In linear actuators, where the spindle device (6) is driven via a toothed gearing comprising two bevel gears (10, 12), it proves difficult to maintain a satisfactory greasing of the two gears. The grease is "cut" off the gears relatively soon. The solution to this problem is to completely contain the gears inside their respective, separate chambers between tightly limiting surfaces, at least at the gear rim area, such that the grease be retained in this area and be forcibly applied on the gear rim to effect the greasing.

Jusqu'à présent, le choix des pâtes à tartiner végétales a été très limité car, à de rares exceptions, seules les substances à fruits secs compacts sont produites afin d'être utilisées comme tranches minces ou comme pâte végétale différente, c'est-à-dire une substance sous forme de gelée découpable ou en tranches incorporant des légumes et/ou des fruits finement hachés comme substance de base. La substance peut être produite à partir de matières premières fraîches ou congelées qui, au moyen d'un procédé mécanique, sont finement hachées jusqu'à une taille de 4 à 8 mm. On ajoute à ladite substance 0,5 à 2 % de gélatine, par exemple la gélose, après quoi elle est pasteurisée à 70 à 80° puis refroidie afin qu'elle prenne la forme d'un bloc découpable.

Support ou séparateur, surtout un serre-livres comportant une partie élastique (1) et un élément de maintien (2). Le support ou le séparateur est caractérisé par le fait que la branche (5) de la partie élastique, qui prend appui sur la partie inférieure de l'étagère et la branche supérieure (3) sur laquelle se glisse l'élément de maintien est de forme conique. De cette manière le support ou le séparateur peut être adapté à l'épaisseur de l'étagère par un déplacement de l'élément de maintien sur l'élément élastique. Ceci permet d'obtenir une pression superficielle entre lesdites parties de sorte que le support se bloque. Les deux orifices de l'élément de maintien sont ainsi situés de sorte que le renversement de l'élément de maintien permet d'obtenir des variations en fonction de l'épaisseur double de l'étagère.

Linear dual actuator for lying or sitting furniture having at least two sections (2,3), which with one end is rotatably embedded in the article of furniture and where each section (2,3) with an arm (5,7) secured to a pivot shaft (4,6) can be adjusted. The dual actuator comprises a housing (8) with a recess (10) in each end for each of the pivot shafts (4,6) on the article of furniture and where the arms (5,7) on the pivot shafts (4,6) after the dual actuator has been mounted on the article of furniture reach into the housing (8). Each end of the housing is furnished with a drive comprising an electric motor (11), which through a transmission (12) drives a spindle (13a) with a thrust element (18) having one end in engagement with the arm (5,7) for adjusting the sections (2,3). The electric motors (11) are located axis-aligned with the respective spindles (13a). Thus, the housing (8) can be constructed as a flat box with a relatively low height, as the only thing which should be considered in terms of the height is the thickness of the electric motors and not their length. As the housing (8) can be constructed as a flat box without bulges and indentations the mould is thus also relatively uncomplicated.

Linear dual actuator for lying or sitting furniture having at least two sections (2,3), which with one end is rotatably embedded in the article of furniture and where each section (2,3) with an arm (5,7) secured to a pivot shaft (4,6) can be adjusted by means of the linear dual actuator. The dual actuator comprises a housing (8) with a drive at each end, which comprises an electric motor (11), which through a transmission (12) is in driving connection with a spindle (13). On the spindle (13) is arranged an activation element (14) with a spindle nut in engagement with the spindle (13), where the activation element (14) can be brought into engagement with the arm (5,7) for adjusting the sections (2,3). In case of power failure there is the problem that the back rest and leg rest section cannot be lowered to a plane level, which can make the bed uncomfortable or completely impossible to sleep in. This problem is solved in that a rotating element in the drives comprises a connection (21), which is accessible from the outer side of the housing (8) for connecting a tool, e.g. an Allen key (22) for driving the respective drives for the back rest and leg rest section (2,3) for lowering of these to a horizontal position.

Linear actuator comprising a housing (1) with an electric motor (6), which through a transmission (12) drives a spindle (10) with a spindle nut (13). To the spindle nut (13) is secured a tubular adjustment element (3), which is guided in a guide tube (2). A bushing (15) is secured at the rear end of the guide tube (2) by means of which the guide tube (2) is secured to the chassis (7) of the actuator. Expediently, the securing is done with stampings (16) from the outer side of the mounting bushing (15) and into the guide tube (2). These stampings (16) are appropriately done opposite channels, such as screw channels (17) in the guide tube (2), such that the stampings (16) are received in the channels and moreover do not in a disrupting manner protrude into the guide tube (2) and prevent the movement of the spindle nut (13) and the adjustment element (3), respectively.
