Title: Adjustable hospital bed
Inventor: KOETTER HELMUT
IPC: A61G7/015
Filed: 1986-06-03
Abstract: The hospital bed has a multi-part, adjustable mattress frame comprising a top frame part (101) and a central frame part (102) and a thigh support (103) mounted in a support frame of a bedstead. The top frame part (101) and the thigh support (103) are pivotable and are connected to one another so as to be couplable by force transmission means for this pivoting movement. The central frame part (102) is firmly mounted in the support frame (100) and the top frame part (101) and the thigh support (103) are each mounted in the support frame (100) so as to be pivotable about a swivelling axis (104, 105) located in the vicinity of the central frame part (102). The top frame part (101) has an actuation lever (108) which interacts non-positively with a lever arm (111), fastened on the thigh support, in the adjustment of the top frame part after having passed through a dead movement path for the simultaneous pivoting of the thigh support (103). A force transmitter (116), preferably a gas pressure spring, is arranged between the support frame (100) and the lever arm (111) of the thigh support (103), for further pivoting of the thigh support (103) independently of the top frame part (101). <IMAGE>

Title: Method for producing a pressure-tight electrical cable (line, lead) connection and a cable connection produced in accordance with this method
Inventor: LUHMER HORST DR
IPC: H01R13/533
Filed: 1986-07-02
Abstract: The invention relates to a method for producing a pressure-tight electrical cable connection and a cable connection produced in accordance with this method from an internal space which is subject to pressure to an outer space at a lower pressure. Previous sealing difficulties resulting from inadequate strength of plastic sheaths, excessively large space requirements of O-ring seals or "sweating" of ceramic parts are countered according to the invention in that the electrical cable is passed through a bushing in a component consisting of an aluminium alloy, which component, after the bushing has been fitted, is subjected to surface treatment in the form of oxidation to produce an insulating layer which is similar to ceramic, the bare cable subsequently being passed through the bushing essentially without play and then being sealed.

Title: Mounting process for roof segments
Inventor: DENNERT HEINZ
IPC: E04B7/24
Filed: 1986-07-22
Abstract: The invention relates to a process for on-site final mounting of a roof segment (1) which is intended for a ridged roof and is prefabricated from two sloping roof elements (2) connected together by means of a ridge hinge (4). The roof segments (1) are transported to the building site with their sloping roof elements (2) in a mutually parallel position. At the building site, they are raised up by means of a hoist, spread out and positioned on the building. The invention is characterised by the following process steps: the hoist acts on the roof segment (1) in the region of the ridge hinge (4) such that the raised-up sloping roof elements (2) hang vertically essentially in the mutually parallel position. The roof segment (1) is lifted over a mounting surface. Subsequently, the roof segment (1) is lowered, its sloping roof elements (2) being positioned on the mounting surface and, by further lowering, the eaves edges (18) thereof being supported in a rolling manner on the mounting surface, said elements being spread apart into their spread-out position. After reaching the desired spread-out angle (24), the latter is fixed by fitting a tie beam (25) between opposite rafters (6) of the two sloping roof elements (2). The roof segment (1) which is fixed in this manner is positioned on the body (30) of the building. <IMAGE>

Patent DE-3638534-A1 (DE)
Inventor: HAHNE JOCHEN
IPC: B61H15/00
Filed: 1986-11-11
Abstract: The largely automatic adjustment of the brake rods of brake devices, especially shoe brakes for rail vehicles, is generally achieved by means of single-acting or double-acting brake slack adjusters at the beginning of the corresponding brake gear chain. With longer brake gear chains, re-adjustment can no longer be compensated for by the brake slack adjuster alone and the positions of the brake levers at the end of the chain may become so incorrect that adequate functioning of the brake device is no longer guaranteed. So that additional manual adjustment of the brake gear can be largely dispensed with and the efficiency of the brake device improved, on a brake device of this type at least one additional brake slack adjuster is fitted in series in the brake gear chain after a double-acting brake slack adjuster. The necessary adjustment travel for the respectively preceeding brake slack adjuster is determined by the sum of the necessary degrees of play in the associated friction pairings to be acted upon and the required adjustment travel to be established comparably in any succeeding brake slack adjuster. <IMAGE>

