  • Publication number: 20030159593
    Abstract: The invention relates to a method and a device for preparing pre-cooked meals which are supplied in a first and a second, separate component, especially pre-cooked pasta and pre-prepared sauce. Even heating is ensured by exposing at least the first component to hot steam in a closed mixing container for a set period of time, stirring and/or shaking at the same time, before or after the second component has been added. The method can be carried out fully automatically so that the finished meal only comes into contact with the person just before serving. 100 to 200 meals can be prepared per hour with the inventive device. The invention is therefore particularly suitable for preparing meals in the fast food sector.

  • Patent number: 6161244
    Abstract: The invention relates to a toothbrush (20) with a brush head which can be secured on a brush handle (24) by a bayonet catch (26). The bayonet catch comprises a locking pin (28) which is mounted in the front end of the brush handle (24) in such a way that it can be displaced axially to a limited extent but is non-rotatable and which is subject to the action of a prestressing device (50). The brush head (22) is provided with a recess (102) which has a locking groove pursuant to which the brush head (22) is mounted on the locking pin (28) by engagement of a bayonet stud (32) in the locking groove (106), the locking pin (28) being pulled out of the brush handle (24) counter to the prestressing device (50) until the bayonet stud (32) locks into a lock-in portion (114) of the locking groove.

  • Patent number: 5911712
    Abstract: A digital tampon (20) for feminine hygiene, having a round dome (33) and a recovery tape (24), consists of a blank which is shaped by winding up a length of continuous random fibre web and which is pressed to produce a preform having a fibre core, longitudinal ribs and longitudinal grooves. The longitudinal ribs are pressed weakly to the final shape of the tampon (20; 28). The preform, before being pressed to the final shape of the tampon (20), is shaped as a result of the separate, but simultaneous radial pressing of directly adjacent sectors of its entire circumferential surface to form a longitudinal groove and a longitudinal rib respectively on each sector of the circumferential surface. The longitudinal groove and longitudinal rib assigned to each sector of the circumferential surface (182) are arranged respectively in succession in the same order in the circumferential direction of the preform.

  • Patent number: 5768737
    Abstract: A toothbrush includes a brush part and a hollow handle part exhibiting an axial bearing, a coupling rod, which is slidably mounted in the axial bearing and which is connected to the brush part, a return spring, which is pretensioned on the coupling rod in the direction of the handle part opposite the brush part, and a latching device for rotationally locking the coupling end of the brush part and the coupling end of the handle part. A securing device serves to prevent axial motion of the coupling rod. A first part of the securing device is associated with the coupling rod and a second part of the securing device is associated with the handle part. The second part of the securing device is movable between a securement setting and a release setting and is pretensioned by a spring in the direction of the securement setting. An actuating device in the wall of the handle part serves to actuate the second part of the securing device.

  • Patent number: 5707166
    Abstract: The invention relates to a toothbrush (10), the brushneck (12) of which, connected to an exchangeable brushhead, is deflectably held, in a reversible, resilient manner, on a hollow handle (14) by a swivel joint (18) surrounded by a sealing element (16). The brushneck (12) is provided at its coupling end (20) facing the handle (14) with an articulated head (22). The handle exhibits at its coupling end (24) facing the brushneck (12) an articulated fork (26), between whose fork legs (28, 30) an articulated head (22) of the brushneck (12) is fitted-in and connected by a swivel axle (32). The sealing element (16) consists of a pressure-elastic material. The articulated fork (26) is itself of tension-elastic configuration, so that the sealing element (16) is held by the articulated fork (26) under elastic pre-tension between the mutually opposite coupling ends (20, 24) of the handle (14) and of the brushneck (12).

  • Patent number: 5564152
    Abstract: The invention relates to a toothbrush (20), the brush head (22) of which can be removed from a brush handle (24). A threaded pin (26) can be moved to a limited extent out of the brush handle (24), counter to the action of a prestressing spring (32), when the brush head (22) is screwed onto the pin, until a stop catch (36) of the brush head (22) engages in a recess (38) of the brush handle (24) and locks the brush head in the rotational direction, while the prestressing spring (32) holds the brush head (22) under prestress against the brush handle (24). A firm connection can thus be established simply and rapidly between the brush handle and the brush head, irrespective of the shape of these parts.

  • Patent number: 5377830
    Abstract: Brushhead magazine for receiving a number of brushheads (22), comprising a plurality of containers, which lie parallel alongside one another in mutual separation, in each case fully enclose a brushhead (22) and the height of which is dimensioned to correspond approximately to the width of a brush base (26) of each brushhead (22), a coupling end of the brushheads (22) in each case facing towards the container opening (30). A wall exhibits, in the area of each container opening (30), a closing flap (32) made from dimensionally stable material, which closing flap is defined by a target rupture line (36) and a hinge (40), formed by an attenuation line (38). The closing flap (32), as its target rupture line (36) is destroyed, can be pivoted by means of the coupling end of a brush handle about the hinge (40) into an open position in the interior of the assigned container. In each container there is disposed a locking device, by means of which the closing flap (32) can be locked in its open position.

  • Patent number: 5301821
    Abstract: In the case of a holder for a toothbrush, which holder comprises a plate (1) to be attached to a wall and a holding element (7) extending, in the usage position, perpendicular to the plate, the plate (1) and the holding element (7) are pivotably connected to each other and there is provided, moreover, on the plate (1), a suspension device (3), in which a magazine (10) containing accessories for the toothbrush can be suspended. When the holding element (7) is pivoted out of the open position into the usage position, the holding element (7) grips over the suspension device (3) in such a way that the magazine (10) is protected against unintended detachment from the holder.

  • Patent number: 4969298
    Abstract: In order that bar-shaped cutters can be ground as accurately as possible, it is essential that the bar-shaped cutters are clamped as close as possible to the surfaces which are to be ground. For this purpose, each bar-shaped cutter is pressed against two stop faces or surfaces by means of two claws of a clamping lever, and the one claw which is closer to the surface to be ground is structured to be more elastic or resilient than the other claw. Particularly, the claw closer to the surface which is to be ground is more intensely pressed or forced against the bar-shaped cutter than the other claw.

  • Patent number: 4397251
    Abstract: A control device comprising a housing having a bottom pin, and a cable drum mounted on said bottom pin said cable drum being stressed by a reset spring 11. The cable drum 6 is radially and axially guided, at its periphery, by offset supporting rollers (1c). A regulating member 8a of a potentiometer 8 is fixedly installed on the hub 6a of the cable drum 6. The tap pins 8b of the potentiometer 8 are arranged on the slide 9 axially movable in the hub. The slide 9 is connected with a treadle 3 by a tappet 10 provided with a ball-and-socket joint 9b, 10a. The treadle 3 is mounted to the housing 1 to be vertically pivotable by means of two pivots beside the cable drum 6. The blocking means for the cable drum 6, actuatable by remote control, is located between the two pivots. The device of the present invention is especially suited for the control of electrical household sewing machines.
