Patent DE-3319970-A1 (DE)
Title: Device for regulating the flow rates in hoses
Inventor: KECK HERMANN DR
IPC: A61M39/28
Filed: 1983-06-01
Abstract: The flow rate of fluids, gases or air in hoses can be regulated using the device according to the invention. Said device consists of a U-shaped housing (7) having an inclined base (6) and a roller (1) which can move therein. By rotating the roller (1) backwards and forwards, the hose which is located in the housing (7) can be pinched together as desired from being completely open to completely closed, in order thus to regulate the flow. The shaft (2) of the roller (1) moves in the grooves (4) of the two side walls of the housing (7). At the same time, the toothed rim (9) of the shaft (2) engages in the toothed rod (5) of the grooves (4). The roller (1) can therefore move only by rotation. Displacement or sliding of the roller (1) in the grooves (4), for example caused by the pressure in the filled hose, and hence inadvertent opening of the hose gap, is not possible. This device having the toothed rim and toothed rod (5) thus ensures a constant flow rate. <IMAGE>

Title: Device for carbonisation, gasification, bio-oil production and synthesis gas production
Inventor: JANESCH RICHARD DIPL ING
IPC: C10J3/26
Filed: 1983-07-01
Abstract: The invention relates to a device for carbonisation, gasification, bio-oil production and synthesis gas production from dusty to lumpy biomass (namely harvest waste of any kind, wood waste, coal, marine algae and the like) and to a process for operating this device (Figure 1). The essential difference from the state of the respective art is the use of a sodium-cooled double-jacketed rotor with primary air feed or oxygen air feed to the reaction centre through the inner pipe; the special feature of this rotor are the ceramic discharge blades (Figure 4) fitted in the reaction centre zone. The gasification is descending, that is to say the gas generated is, after the gasification reaction, not passed through a layer of fresh biomass and thus contaminated, but fed immediately to the filtering and cooling systems. Depending on the operational mode, the reaction temperature is in the range from 600 to 1000 DEG C. The speed of rotation of the double jacketed rotor is controllable, so that the best discharge rate can be adjusted as required by means of the obliquely arranged ceramic blades (for example fast for the carbonisation process and slow for the gasification process). <IMAGE>

Patent DE-3332892-A1 (DE)
Title: Straightening and thicknessing guide for electrically operated portable planers
Inventor: FRANZLER FRANZ
IPC: B27C1/10
Filed: 1983-09-13
Abstract: To plane workpieces flat and level, the portable electric planer is provided with a height fence in the form of a bar attached transversely to the planing direction. This bar rests on two boards guided parallel to one another with the wide sides. The support for the workpiece consists of a grid lying between these boards and vertically adjustable with regard to their top edge. The vertical adjustment is made by a spindle first of all displacing the grid lengthwise. This longitudinal movement is deflected parallelogram-like into a horizontal movement via an angular guide in the lateral boards. The grid is thereby always guided in parallel with regard to the boards. The uniform thickness and planeness of the workpiece is obtained by the portable electric planer being guided across the workpiece as often as necessary until no more chips are removed due to the height fence.

Title: Fuel element for nuclear reactors, preferably for sodium-cooled fast breeder reactors
Inventor: BABIAK PETER
IPC: G21C3/33
Filed: 1983-12-10
Abstract: A fuel element for nuclear reactors, especially for sodium-cooled fast breeder reactors, having elongated fuel rods which are arranged, separated from one another by superimposed spacers, in a hollow fuel can or fuel assembly channel, this fuel assembly channel having at its lower end a bottom fitting and the so-called rod retaining plate thereabove. All the spacers of the fuel rods are fastened individually or jointly only to the inside of the fuel can, and the lower plugs of the fuel rods are clamped between the rod retaining plate and the retaining plate. The rod retaining plate and the retaining plate are joined to one another and jointly fastened to the bottom fitting. Given such a design of the fuel element, it is possible for all the fuel rods to be withdrawn at the same time from the fuel can and the spacers. In this case, the structure of the fuel element remains unchanged. Owing to the special construction of the fuel element, a substantial reduction is achieved in the time required to dismantle and repair a fuel element.

Title: Corner connectors
IPC: F16B12/14
Filed: 1984-05-18
Abstract: Corner connectors are used in furniture construction because of the simple and secure connection possibilities. To avoid a variety of types of corner connectors, the corner connector (1) according to the invention can be used for the most varied corners resulting from any types of furniture. By means of three fitting plates (2) disposed at right angles to one another and forming a corner angle, it is possible to connect virtually any corners. It is particularly simple if each fitting plate (2) has a threaded bore into which a screw can be screwed. To avoid projecting edges, a covering cap (6) provided with a clamping leg (8) is provided, which covering cap can be fixed to the inside of the fitting plate (2). In this case, it is particularly advantageous if the fitting plates are of curved construction at the free edges and the covering cap (6) is matched to this shape. The corner of a cabinet is thus filled, as a result of which cleaning is made easier. <IMAGE>

Title: Releasable rigid connection of items of furniture
Inventor: SCHROEDER GUENTER
IPC: F16B12/10
Filed: 1984-06-16
Abstract: Releasable rigid connection of items of furniture, in particular seat elements. The invention is intended to remove the disadvantages occurring when joining together or dismantling groups of furniture. Previously, a connection was produced by clamping rings, frames or fittings. The disadvantages here are the effort of assembly or the visible measures. In this case, the invention is intended to provide a remedy in that the legs of the items of furniture have a recess. Engaging in this (these) recess(es) are fitting connecting pieces which are not visible since they are concealed by the legs. In the case of legs which stand further apart, the connecting web has a U-shape and is likewise not visible to viewers standing in front or to the side of the item of furniture. By tilting the item of furniture, the leg below which the connecting piece is to be inserted is raised from the floor. The item of furniture is then placed back on the floor and the same procedure is carried out on the adjacent item of furniture. As a result, the individual items of furniture are joined together non-displaceably. The aim of easy assembly and dismantling with little effort and low cost is thus achieved.

Title: Apparatus for rolling up blanks
Inventor: HETSCH STEFAN
IPC: B01D29/00
Filed: 1984-08-31
Abstract: The invention relates to an apparatus for rolling up flat blanks until two edges of each blank have been brought together. Such blanks have hitherto had to be rolled up by hand, with simple equipment, before they could be further processed or finished in subsequent work stages. This handling procedure is laborious and inaccurate. Provision has been made, according to the invention, for grippers to be arranged on two supporting levers which can be pivoted in opposite directions from an approximately extended position, for each gripper to be movable relative to its supporting lever and for a movement control system to be provided for the grippers, by means of which system the grippers can be moved in dependence on a movement of the supporting levers and in advance relative to the latter in such a way that after a pivoting movement of each supporting lever amounting to a maximum of 90 DEG , the gripper of the said supporting lever is moved approximately through an additional 90 DEG  in the same direction, until the edges of the blank have been brought together. The apparatus is able to roll up such blanks in a fully automatic and very accurate manner.
