Patent FR-2212642-A1 (FR)
IPC: H01L21/60
Filed: 1973-10-02
Abstract: A dual-in-line plastic package for an integrated circuit is assembled with the use of a thermal stress-resistant thin-film interconnect pattern on a flexible insulator film. All electrical connections to the semiconductor chip are made simultaneously by bonding directly to the thin-film interconnect pattern. Each segment of the interconnect pattern is then connected simultaneously to a simplified external lead frame, by means of a novel soldering technique. The assembly is then ready for plastic encapsulation and final trimming. By supplying both the flexible interconnect pattern and the external lead frame in continuous coils or reels, a high degree of handling simplicity, speed and accuracy is achieved with a maximum opportunity for automation, to produce a low work content product.

Title: Ampoule for automatic injection - operates by compressed gas separated from liq. by moving piston
IPC: A61M5/24
Filed: 1974-02-13
Abstract: Ampoule is used in a special instrument and is operated by means of a compressed gas. It consists of a cylindrical press. bottle with a moveable piston which separates the liq. compartment from the gas compartment. The lower end of the bottle is closed by a rubber stopper. Finger grips are provided to facilitate and controlled forcing of the bottle in needle has two bevelled, spear-shaped ends as used in dental work and is fixed in the instrument by a rubber locking cone. The syringe assembly is intended for use once only. As the ampoule has no neck which has to be broken, there is no risk from glass fragments entering the patient's body. It can be operated almost in the horizontal position without any gas bubbles escaping into the patient's body. For use, the bottle is pushed, against the spring, in the direction of the needle so that the end opposite that which enters the patient penetrates through the stopper into the bottole. An opening communicating with the atmos. is thus established so that the gaseous phase, under press., propels the liq. through the needle into the patient.

Patent FR-2302238-A1 (FR)
Title: Packing articles using printed heat shrinkable film - by placing protective masks over printed areas during shrinking to prevent distortion
IPC: B65B53/02
Filed: 1975-02-26
Abstract: Articles are wrapped in heat shrinkable film for packing and placed on a conveyor. The printed areas on the film are screened by protective masks which are part of the conveyor or fitted individually. Masks do not need to touch the film. Packages are passed through a heating tunnel. The protected areas, shielded from the heat, undergo minor shrinkage only. After leaving this tunnel, the masks are removed and the packages pass through a second heating tunnel of lower intensity. This removes the wrinkles and stresses between the protected and unprotected ares. The printing is unaffected by distortion.
