Abstract: Machine d'empaquetage par film rétractable (60) confectionnant par unité de temps deux fois plus de paquets que les machines usuelles. La machine comprend une paire d'éléments de scellage et de coupe (61, 63, 65, 67). Les deux éléments (61, 63, 65, 67) sont précédés d'un capteur (78, 80). Le premier élément de scellage et de coupe (61, 63) est actionné lorsqu'on détecte le bord de fuite de paquets numérotés pairs (16); le deuxième élément de scellage et de coupe (65, 67) est actionné lorsque le deuxième capteur (80) détecte le bord de fuite de paquets numérotés impairs (16). Les paquets (16) sont par conséquent emballés par deux lorsqu'ils quittent le premier poste de scellage et de coupe (62) et sont emballés individuellement lorsqu'ils quittent le deuxième poste de scellage et de coupe (64). La bande transporteuse (30) qui transporte les paquets (16) à travers la machine (6) défile à une vitesse environ deux fois plus rapide que celle des machines de la technique antérieure, alors que les éléments de scellage et de coupe (61, 63, 65, 67) de la machine ci-décrite (60) fonctionnent à la même cadence que les machines de la technique antérieure.

Abstract: The reflector, manufactured from brittle plastic, is inserted in a receptacle (4). The connection between the reflector (1) and the receptacle (4) consists of a first connecting part (5) inserted into the receptacle (4) and a second connecting part (6) which consists of plastic and rests flat against a wide side face of the wall part (2) of the reflector (1) and overlaps with this wall part. The overlapping sections (10, 11) have overlapping openings into which a sheath (16), consisting of elastic material with a bolt-shaped mounting part (17) penetrating it, is inserted. The bolt-shaped mounting part (17) presses the sheath (16) axially together with such a force and/or widens the opening of the sheath (16) at least in certain sections with such a force that the sheath (16) rests with its cover surface against the side faces of the overlapping openings (12, 13, 24) and with its inner face against the bolt-shaped mounting part (17), with pretensioning. …<IMAGE>…

Abstract: The present invention relates to a stereoscopic image apparatus for calculating the position and the height of the stereoscopic model taken on a stereoscopic pair by viewing the stereoscopic pair three-dimensionally, and more particularly to a stereoscopic image apparatus wherein even when stereoscopic pairs different in size are used, the imaging distance can be kept constant, and the operability of the adjustment of the interval between a pair of marker sections is improved. 
     In the present invention, the lines of observation sights from stereoscopic photos are reflected by first mirrors, and the lines of observation sights reflected by the first mirrors are led by second mirrors into imaging lens sections where a stereoscopic image is formed. The first mirrors can be moved generally along parabolas whose focuses are located in the positions where the second mirrors are placed, so that the imaging distance can be kept constant at all times. 
     In the present invention, marker sections are arranged in the direction in which a pair of imaging lens sections are arranged, and since, along with the rotation of a handle that is rotated about an axis parallel with the optical axis of the imaging optical system, the marker sections can be moved away from each other or closer together by the same distance, the moving operation of said markers can be effected by the handle orthogonal to the direction of the movement of the markers.

Abstract: A totally enclosed electric motor which is effectively cooled by means of an internal ventilation system and an external ventilation system. The internal ventilation system includes an internal fan (30) driven by the rotor which forces internal ventilating air into and along an annular series of longitudinal internal ducts arranged adjacent to the internal cylindrical wall supporting the stator. The internal ventilating air leaving the internal ducts enters a brush compartment where the air is directed axially over the commutator and through the stator-rotor arrangement and back to the internal fan. The external ventilation system includes an external fan (34) driven by the rotor which forces external ventilating air from the atmosphere into and along an annular series of longitudinal external ducts (90) arranged radially outwardly from the series of internal ducts and into exhaust compartments at the far axial end of the motor.

Abstract: A tunnel kiln, including a preheating zone, a firing zone, and a cooling zone comprises a top wall (12) and a pair of opposite side walls (13), which define a tunnel. At least at the firing zone, the top wall or roof (12) and each of the side walls (13) are formed by a pair of oppositely arranged inner and outer shells (16,17), which are mutually spaced substantially in their full extent. A plurality of burners (28) are mounted in each of the side walls (13) and the firing zone, and combustion air is supplied to each of the burners through a combustion air inlet (33), which communicates with a space (22) defined between the inner and outer shells (20,21). Because the combustion air supplied to the burners flows through the space defined between the top and side walls, a substantial part of the heat loss through the top and side walls of the kiln may be regained and used for preheating the incoming fresh combustion air without contaminating the same by combustion gases.

Inventor: MALEK LAWRENCE T
IPC: C12Q1/68
Filed: 1990-08-23
Abstract: This invention relates to an improved process for amplifying a specific nucleic acid sequence. The process involves synthesizing single-stranded RNA, single-stranded DNA and Double-stranded DNA. The single-stranded RNA is a first template for a first primer, the single-stranded DNA is a second template for a second primer, and the double stranded DNA is a third template for synthesis of a plurality of copies of the first template. A sequence of the first primer or the second primer is complementary to a sequence of the specific nucleic acid and a sequence of the first primer or the second primer is homologous to a sequence of the specific nucleic acid. The improvement of the amplification process involves the addition of DMSO alone or in combination with BSA, which improves the specificity and efficiency of the amplification. The amplification process may be used to increase the quantity of a specific nucleic acid sequence to allow detection, or to increase the purity of a specific nucleic acid sequence as a substitute for conventional cloning methodology.
