Patent DE-3123296-A1 (DE)
Title: Electrical power supply rail
IPC: H01R25/14
Filed: 1981-06-12
Abstract: Electrical power supply rails (busbars) having a rolled-profile rail body consisting of sheet steel have an essentially C-shaped cross-section. Two profiled limbs are in each case connected on the longitudinal sides to the profile base, on whose two longitudinal sides facing away from the profiled base profiled flanges originate which extend towards one another parallel to the profiled base, are in opposite directions to one another and between them bound an insertion slot in an adapter retention channel. In the rail cavity, the profiled flanges retain between themselves and the profiled base an insulating material profile (section) having electrical conductors. An end piece or coupling piece, which is inserted in the rail longitudinal direction, is held at least in the region of an end face of the electrical power supply rail. Stresses in the steel plate structure, which are possibly caused during the rolling process, cause the rail body to gape apart at the ends. The invention has essentially overcome the difficulties associated with this in that it provides (on each profile flange) retaining limbs with inner surfaces which point away from the adapter retention channel. A fork tine of a retaining fork which has two tines and is assigned to the end piece or coupling piece presses against each inner surface.

Title: Method for working and cultivating arable soil in a number of superposed layers
Inventor: WEICHEL ERNST
IPC: A01B49/02
Filed: 1981-07-02
Abstract: In a method for conservative working or cultivating of arable soils, it is assumed that such soils are generally present in a three-layer form, i.e. on a deep-lying, strong soil horizon there is already a layer of earth which is loosened to a greater or lesser extent and has a relatively good crumb structure, and on the soil surface there is a layer in a good tilth state. The method according to the invention relates to the identical or different working of one or at least a second of these soil layers, with adaptation to the different crumb structure already existing, and without a mixing of the individual layers with one another.

Title: Apparatus for the filling of valve bags
Inventor: WANS THEO
IPC: B65B61/28
Filed: 1981-07-08
Abstract: The invention relates to an apparatus for the filling of valve bags (7) above a conveying means for the filled bags, said device comprising a filling pipe and, arranged underneath this, a swing-out bottom support. Apart from a low space requirement, the invention is based on the object of making it possible to fill bags of different sizes, of bringing these bags into a palletisable or stackable form and of positioning them in a highly accurate manner on the discharge belt irrespective of their centre of gravity. For this purpose, the invention provides that the bottom support comprises two rotatable plates (8, 9) which are arranged in mirror-image fashion with respect to the vertical longitudinal centre-plane through the filling pipe and which can be pivoted on two pins (10, 11), which are parallel to the filling pipe, from a vertical position to a horizontal, or approximately horizontal, position, and vice versa, and the pivot pins (10, 11) are arranged at a distance from the one longitudinal edges of the plates (8, 9) and from one another in such a way that these longitudinal edges are closer together when the plates (8, 9) are in the horizontal position. <IMAGE>

Title: Wave-power generator
Inventor: BSCHORR OSKAR DIPL ING DR RER
IPC: F03B13/18
Filed: 1981-08-26
Abstract: The object is to convert sea (ocean) waves into mechanical energy. A ring floating on the water surface is used for this purpose. Located on said ring are deflecting blades which have an angle of attack and can be bent elastically about the vertical axis. In the event of a wave motion departing radially, the elastic blades have a blocking action, and in the event of an inwardly directed motion, said blades are open and impart a twist to the surface water. Located in the centre of the ring is a water turbine (hydroturbine), e.g. a Francis type, which converts the eddying flow into mechanical energy. <IMAGE>
Patent DE-3136783-A1 (DE)
Inventor: AKAZAWA YUKIO
IPC: H03M1/46
Filed: 1981-09-16
Abstract: The analog output from a local DAC comprising an LDAC and an MDAC, in which the full scale of the LDAC is always larger than the quantized level of the MDAC, is compared with an input analog signal which is sampled and held. A digital code obtained by successive approximation in accordance with the result of the comparison is stored in a successive approximation register. A shift code for calibrating the D/A conversion in the local DAC by shifting the digital code which is previously allotted to each digital code is stored in a shift code generating circuit (ROM). The digital code from the successive approximation register is digitally shifted in accordance with the shift code by a code shift circuit such as a digital adder/subtractor to obtain an A/D conversion output. An analog to digital converter with a high accuracy and an improved conversion speed is inexpensively fabricated in the form of a one chip LSI by a usual CMOS process.

Title: Drilling tool for producing an undercut widened portion in a blind hole
Inventor: KROENING WOLFGANG
IPC: B23B51/00
Filed: 1981-09-24
Abstract: The invention relates to a drilling tool for producing an undercut widened portion in a blind bore, with a drill shank in which a plunger extending beyond the drill shank is flexibly supported and guided in an axially displaceable manner. The plunger has sliding surfaces, diverging towards its free end, for drilling cutters which are held on the drill shank in such a way that they can be swung out. With a drilling tool of this type, undercut widened portions can be made in predrilled holes, e.g. in a concrete wall or the like, so that a plug, e.g. an expanding plug, inserted in the hole provided with the widened portion can be held in the hole in a positive-locking manner, the effect of which is to increase the bearing capacity of the plug. The object of the invention is to improve such a drilling tool in such a way that high impact and shock loads can readily be absorbed. To this end, the drilling cutters are rods guided in longitudinal slots of the drill shank and having mounted drill bits. The rod ends remote from the drill bits are mounted in an articulated manner and are supported directly on allocated end faces at the ends of the longitudinal slots. Furthermore, the sliding surfaces of the plunger also extend into the longitudinal slots.

Title: Arrangement for air-conditioning buildings, in particular stalls
Inventor: NETZER JUN FIDEL
IPC: A01K1/00
Filed: 1982-03-16
Abstract: An arrangement for air-conditioning stables contains a device for supplying possibly heated fresh air into the stable and in addition devices for cooling fresh air, which are arranged inside the stable and cool circulating air to a temperature which is lower in relation to the possibly warmed fresh air and conduct this cooled air into the manure region. As a result, the stable is to a large extent kept at a first temperature of for example 20 DEG C while there is a lower temperature, for example 15 DEG C, in the manure region. By air conditioning the manure region to a temperature which is lower than in the rest of the stable or in the living region, it is possible to keep the stable clean easily . <IMAGE>

Title: Device for use in a machine for forming metal workpieces with passages
Inventor: GJERKAAS EIGIL
IPC: B23P15/16
Filed: 1982-09-03
Abstract: Device for use in a machine for forming workpieces with passages, in particular workpieces which can be formed into soldering blowpipe tips and which, after the drilling of essentially longitudinal passages through the workpieces, are hammered by means of hammering members. The device has a bunch of pins which can be inserted into the passages in order to prevent partial or complete closing of the passages on account of the hammering operation. In order to facilitate the hammering operation and to eliminate the manual insertion of the pins into the passages and the manual transfer of the hammered workpiece and the pins clamped in place therein to a device for pulling out the pins, the pins are arranged in a guide tube and are axially displaceable in longitudinal grooves in the tube. At least one spring acts on the pins in order to produce a counter-force on the pins during the insertion of a workpiece and in order to make possible a feed movement during the hammering. A clutch is arranged between the guide tube and a machine spindle, in the centre of which the device can be placed.
