Title: Internally corrugated packaging sheet with all round stiffness - obtd by internal ribs in different directions in different layers
IPC: E04C2/34
Filed: 1974-04-30
Abstract: A composite plate of thermoplastics is constituted of two parallel outer layers each having on its inner face anumber of parallel ribs, the ribs of one layer crossing those of the other at an angle and being bonded to them. In a variant, there is an additional intermediate layer also having ribs on both its faces, these ribs crossing and being bonded to the inwardly projecting ribs of the outer layers. In yet another variant, there are two such intermediate layers on the same principle. The ribs of the outer layers are in general parallel within each layer, and may be straight on both outer layers, curved on both outer layers, or curved on one layer and straight on the other. The presence of ribs running in more than one direction gives the same stiffness against bending normally possessed by corrugated packaging material or the like, but in the present case stiffness in every direction.

Title: Ultrasonic welding tool with multiple heads set side by side - for welding wide sheet at narrow local zones
IPC: B29C65/08
Filed: 1974-09-26
Abstract: Ultrasonic welding tool for bonding superimposed sheets including thermoplastic materials, where the tool comprises several independent bar profile probes each with its own ultrasonic generator and aligned side by side across the line of the sheet so that the gap between adjacent tools is less than the width of any individual anvil surfaces on the support roll defining the pattern of welded zones. The tool is used for laminating sheets to make vehicle trims, tarpaulins, packaging materials etc. A high ratio of impulse power to probe area is more readily maintained without risk of cutting the sheet than by use of a single wide tool of correspondingly less depth. Simpler to align than systems involving staggered arrays of multiple tools to avoid either missing some anvils or double heating some zones. The tool is suitable for welding sheets of any width.

Title: Fallen nuts gathering machine - has blades discharging into turbulence chamber feeding sieves
IPC: A01D51/00
Filed: 1974-10-21
Abstract: The nuts are picked up along with stones and leaves. They are thrown by blades into the housing and reach a turbulence chamber. The air from a fan meets the air from the blades and causes turbulence, as a result of which the leaves are blown through a duct. The first and small stones pass through a sieve and then through a second sieve which sends them to two more sieves. These let the stones through while the nuts arrive at an auger by which they are conveyed to the bagging off point. Two discs turn in opposite directions, bringing the nuts to the centre line of the machine. A guard arm acts upon a disc arm in such a way that it moves on a disc away from the obstruction.

Title: Texturing continuous filament textile yarns by compressed air - in process suited both to chemical and glass fibres
Inventor: SERILLON MICHEL
IPC: D02G1/16
Filed: 1975-05-07
Abstract: A thread of continuous filaments is treated by a jet of fluid under pressure, in a device having a lengthways running channel for the thread, with inlet and outlet openings. A duct for the fluid under pressure opens into the thread channel at an angle and between the connection of the feed duct to the channel and the thread outlet, there is an expansion chamber for the fluid. The channel for the thread is sectionalised and is cylindrical at the inlet with a second coaxial cylindrical section of larger dia. The expansion chamber is integral with the larger section of the channel but has a very much larger cross section, whilst the equally coaxial outlet of the expansion chamber is smaller in dia. than the second section of the thread channel. From a distribution chamber for the compressed fluid, a number of ducts open into the channel for the thread at an angle of about 30 degrees. Design uses much less compressed air. Allows much higher throughput speeds and reduces the number of broken filaments.

Title: Pneumatic spray painting process - uses classic colours diluted to nearly fluid state for stereoscopic effect
IPC: B44D2/00
Filed: 1975-05-21
Abstract: The decorating process uses paint applied with a compressed-air spray pistol. Classic colours are used and are diluted to render them nearly fluid while allowing a certain stereoscopic effect. Working can be at right angles to the surface to give the stereoscopic effect, or obliquely to give dashes or a dispersal effect. Successive colours applied to give a thickness can be arranged to harden slowly and merge together to provide a shading effect. The decorative effects can be applied to a paint base put on in the normal manner.
