Title: Device for putting on stockings for physically handicapped people
Inventor: ROMMEL WERNER DR MED
IPC: A47G25/90
Filed: 1993-05-08
Abstract: The invention relates to a device for putting on stockings for people with restricted movement and in addition in particular people handicapped by having only one hand, comprising an approximately U-shaped stocking holder for fitting in the stocking. A known device for putting on stockings requires a relatively large physical effort and, in particular, handling with both hands. It is therefore unsuitable for one-handed people. The object of the invention is therefore to provide a device for putting on stockings which enables the stockings to be put on not only by people with restricted movement but also those handicapped by having only one hand. The object is solved by providing a support (1) which is located on the ground and is approximately of calf height and by the stocking holder (5) being able to be placed upon the support (1) and held on the latter. <IMAGE>
Patent DE-4316821-A1 (DE)
Title: Dental articulator
Inventor: SCHREIBER HANS DR DR
IPC: A61C11/06
Filed: 1993-05-19
Abstract: The invention presents two articulator types. By means of two guide elements (6, 7) a pure Arcon articulator on one side and a shaft (3) with eccentrically oriented fixing screw elements (4) on both sides in the maxillary arm (1) of the articulator permit simultaneous fixation and adjustment. A centrically arranged device (5) permits a defined side shift. At the same time, it is possible to integrate individual inserts (10) in the guide element (7) which virtually synchronise the motion sequence of the condylar balls (8) with that of the condyles of the patient. There is an alternative in that the guide element (11) is designed as mirror image to that of a non-Arcon articulator, in which case the Bennett angle and the inclination of the joint path can be adjusted by a knurled screw (21) as a result of the circular design of the spherical cap of the guide element (11). <IMAGE>

Title: Method and device for transferring freight units, preferably in combined road/rail freight traffic (interchangeable loader)
IPC: B65G63/02
Filed: 1993-07-07
Abstract: For decentralised transfer of heavy freight units in combined road/rail freight traffic various variants of vehicle-bound loading technology are known which are based on the side loader principle, the interchangeable frame principle and/or the displacement principle. These have the disadvantage of being too heavy themselves or not having sufficient manoeuvrability in the loading approach area of track systems and/or in the absence of the possibility of setting the load at the level of a carriageway. In order to avoid these disadvantages, an onboard loading technology which comprises a support frame which is arranged on the end sides of the road vehicle, can be displaced transversely with respect to the longitudinal axis of the vehicle and is provided with lifting columns, and which technology also comprises interchangeable running gear, and a bridge frame is provided which consists entirely or partially of the container of the freight unit and/or is a component of an enclosed logistic system. The transfer takes place by equalising the loading level in several loading stages, inserting the bridge frame into the loading track and alternately displacing the load and the bridge frame laterally with the aid of the interchangeable running gear. All the bending moments which occur during the transfer process as a result of loading are absorbed here by the bridge frame so that the onboard parts of the loading technology are only stressed by pulling forces and pressure forces. As a result, with a comparatively low deadweight of the loading technology arranged permanently on the road vehicle, a high ... Original abstract incomplete.

Patent DE-4333793-A1 (DE)
Inventor: SCHMIDER KLAUS
IPC: B65D88/10
Filed: 1993-10-04
Abstract: A container (1) for transporting and storing, in particular, flammable and non-flammable liquids which are a hazard to water in cubic tank containers and large packaging means in the form of a container has a fluid-tight bottom trough (10) which is covered by a bottom grid (15) and is provided with two closable ventilation openings which are arranged, in particular, opposite each other at the end face. The container (1) is an exchangeable container made of non-flammable material and designed in the manner of a suitcase with a centring tunnel and four supporting legs (20) which can be folded in. The bottom trough (10) has a bottom plate (11) which is profiled in the longitudinal direction. Two lateral longitudinal supports (12) and two end-face transverse supports (13) are integral constituents of the bottom trough (10). The other transverse supports (14) are arranged extending solely within the bottom trough (11) between the longitudinal supports (12) and are connected to the latter. The centring tunnel is formed by two guide profiles (16) which are spaced apart and are mounted outside the bottom trough (10). The bottom trough (10) thus formed also constitutes the bearing understructure of the container (1). This results in an extremely flat construction of the understructure, such that the dual function of storing and transporting can be implemented in an exchangeable container designed in the manner of a suitcase with a centring tunnel. <IMAGE>
Patent DE-4335416-A1 (DE)
Title: Entry area for double decker rail vehicles
Inventor: MANN MICHAEL
IPC: B61D1/06
Filed: 1993-10-18
Abstract: The present invention relates to an entry area for double decker rail vehicles which is designed in such a way that persons can enter from and alight onto the edge of the platform comfortably and safely. Double decker railways have disadvantages relating to the entry and the access to the upper deck. Thus, for example there is the problem of equalising the difference in height between the upper edge of the platform and the floor of the coach and of making a connection to the staircase to the upper deck. According to the invention a three-lane entry area is divided in its entire width in a ratio of 1/3 entry area to 2/3 entry ramp area. The resulting vehicle floor permits level connection to the bottom step of the staircase and to the utility rooms in the vehicle.

Inventor: MELTSCH HANS-JUERGEN DIPL ING
IPC: H02G15/013
Filed: 1993-11-05
Abstract: The invention relates to a sleeve with a cap, which consists of a cap body (2) and a sealing body (3, 19, 29) at the end. This sealing body (3, 19, 29) has mechanical holding devices (6) for mutual fixing of the cap body (2) and the sealing body (3, 19, 29). A sealing system is arranged independently of this, and consists of a variable volume sealing groove with a sealing ring (5). The groove volume is reduced by reducing the sealing groove volume with the aid of clamping elements (7, 23-24, 31), as a result of which the sealing ring (5) is pressed against the inner wall of the cap body (2) to produce a seal.   <IMAGE>

Title: Hand held appts. e.g. power tool with electric toroidal magnet oscillating drive
Inventor: OSTERHAGE WERNER
IPC: B24B23/00
Filed: 1994-08-25
Abstract: The appts. has a cylindrical housing with a hollow grip (1). The housing contains an electric ring magnet with a round closed construction (4) and outer coils. A magnetic counterweight (6) passes through the cross-section of the plate packet and defines a hole for the contact-free locating of the non-magnetic drive spindle (5). Compression spring guide plates (7), a helical compression spring (8) and the electronic control circuitry (2) are all integrated in the housing. The electric ring magnet is connected to an ac voltage and attracts or repels the magnetic counterweight (6) of the spindle (5) in pulses into or from the magnetic field of the closed magnet (4). The compression spring (8) thus alternately expands and compresses to continuously cause a linear oscillation of the drive spindle (5). The size of the oscillatory movement can be electronically controlled.
