Title: Device for coating flat dough products
Inventor: FREDERICKSEN GUNTER
IPC: A21C5/04
Filed: 1989-10-13
Abstract: The coating of dough products with a coating material which is difficult to handle has hitherto required a manual treatment which was always inaccurate, sometimes unhygienic as well and in all cases expensive too. In order to avoid this, a device is proposed according to the invention which permits the dough products which are to be coated to be coated continuously in a volumetric feed and over an accurate area even with the most difficult coating material. <IMAGE>

Abstract: A ventilator, adapted to be mounted in a window or door, and comprising a housing provided with an air inlet window situated at the outer side of said housing, and, in particular, being shielded against rain, and with an air outflow window situated at the inner side of said housing. According to the invention the air inlet window comprises a downwardly directed passage (7) in the outer housing portion (6), in which passage a hinged vane (9) with a horizontal hinge axis (10) is arranged, said vane being adapted to move between a lower and substantially horizontal position and an upper inclined position, which positions are determined by stops (11, 15), the wall (13) of said passage co-operating with the edge (12) of said vane which is opposed to the hinge axis being curved in such a manner that said wall (13) is situated at a distance from said vane edge when the vane (9) is in its lower position, so as to maintain a residual air passage (14), and when said vane (9) is moving towards the upper position, said passage (14) will be gradually reduced.

IPC: H04N7/30
Filed: 1989-04-27
Abstract: In a television transmission system for digital picture signals each picture is partitioned into sub-pictures of NixN 2  pixels for limiting the bit rate. Each sub-picture is subjected to a forward picture transform for generating basic picture weighting factors. To this end each sub-picture is multiplied by a reference picture which has different values for different pixels (for example, as described by a Gauss function). This multiplied sub-picture is subsequently multiplied by a number of kernel pictures so that the said basic picture weighting factors are obtained. Each kernel picture is equal to the product of the reference picture and a basic picture. Of the collection of basic pictures each basic picture is an orthogonal polynomial associated with the square value of the reference picture. For regaining the original sub-pictures each weighting factor is multiplied by the original kernel picture from which the weighting factor is obtained. Each weighting factor of a sub-picture thus supplies an auxiliary sub-picture. Summation of all auxiliary sub-pictures yields a replica of the original sub-picture.

The apparatus further comprises a signal source (3) for supplying a first and a second tracking signal (f₁, f₂) which are applied to the head halves (K₁ and K₂ respectively) of the write head for simultaneously recording the first and the second tracking signal, respectively in the first and the second track half of a track, in such a way that during the recording of consecutive tracks on a record carrier the first and the second tracking signals are recorded only in every n-th track (Figs. 1 and 2a), n being an integer greater than 1 and preferably equal to 2. An apparatus for reproducing the electric signal recorded by means of said apparatus is also described. The crosstalk of the first and the second tracking signal detected during reading is utilized for the purpose of tracking.

Patent EP-0381706-A1 (EP)
Title: A method of maintaining a desired recombinant gene in a genetic population of cells.
Inventor: CURTISS RAY III
IPC: C12N15/68
Filed: 1988-10-06
Abstract: The invention encompasses methods of maintaining desired recombinant genes in a genetic population of cells expressing the recombinant gene. The methods utilize mutant cells which are characterized by a lack of a functioning native gene encoding an enzyme which is essential for cell survival, wherein this enzyme catalyzes a step in the biosynthesis of an essential cell wall structural component and the presence of a first recombinant gene encoding an enzyme which is a functional replacement for the native enzyme, wherein the first recombinant gene cannot replace the defective chromosomal gene. The first recombinant gene is structurally linked to a second recombinant gene encoding a desired product. Loss of the first recombinant gene causes the cells to lyse when the cells are in an environment where a product due to the expression of the first recombinant gene is absent. The invention also encompasses methods of creating and isolating mutant cells with the above characteristics. The cells of the invention are useful for commercial production of desired products, for components of vaccines for immunizing individuals, and for release into the environment.

Abstract: On peut prolonger de manière considérable la vie utile d'un élément de batterie électrolytique couramment utilisée dans les chaînes en série (17) comme source de puissance de réserve, en maintenant la polarisation des plaques positives (22) d'un tel élément à un niveau prédéterminé par rapport à une électrode de référence (26) de composition similaire qui est en contact avec l'électrolyte de l'élément. Pendant l'alimentation de l'élément en tension de charge flottante habituelle, un circuit de commande (20) détecte toute variation de la polarisation qui tombe en dessous du niveau voulu et fournit en quantité mesurée un courant d'entrée de faible intensité aux plaques positives, ce qui a pour effet d'élever la polarisation de manière correspondante pendant un laps de temps considérable. La modification progressive de la polarisation entraîne une passivation de la surface des plaques, qui bloque la pénétration de l'oxygène au niveau du métal des plaques et empêche la formation croissante et fortement destructive d'oxyde de métal.

Abstract: A process for assembling flat structures by means of heat-activable adhesive foil is characterised in that the adhesive foil (4) is subjected to a preactivation before its processing involving the required heat activation. This makes use of the finding that, by preactivation, the adhesive bonding temperature required during subsequent processing can be reduced considerably, without at the same time reducing the quality of the adhesive bond. This allows a significant increase in the application possibilities of such adhesive foils, which were limited by the restricted thermal endurance of at least one of the flat structures to be assembled. <IMAGE>
