Title: Method and device for driving a rotary machine
Inventor: ALDRIDGE DENNIS RAYMOND
IPC: F01K21/00
Filed: 1981-05-02
Abstract: An excess of air exceeding the combustion air required by a furnace, for example a reformer furnace is compressed by at least one compressor device and then heated by exchange of heat with hot, gaseous products of combustion from the combustion part of the furnace and a first and a second flow of heated compressed air are formed. The first flow of air, which has a higher temperature than the second flow of air, supplies the combustion air for the furnace and is expanded in a first turbine, which is coupled to the or to a first compressor. The second flow of air (that is the excess air exceeding the combustion air demand of the furnace) is superheated by the combustion of additional fuel in the flow and if necessary steam is also injected into the flow before it is expanded in a second turbine, which is coupled to a machine to be driven, for example a synthesis gas compressor and to the or to a second compressor device.

Title: Floating seal for double-belt presses
Inventor: FIEDLER EWALD
IPC: B30B5/06
Filed: 1981-07-08
Abstract: The invention describes a floating seal for double-belt presses, in the case of which the material to be pressed, which is required to produce pressed chipboards, for example, is inserted between two endlessly circulating belts, which can be respectively loaded on their sides facing away from one another by pressure plates which are provided with pressure chambers and with a floating seal which circulates in guide grooves, for pressure-sealed application onto the belts. The longitudinal sides, which extend in the running direction of the belt, of these floating seals are made of a hard sealing substance and the transverse sides are made of a soft sealing substance. A floating seal of this type is characterised by a high level of operational reliability and durability, unevennesses in the belts being compensated by the soft transverse seals, while the friction forces occurring in the running direction of the belts are taken in by the longitudinal seals, without expensive supporting or holding structures for the seals being necessary.

Patent DE-3138800-A1 (DE)
Title: Backwashable water filter
Inventor: WALTER ECKARD ING GRAD
IPC: B01D29/00
Filed: 1981-09-30
Abstract: The backwashable water filter is intended for the plumbing in buildings. It has two cylindrical filter surfaces. The filtered water is collected in the intermediate annular space and is passed to the clean water outlet. This intermediate space is furnished with reinforcing ribs, so that the filter surfaces cannot be pressed together. The unpurified water enters the filter via the multiple path tap. In the normal position of the tap, the water is passed over both filter surfaces (Figure 2). By turning the tap by about 60 DEG to the right (Figure 4), the outer filter surface is backwashed, while the inner surface remains in operation and vice versa. The tap plug with upper part and the inlet connection bend can be exchanged with each other, so that the filter can be used in a left-handed and right-handed configuration. The tangential tube sections on the housing base and the guide surfaces on the filter fabric supports produce a spin during the backwashing, which increases the cleaning action. <IMAGE>

Title: Advance column for strengthening a shaft lining, in particular of a tubbing column
Inventor: RUDERSDORF FRIEDEMANN A DIPL I
IPC: E21D5/11
Filed: 1981-11-07
Abstract: The invention deals with an advance column (1) for strengthening a shaft lining, in particular of a tubbing column (2), in a sunk shaft. This advance column (1) consists of precast reinforced-concrete segments (3) which form precast rings placed one on top of the other and have vertical joints (4) and horizontal joints (5) between the precast segments (3). In order to counteract compressive strain, dragging and bending of the shaft tubes, the horizontal joints (5), with compensation plates (8) in between, are bridged by means of steel sealing rings (9, 10, 11) anchored in the precast segments (3) and form on the inside of the column an encircling annular groove (13) filled with joint mortar (12). A steel sealing shell can consequently be dispensed with if the vertical joints (4) are also filled by means of a joint mortar (12). <IMAGE>

Title: Storage device for bundles of stacked bags to be fed to a filling apparatus
Inventor: MITTELBACH HELMUT
IPC: B65G65/00
Filed: 1981-12-29
Abstract: To allow continuous operation of an apparatus for filling bags, the latter is preceeded by a storage device, serving as a buffer, for holding a multiplicity of bundles of bags, which must have a compact structure in combination with a high storage capacity. The storage device according to the invention is formed from a multiplicity of vertically displaceable pallet-like support plates which are connected movably to one another, to which support plates bundles of bags are supplied and from which the said bundles are removed by means of a horizontally displaceable bundle slide which lies in the region of the common supply and discharge level of the support plates. Each support plate is provided with a central penetration in which the bundle slides, which are formed from pneumatic cylinders, can be displaced for the purpose of transporting the bundles. To supply the storage device, the individual support plates are moved successively into the supply level and are supplied from the side. To remove bundles of bags, the support plates are moved successively into the discharge level corresponding to the supply level. By means of the bundle slide, the bundles are then ejected at the side opposite to the supply point. <IMAGE>

