Title: Clamping ring closure
Inventor: KOTTHOFF HARTWIG
IPC: B65D45/34
Filed: 1987-02-19
Abstract: According to the invention, a clamping ring closure for containers comprises a two-armed outer lever and a connecting lever which is linked to the outer lever, the outer lever being linked to one end of the clamping ring, and the connecting lever being linked to the other end of the clamping ring. To achieve a greater pressing-on force of the clamping ring onto the container edge, the two-armed outer lever is linked to the end of the clamping ring at a point which is located outside the outer surface of the clamping ring in the radial direction of the circle defined by the clamping ring. By means of this design of the clamping lever closure, a firm connection between a lid fitted onto a container and the bead-shaped edge of a container is implemented, in particular in the region of the closure.

Title: Automatic paper drawing-in device for printers
Inventor: KOBAYASHI MASAYUKI
IPC: B41J11/42
Filed: 1987-03-20
Abstract: A method and a device are described for the automatic drawing-in of paper in a printer, in which the paper is held on the roller platen during the printing operation by a paper holder which can be raised from the roller platen for aligning the paper. To avoid an unnecessarily large unprintable top margin on the paper, when the paper holder is raised from the roller platen the paper is firstly drawn in to such an extent that its leading edge is transported beyond the contact point of the paper holder on the roller platen. When the paper holder has been lowered onto the paper and the roller platen, the paper is then transported back until its leading edge is located precisely between the paper holder and the roller platen.
Patent DE-3723091-A1 (DE)
Title: O-ring fitting gripper for industrial robots
Inventor: MERTENS PETER DIPL ING
IPC: B25J15/06
Filed: 1987-07-13
Abstract: When fitting internal O-rings, enormous difficulties have always been encountered hitherto. For instance, the very time-consuming manual fitting required considerable dexterity, and the use of fitting aids frequently lead to damage of the rings. The innovation relates to an O-ring fitting gripper for automatically fitting internal O-rings, independently of the fitting depth. The O-ring is firmly held in the negative contour of the gripping place by means of a vacuum and, since it is drawn through the fitting sleeve, it can now be compressed onto the smaller bore diameter (oval deformation of the O-ring). The fitting piston, driven via the pneumatic cylinder, pushes the O-ring, lying obliquely in the fitting sleeve, up to the fitting place, so that the O-ring snaps into the groove.

IPC: B01J47/14
Filed: 1987-09-19
Abstract: The purpose of the novel active filter unit is water treatment by means of an exchangeable ion exchanger in chemical and biological form. The active filter unit can, and is intended to be, used not only where water is supplied by the groundwater via a domestic water pump, but anywhere where it is expedient and advisable to protect the water pipes and apparatuses such as boilers, heating systems and the like from hard water and water permeated with alkaline earth metals and to avoid deposits. The use of an active filter unit further achieves the advantage of a "soft water", which is of importance, in particular, in care of the body and laundry care and also in foods and drinks (specifically tea and coffee). By means of the test stick, the water hardness (sum of alkaline earth metals) can be determined and the efficiency of an active filter unit displayed.
Patent DE-3733001-A1 (DE)
Inventor: MAIER KARL-HEINZ DR
IPC: C12P1/00
Filed: 1987-09-30
Abstract: Microbiological process for obtaining tumour-reducing substances and tumour antibodies in a test glass. Specific tumour-reducing substances are obtained by combining in a test glass a suspension of inactive tumour cells (e.g. adenocarcinoma cells) and a living reticuloendothelial system, preferably living bone-marrow. As the tumour cells present proteins foreign to the bone-marrow cells of the other living being, defence reactions take place after several days at an incubation temperature of approximately 40 DEG  C. During said reactions, tumour-specific reducing substances and tumour antibodies are produced, which may be applied as a biological drug for the treatment of tumours.

Title: Horizontal auxiliary drilling apparatus
Inventor: DRESPA GERD
IPC: B25H1/00
Filed: 1987-12-09
Abstract: The horizontal auxiliary device for drilling machines can be produced using various principles. These are, on the one hand, the principle of the guide bar which, rotatably mounted, triggers the feed and, on the other hand, the principle of the guide tube, which are pushed either externally or internally one inside the other. The feed is actuated in all cases by hand. The adhesion of the holding device to the object can be solved using an electromagnet in the case of steel or metals in general or, alternatively, using suction cups in the case of non-magnetic metals, concrete or other masonry. In all cases, the work is facilitated and energy is saved in the case of frequent drilling. Moreover, the principle of the guide tube contributes to working safety. <IMAGE>

Title: Partition system for vehicle compartments
Inventor: KRATOFIEL MATTHIAS DR
IPC: B60R21/02
Filed: 1988-01-09
Abstract: When not in use, the glass partition wall 1 resides in its slot 2 in the backrest 3 of the seat of a vehicle. When required it is raised from its slot 2, e.g. by a known electrical device, and is accommodated by lateral guide grooves 4a and b in the compartment wall and an upper guide groove 5 in the compartment ceiling. The lower edge of the glass partition remains in the slot 2, which means that the glass partition 1 is fixed on all sides. The compartment of a vehicle is thus partitioned into a front part, which constitutes the passenger compartment, and a rear part, which constitutes the luggage compartment. The throwing of objects out of the luggage compartment at the rear into the passenger compartment at the front, causing injury to the passengers, is avoided in the event of accidents or sharp braking. <IMAGE>

Title: Hammer drill with ball catch clutch
Inventor: NEUMAIER ANTON
IPC: B25D16/00
Filed: 1988-02-12
Abstract: The hammer drill has a ball catch clutch with which a predetermined torque can be transmitted from a driven hollow shaft (14) to an output shaft (6). To engage the clutch, the balls (15) are engaged in catch recesses (6b) of the output shaft (6) by a tapered area (16a) of the supporting shoulder of a setting ring (16) acted upon by a compression spring (17). When the balls (15) are disengaged as a result of an excessive torque, they pass into the effective region of an outer area (16b) lying in a plane normal to the axis of the setting ring (16) and, to avoid disadvantageous torque transmission and wear, are thus kept away from the output shaft (6) having the catch recesses (6b). To reset the balls (15) for engaging the clutch, a tapered shoulder (22a) acting on the balls (15) is provided. <IMAGE>

Title: Method and device for the production of side-fold bags (pouches)
Inventor: SENGEWALD KARL HEINZ DR
IPC: B31B155/00
Filed: 1988-09-01
Abstract: In side-fold bags (pouches) which have side folds folded inwards, the application of transverse welded seams can only be carried out in the prior art if the printing applied to the outer side of the bag is laminated with a film, since printed surfaces cannot be welded. According to the invention, the flat web (10) from which the bag is produced is intermittently pretreated in those regions (10c, 10d) which correspond to the later side folds and are provided with applied colour, so that free sections (31) in the region of the side folds are produced from the pretreatment and from the colour. These sections (31, 32) are so arranged that the transverse seams are later produced in them. In this way, a side-fold bag can be produced which has no covering film covering the printing. <IMAGE>
