Title: Conveying device for steel profiles
Inventor: REGENBRECHT LUDWIG
IPC: B23D47/04
Filed: 1981-02-14
Abstract: The invention relates to a conveying device for steel profiles which are to be conveyed in their longitudinal direction, for which purpose they rest on table roller rollers. They are conveyed into the region of a processing machine which restricts the space perpendicular to the longitudinal extension of the steel profiles. This processing machine can, in particular, be a mitre saw. In order to permit reliable conveying and clamping of the stock even in the vicinity of the said saw while allowing pivoting, in particular of the mitre saw, into its set positions without hindrance, the invention provides in the region of the processing machine a pair of tension rollers, the axis of which extends perpendicularly to the axes of the table roller rollers. These tension rollers rest against vertical surfaces of the profiles. One of the tension rollers is driven. The tension rollers are furthermore adjustable relative to one another.

Patent DE-3132919-A1 (DE)
Title: Servo-drive
Inventor: RIESSLAND EBERHARD DIPL ING
IPC: B23Q1/52
Filed: 1981-08-20
Abstract: The invention relates to a servo-drive as used for testing semiconductor wafers on wafer samplers. It is used for making contact with the probe needle system by means of a rapid and bounce-free stroke movement, and for rotating the semiconductor wafer by any angle desired. In addition, the servo-drive has a further, continuous drive in the direction of said stroke movement, which drive is independent of the stroke movement. Thus it is possible to compensate for wafer thickness tolerances, as a result of which the measuring accuracy is improved.

Patent DE-3200847-A1 (DE)
Title: Nipple drinker, especially for young animals, preferably chicks
IPC: A01K39/02
Filed: 1982-01-14
Abstract: The invention relates to a nipple drinker, especially for young animals, preferably chicks, having a nipple pipe which guides the drinking liquid and is fitted at regular intervals with drinking nipples which release the drinking liquid and can be actuated by the animals. Nipple drinkers are used, especially in poultry keeping, to supply the animals with the necessary drinking water. Difficulties arise in breeding installations with the watering of young animals which have not yet learned to actuate the closure element of a drinking nipple, which can result in newly hatched chicks dying of thirst. The object of the invention is to improve a nipple drinker to the extent that the provision of inexperienced young animals, especially newly hatched chicks, with drinking liquid is guaranteed. This object has been achieved, according to the invention, in that selected drinking nipples possess, at their delivery mouth, a dripping element which keeps the closure open and in doing so delays the emergence of the drinking liquid. In this way the closure element remains opened and even the newly hatched chicks are supplied with water.

Title: Hydraulic lifting unit for integration in vehicles, etc.
Inventor: BIEBER HANS-GUENTER
IPC: B66F3/24
Filed: 1982-02-17
Abstract: Lifting unit included in vehicles and machines for lifting the same. Wheel change or assembly at the brake system is simplified. The unit can additionally be integrated in vehicles or machines. Depending on requirement, one to two units can be fitted per axle. Actuation is effected either manually, mechanically or electrohydraulically. The stroke directed against the ground is produced by a hydraulic pump. It is operated by the vehicle engine or by electric motor. These systems are in use. After change-over a two-way valve enables the pistons (a) to perform an upward stroke into the initial position. Two pistons increase the carrying capacity and stability. The pistons (b) contain a base plate (c) pivotable towards the ground. The pivoting capacity reduces torsion forces. The lifting unit can be equipped with one, two or more cylinders (d) according to requirement. The cylinders are arranged in a carrying system through which in vehicles the axle runs at an angle of 90 DEG . <IMAGE>

