Title: Placing and retaining device - for vaginal medicaments
IPC: A61M31/00
Filed: 1971-05-17
Abstract: The device consists of two coaxial tubes, one of which can slide inside the other; the outer tube contains a cylindrical element of compressed cotton to act as an absorbent. In prior art infections of the lower female genital organs have been treated by the simple introduction of medicaments, in the form of ovules, by hand, or by the use of foams and ointments introduced by means of a syringe. In the new device the cotton acts as an absorbent for liqs. and undergoes a large increase in vol.; this element can be arranged to hold >=1 medicament so that it can be liberated, in a progressive manner, and, by its increase in vol., maintain this charge at least partly in contact with the parts to be treated. As the flow of the medicament is slow and prolonged, it can act for a long time on the vaginal walls; at the same time any local secretions in the neighbourhood can be absorbed by the cotton. A cord is provided in the element so that the latter can be withdrawn after use.

Title: Glass sheet cutting appts moving at high speed - comprises cutting tool carriers moving in sequence along a support beam across the glass
Inventor: WIT URBAIN DE
IPC: C03B33/10
Filed: 1975-06-02
Abstract: Method of and appts. for cutting sheet glass as it is produced from a continuous ribbon or sheet is claimed in which at least one cutting or marking stroke is made along one or more predetermined lins by means of at least one tool displaceable the length of a guide itself, associated with a guiding device, while the sheet is itself moving in its own plane, characterised in that after the cutting or marking operation, by the tools associated with the guide, the guide is removed from the cutting or marking lines and another guide takes its place to mark or cut at subsequent places. The cycle time between cuts is considerably reduced so that the mechanism can be operated on glass sheet advancing at any predetermined velocity, e.g. 600-800 metres/hr. cf. 200 m/hr. of a prior art cutters of this type. It is also possible to change the cutting programme without stopping the plant and without changing the production rate since only the guide device need be altered.
