Patent WO-7901028-A1 (WO)
Inventor: BUCHER W
IPC: E05B41/00
Filed: 1979-05-03
Abstract: It is necessary for the doors of prison cells, of sales, as well as the doors of armoured boxes and cupboards, to protect the switch which is mounted on the door or on the frame and which, by the closing motion of the door, releases a signal, against the manipulation by non authorized people, for example releasing of false signal by a prisoner when the door of the cell remains open. For this purpose, a signal switch (3) with contact roller (16) is fixed to the door (1), a fixed eccentric disc (4) working as the actuator of the switch being removably attached to the frame (2). This mechanical switch device (3, 4, 16) is arranged into a box (5) of which the base (6) is welded to the door (1) and the dome-shaped cap (7) is locked from the inside to the base (6) of the box by means of a cylinder lock (8) arranged in the box, for preventing the removal thereof. In the case of an optical device, an infra-red ray transmitter (35) and a ray receiver (36) with an interrupter transistor (49) are arranged inside the door, respectively the frame, or vice versa. The infra-red beam (41) is transmitted to the receiver (36) through two openings (39, 40), of the door (1) and of the frame (2), which are in alignment only when the door is in a closed position, causing the release of a signal.

Abstract: Le détecteur comprend au moins un corps en quartz (1) découpé dans un cristal de quartz, une fibre de verre reliée au corps quartzeux, au moins dans une section linéaire, et des moyens pour détecter des déformations linéaires de la fibre de verre, générées dans un champ électrique par des déformations du corps quartzeux, d'origine piézoélectrique. L'invention révèle comment la variabilité généralement indésirable du signal de mesure du détecteur, due à la température, peut se laisser influencer purement passivement par un mélange des coefficients piézoélectriques d11 et d14 participant à la modification dimensionnelle d'origine piézoélectrique du corps quartzeux, voire être éliminée.

IPC: C08G63/78
Filed: 1969-01-11
Abstract: Terephthalic acid is polycondensed, in a first reaction zone, with a mixture of bis-(hydroxyalkylene)-terephthalate and oligomers thereof so as to obtain a precondensate; a part of the precondensate obtained is then polycondensed in known manner; and the remainder of the precondensate is then re-esterified, in a second reaction zone, with the aid of added glycol so as to obtain bis-(hydroxyalkylene)-terephthalate and oligomers thereof; and the mixture obtained is finally recycled to the first reaction zone. This method avoids known disadvantages of direct reaction of terephthalic acid with glycol or transesterification of a terephthalate.

Title: Strong magnetic field generation inside conductors
Inventor: PETER WILHELM
IPC: H01B7/30
Filed: 1970-03-07
Abstract: Method of producing a strong magnetic field inside polished and insulated metallic conductors so as to "drown out" the effect of weak magnetic fields (e.g. the earth's magnetic field), involves using non magnetic conductors, e.g. a mixture of Pb and Sn to bring the current to the appts. For voltages up to 500 V the polished conductor wires may be tinned and insulated with a thin layer of rubber. For voltages of 20 - 220 KV the centre of the wire has a magnetic core insulated and non-electrostatic paper insulation free from hair wool or urea plastics, soaked in resin free oil and reinforced with glass fibres. This is covered with a tin or lead layer with a wall thickness of 1.5 to 3mm and is not earthed. This is covered with high duty plastics insulation e.g. polyethylene, PVC, polyester or other synthetic resin. High pressure gas filled cables may be used.

Title: Measuring spools for winding faults - diameters of foot, tip of spool compared withpredetermined reference values
Inventor: RAASCH HANS
IPC: B65H67/06
Filed: 1971-10-05
Abstract: To determine whether a spool has a winding fault e.g. due to being placed incorrectly on the spindle, the tip and foot of its spool are automatically measured prior to orientation in a doffing machine. As the spools are conveyor-fed towards the machine, they pass between fixed and movable feelers. The motion of the movable feeler is amplified and compared with a reference value. The sum, difference or ratio of tip and foot measurements can be compared with a reference value. The reverence value can be changed. Faulty spools can be ejected from the conveyor.
