Patent BE-816780-A (BE)
Title: Extruded thermoplastic polyurethane films - prepd. by rapid cooling of the molten extrudate within specified temp range; good inherent antiblocking properties
IPC: B29C48/08
Filed: 1974-06-24
Abstract: The polyurethanes, made by reacting a diisocyanate with an aliphatic diol, opt. with subsequent chain lengthening with a low mol. wt. diol. are extruded into a sheet and the extruded sheet is cooled rapidly, e.g. on a cooling roller or in a water bath, at a temp. of 40-80 degrees C, esp. 50-60 degrees C. The resulting films are tough, abrasion resistant, chemical resistant and relatively gas permeable, and have inherently good anti-blocking props without the addn. of external additives. The films may be stretched mono- or biaxially, and are useful e.g. as packaging foils, in the prodn. of laminated films, etc.

Title: All-weather tidal lock complex - has two locks alongside each other connected by intermediate passages and sluices
IPC: E02C1/00
Filed: 1974-08-14
Abstract: Two large locks, each with two large sluice gates, are mounted alongside one another and operate together so that in turn one allows ships to leave the high water side and the other the low water side, being situated half in the high and half in the low water zone. Between the locks are two canals, one connected to the high water and one to the low water side by a sluice, and separated by a cross-wall. Other sluices connect them to the locks, to give rapid filling and emptying, and the locks can also be connected through them to each other, so that the water drained from one is used for half-filling the other.

Title: Screw type lamp base for two level illumination - uses adaptor with triac power controller and control circuit which toggles between full and part power at alternate on-switching
IPC: H05B39/08
Filed: 1982-09-22
Abstract: The lamp base insert screws into an Edison screw type lamp base and has provision to accept a screw type lamp. An electronic controller circuit it interposed between the male and female screw connectors. The electronic controller permits two levels of illumination from the lamp, toggled from one level to the other by switching off and immediate re-switching on at the wall ON/OFF switch. The electronic circuit uses a triac as the main power control element. The triac is either operated fully on by holding the gate high, or in conventional phase control mode using a series resistor-capacitor phase shift circuit. A digital logic circuit connected to the gate acts as a toggle flip-flop to determine the mode of operation. The electronic circuit is housed in a bakelite annulus (4) surrounding the female connector (2). At turn-off, the lamp remains lit at the low level for a time delay of a few seconds.

Abstract: METHOD AND APPARATUS FOR THE ASSEMBLY       OF SEMICONDUCTOR DEVICES     ABSTRACT OF THE DISCLOSURE         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 inter-connect 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.

Abstract: ABSTRACT OF THE DISCLOSURE:         The invention relates to an arrangement provided with a gas and/or vapour discharge lamp which is stabilised with a series arrangement of an inductor L and a capacitor C.         According to the invention the lamp has an operating voltage which is less than 20% of the voltage of the alternating voltage supply source; a stable operation of that lamp is possible when the values of L and C are so adjusted that there is a resonance between 3.5 and 4 times the frequency of the alternating voltage source. This means that the inductor may be small.

Abstract: ABSTRACT:              The extraction method employs the repelling and attractive forces of liquids relative to-each other and relative to the material of an extraction tube. Oblong drops of the one liquid surrounded by the other liquid are rolled through a narrow tube of a few millimetres, resulting in a large contact area and an internal stirring in the drops, so that a very high extraction efficiency is obtained.          An extraction apparatus is described which is particularly suited for stationary or mobile water-pollution measuring stations.
