Title: Method of and apparatus for manufacturing a foam tube having a fastener.
IPC: B29D23/00
Filed: 1982-10-08
Abstract: A process for the continuous manufacture of a closable pipe slotted in the longitudinal direction which is made from a sheet of a thermoplastic foam material involves shaping the sheet in the heated thermoelastic and/or thermoplastic state at right angles to its longitudinal direction into a pipe cross section, and applying the strips of a closure, especially a slide fastener of a thermoplastic synthetic resin, to the mutually facing longitudinal edges of the pipe slot by means of welding, heat-sealing, cementing, or the like.

Title: Ablative photodecomposition of organic biological material.
IPC: A61B18/20
Filed: 1983-11-21
Abstract: Photoetching organic biological matter is effected without requiring heat as the dominant etching mechanism. Farultraviolet radiation having one or more of wavelengths less than 200 nm is used to selectively remove organic biological material, where the radiation has an energy fluence sufficiently great to cause ablative photodecomposition i.e. bond-breaking and resulting generation of volatile or gaseous products which "explode" away from the irradiated material. Either continuous wave or pulse radiation can be used, a suitable ultraviolet light source being an ArF excimer laser having an output at 193 nm. The exposed biological material is ablatively photodecomposed without heating or damage to the rest of the organic material. Medical and dental applications include the removal of damaged or unhealthy tissue from bone, removal of skin lesions, cutting or sectioning healthy tissue, and the treatment of decayed teeth.
Patent ES-8407128-A1 (ES)
Title: Thread cutting device for sewing machines
IPC: D05B65/00
Filed: 1983-11-29
Abstract: A thread catcher of a cutting device in sewing machines is actuated by an air cylinder whose piston has two portions of unequal diameter. The small cylinder space accommodating the smaller-diameter piston portion is permanently pressurized while the larger cylinder space is alternately pressurized and vented. The larger cylinder space portion on its end closer to the smaller piston portion is permanently vented through a conduit. Both this conduit and the conduit for supplying the larger cylinder space include a throttle. The obtained effect is that the first step of motion of the thread catcher is quick and exact in duration, while the second step of motion is slower but performed with a greater force, so that thin threads are prevented from tearing prematurely and thick threads are cut reliably.

Title: Control circuit for an ink jet printing element and a method of dimensioning and manufacture relating thereto.
IPC: B41J2/045
Filed: 1986-04-30
Abstract: A control circuit (17) applies a voltage pulse to a piezoelectric transducer (16) to create pressure in a chamber (10) open to an ink reservoir (14) at one end and closed by an ink nozzle (13) at the other. The control circuit (17) generates a pulse formed by one or two waves, each comprising a secondary portion delayed relative to the primary portion by a time which is double the reflection time that is characteristic of the chamber (10), thereby cancelling reflection of the drop expulsion pressure. The form of the wave is determined by a series of variable resistors disposed in the circuit while the time is regulated by an element for regulating the period of oscillation of the circuit. Alternatively the form of the wave is recorded in digital form in an ROM addressed by a counter while the period of oscillation is regulated by acting on a timer for controlling the counter.
