Abstract: In a sliding-lifting roof or top sliding-lifting roof for automobiles, comprising a sliding lid slidably guided on lateral guide rails and pivotal upwards by means of driven rear guide shoes for ventilation, the outward pivoting and inward pivoting take placethrough specially constructed guide blocks, fixed to the sliding lid, which cooperate with the rear guide shoes not only by guide slits but also by control levers. In this way, in the interests of an improved stability of the lid, the outward pivoting and inward pivoting movements of the sliding lid are divided into two movement phases, which are created, on the one hand, by the engagement, which can be cancelled, of guide pins with the guide slits in the guide blocks and, on the other hand, by the control levers, articulated to the rear guide shoes and connected rotatably and displaceably to the guide blocks.

Title: Gene manipulation and expression using genomic elements
Inventor: SHERWIN STEPHEN
IPC: C07K14/535
Filed: 1992-05-05
Abstract: Expression of mammalian target genes is achieved by employing chromosomal target DNA, either native primary cells or YACs in a yeast host, where the YACs include a fragment of a mammalian chromosome, the fragment comprising the target gene. Employing homologous recombination, an amplifiable gene is integrated into the mammalian fragment at a site to allow for amplification. In the same step, or one or more steps, as desired, the mammalian gene and/or the transcriptional system may be modified by in vivo mutagenesis. The resulting construct from homologous recombination may then be transformed into a mammalian expression host and integrated into the host genome, either randomly or by homologous recombination. The amplifiable gene may then be amplified by an appropriate agent providing for multiple copies of the.target gene and the expression host grown to provide for high yields of the desired wild-type or modified protein.

Abstract: Magnetic cartography process and apparatus.      According to the invention, measurements are performed by means of mag-netic field sensors placed in "fish" (10) moved in the area to be mapped, gradients are determined on the basis of the difference between the meas-urements supplied by two sensors at the same time, this applying to any pair of sensors, and/or on the basis of the difference between the meas-urements supplied by the same sensor at two different times, this applying to any sensor, which leads to at least one map of gradients which is broken down into a map of regional field gradients and a map of local field gradients. On the basis of the latter, a determination takes place of the geological field relative to the area, or the gradients of said field and then the local field, by adding the geological field to the regional field determined on the basis of its gradients by an inversion and direct calcu-lation method.

Patent CA-2116808-A1 (CA)
Inventor: SOTER TIMOTHY A
IPC: H01F27/26
Filed: 1994-03-02
Abstract: ABSTRACT       A dry type transformer has an iron core, high voltage windings embedded in cast resin, and low voltage windings resin encapsulated. The iron core is manufactured with stacked core steel. After the core is stacked,instead of using banding straps, a heat shrinkable material is wrapped around the core legs and is heated to enable the shrunken material to apply uniform compression over the core legs. This will facilitate coil loading, reduces audible core noise and reduce core losses. In place of shrink wrappable material, a film material with elastic properties could be used.

Title: Exhaust box
Inventor: MARCELLO DOMINIC
IPC: F24F13/10
Filed: 1994-05-03
Abstract: An improved exhaust box used to ventilate rooms or devices within a building to the ambient environment, is disclosed. The exhaust box has a generally rectangular main body portion, with an exterior end and an interior end and is adapted for installation in the wall structure of the building. An inlet portion projects from the interior end and is adapted to receive an exhaust ductin sealed relation thereto. A flange portion extending radially outwardly from the exterior end of the main body portion helps retain the exhaust box in place within the wall structure. The main body portion has a bottom portion that is sloped downwardly towards the exterior end so as to cause water to flow towards the exterior thereof. A damper member is pivotally attached to the exhaust box so as to be gravity biased into place against a receiving surface atthe interior end of the inlet portion. The damper member allows exhaust air to flow through the inlet portion, to thereby be exhausted to the exterior of the wall structure, and also causes the inlet portion to be closed off when no exhaust air is flowing therethrough. A removably attachable rain screen grill, which precludes the entry of rain into the exhaust box, extends outwardly from the exterior end of the main body portion. The bottom of the rain screen grill is trough shaped and has perforations therein so as to allow for drainage of water therefrom.
