Patent DE-3208266-A1 (DE)
Title: Attachment device
Inventor: KNOCHE ALFONS
IPC: F16B13/10
Filed: 1982-03-08
Abstract: An attachment device for a window frame or web, especially of a plastic window, comprises a sleeve-shaped expanding dowel into which a screw is inserted. The screw can be tightened by means of a mating nut which is externally conical and engages in the expanding dowel. Provided on the bottom of the screw head is a profiled recess by means of which the sleeve neck of the expanding dowel is beaded over around the edge of the hole in the window frame or web when the screw is tightened. This allows the screw head to be mounted such that it is in contact, while avoiding unacceptable stressing and deformation of the window frame or web.

Title: Laminated sheet material which is suitable for packing, protecting and securing materials or articles
Inventor: ADELMANN HERBERT
IPC: B65D65/40
Filed: 1982-03-20
Abstract: A padded packaging sheet for protection against rust and corrosion includes a coating of a volatile corrosion inhibitor on a pliable layer of a closed-cell microporous foam. The volatile corrosion inhibitor can be applied in a cohesive, non-adhering coating or directly onto the microporous layer. For the purpose of improving the effectiveness of the volatile corrosion inhibitor, the packaging sheet may include a vapour barrier, for example an aluminium foil or a film of a hydrophobic polymer, such as a silicone or polyester. A water-repellent layer may also be incorporated. The sheet may be made antistatic and/or opaque and be reinforced with fibres. A surface, for example an aircraft wing, ship's deck, house hall or vehicle bonnet or mudguard, is protected by a foam laminate which is laminated with a paper sheet or some other reinforcing protective layer and bears a layer of adhesive. Bottles can be held without dividing walls on such a foam laminate with a friction-enhancing layer on the upper side.

Title: Lifting device with at least one adhesion member, in particular a suction plate
Inventor: WAGNER HANS DIPL ING
IPC: B66C1/02
Filed: 1982-04-16
Abstract: A lifting device has at least one adhesion member, in particular a suction plate (8) which is suspended by means of at least three flexible tension members (6, 6a, 6b) on an axially movable supporting pin (19) which is under the force of a supporting spring (25). To reduce axial yielding of the supporting pin when a load is picked up by the adhesion member, to hold the adhesion member as far as possible in a horizontal position when coming down onto the load and to arrange the point of application of the lifting force on the adhesion member as far as possible in its centre, a supporting spring and a supporting pin are allocated to each tension member. Each supporting spring acts on a transfer lever (5, 5a, 5b) arranged in the radial direction. The point (29) of application of the tension member on the transfer lever lies further to the outside in the radial direction than its point (7) of application on the adhesion member. <IMAGE>

IPC: B65B27/10
Filed: 1982-10-01
Abstract: In the method, lengths of wire, in particular bicycle spokes, in a preset number in each case, and lying in the same direction, are combined to form bundles and are then wrapped, at least in the region of their mutually remote ends, with strip material consisting of stretch film which encloses said ends with limited prestress.

Title: Switching mechanism for a thermal excess-current relay
Inventor: SCHLIESSER LOTHAR
IPC: H01H37/60
Filed: 1983-03-07
Abstract: The aim of the invention is to increase the protection for electric motors against overloading, from which the object results of improving the switching mechanism in thermal excess-current relays in such a manner that high transition-point accuracy is achieved. This is intended to be achieved in that the force and movement scatters of the transition point are kept very small, a low operating force is required for the switching mechanism, and the friction forces in the system are reduced. This object is achieved by means of a switching mechanism which consists of an operating slide of two-armed construction, on whose fork ends two rockers are supported which rest with their ends, which are constructed in the form of blades, against a transmission plunger under the tension of a tension spring, which is suspended on the outer end sides of the rockers. As a result of the central arrangement of the rockers on the fork ends, an optimum solution has been found between the necessary linear movement of the system and the necessary force of the tension spring. As a result of the low spring forces, the friction losses of the switching mechanism are reduced to a minimum level, so that the parts of the changeover mechanism can also be produced from plastic moulding material. <IMAGE>

Title: Coaxial reflected-light bright-field illumination for stereomicroscopes
Inventor: WEBER KLAUS DR
IPC: G02B21/22
Filed: 1983-07-30
Abstract: The reflected-light bright-field illumination has only a single light source (4) for supplying both stereochannels (A, B). This is achieved by using polarising beam splitters (6, 8) from which the light is reflected into the observation beam paths. One component of the components which emerge from the directly illuminated, first beam splitter (6) and are separated after their polarisation is already reflected from the first beam splitter (6) into one stereochannel (B), while the second component traverses a lambda /2 plate (7) arranged in a free passage between the stereochannels (A, B), experiences there a rotation of its direction of polarisation by 90 DEG , and is subsequently completely reflected from a second polarisation-selective beam splitter (8) into the other stereochannel (A) (Fig. 1). <IMAGE>
