Patent EP-0010386-A1 (EP)
Inventor: DAVIS RONALD PERCIVAL
IPC: E05C17/16
Filed: 1979-10-05
Abstract: A releasable retaining means for mounting on the inside of an outward opening closure element movable to open and close an opening. First and second mounting means (13 and 14) are respectively mountable on the closure element (11) and opening surround (12) with a stay (15) slidably and pivotably coupled to the second mounting means (14). Stay (15) is pivotably couplable by engagement means (22) to the first mounting means (13) and reteasabletherefrom by sliding stay (15) relative to mounting means (14) but only when the closure element is closed. Recoupling means (16, 24) automatically cause the engagement means (22) to couple to said first mounting means (13) when the closure (11) is moved into the closed position. 
     The retaining means thus prevents closure element (11) from opening more than a predetermined amount unless the stay (15) is released from the first mounting means (13) prior to opening the closure element (11). If stay (15) is released it becomes automatically recoupled on closing the closure element.

Abstract: A commutation circuit for an inverter using two parallelly connected main thyristors (TH1; TH2) alternately turned ON by pulse width modulation (PWM) for the generation of a fundamental sine wave, uses two separate but coupled primary (transformer)windings (W1; W2) associated with respective positive and negative thyristors with a common secondary winding (W6) at the output, and two commutating networks for the respective poles, each including an auxiliary thyristor (THP; THN) for fixed-commutation and the resonant combination of a capacitor (C3; C4) and an inductor (Ll; L2). The thyristors, the commutating networks, the DC source, and the output transformer have a symmetrical disposition as well as symmetrical commutation steps.

Abstract: The feeding machine receives a plurality of articles from the delivering machine at the respective speed, lifts these up and brings them to the processing speed of the machine to be fed and transfers them to the latter. This specifically takes place by the article receivers (8) being brought by a mechanism (4) to the same speed as the articles (1), (2), (3) which are guided individually on the delivery conveyor (5). After reaching the speed, the article receivers are lowered onto the articles, the latter are received, lifted up, moved over the article dispatch conveyor (6), aligned with the speed of the dispatch conveyor, lowered and released. The article receivers are designed in such a way that unsatisfactory objects are not received, with the result that they cannot disturb further processes. The mechanism is driven in angular synchronism with the preceding and following machine.

Abstract: A read only memory (ROM) comprising word lines (WLi, WLj, WLk), bit lines (BLI, BLm) virtual ground lines (VGL, VGm) and memory cells (CLi, CLj, CLk) of FETs arranged on intersections of the word lines and bit lines. A gate of each cell is connected to one of the word lines. A drain of each cell is connected to one of the bit lines. A source of each cell is connected to one of the virtual ground lines. According to the invention, particular cells storing information "0" are depletion-type transistors, the threshold voltage of which being lowered by ion implantation. When ROM is in operation with respect to the memory cells on a selected bit line, the potential difference between a selected word line and a selected virtual ground line is enough to turn on the depletion-type cell but not enough to turn on the other cells and, the potential difference between a nonselected word line and selected virtual ground line is not enough to turn on the depletion-type cell.

Abstract: A method and apparatus for manufacturing tea bags and the like is disclosed. The bags are made by forming a web into a flattened closed tube while continuously introducing tea and the like into the tube and pinching the tube at successive locations along transverse pinch lines corresponding generally to the required bag length. The tube is then caused to travel upwardly so that the tea tends to migrate downwardly under gravity and creates voided areas below the pinch locations and the tube is then heat sealed transversely in those voided areas. Finally, the bags are severed from the tube along lines disposed generally centrally of each transverse heat seal.

Abstract: Conversion digital/analogique, pour la conversion de signaux digitaux en signaux analogiques correspondants. Ce systeme s'applique particulierement a une conversion digital/analogique a haute resolution. Dans un mode de realisation particulier, une serie en cascade de diviseurs de tension individuels (20-23; 38-41 et 56-60) est utilisee pour diviser un signal de reference de tension avec une resolution toujours plus elevee. Des amplificateurs-suiveurs de tension (33, 36, 51, 54) sont utilises entre les etages diviseurs individuels pour eliminer sensiblement tout effet de charge sur les sorties des etages diviseurs individuels. Le schema de connexion est tel qu'une seule connexion a l'interieur d'un etage diviseur sera commutee pour une transition entre deux signaux digitaux adjacents et deux niveaux de signaux analogiques adjacents. Le resultat est une resolution utile, qui correspondra normalement au nombre d'etages diviseurs, meme si l'exactitude et l'adaptation des composants et la precision absolue de conversion ne sont pas aussi precises. Cette realisation peut etre utilisee egalement dans la mesure ou conversion analogique/digital par l'ajustage d'un signal digital de facon a faire correspondre un signal analogique genere a un signal analogique a mesurer.

Both components forming a binary system displaying in liquid aggregate state a range of complete miscibility and a range with a miscibility gap. Preferred parameters include an inside tubing wall surface with open pores and an outer wall surface, the degree of openings of which, calculated as fraction of open area, is reduced at least 20% in relation to the inside wall surface; open pores in the outer wall surface for the most part of a pore diameter of less than 4  mu m; tubes with a pore cavity volume of from 50-90%; tubes made of polypropylene; tubes made of glass fiber-reinforced polypropylene; tubing wall thickness of about 0.5 to 2.5 mm and outer diameter of about 2.5 to 25 mm. The tubing may be disposed within tubular-shaped sheaths of a matted web, composed of a plurality of fibers melt-spun from synthetic polymer, crossing over in places and fused together at the places of crossing. The sheaths may have a longitudinal grooved contour, and the matted web may be composed of polycaprolactam fibers with a diameter of about 0.2 to 1.5 mm. Couplings composed of the same material as the sheaths may be disposed at intersections thereof. The system is useful for the irrigation of grass, for irrigation in several layers, for permanent irrigation in arid zones, for the distribution of fertilizer, herbicides and/or pest control agents.
