Patent DE-3321587-A1 (DE)
Title: Tool for expanding pipe ends
Inventor: SCHWALM DIETER
IPC: B21D39/20
Filed: 1983-06-15
Abstract: This tool is designed as a portable tool for expanding pipe ends on metal pipes, in particular for preparing pipe ends for pipe connections. Mounted on a clamping head (1) are two two-armed pivot levers (29), on which clamping jaws (32) are arranged limitedly axially movably for grasping the pipe end. The clamping head (1) is located on a handle shaft (2) which at the same time forms the cylinder housing for a piston (5) which can be moved by a pressure medium and which at its free end bears an expanding mandrel (20) which can be pressed into the pipe end. With the movement of the piston (5), a pressing of the pivot levers (29) and thus of the clamping jaws (32) against the pipe is brought about automatically via control surfaces (41) and pressure rollers (39) on the pivot levers (29). The clamping jaws (32) are guided on rear inclined surfaces in such a manner that, on a movement in the direction of the expanding mandrel (20), they move away radially from the pipe end (24). On pressing the expanding mandrel (20) into the pipe end, this guiding of the clamping jaws (32) brings about an increase of the clamping force and on the return movement contributes to releasing the bracing. For expanding pipe ends made of easily deformable metals such as aluminium, copper or the like, an expanding mandrel (20) made of hard plastic is expediently used, which renders the application of a lubricant superfluous. <IMAGE>

Title: Device for transporting pallets, for example, using a chain drive
Inventor: WITTIG KARL-HEINZ DR ING
IPC: B23Q7/14
Filed: 1984-02-28
Abstract: Device for transporting pallets, for example, using a chain drive. The device can be used for the linear transport of piece goods along an aligned track. The aim of the invention is to considerably extend the conveying path of a carrier, which is attached to the endless conveying chain of conventional design, of a chain drive. The object of the invention is to produce a device for transporting pallets, for example, using a chain drive, in which at least one carrier is attached to an endless conveying chain, the upper and lower runs of which are bounded by two chain wheels, the chain with the chain wheels and the chain wheels themselves moving in space. This is achieved by mounting deflection chain wheels not in a stationary fashion, but at both ends of a carriage, which is movable on a track in both directions of its ends, as a chain drive wheel is mounted in a stationary fashion underneath the track, the lower run being guided via the said chain drive wheel and it being possible optionally to couple the carriage either to one of its deflection chain wheels or fixedly to the frame. <IMAGE>

Title: Method and device for the failsafe representation of a mimic diagram on a screen
Inventor: SCHWARZWAELDER JOERG DIPL ING
IPC: G06F11/16
Filed: 1984-03-24
Abstract: A method for the failsafe representation of a mimic diagram on a data display device (M) is specified, in which the image data supplied to the data display device are continuously checked by the fact that a test code is formed by data reduction from the image data stream and this code is compared with a reference code previously stored and characteristic of the mimic diagram to be displayed. The reference code is formed by modulo-2 addition from a basic code representing the static picture elements and the change codes corresponding to the individual mimic diagram changes. Provision of the reference code saves a second separate image data channel and a second feedback-type shift register for data reduction in devices for carrying out the method according to the invention. When a colour monitor is used as a data display device, the latter applies to each of the three primary colours. <IMAGE>

Patent DE-3430582-A1 (DE)
Inventor: DAHM GEB VERGES
IPC: A45D40/26
Filed: 1984-08-20
Abstract: The device described (2) for applying cosmetic materials comprises a shell (1) inside which is arranged a column of cosmetic material which can be raised by a lifting device. The ejection end of the shell is closed with a top portion (4) which carries an applicator material (7) on at least one part of its surface for receiving and subsequent application of the cosmetic material, and possesses outlet openings (5' and 5'') for the outlet of the cosmetic material from the shell to the applicator material. This ensures that the cosmetic material reaches the applicator material in a dosable quantity when the raising mechanism is actuated and stays there, available for subsequent application. The applicator material can be an overlay which covers totally or partially the top portion and consists of a penetrable fibre material or foam for the cosmetic material, but also of a pack of flock material or of brush hairs which covers partly or totally the top portion. The outer contour of the applicator material is determined by the outer contour of the top portion and possesses preferably both slightly-curved to flat-surface regions, as well as regions with imprinted points or edges. In this way the cosmetic material can be applied with the same device or without additional accessories, either flat or in lines, without the outer contour changing during its use. The device is suitable for all types of cosmetic materials i.e. both for hard materials (e.g. eyebrow pencils) and for pasty-waxlike materials (e.g. lipsticks) and for creamy-soft materials (e.g. rouge, eye shadow). The position, size and form of the outlet openings in the top section can be adapted to the relevant requirement; for hard materials, however, care must be taken that the largest radial distance to the outlet openings from the axis of the shell is not smaller than the radius of the column of cosmetic material. Furthermore, it is advantageous that the inner edges of the outlet openings for hard materials are designed in the form of scrapers.

Title: Double bed or sofa whose lying height and seat height are identical
Inventor: FOERSTER ARTHUR
IPC: A47C17/16
Filed: 1984-10-08
Abstract: Setting out from the dimensions of a sofa as seating furniture, by means of the invention the seat height is retained even in the case of the lying surface as a bed. Mounted on interconnected boxes is a seat surface which, together with the boxes, results in the seat height. The seat height thus resulting is utilised by the invention in such a way that backrests extend down to the bottom of the support boxes and thus make surfaces available which can be used as a lying surface. By using a plurality of rear surfaces lying one after the other, this useful surface is doubled. Therefore, two backrests result which lie one behind the other in a sofa, and two extensions on the rear surfaces down to the ground and a seat surface result in a lying surface which corresponds to the dimensions of a double bed. By pivotably arranged surfaces on the backrests and pivotably mounted armrests on the seat surface, the dimension of the lying surface is also possible in the second direction. A lying surface is produced which can be used with the head position in two directions. <IMAGE>
