Title: High density rearing system for larvae
Inventor: HUGHES PATRICK R
IPC: A01K67/033
Filed: 1993-12-09
Granted: 2000-04-25
Abstract: Method and apparatus for rearing insects is disclosed. Information concerning the physical and dietary needs of the insect as well as behavioral characteristics are utilized to maximize the number of larvae reared per unit surface area of diet and per unit of rearing area while minimizing the amount of labor and materials required. An enclosed rearing unit (1) is provided which can be located within an appropriate environment for rearing the insects. There are three sections within the rearing unit: 1) a diet space (2), 2) a larval space (3), and 3) a frass space (4). The diet space (2) includes an appropriate diet medium for the insects. The larval space (3) is located below the diet spar (2) and includes a series of vertical partitions (12) perpendicular to and in contact with or nearly in contact with the diet medium such that the insect larvae are able to disperse themselves over the partitions (12). The frass space (4) is located below the larval space (3) such that any frass collects within the frass space (4) as it is produced and does not interfere with the larval space (3) or the diet space (2). The rearing system can further include an emergence pan (30) including an outlet for allowing emerging adults to enter an oviposition cage. The emergence pan (30) replaces the frass collection pan (24) when all of the larvae have pupated. The tearing unit is turned upside down such that the emergence pan (30) is located above the larval space (3) and the diet space (2).

Abstract: A disposable liner for a pressure feed paint cup and a method for using such liner. A lid is removed from the paint cup and a disposable liner bag is inserted into the cup while an open end of the liner bag extends from the open cup end. The open liner bag end is folded over and protects the cup end and paint is poured into the liner bag. A disposable lid is placed over the open cup end and the open liner bag end is folded inwardly over the disposable lid. The paint cup lid is then attached to the paint cup, clamping the liner bag and disposable lid in place. As the paint cup lid is placed on the paint cup, a paint feed tube is pushed through anopening in the disposable lid. Optionally, a ring may be placed in a recess in the disposable lid to retain the folded liner bag end in place while the paint cup lid is attached to the paint cup. After painting, the liner and any remaining paint aredisposed of.

Abstract: Le gène INK4A (MTS1, CDKN2) code un inhibiteur spécifique (InK4a-p16) des kinases dépendantes de cycline D CDK4 et CDK6. InK4a-p16 peut empêcher ces kinases de phosphoryler la protéine du rétinoblastome (pRb) par blocage de la sortie de la phase G1 du cycle de la cellule. Les effacements et les mutations comportant le codage de InK4a-p16 par le gène INK4A, apparaissent fréquemment dans des cellules cancéreuses, ce qui implique que INK4a-p16, comme pRb, supprime la formulation de la tumeur. Cependant, une protéine totalement nouvelle (ARF-p19) apparaît en majeure partie depuis un autre cadre de lecture du gène INK4A de la souris. L'expression d'un ADNc de ARF-p19 (SEQ ID NO:1) dans les fibroblastes de rongeurs provoque l'arrêt de phase à la fois de G1 et de G2. La réutilisation économique de séquences de codage de protéines de cette façon est sans précédent dans les génomes mammifères et l'héritage unitaire de INK4a-p16 et de ARF-p19 peut refléter un double besoin des deux protéines dans la régulation du cycle cellulaire.

Abstract: An electrical line for installation in a well for transmitting power to a well pump includes a string of coiled tubing. An electrical cable having insulated electrical conductors embedded within an elastomeric jacket extends longitudinally through the interior passage of the tubing. Retainers are mounted to the electrical cable and spaced longitudinally apart from each other. An indentation is integrally formed in the tubing adjacent each of the retainers. Each indentation protrudes into the interior passage of the tubing and creates a ledge which is contacted by one of the retainers when the electrical line is installed in the well. The indentations and retainers transfer weight of the electrical cable to the tubing. Weld material is filled into the depression on the surface created by each indentation.

Abstract: A confocal microscope comprises a light source, focusing means, a detector and an encoded mask (17). The light source illuminates the mask (17) and the encoded light is then focused on a specimen. Light the from the specimen is then decoded, by either the same or a separate complementary mask, before being detected, for example by a camera. The mask (17) is encoded with a pattern which generates a combined confocal and non-confocal image and the confocal image is subsequently extracted from the combined image. This means that confocal images of different regions of the specimen can be produced simultaneously which in turn enables real-time confocal imaging of the specimen. In addition, as the microscope is no longer restricted to delta correlated images, an improvement in the light budget can also be achieved.

Abstract: A multidirectional time-division multiplexing wireless data communications system can prevent erroneous data from being transmitted through a data communications line even when a bit error has occurred in transmission data through interference, etc. occurring in a wireless area. An error correcting redundant bit, obtained by performing an error correcting code operation by an error correcting code circuit on a low-speed continuous signal, is multiplexed to a specific vacant slot in a wireless frame. A burst signal, converted by a continuous/burst signal conversion circuit through an interleaving operation, is multiplexed to a predetermined time slot, and transmitted to a wireless area. The burst signal is received by the burst/continuous signal conversion circuit, and converted into a continuous signal through a de-interleaving operation. A division circuit divides an error correcting code to generate a syndrome. Based on the syndrome, an error position detection circuit specifies bit error position in data, and an addition circuit corrects errors.