Title: Apparatus for the formation of rolled-wire and scrap bundles
Inventor: AMMERLING WILLI JUERGEN DR ING
IPC: B21C47/24
Filed: 1982-02-20
Abstract: The apparatus relates to the formation of wire bundles and scrap bundles from overlapped wire turns of a rolled extrusion which are supplied by a feed conveyor. The wire turns are collected on separate collecting mandrels to form wire bundles and bundles of scrap ends. The apparatus is to be improved in terms of the work cycle, to the effect that, even at a very high hourly production rate, two half wire bundles and, on a further collecting mandrel (21), the scrap ends are collected separated from one another from each rolled extrusion in each string. For this, there is a carriage (17) movable transversely relative to the collecting station (S) and having three collecting mandrels (19, 20, 21) which are arranged at the same distance from one another and which are movable alternately under the collecting station (S), and movable parallel to the longitudinal side of the carriage (17) symmetrically relative to the collecting station (S) and at double the distance between the mandrels are two extractor devices (27, 27a) which engage independently of one another into the region of the collecting mandrels and under the wire bundle (B). <IMAGE>

Title: Control arrangement for a self-commutated invertor with a DC intermediate circuit
Inventor: KUHN WERNER DIPL ING
IPC: H02M5/45
Filed: 1982-03-26
Abstract: In this control arrangement for a self-commutated invertor (5), operated using the pulse-width modulation method and having a DC intermediate circuit, the control commands for the converter valves of the invertor (5) are obtained by forming the intersection of a control voltage with an auxiliary voltage. The intermediate circuit voltage is input as a disturbance variable to a first multiplier (18) and, in order to improve the dynamic response, to a delay element (13). The first multiplier (18) multiplies an auxiliary voltage by the intermediate circuit voltage. The delay element (13) switches the intermediate circuit voltage through, with a delay, to a second multiplier (14) to which the control voltage for the invertor (5) is applied as a second factor. A corrected control voltage for forming the intersection with the auxiliary voltage emitted by the first multiplier (18) can be taken from the second multiplier (14) as the output variable. As a result of this disturbance variable connection of the intermediate circuit voltage for controlling the invertor (5), compensation processes in the intermediate circuit resulting from a change in the intermediate circuit voltage are prevented. The control arrangement can be used especially in the case of diesel-electric railway vehicles. <IMAGE>

Title: Device for analysing the energy of a gamma radiation
Inventor: RAPP WILHELM
IPC: G01T1/36
Filed: 1982-07-22
Abstract: The invention relates to a device for analysing the energy of a gamma radiation by means of a multiplicity of storage channels in which gamma ray pulses are sorted in dependence on their energy and stored as in a pulse amplitude analyser. In this arrangement, the output signals of a sorting circuit are connected to light-emitting diodes. A first light-emitting diode (3) in each case is arranged in one of a multiplicity of grooves (2) milled in a block (1). Each groove (2) is allocated to a discrete energy of the gamma radiation. The mutually parallel grooves are covered by instant photography paper (6) on which the light emitted by the light-emitting diodes (3) during the measuring time draws light bars, the length and brightness of which are in a fixed relationship to the duration and the intensity of the pulse occurring in an energy channel. Connecting loci of equal grey values on the developed photo indicates the curve of a spectrogram which is identical with that taken by a pulse amplitude analayser with the same number of channels. The arrangement according to the invention provides the possibility of identifying gamma radiation and documenting it which is sufficient for many cases, with relatively low expenditure. <IMAGE>

Filed: 1982-08-19
Abstract: Fig. 1 shows the circuit (6) of a refrigerant, which is fed to the swept volume (5) of a piston engine (1) by a metering pump (9) and is heated in the swept volume (5). This heating of the refrigerant results in its gasification, so that the piston (4) supported in the swept volume (5) is displaced and performs mechanical work. The refrigerant escaping from the swept volume (5) is then fed to a condenser (16), in which it is liquified. The liquified refrigerant is then fed to a refrigerant tank (7) lying upstream of the metering pump (9) to thence begin a new cycle. Heating of the refrigerant in the swept volume (5) is performed by means of a heat exchanger (21) enclosing the swept volume (5), through which exchanger warm water flows having a temperature of approximately 60 DEG  to 70 DEG C. <IMAGE>
