Title: Tool holder
Inventor: BAUMANN OTTO
IPC: B23Q3/12
Filed: 1986-04-16
Abstract: A tool holder with a sleeve-like basic body (9) and a bevelled recess (14) located therein for a retaining ring (13) is proposed. The retaining ring (13) is prevented from opening out radially by an overlap disc (12). The bevelling (15) serves to dismantle the retaining ring (13) after previously disassembling the overlap disc (12), compression spring (11), coupling (7), gear (5), bearing (21) and any other components. On account of the overlap by the clamping neck (3), the retaining ring (13) is not freely accessible and is therefore stripped off by the needle bearing (2) or by the dismantling disc (19). The bevelled recess (14) enables retaining rings to be dismantled even where they are not freely accessible. <IMAGE>

Patent DE-3639644-A1 (DE)
Title: Apparatus for affixing material strips to packs
Inventor: GRIEMINK BART
IPC: B65C1/02
Filed: 1986-11-20
Abstract: It has hitherto been possible to apply mechanically to packs only material strips provided with a self-adhesive coating and with a carrier paper. Non-self-adhesive material strips have hitherto been fastened to packs manually. There is to be provided an apparatus for affixing material strips to packs, which makes it possible to affix non-self-adhesive material strips at any points on the pack. This is achieved by the extraction of material strips from a magazine and the application of an adhesive or glue to the material strips (2), for example by a glue-coating nozzle (5), before the material strip (2) is affixed to the packs (12) by means of a pressure device (6) consisting of two rams (7) movable in opposition to one another perpendicularly to the transport plane of the packs (12). The application of glue can take place in a controlled manner, so that an affixation of the material strips so as to achieve a projecting length in relation to the packs (12) is also possible. The material strips can subsequently also be designed as suspension cards and be printed on on both sides. <IMAGE>
Patent DE-3642125-A1 (DE)
Title: Suction fittings for dosing pumps or the like
Inventor: RESS WOLFGANG
IPC: F04B23/02
Filed: 1986-12-10
Abstract: Suction fittings for dosing pumps for inserting in tanks have a suction head connected to the suction pipe with a magnet-operated liquid-level switch, whose float is mounted on an axial guide, and a sieve that protects the inlet of the suction head with its non-return valve. The suction fittings can be used for various operating conditions and functions, because the float with the actuating magnet has a roughly U-shaped free cross-section, and snaps onto the guide, which has a roughly V-shaped cross-section, with radial clearance. The snap-fitting makes it easy to reverse the float, so that the function of the liquid-level switch can be reversed from a normally-open to a normally-closed contact, for example. The suction head also has a minimum-sized outer cross-section, so that the fittings can be inserted into tank openings of any size.
Patent DE-3644790-A1 (DE)
Title: Rotary engine with improved control and combustion
Inventor: SCHUBERT JOHANN GOTTFRIED EMIL
IPC: F02B55/14
Filed: 1986-12-31
Abstract: For improving the combustion and for reducing the fuel consumption in the rotary engine, a piston without combustion recess is used, with as compact a combustion chamber as possible outside the trochoid. As a result, the bypass duct hitherto provided at the overlap dead centre is avoided and combustion improved by a compact combustion chamber. The absence of a bypass port avoids fresh gas losses at the overlap dead centre, whilst the compact combustion chamber outside the trochoid permits rapid combustion and better utilisation of the fuel residue at the end of the piston combustion chamber, when the latter is briefly open to the combustion chamber or to the trailing piston combustion chamber when the trailing peripheral seal brushes over the transfer port and the excess pressure of the leading piston combustion chamber scavenges the fuel to the trailing piston combustion chamber.

Patent DE-3716096-A1 (DE)
Inventor: GIES BURKHARD
IPC: G01F11/28
Filed: 1987-05-14
Abstract: A conductive liquid is dosed with a vessel having an upper rim and with a dip tube having a lower end projecting down into the vessel below the rim thereof. The vessel is periodically overfilled with the liquid such that periodically the liquid overflows the rim. Immediately after each overfilling of the vessel, the liquid is aspirated from the vessel through the dip tube until the lower end of the dip tube is above the surface of the liquid in the vessel. The resistance between the dip tube and the liquid in the vessel is continuously monitored and an error signal is generated either when the detected resistance falls below a predetermined threshold corresponding generally to that of the liquid after the overfilling but before the aspirating or when the detected resistance is substantially above the threshold after the aspirating and before the next overfilling. The flow of liquid out of the vessel is impeded except over the rim and through the dip tube at least during the aspirating step.
