Patent DE-3416015-A1 (DE)
Title: Film and slide projection system
Inventor: DASZINNIES GUENTER
IPC: G03B21/10
Filed: 1984-04-30
Abstract: In order to render universally applicable a film and slide projection system having a plurality of projectors which can be operated against a common projection surface simultaneously or in a mutually alternating fashion, selectively insertable polarisers are arranged between the lenses of at least two projectors and the projection surface. It is therefore possible in conjunction with two interconnected projectors optionally to present for viewing a stereo image which is viewed by means of polarisation spectacles, or else it is also possible to achieve additional projection effects by folding out or drawing out one or both polarisation filters. Dissolves, multi- vision effects or motions are thus possible in a flowing, and also two- as well as three-dimensional fashion.
Patent DE-3416088-A1 (DE)
Title: Convertible fashion jewellery, such as buttons, buckles and the like
Inventor: FICKERT GOTTFRIED
IPC: A44C13/00
Filed: 1984-04-30
Abstract: The current fashion jewellery, such as brooches and pins, is harmful to clothing since the materials are pierced by pinning it on. A change is desirable; variety is highlighted by the patent. Even name tags (for example at fairs) which are worn on suits either pierce the material or are lost. An attached name tag is unsuitable. Of course it is possible to make changes to the arrangements shown without deviating from the concept of the invention. Magnetic attachment is sufficient for inexpensive jewellery.

Patent DE-3422280-A1 (DE)
Title: Magnetic force amplifier
Inventor: TUEFFERS LOTHAR J
IPC: H02K53/00
Filed: 1984-06-15
Abstract: A plurality of magnets which are arranged and polarised in a suitable manner with respect to one another are moved with respect to one another. Some of the magnets are located on a rotating frame while others are fixed outside the rotating frame, to be precise in each case in pairs such that the magnets on the rotating frame are moved through between those outside the rotating frame. In consequence, the outer magnets are moved up and down by attraction and repulsion of the rotating-frame magnets. In this case, more force can be extracted from the outer magnets than is required for rotation of the rotating frame.

Title: Method for cutting off a short-circuit current having no zero crossings
Inventor: BALZER GERD DR
IPC: H01H9/56
Filed: 1985-06-07
Abstract: In the case of cutting off short-circuits in high-voltage systems, rather than, as in the past, proceeding from a fixed tripping time, which is calculated on the assumption of unfavourable conditions, for a power circuit breaker, the invention proposes that an individual tripping time (t3) be calculated in each case of a short-circuit which occurs at a time (t0) and is identified at a time (t1). For this purpose, it is proposed to sample the current behaviour (I) in an initial region (10) until a time (t2) and, using the data obtained from this, to adapt a mathematical model which is used for calculating the predicted theoretical time (t5) of the first zero crossing of an uninfluenced short-circuit current (8). Starting from the theoretical time (t5), the tripping time (t3) is calculated, taking into account the response time of the circuit breaker itself and any other influences. The actual first zero crossing occurs at a time (t4) which, if the tripping time (t3) is selected suitably, is before the theoretical time (t5). <IMAGE>
