Title: Coffee machine with a centrifugal filter
Inventor: LEUSCHNER UDO
IPC: A47J31/22
Filed: 1981-09-22
Abstract: The invention relates to a coffee machine with a centrifugal filter which takes up the infusion water by means of a corotating conveying device arranged thereon from a heated water bowl arranged underneath the conveying device, the bottom of the water bowl being passed through by a pipe projection rising inside the water bowl and an electric motor being arranged under the water bowl and acting on a drive shaft which projects upwards through the pipe projection and drives the centrifugal filter. In this connection, the aim is to be achieved of alleviating the problem of imbalances and in particular of bringing about good centring of the centrifugal filter. This aim is achieved according to the invention in that there is connected to an upper end section of the drive shaft (16) in a rotationally fixed manner a carrier (25) for the operationally detachable coupling of the centrifugal filter (22), which projects downwards, with a slightly conically widening carrier jacket, beyond the pipe projection (14) of the water bowl (8) as far as the bottom region of the water bowl (8). As a result, with relatively low overall construction height of the device, high centring arrangements are made possible for the centrifugal filter. <IMAGE>

Title: Air-cushion transport for heavy sheet-like loads
Inventor: FRAAS ALFRED DIPL ING
IPC: B65G7/06
Filed: 1982-02-06
Abstract: The invention relates to the movement of heavy sheet-like loads on an air-cushion, without appreciably varying the total dimensions or shape of the transport unit, that is to say not by the use of a vehicle with its own air supply or the like, on which the load rests. The design provides a combination of an air-cushion vehicle and an air table, the functioning of the air table being capable of acting from above or from below. The essential features are   1) that the air-cushion is generated from a combination of an air table and air-cushion pallet; 2) that the compressed air is supplied within the bottom, the bottom at the same time constituting the running surface; 3) the two all-round sealing rings on the underside of the transport pallet form an inner and an outer pressure chamber, in order to bridge interruptions in the bottom; 4) that the air-cushion pallet as the load-bearing part possesses only a relatively thin plate and the carrying force is uniformly distributed by the air pressure to the load to be transported.   <IMAGE>

Title: Method and device for checking coded coins
Inventor: RUDOLPH GUENTHER DIPL PHYS DR
IPC: G06K7/08
Filed: 1982-03-03
Abstract: The invention relates to a method of checking coins or banknotes which have a coding consisting of small soft-magnetic particles in a common metallic base material, and to a device for carrying out the method. Methods and devices which are known for similar purposes in each case check the sum effect of the entire coin and are not suitable for decoding. Even a further development of the known method and device would not achieve the object since, in this case, interfering influences would become so severely noticeable that an unambiguous identification of the soft-magnetic particles in the coin would not be guaranteed. According to the idea of the invention, the coin is rotated about its major axis between a permanent magnet and an induction coil which is tuned to the size of the soft-magnetic particles, the flux changes caused by the soft-magnetic particles in the magnetic field being converted into voltage pulses, which are compared with a "pattern" and are used to initiate a switching process. In the cross-section through the checking device according to Figure 3, the magnet (5) and the induction coil (6) opposite it can be seen, between which the coin (8) is rotated about its major axis by means of the friction wheel (4). <IMAGE>

Title: Method and device for decoring castings
Inventor: FEDERHEN BERND
IPC: B22D29/00
Filed: 1982-10-23
Abstract: A method and a device for decoring castings, in particular for removing a sand core from castings subjected to little thermal stress, by the knocking action of hammer-like members are intended to make possible rapid decoring even of complicated castings while causing little stress due to the decoring operation. This is achieved by the fact that, during a short period of action of the blows on the casting, natural frequencies are produced and the core is ground up and expelled by vibratory movements of the entire casting. The device for this purpose is distinguished by a vibratably mounted machine frame (3) containing the hammer-like members (5) and having a vibrator (25) and a mount (17, 18), connected to this vibrator, for the casting (30). The hammer-like members (5) should be pneumatic hammers projecting approximately horizontally from the machine frame (3), their striking heads (8) determining a movement area for the casting (30). <IMAGE>

Title: Method of placing solid packing in mining operations in steep stratification and devices for carrying out the method
Inventor: SCHIGULSKI HANS DIPL ING
IPC: E21F15/00
Filed: 1982-11-25
Abstract: The invention relates to a method and a device for placing solid packing when working steeply sloping seams, with the use of a packing wall whose wall sections can be shifted individually one after the other from the bottom to the top. In order to suppress greater flowing movements of the packing masses placed in the packing space, the packing material is fed via a drop-pipe line from the working face into the waste areas, which open during the shifting of the wall sections behind their waste lagging. The drop-pipe line is formed by aligned conveying channels of the individual wall sections. The latter conveniently also have platforms which project into the waste space, are loaded by the packing and help to steady the packing masses placed in the waste space.

Title: Solar heat exchanging accumulator for transferring heat from solar collectors into a container filled with water
Inventor: HOLZNER JOSEF
IPC: F24D11/00
Filed: 1983-11-17
Abstract: The invention improves the known devices for transferring heat from solar collector heating systems, heat pumps and boiler heating systems by means of a flowable heat transporting medium into a container which is mostly filled with water (irrespective of the capacity of the container as an accumulator) in such a way that it is possible to tap service water via the heat extraction circuit without the need for prior heating of the entire accumulator volume to the required or desired temperature. Further advantages are:   1. The possibility of adaptation to any heating system (without having to take limitations of volume into account). 2. The exchangeability of almost all parts into parts having other material characteristics, as the case may be. 3. The rapid reaction time of the described system, especially directed to solar collectors, is therefore capable of being used the more effectively for other heating systems. 4. The far reaching lack of susceptibility to damage during transport and installation, owing to flexible design of the entire concept. 5. The combination of the 2 media accelerators in the solar heat exchanging accumulator ensures trouble free recirculation in the entire solar installation system without further incorporation of recirculating pumps.

Title: Electrical contact switch having a spring-operated mechanism
Inventor: HERL WERNER
IPC: H01H5/06
Filed: 1983-11-25
Abstract: An electrical switch having a spring-operated mechansim for operating an electrical contact (3) which is mounted on a moving contact element (4), rests on a stationary contact (1) with a specific contact pressure in a first stable position, and is isolated from the stationary contact (1) in a second stable position. A torque is exerted on the moving contact switching element (4) by means of a tension spring (11) in both positions, in a respectively alternating direction. The changeover from the one position to the other in each case takes place by the movement of the second spring end, which is mounted on an operating element (26), in the direction opposite to the torque beyond a dead-point position, after which a springing switching movement occurs. In order to avoid the contact pressure gradually reducing to zero at the dead-point position, a restraining surface (37), which projects into the movement path of the tension spring (11) and can be overcome by the tension spring (11) in its pivoting movement only after an increased spring tension once the movement has already passed the dead-point position, is arranged between the two ends of the tension spring (11). <IMAGE>
