Patent EP-0265859-A1 (EP)
Inventor: KAIMO MATTI OLAVI
IPC: E04B1/21
Filed: 1987-10-23
Abstract: The present invention relates to a device for joining together building units, comprising a lock housing (2) positioned in one building unit; a peg (3) projecting from the other building unit; and a locking means (7) by means of which the peg is locked in the lock housing and which comprises two branches (10, 11). After having passed the peg, the branches are turned towards each other by means of a guide surface (12) provided in the lock housing (2). In prior devices the locking means (7) has to be very strong because the contact surface between it and the flange of the peg is small. A large contact surface can be provided between the locking means and the flange of the peg by forming the guide surface into a continuous arched surface (12) which bends the branches sharply towards each other.

Abstract: HCMV glycoproteins B and H have been identified. The gB protein is encoded by DNA in the Hindlll F fragment of the HCMV genome lying between 1378 and 4095 bases from the F/D boundary. The gH protein is encoded by DNA in the Hindlll L fragment lying between 228 and 2456 bases from the L/D boundary. 
     The genes have been incorporated in recombinant vaccinia vectors and expressed in host animals to raise HCMV-neutralising antibody, thereby indicating vaccine potential. The glycoproteins can also be used in a variety of different ways, as vaccines or in the production, purification or detection of HCMV antibody.

Abstract: Transistors MOS dans lesquels les contacts de source et de drain (26a-b) sont isolés du substrat commun (10) et sont formés en utilisant le conducteur de porte (17b-d) pour masquer un implant (18) à haute énergie et dose élevée qui crée une mince région diélectrique (19c) dans le corps du substrat commun (10) au-dessous des régions de source et de drain (10c), mais non pas au-dessous de la région de canal (10e). Pour des substrats en silicium monocristallins, on préfère l'utilisation d'ions (18) oxygène et azote pour former la région diélectrique noyée (19c). La porte conductrice (17b-d) doit être suffisamment épaisse pour empêcher que les ions (18) oxygène ou azote implantés n'atteignent le diélectrique de porte sous-jacent (11a) ou la partie du substrat (10e) au-dessous de la porte (17b-d). Cela garantit que la porte (17d) et la région de canal (10e) du dispositif (9) ne seront pas endommagées par l'implant, ce qui autrement pourrait se produire pendant la formation des régions diélectriques noyées (19c). Des parois d'isolation diélectrique (16) sont disposées de manière avantageuse latéralement à l'extérieur des régions de source-drain (10c). Les régions de source-drain (10c) et de porte (17d) s'alignent automatiquement entre elles. On utilise généralement des doses d'oxygène d'implants correspondant à 1,7-2,2 x 1018 ions/cm2 à une énergie d'environ 150Kev pour former la couche diéletrique noyée (19c).

Abstract: Une cellule solaire (10) produit une tension électrique résultant à la fois de l'effet photovoltaïque et de l'effet thermoélectrique, lorsqu'un gradient thermique élevé est appliqué sur une cellule solaire p/n à semi-conducteurs. Pour apporter une contribution thermoélectrique importante à cette tension, la face frontale (12) de la cellule solaire (10) est chauffée à une température élevée compatible avec un fonctionnement efficace du mécanisme photovoltaïque de ladite cellule, et la face arrière (14) de la cellule (10) est refroidie à une température inférieure. On accroît l'ampleur de cette contribution thermoélectrique à la production de tension en réduisant le coefficient de conductivité thermique du matériau de la cellule solaire, en utilisant, comme électrodes de surface (24, 26) en contact avec ledit matériau, des électrodes présentant les potentiels thermoélectriques corrects, en augmentant l'intensité de la lumière et donc la quantité de chaleur introduite dans la face frontale (12) de la cellule solaire (10) et en refroidissant la face arrière (14) de cette dernière. Le matériau préféré pour la réalisation de la cellule est l'arséniure de gallium, et la cellule peut être agencée de manière à recevoir de la lumière solaire concentrée sur sa face frontale et à être refroidie sur sa face arrière par un rayonnement thermique accru.

Abstract: The soil-cultivating implement is, in particular, a plough-following drill which has an implement frame carrying the soil-cultivating tools. The implement frame is designed, via a three-point bearer (11) with a tower (11a), for the connection of the upper links and, with a transverse axle, for the connection of the lower links of a three-point linkage of a tractor. So that a plough trailer of this type can also be used as front implement, good steerability and a short construction being guaranteed at the same time, the three-point bearer (11) has a transverse axle (15, 39) which has the connection points (16a, 16b) for the lower links of the tractor. The transverse axle (15, 39) is mounted displaceably in long holes (14) on brackets (13a, 13b) attached to the implement frame (4) and is guided by two links (19, 20) which connect the transverse axle (15, 39) to the implement frame (4). <IMAGE>

Abstract: A method for sizing live fish, preferab­ly farmed fish, comprises supplying a number of fish to a lead-in basin (1) which has so low a water level that the fish is only just able to swim. The fish is permitted to follow its natural urge to seek deeper water by having a number of deeper vessels (4,5,6,7) associated with lead-in basin (1), which vessels communicate with the lead-in basin and each other at their upper edges. The deeper vessels (4,5,6,7) have an inter­mediate bottom(9,9′,10,10′,11,11′) at the same or substantially the same level as bottom (8) in lead-in basin (1). In the inter­mediate bottoms slot-shaped openings (12,13,14) with increasing width from one tank to the next are provided. Water is continuously supplied to the deeper vessels (4,5,6,7), and the flow of water is guided up through the slot-shaped openings towards lead-in basin (1) which is provided with an outlet (3). The fish will, thus, swim fram lead-in basin (1) over intermediate bottom (9,9′) in the first deeper vessel (4), and the smallest fish will be able to pass down through slot-shaped openings (12,12′) in this vessel. Larger fish will swim on above intermediate bottom (10,10′) in the second vessel where the largest size fraction but one may seek down through the slot-shaped openings (13,13′), and so on.

Abstract: A power supply circuit (2) having an operating back-up battery (7) connected to its output (1), is intended to transfer to operation entirely from the battery (7) in the event of an interruption in the mains voltage, without any significant voltage fluctuations at the consumer end, and nevertheless not to lead to the output being short- circuited when the battery (7) provides only a greatly reduced voltage at the end of its life, or is even internally short-circuited. For this purpose, the battery (7) is connected via an externally controllable path (8) to the circuit output (1) which path is controlled to conduct when the load (3) is being supplied from the mains (5) and/or from the battery (7). In contrast, this path (8) is interrupted when a voltage interruption or even an internal short- circuit occurs on the battery (7), so that at least the undisturbed operation of the load (3) can be continued from the mains (5) thereafter. <IMAGE>