Title: Hand Atlas with Air Rescue Plan
Inventor: UMBACH WOLFGANG
IPC: G09B29/00
Filed: 1987-05-23
Abstract: A hand atlas consisting of maps on the customary scale is supplemented by one or more special sheets of transparent material on which the individual symbols and individual information relating to life-saving services are marked so that, when the special transparent sheet is laid on the conventional map, they make it possible to identify immediately and easily where, for example, hospitals, police stations or helicopter stations are situated. The additional provision of the respective telephone numbers thus makes it easily possible for those involved in the accident to call the particular required form of assistance immediately and in the shortest possible way. It is further conceivable to arrange on these special sheets other additional special information in order thus to improve the information content of the actual map. Expediently, the radio beacons are also shown on the special sheet or sheets, so that the pilot of a rescue helicopter can easily identify and rapidly fly to the target area. <IMAGE>

Title: Process for producing vessels from plastic sheet and vessels produced according to the process
Inventor: REIFENHAEUSER HANS
IPC: B29C51/14
Filed: 1987-10-06
Abstract: Process for producing vessels from plastic sheet, in particular for packaging foodstuffs. A thermoformable, thermoplastic composite plastic sheet with a layer of PVDC which is crystalline in the use state is subjected to a thermoforming operation at a predetermined temperature. The composite sheet, however, is first heated to a temperature above the crystallisation point of the PVDC. By this means, the crystallisation of the PVDC is cancelled or its degree of crystallisation is reduced by at least 50%. Then the composite sheet is quenched to a temperature of less than 75@C, preferably less than 50@C. The thermoforming operation is carried out directly after the quenching. A significant improvement in the mechanical strength and stability of the vessel is obtained without impairing the diffusion resistance of the PVDC coating.

Title: Method for comparing the magnitude of a torque with a reference value, applications of the method and device for applying the method
Inventor: RUFER DIETER ALEX
IPC: G01M13/04
Filed: 1987-12-18
Abstract: The method and the device are provided for comparing the torque necessary to turn a mechanical element, for example the inner part of a ball-bearing, with a reference value. A permanent-magnetic body is connected to the element to be turned, permanently or only temporarily. By means of stationary magnetic coils, a device generates a rotating magnetic field of variable strength, which works like a drive on the permanent-magnetic body. This arrangement has a maximum transferable torque, which is equal to the reference value and results from the strength of the magnetic field and the magnetic properties of the permanent-magnetic body. If the rotatable element to be examined has the ability to follow the driving magnetic field, the result is that the reference value is at least as large as the torque needed to turn the element. A useful application is quality control. By means of simple observation of the rotating state (turning - not turning), the free-running specimens can be differentiated from the stiff specimens. The application of the method enables iterative torque measurement in conjunction with systematic alteration of the reference value.

Title: Swinging holder for reflectors for measurements with electrooptical tacheometers
Inventor: BOHNENSTINGL KLAUS
IPC: G01C15/02
Filed: 1988-02-17
Abstract: For marking out and sighting of a sight rail with electrooptical tacheometers, up till now the points to be measured were held manually with a reflector on the sight rail by the measuring assistant and set vertical during the entire measurement procedure by visual observation. The new swinging holder is intended to exclude uncertainties and sources of error of the manual holding, to allow itself to be set directly on the sight rail board and also on a nail already driven in and to set itself vertical by means of gravity. Any point can be held directly on the sight rail board (2) by means of a point (3) which is attached under the reflector carrier (4). In order to measure to a nail already driven in, a sleeve (8) is fitted over the point (3). The reflector carrier (4) is fixed firmly to a bow (1) which acts as a pendulum and is so designed in terms of weight that it sets the swinging holder vertical by means of gravity.   The swinging holder is suitable for all sight rail surveys which are carried out with electrooptical tacheometers. <IMAGE>
