of an incandescent electrical resistance 34. This takes place at each revolution of the shaping element when the resistance is held in a position in which it is touching the said cylindrical surface. The cutting is stopped on movement of the resistance away from the cylindrical surface. The variation of the position of the resistance and its heating are controlled by cams 37, 45 carried by the main drum of the machine, in its turn driven by the chain which establishes the duration of the cycle. <IMAGE>

Title: Temperature compensated gas spring
Inventor: SMITH RICHARD C
IPC: F16F9/02
Filed: 1983-08-15
Abstract: A piston cylinder gas spring uses a combination of fluids to achieve a spring force which is more nearly constant with change in temperature than it would be if a single fluid were used. A primary pressure source is located within the casing (in chambers 26, 34) and acts against the piston 24 to urge the rod 30 out of the casing. A secondary pressure source is located within the casing (in chambers 28, 36) and acts against the piston to urge the rod into the casing. The primary pressure created by the primary pressure source is greater than the secondary pressure created by the secondary pressure source, and the percent change of the secondary pressure with temperature variation is greater than the percent change of the primary pressure with the same temperature variation. The primary source is nitrogen. The secondary source is a two phase liquid/vapour system e.g. acetylene, freon, ammonia, hydrogen bromide, sulphur hexafluoride. <IMAGE>
