Title: Gas filter element and method for leak-free connection of the pocket filter edges to a holding frame, preferably of rigid foam
Inventor: BORKENT PIETER KLAAS
IPC: B01D46/02
Filed: 1986-05-07
Abstract: The invention relates to a gas filter element, consisting of a plurality of wedge-shaped filter pockets which are each formed from fibre non-woven filter mats mutually welded together at their three peripheral edges, the remaining open filter pocket edges having been foamed as leak-free as possible with a holding frame of rigid foam, and, moreover, a stiffening profile also being foamed in in the inner space of this holding frame. The invention is based on the object of accomplishing in every case an excellent leak-free connection in the peripheral region of the holding frame which is mounted in the support grid structure. According to the invention, this object is achieved in such a way that a self-contained stiffening and also pretensioning profile continues uninterruptedly over the sides and also around each outer corner of the holding frame in order to form a stiffening profile frame, which can absorb stresses, for opening up the respective filter pocket edges between the radially directed inner wall parts of the profile and the upright matrix part which is slightly inclined to the vertical plane with respect to the holding frame, the filter pocket openings being pulled tight over the matrix part before the foaming step is started.

Title: Separation device for multilayer stacks of sheet layers
Inventor: ALBRECHT HANS DIPL ING
IPC: B65H7/02
Filed: 1986-06-11
Abstract: A separation device (1) for separating the sublayers of a multilayer stack (2) has, to register the separation point, a leaf-through apparatus (7) which leafs through the sheet layers individually in the region of one corner (14), from bottom to top, and, when it reaches the lowermost base layer associated with each sublayer and formed, for example, by a cardboard, it automatically shuts down and, by this means, first effects a lifting of the sheet layers disposed above this separating point and then an insertion of separating heads (19) into the separating point thus opened. The separating heads (19) then push the sublayer thus partially separated into a position no longer concurrent with the rest of the layer stack (2), so that the separated sublayer can be easily conveyed away as a whole. By this means, a completely fault-free separation is possible, essentially independent of the form of the intermediate sheet layers or base layers. <IMAGE>

Title: Mail letter forming from printed sheet - involves sheet cutting, adhesive strip application, folding, and perforating next to adhesive strip
Inventor: LANDEN FRANZ J
IPC: B31B70/00
Filed: 1986-08-19
Abstract: The mailing letter forming process consists of the following steps: The printed sheet is cut to the required size, i.e. the envelope format of double length or width. The sheet is then aligned in the direction transverse to its sealing flap. Adhesive is applied to the edges parallel to the direction of transport. The sheet is folded to form the envelope, and lines of perforations are formed along the adhesive strips. The direction of transport is altered through 90 deg., and a line of perforations is formed near the sealing flap. Adhesive is applied between the perforation line and the sealing flap, which is folded and sealed. ADVANTAGE - Easy and low-cost process.

Patent DE-3642232-A1 (DE)
Title: Vortex protection device and use thereof in a gas-introduction apparatus
Inventor: SCHILLER ALAN J
IPC: B01F13/00
Filed: 1986-12-10
Abstract: The invention relates to an apparatus which is designed for using suction gas-introducing means operating with propellers in such a way that it prevents the formation of vortices in the vicinity of the propeller (20) of the gas-introducing device (10) in a medium in which the propeller (20) is operated. The apparatus contains a mobile buoyant shield (30) which floats on the substance into which gas is introduced and eliminates a vortex by it being drawn into the vortex by the self-motion of the vortex and coming into contact with the vortex. The shield (30) can be movably connected to a frame (12) which also carries the gas-introducing device. Since the shield is not (directly) connected to the gas-introducing device, floats on the surface and is movable, many problems are solved which accompany designs of the prior art:     the shield (30) is simpler and cheaper to manufacture; no material can jam between the gas-introducing device (10) and the shield (30); all problems occurring in connection with the shield (30) are visible; the shield (30) prevents virtually all vortices; no vibration problems occur any longer.   <IMAGE>

Title: Electromagnetically actuated directional valve
Inventor: LEUTNER VOLKMAR DIPL ING
IPC: F16K31/06
Filed: 1987-03-13
Abstract: What is proposd is an electrohydraulic directional valve (11), the control slide (19) of which can be deflected into three positions (36, 38, 39) counter to a spring system (25) by one individual single-acting switching magnet (15). The spring system (25) has two springs (29, 32) which take effect in succession in a stroke-dependent manner and which lead to a force jump (63), assigned to a middle position (38), in the force characteristic of the spring system (25), the said force jump being intersected by the stroke/force characteristic (64) of the switching magnet (50) when a part current lower than the rated load flows through the latter. The directional valve (11) can be extended by means of a main valve (12) to form a fail-safe two-stage 4/3-switching valve (10). <IMAGE>

Title: Fuel feed system for an internal combustion engine
Inventor: KUHLEN ERNST
IPC: F02M37/00
Filed: 1987-03-19
Abstract: Fuel feed systems of this type are used for internal combustion engines fitted in motor vehicles. In these, the removal of gas bubbles from the fuel by means of a fuel vapour separator, which is generally arranged upstream of the fuel pump, is known. This arrangement, however, is not suitable for a fuel feed system under high pressure. A new fuel feed system makes use of the fuel flowing back from the internal combustion engine which has few low boiling fractions. The invention therefore proposes that the return line open into a section of the feed line situated upstream of a vapour separator and the fuel pump and that it be connected by way of a gas return line to the fuel tank, in which a non-return valve is arranged. This arrangement allows it to be used in injection systems. <IMAGE>

Abstract: The profile combination is composed of a fireproofing moulding (1) having a core (7) which foams up under the action of heat, consists of sodium silicate or the like and is encapsulated by a casing (6) which is resistant to mechanical and chemical loading and consists of rigid PVC or the like, and of an elastically deformable sealing moulding (9) which consists of silicone or the like and, with the deformation of a lip (10) jutting out beyond the plane of the fireproofing moulding (1), seals the gap between the door leaf and the door case when said door leaf is in the closed position. The fireproofing moulding (1) is arranged, and fastened to the case (2), such that a groove (12) is defined by a leg of the case (2) and a narrow side, located opposite this, of the fireproofing moulding (1), in which groove a border strip (11) of the sealing moulding (9) can be securely fixed without using any complex auxiliary means. This configuration of the profile combination makes it possible also to continue the sealing moulding (9) without interruption over the lock region of a door, said region causing the fireproofing moulding (1) to be interrupted, in order to ensure an entirely flue-gas-tight design. <IMAGE>

Patent DE-3730423-A1 (DE)
Title: Agitator
Inventor: FORSCHNER PETER DIPL ING
IPC: B01F15/00
Filed: 1987-09-10
Abstract: The invention relates to an agitator for dispersing and suspending gases and/or liquids and/or solids in liquids. The agitator is composed of an, e.g. twin-bladed, agitator propeller which is fixed to a shaft. Each blade is composed of a main blade and a leading-edge flap assigned to this. By means of the leading-edge flap, a stronger adhesion of the flow to the main blade is achieved by preforming or deflection at the leading-edge flap and, as a result, the flow resistance of the agitator propeller is considerably decreased. Moreover, greater angles of attack of the blades are possible. This leads to a considerable reduction of the space requirement and weight of the agitator and to a decrease of the energy consumption with the same processing efficiency.
