Title: Method and apparatus for producing helical edge bodies made of cemented carbide for milling tools
Inventor: TOTH LASZLO
IPC: B23P15/34
Filed: 1984-04-03
Abstract: The invention relates to a method and an apparatus for producing helical edge bodies made of cemented carbide for milling tools, the method and the apparatus having the aim of allowing helical edge bodies made of cemented carbide to be produced by machine and with a constant quality and shape irrespective of the worker. According to the invention, this is achieved by virtue of the fact that a tube of circular cross-section is pressed isostatically from a carbide dust, its diameter being larger by an amount determined by the degree of shrinkage of the cemented carbide and by the machining allowance than the diameter of the piece to be produced, measured at the edges of the shell milling cutter, that the tube is presintered, that edge bodies with the desired pitch of the direction of the turns are formed adjacent to one another from the wall of the presintered tube, in the cross-section of which bodies allowance is made for the dimensional reductions which occur during the final sintering of the edge bodies made of cemented carbide, the edge bodies formed in this way being surrounded by positively engaging devices which maintain the shape of the edge bodies during final sintering, that finally the edge bodies are brought to the desired hardness and the desired dimension by final sintering and then removed from the positively engaging devices and finish-machined.

Title: Coupling device for the automatic coupling and uncoupling of a tool, which can be deposited in a storage magazine inside the working area of an industrial robot in a defined rest position or can be removed therefrom, on the working arm of the robot
Inventor: MAREIS HANS
IPC: B25J15/04
Filed: 1984-05-04
Abstract: The invention relates to a coupling device for the automatic coupling and uncoupling of a tool, which can be deposited in a storage magazine inside the working area of an industrial robot in a defined rest position or can be removed therefrom, on the working arm of the robot. The coupling device consists of corresponding coupling halves, of which in each case one is arranged on the robot arm and the corresponding one is arranged on the tools. The mechanical coupling is effected by locking members which embrace the coupling halves pincer-like in at least two different peripheral locations. By opposed wedge-surface pairs on the coupling halves and/or on the locking members designed as a clamping claw and pivotable parallel to the parting plane of the clamping halves, force components are produced parallel to and at right angles to the parting plane, by means of which force components the coupling halves are pressed against one another and are thereby mechanically locked to one another. The design of the mechanical locking guarantees high functional reliability in a simple design and in addition rapid coupling or uncoupling of the tools.

Title: Device for the individual air-conditioning of hospital bed regions
Inventor: HILBERS HEINRICH ING GRAD
IPC: F24F1/01
Filed: 1984-05-15
Abstract: The invention relates to an air-conditioning plant which is arranged according to a rational design in the room such that individual beds can be ventilated from the head end with an air curtain. Specifically, a vertical room curtain from the injection device and in addition a horizontal air stream which comes out of the energy supply strip are used, acting simultaneously or individually. The individual air-conditioning permits the selectability of 3 ventilation stages and the switching off of the ventilation plant in bed regions. By the use of simple components which are uniform throughout the system, the investment is cost-saving. Moreover the improvement of the ventilation conditions and the stepwise switching in ventilating operation lead to a marked optimisation of energy. Further advantages are given by the simple design of the water circulation system and of the control technology. <IMAGE>

Title: Multi-layer dewatering screen, especially for the sheet-forming part of a paper machine
Inventor: ODENTHAL HEINZ DIPL PHYS DR
IPC: D21F1/00
Filed: 1984-07-13
Abstract: In a dewatering screen of this type, to increase the fabric stability of the dewatering screen which increases the screen operating time, whilst the screen top side and the screen underside can be made independent of one another and essentially without disturbing irregularities at the joining points, according to the different conditions set on the sides of the screen, provision is made for ensuring that, in the fabric layers arranged underneath the uppermost fabric layer, but at least in the lowest fabric layer of the screen, some of the longitudinal yarns and/or some of the transverse yarns of a layer are constructed as yarn bundles which have essentially the same thickness as the remaining longitudinal yarns or transverse yarns of this layer. Each yarn bundle consists of a plurality of, preferably three or more individual yarns which are not intertwisted. The joining of the fabric layers takes place in that an individual yarn of a yarn bundle is tied into at least one of the fabric layers arranged above it and is exchanged there preferably with a longitudinal or transverse yarn of the same thickness.
Patent DE-3428192-A1 (DE)
Title: Road train brake device
Inventor: DENZLER UDO
IPC: B60T8/00
Filed: 1984-07-31
Abstract: In a road train brake device (1) with a tractor vehicle (ZW) and a trailer or semitrailer (AN) a brake device is provided for each vehicle unit. According to the invention a tensile-compressive force sensor (F), for example in the form of strain gauges, is arranged on the means of connection - drawbar, fifth wheel coupling - (2, 3) between the tractor vehicle (ZW) and the trailer (AN), which sensor constantly measures the tensile or compressive force acting there as a result of a braking process and acts on a control device (A) of the brake system as actual-control variable. At the same time the actual values of a brake pressure pick-up (D) of the system and of a decelerometer (E) are fed into the control device (A). The control device (A) is programmed in such a way that as a function of the actual values received it passes control commands to brake pressure control valves (B1, B2) for the tractor vehicle (ZW) and a further brake pressure control valve (C) for the trailer vehicle (AN) so that the means of connection are free of tensile/compressive force at each braking. This results in a constant brake force adjustment between tractor and trailer vehicle over the entire speed range and, owing to the freedom from tensile/compressive force, in a neutral drive performance during brake operation. The existing brake pressure control valves (B1, B2 and C) may be connected to an ABS system. <IMAGE>

Title: Device for investigating the position and/or contour of an object by means of ultransonics
Inventor: FELDMANN WILHELM DR ING
IPC: G01S15/89
Filed: 1984-08-13
Abstract: In this device, an object identification can be carried out from amplitude and delay of the echo signals. To be able to carry out a fast and simple evaluation, four ultrasonic receivers (E1...E4) are arranged in one reference plane (X,Y coordinates) in a circle around the ultrasonic transmitter (S). Since all four echo signals must be identical with a rotationally symmetric arrangement and contour of the object (OB) in the Z axis, any differences readily provide information on the normal of the object. The invention can be used in particular in the position and contour detection of objects by means of automatic manipulating machines. <IMAGE>

Patent DE-3502372-A1 (DE)
Title: Flameproofing agent for plastics
Inventor: HERR ALFONS K
IPC: C08K13/04
Filed: 1985-01-25
Abstract: Plastics represent a considerable hazard in the event of fire, not only through their combustibility, but also through the secondary phenomena associated with the fire. These are, in particular, the smoke and fumes produced, possibly by elimination of harmful or even toxic gases, and the dripping of burning plastic material. In order to inhibit the flammability and burning behaviour, and to reduce the evolution of smoke and fumes and dripping, the invention proposes a protecting agent to be added to the plastic, formed by a mixing product of organic fibres with oxides, hydroxides, hydrogencarbonates and/or carbonates of the alkaline earth metals with phosphoric acid. Furthermore, processes are proposed for the preparation of this protecting agent by wet or dry means.
