Title: Method for controlling the temperature of the rotors of ultracentrifuges
Inventor: BAUMERT DIETER
IPC: B04B13/00
Filed: 1986-09-08
Abstract: The invention relates to a method for controlling the temperature of the rotors of ultracentrifuges. Its aim is to shorten the temperature-control time, to reduce the energy consumption, to allow immediate centrifuging, to reduce the expenditure in terms of apparatus and to guarantee a high temperature accuracy. It was based on the object of developing a method for controlling the temperature in the centrifuge. According to the invention, it is provided that the rotor is inserted in the centrifuge; the difference between the reference temperature and the starting temperature of the rotor is formed and stored; the centrifuge drive and the heating/cooling assembly are started up, but not the vacuum generator; the temperature of the rotor surface and the temperature of the outer surface of the vessel are measured constantly and simultaneously and their difference is integrated over time; the integral thus formed is multiplied by a factor specific to the rotor; this product is constantly compared to the difference between the reference temperature and the starting temperature; and if they are the same, the centrifuge drive is switched off and the vacuum generator is started up.

Inventor: SCHEPPACH FRITZ
IPC: B23D55/06
Filed: 1987-01-21
Abstract: In a bandsaw with an endlessly revolving saw band (2) which is accommodated on at least two band wheels (3), of which one is connected to a drive motor (7) via a back-gear arrangement (8) having several output speeds, considerable ease of operation is achieved by the back-gear arrangement (8) having a transmission shaft (9) which can be driven by means of the drive motor (7) and on which a drive gear (6) in drive interaction with the driven band wheel (3) is mounted in a freely rotatable manner. By means of a locking device (13), the drive gear (6), in such a way as to be locked in terms of rotation, can alternatively be coupled to a driving element (10), connected to the transmission shaft (9) in such a way as to be locked in terms of rotation, or a further driving element (11) which, in such a way as to be locked in terms of rotation, is connected to an output gear (12), mounted in a freely rotatable manner on the transmission shaft (9), of a reduction gear unit (25) which can be driven by means of the transmission shaft (9). <IMAGE>

Title: Washing machine and washing process for the treatment of clean-room clothing in such a machine
Inventor: MINOL JUERGEN
IPC: D06F39/10
Filed: 1987-04-18
Abstract: For the cleaning and disinfection of clean-room clothing, disinfecting washing machines with washing liquor guided in circulation are used. Relatively large laundry lint can be filtered out of the circulating washing liquor by means of filtration devices.   So that even the smallest suspended particles can be removed from the washing liquor, a filter device, consisting of a very fine filter with or without a pre-filter and connected to a venting device, is used. During the washing operation, a pump (6) drawing off the washing fluid from the tub (1) is employed. The fluid is guided back into the tub (1) by way of a filter device (8) which filters lint and very small suspended particles out of the washing fluid. A venting device prevents the formation of an air cushion in the very fine filter (9). The washing machine and the washing process are suitable for the fabric-protecting treatment of clean-room clothing, the filter device (8) employed being utilised to an optimum degree. <IMAGE>

Inventor: POULALLION JEAN
IPC: A47J31/02
Filed: 1987-05-09
Abstract: Coffee filters (10) made of foldable material are usually disposable filters which must therefore be inexpensive to manufacture, require little material and be easy to handle. For this purpose, the coffee filter (10) consists of a filter bag (13) which is suspended in a drinking vessel (cup 11) and is supported on the edge (12) of the cup by support members (14, 15) which can be folded into a transverse position. The support members (14, 15) are constructed in such a way that, when they are folded into the support position, they convert the filter bag (13) at the same time into a three-dimensional, in particular polygonal shape.

Title: Process for the thermal treatment of bulk goods and apparatus for carrying out the process
Inventor: TELLER MATTHIAS DR
IPC: F26B21/02
Filed: 1987-09-19
Abstract: The process for the thermal treatment of bulk goods relates, for example, to drying, calcination, roasting or low-temperature carbonisation of bulk goods of organic or inorganic material. The reactor chamber is an elongated trough or channel. The bulk goods move through this reactor chamber from one end to the other in the longitudinal direction. In the whole reactor chamber or channel, the bulk goods particles have hot gases flowing around them, which, in transverse flow to the bulk goods moving in the longitudinal direction of the channel, are at least partially extracted over the same, de-dusted, indirectly heated via heat exchangers and optionally, in multiple circulation, again passed through the bulk goods. An example of an apparatus for carrying out the process has a semicircular trough as bottom of the channel, into which tangentially opening slit nozzles open and in which the bulk goods are additionally circulated by an agitator. <IMAGE>

Abstract: A cannula (4) is fixed to an adapter (2) and can be fixed by this adapter to a connector (16) of a cap (18) which is fixed to the open end of a sample tube (28). The adapter (2) is equipped with pawls (46) whose locking surfaces (48) engage on locking surfaces (68) of the cap (18) perpendicular to the longitudinal direction of the cannula when the adapter (2) is placed on the connector (16) in the longitudinal direction of the cannula. The locking surfaces (48, 68) can be unlocked by finger pressure, which acts perpendicular to the longitudinal direction of the cannula, on the pawls (46). It is possible in this way for various selected sample tubes (28) which have a connector (16) to be fixed to the adapter (2) of the cannula (4) without a large force being necessary for this and without rotational movements or impacts acting on the cannula (4) and thus without any movement of the cannula in a vein when the cannula remains in the vein during exchange of sample tubes. <IMAGE>

Title: Holding lens during grinding and polishing - involves thin rubber disk to create sealed-off low pressure area between lens and holder
Inventor: BRUECK ERHARD ING GRAD
IPC: B24B13/005
Filed: 1989-07-20
Abstract: The finish grinding and polishing of optical lenses requires that the lens should be securely located in a holder, preferably without the need for relocation between operations. The lens supporting side (2) of the holder (1) is lined with a rubber disk (10) having a broad outer sealing ring (3) and a narrow inner sealing ring (4). Thus an annular space (5) is formed which is completely sealed off from the surroundings and can be evacuated to create a vacuum holding the lens firmly in the holder. Specially shaped ribs (7,8) provide support to the lens at the centre and within the sealed area. The lens is lightly pressed into the holder in a low pressure chamber, thus when the holder is removed the lens is held by the sealed area. To release the lens, air under pressure is admitted through the aperture (14). USE/ADVANTAGE - Simple design. Lens is securely held for working. Holder with lens can be handled freely between operations.