Title: Winding machine for the winding and/or unwinding of material guided in web form
Inventor: KOSLOWSKI GERHARD
IPC: D02H13/00
Filed: 1982-04-08
Abstract: The side stands (2, 3) are connected to one another by means of steel bearers (5, 6). An intermediate stand (7) is mounted displaceably on the steel bearers (5, 6). A combined beam-receiving and -rotating device (9) is arranged on one side stand (2). The intermediate stand (7) carries a beam-receiving device (10). A self-locking mechanical feed device (11) is arranged between the other side stand (3) and the intermediate stand (7). The feed device (11) is connected to a feed-force generator (14) which can be set to continuous operation. A beam lifting-out device (21) can be arranged under the winding beam (8). This ensures by simple means that the clamping force is maintained during the winding, but that, in the event of a failure of the clamping force, a harmful loosening of the winding beam preventing further winding operations does not occur. Further measures allow the winding beam (8) to be lifted out and introduced by means of the feed-force generator (14). <IMAGE>

Title: Method and device for developing electrostatic charge images
Inventor: LANGE GOTTFRIED DIPL PHYS
IPC: G03G15/08
Filed: 1982-04-08
Abstract: The invention relates to a method and a device for developing electrostatic charge images, the charging of the pigment, its transport to the charge image and the application of the pigment to said image being performed at spatially separate locations. In this regard, it is difficult when using a dry toner to achieve proportional development of the charge image. The invention provides that the toner powder is transported on an electrically insulating belt (11), whose rear is provided with electrically conductive strips (16) located transverse to the transport direction (11'), to the image layer (21) and is transferred there by an electric field onto the image layer (21). In addition, for the purpose of precipitating undesired particles (8, 9) before transport the pigment can be led through a chamber (10), which acts as an air classifier, if necessary around an electric field (7). The proportional development of charge images according to the invention is particularly suitable for use in medical diagnostic radiography. <IMAGE>

Patent DE-3228918-A1 (DE)
Title: Permutation cylinder lock with flat key
Inventor: SPERBER ALFRED
IPC: E05B19/18
Filed: 1982-08-03
Abstract: The invention relates to a permutation cylinder lock with a flat key, of which the web, during insertion into the lock, displaces the locking elements or tumblers (16) of the lock from the blocking position into the open position. The key web consists of individual segments (13) of equal width which are lined up in succession on the key shank (5) and which form web teeth. The segments (13) are releasably arranged on the key shank (5) of the flat key divided in the longitudinal direction and are held positively and/or non-positively (for example, clamping between the shank halves, attachment onto projections of the key shank, insertion into grooves of the key shank). As a result of their releasable arrangement, the segments (13) are exchangeable or adjustable, as desired, and can be adapted to a particular key secret. If the user changes the key secret of the lock, the key web of the flat key can therefore also be changed correspondingly. There is no need to produce and keep in stock a multiplicity of differently designed flat keys; the user can compose an appropriate flat key at any time when he knows the key secret, this being especially advantageous if a key is lost. <IMAGE>

Patent DE-3243610-A1 (DE)
Inventor: HOFFMANN HANS DR
IPC: G04G15/00
Filed: 1982-11-25
Abstract: When programming a radio and/or television receiver for future transmissions, problems may occur due to overlapping of the programmed transmissions. For this purpose the individually programmed transmissions are provided with priority data which control the sequence in the event of overlapping transmissions. In the same way given transmissions can also be provided with blocking data which block the reception or reproduction, respectively, thereof. The use of the priority data is particularly efficient when the transmissions are controlled in addition or exclusively by transmitted identification numbers and consequently are only received during the actual transmission time, as then shifts with respect to the planned transmission times cannot be foreseen. Additional possibilities are derived from the storage of data characterizing the type of the transmission, when these data are transmitted simultaneously with the relevant transmission.
