Patent DE-3701598-A1 (DE)
Title: Cassette receptacle
Inventor: REIN ULRICH DIPL ING
IPC: G11B23/023
Filed: 1987-01-21
Abstract: The drawers (5) of a cassette receptacle have resilient tongues (12, 13) which are prestressed towards the outside and engage in each case with a wrap-around (14, 15) over a cassette (16) placed in the drawer (5). When the drawer (5) is disengaged, it moves out of a housing (4) of the cassette receptacle. The resilient tongues (12, 13) thus also move partially out of the housing (4) and can move outwards due to their prestress. This leads to the wrap-arounds (14, 15) releasing the cassette (16). <IMAGE>

Title: Heavy-current switch
Inventor: BRAUN DIETER DIPL ING DR
IPC: H01H33/14
Filed: 1987-02-23
Abstract: This heavy-current switch (1) has at least one vacuum switching chamber (6) and at least one current path (2), which is enclosed by non-magnetic metal encapsulation (16), per phase. The vacuum switching chamber (6) has an interruption point which is acted on by an axial magnetic field. It is intended to create a heavy-current switch (1) whose vacuum switching chambers (6) are acted on by current only briefly during switching-on and switching-off processes. This is achieved in that the current path (2) is divided into at least one power current path (4) and into a rated current path (3) which is parallel thereto. The vacuum switching chamber (6) is arranged in the at least one power current path (4), but its interruption point is not opened until the current which is to be disconnected has been commutated from the rated current path (3) to the power current path (4). <IMAGE>

Abstract: A dispenser for the delivery of dosed quantities of a pasty substance comprises a receptacle having a push button mounted on the receptacle for movement upwardly and downwardly adjacent an end thereof. A rod extends through the receptacle and is connected at its inner end to a follower plunger. A substance flow tube has one end extending into the receptacle to the reservoir thereof for the pasty substance and an opposite end with a substance delivery orifice which extends out of the receptacle. A closing wall adjacent the tube closes the delivery orifice. The follower plunger is in sliding engagement with interior of the receptacle and it is movably engageable around the rod and is movable along the rod upon discharge of a substance through the delivery orifice. There is a connection between the plunger and at least one of the closing wall and the substance flow tube for shifting one end of the closing wall relative to the flow tube opening the delivery orifice for the delivery of the substance therethrough. The delivery plunger normally moves up the rod member during the dispensing movement effected by movement of the plunger manually. This contributes to the outflow of the pasty substance through the delivery tube and out through the orifice.

Title: Method for operating a production line in the manufacture of individual slide fasteners
IPC: A44B19/42
Filed: 1987-04-11
Abstract: A method for operating a production line in the manufacture of individual slide fasteners from a continuous chain of slide fasteners consisting of a plurality of slide-fastener sections. The production line has at least two production machines having their own drives, the first machine operating with a lower cycle number than the second. The chain of slide fasteners is guided from the first production machine to the second. The first production machine is operated without interruption and the chain of slide fasteners is counted out into a buffer after the first production machine until there is a preselected number n of slide-fastener sections in the buffer. When the buffer has been filled, the second production machine is switched on. The second production machine is switched off again if the tension of the chain of slide fasteners exceeds a preselected threshold value ahead of this production machine, and so it continues periodically with the second production machine being switched on again when the buffer has been filled again. <IMAGE>

Patent DE-3720622-A1 (DE)
Inventor: HAPPLE KARL DIPL ING
IPC: B65G53/24
Filed: 1987-06-23
Abstract: In an interlinked conveying or processing system, for example a silo installation, the articles must be conveyed from a starting point to a destination point. For this purpose, the units to be switched onto a transport path must be calculated and the corresponding branch points must be switched for switching through the transport path. For determining a transport path, a sequence list in which are contained all the units and branch points with their connections is fed to a program processor. The program processor simulates different states of the branch points. When the desired destination point is determined, the transport path is stored in a switching list which contains the switching states required for the activation of the transport path. The switching list is at the same time used for controlling the installation during operation.
Patent DE-3720699-A1 (DE)
Title: Support (base, stand, pedestal) for illuminating bodies
Inventor: ILLGUTH GUSTAV
IPC: F21V21/06
Filed: 1987-06-23
Abstract: From the Patent Application P 3603152.6-33, a support is known for illuminating bodies which has a tunnel-type undercrossing passage which is intended for the purpose of bringing publications, illustrations (books), atlases and similar information media closer to the light source and thus better utilising the illuminating power of this light source. The idea of this invention can be implemented:   a) as mobile support, suitable for "upgrading (retrofitting)" lamps/luminaires,   b) as component in lamps/luminaries.   The practical application of the idea of this invention is impaired by the negative impression which a hollow body with one or two big holes can cause in a sophisticated living environment with people who have a sense of aesthetics. In order to avoid this aesthetically negative effect, it is proposed according to the invention to cover the feed opening and the dispensing opening of this undercrossing passage by removable closure pieces such as tiles and the like or by curtains which give way and have a pattern which in conjunction with the lamp and/or the support meets aesthetic requirements. These closure pieces - tiles, curtains, little flags - can be painted, embroidered or decorated otherwise. In this way, the homely impression of lamp and support can be maintained if the undercrossing passage is not in use, even with lamps/luminaires of high artistic value. If necessary, however, the possibility can easily be created, ... Original abstract incomplete.

Patent DE-3733132-A1 (DE)
Title: Circuit arrangement for acoustic compensation of the ambient noise in the case of headphone (earphone) reception
Inventor: BEHRENS MICHAEL DIPL ING
IPC: H04R3/00
Filed: 1987-10-01
Abstract: In known circuit arrangements for acoustic compensation of the ambient noise in the case of headphone reception, the ambient noise is picked up by means of a reference microphone arranged outside the headphones and connected to an interference-compensating filter. The negated filter output signal is superimposed in a loudspeaker on the useful signal, as a result of which it is possible to undertake a partial compensation of the ambient noise at the ear. Since the noise at the ear is generally not available for setting the interference-compensating filter, it has to be assumed that the acoustic transmission conditions are constant. Furthermore, the reduction in interference which can be achieved is limited, inter alia, by the relatively poor coherence between the microphone signal and ambient noise at the ear. A novel arrangement of the reference microphone inside the headphone on the one hand supplies a very good coherence, while on the other hand the microphone signal can be used as error signal for setting the interference-compensating filter. The undesired feedback of the loudspeaker signal is prevented in this case by means of a further compensation filter.
